An introduction to QR Codes: linking libraries and mobile patrons.  

PubMed

QR codes, or "Quick Response" codes, are two-dimensional barcodes that can be scanned by mobile smartphone cameras. These codes can be used to provide fast access to URLs, telephone numbers, and short passages of text. With the rapid adoption of smartphones, librarians are able to use QR codes to promote services and help library users find materials quickly and independently. This article will explain what QR codes are, discuss how they can be used in the library, and describe issues surrounding their use. A list of resources for generating and scanning QR codes is also provided. PMID:21800986

Effect of Bromocriptine-QR (a Quick-Release Formulation of Bromocriptine Mesylate) on Major Adverse Cardiovascular Events in Type 2 Diabetes Subjects  

PubMed Central

Background Bromocriptine-QR (a quick-release formulation of bromocriptine mesylate), a dopamine D2 receptor agonist, is a US Food and Drug Administrration–approved treatment for type 2 diabetes mellitus (T2DM). A 3070-subject randomized trial demonstrated a significant, 40% reduction in relative risk among bromocriptine-QR-treated subjects in a prespecified composite cardiovascular (CV) end point that included ischemic-related (myocardial infarction and stroke) and nonischemic-related (hospitalization for unstable angina, congestive heart failure [CHF], or revascularization surgery) end points, but did not include cardiovascular death as a component of this composite. The present investigation was undertaken to more critically evaluate the impact of bromocriptine-QR on cardiovascular outcomes in this study subject population by (1) including CV death in the above-described original composite analysis and then stratifying this new analysis on the basis of multiple demographic subgroups and (2) analyzing the influence of this intervention on only the “hard” CV end points of myocardial infarction, stroke, and CV death (major adverse cardiovascular events [MACEs]). Methods and Results Three thousand seventy T2DM subjects on stable doses of ?2 antidiabetes medications (including insulin) with HbA1c ?10.0 (average baseline HbA1c=7.0) were randomized 2:1 to bromocriptine-QR (1.6 to 4.8 mg/day) or placebo for a 52-week treatment period. Subjects with heart failure (New York Heart Classes I and II) and precedent myocardial infarction or revascularization surgery were allowed to participate in the trial. Study outcomes included time to first event for each of the 2 CV composite end points described above. The relative risk comparing bromocriptine-QR with the control for the cardiovascular outcomes was estimated as a hazard ratio with 95% confidence interval on the basis of Cox proportional hazards regression. The statistical significance of any between-group difference in the cumulative percentage of CV events over time (derived from a Kaplan–Meier curve) was determined by a log-rank test on the intention-to-treat population. Study subjects were in reasonable metabolic control, with an average baseline HbA1c of 7.0±1.1, blood pressure of 128/76±14/9, and total and LDL cholesterol of 179±42 and 98±32, respectively, with 88%, 77%, and 69% of subjects being treated with antidiabetic, antihypertensive, and antihyperlipidemic agents, respectively. Ninety-one percent of the expected person-year outcome ascertainment was obtained in this study. Respecting the CV-inclusive composite cardiovascular end point, there were 39 events (1.9%) among 2054 bromocriptine-QR-treated subjects versus 33 events (3.2%) among 1016 placebo subjects, yielding a significant, 39% reduction in relative risk in this end point with bromocriptine-QR exposure (P=0.0346; log-rank test) that was not influenced by age, sex, race, body mass index, duration of diabetes, or preexisting cardiovascular disease. In addition, regarding the MACE end point, there were 14 events (0.7%) among 2054 bromocriptine-QR-treated subjects and 15 events (1.5%) among 1016 placebo-treated subjects, yielding a significant, 52% reduction in relative risk in this end point with bromocriptine-QR exposure (P<0.05; log-rank test). Conclusions These findings reaffirm and extend the original observation of relative risk reduction in cardiovascular adverse events among type 2 diabetes subjects treated with bromocriptine-QR and suggest that further investigation into this impact of bromocriptine-QR is warranted.

Security printing of covert quick response codes using upconverting nanoparticle inks.  

PubMed

Counterfeiting costs governments and private industries billions of dollars annually due to loss of value in currency and other printed items. This research involves using lanthanide doped ?-NaYF(4) nanoparticles for security printing applications. Inks comprised of Yb(3+)/Er(3+) and Yb(3+)/Tm(3+) doped ?-NaYF(4) nanoparticles with oleic acid as the capping agent in toluene and methyl benzoate with poly(methyl methacrylate) (PMMA) as the binding agent were used to print quick response (QR) codes. The QR codes were made using an AutoCAD file and printed with Optomec direct-write aerosol jetting(®). The printed QR codes are invisible under ambient lighting conditions, but are readable using a near-IR laser, and were successfully scanned using a smart phone. This research demonstrates that QR codes, which have been used primarily for information sharing applications, can also be used for security purposes. Higher levels of security were achieved by printing both green and blue upconverting inks, based on combinations of Er(3+)/Yb(3+) and Tm(3+)/Yb(3+), respectively, in a single QR code. The near-infrared (NIR)-to-visible upconversion luminescence properties of the two-ink QR codes were analyzed, including the influence of NIR excitation power density on perceived color, in term of the CIE 1931 chromaticity index. It was also shown that this security ink can be optimized for line width, thickness and stability on different substrates. PMID:22968045

Experimental QR code optical encryption: noise-free data recovering.  

PubMed

We report, to our knowledge for the first time, the experimental implementation of a quick response (QR) code as a "container" in an optical encryption system. A joint transform correlator architecture in an interferometric configuration is chosen as the experimental scheme. As the implementation is not possible in a single step, a multiplexing procedure to encrypt the QR code of the original information is applied. Once the QR code is correctly decrypted, the speckle noise present in the recovered QR code is eliminated by a simple digital procedure. Finally, the original information is retrieved completely free of any kind of degradation after reading the QR code. Additionally, we propose and implement a new protocol in which the reception of the encrypted QR code and its decryption, the digital block processing, and the reading of the decrypted QR code are performed employing only one device (smartphone, tablet, or computer). The overall method probes to produce an outcome far more attractive to make the adoption of the technique a plausible option. Experimental results are presented to demonstrate the practicality of the proposed security system. PMID:24978277

Raman spectroscopy: in vivo quick response code of skin physiological status.  

PubMed

Dermatologists need to combine different clinically relevant characteristics for a better understanding of skin health. These characteristics are usually measured by different techniques, and some of them are highly time consuming. Therefore, a predicting model based on Raman spectroscopy and partial least square (PLS) regression was developed as a rapid multiparametric method. The Raman spectra collected from the five uppermost micrometers of 11 healthy volunteers were fitted to different skin characteristics measured by independent appropriate methods (transepidermal water loss, hydration, pH, relative amount of ceramides, fatty acids, and cholesterol). For each parameter, the obtained PLS model presented correlation coefficients higher than R2=0.9. This model enables us to obtain all the aforementioned parameters directly from the unique Raman signature. In addition to that, in-depth Raman analyses down to 20 ?m showed different balances between partially bound water and unbound water with depth. In parallel, the increase of depth was followed by an unfolding process of the proteins. The combinations of all these information led to a multiparametric investigation, which better characterizes the skin status. Raman signal can thus be used as a quick response code (QR code). This could help dermatologic diagnosis of physiological variations and presents a possible extension to pathological characterization. PMID:24839943

How much domestic quick response manufacturing can a business afford?  

NASA Astrophysics Data System (ADS)

Employment in the U.S. apparel industry has declined dramatically since the 1960s. Will it fall inexorably to zero, or is there some base level that can endure? If so, what strategic characteristics are required to survive? There is considerable interest in Quick Response Manufacturing (QRM), not only as a reason to support domestic manufacturing, but also as part of the larger goal of reducing supply chain costs. However, since Domestic Manufacturing is more expensive, why should anyone bother considering it? This paper presents an analytical model of a team approach that includes both domestic and offshore manufacturing. Despite the additional costs associated with U.S. manufacturing, our model predicts that including a domestic contractor is legitimate and cost effective. However, the alliance must be genuinely cooperative. A partnership has to be established early in the retailer's planning cycle, and the manufacturer should participate in the planning. Also, sharing data and making timely decisions imposes a strategic business approach, and the model allows us to describe the characteristic roles and capabilities required. Using this model for guidance, we anticipate that retailers will have the stock to satisfy more customers with fewer markdowns, while manufacturers will see increased margins and lower inventories.

QR Images: Optimized Image Embedding in QR Codes.  

PubMed

This paper introduces the concept of QR images, an automatic method to embed QR codes into color images with bounded probability of detection error. These embeddings are compatible with standard decoding applications and can be applied to any color image with full area coverage. The QR information bits are encoded into the luminance values of the image, taking advantage of the immunity of QR readers against local luminance disturbances. To mitigate the visual distortion of the QR image, the algorithm utilizes halftoning masks for the selection of modified pixels and nonlinear programming techniques to locally optimize luminance levels. A tractable model for the probability of error is developed and models of the human visual system are considered in the quality metric used to optimize the luminance levels of the QR image. To minimize the processing time, the optimization techniques proposed to consider the mechanics of a common binarization method and are designed to be amenable for parallel implementations. Experimental results show the graceful degradation of the decoding rate and the perceptual quality as a function the embedding parameters. A visual comparison between the proposed and existing methods is presented. PMID:24808410

Design of a quick response SMA actuated segmented nut for space release applications  

NASA Astrophysics Data System (ADS)

Spacecrafts require a variety of separation and release devices to accommodate separation from the launch vehicle or deployment of heat radiation panels, solar arrays and other appendages. In order to overcome drawbacks of the current release devices, this paper proposes a design scheme of release device with a form of segmented nut and actuated with SMA (Shape Memory Alloy) wire. In order to validate the release device's function and performance, ground tests including single device response time tests, synchronous tests of two devices, fatigue life tests were carried out. Tests results show that the innovative space release device developed in this paper owning the advantages of small size, quick response, long fatigue life, high simultaneity and auto-reset has a potential use in space engineering.

Contourlet based image watermarking using QR decomposition  

NASA Astrophysics Data System (ADS)

The paper presents an image watermarking algorithm based on Contourlet Transform (CT) and QR factorization method. Contourlet Transform is used to transform both the cover and watermark image into subbands. The watermarking is applied to the Contourlet Transform as the human visual system is comparatively less sensitive to edges of the image. The low frequency coefficients of an image contain the highest energy. Thus the lowest frequency coefficients of the contourlet transformed original and watermark image are selected for watermarking. The selected coefficients are then decomposed using QR factorization method. The QR factorized coefficients of watermark image is embedded into the QR factorized original image values. Inverse QR and inverse CT is then applied on the watermark embedded coefficients of image to obtain the watermarked image. Experimental results show that the proposed algorithm is a better technique as compared to other watermarking schemes based on Contourlet Transform. The proposed watermarking scheme is imperceptible and robust against image processing attacks such as Gaussian noise, scaling, compression, salt and pepper noise.

Pharmacogenomics in the pocket of every patient? A prototype based on quick response codes  

PubMed Central

A sizable fraction of patients experiences adverse drug events or lack of drug efficacy. A part of this variability in drug response can be explained by genetic differences between patients. However, pharmacogenomic data as well as computational clinical decision support systems for interpreting such data are still unavailable in most healthcare settings. We address this problem by introducing the medicine safety code (MSC), which captures compressed pharmacogenomic data in a two-dimensional barcode that can be carried in a patient's wallet. We successfully encoded data about 385 genetic polymorphisms in MSC and were able to decode and interpret MSC quickly with common mobile devices. The MSC could make individual pharmacogenomic data and decision support available in a wide variety of healthcare settings without the set up of large-scale infrastructures or centralized databases.

Concepts, technology, and operations for a quick response, highly maneuverable launch vehicle  

NASA Technical Reports Server (NTRS)

Preliminary results from the NASA orbit-on-demand study are used to identify major technology issues for development of a quick response vehicle. Reasonable vehicles are found to require significant advances in propulsion, structures, materials, and flight mechanics technology. Vehicle concepts using normal growth technology predicted for the 1990s are compromised by expendable hardware or by unmanageable size and complexity. Operational analyses of the vertical-launch and horizontal-launch takeoff vehicles show that the latter have more inherent operational utility. The supply of liquid hydrogen propellant at alternate sites is a major issue; however, propane may be a viable option for at least one concept. Propellant for orbital maneuvering significantly increases gross weight for many of the concepts. This increase is greater for horizontal-takeoff systems becasue of their larger orbiters.

Quick Response Observed in Solid-State Electrochromic Device with Interfacial Barrier Structure  

NASA Astrophysics Data System (ADS)

A novel structure is proposed for a solid-state electrochromic (EC) device to improve its dynamic response. The proposed device is composed of an indium-tin-oxide (ITO)-coated glass substrate, an amorphous thin WO3 film, a very thin SiO2 film, an electrolytic thin Ta2O5 film, and a semitransparent top electrode. The experimental results show that the EC response significantly improves compared with the conventional device with no SiO2 films, and that the response time decreases to 100 ms at a bias voltage of 3 V. This value is close to a practical level for actual applications. This improvement is interpreted to be a result of carrier accumulation produced by the SiO2 film followed by an increase in the proton generation rate leading to fast EC coloration. The observed quick response is also discussed in relation to the EC efficiency. The charge accumulation approach is very useful for development of a fast and reliable solid-state EC device.

A quick response four decade logarithmic high-voltage stepping supply  

NASA Technical Reports Server (NTRS)

An improved high-voltage stepping supply, for space instrumentation is described where low power consumption and fast settling time between steps are required. The high-voltage stepping supply, utilizing an average power of 750 milliwatts, delivers a pair of mirror images with 64 level logarithmic outputs. It covers a four decade range of + or - 2500 to + or - 0.29 volts having an output stability of + or - 0.5 percent or + or - 20 millivolts for all line load and temperature variations. The supply provides a typical step setting time of 1 millisecond with 100 microseconds for the lower two decades. The versatile design features of the high-voltage stepping supply provides a quick response staircase generator as described or a fixed voltage with the option to change levels as required over large dynamic ranges without circuit modifications. The concept can be implemented up to + or - 5000 volts. With these design features, the high-voltage stepping supply should find numerous applications where charged particle detection, electro-optical systems, and high voltage scientific instruments are used.

A QR code based zero-watermarking scheme for authentication of medical images in teleradiology cloud.  

PubMed

Healthcare institutions adapt cloud based archiving of medical images and patient records to share them efficiently. Controlled access to these records and authentication of images must be enforced to mitigate fraudulent activities and medical errors. This paper presents a zero-watermarking scheme implemented in the composite Contourlet Transform (CT)-Singular Value Decomposition (SVD) domain for unambiguous authentication of medical images. Further, a framework is proposed for accessing patient records based on the watermarking scheme. The patient identification details and a link to patient data encoded into a Quick Response (QR) code serves as the watermark. In the proposed scheme, the medical image is not subjected to degradations due to watermarking. Patient authentication and authorized access to patient data are realized on combining a Secret Share with the Master Share constructed from invariant features of the medical image. The Hu's invariant image moments are exploited in creating the Master Share. The proposed system is evaluated with Checkmark software and is found to be robust to both geometric and non geometric attacks. PMID:23970943

Modeling of Qr Sensors for Optimized Explosives Detection  

NASA Astrophysics Data System (ADS)

Quadrupole Resonance (QR) sensors have the unique capability of detecting explosives with remarkably high detection rates and low number of false alarms. The sensitivity of a QR-based sensor in inductive detection can be assessed in terms of the signal-to-noise ratio (SNR), which determines the Receiver Operating Characteristics (ROC) curves of the detector and provides a fundamental limitation to the performance of the QR explosive detection system. The main goal of the QR sensor design is, therefore, to maximize the SNR to achieve the highest possible detection performance with the lowest number of nuisances.

Quick concurrent responses to global and local cognitive information underlie intuitive understanding in board-game experts.  

PubMed

Experts have the superior cognitive capability of quickly understanding complex information in their domain; however, little is known about the neural processes underlying this ability. Here, using a board game named shogi (Japanese chess), we investigated the brain activity in expert players that was involved in their quick understanding of board-game patterns. The frontal area responded only to meaningful game positions, whereas the temporal area responded to both game and random positions with the same latency (200?ms). Subsequent to these quick responses, the temporal and parietal areas responded only to game positions, with a latency of 700?ms. During the responses, enhanced phase synchronization between these areas was observed. Thus, experts first responded to global cognitive information that was specific to game positions and to local cognitive information that was common to game and random positions concurrently. These types of information were integrated via neural synchronization at the posterior areas. As these properties were specific to experts, much of the experts' advantage in understanding game positions occurred within 1?s of perception. PMID:25081320

Quick Response Observed in Solid-State Electrochromic Device with Interfacial Barrier Structure  

Microsoft Academic Search

A novel structure is proposed for a solid-state electrochromic (EC) device to improve its dynamic response. The proposed device is composed of an indium-tin-oxide (ITO)-coated glass substrate, an amorphous thin WO3 film, a very thin SiO2 film, an electrolytic thin Ta2O5 film, and a semitransparent top electrode. The experimental results show that the EC response significantly improves compared with the

Electroswitching of emission and coloration with quick response and high reversibility in an electrochemical cell.  

PubMed

No fade to grey: Electroswitching of emission and coloration was achieved for a combination of a luminescent Eu(III) complex and an electrochromic molecule of diheptyl viologen (HV(2+)), indicating that such a combination could be used as a display material with dual emissive and reflective modes. The Prussian blue (PB)-modified electrode improved the response time and reversibility for the switching of emission and coloration, by acting as a counter electrode for the electrochromism of HV(2+).

Context-based automatic reconstruction and texturing of 3D urban terrain for quick-response tasks  

NASA Astrophysics Data System (ADS)

Highly detailed 3D urban terrain models are the base for quick response tasks with indispensable human participation, e.g., disaster management. Thus, it is important to automate and accelerate the process of urban terrain modeling from sensor data such that the resulting 3D model is semantic, compact, recognizable, and easily usable for training and simulation purposes. To provide essential geometric attributes, buildings and trees must be identified among elevated objects in digital surface models. After building ground-plan estimation and roof details analysis, images from oblique airborne imagery are used to cover building faces with up-to-date texture thus achieving a better recognizability of the model. The three steps of the texturing procedure are sensor pose estimation, assessment of polygons projected into the images, and texture synthesis. Free geographic data, providing additional information about streets, forest areas, and other topographic object types, suppress false alarms and enrich the reconstruction results.

Reliability, validity and responsiveness of the French version of the questionnaire Quick Disability of the Arm, Shoulder and Hand in shoulder disorders.  

PubMed

We assessed the reliability, validity and responsiveness of the French short version of the scale Disability of the Arm, Shoulder and Hand-Disability/Symptom (F-QuickDASH-D/S) in patients with shoulder disorders. We extracted QuickDASH item responses from the responses to the full-length DASH questionnaire completed by 153 patients. In addition to collecting demographic and clinical data, subjective assessment of activities of daily living (ADL), active range of motion (ROM), and measurement of abduction strength (strength) were recorded by use of the Constant scale. Cronbach's alpha coefficient was 0.89. The intraclass correlation coefficient was 0.94, which suggested excellent test-retest reliability. Correlation of the F-QuickDASH-D/S score with scores for F-DASH-D/S (r=0.96), handicap (r=0.79), ADL (r=-0.73), pain during activities (r=0.63), strength (r=-0.58), pain at rest (r=0.57) and ROM (r=-0.51) indicated good construct validity. Factor analysis identified 2 factors accounting for 59.1% of the variance. The responsiveness of F-QuickDASH-D/S was excellent, with standardized response mean and effect size values of 1.09 and 1.23, respectively. The F-QuickDASH-D/S has good reliability, construct validity and responsiveness. The strong correlation of its score with the full-length DASH-D/S scale score suggests that the QuickDASH-D/S could be the preferred scale because it is easier to use. PMID:18436467

2001 QR322: a dynamically unstable Neptune Trojan?  

NASA Astrophysics Data System (ADS)

Since early work on the stability of the first Neptunian Trojan, 2001 QR322, suggested that it was a dynamically stable, primordial body, it has been assumed that this applies to both that object and its more recently discovered brethren. However, it seems that things are no longer so clear-cut. In this work, we present the results of detailed dynamical simulations of the orbital behaviour of 2001 QR322. Using an ephemeris for the object that has significantly improved since earlier works, we follow the evolution of 19683 test particles, placed on orbits within the observational error ellipse of 2001 QR322's orbit, for a period of 1Gyr. We find that majority of these `clones' of 2001 QR322 are dynamically unstable, exhibiting a near-exponential decay from both the Neptunian Trojan cloud (decay half-life of ~550Myr) and the Solar system (decay half-life of ~590Myr). The stability of the object within Neptune's Trojan cloud is found to be strongly dependent on the initial semimajor axis used, with these objects located at a >= 30.30au being significantly less stable than those interior to this value, as a result of their having initial libration amplitudes very close to a critical threshold dividing regular and irregular motion, located at ~70°-75° (full extent of angular motion). This result suggests that if 2001 QR322 is a primordial Neptunian Trojan, it must be a representative of a population that was once significantly larger than that we see today and adds weight to the idea that the Neptune Trojans may represent a significant source of objects moving on unstable orbits between the giant planets (the Centaurs).

The differentially regulated genes TvQR1 and TvPirin of the parasitic plant Triphysaria exhibit distinctive natural allelic diversity  

PubMed Central

Background Plant parasitism represents an extraordinary interaction among flowering plants: parasitic plants use a specialized organ, the haustorium, to invade the host vascular system to deprive host plants of water and nutrients. Various compounds present in exudates of host plants trigger haustorium development. The two most effective haustorium inducing factors (HIFs) known for the parasitic plant Triphysaria versicolor (T. versicolor) are peonidin, an antioxidant flavonoid, and 2,6-dimethoxybenzoquinone (DMBQ), an oxidative stress agent. To date, two genes involved in haustorium initiation in T. versicolor have been identified: TvQR1, a quinone oxidoreductase that generates the active HIF from DMBQ, and TvPirin, a transcription co-factor that regulates several other DMBQ- responsive and –non-responsive genes. While the expression of these genes in response to DMBQ is well characterized, their expression in response to peonidin is not. In addition, the pattern of polymorphisms in these genes is unknown, even though nucleotide changes in TvQR1 and TvPirin may have contributed to the ability of T. versicolor to develop haustoria. To gain insights into these aspects, we investigated their transcriptional responses to HIFs and non-HIF and their natural nucleotide diversity. Results Here we show that TvQR1 and TvPirin are transcriptionally upregulated by both DMBQ and peonidin in T. versicolor roots. Yet, while TvQR1 also responded to juglone, a non-HIF quinone with toxicity comparable to that of DMBQ, TvPirin did not. We further demonstrate that TvPirin encodes a protein shorter than the one previously reported. In the T. versicolor natural population of Northern California, TvQR1 exhibited remarkably higher molecular diversity and more recombination events than TvPirin, with the highest non-synonymous substitution rate in the substrate recognition and catalytic domain of the TvQR1 protein. Conclusion Our results suggest that TvQR1 and TvPirin have most likely evolved highly distinct roles for haustorium formation. Unlike TvPirin, TvQR1 might have been under diversifying selection to maintain a diverse collection of polymorphisms, which might be related to the recognition of an assortment of HIF and non-HIF quinones as substrates for successful haustorial establishment in a wide range of host plants.

Utilizing QR decomposition for solving singular fuzzy linear systems  

NASA Astrophysics Data System (ADS)

In this paper, we study the solution of n × n fuzzy linear system Ãx = ˜b where A is a singular crisp matrix, ˜x and ˜b are vectors of fuzzy numbers. We first convert the fuzzy linear system Ãx = ˜b to 2n × 2n crisp linear system SX = Y. where S is a singular matrix. We then apply the Drazin inverse to solve the 2n × 2n crisp linear system SX = Y. To investigate the effect of Drazin inverse, we apply the QR decomposition method. Several numerical examples are discussed.

ZnO/TiO2 composite nanofibers are synthesized by an electrospinning method and characterized by x-ray diffraction, scanning electron microscopy, and transmission electron microscopy. A micro humidity sensor is fabricated by spinning the precursors of these nanofibers on a ceramic substrate with Ag-Pd interdigitated electrodes. Humidity sensing investigation reveals that this micro sensor offers high sensitivity and quick response/recovery at an operating frequency of 100Hz. The corresponding impedance changes more than four orders of magnitude within the whole humidity range from 10% to 90% relative humidity (RH), and the response and recovery times are about 4 and 12 s, respectively. The maximum hysteresis is around 2% RH. The humidity sensing mechanism is also discussed based on the nanofiber structure and morphology.

QR-LRL Signal Detection for Spatially Multiplexed MIMO Systems  

NASA Astrophysics Data System (ADS)

The performance of the ordered successive interference cancellation (OSIC) signal detection method is well known to depend on the successful detection of the first layer. In a previous work, in an effort to mitigate the error propagation effect, all the constellation points were tried as the first layer symbol, thereby achieving a better performance. In this letter, we show that the selection of the first layer impacts the error performance significantly, and based on the observation, we propose a novel signal detection method QR-LRL. In the proposed work, the least reliable layer (LRL) is chosen to be the first layer, which is shown to be the best choice in terms of noise enhancement in detecting the other layers. Also, we discuss Log Likelihood Ratio (LLR) computation when the proposed method is used. Computer simulations confirm the efficacy of the proposed method.

Polarization demultiplexing by recursive least squares constant modulus algorithm based on QR decomposition  

NASA Astrophysics Data System (ADS)

Recursive least squares constant modulus algorithm based on QR decomposition (QR-RLS-CMA) is first proposed as the polarization demultiplexing method. We compare its performance with the stochastic gradient descent constant modulus algorithm (SGD-CMA) and the recursive least squares constant modulus algorithm (RLS-CMA) in a polarization-division-multiplexing system with coherent detection. It is demonstrated that QR-RLS-CMA is an efficient demultiplexing algorithm which can avoid the problem of step-length choice in SGD-CMA. Meanwhile, it also has better symbol error rate (SER) performance and more stable convergence property.

QuickTox Kit for QuickScan DON (Vomitoxin).  

PubMed

The QuickTox Kit for QuickScan DON (Vomitoxin) uses lateral flow technology and a reader-based system for the quantification of deoxynivalenol (DON, vomitoxin) residues in cereal grain commodities. The present work was performed to obtain AOAC Research Institute Performance Tested MethodsM certification for testing wheat, maize, wheat bran, wheat flour, and barley samples with DON contamination levels as high as 5 ppm. Assay performance was examined using naturally contaminated and spiked samples in internal and independent laboratory evaluations and was compared to previously established acceptance criteria. Performance was evaluated with direct regard to linearity, matrix, selectivity, robustness, and stability. All data points in all studies were within the ranges defined in the acceptance criteria. The assay exhibited a linear dose response over the range tested, 0-5.0 ppm, with R2 values exceeding 0.97. RSD of repeatability, or RSDr, values for results ranged from 3.12 to 16.01% across all tested commodities and levels. Assay results were not affected by the presence of other common mycotoxins: aflatoxin B1, fumonisin B1, ochratoxin A, or zearalenone. Selectivity for modified DON was examined, specifically 15-acetyl DON, 3-acetyl DON, DON-3-glucoside, and another tricothecene, nivalenol; all were detected. The assay produced acceptable results in robustness studies when assay timing, temperature, and volume were covaried. The QuickTox Kit for QuickScan DON (Vomitoxin) assay is a convenient and reliable method for determination of DON in grain commodities. PMID:24282939

Optical encryption and QR codes: secure and noise-free information retrieval.  

PubMed

We introduce for the first time the concept of an information "container" before a standard optical encrypting procedure. The "container" selected is a QR code which offers the main advantage of being tolerant to pollutant speckle noise. Besides, the QR code can be read by smartphones, a massively used device. Additionally, QR code includes another secure step to the encrypting benefits the optical methods provide. The QR is generated by means of worldwide free available software. The concept development probes that speckle noise polluting the outcomes of normal optical encrypting procedures can be avoided, then making more attractive the adoption of these techniques. Actual smartphone collected results are shown to validate our proposal. PMID:23482108

gC1qR Expression in Normal and Pathologic Human Tissues  

PubMed Central

The gC1qR (i.e., gC1q receptor, gC1q binding protein, p32, p33) is a multifunctional cellular protein that interacts with components of the complement, kinin, and coagulation cascades and select microbial pathogens. Enhanced gC1qR expression has been reported in adenocarcinomas arising in a variety of organs. The present study compared gC1qR expression in normal, inflammatory, dysplastic, and malignant tissue of epithelial and mesenchymal origin. gC1qR expression was visualized in tissue sections by immunohistochemistry using the 60.11 monoclonal antibody (i.e., IgG1 mouse monoclonal antibody directed against gC1qR) and the UltraVision LP Detection System. Sections were counterstained with hematoxylin and examined by light microscopy. Strongest gC1qR expression was noted in epithelial tumors of breast, prostate, liver, lung, and colon, as well as in squamous and basal cell carcinoma of the skin. However, increased gC1qR staining was appreciated also in inflammatory and proliferative lesions of the same cell types, as well as in normal continuously dividing cells. In contrast, tumors of mesenchymal origin generally stained weakly, with the exception of osteoblasts, which stained in both benign and malignant tissues. The data suggest that increased gC1qR expression may be a marker of benign and pathologic cell proliferation, particularly in cells of epithelial origin, with potential diagnostic and therapeutic applications.

Evolutionary profiles from the QR factorization of multiple sequence alignments  

PubMed Central

We present an algorithm to generate complete evolutionary profiles that represent the topology of the molecular phylogenetic tree of the homologous group. The method, based on the multidimensional QR factorization of numerically encoded multiple sequence alignments, removes redundancy from the alignments and orders the protein sequences by increasing linear dependence, resulting in the identification of a minimal basis set of sequences that spans the evolutionary space of the homologous group of proteins. We observe a general trend that these smaller, more evolutionarily balanced profiles have comparable and, in many cases, better performance in database searches than conventional profiles containing hundreds of sequences, constructed in an iterative and computationally intensive procedure. For more diverse families or superfamilies, with sequence identity <30%, structural alignments, based purely on the geometry of the protein structures, provide better alignments than pure sequence-based methods. Merging the structure and sequence information allows the construction of accurate profiles for distantly related groups. These structure-based profiles outperformed other sequence-based methods for finding distant homologs and were used to identify a putative class II cysteinyl-tRNA synthetase (CysRS) in several archaea that eluded previous annotation studies. Phylogenetic analysis showed the putative class II CysRSs to be a monophyletic group and homology modeling revealed a constellation of active site residues similar to that in the known class I CysRS.

Randomized Clinical Trial of Quick-Release Bromocriptine Among Patients With Type 2 Diabetes on Overall Safety and Cardiovascular Outcomes  

PubMed Central

OBJECTIVE Quick-release bromocriptine (bromocriptine-QR), a D2 dopamine receptor agonist, is indicated as a treatment for type 2 diabetes. The Cycloset Safety Trial, a 52-week, randomized, double-blind, multicenter trial, evaluated the overall safety and cardiovascular safety of this novel therapy for type 2 diabetes. RESEARCH DESIGN AND METHODS A total of 3,095 patients with type 2 diabetes were randomized 2:1 to bromocriptine-QR or placebo in conjunction with the patient's usual diabetes therapy (diet controlled only or up to two antidiabetes medications, including insulin). The all-cause–safety end point was the occurrence of any serious adverse event (SAE), with a hazard ratio (HR) noninferiority margin of 1.5. In a prespecified analysis, the frequency of cardiovascular disease (CVD) events defined as a composite of myocardial infarction, stroke, coronary revascularization, and hospitalization for angina or congestive heart failure was evaluated using modified intent-to-treat analysis (clinicaltrials.gov, NCT00377676). RESULTS In the bromocriptine-QR group, 176 (8.6%) people reported SAEs compared with 98 (9.6%) in the placebo group (HR 1.02 [96% one-sided CI 1.27]). Fewer people reported a CVD end point in the bromocriptine-QR group versus the placebo group (37 [1.8%] vs. 32 [3.2%], respecively) (HR 0.60 [95% two-sided CI 0.35–0.96]). Nausea was the most commonly reported adverse event in the bromocriptine-QR group. CONCLUSIONS The frequency of SAEs was comparable between the treatment arms. Compared with patients in the placebo arm, fewer patients taking bromocriptine-QR experienced a cardiovascular end point.

Mitochondria-targeted antioxidant SkQR1 selectively protects MDR (Pgp 170)-negative cells against oxidative stress.  

PubMed

A conjugate of plastoquinone with decylrhodamine 19 (SkQR1) selectively accumulates in mitochondria of normal and tumor cells. SkQR1 protected the cellular pool of reduced glutathione under oxidative stress. Overexpression of P-glycoprotein (Pgp 170) multidrug resistance pump strongly suppresses accumulation of SkQR1. The inhibitors of Pgp 170 stimulate accumulation of SkQR1 in various cell lines indicating that SkQR1 is a substrate of Pgp 170. The protective effect of SkQR1 against oxidative stress is diminished in the cells overexpressing Pgp 170. It is suggested that mitochondria-targeted antioxidants could selectively protect normal (Pgp 170-negative) cells against the toxic effect of anti-cancer treatments related to oxidative stress.

Context In the National Athletic Trainers' Association position statement, “Acute Management of the Cervical Spine-Injured Athlete,” the technique recommended for face-mask (FM) removal is one that “creates the least head and neck motion, is performed most quickly, is the least difficult, and carries the least chance of failure.” Industrial and technological advances in football helmet design and FM attachment systems might influence the efficacy of emergency FM removal. Objective To examine the removal times and success rates of the Quick Release (QR) Face Guard Attachment System (Riddell Sports, Inc, Elyria, OH) throughout and at the conclusion of 1 season of play by a National Collegiate Athletic Association Division III football team competing in the Midwest. Design Controlled laboratory study. Setting College laboratory. Patients or Other Participants A total of 69 randomly selected Revolution IQ (Riddell Sports, Inc) football helmets fitted with the QR system were used. Intervention(s) Each helmet was secured to a spine board, and investigators attempted to remove both of the QR side clips from the helmet with the Riddell insertion tool. Main Outcome Measure(s) Dependent variables included total time for removal of both QR side clips from the FM and success rate for removal of both side clips. Results The overall success rate for removal of both clips was 94.8% (164/173), whereas the mean times for removal of both clips ranged from 9.92 ± 12.06 seconds to 16.65 ± 20.97 seconds over 4 trial sessions. We found no differences among mean times for trial sessions throughout the season of play among the same helmets or among different helmets (P > .05). Conclusions Removal time and success rate of the Riddell QR were satisfactory during and after 1 season of play despite use in various temperatures and precipitation.

Quick-release medical tape  

PubMed Central

Medical tape that provides secure fixation of life-sustaining and -monitoring devices with quick, easy, damage-free removal represents a longstanding unmet medical need in neonatal care. During removal of current medical tapes, crack propagation occurs at the adhesive–skin interface, which is also the interface responsible for device fixation. By designing quick-release medical tape to undergo crack propagation between the backing and adhesive layers, we decouple removal and device fixation, enabling dual functionality. We created an ordered adhesive/antiadhesive composite intermediary layer between the medical tape backing and adhesive for which we achieve tunable peel removal force, while maintaining high shear adhesion to secure medical devices. We elucidate the relationship between the spatial ordering of adhesive and antiadhesive regions to create a fully tunable system that achieves strong device fixation and quick, easy, damage-free device removal. We also described ways of neutralizing the residual adhesive on the skin and have observed that thick continuous films of adhesive are easier to remove than the thin islands associated with residual adhesive left by current medical tapes.

Quinone reductase (QR) inducers from Andrographis paniculata and identification of molecular target of andrographolide.  

PubMed

In the present study, it was demonstrated that the petroleum extract of Andrographis paniculata (AP) had quinone reductase (QR) inducing activity, which might be attributed to the modification of key cysteine residues in Keap1 by Michael addition acceptors (MAAs) in it. To screen MAAs in AP, glutathione (GSH) was employed, and a LC/MS/MS method was implied. Three compounds, andrographoside, andrographolide, 14-deoxy-14,15-dehydroandrographolide were revealed could well conjugated with GSH. Then, andrographolide along with 4 new and 14 known compounds were isolated to conduct QR induction evaluation, and the CD (the concentration required to double the activity of QR) value of andrographolide is 1.43?M. The QR induce activity of andrographolide might be attributed to its targeting multiple cysteine residues in Keap1, therefore, the alkylation of Keap1 by andrographolide was further studied and the result showed that four cysteine residues: Cys77, Cys151, Cys273 and Cys368 were alkylated, which indicated that Keap1 is a potential target for the QR induce activity of andrographolide.

Quick stop device  

DOEpatents

A quick stop device for abruptly interrupting the cutting of a workpiece by a cutter is disclosed. The quick stop device employs an outer housing connected to an inner workpiece holder by at least one shear pin. The outer housing includes an appropriate shank designed to be received in the spindle of a machine, such as a machine tool. A cutter, such as a drill bit, is mounted in a stationary position and the workpiece, mounted to the workpiece holder, is rotated during engagement with the cutter. A trigger system includes at least one spring loaded punch disposed for movement into engagement with the workpiece holder to abruptly stop rotation of the workpiece holder. This action shears the shear pin and permits continued rotation of the spindle and outer housing without substantially disturbing the chip root formed during cutting.

Optical information encryption based on incoherent superposition with the help of the QR code  

NASA Astrophysics Data System (ADS)

In this paper, a novel optical information encryption approach is proposed with the help of QR code. This method is based on the concept of incoherent superposition which we introduce for the first time. The information to be encrypted is first transformed into the corresponding QR code, and thereafter the QR code is further encrypted into two phase only masks analytically by use of the intensity superposition of two diffraction wave fields. The proposed method has several advantages over the previous interference-based method, such as a higher security level, a better robustness against noise attack, a more relaxed work condition, and so on. Numerical simulation results and actual smartphone collected results are shown to validate our proposal.

Induction of quinone reductase (QR) by withanolides isolated from Physalis angulata L. var. villosa Bonati (Solanaceae).  

PubMed

In the present study, the EtOAc extract of the persistent calyx of Physalis angulata L. var. villosa Bonati (PA) was tested for its potential quinone reductase (QR) inducing activity with glutathione (GSH) as the substrate using an UPLC-ESI-MS method. The result revealed that the PA had electrophiles that could induce quinone reductase (QR) activity, which might be attributed to the modification of the highly reactive cysteine residues in Keap1. Herein, three new withanolides, compounds 3, 6 and 7, together with four known withanolides, compounds 1, 2, 4 and 5 were isolated from PA extract. Their structures were determined by spectroscopic techniques, including (1)H-, (13)C NMR (DEPT), and 2D-NMR (HMBC, HMQC, (1)H, (1)H-COSY, NOESY) experiments, as well as by HR-MS. All the seven compounds were tested for their QR induction activities towards mouse hepa 1c1c7 cells. PMID:24793335

Transmit Antenna Selection for Spatial Multiplexing UWB MIMO Systems Using Sorted QR Decomposition  

NASA Astrophysics Data System (ADS)

In this letter, a post-detection signal to noise ratio (SNR) is considered for transmit antenna selection, when a sorted QR decomposition (SQRD) algorithm is used for signal detection in spatial multiplexing (SM) ultra-wideband (UWB) multiple input multiple output systems. The post-detection SNR expression is obtained using a QR factorization algorithm based on a sorted Gram-Schmidt process. The employed antenna selection criterion is to utilize the largest minimum post-detection SNR value. It is shown via simulations that the antenna selection significantly enhances the BER performance of the SQRD-based SM UWB systems on a log-normal multipath fading channel.

JHAV' - Quick Sort  

NSDL National Science Digital Library

Visualization for Quick Sort. Includes dynamically highlighted pseudo code. Users can select random data, or give their own data. As the presentation progresses, the sub-array processing is shown as branches of a virtual tree. The AV is set up as a series of 'slides' in one pane, and pseudocode in the adjacent pane. As the user steps through the 'slides', the associated pseudocode is highlighted. Occasional questions pop up for the user to answer. This is an exceptionally clear presentation of Quick Sort. The presentation mechanism for showing the subarray processing is effective. The AV is supported by an HTML page that shows complete pseudocode and gives some guidance on using the AV, though the guide questions are not so extensive as for some other JHAV' topics. There are probably too many 'states' being displayed, since each line of pseudocode gets its own slide. This can be a bit tedious. Some pruning of some of the states might help, but this is probably difficult since the slide show gets generated from the data input. Recommended as lecture aide, standalone, self-study suppliment to tutorial or lecture.

Quick release engine cylinder  

DOEpatents

A quick release engine cylinder allows optical access to an essentially unaltered combustion chamber, is suitable for use with actual combustion processes, and is amenable to rapid and repeated disassembly and cleaning. A cylinder member, adapted to constrain a piston to a defined path through the cylinder member, sealingly engages a cylinder head to provide a production-like combustion chamber. A support member mounts with the cylinder member. The support-to-cylinder mounting allows two relationships therebetween. In the first mounting relationship, the support engages the cylinder member and restrains the cylinder against the head. In the second mounting relationship, the cylinder member can pass through the support member, moving away from the head and providing access to the piston-top and head.

Development of Human-Tracking Robot by Using QR Code Recognition  

NASA Astrophysics Data System (ADS)

In this paper, we propose a human-tracking robot that can be used in some commercial establishments, such as airports and factories. Human-tracking process involves four main steps. The first step involves robust personal identification by using QR code recognition. It is the most important step in human tracking. The second step is location detection by shape-based pattern matching in order to determine the position of the QR code when the human being tracked moves far from the robot. The third step involves auxiliary re-detection by using IR cameras and retroreflectors in case that local detection is difficult in the second step. The fourth step is robot control to maintain the correct distance for human tracking. In a measurement experiment for rate of QR code recognition, it was shown that the rate of QR code recognition was 99.9% and that location detection is robust. In a robot-control experiment, it was shown that the tracking is accurate. During tracking, the robot maintains an appropriate distance from the human.

Implementation of QR-decomposition based on CORDIC for unitary MUSIC algorithm  

NASA Astrophysics Data System (ADS)

The DOA (Direction Of Arrival) estimation with subspace methods such as MUSIC (MUltiple SIgnal Classification) and ESPRIT (Estimation of Signal Parameters via Rotational Invariance Technique) is based on an accurate estimation of the eigenvalues and eigenvectors of covariance matrix. QR decomposition is implemented with the Coordinate Rotation DIgital Computer (CORDIC) algorithm. QRD requires only additions and shifts [6], so it is faster and more regular than other methods. In this article the hardware architecture of an EVD (Eigen Value Decomposition) processor based on TSA (triangular systolic array) for QR decomposition is proposed. Using Xilinx System Generator (XSG), the design is implemented and the estimated logic device resource values are presented for different matrix sizes.

The minimal residual QR-factorization algorithm for reliably solving subset regression problems  

NASA Technical Reports Server (NTRS)

A new algorithm to solve test subset regression problems is described, called the minimal residual QR factorization algorithm (MRQR). This scheme performs a QR factorization with a new column pivoting strategy. Basically, this strategy is based on the change in the residual of the least squares problem. Furthermore, it is demonstrated that this basic scheme might be extended in a numerically efficient way to combine the advantages of existing numerical procedures, such as the singular value decomposition, with those of more classical statistical procedures, such as stepwise regression. This extension is presented as an advisory expert system that guides the user in solving the subset regression problem. The advantages of the new procedure are highlighted by a numerical example.

QR-STEM: Energy and Environment as a Context for Improving QR and STEM Understandings of 6-12 Grade Teachers II. The Quantitative Reasoning  

NASA Astrophysics Data System (ADS)

The Quantitative Reasoning in STEM (QR STEM) project is a state level Mathematics and Science Partnership Project (MSP) with a focus on the mathematics and statistics that underlies the understanding of complex global scientific issues. This session is a companion session to the QR STEM: The Science presentation. The focus of this session is the quantitative reasoning aspects of the project. As students move from understandings that range from local to global in perspective on issues of energy and environment, there is a significant increase in the need for mathematical and statistical conceptual understanding. These understandings must be accessible to the students within the scientific context, requiring the special understandings that are endemic within quantitative reasoning. The QR STEM project brings together interdisciplinary teams of higher education faculty and middle/high school teachers to explore complex problems in energy and environment. The disciplines include life sciences, physics, chemistry, earth science, statistics, and mathematics. These interdisciplinary teams develop open ended performance tasks to implement in the classroom, based on scientific concepts that underpin energy and environment. Quantitative reasoning is broken down into three components: Quantitative Literacy, Quantitative Interpretation, and Quantitative Modeling. Quantitative Literacy is composed of arithmetic concepts such as proportional reasoning, numeracy, and descriptive statistics. Quantitative Interpretation includes algebraic and geometric concepts that underlie the ability to interpret a model of natural phenomena which is provided for the student. This model may be a table, graph, or equation from which the student is to make predictions or identify trends, or from which they would use statistics to explore correlations or patterns in data. Quantitative modeling is the ability to develop the model from data, including the ability to test hypothesis using statistical procedures. We use the term model very broadly, so it includes visual models such as box models, as well as best fit equation models and hypothesis testing. One of the powerful outcomes of the project is the conversation which takes place between science teachers and mathematics teachers. First they realize that though they are teaching concepts that cross their disciplines, the barrier of scientific language within their subjects restricts students from applying the concepts across subjects. Second the mathematics teachers discover the context of science as a means of providing real world situations that engage students in the utility of mathematics as a tool for solving problems. Third the science teachers discover the barrier to understanding science that is presented by poor quantitative reasoning ability. Finally the students are engaged in exploring energy and environment in a manner which exposes the importance of seeing a problem from multiple interdisciplinary perspectives. The outcome is a democratic citizen capable of making informed decisions, and perhaps a future scientist.

gC1qR expression in chimpanzees with resolved and chronic infection: Potential role of HCV core/gC1qR-mediated T cell suppression in the outcome of HCV infection  

SciTech Connect

Chimpanzee is a unique animal model for HCV infection, in which about 50% of infections resolve spontaneously. It has been reported that the magnitude of T cell responses to HCV core in recovered chimpanzees is greater than that in chronically infected ones. However, the mechanism(s) by which the chimpanzees with resolved infection overcome core-mediated immunosuppression remains unknown. In this study, we examined the effect of HCV core on T cell responsiveness in chimpanzees with resolved and chronic HCV infection. We found that core protein strongly inhibited T cell activation and proliferation in chimpanzees with chronic infection, while this inhibition was limited in chimpanzees with resolved infection. Notably, the level of gC1qR, as well as the binding of core protein, on the surface of T cells was lower in recovered chimpanzees when compared to chimpanzees with chronic HCV infection. Intriguingly, the observed differences in gC1qR expression levels and susceptibility to core-induced suppression amongst HCV-chronically infected and recovered chimpanzees were observed prior to HCV challenge, suggesting a possible genetic determination of the outcome of infection. These findings suggest that gC1qR expression on the surface of T cells is crucial for HCV core-mediated T cell suppression and viral clearance, and that represents a novel mechanism by which a virus usurps host machinery for persistence.

A tight and explicit representation of Q in sparse QR factorization  

SciTech Connect

In QR factorization of a sparse m{times}n matrix A (m {ge} n) the orthogonal factor Q is often stored implicitly as a lower trapezoidal matrix H known as the Householder matrix. This paper presents a simple characterization of the row structure of Q, which could be used as the basis for a sparse data structure that can store Q explicitly. The new characterization is a simple extension of a well known row-oriented characterization of the structure of H. Hare, Johnson, Olesky, and van den Driessche have recently provided a complete sparsity analysis of the QR factorization. Let U be the matrix consisting of the first n columns of Q. Using results from, we show that the data structures for H and U resulting from our characterizations are tight when A is a strong Hall matrix. We also show that H and the lower trapezoidal part of U have the same sparsity characterization when A is strong Hall. We then show that this characterization can be extended to any weak Hall matrix that has been permuted into block upper triangular form. Finally, we show that permuting to block triangular form never increases the fill incurred during the factorization.

Detection of circumbinary material in the galactic supersoft X-ray binary QR And  

NASA Astrophysics Data System (ADS)

In an attempt to solve the long-standing quest for the nature of the secondary star in supersoft X-ray binaries, we have obtained phase-resolved high-S/N optical-near-IR spectroscopy and high-resolution near-UV Echelle spectra of the bright galactic supersoft X-ray binary QR And (= RX J0019.8+2156). From the absence of any stellar absorption features in these data we derive a minimum distance d >~800-1300 pc of the binary system. Besides emission lines showing Doppler shifts with the binary orbit, we have detected several broad stationary emission lines which have been identified as forbidden ``coronal-like'' transitions of Fe X, O V, and N V. The material emitting these lines must be distributed axially symmetrically around the binary center of gravity, probably forming an optically thin envelope or a torus surrounding the binary system.

The bents - up to 51 ft high, 28 ft wide, and weighing as much as 58 tons - were cast in 43 configurations to tight tolerances in the sequence in which they were placed, requiring frequent modification of the forms. Modular forms also were used to cast stringer beams to connect the bents. Bent train networks totaling ca 3 miles will link processing and storage facilities at the gas field near Anaco and the marine terminal 40 miles away on the coast near Puerto La Cruz. They are to carry a number of gas and other petroleum product pipes plus utility pipelines and ducts, entering and leaving the trains at various points. Elevating them simplifies altering the lines and eases maintenance. Buried pipelines link the sites.

Quick estimates for hazardous-gas releases  

SciTech Connect

Hazardous gas leaks are a major concern to operators of municipal facilities and to those throughout many segments of the chemical process industries. In the event of a hazardous gas release, a quick estimation of the concentration within the building, and in the area surrounding the building and beyond may help to direct the response actions of all facility personnel. A few simple equations can be used to quickly estimate the hazardous gas concentrations for each of the following cases: Inside a building; within a building cavity; and outside the building cavity. A building cavity refers to the region near the downwind side of the building. In this region, pollutants emitted from an elevated source are mixed rapidly toward the ground due to the aerodynamic turbulence induced by the building. Users of these equations should note the following important assumption: In each of the estimating equations presented the released gas dispersion pattern is assumed to be equivalent to that of a passive gas (i.e., density of a passive gas is equal to that of air).

Pre-Whitening QR-Decomposition Maximum Likelihood Detection for Co-channel Interference Rejection in MIMO Systems  

NASA Astrophysics Data System (ADS)

We describe a co-channel interference rejection scheme that is suitable for QR-decomposition maximum likelihood detection (MLD) in multiple-input and multiple output (MIMO) systems. A pre-whitening matrix for interference rejection is decomposed into a triangular matrix and its Hermitian matrix by using a complex Gaxpy version of the Cholesky algorithm. The decomposed triangular matrix is used as a spatial pre-filter to whiten co-channel interference. Simulation results demonstrate that the proposed scheme can suppress co-channel interference streams at the cost of receive diversity order and achieves better transmission performance than QR-decomposition MLD itself in MIMO channels with co-channel interference.

Incidents when older homebound women tried to reach help quickly.  

PubMed

During a longitudinal study of the experience of reaching help quickly, 34 homebound women (ages 85 to 97) who lived alone reported 106 reach-help-quickly incidents (RHQIs). The purpose of this study was to expand knowledge about RHQIs and intentions relative to them and to compare those facets of experience for subscribers to a personal emergency response system (PERS) and non-subscribers. We used a descriptive phenomenological method to analyze interview data, discerning six types of RHQIs, including finding myself down right here, realizing that I might not be alright after falling and getting up on my own, and realizing that something I cannot explain is or could be wrong with me. Intentions were focused on self-help before help seeking. The overall phenomenon was Handling a Situation When I Am Alone at Home and Probably Need Help Quickly. Practitioners should explore intentions about handling specific types of RHQIs and offer appropriate anticipatory guidance. PMID:23205934

Quick Questions: Create a Survey  

NSDL National Science Digital Library

In this activity, learners will conduct an open-ended survey, and then organize and analyze results. What languages does everyone speak? Whatâs the most common? the least common? Do you think weâd get the same results if we asked this question in a different neighborhood? Start out by posing an open-ended question. Everyone writes answers on stick-on notes and sticks them on a large piece of paper. Explore ways to organize the responses to make sense of them. For instance, if the question is about languages, one approach is to put all the stick-on notes with the same language together. A further step could involve grouping related languages (Eastern European, Southeast Asian, etc.). Available as a web page or downloadable pdf.

Data ingestion into NeQuick 2  

NASA Astrophysics Data System (ADS)

NeQuick 2 is the latest version of the NeQuick ionosphere electron density model developed at the Aeronomy and Radiopropagation Laboratory of the Abdus Salam International Centre for Theoretical Physics (ICTP) - Trieste, Italy with the collaboration of the Institute for Geophysics, Astrophysics and Meteorology of the University of Graz, Austria. It is a quick-run model particularly designed for trans-ionospheric propagation applications that has been conceived to reproduce the median behavior of the ionosphere. To provide 3-D specification of the ionosphere electron density for current conditions, different ionosphere electron density retrieval techniques based on the NeQuick adaptation to GPS-derived Total Electron Content (TEC) data and ionosonde measured peak parameters values have been developed. In the present paper the technique based on the ingestion of global vertical TEC map into NeQuick 2 will be validated and an assessment of the capability of the model to reproduce the ionosphere day-to-day variability will also be performed. For this purpose hourly GPS-derived global vertical TEC maps and hourly foF2 values from about 20 ionosondes corresponding to one month in high solar activity and one month in low solar activity period will be used. Furthermore, the first results concerning the ingestion of space-based GPS-derived TEC data will be presented.

Cell-surface receptor for complement component C1q (gC1qR) is a key regulator for lamellipodia formation and cancer metastasis.  

PubMed

We previously demonstrated that the receptor for the complement component C1q (gC1qR) is a lipid raft protein that is indispensable for adipogenesis and insulin signaling. Here, we provide the first report that gC1qR is an essential component of lamellipodia in human lung carcinoma A549 cells. Cell-surface gC1qR was concentrated in the lamellipodia along with CD44, monosialoganglioside, actin, and phosphorylated focal adhesion kinase in cells stimulated with insulin, IGF-1, EGF, or serum. The growth factor-induced lamellipodia formation and cell migration were significantly decreased in gC1qR-depleted cells, with a concomitant blunt activation of the focal adhesion kinase and the respective receptor tyrosine kinases. Moreover, the gC1qR-depleted cells exhibited a reduced proliferation rate in culture as well as diminished tumorigenic and metastatic activities in grafted mice. We therefore conclude that cell-surface gC1qR regulates lamellipodia formation and metastasis via receptor tyrosine kinase activation. PMID:21536672

High-Molecular-Weight Kininogen Fragments Stimulate the Secretion of Cytokines and Chemokines Through uPAR, Mac-1, and gC1qR in Monocytes  

PubMed Central

Objective Plasma high-molecular-weight kininogen (HK) is cleaved in inflammatory diseases by kallikrein to HKa with release of bradykinin (BK). We postulated a direct link between HKa and cytokine/chemokine release. Methods and Results HKa, but not BK, releases cytokines tumor necrosis factor (TNF)-?, interleukin (IL)-1?, IL-6, and chemokines IL-8 and MCP-1 from isolated human mononuclear cells. At a concentration of 600 nM, glutathione-S-transferase (GST) fusion proteins of kininogen domain 3 (D3), a fragment of domain 3, E7P (aaG255-Q292), HK domain 5 (D5), the D5 recombinant peptides HG (aa K420-D474) and HGK (aa H475-S626) stimulated secretion of IL-1? from mononuclear cells. Monoclonal antibodies (MAbs) specific for D5 or specific for D3 blocked release of IL-1? by HKa, supporting the importance of both domains. Antibodies to HK receptors on leukocytes including Mac-1, LFA-1, uPAR, and C1qR inhibited IL-1? secretion induced by tKa 98%, 89%, 85%, and 62%, respectively. Fractionation of mononuclear cells identified the responsible cell, a blood monocyte. Inhibitors of signaling pathways NFkB, JNK, and p38 but not extracellular signal-regulated kinase (ERK) decreased cytokine release from mononuclear cells. HKa increased the synthesis of IL-1? as deduced by an increase of IL-1? mRNA at 1 to 2 hours. Conclusions HKa domains 3 and 5 may contribute to the pathogenesis of inflammatory diseases by releasing IL-1? from human monocytes using intracellular signaling pathways initiated by uPAR, ?2 integrins and gC1qR.

Protruding disordered loop of gC1qR is specifically exposed and related to antiapoptotic property in germ cell lineage.  

PubMed

We established a monoclonal antibody (MAb), 5G9, with the use of a fixed seminoma tissue from an archival paraffin-embedded specimen, as an immunogen. Without antigen retrieval, positive 5G9-immunohistochemical staining was confined mostly to primordial germ cells, spermatogonia and various germ cell tumors. 5G9 recognized a mitochondrial 32-kD protein with an isoelectric point of pH 4.2, identified as a multifunctional ubiquitous protein, receptor for globular head of C1q (gC1qR), whose epitope was mapped in a disordered loop connecting the beta3 and the beta4 strands. Reflecting the ubiquitous distribution of gC1qR, with antigen retrieval, 5G9 was found reactive to a wide range of normal and tumor tissues. Since several co-precipitated and phosphorylated bands were observed in various human cell lines but not in germ cell tumor cell lines by in vitro phosphorylation assay, we speculate that the epitope of gC1qR is specifically unmasked in the germ cell lineage. By reducing gC1qR by siRNA, a significant increase was observed in the number of apoptotic cells in ITO-II and TCam-2 cell lines, but to a lesser extent in the Colo201 colon cancer cell line, showing an antiapoptotic property of gC1qR in the germ cells. Since protein-protein interaction is partially preserved by fixation, archival paraffin-embedded specimens can be a valuable source of immunogens for generating monoclonal antibodies (MAbs) that recognize tissue-specific protein conformation.

A quick accurate model of nozzle backflow  

NASA Technical Reports Server (NTRS)

Backflow from nozzles is a major source of contamination on spacecraft. If the craft contains any exposed high voltages, the neutral density produced by the nozzles in the vicinity of the craft needs to be known in order to assess the possibility of Paschen breakdown or the probability of sheath ionization around a region of the craft that collects electrons for the plasma. A model for backflow has been developed for incorporation into the Environment-Power System Analysis Tool (EPSAT) which quickly estimates both the magnitude of the backflow and the species makeup of the flow. By combining the backflow model with the Simons (1972) model for continuum flow it is possible to quickly estimate the density of each species from a nozzle at any position in space. The model requires only a few physical parameters of the nozzle and the gas as inputs and is therefore ideal for engineering applications.

System Characterization Results for the QuickBird Sensor  

NASA Technical Reports Server (NTRS)

An overall system characterization was performed on several DigitalGlobe' QuickBird image products by the NASA Applied Research & Technology Project Office (formerly the Applied Sciences Directorate) at the John C. Stennis Space Center. This system characterization incorporated geopositional accuracy assessments, a spatial resolution assessment, and a radiometric calibration assessment. Geopositional assessments of standard georeferenced multispectral products were obtained using an array of accurately surveyed geodetic targets evenly spaced throughout a scene. Geopositional accuracy was calculated in terms of circular error. Spatial resolution of QuickBird panchromatic imagery was characterized based on edge response measurements using edge targets and the tilted-edge technique. Relative edge response was estimated as a geometric mean of normalized edge response differences measured in two directions of image pixels at points distanced from the edge by -0.5 and 0.5 of ground sample distance. A reflectance-based vicarious calibration approach, based on ground-based measurements and radiative transfer calculations, was used to estimate at-sensor radiance. These values were compared to those measured by the sensor to determine the sensor's radiometric accuracy. All imagery analyzed was acquired between fall 2005 and spring 2006. These characterization results were compared to previous years' results to identify any temporal drifts or trends.

ATRC Neutron Detector Testing Quick Look Report  

SciTech Connect

As part of the Advanced Test Reactor (ATR) National Scientific User Facility (NSUF) program, a joint Idaho State University (ISU) / French Alternative Energies and Atomic Energy Commission (CEA) / Idaho National Laboratory (INL) project was initiated in FY-10 to investigate the feasibility of using neutron sensors to provide online measurements of the neutron flux and fission reaction rate in the ATR Critical Facility (ATRC). A second objective was to provide initial neutron spectrum and flux distribution information for physics modeling and code validation using neutron activation based techniques in ATRC as well as ATR during depressurized operations. Detailed activation spectrometry measurements were made in the flux traps and in selected fuel elements, along with standard fission rate distribution measurements at selected core locations. These measurements provide additional calibration data for the real-time sensors of interest as well as provide benchmark neutronics data that will be useful for the ATR Life Extension Program (LEP) Computational Methods and V&V Upgrade project. As part of this effort, techniques developed by Prof. George Imel will be applied by Idaho State University (ISU) for assessing the performance of various flux detectors to develop detailed procedures for initial and follow-on calibrations of these sensors. In addition to comparing data obtained from each type of detector, calculations will be performed to assess the performance of and reduce uncertainties in flux detection sensors and compare data obtained from these sensors with existing integral methods employed at the ATRC. The neutron detectors required for this project were provided to team participants at no cost. Activation detectors (foils and wires) from an existing, well-characterized INL inventory were employed. Furthermore, as part of an on-going ATR NSUF international cooperation, the CEA sent INL three miniature fission chambers (one for detecting fast flux and two for detecting thermal flux) with associated electronics for assessment. In addition, Prof. Imel, ISU, has access to an inventory of Self-Powered Neutron Detectors (SPNDs) with a range of response times as well as Back-to-Back (BTB) fission chambers from prior research he conducted at the Transient REActor Test Facility (TREAT) facility and Neutron RADiography (NRAD) reactors. Finally, SPNDs from the National Atomic Energy Commission of Argentina (CNEA) were provided in connection with the INL effort to upgrade ATR computational methods and V&V protocols that are underway as part of the ATR LEP. Work during fiscal year 2010 (FY10) focussed on design and construction of Experiment Guide Tubes (EGTs) for positioning the flux detectors in the ATRC N-16 locations as well as obtaining ATRC staff concurrence for the detector evaluations. Initial evaluations with CEA researchers were also started in FY10 but were cut short due to reactor reliability issues. Reactor availability issues caused experimental work to be delayed during FY11/12. In FY13, work resumed; and evaluations were completed. The objective of this "Quick Look" report is to summarize experimental activities performed from April 4, 2013 through May 16, 2013.

Steric antisense inhibition of AMPA receptor Q/R editing reveals tight coupling to intronic editing sites and splicing  

PubMed Central

Adenosine-to-Inosine (A-to-I) RNA editing is a post-transcriptional mechanism, evolved to diversify the transcriptome in metazoa. In addition to wide-spread editing in non-coding regions protein recoding by RNA editing allows for fine tuning of protein function. Functional consequences are only known for some editing sites and the combinatorial effect between multiple sites (functional epistasis) is currently unclear. Similarly, the interplay between RNA editing and splicing, which impacts on post-transcriptional gene regulation, has not been resolved. Here, we describe a versatile antisense approach, which will aid resolving these open questions. We have developed and characterized morpholino oligos targeting the most efficiently edited site—the AMPA receptor GluA2 Q/R site. We show that inhibition of editing closely correlates with intronic editing efficiency, which is linked to splicing efficiency. In addition to providing a versatile tool our data underscore the unique efficiency of a physiologically pivotal editing site.

Zebrafish Adar2 Edits the Q/R Site of AMPA Receptor Subunit gria2? Transcript to Ensure Normal Development of Nervous System and Cranial Neural Crest Cells  

PubMed Central

Background Adar2 deaminates selective adenosines to inosines (A-to-I RNA editing) in the double-stranded region of nuclear transcripts. Although the functions of mouse Adar2 and its biologically most important substrate gria2, encoding the GluA2 subunit of AMPA (?-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptor, have been extensively studied, the substrates and functions of zebrafish Adar2 remain elusive. Methods/Principal Findings Expression of Adar2 was perturbed in the adar2 morphant (adar2MO), generated by antisense morpholio oligonucleotides. The Q/R editing of gria2? was reduced in the adar2MO and was enhanced by overexpression of Adar2, demonstrating an evolutionarily conserved activity between zebrafish and mammalian Adar2 in editing the Q/R site of gria2. To delineate the role of Q/R editing of gria2? in the developmental defects observed in the adar2MO, the Q/R editing of gria2? was specifically perturbed in the gria2?QRMO, generated by a morpholio oligonucleotide complementary to the exon complementary sequence (ECS) required for the Q/R editing. Analogous to the adar2-deficient and Q/R-editing deficient mice displaying identical neurological defects, the gria2?QRMO and adar2MO displayed identical developmental defects in the nervous system and cranial cartilages. Knockdown p53 abolished apoptosis and partially suppressed the loss of spinal cord motor neurons in these morphants. However, reducing p53 activity neither replenished the brain neuronal populations nor rescued the developmental defects. The expressions of crestin and sox9b in the neural crest cells were reduced in the adar2MO and gria2?QRMO. Overexpressing the edited GluA2?R in the adar2MO restored normal expressions of cresting and sox9b. Moreover, overexpressing the unedited GluA2?Q in the wild type embryos resulted in reduction of crestin and sox9b expressions. These results argue that an elevated GluA2?Q level is sufficient for generating the cranial neural crest defects observed in the adar2MO. Our results present a link between dysfunction of AMPA receptors and defective development of the nervous system and cranial neural crest in the zebrafish.

Physiological Environment Induces Quick Response - Slow Exhaustion Reactions  

PubMed Central

In vivo environments are highly crowded and inhomogeneous, which may affect reaction processes in cells. In this study we examined the effects of intracellular crowding and an inhomogeneity on the behavior of in vivo reactions by calculating the spectral dimension (ds), which can be translated into the reaction rate function. We compared estimates of anomaly parameters obtained from fluorescence correlation spectroscopy (FCS) data with fractal dimensions derived from transmission electron microscopy (TEM) image analysis. FCS analysis indicated that the anomalous property was linked to physiological structure. Subsequent TEM analysis provided an in vivo illustration; soluble molecules likely percolate between intracellular clusters, which are constructed in a self-organizing manner. We estimated a cytoplasmic spectral dimension ds to be 1.39?±?0.084. This result suggests that in vivo reactions initially run faster than the same reactions in a homogeneous space; this conclusion is consistent with the anomalous character indicated by FCS analysis. We further showed that these results were compatible with our Monte-Carlo simulation in which the anomalous behavior of mobile molecules correlates with the intracellular environment, leading to description as a percolation cluster, as demonstrated using TEM analysis. We confirmed by the simulation that the above-mentioned in vivo like properties are different from those of homogeneously concentrated environments. Additionally, simulation results indicated that crowding level of an environment might affect diffusion rate of reactant. Such knowledge of the spatial information enables us to construct realistic models for in vivo diffusion and reaction systems.

Momentum kill procedure can quickly control blowouts  

SciTech Connect

The momentum kill method can help in quickly regaining control of a blowing well, providing the blowing well rate and fluid properties can be estimated reasonably. The momentum of the kill fluid counteracts and overcomes the flowing momentum of formation fluids. In other words, sufficient mud density pumped at a sufficient rate is directed into the flow stream to force the escaping fluid column back into the well bore. Sufficient kill fluid hydrostatic pressure must be stacked'' in the hole so that the well remains dead after the operation. The momentum kill is not a panacea for all blowouts. An assessment must be made of the potential problems unique to this method, and certain requirements must be met if the technique is to be successful. The paper discusses some of the considerations for evaluating the use of the momentum kill method.

Quick and Accurate Monitoring Via Metaphor Graphics  

PubMed Central

The present study addresses the use of one class of representation, metaphor graphics, as an aid to monitoring a rapidly changing data intensive situation, in this case a patient on a mechanical ventilator. Eight experts in the field of mechanical ventilation viewed summaries containing seven days of data related to a single patient and, as quickly as possible, decided whether the patient was steadily improving, steadily worsening, or was initially moving in one of these two directions but then reversed course. Accuracy was extremely high for both graphic and numerical versions of the summaries but graphic representation led to performance that was significantly faster, averaging half the time required for numeric representation. These findings complement and extend previous research showing that metaphoric graphic representation leads to Bayesian diagnostic reasoning that is extremely accurate but much faster than reasoning via numerical tables.

The low-NO(x) emitting potential of rich-burn/quick-mix/lean-burn )RQL) combustion makes it an attractive option for engines of future stratospheric aircraft. Because NO(x) formation is exponentially dependent on temperature, the success of the RQL combustor depends on minimizing high temperature stoichiometric pocket formation in the quick-mixing section. An experiment was designed and built, and tests were performed to characterize reaction and mixing properties of jets issuing from round orifices into a hot, fuel-rich crossflow confined in a cylindrical duct. The reactor operates on propane and presents a uniform, non-swirling mixture to the mixing modules. Modules consisting of round orifice configurations of 8, 9, 10, 12, 14, and 18 holes were evaluated at a momentum-flux ratio of 57 and jet-to-mainstream mass-flaw ratio of 2.5. Temperatures and concentrations of O2, CO2, CO, HC, and NO(x) were obtained upstream, down-stream, and within the orifice plane to determine jet penetration as well as reaction processes. Jet penetration was a function of the number of orifices and affected the mixing in the reacting system. Of the six configurations tested, the 14-hole module produced jet penetration close to the module half-radius and yielded the best mixing and most complete combustion at a plane one duct diameter from the orifice leading edge. The results reveal that substantial reaction and heat release occur in the jet mixing zone when the entering effluent is hot and rich, and that the experiment as designed will serve to explore satisfactorily jet mixing behavior under realistic reacting conditions in future studies.

Quick management of accidental tritium exposure cases.  

PubMed

Removal half-life (RHL) of tritium is one of the best means for optimising medical treatment, reduction of committed effective dose (CED) and quick/easy handling of a large group of workers for medical treatment reference. The removal of tritium from the body depends on age, temperature, relative humidity and daily rainfall; so tritium removal rate, its follow-up and proper data analysis and recording are the best techniques for management of accidental acute tritium exposed cases. The decision of referring for medical treatment or medical intervention (MI) would be based on workers' tritium RHL history taken from their bodies at the facilities. The workers with tritium intake up to 1 ALI shall not be considered for medical treatment as it is a derived limit of annual total effective dose. The short-term MI may be considered for tritium intake of 1-10 ALI; however, if the results show intake ?100 ALI, extended strong medical/therapeutic intervention may be recommended based on the severity of exposure for maximum CED reduction requirements and annual total effective dose limit. The methodology is very useful for pressurized heavy water reactors (PHWRs) which are mainly operated by Canada and India and future fusion reactor technologies. Proper management will optimise the cases for medical treatment and enhance public acceptance of nuclear fission and fusion reactor technologies. PMID:22349318

Airborne sensor integration for quick reaction programs  

NASA Astrophysics Data System (ADS)

In this paper we present an approach to integrate sensors to meet the demanding requirements of Quick Reaction Capability (QRC) airborne programs. Traditional airborne sensors are generally highly integrated and incorporate custom sensor technologies and interfaces. Custom solutions and new technologies often require significant engineering to achieve a high technology readiness level (TRL) and to meet the overall mission objective. Our approach differs from traditional approaches in that we strive to achieve an integrated solution through regular review, assessment, and identification of relevant industry "best athlete" technologies. Attention is focused on solution providers that adhere to standard interfaces and formats, incorporate non-proprietary techniques, are deemed highly-reliable/repeatable, and enable assembly production. Processes and engineering tools/methods have traditionally been applied to dozens of longer-acquisition space-based ISR programs over 50 years. We have recently leveraged these techniques to solve airborne Intelligence, Surveillance and Reconnaissance (ISR) mission challenges. This presentation describes and illustrates key aspects and examples of these techniques, solving real-world airborne mission needs.

Seven lean years. [No quick fix available  

SciTech Connect

The end of the cheap oil era is having a more profound impact than any other single issue or event since World War II, making the everything crisis a more-appropriate label than energy crisis. Warnings from OPEC that oil may rise to $60 per barrel will not have worldwide inventories as a moderating force because the Iran-Iraq war has reduced OPEC production to the point where oil companies are unwilling to draw down their stockpiles. The cartel's prices have merely exploited a worldwide increase in demand for oil that would have pushed prices up anyway. The social and economic havoc is straining the economies of developed countries and could bankrupt and destabilize much of the Third World. The search for non-OPEC oil sources and alternatives to oil prompted a global race to discover new reserves, exploit renewable fuel sources, and initiate conservation. With no quick fix available, a painful period is foreseen while people learn to husband natural resources. (DCK)

Laboratory Selection Quickly Erases Historical Differentiation  

PubMed Central

The roles of history, chance and selection have long been debated in evolutionary biology. Though uniform selection is expected to lead to convergent evolution between populations, contrasting histories and chance events might prevent them from attaining the same adaptive state, rendering evolution somewhat unpredictable. The predictability of evolution has been supported by several studies documenting repeatable adaptive radiations and convergence in both nature and laboratory. However, other studies suggest divergence among populations adapting to the same environment. Despite the relevance of this issue, empirical data is lacking for real-time adaptation of sexual populations with deeply divergent histories and ample standing genetic variation across fitness-related traits. Here we analyse the real-time evolutionary dynamics of Drosophila subobscura populations, previously differentiated along the European cline, when colonizing a new common environment. By analysing several life-history, physiological and morphological traits, we show that populations quickly converge to the same adaptive state through different evolutionary paths. In contrast with other studies, all analysed traits fully converged regardless of their association with fitness. Selection was able to erase the signature of history in highly differentiated populations after just a short number of generations, leading to consistent patterns of convergent evolution.

Climate Data Operators for quick look visualization  

NASA Astrophysics Data System (ADS)

Geophysical computations, in particular numerical weather and climate predictions, consume huge computational resources and generate voluminous amount of multidimensional data in various formats. The post-processing of these data involves, manipulation to generate diagnostics and visualization. These tasks demand software tools, that are efficient in data handling, computation and graphical processing. Apart from that, these tools need to be highly user friendly characterized by a smooth learning curve, as they address a wider audience with varying backgrounds. A typical work flow to accomplish the task in e.g. climate prediction, involves the usage of various interactive and non-interactive tools in tandem. One such work flow can be constituted by using the Climate Data Operators (CDO) software that enables the efficient manipulation of the data, in conjunction with other visualization tools. CDO provides over 600 command line operators for performing simple statistical and arithmetic functions, selection and sub-sampling and spatial interpolation of the data. But the ever increasing work flow requirements necessitates, a seamless synergy of data manipulation and visualization tools. Such a synergy improves the work flow efficiency and enhances the productivity. In this direction, new plotting operators are created in the CDO by exploiting the plotting capabilities of the Magics++ library. These plotting operators are in tune with the chaining capabilities of the existing CDO operators and provide a non-interactive quick look visualization of the data in the form of contour, vector, shaded and graphical plots during post-processing. Moreover, here we apply these operators to monitor online, large ensemble climate prediction computations and avoid unnecessary wastage of valuable computational resources, especially during the model development and tuning phase.

Q/R site interactions with the M3 helix in GluK2 kainate receptor channels revealed by thermodynamic mutant cycles  

PubMed Central

RNA editing at the Q/R site near the apex of the pore loop of AMPA and kainate receptors controls a diverse array of channel properties, including ion selectivity and unitary conductance and susceptibility to inhibition by polyamines and cis-unsaturated fatty acids, as well as subunit assembly into tetramers and regulation by auxiliary subunits. How these different aspects of channel function are all determined by a single amino acid substitution remains poorly understood; however, several lines of evidence suggest that interaction between the pore helix (M2) and adjacent segments of the transmembrane inner (M3) and outer (M1) helices may be involved. In the present study, we have used double mutant cycle analysis to test for energetic coupling between the Q/R site residue and amino acid side chains along the M3 helix. Our results demonstrate interaction with several M3 locations and particularly strong coupling to substitution for L614 at the level of the central cavity. In this location, replacement with smaller side chains completely and selectively reverses the effect of fatty acids on gating of edited channels, converting strong inhibition of wild-type GluK2(R) to nearly 10-fold potentiation of GluK2(R) L614A.

Interaction of hirudin with the dysthrombins Quick I and II.  

PubMed

The interaction of hirudin with the dysfunctional enzymes thrombin Quick I and II has been investigated. Natural and recombinant hirudin caused nonlinear competitive inhibition of thrombin Quick I. The results were consistent with thrombin Quick I existing in two forms that have different affinities for hirudin. The affinities of these forms for natural hirudin were respectively 10(4)- and 10(6)-fold lower than that of alpha-thrombin. In contrast, truncated hirudin molecules lacking the C-terminal tail of the molecule caused linear inhibition of thrombin Quick I. These results indicate that different modes of interaction of the two forms of thrombin Quick I with the C-terminal tail of hirudin were the cause of the nonlinear inhibition. Comparison of the dissociation constants of thrombin Quick I with the truncated and full-length forms of hirudin suggested that the interactions that normally occur between the C-terminal tail of hirudin and thrombin were completely disrupted with the low-affinity form of thrombin Quick I. Thrombin Quick II displayed an affinity for natural hirudin that was 10(3)-fold lower than that observed with alpha-thrombin. In contrast, it bound a mutant hirudin with altered N-terminal amino acids only 16-fold less tightly. These results are discussed in terms of structural alterations in the active-site cleft in thrombin Quick II. PMID:2054344

Production and characterization of a murine monoclonal IgM antibody to human C1q receptor (C1qR)  

SciTech Connect

A hybridoma cell line that produces a monoclonal antibody (MAb) to cell surface C1q receptor (C1qr) has been produced by fusion of the P3 x 63-Ag8.653 mouse myeloma cell line with the spleen cells of a CD-1 mouse that had been hyperimmunized with viable Raji cell suspensions (5 x 10/sup 7/ cells/inoculum). This MAb, designated II1/D1, is an IgM antibody with lambda-light chain specificity. Radiolabeled or unlabeled, highly purified II1/D1 was used to determine that: a) this antibody competes for C1q binding sites on C1qR-bearing cells; b) the molecule recognized by this MAb is the C1qR; and c) cells that are known to bind C1q also bind II1/D1 in a specific manner. Western blot analysis of solubilized Raji, or U937 cell membranes, showed that the /sup 125/I-MAb detected a major protein band of approximately 85000 m.w. in its unreduced state, indicating that the C1qR is similar, if not identical, in both types of cells. Analyses of /sup 125/I-II/D1 binding experiments revealed that the antibody bound to Raji cells or u937 cells in a specific manner. Uptake of the antibody was saturable, with equilibrium virtually attained within 35 min. Scatchard analysis of the binding data using the intact MAb suggests that the affinity constant K/sub D/ is 2.9 x 10/sup -10/ M, and at apparent saturation, 24.6 ng of the antibody were bound per 2 x 10/sup 6/ cells, giving an estimated 7.8 x 10/sup 3/ antibody molecules bound per cell. That the II1/D1 antibody is specifically directed to the C1q was further evidenced by an ELISA in which the ability of C1qR-bearing cells to bind the MAb was abrogated by c-C1q in a specific dose-dependent manner.

JACIE Radiometric Assessment of QuickBird Multispectral Imagery  

NASA Technical Reports Server (NTRS)

Radiometric calibration of commercial imaging satellite products is required to ensure that science and application communities can place confidence in the imagery they use and can fully understand its properties. Inaccurate radiometric calibrations can lead to erroneous decisions and invalid conclusions and can limit intercomparisons with other systems. To address this calibration need, the NASA Stennis Space Center (SSC) Earth Science Applications (ESA) directorate,through the Joint Agency for Commercial Imagery Evaluation (JACIE) framework, established a commercial imaging satellite radiometric calibration team consisting of two groups: 1) NASA SSC ESA, supported by South Dakota State University, and 2) the University of Arizona Remote Sensing Group. The two groups determined the absolute radiometric calibration coefficients of the Digital Globe 4-band, 2.4-m QuickBird multispectral product covering the visible through near-infrared spectral region. For a 2-year period beginning in 2002, both groups employed some variant of a reflectance-based vicarious calibration approach, which required ground-based measurements coincident with QuickBird image acquisitions and radiative transfer calculations. The groups chose several study sites throughout the United States that covered nearly the entire dynamic range of the QuickBird sensor. QuickBird at-sensor radiance values were compared with those estimated by the two independent groups to determine the QuickBird sensor's radiometric accuracy. Approximately 20 at-sensor radiance estimates were vicariously determined each year. The estimates were combined to provide a high-precision radiometric gain calibration coefficient. The results of this evaluation provide the user community with an independent assessment of the QuickBird sensor's absolute calibration and stability over the 2-year period. While the techniques and method described reflect those developed at the NASA SSC, the results of both JACIE team groups are included in this paper.

Intentions of older homebound women with regard to reaching help quickly.  

PubMed

The purposes of this longitudinal phenomenological study were to describe intentions of older women relative to reaching help quickly (RHQ), to place those intentions in personal-social context, and to compare intentions of subscribers to a personal emergency response system (PERS) and nonsubscribers. The 40 participants were aged 85 or older, resided alone, and needed help to leave home. Two contextual features ("recognizing my risk of being unable to RHQ" and "recognizing my need for a RHQ device to sustain myself") were basic to two phenomena ("negotiating reliance on people to reach quickly if I need help" and "reducing my risk of being unable to RHQ"). There was greater variation in intentions and context within each of the two naturally occurring groups (subscribers and nonsubscribers) than between them. Practitioners cannot assume that women intend to use available RHQ devices in specific situations; preventive nursing involves proactive exploration of intentions relative to RHQ. PMID:22146885

Quick phases control ocular torsion during smooth pursuit.  

PubMed

One of the open questions in oculomotor control of visually guided eye movements is whether it is possible to smoothly track a target along a curvilinear path across the visual field without changing the torsional stance of the eye. We show in an experimental study of three-dimensional eye movements in subhuman primates (Macaca mulatta) that although the pursuit system is able to smoothly change the orbital orientation of the eye's rotation axis, the smooth ocular motion was interrupted every few hundred milliseconds by a small quick phase with amplitude <1.5° while the animal tracked a target along a circle or ellipse. Specifically, during circular pursuit of targets moving at different angular eccentricities (5°, 10°, and 15°) relative to straight ahead at spatial frequencies of 0.067 and 0.1 Hz, the torsional amplitude of the intervening quick phases was typically around 1° or smaller and changed direction for clockwise vs. counterclockwise tracking. Reverse computations of the eye rotation based on the recorded angular eye velocity showed that the quick phases facilitate the overall control of ocular orientation in the roll plane, thereby minimizing torsional disturbances of the visual field. On the basis of a detailed kinematic analysis, we suggest that quick phases during curvilinear smooth tracking serve to minimize deviations from Donders' law, which are inevitable due to the spherical configuration space of smooth eye movements.

Covert Anti-Compensatory Quick Eye Movements during Head Impulses  

PubMed Central

Background Catch-up saccades during passive head movements, which compensate for a deficient vestibulo-ocular reflex (VOR), are a well-known phenomenon. These quick eye movements are directed toward the target in the opposite direction of the head movement. Recently, quick eye movements in the direction of the head movement (covert anti-compensatory quick eye movements, CAQEM) were observed in older individuals. Here, we characterize these quick eye movements, their pathophysiology, and clinical relevance during head impulse testing (HIT). Methods Video head impulse test data from 266 patients of a tertiary vertigo center were retrospectively analyzed. Forty-three of these patients had been diagnosed with vestibular migraine, and 35 with Menière’s disease. Results CAQEM occurred in 38% of the patients. The mean CAQEM occurrence rate (per HIT trial) was 11±10% (mean±SD). Latency was 83±30 ms. CAQEM followed the saccade main sequence characteristics and were compensated by catch-up saccades in the opposite direction. Compensatory saccades did not lead to more false pathological clinical head impulse test assessments (specificity with CAQEM: 87%, and without: 85%). CAQEM on one side were associated with a lower VOR gain on the contralateral side (p<0.004) and helped distinguish Menière’s disease from vestibular migraine (p?=?0.01). Conclusion CAQEM are a common phenomenon, most likely caused by a saccadic/quick phase mechanism due to gain asymmetries. They could help differentiate two of the most common causes of recurrent vertigo: vestibular migraine and Menière’s disease.

QUICK - AN INTERACTIVE SOFTWARE ENVIRONMENT FOR ENGINEERING DESIGN  

NASA Technical Reports Server (NTRS)

QUICK provides the computer user with the facilities of a sophisticated desk calculator which can perform scalar, vector and matrix arithmetic, propagate conic orbits, determine planetary and satellite coordinates and perform other related astrodynamic calculations within a Fortran-like environment. QUICK is an interpreter, therefore eliminating the need to use a compiler or a linker to run QUICK code. QUICK capabilities include options for automated printing of results, the ability to submit operating system commands on some systems, and access to a plotting package (MASL)and a text editor without leaving QUICK. Mathematical and programming features of QUICK include the ability to handle arbitrary algebraic expressions, the capability to define user functions in terms of other functions, built-in constants such as pi, direct access to useful COMMON areas, matrix capabilities, extensive use of double precision calculations, and the ability to automatically load user functions from a standard library. The MASL (The Multi-mission Analysis Software Library) plotting package, included in the QUICK package, is a set of FORTRAN 77 compatible subroutines designed to facilitate the plotting of engineering data by allowing programmers to write plotting device independent applications. Its universality lies in the number of plotting devices it puts at the user's disposal. The MASL package of routines has proved very useful and easy to work with, yielding good plots for most new users on the first or second try. The functions provided include routines for creating histograms, "wire mesh" surface plots and contour plots as well as normal graphs with a large variety of axis types. The library has routines for plotting on cartesian, polar, log, mercator, cyclic, calendar, and stereographic axes, and for performing automatic or explicit scaling. The lengths of the axes of a plot are completely under the control of the program using the library. Programs written to use the MASL subroutines can be made to output to the Calcomp 1055 plotter, the Hewlett-Packard 2648 graphics terminal, the HP 7221, 7475 and 7550 pen plotters, the Tektronix 40xx and 41xx series graphics terminals, the DEC VT125/VT240 graphics terminals, the QMS 800 laser printer, the Sun Microsystems monochrome display, the Ridge Computers monochrome display, the IBM/PC color display, or a "dumb" terminal or printer. Programs using this library can be written so that they always use the same type of plotter or they can allow the choice of plotter type to be deferred until after program execution. QUICK is written in RATFOR for use on Sun4 series computers running SunOS. No source code is provided. The standard distribution medium for this program is a .25 inch streaming magnetic tape cartridge in UNIX tar format. An electronic copy of the documentation in ASCII format is included on the distribution medium. QUICK was developed in 1991 and is a copyrighted work with all copyright vested in NASA.

Quick application/release nut with engagement indicator  

NASA Technical Reports Server (NTRS)

A composite nut is shown which permits a fastener to be inserted or removed from either side with an indicator of fastener engagement. The nut has a plurality of segments, preferably at least three segments, which are internally threaded, spring loaded apart by an internal spring, and has detents on opposite sides which force the nut segments into operative engagements with a threaded member when pushed in and release the segments for quick insertion or removal of the nut when moved out. When the nut is installed, end pressure on one of the detents presses the nut segments into operative engagement with a threaded member where continued rotation locks the structure together with the detents depressed to indicate positive locking engagement of the nut. On removal, counterclockwise rotation of the nut relieves the endwise pressure on the detents, permitting internal springs to force the detents outward and allowing the nut segments to move outward and separate to permit quick removal of the fastener.

[Importance of Quick, partial thromboplastin time, and Co].  

PubMed

The Quick test and activated partial thromboplastin time (aPTT) are so-called global assays used to characterize different steps in plasmatic hemostasis. They reflect hemostasis in its classical differentiation into extrinsic and intrinsic pathways. However, they do not cover physiological aspects of cell-based hemostasis. Results are not necessarily congruent with a specific clinical situation and do not replace a complete medical history. Patients suffering from hemophilia A or B, for example, have normal Quick test results. Severe factor XII deficiency reveals an extreme aPTT prolongation without a significant bleeding tendency. In Lupus patients, aPTT is also prolonged with clinically a rather increased thrombotic risk. Fibrinogen as a substrate of coagulation discloses pathological results in both global tests in case of considerable reduction. In case of positive bleeding history and a normal global assay, disorders in platelets, von Willebrand factor and factor XIII must be considered. Reduced Quick test results may be expected in factor VII, II, V, or X deficiency. Disorders of liver synthesis of coagulation factors as well as vitamin K deficiency will be indicated by the Quick test rather than by aPTT. The most frequent hereditary reasons for a prolonged aPTT are hemophilia A and B as well as von Willebrand disease. In case of an acquired bleeding tendency, the diagnostic strategy must include autoantibodies. The sensitivity of the aPTT reagent varies widely. Low-molecular weight heparin and pentasaccharides do not influence the test. Oral direct inhibitors may reveal pathological results in a reagent-dependent manner. PMID:24781934

Straight talk with...Jonathan Quick. Interview by Roxanne Khamsi.  

PubMed

In April 2012, an e-mail announcing the impending closure of the Global Health Council following the cancellation of its annual conference sent shockwaves through its community of 325 organizational members spanning 39 countries. For 40 years, the Alexandria, Virginia-based nonprofit had acted as an umbrella organization for stakeholders that include some of the world's most prominent medical institutions and drug companies. As the June 2012 closure of the GHC approached, several members stepped in to rescue the operation, including Jonathan Quick, a family physician and CEO of Management Sciences for Health, a Cambridge, Massachusetts-based outfit that works to strengthen health systems and infrastructure around the globe. In January, a new GHC board was elected, with Quick at the helm. In the ensuing months the board members have built the organization back up-albeit as a leaner and more targeted operation. This past summer, they launched a revamped website (www.globalhealth.org) and are looking ahead to convening GHC members at the UN General Assembly on 18 September in New York, where the discussion of Millennium Development Goals will take place. As Nature Medicine went to press, the relaunched GHC was in the midst of recruiting for its first staff position, executive director. Roxanne Khamsi spoke with Quick about the health of the organization. PMID:24013739

Data compression for data archival, browse or quick-look  

NASA Technical Reports Server (NTRS)

Soon after space and Earth science data is collected, it is stored in one or more archival facilities for later retrieval and analysis. Since the purpose of the archival process is to keep an accurate and complete record of data, any data compression used in an archival system must be lossless, and protect against propagation of error in the storage media. A browse capability for space and Earth science data is needed to enable scientists to check the appropriateness and quality of particular data sets before obtaining the full data set(s) for detailed analysis. Browse data produced for these purposes could be used to facilitate the retrieval of data from an archival facility. Quick-look data is data obtained directly from the sensor for either previewing the data or for an application that requires very timely analysis of the space or Earth science data. Two main differences between data compression techniques appropriate to browse and quick-look cases, are that quick-look can be more specifically tailored, and it must be limited in complexity by the relatively limited computational power available on space platforms.

Quick-disconnect harness system for helmet-mounted displays  

NASA Astrophysics Data System (ADS)

We have designed a pilot's harness-mounted, high voltage quick-disconnect connectors with 62 pins, to transmit voltages up to 13.5 kV and video signals with 70 MHz bandwidth, for a binocular helmet-mounted display system. It connects and disconnects with power off, and disconnects 'hot' without pilot intervention and without producing external sparks or exposing hot embers to the explosive cockpit environment. We have implemented a procedure in which the high voltage pins disconnect inside a hermetically-sealed unit before the physical separation of the connector. The 'hot' separation triggers a crowbar circuit in the high voltage power supplies for additional protection. Conductor locations and shields are designed to reduce capacitance in the circuit and avoid crosstalk among adjacent circuits. The quick- disconnect connector and wiring harness are human-engineered to ensure pilot safety and mobility. The connector backshell is equipped with two hybrid video amplifiers to improve the clarity of the video signals. Shielded wires and coaxial cables are molded as a multi-layered ribbon for maximum flexibility between the pilot's harness and helmet. Stiff cabling is provided between the quick-disconnect connector and the aircraft console to control behavior during seat ejection. The components of the system have been successfully tested for safety, performance, ergonomic considerations, and reliability.

Reliability and Frequency Response of Excitatory Signals Transmitted to Different Types of Retinal Ganglion Cell  

PubMed Central

The same visual stimulus evokes a different pattern of neural signals each time the stimulus is presented. Because this unreliability reduces visual performance, it is important to understand how it arises from neural circuitry. We asked whether different types of ganglion cell receive excitatory signals with different reliability and frequency content and, if so, how retinal circuitry contributes to these differences. If transmitter release is governed by Poisson statistics, the SNR of the postsynaptic currents (ratio of signal power to noise power) should grow linearly with quantal rate (qr), a prediction that we confirmed experimentally. Yet ganglion cells of the same type receive quanta at different rates. Thus to obtain a measure of reliability independent of quantal rate, we calculated the ratio SNR/qr, and found this measure to be type-specific. We also found type-specific differences in the frequency content of postsynaptic currents, although types whose dendrites branched at nearby levels of the inner plexiform layer (IPL) had similar frequency content. As a result, there was an orderly distribution of frequency response through the depth of the IPL, with alternating layers of broadband and high-pass signals. Different types of bipolar cell end at different depths of the IPL and provide excitatory synapses to ganglion cell dendrites there. Thus these findings indicate that a bipolar cell synapse conveys signals whose temporal message and reliability (SNR/qr) are determined by neuronal type. The final SNR of postsynaptic currents is set by the dendritic membrane area of a ganglion cell, which sets the numbers of bipolar cell synapses and thus the rate at which it receives quanta [SNR = qr × (SNR/qr)].

Adaptive Selection of Surviving Symbol Replica Candidates for Quasi-Maximum Likelihood Detection Using M-Algorithm with QR-Decomposition for OFDM MIMO Multiplexing  

NASA Astrophysics Data System (ADS)

This paper proposes an adaptive selection algorithm for the surviving symbol replica candidates (ASESS) based on the maximum reliability in maximum likelihood detection with QR decomposition and the M-algorithm (QRM-MLD) for Orthogonal Frequency Division Multiplexing (OFDM) multiple-input multiple-output (MIMO) multiplexing. In the proposed algorithm, symbol replica candidates newly-added at each stage are ranked for each surviving symbol replica from the previous stage using multiple quadrant detection. Then, branch metrics are calculated only for the minimum number of symbol replica candidates with a high level of reliability using an iterative loop based on symbol ranking results. Computer simulation results show that the computational complexity of the QRM-MLD employing the proposed ASESS algorithm is reduced to approximately 1/4 and 1/1200 compared to that of the original QRM-MLD and that of the conventional MLD with squared Euclidian distance calculations for all symbol replica candidates, respectively, assuming the identical achievable average packet error rate (PER) performance in 4-by-4 MIMO multiplexing with 16QAM data modulation. The results also show that 1-Gbps throughput is achieved at the average received signal energy per bit-to-noise power spectrum density ratio (Eb/N0) per receiver antenna of approximately 9dB using the ASESS algorithm in QRM-MLD associated with 16QAM modulation and Turbo coding with the coding rate of 8/9 assuming a 100-MHz bandwidth for a 12-path Rayleigh fading channel (root mean square (r.m.s.) delay spread of 0.26µs and maximum Doppler frequency of 20Hz).

Increased Hyaluronan Levels in HABP1/p32/gC1qR Overexpressing HepG2 Cells Inhibit Autophagic Vacuolation Regulating Tumor Potency  

PubMed Central

Tumor growth and development is influenced by its microenvironment. A major extracellular matrix molecule involved in cancer progression is hyaluronan (HA). Hyaluronan and expression of a number of hyaladherin family proteins are dramatically increased in many cancer malignancies. One such hyaladherin, hyaluronan-binding protein 1 (HABP1/p32/gC1qR) has been considered to be a biomarker for tumor progression. Interestingly, overexpression of HABP1 in fibroblast has been shown to increase autophagy via generation of excess reactive oxygen species (ROS) and depletion of HA leading to apoptosis. Cancerous cells are often found to exhibit decreased rate of proteolysis/autophagy in comparison to their normal counterparts. To determine if HABP1 levels alter tumorigenicity of cancerous cells, HepR21, the stable transfectant overexpressing HABP1 in HepG2 cell line was derived. HepR21 has been shown to have increased proliferation rate than HepG2, intracellular HA cable formation and enhanced tumor potency without any significant alteration of intracellular ROS. In this paper we have observed that HepR21 cells containing higher endogenous HA levels, have downregulated expression of the autophagic marker, MAP-LC3, consistent with unaltered levels of endogenous ROS. In fact, HepR21 cells seem to have significant resistance to exogenous ROS stimuli and glutathione depletion. HepR21 cells were also found to be more resilient to nutrient starvation in comparison to its parent cell line. Decline in intracellular HA levels and HA cables in HepR21 cells upon treatment with HAS inhibitor (4-MU), induced a surge in ROS levels leading to increased expression of MAP-LC3 and tumor suppressors Beclin 1 and PTEN. This suggests the importance of HABP1 induced HA cable formation in enhancing tumor potency by maintaining the oxidant levels and subsequent autophagic vacuolation.

Evaluation of NeQuick 2 derived vertical TEC at three northern mid-latitude locations  

NASA Astrophysics Data System (ADS)

NeQuick 2 is the latest version of the three-dimensional and time dependent ionospheric electron density model developed at the T/ICT4D (former ARPL) of the Abdus Salam International Centre for Theoretical Physics (ICTP) - Trieste, Italy and at the Institute for Geophysics, Astrophysics and Meteorology of the University of Graz, Austria. The purpose of this work is to identify possible limitations of the model. Therefore, the ability of NeQuick 2 in reproducing the vertical Total Electron Content (vTEC) derived from GPS observations using different input sources has been evaluated. The daily solar flux in 10.7 cm, the monthly smoothed solar flux and the hourly daily ionosonde derived F2 peak parameters, foF2 and hmF2, have been therefore used as model drivers to compute the vTEC at the relevant locations. Peak parameter values from three ionosonde stations (Ebre, El Arenosillo and Ramey) and GPS-derived vTEC data obtained from the corresponding co-located receivers (ebre, sfer, pur3) have been processed for the present work. The available data for the years 2000 and 2004, corresponding to high and moderate solar activity periods, have been considered to be able to estimate the model performance in a wide range of geophysical conditions. For each location, the data analysis has been based on statistical comparisons between experimental and retrieved vTEC. The results indicate that the differences between NeQuick 2-computed and GPS-derived vTEC exhibit well defined diurnal and seasonal patterns that depend on the location and period considered. On average, NeQuick 2 underestimates the vTEC during nighttime, mainly in the winter months and slightly during the summer months. In the daytime hours on the European locations, the model generally overestimates the vTEC in winter months, having an opposite behavior in the summer months. At PRJ18/pur3 location the NeQuick 2 response is more complex. During high solar activity, the daily difference between modeled and GPS derived TEC mean behavior are similar to the observed on the European locations. During the mid-to-low solar activity period the model generally overestimates vTEC for all seasons. In addition, the post-sunset enhancements of the TEC values are usually overestimated by the model. For all locations and solar activity conditions evaluated, the local sunrise hours and the equinoctial months are usually the best reproduced periods.

The Psychologist Said Quickly, "Dialogue Descriptions Modulate Reading Speed!"  

PubMed Central

The current study investigates whether the semantic content of a dialogue description can affect reading times on an embedded quote to determine if the speed at which a character is described as saying a quote influences how quickly it is read. Yao and Scheepers (2011) previously found that readers were faster to read direct quotes when the preceding context implied that the talker generally spoke quickly, an effect attributed to perceptual simulation of talker speed. The current study manipulated the speed of a physical action performed by the speaker independently from character talking rate to determine if these sources have separable effects on perceptual simulation of a direct quote. Results showed that readers spent less time reading direct quotes described as being said quickly compared to slowly (e.g., John walked/bolted into the room and said energetically/nonchalantly, “I finally found my car keys”), an effect that was not present when a nearly identical phrase was presented as an indirect quote (e.g., John…said energetically that he finally found his car keys). The speed of the character’s movement did not affect direct quote reading times. Furthermore, fast adverbs were themselves read significantly faster than slow adverbs, an effect we attribute to implicit effects on the eye movement program stemming from automatically activated semantic features of the adverbs. Our findings add to the literature on perceptual simulation by showing that these effects can be instantiated with only a single adverb, and are strong enough to override effects of global sentence speed.

This engineering note documents calculations done to determine the margin of safety for the lower clean room roof. The analysis was done to give me a feeling of what the loads, stresses and capacity of the roof is prior to installation and installation work to be done for the helium refrigerator upgrade. The result of this quick look showed that the calculated loads produce stress values and loads at about half the allowables. Based on this result, I do not think that special precautions above personal judgement are required for the installation work.

Improved Quick Disconnect (QD) Interface Through Fail Safe Parts Identification  

NASA Technical Reports Server (NTRS)

An extensive review of existing Quick Disconnects (QDs) mating and demating operations was performed to determine which shuttle part interface identifications and procedures contribute to human factor errors. The research methods used consisted of interviews with engineers and technicians, examination of incident reports, critiques of video and audio tapes of QD operations, and attendance of a Hyper QD operational course. The data strongly suggests that there are inherit human factor errors involved in QD operations. To promote fail-safe operations, QD interface problem areas and recommendations were outlined and reviewed. It is suggested that dialogue, investigations and recommendations continue.

International Space Station Increment-2 Quick Look Report  

NASA Technical Reports Server (NTRS)

The objective of this quick look report is to disseminate the International Space Station (ISS) Increment-2 reduced gravity environment preliminary analysis in a timely manner to the microgravity scientific community. This report is a quick look at the processed acceleration data collected by the Microgravity Acceleration Measurement System (MAMS) during the period of May 3 to June 8, 2001. The report is by no means an exhaustive examination of all the relevant activities, which occurred during the time span mentioned above for two reasons. First, the time span being considered in this report is rather short since the MAMS was not active throughout the time span being considered to allow a detailed characterization. Second, as the name of the report implied, it is a quick look at the acceleration data. Consequently, a more comprehensive report, the ISS Increment-2 report, will be published following the conclusion of the Increment-2 tour of duty. NASA sponsors the MAMS and the Space Acceleration Microgravity System (SAMS) to support microgravity science experiments, which require microgravity acceleration measurements. On April 19, 2001, both the MAMS and the SAMS units were launched on STS-100 from the Kennedy Space Center for installation on the ISS. The MAMS unit was flown to the station in support of science experiments requiring quasisteady acceleration data measurements, while the SAMS unit was flown to support experiments requiring vibratory acceleration data measurement. Both acceleration systems are also used in support of the vehicle microgravity requirements verification. The ISS reduced gravity environment analysis presented in this report uses mostly the MAMS acceleration data measurements (the Increment-2 report will cover both systems). The MAMS has two sensors. The MAMS Orbital Acceleration Research Experiment Sensor Subsystem, which is a low frequency range sensor (up to 1 Hz), is used to characterize the quasi-steady environment for payloads and vehicle. The MAMS High Resolution Acceleration Package is used to characterize the ISS vibratory environment up to 100 Hz. This quick look report presents some selected quasi-steady and vibratory activities recorded by the MAMS during the ongoing ISS Increment-2 tour of duty.

Multiprocessors used in life-critical real-time systems must recover quickly from failure. Part of this recovery consists of switching to a new task schedule which ensures that hard deadlines for critical tasks continue to be met. A dynamic programming algorithm is presented that ensures that backup, or contingency, schedules can be efficiently embedded within the original, 'primary' schedule to ensure that hard deadlines continue to be met in the face of up to a given maximum number of processor failures. Several illustrative examples are included.

Evaluation of quick tests for phosphorus determination in dairy manures.  

PubMed

Nutrients in animal manure are valuable inputs in agronomic crop production. Rapid and timely information about manure nutrient content are needed to minimize the risks of phosphorus (P) over-application and losses of dissolved P (DP) in runoff from fields treated with manure. We evaluated the suitability of a commercial hand-held reflectometer, a hydrometer, and an electrical conductivity (EC) meter for determining DP and total P (TP) in dairy manures. Bulk samples (n = 107) collected from farms across CT, MD, NY, PA, and VA were highly variable in total solids (TS) concentration, ranging from 11 to 213gL(-1), in suspensions' pH (6.3-9.2), and EC (6.2-53.3 dS m(-1)). Manure DP concentrations measured using the RQFlex reflectometer (RQFlex-DP(s)) were related to molybdate-reactive P (MRP(s)) concentrations as follows: RQFlex-DP(s) = 0.471 x MRP(s) + 1102 (r2 = 0.29). Inclusion of pH and squared-pH terms improved the prediction of manure DP from RQFlex results (r2 = 0.66). Excluding five outlier samples that had pH < or = 6.9 the coefficient of determination (r2) for the MRP(s) and RQFlex-DP(s) relationship was 0.83 for 95% of the samples. Manure TS were related to hydrometer specific gravity readings (r2 = 0.53) that were in turn related to TP (r2 = 0.34), but not to either RQFlex-DP or MRP. Relationships between suspensions' EC and DP or TP were non-significant. Therefore, the RQFlex method is the only viable option for on-site quick estimates of DP that can be made more robust when complemented with TS and pH measurements. The DP quick test can provide near real-time information on soluble manure nutrient content across a wide range of handling and storage conditions on dairy farms and quick estimates of potential soluble P losses in runoff following land applications of manure.

QuickBundles, a Method for Tractography Simplification  

PubMed Central

Diffusion MR data sets produce large numbers of streamlines which are hard to visualize, interact with, and interpret in a clinically acceptable time scale, despite numerous proposed approaches. As a solution we present a simple, compact, tailor-made clustering algorithm, QuickBundles (QB), that overcomes the complexity of these large data sets and provides informative clusters in seconds. Each QB cluster can be represented by a single centroid streamline; collectively these centroid streamlines can be taken as an effective representation of the tractography. We provide a number of tests to show how the QB reduction has good consistency and robustness. We show how the QB reduction can help in the search for similarities across several subjects.

International Space Station (ISS) Low Pressure Intramodule Quick Disconnect Failures  

NASA Technical Reports Server (NTRS)

A failure of an ISS intermodule Quick Disconnect (QD) during protoflight vibration testing of ISS regenerative Environmental Control and Life Support (ECLS) hardware led to the discovery of QD design, manufacturing, and test flaws which can yield the male QD susceptible to failure of the secondary housing seal and inadequate housing assembly locking mechanisms. Discovery of this failure had large implications when considering that currently there are 399 similar units on orbit and approximately 1100 units on the ground integrated into flight hardware. Discovery of the nature of the failure required testing and analysis and implementation of a recovery plan requiring part screening and review of element level and project hazard analysis to determine if secondary seals are required. Implementation also involves coordination with the Nodes and MPLM project offices, Regenerative ECLS Project, ISS Payloads, JAXA, ESA, and ISS Logistics and Maintenance.

Cardiopulmonary limited ultrasound examination for "quick-look" bedside application.  

PubMed

Although taking a "quick look" at the heart using a small ultrasound device is now feasible, a formal ultrasound imaging protocol to augment the bedside physical examination has not been developed. Therefore, we sought to evaluate the diagnostic accuracy and prognostic value of a cardiopulmonary limited ultrasound examination (CLUE) using 4 simplified diagnostic criteria that would screen for left ventricular dysfunction (LV), left atrial (LA) enlargement, inferior vena cava plethora (IVC+), and ultrasound lung comet-tail artifacts (ULC+) in patients referred for echocardiography. The CLUE was tested by interpretation of only the parasternal LV long-axis, subcostal IVC, and 2 lung apical views in each of 1,016 consecutive echocardiograms performed with apical lung imaging. For inpatients, univariate and multivariate logistic regression analyses were performed to assess the relations between mortality, CLUE findings, age, and gender. In this echocardiographic referral series, 78% (n = 792) were inpatient and 22% (n = 224) were outpatient. The CLUE criteria demonstrated a sensitivity, specificity, and accuracy for a LV ejection fraction of ?40% of 69%, 91%, and 89% and for LA enlargement of 75%, 72%, and 73%, respectively. CLUE findings of LV dysfunction, LA enlargement, IVC+, and ULC+ were seen in 16%, 53%, 34%, and 28% of inpatients. The best multivariate logistic model contained 3 predictors of in-hospital mortality: ULC+, IVC+ and male gender, with adjusted odds ratios (95% confidence intervals) of 3.5 (1.4 to 8.8), 5.8 (2.1 to 16.4), and 2.3 (0.9 to 5.8), respectively. In conclusion, a CLUE consisting of 4 quick-look "signs" has reasonable diagnostic accuracy for bedside use and contains prognostic information. PMID:21641569

The quick single-photon detector with many avalanche photo-diodes for quantum key distribution  

NASA Astrophysics Data System (ADS)

It is the closest technology to practice in the quantum communication at present to apply single-photon scheme to implement the quantum key distribution (QKD), and may achieve the absolute security in principle. Because of the limit of the response speed of the present single-photon detector, the code rate is still too low to come into practical use. The paper has put up a new idea to design a quick single-photon detector with a multi-port optic-fiber splitter or an optical switch array and many avalanche photo diodes (APD). All of the ports with APD work on time division and cooperate with the logic discrimination and deciding unit by the clock signal, thus the quick detection can come true to high repetition-rate pulses with a single photon. The multiple of the detection rate is decided by the number of the port. The optoelectronic integration can be adopted for the reliable detector. The applying of this detector will largely raise the code rate of the QKD, and stimulate the commercial use.

Psychometric Properties of the Quick Inventory of Depressive Symptomatology in Adolescents  

PubMed Central

Objective The clinician-rated (QIDS-C16) and self-report (QIDS-SR16) versions of the 16-item Quick Inventory of Depressive Symptomatology have been extensively examined in adult populations. This study evaluated both versions of the QIDS and the 17-item Children’s Depressive Rating Scale-Revised (CDRS-R) in an adolescent outpatient sample. Method Both the QIDS-C16 and QIDS-SR16 were completed for the adolescents. Three different methods were used to complete the QIDS-C16: (a) adolescents’ responses to clinician interviews; (b) parents’ responses to clinician interview; and (c) a composite score using the most pathological response from the two interviews. Both classical and item response theory methods were used. Factor analyses evaluated the dimensionality of each scale. Results The sample included 140 adolescent outpatients. All versions of the QIDS, save the parent interview, and the CDRS-R were very reliable (? ? 0.8). All four versions of the QIDS are reasonably effective and unidimensional. The CDRS-R was clearly at least two-dimensional. The CDRS-R was the most discriminating among low and extremely high levels of depression. The QIDS-SR16 was the most discriminating at moderate levels of depression. There was no relation between the QIDS scores and concurrent Axis III comorbidities. Conclusion The QIDS-C16 and the QIDS-SR16 are suitable for use in adolescents.

Quick-connect fasteners for assembling devices in space  

NASA Technical Reports Server (NTRS)

A quick-connect fastener of a relatively-simple straightforward design is arranged with a tubular body adapted to be engaged against an attachment fitting in coincidental alignment with an opening in that fitting. A tubular collet having flexible finger projecting from its forward end is arranged in the fastener body to be shifted forwardly by an elongated expander member coaxially arranged within the tubular collet for advancing the collet fingers into the opening in the attachment fitting. Biasing means are arranged between the elongated expander member and a rotatable actuator which is threadedly mounted within the tubular collet so as to be rotated for urging the expander member into engagement with the collet fingers. A first coupling member is arranged on the rotatable actuator to be accessible from outside of the fastener so that a second coupling member on the distal end of a flexible shaft can be introduced into the fastener body and coupled to the first coupling member to enable a typical actuating tool coupled to the shaft outside of the fastener body to be operated for advancing the outwardly-enlarged ends of the collet fingers into the opening in the attachment fitting and thereafter rotating the actuator member to expand the fingers to that attachment fitting. Upon expansion of the collet fingers, the biasing means impose a biasing force on the expander to releasably retain the fingers in their latching positions.

"They think surgery is just a quick fix"  

PubMed Central

Background To prevent weight regain, patients undergoing weight loss surgery are encouraged to change their exercise and dietary habits. Building on previous research, the aim of this study was to explore women's experiences of changing exercise habits – focusing on women participating in a group based rehabilitation program including surgical as well as non-surgical participants. Findings Based on interviews with the 11 women included in this study, as well as participant observation, two themes were identified; 1) Pushing ones tolerance limits, and 2) Rebutting the “quick fix” fallacy. Taken together, the findings showcase how being a part of this mixed group involved having to relate to social stigmas, as well as notions regarding successful and non-successful surgical outcomes. Although such notions may be useful in identifying potential challenges related to changing exercise habits, they do not illuminate the complexity of undergoing such changes following weight loss surgery. Conclusion The findings point to the need of acknowledging patients' own exceriences to determine how successful they are after surgery. Given the findings, I argue for the need to reconsider the notion of success in relation to group based interventions.

Quick monitoring of pozzolanic reactivity of waste ashes.  

PubMed

This article proposes a quick method of monitoring for pozzolanic reactivity of waste ashes by investigating the electrical conductivity of the suspension at an elevated temperature. This suspension is obtained by mixing tested pozzolan with an ordinary Portland cement (OPC) solution produced by mixing ordinary Portland cement with water. For comparison, silica fume, metakaolin, rice husk ash and river sand - whose pozzolanic reactivities range from reactive to inert - were used in the experimental investigation. The electrical conductivity of the suspension was continually recorded by using an electrical conductivity meter and stored by using a personal computer for a period of slightly over 1day. The indicative parameters that can be related to pozzolanic reactivity were discussed and analyzed in detail. It was found that it is possible to determine the pozzolanic reactivity of fly ash within 28h by using the proposed technique, as compared to 7 or 28 days for the determination of strength activity index according to ASTM. This technique would help concrete technologists to speedily investigate the quality of fly ash for use as a cement replacement in order to alleviate pollution caused by cement production and solve disposal problems of waste ashes.

New Biomarkers for the Quick Detection of Acute Kidney Injury  

PubMed Central

Acute kidney injury (AKI) is a common and strong problem in the diagnosis of which based on measurement of BUN and serum creatinine. These traditional methods are not sensitive and specific for the diagnosis of AKI. AKI is associated with increased morbidity and mortality in critically ill patients and a quick detection is impossible with BUN and serum creatinine. A number of serum and urinary proteins have been identified that may messenger AKI prior to a rise in BUN and serum creatinine. New biomarkers of AKI, including NGAL, KIM-1, cystatin-C, IL-18, and L-FABP, are more favourable tests than creatinine which have been identified and studied in several experimental and clinical training. This paper will discuss some of these new biomarkers and their potential as useful signs of AKI. We searched the literature using PubMed and MEDLINE with acute kidney injury, urine, and serum new biomarkers and the articles were selected only from publication types in English.

The research about the quick algorithm of subtracting the DTM  

NASA Astrophysics Data System (ADS)

There is some relationship between the Digital Surface Model (DSM) and the Digital Terrain Model (DTM). The contents they express are relative: DSM expresses the height we focus on about the surface of the ground, including the terrain and the objects on it, and DTM only gives the height of the terrain excluding the objects above it. DSM have the information of DTM, therefore it provides us a chance to subtract the DTM from the DSM. Mathematical morphology is a new method applied to Imagery processing and pattern recognition fields. It provides an effective method of subtracting DTM from DSM. But in practical application, the original calculations of these two are in low efficiency. Especially when it comes to a large template or huge block data, the computation speed can be a very headache question. This paper is studying the implementing process of the Open and the Close operators, especially the Erode and the Dilate calculations. Then we have developed two kinds of quick algorithms, which are aim to avoid the repeated calculation, and to enhance the efficiency sharply. The step of the two operations also should be refined, while the disposals are different from each other depending on the distinct configuration of these two kinds of algorithms.

Less quick returns--greater well-being.  

PubMed

The aim of this study was to design ergonomically improved shift schedules for nurses in primary health care shift work in order to enhance their health and well-being. The main change made was the reduction of quick returns (i.e., no more morning shifts immediately after an evening shift) in order to ensure more recovery time between work shifts. Six municipal hospital units participated in the intervention. Our aim was to maintain or improve the well-being and work ability of aged workers. The subjects (n=75) were divided into three age groups: 20-40, 41-52, and 53-62 yr. The introduction of more recovery time between evening and morning shifts significantly improved the subjects' sleep and alertness, well-being at work, perceived health, and leisure-time activities independently of their age. The effect on social and family life was also positive. Working in shifts was the most disruptive for the youngest group of nurses. The Work Ability Index score depended on the age group: it was lowest among the oldest age group, and did not change during the intervention. Ergonomic working time arrangements show positive effects on the well-being of health care workers of all ages. PMID:20720330

Quick XAFS System using Quasimonochromatic Undulator Radiation at SPring-8  

NASA Astrophysics Data System (ADS)

A time-resolved quick x-ray absorption fine structure (QXAFS) system was designed and constructed using high flux but low power quasimonochromatic undulator radiation at a helical undulator beamline, BL40XU at SPring-8. At 12 keV, a flux of 1013 - 1014 photons/sec/0.1 % bw. was generated over an energy range of 1 keV with a total power of 7 - 15 W. A compact Si(111) channel cut monochromator having no active cooling was utilized. The monochromator was mounted on a galvano-scanner stage within an experimental hutch. The stage could be oscillated at frequencies up to 100 Hz over a 1.4-degree range. The Pt L3-edge(11.6 keV) EXAFS spectra of Pt foil was measured in transmission and fluorescence modes up to k = 15 A-1 in a period of 50 ms/scan. In this report, the design of the QXAFS system and some preliminary experimental results are presented.

The quick motor function test: a new tool to rate clinical severity and motor function in Pompe patients.  

PubMed

Pompe disease is a lysosomal storage disorder characterized by progressive muscle weakness. With the emergence of new treatment options, psychometrically robust outcome measures are needed to monitor patients' clinical status. We constructed a motor function test that is easy and quick to use. The Quick Motor Function Test (QMFT) was constructed on the basis of the clinical expertise of several physicians involved in the care of Pompe patients; the Gross Motor Function Measure and the IPA/Erasmus MC Pompe survey. The test comprises 16 items. Validity and test reliability were determined in a cohort of 91 Pompe patients (5 to 76 years of age). In addition, responsiveness of the scale to changes in clinical condition over time was examined in a subgroup of 18 patients receiving treatment and 23 untreated patients. Interrater and intrarater reliabilities were good (intraclass correlation coefficients: 0.78 to 0.98 and 0.76 to 0.98). The test correlated strongly with proximal muscle strength assessed by hand held dynamometry and manual muscle testing (rs= 0.81, rs=0.89), and showed significant differences between patient groups with different disease severities. A clinical-empirical exploration to assess responsiveness showed promising results, albeit it should be repeated in a larger group of patients. In conclusion, the Quick Motor Function Test can reliably rate clinical severity and motor function in children and adults with Pompe disease. PMID:21912959

Older homebound women's perceived risk of being unable to reach help quickly: influence of situations involving age-peers.  

PubMed

The purpose of this facet of a longitudinal descriptive phenomenological study of the experience of reaching help quickly for older homebound women was to explore the personal-social context (life-world) of situations when age-peers had needed to reach help quickly (RHQ). Twenty-five women aged 85-95 (13 subscribers to a personal emergency response system and 12 non-subscribers) reported 80 peer situations. Life-world was characterized by sharing with peers the risk of being unable to RHQ. Knowledge of peer situations had varying degrees of influence on participants' decisions to adopt and use RHQ devices. Findings support the need for healthcare professionals to explore the influences of age-peer RHQ situations upon adoption and use of devices to RHQ by older homebound women. PMID:23070958

Comprehension deficits among older patients in a quick diagnostic unit  

PubMed Central

Background Higher prevalence of multiple illnesses and cognitive impairment among older patients pose a risk of comprehension difficulties, potentially leading to medication errors. Therefore, the objective of this study was to investigate comprehension of discharge instructions among older patients admitted to a Quick Diagnostic Unit (QDU). Methods One hundred and two patients discharged from the QDU answered a questionnaire covering understanding of their hospitalization and discharge plan. Patients’ ability to recall discharge instructions and awareness of comprehension deficits, ie, ability to identify the misconceived information, were evaluated by comparing the questionnaires with the discharge letters. The population was divided into an older group (age ?65 years) and a younger group. Results The older group (n=40) was less able to recall correct medication instructions when compared to the younger group (54% versus 78%, respectively; P=0.02). In multiple logistic regression analysis, correct recall of medication instructions was 4.2 times higher for the younger group compared to the older group (odds ratio 4.2, 95% confidence interval 1.5–11.9, P=0.007) when adjusted for sex and education. The older patients were less aware of their own comprehension deficits, and in respect to medication instructions awareness decreased 6.1% for each additional year of age (odds ratio 0.939, 95% confidence interval 0.904–0.98, P=0.001) when adjusted for sex and education. Conclusion Older patients were less able to recall correct medication instructions and less aware of their comprehension deficits after discharge from a QDU. The findings of the present study emphasize the importance of thorough communication and follow-up when treating older patients.

Spectral responsivity of the quantum wire infrared photodetectors  

NASA Astrophysics Data System (ADS)

The main objective of this manuscript is to assign the optical response wavelength range that can be covered by this type of semiconductor-based photodetectors, quantum wire infrared photodetectors (QRIPs). Also, the effect of quantum wire parameters (such as quantum wire density; lateral and transverse size), operating temperature, and applying bias voltage onto the behaviour of QRIPs are studied. From the obtained theoretical results, the maximum wavelength response is 40 ?m at certain values of quantum wire density, lateral size and operating temperatures, 9.9×10 7 cm -2, aQR=15 nm, T=60 K, respectively. Another important observation is that the obtained calculated responsivity denotes the maximum value at an operating temperature of T=60 K, from a temperature range of 40-90 K, for the same QR parameter values. Meanwhile, in the case of lower values of the average quantum wire densities, the responsivity is normally decreased with increasing temperature. Moreover, increasing the applied voltage value will increase the number of mobile charges into the active region, which results in increasing each of the dark and photo currents. Hence, degradation into the spectral responsivity and detectivity will be noticed. For that, the applied biasing voltage should be around a moderate value, 0.5 V. Generally, the QRIPs can give multicolour response for (mid-, and far) (10 ?m> ?>40 ?m) the IR region depending on the selectable compound parameters of QRIPs.

Foraging strategy quick response to temperature of Messor barbarus (Hymenoptera: Formicidae) in Mediterranean environments.  

PubMed

Animals principally forage to try to maximize energy intake per unit of feeding time, developing different foraging strategies. Temperature effects on foraging have been observed in diverse ant species; these effects are limited to the duration of foraging or the number of foragers involved. The harvester ant Messor barbarus L. 1767 has a specialized foraging strategy that consists in the formation of worker trails. Because of the high permeability of their body integument, we presume that the length, shape, and type of foraging trails of M. barbarus must be affected by temperature conditions. From mid-June to mid-August 1999, we tested the effect on these trail characteristics in a Mediterranean forest. We found that thermal stress force ants to use a foraging pattern based on the variation of the workers trail structure. Ants exploit earlier well-known sources using long physical trails, but as temperatures increases throughout the morning, foragers reduce the length of the foraging column gradually, looking for alternative food sources in nonphysical trails. This study shows that animal forage can be highly adaptable and versatile in environments with high daily variations. PMID:18801249

Development of a Quick Look Pandemic Influenza Modeling and Visualization Tool  

SciTech Connect

Federal, State, and local decision makers and public health officials must prepare and exercise complex plans to contend with a variety of possible mass casualty events, such as pandemic influenza. Through the provision of quick look tools (QLTs) focused on mass casualty events, such planning can be done with higher accuracy and more realism through the combination of interactive simulation and visualization in these tools. If an event happens, the QLTs can then be employed to rapidly assess and execute alternative mitigation strategies, and thereby minimize casualties. This can be achieved by conducting numerous 'what-if' assessments prior to any event in order to assess potential health impacts (e.g., number of sick individuals), required community resources (e.g., vaccinations and hospital beds), and optimal mitigative decision strategies (e.g., school closures) during the course of a pandemic. In this presentation, we overview and demonstrate a pandemic influenza QLT, discuss some of the modeling methods and construct and visual analytic components and interface, and outline additional development concepts. These include the incorporation of a user selectable infectious disease palette, simultaneous visualization of decision alternatives, additional resource elements associated with emergency response (e.g., first responders and medical professionals), and provisions for other potential disaster events.

Delineation of a quick clay zone at Smørgrav, Norway, with electromagnetic methods under geotechnical constraints  

NASA Astrophysics Data System (ADS)

In many coastal areas of North America and Scandinavia, post-glacial clay sediments have emerged above sea level due to iso-static uplift. These clays are often destabilised by fresh water leaching and transformed to so-called quick clays as at the investigated area at Smørgrav, Norway. Slight mechanical disturbances of these materials may trigger landslides. Since the leaching increases the electrical resistivity of quick clay as compared to normal marine clay, the application of electromagnetic (EM) methods is of particular interest in the study of quick clay structures. For the first time, single and joint inversions of direct-current resistivity (DCR), radiomagnetotelluric (RMT) and controlled-source audiomagnetotelluric (CSAMT) data were applied to delineate a zone of quick clay. The resulting 2-D models of electrical resistivity correlate excellently with previously published data from a ground conductivity metre and resistivity logs from two resistivity cone penetration tests (RCPT) into marine clay and quick clay. The RCPT log into the central part of the quick clay identifies the electrical resistivity of the quick clay structure to lie between 10 and 80 ? m. In combination with the 2-D inversion models, it becomes possible to delineate the vertical and horizontal extent of the quick clay zone. As compared to the inversions of single data sets, the joint inversion model exhibits sharper resistivity contrasts and its resistivity values are more characteristic of the expected geology. In our preferred joint inversion model, there is a clear demarcation between dry soil, marine clay, quick clay and bedrock, which consists of alum shale and limestone.

Anticipatory synergy adjustments: Preparing a quick action in an unknown direction  

PubMed Central

We studied a mechanism of feed-forward control of a multi-finger action, namely anticipatory synergy adjustments (ASAs) prior to a quick force correction in response to a change in the gain of the visual feedback. Synergies were defined as co-varied across trials adjustments of commands to fingers that stabilized (decreased variance of) the total force. We hypothesized that ASAs would be highly sensitive to prior information about the timing of the action but not to information on its direction, i.e., on whether the gain would go up or down. The subjects produced accurate constant total force by pressing with four fingers on individual force sensors. The feedback signal could change from veridical (the sum of finger forces) to modified, with the middle finger force multiplied by 0.2 or by 1.8. The timing of the gain change and its direction could be known or unknown to the subject in advance. When the timing of the gain change was known, ASA was seen as a drop in the synergy index starting about 250–300 ms prior to the first visible correction of the total force. When the gain change timing was unknown, ASAs started much later, less than 100 ms prior to the total force correction. The magnitude of synergy index changes was significantly larger under the “time known” conditions. Information on the direction of the visual gain change had no effect on the ASA timing, while the ASA magnitude was somewhat larger when this information was not available to the subject. After the total force correction, the synergy index was significantly larger for the force signal computed using the modified gain values as compared to the synergy index value for the actual total force. We conclude that ASAs represent an important feed-forward motor control mechanism that allows preparing for a quick action even when the direction of the action is not known in advance. The results emphasize the subtle control of multi-finger synergies that are specific to the exact contributions of individual fingers to performance variables. The data fit well the central back-coupling hypothesis of synergies and the idea of control with referent body configurations.

Build great web search applications quickly with Solr and Blacklight  

NASA Astrophysics Data System (ADS)

The NRAO faced performance and usability issues after releasing a single-search-box ("Google-like") web application to query data across all NRAO telescope archives. Running queries with several relations across multiple databases proved to be very expensive in compute resources. An investigation for a better platform led to Solr and Blacklight, a solution stack which allows in-house development to focus on in-house problems. Solr is an Apache project built on Lucene to provide a modern search server with a rich set of features and impressive performance. Blacklight is a web user interface (UI) for Solr primarily developed by libraries at the University of Virginia and Stanford University. Though Blacklight targets libraries, it is highly adaptable for many types of search applications which benefit from the faceted searching and browsing, minimal configuration, and flexible query parsing of Solr and Lucene. The result: one highly reused codebase provides for millisecond response times and a flexible UI. Not just for observational data, NRAO is rolling out Solr and Blacklight across domains of library databases, telescope proposals, and more -- in addition to telescope data products, where integration with the Virtual Observatory is on-going.

WAIS prediction for an older clinical population using the Quick Test.  

PubMed

Data were analyzed to estimate WAIS Full Scale IQs from Quick Test scores. Ss were 26 mental health center patients ranging in age from 46 to 78 years (X = 58.46, SD = 8.78). In predicting WAIS Full Scale IQs, Quick Test Form 3 age-corrected and uncorrected scores accounted for 66 and 70% of the variance respectively (p less than .001). Two- and three-variable regression models did not yield meaningful increases in variance. Quick Test Form 3 is recommended when a brief measure of intellectual functioning for an aged clinical population is needed. PMID:7263890

Development and validation of a quick easily used biochemical assay for evaluating the viability of small immobile arthropods.  

PubMed

Quickly, accurately, and easily assessing the efficacy of treatments to control sessile arthropods (e.g., scale insects) and stationary immature life stages (e.g., eggs and pupae) is problematic because it is difficult to tell whether treated organisms are alive or dead. Current approaches usually involve either maintaining organisms in the laboratory to observe them for development, gauging their response to physical stimulation, or assessing morphological characters such as turgidity and color. These can be slow, technically difficult, or subjective, and the validity of methods other than laboratory rearing has seldom been tested. Here, we describe development and validation of a quick easily used biochemical colorimetric assay for measuring the viability of arthropods that is sufficiently sensitive to test even very small organisms such as white fly eggs. The assay was adapted from a technique for staining the enzyme hexokinase to signal the presence of adenosine triphosphate in viable specimens by reducing a tetrazolium salt to formazan. Basic laboratory facilities and skills are required for production of the stain, but no specialist equipment, expertise, or facilities are needed for its use. PMID:24224241

Development of a database of quick-look plots for the earth and space science data  

NASA Astrophysics Data System (ADS)

A database of quick-look plots of the earth and space science data has been developed and called DAGIK (Data-showcase system for Geoscience in KML). Although there are many projects that make the access and usage of the earth and space data much easier, the users still have difficulties to find the data with that they are not familiar. Quick-look plot is an easy way to show the novice users outline of the data; how the data looks like, when and where the data was observed. Most of the databases of the earth and space data provide quick-look plot on their WWW sites to help users to browse the data. As the metadata bases help to find data, a "one-stop" database of quick-look plots is useful for users to find data that the users don't use regularly. To construct such a database of quick-look plots, metadata of the plots should be embedded in the plot files. KML is one of the data formats that can contain plots and metadata. It is in XML. There are several browsers of KML, such as Google Earth and NASA world wind. DAGIK is a network-based database using KML files for the geoscience plots. We term such database of quick-look plots as "data-showcase system". It is a showcase of data for users to browse. The users who find an interesting data will use database or meta database following the link in the quick-look plots that contains metadata. We believe that the metadata of plots is a useful tool for easy data access as the metadata of data. In the presentation, we introduce DAGIK as an implementation of the data-showcase system.

QuickProbs--a fast multiple sequence alignment algorithm designed for graphics processors.  

PubMed

Multiple sequence alignment is a crucial task in a number of biological analyses like secondary structure prediction, domain searching, phylogeny, etc. MSAProbs is currently the most accurate alignment algorithm, but its effectiveness is obtained at the expense of computational time. In the paper we present QuickProbs, the variant of MSAProbs customised for graphics processors. We selected the two most time consuming stages of MSAProbs to be redesigned for GPU execution: the posterior matrices calculation and the consistency transformation. Experiments on three popular benchmarks (BAliBASE, PREFAB, OXBench-X) on quad-core PC equipped with high-end graphics card show QuickProbs to be 5.7 to 9.7 times faster than original CPU-parallel MSAProbs. Additional tests performed on several protein families from Pfam database give overall speed-up of 6.7. Compared to other algorithms like MAFFT, MUSCLE, or ClustalW, QuickProbs proved to be much more accurate at similar speed. Additionally we introduce a tuned variant of QuickProbs which is significantly more accurate on sets of distantly related sequences than MSAProbs without exceeding its computation time. The GPU part of QuickProbs was implemented in OpenCL, thus the package is suitable for graphics processors produced by all major vendors. PMID:24586435

Quick-MESS: A Fast Statistical Tool for Exoplanet Imaging Surveys  

NASA Astrophysics Data System (ADS)

Several tools have been developed in the past few years for the statistical analysis of the exoplanet search surveys, mostly using a combination of Monte Carlo simulations or a Bayesian approach. Here we present Quick-MESS, a grid-based, non-Monte Carlo tool aimed to perform statistical analyses on results from direct imaging surveys, as well as help with the planning of these surveys. Quick-MESS uses the (expected) contrast curves for direct imaging surveys to assess for each target the probability that a planet of a given mass and semimajor axis can be detected. By using a grid-based approach, Quick-MESS is typically more than an order of magnitude faster than tools based on Monte Carlo sampling of the planet distribution. In addition, Quick-MESS is extremely flexible, enabling the study of a large range of parameter space for the mass and semimajor axes distributions without the need of resimulating the planet distribution. In order to show examples of the capabilities of Quick-MESS, we present the analysis of the Gemini Deep Planet Survey and the predictions for upcoming surveys with extreme-AO instruments.

QuickStar: System design, capabilities, and tactical applications of a small, smart space system  

NASA Astrophysics Data System (ADS)

The QuickStar System is not a concept--it is a flight-proven design. QuickStar is a small, highly capable, low-cost, lightweight spacecraft using modern design techniques that can carry tactical assets into space at a tenth of the cost of current systems. System design, relevant technologies, payload capabilities (mass, power, data rate, pointing, volume), and tactical mission applications of this lightweight satellite are described. As part of the overall small satellite system architecture, a portable, low-cost multipurpose ground station to support production, test, launch, and orbit operations of the space segment is also available. The versatility and transportability built into the ground station allows placement at any government installation or field site. The prototype QuickStar space segment was developed to ride as a secondary payload on a McDonnell Douglas Delta 2 series expendable launch vehicle (ELV). With the extra performance provided by the Delta 2 or other ELV of similar configuration, as many as four satellites could be orbited at one time. In addition, the paper describes a QuickStar satellite configuration, incorporating the same subsystems and capabilities as the prototype QuickStar, designed for stand-alone ELV (Scout or Pegasus) launchings. The program schedule for the design, fabrication, and test of a QuickStar satellite system reflects the fast-paced environment of a low-cost program. Minimal paper and much concurrent engineering goes into a schedule that provides a flight-ready spacecraft and supporting ground station in only 15 months.

Quick-scanning X-ray absorption fine structure (XAFS) measurements were performed in transmission mode using a PILATUS 100K pixel array detector (PAD). The method can display a two-dimensional image for a large area of the order of a centimetre with a spatial resolution of 0.2?mm at each energy point in the XAFS spectrum. The time resolution of the quick-scanning method ranged from 10?s to 1?min per spectrum depending on the energy range. The PAD has a wide dynamic range and low noise, so the obtained spectra have a good signal-to-noise ratio.

On the integrated use of geophysics for quick-clay mapping: The Hvittingfoss case study, Norway  

NASA Astrophysics Data System (ADS)

Quick-clay landslides are a known hazard in formerly glaciated coastal areas; hence, large efforts are devoted to map the distribution of quick clays. In this paper, we focus on one particular Norwegian site (Hvittingfoss, 80 km south-west of Oslo), which was remediated against potential landsliding in 2008. A set of geophysical methods including Electrical Resistivity Tomography, P-wave seismic refraction tomography, S-wave seismic reflection profiling, and Ground Penetrating Radar were jointly analysed and complemented with laboratory data and in situ geotechnical measurements (i.e., seismic and resistivity Cone Penetration Testing with pore pressure measurement) in order to improve our geological understanding of the site and to establish a suitable, integrated and multi-disciplinary approach to better map the special extent of the quick-clay zone. The integration of the different geophysical methods and geotechnical measurements allow a more precise imaging and characterisation, both spatially and vertically, of the sedimentary sequences and of the underlying bedrock. The resulting geological model is then populated with the quantitative parameters derived from the geophysical measurements. Considering the inherent complexity of quick-clay mapping, the collected data illustrate the benefit of an integrated approach, and emphasise the need for high resolution, proper imaging, calibration and ultimately joint inversion of the different data.

A multidisciplinary geophysical, geotechnical and hydrogeological investigation of quick-clay landslides in Sweden  

NASA Astrophysics Data System (ADS)

In Spring 2011, the Society of Exploration Geophysicists (SEG) through its Geoscientists Without Borders (GWB) program sponsored our project to study clay-related landslides in the Nordic countries. This project will study quick clay or rapid earth flow landslides in Sweden. Undisturbed quick clay resembles a water-saturated gel. When a mass of quick clay undergoes sufficient stress, it instantly turns into a flowing ooze, a process known as liquefaction. A small block of quick clay can liquefy from a stress change due to as little as a modest blow from a human hand, while a larger deposit is mainly vulnerable to greater stress changes, such as increased saturation by excess rainwater. Despite their abundance, our geophysical understanding of clay behavior in terms of both changes in the geometrical shape (clay formations) and changes in the physical properties are limited and require a better understanding. Quick clay landslides are not particularly constrained to steep slopes and have been known to slide even in low-to-moderate angle slopes. Geophysical investigations began in September 2011 over a known landslide scar near the Göta river in southwest Sweden, an area known to contain quick clays in parts of it. The investigations involved 2D and 3D P- and S-wave source and receiver surveys, geoelectrics, controlled-source and radio-magnetotellurics, ground gravity and magnetic surveys. These data in combination with existing geotechnical information and hydrogeological investigations should allow better insight into the mechanism(s) governing clay-related landslides in the Nordic countries and to provide high-resolution images of subsurface structures down to the bedrock. We will present preliminary results from the seismic investigations, including the 2D and 3D reflection and refraction surveys. The reflection seismic data show excellent quality and image the bedrock topography and internal layering above it down to about 100 m. Tomography results suggest the presence of low-velocity zones associated with some of the reflections, making the integration of the two methods interesting. A shear-wave survey also shows excellent data quality and very high resolution. It helps to image fine structures above the bedrock, as well as the bedrock topography. The level of the detail already revealed by the seismic data demonstrates that the project will be able to image fine structures associated with quick-clay landslides that are important and valuable for any site assessment.

TEC ingestion into NeQuick 2 to model the East African equatorial ionosphere  

NASA Astrophysics Data System (ADS)

NeQuick 2 ionospheric empirical model depends on global ionospheric coefficients that are estimated from unevenly distributed ionosonde measurements. In regions, like Africa, where very few observational data were available until recently, the model estimated the ionospheric peak parameters by interpolation. When one wants to employ the model to specify the ionosphere where very few data have been used for model development, the performances of the model need careful validation. This study investigates the performances of NeQuick 2 in the East African region by assisting the model with measurements from a single Global Positioning System (GPS) receiver, which has been deployed recently. This can be done by first calculating an effective ionization level that drives NeQuick 2 to compute slant total electron content (sTEC) which fits, in the least square sense, with the measurements taken from a single GPS receiver. We then quantify the performances of NeQuick 2 in reproducing the measured TEC by running the model at four other locations, where GPS stations are available, using the same effective ionization level that we calculated from a single GPS station as a driver of the model. Finally, the performances of the model before and after data ingestion have been investigated by comparing the model results with the experimental sTEC and vertical TEC (vTEC) obtained from the four test stations. Three months data during low solar activity conditions have been used for this study. We have shown that the capability of NeQuick 2, in describing the East African region of the ionosphere, can be improved substantially by data ingestion. We found that the model after ingestion reproduces the experimental TEC better as far as about 620 km away from the reference station than that before adaptation. The statistical comparisons of the performances of the model in reproducing sTEC before and after ingestion are also discussed in this study.

Rapidly Measuring the Speed of Unconscious Learning: Amnesics Learn Quickly and Happy People Slowly  

PubMed Central

Background We introduce a method for quickly determining the rate of implicit learning. Methodology/Principal Findings The task involves making a binary prediction for a probabilistic sequence over 10 minutes; from this it is possible to determine the influence of events of a different number of trials in the past on the current decision. This profile directly reflects the learning rate parameter of a large class of learning algorithms including the delta and Rescorla-Wagner rules. To illustrate the use of the method, we compare a person with amnesia with normal controls and we compare people with induced happy and sad moods. Conclusions/Significance Learning on the task is likely both associative and implicit. We argue theoretically and demonstrate empirically that both amnesia and also transient negative moods can be associated with an especially large learning rate: People with amnesia can learn quickly and happy people slowly.

Quick application/release nut with engagement indicator (commercial application of an innovative nut design)  

NASA Technical Reports Server (NTRS)

This is an assembly which permits a fastener to be inserted or removed from either side with an indicator of fastener engagement. The nut has a plurality of segments, preferably at least three segments, which are internally threaded, spring loaded apart by an internal spring, and has detents on opposite sides which force the nut segments into operative engagement with a threaded member when pushed in and release the segments for quick insertion or removal of the fastener when moved out. When the nut is installed, end pressure on the detents presses the nut segments into operative engagement with a threaded member where continued rotation locks the structure together with the detents depressed to indicate positive locking engagement of the nut. On removal, counterclockwise rotation relieves the endwise pressure on the detents, permitting internal springs to force the detents outward, allowing the nut segments to move outward and separate to permit quick removal of the fastener.

The Geo Quick Ride (GQR) Program: Providing Inexpensive and Frequent Access to Space  

NASA Technical Reports Server (NTRS)

This paper examines piggybacking NASA, university, and industry payloads on commercial geosynchronous satellites. NASA's RSDO Office awarded Geo Quick Ride (GQR) study contracts in 1998 to spacecraft manufactures to examine the issues with flying secondary payloads. The study results were very promising. Commercial communication satellites have frequent flights and significant unused resources that could be used to fly secondary payloads. However, manifesting secondary payloads on a commercial revenue-generating satellite is a complex problem to solve. The solution requires multiple simultaneous approaches in order to be successful. There are business, economic, technical, schedule, and organizational issues to be resolved. This paper examines the Geo Quick Ride (GQR) concept, discusses the development issues, and describes how this concept solves many of these issues.

Preliminary engineering study: Quick opening valve MSFC high Reynolds number wind tunnel  

NASA Technical Reports Server (NTRS)

FluiDyne Engineering Corporation has conducted a preliminary engineering study of a quick-opening valve for the MSFC High Reynolds Number Wind Tunnel under NASA Contract NAS8-35056. The subject valve is intended to replace the Mylar diaphragm system as the flow initiation device for the tunnel. Only valves capable of opening within 0.05 sec. and providing a minimum of 11.4 square feet of flow area were considered. Also, the study focused on valves which combined the quick-opening and tight shutoff features in a single unit. A ring sleeve valve concept was chosen for refinement and pricing. Sealing for tight shutoff, ring sleeve closure release and sleeve actuation were considered. The resulting cost estimate includes the valve and requisite modifications to the facility to accommodate the valve as well as the associated design and development work.

Evidence for a common mechanism for spontaneous rhythmic contraction and myogenic contraction induced by quick stretch in detrusor smooth muscle.  

PubMed

Detrusor smooth muscle exhibits myogenic contraction in response to a quick stretch (QS) as well as spontaneous rhythmic contraction (SRC); however, whether the same population of actomyosin crossbridges with a common regulatory mechanism is responsible for these two types of contraction has not been determined. Detrusor strips from New Zealand white rabbit bladders were allowed to develop SRC at a reference muscle length (L ref), or rhythmic contraction (RC) was induced with tetraethylammonium (TEA). Multiple 10-msec stretches of 15% L ref were then imposed at L ref randomly during the rhythm cycle, and the nadir-to-peak (NTP) tension amplitude of the resulting myogenic contraction was measured. The amplitude and period of the rhythm cycle were measured prior to each QS. NTP was larger when a QS was imposed during a portion the cycle when tension was smaller (n = 3 each SRC and TEA-induced RC). These data suggest that when the rhythmic mechanism was mostly inactive and tension was near a minimum, a larger portion of a shared population of crossbridges was available to produce a myogenic response to a QS. Rho kinase, cyclooxygenase-1, and cyclooxygenase-2 inhibitors (H-1152, SC-560, and NS-398) affected SRC amplitude and NTP amplitude following a QS to the same degree (n = 3 each drug), providing additional evidence to support the hypothesis that a common mechanism is responsible for SRC and myogenic contraction due to QS. If a common mechanism exists, then QS is a potential mechanical probe to study SRC regulation and its alteration in overactive bladder. PMID:24400167

Web services interface for Space Weather: NeQuick 2 web and experimental TEC Calibration  

NASA Astrophysics Data System (ADS)

A web front-end has been recently developed and released to allow retrieving and plotting ionospheric parameters computed by the latest version of the model, NeQuick 2. NeQuick is a quick-run ionospheric electron density model particularly designed for trans-ionospheric propagation applications. It has been developed at the Aeronomy and Radiopropagation Laboratory (now T/ICT4D Laboratory) of the Abdus Salam International Centre for Theoretical Physics (ICTP) - Trieste, Italy with the collaboration of the Institute for Geophysics, Astrophysics and Meteorology (IGAM) of the University of Graz, Austria. To describe the electron density of the ionosphere up to the peak of the F2 layer, NeQuick uses a profile formulation which includes five semi-Epstein layers with modelled thickness parameters. Through a simple web interface users can exploit all the model features including the possibility of computing the electron density and visualizing the corresponding Total Electron Content (TEC) along any ground-to-satellite straight line ray-path. Indeed, the TEC is the ionospheric parameter retrieved from the GPS measurements. It complements the experimental data obtained with diverse kinds of sensors and can be considered a major source of ionospheric information. Since the TEC is not a direct measurement, a "de-biasing" procedure or calibration has to be applied to obtain the relevant values from the raw GPS observables. Using the observation and navigation RINEX files corresponding to a single receiver as input data, the web application allows the user to compute the slant and/or vertical TEC following the concept of the "arc-by-arc" offsets estimation. The combined use of both tools, freely available from the T/ICT4D Web site, will allow the comparison of experimentally derived slant and vertical TEC with modelled values. An online demonstration of the capabilities of the mentioned web services will be illustrated.

Molecular Evolution of Slow and Quick Anion Channels (SLACs and QUACs/ALMTs)  

PubMed Central

Electrophysiological analyses conducted about 25?years ago detected two types of anion channels in the plasma membrane of guard cells. One type of channel responds slowly to changes in membrane voltage while the other responds quickly. Consequently, they were named SLAC, for SLow Anion Channel, and QUAC, for QUick Anion Channel. Recently, genes SLAC1 and QUAC1/ALMT12, underlying the two different anion current components, could be identified in the model plant Arabidopsis thaliana. Expression of the gene products in Xenopus oocytes confirmed the quick and slow current kinetics. In this study we provide an overview on our current knowledge on slow and quick anion channels in plants and analyze the molecular evolution of ALMT/QUAC-like and SLAC-like channels. We discovered fingerprints that allow screening databases for these channel types and were able to identify 192 (177 non-redundant) SLAC-like and 422 (402 non-redundant) ALMT/QUAC-like proteins in the fully sequenced genomes of 32 plant species. Phylogenetic analyses provided new insights into the molecular evolution of these channel types. We also combined sequence alignment and clustering with predictions of protein features, leading to the identification of known conserved phosphorylation sites in SLAC1-like channels along with potential sites that have not been yet experimentally confirmed. Using a similar strategy to analyze the hydropathicity of ALMT/QUAC-like channels, we propose a modified topology with additional transmembrane regions that integrates structure and function of these membrane proteins. Our results suggest that cross-referencing phylogenetic analyses with position-specific protein properties and functional data could be a very powerful tool for genome research approaches in general.

Synaptic vesicle exocytosis captured by quick freezing and correlated with quantal transmitter release  

PubMed Central

We describe the design and operation of a machine that freezes biological tissues by contact with a cold metal block, which incorporates a timing circuit that stimulates frog neuromuscular junctions in the last few milliseconds before thay are frozen. We show freeze-fracture replicas of nerve terminals frozen during transmitter discharge, which display synpatic vesicles caught in the act of exocytosis. We use 4-aminopyridine (4-AP) to increase the number of transmitter quanta discharged with each nerve impulse, and show that the number of exocytotic vesicles caught by quick-freezing increases commensurately, indicating that one vesicle undergoes exocytosis for each quantum that is discharged. We perform statistical analyses on the spatial distribution of synaptic vesicle discharge sites along the "active zones" that mark the secretory regions of these nerves, and show that individual vesicles fuse with the plasma membrane independent of one another, as expected from physiological demonstrations that quanta are discharged independently. Thus, the utility of quick- freezing as a technique to capture biological processes as evanescent as synaptic transmission has been established. An appendix describes a new capacitance method to measure freezing rates, which shows that the "temporal resolution" of our quick-freezing technique is 2 ms or better.

QuickSNP: an automated web server for selection of tagSNPs.  

PubMed

Although large-scale genetic association studies involving hundreds to thousands of SNPs have become feasible, the associated cost is substantial. Even with the increased efficiency introduced by the use of tagSNPs, researchers are often seeking ways to maximize resource utilization given a set of SNP-based gene-mapping goals. We have developed a web server named QuickSNP in order to provide cost-effective selection of SNPs, and to fill in some of the gaps in existing SNP selection tools. One useful feature of QuickSNP is the option to select only gene-centric SNPs from a chromosomal region in an automated fashion. Other useful features include automated selection of coding non-synonymous SNPs, SNP filtering based on inter-SNP distances and information regarding the availability of genotyping assays for SNPs and whether they are present on whole genome chips. The program produces user-friendly summary tables and results, and a link to a UCSC Genome Browser track illustrating the position of the selected tagSNPs in relation to genes and other genomic features. We hope the unique combination of features of this server will be useful for researchers aiming to select markers for their genotyping studies. The server is freely available and can be accessed at the URL http://bioinformoodics.jhmi.edu/quickSNP.pl. PMID:17517769

State concentration exponent as a measure of quickness in Kauffman-type networks  

NASA Astrophysics Data System (ADS)

We study the dynamics of randomly connected networks composed of binary Boolean elements and those composed of binary majority vote elements. We elucidate their differences in both sparsely and densely connected cases. The quickness of large network dynamics is usually quantified by the length of transient paths, an analytically intractable measure. For discrete-time dynamics of networks of binary elements, we address this dilemma with an alternative unified framework by using a concept termed state concentration, defined as the exponent of the average number of t-step ancestors in state transition graphs. The state transition graph is defined by nodes corresponding to network states and directed links corresponding to transitions. Using this exponent, we interrogate the dynamics of random Boolean and majority vote networks. We find that extremely sparse Boolean networks and majority vote networks with arbitrary density achieve quickness, owing in part to long-tailed in-degree distributions. As a corollary, only relatively dense majority vote networks can achieve both quickness and robustness.

Four soils, designated QR, QU, SR and SU, derived from Quaternary red earth and Tertiary red sandstone, were collected from rice and upland field. The results indicated that, without ammonium input, the responses of nitrification in upland soils to air-drying were insignificant (p > 0.05). The nitrification ratio in fresh and air-dried samples of soil QU were 48% and 54% respectively, and 76% and 78% for SU; however, air-drying did have a significant effect on the nitrification in paddy soils (p < 0.01). Nitrification ratios were 40% and 89% for fresh and air-dried samples of QR, 76% and 94% for SR, and there was a lag-phase of the nitrification in air-dried paddy soils. Ammonium input would accelerate nitrification and make the nitrification ratios of fresh samples significantly higher than those of air-dried ones. In generally, land-use type presents a significant impact on the response of nitrification to air-drying effect, and there was a significant interaction of land-use type and fertilization.

Liu-stain quick cytodiagnosis of ultrasound-guided fine needle aspiration in diagnosis of liver tumors  

PubMed Central

AIM: To combine ultrasound-guided fine-needle aspiration (US-FNA) and Liu (Riu) stain to make a quick study on liver tumor lesions. METHODS: Two hundred and twenty-eight aspirations from 232 patients were completely studied. The operator himself made the quick cytodiagnosis of US-FNA smear stained by Liu method within thirty minutes. The US-FNA specimen was also sent to the pathological department for cytological study and cellblock histology. The result of our Liu-stain quick cytodiagnosis in each patient was confirmed by the final cytopathological diagnosis from pathological report. RESULTS: Among 228 samples, the quick cytodiagnosis revealed 146 malignancies, 81 benign lesions and one inadequate specimen. Cytopathological diagnosis from the pathological department revealed 150 malignancies, and 78 benign lesions. Four well-differentiated hepatocellular carcinomas (HCCs) were under-diagnosed by quick cytodiagnosis as benign and 3 benign lesions were over-diagnosed as well-differentiated HCCs. Compared with cytopathological diagnosis, quick cytodiagnosis correctly diagnosed 143 malignancies and 77 benign lesions. Except for the one inadequate specimen in quick cytodiagnosis, the accuracy of quick cytodiagnosis was 96.9% (220/227), and its sensitivity, specificity and positive and negative predictive values were 97.9%, 95.1%, 97.3% and 96.3%, respectively. CONCLUSION: Liu-stain quick cytodiagnosis is a fast, convenient, safe and effective method for hepatologists in clinic practice to diagnose liver tumor. In few cases of well-differentiated HCC, Liu-stain quick cytodiagnosis has its limitation.

Multi-Scale Validation of Forest Insect Mortality Using QuickBird and Aerial Imagery  

NASA Astrophysics Data System (ADS)

Insects are major disturbances in forested ecosystems, affecting forest succession, carbon cycling, and fuel loads. Insect-caused tree mortality causes significant change in forest structure as dead trees lose their needles and eventually fall to the ground. To manage forests and establish natural resource policy, accurate estimates of the extent of insect disturbance are needed. Mountain pine beetles (Dendroctonus ponderosae Hopkins), one of the most damaging insect species, have affected large forested areas in the United States and Canada. Our goal is to map landscape-level tree mortality caused by insect outbreaks across the western United States using satellite remote sensing. Here we report on the methods we are developing and applying to an outbreak of mountain pine beetle in Colorado as well as the means of evaluating the classification using field measurements and finer spatial resolution aerial imagery. In August 2008, 36 forest inventory plots were established in an area affected by mountain pine beetle in the Arapaho National Forest in the Rocky Mountains of Colorado, USA. A digital aerial multispectral image with a spatial resolution of 30 cm and a QuickBird image with a spatial resolution of 2.4 m were acquired in the same area. We are employing a nested validation approach using the aerial imagery and QuickBird imagery to ultimately validate a Landsat-based insect disturbance detection product. Tree-level field measurements are used to evaluate classified the aerial imagery. The classified aerial imagery is subsequently used to evaluate classified QuickBird imagery, which in turn is used to evaluate the Landsat product. The outcomes of finer spatial level classification can be used to increase understanding of the coarser spatial image classification and provide means to investigate disturbance level thresholds for the detection of insect outbreaks using the coarser resolution imagery.

Freezing curve-based monitoring to quickly evaluate the viability of biological materials subject to freezing or thermal injury.  

PubMed

This paper is aimed at investigating the roles of freezing dynamics of a liquid droplet to characterize the properties of the material. In particular, freezing curve-based monitoring was proposed to quickly evaluate the viability of biological materials subject to freezing, re-warming, or other kinds of injury, which is an extremely important issue in practices such as cryobiology, hyperthermia, or freshness evaluation of bio-samples. An integrated micro analysis device was fabricated which is simple in structure and cheap to make. Preliminary freezing results demonstrated that minor changes in a biological material due to freezing or warming injury might result in a significant deviation of its freezing curve from that of the intact biomaterials. Several potential thermal indexes to quantify the material features were pointed out. Further, experiments were performed on some freezing and thawing processes of small amount of water on a cooling surface to test the effects of droplet sizes, measurement sites, cooling strength, and cooling geometry, etc., on the freezing responses of a water droplet. Their implementation in developing a new micro analysis system were suggested. This freezing curve-based monitoring method may open a new strategy for the evaluation of biomaterials subject to destruction in diverse fields. PMID:12844203

HARD REAL TIME QUICK EXAFS DATA ACQUISITION WITH ALL OPEN SOURCE SOFTWARE ON A COMMODITY PERSONAL COMPUTER.  

SciTech Connect

We describe here the data acquisition subsystem of the Quick EXAFS (QEXAFS) experiment at the National Synchrotron Light Source of Brookhaven National Laboratory. For ease of future growth and flexibility, almost all software components are open source with very active maintainers. Among them, Linux running on x86 desktop computer, RTAI for real-time response, COMEDI driver for the data acquisition hardware, Qt and PyQt for graphical user interface, PyQwt for plotting, and Python for scripting. The signal (A/D) and energy-reading (IK220 encoder) devices in the PCI computer are also EPICS enabled. The control system scans the monochromator energy through a networked EPICS motor. With the real-time kernel, the system is capable of deterministic data-sampling period of tens of micro-seconds with typical timing-jitter of several micro-seconds. At the same time, Linux is running in other non-real-time processes handling the user-interface. A modern Qt-based controls-front end enhances productivity. The fast plotting and zooming of data in time or energy coordinates let the experimenters verify the quality of the data before detailed analysis. Python scripting is built-in for automation. The typical data-rate for continuous runs are around ten mega-bytes per minute.

Quick, controlled synthesis of ultrathin Bi2Se3 nanodiscs and nanosheets.  

PubMed

Ultrathin (4-6 nm) single-crystal Bi(2)Se(3) nanodiscs and nanosheets were synthesized through a simple and quick solution process. The growth mechanism was investigated in detail. Crystal seeds grew via 2D self-attachment of small nanoparticles followed by epitaxial recrystallization into single crystals. The lateral dimension of the nanodiscs increased and their shape changed from circles to hexagons as the reaction temperature increased. Positively charged polymer surfactants greatly enlarged the lateral dimension to produce nanosheets with uniform thickness. PMID:22296213

Benchmarking the codes VORPAL, OSIRIS, and QuickPIC with Laser Wakefield Acceleration Simulations  

NASA Astrophysics Data System (ADS)

Three-dimensional laser wakefield acceleration (LWFA) simulations have recently been performed to benchmark the commonly used particle-in-cell (PIC) codes VORPAL, OSIRIS, and QuickPIC. The simulations were run in parallel on over 100 processors, using parameters relevant to LWFA with ultra-short Ti-Sapphire laser pulses propagating in hydrogen gas. Both first-order and second-order particle shapes were employed. We present the results of this benchmarking exercise, and show that accelerating gradients from full PIC agree for all values of a0 and that full and reduced PIC agree well for values of a0 approaching 4.

A 3D DEM-LBM approach for the assessment of the quick condition for sands  

NASA Astrophysics Data System (ADS)

We present a 3D numerical model to assess the quick condition (the onset of the boiling phenomenon) in a saturated polydisperse granular material. We use the Discrete Element Method (DEM) to study the evolution of the vertical intergranular stress in a granular sample subjected to an increasing hydraulic gradient. The hydrodynamic forces on the grains of the sample are computed using the Lattice Boltzmann Method (LBM). The principal assumption used is that grains remain at rest until the boiling onset. We show that the obtained critical hydraulic gradient is close to that defined in classical soil mechanics. To cite this article: M. Mansouri et al., C. R. Mecanique 337 (2009).

A Quick Method for Evaluating the Merits of a Proposed Low Sonic Boom Concept  

NASA Technical Reports Server (NTRS)

The characteristics of a proposed low-boom aircraft concept cannot be adequately assessed unless it is given an extensive, time-consuming, mission-performance, and sonic-boom analyses. So, it would be useful to have a method for performing a quick first-order sonic-boom and mission-range analysis. The evaluation method outlined in this report has the attributes of being both fast and reasonably accurate. It can also be used as a design tool to estimate the sonic-boom ground overpressures, mission range, and beginning-cruise weight of a new low-boom concept during the first stages of preliminary design.

In-situ Mechanistic Study of Cobalt Carbide Nanoparticles by Quick-XAFS  

NASA Astrophysics Data System (ADS)

The emergence of green technology markets such as hybrid/electric vehicles, direct drive wind turbines, and energy storage systems has created an increased demand for permanent magnets. We have explored a new nanostructured cobalt carbide material (NCC), which requires no rare earth elements, employs a simplified synthesis technique that lowers production costs, and has the potential to compete with the highest energy density permanent magnets currently produced. A modified polyol process was used to form the cobalt carbide nanoparticles. The formation mechanism of the Co2C and Co3C systems and their associated high-energy product and large anisotropy are poorly understood. We have utilized in-situ quick-XAFS to examine how variations in temperature, precursor concentration, and cooling rate all affect the formation kinetics of each phase and correlate this with the magnetic properties. The main advantage of Quick-XAFS over that of traditional XAFS is the ability to collect data every second during a reaction. This allows for more quantitative kinetic and mechanistic studies. The identification of the local environment, and in particular, the progression from Co-metal nuclei to the carbide phases is the main goal of this work.

Luteinizing hormone--releasing hormone agonists: a quick reference for prevalence rates of potential adverse effects.  

PubMed

Men with prostate cancer (PCa) frequently undergo androgen deprivation therapy (ADT), typically in the form of a depot injection of luteinizing hormone-releasing hormone agonists (LHRHa). LHRHa are associated with many adverse effects (eg, hot flashes, sexual dysfunction, loss of muscle mass, osteopenia, metabolic syndrome), which drastically impact patient quality of life. This literature review, which includes a comprehensive table documenting prevalence rates, provides a quick reference for health care professionals involved in the care of men undergoing ADT with LHRHa. Primary sources were acquired from PubMed using the search terms "androgen deprivation therapy" and each potentially adverse effect (eg, "androgen deprivation therapy and hot flashes"). Commonly cited review articles were also examined for citations of original studies containing prevalence rates. More than 270 articles were reviewed. In contrast to many existing reviews, rates are cited exclusively from original sources. The prevalence rates, obtained from original sources, suggest that more than half of documented adverse effects are experienced by as many as 40% or more of patients. A critique of the literature is also provided. Although there is a vast literature of both original and review articles on specific adverse effects of LHRHa, the quality of research on prevalence rates for some adverse effects is subpar. Many review articles contain inaccuracies and do not cite original sources. The table of prevalence rates will serve as a quick reference for health care providers when counseling patients and will aid in the development of evidence-based patient education materials.

Photogrammetry and geographic information systems for quick assessment, documentation and analysis of earthquakes  

NASA Astrophysics Data System (ADS)

After a catastrophe like an earthquake, one on the most important problems is to provide shelter and housing for the homeless. To this end, it is necessary to decide if a building is still habitable, or if it is has to be renovated or even torn down. A prerequisite for such decisions is the detailed knowledge about the status of the building. Earlier earthquakes revealed problems in the processes of documenting and analysing the building damage, as they demanded much effort in terms of time and manpower. The main difficulties appeared to be because of the analogue damage assessments which created a great variety of unstructured information that had to be put in a line to allow further analysis. Apart from that, documentation of damage effects was not detailed and could only be carried out on the spot of a disaster. The aim of this study is to make an improvement, using combination of Geographic Information Systems (GIS) as a management and data analysis tool and photogrammetry as a documentation method. Photogrammetric data acquisition is achieved using a CCD camera and the digital photogrammetric software package PICTRAN by Technet. The information system part is the GIS package ArcView by ESRI. The combination of rapid data acquisition and GIS offers a quick assessment of the situation and the possibility of its objective and holistic analysis. This is the prerequisite for a quick initiation of appropriate measures to help people.

Eye Tracking the Face in the Crowd Task: Why Are Angry Faces Found More Quickly?  

PubMed Central

Among a crowd of distractor faces, threatening or angry target faces are identified more quickly and accurately than are nonthreatening or happy target faces, a finding known as the “face in the crowd effect.” Two perceptual explanations of the effect have been proposed: (1) the “target orienting” hypothesis (i.e., threatening targets orient attention more quickly than do nonthreatening targets and (2) the “distractor processing” hypothesis (i.e., nonthreatening distractors paired with a threatening target are processed more efficiently than vice versa, leading to quicker detection of threatening targets). Using a task, with real faces and multiple identities, the current study replicated the face in the crowd effect and then, via eye tracking, found greater support for the target orienting hypothesis. Across both the classical search asymmetry paradigm (i.e., one happy target in a crowd of angry distractors vs. one angry target in a crowd of happy distractors) and the constant distractor paradigm (i.e., one happy target in a crowd of neutral distractors vs. one angry target in a crowd of neutral distractors), fewer distractors were fixated before first fixating angry targets relative to happy targets, with no difference in the processing efficiency of distractors. These results suggest that the face in the crowd effect on this task is supported to a greater degree by attentional patterns associated with properties of target rather those of the crowd.

Quick screening for new flux pinning materials in YBCO films with the combinatorial-PLD method  

NASA Astrophysics Data System (ADS)

An effective way to improve the superconducting properties in REBa 2Cu 3O y (REBCO) films under a magnetic field is to dope artificial pinning centers (APC). The pinning performance depends on the content of the APC materials. Usually, the optimal APC content is explored by preparing films one at a time from the REBCO target using different APC material content, which is an extremely time-consuming process. The combinatorial-PLD (C-PLD) method allowed us to prepare films that continuously changed in composition across a single substrate. In this study, we used the C-PLD method to prepare BaSnO 3 (BSO)-doped YBCO films. The films were deposited on SrTiO 3 substrate using a fourth-harmonic Nd:YAG laser. From the results of the Jc- B curves at 77 K and B// c, the film that contained 3.2 vol.% of BSO exhibited the best pinning performance in this study. We showed that the C-PLD method was efficient for quick screening of the optimal APC content with only one deposition. We also used the C-PLD method to explore new APC materials, and proved that it can quickly evaluate the new APC materials Ba 3Cu 3In 4O 12 and BaTbO 3.

Anatomical study of simple landmarks for guiding the quick access to humeral circumflex arteries  

PubMed Central

Background The posterior and anterior circumflex humeral artery (PCHA and ACHA) are crucial for the blood supply of humeral head. We aimed to identify simple landmarks for guiding the quick access to PCHA and ACHA, which might help to protect the arteries during the surgical management of proximal humeral fractures. Methods Twenty fresh cadavers were dissected to measure the distances from the origins of PCHA and ACHA to the landmarks (the acromion, the coracoid, the infraglenoid tubercle, the midclavicular line) using Vernier calipers. Results The mean distances from the origin of PCHA to the infraglenoid tubercle, the coracoid, the acromion and the midclavicular line were 27.7 mm, 50.2 mm, 68.4 mm and 75.8 mm. The mean distances from the origin of ACHA to the above landmarks were 26.9 mm, 49.2 mm, 67.0 mm and 74.9 mm. Conclusion Our study provided a practical method for the intraoperative identification as well as quick access of PCHA and ACHA based on a series of anatomical measurements.

A novel algorithm for quick and continuous tracing the change of radon concentration in environment.  

PubMed

Several measurements of the radon concentration are performed by RAD7 in the University of South China. We find that 30-40 min is needed for RAD7 for tracing the concentration of the standard radon chamber. There are two reasons. The first is that the sufficient time of air cycle is needed for the radon concentration in internal cell of RAD7 equal to that of the environment; and the second is that the sufficient decay time is needed for the (218)Po concentration in internal cell of RAD7 equal to that of the radon. We used a zeroth order approximation to describe the evolution of the environment radon concentration, and obtained a novel algorithm for quick and continuous tracing the change of radon concentration. The corrected radon concentration obtained through this method is in good agreement with the reference value. This method can be applied to develop and improve the instruments for tracing the change of radon concentration quickly. PMID:21529004

Serologic Diagnosis of Human Taenia solium Cysticercosis by Using Recombinant and Synthetic Antigens in QuickELISA(TM)  

PubMed Central

Diagnosis of Taenia solium cysticercosis is an important component in the control and elimination of cysticercosis and taeniasis. New detection assays using recombinant and synthetic antigens originating from the lentil lectin-purified glycoproteins (LLGPs) of T. solium cysticerci were developed in a QuickELISA™ format. We analyzed a panel of 474 serum samples composed of 108 serum samples from donors with two or more viable cysts, 252 serum samples from persons with other parasitic infections, and 114 serum samples from persons with no documented illnesses. The sensitivities and specificities of T24H QuickELISA™, GP50 QuickELISA™, and Ts18var1 QuickELISA™ were 96.3% and 99.2%, 93.5% and 98.6%, and 89.8% and 96.4%, respectively, for detecting cases with multiple, viable cysts. T24H QuickELISA™ performs best among the three assays, and has sensitivity and specificity values comparable to those of the LLGP enzyme-linked immunosorbent blot. The QuickELISA™ are simple, rapid quantitative methods for detecting antibodies specific for T. solium cysticerci antigens.

The hammer QSD-quick stop device for high speed machining and rubbing  

NASA Technical Reports Server (NTRS)

A quick stop device (QSD) was designed for use in orthogonal machining and rubbing experiments. QSD's are used to obtain chip root samples that are representative of the deformation taking place during dynamic (actual) cutting conditions. These 'frozen' specimens are helpful in examining the plastic deformation that occurs in the regions of compression and shear which form the chip; the secondary shear at the tool-chip interface; and the nose ploughing/flank rubbing action which operates on the newly machined surface. The Hammer QSD employs a shear pin mechanism, broken by a flying hammer, which is traveling at the same velocity as the workpiece. The device has been successfully tested up to 6000 sfpm (30.48 m/sec).

Using liquid superheating energy for a quick estimation of overpressure in BLEVEs and similar explosions.  

PubMed

A method is proposed for the quick estimation of the peak overpressure caused by a Boiling Liquid Expanding Vapor Explosion (BLEVE) or a similar explosion. The method is based on the use of the "superheating energy" (SE), which is the difference between the specific enthalpy of the liquid at the temperature just before the explosion and the specific enthalpy of the liquid at its saturation temperature, at atmospheric pressure. The analysis performed with a set of reference substances showed that in a BLEVE or in similar explosions, the energy converted into overpressure will range between 3.5 and 14% of SE. The comparison of the values thus obtained with experimental data from the literature shows a fairly good agreement. PMID:16766118

Quick testing of batteries in lithium-ion battery packs with impedance-measuring technology  

NASA Astrophysics Data System (ADS)

We discuss a rapid testing of capacity in Li-ion battery packs with impedance-measuring technology to evaluate their capability in mobile phones. Our measurements of the capacity and impedance at 1 kHz for various kinds of battery packs conclusively proved that there is a strong correlation between capacity and impedance. It can be applied even when the pack consists of not only a Li-ion battery but also a Positive Temperature Coefficient (PTC) device and a protection circuit in-series, and this correlation is largely unaffected by the degree of charge. The results we obtained from measuring impedance revealed the possibility of quickly assessing degradation in Li-ion battery packs.

A robust and quick method to validate large scale flood inundation modelling with SAR remote sensing  

NASA Astrophysics Data System (ADS)

With flood frequency likely to increase as a result of altered precipitation patterns triggered by climate change, there is a growing demand for more data and, at the same time, improved flood inundation modeling. The aim is to develop more reliable flood forecasting systems over large scales that account for errors and inconsistencies in observations, modeling, and output. Over the last few decades, there have been major advances in the fields of remote sensing, particularly microwave remote sensing, and flood inundation modeling. At the same time both research communities are attempting to roll out their products on a continental to global scale. In a first attempt to harmonize both research efforts on a very large scale, a two-dimensional flood model has been built for the Niger Inland Delta basin in northwest Africa on a 700 km reach of the Niger River, an area similar to the size of the UK. This scale demands a different approach to traditional 2D model structuring and we have implemented a simplified version of the shallow water equations as developed in [1] and complemented this formulation with a sub-grid structure for simulating flows in a channel much smaller than the actual grid resolution of the model. This joined integration allows to model flood flows across two dimensions with efficient computational speeds but without losing out on channel resolution when moving to coarse model grids. Using gaged daily flows, the model was applied to simulate the wetting and drying of the Inland Delta floodplain for 7 years from 2002 to 2008, taking less than 30 minutes to simulate 365 days at 1 km resolution. In these rather data poor regions of the world and at this type of scale, verification of flood modeling is realistically only feasible with wide swath or global mode remotely sensed imagery. Validation of the Niger model was carried out using sequential global mode SAR images over the period 2006/7. This scale not only requires different types of models and data but also a more robust and quick method to assess model skill than most existing model performance statistics. Existing fit statistics rely most often on fit statistics between a classified remotely sensed image and a model simulation, but this type of assessment becomes quickly impractical at very large scales. Therefore, we propose a quick and robust method to verify model skill based on computing differences between model and SAR image loadings of a principal component analysis for the period of image availability. Although the power of the method to discriminate between models of different hydraulic parameterizations is expected to be relatively limited, our findings show that it may be a quick and objective procedure to inform about model credibility over very large scales by separating out poorly performing models.

Status of the Transformation of the Baker-Numm Camera of San Fernando. Quick Survey Project.  

NASA Astrophysics Data System (ADS)

The current project1 is a collaboration between the Fabra Observatory and the Royal Institute and Observatory of the Spanish Navy in San Fernando(ROA). It aims to transform the ROA's Baker-Nunn camera (BNC), for robotic use with a large format CCD. After its complete refurbishment, the 50cm f/1 BNC will be transferred to a new site located at Catalonia (Spain). There, it will be able to image a 5degx5deg FOV in a single exposure. When working in TDI mode, the entire northern sky will be covered in 4 or 5 nights up to V=20.5. From this huge amount of data, any observational program that could benefit of the large FOV and quick reaction of the camera is potentially to be developed.

Visualization and Logical Binding of Hyperspectral Data Using QuickViz and SAADA  

NASA Astrophysics Data System (ADS)

Next generation integral-field spectrographs (IFS) such as MUSE will record large hyperspectral cubes and thus generate a huge amount of observational and interpretable data. Their visualization remains a problematic and crucial task before any processing. In addition, observation parameters such as variance values may also be associated to each cube and be involved in the scientific interpretation of the data. In this paper, we propose a new software named QuickViz that provides a set of basic and advanced features enabling the exploration of such hyperspectral images with their related observation parameters. This new software is designed in Java as an Aladin plug-in and thus extends its hyperspectral functionalities while managing all the interactions between cubes and extracted spectra. Moreover, the specifications of the SAADA application allowing to automatically generate astronomical relational databases give the ability to easily explore such large data sets with respect to their complex relationships.

Rotary powered device for bone marrow aspiration and biopsy yields excellent specimens quickly and efficiently.  

PubMed

Recently, a new FDA-cleared battery powered bone marrow biopsy system was developed to allow operators access to the bone marrow space quickly and efficiently. A pre-clinical evaluation of the device (OnControl, Vidacare Corporation, San Antonio, TX, USA) on anesthetized pigs was conducted, in addition to a clinical evaluation in hematology clinic patients requiring a bone marrow biopsy. Twenty-six samples were collected from the swine model. No cellular artifact or thermal damage was reported in any of the samples obtained. For the clinical evaluation of the device, 16 patients were recruited. Mean time from needle contact with skin to needle removal was 38.5 +/- 13.94 seconds. No complications were reported. In this study, the manual and powered samples were equivalent in specimen quality. In the patients evaluated, the device was safe, easy to use and the mean procedural time was significantly faster than previously reported with a manual technique. PMID:20404008

Tropical islands quick data gap analysis guided by coral reef geomorphological maps.  

PubMed

A gap analysis is the initial step towards the identification of areas where data are needed. However, often, data coverage cannot be assessed against a reference that objectively guides the identification of both gaps and priority areas for data acquisition. Here, we describe a quick, effective and reproducible spatial data gap analysis approach based on the relationship between location of available metadata and coral reef geomorphological richness. In Solomon Islands, we identified gaps defined by high richness and low biological data coverage. We collected metadata only, to avoid dealing with data ownership, availability, and formats, and to be able to identify gaps in less than two months. This fast method does not replace quantitative and comprehensive gap analysis, but provides effective identification of areas of high natural value and limited knowledge. The method is widely applicable and particularly invaluable for large and complex domains such as the Coral Triangle. PMID:24559737

A simple apparatus for quick qualitative analysis of CR39 nuclear track detectors  

SciTech Connect

Quantifying the ion pits in Columbia Resin 39 (CR39) nuclear track detector from Thomson parabolas is a time consuming and tedious process using conventional microscope based techniques. A simple inventive apparatus for fast screening and qualitative analysis of CR39 detectors has been developed, enabling efficient selection of data for a more detailed analysis. The system consists simply of a green He-Ne laser and a high-resolution digital single-lens reflex camera. The laser illuminates the edge of the CR39 at grazing incidence and couples into the plastic, acting as a light pipe. Subsequently, the laser illuminates all ion tracks on the surface. A high-resolution digital camera is used to photograph the scattered light from the ion tracks, enabling one to quickly determine charge states and energies measured by the Thomson parabola.

Geographic object-based delineation of neighborhoods of Accra, Ghana using QuickBird satellite imagery  

PubMed Central

The objective was to test GEographic Object-based Image Analysis (GEOBIA) techniques for delineating neighborhoods of Accra, Ghana using QuickBird multispectral imagery. Two approaches to aggregating census enumeration areas (EAs) based on image-derived measures of vegetation objects were tested: (1) merging adjacent EAs according to vegetation measures and (2) image segmentation. Both approaches exploit readily available functions within commercial GEOBIA software. Image-derived neighborhood maps were compared to a reference map derived by spatial clustering of slum index values (from census data), to provide a relative assessment of potential map utility. A size-constrained iterative segmentation approach to aggregation was more successful than standard image segmentation or feature merge techniques. The segmentation approaches account for size and shape characteristics, enabling more realistic neighborhood boundaries to be delineated. The percentage of vegetation patches within each EA yielded more realistic delineation of potential neighborhoods than mean vegetation patch size per EA.

Laparoscopic ultrasound for the diagnosis of choledocholithiasis: quick, safe, and effective.  

PubMed

Visualization of the common bile duct during laparoscopic cholecystectomy is frequently required to confirm or exclude choledocholithiasis. Although on-table cholangiogram (OTC) is the traditional imaging technique, laparoscopic ultrasound (LUS) is increasingly deployed for this purpose. We are reporting a 31-month experience with an LUS, starting from the initial set up of the equipment. We retrospectively studied 70 patients who underwent LUS during their laparoscopic cholecystectomy operation over a period of 31 months. Data about preoperative investigation, intraoperative findings, and postoperative outcome were retrospectively collected and analyzed. LUS was found to be quick, safe, and effective in the intraoperative diagnosis of the common bile duct stones. It does not add significantly to the operative time and is inherently safer than intraoperative cholangiogram owing to the fact that it does not involve ionizing radiation. It is also more convenient, as there is no need to wear protective lead to avoid the side effects of ionizing radiation. PMID:24710230

Application of full-waveform inversion to characterize quick-clay landslide site in southwest Sweden.  

NASA Astrophysics Data System (ADS)

Landslides are one of the most commonly occurring natural disasters. Society of Exploration Geophysics (SEG) through its Geoscientists Without Borders (GWB) program sponsored a multidisciplinary project to study quick clay landslides in Sweden. Extensive geophysical survey was conducted over a landslide scar near the river Göta in southwest Sweden. Here, we present the application of full-waveform inversion/tomography (FWT) to seismic profiles that cross the scar. Quick clay could be defined as a clay whose structure collapses completely at remoulding and whose shear strength is thereby reduced almost to zero. Quick clay landslides occur in an unpredictable manner and can affect large areas. A mass of quick clay undergoing sufficient stress (i.e. from excessive rainfall) rapidly liquefies and flows easily even at low slope angles - usually the slope of the bedrock under the clay deposits is more important than the actual slope of the local terrain. Recognition of the geometry and physical properties of clay layers and the underlying bedrock is crucial to understanding the mechanism of a landslide. The sediments in the area have formed thin (~10m) layers of clays and coarse-grain materials. In order to correctly identify them, we need a method that provides high-resolution models, that is why we decided to use FWT. It offers an unprecedented improvement in seismic imaging and thus allows delineating the layering within the sediments. However, FWT not only is demanding in terms of input data, but also offers a challenge when applied in near-surface environment, e.g because of large velocity contrasts. The lines presented here are several hundred meters long, according to the standard checkerboard tests the imaging is accurate up to 40-60 m below the surface. Data was acquired using vertical-component 28-Hz geophones, placed every 2-4 m. The seismic signal is generated either with small amounts of explosives fired in 0.5-1 m deep boreholes, or an accelerated weight-drop, depending on the line. The shot spacing was 2-12 m. We run early-arrival frequency-domain FWT using implementation of Sourbier et al. (2009). Data preprocessing consisted of: trace editing, spectral equalisation, trace muting, 3D-2D correction and time damping. Inversion was performed for frequencies between 27.5 Hz and 43.1 Hz. The starting frequency is relatively high, but little consistent signal was detected below (attributed to the effect of damping of the geophones). The FWT results were validated with a series of extensive procedures: (1) examination of the data fit in the frequency domain; (2) a posteriori source signature estimation; (3) time domain finite difference synthetic modelling; (4) comparison of 1D velocity profiles at the intersection of the seismic lines; (5) comparison with data from other surveys: electrical resistivity tomography, cone penetration tests. We have also performed the pre-stack depth migration (PSDM) of the reflection seismic data using velocity models obtained from FWT. The resulting images show good correspondence with our velocity models, especially in the area of the layering within the sediments and at the boundary with the high velocity granitic bedrock. Flatness of the common-image gathers from PSDM indicates that FWT-derived velocity models are superior to those derived by first-arrival tomography.

Dagik: A Quick Look System of the Geospace Data in KML format  

NASA Astrophysics Data System (ADS)

Dagik (Daily Geospace data in KML) is a quick look plot sharing system using Google Earth as a data browser. It provides daily data lists that contain network links to the KML/KMZ files of various geospace data. KML is a markup language to display data on Google Earth, and KMZ is a compressed file of KML. Users can browse the KML/KMZ files with the following procedures: 1) download "dagik.kml" from Dagik homepage (http://www- step.kugi.kyoto-u.ac.jp/dagik/), and open it with Google Earth, 2) select date, 3) select data type to browse. Dagik is a collection of network links to KML/KMZ files. The daily Dagik files are available since 1957, though they contain only the geomagnetic index data in the early periods. There are three activities of Dagik. The first one is the generation of the daily data lists, the second is to provide several useful tools, such as observatory lists, and the third is to assist researchers to make KML/KMZ data plots. To make the plot browsing easy, there are three rules for Dagik plot format: 1) one file contains one UT day data, 2) use common plot panel size, 3) share the data list. There are three steps to join Dagik as a plot provider: 1) make KML/KMZ files of the data, 2) put the KML/KMZ files on Web, 3) notice Dagik group the URL address and description of the files. The KML/KMZ files will be included in Dagik data list. As of September 2007, quick looks of several geosphace data, such as GPS total electron content data, ionosonde data, magnetometer data, FUV imaging data by a satellite, ground-based airglow data, and satellite footprint data, are available. The system of Dagik is introduced in the presentation. u.ac.jp/dagik/

Global Quick Scan of the Vulnerability of Groundwater systems to Tsunamis  

NASA Astrophysics Data System (ADS)

Fresh groundwater resources in deltaic areas are used for domestic, agricultural and industrial purposes. These resources in the coastal zone are threatened by salinization of the aquifers due to global change (increase of groundwater extraction due to population growth), climate change (including sea level rise), as well as natural disasters such as floods and tsunamis. Studies of how the coastal fresh groundwater resources are affected by the latter phenomena are often done a posteriori, especially the studies related to tsunami effects (e.g. the 2003 Sumatra Tsunami). Then it is often too late to take appropriated measures to counteract the negative effects (e.g. on drinking water supply). These complex studies are time consuming, and need data which might not be available at the time of the disaster when a fast reaction of the water authorities is needed, e.g. to facilitate a quick and easy to access fresh water supply system. In our study we present a Global Quick Scan of the vulnerability of the deltaic fresh groundwater resources to tsunamis. We created a global database including the data needed to generate fast and simple models on the salinization of groundwater systems in the coastal zone. These quantifications give water manager a first approximation of the effects that a tsunami would have on the salinization of the fresh groundwater. The data collected in this database has been used to generate a map showing the areas with coastal groundwater systems vulnerable to tsunami effects, as well as a dataset of 500 2D models representing the physical characteristics of the most frequent coastal groundwater systems in tsunami vulnerable areas. These 2D models simulate the loss in fresh groundwater volume of the system and the characteristic time of a system before it recovers 90% of the fresh groundwater that was available previous to the tsunami event. A similar approach could be adopted for assessing the effect of sea level rise and future increased groundwater extractions on vulnerable coastal groundwater systems worldwide.

Quick look report of acceleration measurements on Mir Space Station during Mir-16  

NASA Technical Reports Server (NTRS)

The NASA Microgravity Science and Applications Division (MSAD) sponsors the Space Acceleration Measurement System (SAMS) to support microgravity science experiments with microgravity acceleration measurements. In the past, SAMS was flown exclusively on the NASA Orbiters. MSAD is currently sponsoring science experiments participating in the Shuttle-Mir Science Program in cooperation with the Russians on the Mir space station. Included in the complement of MSAD experiments and equipment is a SAMS unit installed on the Mir space station. On 25 August 1994, the SAMS unit was launched on a Russia Progress vehicle to the Mir space station. The SAMS unit will support science experiments from the U.S. and Russia in a manner similar to the Orbiter missions by measuring the microgravity environments during the experiment operations. In October 1994, the SAMS unit recorded data on Mir for over fifty-three hours in seven different time periods to survey possible locations for future experiments. This report presents a quick look at the data and the microgravity environment during the time periods in which SAMS data were acquired. The Mir acceleration data were examined to ascertain gross attributes of the data. This report does not present an exhaustive examination of all possible activities due to the short time available to prepare this quick look report and due to the absence of complete timeline information during the SAMS recording time periods. Appendices A, B and C provide plots of the SAMS data for an overview of the microgravity environment at the times that data were recorded. Appendix D describes the procedures to access SAMS data by file transfer protocol (ftp) utilizing the internet. Appendix E contains a user comment sheet.

Implementation of the high-order schemes QUICK and LECUSSO in the COMMIX-1C Program  

SciTech Connect

Multidimensional analysis computer programs based on the finite volume method, such as COMMIX-1C, have been commonly used to simulate thermal-hydraulic phenomena in engineering systems such as nuclear reactors. In COMMIX-1C, the first-order schemes with respect to both space and time are used. In many situations such as flow recirculations and stratifications with steep gradient of velocity and temperature fields, however, high-order difference schemes are necessary for an accurate prediction of the fields. For these reasons, two second-order finite difference numerical schemes, QUICK (Quadratic Upstream Interpolation for Convective Kinematics) and LECUSSO (Local Exact Consistent Upwind Scheme of Second Order), have been implemented in the COMMIX-1C computer code. The formulations were derived for general three-dimensional flows with nonuniform grid sizes. Numerical oscillation analyses for QUICK and LECUSSO were performed. To damp the unphysical oscillations which occur in calculations with high-order schemes at high mesh Reynolds numbers, a new FRAM (Filtering Remedy and Methodology) scheme was developed and implemented. To be consistent with the high-order schemes, the pressure equation and the boundary conditions for all the conservation equations were also modified to be of second order. The new capabilities in the code are listed. Test calculations were performed to validate the implementation of the high-order schemes. They include the test of the one-dimensional nonlinear Burgers equation, two-dimensional scalar transport in two impinging streams, von Karmann vortex shedding, shear driven cavity flow, Couette flow, and circular pipe flow. The calculated results were compared with available data; the agreement is good.

Effects of speed, agility, quickness training method on power performance in elite soccer players.  

PubMed

The purpose of this study was to evaluate the effects of the speed, agility, quickness (SAQ) training method on power performance in soccer players. Soccer players were assigned randomly to 2 groups: experimental group (EG; n = 50) and control group (n = 50). Power performance was assessed by a test of quickness--the 5-m sprint, a test of acceleration--the 10-m sprint, tests of maximal speed--the 20- and the 30-m sprint along with Bosco jump tests--squat jump, countermovement jump (CMJ), maximal CMJ, and continuous jumps performed with legs extended. The initial testing procedure took place at the beginning of the in-season period. The 8-week specific SAQ training program was implemented after which final testing took place. The results of the 2-way analysis of variance indicated that the EG improved significantly (p < 0.05) in 5-m (1.43 vs. 1.39 seconds) and in 10-m (2.15 vs. 2.07 seconds) sprints, and they also improved their jumping performance in countermovement (44.04 vs. 4.48 cm) and continuous jumps (41.08 vs. 41.39 cm) performed with legs extended (p < 0.05). The SAQ training program appears to be an effective way of improving some segments of power performance in young soccer players during the in-season period. Soccer coaches could use this information in the process of planning in-season training. Without proper planning of the SAQ training, soccer players will most likely be confronted with decrease in power performance during in-season period. PMID:21522073

Final phase I report and phase II work plan : QuickSite{reg_sign} investigation, Centralia, Kansas.  

SciTech Connect

The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), formerly operated a grain storage facility approximately 1,100 ft north of Centralia (Figure 1.2). The CCC/USDA operated this facility from 1949 until 1971. None of the CCC/USDA structures remain. Two additional grain storage facilities currently exist in and near Centralia: the Nemaha County Co-op, approximately 4,000 ft south of the former CCC/USDA facility, and a private grain storage facility near the Don Morris residence, 3,500 ft north of the former CCC/USDA facility. Prior to 1986, commercial grain fumigants containing carbon tetrachloride were commonly used by the CCC/USDA and the grain storage industry to preserve grain. In April 1998, the Kansas Department of Health and Environment (KDHE) sampled the domestic well at the Don Morris residence near Centralia (Figure 1.2) as part of the CCC/USDA Private Well Sampling Program, which was initiated to determine whether carbon tetrachloride was present in domestic wells located near former CCC/USDA grain storage facilities in Kansas. Carbon tetrachloride was detected in the Morris well at 19.3 mg/L and confirmed at 25.4 mg/L, both concentrations above the maximum contaminant level (MCL) of 5 mg/L for carbon tetrachloride in drinking water. On the basis of the detection of carbon tetrachloride in the Morris well, the KDHE in August-September 1998 conducted preliminary investigations at the former CCC/USDA facility. For the details of previous investigations in the area and a summary of their findings, see the QuickSite{reg_sign} Phase I Work Plan for Centralia (Argonne 2002a). Because the KDHE found carbon tetrachloride at the former CCC/USDA facility at Centralia that might, in part, be linked to historical use of carbon tetrachloride-based grain fumigants at the facility, the CCC/USDA is conducting an environmental site investigation at Centralia. However, the KDHE established in 1998 that the probable groundwater flow direction at the former CCC/USDA facility is not toward the Morris well, and thus the former facility is not responsible for the carbon tetrachloride measured in that well. The town of Centralia and all residents near the former CCC/USDA facility currently obtain their water from Rural Water District No.3 (RWD 3). Therefore, these local residents are not drinking and using contaminated groundwater. The investigation at Centralia is being performed by the Environmental Research Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by the University of Chicago for the U.S. Department of Energy (DOE). The CCC/USDA has entered into an interagency agreement with DOE, under which Argonne provides technical assistance to the CCC/USDA with environmental site characterization and remediation at its former grain storage facilities. At these facilities, Argonne is applying its QuickSite environmental site characterization methodology. QuickSite is Argonne's proprietary implementation system for the expedited site characterization (ESC) process. Argonne's Environmental Research Division developed the ESC process to optimize preremedial site characterization work at hazardous waste sites by obtaining and then applying a thorough understanding of a site's geology, hydrogeology, and hydrogeochemistry (e.g., Burton 1994). This approach is fundamental to successful site characterization because the geology and hydrogeology of a site largely govern the mobility and fate of contaminants there. Argonne's ESC process has been used successfully at a number of former CCC/USDA facilities in Kansas and Nebraska and has been adopted by the American Society for Testing and Materials (ASTM 1998) as standard practice for environmental site characterization. This report documents the findings of the Phase I activities at Centralia. Section 1 provides a brief history of the area and the QuickSite process, a summary of the geologic/hydrogeologic model, objectives of the Phase I investigation, and a brief description of the sections cont

Quick biochemical markers for assessment of quality control of intraoperative cell salvage: a prospective observational study  

PubMed Central

Background Intraoperative Cell Salvage (ICS), hereby referred to ‘mechanical red cell salvage’, has been widely used in adult elective major surgeries to reduce requirement for homologous red blood cell transfusion and its associated complications. However, amount of free haemoglobin (fHb) from ICS has been shown related to incidence of renal failure. fHb is the most important indicator of quality control of cell salvaged blood, thus monitoring the fHb concentration is imperative to minimise renal injury. However, currently there has been lacking quick biochemical markers to monitor the levels of fHb during ICS. The aim of this study was to screen quick biochemical markers for evaluating the amount of fHb during use of intraoperative cell salvage. Methods Twenty patients undergoing elective cardiovascular surgery were enrolled. Blood was collected and processed using a Fresenius continuous auto-transfusion system device. The concentration of fHb, albumin (Alb), and calcium (Ca) in three washing modes were measured, and their clearance rates were calculated. The correlations among the clearances and concentrations of fHb, albumin, and calcium were analysed. Results In three washing modes, concentrations of albumin and calcium are significantly associated with amount of fHb:fHb(g/L) = 0.111Alb(g/L) –0.108, R = 0.638, p?=?0.000; fHb(g/L) = 1.721Ca(mmol/L) +0.091, R = 0.514, p?=?0.000. Furthermore, the clearance rates of albumin and calcium significantly predict clearance of fHb, CRfHb?=?0.310CRALB?+?0.686, R = 0.753, p?=?0.000, CRfHb?=?0.073 CR Ca?+?0.913, R = 0.497, p?=?0.000. Conclusions In clinic practice, clearance rates of albumin, or calcium can be used to evaluate the quality of salvaged blood, fHb. Bed-side measurement of calcium could offer a more feasible means for clinicians to undertake a real-time assessment of fHb.

This manual augments the detailed manual of the GW-BASIC version of the LTC code for an application in QuickBASIC. As most of the GW-BASIC coding of this program for ``LMR Transient Calculations`` is compatible with QuickBASIC, this manual pertains primarily to the required changes, such as the handling of input and output. The considerable reduction in computation time achieved by this conversion is demonstrated for two sample problems, using a variety of hardware and execution options. The revised code is listed. Although the severe storage limitations of GW-BASIC no longer apply, the LOF transient path has not been completed in this QuickBASIC code. Its advantages are thus primarily in the much faster running time for TOP and LOHS transients. For the fastest PC hardware (486) and execution option the computation time is reduced by a factor of 124 compared to GW-BASIC on a 386/20.

Farm Mapping to Assist, Protect, and Prepare Emergency Responders: Farm MAPPER.  

PubMed

ABSTRACT Responders such as firefighters and emergency medical technicians who respond to farm emergencies often face complex and unknown environments. They may encounter hazards such as fuels, solvents, pesticides, caustics, and exploding gas storage cylinders. Responders may be unaware of dirt roads within the farm that can expedite their arrival at critical sites or snow-covered manure pits that act as hidden hazards. A response to a farm, unless guided by someone familiar with the operation, may present a risk to responders and post a challenge in locating the victim. This project explored the use of a Web-based farm-mapping application optimized for tablets and accessible via easily accessible on-site matrix barcodes, or quick response codes (QR codes), to provide emergency responders with hazard and resource information to agricultural operations. Secured portals were developed for both farmers and responders, allowing both parties to populate and customize farm maps with icons. Data were stored online and linked to QR codes attached to mailbox posts where emergency responders may read them with a mobile device. Mock responses were conducted on dairy farms to test QR code linking efficacy, Web site security, and field usability. Findings from farmer usability tests showed willingness to enter data as well as ease of Web site navigation and data entry even with farmers who had limited computer knowledge. Usability tests with emergency responders showed ease of QR code connectivity to the farm maps and ease of Web site navigation. Further research is needed to improve data security as well as assess the program's applicability to nonfarm environments and integration with existing emergency response systems. The next phases of this project will expand the program for regional and national use, develop QR code-linked, Web-based extrication guidance for farm machinery for victim entrapment rescue, and create QR code-linked online training videos and materials for limited English proficient immigrant farm workers.

In this paper, estimating the soil salinity of Pingluo County, China by a partial least squares regression (PLSR) predictive model was carried out using QuickBird data and soil reflectance spectra. At first, a relationship between the sensitive bands of soil salinity acquired from measured reflectance spectra and the spectral coverage of seven commonly used optical sensors was analyzed. Secondly, the potentiality of QuickBird data in estimating soil salinity by analyzing the correlations between the measured reflectance spectra and reflectance spectra derived from QuickBird data and analyzing the contributions of each band of QuickBird data to soil salinity estimation Finally, a PLSR predictive model of soil salinity was developed using reflectance spectra from QuickBird data and eight spectral indices derived from QuickBird data. The results indicated that the sensitive bands covered several bands of each optical sensor and these sensors can be used for soil salinity estimation. The result of estimation model showed that an accurate prediction of soil salinity can be made based on the PLSR method (R2 = 0.992, RMSE = 0.195). The PLSR model's performance was better than that of the stepwise multiple regression (SMR) method. The results also indicated that using spectral indices such as intensity within spectral bands (Int1, Int2), soil salinity indices (SI1, SI2, SI3), the brightness index (BI), the normalized difference vegetation index (NDVI) and the ratio vegetation index (RVI) as independent model variables can help to increase the accuracy of soil salinity mapping. The NDVI and RVI can help to reduce the influences of vegetation cover and soil moisture on prediction accuracy. The method developed in this paper can be applied in other arid and semi-arid areas, such as western China.

Substitution of valine for glycine-558 in the congenital dysthrombin thrombin Quick II alters primary substrate specificity  

SciTech Connect

Thrombin Quick II is one of two dysfunctional forms of thrombin derived from the previously described congenital dysprothrombin prothrombin Quick. Thrombin Quick II does not clot fibrinogen, hydrolyze p-nitroanilide substrates of thrombin, or bind N{sup 2}-(5-(dimethylamino)naphthalene-1-sulfonyl)arginine N,N-(3-ethyl-1,5-pentanediyl)amide, a high-affinity competitive inhibitor of thrombin. To determine the structural alteration in thrombin Quick II, the reduced, carboxymethylated protein was hydrolyzed by a lysyl endopeptidase. A peptide not present in a parallel thrombin hydrolysate was identified by reverse-phase chromatography. This Gly residue, which is highly conserved in the chymotrypsin family of serine proteases, forms part of the substrate binding pocket for bulky aromatic and basic side chains in chymotrypsin and trypsin, respectively. However, in porcine elastase 1, the corresponding residue is threonine. Consistent with the identified structural alteration, thrombin Quick II incorporates ({sup 3}H)diisopropyl fluorophosphate stoichiometrically and hydrolyzes the elastase substrate succinyl-Ala-Ala-Pro-Leu-p-nitroanilide with a relative k{sub cat}/K{sub M} of 0.14 when compared to thrombin. This results from a 3-fold increase in K{sub M} and a 2.5-fold decrease in k{sub cat} for thrombin Quick II when compared to thrombin acting on the same substrate. These results and those of other investigators studying mutant trypsins support the conclusion that the catalytic activity of serine proteases is very sensitive to structural alterations in the primary substrate binding pocket.

Mechanism of brush border contractility studied by the quick-freeze, deep-etch method  

PubMed Central

We have analyzed terminal web contraction in sheets of glycerinated chicken small intestine epithelium and in isolated intestinal brush borders using a quick-freeze, deep-etch, rotary shadow replication technique. In the presence of Mg-ATP at 37 degrees C, the terminal web region of each cell in the glycerinated sheet and of each isolated brush border became severely constricted at the level of its zonula adherens (ZA). Consequently, the individual brush borders rounded up, splaying out their microvilli in fanlike patterns. The most prominent ultrastructural changes that occurred during terminal web contraction were a dramatic decrease in the diameter of the circumferential ring composed of a bundle of 8-9-nm filaments adjacent to the zonula adherens and a decrease in the number of cross-linkers between the microvillus rootlets. Microvilli were not retracted into the terminal web. We have used myosin S1 decoration to demonstrate that most of the circumferential bundle filaments are actin and that the actin filaments are arranged in the bundle with mixed polarity. Some filaments within the bundle did not decorate with myosin S1 and had tiny projections that appeared to be attached to adjacent actin filaments. Because of their morphology and immunofluorescent localization of myosin within this region of the terminal web, we propose that these undecorated filaments are myosin. From these results, we conclude that brush border contraction is caused primarily by an active sliding of actin and myosin filaments within the circumferential bundle of filaments associated with the ZA.

Quick Synthesis of Carbon Nitride Films by New DC Hollow Cathode Plasma Sputtering Deposition Technique  

NASA Astrophysics Data System (ADS)

High N content of carbon nitride films are quickly deposited onto Si (100) substrates at room temperature by using DC hollow cathode plasma sputtering deposition technique. The deposition rate is up to 283 nm/min at the bias voltage of 400 V. The properties of the films are characterized by using XPS, Raman (scattering) and Fourier transformation infrared (FTIR) spectroscopy. Experiments results provide direct evidences that the structures of CN films can be controlled by regulating bias voltages. The maximum sp3C-N concentration up to 0.73 is obtained. Raman data is used to confirm XPS results. FTIR of the films clearly show C-N and C=N components (1000-1800 cm-1) together with a tiny peak C?N (2181 cm-1). By reducing particle energy and substrate temperature, we have succeeded in suppressing the mechanisms of losing N-contain species during deposition, and achieved a large amount of sp3 bonds of CN films.

Fast k-NNG Construction with GPU-Based Quick Multi-Select.  

PubMed

In this paper, we describe a new brute force algorithm for building the [Formula: see text]-Nearest Neighbor Graph (k-NNG). The k-NNG algorithm has many applications in areas such as machine learning, bio-informatics, and clustering analysis. While there are very efficient algorithms for data of low dimensions, for high dimensional data the brute force search is the best algorithm. There are two main parts to the algorithm: the first part is finding the distances between the input vectors, which may be formulated as a matrix multiplication problem; the second is the selection of the k-NNs for each of the query vectors. For the second part, we describe a novel graphics processing unit (GPU)-based multi-select algorithm based on quick sort. Our optimization makes clever use of warp voting functions available on the latest GPUs along with user-controlled cache. Benchmarks show significant improvement over state-of-the-art implementations of the k-NN search on GPUs. PMID:24809341

Detection of urban expansion in an urban-rural landscape with multitemporal QuickBird images  

PubMed Central

Accurately detecting urban expansion with remote sensing techniques is a challenge due to the complexity of urban landscapes. This paper explored methods for detecting urban expansion with multitemporal QuickBird images in Lucas do Rio Verde, Mato Grosso, Brazil. Different techniques, including image differencing, principal component analysis (PCA), and comparison of classified impervious surface images with the matched filtering method, were used to examine urbanization detection. An impervious surface image classified with the hybrid method was used to modify the urbanization detection results. As a comparison, the original multispectral image and segmentation-based mean-spectral images were used during the detection of urbanization. This research indicates that the comparison of classified impervious surface images with matched filtering method provides the best change detection performance, followed by the image differencing method based on segmentation-based mean spectral images. The PCA is not a good method for urban change detection in this study. Shadows and high spectral variation within the impervious surfaces represent major challenges to the detection of urban expansion when high spatial resolution images are used.

GeoEye vs. QuickBird: operational potentialities, limits, and integration for fast map production  

NASA Astrophysics Data System (ADS)

Very High Resolution Satellite (VHRS) images have already demonstrated their great potentialities both for the generation of satellite orthoimages and for map production and updating at the middle scale (1:10000 - 1:5000). Nevertheless a big research effort has still to be done in order to investigate how different data with similar features can be integrated to improve the final result and especially to overcome the objective difficulty, for a common customer, of getting stereopairs from a single sensor. In this work a Geo GeoEye image and an Orthoready QuickBird one covering about 120 Km2 in the region of Tera (Niger), are considered to determine how successfully they can be integrated to exploit the maximum of resident information required to describe as better as possible the test area. A comparative process was employed to determine the planimetric positional difference affecting the original acquired images, the orthoimages obtained through a Rational Function Model (RFM) approach based on the released RPC (Rational Polynomial Coefficients) and a "rigorous" multi-sensor bundle adjustment performing the simultaneous orientation of both the images in a single block.

Ultrastructural study of normal rat glomeruli by the quick-freezing and deep-etching method.  

PubMed

The ultrastructural features of isolated normal rat glomeruli were investigated using a new splitting technique and the quick-freezing and deep-etching (QF-DE) method. Examinations were also made of in vivo normal rat glomeruli by the QF-DE method to visualize the glomeruli under near natural conditions. Freeze-fractured capillary loops were observed from the capillary lumen or the urinary space. Foot processes were found to be freeze-fractured horizontally, obliquely or vertically to the glomerular basement membrane (GBM), and a glomerular slit diaphragm, which consisted of sheet-like, ladder-like and zipper-like substructures, was clearly identified. The GBM was classified into three zones, which might correspond to those seen in ultrathin sections, including the lamina densa and laminae rarae externa and interna. The lamina densa was composed of a meshwork filled with fine particles, which might represent products of insoluble proteins. In the laminae rarae, filamentous structures consisting of irregular networks could be observed connecting glomerular endothelial or epithelial cells with the lamina densa. Furthermore, the above findings were obtained from investigations at various consecutive levels of freeze-fractured capillary loops from various angles. The three-dimensional ultrastructure of the glomeruli could be demonstrated at high resolution by the QF-DE method. PMID:1774840

Quick X-Ray Reflectometry in the Simultaneous Multiple Angle-Wavelength Dispersive Mode  

NASA Astrophysics Data System (ADS)

The whole profile of the specular X-ray reflectivity curve was simultaneously and quickly measured with no need to rotate the specimen, the detector or the monochromator crystal. A white synchrotron beam from a bending magnet source is incident on a bent-twisted silicon (111) crystal polychromator that produces a convergent X-ray beam with a continuously varying wavelength (energy) and glancing angle to the specimen surface. This convergent X-ray beam was specularly reflected in the vertical direction by the specimen placed at the focus. The normalized spatial distribution across the beam direction of the reflected beam represents a specular X-ray reflectivity curve because each position along the line recorded on the two dimensional detector surface corresponds to a different momentum transfer. Reflectivity curves from a (001) silicon wafer, a nickel thin film on a silicon substrate, and a water surface were measured with data collection times of 0.001-100 s, 0.01-100 s, and 1.0-1000 s, respectively. The simultaneously covered momentum transfer range was 0.03-0.52 Å-1 for solid specimens and 0-0.41 Å-1 for liquid specimen.

[Quick determination of formaldehyde remnant in the pharmic intermediates by homemade microspectrometer].  

PubMed

The rapid and real-time analytical system based on photometrical methodology of a homemade holographic flat field concave grating integrated microspectrometer was established, which was applied to detect the remnant formaldehyde in the intermediate of ranitidine synthesis. Based on the chromogenic reaction of formaldehyde with MBTH and NH4Fe (SO4)2 in acid medium, the methodology of formaldehyde detection was developed. Furthermore, factors affecting the chromogenic reaction were optimized in details. Under the optimized conditions, a good linear relationship in the range of 0.04-0.20 microg x mL(-1) (r = 0.993 8) was obtained and the lowest detection limit achieved 0.04 microg x mL(-1). In order to demonstrate the methodology and reliability of the microspectrometer analytical system, comparative experiments were carried on among the homemade microspectrometer, SHIMADZU UV-2550 spectrophotometer and U.S.A. Ocean Optic HR2000 Microspectrometer. The F-test was employed to check the reliability and efficiency of the proposed methodology. No significant difference was shown among them. The experimental results showed that the set up analytical system could satisfy the needs of quick and real-time detection in practical applications for experimental analysis, industrial monitoring and medicinal diagnosis.

Detecting Slums from Quick Bird Data in Pune Using AN Object Oriented Approach  

NASA Astrophysics Data System (ADS)

We have been witnessing a gradual and steady transformation from a pre dominantly rural society to an urban society in India and by 2030, it will have more people living in urban than rural areas. Slums formed an integral part of Indian urbanisation as most of the Indian cities lack in basic needs of an acceptable life. Many efforts are being taken to improve their conditions. To carry out slum renewal programs and monitor its implementation, slum settlements should be recorded to obtain an adequate spatial data base. This can be only achieved through the analysis of remote sensing data with very high spatial resolution. Regarding the occurrences of settlement areas in the remote sensing data pixel-based approach on a high resolution image is unable to represent the heterogeneity of complex urban environments. Hence there is a need for sophisticated method and data for slum analysis. An attempt has been made to detect and discriminate the slums of Pune city by describing typical characteristics of these settlements, by using eCognition software from quick bird data on the basis of object oriented approach. Based on multi resolution segmentation, initial objects were created and further depend on texture, geometry and contextual characteristics of the image objects, they were classified into slums and non-slums. The developed rule base allowed the description of knowledge about phenomena clearly and easily using fuzzy membership functions and the described knowledge stored in the classification rule base led to the best classification with more than 80% accuracy.

The Virtual Space Physics Observatory: Quick access to Data and Tools  

NASA Astrophysics Data System (ADS)

The Virtual Space Physics Observatory (VSPO; http://vspo.gsfc.nasa.gov) has grown to provide a way to find and access about 375 data products and services from over 100 spacecraft/observatories in space and solar physics. The datasets are mainly chosen to be the most requested, and include most of the publicly available data products from operating NASA Heliophysics spacecraft as well as from solar observatories measuring across the frequency spectrum. Service links include a "quick orbits" page that uses SSCWeb Web Services to provide a rapid answer to questions such as "What spacecraft were in orbit in July1992?" and "Where were Geotail, Cluster, and Polar on 2 June 2001?" These queries are linked back to the data search page. The VSPO interface provides many ways of looking for data based on terms used in a registry of resources using the SPASE Data Model that will be the standard for Heliophysics Virtual Observatories. VSPO itself is accessible via an API that allows other applications to use it as a Web Service; this has been implemented in one instance using the ViSBARD visualization program. The VSPO will become part of the Space Physics Data Facility, and will continue to expand its access to data. A challenge for all VOs will be to provide uniform access to data at the variable level, and we will be addressing this question in a number of ways.

Application and evaluation of ISVR method in QuickBird image fusion  

NASA Astrophysics Data System (ADS)

QuickBird satellite images are widely used in many fields, and applications have put forward high requirements for the integration of the spatial information and spectral information of the imagery. A fusion method for high resolution remote sensing images based on ISVR is identified in this study. The core principle of ISVS is taking the advantage of radicalization targeting to remove the effect of different gain and error of satellites' sensors. Transformed from DN to radiance, the multi-spectral image's energy is used to simulate the panchromatic band. The linear regression analysis is carried through the simulation process to find a new synthetically panchromatic image, which is highly linearly correlated to the original panchromatic image. In order to evaluate, test and compare the algorithm results, this paper used ISVR and other two different fusion methods to give a comparative study of the spatial information and spectral information, taking the average gradient and the correlation coefficient as an indicator. Experiments showed that this method could significantly improve the quality of fused image, especially in preserving spectral information, to maximize the spectral information of original multispectral images, while maintaining abundant spatial information.

Quick estimation of heats of detonation of aromatic energetic compounds from structural parameters.  

PubMed

In this paper, a simple procedure is introduced for a quick and reliable estimation of detonation heats of aromatic energetic compounds without considering heats of formation of energetic compounds. This method does not use any experimental or computed data of energetic materials. The methodology assumes that the heat of detonation of an energetic compound with composition of C(a)H(b)N(c)O(d) can be obtained from the number of nitrogens, ratios of oxygen to carbon and hydrogen to oxygen as well as the contribution of some specific functional groups. There is no need to use any assumed decomposition products to calculate heats of detonation for energetic compounds. Predicted heats of detonation of pure energetic compounds with the product H(2)O in the liquid state for 31 aromatic energetic compounds have a root mean square (rms) of deviation of 0.32 kJ/g from experiment. The new method gives good results with respect to two empirical methods which use measured heats of formation of explosives with two sets of decomposition gases. PMID:17074439

Quick-freezing of cultured cardiac cells in situ with special attention to the mitochondrial ultrastructure.  

PubMed

A new method has been developed which allows quick-freezing in situ of primary, cardiac cell cultures grown to confluence on gas-permeable membranes (Petriperm dishes). Small pieces of the growth substratum, with rhythmically beating myocardial cells, were slam-frozen, without cryoprotectants, against the surface of a helium-cooled copper block at approximately 16 K. The quality of the cellular cryopreservation, as judged by ultrastructural criteria, was studied in freeze-substituted specimens processed for transmission electron microscopy. The ultrastructure of cryofixed cardiac cells was compared with that of unfrozen, chemically fixed samples. The severity of cryodistortions increased progressively with increasing distance from the point of first impact. Of particular interest were the dramatic alterations of the mitochondrial ultrastructure. The concept that the reticular and the outer mitochondrial membranes are intimately and strongly associated was clearly demonstrated. Optimally frozen material revealed cryopreserved ultrastructure of high quality. The method described appears to offer an ideal model system for correlating the information gained by phase-contrast microscopy of living cell cultures with the ultrastructure of the same samples fixed in situ by chemical or physical techniques. Cryofixation would be particularly useful for studying dynamic cellular processes associated with physiological and pathophysiological conditions, e.g. metabolic inhibition, anoxia and substrate deprivation.

Quick-look eye-safety assessment for the short range lidar  

SciTech Connect

This is a quick-look eye-safety assessment for the Short Range (SR) lidar, a system under development for standoff biological aerosol detection in the outdoor environment. The ground-vehicle-mounted SR lidar system will scan a sector of the nearby atmosphere with a repetitively pulsed, multiple-wavelength, UV/IR laser beam. This laser is not intrinsically eye-safe, and hence the SR lidar system requires a protection system to minimize the risk of eye exposures above the ANSI-standard maximum permissible exposure within a nominal hazard zone. The nominal ocular hazard distance for the UV/IR laser itself was calculated to be 6 km. The protection system, which will include a scan-stop detector and a laser beam path interrogator, currently is conceptual only. Until the complete protection system is designed, evaluated, and tested, and a more detailed safety assessment has been performed, the eye-safety issue for the SR lidar system cannot be resolved.

The QuickReduce Data Reduction Pipeline for the WIYN One Degree Imager  

NASA Astrophysics Data System (ADS)

Optimizing one's observing strategy while at the telescope relies on knowing the current observing conditions and the obtained data quality. In particular the latter is not straight forward with current wide-field imagers, such as the WIYN One Degree Imager (ODI), currently consisting of 13 detectors, each of them read out in 64 independent cells. Here we present a fast data reduction software for ODI, optimized for a first data inspection during acquisition at the the telescope, but capable enough for science-quality data reductions. The pipeline is coded in pure python with minimal additional requirements. It is installed on the ODI observer's interface and publicly available from the author's webpage. It performs all basic reduction steps as well as more advanced corrections for pupil-ghost removal, fringe correction and masking of persistent pixels. Additional capabilities include adding an accurate astrometric WCS solution based on the 2MASS reference system as well as photometric zeropoint calibration for frames covered by the SDSS foot-print. The pipeline makes use of multiple CPU-cores wherever possible, resulting in an execution time of only a few seconds per frame. As such this QuickReduce pipeline offers the ODI observer a convenient way to closely monitor data quality, a necessity to optimize the observing strategy during the night.

Quick Screen to Detect Current and Future Substance Use Disorder in Female Adolescents  

PubMed Central

Background Prevention of substance use disorder (SUD) is impeded by the large number, complexity and idiosyncratic configuration of etiological factors. Effective prevention of SUD is feasible however when intervention resources are prioritized to individuals who are objectively determined as high risk and tailored to their specific characteristics and circumstances. Objective This study had the aim of developing a rapid accurate screening instrument for determining current presence of and future risk for SUD. Methods The sample consisted of 182 girls recruited when they were 10–12 years of age and tracked to 22 years of age. From a large item pool the Drug Use Screening Inventory Quick Screen for Females (DQS-F) was derived consisting of the Substance Involvement Index and the Problem Severity Index. Results The DQS for Females (DQS-F) has high sensitivity for identifying girls who currently qualify for SUD diagnosis. Furthermore, accuracy of predicting future SUD with the DQS-F is in the good range at age 16 and in the very good range at age 19. Conclusions Requiring only three minutes for administration on the Web the DQS-F is an efficient method for identifying girls requiring thorough assessment prior to implementing individualized intervention

Total electron content (TEC) measured simultaneously using Global Positioning System (GPS) ionospheric monitors installed at some locations in Nigeria during the year 2011 (Rz = 55.7) was used to study the diurnal, seasonal, and annual TEC variations. The TEC exhibits daytime maximum, seasonal variation and semiannual variations. Measured TEC were compared with those predicted by the improved versions of the International Reference Ionosphere (IRI) and NeQuick models. The models followed the diurnal and seasonal variation patterns of the observed values of TEC. However, IRI model produced better estimates of TEC than NeQuick at all locations.

Quick recovery of orientation after 100 Hz magnetic seizure therapy (MST) for major depressive disorder  

PubMed Central

Introduction Magnetic seizure therapy (MST), in which seizures are elicited with a high-frequency magnetic field, is under development as a new treatment for major depressive disorder. Its use may be justified if it produces the antidepressant effects of ECT, coupled with limited cognitive side effects. This pilot study reports shortened recovery times after MST compared with ECT as a preliminary step to evaluate the usefulness of a new 100Hz MST device. Methods We induced seizures with 100Hz magnetic transcranial stimulation in eleven patients with major depressive disorder during one session of a regular course of ECT. Recovery times after these MST and ECT induced seizures were compared. Results Seizures could be elicited in ten of the eleven patients. Stimulation over the vertex produced tonic-clonic activity on nine out of eleven occasions. Stimulation over the prefrontal midpoint elicited seizures on three out of seven occasions. The mean duration of magnetically induced seizures was 31.3 sec, ranging from 10-86 sec. All patients had an exceptionally quick recovery of orientation: mean of 7 min 12 sec (SD = 2 min 7 sec, range 4 min 20 sec – 9 min 41 sec). The recovery times were on average 15 min 35 sec shorter with MST than with ECT in the same patients (paired-samples t-test: p = 0.00009). Patients reported feeling less confused after MST. Side effects were confined to myoclonic movements, associated with the use of etomidate. Conclusions The new 100 Hz magnetic stimulator elicits seizures in the majority of patients when administered over the vertex. MST was associated with shorter recovery times and less confusion following treatment. Subsequent work will be required to assess the safety and effectiveness of MST in the treatment of depression.

Searching the Sloan Digital Sky Survey the Quick and Easy Way  

NASA Astrophysics Data System (ADS)

For more than four years, the SkyServer web site (http://skyserver.sdss.org) has made the complete database of the Sloan Digital Sky Survey available to the public, with lesson plans for teachers from elementary school through college. One of the most powerful features of the site is the ability to search the database, returning thousands or millions of matches for a variety of questions. For example, a search for galaxies with green-wavelength (g) magnitudes brighter than 18 and g-r colors less than 2 returns 498,874 galaxies. However, to search the SDSS in this way, users have always needed to know SQL (Structured Query Language), a programming language used to search databases throughout the academic and business world. Learning SQL is difficult, and many teachers have found that learning the language takes more time than they are able to devote. We have created SkyServer tools to make searching the SDSS database much easier. These new tools will allow users to select options from a series of menus, building up a SQL query step-by-step in an intuitive way. For example, the galaxy query described above could be built by selecting "galaxies," then "g < 18," then "g-r < 2." Our philosophy has been that these tools should allow users to jump right in to searching the database, but they should also teach SQL, allowing users to write more sophisticated searches on their own relatively quickly. In this talk, we will demonstrate some of these new tools.

Development of quick and accurate automatic hypocenter location system for the earthquake alarm  

NASA Astrophysics Data System (ADS)

Most earthquake damage occurs after arrival of the S wave, whose amplitude is about five times larger than the P wave. Because the P wave travels faster than the S wave, the interval between their arrival times creates an opportunity to activate an earthquake alarm and take preemptive safety measures. We developed an automatic system which transmits the earthquake shaking intensity before S wave arrival. Since the alarm system is used to control transportation, industry, business, etc, at a time of a large earthquake occurrence, false alarms cost huge. We solved the technical difficulty of determining earthquake parameters very quickly and without errors, by developing a novel method using not only P wave arrival times but also time data of P wave not yet arrived. We also developed filters which can distinguish seismic signal from large amplitude noise generated by many kinds of reasons. The system can eliminate extraneous arrival-time readings during the process of hypocenter location by checking automatically measured readings, P wave not yet arrived data, and their station distribution. We use waveform data of Hi-net (High Sensitivity Seismograph Network Japan, National Research Institute for Earth Science and Disaster Prevention) composed of ca. 700 very high quality stations covering whole Japan with space density of 20 to 30 km. All seismometers are installed on observation wells deeper than 100m. Our system can locate precise hypocenters for 97 % felt events occurring in and near Japan Islands within a few seconds and transmits earthquake alarm information before most of seismic energy has arrived even to the station closest to the hypocenter. We are broadcasting earthquake alarm information for all destructive earthquakes by using the satellite system developed by ERI (Earthquake Research Institute, Univ. of Tokyo), and hoping to promote the development of many kinds of automatic control systems which stop cars, factories, etc to protect people from earthquake damage.

A proposal of utilization of penetrators as a quick deployment system of instruments in an emergency  

NASA Astrophysics Data System (ADS)

In the 2011 Tohoku Great earthquake, towns and lifelines were completely destroyed mainly by the mega Tsunami-waves induced by the earthquake. Many people were killed and injured. In addition to the direct destroy of seismic stations, cut-off of electronic power and communication lines made a seismic measurement impossible after the earthquake. The data of seismicity near the destroyed area had been lacked. The quake also destroyed the Fukushima atomic plant that emitted a lot of radioactive elements such as iodine 131 and cesium 137 around the plant. The area of the inside of a circle with a distance of 20 km from the plant has been kept out soon after the failure, where people exactly desire to know what happens and exact quantities of some geophysical and geochemical measurements. In this presentation, we propose a penetrator system as an efficient way to deploy measurement stations for an emergent event such as the 2011 Tohoku Great earthquake. The penetrator technique has been developed in the former Japanese lunar exploration project LUNAR-A and after the cancelation of the project. The penetrator was planned to carry seismic sensors and heat flow probes into the surface regolith of the moon in the project. It collides with the lunar surface with a speed of 300 m/s. We have established a technique to survive the sensors in the penetrator throughout the hard landing. The technique is of course applicable for terrestrial measurements. A measurement in an emergent area is suitable for the penetrator system. Using penetrators, we can deploy sensors in a kept-out area by throwing them into target sites from a flying boat. Penetrators can be used to establish communication lines in a damaged area by carrying a translator of radio waves. Because of the easiness of deployment of sensors, utilization of penetrators as a quick deployment device in an emergent event is expected.

Dealing with locally-driven degradation: A quick start option under REDD+  

PubMed Central

The paper reviews a number of challenges associated with reducing degradation and its related emissions through national approaches to REDD+ under UNFCCC policy. It proposes that in many countries, it may in the short run be easier to deal with the kinds of degradation that result from locally driven community over-exploitation of forest for livelihoods, than from selective logging or fire control. Such degradation is low-level, but chronic, and is experienced over very large forest areas. Community forest management programmes tend to result not only in reduced degradation, but also in forest enhancement; moreover they are often popular, and do not require major political shifts. In principle these approaches therefore offer a quick start option for REDD+. Developing reference emissions levels for low-level locally driven degradation is difficult however given that stock losses and gains are too small to be identified and measured using remote sensing, and that in most countries there is little or no forest inventory data available. We therefore propose that forest management initiatives at the local level, such as those promoted by community forest management programmes, should monitor, and be credited for, only the net increase in carbon stock over the implementation period, as assessed by ground level surveys at the start and end of the period. This would also resolve the problem of nesting (ensuring that all credits are accounted for against the national reference emission level), since communities and others at the local level would be rewarded only for increased sequestration, while the national reference emission level would deal only with reductions in emissions from deforestation and degradation.

Formulation development of stronger and quick disintegrating tablets: a crucial effect of chitin.  

PubMed

A well known superdisintegrant like croscarmellose sodium or crospovidone loses their quick disintegration property when compressed at more than 4 kg tablet crushing strength (TCS). Therefore, the objective of the present work was to develop a disintegrating system that could be used for preparing fast disintegrating tablets (FDTs) of highly water soluble drug, metoclopramide, without compromising on the mechanical strength, irrespective of the TCS used for compressing the granules. For this purpose disintegrating system consisting of chitosan-alginate (CTN-ALG) complex (1:1): glycine and chitin was developed. The results revealed that when CTN-ALG and glycine were mixed in the ratio of 30:70, the granules exhibited a minimum water sorption time and maximum effective pore radius (R(eff.p)). The addition of chitin (5-10% w/w) into this mixture further enhanced the R(eff.p). Further, increase in the concentration of chitin from 10% to 20% w/w did not produce any significant effect (p>0.05) on the R(eff.p). The FDTs prepared by using CTN-ALG:glycine (30:70) and chitin exhibited increased porosity and lower disintegration time (DT). Further, chitin was found to neutralize the effect of TCS on DT of FDTs. This property of chitin was also observed in FDTs prepared by using croscarmellose sodium (5% w/w) or crospovidone (5% w/w). The reduction in DT of FDTs by chitin was also observed in tablets prepared without the drug. Hence, the effect was not influenced by the solubility component present in the tablets. Overall, the results suggested incorporation of chitin (5-10% w/w) while preparing FDTs of metoclopramide to enhanced the disintegration without compromising their mechanical strength of the tablets.

Second generation Tibetan lowlanders acclimatize to high altitude more quickly than Caucasians  

PubMed Central

Tibetan highlanders develop at altitude peak aerobic power levels (V?O2peak) close to those of Caucasians at sea level. In order to establish whether this feature is genetic and, as a consequence, retained by Tibetan lowlanders, altitude-induced changes of peak aerobic performance (?V?O2peak) were assessed in four groups of volunteers with different ethnic, altitude exposure and fitness characteristics, i.e. eight untrained second-generation Tibetans (Tib 2) born and living at 1300 m; seven altitude Sherpas living at ?2800–3500 m; and 10 untrained and five trained Caucasians. Measurements were carried out at sea level or at Kathmandu (1300 m, Nepal) (PRE), and after 2–4 (ALT1), 14–16 (ALT2), and 26–28 (ALT3) days at 5050 m. At ALT3, ?V?O2peak of untrained and trained Caucasians was –31% and –46%, respectively. By contrast, ?V?O2peak of Tib 2 and Sherpas was –8% and –15%, respectively. At ALT3, peak heart rate (HRpeak) of untrained and trained Caucasians was 148 ± 11 and 149 ± 7 beats min?1, respectively; blood oxygen saturation at peak exercise (SaO2peak) was 76 ± 6% and 73 ± 6%, and haemoglobin concentration ([Hb]) was 19.4 ± 1.0 and 18.6 ± 1.2 g dl?1, respectively. Compared to Caucasians, Tib 2 and Sherpas exhibited at ALT3 higher HRpeak (179 ± 9 and 171 ± 4 beats min?1, P < 0.001), lower [Hb] (16.6 ± 0.6 and 17.4 ± 0.9 g dl?1, respectively, P < 0.001), and slightly but non-significantly greater average SaO2peak values (82 ± 6 and 80 ± 7%). The above findings and the time course of adjustment of the investigated variables suggest that Tibetan lowlanders acclimatize to chronic hypoxia more quickly than Caucasians, independent of the degree of fitness of the latter.

In vitro wear of Ionofil Molar AC quick glass-ionomer cement.  

PubMed

Aim: The aim of this study was to evaluate the three-body wear-resistance of one type of restorative glass-ionomer cement (GIC). Materials and Methods: Specimen including conventional GIC (Ionofil Molar AC Quick: IMACQ), hybrid ionomer (Fuji II LC), and composite resin (Heliomolar) were tested in a wearing machine. In this machine, a 6?kg load was applied via pressable chromium-cobalt bar at 5,000, 10,000, 20,000, 40,000, 80,000, 120,000 cycles. Specimen weight was measured by an electronical weight balance before and after each cycle. Data were analyzed using one-way analysis of variance (ANOVA) followed by a t-test, and a paired t-test at P?0.05. Results: The highest weight loss has been found in Fuji II LC, then in GIC IMACQ and the least wear rate has been reported in heliomolar composite in all cycles except 120,000 cycles. In 120,000 cycles, the highest weight loss was seen in GIC IMACQ, then Fuji II LC, and finally heliomolar composite. There was a statistically significant difference in weight loss between GIC IMACQ and heliomolar composite (P=0/001). Conclusion: The wear rate of GIC IMACQ was between those of heliomolar composite and Fuji II LC glass ionomer in all cycles except 120,000 cycles. The most important advantage of this new-generation glass ionomer is its good manipulability and also high wear-resistance compared to the hybrid ionomer. Therefore, it is suggested that it can be used as restorative material in class I restorations in primary teeth. PMID:22406725

A new flexible monochromator setup for quick scanning x-ray absorption spectroscopy  

NASA Astrophysics Data System (ADS)

A new monochromator setup for quick scanning x-ray absorption spectroscopy in the subsecond time regime is presented. Novel driving mechanics allow changing the energy range of the acquired spectra by remote control during data acquisition for the first time, thus dramatically increasing the flexibility and convenience of this method. Completely new experiments are feasible due to the fact that time resolution, edge energy, and energy range of the acquired spectra can be changed continuously within seconds without breaking the vacuum of the monochromator vessel and even without interrupting the measurements. The advanced mechanics are explained in detail and the performance is characterized with x-ray absorption spectra of pure metal foils. The energy scale was determined by a fast and accurate angular encoder system measuring the Bragg angle of the monochromator crystal with subarcsecond resolution. The Bragg angle range covered by the oscillating crystal can currently be changed from 0° to 3.0° within 20 s, while the mechanics are capable to move with frequencies of up to ca. 35 Hz, leading to ca. 14 ms/spectrum time resolution. A new software package allows performing programmed scan sequences, which enable the user to measure stepwise with alternating parameters in predefined time segments. Thus, e.g., switching between edges scanned with the same energy range is possible within one in situ experiment, while also the time resolution can be varied simultaneously. This progress makes the new system extremely user friendly and efficient to use for time resolved x-ray absorption spectroscopy at synchrotron radiation beamlines.

Instrumental system for the quick relief of surface temperatures in fumaroles fields and steam heated soils  

NASA Astrophysics Data System (ADS)

We present an instrumental system to measure and to map the space variation of the surface temperature in volcanic fields. The system is called Pirogips, its essential components are a Pyrometer and a Global Position System but also other devices useful to obtain a good performance of the operating system have been included. In the framework of investigation to define and interpret volcanic scenarios, the long-term monitoring of gas geochemistry can improve the resolution of the scientific approaches by other specific disciplines. Indeed the fluid phase is released on a continuous mode from any natural system which produces energy in excess respect to its geological boundaries. This is the case of seismic or magmatic active areas where the long-term geochemical monitoring is able to highlight, and to follow in real time, changes in the rate of energy release and/or in the feeding sources of fluids, thus contributing to define the actual behaviour of the investigated systems (e.g. Paonita el al., 2013; 2002; Taran, 2011; Zettwood and Tazieff, 1973). The demand of pirogips starts from the personal experience in long term monitoring of gas geochemistry (e.g. Diliberto I.S, 2013; 2011; et al., 2002; Inguaggiato et al.,2012a, 2012b). Both space and time variation of surface temperature highlight change of energy and mass release from the deep active system, they reveal the upraise of deep and hot fluid and can be easily detected. Moreover a detailed map of surface temperature can be very useful for establishing a network of sampling points or installing a new site for geochemical monitoring. Water is commonly the main component of magmatic or hydrothermal fluid release and it can reach the ground surface in the form of steam, as in the high and low temperature fumaroles fields, or it can even condense just below the ground surface. In this second case the water disperses in pores or circulates in the permeable layers while the un-condensable gases reach the surface (e.g. in mofettes and diffuse degassing areas). The occurrence of thermal anomalies at the surface often reveals that a process of steam condensation is occurring below the ground and that CO2 fluxes are being released on the surface. A thermal map of steam heated grounds therefore highlights boundaries of underground steam advection and also the more suitable sites for geochemical monitoring. Pirogips has been assembled for the quick acquisition of surface parameters related to the exhaling activity of volcanic systems. It has been formerly tested in a controlled environment, after in the well known fumaroles areas of Vulcano island, and then in the volcanic system El Machin (Colombia) for the field survey preliminary to the installation of new monitoring stations. The preliminary test and the first field experiences confirmed that pirogips acquires the surface temperatures quickly and with good detail. The combination of sensors supplies the advantage of in situ methods (i.e. accuracy of the direct measurement by thermocouple) and those of ground-based remote sensing techniques (i.e. quickness of measurement process), at the same time reducing the main disadvantages of each method. A home-made data-logger combines the acquired parameters and returns a data-string allowing an easy visualization of acquired data on geo-referenced maps. The string of data returns the position of acquisition (lat, long, WGS84), surface temperature (either derived by the pyrometer and by thermocouple), ambient temperature, barometric pressure and air moisture. -References -Diliberto I.S., Gurrieri S., Valenza M.

Emergency product generation for disaster management using RISAT and DMSAR quick look SAR processors  

NASA Astrophysics Data System (ADS)

Since last few years, ISRO has embarked upon the development of two complex Synthetic Aperture Radar (SAR) missions, viz. Spaceborne Radar Imaging Satellite (RISAT) and Airborne SAR for Disaster Mangement (DMSAR), as a capacity building measure under country's Disaster Management Support (DMS) Program, for estimating the extent of damage over large areas (~75 Km) and also assess the effectiveness of the relief measures undertaken during natural disasters such as cyclones, epidemics, earthquakes, floods and landslides, forest fires, crop diseases etc. Synthetic Aperture Radar (SAR) has an unique role to play in mapping and monitoring of large areas affected by natural disasters especially floods, owing to its unique capability to see through clouds as well as all-weather imaging capability. The generation of SAR images with quick turn around time is very essential to meet the above DMS objectives. Thus the development of SAR Processors, for these two SAR systems poses considerable challenges and design efforts. Considering the growing user demand and inevitable necessity for a full-fledged high throughput processor, to process SAR data and generate image in real or near-real time, the design and development of a generic SAR Processor has been taken up and evolved, which will meet the SAR processing requirements for both Airborne and Spaceborne SAR systems. This hardware SAR processor is being built, to the extent possible, using only Commercial-Off-The-Shelf (COTS) DSP and other hardware plug-in modules on a Compact PCI (cPCI) platform. Thus, the major thrust has been on working out Multi-processor Digital Signal Processor (DSP) architecture and algorithm development and optimization rather than hardware design and fabrication. For DMSAR, this generic SAR Processor operates as a Quick Look SAR Processor (QLP) on-board the aircraft to produce real time full swath DMSAR images and as a ground based Near-Real Time high precision full swath Processor (NRTP). It will generate full-swath (6 to 75 Kms) DMSAR images in 1m / 3m / 5m / 10m / 30m resolution SAR operating modes. For RISAT mission, this generic Quick Look SAR Processor will be mainly used for browse product generation at NRSA-Shadnagar (SAN) ground receive station. RISAT QLP/NRTP is also proposed to provide an alternative emergency SAR product generation chain. For this, the S/C aux data appended in Onboard SAR Frame Format (x, y, z, x', y', z', roll, pitch, yaw) and predicted orbit from previous days Orbit Determination data will be used. The QLP / NRTP will produce ground range images in real / near real time. For emergency data product generation, additional Off-line tasks like geo-tagging, masking, QC etc needs to be performed on the processed image. The QLP / NRTP would generate geo-tagged images from the annotation data available from the SAR P/L data itself. Since the orbit & attitude information are taken as it is, the location accuracy will be poorer compared to the product generated using ADIF, where smoothened attitude and orbit are made available. Additional tasks like masking, output formatting and Quality checking of the data product will be carried out at Balanagar, NRSA after the image annotated data from QLP / NRTP is sent to Balanagar. The necessary interfaces to the QLP/NRTP for Emergency product generation are also being worked out. As is widely acknowledged, QLP/NRTP for RISAT and DMSAR is an ambitious effort and the technology of future. It is expected that by the middle of next decade, the next generation SAR missions worldwide will have onboard SAR Processors of varying capabilities and generate SAR Data products and Information products onboard instead of SAR raw data. Thus, it is also envisaged that these activities related to QLP/NRTP implementation for RISAT ground segment and DMSAR will be a significant step which will directly feed into the development of onboard real time processing systems for ISRO's future space borne SAR missions. This paper describes the design requirements, configuration details and salient features, apart from

Evaluation of QuickVue, a rapid enzyme immunoassay test for the detection of serum antibodies to Helicobacter pylori.  

PubMed

QuickVue is an enzyme immunoassay test for qualitative detection of serum immunoglobulin-G antibodies to Helicobacter pylori. We evaluated its ability to predict infection by H. pylori in 100 adult and 49 pediatric patients referred for gastric endoscopy. A patient was defined as infected with H. pylori if either culture or histology was positive. Of the 100 adult patients, 64 had H. pylori infection and QuickVue correctly identified 59 of the 64. Of 36 H. pylori-negative patients, 20 were correctly identified as negative by the test. In this sample of patients, QuickVue had a sensitivity of 92% and a specificity of 56%. In the 49 pediatric patients, QuickVue correctly identified nine of 11 infected cases and 34 of 38 noninfected patients. In this group, the sensitivity was 82% and the specificity was 89%. Overall the test had a sensitivity of 91% and a specificity of 73%. The positive predictive value was 77% and the negative predictive value was 89%. PMID:8495587

TEC ingestion into NeQuick 2 to model the topside electron density in the East-African ionosphere  

NASA Astrophysics Data System (ADS)

This study investigates the performances of the NeQuick 2 empirical model in the East-African region by assisting this model with Global Positioning System (GPS) measurements obtained from a single station. First we calculate an effective ionization level that drives NeQuick 2 to reproduce TEC that fits the least square sense to the measurements. We then quantify the performances of the NeQuick 2 in reproducing the topside in situ ion density observed by Communication/ Navigation Outage Forecast System (C/NOFS) satellite after modifying the model's input parameter. This is done by inputting the effective ionization level calculated from the slant total electron content (sTEC) measurements obtained from the single GPS receiver to the model. The performances of the model before and after data ingestion are then investigated by comparing the model results with the topside in situ ion density observation. One-month data during low solar activity conditions were used in this study. We have shown that the capability of NeQuick 2 to specify the East-African region topside ionosphere has been increased substantially by means of data ingestion. We found that the model after ingestion reproduces the in situ topside ion density observations better as far as about 824 km away from the reference station than that before adaptation. In this study, the statistical comparisons of the performances of the model in reproducing topside in situ ion density observations before and after ingestion are also discussed.

Using NIR Photography to Document Snow Stratigraphy Quickly: Lessons from Three Field Campaigns  

NASA Astrophysics Data System (ADS)

We began using near-infrared (NIR) photography as a quick way to document snow stratigraphy in 2006 as part a snow validation campaign in Barrow, Alaska. Seventeen snow pits (30 to 80 cm deep) were photographed using a Sony DSC-P200 Cybershot 7.2-megapixel digital camera supported on a mini-tripod and equipped with a NIR filter (850 nm). Standard layer measurements of thickness, density, grain size, hardness, and grain type were also made in each pit. During the 2007 SnowSTAR traverse across Alaska and Canada, 43 snow pits were photographed and measured in the same fashion. During the CLPX-Alaska campaign of 2008, three trenches each about 10 m long were photographed in their entirety as well as documented in a traditional manner, this time using a Fuji S9100 9 mega-pixel digital camera with an 850 nm filter. For the trenches, the camera was supported on a sliding rail system. NIR photographs were processed using Image-J software and a simple algorithm that enhanced contrast based on grain size. Our goal is to develop a method of documenting stratigraphy that is faster than recording the results in a field book. For a 50 cm deep pit prior methods of recording stratigraphy would have required about 30 minutes. We succeeded in reducing the average time to acquire a pit photograph to less than 15 minutes. However, pit face preparation time increased by about 15 minutes because of the need to produce a smooth, divot-free snow surface. Required protocols to compute grain size from the photos added a further 20 minutes or more if used, so frequently these were omitted. While at present there is no real net reduction in the time to record stratigraphy using NIR photography vs. older methods, the result is superior in all ways to our best previous efforts to "map" the stratigraphy though hand-recorded data. A combination of older traditional methods and NIR photography is strongly recommended as the best method to document the snow stratigraphy.

Scrapie infectivity is quickly cleared in tissues of orally-infected farmed fish  

PubMed Central

Background Scrapie and bovine spongiform encephalopathy (BSE) belongs to the group of animal transmissible spongiform encephalopathy (TSE). BSE epidemic in the UK and elsewhere in Europe has been linked to the use of bovine meat and bone meals (MBM) in the feeding of cattle. There is concern that pigs, poultry and fish bred for human consumption and fed with infected MBM would eventually develop BSE or carry residual infectivity without disease. Although there has been no evidence of infection in these species, experimental data on the susceptibility to the BSE agent of farm animals other than sheep and cow are limited only to pigs and domestic chicken. In the framework of a EU-granted project we have challenged two species of fish largely used in human food consumption, rainbow trout (Oncorhynchus mykiss) and turbot (Scophthalmus maximus), with a mouse-adapted TSE strain (scrapie 139A), to assess the risk related to oral consumption of TSE contaminated food. In trout, we also checked the "in vitro" ability of the pathological isoform of the mouse prion protein (PrPSc) to cross the intestinal epithelium when added to the mucosal side of everted intestine. Results Fish challenged with a large amount of scrapie mouse brain homogenate by either oral or parenteral routes, showed the ability to clear the majority of infectivity load. None of the fish tissues taken at different time points after oral or parenteral inoculation was able to provoke scrapie disease after intracerebral inoculation in recipient mice. However, a few recipient mice were positive for PrPSc and spongiform lesions in the brain. We also showed a specific binding of PrPSc to the mucosal side of fish intestine in the absence of an active uptake of the prion protein through the intestinal wall. Conclusion These results indicate that scrapie 139A, and possibly BSE, is quickly removed from fish tissues despite evidence of a prion like protein in fish and of a specific binding of PrPSc to the mucosal side of fish intestine.

Quick, "Imputation-free" meta-analysis with proxy-SNPs  

PubMed Central

Background Meta-analysis (MA) is widely used to pool genome-wide association studies (GWASes) in order to a) increase the power to detect strong or weak genotype effects or b) as a result verification method. As a consequence of differing SNP panels among genotyping chips, imputation is the method of choice within GWAS consortia to avoid losing too many SNPs in a MA. YAMAS (Yet Another Meta Analysis Software), however, enables cross-GWAS conclusions prior to finished and polished imputation runs, which eventually are time-consuming. Results Here we present a fast method to avoid forfeiting SNPs present in only a subset of studies, without relying on imputation. This is accomplished by using reference linkage disequilibrium data from 1,000 Genomes/HapMap projects to find proxy-SNPs together with in-phase alleles for SNPs missing in at least one study. MA is conducted by combining association effect estimates of a SNP and those of its proxy-SNPs. Our algorithm is implemented in the MA software YAMAS. Association results from GWAS analysis applications can be used as input files for MA, tremendously speeding up MA compared to the conventional imputation approach. We show that our proxy algorithm is well-powered and yields valuable ad hoc results, possibly providing an incentive for follow-up studies. We propose our method as a quick screening step prior to imputation-based MA, as well as an additional main approach for studies without available reference data matching the ethnicities of study participants. As a proof of principle, we analyzed six dbGaP Type II Diabetes GWAS and found that the proxy algorithm clearly outperforms naïve MA on the p-value level: for 17 out of 23 we observe an improvement on the p-value level by a factor of more than two, and a maximum improvement by a factor of 2127. Conclusions YAMAS is an efficient and fast meta-analysis program which offers various methods, including conventional MA as well as inserting proxy-SNPs for missing markers to avoid unnecessary power loss. MA with YAMAS can be readily conducted as YAMAS provides a generic parser for heterogeneous tabulated file formats within the GWAS field and avoids cumbersome setups. In this way, it supplements the meta-analysis process.

Laser desorption/ionization mass spectrometry on nanostructured semiconductor substrates: DIOS(TM) and QuickMass(TM)  

NASA Astrophysics Data System (ADS)

In the era of systems biology, new analytical platforms are under demand. Desorption/ionization on silicon mass spectrometry (DIOS-MS) is a promising high throughput laser mass spectrometry approach that has attracted a lot of attention, and has been commercialized. Another substrate material manufactured by physical method has also been made commercially available under the trade name of QuickMass(TM). These two commercial substrates, DIOS(TM) and QuickMass(TM), were investigated independently from the manufacturers and were characterized by a number of advanced surface techniques. This work determined (1) the correlation between the substrate physicochemical properties and their LDI activity, (2) the feasibility of metabolic profiling from complex biological matrices and (3) the laser desorption/ionization mechanism. The DIOS(TM) substrate was characterized with a thick nano-sized porous layer, a high surface concentration of fluorocarbon and silicon oxides and super-hydrophobicity. In contrast, the QuickMass(TM) substrate consisted of a non-porous germanium thin-film. The relatively high ionization efficiency obtained from the DIOS(TM) substrate was contributed to the fluorosilane manufacturing processes and its porous morphology. Despite the QuickMass(TM) substrate being less effective, it was noted that the use of germanium affords a self-cleaning mechanism and suppresses background interference of mass spectra. The suitability of DIOS(TM) substrates for metabolic profiling of complex biological matrices was demonstrated. DIOS mass spectra of human blood plasma, human urine and animal liver tissue extracts were produced. Suitable extraction methods were found to be important, but relatively simplified approaches were sufficient. Further investigations of the DIOS desorption/ionization mechanism were carried out. The previously proposed sub-surface state reaction could be a molten-solid interfacial state reaction of the substrate and this had a significant effect toward the protonation reaction of amines.

A Race for Survival: Can Bromus tectorum Seeds Escape Pyrenophora semeniperda-caused Mortality by Germinating Quickly?  

PubMed Central

Background and Aims Pathogen–seed interactions may involve a race for seed resources, so that seeds that germinate more quickly, mobilizing reserves, will be more likely to escape seed death than slow-germinating seeds. This race-for-survival hypothesis was tested for the North American seed pathogen Pyrenophora semeniperda on seeds of the annual grass Bromus tectorum, an invasive plant in North America. In this species, the seed germination rate varies as a function of dormancy status; dormant seeds germinate slowly if at all, whereas non-dormant seeds germinate quickly. Methods Three experimental approaches were utilized: (a) artificial inoculations of mature seeds that varied in primary dormancy status and wounding treatment; (b) naturally inoculated undispersed seeds that varied in primary dormancy status; and (c) naturally inoculated seeds from the carry-over seed bank that varied in degree of secondary dormancy, habitat of origin and seed age. Key Results In all three approaches, seeds that germinated slowly were usually killed by the pathogen, whereas seeds that germinated quickly frequently escaped. Pyrenophora semeniperda reduced B. tectorum seed banks. Populations in drier habitats sustained 50 times more seed mortality than a population in a mesic habitat. Older carry-over seeds experienced 30 % more mortality than younger seeds. Conclusions Given the dramatic levels of seed death and the ability of this pathogen to reduce seed carry-over, it is intriguing to consider whether P. semeniperda could be used to control B. tectorum through direct reduction of its seed bank.

Quick Look Report for Chemical Reactivity Modeling of Various Multi-Canister Overpack Breaches  

SciTech Connect

This report makes observations or shows trends in the response and does not specifically provide conclusions or predict the onset of bulk uranium oxidation safety margins based on hole size. Comprehensive analysis will be provided in the future. The report should animate discussions about the results and what should be analyzed further in the final analysis. This report intends only to show the response of the breached multi-canister overpack (MCO) as a function of event time using the GOTH_SNF computer code. The response will be limited to physical quantities available on the exterior of the MCO. The GOTH_SNF model is approximate, because not all physical phenomenon was included in the model. Error estimates in the response are not possible at this time, because errors in the actual physical data are not known. Sensitivities in the results from variations in the physical data have not been pursued at this time, either. This effort was undertaken by the National Spent Nuclear Fuel Program to evaluate potential chemical reactivity issues of a degraded uranium metal spent nuclear fuel using the MCO fully loaded with Mark IV N-reactor fuel as the evaluation model. This configuration is proposed for handling in the Yucca Mountain Project (YMP) surface facility. Hanford is loading N-reactor fuel elements into the MCO for interim storage at the Hanford site with permanent disposal proposed at YMP. A portion of the N-reactor fuel inventory has suffered corrosion, exposing the uranium metal under the zircaloy cladding. Because of the sealed MCO, the local radiation field, and decay heat of the fuel, hydrogen production cannot be ruled out from the metal hydrates on the surface of the zircaloy cladding and exposed fuel. Because of the much greater surface area, the oxyhydroxide composition, and water of hydration in the uranium metal corrosion product, the corrosion product will be a significant water source that may equal the absorbed water on the zircaloy cladding. A uranium oxide coating covers the exposed uranium metal, yet uranium hydride can still form under the protective oxide coating over the 40-year interim storage time span. The current treatment process at Hanford does not remove chemically bound water contained in the hydrates or in the waters of hydration. The chemically bound water is the source material for hydrogen production over the 40-year storage time. So, additional uranium hydride creates concerns that breaches of an MCO with the appropriate size openings could result in the onset of bulk uranium oxidation with the potential of a self-sustaining thermal excursion or pyrophoric event. For this analysis, the worst-case scenario appears to be the match head configuration in a vertically standing MCO, where all the reactive surface area is placed on the tips of the fuel elements. This configuration concentrates the heat-producing chemical reaction at the tips of the fuel elements. Because no mechanistic drop analysis has been performed at this time to determine the MCO failure modes, parametric breach configurations were chosen in this analysis to determine the MCOs’ external thermal response range. The first breach is a pair of holes that suddenly open in the MCO wall. This thermal excursion is controlled by the “thermal chimney effect” in the 4.27-m (14-ft) tall canisters caused by the multiple holes breach (one high and one low). A second breach where the MCO lid is suddenly removed and exposed to the ambient air

Influence of the paraoxonase-1 Q192R genetic variant on clopidogrel responsiveness and recurrent cardiovascular events: a systematic review and meta-analysis  

PubMed Central

Summary Background A poor biological response to clopidogrel is associated with an increased risk of major cardiovascular ischemic events (MACE). Paraoxonase 1 (PON1) enzyme activity is modulated by the PON1-Q192R variant (rs662) and was recently suggested to be strongly involved in clopidogrel bioactivation, but the influence of the PON1-Q192R variant on the risk of MACE in clopidogrel-treated patients is controversial. Objectives To determine whether the PON1-Q192R variant influences clopidogrel biological responsiveness and the risk of MACE in patients treated with clopidogrel. Methods Systematic review and meta-analysis of studies of the association between the PON1-Q192R polymorphism and the biological response to clopidogrel and/or the risk of MACE during clopidogrel administration. Results Seventeen studies were included. In the 12 studies of the biological response to clopidogrel (n = 5302 patients), there was no significant difference between 192QQ and 192QR + 192RR subjects, whatever the laboratory method used (global mean standardized difference = 0.10 [?0.06; 0.25], P = 0.22). Eleven studies assessed the risk of MACE, four using a case–control design (n = 2739 patients) and seven a prospective design (n = 5353 patients). Overall, MACE occurred in 19% of patients in case–control studies and in 6% of patients in prospective cohort studies, with no significant difference between 192QQ and 192QR + 192RR patients (OR = 1.28 [0.97; 1.68], P = 0.08). Similar results were obtained when study design was taken into account. Heterogeneity was mainly driven by one publication. Conclusions This meta-analysis suggests that the PON1-Q192R polymorphism has no major impact on the risk of MACE and does not alter the biological response to clopidogrel in clopidogrel-treated patients.

The protective effect of rapid cold-hardening develops more quickly in frozen versus supercooled larvae of the Antarctic midge, Belgica antarctica.  

PubMed

During the austral summer, larvae of the terrestrial midge Belgica antarctica (Diptera: Chironomidae) experience highly variable and often unpredictable thermal conditions. In addition to remaining freeze tolerant year-round, larvae are capable of swiftly increasing their cold tolerance through the rapid cold-hardening (RCH) response. The present study compared the induction of RCH in frozen versus supercooled larvae. At the same induction temperature, RCH occurred more rapidly and conferred a greater level of cryoprotection in frozen versus supercooled larvae. Furthermore, RCH in frozen larvae could be induced at temperatures as low as -12°C, which is the lowest temperature reported to induce RCH. Remarkably, as little as 15 min at -5°C significantly enhanced larval cold tolerance. Not only is protection from RCH acquired swiftly, but it is also quickly lost after thawing for 2 h at 2°C. Because the primary difference between frozen and supercooled larvae is cellular dehydration caused by freeze concentration of body fluids, we also compared the effects of acclimation in dehydrated versus frozen larvae. Because slow dehydration without chilling significantly increased larval survival to a subsequent cold exposure, we hypothesize that cellular dehydration caused by freeze concentration promotes the rapid acquisition of cold tolerance in frozen larvae.

Determination of the Failure Surface Geometry in Quick Slides Using Balanced Cross Section Techniques - Application to Aznalcóllar Tailings Dam Failure  

NASA Astrophysics Data System (ADS)

In a landslide investigation, the location of the failure surface is a difficult task when measures of subsurface displacement are lacking, as it occurs in old landslides or in recent but quick ones. The subsurface geological data and ground surface displacement data may not be enough to formulate a unique interpretation of the failure surface. However, an accurate determination of the failure surface is possible when balanced cross section techniques are applied to preliminary interpretations. The former is proved by means of the example of Aznalcóllar dam failure (Seville, Spain).

The development of a quick-running prediction tool for the assessment of human injury owing to terrorist attack within crowded metropolitan environments  

PubMed Central

In the aftermath of the London ‘7/7’ attacks in 2005, UK government agencies required the development of a quick-running tool to predict the weapon and injury effects caused by the initiation of a person borne improvised explosive device (PBIED) within crowded metropolitan environments. This prediction tool, termed the HIP (human injury predictor) code, was intended to: —?assist the security services to encourage favourable crowd distributions and densities within scenarios of ‘sensitivity’;—?provide guidance to security engineers concerning the most effective location for protection systems;—?inform rescue services as to where, in the case of such an event, individuals with particular injuries will be located;—?assist in training medical personnel concerning the scope and types of injuries that would be sustained as a consequence of a particular attack;—?assist response planners in determining the types of medical specialists (burns, traumatic amputations, lungs, etc.) required and thus identify the appropriate hospitals to receive the various casualty types.This document describes the algorithms used in the development of this tool, together with the pertinent underpinning physical processes. From its rudimentary beginnings as a simple spreadsheet, the HIP code now has a graphical user interface (GUI) that allows three-dimensional visualization of results and intuitive scenario set-up. The code is underpinned by algorithms that predict the pressure and momentum outputs produced by PBIEDs within open and confined environments, as well as the trajectories of shrapnel deliberately placed within the device to increase injurious effects. Further logic has been implemented to transpose these weapon effects into forms of human injury depending on where individuals are located relative to the PBIED. Each crowd member is subdivided into representative body parts, each of which is assigned an abbreviated injury score after a particular calculation cycle. The injury levels of each affected body part are then summated and a triage state assigned for each individual crowd member based on the criteria specified within the ‘injury scoring system’. To attain a comprehensive picture of a particular event, it is important that a number of simulations, using what is substantively the same scenario, are undertaken with natural variation being applied to the crowd distributions and the PBIED output. Accurate mathematical representation of such complex phenomena is challenging, particularly as the code must be quick-running to be of use to the stakeholder community. In addition to discussing the background and motivation for the algorithm and GUI development, this document also discusses the steps taken to validate the tool and the plans for further functionality implementation.

A quick LC-MS-MS method for the determination of flunixin in bovine muscle.  

PubMed

A simple, fast and cost-effective liquid chromatographic/tandem mass spectrometry (LC-MS-MS) method for the quantitative determination of flunixin (FLU) in bovine muscle was developed and validated. The sample preparation procedure involved an extraction with acetonitrile, followed by evaporation and reconstitution. Chromatographic separation was achieved on a reverse-phase column under programmed conditions. FLU detection was performed with positive electrospray ionization in selected reaction monitoringmode, monitoring one precursor and two products ions. For quantification purposes, FLU-d3 was used as an internal standard. The matrix effect on the analysis of FLU in bovine muscle was evaluated by comparison between calibration curves prepared with standard solution and in blank matrix extracts. The equivalent responses obtained confirmed the absence of signal suppression or/and enhancement. The method was extensively validated according to the parameters requested by European Commission Decision 2002/657/EC in terms of specificity, limit of detection, linearity, trueness, precision, decision limit (CC?) and detection capability (CC?). FLU stability was also investigated in matrix and in sample extracts at different times and storage conditions. PMID:24396052

Onsets do not override top-down goals, but they are responded to more quickly.  

PubMed

Do onsets automatically capture attention? Spatial-cuing experiments often reveal no capture by onset cues in searches for color targets. However, recent experiments have shown faster responses to an uncued color target presented as an abrupt onset than as a change to an existing item, which has been argued to reflect capture by the onset. In the present experiment, we tested whether this onset advantage reflects the capture of attention or processing independent of shifts of attention. In a modified spatial-cuing paradigm, noninformative color precues were paired with color targets presented as abrupt onsets or as no-onset characters. Critically, the number of other onset items in the target display was manipulated, which has previously been shown to disrupt attention allocation to any particular item. It was reasoned that if the onset advantage for uncued color targets reflects attentional capture, then the appearance of additional onsets should eliminate this advantage. The results showed that even with multiple onsets on the target display, the onset advantage remained additive with cue validity. The additive effects are inconsistent with automatic capture by onsets, suggesting instead that the onset advantage arises from an independent source. PMID:24596080

Growing up too quickly: Children who lose out on their childhoods  

PubMed Central

Despite the almost universal ratification of the Convention on the Rights of the Child, summits and conferences organized by international and local agencies, the awareness campaigns and the immense work performed by nongovernmental organizations, too many children continue to endure hardship. It is estimated that 8.4 million children are involved in the worst forms of child labour, namely labour that involves forced or bonded labour, sexual exploitation, illicit work and armed conflicts. The impact of such activities on the survival, health (both physical and mental) and development of children is devastating. Girls are particularly vulnerable. But children are resilient, and although longitudinal data on the validity of the programmes are not yet available, rehabilitation programs adapted to their own culture and reinsertion in their communities have shown positive results. Along with monitoring, research, education and rehabilitation, paediatricians have the responsibility, as physicians and advocates for children, to promote the respect of children’s rights while, at the same time, searching for solutions to eradicate poverty and prevent war. There should be zero tolerance for those who violate children’s rights.

Insights into quick flow in a karst aquifer: Usefulness of infrequently collected geochemical data from wells  

SciTech Connect

Highly variable chemical characteristics (e.g., hardness) can indicate that a portion of a karst aquifer sampled by a well is subject to a quickflow component where water flow is rapid and water quality changes rapidly in response to precipitation events. Typically, karst aquifer monitoring for both water level and geochemistry is conducted at frequent intervals (hourly, daily) due to the nature of rapid geochemical and hydrologic changes in association with storm events. Quarterly monitoring data are available at the U.S. Department of Energy Oak Ridge Y- 12 Plant in Oak Ridge, TN, and these data are evaluated to identify quickflow portions of the aquifer. Values of P{sub CO{sub 2}} near atmospheric suggest rapid recharge of fluids, and 12 of 99 well waters exhibited P{sub CO{sub 2}} near atmospheric. Waters saturated with respect to dolomite must have relatively long residence times because attainment of saturation requires tens to hundreds of years. Repeat sampling of waters shows that both supersaturation and undersaturation with respect to dolomite occurs in 46 wells, indicating that relatively old waters diffusing from the rock matrix into conduits during baseflow experience periodic flushing by more rapidly recharged waters. Undersaturation with respect to calcite indicates active dissolution and may suggest short residence times because calcite saturation can be expected to occur on the order of days. Evaluation of a{sub Mg}/a{sub Ca} ratios in the waters allows identification of portions of the aquifer where flow occurs from a dolomite to a limestone, and vice versa. In addition, 30 well waters exhibited coefficients of variation of hardness >10%. Hence, quickflow was identified in association with numerous well waters even though only quarterly monitoring data were available.
