Our aim was to compare the inter-observer variability and diagnostic performance of the Breast Imaging Reporting and Data System (BI-RADS) lexicon for breast ultrasound of static and video images. Ninety-nine breast masses visible on ultrasound examination from 95 women 19-81 y of age at five institutions were enrolled in this study. They were scheduled to undergo biopsy or surgery or had been stable for at least 2 y of ultrasound follow-up after benign biopsy results or typically benign findings. For each mass, representative long- and short-axis static ultrasound images were acquired; real-time long- and short-axis B-mode video images through the mass area were separately saved as cine clips. Each image was reviewed independently by five radiologists who were asked to classify ultrasound features according to the fifth edition of the BI-RADS lexicon. Inter-observer variability was assessed using kappa (κ) statistics. Diagnostic performance on static and video images was compared using the area under the receiver operating characteristic curve. No significant difference was found in κ values between static and video images for all descriptors, although κ values of video images were higher than those of static images for shape, orientation, margin and calcifications. After receiver operating characteristic curve analysis, the video images (0.83, range: 0.77-0.87) had higher areas under the curve than the static images (0.80, range: 0.75-0.83; p = 0.08). Inter-observer variability and diagnostic performance of video images was similar to that of static images on breast ultrasonography according to the new edition of BI-RADS.

The metaphor of film and TV permeates the design of software to support video on the PC. Simply transplanting the non- interactive, sequential experience of film to the PC fails to exploit the virtues of the new context. Video ont eh PC should be interactive and non-sequential. This paper experiments with a variety of tools for using video on the PC that exploits the new content of the PC. Some feature are more successful than others. Applications that use these tools are explored, including primarily the home video archive but also streaming video servers on the Internet. The ability to browse, edit, abstract and index large volumes of video content such as home video and corporate video is a problem without appropriate solution in today's market. The current tools available are complex, unfriendly video editors, requiring hours of work to prepare a short home video, far more work that a typical home user can be expected to provide. Our proposed solution treats video like a text document, providing functionality similar to a text editor. Users can browse, interact, edit and compose one or more video sequences with the same ease and convenience as handling text documents. With this level of text-like composition, we call what is normally a sequential medium a 'video document'. An important component of the proposed solution is shot detection, the ability to detect when a short started or stopped. When combined with a spreadsheet of key frames, the host become a grid of pictures that can be manipulated and viewed in the same way that a spreadsheet can be edited. Multiple video documents may be viewed, joined, manipulated, and seamlessly played back. Abstracts of unedited video content can be produce automatically to create novel video content for export to other venues. Edited and raw video content can be published to the net or burned to a CD-ROM with a self-installing viewer for Windows 98 and Windows NT 4.0.

The aim of this study was to describe a modification of the Miyake-Apple posterior video analysis for the simultaneous visualization of the anterior and posterior corneal surfaces during wet laboratory-based deep anterior lamellar keratoplasty (DALK). A human donor corneoscleral button was affixed to a microscope slide and placed onto a custom-made mounting box. A big bubble DALK was performed on the cornea in the wet laboratory. An 11-diopter intraocular lens was positioned over the aperture of the back camera of an iPhone. This served to video record the posterior view of the corneoscleral button during the big bubble formation. An overhead operating microscope with an attached video camcorder recorded the anterior view during the surgery. The anterior and posterior views of the wet laboratory-based DALK surgery were simultaneously captured and edited using video editing software. The formation of the big bubble can be studied. This video recording camera system has the potential to act as a valuable research and teaching tool in corneal lamellar surgery, especially in the behavior of the big bubble formation in DALK.

How to facilitate efficient video manipulation and access in a web-based environment is becoming a popular trend for video applications. In this paper, we present a web-oriented video management and application processing system, based on our previous work on multimedia database and content-based retrieval. In particular, we extend the VideoMAP architecture with specific web-oriented mechanisms, which include: (1) Concurrency control facilities for the editing of video data among different types of users, such as Video Administrator, Video Producer, Video Editor, and Video Query Client; different users are assigned various priority levels for different operations on the database. (2) Versatile video retrieval mechanism which employs a hybrid approach by integrating a query-based (database) mechanism with content- based retrieval (CBR) functions; its specific language (CAROL/ST with CBR) supports spatio-temporal semantics of video objects, and also offers an improved mechanism to describe visual content of videos by content-based analysis method. (3) Query profiling database which records the `histories' of various clients' query activities; such profiles can be used to provide the default query template when a similar query is encountered by the same kind of users. An experimental prototype system is being developed based on the existing VideoMAP prototype system, using Java and VC++ on the PC platform.

Background Low rates of colorectal cancer (CRC) screening persist due to individual, provider and system level barriers. Purpose To develop and obtain initial feedback about a CRC screening educational video from community members and medical professionals. Methods Focus groups of patients were conducted prior to the development of an educational video and focus groups of patients provided initial feedback about the developed CRC screening educational video. Medical personnel reviewed the video and made recommendations prior to final editing of the video. Results Patients identified CRC screening barriers and made suggestions about the information to include in the educational video. Their suggestions included using a healthcare provider to state the importance of completing CRC screening, demonstrate how to complete the fecal occult blood test, and that men and women from diverse ethnic groups and races could be included in the same video. Participants reviewed the developed video and mentioned that their suggestions were portrayed correctly, the video was culturally appropriate, and the information presented in the video was easy to understand. Medical personnel made suggestions on ways to improve the content and the delivery of the medical information prior to final editing of the video. Discussion Participants provided valuable information in the development of an educational video to improve patient knowledge and patient-provider communication about CRC screening. The educational video developed was based on the Protection Motivation Theory and addressed the colon cancer screening barriers identified in this mostly minority and low-income patient population. Future research will determine if CRC screening increases among patients who watch the educational video. Translation to Health Education Practice Educational videos can provide important information about CRC and CRC screening to average-risk adults. PMID:20209024

Video personalization for usage environment

Tseng, Belle L.; Lin, Ching-Yung; Smith, John R.

2002-07-01

A video personalization and summarization system is designed and implemented incorporating usage environment to dynamically generate a personalized video summary. The personalization system adopts the three-tier server-middleware-client architecture in order to select, adapt, and deliver rich media content to the user. The server stores the content sources along with their corresponding MPEG-7 metadata descriptions. Our semantic metadata is provided through the use of the VideoAnnEx MPEG-7 Video Annotation Tool. When the user initiates a request for content, the client communicates the MPEG-21 usage environment description along with the user query to the middleware. The middleware is powered by the personalization engine and the content adaptation engine. Our personalization engine includes the VideoSue Summarization on Usage Environment engine that selects the optimal set of desired contents according to user preferences. Afterwards, the adaptation engine performs the required transformations and compositions of the selected contents for the specific usage environment using our VideoEd Editing and Composition Tool. Finally, two personalization and summarization systems are demonstrated for the IBM Websphere Portal Server and for the pervasive PDA devices.

A properly performed fiberoptic endoscopic evaluation of swallowing (FEES®) is comprehensive and time-consuming. Editing times of FEES protocols and attempts for efficiency maximization are unknown. Here, the protocol editing times of completed FEES examinations were determined. The present study reports the time savings and quality gains of a newly developed documentation system tailored to the FEES standard of Langmore. Four independent examiners analyzed twelve videos of FEES procedures, six without and six with the documentation system. Effectiveness of the documentation system was evaluated according to the times for total evaluation, interpretation, documentation, report writing, and for report completeness. The documentation system reduced editing times and increased report completeness with large effect sizes. Averaged total evaluation time decreased from 42 to 27 min, report completeness increased from 55 to 80%. The use of the documentation system facilitates and improves the assessment of the swallowing process. PMID:20938202

To study the utility of a commercially available small, portable ultra-high definition (HD) camera (GoPro Hero 4) for intraoperative recording. A head mount was used to fix the camera on the operating surgeon's head. Due care was taken to protect the patient's identity. The recorded video was subsequently edited and used as a teaching tool. This retrospective, noncomparative study was conducted at three tertiary eye care centers. The surgeries recorded were ptosis correction, ectropion correction, dacryocystorhinostomy, angular dermoid excision, enucleation, blepharoplasty and lid tear repair surgery (one each). The recorded videos were reviewed, edited, and checked for clarity, resolution, and reproducibility. The recorded videos were found to be high quality, which allowed for zooming and visualization of the surgical anatomy clearly. Minimal distortion is a drawback that can be effectively addressed during postproduction. The camera, owing to its lightweight and small size, can be mounted on the surgeon's head, thus offering a unique surgeon point-of-view. In our experience, the results were of good quality and reproducible. A head-mounted ultra-HD video recording system is a cheap, high quality, and unobtrusive technique to record surgery and can be a useful teaching tool in external facial and ophthalmic plastic surgery.

This paper addresses a solution to the problem of scene estimation of motion video data in the fuzzy set theoretic framework. Using fuzzy image feature extractors, a new algorithm is developed to compute the change of information in each of two successive frames to classify scenes. This classification process of raw input visual data can be used to establish structure for correlation. The algorithm attempts to fulfill the need for nonlinear, frame-accurate access to video data for applications such as video editing and visual document archival/retrieval systems in multimedia environments.

In order to develop an e-learning system that promotes self-learning, lectures and basic operations in laboratory practice of chemistry were recorded and edited on DVD media, consisting of 8 streaming videos as learning materials. Twenty-six students wanted to watch the DVD, and answered the following questions after they had watched it: "Do you think the video would serve to encourage you to study independently in the laboratory practice?" Almost all students (95%) approved of its usefulness, and more than 60% of them watched the videos repeatedly in order to acquire deeper knowledge and skill of the experimental operations. More than 60% answered that the demonstration-experiment should be continued in the laboratory practice, in spite of distribution of the DVD media.

A model space positioning system (MSPS), a state-of-the-art, real-time tracking system to provide the test engineer with on line model pitch and spin rate information, is described. It is noted that the six-degree-of-freedom post processor program will require additional programming effort both in the automated tracking mode for high spin rates and in accuracy to meet the measurement objectives. An independent multicamera system intended to augment the MSPS is studied using laboratory calibration methods based on photogrammetry to characterize the losses in various recording options. Data acquired to Super VHS tape encoded with Vertical Interval Time Code and transcribed to video disk are considered to be a reasonable priced choice for post editing and processing video data.

2016-10-01

Video recordings of surgical procedures are an excellent tool for presentations, analyzing self-performance, illustrating publications, and educating surgeons and patients. Recording the surgeon's perspective with high-resolution video in the operating room or clinic has become readily available and advances in software improve the ease of editing these videos. A GoPro HERO 4 Silver or Black was mounted on a head strap and worn over the surgical scrub cap, above the loupes of the operating surgeon. Five live surgical cases were recorded with the camera. The videos were uploaded to a computer and subsequently edited with iMovie or the GoPro software. The optimal settings for both the Silver and Black editions, when operating room lights are used, were determined to be a narrow view, 1080p, 60 frames per second (fps), spot meter on, protune on with auto white balance, exposure compensation at -0.5, and without a polarizing lens. When the operating room lights were not used, it was determined that the standard settings for a GoPro camera were ideal for positioning and editing (4K, 15 frames per second, spot meter and protune off). The GoPro HERO 4 provides high-quality, the surgeon perspective, and a cost-effective video recording of upper extremity surgical procedures. Challenges include finding the optimal settings for each surgical procedure and the length of recording due to battery life limitations. Copyright © 2016 American Society for Surgery of the Hand.

GoPro and Google Glass technology have previously been used to record procedures in ophthalmology and other medical fields. In this manuscript, GoPro's latest HERO 4 Black edition camera (GoPro Inc, San Mateo, Calif.) will be used to record the placement of a scleral buckle during retinal detachment surgery. GoPro HERO 4 Black edition camera, which records 4K-quality video with a resolution of 3840 (pixels) x 2160 (lines), was mounted on a head strap to record placement of a scleral buckle for a retinal detachment. Excellent video quality was achieved with the 4K SuperView setting. Bluetooth connection with an Apple iPad (Apple Inc, Cupertino, Calif.) provided live streaming and use of the GoPro App. Zoom, horizontal/vertical alignment, exposure, and contrast adjustments were made with postproduction editing on GoPro Studio software. Video recording with the GoPro HERO 4 Black edition camera is an excellent way to document extraocular procedures to improve medical education, self-training, or medicolegal documentation.

Storage, retrieval, and edit of digital video using Motion JPEG

In a companion paper we describe a Micro Channel adapter card that can perform real-time JPEG (Joint Photographic Experts Group) compression of a 640 by 480 24-bit image within 1/30th of a second. Since this corresponds to NTSC video rates at considerably good perceptual quality, this system can be used for real-time capture and manipulation of continuously fed video. To facilitate capturing the compressed video in a storage medium, an IBM Bus master SCSI adapter with cache is utilized. Efficacy of the data transfer mechanism is considerably improved using the System Control Block architecture, an extension to Micro Channel bus masters. We show experimental results that the overall system can perform at compressed data rates of about 1.5 MBytes/second sustained and with sporadic peaks to about 1.8 MBytes/second depending on the image sequence content. We also describe mechanisms to access the compressed data very efficiently through special file formats. This in turn permits creation of simpler sequence editors. Another advantage of the special file format is easy control of forward, backward and slow motion playback. The proposed method can be extended for design of a video compression subsystem for a variety of personal computing systems.

2003-02-01

Documentation of surgical procedures is limited to the accuracy of description, which depends on the vocabulary and the descriptive prowess of the surgeon. Even analog video recording could not solve the problem of documentation satisfactorily due to the abundance of recorded material. By capturing the video digitally, most problems are solved in the circumstances described in this article. We developed a cheap and useful digital video capturing system that consists of conventional computer components. Video images and clips can be captured intraoperatively and are immediately available. The system is a commercial personal computer specially configured for digital video capturing and is connected by wire to the video tower. Filming was done with a conventional endoscopic video camera. A total of 65 open and endoscopic procedures were documented in an orthopedic and a thoracic surgery unit. The median number of clips per surgical procedure was 6 (range, 1-17), and the median storage volume was 49 MB (range, 3-360 MB) in compressed form. The median duration of a video clip was 4 min 25 s (range, 45 s to 21 min). Median time for editing a video clip was 12 min for an advanced user (including cutting, title for the movie, and compression). The quality of the clips renders them suitable for presentations. This digital video documentation system allows easy capturing of intraoperative video sequences in high quality. All possibilities of documentation can be performed. With the use of an endoscopic video camera, no compromises with respect to sterility and surgical elbowroom are necessary. The cost is much lower than commercially available systems, and setting changes can be performed easily without trained specialists.

[Influence of different lighting levels at workstations with video display terminals on operators' work efficiency].

2003-01-01

The aim of this work was to evaluate the influence of different lighting levels at workstations with video display terminals (VDTs) on the course of the operators' visual work, and to determine the optimal levels of lighting at VDT workstations. For two kinds of job (entry of figures from a typescript and edition of the text displayed on the screen), the work capacity, the degree of the visual strain and the operators' subjective symptoms were determined for four lighting levels (200, 300, 500 and 750 lx). It was found that the work at VDT workstations may overload the visual system and cause eyes complaints as well as the reduction of accommodation or convergence strength. It was also noted that the edition of the text displayed on the screen is more burdening for operators than the entry of figures from a typescript. Moreover, the examination results showed that the lighting at VDT workstations should be higher than 200 lx and that 300 lx makes the work conditions most comfortable during the entry of figures from a typescript, and 500 lx during the edition of the text displayed on the screen.

2015-02-01

Significant improvements can be made in recoding surgical procedures, particularly in capturing high-quality video recordings from the surgeons' point of view. This study examined the utility of the GoPro HERO 3+ Black Edition camera for high-definition, point-of-view recordings of plastic and reconstructive surgery. The GoPro HERO 3+ Black Edition camera was head-mounted on the surgeon and oriented to the surgeon's perspective using the GoPro App. The camera was used to record 4 cases: 2 fat graft procedures and 2 breast reconstructions. During cases 1-3, an assistant remotely controlled the GoPro via the GoPro App. For case 4 the GoPro was linked to a WiFi remote, and controlled by the surgeon. Camera settings for case 1 were as follows: 1080p video resolution; 48 fps; Protune mode on; wide field of view; 16:9 aspect ratio. The lighting contrast due to the overhead lights resulted in limited washout of the video image. Camera settings were adjusted for cases 2-4 to a narrow field of view, which enabled the camera's automatic white balance to better compensate for bright lights focused on the surgical field. Cases 2-4 captured video sufficient for teaching or presentation purposes. The GoPro HERO 3+ Black Edition camera enables high-quality, cost-effective video recording of plastic and reconstructive surgery procedures. When set to a narrow field of view and automatic white balance, the camera is able to sufficiently compensate for the contrasting light environment of the operating room and capture high-resolution, detailed video.

This study describes the instructional approach of using student-created video documentaries as projects in an undergraduate non-science majors' Energy Perspectives science course. Four years of teaching this course provided many reflective teaching moments from which we have enhanced our instructional approach to teaching students how to construct a quality Ken Burn's style science video. Fundamental to a good video documentary is the story told via a narrative which involves significant writing, editing and rewriting. Many students primarily associate a video documentary with visual imagery and do not realize the importance of writing in the production of the video. Required components of the student-created video include: 1) select a topic, 2) conduct research, 3) write an outline, 4) write a narrative, 5) construct a project storyboard, 6) shoot or acquire video and photos (from legal sources), 7) record the narrative, 8) construct the video documentary, 9) edit and 10) finalize the project. Two knowledge survey instruments (administered pre- and post) were used for assessment purposes. One survey focused on the skills necessary to research and produce video documentaries and the second survey assessed students' content knowledge acquired from each documentary. This talk will focus on the components necessary for video documentaries and the instructional lessons learned over the years. Additionally, results from both surveys and student reflections of the video project will be shared.

To improve the state-of-the-art teaching system by creating surgical videos with synchronised vertical 2-split screens. An ultra-compact, wide-angle point-of-view camcorder (HX-A1, Panasonic) was mounted on the surgical microscope focusing mostly on the surgeons' hand movements. In combination with the regular surgical videos obtained from the CCD camera in the surgical microscope, synchronised vertical 2-split-screen surgical videos were generated with the video-editing software. Using synchronised vertical 2-split-screen videos, residents of the ophthalmology department could watch and learn how assistant surgeons controlled the eyeball, while the main surgeons performed scleral buckling surgery. In vitrectomy, the synchronised vertical 2-split-screen videos showed the surgeons' hands holding the instruments and moving roughly and boldly, in contrast to the very delicate movements of the vitrectomy instruments inside the eye. Synchronised vertical 2-split-screen surgical videos are beneficial for the education of young surgical trainees when learning surgical skills including the surgeons' hand movements. © 2015 S.

The expansion of the home video market has created a requirement for video editing tools to allow ordinary people to assemble videos from short clips. However, professional skills are still necessary to create a music video, which requires a stream to be synchronized with pre-composed music. Because the music and the video are pre-generated in separate environments, even a professional producer usually requires a number of trials to obtain a satisfactory synchronization, which is something that most amateurs are unable to achieve.

Graves, Steven Nicholas; Shenaq, Deana Saleh; Langerman, Alexander J.

2015-01-01

Background: Significant improvements can be made in recoding surgical procedures, particularly in capturing high-quality video recordings from the surgeons’ point of view. This study examined the utility of the GoPro HERO 3+ Black Edition camera for high-definition, point-of-view recordings of plastic and reconstructive surgery. Methods: The GoPro HERO 3+ Black Edition camera was head-mounted on the surgeon and oriented to the surgeon’s perspective using the GoPro App. The camera was used to record 4 cases: 2 fat graft procedures and 2 breast reconstructions. During cases 1-3, an assistant remotely controlled the GoPro via the GoPro App. For case 4 the GoPro was linked to a WiFi remote, and controlled by the surgeon. Results: Camera settings for case 1 were as follows: 1080p video resolution; 48 fps; Protune mode on; wide field of view; 16:9 aspect ratio. The lighting contrast due to the overhead lights resulted in limited washout of the video image. Camera settings were adjusted for cases 2-4 to a narrow field of view, which enabled the camera’s automatic white balance to better compensate for bright lights focused on the surgical field. Cases 2-4 captured video sufficient for teaching or presentation purposes. Conclusions: The GoPro HERO 3+ Black Edition camera enables high-quality, cost-effective video recording of plastic and reconstructive surgery procedures. When set to a narrow field of view and automatic white balance, the camera is able to sufficiently compensate for the contrasting light environment of the operating room and capture high-resolution, detailed video.

Evaluation of stereoscopic medical video content on an autostereoscopic display for undergraduate medical education

NASA Astrophysics Data System (ADS)

Ilgner, Justus F. R.; Kawai, Takashi; Shibata, Takashi; Yamazoe, Takashi; Westhofen, Martin

2006-02-01

Introduction: An increasing number of surgical procedures are performed in a microsurgical and minimally-invasive fashion. However, the performance of surgery, its possibilities and limitations become difficult to teach. Stereoscopic video has evolved from a complex production process and expensive hardware towards rapid editing of video streams with standard and HDTV resolution which can be displayed on portable equipment. This study evaluates the usefulness of stereoscopic video in teaching undergraduate medical students. Material and methods: From an earlier study we chose two clips each of three different microsurgical operations (tympanoplasty type III of the ear, endonasal operation of the paranasal sinuses and laser chordectomy for carcinoma of the larynx). This material was added by 23 clips of a cochlear implantation, which was specifically edited for a portable computer with an autostereoscopic display (PC-RD1-3D, SHARP Corp., Japan). The recording and synchronization of left and right image was performed at the University Hospital Aachen. The footage was edited stereoscopically at the Waseda University by means of our original software for non-linear editing of stereoscopic 3-D movies. Then the material was converted into the streaming 3-D video format. The purpose of the conversion was to present the video clips by a file type that does not depend on a television signal such as PAL or NTSC. 25 4th year medical students who participated in the general ENT course at Aachen University Hospital were asked to estimate depth clues within the six video clips plus cochlear implantation clips. Another 25 4th year students who were shown the material monoscopically on a conventional laptop served as control. Results: All participants noted that the additional depth information helped with understanding the relation of anatomical structures, even though none had hands-on experience with Ear, Nose and Throat operations before or during the course. The monoscopic group generally estimated resection depth to much lesser values than in reality. Although this was the case with some participants in the stereoscopic group, too, the estimation of depth features reflected the enhanced depth impression provided by stereoscopy. Conclusion: Following first implementation of stereoscopic video teaching, medical students who are inexperienced with ENT surgical procedures are able to reproduce depth information and therefore anatomically complex structures to a greater extent following stereoscopic video teaching. Besides extending video teaching to junior doctors, the next evaluation step will address its effect on the learning curve during the surgical training program.

Dimitrova, Nevenka; Abdel-Mottaleb, Mohamed

1997-01-01

This paper presents a novel approach for video retrieval from a large archive of MPEG or Motion JPEG compressed video clips. We introduce a retrieval algorithm that takes a video clip as a query and searches the database for clips with similar contents. Video clips are characterized by a sequence of representative frame signatures, which are constructed from DC coefficients and motion information (`DC+M' signatures). The similarity between two video clips is determined by using their respective signatures. This method facilitates retrieval of clips for the purpose of video editing, broadcast news retrieval, or copyright violation detection.

The Global Operative Assessment of Laparoscopic Skill (GOALS) is one validated metric utilized to grade laparoscopic skills and has been utilized to score recorded operative videos. To facilitate easier viewing of these recorded videos, we are developing novel techniques to enable surgeons to view these videos. The objective of this study is to determine the feasibility of utilizing widespread current consumer-based technology to assist in distributing appropriate videos for objective evaluation. Videos from residents were recorded via a direct connection from the camera processor via an S-video output via a cable into a hub to connect to a standard laptop computer via a universal serial bus (USB) port. A standard consumer-based video editing program was utilized to capture the video and record in appropriate format. We utilized mp4 format, and depending on the size of the file, the videos were scaled down (compressed), their format changed (using a standard video editing program), or sliced into multiple videos. Standard available consumer-based programs were utilized to convert the video into a more appropriate format for handheld personal digital assistants. In addition, the videos were uploaded to a social networking website and video sharing websites. Recorded cases of laparoscopic cholecystectomy in a porcine model were utilized. Compression was required for all formats. All formats were accessed from home computers, work computers, and iPhones without difficulty. Qualitative analyses by four surgeons demonstrated appropriate quality to grade for these formats. Our preliminary results show promise that, utilizing consumer-based technology, videos can be easily distributed to surgeons to grade via GOALS via various methods. Easy accessibility may help make evaluation of resident videos less complicated and cumbersome.

McEachen, James C; Cusack, Thomas J; McEachen, John C

2003-08-01

Digitizing images for use in case presentations based on hardcopy films, slides, photographs, negatives, books, and videos can present a challenging task. Scanners and digital cameras have become standard tools of the trade. Unfortunately, use of these devices to digitize multiple images in many different media formats can be a time-consuming and in some cases unachievable process. The authors' goal was to create a PC-based solution for digitizing multiple media formats in a timely fashion while maintaining adequate image presentation quality. The authors' PC-based solution makes use of off-the-shelf hardware applications to include a digital document camera (DDC), VHS video player, and video-editing kit. With the assistance of five staff radiologists, the authors examined the quality of multiple image types digitized with this equipment. The authors also quantified the speed of digitization of various types of media using the DDC and video-editing kit. With regard to image quality, the five staff radiologists rated the digitized angiography, CT, and MR images as adequate to excellent for use in teaching files and case presentations. With regard to digitized plain films, the average rating was adequate. As for performance, the authors recognized a 68% improvement in the time required to digitize hardcopy films using the DDC instead of a professional quality scanner. The PC-based solution provides a means for digitizing multiple images from many different types of media in a timely fashion while maintaining adequate image presentation quality.

This paper presents a generalized approach to data entry and editing utilizing formatted video computer terminals. The purpose of the system developed is to facilitate the creation of many small data bases, with a minimum of implementation time, while maintaining extensive editing capability and preserving ease of use by data entry personnel. RPMIS has demonstrated its utility in shortening the time between research activities and clinical application of results. The system allows entry and retrieval of overlapping subsets of the patient's record in an order and format most appropriate to the individual application. It is used for production of synoptic presentations of information from the labs, the ward and the clinic. RPMIS was designed for the clinical trials setting and has been well received and implemented for numerous such studies. Additional uses have included several registries, screening clinics, retrospective studies, and epidemiologic investigations. The system has found fortuitous use in maintaining curriculum vitae, publications lists and continuing medical education credits.

Producing Videotape Programs for Computer Training: An Example with AMA/NET

PubMed Central

Novey, Donald W.

1990-01-01

To facilitate user proficiency with AMA/Net, an 80-minute training videotape has been produced. The production was designed to use videotape's advantages, where information and emotion are combined; and to accommodate its chief disadvantage, lack of resolution for fine text, with close-ups and graphics. Content of the videotape was conceived, out-lined, demonstrated with simultaneous text capture, edited into script form, narration added, and scripts marked for videotaping and narrating. Videotaping was performed with actual keyboard sounds for realism. The recording was divided into four areas: office mock-up, keyboard close-ups, scan-conversion and screen close-ups. Once the footage was recorded, it was logged and rough-edited. Care was taken to balance the pace of the program with visual stimulation and amount of narration. The final edit was performed as a culmination of all scripts, video materials and rough edit, with graphics and steady change of visual information offsetting the static nature of the screen display. Carefully planned video programs can be a useful and economical adjunct in the training process for online services.

2009-01-01

Biology laboratory classes are designed to teach concepts and techniques through experiential learning. Students who have never performed a technique must be guided through the process, which is often difficult to standardize across multiple lab sections. Visual demonstration of laboratory procedures is a key element in teaching pedagogy. The main goals of the study were to create videos explaining and demonstrating a variety of lab techniques that would serve as teaching tools for undergraduate and graduate lab courses and to assess the impact of these videos on student learning. Demonstrations of individual laboratory procedures were videotaped and then edited with iMovie. Narration for the videos was edited with Audacity. Undergraduate students were surveyed anonymously prior to and following screening to assess the impact of the videos on student lab performance by completion of two Participant Perception Indicator surveys. A total of 203 and 171 students completed the pre- and posttesting surveys, respectively. Statistical analyses were performed to compare student perceptions of knowledge of, confidence in, and experience with the lab techniques before and after viewing the videos. Eleven demonstrations were recorded. Chi-square analysis revealed a significant increase in the number of students reporting increased knowledge of, confidence in, and experience with the lab techniques after viewing the videos. Incorporation of instructional videos as prelaboratory exercises has the potential to standardize techniques and to promote successful experimental outcomes.

Automated Production of Movies on a Cluster of Computers

NASA Technical Reports Server (NTRS)

Nail, Jasper; Le, Duong; Nail, William L.; Nail, William

2008-01-01

A method of accelerating and facilitating production of video and film motion-picture products, and software and generic designs of computer hardware to implement the method, are undergoing development. The method provides for automation of most of the tedious and repetitive tasks involved in editing and otherwise processing raw digitized imagery into final motion-picture products. The method was conceived to satisfy requirements, in industrial and scientific testing, for rapid processing of multiple streams of simultaneously captured raw video imagery into documentation in the form of edited video imagery and video derived data products for technical review and analysis. In the production of such video technical documentation, unlike in production of motion-picture products for entertainment, (1) it is often necessary to produce multiple video derived data products, (2) there are usually no second chances to repeat acquisition of raw imagery, (3) it is often desired to produce final products within minutes rather than hours, days, or months, and (4) consistency and quality, rather than aesthetics, are the primary criteria for judging the products. In the present method, the workflow has both serial and parallel aspects: processing can begin before all the raw imagery has been acquired, each video stream can be subjected to different stages of processing simultaneously on different computers that may be grouped into one or more cluster(s), and the final product may consist of multiple video streams. Results of processing on different computers are shared, so that workers can collaborate effectively.

Applications of ENF criterion in forensic audio, video, computer and telecommunication analysis.

PubMed

Grigoras, Catalin

2007-04-11

This article reports on the electric network frequency criterion as a means of assessing the integrity of digital audio/video evidence and forensic IT and telecommunication analysis. A brief description is given to different ENF types and phenomena that determine ENF variations. In most situations, to reach a non-authenticity opinion, the visual inspection of spectrograms and comparison with an ENF database are enough. A more detailed investigation, in the time domain, requires short time windows measurements and analyses. The stability of the ENF over geographical distances has been established by comparison of synchronized recordings made at different locations on the same network. Real cases are presented, in which the ENF criterion was used to investigate audio and video files created with secret surveillance systems, a digitized audio/video recording and a TV broadcasted reportage. By applying the ENF Criterion in forensic audio/video analysis, one can determine whether and where a digital recording has been edited, establish whether it was made at the time claimed, and identify the time and date of the registering operation.

CRISPR-Cas9 technology would be enhanced by the ability to inhibit Cas9 function spatially, temporally, or conditionally. Previously, we discovered small proteins encoded by bacteriophages that inhibit the CRISPR-Cas systems of their host bacteria. These "anti-CRISPRs" were specific to type I CRISPR-Cas systems that do not employ the Cas9 protein. We posited that nature would also yield Cas9 inhibitors in response to the evolutionary arms race between bacteriophages and their hosts. Here, we report the discovery of three distinct families of anti-CRISPRs that specifically inhibit the CRISPR-Cas9 system of Neisseria meningitidis. We show that these proteins bind directly to N. meningitidis Cas9 (NmeCas9) and can be used as potent inhibitors of genome editing by this system in human cells. These anti-CRISPR proteins now enable "off-switches" for CRISPR-Cas9 activity and provide a genetically encodable means to inhibit CRISPR-Cas9 genome editing in eukaryotes. VIDEO ABSTRACT.

Facial Video-Based Photoplethysmography to Detect HRV at Rest.

PubMed

Moreno, J; Ramos-Castro, J; Movellan, J; Parrado, E; Rodas, G; Capdevila, L

2015-06-01

Our aim is to demonstrate the usefulness of photoplethysmography (PPG) for analyzing heart rate variability (HRV) using a standard 5-min test at rest with paced breathing, comparing the results with real RR intervals and testing supine and sitting positions. Simultaneous recordings of R-R intervals were conducted with a Polar system and a non-contact PPG, based on facial video recording on 20 individuals. Data analysis and editing were performed with individually designated software for each instrument. Agreement on HRV parameters was assessed with concordance correlations, effect size from ANOVA and Bland and Altman plots. For supine position, differences between video and Polar systems showed a small effect size in most HRV parameters. For sitting position, these differences showed a moderate effect size in most HRV parameters. A new procedure, based on the pixels that contained more heart beat information, is proposed for improving the signal-to-noise ratio in the PPG video signal. Results were acceptable in both positions but better in the supine position. Our approach could be relevant for applications that require monitoring of stress or cardio-respiratory health, such as effort/recuperation states in sports. © Georg Thieme Verlag KG Stuttgart · New York.

Virtual Environments Using Video Capture for Social Phobia with Psychosis

White, Richard; Clarke, Timothy; Turner, Ruth; Fowler, David

2013-01-01

Abstract A novel virtual environment (VE) system was developed and used as an adjunct to cognitive behavior therapy (CBT) with six socially anxious patients recovering from psychosis. The novel aspect of the VE system is that it uses video capture so the patients can see a life-size projection of themselves interacting with a specially scripted and digitally edited filmed environment played in real time on a screen in front of them. Within-session process outcomes (subjective units of distress and belief ratings on individual behavioral experiments), as well as patient feedback, generated the hypothesis that this type of virtual environment can potentially add value to CBT by helping patients understand the role of avoidance and safety behaviors in the maintenance of social anxiety and paranoia and by boosting their confidence to carry out “real-life” behavioral experiments.

The idea of synchronizing multiple video recordings to some type of 'range' time has been tried to varying degrees of success in the past. Combining this requirement with existing time code standards (SMPTE) and the new innovations in desktop multimedia however, have afforded an opportunity to increase the flexibility and usefulness of such efforts without adding costs over the traditional data recording and reduction systems. The concept described can use IRIG, GPS or a battery backed internal clock as the master time source. By converting that time source to Vertical Interval Time Code or Longitudinal Time Code, both in accordance with the SMPTE standards, the user will obtain a tape that contains machine/computer readable time code suitable for use with editing equipment that is available off-the-shelf. Accuracy on playback is then determined by the playback system chosen by the user. Accuracies of +/- 2 frames are common among inexpensive systems and complete frame accuracy is more a matter of the users' budget than the capability of the recording system.

Science documentary video slides to enhance education and communication

2010-12-01

Documentary production can convey powerful messages using a combination of authentic science and reinforcing video imagery. Conventional documentary production contains too much information for many viewers to follow; hence many powerful points may be lost. But documentary productions that are re-edited into short video sequences and made available through web based video servers allow the teacher/viewer to access the material as video slides. Each video slide contains one critical discussion segment of the larger documentary. A teacher/viewer can review the documentary one segment at a time in a class room, public forum, or in the comfort of home. The sequential presentation of the video slides allows the viewer to best absorb the documentary message. The website environment provides space for additional questions and discussion to enhance the video message.

Video disk technology is one of the central themes of a technology demonstrator workstation being assembled as a man/machine interface for the Space Station Data Management Test Bed at Johnson Space Center. Langley Research Center personnel involved in the conception and implementation of this workstation have assembled a video production facility to allow production of video disk material for this propose. This paper documents the initial familiarization efforts in the field of video production for those personnel and that facility. Although the entire video disk production cycle was not operational for this initial effort, the production of a simulated disk on video tape did acquaint the personnel with the processes involved and with the operation of the hardware. Invaluable experience in storyboarding, script writing, audio and video recording, and audio and video editing was gained in the production process.

2013-12-01

Dartmouth's NSF-supported IGERT Polar Environmental Change graduate program has focused on using video media to foster interdisciplinary thinking and to improve student skills in science communication and public outreach. Researchers, educators, and funding organizations alike recognize the value of video media for making research results more accessible and relevant to diverse audiences and across cultures. We present an affordable equipment set and the basic video training needed as well as available Dartmouth institutional support systems for students to produce outreach videos on climate change and its associated impacts on people. We highlight and discuss the successes and challenges of producing three types of video products created by graduate and undergraduate students affiliated with the Dartmouth IGERT. The video projects created include 1) graduate student profile videos, 2) a series of short student-created educational videos for Greenlandic high school students, and 3) an outreach video about women in science based on the experiences of women students conducting research during the IGERT field seminar at Summit Station and Kangerlussuaq, Greenland. The 'Science in Greenland--It's a Girl Thing' video was featured on The New York Times Dot Earth blog and the Huffington Post Green blog among others and received international recognition. While producing these videos, students 1) identified an audience and created story lines, 2) worked in front of and behind the camera, 3) utilized low-cost digital editing applications, and 4) shared the videos on multiple platforms from social media to live presentations. The three video projects were designed to reach different audiences, and presented unique challenges for content presentation and dissemination. Based on student and faculty assessment, we conclude that the video projects improved student science communication skills and increased public knowledge of polar science and the effects of climate change.

Visualizing the complex anatomy of vascular and biliary structures of the liver on a case-by-case basis has been challenging. A living donor liver transplant (LDLT) right hepatectomy case, with focus on the porta hepatis, was used to demonstrate an innovative method to visualize anatomy with the purpose of refining preoperative planning and teaching of complex surgical procedures. The production of an animation-enhanced video consisted of many stages including the integration of pre-surgical planning; case-specific footage and 3D models of the liver and associated vasculature, reconstructed from contrast-enhanced CTs. Reconstructions of the biliary system were modeled from intraoperative cholangiograms. The distribution of the donor portal veins, hepatic arteries and bile ducts was defined from the porta hepatis intrahepatically to the point of surgical division. Each step of the surgery was enhanced with 3D animation to provide sequential and seamless visualization from pre-surgical planning to outcome. Use of visualization techniques such as transparency and overlays allows viewers not only to see the operative field, but also the origin and course of segmental branches and their spatial relationships. This novel educational approach enables integrating case-based operative footage with advanced editing techniques for visualizing not only the surgical procedure, but also complex anatomy such as vascular and biliary structures. The surgical team has found this approach to be beneficial for preoperative planning and clinical teaching, especially for complex cases. Each animation-enhanced video case is posted to the open-access Toronto Video Atlas of Surgery (TVASurg), an education resource with a global clinical and patient user base. The novel educational system described in this paper enables integrating operative footage with 3D animation and cinematic editing techniques for seamless sequential organization from pre-surgical planning to outcome.

The Interactive Presentation Development System (IPFS) is a highly interactive system for creating, editing, and displaying video presentation sequences, e.g., for developing and presenting displays of instructional material similiar to overhead transparency or slide presentations. However, since this system is PC-based, users (instructors) can step through sequences forward or backward, focusing attention to areas of the display with special cursor pointers. Additionally, screen displays may be dynamically modified during the presentation to show assignments or to answer questions, much like a traditional blackboard. This system is now implemented at the University of Southwestern Louisiana for use within the piloting phases of the NASA contract work.

While movie edition creates a discontinuity in audio-visual works for narrative and economy-of-storytelling reasons, eyeblink creates a discontinuity in visual perception for protective and cognitive reasons. We were interested in analyzing eyeblink rate linked to cinematographic edition styles. We created three video stimuli with different editing styles and analyzed spontaneous blink rate in participants (N = 40). We were also interested in looking for different perceptive patterns in blink rate related to media professionalization. For that, of our participants, half (n = 20) were media professionals, and the other half were not. According to our results, MTV editing style inhibits eyeblinks more than Hollywood style and one-shot style. More interestingly, we obtained differences in visual perception related to media professionalization: we found that media professionals inhibit eyeblink rate substantially compared with non-media professionals, in any style of audio-visual edition.

Novel Uses of Video to Accelerate the Surgical Learning Curve.

PubMed

Ibrahim, Andrew M; Varban, Oliver A; Dimick, Justin B

2016-04-01

Surgeons are under enormous pressure to continually improve and learn new surgical skills. Novel uses of surgical video in the preoperative, intraoperative, and postoperative setting are emerging to accelerate the learning curve of surgical skill and minimize harm to patients. In the preoperative setting, social media outlets provide a valuable platform for surgeons to collaborate and plan for difficult operative cases. Live streaming of video has allowed for intraoperative telementoring. Finally, postoperative use of video has provided structure for peer coaching to evaluate and improve surgical skill. Applying these approaches into practice is becoming easier as most of our surgical platforms (e.g., laparoscopic, and endoscopy) now have video recording technology built in and video editing software has become more user friendly. Future applications of video technology are being developed, including possible integration into accreditation and board certification.

Documentation of surgical specimens using digital video technology.

Digital technology is commonly used for documentation of specimens in anatomic pathology and has been mainly limited to still photographs. Technologic innovations, such as digital video, provide additional, in some cases better, options for documentation. To demonstrate the applicability of digital video to the documentation of surgical specimens. A Canon Elura MC40 digital camcorder was used, and the unedited movies were transferred to a Macintosh PowerBook G4 computer. Both the camcorder and specimens were hand-held during filming. The movies were edited using the software iMovie. Annotations and histologic photographs may be easily incorporated into movies when editing, if desired. The finished movies are best viewed in computers which contain the free program QuickTime Player. Movies may also be incorporated onto DVDs, for viewing in standard DVD players or appropriately equipped computers. The final movies are on average 2 minutes in duration, with a file size between 2 and 400 megabytes, depending on the intended use. Because of file size, distribution is more practical via CD or DVD, but movies may be compressed for distribution through the Internet (e-mail, Web sites) or through internal hospital networks. Digital video is a practical, easy, and affordable methodology for specimen documentation, permitting a better 3-dimensional understanding of the specimens. Discussions with colleagues, student education, presentation at conferences, and other educational activities can be enhanced with the implementation of digital video technology.

In 2009, the Great Lakes Native American Research Center for Health (GLNARCH) set out to generate a promotional video that highlights the successes of the program. Ten GLNARCH interns were interviewed and filmed for participation in the promotional video using a documentary production style. During the editing and transcription process, interviewer responses were noted for relevance to theoretical frameworks--specifically, tribal critical race theory, mentoring, and cultural compatibility--which guided GLNARCH program design. Quotations were transcribed to illustrate these themes. Though the interviews were not intended as a formal qualitative analysis, powerful narratives that are relevant to participatory research emerged. The emergence of narratives that align with relevant theoretical frameworks suggests a novel methodology for a culturally responsive, participatory reporting system.

A design for living technology: experiments with the mind time machine.

PubMed

Ikegami, Takashi

2013-01-01

Living technology aims to help people expand their experiences in everyday life. The environment offers people ways to interact with it, which we call affordances. Living technology is a design for new affordances. When we experience something new, we remember it by the way we perceive and interact with it. Recent studies in neuroscience have led to the idea of a default mode network, which is a baseline activity of a brain system. The autonomy of artificial life must be understood as a sort of default mode that self-organizes its baseline activity, preparing for its external inputs and its interaction with humans. I thus propose a method for creating a suitable default mode as a design principle for living technology. I built a machine called the mind time machine (MTM), which runs continuously for 10 h per day and receives visual data from its environment using 15 video cameras. The MTM receives and edits the video inputs while it self-organizes the momentary now. Its base program is a neural network that includes chaotic dynamics inside the system and a meta-network that consists of video feedback systems. Using this system as the hardware and a default mode network as a conceptual framework, I describe the system's autonomous behavior. Using the MTM as a testing ground, I propose a design principle for living technology.

Video Game Playing Effects on Obesity in an Adolescent with Autism Spectrum Disorder: A Case Study.

2015-01-01

Adolescent obesity has tripled in the past two decades, and adolescents with disabilities, specifically autism spectrum disorders (ASD), may be at greater risk for obesity due to the behavioral, physical, and psychosocial complications related to their disorder. This case study reports the effects of video game playing on an obese adolescent with ASD and illustrates the use of a multiple baseline single subject design. Over 12 weeks, the participant played inactive (6 weeks) and active video games (6 weeks) on the Wii console. Physiological data were evaluated weekly at home. Stress and anxiety were measured via the Stress Survey Schedule for Individuals with Autism and Other Pervasive Non-Developmental Disorders (SSS) and the Behavior Assessment System for Children Second Edition (BASC-2) pre- and postintervention. The Therapy Attitude Inventory (TAI) was used to determine parental perception of video game playing as a socially valid intervention to reduce stress and anxiety. Results demonstrated that active video game playing slowed and/or reduced weight and BMI with minimal changes to waist-to-hip ratios, triceps skinfolds, and stress and anxiety. This study demonstrates how alternative methods for physical activity may be used to improve health outcomes of overweight/obese adolescents with ASD and suggests directions for future research.

Abstract Video game addiction or Internet game disorder, as proposed by the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), has similar criterion characteristics to other impulse control disorders. There is limited research examining video game addiction within a behavioral economic framework using delay discounting. The current study evaluated delay-discounting patterns of money and video game play by usual weekly hours of video game play. A total of 104 participants were split into 1 of 3 groups of video game players (low, medium, and high) and were asked to complete a monetary and video game discounting procedure through an online survey. Results showed significant differences between groups within both the monetary (p = 0.003) and video game discounting procedures (p = 0.004). Additionally, a positive linear relationship was noted between the groups across both procedures. The results of the current article reinforce previous findings that more hours of video game use are associated with greater impulsivity and provide implications for future research. PMID:28118044

Patch-based image synthesis methods have been successfully applied for various editing tasks on still images, videos and stereo pairs. In this work we extend patch-based synthesis to plenoptic images captured by consumer-level lenselet-based devices for interactive, efficient light field editing. In our method the light field is represented as a set of images captured from different viewpoints. We decompose the central view into different depth layers, and present it to the user for specifying the editing goals. Given an editing task, our method performs patch-based image synthesis on all affected layers of the central view, and then propagates the edits to all other views. Interaction is done through a conventional 2D image editing user interface that is familiar to novice users. Our method correctly handles object boundary occlusion with semi-transparency, thus can generate more realistic results than previous methods. We demonstrate compelling results on a wide range of applications such as hole-filling, object reshuffling and resizing, changing object depth, light field upscaling and parallax magnification.

Portable video technology is a widely available new tool with potential to be used by pediatric otolaryngology practices for patient and family education. Podcasts are media broadcasts that employ this new technology. They can be accessed via the Internet and viewed either on a personal computer or on a handheld device, such as an iPod or an MP3 player. We wished to examine the feasibility of establishing a podcast-hosting Web site. We digitally recorded pediatric otologic procedures in the operating room and saved the digital files to DVDs. We then edited the DVDs at home with video-editing software on a personal computer. Next, spoken narrative was recorded with audio-recording software and combined with the edited video clips. The final products were converted into the M4V file format, and the final versions were uploaded onto our hospital's Web site. We then downloaded the podcasts onto a high-quality portable media player so that we could evaluate their quality. All of the podcasts are now on the hospital Web site, where they can be downloaded by patients and families at no cost. The site includes instructions on how to download the appropriate free software for viewing the podcasts on a portable media player or on a computer. Using this technology for patient education expands the audience and permits portability of information. We conclude that a home computer can be used to inexpensively create informative surgery demonstrations that can be accessed via a Web site and transferred to portable viewing devices with excellent quality.

The main goal of this work is enhanced the student`s self-learning in subjects regarding irrigation and its technology. Thus, the use of visual media (video recording) during the lectures (master classes and practicum) will help the students in understanding the scope of the course since they can watch the recorded material at any time and as many times they wish. The study comprised two parts. In the first, lectures were video filmed inside the classroom during one semester (16 weeks and four hours per week) in the course "Irrigation Systems and Technology" which is taught at the Technical University of Madrid. In total, 200 videos, approximated 12 min long, were recorded. Since the You tube platform is a worldwide platform and since it is commonly used by students and professors, the videos were uploaded in it. Then, the URL was inserted in the Moodle platform which contains the materials for the course. In the second part, the videos were edited and formatted. Special care was taking to maintain image and audio quality. Finally, thirty videos were developed which focused on the different main areas of the course and containing a clear and brief explanation of their basis. Each video lasted between 30 and 45 min Finally, a survey was handled at the end of the semester in order to assess the students' opinion about the methodology. In the questionnaire, the students highlighted the key aspects during the learning process and in general, they were very satisfied with the methodology.

The method used is a descriptive analysis of existing computer- and video games that have been adapted for stereoscopic display using semi-automatic rendering techniques (e.g. Nvidia 3D Vision) or games which have been specifically designed for stereoscopic vision. Digital games often feature compelling visual interfaces that combine high usability with creative visual design. We explore selected examples of game interfaces in stereoscopic vision regarding their stereoscopic characteristics, how they draw attention, how we judge effect and comfort and where the interfaces fail. As a result, we propose a list of five aspects which should be considered when designing stereoscopic visual information: explicit information, implicit information, spatial reference, drawing attention, and vertical alignment. We discuss possible consequences, opportunities and challenges for integrating visual information elements into 3D-TV content. This work shall further help to improve current editing systems and identifies a need for future editing systems for 3DTV, e.g., live editing and real-time alignment of visual information into 3D footage.

Science on TeacherTube: A Mixed Methods Analysis of Teacher Produced Video

NASA Astrophysics Data System (ADS)

Chmiel, Margaret (Marjee)

Increased bandwidth, inexpensive video cameras and easy-to-use video editing software have made social media sites featuring user generated video (UGV) an increasingly popular vehicle for online communication. As such, UGV have come to play a role in education, both formal and informal, but there has been little research on this topic in scholarly literature. In this mixed-methods study, a content and discourse analysis are used to describe the most successful UGV in the science channel of an education-focused site called TeacherTube. The analysis finds that state achievement tests, and their focus on vocabulary and recall-level knowledge, drive much of the content found on TeacherTube.

Extensions under development for the HEVC standard

Sullivan, Gary J.

2013-09-01

This paper discusses standardization activities for extending the capabilities of the High Efficiency Video Coding (HEVC) standard - the first edition of which was completed in early 2013. These near-term extensions are focused on three areas: range extensions (such as enhanced chroma formats, monochrome video, and increased bit depth), bitstream scalability extensions for spatial and fidelity scalability, and 3D video extensions (including stereoscopic/multi-view coding, and probably also depth map coding and combinations thereof). Standardization extensions on each of these topics will be completed by mid-2014, and further work beyond that timeframe is also discussed.

DICOM to print, 35-mm slides, web, and video projector: tutorial using Adobe Photoshop.

PubMed

Gurney, Jud W

2002-10-01

Preparing images for publication has dealt with film and the photographic process. With picture archiving and communications systems, many departments will no longer produce film. This will change how images are produced for publication. DICOM, the file format for radiographic images, has to be converted and then prepared for traditional publication, 35-mm slides, the newest techniques of video projection, and the World Wide Web. Tagged image file format is the common format for traditional print publication, whereas joint photographic expert group is the current file format for the World Wide Web. Each medium has specific requirements that can be met with a common image-editing program such as Adobe Photoshop (Adobe Systems, San Jose, CA). High-resolution images are required for print, a process that requires interpolation. However, the Internet requires images with a small file size for rapid transmission. The resolution of each output differs and the image resolution must be optimized to match the output of the publishing medium.

To determine impacts on social-emotional development at school entry of a pediatric primary care intervention (Video Interaction Project [VIP]) promoting positive parenting through reading aloud and play, delivered in 2 phases: infant through toddler (VIP birth to 3 years [VIP 0-3]) and preschool-age (VIP 3 to 5 years [VIP 3-5]). Factorial randomized controlled trial with postpartum enrollment and random assignment to VIP 0-3, control 0 to 3 years, and a third group without school entry follow-up (Building Blocks) and 3-year second random assignment of VIP 0-3 and control 0 to 3 years to VIP 3-5 or control 3 to 5 years. In the VIP, a bilingual facilitator video recorded the parent and child reading and/or playing using provided learning materials and reviewed videos to reinforce positive interactions. Social-emotional development at 4.5 years was assessed by parent-report Behavior Assessment System for Children, Second Edition (Social Skills, Attention Problems, Hyperactivity, Aggression, Externalizing Problems). VIP 0-3 and VIP 3-5 were independently associated with improved 4.5-year Behavior Assessment System for Children, Second Edition T-scores, with effect sizes (Cohen's d) ∼-0.25 to -0.30. Receipt of combined VIP 0-3 and VIP 3-5 was associated with d = -0.63 reduction in Hyperactivity ( P = .001). VIP 0-3 resulted in reduced "Clinically Significant" Hyperactivity (relative risk reduction for overall sample: 69.2%; P = .03; relative risk reduction for increased psychosocial risk: 100%; P = .006). Multilevel models revealed significant VIP 0-3 linear effects and age × VIP 3-5 interactions. Phase VIP 0-3 resulted in sustained impacts on behavior problems 1.5 years after program completion. VIP 3-5 had additional, independent impacts. With our findings, we support the use of pediatric primary care to promote reading aloud and play from birth to 5 years, and the potential for such programs to enhance social-emotional development.

Experiences of citizen-based reporting of rainfall events using lab-generated videos

NASA Astrophysics Data System (ADS)

Alfonso, Leonardo; Chacon, Juan

2016-04-01

Hydrologic studies rely on the availability of good-quality precipitation estimates. However, in remote areas of the world and particularly in developing countries, ground-based measurement networks are either sparse or nonexistent. This creates difficulties in the estimation of precipitation, which limits the development of hydrologic forecasting and early warning systems for these regions. The EC-FP7 WeSenseIt project aims at exploring the involvement of citizens in the observation of the water cycle with innovative sensor technologies, including mobile telephony. In particular, the project explores the use of a smartphone applications to facilitate the reporting water-related situations. Apart from the challenge of using such information for scientific purposes, the citizen engagement is one of the most important issues to address. To this end effortless methods for reporting need to be developed in order to involve as many people as possible in these experiments. A potential solution to overcome these drawbacks, consisting on lab-controlled rainfall videos have been produced to help mapping the extent and distribution of rainfall fields with minimum effort [1]. In addition, the quality of the collected rainfall information has also been studied [2] by means of different experiments with students. The present research shows the latest results of the application of this method and evaluates the experiences in some cases. [1] Alfonso, L., J. Chacón, and G.

Galiano, Vicente; López-Granado, Otoniel; Malumbres, Manuel P.; Migallón, Hector

2013-12-01

Three-dimensional wavelet transform (3D-DWT) encoders are good candidates for applications like professional video editing, video surveillance, multi-spectral satellite imaging, etc. where a frame must be reconstructed as quickly as possible. In this paper, we present a new 3D-DWT video encoder based on a fast run-length coding engine. Furthermore, we present several multicore optimizations to speed-up the 3D-DWT computation. An exhaustive evaluation of the proposed encoder (3D-GOP-RL) has been performed, and we have compared the evaluation results with other video encoders in terms of rate/distortion (R/D), coding/decoding delay, and memory consumption. Results show that the proposed encoder obtains good R/D results for high-resolution video sequences with nearly in-place computation using only the memory needed to store a group of pictures. After applying the multicore optimization strategies over the 3D DWT, the proposed encoder is able to compress a full high-definition video sequence in real-time.

The new NFL Films 200,000 sq. ft. headquarters is home for the critically acclaimed film production that preserves the NFL's visual legacy week-to-week during the football season, and is also the technical plant that processes and archives football footage from the earliest recorded media to the current network broadcasts. No other company in the country shoots more film than NFL Films, and the inclusion of cutting-edge video and audio formats demands that their technical spaces continually integrate the latest in the ever-changing world of technology. This facility houses a staggering array of acoustically sensitive spaces where music and sound are equal partners with the visual medium. Over 90,000 sq. ft. of sound critical technical space is comprised of an array of sound stages, music scoring stages, audio control rooms, music writing rooms, recording studios, mixing theaters, video production control rooms, editing suites, and a screening theater. Every production control space in the building is designed to monitor and produce multi channel surround sound audio. An overview of the architectural and acoustical design challenges encountered for each sophisticated listening, recording, viewing, editing, and sound critical environment will be discussed.

Reliability of trauma management videos on YouTube and their compliance with ATLS® (9th edition) guideline.

Şaşmaz, M I; Akça, A H

2017-06-01

In this study, the reliability of trauma management scenario videos (in English) on YouTube and their compliance with Advanced Trauma Life Support (ATLS ® ) guidelines were investigated. The search was conducted on February 15, 2016 by using the terms "assessment of trauma" and ''management of trauma''. All videos that were uploaded between January 2011 and June 2016 were viewed by two experienced emergency physicians. The data regarding the date of upload, the type of the uploader, duration of the video and view counts were recorded. The videos were categorized according to the video source and scores. The search results yielded 880 videos. Eight hundred and thirteen videos were excluded by the researchers. The distribution of videos by years was found to be balanced. The scores of videos uploaded by an institution were determined to be higher compared to other groups (p = 0.003). The findings of this study display that trauma management videos on YouTube in the majority of cases are not reliable/compliant with ATLS-guidelines and can therefore not be recommended for educational purposes. These data may only be used in public education after making necessary arrangements.

Do you use video in your teaching? Do you make your own video? Interested in joining our growing community of geoscience educators designing and using video inside and outside the classroom? Over four months in Spring 2014, 22 educators of varying video design and development expertise participated in an NSF-funded On the Cutting Edge virtual workshop to review the best educational research on video design and use; to share video-development/use strategies and experiences; and to develop a website of resources for a growing community of geoscience educators who use video: http://serc.carleton.edu/NAGTWorkshops/video/workshop2014/index.html. The site includes links to workshop presentations, teaching activity collections, and a growing collection of online video resources, including "How-To" videos for various video editing or video-making software and hardware options. Additional web resources support several topical themes including: using videos to flip classes, handling ADA access and copyright issues, assessing the effectiveness of videos inside and outside the classroom, best design principles for video learning, and lists and links of the best videos publicly available for use. The workshop represents an initial step in the creation of an informal team of collaborators devoted to the development and support of an ongoing network of geoscience educators designing and using video. Instructors who are interested in joining this effort are encouraged to contact the lead author.

The aim of this study was to test two different video cameras and recording systems used in thyroid surgery in our Department. This is meant to be an attempt to record the real point of view of the magnified vision of surgeon, so as to make the viewer aware of the difference with the naked eye vision. In this retrospective study, we recorded and compared twenty thyroidectomies performed using loupes magnification and microsurgical technique: ten were recorded with GoPro ® 4 Session action cam (commercially available) and ten with our new prototype of head mounted video camera. Settings were selected before surgery for both cameras. The recording time is about from 1 to 2 h for GoPro ® and from 3 to 5 h for our prototype. The average time of preparation to fit the camera on the surgeon's head and set the functionality is about 5 min for GoPro ® and 7-8 min for the prototype, mostly due to HDMI wiring cable. Videos recorded with the prototype require no further editing, which is mandatory for videos recorded with GoPro ® to highlight the surgical details. the present study showed that our prototype of video camera, compared with GoPro ® 4 Session, guarantees best results in terms of surgical video recording quality, provides to the viewer the exact perspective of the microsurgeon and shows accurately his magnified view through the loupes in thyroid surgery. These recordings are surgical aids for teaching and education and might be a method of self-analysis of surgical technique. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

Purpose: The purpose of this study is to describe the use of commercial digital single light reflex (DSLR) for vitreoretinal surgery recording and compare it to standard 3-chip charged coupling device (CCD) camera. Methods: Simultaneous recording was done using Sony A7s2 camera and Sony high-definition 3-chip camera attached to each side of the microscope. The videos recorded from both the camera systems were edited and sequences of similar time frames were selected. Three sequences that selected for evaluation were (a) anterior segment surgery, (b) surgery under direct viewing system, and (c) surgery under indirect wide-angle viewing system. The videos of each sequence were evaluated and rated on a scale of 0-10 for color, contrast, and overall quality Results: Most results were rated either 8/10 or 9/10 for both the cameras. A noninferiority analysis by comparing mean scores of DSLR camera versus CCD camera was performed and P values were obtained. The mean scores of the two cameras were comparable for each other on all parameters assessed in the different videos except of color and contrast in posterior pole view and color on wide-angle view, which were rated significantly higher (better) in DSLR camera. Conclusion: Commercial DSLRs are an affordable low-cost alternative for vitreoretinal surgery recording and may be used for documentation and teaching. PMID:29283133

2018-01-01

Considering how many people obtain information about their health online, the aim of this study was to describe the content of the currently most widely viewed YouTube videos related to concussions and to test the hypothesis that consumer videos would be anecdotal, while other sources would be more informational. The term "concussion" was used to search for videos with 100,000 or more views on YouTube that were posted in English or Spanish. Descriptive information about each video was recorded, as was information on whether certain content was conveyed during the video. The main outcome measures are sources of upload and content of videos. Consumer videos accounted for 48% of the videos, television based accounted for 50% of the videos, and internet based accounted for only 2% of the videos. None of the videos viewed fell into the professional category. Television based videos were viewed significantly more than consumer or internet based videos. Consumer and television based videos were equally anecdotal. Many of the videos focused on adolescents and were related to sports injuries. The majority of the videos (70.4%) addressed concussion causes, with 48% stating sports. Few videos discussed symptoms of concussion and prevention. The potential for widespread misinformation necessitates caution when obtaining information on concussion on a freely accessible and editable medium, such as YouTube.

The aim of this study was to examine observer reliability of the Gross Motor Performance Measure (GMPM) and the Quality of Upper Extremity Skills Test (QUEST) based on video clips. The tests were administered to 26 children with cerebral palsy (CP; 14 males, 12 females; range 2-13y, mean 7y 6mo), 24 with spastic CP, and two with dyskinesia. Respectively, five, six, five, four, and six children were classified in Gross Motor Function Classification System Levels I to V; and four, nine, five, five, and three children were classified in Manual Ability Classification System levels I to V. The children's performances were recorded and edited. Two experienced paediatric physical therapists assessed the children from watching the video clips. Intraobserver and interobserver reliability values of the total scores were mostly high, intraclass correlation coefficient (ICC)(1,1) varying from 0.69 to 0.97 with only one coefficient below 0.89. The ICCs of subscores varied from 0.36 to 0.95, finding'Alignment'and'Weight shift'in GMPM and'Protective extension'in QUEST highly reliable. The subscores'Dissociated movements'in GMPM and QUEST, and'Grasp'in QUEST were the least reliable, and recommendations are made to increase reliability of these subscores. Video scoring was time consuming, but was found to offer many advantages; the possibility to review performance, to use special trained observers for scoring and less demanding assessment for the children.

Feedforward Self-Modeling Enhances Skill Acquisition in Children Learning Trampoline Skills

2011-01-01

The purpose of this research was to examine whether children would benefit from a feedforward self-modeling (FSM) video and to explore possible explanatory mechanisms for the potential benefits, using a self-regulation framework. To this end, children were involved in learning two five-skill trampoline routines. For one of the routines, a FSM video was provided during acquisition, whereas only verbal instructions were provided for the alternate routine. The FSM involved editing video footage such that it showed the learner performing the trampoline routine at a higher skill level than their current capability. Analyses of the data showed that while physical performance benefits were observed for the routine that was learned with the FSM video, no differences were obtained in relation to the self-regulatory measures. Thus, the FSM video enhanced motor skill acquisition, but this could not be explained by changes to the varied self-regulatory processes examined. PMID:21779270

Hamasaki, Masahiro; Takeda, Hideaki; Nishimura, Takuichi

The Web technology enables numerous people to collaborate in creation. We designate it as massively collaborative creation via the Web. As an example of massively collaborative creation, we particularly examine video development on Nico Nico Douga, which is a video sharing website that is popular in Japan. We specifically examine videos on Hatsune Miku, a version of a singing synthesizer application software that has inspired not only song creation but also songwriting, illustration, and video editing. As described herein, creators of interact to create new contents through their social network. In this paper, we analyzed the process of developing thousands of videos based on creators' social networks and investigate relationships among creation activity and social networks. The social network reveals interesting features. Creators generate large and sparse social networks including some centralized communities, and such centralized community's members shared special tags. Different categories of creators have different roles in evolving the network, e.g., songwriters gather more links than other categories, implying that they are triggers to network evolution.

An Internet-based method is described for submission of video clips to a website editor to be reviewed, edited, and then uploaded onto a video server, with a hypertext link to a website. The information on the webpages is searchable via the website sitemap on Internet search engines. A survey of video users who accessed a single 59-minute FNA cytology training cytology video via the website showed a mean score for usefulness for specialists/consultants of 3.75, range 1-5, n = 16, usefulness for trainees mean score was 4.4, range 3-5, n = 12, with a mean score for visual and sound quality of 3.9, range 2-5, n = 16. Fifteen out of 17 respondents thought that posting video training material on the Internet was a good idea, and 9 of 17 respondents would also consider submitting training videos to a similar website. This brief exercise has shown that there is value in posting educational or training video content on the Internet and that the use of streamed video accessed via the Internet will be of increasing importance.

Data videos, or short data-driven motion graphics, are an increasingly popular medium for storytelling. However, creating data videos is difficult as it involves pulling together a unique combination of skills. We introduce DataClips, an authoring tool aimed at lowering the barriers to crafting data videos. DataClips allows non-experts to assemble data-driven "clips" together to form longer sequences. We constructed the library of data clips by analyzing the composition of over 70 data videos produced by reputable sources such as The New York Times and The Guardian. We demonstrate that DataClips can reproduce over 90% of our data videos corpus. We also report on a qualitative study comparing the authoring process and outcome achieved by (1) non-experts using DataClips, and (2) experts using Adobe Illustrator and After Effects to create data-driven clips. Results indicated that non-experts are able to learn and use DataClips with a short training period. In the span of one hour, they were able to produce more videos than experts using a professional editing tool, and their clips were rated similarly by an independent audience.

[Purpose] The purpose of this study was to investigate reliability of the test of gross motor development second edition (TGMD-2) for Kindergarten children in Myanmar. [Subjects and Methods] Fifty healthy Kindergarten children (23 males, 27 females) whose parents/guardians had given written consent were participated. The subjects were explained and demonstrated all 12 gross motor skills of TGMD-2 before the assessment. Each subject individually performed two trials for each gross motor skill and the performance was video recorded. Three raters separately watched the video recordings and rated for inter-rater reliability. The second assessment was done one month later with 25 out of 50 subjects for test-rest reliability. The video recordings of 12 subjects were randomly selected from the first 50 recordings for intra-rater reliability six weeks after the first assessment. The agreement on the locomotor and object control raw scores and the gross motor quotient (GMQ) were calculated. [Results] The findings of all the reliability coefficients for the locomotor and object control raw scores and the GMQ were interpreted as good and excellent reliability. [Conclusion] The results represented that TGMD-2 is a highly reliable and appropriate assessment tool for assessing gross motor skill development of Kindergarten children in Myanmar. PMID:29184278

Tolerton, Sarah K; Hugh, Thomas J; Cosman, Peter H

2012-01-01

Audiovisual learning resources have become valuable adjuncts to formal teaching in surgical training. This report discusses the process and challenges of preparing an audiovisual teaching tool for laparoscopic cholecystectomy. The relative value in surgical education and training, for both the creator and viewer are addressed. This audiovisual teaching resource was prepared as part of the Master of Surgery program at the University of Sydney, Australia. The different methods of video production used to create operative teaching tools are discussed. Collating and editing material for an audiovisual teaching resource can be a time-consuming and technically challenging process. However, quality learning resources can now be produced even with limited prior video editing experience. With minimal cost and suitable guidance to ensure clinically relevant content, most surgeons should be able to produce short, high-quality education videos of both open and minimally invasive surgery. Despite the challenges faced during production of audiovisual teaching tools, these resources are now relatively easy to produce using readily available software. These resources are particularly attractive to surgical trainees when real time operative footage is used. They serve as valuable adjuncts to formal teaching, particularly in the setting of minimally invasive surgery. Copyright © 2012 Association of Program Directors in Surgery. Published by Elsevier Inc.

Salvia divinorum: effects and use among YouTube users.

PubMed

Lange, James E; Daniel, Jason; Homer, Kestrel; Reed, Mark B; Clapp, John D

2010-04-01

Salvia divinorum (salvia) is an intense, short-acting hallucinogenic plant gaining popularity among adolescents in the United States. There has been little scientific documentation of salvia's effects. The popular video-sharing website YouTube has received literally thousands of video-posts of people using salvia. The objective of this study was to assess the effects of salvia use through systematic observations of YouTube videos. A sample of salvia videos was obtained using the search term "salvia." The videos were further screened and only videos that captured the entire drug "trip" without video edits were included in the analyses described here (n=34). Three trained research assistants independently watched the videos and rated their observations on 42 effects in 30-s intervals. Onset of symptoms was quick (often less than 30s) and tended to dissipate within 8min. Further, there was a relationship between salvia dose and effect duration. Since salvia's effects on humans are largely undocumented, this study provides the look at users in a non-laboratory environment (e.g. self-taped videos) exhibiting impairments and behaviors consistent with this powerful hallucinogen. Also, this study demonstrates the feasibility and shortcomings of using YouTube videos to assess emerging drugs and drug effects. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

Knowledge Interaction Design for Creative Knowledge Work

NASA Astrophysics Data System (ADS)

Nakakoji, Kumiyo; Yamamoto, Yasuhiro

This paper describes our approach for the development of application systems for creative knowledge work, particularly for early stages of information design tasks. Being a cognitive tool serving as a means of externalization, an application system affects how the user is engaged in the creative process through its visual interaction design. Knowledge interaction design described in this paper is a framework where a set of application systems for different information design domains are developed based on an interaction model, which is designed for a particular model of a thinking process. We have developed two sets of application systems using the knowledge interaction design framework: one includes systems for linear information design, such as writing, movie-editing, and video-analysis; the other includes systems for network information design, such as file-system navigation and hypertext authoring. Our experience shows that the resulting systems encourage users to follow a certain cognitive path through graceful user experience.

Common and Innovative Visuals: A sparsity modeling framework for video.

PubMed

Abdolhosseini Moghadam, Abdolreza; Kumar, Mrityunjay; Radha, Hayder

2014-05-02

Efficient video representation models are critical for many video analysis and processing tasks. In this paper, we present a framework based on the concept of finding the sparsest solution to model video frames. To model the spatio-temporal information, frames from one scene are decomposed into two components: (i) a common frame, which describes the visual information common to all the frames in the scene/segment, and (ii) a set of innovative frames, which depicts the dynamic behaviour of the scene. The proposed approach exploits and builds on recent results in the field of compressed sensing to jointly estimate the common frame and the innovative frames for each video segment. We refer to the proposed modeling framework by CIV (Common and Innovative Visuals). We show how the proposed model can be utilized to find scene change boundaries and extend CIV to videos from multiple scenes. Furthermore, the proposed model is robust to noise and can be used for various video processing applications without relying on motion estimation and detection or image segmentation. Results for object tracking, video editing (object removal, inpainting) and scene change detection are presented to demonstrate the efficiency and the performance of the proposed model.

Generation of animation sequences of three dimensional models

NASA Technical Reports Server (NTRS)

Poi, Sharon (Inventor); Bell, Brad N. (Inventor)

1990-01-01

The invention is directed toward a method and apparatus for generating an animated sequence through the movement of three-dimensional graphical models. A plurality of pre-defined graphical models are stored and manipulated in response to interactive commands or by means of a pre-defined command file. The models may be combined as part of a hierarchical structure to represent physical systems without need to create a separate model which represents the combined system. System motion is simulated through the introduction of translation, rotation and scaling parameters upon a model within the system. The motion is then transmitted down through the system hierarchy of models in accordance with hierarchical definitions and joint movement limitations. The present invention also calls for a method of editing hierarchical structure in response to interactive commands or a command file such that a model may be included, deleted, copied or moved within multiple system model hierarchies. The present invention also calls for the definition of multiple viewpoints or cameras which may exist as part of a system hierarchy or as an independent camera. The simulated movement of the models and systems is graphically displayed on a monitor and a frame is recorded by means of a video controller. Multiple movement and hierarchy manipulations are then recorded as a sequence of frames which may be played back as an animation sequence on a video cassette recorder.

Red blood cell sedimentation of Apheresis Granulocytes.

Lodermeier, Michelle A; Byrne, Karen M; Flegel, Willy A

2017-10-01

Sedimentation of Apheresis Granulocyte components removes red blood cells. It is used to increase the blood donor pool when blood group-compatible donors cannot be recruited for a patient because of a major ABO incompatibility or incompatible red blood cell antibodies in the recipient. Because granulocytes have little ABO and few other red blood cell antigens on their membrane, such incompatibility lies mostly with the contaminating red blood cells. Video Clip S1 shows the process of red blood cell sedimentation of an Apheresis Granulocyte component. This video was filmed with a single smart phone attached to a commercial tripod and was edited on a tablet computer with free software by an amateur videographer without prior video experience. © 2017 AABB.

Moderating factors of video-modeling with other as model: a meta-analysis of single-case studies.

PubMed

Mason, Rose A; Ganz, Jennifer B; Parker, Richard I; Burke, Mack D; Camargo, Siglia P

2012-01-01

Video modeling with other as model (VMO) is a more practical method for implementing video-based modeling techniques, such as video self-modeling, which requires significantly more editing. Despite this, identification of contextual factors such as participant characteristics and targeted outcomes that moderate the effectiveness of VMO has not previously been explored. The purpose of this study was to meta-analytically evaluate the evidence base of VMO with individuals with disabilities to determine if participant characteristics and targeted outcomes moderate the effectiveness of the intervention. Findings indicate that VMO is highly effective for participants with autism spectrum disorder (IRD=.83) and moderately effective for participants with developmental disabilities (IRD=.68). However, differential effects are indicated across levels of moderators for diagnoses and targeted outcomes. Implications for practice and future research are discussed.

A study on multiresolution lossless video coding using inter/intra frame adaptive prediction

NASA Astrophysics Data System (ADS)

Nakachi, Takayuki; Sawabe, Tomoko; Fujii, Tetsuro

2003-06-01

Lossless video coding is required in the fields of archiving and editing digital cinema or digital broadcasting contents. This paper combines a discrete wavelet transform and adaptive inter/intra-frame prediction in the wavelet transform domain to create multiresolution lossless video coding. The multiresolution structure offered by the wavelet transform facilitates interchange among several video source formats such as Super High Definition (SHD) images, HDTV, SDTV, and mobile applications. Adaptive inter/intra-frame prediction is an extension of JPEG-LS, a state-of-the-art lossless still image compression standard. Based on the image statistics of the wavelet transform domains in successive frames, inter/intra frame adaptive prediction is applied to the appropriate wavelet transform domain. This adaptation offers superior compression performance. This is achieved with low computational cost and no increase in additional information. Experiments on digital cinema test sequences confirm the effectiveness of the proposed algorithm.

Integrative, Interdisciplinary Learning in Bermuda Through Video Projects

NASA Astrophysics Data System (ADS)

Fox, R. J.; Connaughton, M.

2017-12-01

Understanding an ecosystem and how humans impact it requires a multidisciplinary perspective and immersive, experiential learning is an exceptional way to achieve understanding. In summer 2017 we took 18 students to the Bermuda Institute of Ocean Sciences (BIOS) as part of a Washington College two-week, four-credit summer field course. We took a multi-disciplinary approach in choosing the curriculum. We focused on the ecology of the islands and surrounding coral reefs as well as the environmental impacts humans are having on the islands. Additionally, we included geology and both local and natural history. Our teaching was supplemented by the BIOS staff and local tour guides. The student learning was integrated and reinforced through student-led video projects. Groups of three students were tasked with creating a 5-7 minute video appropriate for a public audience. We selected video topics based upon locations we would visit in the first week and topics were randomly assigned. The project intention was for the students to critically analyze and evaluate an area of Bermuda that is a worthwhile tourist destination. Students presented why a tourist should visit a locale, the area's ecological distinctiveness and complexity, the impact humans are having, and ways tourists can foster stewardship of that locale. These projects required students to learn how to make and edit videos, collaborate with peers, communicate a narrative to the public, integrate multi-disciplinary topics for a clear, whole-system perspective, observe the environment from a critical viewpoint, and interview local experts. The students produced the videos within the two-week period, and we viewed the videos as a group on the last day. The students worked hard, were proud of their final products, and produced excellent videos. They enjoyed the process, which provided them opportunities to collaborate, show individual strengths, be creative, and work independently of the instructors.

Object detection in cinematographic video sequences for automatic indexing

NASA Astrophysics Data System (ADS)

Stauder, Jurgen; Chupeau, Bertrand; Oisel, Lionel

2003-06-01

This paper presents an object detection framework applied to cinematographic post-processing of video sequences. Post-processing is done after production and before editing. At the beginning of each shot of a video, a slate (also called clapperboard) is shown. The slate contains notably an electronic audio timecode that is necessary for audio-visual synchronization. This paper presents an object detection framework to detect slates in video sequences for automatic indexing and post-processing. It is based on five steps. The first two steps aim to reduce drastically the video data to be analyzed. They ensure high recall rate but have low precision. The first step detects images at the beginning of a shot possibly showing up a slate while the second step searches in these images for candidates regions with color distribution similar to slates. The objective is to not miss any slate while eliminating long parts of video without slate appearance. The third and fourth steps are statistical classification and pattern matching to detected and precisely locate slates in candidate regions. These steps ensure high recall rate and high precision. The objective is to detect slates with very little false alarms to minimize interactive corrections. In a last step, electronic timecodes are read from slates to automize audio-visual synchronization. The presented slate detector has a recall rate of 89% and a precision of 97,5%. By temporal integration, much more than 89% of shots in dailies are detected. By timecode coherence analysis, the precision can be raised too. Issues for future work are to accelerate the system to be faster than real-time and to extend the framework for several slate types.

Background: Hamilton depression rating scale (Ham-D) is the most widely used clinician rating scale for depression. There has been no Indian study that has examined the inter-rater reliability (IRR) of video-recorded interviews of the 21-item Ham-D. Aim: To study the IRR of scoring video-recorded interviews for 21-item Ham-D. Materials and Methods: Eighteen subjects with major depressive disorder involved in a larger study were interviewed using the semi-structured clinical interview of the 21-item Ham-D by a primary rater after informed consent. These interviews were video-recorded and portions edited to ensure rater blinding. Subsequently, the video-recorded interviews were rated by a “blind” rater. Both rated the different sub-domains of Ham-D according to Rhoades and Overall (1983). IRR was evaluated using intra-class correlation coefficient. Results: Excellent IRR was observed (0.9891) between the two raters. This was true for each of the primary factors and super-factors. Conclusion: Video recorded 21-item Ham-D has excellentIRR. Video-recorded interviews of Ham-D can be reliably used to blind raters in research. PMID:19881046

Learning About Energy Resources Through Student Created Video Documentaries in the University Science Classroom

NASA Astrophysics Data System (ADS)

Wade, P.; Courtney, A.

2010-12-01

Students enrolled in an undergraduate non-science majors’ Energy Perspectives course created 10-15 minute video documentaries on topics related to Energy Resources and the Environment. Video project topics included wave, biodiesel, clean coal, hydro, solar and “off-the-grid” energy technologies. No student had any prior experience with creating video projects. Students had Liberal Arts academic backgrounds that included Anthropology, Theater Arts, International Studies, English and Early Childhood Education. Students were required to: 1) select a topic, 2) conduct research, 3) write a narrative, 4) construct a project storyboard, 5) shoot or acquire video and photos (from legal sources), 6) record the narrative, and 7) construct the video documentary. This study describes the instructional approach of using student created video documentaries as projects in an undergraduate non-science majors’ science course. Two knowledge survey instruments were used for assessment purposes. Each instrument was administered Pre-, Mid- and Post course. One survey focused on the skills necessary to research and produce video documentaries. Results showed students acquired enhanced technology skills especially with regard to research techniques, writing skills and video editing. The second survey assessed students’ content knowledge acquired from each documentary. Results indicated students’ increased their content knowledge of energy resource topics. Students reported very favorable evaluations concerning their experience with creating “Ken Burns” video project documentaries.

Evolution of the Mobile Information SysTem (MIST)

NASA Technical Reports Server (NTRS)

Litaker, Harry L., Jr.; Thompson, Shelby; Archer, Ronald D.

2008-01-01

The Mobile Information SysTem (MIST) had its origins in the need to determine whether commercial off the shelf (COTS) technologies could improve intervehicular activities (IVA) on International Space Station (ISS) crew maintenance productivity. It began with an exploration of head mounted displays (HMDs), but quickly evolved to include voice recognition, mobile personal computing, and data collection. The unique characteristic of the MIST lies within its mobility, in which a vest is worn that contains a mini-computer and supporting equipment, and a headband with attachments for a HMD, lipstick camera, and microphone. Data is then captured directly by the computer running Morae(TM) or similar software for analysis. To date, the MIST system has been tested in numerous environments such as two parabolic flights on NASA's C-9 microgravity aircraft and several mockup facilities ranging from ISS to the Altair Lunar Sortie Lander. Functional capabilities have included its lightweight and compact design, commonality across systems and environments, and usefulness in remote collaboration. Human Factors evaluations of the system have proven the MIST's ability to be worn for long durations of time (approximately four continuous hours) with no adverse physical deficits, moderate operator compensation, and low workload being reported as measured by Corlett Bishop Discomfort Scale, Cooper-Harper Ratings, and the NASA Total Workload Index (TLX), respectively. Additionally, through development of the system, it has spawned several new applications useful in research. For example, by only employing the lipstick camera, microphone, and a compact digital video recorder (DVR), we created a portable, lightweight data collection device. Video is recorded from the participants point of view (POV) through the use of the camera mounted on the side of the head. Both the video and audio is recorded directly into the DVR located on a belt around the waist. This data is then transferred to another computer for video editing and analysis. Another application has been discovered using simulated flight, in which, a kneeboard is replaced with mini-computer and the HMD to project flight paths and glide slopes for lunar ascent. As technologies evolve, so will the system and its application for research and space system operations.

Content-based intermedia synchronization

NASA Astrophysics Data System (ADS)

Oh, Dong-Young; Sampath-Kumar, Srihari; Rangan, P. Venkat

1995-03-01

Inter-media synchronization methods developed until now have been based on syntactic timestamping of video frames and audio samples. These methods are not fully appropriate for the synchronization of multimedia objects which may have to be accessed individually by their contents, e.g. content-base data retrieval. We propose a content-based multimedia synchronization scheme in which a media stream is viewed as hierarchial composition of smaller objects which are logically structured based on the contents, and the synchronization is achieved by deriving temporal relations among logical units of media object. content-based synchronization offers several advantages such as, elimination of the need for time stamping, freedom from limitations of jitter, synchronization of independently captured media objects in video editing, and compensation for inherent asynchronies in capture times of video and audio.

In support of a project on porcine cysticercosis in Tanzania, an educational video was prepared to inform the rural communities on the health risks and prevention of the parasitic disease. This paper describes the process involved in making the video, especially the importance of establishing a good understanding between veterinary public health officials and the video producer. Important steps in the process include determining the target audience, the film's core message, the construction of the "story", script development, the filming and editing activities, and, importantly, the development of strategies for production and use of the film as extension material. Suggestions on logistical and technical aspects of filming and viewing are also discussed. The experience gained in Tanzania will be of value to others planning similar projects elsewhere.

Abdulali, S

1995-01-01

In India, illiterate women have been making films since 1984 undeterred by their former lack of experience in this area. Video SEWA (Self-Employed Widows Association) is composed of a collection of women from various backgrounds who have produced over 100 films, with 39 complete and available to the public. The films reflect the extraordinary nature of the women's backgrounds by covering such topics as how to build smokeless stoves. Video SEWA got its beginnings with the help of Martha Stewart, a New Yorker, who held a video production workshop. For three years, the women, who could not edit film, shot their films in sequence. In 1987, they learned to edit. One illiterate member of the permanent staff of four, a woman who memorized all of the symbols on the equipment as well as the content of the training workshops, produced as her first film an impassioned view of the harassment suffered by female produce vendors. Now all vendors in the area have licenses. The films cover a variety of topics and have been used to raise consciousness, for training, and to record significant events. The women hold regular training sessions and have ambitious plans for communication centers all over India. Film is a powerful medium in the hands of the powerless, and the status of the staff members in their private lives has been improved by their new abilities. The group is challenged by the scarcity of technical know-how in remote areas, by the prejudices of local film equipment experts, and by the vagaries of the national television networks. In its 11 years, however, Video SEWA has come far, and its accomplishments are being carried on by the next generation.

Introducing a Virtual Reality Experience in Anatomic Pathology Education.

PubMed

Madrigal, Emilio; Prajapati, Shyam; Hernandez-Prera, Juan C

2016-10-01

A proper examination of surgical specimens is fundamental in anatomic pathology (AP) education. However, the resources available to residents may not always be suitable for efficient skill acquisition. We propose a method to enhance AP education by introducing high-definition videos featuring methods for appropriate specimen handling, viewable on two-dimensional (2D) and stereoscopic three-dimensional (3D) platforms. A stereo camera system recorded the gross processing of commonly encountered specimens. Three edited videos, with instructional audio voiceovers, were experienced by nine junior residents in a crossover study to assess the effects of the exposure (2D vs 3D movie views) on self-reported physiologic symptoms. A questionnaire was used to analyze viewer acceptance. All surveyed residents found the videos beneficial in preparation to examine a new specimen type. Viewer data suggest an improvement in specimen handling confidence and knowledge and enthusiasm toward 3D technology. None of the participants encountered significant motion sickness. Our novel method provides the foundation to create a robust teaching library. AP is inherently a visual discipline, and by building on the strengths of traditional teaching methods, our dynamic approach allows viewers to appreciate the procedural actions involved in specimen processing. © American Society for Clinical Pathology, 2016.

Algorithms for Lunar Flash Video Search, Measurement, and Archiving

NASA Technical Reports Server (NTRS)

Swift, Wesley; Suggs, Robert; Cooke, Bill

2007-01-01

Lunar meteoroid impact flashes provide a method to estimate the flux of the large meteoroid flux and thus their hazard to spacecraft. Although meteoroid impacts on the Moon have been detected using video methods for over a decade, the difficulty of manually searching hours of video for the rare, extremely brief impact flashes has discouraged the technique's systematic implementation. A prototype has been developed for the purpose of automatically searching lunar video records for impact flashes, eliminating false detections, editing the returned possible flashes, Z and archiving and documenting the results. The theory and organization of the program is discussed with emphasis on the filtering out of several classes of false detections and retaining the brief portions of the raw video necessary for in depth analysis of the flashes detected. Several utilities for measurement, analysis, and location of the flashes on the moon included in the program are demonstrated. Application of the program to a year's worth of lunar observations is discussed along with examples of impact flashes as well as several classes of false impact flashes.

2014-12-01

Online videos and the social networks used to disseminate them provide scientists, educators, and students an opportunity to reach new audiences on a global scale. The ability to inspire people to think about a given subject that are not otherwise engaged is an important strategy in growing the societal impact of your work. Especially to those working in the field of physical science as it relates to environmental conservation and preservation, targeting new audiences helps avoid "preaching to the choir." Towards this goal, three graduate students at the Rosenstiel School of Marine and Atmospheric Science began an online film project in 2011 aimed at motivating the general public to think about their relationship with water and the marine environment. Here we present lessons from our first three years that include: tips for making an engaging video, promoting creativity and self-expression in science, video editing tips 101, getting the most out of your GoPro, and how to get your video seen by more people.

Latest Highlights from our Direct Measurement Video Collection

NASA Astrophysics Data System (ADS)

Vonk, M.; Bohacek, P. H.

2014-12-01

Recent advances in technology have made videos much easier to produce, edit, store, transfer, and view. This has spawned an explosion in a production of a wide variety of different types of pedagogical videos. But with the exception of student-made videos (which are often of poor quality) almost all of the educational videos being produced are passive. No matter how compelling the content, students are expected to simply sit and watch them. Because we feel that being engaged and active are necessary components of student learning, we have been working to create a free online library of Direct Measurement Videos (DMV's). These videos are short high-quality videos of real events, shot in a way that allows students to make measurements directly from the video. Instead of handing students a word problem about a car skidding on ice, we actually show them the car skidding on ice. We then ask them to measure the important quantities, make calculations based on those measurements and solve for unknowns. DMV's are more interesting than their word problem equivalents and frequently inspire further questions about the physics of the situation or about the uncertainty of the measurement in ways that word problems almost never do. We feel that it is simply impossible to a video of a roller coaster or a rocket and then argue that word problems are better. In this talk I will highlight some new additions to our DMV collection.

The relation between empathy subtypes and prosocial behavior was investigated in a sample of healthy adults. "Empathic concern" and "empathic happiness", defined as negative and positive vicarious emotion (respectively) combined with an other-oriented feeling of "goodwill" (i.e. a thought to do good to others/see others happy), were elicited in 68 adult participants who watched video clips extracted from the television show Extreme Makeover: Home Edition. Prosocial behavior was quantified via performance on a non-monetary altruistic decision-making task involving book selection and donation. Empathic concern and empathic happiness were measured via self-report (immediately following each video clip) and via facial electromyography recorded from corrugator (active during frowning) and zygomatic (active during smiling) facial regions. Facial electromyographic signs of (a) empathic concern (i.e. frowning) during sad video clips, and (b) empathic happiness (i.e. smiling) during happy video clips, predicted increased prosocial behavior in the form of increased goodwill-themed book selection/donation.

Can Video Self-Modeling Improve Affected Limb Reach and Grasp Ability in Stroke Patients?

PubMed

Steel, Kylie Ann; Mudie, Kurt; Sandoval, Remi; Anderson, David; Dogramaci, Sera; Rehmanjan, Mohammad; Birznieks, Ingvars

2018-01-01

The authors examined whether feedforward video self-modeling (FF VSM) would improve control over the affected limb, movement self-confidence, movement self-consciousness, and well-being in 18 stroke survivors. Participants completed a cup transport task and 2 questionnaires related to psychological processes pre- and postintervention. Pretest video footage of the unaffected limb performing the task was edited to create a best-of or mirror-reversed training DVD, creating the illusion that patients were performing proficiently with the affected limb. The training yielded significant improvements for the forward movement of the affected limb compared to the unaffected limb. Significant improvements were also seen in movement self-confidence, movement self-consciousness, and well-being. FF VSM appears to be a viable way to improve motor ability in populations with movement disorders.

Creating a Podcast/Vodcast: A How-To Approach

NASA Astrophysics Data System (ADS)

Petersen, C. C.

2011-09-01

Creating podcasts and vodcasts is a wonderful way to share news of science research. Public affairs officers use them to reveal the latest discoveries done by scientists in their institutions. Educators can offer podcast/vodcast creation for students who want a unique way to demonstrate their mastery of science topics. Anyone with a computer and a USB microphone can create a podcast. To do a vodcast, you also need a digital video camera and video editing software. This session focused mainly on creating a podcast - writing the script and recording the soundtrack. Attendees also did a short activity to learn to write effective narrative copy for a podcast/vodcast.

Study of information dissemination by satellite, volume 1

NASA Astrophysics Data System (ADS)

Connell, S.; Champness, B. G.; Stapley, B.; Winsbury, R.

1985-05-01

Western European demand for satellite information dissemination in the late 1990's was assessed. The major market opportunity lies in intra-organizational video communications. Broadcast satellites could be used to facilitate dispersal of newspaper printing sites and the development of regionalized or local editions. Examples would include the publication of editions of north European newspapers in Mediterranean holiday resorts. Data broadcasting services could use VBI or full channel teletext or other formats. The most promising area for data dissemination by satellite is the aggregation of a number of services which are themselves small, but in total could generate substantial demand. Examples of such services include dissemination of private company data to dispersed branches (pricing, stock levels, etc.).

Public Education and Outreach Through Full-Dome Video Technology

NASA Astrophysics Data System (ADS)

Pollock, John

2009-03-01

My long-term goal is to enhance public understanding of complex systems that can be best demonstrated through richly detailed computer graphic animation displayed with full-dome video technology. My current focus is on health science advances that focus on regenerative medicine, which helps the body heal itself. Such topics facilitate science learning and health literacy. My team develops multi-media presentations that bring the scientific and medical advances to the public through immersive high-definition video animation. Implicit in treating the topics of regenerative medicine will be the need to address stem cell biology. The topics are clarified and presented from a platform of facts and balanced ethical consideration. The production process includes communicating scientific information about the excitement and importance of stem cell research. Principles of function are emphasized over specific facts or terminology by focusing on a limited, but fundamental set of concepts. To achieve this, visually rich, biologically accurate 3D computer graphic environments are created to illustrate the cells, tissues and organs of interest. A suite of films are produced, and evaluated in pre- post-surveys assessing attitudes, knowledge and learning. Each film uses engaging interactive demonstrations to illustrate biological functions, the things that go wrong due to disease and disability, and the remedy provided by regenerative medicine. While the images are rich and detailed, the language is accessible and appropriate to the audience. The digital, high-definition video is also re-edited for presentation in other ``flat screen'' formats, increasing our distribution potential. Show content is also presented in an interactive web space (www.sepa.duq.edu) with complementing teacher resource guides and student workbooks and companion video games.

Concerns of Quality and Safety in Public Domain Surgical Education Videos: An Assessment of the Critical View of Safety in Frequently Used Laparoscopic Cholecystectomy Videos.

PubMed

Deal, Shanley B; Alseidi, Adnan A

2017-12-01

Online videos are among the most common resources for case preparation. Using crowd sourcing, we evaluated the relationship between operative quality and viewing characteristics of online laparoscopic cholecystectomy videos. We edited 160 online videos of laparoscopic cholecystectomy to 60 seconds or less. Crowd workers (CW) rated videos using Global Objective Assessment of Laparoscopic Skills (GOALS), the critical view of safety (CVS) criteria, and assigned overall pass/fail ratings if CVS was achieved; linear mixed effects models derived average ratings. Views, likes, dislikes, subscribers, and country were recorded for subset analysis of YouTube videos. Spearman correlation coefficient (SCC) assessed correlation between performance measures. One video (0.06%) achieved a passing CVS score of ≥5; 23%, ≥4; 44%, ≥3; 79%, ≥2; and 100% ≥1. Pass/fail ratings correlated to CVS, SCC 0.95 (p < 0.001) and to GOALS, SCC 0.79 (p < 0.001). YouTube videos (n = 139) with higher views, likes, or subscribers did not correlate with better quality. The average CVS and GOALS scores were no different for videos with >20,000 views (22%) compared with those with <20,000 (78%). There is an incredibly low frequency of CVS and average GOALS technical performance in frequently used online surgical videos of LC. Favorable characteristics, such as number of views or likes, do not translate to higher quality. Copyright © 2017 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

Objectives We examined whether problem-based learning tutorials using patient-simulated videos showing daily life are more practical for clinical learning, compared with traditional paper-based problem-based learning, for the consideration rate of psychosocial issues and the recall rate for experienced learning. Methods Twenty-two groups with 120 fifth-year students were each assigned paper-based problem-based learning and video-based problem-based learning using patient-simulated videos. We compared target achievement rates in questionnaires using the Wilcoxon signed-rank test and discussion contents diversity using the Mann-Whitney U test. A follow-up survey used a chi-square test to measure students’ recall of cases in three categories: video, paper, and non-experienced. Results Video-based problem-based learning displayed significantly higher achievement rates for imagining authentic patients (p=0.001), incorporating a comprehensive approach including psychosocial aspects (p<0.001), and satisfaction with sessions (p=0.001). No significant differences existed in the discussion contents diversity regarding the International Classification of Primary Care Second Edition codes and chapter types or in the rate of psychological codes. In a follow-up survey comparing video and paper groups to non-experienced groups, the rates were higher for video (χ2=24.319, p<0.001) and paper (χ2=11.134, p=0.001). Although the video rate tended to be higher than the paper rate, no significant difference was found between the two. Conclusions Patient-simulated videos showing daily life facilitate imagining true patients and support a comprehensive approach that fosters better memory. The clinical patient-simulated video method is more practical and clinical problem-based tutorials can be implemented if we create patient-simulated videos for each symptom as teaching materials.  PMID:28245193

SOFTWARE REVIEW: Multimedia Motion II. CD-ROM and Teacher's Guide

NASA Astrophysics Data System (ADS)

Scaife, Jon A.

2000-05-01

This CD is the second edition of Multimedia Motion. It is an excellent resource for learning about kinematics. To run the software requires at least a good 486 processor with Windows 9x or 3.1. I used a P166 with Win 98. The CD contains 36 video clips, or `movies', of events ranging from a space shuttle launch, sporting activities and vehicle crash tests to familiar laboratory air-track experiments. For each event there are options to access concise on-screen notes and an audio commentary. The emphasis is strongly on user activity. The software design is very good, stimulating and supporting the user to think and make decisions about physics. `Inauthentic labour' is largely dealt with by the programme, and the result is that there is a high thinking-time to using-time ratio. The application is easy to install from scratch (it took under three minutes from first opening the box to running it for real). Basic use is as follows: you play a video clip through to get an idea of its contents. This takes a few seconds. Then you play it again, step by step, using the mouse to track a particular point of interest as it moves in the video (e.g. the tip of the space shuttle or the centre of a tennis ball). This results in a data set of x, y and t coordinates. The data can be plotted immediately, not only as x or y versus time but also with velocity or acceleration as the ordinate. There is an option for curve fitting, and if a linear or quadratic fit is chosen, the equation is displayed, from which it is simple to obtain gradients and intercepts, terms that often have significance in the physical system. It might be inferred from above that the package is designed for A-level and upper GCSE. While this is so, it could also be used with younger secondary students. The software is transparent and data gathering and graph plotting are very easy. The difference in the use of the application with younger students will be in the level of interpretation that the teacher would expect. This is an issue that is in the teacher's hands; the package is flexible enough to accommodate a wide range of learning aims. Audio clips are brief and to the point, with both female and male speakers. The commentary goes beyond the descriptive, raising interesting questions and issues and setting challenges for the user. The optional screen text is pitched at A-level. Video clips can be viewed at full screen, which is a big improvement over the first edition. There are some new clips and a few omissions from the first edition; further CDs of movie data are planned. Clips may be played forwards or backwards at various speeds using a scroll bar. This allows close control and analysis, which is useful for critical events in which changes are rapid, such as collisions. Printing of data and graphs is straightforward and the results are clear. Unlike the first edition, Multimedia Motion II only gives direct support to graphs with time as the abscissa. For graphs such as v(x) versus v(y), however, it is a simple matter to save the data directly into Excel or another spreadsheet. I encountered only one snag in using the CD: if I forgot to save my data before moving to a new clip I could not recover it. This failing could be mine, but I did try hard. The Teacher's Guide contains photocopiable worksheets and detailed discussion and graphs of the video clips. For each clip there is a section of `useful data and formulae'. The guide is not a necessity for using the CD-ROM but it would be a very handy A-level teaching resource, allowing the option of independent use by students. It is accompanied by a floppy disc containing sets of experimental data for the video clips, a useful option for quick demonstrations. In addition, the guide explains the interesting and creative option of making your own movie sequences from videotape, though access to a video card would be needed to do this. Imagine the motivational value of students recording themselves playing various sports, or even just riding a bike, and then analysing their own kinematic behaviour on the computer! In summary, this package has a lot to offer in the teaching of kinematics. It can be used in its full glory at A-level but has much to offer at, or even before, GCSE. It allows for the nearest realistic thing to direct experimentation in a wide range of well-chosen examples of motion.

Proposal of a Video-recording System for the Assessment of Bell's Palsy: Methodology and Preliminary Results.

To propose a new objective video-recording procedure to assess and monitor over time the severity of facial nerve palsy. No objective methods for facial palsy (FP) assessment are universally accepted. The face of subjects presenting with different degrees of facial nerve deficit, as measured by the House-Brackmann (HB) grading system, was videotaped after positioning, at specific points, 10 gray circular markers made of a retroreflective material. Video-recording included the resting position and six ordered facial movements. Editing and data elaboration was performed using a software instructed to assess marker distances. From the differences of the marker distances between the two sides was then extracted a score. The higher the FP degree, the higher the score registered during each movement. The statistical significance differed during the various movements between the different FP degrees, being uniform when closing the eyes gently; whereas when wrinkling the nose, there was no difference between the HB grade III and IV groups and, when smiling, no difference was evidenced between the HB grade IV and V groups.The global range index, which represents the overall degree of FP, was between 6.2 and 7.9 in the normal subjects (HB grade I); between 10.6 and 18.91 in HB grade II; between 22.19 and 33.06 in HB grade III; between 38.61 and 49.75 in HB grade IV; and between 50.97 and 66.88 in HB grade V. The proposed objective methodology could provide numerical data that correspond to the different degrees of FP, as assessed by the subjective HB grading system. These data can in addition be used singularly to score selected areas of the paralyzed face when recovery occurs with a different timing in the different face regions.

To evaluate the effectiveness of an educational video in increasing knowledge among glaucoma patients and to determine the factors that may influence a patient's level of knowledge. This was a pre-post intervention study on adult glaucoma patients attending the outpatient service at King Khaled Eye Specialist Hospital. The intervention tested was a short educational video that was edited specifically for this study. All patients completed a pre-video and post-video knowledge questionnaire; moreover, sociodemographic and clinical characteristics were obtained. The total number of patients included was 196. The mean age of patients was 55.7±15.5 years. Overall, 55.1% were males, 29.6% were illiterate, 85.2% resided in an urban area, 62.8% had a low income, and 41.8% were unemployed. The mean pre-intervention knowledge score was 6 out of 17, and the post-intervention score was 11.1 ( P ≤0.001). Predictors of a poor knowledge score were old age (>60 years), female sex, illiteracy, rural residence, low income, unemployment, and a negative family history of glaucoma. The evaluated video intervention was effective in a short-term increase in knowledge among glaucoma patients. This tool may serve as an alternative to traditional educational methods.

Prospectus 2000

Holmes, Jon L.; Gettys, Nancy S.

2000-01-01

We begin 2000 with a message about our plans for JCE Software and what you will be seeing in this column as the year progresses. Floppy Disk --> CD-ROM Most software today is distributed on CD-ROM or by downloading from the Internet. Several new computers no longer include a floppy disk drive as "standard equipment". Today's software no longer fits on one or two floppies (the installation software alone can require two disks) and the cost of reproducing and distributing several disks is prohibitive. In short, distribution of software on floppy disks is no longer practical. Therefore, JCE Software will distribute all new software publications on CD-ROM rather than on disks. Regular Issues --> Collections Distribution of all our software on CD-ROM allows us to extend our concept of software collections that we started with the General Chemistry Collection. Such collections will contain all the previously published software that is still "in print" (i.e., is compatible with current operating systems and hardware) and any new programs that fall under the topic of the collection. Proposed topics in addition to General Chemistry currently include Advanced Chemistry, Instrument and Laboratory Simulations, and Spectroscopy. Eventually, all regular issues will be replaced by these collections, which will be updated annually or semiannually with new programs and updates to existing programs. Abstracts for all new programs will continue to appear in this column when a collection or its update is ready for publication. We will continue to offer special issues of single larger programs (e.g. Periodic Table Live!, Chemistry Comes Alive! volumes) on CD-ROM and video on videotape. Connect with Your Students outside Class JCE Software has always offered network licenses to allow instructors to make our software available to students in computer labs, but that model no longer fits the way many instructors and students work with computers. Many students (or their families) own a personal computer allowing them much more flexibility than a campus computer lab. Many instructors utilize the World Wide Web, creating HTML pages for students to use. JCE Software has options available to take advantage of both of these developments. Software Adoption To provide students who own computers access to JCE Software programs, consider adopting one or more of our CD-ROMs as you would a textbook. The General Chemistry Collection has been adopted by several general chemistry courses. We can arrange to bundle CDs with laboratory manuals or to be sold separately to students through the campus bookstore. The cost per CD can be quite low (as little as $5) when large numbers are ordered, making this a cost-effective method of allowing students access to the software they need whenever and wherever they desire. Web-Ready Publications Several JCE Software programs use HTML to present the material. Viewed with the ubiquitous Internet Browser, HTML is compatible with both Mac OS and Windows (as well most other current operating systems) and provides a flexible hypermedia interface that is familiar to an increasing number of instructors and students. HTML-based publications are also ready for use on local intranets, with appropriate licensing, and can be readily incorporated into other HTML-based materials. Already published in this format are: Chemistry Comes Alive!, Volumes 1 and 2 (Special Issues 18 and 21), Flying over Atoms (Special Issue 19), and Periodic Table Live! Second Edition (Special Issue 17). Solid State Resources Second Edition (Special Issue 12) and Chemistry Comes Alive!, Volume 3 (Special Issue 23) will be available soon. Other submissions being developed in HTML format include ChemPages Laboratory and Multimedia General Chemistry Problems. Contact the JCE Software office to learn about licensing alternatives that take advantage of the World Wide Web. Periodic Table Live! 2nd ed. is one of JCE Software's "Web-ready" publications. Publication Plans for 2000 We have several exciting new issues planned for publication in the coming year. Chemistry Comes Alive! The Chemistry Comes Alive! (CCA!) series continues with additional CD-ROMs for Mac OS and Windows. Each volume in this series contains video and animations of chemical reactions that can be easily incorporated into your own computer-based presentations. Our digital video now uses state-of-the-art compression that yields higher quality video with smaller file sizes and data rates more suited for WWW delivery. Video for Periodic Table Live! 2nd edition, Chemistry Comes Alive! Volumes 3, ChemPages Laboratory, and Multimedia General Chemistry Problems use this new format. We will be releasing updates of CCA! Volumes 1 and 2 to take advantage of this new technology. We are very pleased with the results and think you will be also. The reaction of aluminum with chlorine is included in Chemistry Comes Alive! Volume 3. ChemPages Laboratory ChemPages Laboratory, developed by the New Traditions Curriculum Project at the University of Wisconsin-Madison, is an HTML-based CD-ROM for Mac OS and Windows that contains lessons and tutorials to prepare introductory chemistry students to work in the laboratory. It includes text, photographs, computer graphics, animations, digital video, and voice narration to introduce students to the laboratory equipment and procedures. ChemPages Laboratory teaches introductory chemistry students about laboratory instruments, equipment, and procedures. Versatile Video Video demonstrating the "drinking bird" is included in the Chemistry Comes Alive! video collection. Video from this collection can be incorporated into many other projects. As an example, David Whisnant has used the drinking bird in his Multimedia General Chemistry Problems, where students view the video and are asked to explain why the bird bobs up and down. JCE Software anticipates publication of Multimedia General Chemistry Problems on CD-ROM for Mac OS and Windows in 2000. It will be "Web-ready". General Chemistry Collection, 4th Edition The General Chemistry Collection will be revised early in the summer and CDs will be shipped in time for fall adoptions. The 4th edition will include JCE Software publications for general chemistry published in 1999, as well as any programs for general chemistry accepted in 2000.

A Web Browsing System by Eye-gaze Input

NASA Astrophysics Data System (ADS)

Abe, Kiyohiko; Owada, Kosuke; Ohi, Shoichi; Ohyama, Minoru

We have developed an eye-gaze input system for people with severe physical disabilities, such as amyotrophic lateral sclerosis (ALS) patients. This system utilizes a personal computer and a home video camera to detect eye-gaze under natural light. The system detects both vertical and horizontal eye-gaze by simple image analysis, and does not require special image processing units or sensors. We also developed the platform for eye-gaze input based on our system. In this paper, we propose a new web browsing system for physically disabled computer users as an application of the platform for eye-gaze input. The proposed web browsing system uses a method of direct indicator selection. The method categorizes indicators by their function. These indicators are hierarchized relations; users can select the felicitous function by switching indicators group. This system also analyzes the location of selectable object on web page, such as hyperlink, radio button, edit box, etc. This system stores the locations of these objects, in other words, the mouse cursor skips to the object of candidate input. Therefore it enables web browsing at a faster pace.

Video self-modeling in children with autism: a pilot study validating prerequisite skills and extending the utilization of VSM across skill sets.

PubMed

Williamson, Robert L; Casey, Laura B; Robertson, Janna Siegel; Buggey, Tom

2013-01-01

Given the recent interest in the use of video self-modeling (VSM) to provide instruction within iPod apps and other pieces of handheld mobile assistive technologies, investigating appropriate prerequisite skills for effective use of this intervention is particularly timely and relevant. To provide additional information regarding the efficacy of VSM for students with autism and to provide insights into any possible prerequisite skills students may require for such efficacy, the authors investigated the use of VSM in increasing the instances of effective initiations of interpersonal greetings for three students with autism that exhibited different pre-intervention abilities. Results showed that only one of the three participants showed an increase in self-initiated greetings following the viewing of videos edited to show each participant self-modeling a greeting when entering his or her classroom. Due to the differences in initial skill sets between the three children, this finding supports anecdotally observed student prerequisite abilities mentioned in previous studies that may be required to effectively utilize video based teaching methods.

Rack, F. R.; Tauxe, K.

2004-12-01

In May 2002, Joint Oceanographic Institutions (JOI) received a proposal entitled "Motivating Middle School Students with the JOIDES Resolution", from a middle school teacher in New Mexico named Katie Tauxe. Katie was a former Marine Technician who has worked aboard the R/V JOIDES Resolution in the early years of the Ocean Drilling Program (ODP). She proposed to engage the interest of middle school students using the ODP drillship as the centerpiece of a presentation focused on the lives of the people who work aboard the ship and the excitement of science communicated through an active shipboard experience. The proposal asked for travel funds to and from the ship, the loan of video camera equipment from JOI, and a small amount of funding to cover expendable supplies, video editing, and production at the local Public Broadcasting Station in Los Alamos, NM. Katie sailed on the transit of the JOIDES Resolution through the Panama Canal, following the completion of ODP Leg 206 in late 2002. This presentation will focus on the outcome of this video production effort, which is a 19 minute-long video entitled "Out to Sea: Life as a Crew Member Aboard a Geologic Research Ship", and a teacher's guide that can be found online.

Stereoscopic video teaching can facilitate understanding for current minimally-invasive operative techniques. This project was created to set up a digital stereoscopic teaching environment for training of ENT residents and medical students. We recorded three ENT operative procedures (tympanoplasty, paranasal sinus operation and laser chordectomy) at the University Hospital Aachen. The material was edited stereoscopically at the Waseda University and converted into a streaming 3-D video format, which does not depend on PAL or NTSC signal standards. Video clips were evaluated by 5 ENT specialists and 11 residents in single sessions on an LCD monitor (8) and a CRT monitor (8). Emphasis was laid on depth perception, visual fatigue and time to achieve stereoscopic impression. Qualitative results were recorded on a visual analogue scale, ranging from 1 (excellent) to 5 (bad). The overall impression was rated 2,06 to 3,13 in the LCD group and 2,0 to 2,62 in the CRT group. The depth impression was rated 1,63 to 2,88 (LCD) and 1,63 to 2,25 (CRT). Stereoscopic video teaching was regarded as useful in ENT training by all participants. Further points for evaluation will be the quantification of depth information as well as the information gain in teaching junior colleagues.

To develop a revised edition of the Bimanual Fine Motor Function (BFMF 2), as a classification of fine motor capacity in children with cerebral palsy (CP), and establish intra- and interrater reliability of this edition. The content of the original BFMF was discussed by an expert panel, resulting in a revised edition comprising the original description of the classification levels, but in addition including figures with specific explanatory text. Four professionals classified fine motor function of 79 children (3-17 years; 45 boys) who represented all subtypes of CP and Manual Ability Classification levels (I-V). Intra- and inter-rater reliability was assessed using overall intra-class correlation coefficient (ICC), and Cohen's quadratic weighted kappa. The overall ICC was 0.86. Cohen's weighted kappa indicated high intra-rater (к w : >0.90) and inter-rater (к w : >0.85) reliability. The revised BFMF 2 had high intra- and interrater reliability. The classification levels could be determined from short video recordings (<5 minutes), using the figures and precise descriptions of the fine motor function levels included in the BFMF 2. Thus, the BFMF 2 may be a feasible and useful classification of fine motor capacity both in research and in clinical practice.

Electronic photography: a new age of medical imaging?

This is a critical overview of present conceptions of the introduction of electronic photography in medicine. It is not a complete list of products, rather it is a description of how the requirements of the physician have influenced medical illustration in the past and will continue to do so in the future. Video systems are widely used in medicine. Besides the learning and teaching of effects of television, minimal invasive surgery (MIS) has become reality through endoscopy, rapidly accepted worldwide. Documentation of endoscopic procedures and their effects is becoming routine. Therefore, the conversion of complex optical information into binary units is a logical development to save space for storage. The reproduction, storage and transfer of detailed images is already realized by digital camera systems, photo CD, scanners and picture archiving and communicating system (PACS). Now electronic imaging in medicine has to be regarded as a matter of routine. The real impact of accelerated editing will be shown in the future.

Google started the WebM Project in 2010 to develop open source, royalty- free video codecs designed specifically for media on the Web. The second generation codec released by the WebM project, VP9, is currently served by YouTube, and enjoys billions of views per day. Realizing the need for even greater compression efficiency to cope with the growing demand for video on the web, the WebM team embarked on an ambitious project to develop a next edition codec AV1, in a consortium of major tech companies called the Alliance for Open Media, that achieves at least a generational improvement in coding efficiency over VP9. In this paper, we focus primarily on new tools in AV1 that improve the prediction of pixel blocks before transforms, quantization and entropy coding are invoked. Specifically, we describe tools and coding modes that improve intra, inter and combined inter-intra prediction. Results are presented on standard test sets.

Development of the Italian version of the National Institutes of Health Stroke Scale: It-NIHSS.

The National Institutes of Health Stroke Scale (NIHSS) is a basic component of the assessment of patients with acute stroke. To foster and standardize the use of the NIHSS among Italian health professionals, we translated the scale, dubbed into Italian the training and test videotapes devised by the National Institutes of Health researchers, and conducted a series of certification courses using the translated videos. Translation, text adaptation, video dubbing, and editing of the Italian NIHSS videotapes relied on a team of bilingual stroke neurologists. Three waves of training courses were organized for mixed classes of medical and nonmedical health professionals. The certification test was based on the usual set of 5 videotaped patients. Scoring rules were those provided by the National Institutes of Neurological Disorders and Stroke. Reliability of the Italian NIHSS was assessed using kappa statistics and compared with that of the original NIHSS. During 3 years, 850 nurses, 460 nonneurologist physicians, and 246 neurologists were trained. Pass rates were respectively 44%, 75%, and 87%, respectively. Overall, 80% of scale items showed moderate to excellent reliability. Independent significant predictors of test failure at multivariate logistic regression were nurse profession (OR, 5.41; 95% CI, 4.07 to 7.20), older age (OR, 1.03; 95% CI, 1.02 to 1.05), and first edition of the course (OR, 3.13; 95% CI, 2.43 to 4.05). The agreement across all items between NIHSS and the Italian NIHSS was 80% (kappa=0.70+/-0.18, z<0.001). The Italian translation, supervised by experienced vascular neurologists, did not influence the clinimetric characteristics of the NIHSS. Our findings support the implementation of NIHSS video training in languages other than English.

Intelligent indexing: a semi-automated, trainable system for field labeling

Clawson, Robert; Barrett, William

2015-01-01

We present Intelligent Indexing: a general, scalable, collaborative approach to indexing and transcription of non-machinereadable documents that exploits visual consensus and group labeling while harnessing human recognition and domain expertise. In our system, indexers work directly on the page, and with minimal context switching can navigate the page, enter labels, and interact with the recognition engine. Interaction with the recognition engine occurs through preview windows that allow the indexer to quickly verify and correct recommendations. This interaction is far superior to conventional, tedious, inefficient post-correction and editing. Intelligent Indexing is a trainable system that improves over time and can provide benefit even without prior knowledge. A user study was performed to compare Intelligent Indexing to a basic, manual indexing system. Volunteers report that using Intelligent Indexing is less mentally fatiguing and more enjoyable than the manual indexing system. Their results also show that it reduces significantly (30.2%) the time required to index census records, while maintaining comparable accuracy.

We investigated the superiority of the 8th edition of the tumor-node-metastasis (TNM) system for patients in China with gastric cancer. The survival outcomes of 1663 patients with gastric cancer undergoing radical resection were analyzed. In the 8th edition system, homogeneous 5-year survival rates among different pathological TNM (pTNM) categories belonging to the same stage were observed. However, in the 7th edition system, the differences of 5-year survival rate among pTNM categories belonging to the same stage were observed in stages IIB (P = 0.010), IIIB (P = 0.004), and IIIC (P < 0.001). For patients in the pT1-3 (P < 0.001) and pT4a (P < 0.001) categories, there were significant differences in survival between patients in the pN3a and pN3b categories. Furthermore, partial cases (pT4bN0M0/T4aN2M0) of stage IIIB were downstaged to stage IIIA in the 8th edition system, and the 5-year survival rate of these patients was significantly better than that of patients in stage IIIB in the 8th edition system. Similarly, the 5-year survival rate of patients in p4bN2M0/T4aN3aM0 downstaged from stage IIIC to IIIB was significantly better than that of patients in stage IIIC. Compared with the 7th edition system, the 8th edition system had a higher likelihood ratio and linear trend chi-squared score and a smaller Akaike information criteria value. The 8th edition system is superior to the 7th edition system in terms of homogeneity, discriminatory ability, and monotonicity of gradients for Chinese patients with gastric cancer.

Case, A. W.; Gross, N. A.; Spence, H. E.

2008-12-01

The term "radiation" can cause significant anxiety to a general audience in part because of the associated health risks, but also because of lack of a conceptual framework about the nature of radiation. A visual depiction of radiation may go a long way towards providing just such a framework. The CRaTER Team had an opportunity to create just such a video. The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) is a radiation instrument that will fly on the Lunar Reconnaissance Orbiter (LRO) and is designed to determine the effects of energetic particles on living tissue. In order to calibrate CRaTER and characterize its reaction to various radiation environments, the CRaTER team has used particle beam facilities include the Proton Radiation Therapy Facility at Massachusetts General Hospital (MGH). During one of the sessions at MGH, the team placed an off the shelf web camera into the beam and recorded the visual effects. This video recording was used as the basis for an edited video describing what was done and the results. The hope is that this video will provide a general audience with a visual framework for the nature and effects of radiation

NASA Dryden's Lori Losey was named NASA's 2004 Videographer of the Year in part for her camera work during NASA's AirSAR 2004 science mission in Chile.

2004-03-11

Lori Losey, an employee of Arcata Associates at Dryden, was honored with NASA's 2004 Videographer of the Year award for her work in two of the three categories in the NASA video competition, public affairs and documentation. In the public affairs category, Losey received a first-place citation for her footage of an Earth Science mission that was flown aboard NASA's DC-8 Flying Laboratory in South America last year. Her footage not only depicted the work of the scientists aboard the aircraft and on the ground, but she also obtained spectacular footage of flora and fauna in the mission's target area that helped communicate the environmental research goals of the project. Losey also took first place in the documentation category for her acquisition of technical videography of the X-45A Unmanned Combat Air Vehicle flight tests. The video, shot with a hand-held camera from the rear seat of a NASA F/A-18 mission support aircraft, demonstrated her capabilities in recording precise technical visual data in a very challenging airborne environment. The award was presented to Losey during a NASA reception at the National Association of Broadcasters convention in Las Vegas April 19. A three-judge panel evaluated entries for public affairs, documentation and production videography on professional excellence, technical quality, originality, creativity within restrictions of the project, and applicability to NASA and its mission. Entries consisted of a continuous video sequence or three views of the same subject for a maximum of three minutes duration. Linda Peters, Arcata Associates' Video Systems Supervisor at NASA Dryden, noted, "Lori is a talented videographer who has demonstrated extraordinary abilities with the many opportunities she has received in her career at NASA." Losey's award was the second major NASA video award won by members of the Dryden video team in two years. Steve Parcel took first place in the documentation category last year for his camera and editing

YouTube: An emerging tool in anatomy education.

Jaffar, Akram Abood

2012-01-01

The use of online social networks in medical education can remodel and enhance anatomy teaching and learning; one such network is the video-sharing site YouTube. Limited research in the literature exists on the use of YouTube as a platform for anatomy education. The aim of this study is to assess student's perceptions and patterns of usage of this resource, as well as the effectiveness of YouTube videos within a problem-based learning (PBL) curriculum. The study was conducted on 91 second-year medical students for whom video links were suggested throughout the academic year. In addition, the Human Anatomy Education (HAE) Channel was launched on YouTube to support classroom teaching with videos that emphasized applied aspects of anatomy. The results demonstrated that 98% of the students used YouTube as an online information resource, albeit in different frequencies. Out of the 86% who have been to the HAE Channel, 92% agreed/strongly agreed that the channel helped them learn anatomy. The study also reports the popularity of and awareness about using YouTube as a social network as well as in learning. Based on these findings, YouTube can be considered as an effective tool to enhance anatomy instruction if the videos are scrutinized, diversified, and aimed toward course objectives. Faculty of average computer literacy should be enabled to produce videos on their own YouTube channels to support independent learning and integration in a PBL curriculum. The methods described for capturing and editing the videos can be used as a prototype. Copyright © 2012 American Association of Anatomists.

Comparison Between Various Color Spectra and Conventional Grayscale Imaging for Detection of Parenchymal Liver Lesions With B-Mode Sonography.

The electronic colorization of grayscale B-mode sonograms using various color schemes aims to enhance the adaptability and practicability of B-mode sonography in daylight conditions. The purpose of this study was to determine the diagnostic effectiveness and importance of colorized B-mode sonography. Fifty-three video sequences of sonographic examinations of the liver were digitized and subsequently colorized in 2 different color combinations (yellow-brown and blue-white). The set of 53 images consisted of 33 with isoechoic masses, 8 with obvious lesions of the liver (hypoechoic or hyperechoic), and 12 with inconspicuous reference images of the liver. The video sequences were combined in a random order and edited into half-hour video clips. Isoechoic liver lesions were successfully detected in 58% of the yellow-brown video sequences and in 57% of the grayscale video sequences (P = .74, not significant). Fifty percent of the isoechoic liver lesions were successfully detected in the blue-white video sequences, as opposed to a 55% detection rate in the corresponding grayscale video sequences (P= .11, not significant). In 2 subgroups, significantly more liver lesions were detected with grayscale sonography compared to blue-white sonography. Yellow-brown-colorized B-mode sonography appears to be similarly effective for detection of isoechoic parenchymal liver lesions as traditional grayscale sonography. Blue-white colorization in B-mode sonography is probably not as effective as grayscale sonography, although a statistically significant disadvantage was shown only in the subgroup of hyperechoic liver lesions. © 2015 by the American Institute of Ultrasound in Medicine.

Establishing a gold standard for manual cough counting: video versus digital audio recordings

PubMed Central

Smith, Jaclyn A; Earis, John E; Woodcock, Ashley A

2006-01-01

Background Manual cough counting is time-consuming and laborious; however it is the standard to which automated cough monitoring devices must be compared. We have compared manual cough counting from video recordings with manual cough counting from digital audio recordings. Methods We studied 8 patients with chronic cough, overnight in laboratory conditions (diagnoses were 5 asthma, 1 rhinitis, 1 gastro-oesophageal reflux disease and 1 idiopathic cough). Coughs were recorded simultaneously using a video camera with infrared lighting and digital sound recording. The numbers of coughs in each 8 hour recording were counted manually, by a trained observer, in real time from the video recordings and using audio-editing software from the digital sound recordings. Results The median cough frequency was 17.8 (IQR 5.9–28.7) cough sounds per hour in the video recordings and 17.7 (6.0–29.4) coughs per hour in the digital sound recordings. There was excellent agreement between the video and digital audio cough rates; mean difference of -0.3 coughs per hour (SD ± 0.6), 95% limits of agreement -1.5 to +0.9 coughs per hour. Video recordings had poorer sound quality even in controlled conditions and can only be analysed in real time (8 hours per recording). Digital sound recordings required 2–4 hours of analysis per recording. Conclusion Manual counting of cough sounds from digital audio recordings has excellent agreement with simultaneous video recordings in laboratory conditions. We suggest that ambulatory digital audio recording is therefore ideal for validating future cough monitoring devices, as this as this can be performed in the patients own environment. PMID:16887019

Active Galactic Videos is an astronomy-focused YouTube channel run by a team at the University of Arizona. The channel both produces astronomy-focused educational content for public audiences and opens a window into the world of professional astronomy by showcasing the work done at Steward Observatory and in Southern Arizona. The channel is mainly run by undergraduate students from a variety of backgrounds including: astronomy, education, film, music, english, and writing. In addition to providing educational content for public audiences, this project provides opportunities for undergraduate students to learn about astronomy content, general astronomy pedagogy, as well as science communication. This is done through developing the practical skills needed to take on the challenge of creating effective and engaging videos. Students write, film, score, direct, and edit each video while conscious of how each piece can affect the teaching/storytelling of the concept at hand. The team has produced various styles of video: presentational, interviews, musical/poetic, tours, and documentaries. In addition to YouTube, the Active Galactic Videos team maintains a social media presence on Facebook, Twitter, and Instagram. These help to widely distribute the content as well as to publicize the main Youtube channel. In addition to providing an overview of our educational work, we present 51 videos, or two year's, worth of online analytics that we are using to better understand our audience, to examine what videos have been popular and successful, and how people are accessing our content. We will present our experience in order to help others learn about improving astronomy education online, as well as astronomy communication and outreach in general.We acknowledge the Howard Hughes Medical Institute for grant support of this and related education initiatives

Base editor (BE), containing a cytidine deaminase and catalytically defective Cas9, has been widely used to perform base editing. However, the narrow editing window of BE limits its utility. Here, we developed a new editing technology named as base editor for programming larger C to U (T) scope (BE-PLUS) by fusing 10 copies of GCN4 peptide to nCas9(D10A) for recruiting scFv-APOBEC-UGI-GB1 to the target sites. The new system achieves base editing with a broadened window, resulting in an increased genome-targeting scope. Interestingly, the new system yielded much fewer unwanted indels and non-C-to-T conversions. We also demonstrated its potential use in gene disruption across the whole genome through induction of stop codons (iSTOP). Taken together, the BE-PLUS system offers a new editing tool with increased editing window and enhanced fidelity.

Zhengleibencao (Classified Materia Medica) had been formed into several kinds of edition systems during its dissemination, among which there was the edition system of Daquanbencao (Complete Collection of Materia Medica). Daquanbencao was originally carved in the Jin dynasty, thereafter it was re-carved in the Yuan, Ming and Qing dynasties so as to form a series of editions such as the edition of Zhenyou in the second year of the Jin dynasty; the edition of the Zongwenshuyuan college in Dade renyan year of the Yuan dynasty; the WANG Qiu's carved edition of Shangyitang hall in the Ming dynasty; the carved edition of Jishanshuyuan, the Jishang mountain college in the Ming dynasty, the reprinted edition of PENG Duan-wu in the Ming dynasty, the supplementary edition of YANG Bi-da in the Qing dynasty;, and the carved edition of KE Feng-shi in the Qing dynasty. Among all the editions, Chongkanjingshizhengleidaquanbencao (Reprinted Classified Daquan Materia Medica from Historical Classics) was the representative one. As a representative of the above editions, the carved edition of WANG took the edition of the Zongwenshuyuan college of the Yuan dynasty as the original edition, but the images picture of materia medica adopted from the edition of Zhenghebencao (Materia Medica of the Zhenghe era).

Genome edited animals: Learning from GM crops?

PubMed

Bruce, Ann

2017-06-01

Genome editing of livestock is poised to become commercial reality, yet questions remain as to appropriate regulation, potential impact on the industry sector and public acceptability of products. This paper looks at how genome editing of livestock has attempted to learn some of the lessons from commercialisation of GM crops, and takes a systemic approach to explore some of the complexity and ambiguity in incorporating genome edited animals in a food production system. Current applications of genome editing are considered, viewed from the perspective of past technological applications. The question of what is genome editing, and can it be considered natural is examined. The implications of regulation on development of different sectors of livestock production systems are studied, with a particular focus on the veterinary sector. From an EU perspective, regulation of genome edited animals, although not necessarily the same as for GM crops, is advocated from a number of different perspectives. This paper aims to open up new avenues of research on genome edited animals, extending from the current primary focus on science and regulation, to engage with a wider-range of food system actors.

Methods and Applications of CRISPR-Mediated Base Editing in Eukaryotic Genomes.

The past several years have seen an explosion in development of applications for the CRISPR-Cas9 system, from efficient genome editing, to high-throughput screening, to recruitment of a range of DNA and chromatin-modifying enzymes. While homology-directed repair (HDR) coupled with Cas9 nuclease cleavage has been used with great success to repair and re-write genomes, recently developed base-editing systems present a useful orthogonal strategy to engineer nucleotide substitutions. Base editing relies on recruitment of cytidine deaminases to introduce changes (rather than double-stranded breaks and donor templates) and offers potential improvements in efficiency while limiting damage and simplifying the delivery of editing machinery. At the same time, these systems enable novel mutagenesis strategies to introduce sequence diversity for engineering and discovery. Here, we review the different base-editing platforms, including their deaminase recruitment strategies and editing outcomes, and compare them to other CRISPR genome-editing technologies. Additionally, we discuss how these systems have been applied in therapeutic, engineering, and research settings. Lastly, we explore future directions of this emerging technology.

Country watch. Brazil.

Szterenfeld, C; Lopes, V

1993-01-01

A fictional story using publicity-type language was depicted in an AIDS prevention video produced by the Health in Prostitution Project in Rio de Janeiro to support its work with prostitutes. The video was produced through the volunteer efforts of a professional cast and crew who used cultural entertainment codes to raise awareness. Although both established and new actors participated, the cast was comprised of largely famous soap opera and movie artists. This approach was chosen was the understanding that Brazilians watch soap operas 4-5 hours/day and would therefore readily recognize and pay attention to messages conveyed by the protagonists. The video was shot 2 weeks before Carnival when most actors usually rest and received wide media coverage and attention from the public sector. Prostitutes participated in all stages of production, from script-writing to casting to final editing. The video, Venus Fire, describes a pleasure lottery of which the prize is a lucky condom. The video was officially released on World AIDS Day 1992, and broadcast nationwide in January 1993. It was then subsequently aired in public squares and other street worker sites with question-and-answer sessions and public debates among average audience of 200-300 people. Similar health projects elsewhere in Brazil have also show the film with very good audience response. The prostitutes are happy that their profession is being treated with respect, while clients are attracted by the sexy images.

As part of the 'Science for Our Nation's Energy Future, Summit and Forum', each of the 46 Energy Frontier Research Centers (EFRCs) created in 2009 by the US Department of Energy was invited to design a short, engaging film with the central goal to educate, inspire, and entertain an intelligent but not expert audience about the extraordinary science, innovation and people in their center. The Center for Nanoscale Control of Geological CO2 (NCGC) is an EFRC that is building a next generation understanding of molecular-to-pore-scale processes critical to controlling the flow,transport, and ultimate mineralization in porous rock media, in particular as applied to geologic sequestration of CO2. In response to the invitation, the NCGC assembled a team that included several young scientists, the Center project manager, and members from the Public Affairs and Creative Services Office of the Lawrence Berkeley National Laboratory with the objective of preparing a submission. A videographer from the Creative Services Office was responsible for overall management including production, art direction, and editing, while scientists from the Center were responsible for scientific content and original storyline concept. The Center project manager facilitated the communication between team members. A group of scientists together with the project manager developed the original idea, which was refined and given shape as a script in dialogue form by a science writer from Public Affairs. The objective was to communicate scientific content in an entertaining manner with a simple storyline. In a second phase, the script was revised further by scientists for content. Clips from experiments and modeling simulations were requested from the Center's scientists to illustrate the scientific content. Video production and animation were done by the videographer and an animator in an iterative process that involve feedback from the Center team. The final cut was edited to meet the maximum length requirements set in the submission rules. The video was posted on Berkeley Lab's YouTube channel and was one of five winning entries in the Life at the Frontiers of Energy Research video contest.

Calvelo Rios, J M

1989-01-01

Peru developed its first use of video for training and education in rural areas over a decade ago. On completion of the project in 1986, over 400,000 peasants had attended video courses lasting from 5-20 days. The courses included rural health, family planning, reforestation, agriculture, animal husbandry, housing, nutrition, and water sanitation. There were 125 course packages made and 1,260 video programs from 10-18 minutes in length. There were 780 additional video programs created on human resource development, socioeconomic diagnostics and culture. 160 specialists were trained to produce audiovisual materials and run the programs. Also, 70 trainers from other countries were trained. The results showed many used the training in practical applications. To promote rural development 2 things are needed , capital and physical inputs, such as equipment, fertilizers, pesticides, etc. The video project provided peasants an additional input that would help them manage the financial and physical inputs more efficiently. Video was used because many farmers are illiterate or speak a language different from the official one. Printed guides that contained many illustrations and few words served as memory aids and group discussions reinforced practical learning. By seeing, hearing, and doing, the training was effective. There were 46% women which made fertility and family planning subjects more easily communicated. The production of teaching modules included field investigations, academic research, field recording, tape editing, and experimental application in the field. An agreement with the peasants was initiated before a course began to help insure full participation and to also make sure resources were available to use the knowledge gained. The courses were limited to 30 and the cost per participant was $34 per course.

Scale model solar systems have been used for centuries to help educate young students and the public about the vastness of space and the relative sizes of objects. We have adapted the classic scale model solar system activity into a student-driven project for an undergraduate general education astronomy course at the University of Arizona. Students are challenged to construct and use their three dimensional models to demonstrate an understanding of numerous concepts in planetary science, including: 1) planetary obliquities, eccentricities, inclinations; 2) phases and eclipses; 3) planetary transits; 4) asteroid sizes, numbers, and distributions; 5) giant planet satellite and ring systems; 6) the Pluto system and Kuiper belt; 7) the extent of space travel by humans and robotic spacecraft; 8) the diversity of extrasolar planetary systems. Secondary objectives of the project allow students to develop better spatial reasoning skills and gain familiarity with technology such as Excel formulas, smart-phone photography, and audio/video editing.During our presentation we will distribute a formal description of the project and discuss our expectations of the students as well as present selected highlights from preliminary submissions.

To what extent do joint attention, imitation, and object play behaviors in infancy predict later communication and intellectual functioning in ASD?

PubMed

Poon, Kenneth K; Watson, Linda R; Baranek, Grace T; Poe, Michele D

2012-06-01

The extent to which early social communication behaviors predict later communication and intellectual outcomes was investigated via retrospective video analysis. Joint attention, imitation, and complex object play behaviors were coded from edited home videos featuring scenes of 29 children with ASD at 9-12 and/or 15-18 months. A quantitative interval recording of behavior and a qualitative rating of the developmental level were applied. Social communication behaviors increased between 9-12 and 15-18 months. Their mean level during infancy, but not the rate of change, predicted both Vineland Communication scores and intellectual functioning at 3-7 years. The two methods of measurement yielded similar results. Thus, early social communicative behaviors may play pivotal roles in the development of subsequent communication and intellectual functioning.

Nucleic acid editing holds promise for treating genetic disease, particularly at the RNA level, where disease-relevant sequences can be rescued to yield functional protein products. Type VI CRISPR-Cas systems contain the programmable single-effector RNA-guided ribonuclease Cas13. We profiled type VI systems in order to engineer a Cas13 ortholog capable of robust knockdown and demonstrated RNA editing by using catalytically inactive Cas13 (dCas13) to direct adenosine-to-inosine deaminase activity by ADAR2 (adenosine deaminase acting on RNA type 2) to transcripts in mammalian cells. This system, referred to as RNA Editing for Programmable A to I Replacement (REPAIR), which has no strict sequence constraints, can be used to edit full-length transcripts containing pathogenic mutations. We further engineered this system to create a high-specificity variant and minimized the system to facilitate viral delivery. REPAIR presents a promising RNA-editing platform with broad applicability for research, therapeutics, and biotechnology. Copyright © 2017, American Association for the Advancement of Science.

Primordial germ cell-mediated transgenesis and genome editing in birds.

PubMed

Han, Jae Yong; Park, Young Hyun

2018-01-01

Transgenesis and genome editing in birds are based on a unique germline transmission system using primordial germ cells (PGCs), which is quite different from the mammalian transgenic and genome editing system. PGCs are progenitor cells of gametes that can deliver genetic information to the next generation. Since avian PGCs were first discovered in nineteenth century, there have been numerous efforts to reveal their origin, specification, and unique migration pattern, and to improve germline transmission efficiency. Recent advances in the isolation and in vitro culture of avian PGCs with genetic manipulation and genome editing tools enable the development of valuable avian models that were unavailable before. However, many challenges remain in the production of transgenic and genome-edited birds, including the precise control of germline transmission, introduction of exogenous genes, and genome editing in PGCs. Therefore, establishing reliable germline-competent PGCs and applying precise genome editing systems are critical current issues in the production of avian models. Here, we introduce a historical overview of avian PGCs and their application, including improved techniques and methodologies in the production of transgenic and genome-edited birds, and we discuss the future potential applications of transgenic and genome-edited birds to provide opportunities and benefits for humans.

Error image aware content restoration

Choi, Sungwoo; Lee, Moonsik; Jung, Byunghee

2015-12-01

As the resolution of TV significantly increased, content consumers have become increasingly sensitive to the subtlest defect in TV contents. This rising standard in quality demanded by consumers has posed a new challenge in today's context where the tape-based process has transitioned to the file-based process: the transition necessitated digitalizing old archives, a process which inevitably produces errors such as disordered pixel blocks, scattered white noise, or totally missing pixels. Unsurprisingly, detecting and fixing such errors require a substantial amount of time and human labor to meet the standard demanded by today's consumers. In this paper, we introduce a novel, automated error restoration algorithm which can be applied to different types of classic errors by utilizing adjacent images while preserving the undamaged parts of an error image as much as possible. We tested our method to error images detected from our quality check system in KBS(Korean Broadcasting System) video archive. We are also implementing the algorithm as a plugin of well-known NLE(Non-linear editing system), which is a familiar tool for quality control agent.

Gene editing in clinical isolates of Candida parapsilosis using CRISPR/Cas9.

PubMed

Lombardi, Lisa; Turner, Siobhán A; Zhao, Fang; Butler, Geraldine

2017-08-14

Candida parapsilosis is one of the most common causes of candidiasis, particularly in the very young and the very old. Studies of gene function are limited by the lack of a sexual cycle, the diploid genome, and a paucity of molecular tools. We describe here the development of a plasmid-based CRISPR-Cas9 system for gene editing in C. parapsilosis. A major advantage of the system is that it can be used in any genetic background, which we showed by editing genes in 20 different isolates. Gene editing is carried out in a single transformation step. The CAS9 gene is expressed only when the plasmid is present, and it can be removed easily from transformed strains. There is theoretically no limit to the number of genes that can be edited in any strain. Gene editing is increased by homology-directed repair in the presence of a repair template. Editing by non-homologous end joining (NHEJ) also occurs in some genetic backgrounds. Finally, we used the system to introduce unique tags at edited sites.

The AJCC 8th Edition Staging System for Soft Tissue Sarcoma of the Extremities or Trunk: A Cohort Study of the SEER Database.

PubMed

Cates, Justin M M

2018-02-01

Background: The AJCC recently published the 8th edition of its cancer staging system. Significant changes were made to the staging algorithm for soft tissue sarcoma (STS) of the extremities or trunk, including the addition of 2 additional T (size) classifications in lieu of tumor depth and grouping lymph node metastasis (LNM) with distant metastasis as stage IV disease. Whether these changes improve staging system performance is questionable. Patients and Methods: This retrospective cohort analysis of 21,396 adult patients with STS of the extremity or trunk in the SEER database compares the AJCC 8th edition staging system with the 7th edition and a newly proposed staging algorithm using a variety of statistical techniques. The effect of tumor size on disease-specific survival was assessed by flexible, nonlinear Cox proportional hazard regression using restricted cubic splines and fractional polynomials. Results: The slope of covariate-adjusted log hazards for sarcoma-specific survival decreases for tumors >8 cm in greatest dimension, limiting prognostic information contributed by the new T4 classification in the AJCC 8th edition. Anatomic depth independently provides significant prognostic information. LNM is not equivalent to distant, non-nodal metastasis. Based on these findings, an alternative staging system is proposed and demonstrated to outperform both AJCC staging schemes. The analyses presented also disclose no evidence of improved clinical performance of the 8th edition compared with the previous edition. Conclusions: The AJCC 8th edition staging system for STS is no better than the previous 7th edition. Instead, a proposed staging system based on histologic grade, tumor size, and anatomic depth shows significantly higher predictive accuracy, with higher model concordance than either AJCC staging system. Changes to existing staging systems should improve the performance of prognostic models. Until such improvements are documented, AJCC committees should refrain from modifying established staging schemes. Copyright © 2018 by the National Comprehensive Cancer Network.

The present study aims to compare the 7(th) and the proposed 8(th) edition of the AJCC/UICC TNM staging system for NSCLC in a cohort of patients from a single institution. A total of 408 patients with NSCLC who underwent radical surgery were analyzed retrospectively. Survivals were analyzed using the Kaplan -Meier method and were compared using the log-rank test. Multivariate analysis was performed by the Cox proportional hazard model. The Akaike information criterion (AIC) and C-index were applied to compare the two prognostic systems with different numbers of stages. The 7(th) AJCC T categories, the proposed 8(th) AJCC T categories, N categories, visceral pleural invasion, and vessel invasion were found to have statistically significant associations with disease-free survival (DFS) on univariate analysis. In the 7(th) edition staging system as well as in the proposed 8(th) edition, T categories, N categories, and pleural invasion were independent factors for DFS on multivariate analysis. The AIC value was smaller for the 8(th) edition compared to the 7(th) edition staging system. The C-index value was larger for the 8(th) edition compared to the 7(th) edition staging system. Based on the data from our single center, the proposed 8(th) AJCC T classification seems to be superior to the 7(th) AJCC T classification in terms of DFS for patients with NSCLC underwent radical surgery.

Estimation and detection information trade-off for x-ray system optimization

Cushing, Johnathan B.; Clarkson, Eric W.; Mandava, Sagar; Bilgin, Ali

2016-05-01

X-ray Computed Tomography (CT) systems perform complex imaging tasks to detect and estimate system parameters, such as a baggage imaging system performing threat detection and generating reconstructions. This leads to a desire to optimize both the detection and estimation performance of a system, but most metrics only focus on one of these aspects. When making design choices there is a need for a concise metric which considers both detection and estimation information parameters, and then provides the user with the collection of possible optimal outcomes. In this paper a graphical analysis of Estimation and Detection Information Trade-off (EDIT) will be explored. EDIT produces curves which allow for a decision to be made for system optimization based on design constraints and costs associated with estimation and detection. EDIT analyzes the system in the estimation information and detection information space where the user is free to pick their own method of calculating these measures. The user of EDIT can choose any desired figure of merit for detection information and estimation information then the EDIT curves will provide the collection of optimal outcomes. The paper will first look at two methods of creating EDIT curves. These curves can be calculated using a wide variety of systems and finding the optimal system by maximizing a figure of merit. EDIT could also be found as an upper bound of the information from a collection of system. These two methods allow for the user to choose a method of calculation which best fits the constraints of their actual system.

Targeted genome editing technology is an important tool to study the function of genes and to modify organisms at the genetic level. Recently, CRISPR-Cas (clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins) system has emerged as an efficient tool for specific genome editing in animals and plants. CRISPR-Cas system uses CRISPR-associated endonuclease and a guide RNA to generate double-strand breaks at the target DNA site, subsequently leading to genetic modifications. CRISPR-Cas system has received widespread attention for manipulating the genomes with simple, easy and high specificity. This review summarizes recent advances of diverse applications of the CRISPR-Cas toolkit in plant research and crop breeding, including expanding the range of genome editing, precise editing of a target base, and efficient DNA-free genome editing technology. This review also discusses the potential challenges and application prospect in the future, and provides a useful reference for researchers who are interested in this field.

With the development and improvement of CRISPR/Cas9 system in genomic editing technology, the system has been applied to the prevention and control of animal viral infectious diseases, which has made considerable achievements. It has also been applied to the study of highly efficient gene targeting editing in plant virus genomes. The CRISPR/Cas9-mediated targeted gene modification has not only achieved the genome editing of plant DNA virus, but also showed the genome editing potential of plant RNA virus. In addition, the CRISPR/Cas9 system functions at the gene transcriptional and post-transcriptional level, indicating that the system could regulate the replication of plant viruses through different ways. Compared with other plant viral disease control strategies, this system is more accurate in genome editing, more stable in gene expression regulation, and has broader spectrum of resistance to virus disease. In this review, we summarized the advantages, main problems and development tendency of CRISPR/cas9 system in breeding of new antiviral plant germplasms.

Surface motion capture (SurfCap) of actor performance from multiple view video provides reconstruction of the natural nonrigid deformation of skin and clothing. This paper introduces techniques for interactive animation control of SurfCap sequences which allow the flexibility in editing and interactive manipulation associated with existing tools for animation from skeletal motion capture (MoCap). Laplacian mesh editing is extended using a basis model learned from SurfCap sequences to constrain the surface shape to reproduce natural deformation. Three novel approaches for animation control of SurfCap sequences, which exploit the constrained Laplacian mesh editing, are introduced: 1) space–time editing for interactive sequence manipulation; 2) skeleton-driven animation to achieve natural nonrigid surface deformation; and 3) hybrid combination of skeletal MoCap driven and SurfCap sequence to extend the range of movement. These approaches are combined with high-level parametric control of SurfCap sequences in a hybrid surface and skeleton-driven animation control framework to achieve natural surface deformation with an extended range of movement by exploiting existing MoCap archives. Evaluation of each approach and the integrated animation framework are presented on real SurfCap sequences for actors performing multiple motions with a variety of clothing styles. Results demonstrate that these techniques enable flexible control for interactive animation with the natural nonrigid surface dynamics of the captured performance and provide a powerful tool to extend current SurfCap databases by incorporating new motions from MoCap sequences.

With the increasing of business requirement of urban planning bureau, co-edit function is needed urgently, however conventional GIS are not support this. In order to overcome this limitation, a new kind urban 1planning management system with co-edit function is needed. Such a system called PM2006 has been used in Suzhou Urban Planning Bureau. PM2006 is introduced in this paper. In this paper, four main issues of Co-edit system--consistency, responsiveness time, data recoverability and unconstrained operation--were discussed. And for these four questions, resolutions were put forward in paper. To resolve these problems of co-edit GIS system, a data model called FGDB (File and ESRI GeoDatabase) that is mixture architecture of File and ESRI Geodatabase was introduced here. The main components of FGDB data model are ESRI versioned Geodatabase and replicated architecture. With FGDB, client responsiveness, spatial data recoverability and unconstrained operation were overcome. In last of paper, MapServer, the co-edit map server module, is presented. Main functions of MapServer are operation serialization and spatial data replication between file and versioned data.

The aim of this study was to examine whether behavioral tendencies commonly related to addictive behaviors are also related to problematic computer and video game playing in adolescents. The study of attentional bias and response inhibition, characteristic for addictive disorders, is relevant to the ongoing discussion on whether problematic gaming should be classified as an addictive disorder. We tested the relation between self-reported levels of problem gaming and two behavioral domains: attentional bias and response inhibition. Ninety-two male adolescents performed two attentional bias tasks (addiction-Stroop, dot-probe) and a behavioral inhibition task (go/no-go). Self-reported problem gaming was measured by the game addiction scale, based on the Diagnostic and Statistical Manual of Mental Disorders-fourth edition criteria for pathological gambling and time spent on computer and/or video games. Male adolescents with higher levels of self-reported problem gaming displayed signs of error-related attentional bias to game cues. Higher levels of problem gaming were also related to more errors on response inhibition, but only when game cues were presented. These findings are in line with the findings of attentional bias reported in clinically recognized addictive disorders, such as substance dependence and pathological gambling, and contribute to the discussion on the proposed concept of "Addiction and Related Disorders" (which may include non-substance-related addictive behaviors) in the Diagnostic and Statistical Manual of Mental Disorders-fourth edition.

2005-04-01

Display and interpretation of multi dimensional data obtained from the combination of 3D data acquired from different modalities (such as PET-CT) require complex software tools allowing the user to navigate and modify the different image parameters. With faster scanners it is now possible to acquire dynamic images of a beating heart or the transit of a contrast agent adding a fifth dimension to the data. We developed a DICOM-compliant software for real time navigation in very large sets of 5 dimensional data based on an intuitive multidimensional jog-wheel widely used by the video-editing industry. The software, provided under open source licensing, allows interactive, single-handed, navigation through 3D images while adjusting blending of image modalities, image contrast and intensity and the rate of cine display of dynamic images. In this study we focused our effort on the user interface and means for interactively navigating in these large data sets while easily and rapidly changing multiple parameters such as image position, contrast, intensity, blending of colors, magnification etc. Conventional mouse-driven user interface requiring the user to manipulate cursors and sliders on the screen are too cumbersome and slow. We evaluated several hardware devices and identified a category of multipurpose jogwheel device that is used in the video-editing industry that is particularly suitable for rapidly navigating in five dimensions while adjusting several display parameters interactively. The application of this tool will be demonstrated in cardiac PET-CT imaging and functional cardiac MRI studies.

The hydrolytic deamination of adenosine to inosine (A-to-I editing) in precursor mRNA induces variable gene products at the post-transcription level. How and to what extent A-to-I RNA editing diversifies transcriptome is not fully characterized in the evolution, and very little is known about the selective constraints that drive the evolution of RNA editing events. Here we present a study on A-to-I RNA editing, by generating a global profile of A-to-I editing for a phylogeny of seven Drosophila species, a model system spanning an evolutionary timeframe of approximately 45 million years. Of totally 9281 editing events identified, 5150 (55.5%) are located in the coding sequences (CDS) of 2734 genes. Phylogenetic analysis places these genes into 1,526 homologous families, about 5% of total gene families in the fly lineages. Based on conservation of the editing sites, the editing events in CDS are categorized into three distinct types, representing events on singleton genes (type I), and events not conserved (type II) or conserved (type III) within multi-gene families. While both type I and II events are subject to purifying selection, notably type III events are positively selected, and highly enriched in the components and functions of the nervous system. The tissue profiles are documented for three editing types, and their critical roles are further implicated by their shifting patterns during holometabolous development and in post-mating response. In conclusion, three A-to-I RNA editing types are found to have distinct evolutionary dynamics. It appears that nervous system functions are mainly tested to determine if an A-to-I editing is beneficial for an organism. The coding plasticity enabled by A-to-I editing creates a new class of binary variations, which is a superior alternative to maintain heterozygosity of expressed genes in a diploid mating system.

A robust TALENs system for highly efficient mammalian genome editing.

PubMed

Feng, Yuanxi; Zhang, Siliang; Huang, Xin

2014-01-10

Recently, transcription activator-like effector nucleases (TALENs) have emerged as a highly effective tool for genomic editing. A pair of TALENs binds to two DNA recognition sites separated by a spacer sequence, and the dimerized FokI nucleases at the C terminal then cleave DNA in the spacer. Because of its modular design and capacity to precisely target almost any desired genomic locus, TALEN is a technology that can revolutionize the entire biomedical research field. Currently, for genomic editing in cultured cells, two plasmids encoding a pair of TALENs are co-transfected, followed by limited dilution to isolate cell colonies with the intended genomic manipulation. However, uncertain transfection efficiency becomes a bottleneck, especially in hard-to-transfect cells, reducing the overall efficiency of genome editing. We have developed a robust TALENs system in which each TALEN plasmid also encodes a fluorescence protein. Thus, cells transfected with both TALEN plasmids, a prerequisite for genomic editing, can be isolated by fluorescence-activated cell sorting. Our improved TALENs system can be applied to all cultured cells to achieve highly efficient genomic editing. Furthermore, an optimized procedure for genomic editing using TALENs is also presented. We expect our system to be widely adopted by the scientific community.

CRISPR/Cas9 system can precisely edit genomic sequence and effectively create knockout mutations in T0 generation watermelon plants. Genome editing offers great advantage to reveal gene function and generate agronomically important mutations to crops. Recently, RNA-guided genome editing system using the type II clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein 9 (Cas9) has been applied to several plant species, achieving successful targeted mutagenesis. Here, we report the genome of watermelon, an important fruit crop, can also be precisely edited by CRISPR/Cas9 system. ClPDS, phytoene desaturase in watermelon, was selected as the target gene because its mutant bears evident albino phenotype. CRISPR/Cas9 system performed genome editing, such as insertions or deletions at the expected position, in transfected watermelon protoplast cells. More importantly, all transgenic watermelon plants harbored ClPDS mutations and showed clear or mosaic albino phenotype, indicating that CRISPR/Cas9 system has technically 100% of genome editing efficiency in transgenic watermelon lines. Furthermore, there were very likely no off-target mutations, indicated by examining regions that were highly homologous to sgRNA sequences. Our results show that CRISPR/Cas9 system is a powerful tool to effectively create knockout mutations in watermelon.

Google started an opensource project, entitled the WebM Project, in 2010 to develop royaltyfree video codecs for the web. The present generation codec developed in the WebM project called VP9 was finalized in mid2013 and is currently being served extensively by YouTube, resulting in billions of views per day. Even though adoption of VP9 outside Google is still in its infancy, the WebM project has already embarked on an ambitious project to develop a next edition codec VP10 that achieves at least a generational bitrate reduction over the current generation codec VP9. Although the project is still in early stages, a set of new experimental coding tools have already been added to baseline VP9 to achieve modest coding gains over a large enough test set. This paper provides a technical overview of these coding tools.

The use of web-based portals, while increasing in popularity in the fields of medicine and research, are rarely reported on in community-based rehabilitation programs. A program within the Pennsylvania Office of Vocational Rehabilitation’s Hiram G. Andrews Center, the Cognitive Skills Enhancement Program (CSEP), sought to enhance organization of program and participant information and communication between part- and full-time employees, supervisors and consultants. A telerehabilitation system was developed consisting of (1) a web-based portal to support a variety of clinical activities, and (2) the Versatile Integrated System for Telerehabilitation (VISYTER) video-conferencing system to support the collaboration and delivery of rehabilitation services remotely. This descriptive evaluation examines the usability of the telerehabilitation system incorporating both the portal and VISYTER. Telerehabilitation system users include CSEP staff members from three geographical locations and employed by two institutions. The IBM After-Scenario Questionnaire (ASQ) and Post-Study System Usability Questionnaire (PSSUQ), the Telehealth Usability Questionnaire (TUQ), and two demographic surveys were administered to gather both objective and subjective information. Results showed generally high levels of usability. Users commented that the telerehabilitation system improved communication, increased access to information, improved speed of completing tasks, and had an appealing interface. Areas where users would like to see improvements, including ease of accessing/editing documents and searching for information, are discussed. PMID:25945193

Genome editing systems based on site-specific nucleases became very popular for genome editing in modern bioengineering. Human pluripotent stem cells provide a unique platform for genes function study, disease modeling, and drugs testing. Consequently, technology for fast, accurate and well controlled genome manipulation is required. CRISPR/Cas (clustered regularly interspaced short palindromic repeat/CRISPR-associated) system could be employed for these purposes. This system is based on site-specific programmable nuclease Cas9. Numerous advantages of the CRISPR/Cas system and its successful application to human stem cells provide wide opportunities for genome therapy and regeneration medicine. In this publication, we describe and compare the main genome editing systems based on site-specific programmable nucleases and discuss opportunities and perspectives of the CRISPR/Cas system for application to pluripotent stem cells.

Marín Arraiza, Paloma; Plank, Margret; Löwe, Peter

2016-04-01

Scientific audiovisual media such as videos of research, interactive displays or computer animations has become an important part of scientific communication and education. Dynamic phenomena can be described better by audiovisual media than by words and pictures. For this reason, scientific videos help us to understand and discuss environmental phenomena more efficiently. Moreover, the creation of scientific videos is easier than ever, thanks to mobile devices and open source editing software. Video-clips, webinars or even the interactive part of a PICO are formats of scientific audiovisual media used in the Geosciences. This type of media translates the location-referenced Science Communication such as environmental interpretation into computed-based Science Communication. A new way of Science Communication is video abstracting. A video abstract is a three- to five-minute video statement that provides background information about a research paper. It also gives authors the opportunity to present their research activities to a wider audience. Since this kind of media have become an important part of scientific communication there is a need for reliable infrastructures which are capable of managing the digital assets researchers generate. Using the reference of the usecase of video abstracts this paper gives an overview over the activities by the German National Library of Science and Technology (TIB) regarding publishing and linking audiovisual media in a scientifically sound way. The German National Library of Science and Technology (TIB) in cooperation with the Hasso Plattner Institute (HPI) developed a web-based portal (av.tib.eu) that optimises access to scientific videos in the fields of science and technology. Videos from the realms of science and technology can easily be uploaded onto the TIB|AV Portal. Within a short period of time the videos are assigned a digital object identifier (DOI). This enables them to be referenced, cited, and linked (e.g. to the relevant article or further supplement materials). By using media fragment identifiers not only the whole video can be cited, but also individual parts of it. Doing so, users are also likely to find high-quality related content (for instance, a video abstract and the corresponding article or an expedition documentary and its field notebook). Based on automatic analysis of speech, images and texts within the videos a large amount of metadata associated with the segments of the video is automatically generated. These metadata enhance the searchability of the video and make it easier to retrieve and interlink meaningful parts of the video. This new and reliable library-driven infrastructure allow all different types of data be discoverable, accessible, citable, freely reusable, and interlinked. Therefore, it simplifies Science Communication

Online experimentation is emerging as a new methodology within classical data acquisition in psychology. It allows for easy, fast, broad, and cheap data conduction from the comfort of people’s homes. To add another method to the array of available tools, here we used recent developments in web technology to investigate the technical feasibility of online HyperText Markup Language-5/JavaScript-based video data recording. We employed a preferential looking task with children between 4 and 24 months. Parents and their children participated from home through a three-stage process: First, interested adults registered and took pictures through a webcam-based photo application. In the second step, we edited the pictures and integrated them into the design. Lastly, participants returned to the website and the video data acquisition took place through their webcam. In sum, we were able to create and employ the video recording application with participants as young as 4 months old. Quality-wise, no participant had to be removed due to the framerate or quality of videos and only 7% of data was excluded due to behavioral factors (lack of concentration). Results-wise, interrater reliability of rated looking side (left/right) showed a high agreement between raters, Fleiss’ Kappa, κ = 0.97, which can be translated to sufficient data quality for further analyses. With regard to on-/off-screen attention attribution, we found that children lost interest after about 10 s after trial onset using a static image presentation or 60 s total experimental time. Taken together, we were able to show that online video data recording is possible and viable for developmental psychology and beyond. PMID:28955284

The aim of this study was to compare selected parameters of two swallow evaluations: fiberoptic endoscopic evaluation of swallowing (FEES) and the modified barium swallow (MBS) study. This was a cross-sectional, descriptive study. Fifty-five clinicians were asked to watch video recordings of swallow evaluations of 2 patients that were done using fluoroscopy and endoscopy simultaneously. In a randomized order, clinicians viewed 4 edited videos from simultaneous evaluations: the FEES and MBS videos of patient 1 and 2 each taking one swallow of 5 mL applesauce. Clinicians filled out a questionnaire that asked (1) which anatomical sites they could visualize on each video, (2) where they saw pharyngeal residue after a swallow, (3) their overall clinical impression of the pharyngeal residue, and (4) their opinions of the evaluation styles. Clinicians reported a significant difference in the visualization of anatomical sites, 11 of the 15 sites were reported as better-visualized on the FEES than on the MBS video (p < 0.05). Clinicians also rated residue to be present in more locations on the FEES than on the MBS. Clinicians' overall impressions of the severity of residue on the same exact swallow were significantly different depending on the evaluation type (FEES vs. MBS for patient 1 χ(2) = 20.05, p < 0.0001; patient 2 χ(2) = 7.52, p = 0.006), with FEES videos rated more severely. FEES advantages were: more visualization of pharyngeal and laryngeal swallowing anatomy and residue. However, as a result, clinicians provided more severe impressions of residue amount on FEES. On one hand, this suggests that FEES is a more sensitive tool than MBS studies, but on the other hand, clinicians might provide more severe interpretations on FEES.

Technical 'hands-on' training workshops are designed to bring together scientists, technicians, and program managers from universities, government agencies, and the private sector to discuss methods used and advances made in instrumentation and data analysis. Through classroom lectures and discussions combined with a field-day component, hands-on workshop participants get a 'full life cycle' perspective from instrumentation concepts and deployment to data analysis. Using film to document this process is becoming increasingly more popular, allowing scientists to add a story-telling component to their research. With the availability of high-quality and low priced professional video equipment and editing software, scientists are becoming digital storytellers. The science video developed from the 'hands-on' workshop, Optical Water Quality Sensors for Nutrients: Concepts, Deployment, and Analysis, encapsulates the objectives of technical training workshops for participants. Through the use of still photography, video, interviews, and sound, the short video, An Introduction to CUAHSI's Hands-on Workshops, produced by a co-instructor of the workshop acts as a multi-purpose tool. The 10-minute piece provides an overview of workshop field day activities and works to bridge the gap between classroom learning, instrumentation application and data analysis. CUAHSI 'hands-on' technical workshops have been collaboratively executed with faculty from several universities and with the U.S. Geological Survey. The video developed was designed to attract new participants to these professional development workshops, to stimulate a connection with the environment, to act as a workshop legacy resource, and also serve as a guide for prospective hands-on workshop organizers. The effective use of film and short videos in marketing scientific programs, such as technical trainings, allows scientists to visually demonstrate the technologies currently being employed and to provide a more intriguing perspective on scientific research.

Recently, RNA-guided genome editing using the type II clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein (Cas) system has been applied to edit the plant genome in several herbaceous plant species. However, it remains unknown whether this system can be used for genome editing in woody plants. In this study, we describe the genome editing and targeted gene mutation in a woody species, Populus tomentosa Carr. via the CRISPR/Cas9 system. Four guide RNAs (gRNAs) were designed to target with distinct poplar genomic sites of the phytoene desaturase gene 8 (PtoPDS) which are followed by the protospacer-adjacent motif (PAM). After Agrobacterium-mediated transformation, obvious albino phenotype was observed in transgenic poplar plants. By analyzing the RNA-guided genome-editing events, 30 out of 59 PCR clones were homozygous mutants, 2 out of 59 were heterozygous mutants and the mutation efficiency at these target sites was estimated to be 51.7%. Our data demonstrate that the Cas9/sgRNA system can be exploited to precisely edit genomic sequence and effectively create knockout mutations in woody plants. PMID:26193631

Evidence on how the pace of television and film editing affects children's behaviour and attention is inconclusive. We examined whether a fast-paced film affected how preschool-aged children interacted with toys. The study comprised 70 children (36 girls) aged two to four-and-a-half years who attended preschools in Essex, United Kingdom. The children were paired up and tested with either a fast- or a slow-paced film of a narrator reading a children's story. The fast-paced version had 102 camera cuts and 16 still images, and the slow-paced version had 22 camera cuts and four still images. Each dyad took part in two video-recorded free-play sessions, before and after they watched one of the specially edited four-minute films. The number of toys the children played with before and after the film sessions was recorded. Before they watched the films, the children's behaviour did not differ between the groups. However, after watching the film, the children in the fast-paced group shifted their attention between toys more frequently than the children who watched the slow-paced film. Even a brief exposure to differently paced films had an immediate effect on how the children interacted with their toys. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

2014-12-01

With recent technological advances, the barriers to filmmaking have been lowered, and it is now possible to record and edit video footage with a smartphone or a handheld camera and free software. Students accustomed to documenting their every-day experiences for multimedia-rich social networking sites feel excited and creatively inspired when asked to take on ownership of more complex video projects. With a small amount of guidance on shooting primary and secondary footage and an overview of basic interview skills, students are self-motivated to identify the learning themes with which they resonate most strongly and record their footage in a way that is true to their own experience. The South Central Climate Science Center (SC-CSC) is one of eight regional centers formed by the U.S. Department of the Interior in order to provide decision makers with the science, tools, and information they need to address the impacts of climate variability and change on their areas of responsibility. An important component of this mission is to innovate in the areas of translational science and science communication. This presentation will highlight how the SC-CSC used student-driven video projects to document our Early Career Researcher Workshop and our Undergraduate Internship for Underrepresented Minorities. These projects equipped the students with critical thinking and project management skills, while also providing a finished product that the SC-CSC can use for future outreach purposes.

To assess and evaluate the prognostic value of the 7(th) edition of the Union for International Cancer Control-American Joint Committee on Cancer (UICC-AJCC) tumor, node, metastasis (TNM) staging system for Chinese patients with esophageal cancer in comparison with the 6(th) edition. A retrospective review was performed on 766 consecutive esophageal cancer patients treated with esophagectomy between 2008 and 2012. Patients were staged according to the 6(th) and 7(th) editions for esophageal cancer respectively. Survival was calculated by the Kaplan-Meier method, and multivariate analysis was performed using Cox regression model. Overall 3-year survival rate was 59.5%. There were significant differences in 3-year survival rates among T stages both according to the 6(th) edition and the 7(th) edition (P<0.001). According to the 7(th) edition, the 3-year survival rates of N0 (75.4%), N1 (65.2%), N2 (39.7%) and N3 (27.3%) patients were significant differences (P<0.001). Kaplan-Meier curve revealed a good discriminatory ability from stage I to IV, except for stage IB, IIA and IIB in the 7(th) edition staging system. Based on the 7(th) edition, the degree of differentiation, tumor length and tumor location were not independent prognostic factors on multivariate analysis. The multivariate analyses suggested that pT-, pN-, pTNM-category were all the independent prognostic factors based on the 6(th) and 7(th) edition staging system. The 7(th) edition of AJCC TNM staging system of esophageal cancer should discriminate pT2-3N0M0 (stage IB, IIA and IIB) better when considering the esophageal squamous cell cancer patients. Therefore, to improve and optimize the AJCC TNM classification for Chinese patients with esophageal cancer, more considerations about the value of tumor grade and tumor location in pT2-3N0M0 esophageal squamous cell cancer should be taken in the next new TNM staging system.

Cremer, Markus; Cook, Randall

2009-02-01

Over recent years user-generated content has become ubiquitously available and an attractive entertainment source for millions of end-users. Particularly for larger events, where many people use their devices to capture the action, a great number of short video clips are made available through appropriate web services. The objective of this presentation is to describe a way to combine these clips by analyzing them, and automatically reconstruct the time line in which the individual video clips were captured. This will enable people to easily create a compelling multimedia experience by leveraging multiple clips taken by different users from different angles, and across different time spans. The user will be able to shift into the role of a movie director mastering a multi-camera recording of the event. To achieve this goal, the audio portion of the video clips is analyzed, and waveform characteristics are computed with high temporal granularity in order to facilitate precise time alignment and overlap computation of the user-generated clips. Special care has to be given not only to the robustness of the selected audio features against ambient noise and various distortions, but also to the matching algorithm used to align the user-generated clips properly.

The effects of live music groups versus an educational children's television program on the emergent literacy of young children.

Research suggests that music is beneficial in teaching both social and academic skills to young children. The purpose of this study was to examine the effects of a music therapy program designed to teach reading skills versus the "Between the Lions" television program on the early literacy behaviors of Kindergarten children from a low socioeconomic background. Subjects (n = 86) were children, aged 5-7 years, enrolled in one of four different Kindergarten classes at a public elementary school in Northwest Florida. Each class was assigned one of four treatment conditions: Music/Video (sequential presentation of each condition), Music-Only, Video-Only, and no contact Control group. Growth in early literacy skills was measured using the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) and 3 subtests of the Test of Early reading Ability-3rd edition (TERA-3). Teachers' perceptions of classroom literacy behaviors were measured using a pre and poststudy survey. This study also compared on- and off-task behavior of students during video versus music conditions. Results of the 7 subtests measuring early literacy were varied. The Music/Video and Music-Only groups achieved the highest increases in mean scores from pre to posttest on 4 of the 7 subtests. Students in the Video-Only group scored significantly better on the phonemic segmentation portion of the DIBELS than peers in the Music/Video condition. Furthermore, strong correlations were found between the Letter Naming, Initial Sounds Fluency tests, and total raw score of the TERA-3 tests for both pre and posttesting. Additionally, graphic analysis of mean off-task behavior per session indicated that students were more off-task during both video conditions (video alone and video portion of Music/Video condition) than during the music conditions. Off-task behavior was consistently lower during music sessions for the duration of the study. This study confirmed that music increases the on-task behavior of students. Additionally, the combination of music and video enrichment showed gains in 4 of the 8 tests used to measure students' progress. This pattern supports the need for further investigation regarding benefits of enrichment programs specifically designed to enhance curricula for students from low socioeconomic backgrounds, particularly programs that incorporate music activities.

Controlled flexibility in technical editing - The levels-of-edit concept at JPL

NASA Technical Reports Server (NTRS)

Buehler, M. F.

1977-01-01

The levels-of-edit concept, which can be used to specify the amount of editorial effort involved in the preparation of a manuscript for publication, is discussed. Nine types of editing are identified and described. These include coordination edit (preparing estimates, gathering cost data, monitoring production processes), policy edit, integrity edit (making sure that parts of a publication match in a physical or numerical sense), screening edit (ensuring that the quality of camera-ready copy is sufficient for external publication), copy clarification edit, format edit, mechanical style edit, language edit, and substantive edit (reviewing the manuscript for content coherence, emphasis, subordination and parallelism). These functions are grouped into five levels of edit. An edit-level number is assigned to each manuscript, providing a quantitative and qualitative indicator of the editing to be done which is clearly understood by authors, managers, and editors alike. In addition, clear boundaries are drawn between normal and extraordinary editing tasks. Individual organizations will group various edits in different ways to reflect their needs and priorities; the essential element of the system is unambiguous definition and coding of the types and amount of work to be done.

The recently published AJCC Esophageal Cancer Staging System, 8(th) Edition will be implemented on Januray 1, 2018, which was developed by Worldwide Esophageal Cancer Collaboration based on 22 654 esophageal cancer patients from 33 worldwide centers. The definition of T, N, M, G stage and regional lymph nodes were optimized in the 8(th) edition. And the new "2 cm" principle has simplified the definition for the cancer of esophagogastric junction. In addition to pathologic staging, the 8(th) edition also provided clinical staging and pathologic staging after neoadjuvant therapy, making the new esophageal cancer staging system more practicable and reasonable.

Design, dissemination, and evaluation of an advanced communication elective at seven U.S. medical schools.

Mauksch, Larry; Farber, Stuart; Greer, H Thomas

2013-06-01

To test educational methods that continue communication training into the fourth year of medical school. The authors disseminated and evaluated an advanced communication elective in seven U.S. medical schools between 2007 and 2009; a total of 9 faculty and 22 fourth-year students participated. The elective emphasized peer learning, practice with real patients, direct observation, and applications of video technology. The authors used qualitative and quantitative survey methods and video review to evaluate the experience of students and faculty. Students reported that the elective was better than most medical school clerkships they had experienced. Their self-confidence in time management and in the use of nine communication skills improved significantly. The most valued course components were video review, repeated practice with real patients, and peer observation. Analysis of student videos with real patients and in role-plays showed that some skills (e.g., agenda setting, understanding the patient perspective) were more frequently demonstrated than others (e.g., exploring family and cultural values, communication while using the electronic health record). Faculty highly valued this learner-centered model and reported that their self-awareness and communication skills grew as teachers and as clinicians. Learner-centered methods such as peer observation and video review and editing may strengthen communication training and reinforce skills introduced earlier in medical education. The course design may counteract a "hidden curriculum" that devalues respectful interactions with trainees and patients. Future research should assess the impact of course elements on skill retention, attitudes for lifelong learning, and patients' health outcomes.

The 3(rd) English edition of the Japanese classification of the biliary tract cancers (JC) is now available in this journal. The primary aim of this revision is to provide all clinicians and researchers with a common language of cancer staging at an international level. On the other hand, there are several important issues that should be solved for the optimization of the staging system. Revision concepts and major revision points of the 3(rd) English edition of the JC were reviewed. Furthermore, comparing with the 7(th) edition of staging system developed by the Union for International Cancer Control (UICC) and the American Joint Committee on Cancer (AJCC), distinctive points in the JC was discussed. In this edition of the JC, the same stage groupings as those in the UICC/AJCC staging system were basically adopted. T, N, and M categories were also identical in principle with those in the UICC/AJCC staging system, although slight modifications were proposed as the "Japanese rules". As distinctive points, perihilar cholangiocarcinomas and ampullary region carcinomas were clearly defined. Intraepithelial tumor was discriminated from invasive carcinoma at ductal resection margins. Classifications of site-specific surgical margin status remained in this edition. Histological classification was based on that in the former editions of the JC, but adopted some parts of the World Health Organization classification. The JC now share its staging system of the biliary tact carcinomas with the UICC/AJCC staging system. Future validation of the "Japanese rules" could provide important evidence to make globally standardized staging system. © 2015 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

An Efficient, Rapid, and Recyclable System for CRISPR-Mediated Genome Editing in Candida albicans.

PubMed

Nguyen, Namkha; Quail, Morgan M F; Hernday, Aaron D

2017-01-01

Candida albicans is the most common fungal pathogen of humans. Historically, molecular genetic analysis of this important pathogen has been hampered by the lack of stable plasmids or meiotic cell division, limited selectable markers, and inefficient methods for generating gene knockouts. The recent development of clustered regularly interspaced short palindromic repeat(s) (CRISPR)-based tools for use with C. albicans has opened the door to more efficient genome editing; however, previously reported systems have specific limitations. We report the development of an optimized CRISPR-based genome editing system for use with C. albicans . Our system is highly efficient, does not require molecular cloning, does not leave permanent markers in the genome, and supports rapid, precise genome editing in C. albicans . We also demonstrate the utility of our system for generating two independent homozygous gene knockouts in a single transformation and present a method for generating homozygous wild-type gene addbacks at the native locus. Furthermore, each step of our protocol is compatible with high-throughput strain engineering approaches, thus opening the door to the generation of a complete C. albicans gene knockout library. IMPORTANCE Candida albicans is the major fungal pathogen of humans and is the subject of intense biomedical and discovery research. Until recently, the pace of research in this field has been hampered by the lack of efficient methods for genome editing. We report the development of a highly efficient and flexible genome editing system for use with C. albicans . This system improves upon previously published C. albicans CRISPR systems and enables rapid, precise genome editing without the use of permanent markers. This new tool kit promises to expedite the pace of research on this important fungal pathogen.

The closed circuit television (CCTV) system that is onboard the Space Shuttle has the following capabilities: camera, video signal switching and routing unit (VSU); and Space Shuttle video tape recorder. However, this system is inadequate for use with many experiments that require video imaging. In order to assess the state-of-the-art in video technology and data storage systems, a survey was conducted of the High Resolution, High Frame Rate Video Technology (HHVT) products. The performance of the state-of-the-art solid state cameras and image sensors, video recording systems, data transmission devices, and data storage systems versus users' requirements are shown graphically.

The clustered regularly interspaced short palindromic repeats (CRISPR)-associated endonuclease 9 (CRISPR/Cas9) system has emerged as a promising technology for specific genome editing in many species. Here we constructed one vector targeting eight agronomic genes in rice using the CRISPR/Cas9 multiplex genome editing system. By subsequent genetic transformation and DNA sequencing, we found that the eight target genes have high mutation efficiencies in the T 0 generation. Both heterozygous and homozygous mutations of all editing genes were obtained in T 0 plants. In addition, homozygous sextuple, septuple, and octuple mutants were identified. As the abundant genotypes in T 0 transgenic plants, various phenotypes related to the editing genes were observed. The findings demonstrate the potential of the CRISPR/Cas9 system for rapid introduction of genetic diversity during crop breeding.

Applying emerging digital video interface standards to airborne avionics sensor and digital map integrations: benefits outweigh the initial costs

NASA Astrophysics Data System (ADS)

Kuehl, C. Stephen

1996-06-01

Video signal system performance can be compromised in a military aircraft cockpit management system (CMS) with the tailoring of vintage Electronics Industries Association (EIA) RS170 and RS343A video interface standards. Video analog interfaces degrade when induced system noise is present. Further signal degradation has been traditionally associated with signal data conversions between avionics sensor outputs and the cockpit display system. If the CMS engineering process is not carefully applied during the avionics video and computing architecture development, extensive and costly redesign will occur when visual sensor technology upgrades are incorporated. Close monitoring and technical involvement in video standards groups provides the knowledge-base necessary for avionic systems engineering organizations to architect adaptable and extendible cockpit management systems. With the Federal Communications Commission (FCC) in the process of adopting the Digital HDTV Grand Alliance System standard proposed by the Advanced Television Systems Committee (ATSC), the entertainment and telecommunications industries are adopting and supporting the emergence of new serial/parallel digital video interfaces and data compression standards that will drastically alter present NTSC-M video processing architectures. The re-engineering of the U.S. Broadcasting system must initially preserve the electronic equipment wiring networks within broadcast facilities to make the transition to HDTV affordable. International committee activities in technical forums like ITU-R (former CCIR), ANSI/SMPTE, IEEE, and ISO/IEC are establishing global consensus on video signal parameterizations that support a smooth transition from existing analog based broadcasting facilities to fully digital computerized systems. An opportunity exists for implementing these new video interface standards over existing video coax/triax cabling in military aircraft cockpit management systems. Reductions in signal conversion processing steps, major improvement in video noise reduction, and an added capability to pass audio/embedded digital data within the digital video signal stream are the significant performance increases associated with the incorporation of digital video interface standards. By analyzing the historical progression of military CMS developments, establishing a systems engineering process for CMS design, tracing the commercial evolution of video signal standardization, adopting commercial video signal terminology/definitions, and comparing/contrasting CMS architecture modifications using digital video interfaces; this paper provides a technical explanation on how a systems engineering process approach to video interface standardization can result in extendible and affordable cockpit management systems.

System Synchronizes Recordings from Separated Video Cameras

NASA Technical Reports Server (NTRS)

Nail, William; Nail, William L.; Nail, Jasper M.; Le, Doung T.

2009-01-01

A system of electronic hardware and software for synchronizing recordings from multiple, physically separated video cameras is being developed, primarily for use in multiple-look-angle video production. The system, the time code used in the system, and the underlying method of synchronization upon which the design of the system is based are denoted generally by the term "Geo-TimeCode(TradeMark)." The system is embodied mostly in compact, lightweight, portable units (see figure) denoted video time-code units (VTUs) - one VTU for each video camera. The system is scalable in that any number of camera recordings can be synchronized. The estimated retail price per unit would be about $350 (in 2006 dollars). The need for this or another synchronization system external to video cameras arises because most video cameras do not include internal means for maintaining synchronization with other video cameras. Unlike prior video-camera-synchronization systems, this system does not depend on continuous cable or radio links between cameras (however, it does depend on occasional cable links lasting a few seconds). Also, whereas the time codes used in prior video-camera-synchronization systems typically repeat after 24 hours, the time code used in this system does not repeat for slightly more than 136 years; hence, this system is much better suited for long-term deployment of multiple cameras.

This paper will focus on a specific item within the NASA Electronic Information Accessibility Policy - Multimedia Presentation shall have synchronized caption; thus making information accessible to a person with hearing impairment. This synchronized caption will assist a person with hearing or cognitive disability to access the same information as everyone else. This paper focuses on the research and implementation for CC (subtitle option) support to video multimedia. The goal of this research is identify the best available open-source (free) software to achieve synchronized captions requirement and achieve savings, while meeting the security requirement for Government information integrity and assurance. CC and subtitling are processes that display text within a video to provide additional or interpretive information for those whom may need it or those whom chose it. Closed captions typically show the transcription of the audio portion of a program (video) as it occurs (either verbatim or in its edited form), sometimes including non-speech elements (such as sound effects). The transcript can be provided by a third party source or can be extracted word for word from the video. This feature can be made available for videos in two forms: either Soft-Coded or Hard-Coded. Soft-Coded is the more optional version of CC, where you can chose to turn them on if you want, or you can turn them off. Most of the time, when using the Soft-Coded option, the transcript is also provided to the view along-side the video. This option is subject to compromise, whereas the transcript is merely a text file that can be changed by anyone who has access to it. With this option the integrity of the CC is at the mercy of the user. Hard-Coded CC is a more permanent form of CC. A Hard-Coded CC transcript is embedded within a video, without the option of removal.

The flexion test is routinely used in lameness and prepurchase examinations. There is no accepted standard for duration of flexion or evidence that interpretation of results would differ with different durations of flexion. There will be no difference in interpretation of proximal hindlimb flexion for 5 or 60 s. Video recordings of lameness examinations of 34 client-owned horses were performed that included: baseline lameness, proximal hindlimb flexion for 60 s, and flexion of the same limb for 5 s. Videos were edited to blind reviewers to the hypothesis being tested. The baseline lameness video from each horse was paired with each flexion to make 2 pairs of videos for each case. Twenty video pairs were repeated to assess intraobserver repeatability. Fifteen experienced equine clinicians were asked to review the baseline lameness video followed by the flexion test and grade the response to flexion as either positive or negative. Potential associations between the duration of flexion and the likelihood of a positive flexion test were evaluated using generalised linear mixed models. A kappa value was calculated to assess the degree of intraobserver agreement on the repeated videos. Significance level was set at P<0.05. Proximal hindlimb flexion of 60 s was more likely to be called positive than flexion of 5 s (P<0.0001), with the likelihood of the same interpretation 74% of the time. The first flexion performed was more likely to be called positive than subsequent flexions (P = 0.029). Intra-assessor agreement averaged 75% with κ= 0.49. Proximal hindlimb flexion of a limb for 5 s does not yield the same result as flexing a limb for 60 s. Shorter durations of flexion may be useful for clinicians that have good agreement with flexions of 5 and 60 s. © 2011 EVJ Ltd.

Genome-Wide Analysis of A-to-I RNA Editing.

PubMed

Savva, Yiannis A; Laurent, Georges St; Reenan, Robert A

2016-01-01

Adenosine (A)-to-inosine (I) RNA editing is a fundamental posttranscriptional modification that ensures the deamination of A-to-I in double-stranded (ds) RNA molecules. Intriguingly, the A-to-I RNA editing system is particularly active in the nervous system of higher eukaryotes, altering a plethora of noncoding and coding sequences. Abnormal RNA editing is highly associated with many neurological phenotypes and neurodevelopmental disorders. However, the molecular mechanisms underlying RNA editing-mediated pathogenesis still remain enigmatic and have attracted increasing attention from researchers. Over the last decade, methods available to perform genome-wide transcriptome analysis, have evolved rapidly. Within the RNA editing field researchers have adopted next-generation sequencing technologies to identify RNA-editing sites within genomes and to elucidate the underlying process. However, technical challenges associated with editing site discovery have hindered efforts to uncover comprehensive editing site datasets, resulting in the general perception that the collections of annotated editing sites represent only a small minority of the total number of sites in a given organism, tissue, or cell type of interest. Additionally to doubts about sensitivity, existing RNA-editing site lists often contain high percentages of false positives, leading to uncertainty about their validity and usefulness in downstream studies. An accurate investigation of A-to-I editing requires properly validated datasets of editing sites with demonstrated and transparent levels of sensitivity and specificity. Here, we describe a high signal-to-noise method for RNA-editing site detection using single-molecule sequencing (SMS). With this method, authentic RNA-editing sites may be differentiated from artifacts. Machine learning approaches provide a procedure to improve upon and experimentally validate sequencing outcomes through use of computationally predicted, iterative feedback loops. Subsequent use of extensive Sanger sequencing validations can generate accurate editing site lists. This approach has broad application and accurate genome-wide editing analysis of various tissues from clinical specimens or various experimental organisms is now a possibility.

Research on CRISPR-Cas (clustered regularly interspaced short palindromic repeats-CRISPR associated protein) systems has led to the revolutionary CRISPR/Cas9 genome editing technique. However, for most archaea and half of bacteria, exploitation of their native CRISPR-Cas machineries may be more straightforward and convenient. In this study, we harnessed the native type I-B CRISPR-Cas system for precise genome editing in the polyploid haloarchaeon Haloarcula hispanica. After testing different designs, the editing tool was optimized to be a single plasmid that carries both the self-targeting mini-CRISPR and a 600-800 bp donor. Significantly, chromosomal modifications, such as gene deletion, gene tagging or single nucleotide substitution, were precisely introduced into the vast majority of the transformants. Moreover, we showed that simultaneous editing of two genomic loci could also be readily achieved by one step. In summary, our data demonstrate that the haloarchaeal CRISPR-Cas system can be harnessed for genome editing in this polyploid archaeon, and highlight the convenience and efficiency of the native CRISPR-based genome editing strategy.

Although several staging systems have been proposed for pancreatic neuroendocrine tumors (pNETs), the optimal staging system remains unclear. Here, we aimed to assess the application of the newly revised 8th edition American Joint Committee on Cancer (AJCC) staging system for exocrine pancreatic carcinoma (EPC) to pNETs, in comparison with that of other staging systems. We identified pNETs patients from the Surveillance, Epidemiology, and End Results (SEER) database (2004-2014). Overall survival was analyzed using Kaplan-Meier curves with the log-rank test. The predictive accuracy of each staging system was assessed by the concordance index (c-index). Cox proportional hazards regression was conducted to calculate the impact of different stages. In total, 2424 patients with pNETs, including 2350 who underwent resection, were identified using SEER data. Patients with different stages were evenly stratified based on the 8th edition AJCC staging system for EPC. Kaplan-Meier curves were well separated in all patients and patients with resection using the 8th edition AJCC staging system for EPC. Moreover, the hazard ratio increased with worsening disease stage. The c-index of the 8th edition AJCC staging system for EPC was similar to that of the other systems. For pNETs patients, the 8th edition AJCC staging system for EPC exhibits good prognostic discrimination among different stages in both all patients and those with resection. © 2018 The Authors.

Xiu zhen fang (Pocket Formulary) is a recipe book of the Ming Dynasty, inspired and managed by Zhu Su, compiled by Li Heng of liangyisuo (good physician house) in Zhou wangfu (Zhou's royal palace). The book was compiled and published twice during the reigns of the Hongwu and Yongle Emperors of the Ming Dynasty. Because of its high practicability, there were some editions in circulation, and the book was published several times only in the Ming Dynasty. At present, the earliest extanteditionwas the little character version of Yongle, and the version in the 4(th) year of Zhengde Emperor of the Ming Dynasty was a reprinting edition based on the Yongle edition, sharingthe same edition system. Most of the editions appeared after the reign of Zhengtong Emperor of the Ming Dynasty, titled by "kui ben (head version)" and "da quan (complete edition)" were the editionspublished in the local bookshops, which had rather distinct differences from the Yongle edition system not only in the its format but also in its contents.

Web 2.0 sites such as YouTube have become a useful resource for knowledge and are used by medical students as a learning resource. This study aimed at assessing videos covering the nervous system examination on YouTube. A research of YouTube was conducted from 2 November to 2 December 2011 using the following key words "nervous system examination", "nervous system clinical examination", "cranial nerves examination", "CNS examination", "examination of cerebellum", "balance and coordination examination". Only relevant videos in the English language were identified and related URL recorded. For each video, the following information was collected: title, author/s, duration, number of viewers, number of posted comments, and total number of days on YouTube. Using criteria comprising content, technical authority and pedagogy parameters, videos were rated independently by three assessors and grouped into educationally useful and non-educationally useful. A total of 2240 videos were screened; 129 were found to have relevant information to nervous system examination. Analysis revealed that 61 (47%) of the videos provided useful information on the nervous system examination. These videos scored (mean ± SD, 14.9 ± 0.2) and mainly covered examination of the whole nervous system (8 videos, 13%), cranial nerves (42 videos, 69%), upper limbs (6 videos, 10%), lower limbs (3 videos, 5%), balance and co-ordination (2 videos, 3%). The other 68 (53%) videos were not useful educationally; scoring (mean ± SD, 11.1 ± 3.0). The total viewers of all videos was 2,189,434. Useful videos were viewed by 1,050,445 viewers (48% of total viewers). The total viewership per day for useful videos was 1,794.5 and for non-useful videos 1,132.0. The differences between the three assessors were insignificant (less than 0.5 for the mean and 0.3 for the SD). Currently, YouTube provides an adequate resource for learning nervous system examination, which can be used by medical students. However, there were deficiencies in videos covering examination of the cerebellum and balance system. Useful videos can be used as learning resources to medical students.

Cpf1, a CRISPR endonuclease discovered in Prevotella and Francisella 1 bacteria, offers an alternative platform for CRISPR-based genome editing beyond the commonly used CRISPR-Cas9 system originally discovered in Streptococcus pyogenes. This protocol enables the design of engineered CRISPR-Cpf1 components, both CRISPR RNAs (crRNAs) to guide the endonuclease and Cpf1 mRNAs to express the endonuclease protein, and provides experimental procedures for effective genome editing using this system. We also describe quantification of genome-editing activity and off-target effects of the engineered CRISPR-Cpf1 in human cell lines using both T7 endonuclease I (T7E1) assay and targeted deep sequencing. This protocol enables rapid construction and identification of engineered crRNAs and Cpf1 mRNAs to enhance genome-editing efficiency using the CRISPR-Cpf1 system, as well as assessment of target specificity within 2 months. This protocol may also be appropriate for fine-tuning other types of CRISPR systems.

In 2006-2007 and 2007-2008, the authors pilot-tested a filmmaking project, (medical students filmed patients) to assess the project's potential to teach about the challenges of living with serious chronic illness. Two years of second-year medical students (N = 32) from The University of Arizona, working in groups of two or three, were paired with patients and filmed multiple home visits during eight months. Students edited their films to 7 to 10 minutes and added transitions, titles, and music. A mixed audience of students and faculty viewed the resulting 12 films in a "Video Slam." Faculty also used the films in the formal curriculum to illustrate teaching points related to chronic illness. Student filmmakers, on average, made 4.4 visits, collected 5.6 hours of film, and edited for 26.6 hours. Students reported that the project affected what they planned to cover in clinic visits, increased their plans to involve patients in care, enhanced their appreciation for patient-centered care, improved their knowledge of community resources, improved their understanding of allied health professionals' roles, and taught them about patients' innovative adaptations. Overall, students rated the project highly for its impact on their education (mean = 4.52 of 5). Student and faculty viewers of the films (N = 74) found the films compelling (mean = 4.95 of 5) and informative (mean = 4.93 of 5). The authors encountered the ethical dilemmas of deciding who controls the patients' recorded stories and navigating between patient anonymity/confidentiality and allowing patients to use their stories to teach.

Computer-based image analysis of one-dimensional electrophoretic gels used for the separation of DNA restriction fragments.

PubMed Central

Gray, A J; Beecher, D E; Olson, M V

1984-01-01

A stand-alone, interactive computer system has been developed that automates the analysis of ethidium bromide-stained agarose and acrylamide gels on which DNA restriction fragments have been separated by size. High-resolution digital images of the gels are obtained using a camera that contains a one-dimensional, 2048-pixel photodiode array that is mechanically translated through 2048 discrete steps in a direction perpendicular to the gel lanes. An automatic band-detection algorithm is used to establish the positions of the gel bands. A color-video graphics system, on which both the gel image and a variety of operator-controlled overlays are displayed, allows the operator to visualize and interact with critical stages of the analysis. The principal interactive steps involve defining the regions of the image that are to be analyzed and editing the results of the band-detection process. The system produces a machine-readable output file that contains the positions, intensities, and descriptive classifications of all the bands, as well as documentary information about the experiment. This file is normally further processed on a larger computer to obtain fragment-size assignments. Images PMID:6320097

The CRISPR/Cas9 system is capable of editing multiple genes through one-step zygote injection. The preexisting method is largely based on the co-injection of Cas9 DNA (or mRNA) and guide RNAs (gRNAs); however, it is unclear how many genes can be simultaneously edited by this method, and a reliable means to generate transgenic (Tg) animals with multiple gene editing has yet to be developed. Here, we employed non-inheritable maternal Cas9 (maCas9) protein derived from Tg mice with systemic Cas9 overexpression (Cas9 mice). The maCas9 protein in zygotes derived from mating or in vitro fertilization of Tg/+ oocytes and +/+ sperm could successfully edit the target genome. The efficiency of such maCas9-based genome editing was comparable to that of zygote microinjection-based genome editing widely used at present. Furthermore, we demonstrated a novel approach to create "Cas9 transgene-free" gene-modified mice using non-Tg (+/+) zygotes carrying maCas9. The maCas9 protein in mouse zygotes edited nine target loci simultaneously after injection with nine different gRNAs alone. Cas9 mouse-derived zygotes have the potential to facilitate the creation of genetically modified animals carrying the Cas9 transgene, enabling repeatable genome engineering and the production of Cas9 transgene-free mice.

Neurodegenerative disorders are a major public health problem because of the high frequency of these diseases. Genome editing with the CRISPR/Cas9 system is making it possible to modify the sequence of genes linked to these disorders. We designed the KamiCas9 self-inactivating editing system to achieve transient expression of the Cas9 protein and high editing efficiency. In the first application, the gene responsible for Huntington's disease (HD) was targeted in adult mouse neuronal and glial cells. Mutant huntingtin (HTT) was efficiently inactivated in mouse models of HD, leading to an improvement in key markers of the disease. Sequencing of potential off-targets with the constitutive Cas9 system in differentiated human iPSC revealed a very low incidence with only one site above background level. This off-target frequency was significantly reduced with the KamiCas9 system. These results demonstrate the potential of the self-inactivating CRISPR/Cas9 editing for applications in the context of neurodegenerative diseases. Copyright © 2017 The Author(s).

Victor McKusick`s catalog {open_quotes}Mendelian Inheritance in Man{close_quotes} represents the most comprehensive compendum of human genetic disease information available today and has appeared as a series in book form for the last 30 years. The 11th edition will contain almost 7000 entries: approximately 2800 descriptions of human genetic disorders, 700 combined disorder/gene descriptions and 3500 pure gene descriptions. Until recently the content of the catalogs was maintained solely by McKusick with a support staff. However, a distributed editing system has now been established with the following primary components. New entries are initiated in Baltimore by science writers under the guidance ofmore » the senior editors and McKusick, following which the information is made immediately available to the public through online access. The subject editors can then review and edit the new or modified information without impeding the timeliness of entering new information. Entries are being reconstructured so that clinical disorder and gene information is divided into separate entries which will better represent the frequently complex relationship of gene mutations to individual clinical disorders in the data files. Further, each entry is being subdivided into logical topics which will enhance the power of electronic searching, making links between topics and improving readability. The old division of entries into autosomal dominant and recessive, etc., is being abandoned in favor of clinical disorder (phenotypes) and gene catalogs. The information is maintained in an SGML format which facilitates the production of many different types of output varying from the traditional book form to CD ROMs and various online formats including IRx, WAIS, Gopher and World Wide Web. This latter offers the exciting possibility of making hypertext links between entries and other data resources, including photographic, sound and video clips as part of the total MIM information.« less

Making an outreach movie -The Puerto Rico Trench: Exploring the deepest place in the Atlantic Ocean

NASA Astrophysics Data System (ADS)

ten Brink, J.; ten Brink, U. S.

2004-12-01

A new movie will be screened that describes the exploration of the Puerto Rico trench with a multibeam echosounder and its significance to scientific research and tsunami hazard assessment. The movie audience is the general public including high school students. It aims to stimulate interest in Oceanography and to demonstrate scientific processes as they are applied in Geological Oceanography. The extensive use of 3-D visualization fly-bys over the dramatic ocean floor of the Puerto Rico trench should be particularly appealing to a generation growing up on video games and 3-D visualizations. The film is the product of close cooperation between a film maker and a scientist through all stages of its production and post production. This level of close cooperation is necessary because scientists' and film makers' approaches to presentation of information can differ greatly. In making an educational or outreach movie, the scientist must be responsible for the contents of the message, but the film maker has to design an effective delivery method. The creation of this movie was the result of following stages: (1) live action filming during a short research cruise; (2) generating 3-D fly-by using Fledermausr software; (3) rendering the fly-by sequences to a high-definition film; (4) collecting still photos and other supporting material; (5) generating graphs illustrating crucial scientific information and concepts; (6) preparing the script for voiceover narration; (7) working with a professional actor in order to ensure accurate delivery of the information. The biggest challenge in making the movie was the editing stage when the different elements of the movie were put together, incorporating music and voiceover into an aesthetically pleasing, interesting, and above all, scientifically accurate and coherent movie. Post-editing steps included replication of the master copy, package design, and distribution. The movie was completed in several weeks on a modest budget, thanks to modern desktop digital video, editing, voice recording, mixing, and replication technologies. Free copies of the film can be obtained by contacting the second author.

It runs under the Disk Operating System, and includes a user interface, a video I/O interface, an event driven network interface, and a free running or frame synchronous video codec that also acts as the controller for the video and network interfaces. Two video coders have been tested in this system. Simple implementations of Visual Pattern Image Coding and VPISC have both proven to support full motion video conferencing with good visual quality. Future work will concentrate on expanding this prototype to support the motion compensated version of VPISC, as well as encompassing point-to-point modem I/O and multiple network protocols. The application will be ported to multiple hardware platforms and operating systems. The motivation for developing this prototype system is to demonstrate the practicality of software based real time video codecs. Furthermore, software video codecs are not only cheaper, but are more flexible system solutions because they enable different computer platforms to exchange encoded video information without requiring on-board protocol compatible video codex hardware. Software based solutions enable true low cost video conferencing that fits the `open systems' model of interoperability that is so important for building portable hardware and software applications.

Orthogonal-blendshape-based editing system for facial motion capture data.

PubMed

Li, Qing; Deng, Zhigang

2008-01-01

The authors present a novel data-driven 3D facial motion capture data editing system using automated construction of an orthogonal blendshape face model and constrained weight propagation, aiming to bridge the popular facial motion capture technique and blendshape approach. In this work, a 3D facial-motion-capture-editing problem is transformed to a blendshape-animation-editing problem. Given a collected facial motion capture data set, we construct a truncated PCA space spanned by the greatest retained eigenvectors and a corresponding blendshape face model for each anatomical region of the human face. As such, modifying blendshape weights (PCA coefficients) is equivalent to editing their corresponding motion capture sequence. In addition, a constrained weight propagation technique allows animators to balance automation and flexible controls.

Like the first two volumes (5,6), new CDs will contain video and animations of chemical reactions, including clips from our videodiscs ChemDemos (7), ChemDemos II (8), and Titration Techniques (9). Other clips are new, available for the first time in Chemistry Comes Alive! New CCA! CDs will be made available in two varieties for individual users, one to take advantage of the high-quality video that can be displayed by new, faster computers, and another that will play well on older, slower models. In addition, a third variation for network licensing will include video optimized for delivery via the World Wide Web. If all goes according to plan, two new CCA! volumes will be announced in 1999, and CCA! 1 and CCA! 2 will be updated to take advantage of the latest digital video technology. Chem Pages Chem Pages, Laboratory Techniques, was developed by the New Traditions Curriculum Project at the University of Wisconsin-Madison. It is an HTML-based CD-ROM for Mac OS and Windows that contains lessons and tutorials to prepare introductory chemistry students to work in the laboratory. It includes text, photographs, computer graphics, animations, digital video, and voice narration to introduce students to the laboratory equipment and procedures. Regular Issues Programs that have been accepted for publication as Regular Issues in 1999 include a gas chromatography simulation for Windows 95 by Bruce Armitage, a collection of lessons on torsional rotation for organic chemistry students by Ronald Starkey, and a tutorial on pericyclic reactions, also for organic chemistry, by Albert Lee, C. T. So, and C. L. Chan. We have had many recent submissions and submissions of work in progress. In 1999 we will work with the authors and our peer-reviewers to complete and publish these submissions. Submissions include Multimedia Problems for General Chemistry by David Whisnant, lessons on point groups and crystallography by Margaret Kastner, et al., a mass spectrum simulator by Stephen W. Bigger and Robert A. Craig, a tutorial for introductory chemistry on determining the pH of very dilute acid and base solutions by Paul Mihas and George Papageorgiou, and many others. Also under development by the JCE Software staff are The General Chemistry Collection (instructor's edition) CD-ROM along with an updated student edition. An Invitation In collaboration with JCE Online we plan to make available in 1999 support files for JCE Software. These will include not only troubleshooting tips and technical support notes, but also supporting information such as lessons, specific assignments, and activities using JCE Software publications submitted by users. All JCE Software users are invited to contribute to this area. Get in touch with JCE Software and let us know how you are using our materials so that we can share your ideas with others! Although the word software is in our name, many of our publications are not traditional software. We also publish video on videotape, videodisc, and CD-ROM and electronic documents (Mathcad and Mathematica, spreadsheet files and macros, HTML documents, and PowerPoint presentations). Most chemistry instructors who use a computer in their teaching have created or considered creating one or more of these for their classes. If you have an original computer presentation, electronic document, animation, video, or any other item that is not printed text it is probably an appropriate submission for JCE Software. By publishing your work in any branch of the Journal of Chemical Education, you will share your efforts with chemistry instructors and students all over the world and get professional recognition for your achievements.

Development of the Macro Command Editing Executive System for Factory Workers-Oriented Programless Visual Inspection System

NASA Astrophysics Data System (ADS)

Anezaki, Takashi; Wakitani, Kouichi; Nakamura, Masatoshi; Kubo, Hiroyasu

Because visual inspection systems are difficult to tune, they create many problems for the kaizen process. This results in increased development costs and time to assure that the inspection systems function properly. In order to improve inspection system development, we designed an easy-tuning system called a “Program-less” visual inspection system. The ROI macro command which consisted of eight kinds of shape recognition macro commands and decision, operation, control commands was built. Furthermore, the macro command editing executive system was developed by the operation of only the GUI without editing source program. The validity of the ROI macro command was proved by the application of 488 places.

CRISPR-Cas9-Edited Site Sequencing (CRES-Seq): An Efficient and High-Throughput Method for the Selection of CRISPR-Cas9-Edited Clones.

The emergence of clustered regularly interspaced short palindromic repeats-Cas9 (CRISPR-Cas9) gene editing systems has enabled the creation of specific mutants at low cost, in a short time and with high efficiency, in eukaryotic cells. Since a CRISPR-Cas9 system typically creates an array of mutations in targeted sites, a successful gene editing project requires careful selection of edited clones. This process can be very challenging, especially when working with multiallelic genes and/or polyploid cells (such as cancer and plants cells). Here we described a next-generation sequencing method called CRISPR-Cas9 Edited Site Sequencing (CRES-Seq) for the efficient and high-throughput screening of CRISPR-Cas9-edited clones. CRES-Seq facilitates the precise genotyping up to 96 CRISPR-Cas9-edited sites (CRES) in a single MiniSeq (Illumina) run with an approximate sequencing cost of $6/clone. CRES-Seq is particularly useful when multiple genes are simultaneously targeted by CRISPR-Cas9, and also for screening of clones generated from multiallelic genes/polyploid cells. © 2018 by John Wiley & Sons, Inc.

Occurrence of plastid RNA editing in all major lineages of land plants

Freyer, Regina; Kiefer-Meyer, Marie-Christine; Kössel, Hans

1997-01-01

RNA editing changes posttranscriptionally single nucleotides in chloroplast-encoded transcripts. Although much work has been done on mechanistic and functional aspects of plastid editing, little is known about evolutionary aspects of this RNA processing step. To gain a better understanding of the evolution of RNA editing in plastids, we have investigated the editing patterns in ndhB and rbcL transcripts from various species comprising all major groups of land plants. Our results indicate that RNA editing occurs in plastids of bryophytes, fern allies, true ferns, gymnosperms, and angiosperms. Both editing frequencies and editing patterns show a remarkable degree of interspecies variation. Furthermore, we have found that neither plastid editing frequencies nor the editing pattern of a specific transcript correlate with the phylogenetic tree of the plant kingdom. The poor evolutionary conservation of editing sites among closely related species as well as the occurrence of single species-specific editing sites suggest that the differences in the editing patterns and editing frequencies are probably due both to independent loss and to gain of editing sites. In addition, our results indicate that RNA editing is a relatively ancient process that probably predates the evolution of land plants. This supposition is in good agreement with the phylogenetic data obtained for plant mitochondrial RNA editing, thus providing additional evidence for common evolutionary roots of the two plant organellar editing systems.

A solid state video recorder as a direct replacement of a mechanically driven disc recording device in a security system

1989-01-01

Whether upgrading or developing a security system, investing in a solid state video recorder may prove to be quite prudent. Even though the initial cost of a solid state recorder may be more expensive, when comparing it to a disc recorder it is practically maintenance free. Thus, the cost effectiveness of a solid state video recorder over an extended period of time more than justifies the initial expense. This document illustrates the use of a solid state video recorder as a direct replacement. It replaces a mechanically driven disc recorder that existed in a synchronized video recording system. The originalmore » system was called the Universal Video Disc Recorder System. The modified system will now be referred to as the Solid State Video Recording System. 5 figs.« less

CRISPR/Cas9 genome editing strategy has been applied to a variety of species and the tRNA-processing system has been used to compact multiple gRNAs into one synthetic gene for manipulating multiple genes in rice. We optimized and introduced the multiplex gene editing strategy based on the tRNA-processing system into maize. Maize glycine-tRNA was selected to design multiple tRNA-gRNA units for the simultaneous production of numerous gRNAs under the control of one maize U6 promoter. We designed three gRNAs for simplex editing and three multiple tRNA-gRNA units for multiplex editing. The results indicate that this system not only increased the number of targeted sites but also enhanced mutagenesis efficiency in maize. Additionally, we propose an advanced sequence selection of gRNA spacers for relatively more efficient and accurate chromosomal fragment deletion, which is important for complete abolishment of gene function especially long non-coding RNAs (lncRNAs). Our results also indicated that up to four tRNA-gRNA units in one expression cassette design can still work in maize. The examples reported here demonstrate the utility of the tRNA-processing system-based strategy as an efficient multiplex genome editing tool to enhance maize genetic research and breeding.

The psychopathology of James Bond and its implications for the revision of the DSM-(00)7.

To develop a more concise, user-friendly edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM advisory board is probably already hard at work on the DSM-6, so this study is focused on the DSM-(00)7 edition. We conducted an observational study, using a mixed methods approach to analyse the 50th edition boxset of James Bond experiences. James Bond was selected as a suitably complex subject for the basis of a trial of simplifying the DSM. Researchers' televisions and computers from late January to mid-April in Auckland, New Zealand. Following a review of the 23 James Bond video observations, we identified 32 extreme behaviours exhibited by the subject; these could be aggregated into 13 key domains. A Delphi process identified a cluster of eight behaviours that comprise the Bond Adequacy Disorder (BAD). A novel screening scale was then developed, the Bond Additive Descriptors of Anti-Sociality Scale (BADASS), with a binary diagnostic outcome, BAD v Normality Disorder. We propose that these new diagnoses be adopted as the foundation of the DSM-(00)7. The proposed DSM-(00)7 has benefits for both patients and clinicians. Patients will experience reduced stigma, as most individuals will meet the criteria for Normality Disorder. This parsimonious diagnostic approach will also mean clinicians have more time to focus on patient management.

The Impact of Chromatin Dynamics on Cas9-Mediated Genome Editing in Human Cells.

PubMed

Daer, René M; Cutts, Josh P; Brafman, David A; Haynes, Karmella A

2017-03-17

In order to efficiently edit eukaryotic genomes, it is critical to test the impact of chromatin dynamics on CRISPR/Cas9 function and develop strategies to adapt the system to eukaryotic contexts. So far, research has extensively characterized the relationship between the CRISPR endonuclease Cas9 and the composition of the RNA-DNA duplex that mediates the system's precision. Evidence suggests that chromatin modifications and DNA packaging can block eukaryotic genome editing by custom-built DNA endonucleases like Cas9; however, the underlying mechanism of Cas9 inhibition is unclear. Here, we demonstrate that closed, gene-silencing-associated chromatin is a mechanism for the interference of Cas9-mediated DNA editing. Our assays use a transgenic cell line with a drug-inducible switch to control chromatin states (open and closed) at a single genomic locus. We show that closed chromatin inhibits binding and editing at specific target sites and that artificial reversal of the silenced state restores editing efficiency. These results provide new insights to improve Cas9-mediated editing in human and other mammalian cells.

The applicability of new TNM classification for humanpapilloma virus-related oropharyngeal cancer in the 8th edition of the AJCC/UICC TNM staging system in Japan: A single-centre study.

The purpose of this study is to validate the applicability of new TNM classification for human papillomavirus (HPV)-related oropharyngeal cancer (OPC) in the 8th edition of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) TNM staging system in Japan. A total of 91 OPC patients treated with radiation-based therapy between November 2001 and July 2015 were analyzed retrospectively in this study. HPV infection status was evaluated using tumor p16 expression. 40 OPC patients (44.0%) had HPV-positive disease in this study. The distribution of disease stage of HPV-positive OPC patients dramatically changed from the 7th edition to the 8th edition of AJCC/UICC TNM classification. However, neither the 8th edition nor the 7th edition of the AJCC/UICC TNM staging system could adequately predict outcomes of HPV-positive OPC patients in our patient series. On the other hand, our multivariate analysis indicated that matted nodes and age ≥63 were independent prognostic factors for progression-free survival. In addition, HPV-positive OPC patients with stage I without matted nodes showed significantly better overall and progression-free survival compared with those with stage I with matted nodes and stages II and III in the 8th edition of the AJCC/UICC TNM staging system (P=0.008, and P=0.043, respectively). Our results suggested that matted nodes of HPV-positive OPC patients might be additionally examined to apply the 8th edition of AJCC/UICC TNM classification for more adequate predicting outcomes of HPV-positive OPC patients.

Computer and video game addiction-a comparison between game users and non-game users.

Weinstein, Aviv Malkiel

2010-09-01

Computer game addiction is excessive or compulsive use of computer and video games that may interfere with daily life. It is not clear whether video game playing meets diagnostic criteria for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). First objective is to review the literature on computer and video game addiction over the topics of diagnosis, phenomenology, epidemiology, and treatment. Second objective is to describe a brain imaging study measuring dopamine release during computer game playing. Article search of 15 published articles between 2000 and 2009 in Medline and PubMed on computer and video game addiction. Nine abstinent "ecstasy" users and 8 control subjects were scanned at baseline and after performing on a motorbike riding computer game while imaging dopamine release in vivo with [123I] IBZM and single photon emission computed tomography (SPECT). Psycho-physiological mechanisms underlying computer game addiction are mainly stress coping mechanisms, emotional reactions, sensitization, and reward. Computer game playing may lead to long-term changes in the reward circuitry that resemble the effects of substance dependence. The brain imaging study showed that healthy control subjects had reduced dopamine D2 receptor occupancy of 10.5% in the caudate after playing a motorbike riding computer game compared with baseline levels of binding consistent with increased release and binding to its receptors. Ex-chronic "ecstasy" users showed no change in levels of dopamine D2 receptor occupancy after playing this game. This evidence supports the notion that psycho-stimulant users have decreased sensitivity to natural reward. Computer game addicts or gamblers may show reduced dopamine response to stimuli associated with their addiction presumably due to sensitization.

Video at Sea: Telling the Stories of the International Ocean Discovery Program

Seagoing science expeditions offer an ideal opportunity for storytelling. While many disciplines involve fieldwork, few offer the adventure of spending two months at sea on a vessel hundreds of miles from shore with several dozen strangers from all over the world. As a medium, video is nearly ideal for telling these stories; it can capture the thrill of discovery, the agony of disappointment, the everyday details of life at sea, and everything in between. At the International Ocean Discovery Program (IODP, formerly the Integrated Ocean Drilling Program), we have used video as a storytelling medium for several years with great success. Over this timeframe, camera equipment and editing software have become cheaper and easier to use, while web sites such as YouTube and Vimeo have enabled sharing with just a few mouse clicks. When it comes to telling science stories with video, the barriers to entry have never been lower. As such, we have experimented with many different approaches and a wide range of styles. On one end of the spectrum, live "ship-to-shore" broadcasts with school groups - conducted with an iPad and free videoconferencing software such as Skype and Zoom - enable curious minds to engage directly with scientists in real-time. We have also contracted with professional videographers and animators who offer the experience, skill, and equipment needed to produce polished clips of the highest caliber. Amateur videographers (including some scientists looking to make use of their free time on board) have shot and produced impressive shorts using little more than a phone camera. In this talk, I will provide a brief overview of our efforts to connect with the public using video, including a look at how effective certain tactics are for connecting to specific audiences.

For most of the past 100 years, cinema has been the premier medium for defining and expressing relations to the visible world. However, cinematic spectacles delivered in darkened theaters are predicated on a denial of both the body and the physical surroundings of the spectators who are watching it. To overcome these deficiencies, filmmakers have historically turned to narrative, seducing audiences with compelling stories and providing realistic characters with whom to identify. This paper describes several research projects in interactive panoramic cinema that attempt to sidestep the narrative preoccupations of conventional cinema and instead are based on notions of space, movement and embodied spectatorship rather than traditional storytelling. Example projects include interactive works developed with the use of a unique 360 degree camera and editing system, and also development of panoramic imagery for a large projection environment with 14 screens on 3 adjacent walls in a 5-4-5 configuration with observations and findings from an experiment projecting panoramic video on 12 of the 14, in a 4-4-4 270 degree configuration.

Caribbean (English-Speaking) Women in the United States: Cooking for Diabetes Prevention and Management.

PubMed

Thomas, Nigel Mark

2018-01-22

This study surveyed 152 Caribbean-American women about their acculturation levels; their health behaviors; and their perceptions about a website portal for diabetes prevention and management. Participants followed a study link to documents created via SurveyMonkey. The study link included seven edited videos each fewer than 2 min; the videos included ingredients; preparation/cooking instructions; and plating tips for modifying traditional Caribbean meals for diabetes management and prevention. Overall engagement in six healthy living behaviors was moderate Mean = 2.07; Minimum = 1 (Never); Maximum = 3.0 (Always). Self-efficacy for cooking 'healthy' before exploring the website was a mean 3.52 between 40 and 60% confident (SD = 1.509) versus the after Mean of 4.59 closest to 80% confident (SD = 1.154); t = - 10.353, df = 147 (P < 0.001). The results suggest the website did serve as a brief intervention for increasing self-efficacy in cooking meals more consistent with diabetes prevention and management.

A Brazilian educational experiment: teleradiology on web TV.

Since 2004, educational videoconferences have been held in Brazil for paediatric radiologists in training. The RUTE network has been used, a high-speed national research and education network. Twelve videoconferences were recorded by the Health Channel and transformed into TV programmes, both for conventional broadcast and for access via the Internet. Between October 2007 and December 2009 the Health Channel website registered 2378 hits. Our experience suggests that for successful recording of multipoint videoconferences, four areas are important: (1) a pre-planned script is required, for both physicians and film-makers; (2) particular care is necessary when editing the audiovisual material; (3) the audio and video equipment requires careful adjustment to preserve clinical discussions and the quality of radiology images; (4) to produce a product suitable for both TV sets and computer devices, the master tape needs to be encoded in low resolution digital video formats for Internet media (wmv and rm format for streaming, and compressed zip files for downloading) and MPEG format for DVDs.

Automated Visual Event Detection, Tracking, and Data Management System for Cabled- Observatory Video

Edgington, D. R.; Cline, D. E.; Schlining, B.; Raymond, E.

2008-12-01

Ocean observatories and underwater video surveys have the potential to unlock important discoveries with new and existing camera systems. Yet the burden of video management and analysis often requires reducing the amount of video recorded through time-lapse video or similar methods. It's unknown how many digitized video data sets exist in the oceanographic community, but we suspect that many remain under analyzed due to lack of good tools or human resources to analyze the video. To help address this problem, the Automated Visual Event Detection (AVED) software and The Video Annotation and Reference System (VARS) have been under development at MBARI. For detecting interesting events in the video, the AVED software has been developed over the last 5 years. AVED is based on a neuromorphic-selective attention algorithm, modeled on the human vision system. Frames are decomposed into specific feature maps that are combined into a unique saliency map. This saliency map is then scanned to determine the most salient locations. The candidate salient locations are then segmented from the scene using algorithms suitable for the low, non-uniform light and marine snow typical of deep underwater video. For managing the AVED descriptions of the video, the VARS system provides an interface and database for describing, viewing, and cataloging the video. VARS was developed by the MBARI for annotating deep-sea video data and is currently being used to describe over 3000 dives by our remotely operated vehicles (ROV), making it well suited to this deepwater observatory application with only a few modifications. To meet the compute and data intensive job of video processing, a distributed heterogeneous network of computers is managed using the Condor workload management system. This system manages data storage, video transcoding, and AVED processing. Looking to the future, we see high-speed networks and Grid technology as an important element in addressing the problem of processing and accessing large video data sets.

Design of video interface conversion system based on FPGA

NASA Astrophysics Data System (ADS)

Zhao, Heng; Wang, Xiang-jun

2014-11-01

This paper presents a FPGA based video interface conversion system that enables the inter-conversion between digital and analog video. Cyclone IV series EP4CE22F17C chip from Altera Corporation is used as the main video processing chip, and single-chip is used as the information interaction control unit between FPGA and PC. The system is able to encode/decode messages from the PC. Technologies including video decoding/encoding circuits, bus communication protocol, data stream de-interleaving and de-interlacing, color space conversion and the Camera Link timing generator module of FPGA are introduced. The system converts Composite Video Broadcast Signal (CVBS) from the CCD camera into Low Voltage Differential Signaling (LVDS), which will be collected by the video processing unit with Camera Link interface. The processed video signals will then be inputted to system output board and displayed on the monitor.The current experiment shows that it can achieve high-quality video conversion with minimum board size.

Effects of video-game ownership on young boys' academic and behavioral functioning: a randomized, controlled study.

Weis, Robert; Cerankosky, Brittany C

2010-04-01

Young boys who did not own video games were promised a video-game system and child-appropriate games in exchange for participating in an "ongoing study of child development." After baseline assessment of boys' academic achievement and parent- and teacher-reported behavior, boys were randomly assigned to receive the video-game system immediately or to receive the video-game system after follow-up assessment, 4 months later. Boys who received the system immediately spent more time playing video games and less time engaged in after-school academic activities than comparison children. Boys who received the system immediately also had lower reading and writing scores and greater teacher-reported academic problems at follow-up than comparison children. Amount of video-game play mediated the relationship between video-game ownership and academic outcomes. Results provide experimental evidence that video games may displace after-school activities that have educational value and may interfere with the development of reading and writing skills in some children.

Given the need to describe, analyze and index large quantities of marine imagery data for exploration and monitoring activities, a range of specialized image annotation tools have been developed worldwide. Image annotation - the process of transposing objects or events represented in a video or still image to the semantic level, may involve human interactions and computer-assisted solutions. Marine image annotation software (MIAS) have enabled over 500 publications to date. We review the functioning, application trends and developments, by comparing general and advanced features of 23 different tools utilized in underwater image analysis. MIAS requiring human input are basically a graphical user interface, with a video player or image browser that recognizes a specific time code or image code, allowing to log events in a time-stamped (and/or geo-referenced) manner. MIAS differ from similar software by the capability of integrating data associated to video collection, the most simple being the position coordinates of the video recording platform. MIAS have three main characteristics: annotating events in real time, posteriorly to annotation and interact with a database. These range from simple annotation interfaces, to full onboard data management systems, with a variety of toolboxes. Advanced packages allow to input and display data from multiple sensors or multiple annotators via intranet or internet. Posterior human-mediated annotation often include tools for data display and image analysis, e.g. length, area, image segmentation, point count; and in a few cases the possibility of browsing and editing previous dive logs or to analyze the annotations. The interaction with a database allows the automatic integration of annotations from different surveys, repeated annotation and collaborative annotation of shared datasets, browsing and querying of data. Progress in the field of automated annotation is mostly in post processing, for stable platforms or still images. Integration into available MIAS is currently limited to semi-automated processes of pixel recognition through computer-vision modules that compile expert-based knowledge. Important topics aiding the choice of a specific software are outlined, the ideal software is discussed and future trends are presented.

A cross-platform solution for light field based 3D telemedicine.

PubMed

Wang, Gengkun; Xiang, Wei; Pickering, Mark

2016-03-01

Current telehealth services are dominated by conventional 2D video conferencing systems, which are limited in their capabilities in providing a satisfactory communication experience due to the lack of realism. The "immersiveness" provided by 3D technologies has the potential to promote telehealth services to a wider range of applications. However, conventional stereoscopic 3D technologies are deficient in many aspects, including low resolution and the requirement for complicated multi-camera setup and calibration, and special glasses. The advent of light field (LF) photography enables us to record light rays in a single shot and provide glasses-free 3D display with continuous motion parallax in a wide viewing zone, which is ideally suited for 3D telehealth applications. As far as our literature review suggests, there have been no reports of 3D telemedicine systems using LF technology. In this paper, we propose a cross-platform solution for a LF-based 3D telemedicine system. Firstly, a novel system architecture based on LF technology is established, which is able to capture the LF of a patient, and provide an immersive 3D display at the doctor site. For 3D modeling, we further propose an algorithm which is able to convert the captured LF to a 3D model with a high level of detail. For the software implementation on different platforms (i.e., desktop, web-based and mobile phone platforms), a cross-platform solution is proposed. Demo applications have been developed for 2D/3D video conferencing, 3D model display and edit, blood pressure and heart rate monitoring, and patient data viewing functions. The demo software can be extended to multi-discipline telehealth applications, such as tele-dentistry, tele-wound and tele-psychiatry. The proposed 3D telemedicine solution has the potential to revolutionize next-generation telemedicine technologies by providing a high quality immersive tele-consultation experience.

Efficient Generation and Editing of Feeder-free IPSCs from Human Pancreatic Cells Using the CRISPR-Cas9 System.

PubMed

Nandal, Anjali; Mallon, Barbara; Telugu, Bhanu P

2017-11-08

Embryonic and induced pluripotent stem cells can self-renew and differentiate into multiple cell types of the body. The pluripotent cells are thus coveted for research in regenerative medicine and are currently in clinical trials for eye diseases, diabetes, heart diseases, and other disorders. The potential to differentiate into specialized cell types coupled with the recent advances in genome editing technologies including the CRISPR/Cas system have provided additional opportunities for tailoring the genome of iPSC for varied applications including disease modeling, gene therapy, and biasing pathways of differentiation, to name a few. Among the available editing technologies, the CRISPR/Cas9 from Streptococcus pyogenes has emerged as a tool of choice for site-specific editing of the eukaryotic genome. The CRISPRs are easily accessible, inexpensive, and highly efficient in engineering targeted edits. The system requires a Cas9 nuclease and a guide sequence (20-mer) specific to the genomic target abutting a 3-nucleotide "NGG" protospacer-adjacent-motif (PAM) for targeting Cas9 to the desired genomic locus, alongside a universal Cas9 binding tracer RNA (together called single guide RNA or sgRNA). Here we present a step-by-step protocol for efficient generation of feeder-independent and footprint-free iPSC and describe methodologies for genome editing of iPSC using the Cas9 ribonucleoprotein (RNP) complexes. The genome editing protocol is effective and can be easily multiplexed by pre-complexing sgRNAs for more than one target with the Cas9 protein and simultaneously delivering into the cells. Finally, we describe a simplified approach for identification and characterization of iPSCs with desired edits. Taken together, the outlined strategies are expected to streamline generation and editing of iPSC for manifold applications.

Recognition of RNA Editing Sites Is Directed by Unique Proteins in Chloroplasts: Biochemical Identification of cis-Acting Elements and trans-Acting Factors Involved in RNA Editing in Tobacco and Pea Chloroplasts

PubMed Central

Miyamoto, Tetsuya; Obokata, Junichi; Sugiura, Masahiro

2002-01-01

RNA editing in higher-plant chloroplasts involves C-to-U conversions at specific sites. Although in vivo analyses have been performed, little is known about the biochemical aspects of chloroplast editing reactions. Here we improved our original in vitro system and devised a procedure for preparing active chloroplast extracts not only from tobacco plants but also from pea plants. Using our tobacco in vitro system, cis-acting elements were defined for psbE and petB mRNAs. Distinct proteins were found to bind specifically to each cis-element, a 56-kDa protein to the psbE site and a 70-kDa species to the petB site. Pea chloroplasts lack the corresponding editing site in psbE since T is already present in the DNA. Parallel in vitro analyses with tobacco and pea extracts revealed that the pea plant has no editing activity for psbE mRNAs and lacks the 56-kDa protein, whereas petB mRNAs are edited and the 70-kDa protein is also present. Therefore, coevolution of an editing site and its cognate trans-factor was demonstrated biochemically in psbE mRNA editing between tobacco and pea plants. PMID:12215530

2003-04-01

A technical principle about construction of virtual studio has been proposed where orientation tracker and telemeter has been used for improving conventional BETACAM pickup camera and connecting with the software module of the host. A model of virtual camera named Camera & Post-camera Coupling Pair has been put forward, which is different from the common model in computer graphics and has been bound to real BETACAM pickup camera for shooting. The formula has been educed to compute the foreground frame buffer image and the background frame buffer image of the virtual scene whose boundary is based on the depth information of target point of the real BETACAM pickup camera's projective ray. The effect of real-time consistency has been achieved between the video image sequences of the master of ceremonies or players and the CG video image sequences for the virtual scene in spatial position, perspective relationship and image object masking. The experimental result has shown that the technological scheme of construction of virtual studio submitted in this paper is feasible and more applicative and more effective than the existing technology to establish a virtual studio based on color-key and image synthesis with background using non-linear video editing technique.

People watch subtitled audiovisual materials more than ever before. With the proliferation of subtitled content, we are also witnessing an increase in subtitle speeds. However, there is an ongoing controversy about what optimum subtitle speeds should be. This study looks into whether viewers can keep up with increasingly fast subtitles and whether the way people cope with subtitled content depends on their familiarity with subtitling and on their knowledge of the language of the film soundtrack. We tested 74 English, Polish and Spanish viewers watching films subtitled at different speeds (12, 16 and 20 characters per second). The films were either in Hungarian, a language unknown to the participants (Experiment 1), or in English (Experiment 2). We measured viewers' comprehension, self-reported cognitive load, scene and subtitle recognition, preferences and enjoyment. By analyzing people's eye gaze, we were able to discover that most viewers could read the subtitles as well as follow the images, coping well even with fast subtitle speeds. Slow subtitles triggered more re-reading, particularly in English clips, causing more frustration and less enjoyment. Faster subtitles with unreduced text were preferred in the case of English videos, and slower subtitles with text edited down in Hungarian videos. The results provide empirical grounds for revisiting current subtitling practices to enable more efficient processing of subtitled videos for viewers.

Authentication of digital video evidence

2003-11-01

In response to a requirement from the United States Postal Inspection Service, the Technical Support Working Group tasked The Johns Hopkins University Applied Physics Laboratory (JHU/APL) to develop a technique tha will ensure the authenticity, or integrity, of digital video (DV). Verifiable integrity is needed if DV evidence is to withstand a challenge to its admissibility in court on the grounds that it can be easily edited. Specifically, the verification technique must detect additions, deletions, or modifications to DV and satisfy the two-part criteria pertaining to scientific evidence as articulated in Daubert et al. v. Merrell Dow Pharmaceuticals Inc., 43 F3d (9th Circuit, 1995). JHU/APL has developed a prototype digital video authenticator (DVA) that generates digital signatures based on public key cryptography at the frame level of the DV. Signature generation and recording is accomplished at the same time as DV is recorded by the camcorder. Throughput supports the consumer-grade camcorder data rate of 25 Mbps. The DVA software is implemented on a commercial laptop computer, which is connected to a commercial digital camcorder via the IEEE-1394 serial interface. A security token provides agent identification and the interface to the public key infrastructure (PKI) that is needed for management of the public keys central to DV integrity verification.

Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR-associated protein (Cas) system is a newly emerging mutagenesis (gene-editing) tool in genetic engineering. Among the agriculturally important crops, several genes have been successfully mutated by the system, and some agronomic important traits have been rapidly generated, which indicates the potential applications in both scientific research and plant breeding. In this chapter, we describe a standard gene-editing procedure to effectively target rice genes and to make specific rice mutants using the CRISPR/Cas9 system mediated by Agrobacterium transformation.

Enhancing Targeted Genomic DNA Editing in Chicken Cells Using the CRISPR/Cas9 System

2017-01-01

The CRISPR/Cas9 system has enabled highly efficient genome targeted editing for various organisms. However, few studies have focused on CRISPR/Cas9 nuclease-mediated chicken genome editing compared with mammalian genomes. The current study combined CRISPR with yeast Rad52 (yRad52) to enhance targeted genomic DNA editing in chicken DF-1 cells. The efficiency of CRISPR/Cas9 nuclease-induced targeted mutations in the chicken genome was increased to 41.9% via the enrichment of the dual-reporter surrogate system. In addition, the combined effect of CRISPR nuclease and yRad52 dramatically increased the efficiency of the targeted substitution in the myostatin gene using 50-mer oligodeoxynucleotides (ssODN) as the donor DNA, resulting in a 36.7% editing efficiency after puromycin selection. Furthermore, based on the effect of yRad52, the frequency of exogenous gene integration in the chicken genome was more than 3-fold higher than that without yRad52. Collectively, these results suggest that ssODN is an ideal donor DNA for targeted substitution and that CRISPR/Cas9 combined with yRad52 significantly enhances chicken genome editing. These findings could be extensively applied in other organisms. PMID:28068387

Task-oriented situation recognition

2010-04-01

From the advances in computer vision methods for the detection, tracking and recognition of objects in video streams, new opportunities for video surveillance arise: In the future, automated video surveillance systems will be able to detect critical situations early enough to enable an operator to take preventive actions, instead of using video material merely for forensic investigations. However, problems such as limited computational resources, privacy regulations and a constant change in potential threads have to be addressed by a practical automated video surveillance system. In this paper, we show how these problems can be addressed using a task-oriented approach. The system architecture of the task-oriented video surveillance system NEST and an algorithm for the detection of abnormal behavior as part of the system are presented and illustrated for the surveillance of guests inside a video-monitored building.

4DCAPTURE: a general purpose software package for capturing and analyzing two- and three-dimensional motion data acquired from video sequences

NASA Astrophysics Data System (ADS)

Walton, James S.; Hodgson, Peter; Hallamasek, Karen; Palmer, Jake

2003-07-01

4DVideo is creating a general purpose capability for capturing and analyzing kinematic data from video sequences in near real-time. The core element of this capability is a software package designed for the PC platform. The software ("4DCapture") is designed to capture and manipulate customized AVI files that can contain a variety of synchronized data streams -- including audio, video, centroid locations -- and signals acquired from more traditional sources (such as accelerometers and strain gauges.) The code includes simultaneous capture or playback of multiple video streams, and linear editing of the images (together with the ancilliary data embedded in the files). Corresponding landmarks seen from two or more views are matched automatically, and photogrammetric algorithms permit multiple landmarks to be tracked in two- and three-dimensions -- with or without lens calibrations. Trajectory data can be processed within the main application or they can be exported to a spreadsheet where they can be processed or passed along to a more sophisticated, stand-alone, data analysis application. Previous attempts to develop such applications for high-speed imaging have been limited in their scope, or by the complexity of the application itself. 4DVideo has devised a friendly ("FlowStack") user interface that assists the end-user to capture and treat image sequences in a natural progression. 4DCapture employs the AVI 2.0 standard and DirectX technology which effectively eliminates the file size limitations found in older applications. In early tests, 4DVideo has streamed three RS-170 video sources to disk for more than an hour without loss of data. At this time, the software can acquire video sequences in three ways: (1) directly, from up to three hard-wired cameras supplying RS-170 (monochrome) signals; (2) directly, from a single camera or video recorder supplying an NTSC (color) signal; and (3) by importing existing video streams in the AVI 1.0 or AVI 2.0 formats. The latter is particularly useful for high-speed applications where the raw images are often captured and stored by the camera before being downloaded. Provision has been made to synchronize data acquired from any combination of these video sources using audio and visual "tags." Additional "front-ends," designed for digital cameras, are anticipated.

Multilocation Video Conference By Optical Fiber

NASA Astrophysics Data System (ADS)

Gray, Donald J.

1982-10-01

An experimental system that permits interconnection of many offices in a single video conference is described. Video images transmitted to conference participants are selected by the conference chairman and switched by a microprocessor-controlled video switch. Speakers can, at their choice, transmit their own images or images of graphics they wish to display. Users are connected to the Switching Center by optical fiber subscriber loops that carry analog video, digitized telephone, data and signaling. The same system also provides user-selectable distribution of video program and video library material. Experience in the operation of the conference system is discussed.

Little is known about the physiological demands placed on officials during sporting activities. The purpose of this study was to ascertain the movement activities of referees during English Premiership rugby football union matches, and to determine the frequency and duration of these activities. Nine referees who were ranked in the top 20 referees in England were videotaped during a total of 19 matches. During playback of the videotapes, a single observer coded the referees' activities into one of six distinct categories (standing, walking forwards, walking backwards, jogging, running and sprinting) using a computerized video editing system (Observer Video-Pro). The referees were timed over a 20 m distance for the modes of locomotory activity, and the average velocity of the referee for each activity was used to calculate the total distance covered in each mode of activity during matches. The total distance covered during a match was (chi +/- SD) 8581 +/- 668 m. The mean percentage of total playing time spent in each activity was: standing still, 37.0 +/- 11.0%; walking forward, 29.5 +/- 7.2%; walking backward, 9.9 +/- 3.2%; jogging, 12.8 +/- 3.2%; running, 9.8 +/- 2.3%; and sprinting, 1.0 +/- 0.4%. There were a total of 672 transitions between modes of activity during a match. The results of this study suggest that refereeing top English rugby football union matches is physically demanding. Although the major physiological load is placed on the oxygen transport system, frequent sprint bouts and the associated requirements for acceleration and deceleration impose additional metabolic demands on referees. This information may be used in the design of physical training programmes to optimize performance in referees.

To develop a genome editing method using the CRISPR/Cas9 system in Aspergillus oryzae, the industrial filamentous fungus used in Japanese traditional fermentation and for the production of enzymes and heterologous proteins. To develop the CRISPR/Cas9 system as a genome editing technique for A. oryzae, we constructed plasmids expressing the gene encoding Cas9 nuclease and single guide RNAs for the mutagenesis of target genes. We introduced these into an A. oryzae strain and obtained transformants containing mutations within each target gene that exhibited expected phenotypes. The mutational rates ranged from 10 to 20 %, and 1 bp deletions or insertions were the most commonly induced mutations. We developed a functional and versatile genome editing method using the CRISPR/Cas9 system in A. oryzae. This technique will contribute to the use of efficient targeted mutagenesis in many A. oryzae industrial strains.

Not going it alone: scientists and their work featured online at FrontierScientists

NASA Astrophysics Data System (ADS)

O'Connell, E. A.; Nielsen, L.

2015-12-01

Science outreach demystifies science, and outreach media gives scientists a voice to engage the public. Today scientists are expected to communicate effectively not only with peers but also with a braod public audience, yet training incentiives are sometimes scarce. Media creation training is even less emphasized. Editing video to modern standards takes practice; arrangling light and framing shots isn't intuitive. While great tutorials exist, learning videography, story boarding, editing and sharing techniques will always require a commitment of time and effort. Yet ideally sharing science should be low-hanging fruit. FrontierScientists, a science-sharing website funded by the NSF, seeks to let scientists display their breakthroughs and share their excitement for their work with the public by working closely yet non-exhaustively with a professional media team. A director and videographer join scientists to film first-person accounts in the field or lab. Pictures and footage with field site explanations give media creators raw material. Scientists communicate efficiently and retain editorial control over the project, but a small team of media creators craft the public aimed content. A series of engaging short videos with narrow focuses illuminate the science. Written articles support with explanations. Social media campaigns spread the word, link content, welcome comments and keep abreast of changing web requirements. All FrontierScientists featured projects are aggregated to one mobile-friendly site available online or via an App. There groupings of Arctic-focused science provide a wealth of topics and content to explore. Scientists describe why their science is important, what drew them to it, and why the average American should care. When scientists share their work it's wonderful; a team approach is a schedule-friendly way that lets them serve as science communicators without taking up a handful of extra careers.

Prognostic value of the 8th edition of the tumor-node-metastasis classification for patients with papillary thyroid carcinoma: a single-institution study at a high-volume center in Japan.

The tumor-node-metastasis (TNM) staging system is most commonly adopted to evaluate the prognosis of patients with thyroid carcinoma. The 8 th edition of the TNM staging system, an extensively revised version of the 7 th edition, was recently released. We aimed to investigate whether and how well the 8 th edition reflects the cause-specific survival (CSS) of patients with papillary thyroid carcinoma by analyzing the cases in 5,892 patients who underwent initial surgery at Kuma Hospital between 1987 and 2005. The median postoperative follow-up duration was 178 months (range: 6-357 months). One patient with T4b disease was excluded from the analysis. Overall, 116 (2.0%) patients died of thyroid carcinoma. The proportion of variance explained (PVE) for CSS in the 7 th and 8 th editions was 10.69 and 10.97, respectively. Using the 7 th edition, CSS of patients with stage IVA and stage III disease was similar (p = 0.32). In contrast, using the 8 th edition, CSS was poorer in stage II than in stage I (p < 0.001), in stage III than in stage II (p < 0.001), and in stage IVB than in stage III (p < 0.001). Similar results were observed for disease-free survival. Although we could not establish any objective evidence that the 8 th edition is superior to the 7 th edition, the 8 th edition is simpler and more convenient, as it includes fewer stages and addresses the issue of the 7 th edition where stage IVA and III patients had similar prognoses.

Application of robust face recognition in video surveillance systems

NASA Astrophysics Data System (ADS)

Zhang, De-xin; An, Peng; Zhang, Hao-xiang

2018-03-01

In this paper, we propose a video searching system that utilizes face recognition as searching indexing feature. As the applications of video cameras have great increase in recent years, face recognition makes a perfect fit for searching targeted individuals within the vast amount of video data. However, the performance of such searching depends on the quality of face images recorded in the video signals. Since the surveillance video cameras record videos without fixed postures for the object, face occlusion is very common in everyday video. The proposed system builds a model for occluded faces using fuzzy principal component analysis (FPCA), and reconstructs the human faces with the available information. Experimental results show that the system has very high efficiency in processing the real life videos, and it is very robust to various kinds of face occlusions. Hence it can relieve people reviewers from the front of the monitors and greatly enhances the efficiency as well. The proposed system has been installed and applied in various environments and has already demonstrated its power by helping solving real cases.

Targeted activation of diverse CRISPR-Cas systems for mammalian genome editing via proximal CRISPR targeting.

PubMed

Chen, Fuqiang; Ding, Xiao; Feng, Yongmei; Seebeck, Timothy; Jiang, Yanfang; Davis, Gregory D

2017-04-07

Bacterial CRISPR-Cas systems comprise diverse effector endonucleases with different targeting ranges, specificities and enzymatic properties, but many of them are inactive in mammalian cells and are thus precluded from genome-editing applications. Here we show that the type II-B FnCas9 from Francisella novicida possesses novel properties, but its nuclease function is frequently inhibited at many genomic loci in living human cells. Moreover, we develop a proximal CRISPR (termed proxy-CRISPR) targeting method that restores FnCas9 nuclease activity in a target-specific manner. We further demonstrate that this proxy-CRISPR strategy is applicable to diverse CRISPR-Cas systems, including type II-C Cas9 and type V Cpf1 systems, and can facilitate precise gene editing even between identical genomic sites within the same genome. Our findings provide a novel strategy to enable use of diverse otherwise inactive CRISPR-Cas systems for genome-editing applications and a potential path to modulate the impact of chromatin microenvironments on genome modification.

Identifying the Machine Translation Error Types with the Greatest Impact on Post-editing Effort

Daems, Joke; Vandepitte, Sonia; Hartsuiker, Robert J.; Macken, Lieve

2017-01-01

Translation Environment Tools make translators’ work easier by providing them with term lists, translation memories and machine translation output. Ideally, such tools automatically predict whether it is more effortful to post-edit than to translate from scratch, and determine whether or not to provide translators with machine translation output. Current machine translation quality estimation systems heavily rely on automatic metrics, even though they do not accurately capture actual post-editing effort. In addition, these systems do not take translator experience into account, even though novices’ translation processes are different from those of professional translators. In this paper, we report on the impact of machine translation errors on various types of post-editing effort indicators, for professional translators as well as student translators. We compare the impact of MT quality on a product effort indicator (HTER) with that on various process effort indicators. The translation and post-editing process of student translators and professional translators was logged with a combination of keystroke logging and eye-tracking, and the MT output was analyzed with a fine-grained translation quality assessment approach. We find that most post-editing effort indicators (product as well as process) are influenced by machine translation quality, but that different error types affect different post-editing effort indicators, confirming that a more fine-grained MT quality analysis is needed to correctly estimate actual post-editing effort. Coherence, meaning shifts, and structural issues are shown to be good indicators of post-editing effort. The additional impact of experience on these interactions between MT quality and post-editing effort is smaller than expected. PMID:28824482

Statistical Physics Approaches to RNA Editing

NASA Astrophysics Data System (ADS)

Bundschuh, Ralf

2012-02-01

The central dogma of molecular Biology states that DNA is transcribed base by base into RNA which is in turn translated into proteins. However, some organisms edit their RNA before translation by inserting, deleting, or substituting individual or short stretches of bases. In many instances the mechanisms by which an organism recognizes the positions at which to edit or by which it performs the actual editing are unknown. One model system that stands out by its very high rate of on average one out of 25 bases being edited are the Myxomycetes, a class of slime molds. In this talk we will show how the computational methods and concepts from statistical Physics can be used to analyze DNA and protein sequence data to predict editing sites in these slime molds and to guide experiments that identified previously unknown types of editing as well as the complete set of editing events in the slime mold Physarum polycephalum.

Converting laserdisc video to digital video: a demonstration project using brain animations.

PubMed

Jao, C S; Hier, D B; Brint, S U

1995-01-01

Interactive laserdiscs are of limited value in large group learning situations due to the expense of establishing multiple workstations. The authors implemented an alternative to laserdisc video by using indexed digital video combined with an expert system. High-quality video was captured from a laserdisc player and combined with waveform audio into an audio-video-interleave (AVI) file format in the Microsoft Video-for-Windows environment (Microsoft Corp., Seattle, WA). With the use of an expert system, a knowledge-based computer program provided random access to these indexed AVI files. The program can be played on any multimedia computer without the need for laserdiscs. This system offers a high level of interactive video without the overhead and cost of a laserdisc player.

Simulation-based training has become an accepted clinical training andragogy in high-resource settings with its use increasing in low-resource settings. Video recordings of simulated scenarios are commonly used by facilitators. Beyond using the videos during debrief sessions, researchers can also analyze the simulation videos to quantify technical and nontechnical skills during simulated scenarios over time. Little is known about the feasibility and use of large-scale systems to video record and analyze simulation and debriefing data for monitoring and evaluation in low-resource settings. This manuscript describes the process of designing and implementing a large-scale video monitoring system. Mentees and Mentors were consented and all simulations and debriefs conducted at 320 Primary Health Centers (PHCs) were video recorded. The system design, number of video recordings, and inter-rater reliability of the coded videos were assessed. The final dataset included a total of 11,278 videos. Overall, a total of 2,124 simulation videos were coded and 183 (12%) were blindly double-coded. For the double-coded sample, the average inter-rater reliability (IRR) scores were 80% for nontechnical skills, and 94% for clinical technical skills. Among 4,450 long debrief videos received, 216 were selected for coding and all were double-coded. Data quality of simulation videos was found to be very good in terms of recorded instances of "unable to see" and "unable to hear" in Phases 1 and 2. This study demonstrates that video monitoring systems can be effectively implemented at scale in resource limited settings. Further, video monitoring systems can play several vital roles within program implementation, including monitoring and evaluation, provision of actionable feedback to program implementers, and assurance of program fidelity.

Spasmodic dysphonia (SD) can be difficult to diagnose, and patients often see multiple physicians for many years before diagnosis. Improving the speed of diagnosis for individuals with SD may decrease the time to treatment and improve patient quality of life more quickly. To assess whether the diagnosis of SD can be accurately predicted through auditory cues alone without the assistance of visual cues offered by laryngoscopic examination. Single-masked, case-control study at a specialized referral center that included patients who underwent laryngoscopic examination as part of a multidisciplinary workup for dysphonia. Twenty-two patients were selected in total: 10 with SD, 5 with vocal tremor, and 7 controls without SD or vocal tremor. The laryngoscopic examination was recorded, deidentified, and edited to make 3 media clips for each patient: video alone, audio alone, and combined video and audio. These clips were randomized and presented to 3 fellowship-trained laryngologist raters (A.D.R., A.T.H., and A.M.K.), who established the most probable diagnosis for each clip. Intrarater and interrater reliability were evaluated using repeat clips incorporated in the presentations. We measured diagnostic accuracy for video-only, audio-only, and combined multimedia clips. These measures were established before data collection. Data analysis was accomplished with analysis of variance and Tukey honestly significant differences. Of patients with SD, diagnostic accuracy was 10%, 73%, and 73% for video-only, audio-only, and combined, respectively (P < .001, df = 2). Of patients with vocal tremor, diagnostic accuracy was 93%, 73%, and 100% for video-only, audio-only, and combined, respectively (P = .05, df = 2). Of the controls, diagnostic accuracy was 81%, 19%, and 62% for video-only, audio-only, and combined, respectively (P < .001, df = 2). The diagnosis of SD during examination is based primarily on auditory cues. Viewing combined audio and video clips afforded no change in diagnostic accuracy compared with audio alone. Laryngoscopy serves an important role in the diagnosis of SD by excluding other pathologic causes and identifying vocal tremor.

Harnessing CRISPR-Cas systems for bacterial genome editing.

PubMed

Selle, Kurt; Barrangou, Rodolphe

2015-04-01

Manipulation of genomic sequences facilitates the identification and characterization of key genetic determinants in the investigation of biological processes. Genome editing via clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated (Cas) constitutes a next-generation method for programmable and high-throughput functional genomics. CRISPR-Cas systems are readily reprogrammed to induce sequence-specific DNA breaks at target loci, resulting in fixed mutations via host-dependent DNA repair mechanisms. Although bacterial genome editing is a relatively unexplored and underrepresented application of CRISPR-Cas systems, recent studies provide valuable insights for the widespread future implementation of this technology. This review summarizes recent progress in bacterial genome editing and identifies fundamental genetic and phenotypic outcomes of CRISPR targeting in bacteria, in the context of tool development, genome homeostasis, and DNA repair.

2017-01-01

Genome editing tools have the potential to change the genomic architecture of a genome at precise locations, with desired accuracy. These tools have been efficiently used for trait discovery and for the generation of plants with high crop yields and resistance to biotic and abiotic stresses. Due to complex genomic architecture, it is challenging to edit all of the genes/genomes using a particular genome editing tool. Therefore, to overcome this challenging task, several genome editing tools have been developed to facilitate efficient genome editing. Some of the major genome editing tools used to edit plant genomes are: Homologous recombination (HR), zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), pentatricopeptide repeat proteins (PPRs), the CRISPR/Cas9 system, RNA interference (RNAi), cisgenesis, and intragenesis. In addition, site-directed sequence editing and oligonucleotide-directed mutagenesis have the potential to edit the genome at the single-nucleotide level. Recently, adenine base editors (ABEs) have been developed to mutate A-T base pairs to G-C base pairs. ABEs use deoxyadeninedeaminase (TadA) with catalytically impaired Cas9 nickase to mutate A-T base pairs to G-C base pairs. PMID:29257124

2016-01-01

Objective Biomedical videos as open educational resources (OERs) are increasingly proliferating on the Internet. Unfortunately, seeking personally valuable content from among the vast corpus of quality yet diverse OER videos is nontrivial due to limitations of today’s keyword- and content-based video retrieval techniques. To address this need, this study introduces a novel visual navigation system that facilitates users’ information seeking from biomedical OER videos in mass quantity by interactively offering visual and textual navigational clues that are both semantically revealing and user-friendly. Materials and Methods The authors collected and processed around 25 000 YouTube videos, which collectively last for a total length of about 4000 h, in the broad field of biomedical sciences for our experiment. For each video, its semantic clues are first extracted automatically through computationally analyzing audio and visual signals, as well as text either accompanying or embedded in the video. These extracted clues are subsequently stored in a metadata database and indexed by a high-performance text search engine. During the online retrieval stage, the system renders video search results as dynamic web pages using a JavaScript library that allows users to interactively and intuitively explore video content both efficiently and effectively. Results The authors produced a prototype implementation of the proposed system, which is publicly accessible at https://patentq.njit.edu/oer. To examine the overall advantage of the proposed system for exploring biomedical OER videos, the authors further conducted a user study of a modest scale. The study results encouragingly demonstrate the functional effectiveness and user-friendliness of the new system for facilitating information seeking from and content exploration among massive biomedical OER videos. Conclusion Using the proposed tool, users can efficiently and effectively find videos of interest, precisely locate video segments delivering personally valuable information, as well as intuitively and conveniently preview essential content of a single or a collection of videos.

Lin, Chia-Wen; Chang, Yao-Jen; Wang, Chih-Ming; Chen, Yung-Chang; Sun, Ming-Ting

2002-12-01

This paper presents an H.323 standard compliant virtual video conferencing system. The proposed system not only serves as a multipoint control unit (MCU) for multipoint connection but also provides a gateway function between the H.323 LAN (local-area network) and the H.324 WAN (wide-area network) users. The proposed virtual video conferencing system provides user-friendly object compositing and manipulation features including 2D video object scaling, repositioning, rotation, and dynamic bit-allocation in a 3D virtual environment. A reliable, and accurate scheme based on background image mosaics is proposed for real-time extracting and tracking foreground video objects from the video captured with an active camera. Chroma-key insertion is used to facilitate video objects extraction and manipulation. We have implemented a prototype of the virtual conference system with an integrated graphical user interface to demonstrate the feasibility of the proposed methods.

2009-02-01

Many emergency response units are currently faced with restrictive budgets that prohibit their use of advanced technology-based training solutions. Our work focuses on creating an affordable, mobile, state-of-the-art emergency response training solution through the integration of low-cost, commercially available products. The system we have developed consists of tracking, audio, and video capability, coupled with other sensors that can all be viewed through a unified visualization system. In this paper we focus on the video sub-system which helps provide real time tracking and video feeds from the training environment through a system of wearable and stationary cameras. These two camera systems interface with a management system that handles storage and indexing of the video during and after training exercises. The wearable systems enable the command center to have live video and tracking information for each trainee in the exercise. The stationary camera systems provide a fixed point of reference for viewing action during the exercise and consist of a small Linux based portable computer and mountable camera. The video management system consists of a server and database which work in tandem with a visualization application to provide real-time and after action review capability to the training system.

Contemporary improvements in the type II clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) system offer a convenient way for genome editing in zebrafish. However, the low efficiencies of genome editing and germline transmission require a time-intensive and laborious screening work. Here, we reported a method based on in vitro oocyte storage by injecting oocytes in advance and incubating them in oocyte storage medium to significantly improve the efficiencies of genome editing and germline transmission by in vitro fertilization (IVF) in zebrafish. Compared to conventional methods, the prior micro-injection of zebrafish oocytes improved the efficiency of genome editing, especially for the sgRNAs with low targeting efficiency. Due to high throughputs, simplicity and flexible design, this novel strategy will provide an efficient alternative to increase the speed of generating heritable mutants in zebrafish by using CRISPR/Cas9 system.

2010-01-01

This slide presentation reviews the use of digital video with space systems and networks. The earliest use of video was the use of film precluding live viewing, which gave way to live television from space. This has given way to digital video using internet protocol for transmission. This has provided for many improvements with new challenges. Some of these ehallenges are reviewed. The change to digital video transmitted over space systems can provide incredible imagery, however the process must be viewed as an entire system, rather than piece-meal.

Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein (Cas) is a microbial adaptive immune system. CRISPR-Cas systems are classified into two main classes and six types. Cpf1 is a putative type V (class II) CRISPR effector, which has revolutionized the genome editing approaches through multiple distinct features such as using T-rich protospacer-adjacent motif, applying a short guide RNA lacking trans-activating crRNA, introducing a staggered double-strand break, and possessing RNA processing activity in addition to DNA nuclease activity. In the present review, we attempt to highlight most recent advances in CRISPR-Cpf1 (CRISPR-Cas12a) system in particular, considering ground expeditions of the nature and the biology of this system, introducing novel Cpf1 variants that have broadened the versatility and feasibility of CRISPR-Cpf1 system, and lastly the great impact of the CRISPR-Cpf1 system on the manipulation of the genome of prokaryotic, mammalian, and plant models is summarized. With regard to recent developments in utilizing the CRISPR-Cpf1 system in genome editing of various organisms, it can be concluded with confidence that this system is a reliable molecular toolbox of genome editing approaches.

Corynebacterium glutamicum is an important industrial metabolite producer that is difficult to genetically engineer. Although the Streptococcus pyogenes (Sp) CRISPR-Cas9 system has been adapted for genome editing of multiple bacteria, it cannot be introduced into C. glutamicum. Here we report a Francisella novicida (Fn) CRISPR-Cpf1-based genome-editing method for C. glutamicum. CRISPR-Cpf1, combined with single-stranded DNA (ssDNA) recombineering, precisely introduces small changes into the bacterial genome at efficiencies of 86–100%. Large gene deletions and insertions are also obtained using an all-in-one plasmid consisting of FnCpf1, CRISPR RNA, and homologous arms. The two CRISPR-Cpf1-assisted systems enable N iterative rounds of genome editing in 3N+4 or 3N+2 days. A proof-of-concept, codon saturation mutagenesis at G149 of γ-glutamyl kinase relieves L-proline inhibition using Cpf1-assisted ssDNA recombineering. Thus, CRISPR-Cpf1-based genome editing provides a highly efficient tool for genetic engineering of Corynebacterium and other bacteria that cannot utilize the Sp CRISPR-Cas9 system. PMID:28469274

The changing landscape of gene editing in hematopoietic stem cells: a step towards Cas9 clinical translation.

PubMed

Dever, Daniel P; Porteus, Matthew H

2017-11-01

Since the discovery two decades ago that programmable endonucleases can be engineered to modify human cells at single nucleotide resolution, the concept of genome editing was born. Now these technologies are being applied to therapeutically relevant cell types, including hematopoietic stem cells (HSC), which possess the power to repopulate an entire blood and immune system. The purpose of this review is to discuss the changing landscape of genome editing in hematopoietic stem cells (GE-HSC) from the discovery stage to the preclinical stage, with the imminent goal of clinical translation for the treatment of serious genetic diseases of the blood and immune system. With the discovery that the RNA-programmable (sgRNA) clustered regularly interspace short palindromic repeats (CRISPR)-Cas9 nuclease (Cas9/sgRNA) systems can be easily used to precisely modify the human genome in 2012, a genome-editing revolution of hematopoietic stem cells (HSC) has bloomed. We have observed that over the last 2 years, academic institutions and small biotech companies are developing HSC-based Cas9/sgRNA genome-editing curative strategies to treat monogenic disorders, including β-hemoglobinopathies and primary immunodeficiencies. We will focus on recent publications (within the past 2 years) that employ different genome-editing strategies to 'hijack' the cell's endogenous double-strand repair pathways to confer a disease-specific therapeutic advantage. The number of genome-editing strategies in HSCs that could offer therapeutic potential for diseases of the blood and immune system have dramatically risen over the past 2 years. The HSC-based genome-editing field is primed to enter clinical trials in the subsequent years. We will summarize the major advancements for the development of novel autologous GE-HSC cell and gene therapy strategies for hematopoietic diseases that are candidates for curative allogeneic bone marrow transplantation.

Ralstonia eutropha is an important bacterium for the study of polyhydroxyalkanoates (PHAs) synthesis and CO 2 fixation, which makes it a potential strain for industrial PHA production and attractive host for CO 2 conversion. Although the bacterium is not recalcitrant to genetic manipulation, current methods for genome editing based on group II introns or single crossover integration of a suicide plasmid are inefficient and time-consuming, which limits the genetic engineering of this organism. Thus, developing an efficient and convenient method for R. eutropha genome editing is imperative. An efficient genome editing method for R. eutropha was developed using an electroporation-based CRISPR-Cas9 technique. In our study, the electroporation efficiency of R. eutropha was found to be limited by its restriction-modification (RM) systems. By searching the putative RM systems in R. eutropha H16 using REBASE database and comparing with that in E. coli MG1655, five putative restriction endonuclease genes which are related to the RM systems in R. eutropha were predicated and disrupted. It was found that deletion of H16_A0006 and H16_A0008 - 9 increased the electroporation efficiency 1658 and 4 times, respectively. Fructose was found to reduce the leaky expression of the arabinose-inducible pBAD promoter, which was used to optimize the expression of cas9 , enabling genome editing via homologous recombination based on CRISPR-Cas9 in R. eutropha . A total of five genes were edited with efficiencies ranging from 78.3 to 100%. The CRISPR-Cpf1 system and the non-homologous end joining mechanism were also investigated, but failed to yield edited strains. We present the first genome editing method for R. eutropha using an electroporation-based CRISPR-Cas9 approach, which significantly increased the efficiency and decreased time to manipulate this facultative chemolithoautotrophic microbe. The novel technique will facilitate more advanced researches and applications of R. eutropha for PHA production and CO 2 conversion.

Video analysis of the biomechanics of a bicycle accident resulting in significant facial fractures.

Syed, Shameer H; Willing, Ryan; Jenkyn, Thomas R; Yazdani, Arjang

2013-11-01

This study aimed to use video analysis techniques to determine the velocity, impact force, angle of impact, and impulse to fracture involved in a video-recorded bicycle accident resulting in facial fractures. Computed tomographic images of the resulting facial injury are presented for correlation with data and calculations. To our knowledge, such an analysis of an actual recorded trauma has not been reported in the literature. A video recording of the accident was split into frames and analyzed using an image editing program. Measurements of velocity and angle of impact were obtained from this analysis, and the force of impact and impulse were calculated using the inverse dynamic method with connected rigid body segments. These results were then correlated with the actual fracture pattern found on computed tomographic imaging of the subject's face. There was an impact velocity of 6.25 m/s, impact angles of 14 and 6.3 degrees of neck extension and axial rotation, respectively, an impact force of 1910.4 N, and an impulse to fracture of 47.8 Ns. These physical parameters resulted in clinically significant bilateral mid-facial Le Fort II and III pattern fractures. These data confer further understanding of the biomechanics of bicycle-related accidents by correlating an actual clinical outcome with the kinematic and dynamic parameters involved in the accident itself and yielding a concrete evidence of the velocity, force, and impulse necessary to cause clinically significant facial trauma. These findings can aid in the design of protective equipment for bicycle riders to help avoid this type of injury.

Knowledge Engineering for Preservation and Future use of Institutional Knowledge

Moreman, Douglas; Dyer, John

1996-01-01

This Project has two main thrusts-preservation of special knowledge and its useful representation via computers. NASA is losing the expertise of its engineers and scientists who put together the great missions of the past. We no longer are landing men on the moon. Some of the equipment still used today (such as the RL-10 rocket) was designed decades ago by people who are now retiring. Furthermore, there has been a lack, in some areas of technology, of new projects that overlap with the old and that would have provided opportunities for monitoring by senior engineers of the young ones. We are studying this problem and trying out a couple of methods of soliciting and recording rare knowledge from experts. One method is that of Concept Maps which produces a graphical interface to knowledge even as it helps solicit that knowledge. We arranged for experienced help in this method from John Coffey of the Institute of Human and Machine Technology at the University of West Florida. A second method which we plan to try out in May, is a video-taped review of selected failed missions (e.g., the craft tumbled and blew up). Five senior engineers (most already retired from NASA) will, as a team, analyze available data, illustrating their thought processes as they try to solve the problem of why a space craft failed to complete its mission. The session will be captured in high quality audio and with at least two video cameras. The video can later be used to plan future concept mapping interviews and, in edited form, be a product in itself. Our computer representations of the amassed knowledge may eventually, via the methods of expert systems, be joined with other software being prepared as a suite of tools to aid future engineers designing rocket engines. In addition to representation by multimedia concept maps, we plan to consider linking vast bodies of text (and other media) by hypertexting methods.

Materials science experiments under microgravity increasingly rely on advanced optical systems to determine the physical properties of the samples under investigation. This includes video systems with high spatial and temporal resolution. The acquisition, handling, storage and transmission to ground of the resulting video data are very challenging. Since the available downlink data rate is limited, the capability to compress the video data significantly without compromising the data quality is essential. We report on the development of a Digital Video System (DVS) for EML (Electro Magnetic Levitator) which provides real-time video acquisition, high compression using advanced Wavelet algorithms, storage and transmission of a continuous flow of video with different characteristics in terms of image dimensions and frame rates. The DVS is able to operate with the latest generation of high-performance cameras acquiring high resolution video images up to 4Mpixels@60 fps or high frame rate video images up to about 1000 fps@512x512pixels.

A PC-based integrated aid tool has been developed for the analysis and screening of pathological voices. With it the user can simultaneously record speech, electroglottographic (EGG), and videoendoscopic signals, and synchronously edit them to select the most significant segments. These multimedia data are stored on a relational database, together with a patient's personal information, anamnesis, diagnosis, visits, explorations and any other comment the specialist may wish to include. The speech and EGG waveforms are analysed by means of temporal representations and the quantitative measurements of parameters such as spectrograms, frequency and amplitude perturbation measurements, harmonic energy, noise, etc. are calculated using digital signal processing techniques, giving an idea of the degree of hoarseness and quality of the voice register. Within this framework, the system uses a standard protocol to evaluate and build complete databases of voice disorders. The target users of this system are speech and language therapists and ear nose and throat (ENT) clinicians. The application can be easily configured to cover the needs of both groups of professionals. The software has a user-friendly Windows style interface. The PC should be equipped with standard sound and video capture cards. Signals are captured using common transducers: a microphone, an electroglottograph and a fiberscope or telelaryngoscope. The clinical usefulness of the system is addressed in a comprehensive evaluation section.
