    Insomnia is a serious worldwide health problem that is often comorbid with anxiety. The purpose of the present study was to evaluate the efficacy of a Chinese formula containing Suan Zao Ren Tang (SZRT) and Zhi Zi Chi Tang (ZZCT; SZR-ZZC) for improving sleep quality and anxiety states with four indices of Polysomnography (PSG), the Insomnia Severity Index (ISI), the Pittsburgh Sleep Quality Index (PSQI), and the Self Rating Anxiety Scale (SAS). Methods. A randomized, parallel-controlled trial compared SZR-ZZC to lorazepam tablet in insomniacs with anxiety. Patients were randomized to the SZR-ZZC treatment group (n = 60) and the lorazepam tablet treatment group (n = 59). Results. SZR-ZZC significantly improved scores on all four treatment indices. Compared with lorazepam, treatment with SZR-ZZC resulted in a significant reduction in the ISI (P = 0.029), the PSQI (P = 0.017), and wake after sleep onset (WASO; P = 0.008) scores and improved sleep architecture (P = 0.000–0.003) after a 4-week treatment period. Only one subject in the SZR-ZZC group experienced adverse side effects. Conclusion. Treatment with SZR-ZZC for 4 weeks appears to be a relatively safe and effective complementary therapeutic option when aiming to improve sleep quality and anxiety in insomniacs with anxiety.

    Previously, it was time-consuming to hand-edit data and then set up simulation runs to find the effect and impact of the input data on a spacecraft. MPS Editor provides the user the capability to create/edit/update models and sequences, and immediately try them out using what appears to the user as one piece of software. MPS Editor provides an integrated sequencing environment for users. It provides them with software that can be utilized during development as well as actual operations. In addition, it provides them with a single, consistent, user friendly interface. MPS Editor uses the Eclipse Rich Client Platform to provide an environment that can be tailored to specific missions. It provides the capability to create and edit, and includes an Activity Dictionary to build the simulation spacecraft models, build and edit sequences of commands, and model the effects of those commands on the spacecraft. MPS Editor is written in Java using the Eclipse Rich Client Platform. It is currently built with four perspectives: the Activity Dictionary Perspective, the Project Adaptation Perspective, the Sequence Building Perspective, and the Sequence Modeling Perspective. Each perspective performs a given task. If a mission doesn't require that task, the unneeded perspective is not added to that project's delivery. In the Activity Dictionary Perspective, the user builds the project-specific activities, observations, calibrations, etc. Typically, this is used during the development phases of the mission, although it can be used later to make changes and updates to the Project Activity Dictionary. In the Adaptation Perspective, the user creates the spacecraft models such as power, data store, etc. Again, this is typically used during development, but will be used to update or add models of the spacecraft. The Sequence Building Perspective allows the user to create a sequence of activities or commands that go to the spacecraft. It provides a simulation of the activities and

    Background With advances in DNA re-sequencing methods and Next-Generation parallel sequencing approaches, there has been a large increase in genomic efforts to define and analyze the sequence variability present among individuals within a species. For very polymorphic species such as maize, this has lead to a need for intuitive, user-friendly software that aids the biologist, often with naïve programming capability, in tracking, editing, displaying, and exporting multiple individual sequence alignments. To fill this need we have developed a novel DNA alignment editor. Results We have generated a nucleotide sequence alignment editor (DNAAlignEditor) that provides an intuitive, user-friendly interface for manual editing of multiple sequence alignments with functions for input, editing, and output of sequence alignments. The color-coding of nucleotide identity and the display of associated quality score aids in the manual alignment editing process. DNAAlignEditor works as a client/server tool having two main components: a relational database that collects the processed alignments and a user interface connected to database through universal data access connectivity drivers. DNAAlignEditor can be used either as a stand-alone application or as a network application with multiple users concurrently connected. Conclusion We anticipate that this software will be of general interest to biologists and population genetics in editing DNA sequence alignments and analyzing natural sequence variation regardless of species, and will be particularly useful for manual alignment editing of sequences in species with high levels of polymorphism.

    Chimiak, Reine; Harris, Bernard; Williams, Phillip

    2013-01-01

    Basic Common Data Format (CDF) tools (e.g., cdfedit) provide no specific support for creating International Solar-Terrestrial Physics/Space Physics Data Facility (ISTP/SPDF) standard files. While it is possible for someone who is familiar with the ISTP/SPDF metadata guidelines to create compliant files using just the basic tools, the process is error-prone and unreasonable for someone without ISTP/SPDF expertise. The key problem is the lack of a tool with specific support for creating files that comply with the ISTP/SPDF guidelines. There are basic CDF tools such as cdfedit and skeletoncdf for creating CDF files, but these have no specific support for creating ISTP/ SPDF compliant files. The SPDF ISTP CDF skeleton editor is a cross-platform, Java-based GUI editor program that allows someone with only a basic understanding of the ISTP/SPDF guidelines to easily create compliant files. The editor is a simple graphical user interface (GUI) application for creating and editing ISTP/SPDF guideline-compliant skeleton CDF files. The SPDF ISTP CDF skeleton editor consists of the following components: A swing-based Java GUI program, JavaHelp-based manual/ tutorial, Image/Icon files, and HTML Web page for distribution. The editor is available as a traditional Java desktop application as well as a Java Network Launching Protocol (JNLP) application. Once started, it functions like a typical Java GUI file editor application for creating/editing application-unique files.

    They are unalike and far apart, these 13 past editors of The Journal. Between Nathan S. Davis's first issue and William R. Barclay's retirement, there was almost a century of change in medicine, society, the American Medical Association, prose style, and editorial needs. During these years, the editors ranged from the brilliant organizers John B. Hamilton and George H. Simmons to the diligent John H. Hollister and the devoted Johnson F. Hammond. There were editors with the hot determination of James C. Culbertson, John H. Talbott, and Robert H. Moser, and there were those with the cool precision of Austin Smith and Hugh H. Hussey. They varied from Morris Fishbein, who wrote and spoke "with the grade of an eagle in its unhindered soar," to Truman W. Miller, who wrote scarcely a word. Here, briefly, they are together.

  13. PANEL LIBRARY AND EDITOR

    Raible, E.

    1994-01-01

    The Panel Library and Editor is a graphical user interface (GUI) builder for the Silicon Graphics IRIS workstation family. The toolkit creates "widgets" which can be manipulated by the user. Its appearance is similar to that of the X-Windows System. The Panel Library is written in C and is used by programmers writing user-friendly mouse-driven applications for the IRIS. GUIs built using the Panel Library consist of "actuators" and "panels." Actuators are buttons, dials, sliders, or other mouse-driven symbols. Panels are groups of actuators that occupy separate windows on the IRIS workstation. The application user can alter variables in the graphics program, or fire off functions with a click on a button. The evolution of data values can be tracked with meters and strip charts, and dialog boxes with text processing can be built. Panels can be stored as icons when not in use. The Panel Editor is a program used to interactively create and test panel library interfaces in a simple and efficient way. The Panel Editor itself uses a panel library interface, so all actions are mouse driven. Extensive context-sensitive on-line help is provided. Programmers can graphically create and test the user interface without writing a single line of code. Once an interface is judged satisfactory, the Panel Editor will dump it out as a file of C code that can be used in an application. The Panel Library (v9.8) and Editor (v1.1) are written in C-Language (63%) and Scheme, a dialect of LISP, (37%) for Silicon Graphics 4D series workstations running IRIX 3.2 or higher. Approximately 10Mb of disk space is required once compiled. 1.5Mb of main memory is required to execute the panel editor. This program is available on a .25 inch streaming magnetic tape cartridge in UNIX tar format for an IRIS, and includes a copy of XScheme, the public-domain Scheme interpreter used by the Panel Editor.

    1984-04-01

    It has been nearly a year since Ronald Cummings took over as policy sciences editor of Water Resources Research (WRR), and in that time he has worked to make the journal live up to its role as “an interdisciplinary journal integrating research in the social and natural sciences of water.” Cummings takes the “interdisciplinary” part seriously. “I'd like to see a much broader range of policy issues presented to readers,” he says. “I would hope it would then stimulate interchange between our colleagues concerning evolving issues of the '80s and '90s.”Cummings brings a solid background as a resource economist to his 4-year term as editor, which began last January and runs until December 1987. Cummings succeeds Jared Cohon as policy sciences editor. Stephen J. Burges is the WRR editor for hydrological, physical, chemical, and biological sciences. Now a Professor of Economics and Director of the Program in Natural Resources Economics at the University of New Mexico, Cummings is a past president of the Association of Environmental and Resource Economists. He has been a consultant in matters of water resources management, forestry management, and energy policy for more than a decade, working on projects in both the United States and Latin America. Since joining the faculty at New Mexico in 1975, he has, among other things, worked with engineers at the Los Alamos National Laboratory in developing operation'management models for hot, dry rock geothermal systems.

    2013-01-01

    The configuration of ION (Inter - planetary Overlay Network) network nodes is a manual task that is complex, time-consuming, and error-prone. This program seeks to accelerate this job and produce reliable configurations. The ION Configuration Editor is a model-based smart editor based on Eclipse Modeling Framework technology. An ION network designer uses this Eclipse-based GUI to construct a data model of the complete target network and then generate configurations. The data model is captured in an XML file. Intrinsic editor features aid in achieving model correctness, such as field fill-in, type-checking, lists of valid values, and suitable default values. Additionally, an explicit "validation" feature executes custom rules to catch more subtle model errors. A "survey" feature provides a set of reports providing an overview of the entire network, enabling a quick assessment of the model s completeness and correctness. The "configuration" feature produces the main final result, a complete set of ION configuration files (eight distinct file types) for each ION node in the network.

    Hudson, R. P.

    1989-01-01

    The completion of Volume 26, 1989, marked the end of my tenure as Editor of Metrologia. My association with the journal, its parent body the Comité International des Poids et Mesures, its host organization the Bureau International des Poids et Mesures, the publishers Springer-Verlag and last (but by no means least) the Editorial Board, has been a pleasant one and I trust that the subscribers will have found the product to be generally satisfactory. There have been, it is true, some disappointments along the way and I shall mention two of these while expressing the hope that the new Editor will enjoy a greater success in their regard. First is the question of circulation, which has stayed dangerously low, although the shrinkage has tapered off in the most recent years. Because of the narrow public support, the costs of production are relatively high and this, through a consequently high subscription rate, tends to enshrine the unsatisfactory state of affairs. Modest schemes to broaden the journal's appeal and bring in a wider readership have foundered upon the first step, namely, that of procuring from staff members of the national standards laboratories the hoped-for articles which would discuss the state of the art in delivering the highest-quality measurement services to the public. However, some very interesting and bolder schemes are presently under discussion. I had also hoped to leaven the journal's content a little by regularly appearing articles on the latest developments within the great national laboratories. But, as with technical review articles, it has proven very difficult to find the right authors who can also spare the time, and only a few laboratories have found it possible to collaborate. In taking my leave, it remains for me to thank all the contributors, referees and readers for their support, to express the hope of an ever brighter future for Metrologia and to wish to the new Editor, Dr D A Blackburn, a happy and successful tenure.

    1990-01-01

    Since its first issue in 1965 Metrologia has had just three editors, a history of tenure which suggests that those who hold the post find in it sufficient to interest, occupy, challenge and amuse them. I see no reason to doubt that this happy circumstance will continue and look forward to my own period as editor with the intention of retaining, insofar as I am able to interpret them, the best traditions the journal has established so far. As I take up my editorial duties I have become aware that surrounding Metrologia there is a small community of authors, reviewers and readers on whose support the success of the journal entirely depends. It is a community in which the roles change daily with some of its members engaged, even simultaneously, as reader, reviewer and author. I am well aware that the goodwill extended to me as I enter this community is in no small part due the efforts of the outgoing editor, Dr Ralph Hudson, whose easy, engaging and courteous, yet firm, relationship with authors and reviewers emerges clearly from editorial correspondence. I thank him for that he has done and wish him an active and happy retirement. A short foray into the records of Metrologia shows - in the first editorial - that four main kinds of article were originally envisaged: research articles likely to contribute to progress in fundamental scientific measurements, reports of experiments or techniques of particular importance or originality in the area of secondary measurement, articles concerning the decisions of the Comité International des Poids et Mesures, and review articles. No balance was specified but a priority was assigned to articles dealing with fundamental metrology. Of the four categories, the first two represent the core of Metrologia's activity and largely determine its reputation as a publication. For this reason, editorial implementation of the policy set by the CIPM is mainly exercised through the operation of a reviewing system which is intentionally strict

    This last year being an odd numbered year, the pages of Nuclear Fusion saw a large influx of expanded papers from the 2012 Fusion Energy Conference in San Diego. Many papers have focused on the scientific and technical challenges posed by ITER. Contributions are steadily increasing from the new superconducting tokamaks in Asia. The ITER Project continues to move ahead. Construction at the Cadarache site is quite remarkable. Buildings completed include the huge Poloidal Field Coils Winding Facility and the Headquarters building, which has been occupied by the ITER staff. Work is progressing on the Assembly building and the Cryostat Workshop. The base of the tokamak complex is being laid. Besides the construction that is taking place and will take place at the site, components from around the world have to navigate the complex route from Marseilles to the site. A test convoy replicating the dimensions and weights of the most exceptional ITER loads successfully traversed that route in 2013. We are pleased to report that the IAEA and ITER have finalized the agreement for ITER authors to publish papers in Nuclear Fusion .

    . Their scheme is embedded in an experimental ATM network with the potential for guaranteed QoS. The system features QoS support mechanisms in both the network and the end systems. Of particular interest is reported experience with a dynamic QoS adaptation protocol implemented in the network and based on video scaling techniques and filtering. In summary, this special issue provides an up to date review of approaches to QoS management and their practical realization. Of course, no claim is made as to comprehensiveness, but the chosen papers do serve as a highly representative sample of current directions in QoS research. The editors are very much obliged to all authors, reviewers and publishers. Without their excellent work, and the contribution of their valuable time this special issue would not have been possible.

  2. STE - The Software Tools Editor

    NASA Astrophysics Data System (ADS)

    Software tools is an excellent book written by B. W. Kernighan and P. J. Plauger, published by Addison-Wesley. In it the authors discuss how to write programs that make good tools, and how to program well in the process. One of the tools they develop is a fairly powerful editor, written in Ratfor (a structured form of FORTRAN IV). This program has been implemented on the UCL Starlink VAX (with a few modifications and extensions) and is recommended as the editor to use on the VAX. This note gives a brief introduction to, and description of, the editor which has been abstracted from the book (which you are recommended to buy). There are some short command summary sections at the end of this note. After reading this note you may like to print these short files and use them for reference when using the editor.

    Whilst travelling to Vienna to hand over the Editorship of Nuclear Fusion to Ron Stambaugh, I jotted down a few ideas to put in a farewell message. Somewhat unsurprisingly, I find them almost identical to the remarks that Chris Schueller made in handing over to me five years ago. Both of us served in this role for five years, which seems like a good timescale to replace presidents and editors alike; just to allow a fresh approach. In addition, since I have been directly involved in ITER, I have found it increasingly difficult, due to time pressure, to give the journal the attention that it deserves. Therefore, I am very pleased that Ron Stambaugh has agreed to take over as Editor. Not only does he bring the experience as a leading figure in the US fusion programme but, in addition, he has all the contacts, worldwide, from his leadership of the ITPA. I am completely assured that the journal is in a highly competent pair of hands. Such a farewell should not lack my heartfelt thanks to all of those who have made being Editor of Nuclear Fusion so enjoyable and stimulating; readership, authors, referees, the Editorial Board and the NF Office alike. I wish Ron all the best for his tenure and have offered such help and support as I am able to give.

  20. Tropospheric HO determination by FAGE

    NASA Technical Reports Server (NTRS)

    Hard, T. M.; Obrien, R. J.; Chan, C. Y.; Mehrabzadeh, A. A.

    1986-01-01

    In the detection of tropospheric HO by laser excited fluorescence, and alternative air-sampling method, named FAGE (Fluorescence Assay with Gas Expansion) was introduced. Here the air is expanded through a nozzle prior to excitation, in order to improve the ratio of the HO signal to the scattered, fluorescent, and photolytic backgrounds. The improvement comes from the differing pressure dependence of the intensities of these four terms, as well as the distinguishability of their temporal waveforms at low pressures when excited by a pulsed laser. HO has been excited by a YAG/dye laser. Other lasers and pumping paths may perform as well or better in this method. With FAGE, chemical modulation of the HO signal was achieved by hydrocarbon addition to the nozzle flow, converting photolytic HO from an interference to a background. Chemical calibration of the instrumental response to external HO was also achieved, by hydrocarbon decay, at HO concentrations within the ambient range.

    In the present work, HO2 is determined by FAGE, a method which employs low-pressure laser-excited fluorescence to observe the hydroxyl radical HO, using chemical modulation to distinguish the desired signal from the background. In the HO2 determination mode, NO is added to the low-pressure flowing sample, converting HO2 to HO.

    As usual, being an even year, the 23rd IAEA Fusion Energy Conference took place at Daejeon, Korea. The event was notable not just for the quality of the presentations but also for the spectacular opening ceremony, in the presence of the Prime Minister, Kim Hwang-sik. The Prime Minister affirmed the importance of research into fusion energy research and pledged support for ITER. Such political visibility is good news, of course, but it brings with it the obligation to perform. Fortunately, good performance was much in evidence in the papers presented at the conference, of which a significant proportion contain 'ITER' in the title. Given this importance of ITER and the undertaking by the Nuclear Fusion journal to publish papers associated with Fusion Energy Conference presentations, the Nuclear Fusion Editorial Board has decided to adopt a simplified journal scope that encompasses technology papers more naturally. The scope is available from http://iopscience.iop.org/0029-5515/page/Journal%20information but is reproduced here for clarity: Nuclear Fusion publishes articles making significant advances to the field of controlled thermonuclear fusion. The journal scope includes: the production, heating and confinement of high temperature plasmas; the physical properties of such plasmas; the experimental or theoretical methods of exploring or explaining them; fusion reactor physics; reactor concepts; fusion technologies. The key to scope acceptability is now '....significant advances....' rather than any particular area of controlled thermonuclear fusion research. It is hoped that this will make scope decisions easier for the Nuclear Fusion office, the referees and the Editor.The Nuclear Fusion journal has continued to make an important contribution to the research programme and has maintained its position as the leading journal in the field. This is underlined by the fact that Nuclear Fusion has received an impact factor of 4.270, as listed in ISI's 2009 Science Citation

  6. PROGRAMMABLE DISPLAY PUSHBUTTON LEGEND EDITOR

    NASA Technical Reports Server (NTRS)

    Busquets, A. M.

    1994-01-01

    The Programmable Display Pushbutton (PDP) is a pushbutton device available from Micro Switch which has a programmable 16 x 35 matrix of LEDs on the pushbutton surface. Any desired legends can be displayed on the PDPs, producing user-friendly applications which greatly reduce the need for dedicated manual controls. Because the PDP can interact with the operator, it can call for the correct response before transmitting its next message. It is both a simple manual control and a sophisticated programmable link between the operator and the host system. The Programmable Display Pushbutton Legend Editor, PDPE, is used to create the LED displays for the pushbuttons. PDPE encodes PDP control commands and legend data into message byte strings sent to a Logic Refresh and Control Unit (LRCU). The LRCU serves as the driver for a set of four PDPs. The legend editor (PDPE) transmits to the LRCU user specified commands that control what is displayed on the LED face of the individual pushbuttons. Upon receiving a command, the LRCU transmits an acknowledgement that the message was received and executed successfully. The user then observes the effect of the command on the PDP displays and decides whether or not to send the byte code of the message to a data file so that it may be called by an applications program. The PDPE program is written in FORTRAN for interactive execution. It was developed on a DEC VAX 11/780 under VMS. It has a central memory requirement of approximately 12800 bytes. It requires four Micro Switch PDPs and two RS-232 VAX 11/780 terminal ports. The PDPE program was developed in 1985.

In 2011 we have updated the editorial algorithm (revision by the responsible editor of all manuscripts sent to peer review and incorporated an «editorial coordinator»), we have renovated two advise facilities (editorial and scientific committees), we have created a new section called «monthly e-image», and we have promoted Rev Clin Esp annual prizes. From the first January 2010 to 31(st) October 2011 we handled 422 manuscripts (42,2 manuscripts per month, higher than the 2010 figure of 40,4 manuscript/month). Overall we have accepted 26% (originals, 16%). We asked for 343 revisions and obtained 231 (67%). Seventy two percent of the reviewers sent their comments in less than two weeks. The mean time taken to accept or reject a given manuscript has been 26 days. The mean time taken since a manuscript is received to publication (october, novembrer and december issues) has dropped from 334 days in 2010 to 254 in 2011 (24% decrease). The collaboration with the working groups has reported about 2 published manuscripts per issue. Our objectives for 2012 are: (a) to improve the editorial process; (b) main article translation into English; (c) improve some sections (i.e. clinical conference); (d) estimulate working groups collaboration; and (e) improve continued medical education. Revista Clínica Española is an open forum for all internal medicine specialists. We all have the responsibility to make our journal, each day, better.

The awards were presented by the IAEA Deputy Director General, Werner Burkart, and the Chairman of the Board of Editors, Mitsuru Kikuchi, on 16 October 2008 at the 22nd IAEA Fusion Energy Conference in Geneva, Switzerland. Given the topicality of these papers for the ITER design, it is a matter of pride to the journal that the work should be published in Nuclear Fusion. Reviews Like many who have worked for a long time in the field, I still make use of Nuclear Fusion Reviews that go back 20 or 30 years. It is particularly useful, therefore, that the Board of Editors has been working to re-activate the review programme. The first fruits will appear in this issue, in the form of `A review of zonal flow experiments', by Akihide Fujisawa. The special procedures for Reviews should be noted: most specifically that they should normally be commissioned by the Board of Editors. However, not only is the Board of Editors working on a programme but I am sure that they would be pleased to consider suggestions for review subjects. Letters The reputation of Nuclear

Fifteen (13%) out of the 119 original articles for which the editorial process was completed were accepted. Our goal for the year 2010 is to make the journal available on the Internet for all those who are subscribers to the Rev Clin Esp as well as for internal medicine residents (for which they must be members of each regional society). Other objectives of the editorial team are to edit the E-cases, for the journal to be a continuing education tool and that the coordinators of the work groups develop a monographic number at least once every two years. These actions aim to increase the impact factor and the quality of the Rev Clin Esp, official publication of the Spanish Society of Internal Medicine and of Spanish-speaking internal medicine physicians.

    Dear readers, contributors, and members of the world laser physics community. It is a great honour for us to introduce to you our new publishing partner, IOP Publishing, a subsidiary of the Institute of Physics, United Kingdom. IOP Publishing is a world renowned authority in producing journals, magazines, websites and services that enable researchers and research organizations to present their work to a world-wide audience. Laser Physics, the first English-language scientific journal in Russia, was founded in 1990 on the initiative of Alexander M Prokhorov, a pioneer and leader in laser physics research. Professor Prokhorov served as the first Editor-in-Chief of the journal until 2002. We are proud that it is our 23rd year of publishing Laser Physics and our 10th year of publishing Laser Physics Letters. We would like to honour the memory of our friend, late Professor Igor Yevseyev, whose enthusiasm and unwavering dedication to our journals contributed most significantly to their success. It was initially his idea in 2011 to approach IOP with a partnership proposal. We deeply regret that he is no longer with us as we enter this productive alliance. Now, in partnership with IOP, we are turning a new page in providing world-wide access to the cutting-edge research results in our journals, serving our well established global audience. We see new horizons opening for our journals for years to come and hope that our readers share our enthusiasm and aspirations. Please accept our best wishes for all your new scientific endeavors in the exciting field of laser physics.

    A laser host material LULF (LuLiF4) is doped with holmium (Ho) and thulium (Tm) to produce a new laser material that is capable of laser light production in the vicinity of 2 microns. The material provides an advantage in efficiency over conventional Ho lasers because the LULF host material allows for decreased threshold and upconversion over such hosts as YAG and YLF. The addition of Tm allows for pumping by commonly available GaAlAs laser diodes. For use with flashlamp pumping, erbium (Er) may be added as an additional dopant. For further upconversion reduction, the Tm can be eliminated and the Ho can be directly pumped.

    2005-06-01

    This study reports on ethical issues faced by editors of nursing journals, a topic which has not appeared in the nursing literature. A survey of nursing editors (n = 88)was conducted via e-mail; this article is the content analysis of survey questions about ethics. Eight categories of ethical issues emerged: problems with society/association/publisher; decisions about inflammatory submissions; informed consent or IRB issues; conflicts of interest; advertising pressures; duplicate publications and/or plagiarism; difficult interactions with authors; and authorship. Some issues were similar to those published about medical editors; however, others were unique. This study can assist authors to better understand some of the ethical issues in publishing, can help editors to view their issues in the context of what others experience, and can assist societies and publishers to work toward avoiding these ethical issues in the future. Professional discussions about ethics in nursing publications should be the subject of ongoing research and scientific inquiry.

    The editors of Revista Clínica Española(Rev Clin Esp) inform on their editorial activity during the last 12 months: (a) Objectives and attainments in 2014, (b) Editorial activity, 2014, and (c) 2013 impact factor. In 2014 we achieved the 5 planned objectives. We have published the 9 programmed issues and 103% of the planned papers according to the usual fixed sections. We emphasize the publication of 29 editorials, 21 of which are signed by prestigious foreign authors. From the first January to the 30th September 2014 we received 421 manuscripts (46.8 manuscripts per month), a slight lower figure to that obtained in 2013 (50.9 manuscripts per month). The acceptance rate of the 404 manuscripts whose editorial process has been concluded was 32.3% (originals, 22.4%). We asked for 315 revisions to 240 reviewers and we received 53.3% revisions in less than two weeks (10.4 days). The mean time to adopt an editorial decision for all manuscripts («accepted»/«rejected») has been 18,3 (less than half than in 2009). For «originals» this figure has dropped from 56,6 days in 2009 to 26.6 days in 2014. The mean time elapsed from manuscript reception to its on-line publication was 103 days. In 2014 the collaboration with the working groups from the Internal Medicine Spanish Foundation (FEMI) has reported 11 published manuscripts. In July 2014 we were informed that the Journal Citation Reports gave Rev Clin Esp an Impact Factor of 1,314 (year 2013). This Impact Factor without self-citations would have been 0.705 (in 2009 the global impact factor was 0,584). With the Editorial Committee farewell we welcome the new editorial team and we sincerely thank the SEMI Steering Committee, our colleagues, journal officers, reviewers, readers and authors that since 2009 have trusted on our editorial work.

    The Editors of the Rev Clin Esp inform herein on their editorial activity in the last year (November 2009 to October 2010) according to three different sections: (a) Objectives and achievements during 2010, (b) editorial activity, and (c) objectives for 2011. During 2010, we have updated the editorial algorithm (manuscript time lag). We have developed the "E-case reports" section and we have linked the abstracts of the Annual Congress of the Spanish Society of Internal Medicine (SEMI) to a journal supplement (electronically available). Since 2010, the subscribers have been able to receive all of the contents of the Rev Clin Esp on-line and to perform self-evaluations in order to obtain 1.7 credits per each journal issue (continuing education). In 2010 we handled 402 manuscripts (7.2% more than in 2009), 35% of which were accepted for publication. We asked 186 reviewers for their expert opinion, 75% of whom sent their reports in less than two weeks. The mean time needed to reach an editorial decision concerning original manuscripts ("accepted / rejected") was 44.5 days and for papers not sent to external reviewers 19.5 days. Collaboration with the work groups produced good results (2.4 published manuscripts per issue), but this could be improved if all the groups collaborated in all the journal sections. Our objectives for 2011 are to complete the renewal of the Rev Clin Esp scientific committee, in accordance with the SEMI Council, and to continue to proceed with the actions initiated to increase the journal impact factor. Rev Clim Esp is an open forum for all internal medicine specialists. Responsibility falls on all of us to collaborate in order to make our journal a little better day by day.

    Background Biological Computer Aided Design (bioCAD) assists the de novo design and selection of existing genetic components to achieve a desired biological activity, as part of an integrated design-build-test cycle. To meet the emerging needs of Synthetic Biology, bioCAD tools must address the increasing prevalence of combinatorial library design, design rule specification, and scar-less multi-part DNA assembly. Results We report the development and deployment of web-based bioCAD software, DeviceEditor, which provides a graphical design environment that mimics the intuitive visual whiteboard design process practiced in biological laboratories. The key innovations of DeviceEditor include visual combinatorial library design, direct integration with scar-less multi-part DNA assembly design automation, and a graphical user interface for the creation and modification of design specification rules. We demonstrate how biological designs are rendered on the DeviceEditor canvas, and we present effective visualizations of genetic component ordering and combinatorial variations within complex designs. Conclusions DeviceEditor liberates researchers from DNA base-pair manipulation, and enables users to create successful prototypes using standardized, functional, and visual abstractions. Open and documented software interfaces support further integration of DeviceEditor with other bioCAD tools and software platforms. DeviceEditor saves researcher time and institutional resources through correct-by-construction design, the automation of tedious tasks, design reuse, and the minimization of DNA assembly costs.

    The editors of scholarly journals have a duty to uphold and promote the highest standards of ethical conduct of research. They also have a responsibility to maintain the integrity of the literature, and to promote transparency and honesty in reporting research findings. In the process of screening manuscripts they receive for possible publication, editors have the obligation to report infractions to the institutions of offending authors, and request an investigation. Since editors can reject a paper on ethical grounds, they can be considered to be the guardians of ethics who should express high ethical standards in conducting and publishing their own research. An examination of several publishers' websites reveals no such requirement or clear selection criteria for journal editors. Therefore, we aim to discuss the factors that publishers, in a broad sense, should consider when selecting editors for scholarly journals and believe that such criteria should be made public to ensure accountability. This would restore some of the eroding public trust in disseminated research, fortify confidence in the composition and qualification of members of an editorial board, and help to protect the reputations of publishers and editors.

    The editors of Revista Clínica Española(Rev Clin Esp) inform on their editorial activity during the last 12 months: (a) objectives and attainments, (b) editorial activity, and (c) objectives for 2014. In 2013 the most relevant modification concerning the editorial activity has been the translation into English of the 5 manuscripts with abstract contained in each issue (http://www.revclinesp.es/). From the first January to the 30th September 2013 we received 458 manuscripts (50.9 manuscripts per month), a similar figure to that obtained in 2012 (51.1 manuscripts per month). The acceptance rate of the 443 manuscripts whose editorial process has been concluded was 23.7% (originals, 11.8%). We asked for 253 revisions to 186 reviewers and we received 74.4% revisions in less than 2 weeks (10.9 days). The mean time to adopt an editorial decision for all manuscripts («accepted»/«rejected») has been 20,3 (half than in 2009). For «originals» this figure has dropped from 56.6 days in 2009 to 22.5 days in 2013. The mean time elapsed from manuscript reception to its on-line publication was 94.8 days in 2013 (110.5 in 2012 and 155.8 in 2011). In 2013 the collaboration with the working groups from the Internal Medicine Spanish Foundation has reported 17 published manuscripts. In 2013 we were informed that the Journal Citation Reports excluded Rev Clin Esp from its impact factor journal list due to its elevated self-citations. We have taken a number of actions to reduce self-citations and we expect to be a minority in 2014. Some other data concerning the editorial policy are encouraging. In this sense, manuscript citation to Rev Clin Esp published articles has seen a substantial increase from 19% in 2008 to 29% in 2012. We work to achieve the digitalization of Rev Clin Esp from 1940 to 1999 (the journal is already digitalized since 2000).

    Dear authors and reviewers of articles for Measurement Science and Technology, I would like to thank all those who have published papers with us in 2010, and special thanks go to those of you who have kindly reviewed articles for the journal. I would also like to take this opportunity to update you on some of the developments on the journal and look ahead to 2011. As many of you are no doubt aware, our impact factor (a measure of the average number of times recent papers are referred to by others) is currently 1.317. This is often taken as an indication of the quality and relevance of recently published research, and although as readers we develop our own instinct for journals of high quality, it is gratifying as an Editor to see the data from an independent organization (Thomson ISI) agreeing with my own assessment. Measurement Science and Technology is a journal with a broad scope covering new measurement techniques in all fields of science and engineering. I therefore find it particularly enjoyable to read summaries of recent research in our strong topical review programme as these cover many varied topics of interest. In 2010 several interesting articles by international leaders in their field were published, for example: Single-photon generation and detection, by G S Buller and R J Collins of Heriot-Watt University [1]. Fluorescence lifetime imaging microscopy in life sciences, by Jan Willem Borst and Antonie J W G Visser, from the Microspectroscopy Centre of Wageningen University [2]. Biological and chemical sensors for cancer diagnosis, by Elfriede Simon of Siemens AG [3]. I hope that these articles, and the others published in 2010 and now in 2011, will provide a useful overview for our readers, and be helpful to new researchers. When speaking to young researchers I am particularly aware that having their articles published in a timely fashion is important, and I am pleased that our publication times are highly competitive, with most authors receiving a

    On September 29th, 2000, The Chilean Association of Biomedical Journal Editors was founded, sponsored by the "Comisión Nacional de Investigación Científica y Tecnológica (CONICYT)" (the Governmental Agency promoting and funding scientific research and technological development in Chile) and the "Sociedad Médica de Santiago" (Chilean Society of Internal Medicine). The Association adopted the goals of the World Association of Medical Editors (WAME) and therefore it will foster "cooperation and communication among Editors of Chilean biomedical journals; to improve editorial standards, to promote professionalism in medical editing through education, self-criticism and self-regulation; and to encourage research on the principles and practice of medical editing". Twenty nine journals covering a closely similar number of different biomedical sciences, medical specialties, veterinary, dentistry and nursing, became Founding Members of the Association. A Governing Board was elected: President: Humberto Reyes, M.D. (Editor, Revista Médica de Chile); Vice-President: Mariano del Sol, M.D. (Editor, Revista Chilena de Anatomía); Secretary: Anna María Prat (CONICYT); Councilors: Manuel Krauskopff, Ph.D. (Editor, Biological Research) and Maritza Rahal, M.D. (Editor, Revista de Otorrinolaringología y Cirugía de Cabeza y Cuello). The Association will organize a Symposium on Biomedical Journal Editing and will spread information stimulating Chilean biomedical journals to become indexed in international databases and in SciELO-Chile, the main Chilean scientific website (www.scielo.cl).

    To begin, I would like to wish our readers, authors, referees and Board of Editors a successful and happy 2008 and thank them for their contributions to Nuclear Fusion in 2007. I took over the editorship of Nuclear Fusion in January, and the year has been one in which the community as a whole has been busier than ever with a variety of duties associated with the ITER project. It was with pride that we published the Progress in the ITER Physics Basis in the June issue of the journal (stacks.iop.org/NF/47/i=6). The task undertaken by the coordinators, authors and referees was a daunting one but one which led to an outstandingly successful issue. The response from readers has been phenomenal and there were in the region of 10 000 downloads of papers in the first month following publication. Looking to 2008 and beyond, the journal will endeavour to continue to support the work of the fusion community. Refereeing As we have done since January 2005, we would like to thank our top ten most loyal referees who have helped the journal with its double-referee peer-review procedure in the past year. At the Nuclear Fusion Editorial Office we are fully aware of the load we put on the shoulders of our referees. At the end of 2004 the Editorial Board decided that a gesture of gratitude should be made to our most loyal referees. We offer them a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. To select the top referees we have adopted the criterion that a researcher should have acted as a referee or adjudicator for at least three different manuscripts during the period from summer 2006 to the end of 2007. We have excluded our Board members and those referees who were already listed in the top ten in the last two years. According to our records the following people met this criterion.

    The introduction for the special issue on open simulation laboratories, the guest editors describe how OSLs will become more common as their potential is better understood and they begin providing access to valuable datasets to much larger segments of the scientific community. Moreover, new analysis tools and ways to do science will inevitably develop as a result.

  1. Are Editors Out of the Tenure Process?

    University presses have complained for years that tenure committees unfairly expect their editors to be arbiters of what counts as tenure-worthy work. At the same time, the presses have been caught in a business-side squeeze between dwindling sales (and shrinking subsidies) and the ever-greater pressure on scholars to publish.

  3. A Visual Editor in Java for View

    NASA Technical Reports Server (NTRS)

    Stansifer, Ryan

    2000-01-01

    In this project we continued the development of a visual editor in the Java programming language to create screens on which to display real-time data. The data comes from the numerous systems monitoring the operation of the space shuttle while on the ground and in space, and from the many tests of subsystems. The data can be displayed on any computer platform running a Java-enabled World Wide Web (WWW) browser and connected to the Internet. Previously a special-purpose program bad been written to display data on emulations of character-based display screens used for many years at NASA. The goal now is to display bit-mapped screens created by a visual editor. We report here on the visual editor that creates the display screens. This project continues the work we bad done previously. Previously we had followed the design of the 'beanbox,' a prototype visual editor created by Sun Microsystems. We abandoned this approach and implemented a prototype using a more direct approach. In addition, our prototype is based on newly released Java 2 graphical user interface (GUI) libraries. The result has been a visually more appealing appearance and a more robust application.

  8. OPM Scheme Editor 2: A graphical editor for specifying object-protocol structures

    SciTech Connect

    Chen, I-Min A.; Markowitz, V.M.; Pang, F.; Ben-Shachar, O.

    1993-07-01

    This document describes an X-window based Schema Editor for the Object-Protocol Model (OPM). OPM is a data model that supports the specification of complex object and protocol classes. objects and protocols are qualified in OPM by attributes that are defined over (associated with) value classes. Connections of object and protocol classes are expressed in OPM via attributes. OPM supports the specification (expansion) of protocols in terms of alternative and sequences of component (sub) protocols. The OPM Schema Editor allows specifying, displaying, modifying, and browsing through OPM schemas. The OPM Schema Editor generates an output file that can be used as input to an OPM schema translation tool that maps OPM schemas into definitions for relational database management systems. The OPM Schema Editor was implemented using C++ and the X11 based Motif toolkit, on Sun SPARCstation under Sun Unix OS 4.1. This document consists of the following parts: (1) A tutorial consisting of seven introductory lessons for the OPM Schema Editor. (2) A reference manual describing all the windows and functions of the OPM Schema Editor. (3) An appendix with an overview of OPM.

  9. NdHO, a novel oxyhydride

    Wideroe, Marius; Fjellvag, Helmer; Norby, Truls; Willy Poulsen, Finn; Willestofte Berg, Rolf

    2011-07-15

    A new metal oxyhydride; neodymium oxyhydride, NdHO, has been synthesized from a reactant mixture of metal hydride (CaH{sub 2} or NdH{sub 3}) and neodymium oxide (Nd{sub 2}O{sub 3}). The unit cell dimensions decrease smoothly in the series from LaHO, CeHO, PrHO to NdHO, in line with the lanthanide contraction. The crystal structure of NdHO is described on the basis of Rietveld refinement on neutron powder diffraction data: Space group: P4/nmm (no. 129, D{sub 4h}{sup 7}). Axis lengths: a=7.8480(5) A, c=5.5601(8) A. Volume: V=342.46(6) A{sup 3}. The tetragonal structure is derived from the fluorite structure, showing complete ordering of hydride and oxide ions over the anion sublatttice. The formation of NdHO was further substantiated by Raman spectroscopy. - Graphical Abstract: View of the NdHO structure. Highlights: > CaH{sub 2} or NdH{sub 3} react with Nd{sub 2}O{sub 3} in reducing atmospheres forming a new oxyhydride, NdHO. > NdHO crystalises in tetragonal space group P4/nmm with axes a=b=7.8480(5) A and c=5.5601(8) A. > The structure is similar to the fluorite structure with complete ordering of hydride and oxide ions. > Unit cell dimensions decrease smoothly in the series from LaHO, CeHO, PrHO to NdHO. > The formation of NdHO is substantiated by Raman spectroscopy.

  12. Evolutionary theory in letters to the editor.

    PubMed

    Silva, Eric Orion; Lowe, Clayton Cory

    2015-05-01

    This research note presents the results of a content analysis of 234 letters to the editors that discuss evolutionary theory and were published in American newspapers. We find that letters to the editor both support and hinder the cause of teaching evolutionary theory in American secondary schools. On the one hand, anti-evolutionary theory messages are marginalized in the letters section. This marginalization signals a low level of legitimacy for creationism. It might also contribute to the sense of tension that sustains creationist identities. On the other hand, relatively few letters explicitly note the fact that scientists or the scientific community accept evolution. Interestingly, the obscuration of the scientific community's support for evolutionary theory occurs both in letters supporting and opposing evolutionary theory.

  14. Workbench surface editor of brain cortical surface

    NASA Astrophysics Data System (ADS)

    Dow, Douglas E.; Nowinski, Wieslaw L.; Serra, Luis

    1996-04-01

    We have developed a 3D reach-in tool to manually reconstruct 3D cortical surface patches from 2D brain atlas images. The first application of our cortex editor is building 3D functional maps, specifically Brodmann's areas. This tool may also be useful in clinical practice to adjust incorrectly mapped atlas regions due to the deforming effect of lesions. The cortex editor allows a domain expert to control the correlation of control points across slices. Correct correlation has been difficult for 3D reconstruction algorithms because the atlas slices are far apart and because of the complex topology of the cortex which differs so much from slice to slice. Also, higher precision of the resulting surfaces is demanded since these define 3D brain atlas features upon which future stereotactic surgery may be based. The cortex editor described in this paper provides a tool suitable for a domain expert to use in defining the 3D surface of a Brodmann's area.

    The high-spin states in 153Ho have been studied by the La57(20Ne139,6 n ) reaction at a projectile energy of 139 MeV at the Variable Energy Cyclotron Centre (VECC), Kolkata, India, utilizing an earlier campaign of the Indian National Gamma Array (INGA) setup. Data from γ -γ coincidence, directional correlation, and polarization measurements have been analyzed to assign and confirm the spins and parities of the levels. We have suggested a few additions and revisions of the reported level scheme of 153Ho. The RF-γ time difference spectra have been useful to confirm the half-life of an isomer in this nucleus. From the comparison of experimental and theoretical results, it is found that there are definite indications of shape coexistence in this nucleus. The experimental and calculated lifetimes of several isomers have been compared to follow the coexistence and evolution of shape with increasing spin.

    From the Board of Editors: on Plagiarism

    Dear Colleagues: There has been a significant increase in the number of duplicate submissions and plagiarism cases reported in all major journals, including the journals of the Optical Society of America. Duplicate submissions and plagiarism can take many forms, and all of them are violations of professional ethics, the copyright agreement that an author signs along with the submission of a paper, and OSA's published Author Guidelines. There must be a significant component of new science for a paper to be publishable. The copying of large segments of text from previously published or in-press papers with only minor cosmetic changes is not acceptable and can lead to the rejection of papers. Duplicate submission: Duplicate submission is the most common ethics violation encountered. Duplicate submission is the submission of substantially similar papers to more than one journal. There is a misperception in a small fraction of the scientific community that duplicate submission is acceptable because it sometimes takes a long time to get a paper reviewed and because one of the papers can be withdrawn at any time. This is a clear violation of professional ethics and of the copyright agreement that is signed on submission. Duplicate submission harms the whole community because editors and reviewers waste their time and in the process compound the time it takes to get a paper reviewed for all authors. In cases of duplicate submission, the Editor of the affected OSA journal will consult with the Editor of the other journal involved to determine the proper course of action. Often that action will be the rejection of both papers. Plagiarism: Plagiarism is a serious breach of ethics and is defined as the substantial replication, without attribution, of significant elements of another document already published by the same or other authors. Two types of plagiarism can occur

    In today's operations environment, the teams are smaller and need to be more efficient while still ensuring the safety and success of the mission. In addition, teams often begin working on a mission in its early development phases and continue on the team through actual operations. For these reasons the operations teams want to be presented with a software environment that integrates multiple needed software applications as well as providing them with context sensitive editing support for entering commands and sequences of commands. At Jet Propulsion Laboratory, the Multi-Mission Planning and Sequencing (MPS) Editor provided by the Multi-Mission Ground Systems and Services (MGSS) supports those operational needs.

    In September 1940, the Journal introduced Out of the Editor's Basket for short items of interest: excerpts from letters, pamphlets, newspapers, and periodicals. By 1950, however, the Editor's Basket had evolved into a bulletin board for descriptions of new products and services, and it now contains almost exclusively press releases about recently marketed items. Now over 60 years old, the Editor's Basket still provides interesting tidbits for the Journal's broad readership.

    Moon, Chang-Bum; Komatsubara, Tetsuro; Furuno, Kohei

    2013-10-01

    The excited states of the odd-odd 154Ho nucleus have been studied by using in-beam γ-ray spectroscopy with the 141Pr (16O, 3n) 154Ho reaction at Elab=75 MeV. The beam was provided by the 12UD Pelletron accelerator at the University of Tsukuba. In this work, the complicated decay pattern of low energy transitions just above the T1/2=3.10 min isomer have been established. In addition, a number of new states and γ-ray transitions, especially those associated with energetically favored band termination, have been observed for the first time in 154Ho. A negative collective band and its signature partner built on the 11- level are interpreted as being based on the πh11/2⊗νi13/2 configuration. A positive band built on the 10+ level is based on the πh11/2⊗νh9/2 configuration while another positive band built on the 9+ level is being associated with the πh11/2⊗νf7/2 configuration. An energetically favored level Jπ=19- can be interpreted as being attributed to the πh11/2⊗νi13/2 configuration coupled to the 8+ state in neighboring core 152Dy, namely, a four-quasiparticle alignment based on the [πh11/2νi13/2]11-⊗[ν(h9/2f7/2)]8- configuration. Another energetically favored state at Jπ=27- is assigned the six-quasiparticle [π(h11/2)3]27/2-⊗[ν(f7/2h9/2i13/2)]27/2- configuration.

  7. Ferroelectricity and competing interactions in Ho-deficient non-stoichiometric orthorhombic HoMnO{sub 3}

    SciTech Connect

    Wang, J. X.; Yan, Z. B.; Xie, Y. L.; Zhou, X. H.; Liu, J.-M.

    2015-05-07

    We investigate the consequences of the Ho-deficient non-stoichiometry in orthorhombic HoMnO{sub 3} in terms of microscopic mechanisms for ferroelectricity modulation. It is suggested that the Ho-deficiency (then Mn excess) results in Ho-vacancies and then Mn occupation of the Ho-site with increasing non-stoichiometry. The Ho-deficiency enhances the Mn-Mn symmetric exchange striction by suppressing the independent Ho-Ho interaction, and thus benefits to the induced Ho spin ordering against the independent Ho spin ordering. The symmetric Ho-Mn exchange striction is thus enhanced by this induced Ho spin ordering, leading to remarkably enhanced ferroelectric polarization as observed. This work presents an alternative scheme to modulate the multiferroicity in rare-earth manganites of strong 4f-3d coupling.

    2012-04-01

    When Professor Anders Bárány took over as the Executive Editor of Physica Scripta, in 1986, he talked of his trepidation at having to 'dress himself' in his predecessor's 'editorial coveralls'. At that time, they had been worn by Professor Nils Robert Nilsson, a major figure in the physics community, for almost 20 years. Just one year prior to this, Professor Roger Wäppling had been recruited to the position of Subeditor in conjunction with a decision to expand the number of contributions in the field of condensed matter physics, to turn it into one of the dominant subjects in the broad-based journal. Physica Scripta had already gained a reputation for being a high quality journal with wide coverage of both experimental and theoretical physics. Interestingly, in the mid 1980s, the number of papers submitted had been growing and an impressive 250 submissions per year had been attained, with all of the manuscripts being handled in-house. Not many miles away in the town of Uppsala, a group of English students was stepping off a train on a magnificent snowy day in January to embark on their final year projects. A couple of us enjoyed ourselves so much that we stayed on afterwards as PhD students, thereby encountering the mixed pleasure of studying physics in a second language for the first time. I used to copy the notes down meticulously in Swedish, then try to work backwards with a textbook to improve my language skills. One day, returning from a particularly incomprehensible lecture on solid state physics, I showed my roommates my notes and asked if they could please explain what the lecture had been about: 'I don't know', they replied, 'but this bit is about sheep!' Meanwhile, back at Physica Scripta, the journal continued to flourish: 400 submissions were received in 1996, and the march of progress was well underway. Manuscripts could now be sent in on disks and Physica Scripta was available on the World Wide Web. Roger was appointed to manage the journal and

  10. Increasing Accuracy and Increasing Tension in Ho

    NASA Astrophysics Data System (ADS)

    Freedman, Wendy L.

    2017-01-01

    The Hubble Constant, Ho, provides a measure of the current expansion rate of the universe. In recent decades, there has been a huge increase in the accuracy with which extragalactic distances, and hence Ho, can be measured. While the historical factor-of-two uncertainty in Ho has been resolved, a new discrepancy has arisen between the values of Ho measured in the local universe, and that estimated from cosmic microwave background measurements, assuming a Lambda cold dark matter model. I will review the advances that have led to the increase in accuracy in measurements of Ho, as well as describe exciting future prospects with the James Webb Space Telescope (JWST) and Gaia, which will make it feasible to measure extragalactic distances at percent-level accuracy in the next decade.

    Richman, Barbara T.

    ‘I want the journal to acquire a reputation for very rapid, fair, and accurate reviewing,’ asserted John F. Dewey, editor-in-chief of AGU's newest journal, Tectonics. Dewey said that he will rule the bimonthly, which will begin publication in February, ‘with a bit of a rod of iron’ to ensure that Tectonics is ‘where only original and important papers are published.’‘I'm going to be very strict with reviewers,’ Dewey explained in his quick British clip. ‘If the review does not come back to me within 10 days to 2 weeks, I'll review the paper myself. I'm also going to have a system whereby, if a paper needs major surgery after being refereed, it will be rejected. Papers will have to be in virtually publishable condition before they are first submitted,’ he said.

  12. A former Editor views the editorial process

    NASA Astrophysics Data System (ADS)

    Freeze, R. Allan

    It was at the AGU Fall Meeting in San Francisco in December 1976, shortly after my appointment as coeditor of Water Resources Research that I first began to realize the strong emotional ties that exist between a scientific community and its journals. Feelings run high, regardless of whether they come from readers, contributors, reviewers, active scientists, or scientific administrators. Opinions are often positive, sometimes negative, usually a mixture of the two; but regardless of their tenor they are delivered to the editor, in person, usually fortissimo.

  1. Thermochemistry of HO2 + HO2 → H2O4: Does HO2 Dimerization Affect Laboratory Studies?

    PubMed

    Sprague, Matthew K; Irikura, Karl K

    2015-07-09

    Self-reaction is an important sink for the hydroperoxy radical (HO2) in the atmosphere. It has been suggested (Denis, P. A.; Ornellas, F. R. J. Phys. Chem. A, 2009, 113 (2), 499-506) that the minor product hydrogen tetroxide (HO4H) may act as a reservoir of HO2. Here, we compute the thermochemistry of HO2 self-reactions to determine if either HO4H or the cyclic hydrogen-bound dimer (HO2)2 can act as reservoirs. We computed electronic energies using coupled-cluster calculations in the complete basis set limit, CCSD(T)/CBS[45]//CCSD(T)/cc-pVTZ. Our model chemistry includes corrections for vibrational anharmonicity in the zero-point energy and vibrational partition functions, core-valence correlation, scalar relativistic effects, diagonal Born-Oppenheimer, spin-orbit splitting, and higher-order corrections. We compute the Gibbs energy of dimerization to be (-20.1 ± 1.6) kJ/mol at 298.15 K (2σ uncertainty), and (-32.3 ± 1.5) kJ/mol at 220 K. For atmospherically relevant [HO2] = 10(8) molecules per cm(3), our thermochemistry indicates that dimerization will be negligible, and thus H2O4 species are atmospherically unimportant. Under conditions used in laboratory experiments ([HO2] > 10(12) molecules per cm(3), 220 K), H2O4 formation may be significant. We compute two absorption spectra that could be used for laboratory detection of HO4H: the OH stretch overtone (near-IR) and electronic (UV) spectra.

  2. Theoretical Studies of the HO/HO2 Catalytic Cycle for Ozone Destruction

    NASA Technical Reports Server (NTRS)

    Walch, Stephen P.; Langhoff, Steve R. (Technical Monitor)

    1996-01-01

    Recently it has been determined that the HO/HO2 catalytic cycle accounts for nearly one-half of the total ozone depletion in the lower stratosphere. The catalytic cycle is: (1) HO + O3 yields HO2 + O2; (2) HO2 + O3 yields HO + O2 + O2. The net reaction is 2O3 yields 3O2. The rate limiting step in this process is the reaction of HO2 with ozone. There is a problem extending the experimental measurement of the rate of this reaction over the range 233-400 K down to stratospheric temperatures of 210-220 K. Therefore we have undertaken a project to determine the temperature dependence of the rate constant for this reaction in the low temperature region. The first step in this project, which is described in this poster, is the determination of the relevant potential energy surfaces. The calculations use CASSCF/derivative methods to define the pathways followed by CASSCF/ACPF to determine the energetics. The HO + O3 reaction is found to proceed through an HO4 complex, which is unstable with respect to HO2 + O2. The HO2 +O3 reaction is more complex. One pathway, which has been characterized, is the formation of an HO5 complex which decomposes to HO3 + O2 and subsequently to HO + O2 + O2. Another pathway, which is believed to also play a role, is hydrogen abstraction to give O2 + HO3 and subsequent decomposition of HO3 to HO + O2. Isotopic labeling experiments indicate that the later pathway is dominant. However, so far attempts to locate the saddle point for this pathway have not been successful. We have also characterized the potential energy surfaces for a number of species involved in these reactions, including HO3 and triplet O4. The triplet O4 species is probably involved in the reaction of vibrationally excited O2 with ground state O2 leading to O3 + O. The latter reaction is believed to be important as an additional source of stratospheric ozone.

    2013-01-01

    A molecule editor, i.e. a program facilitating graphical input and interactive editing of molecules, is an indispensable part of every cheminformatics or molecular processing system. Today, when a web browser has become the universal scientific user interface, a tool to edit molecules directly within the web browser is essential. One of the most popular tools for molecular structure input on the web is the JME applet. Since its release nearly 15 years ago, however the web environment has changed and Java applets are facing increasing implementation hurdles due to their maintenance and support requirements, as well as security issues. This prompted us to update the JME editor and port it to a modern Internet programming language - JavaScript. The actual molecule editing Java code of the JME editor was translated into JavaScript with help of the Google Web Toolkit compiler and a custom library that emulates a subset of the GUI features of the Java runtime environment. In this process, the editor was enhanced by additional functionalities including a substituent menu, copy/paste, drag and drop and undo/redo capabilities and an integrated help. In addition to desktop computers, the editor supports molecule editing on touch devices, including iPhone, iPad and Android phones and tablets. In analogy to JME the new editor is named JSME. This new molecule editor is compact, easy to use and easy to incorporate into web pages. A free molecule editor written in JavaScript was developed and is released under the terms of permissive BSD license. The editor is compatible with JME, has practically the same user interface as well as the web application programming interface. The JSME editor is available for download from the project web page http://peter-ertl.com/jsme/

    There is considerable gender disparity in editorial boards of medical journals. Being an editor in a Cochrane review group (CRG), like being an editor in a medical journal, is an indirect representation of one's reputation and leadership abilities in a particular specialty. The aim of the study was to analyze the representation of women editors on the editorial teams of CRG's and the Central Editorial Unit (CEU) of the Cochrane Collaboration. Information about editorial team members of CRGs and the CEU was extracted from respective websites. Gender of the individual was determined by inspection of names, individual profile description or photographs in the CRG or institutional webpage, social networking sites and internet search. Data was validated by two authors independently and differences sorted by consensus. A total of 788 editors across all CRGs and the CEU with an overall 371 females (47.1%) and 417 (52.9%) males were identified. of the CEU editors, 62.5% were females. There were 68 coordinating editors (35.3% females), and 62 managing editors (56% females), who provided leadership to the CRGs. Eighty-four percent of trial search coordinators were found to be females. Ten CRGs had 75% or more of its editors as females while 7 CRGs had less than or equal to 25% female editors. The representation of women editors in the Cochrane Collaboration was found to be better than in editorial boards of medical journals. There is still scope for improvement to ensure better gender diversity across all roles and in all CRG's. © 2014 Chinese Cochrane Center, West China Hospital of Sichuan University and Wiley Publishing Asia Pty Ltd.

Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from socialism as found in the real world (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal.Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality

    A Ho:YLF laser pumped HBr molecular laser was developed that produced up to 2.5 mJ of energy in the 4 micron wavelength region. The Ho:YLF laser was fiber pumped using a commercial Tm:fibre laser. The Ho:YLF laser was operated in a single longitudinal mode via injection seeding with a narrow band diode laser which in turn was locked to one of the HBr transitions. The behavior of the HBr laser was described using a rate equation mathematical model and this was solved numerically. Good agreement both qualitatively and quantitatively between the model and experimental results was obtained.

    ESDAPT is a graphical programming environment for developing APT (Automatically Programmed Tool) programs for controlling numerically controlled machine tools. ESDAPT has a graphical user interface that provides the user with an APT syntax sensitive text editor and windows for displaying geometry and tool paths. APT geometry statement can also be created using menus and screen picks. ESDAPT interprets APT geometry statements and displays the results in its view windows. Tool paths are generated by batching the APT source to an APT processor (COSMIC P-APT recommended). The tool paths are then displayed in the view windows. Hardcopy output of the view windows is in color PostScript format. ESDAPT is written in C-language, yacc, lex, and XView for use on Sun4 series computers running SunOS. ESDAPT requires 4Mb of disk space, 7Mb of RAM, and MIT's X Window System, Version 11 Release 4, or OpenWindows version 3 for execution. Program documentation in PostScript format and an executable for OpenWindows version 3 are provided on the distribution media. The standard distribution medium for ESDAPT is a .25 inch streaming magnetic tape cartridge (Sun QIC-24) in UNIX tar format. This program was developed in 1992.

    1994-01-01

    In March of 1992 a workshop sponsored by NASA and NSF was held at SRI International to assess the current ability to measure atmospheric OH and HO2. The measurement techniques reviewed during the workshop for detection of OH included five laser-induced fluorescence schemes, five laser-based adsorption techniques, and four non-laser methods. Six instruments or instrument concepts for HO2 detection, including chemical amplification, conversion to OH with subsequent OH detection, or direct spectroscopic detection of the HO2 were also discussed. The conclusions from the workshop identify several measurement techniques for OH and HO2 that are ready for field tests. These have the ability to measure the radicals with sufficient sensitivity and accuracy to form meaningful comparison with atmospheric model predictions. The workshop conclusions also include recommendations for informal and formal intercomparison protocols.

  20. EDITORIAL: Incoming Editor-in-Chief

    NASA Astrophysics Data System (ADS)

    Webb, Steve

    2006-01-01

    Physics in Medicine and Biology (PMB) is a journal that originated in the UK but is now rightly regarded as one of the pre-eminent international journals for the publication of material coming within its remit. It is 50 years old and its maturity is an outcome of the consistent support of high performing authors, a supportive and professional publishing house, dedicated referees, many vigorous and conscientious editorial boards and the collective input of the 10 previous Editors as listed in his incoming editorial (January 2000 issue) by the retiring Editor, Professor Alun Beddoe. The scientific climate and it associated publication modus operandi in the 1950s was very different from that at the current time and the journal has evolved to reflect this. Hence today the scope of content is somewhat broader, the size of the journal is vastly greater, the whole publication process is slicker and more efficient and a paper in PMB is highly prized by its authors and those who look to quality factors and impact. The quality of the journal still relies on the voluntary labour and expertise of its busy international referees and Board members. For many years I have tried to place my own research material in PMB and encourage my teams to do likewise, not only acknowledging the prestige of the journal but also because of the extraordinarily fast turnaround time of all the processes without any loss of quality. This serves us very well and the publishing team are to be congratulated. Some things seem to change more slowly or not at all, however. The prediction, when I started my research career, that books and journals would be dinosaurs by now has manifestly not come true and, whilst most of us are addicted (and why not?) to the electronic ways of doing things that can be done by more traditional ways, PMB and a packet of reprints from time to time arriving by post still has a reassuring feel despite the fact that the papers have been `on-line' for a while before.

  1. Editorial independence and the editor-owner relationship: good editors never die, they just cross the line.

    PubMed

    Lapeña, J F

    2009-12-01

    The concept of editorial freedom or independence is examined in the light of the editor-owner relationship. Like individual and national freedom or independence, it is a rhetorical concept whose realisation flows from internal achievement as much as it depends on external validation. This freedom entails roles and responsibilities embodied in specific codes of practice for editors, such as the guidelines espoused by the International Committee of Medical Journal Editors and the World Association of Medical Editors. The calling to embody these guidelines makes editing a vocation that demands isolation and distancing, separation and solitude. It involves bracketing one's biases, prejudgments and preconceptions. With such detachment comes real freedom; one that requires a moral fibre and trustworthiness that uphold truth and right, whether in full view of public scrutiny, or in the aloneness of private secrecy. The stereotypical tension between academic and commercial concerns highlights the editor-owner relationship, and bears directly on editorial independence. In practice, journal owners overstep their prerogatives. The absence of clear contracts defining editorial independence and the lack of established mechanisms governing the editor-owner relationship affect many small- to medium-sized journals in developing countries. Even large journals in developed and democratic nations or totalitarian states and societies are not spared. At the end of the day, editorial freedom exists only insofar as it is tolerated, or until editors cross the line.

  2. HO-1 expression control in the rat glomerulus.

    PubMed

    Detsika, Maria G; Duann, Pu; Lianos, Elias A

    2015-05-08

    The differential localization of HO-1 in renal cells under conditions of injury, and the demonstration that exaggerated HO-1 expression can have detrimental rather than beneficial effects, raises the question of whether HO-1 expression in these cells is subject to control. The present study identifies a unique HO-1 expression pattern in the renal glomerulus indicative of presence of HO-1 expression control following prolonged HO-1 induction. HO-1 and HO-2 expression in response to the natural HO substrate/inducer Fe(++) protoporphyrin (PP) IX (hemin) was assessed in normal rat glomeruli. Following 18 h incubations with hemin (0-200 μM), HO-1 expression increased in a concentration-dependent manner and via a hemopexin (HPX) independent mechanism with no effect on HO-2. In incubations with higher hemin concentrations (400 μM), likely to be encountered in hemolytic disorders, HO-1 expression, decreased. This was preceded by a prolonged and sustained increase in HO-1 protein and was independent of the Fe(++) moiety as incubations with Cobalt protoporphyrin (CoPP) resulted in an identical expression pattern. The decrease of HO-1 protein could not be accounted for by proteasomal degradation since it was not reversed in co-incubations with hemin and the proteasome inhibitor, MG132, at concentrations sufficient to increase HO-1 glomerular content when used alone. Moreover, in the presence of MG132, a decrease of HO-1 expression also occurred at 100 and 200 μM hemin. The effect of MG132 was mimicked by two additional mechanistically different approaches which also raised HO-1 content: a) co-incubations of hemin with ZnPP which increased HO-1 protein when used alone, and b) glomerular HO-1 over expression achieved by SB transposon mediated transgenesis. In contrast, the decrease in HO-1 levels observed at high hemin concentrations was reversed in co-incubations with hemin and SnPP, which reduced HO-1 content when used alone.

    Wäppling, Roger; Williams, Sarah

    2006-01-01

    Physica Scripta is an international physics journal published for the Royal Swedish Academy of Sciences on behalf of the Nordic Science Academies and Physical Societies. This issue marks the beginning of the partnership between the Royal Swedish Academy of Sciences and Institute of Physics Publishing (IOP). We look forward to a fruitful relationship in which Physica Scripta can profit from the international reach of IOP. Authors and readers will benefit from advance publication of articles on the web prior to receiving each month's journal issue. The peer-review system will continue to be managed by Professor Roger Wäppling who will assess each paper before assigning it to an external editor or sending it for refereeing. IOP will receive new article submissions and generate electronic documents suitable for use in the refereeing process. The editorial office in Sweden will then be responsible for these manuscripts up to the final publication decision. Accepted articles will be sent to IOP for copy-editing, typesetting, production and distribution. We aim to provide our authors, referees and readers with an enhanced service for this well-established journal. IOP will maintain and augment Physica Scripta's record in publishing a broad range of high-quality research papers and we will continue to publish Topical Issues as supplements to the regular 12 issues. The popular Comments articles will continue to be published in conjunction with regular papers under this new partnership. We hope that our subscribers will continue to enjoy reading Physica Scripta as a valuable resource for general physics research.

  6. EDITORIAL: A Message from the Editor

    1981-04-01

    As the new Editor of Metrologia, I welcome this opportunity to greet the readers, to say a few words on hopes and plans, and to make both a plea and promise. The plea arises from a perception that, despite its sixteen years of existence, this journal does not yet enjoy a status of intimate familiarity throughout the world community of physicists. Nevertheless, having been established as a vehicle for disseminating knowledge on all matters metrological, it offers a unique communication and archival resource to those who are active in advancing the science (and the art) of accurate measurement. Therefore I beseech all readers to lose no opportunity to submit their finest metrology research reports and their most penetrating metrological ruminations for publication here and—highly important—to encourage their unaware colleagues to do likewise. And, as a journal cannot flourish which is not fully responsive to the needs of its clientele, my promise is to bend every effort to achieving prompt and careful review of your submissions and rapid publication for those accepted. It is my hope and intention, furthermore, to bring about a measure of increased variety of content through occasional seminal review articles, news of major publications and forthcoming conferences, news of current research and development that should be of major interest to the readership well before the publication of its results; and through the inclusion of short communications on research, letters and topics of wide interest, and comments on articles published. In order to successfully promote these aims, your specific contributions and your suggestions for improvements are enthusiastically solicited. Finally, let me record my gratitude to the distinguished scientists who have agreed to serve for a term on the Editorial Board, to assist me in my task and to labour in the interests of you all. Each member of that Board stands ready to assist the readership on any matter pertaining to

    Every year hundreds of thesis reports are completed by graduate students. Many of these end up on nursing journal editors' desks, only to be rejected. What characteristics of a thesis lead to rejection? How can authors develop quality research manuscripts? How can faculty teach graduate students the difference between a thesis and manuscript. This article answers these questions by providing advice from 15 critical care and research journal editors.

    The ZED editor for the DEC VAX is a simple, yet powerful line editor for text, program source code, and non-binary data. Line editors can be superior to screen editors in some cases, such as executing complex multiple or conditional commands, or editing via slow modem lines. ZED excels in the area of text processing by using procedure files. For example, such procedures can reformat a file of addresses or remove all comment lines from a FORTRAN program. In addition to command files, ZED also features versatile search qualifiers, global changes, conditionals, on-line help, hexadecimal mode, space compression, looping, logical combinations of search strings, journaling, visible control characters, and automatic detabbing. The ZED editor was originally developed at Cambridge University in London and has been continuously enhanced since 1976. Users of the Cambridge implementation have devised such elaborate ZED procedures as chess games, calculators, and programs for evaluating Pi. This implementation of ZED strives to maintain the characteristics of the Cambridge editor. A complete ZED manual is included on the tape. ZED is written entirely in C for either batch or interactive execution on the DEC VAX under VMS 4.X and requires 80,896 bytes of memory. This program was released in 1988 and updated in 1989.

    Heme oxygenase-1 (HO-1), the inducible isoform of heme oxygenase (HO), has raised a lot of concerns in recent years due to its multiple functions. HO-1 was found to be a pivotal cytoprotective, antioxidant, anti-apoptotic, immunosuppressive, as well as anti-inflammatory molecule. Recent studies have clarified its significant functions in many diseases with substantial findings. In autoimmune diseases, HO-1 may have promising therapeutic potential. Here, we briefly reviewed recent advances in this field, aiming at hopefully exploring the potential therapeutic roles of HO-1, and design HO-1-based strategies for the treatment of autoimmune diseases.

    In this study, the human absorbed dose of holmium-166 ((166)Ho)-pamidronate (PAM) as a potential agent for the management of multiple myeloma was estimated. (166)Ho-PAM complex was prepared at optimized conditions and injected into the rats. The equivalent and effective absorbed doses to human organs after injection of the complex were estimated by radiation-absorbed dose assessment resource and methods proposed by Sparks et al based on rat data. The red marrow to other organ absorbed dose ratios were compared with these data for (166)Ho-DOTMP, as the only clinically used (166)Ho bone marrow ablative agent, and (166)Ho-TTHMP. The highest absorbed dose amounts are observed in the bone surface and bone marrow with 1.11 and 0.903 mGy MBq(-1), respectively. Most other organs would receive approximately insignificant absorbed dose. While (166)Ho-PAM demonstrated a higher red marrow to total body absorbed dose ratio than (166)Ho-1,4,7,10-tetraazacyclo dodecane-1,4,7,10 tetra ethylene phosphonic acid (DOTMP) and (166)Ho-triethylene tetramine hexa (methylene phosphonic acid) (TTHMP), the red marrow to most organ absorbed dose ratios for (166)Ho-TTHMP and (166)Ho-PAM are much higher than the ratios for (166)Ho-DOTMP. The result showed that (166)Ho-PAM has significant characteristics than (166)Ho-DOTMP and therefore, this complex can be considered as a good agent for bone marrow ablative therapy. In this work, two separate points have been investigated: (1) human absorbed dose of (166)Ho-PAM, as a potential bone marrow ablative agent, has been estimated; and (2) the complex has been compared with (166)Ho-DOTMP, as the only clinically used bone marrow ablative radiopharmaceutical, showing significant characteristics.

    It is a pleasure and an honour for me to be taking over as Editor-in-Chief of Measurement Science and Technology. MST is well known across research communities worldwide as a leading journal in which to publish new techniques and instrumentation. It has gained this enviable position largely because of the excellent guidance of its Editorial Board and dedicated staff at Institute of Physics Publishing over many years. I want to highlight in particular the contribution of the outgoing Editor Peter Hauptmann, and other Editors before him, in making the journal truly international. We thank Peter immensely for all his hard work in leading the journal, having exceptionally served two terms, each of five years. I come into the post of Editor at a very interesting and challenging time for research. The global recession is leading to cuts in research funding in many countries, researchers and their outputs are coming under closer scrutiny than ever before, and more is being expected of them. Journals play a critical role in monitoring and maintaining research standards, but we should be careful not to assume that journal Impact Factor is the sole measure of research quality. Although expediency may sometimes demand it, Impact Factor, as practitioners know, is subject dependent. One of the great things about science and technology for me is its level playing field. The key point is still innovation no matter where the work is done or where it is published. MST has a long pedigree of being the natural home of the highest quality papers from leading researchers wishing to report novel instrumentation and techniques. 2013 will mark the 90th anniversary of MST and we look forward to celebrating in style its sustained success. I recall with pride the first paper I published in Journal of Physics E: Scientific Instruments (as MST was previously titled) back in 1977. The paper reported the design and application of an early fluorescence lifetime spectrometer that I had constructed

    A prototype of Er:Tm:Ho:LiYF4 (Ho:YLF) laser, emitting at 2,065 micrometers , 1,25 J 5 Hz, with pulsewidth of 250 microsecond(s) was developed for biomedical applications. In order to verify the possibility of using this laser for cavities preparation in vivo, temperature rise in the pulp chamber must be known. Temperature changes were measured during Ho:YLF irradiation with 500 mJ/pulse, 30 pulses/position with energy density of 2079 J/cm2/pulse. Two groups of teeth were used: group I with pulp chamber empty and group II with pulp chamber filled with phase change material. In both cases, there were no temperature rise above 3,8 degree(s)C in the pulp chamber.

    Transient absorption spectra and decay profiles of HO2 have been measured using cw near-IR two-tone frequency modulation absorption spectroscopy at 297 K and 50 Torr in diluent of N2 in the presence of water. From the depletion of the HO2 absorption peak area following the addition of water, the equilibrium constant of the reaction HO2 + H2O <--> HO2-H2O was determined to be K2 = (5.2 +/- 3.2) x 10(-19) cm3 molecule(-1) at 297 K. Substituting K2 into the water dependence of the HO2 decay rate, the rate coefficient of the reaction HO2 + HO2-H2O was estimated to be (1.5 +/- 0.1) x 10(-11) cm3 molecule(-1) s(-1) at 297 K and 50 Torr with N2 as the diluent. This reaction is much faster than the HO2 self-reaction without water. It is suggested that the apparent rate of the HO2 self-reaction is enhanced by the formation of the HO2-H2O complex and its subsequent reaction. Results are discussed with respect to the kinetics and atmospheric chemistry of the HO2-H2O complex. At 297 K and 50% humidity, the concentration ratio of [HO2-H2O]/[HO2] was estimated from the value of K2 to be 0.19 +/- 0.11.

  20. Chemistry of HO x radicals in the upper troposphere

    NASA Astrophysics Data System (ADS)

    Jaeglé, Lyatt; Jacob, Daniel J.; Brune, William H.; Wennberg, Paul O.

    Aircraft observations from three recent missions (STRAT, SUCCESS, SONEX) are synthesized into a theoretical analysis of the factors controlling the concentrations of HO x radicals (HO x=OH+peroxy) and the larger reservoir family HO y (HO y=HO x+2H 2O 2+2CH 3OOH+HNO 2+HNO 4) in the upper troposphere. Photochemical model calculations capture 66% of the variance of observed HO x concentrations. Two master variables are found to determine the variance of the 24 h average HO x concentrations: the primary HO x production rate, P(HO x), and the concentration of nitrogen oxide radicals (NO x=NO+NO 2). We use these two variables as a coordinate system to diagnose the photochemistry of the upper troposphere and map the different chemical regimes. Primary HO x production is dominated by the O( 1D)+H 2O reaction when [H 2O]>100 ppmv, and by photolysis of acetone (and possibly other convected HO x precursors) under drier conditions. For the principally northern midlatitude conditions sampled by the aircraft missions, the HO x yield from acetone photolysis ranges from 2 to 3. Methane oxidation amplifies the primary HO x source by a factor of 1.1-1.9. Chemical cycling within the HO x family has a chain length of 2.5-7, while cycling between the HO x family and its HO y reservoirs has a chain length of 1.6-2.2. The number of ozone molecules produced per HO y molecule consumed ranges from 4 to 12, such that ozone production rates vary between 0.3 and 5 ppbv d -1 in the upper troposphere. Three chemical regimes (NO x-limited, transition, NO x-saturated) are identified to describe the dependence of HO x concentrations and ozone production rates on the two master variables P(HO x) and [NO x]. Simplified analytical expressions are derived to express these dependences as power laws for each regime. By applying an eigenlifetime analysis to the HO x-NO x-O 3 chemical system, we find that the decay of a perturbation to HO y in the upper troposphere (as from deep convection) is represented

    1985-01-01

    The SAGA editor provides a mechanism by which separate processes can be invoked during an editing session to traverse portions of the parse tree being edited. These processes, termed filter processes, read, analyze, and possibly transform the parse tree, returning the result to the editor. By defining new commands with the editor's user defined command facility, which invoke filter processes, authors of filter can provide complex operations as simple commands. A tree plotter, pretty printer, and Pascal tree transformation program were already written using this facility. The filter processes are introduced, parse tree structure is described and the library interface made available to the programmer. Also discussed is how to compile and run filter processes. Examples are presented to illustrate aspect of each of these areas.

    To support evolution of domain expertise, and its representation in an expert system knowledge base, a user-friendly rule base editor is mandatory. The Nickel Cadmium Battery Expert System (NICBES), a prototype of an expert system for the Hubble Space Telescope power storage management system, does not provide such an editor. In the following, a description of a Simple Interactive Rule Base Editor (SIRE) for NICBES is described. The SIRE provides a consistent internal representation of the NICBES knowledge base. It supports knowledge presentation and provides a user-friendly and code language independent medium for rule addition and modification. The SIRE is integrated with NICBES via an interface module. This module provides translation of the internal representation to Prolog-type rules (Horn clauses), latter rule assertion, and a simple mechanism for rule selection for its Prolog inference engine.

    Seth A. Stein, one of the editors of the Journal of Geophysical Research—Solid Earth and Planets, says that his approach to editing the journal is based on the premise that authors, reviewers, and editors are all drawn from the same community: the journal's readers. “We all want JGR to publish interesting papers of the highest possible quality. Each of us believes that the papers we review are improved by our comments. It follows, although it is a little harder for most of us to accept, that our own papers generally contain better science and are more useful to readers as a result of reviews,” Stein told Eos.Stein, an associate professor of geological sciences at Northwestern University (Evanston, Ill.), is one of the seven editors of JGR—Solid Earth and Planets for 1987 and 1988 (see box). His specialties are tectonophysics and seismology.

    Scientific editors are responsible for deciding which articles to publish in their journals. However, we have not found documentation of their required knowledge, skills, and characteristics, or the existence of any formal core competencies for this role. We describe the development of a minimum set of core competencies for scientific editors of biomedical journals. The 14 key core competencies are divided into three major areas, and each competency has a list of associated elements or descriptions of more specific knowledge, skills, and characteristics that contribute to its fulfillment. We believe that these core competencies are a baseline of the knowledge, skills, and characteristics needed to perform competently the duties of a scientific editor at a biomedical journal.

  7. LETTER TO THE EDITOR: Dynamical crossover in 'hot' spin ice

    Ehlers, G.; Cornelius, A. L.; Orendác, M.; Kajnaková, M.; Fennell, T.; Bramwell, S. T.; Gardner, J. S.

    2003-01-01

    The magnetic dynamics of the spin ice material Ho2Ti2O7 in its paramagnetic ('hot') phase have been investigated by a combination of neutron spin echo and ac-susceptibility techniques. Relaxation at high temperatures (T > 15 K) is proved to occur by a thermally activated single-ion process that is distinct from the process that dominates at lower temperatures (1 K < T < 15 K). It is argued that the low-temperature process must involve quantum mechanical spin tunnelling, as quasi-classical channels of relaxation are exhausted in this temperature range. Our results resolve a mystery in the physics of spin ice: why has a 15 K ac-susceptibility peak been observed in Dy2Ti2O7 but not in Ho2Ti2O7 or Ho2Sn2O7?

    The flash photolysis/ultraviolet absorption technique was used to measure the rate constants for the reaction HO2 + NO2 + M yields HO2NO2 + M over the pressure range 50-700 torr and temperature range 229-362 K using He, O2, and N2 as diluent gases. The data were fit to the expression derived by Troe (1979) and co-workers for describing the pressure and temperature dependence of reactions in the falloff region. By combining these data with recent measurements of the rate constant for HO2NO2 thermal decomposition values of 73.8 + or - 2 eu for the standard entropy and -12.6 + or - kcal/mol for the standard enthalpy of formation of HO2NO2 were obtained. A significant enhancement in the rate constant was observed when water vapor was added to the system.

    The advent of sophisticated function-key-driven programs for handling text on a video-display terminal enables the editorial staff of a publications department to take an active role on a computerized text-management team, along with compositors and other keyboard operators. Although there are still many things that editors cannot do on a computer terminal, the bulk of manipulating straight text can be speeded, and the problems of rekeyboarding and interpretation of editorial markings can be largely bypassed. The computer also gives editors new tools that open the way for greater control over both the editorial process and the quality of technical publishing. 5 figures.

    Absorption bands at 1259 and 1142 cm-1 in H2O-O2 ice mixtures irradiated with 0.8 MeV protons at 9 K, have been assigned to the HO3 and HO2 radicals respectively. The assignment of these bands is based upon isotopic shift measurements when 18O2 is used. These bands are also observed in irradiated H2O-O3 and pure H2O2 ices. In each case, they are formed by the following reactions: H + O3 → HO3 H + O2 → HO2 While neither radical has been observed in ice using infrared spectroscopy before, the HO2 radical is known to form in irradiated water ice, but remarkably, the lesser known HO3 is the more prominent spectral feature. These species are probably formed in the surfaces of icy outer solar system bodies where O2 and O3 have already been observed. Their ability to remain trapped in ice is unknown and their reactivity at typical surface temperatures may prevent signficant concentrations being produced. However, even as intermediate species, due to their reactivity they may constitute an important component of the oxidant population in such ices. If they can remain trapped, they may provide a potential energy source for organic reactions or even microbial life in places such as Europa's sub-surface ocean.

    Reactions of HO2 radicals with organics are in general assumed to be quite slow. However, it has been known for a number of years that HO2 adds reversibly to HCHO, in a reaction which can lead to the production of formic acid, particularly at low temperature. We have studied the reaction of HO2 with a number of carbonyls as a function of temperature using both time resolved diode laser absorption and FTIR analysis. In the time resolved studies, HO2 is produced by flash photolysis and detected in the overtone of the OH stretching mode by diode laser spectroscopy. The self reaction of HO2 was first studied as a function of temperature and added complexing gases (H2O, CH3OH). The rate coefficient of the self reaction was found to have a moderate negative temperature dependence, in agreement with older studies of this reaction. The addition of carbonyls (HCHO, CH3CHO, CF3CHO, acetone) led to an increase in the loss rate of HO2, enabling kinetic and thermodynamic information to be obtained about the equilibria. Complementary experiments were conducted to examine the products in an environmental chamber using FTIR detection of reactants and products. The reaction mechanisms and environmental impacts of the results will be discussed.

    The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship - emphasizing the importance of responsibility and accountability -, have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors' Network of the European Society of Cardiology.

  1. Ethical dilemmas in scientific publication: pitfalls and solutions for editors.

    PubMed

    Gollogly, Laragh; Momen, Hooman

    2006-08-01

    Editors of scientific journals need to be conversant with the mechanisms by which scientific misconduct is amplified by publication practices. This paper provides definitions, ways to document the extent of the problem, and examples of editorial attempts to counter fraud. Fabrication, falsification, duplication, ghost authorship, gift authorship, lack of ethics approval, non-disclosure, 'salami' publication, conflicts of interest, auto-citation, duplicate submission, duplicate publications, and plagiarism are common problems. Editorial misconduct includes failure to observe due process, undue delay in reaching decisions and communicating these to authors, inappropriate review procedures, and confounding a journal's content with its advertising or promotional potential. Editors also can be admonished by their peers for failure to investigate suspected misconduct, failure to retract when indicated, and failure to abide voluntarily by the six main sources of relevant international guidelines on research, its reporting and editorial practice. Editors are in a good position to promulgate reasonable standards of practice, and can start by using consensus guidelines on publication ethics to state explicitly how their journals function. Reviewers, editors, authors and readers all then have a better chance to understand, and abide by, the rules of publishing.

    This study determined the involvement of women as first authors and other authors for every article published in Experimental and Clinical Psychopharmacology, Pharmacology Biochemistry and Behavior, and Psychopharmacology in 1991, 1996, 2001, and 2006. Their involvement as editors also was determined. Women's participation as authors, but not as editors, slightly increased over time. In 2006, 43% of first authors, 38% of other authors, and 24% of editors were women. The gender of subjects was examined for the same years and journals, but could not be determined for 6% and 9% of articles employing nonhuman and human subjects, respectively. In 2006, when subjects' gender could be determined, 77% of articles involving nonhuman subjects used only males, 9% only females, and 14% both males and females. In articles using human subjects in that same year, 17% involved only males, 6% only females, and 77% both males and females. Women researchers clearly make substantial contributions to the psychopharmacology literature, but are nonetheless underrepresented as editors. Findings regarding subjects indicate that there is growing recognition of the importance of gender as a determinant of drug effects, although the vast majority of nonhuman studies continue to involve only male subjects.

  18. HO-1/CO system in tumor growth, angiogenesis and metabolism - Targeting HO-1 as an anti-tumor therapy.

    2015-11-01

    Heme oxygenase-1 (HO-1, hmox-1) catalyzes the rate-limiting step in the heme degradation processes. Out of three by-products of HO-1 activity, biliverdin, iron ions and carbon monoxide (CO), the latter was mostly shown to mediate many beneficial HO-1 effects, including protection against oxidative injury, regulation of apoptosis, modulation of inflammation as well as contribution to angiogenesis. Mounting evidence suggests that HO-1/CO systemmay be of special benefit in protection inmany pathological conditions, like atherosclerosis or myocardial infarction. By contrast, the augmented expression of HO-1 in tumor tissues may have detrimental effect as HO-1 accelerates the formation of tumor neovasculature and provides the selective advantage for tumor cells to overcome the increased oxidative stress during tumorigenesis and during treatment. The inhibition of HO-1 has been proposed as an anti-cancer therapy, however, because of non-specific effects of known HO-1 inhibitors, the discovery of ideal drug lowering HO-1 expression/activity is still an open question. Importantly, in several types of cancer HO-1/CO system exerts opposite activities, making the possible treatment more complicated. All together indicates the complex role for HO-1/CO in various in vitro and in vivo conditions.

    2012-01-01

    I started in 2002 as Editor-in-Chief of a well established journal—MST (Measurement Science and Technology). It was a time when modern means of communication offered new opportunities for the scientific community—for all scientists and engineers whether at universities, in industry or at other institutions—to access better quality information in a shorter time. This development helped us to be more efficient in our daily scientific work and to anticipate new trends faster than before. A flood of information was created by different search engines. A few online journals or journals published in emerging countries with a similar profile to MST appeared on the market. MST had to provide new answers in response to these developments. In 2002 I postulated two requirements to the journal. Firstly, the publisher has to be up to date. My impression over the years has been that IOPP is excellently organized. That has made it easier for the board members and all our reviewers to concentrate on the scientific aspects of our input to the journal. During all my visits to Bristol or my contacts with the IOPP staff I always met very professional and enthusiastic staff members. They have not only supported and encouraged the ideas and initiatives of the Editorial Board members, but they have also worked hard on establishing one of the most effective journal operations in the field of measurement science and technology. Many authors are well aware of this. Thus I am able to declare that the first requirement for a successful journal has been met. Secondly, the scientific level has to be high and the journal should attract readers from all over the world. This task was the responsibility of the Editorial Board members and of myself. Our strategy was on the one hand to ensure continuity in MST but on the other hand to be open to new trends and developments. Examples of these new aspects of the journal are fields like micro- and nanometrology, measurement techniques for

    The local organizers of the 4th BIFD (Bifurcations and Instabilities in Fluid Dynamics) Symposium held in Barcelona on 18-21 July 2011 would like to thank the editors of Fluid Dynamics Research for offering us the opportunity of publishing a peer-reviewed special issue of the journal with a selection of the contributions presented at this conference. We thank both the authors and the referees for working with us on the rather tight schedule necessary to release the issue within one year of the date of the conference. We also thank the invited speakers, B Eckhardt, L Tuckerman, and J M Vega, for contributing keynote papers to this special issue. The series of BIFD symposia started as a small workshop in Madeira, Portugal, in 2004 with no more than 20 participants. This number increased rapidly during the second and third symposia held in 2006 (Denmark) and 2009 (United Kingdom), with 40 and 110 participants, respectively. The 4th BIFD symposium has consolidated this event as one of the leading conferences in hydrodynamic stability, with nearly 200 participants from around the world. The main goal of this conference is to bring together scientists and engineers from different disciplines directly or indirectly related to fluid dynamics, bifurcation theory and hydrodynamic stability theory. The conference covered many research areas within the aforementioned fields, ranging from thermal, shear and centrifugal flows to biofluids, films, drops, viscoelastic flows and magnetohydrodynamics. The structure of the conference, with invited plenary talks and focused sessions, helped the participants find their home in the conference and share state-of-the-art knowledge within the field of hydrodynamic instabilities. The financial support from MICINN (Spanish Ministry of Science and Innovation, Grant no FIS2009-08065-E) and UPC (Universitat Politècnica de Catalunya) is greatly appreciated.

    We present a passively mode-locked, tunable soliton Ho:fiber ring oscillator, optimized for seeding of holmium-doped yttrium lithium flouride (Ho:YLF) amplifiers. The oscillator is independently tunable in central wavelength and spectral width from 2040 to 2070 nm and from 5 to 10 nm, respectively. At all settings the pulse energy within the soliton is around 800 pJ. The soliton oscillator was optimized to fully meet the spectral requirements for seeding Ho:YLF amplifiers. Its Kelly sidebands are located outside the amplifier gain spectrum, resulting in a train of about 1 ps long pedestal-free pulses with relative intensity noise of only 0.13% RMS when integrated from 1 Hz to Nyquist frequency.

    The most commonly used crystal architecture to produce 2 micrometer laser is co-doping Ho and Tm into a single host crystal. In this method, the stored energy transfer from the Tm (3)F4 to the Ho (5)I7 manifold is not fast enough to warrant high efficiency for short pulse applications. By separating the Ho and the Tm ions and doping the Tm in YALO3 and the Ho in YLF, we were able to directly pump the Ho (5)I7 manifold with 1.94 micrometers. The Ho:YLF laser has produced 33 mJ at 2.062 micrometers with a quantum efficiency of 0.88. The performance of each laser will be presented.

    The hydroxide anion plays an essential role in many chemical and biochemical reactions. But a molecular-scale description of its hydration state, and hence also its transport, in water is currently controversial. The statistical mechanical quasichemical theory of solutions suggests that \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}{\\mathrm{HO}}{\\cdot}[{\\mathrm{H}}_{2}{\\mathrm{O}}]_{3}^{-}\\end{equation*}\\end{document} is the predominant species in the aqueous phase under standard conditions. This result agrees with recent spectroscopic studies on hydroxide water clusters and with the available thermodynamic hydration free energies. In contrast, a recent ab initio molecular dynamics simulation has suggested that \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}{\\mathrm{HO}}{\\cdot}[{\\mathrm{H}}_{2}{\\mathrm{O}}]_{4}^{-}\\end{equation*}\\end{document} is the only dominant aqueous solution species. We apply adiabatic ab initio molecular dynamics simulations and find good agreement with both the quasichemical theoretical predictions and experimental results. The present results suggest a picture that is simpler, more traditional, but with additional subtlety. These coordination structures are labile but the tricoordinate species is the prominent case. This conclusion is unaltered with changes in the electronic density functional. No evidence is found for rate-determining activated interconversion of a \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength

    Ho:Tm:LuAG has been grown, examined spectroscopically, and lased at 2.1 microns. Ho:Tm:LuAG was selected for this experimental investigation when quantum-mechanical modeling predicted that it would be a good laser material for Ho laser operation on one of the 5I7 to 5I8 transitions. Lasing was achieved at 2.100 microns, one of the three wavelengths predicted to be most probable for laser action.

    This article is part of an occasional series profiling editors of the American Journal of Clinical Hypnosis (AJCH). William E. Edmonston was the second editor, succeeding Milton H. Erickson. His research focused on the use of conditioning paradigms and psychophysiological measures to explore a wide variety of hypnotic phenomena, leading to a "neo-Pavlovian" theory of neutral hypnosis as physiological relaxation (anesis). A longtime professor of psychology at Colgate University, he created an interdisciplinary undergraduate major in neuroscience, and was named New York State College Professor of the Year in 1988. He gave the Journal a new look, and a greater balance of clinical and experimental papers. The article also provides background on George Barton Cutten, George H. Estabrooks, and Frank A. Pattie, pioneers of hypnosis who were linked to Edmonston.

    Of the six or seven phases of the software engineering life cycle, requirements analysis tends to be the least understood and the least formalized. Correspondingly, a scarcity of useful software tools exist which aid in the development of user and system requirements. It is proposed that requirements analysis should culminate in a set of documents similar to those that usually accompany a delivered Software product.

    The digitization and related developments in journal editing and publishing necessitate increasing the awareness of all stakeholders of science communication in the emerging global problems and possible solutions. Journal editors and publishers are frequently encountered with the fast-growing problems of authorship, conflicts of interest, peer review, research misconduct, unethical citations, and inappropriate journal impact metrics. While the number of erroneous and unethical research papers and wasteful, or 'predatory', journals is increasing exponentially, responsible editors are urged to 'clean' the literature by correcting or retracting related articles. Indexers are advised to implement measures for accepting truly influential and ethical journals and delisting sources with predatory publishing practices. Updating knowledge and skills of authors, editors and publishers, developing and endorsing recommendations of global editorial associations, and (re)drafting journal instructions can be viewed as potential tools for improving ethics of academic journals. The aim of this Statement is to increase awareness of all stakeholders of science communication of the emerging ethical issues in journal editing and publishing and initiate a campaign of upgrading and enforcing related journal instructions.

  1. Authors, editors, and the signs, symptoms and causes of plagiarism

    PubMed Central

    Shashok, Karen

    2011-01-01

    Plagiarism and inadequate citing appear to have reached epidemic proportions in research publication. This article discusses how plagiarism is defined and suggests some possible causes for the increase in the plagiarism disease. Most editors do not have much tolerance for text re-use with inadequate citation regardless of reasons why words are copied from other sources without correct attribution. However, there is now some awareness that re-use of words in research articles to improve the writing or “the English” (which has become a common practice) should be distinguished from intentional deceit for the purpose of stealing other authors’ ideas (which appears to remain a very rare practice). Although it has become almost as easy for editors to detect duplicate text as it is for authors to re-use text from other sources, editors often fail to consider the reasons why researchers resort to this strategy, and tend to consider any text duplication as a symptom of serious misconduct. As a result, some authors may be stigmatized unfairly by being labeled as plagiarists. The article concludes with practical advice for researchers on how to improve their writing and citing skills and thus avoid accusations of plagiarism. PMID:21957412

  2. A perspective on computer documentation: System developer vs. technical editor

    1995-12-31

    Between the computer-knowledgeable {open_quotes}techie{close_quotes} and the technical writer is a chasm created by differences in knowledge bases and skills. Although this gap is widened by misunderstandings and misconceptions of system development roles, it is bridged by mutual need and dual appreciation. Often the editor/writer is {open_quotes}behind{close_quotes} from beginning to end. The writer normally joins the team after the programmers are well into system development and do not want to {open_quotes}waste time{close_quotes} discussing fundamentals. The writer is usually excluded from technical discussions because it is assumed that he/she would not understand anyway. Later in the system development cycle, the writer has no time to polish the documentation before a new version of the software is issued which implies that the documentation must be revised. Nevertheless, the editor/writer`s product is critical for the end-user`s appreciation of the software, a fact which promotes unity to complete the comprehensive package of software and documentation. This paper explores the planks in the bridge that spans the chasm between developers and their fundamental PR agents, the technical editors/writers. This paper defines approaches (e.g., The Circling Theory) and techniques (Bold Thrust!) employed for effective communication -- between software developer and technical writer as well as between the software and the end-user.

    2011-12-01

    We present the user interface and the software architecture of the Configuration Editor for the CMS experiment. The analysis workflow is organized in a modular way integrated within the CMS framework that organizes in a flexible way user analysis code. The Python scripting language is adopted to define the job configuration that drives the analysis workflow. It could be a challenging task for users, especially for newcomers, to develop analysis jobs managing the configuration of many required modules. For this reason a graphical tool has been conceived in order to edit and inspect configuration files. A set of common analysis tools defined in the CMS Physics Analysis Toolkit (PAT) can be steered and configured using the Config Editor. A user-defined analysis workflow can be produced starting from a standard configuration file, applying and configuring PAT tools according to the specific user requirements. CMS users can adopt this tool, the Config Editor, to create their analysis visualizing in real time which are the effects of their actions. They can visualize the structure of their configuration, look at the modules included in the workflow, inspect the dependences existing among the modules and check the data flow. They can visualize at which values parameters are set and change them according to what is required by their analysis task. The integration of common tools in the GUI needed to adopt an object-oriented structure in the Python definition of the PAT tools and the definition of a layer of abstraction from which all PAT tools inherit.

  5. An editor's considerations in publishing industry-sponsored studies.

    PubMed

    Droller, Michael J

    2015-03-01

    The fundamental responsibility of a journal editor is to assure that studies accepted for publication provide rigorous original scientific information and reviews that are considered important to the readership. The fundamental requirements of such reports from an editor's perspective include objectivity and transparency in each of the study design, implementation of investigation methods, acquisition of data, inclusive analysis and interpretation of results, appropriate application of statistical methods, presentation of outcomes in the context of a balanced and comprehensive review of relevant literature, and meaningful conclusions. In proceeding on these presumptions, editors then have the responsibility of obtaining rigorous, objective, and constructive reviews of these reports so that they can make an unbiased decision regarding their disposition. The fundamental objective in this is to enhance the ultimate scientific validity and value of the work if and when it is accepted for publication. Guidelines have been advanced by several organizations to identify how such editorial responsibilities can be fulfilled. These guidelines also pertain to investigators, authors, and sponsors of the studies, which the various reports and reviews describe. The present article reviews these guidelines as they relate to both industry-sponsored and investigator-initiated investigations and as relevant to the variety of reports that a scientific/medical journal such as Urologic Oncology: Seminars and Original Investigations receives for publication.

    2009-04-01

    The Protein Data Bank file format is the format most widely used by protein crystallographers and biologists to disseminate and manipulate protein structures. Despite this, there are few user-friendly software packages available to efficiently edit and extract raw information from PDB files. This limitation often leads to many protein crystallographers wasting significant time manually editing PDB files. PDB Editor, written in Java Swing GUI, allows the user to selectively search, select, extract and edit information in parallel. Furthermore, the program is a stand-alone application written in Java which frees users from the hassles associated with platform/operating system-dependent installation and usage. PDB Editor can be downloaded from http://sourceforge.net/projects/pdbeditorjl/.

    Following the FAIR data principles, research data should be Findable, Accessible, Interoperable and Reuseable. Publishing data under these principles requires to assign persistent identifiers to the data and to generate rich machine-actionable metadata. To increase the interoperability, metadata should include shared vocabularies and crosslink the newly published (meta)data and related material. However, structured metadata formats tend to be complex and are not intended to be generated by individual scientists. Software solutions are needed that support scientists in providing metadata describing their data. To facilitate data publication activities of 'GFZ Data Services', we programmed an XML metadata editor that assists scientists to create metadata in different schemata popular in the earth sciences (ISO19115, DIF, DataCite), while being at the same time usable by and understandable for scientists. Emphasis is placed on removing barriers, in particular the editor is publicly available on the internet without registration [1] and the scientists are not requested to provide information that may be generated automatically (e.g. the URL of a specific licence or the contact information of the metadata distributor). Metadata are stored in browser cookies and a copy can be saved to the local hard disk. To improve usability, form fields are translated into the scientific language, e.g. 'creators' of the DataCite schema are called 'authors'. To assist filling in the form, we make use of drop down menus for small vocabulary lists and offer a search facility for large thesauri. Explanations to form fields and definitions of vocabulary terms are provided in pop-up windows and a full documentation is available for download via the help menu. In addition, multiple geospatial references can be entered via an interactive mapping tool, which helps to minimize problems with different conventions to provide latitudes and longitudes. Currently, we are extending the metadata editor

    The kinetics of the gas phase recombination reaction HO + HO2 + He → HOOOH + He has been studied between 200 and 600 K by using the SACM/CT model and the unimolecular rate theory. The molecular properties of HOOOH were derived at the CCSD(T)/aug-cc-pVTZ ab initio level of theory, while relevant potential energy features of the reaction were calculated at the CCSD(T)/aug-cc-pVTZ//CCSD(T)/aug-cc-pVDZ level. The resulting high and low pressure limit rate coefficients are k∞ = 3.55 × 10(-12) (T/300)(0.20) cm(3) molecule(-1) s(-1) and k0 = [He] 1.55 × 10(-31) (T/300)(-3.2) cm(3) molecule(-1) s(-1). The rate coefficients calculated over the 6 × 10(-4) - 400 bar range are smaller at least in a factor of about 60 than the consensus value determined for the main reaction channel HO + HO2 → H2O + O2, indicating that the recombination pathway is irrelevant.

    I am very pleased to join the outstanding leadership team for the journal Nuclear Fusion as Scientific Editor. The journal's high position in the field of fusion energy research derives in no small measure from the efforts of the IAEA team in Vienna, the production and marketing of IOP Publishing, the Board of Editors led by its chairman Mitsuru Kikuchi, the Associate Editor for Inertial Confinement Max Tabak and the outgoing Scientific Editor, Paul Thomas. During Paul's five year tenure submissions have grown by over 40%. The usage of the electronic journal has grown year by year with about 300 000 full text downloads of Nuclear Fusion articles in 2011, an impressive figure due in part to the launch of the full 50 year archive. High quality has been maintained while times for peer review and publishing have been reduced and the journal achieved some of the highest impact factors ever (as high as 4.27). The journal has contributed greatly to building the international scientific basis for fusion. I was privileged to serve from 2003 to 2010 as chairman of the Coordinating Committee for the International Tokamak Physics Activity (ITPA) which published in Nuclear Fusion the first ITER Physics Basis (1999) and its later update (2007). The scientific basis that has been developed to date for fusion has led to the construction of major facilities to demonstrate the production of power-plant relevant levels of fusion reactions. We look forward to the journal continuing to play a key role in the international effort toward fusion energy as these exciting major facilities and the various approaches to fusion continue to be developed. It is clear that Nuclear Fusion maintains its position in the field because of the perceived high quality of the submissions, the refereeing and the editorial processes, and the availability and utility of the online journal.

    As an anti-oxidant molecule, heme oxygenase-1 (HO-1) has been implicated in the protection of lung injury by cigarette smoke (CS). The mechanisms regulating its expression have not been defined. In this report, the role of early growth response 1 (EGR-1) in the regulation of Ho-1 expression was investigated. In C57BL/6 mice with CS exposure, HO-1 was greatly increased in bronchial epithelial cells and alveolar inflammatory cells. In primary cultured mouse lung fibroblasts and RAW264.7 cells exposed to cigarette smoke water extract (CSE), an increase in HO-1 protein level was detected. In addition, CSE induced HO-1 expression was decreased in Egr-1 deficient mouse embryo fibroblasts (Egr-1{sup -/-} MEFs). Nuclear localization of EGR-1 was examined in mouse lung fibroblasts after exposure to CSE. Luciferase reporter activity assays showed that the enhancer region of the Ho-1 gene containing a proposed EGR-1 binding site was responsible for the induction of HO-1. A higher increase of alveolar mean linear intercept (Lm) was observed in lung tissues, and a larger increase in the number of total cells and monocytes/macrophages from bronchial alveolar lavage fluid was found in CS-exposed mice by loss of function of EGR-1 treatment. In summary, the present data demonstrate that EGR-1 plays a critical role in HO-1 production induced by CS.

  12. Monitoring DNA recombination initiated by HO endonuclease.

    PubMed

    Sugawara, Neal; Haber, James E

    2012-01-01

    DNA double-strand breaks (DSBs) have proven to be very potent initiators of recombination in yeast and other organisms. A single, site-specific DSB initiates homologous DNA repair events such as gene conversion, break-induced replication, and single-strand annealing, as well as nonhomologous end joining, microhomology-mediated end joining, and new telomere addition. When repair is either delayed or prevented, a single DSB can trigger checkpoint-mediated cell cycle arrest. In budding yeast, expressing the HO endonuclease under the control of a galactose-inducible promoter has been instrumental in the study of these processes by providing us a way to synchronously induce a DSB at a unique site in vivo. We describe how the HO endonuclease has been used to study the recombination events in mating-type (MAT) switching. Southern blots provide an overview of the process by allowing one to examine the formation of the DSB, DNA degradation at the break, and formation of the product. Denaturing gels and slot blots as well as PCR have provided important tools to follow the progression of resection in wild-type and mutant cells. PCR has also been important in allowing us to follow the kinetics of certain recombination intermediates such as the initiation of repair DNA synthesis or the removal of nonhomologous Y sequences during MAT switching. Finally chromatin immunoprecipitation has been used to follow the recruitment of key proteins to the DSB and in subsequent steps in DSB repair.

    On 1 January, 2004, I assumed the position of Editor-in-Chief of Journal of Physics D: Applied Physics. I will start by saying that I will do my best to justify the confidence of the journal management and publishing staff in my abilities. I was fortunate to have been able to work, as an Editorial Board member, with my predecessor, the previous Editor-in-Chief, Professor Allister Ferguson. Allister has provided a high degree of intellectual stewardship for the journal in the last five years. He has made the job appear a worthy challenge for me. I therefore take this opportunity to thank Allister on behalf of the Editorial Board and publishing staff of the journal. Several other factors contributed to my decision to accept this position. The first is the group of people who actually go about the business of publishing. The Senior Publisher, Nicola Gulley (and her predecessor Sophy Le Masurier); the Managing Editor, Jill Membrey; the Publishing Administrators, Nina Blakesley and Sarah Towell; the Production Editor, Katie Gerrard and their office staff form an amazing group and have managed to make the operation of the journal incredibly efficient. An index of this is the speed with which incoming manuscripts are processed. The average time between the receipt of a manuscript and its web publication, if accepted, is 130 days. This is three to five times shorter than for most other journals. A factor that contributes to this success is a responsive pool of referees that the publishing staff have as a valuable resource. Ultimately, the standard bearers of any journal are the referees. Therefore, a grateful `thank you' is due from all of us at J. Phys. D to all our referees, who diligently perform this honourable task. The Associate Editors of the journal, Professors Lawler, Margaritondo and O'Grady, also provide immense scientific leadership. They help in defining new directions for the journal and in the publishing process. Last, but not least, a remarkable asset of

    Forty-six medical and dental journals are published from Pakistan of which only 29 are currently recognized by the Pakistan Medical and Dental Council. Only a few are peer reviewed. Six are indexed in Medline while EMBASE Excerpta Medica and World Health Organization Index Medicus for Eastern Mediterranean Region cover others. Editors of the peer reviewed medical journals are faced with numerous problems, which relate to the authors. Some of these are: shortage of quality of manuscripts, poor quality of reviewers, problems with indexation in international indexing services particularly Medline, duplicate submission and authorship and lastly, financial problems. Patronage from the Pharma industry is the major source of revenue which itself has serious implications. Editing a medical journal is a very stressful job and the editors have to work under too many pressures. A lot of useful data is presented at medical conferences, but a vast majority of it remains unpublished for various reasons, which adversely affects the citation rate from scientists from the developing third world countries in the world of medical literature. A few lectures on medical writing and research methodology to final year medical students will expose them to the art of medical writing. Specialty organizations can be persuaded to have a session on medical writing at their conferences, which will be extremely helpful not only to the potential new authors but also others, thereby improving the quality of their manuscripts. In addition to regular seminars, workshops for authors, reviewers and training courses for editors, subscribing to local medical journals by healthcare professionals and libraries are some of the measures that will help improve the situation to a great extent.

    The Met Office's numerical weather prediction and climate model code, the Unified Model (UM), is almost 25 years old. Up to the present day the UM has been able to be run efficiently on many of the worlds most powerful computers, helping to keep the Met Office at the forefront of climate prediction and weather forecasting. However, with performance increases from each new generation of computers now being primarily provided by an increase in the amount of parallelism rather than an increase in the clock-speed of the processors themselves, running higher resolutions of the UM now faces the double challenge of code scalability and numerical accuracy. The UM's atmospheric dynamical core makes use of a finite-difference scheme on a regular latitude-longitude grid. The regular latitude-longitude mesh results in an increasingly disparate grid resolution as the mesh resolution increases due to lines of longitude converging at the poles. For example, a 10km resolution at mid-latitudes would result in a 12m resolution at the poles. The difference in resolution leads to increased communication at the poles and load balance issues which are known to impair scalability; it also leads to issues with numerical accuracy and smaller time-steps due to the difference in scale. To address this problem the Met Office, NERC and STFC initiated the GungHo project. The primary aim of this project is to deliver a scalable, numerically accurate dynamical core. This dynamical core is scheduled to become operational around the year 2022. The project is currently investigating the use of quasi-uniform meshes, such as triangular, icosahedral and cubed-sphere meshes, using finite element methods. The associated GungHo software infrastructure is being developed to support multiple meshes and element types thus allowing for future model development. GungHo is also proposing a novel separation of concerns for the software implementation of the dynamical core. This approach distinguishes between

  16. Heterogeneous Reaction of HO2 Radical with Dicarboxylic Acid Particles

    HOx(OH+ HO2) radical plays a central role in the tropospheric chemistry. Recently, the heterogeneous loss of HO2 by aerosol particles is a potentially important HOx sink in the troposphere suggested from observation study. However, there have been few studies for loss of HO2 by aerosols. In this study, we measured the HO2 uptake coefficients for four dicarboxylic acids (succinic acid, glutaric acid, adipic acid, and pimelic acid) aerosol particles under ambient conditions (760Torr and 296K) using an aerosol flow tube(AFT) coupled with a chemical conversion /laser-induced fluorescence(CC/LIF) technique. The CC/LIF technique enabled experiments to be performed at almost the same HO2 radical concentration as that in the atmosphere(-10^8 molecules/cm^3). In this system, the effect of the self-reaction of HO2 in the gas phase can be neglected. HO2 radicals were injected into the AFT through a vertically movable Pyrex tube. Injector position dependent profiles of LIF intensity were measured as a function of aerosol concentration at 30% and 70% of relative humilities (RH). Determined HO2 uptake coefficients by succinic acid, glutaric acid, adipic acid, and pimelic acid aerosol particles at 30% RH were 0.05 +/- 0.02, 0.07 +/- 0.03, 0.02 +/- 0.01, and 0.06 +/- 0.03, respectively, while the uptake coefficients by those particles at 70% RH were 0.13 +/- 0.05, 0.13 +/- 0.03, 0.06 +/- 0.01, and 0.11 +/- 0.03, respectively. These results suggest that compositions and relative humidity are significant to the HO2 uptake. We will discuss the potential HO2 loss processes.

    I am Professor Ephrahim Garcia, an Associate Professor at Sibley School of Mechanical and Aerospace Engineering at Cornell University in Ithaca, New York. I have been at Cornell University since 2002, spent four years as a Program Manager at the Defense Advanced Research Project Agency from 1998-2002, and before that seven years at the Department of Mechanical Engineering at Vanderbilt University in Nashville, Tennessee. I have served on the Editorial Advisory Board of Smart Materials and Structures (SMS) for the last six years. It is a humbling thing to be asked to take up the post of Editor-in-Chief in a field with so many talented researchers. I would like to say a heartfelt thanks to the members of the Editorial Board and IOP Publishing for their confidence in me. Most importantly, I would like to thank Professor Vijay Varadan of the University of Arkansas and Professor Richard Claus of Virginia Polytechnic Institute and State University for their efforts in launching the journal 16 years ago. They have been stewards, promoters and, especially Vijay, key to the operation and function of SMS for all these years, and our research community is indebted to them. Professors Varadan and Claus have dedicated their careers to the area of smart materials and structures and we are very grateful for their leadership, mentoring and contribution. SMS is a thriving journal offering papers on all technical areas concerned with smart materials, systems and structures from the micro- and nanoscale to the macroscale. The journal is undergoing some major changes, including the recent transferal of papers to IOP Publishing's peer-review management system. With this new system authors can expect fast publication times of around 4 or 5 months from submission, and excellent author service.

    The hydroxyl (OH) and hydroperoxyl (HO2) radicals, together known as HOx, play a vital role in atmospheric chemistry by controlling the oxidative capacity of the troposphere. The atmospheric lifetime and concentrations of many trace reactive species, such as volatile organic compounds (VOCs), are determined by HOx radical levels. Therefore, the ability to accurately predict atmospheric HOx concentrations from a detailed knowledge of their sources and sinks is a very useful diagnostic tool to assess our current understanding of atmospheric chemistry. Several recent field studies have observed significantly lower concentrations of HO2 radicals than predicted using box models, where HO2 loss onto aerosols was suggested as a possible missing sink [1, 2]. However, the mechanism on HO2 uptake onto aerosols and its impact on ambient HOx levels are currently not well understood. To improve our understanding of this process, we have conducted laboratory experiments to measure HO2 uptake coefficients onto submicron aerosol particles. The FAGE (Fluorescence Assay by Gas Expansion) technique, a highly sensitive laser induced fluorescence based detection method, was used to monitor HO2 uptake kinetics onto aerosol particles in an aerosol flow tube. The application of the FAGE technique allowed for kinetic experiments to be performed under low HO2 concentrations, i.e. [HO2] < 109 molecules cm-3. HO2 radicals were produced by the photolysis of water vapour in the presence of O2 and aerosol particles were produced either by atomizing dilute salt solutions or by homogeneous nucleation. HO2 uptake coefficients (γ) have been measured for single-component solid and aqueous inorganic salt and organic aerosol particles with a wide range of hygroscopicities. HO2 uptake coefficients on solid particles were below the detection limit (γ < 0.001), whereas on aqueous aerosols uptake coefficients were somewhat larger (γ = 0.001 - 0.008). HO2 uptake coefficients were highest on aerosols

  4. Editorial independence at medical journals owned by professional associations: a survey of editors.

    Davis, Ronald M; Müllner, Marcus

    2002-10-01

    The purpose of this study was to assess the degree of editorial independence at a sample of medical journals and the relationship between the journals and their owners. We surveyed the editors of 33 medical journals owned by not-for-profit organizations ("associations"), including 10 journals represented on the International Committee of Medical Journal Editors (nine of which are general medical journals) and a random sample of 23 specialist journals with high impact factors that are indexed by the Institute for Scientific Information. The main outcome measures were the authority to hire, fire, and oversee the work of the editor; the editor's tenure and financial compensation; control of the journal's budget; publication of material about the association; and the editor's perceptions about editorial independence and pressure over editorial content. Of the 33 editors, 23 (70%) reported having complete editorial freedom, and the remainder reported a high level of freedom (a score of > or = 8, where 10 equals complete editorial freedom and 1 equals no editorial freedom). Nevertheless, a substantial minority of editors reported having received at least some pressure in recent years over editorial content from the association's leadership (42%), senior staff (30%), or rank-and-file members (39%). The association's board of directors has the authority to hire (48%) or fire (55%) the editor for about half of the journals, and the editor reports to the board for 10 journals (30%). Twenty-three editors (70%) are appointed for a specific term (median term = 5 years). Three-fifths of the journals have no control over their profit, and the majority of journals use the association's legal counsel and/or media relations staff. Stronger safeguards are needed to give editors protection against pressure over editorial content, including written guarantees of editorial freedom and governance structures that support those guarantees. Strong safeguards are also needed because editors

  10. Gene targeting, genome editing: from Dolly to editors.

    One of the most powerful strategies to investigate biology we have as scientists, is the ability to transfer genetic material in a controlled and deliberate manner between organisms. When applied to livestock, applications worthy of commercial venture can be devised. Although initial methods used to generate transgenic livestock resulted in random transgene insertion, the development of SCNT technology enabled homologous recombination gene targeting strategies to be used in livestock. Much has been accomplished using this approach. However, now we have the ability to change a specific base in the genome without leaving any other DNA mark, with no need for a transgene. With the advent of the genome editors this is now possible and like other significant technological leaps, the result is an even greater diversity of possible applications. Indeed, in merely 5 years, these 'molecular scissors' have enabled the production of more than 300 differently edited pigs, cattle, sheep and goats. The advent of genome editors has brought genetic engineering of livestock to a position where industry, the public and politicians are all eager to see real use of genetically engineered livestock to address societal needs. Since the first transgenic livestock reported just over three decades ago the field of livestock biotechnology has come a long way-but the most exciting period is just starting.

  12. Making a height field editor for WireMan

    SciTech Connect

    Cano, J.

    1994-04-01

    The focus of this project is to modify and write new code for a program named WireMan. WireMan draws in 3-D using items from a menu (cones, spheres, etc.). One of the items which can be selected is called the height field. The height field, as it currently appears in WireMan, is a 3-D graph of a set equation. Originally, the height field was supposed to be able to display any curve the user may need. However, because of lack of time and programmers, the height field was never completed and has remained at this constant curve since its creation. To change it a user needs to modify progra mcode, thus, a height field editor is necessary. Through the editor, the user will be able to modify the height field by either equation of matrix. The latter will allow the user to determine a curve for the height field according to matrix or grid entries (of the form n x n, where up to 10 x 10 entries can be made). The grid will then be stretched and evaluated over the height field plane (which consists of 512-512 generated entries) and the curve will then be generated. The difficulties and the results of the project are outlined according to their occurrences throughout the paper.

  14. A Generic Metadata Editor Supporting System Using Drupal CMS

    Pan, J.; Banks, N. G.; Leggott, M.

    2011-12-01

    Metadata handling is a key factor in preserving and reusing scientific data. In recent years, standardized structural metadata has become widely used in Geoscience communities. However, there exist many different standards in Geosciences, such as the current version of the Federal Geographic Data Committee's Content Standard for Digital Geospatial Metadata (FGDC CSDGM), the Ecological Markup Language (EML), the Geography Markup Language (GML), and the emerging ISO 19115 and related standards. In addition, there are many different subsets within the Geoscience subdomain such as the Biological Profile of the FGDC (CSDGM), or for geopolitical regions, such as the European Profile or the North American Profile in the ISO standards. It is therefore desirable to have a software foundation to support metadata creation and editing for multiple standards and profiles, without re-inventing the wheels. We have developed a software module as a generic, flexible software system to do just that: to facilitate the support for multiple metadata standards and profiles. The software consists of a set of modules for the Drupal Content Management System (CMS), with minimal inter-dependencies to other Drupal modules. There are two steps in using the system's metadata functions. First, an administrator can use the system to design a user form, based on an XML schema and its instances. The form definition is named and stored in the Drupal database as a XML blob content. Second, users in an editor role can then use the persisted XML definition to render an actual metadata entry form, for creating or editing a metadata record. Behind the scenes, the form definition XML is transformed into a PHP array, which is then rendered via Drupal Form API. When the form is submitted the posted values are used to modify a metadata record. Drupal hooks can be used to perform custom processing on metadata record before and after submission. It is trivial to store the metadata record as an actual XML file

    2009-06-01

    Breaches of publication ethics such as plagiarism, data fabrication and redundant publication are recognised as forms of research misconduct that can undermine the scientific literature. We surveyed journal editors to determine their views about a range of publication ethics issues. Questionnaire sent to 524 editors-in-chief of Wiley-Blackwell science journals asking about the severity and frequency of 16 ethical issues at their journals, their confidence in handling such issues, and their awareness and use of guidelines. Responses were obtained from 231 editors (44%), of whom 48% edited healthcare journals. The general level of concern about the 16 issues was low, with mean severity scores of <1 (on a scale of 0-3) for all but one. The issue of greatest concern (mean score 1.19) was redundant publication. Most editors felt confident in handling the issues, with <15% feeling "not at all confident" for all but one of the issues (gift authorship, 22% not confident). Most editors believed such problems occurred less than once a year and >20% of the editors stated that 12 of the 16 items never occurred at their journal. However, 13%-47% did not know the frequency of the problems. Awareness and use of guidelines was generally low. Most editors were unaware of all except other journals' instructions. Most editors of science journals seem not very concerned about publication ethics and believe that misconduct occurs only rarely in their journals. Many editors are unfamiliar with available guidelines but would welcome more guidance or training.

  16. HoBi-like viruses: an emerging group of pestiviruses.

    PubMed

    Bauermann, Fernando V; Ridpath, Julia F; Weiblen, Rudi; Flores, Eduardo F

    2013-01-01

    The genus Pestivirus is composed of 4 important pathogens of livestock: Bovine viral diarrhea virus 1 and 2 (BVDV-1 and BVDV-2), Classical swine fever virus (CSFV), and Border disease virus of sheep (BDV). BVDV are major pathogens of cattle, and infection results in significant economic loss worldwide. A new putative pestivirus species, tentatively called "HoBi-like," "BVDV-3," or "atypical pestiviruses," was first identified in Europe in fetal bovine serum (FBS) imported from Brazil. HoBi-like viruses are related to BVDV at the genetic and antigenic levels. Further, the disease caused by these new viruses resembles clinical presentations historically associated with BVDV infection, including growth retardation, reduced milk production, respiratory disease, reduced reproductive performance, and increased mortality among young stock. Current BVDV diagnostic tests may fail to detect HoBi-like viruses or to differentiate between BVDV and HoBi-like viruses. Further, commercial tests for BVDV exposure, based on serological response, do not reliably detect HoBi-like virus exposure, and cross protection against HoBi-like viruses conferred by current BVDV vaccines is likely limited. As many HoBi-like viruses, characterized to date, were isolated from FBS originating from Brazil, it is assumed that the agent is probably widespread in Brazilian herds. Nevertheless, reports of natural infection in Southeast Asia and Europe demonstrate that these viruses are not restricted to South America. Increased demand for FBS has led to widespread distribution of FBS originating in HoBi-like virus endemic regions. The contamination of such FBS with HoBi-like viruses may lead to spread of this virus to other regions.

    We reported 25 cases of cerebellopontine angle (CPA) tumor operation with Ho:YAG laser assistance during the operative procedure. We analysed the surgical effects of Ho:YAG laser, compare it with CO2 Nd:YAG argon laser, and illustrated its features and parameters. We think that Ho:YAG laser can be used to ablate and vaporize the tumor efficiently in the operation of the CPA tumors whose vascular supply is abundant and the texture is very tough. It can be used to reduce the bleeding and cooperate to incise tumor in the operation and improve the curable effect of the surgery.

    We report fabrication and operation of multi-watt level waveguide lasers utilizing holmium-doped yttrium aluminum garnet (Ho:YAG). The waveguides were fabricated using ultrafast laser inscription, which relies on a chirped pulse ytterbium fiber laser to create depressed cladding structures inside the material. A variety of waveguides were created inside the Ho:YAG samples. We demonstrate output powers of ∼2  W from both a single-mode 50 μm waveguide laser and a multimode 80 μm waveguide laser. In addition, laser action from a co-doped Yb:Ho:YAG sample under in-band pumping conditions was demonstrated.

In this article the author outlines his experiences using the system, noting both the advantages to explore and pitfalls to avoid in using this tool. Writers Workbench is especially useful for improving a writer's basic skills - punctuation, spelling, and grammar. When used effectively, Writers Workbench can cut down on wordiness and improve the consistency of a manual. It can help in the creation of a table of contents, index, glossary, and bibliography and in checking readability. Furthermore, by creating user-defined dictionaries, authors or editors can customize the tool to fit their purposes and styles. However, Writers Workbench is not good at catching problems relating to organization, focus, and clarity.

  1. Highlighting impact: Do editors' selections identify influential papers?

    NASA Astrophysics Data System (ADS)

    Antonoyiannakis, Manolis

    A recent trend in scientific publishing is that journal editors highlight each week a select set among the papers published (usually) in their respective journals. The highlighted papers are deemed of higher quality, importance, or interest than the 'average' paper and feature prominently in the publishers' websites. We perform a citation analysis of the highlighted papers for a number of journals from various publishers in physics. By comparing the performance of highlighted papers relative to (a) typical papers and (b) highly cited papers in their source journals and in other journals in the field, we explore whether, and to what extent, the selection process at the time of publication identifies papers that will turn out to be influential. We discuss the broader implications for research assessment.

    Understanding the molecular mechanisms underlying complex disorders requires the integration of data and knowledge from different sources including free text literature and various biomedical databases. To facilitate this process, we created the Biomedical Concept Diagram Editor (BCDE) to help researchers distill knowledge from data and literature and aid the process of hypothesis development. A key feature of BCDE is the ability to capture information with a simple drag-and-drop. This is a vast improvement over manual methods of knowledge and data recording and greatly increases the efficiency of the biomedical researcher. BCDE also provides a unique concept matching function to enforce consistent terminology, which enables conceptual relationships deposited by different researchers in the BCDE database to be mined and integrated for intelligible and useful results. We hope BCDE will promote the sharing and integration of knowledge from different researchers for effective hypothesis development.

    It is an honor and a privilege to be appointed the Interim Executive Editor for the IJTMB; I am lucky to have some initiatives that were already in development by the previous editorial team that I hope to bring to fruition over the next few months. First, I hope to increase the Journal’s Internet presence through social media to expand readership and encourage new submitters. The second initiative is a mentoring program to assist writers with their submissions to the Journal. Finally, I, and the rest of the editorial staff, will continue to evaluate the process, procedures, and forms used in peer review. I hope to move these initiatives forward and by doing so, bring in new readers, submitters, and reviewers to the Journal. PMID:27974945

  4. Educating science editors: is there a comprehensive strategy?

    The article considers available options to educate science editors in the fast-transforming digital environment. There is no single course or resource that can cover their constantly changing and diversifying educational needs. The involvement in research, writing, and reviewing is important for gaining editing skills, but that is not all. Membership in editorial associations and access to updated scholarly information in the field are mandatory for maintaining editorial credentials. Learned associations offer access to a few widely-recognized periodicals. There are also formal training courses covering issues in science writing and ethical editing, but no high-level evidence data exist to promote any of these. Networking with like-minded specialists within the global and regional editorial associations seems a useful strategy to upgrade editorial skills and resolve problems with the quality control and digitization of scholarly periodicals.

    1992-01-01

    A new computer program called the X-Windows Interactive Data Editor (XIDE) was developed and demonstrated as a prototype application for editing radio metric data in the orbit-determination process. The program runs on a variety of workstations and employs pull-down menus and graphical displays, which allow users to easily inspect and edit radio metric data in the orbit data files received from the Deep Space Network (DSN). The XIDE program is based on the Open Software Foundation OSF/Motif Graphical User Interface (GUI) and has proven to be an efficient tool for editing radio metric data in the navigation operations environment. It was adopted by the Magellan Navigation Team as their primary data-editing tool. Because the software was designed from the beginning to be portable, the prototype was successfully moved to new workstation environments. It was also itegrated into the design of the next-generation software tool for DSN multimission navigation interactive launch support.

  6. An Internet-based ontology editor for medical appropriateness criteria.

    Kahn, C E

    1998-04-01

    Appropriateness criteria and practice guidelines seek to promote the cost-effectiveness use of medical interventions, and can be most useful when integrated with computer-based patient records and order-entry systems. Building an abstract model (ontology) of appropriateness criteria can require considerable effort among investigators at geographically dispersed institutions. To facilitate the construction and maintenance of ontologies for clinical appropriateness criteria, the author developed an Internet-based system for viewing and editing the knowledge model. The system, called NEON (Network-based Editor for ONtologies), uses the World Wide Web as a platform-independent user interface. NEON allows users to edit the indexing terms and the semantic network that form the ontology for a set of appropriateness criteria. Ontologies built using the system can be imported and exported using an open, internationally standardized format based on the Standard Generalized Markup Language (SGML).

    2004-10-01

    As the incoming editor of Global Biogeochemical Cycles, I would like to introduce myself and my ideas for the journal to Eos readers and to current and potential GBC authors. I've had a somewhat ``roaming'' scientific evolution, coming from ``straight'' chemistry through hard-rock geochemistry to chemical oceanography, the field in which I did my Ph.D. I taught marine chemistry at Florida State University for a number of years, and developed an interest in ocean/atmosphere interactions and atmospheric chemistry. In 1987 I took on my present job at the Max Planck Institute for Chemistry, in Mainz, Germany, and, after leaving the seacoast, my interests shifted to interactions between the terrestrial biosphere and atmosphere, including the role of vegetation fires. My present focus is on the role of biogenic aerosols and biomass smoke in regulating cloud properties and influencing climate.

    NASA Technical Reports Server (NTRS)

    1992-01-01

    Software development is widely considered to be a bottleneck in the development of complex systems, both in terms of development and in terms of maintenance of deployed systems. Cost of software development and maintenance can also be very high. One approach to reducing costs and relieving this bottleneck is increasing the reuse of software designs and software components. A method for achieving such reuse is a software parts composition system. Such a system consists of a language for modeling software parts and their interfaces, a catalog of existing parts, an editor for combining parts, and a code generator that takes a specification and generates code for that application in the target language. The Advanced Software Development Workstation is intended to be an expert system shell designed to provide the capabilities of a software part composition system.

  9. Kinetics and mechanism of HO2 and DO2 disproportionations

    Kircher, C. C.; Sander, S. P.

    1984-01-01

    A flash photolysis/UV abosrption technique was used to study the HO2 + HO2 and DO2 + DO2 reactions in the gas phase. Rate constants were measured at pressures between 100 and 700 torr of Ar and N2, and at temperatures between 230 and 420 K with up to 10 torr of added water vapor. The overall disproportionation rate constants for the reaction is given as the sum of pressure-independent and pressure-dependent terms. A kinetic analysis shows that both reactions have a zero-pressure bimolecular component and a termolecular component which is linearly dependent on pressure up to 700 torr. A priori estimates of the vibrational frequencies of the product of the HO2 + HO2 reaction suggest binding energies of 12-20 kcal per mol (for the initial association).

    An investigation of the yrast structure of the odd-Z {sup 159}Ho nucleus to high spin has been performed. The {sup 159}Ho nucleus was populated by the reaction {sup 116}Cd({sup 48}Ca,p4n{gamma}) at a beam energy of 215 MeV, and resulting {gamma} decays were detected by the Gammasphere spectrometer. The h{sub 11/2} yrast band has been significantly extended up to I{sup {pi}=}75/2{sup -} (tentatively 79/2{sup -}). A lower frequency limit for the second (h{sub 11/2}){sup 2} proton alignment was extracted consistent with the systematics of this alignment frequency, indicating an increased deformation with neutron number in the Ho isotopes. The energy-level splitting between the signature partners in the h{sub 11/2} structures of the Ho isotopes and the neighboring N=92 isotones is discussed.

    Home Care is one of the main objectives of Ambient Intelligence. Nowadays, the disabled and elderly population, which represents a significant part of our society, requires novel solutions for providing home care in an effective way. In this chapter, we present HoCaMA, a hybrid multiagent architecture that facilitates remote monitoring and care services for disabled patients at their homes. HoCaMA combines multiagent systems and Web services to facilitate the communication and integration with multiple health care systems. In addition, HoCaMA focuses on the design of reactive agents capable of interacting with different sensors present in the environment, and incorporates a system of alerts through SMS and MMS mobile technologies. Finally, it uses Radio Frequency IDentification and JavaCard technologies to provide advanced location and identification systems, as well as automatic access control facilities. HoCaMA has been implemented in a real environment and the results obtained are presented within this chapter.

    Fourier Transform spectra of holmium (Ho) in the UV spectral range from 31,530 to 25,000 cm‑1 (317 to 400 nm) have been investigated, particularly focusing on the ionic lines. The distinction between the different degrees of ionization (I, II, and III) is based on differences in signal-to-noise ratios from two Ho spectra, which have been measured with different buffer gases, i.e., neon and argon. Based on 106 known Ho ii and 126 known Ho iii energy levels, 97 lines could be classified as transitions of singly ionized Ho and 9 lines could be classified as transitions of doubly ionized Ho. Of the 97 Ho ii lines, 6 have not been listed in the extant literature. Another 215 lines have been assigned to Ho ii, though they could not be classified on the basis of the known energy levels.

  14. Uptake of HO2 Radicals Onto Dust Aerosols

    OH and HO2 radicals play an important role in the troposphere by controlling its oxidative capacity and therefore the concentration of many trace species. Several field studies have observed significantly lower concentrations of HO2 radicals than predicted using box models (1,2). HO2 loss onto aerosols has been suggested as a possible sink. Mineral dust has an estimated annual flux of 2000 Tg year-1 (3). However, there has only been one study of HO2 uptake onto Arizona Test Dust (ATD) surfaces (4) and there are currently no published studies for dust aerosols. Therefore, the aim of this study was to measure the HO2 uptake coefficient onto ATD aerosols over a range of humidities and for different HO2 concentrations, as well as investigating the uptake as a function of the exposure time to the aerosol, for which a dependence had been observed for aqueous salt aerosols (5). Uptake coefficients were measured for ATD aerosols at atmospheric pressure and at 291 K using a Fluorescence Assay by Gas Expansion (FAGE) detector combined with a flow tube. HO2 was formed from the photolysis of water vapour and was injected into the flow tube using a moveable injector, which was placed in six different positions along the flow tube. The non stable aerosol output was produced by stirring ATD in a bottle producing a dust cloud which was entrained into a flow. The aerosol number concentration was measured using a Condensation Particle Counter (CPC) and was converted into a surface area using the average radius of one aerosol. The uptake coefficient was then able to be calculated by assuming first order kinetics. The HO2 uptake coefficient was measured at a relative humidity of between 6 and 75% and at initial HO2 concentrations of ~ 0.3 - 1 × 10^9 molecule cm-3. Average uptake coefficients of 0.018 × 0.006 and 0.031 × 0.008 were measured for the higher and lower HO2 concentrations respectively, and the impact investigated using a constrained box model. A time dependence was also

    2011-01-01

    TIn the autumn of 2010 I became the Editor-in Chief of European Journal of Physics (EJP). EJP is a place for teachers, instructors and professors to exchange their views on teaching physics at university level and share their experience. It is general opinion that no good research is possible without connection with good, high-quality teaching, at the university level in particular. Therefore excellence in physics teaching is important to the physics community. European Journal of Physics is proud of its contribution to achieving this goal. As Editor-in-Chief, I will continue to work to this general objective of the journal. We will publish articles on specific topics in physics, stressing originality of presentation and suitability for use in students'laboratories, lectures and physics teaching in general. We will also publish more pedagogical papers presenting the achievements of particular teaching methods. In addition, we will continue to publish special sections on particular areas of physics, as well as the annual special section on physics competitions. European Journal of Physics is in good shape. Due to the work of the previous editors and the publisher, the readership is high and growing steadily, and many excellent papers are being submitted and published. I hope that this positive trend for the journal will continue, and I will do my best to keep to this high standard. A few words about myself. I work in the Institute of Physics in Warsaw, Poland. My main research interests are in theoretical quantum optics and I have published about 80 research papers on this topic. For many years I was involved in teaching physics at university and in high school. I am a co-author of a textbook on physics for high-school students and of a problem book in quantum mechanics. For the last ten years, I have been involved in the International Physics Olympiad and over the last few years I have been a member of the Editorial Board of European Journal of Physics.

  8. A survey of orthopaedic journal editors determining the criteria of manuscript selection for publication

    PubMed Central

    2011-01-01

    Background To investigate the characteristics of editors and criteria used by orthopaedic journal editors in assessing submitted manuscripts. Methods Between 2008 to 2009 all 70 editors of Medline listed orthopaedic journals were approached prospectively with a questionnaire to determine the criteria used in assessing manuscripts for publication. Results There was a 42% response rate. There was 1 female editor and the rest were male with 57% greater than 60 years of age. 67% of the editors worked in university teaching hospitals and 90% of publications were in English. The review process differed between journals with 59% using a review proforma, 52% reviewing an anonymised manuscript, 76% using a routine statistical review and 59% of journals used 2 reviewers routinely. In 89% of the editors surveyed, the editor was able to overrule the final decision of the reviewers. Important design factors considered for manuscript acceptance were that the study conclusions were justified (80%), that the statistical analysis was appropriate (76%), that the findings could change practice (72%). The level of evidence (70%) and type of study (62%) were deemed less important. When asked what factors were important in the manuscript influencing acceptance, 73% cited an understandable manuscript, 53% cited a well written manuscript and 50% a thorough literature review as very important factors. Conclusions The editorial and review process in orthopaedic journals uses different approaches. There may be a risk of language bias among editors of orthopaedic journals with under-representation of non-English publications in the orthopaedic literature. PMID:21527007

  1. Reaction of HO2 with O3 and the effect of water vapor on HO2 kinetics

    NASA Technical Reports Server (NTRS)

    Demore, W. B.

    1979-01-01

    The effects of temperature and water vapor concentration on the ratio of the rate constant of the reaction HO2 + O3 yields OH + 2(O2) to the square root of the rate constant for the reaction HO2 + HO2 yields H2O2 + O2 are determined. Photolysis of H2-O2-O3 mixtures at 253.7 nm was carried out with H2O pressures in the range 0 to 15 torr at a temperature range of -42.5 to 61 C along with 184.9 nm photolysis of H2O-O2-O3 mixtures. It is shown that the rate of O3 photolysis is suppressed by the addition of water vapor and it is suggested that this effect is realized in the HO2 + HO2 yields H2O2 + O2 reaction. The calculated expression for the temperature dependence of the rate constant ratio is found to be in good agreement with that calculated from separate rate constants. Rate constants determined for the reaction OH + HO2 yields H2O + O2 are found to be higher than those previously determined, presumably due to increased pressure, indicating that atmospheric models should take into account the possible pressure dependences of the reactions considered.

    Nobody is better suited to describe data than the scientist who created it. This description about a data is called Metadata. In general terms, Metadata represents the who, what, when, where, why and how of the dataset [1]. eXtensible Markup Language (XML) is the preferred output format for metadata, as it makes it portable and, more importantly, suitable for system discoverability. The newly developed ORNL Metadata Editor (OME) is a Web-based tool that allows users to create and maintain XML files containing key information, or metadata, about the research. Metadata include information about the specific projects, parameters, time periods, and locations associated with the data. Such information helps put the research findings in context. In addition, the metadata produced using OME will allow other researchers to find these data via Metadata clearinghouses like Mercury [2][4]. OME is part of ORNL s Mercury software fleet [2][3]. It was jointly developed to support projects funded by the United States Geological Survey (USGS), U.S. Department of Energy (DOE), National Aeronautics and Space Administration (NASA) and National Oceanic and Atmospheric Administration (NOAA). OME s architecture provides a customizable interface to support project-specific requirements. Using this new architecture, the ORNL team developed OME instances for USGS s Core Science Analytics, Synthesis, and Libraries (CSAS&L), DOE s Next Generation Ecosystem Experiments (NGEE) and Atmospheric Radiation Measurement (ARM) Program, and the international Surface Ocean Carbon Dioxide ATlas (SOCAT). Researchers simply use the ORNL Metadata Editor to enter relevant metadata into a Web-based form. From the information on the form, the Metadata Editor can create an XML file on the server that the editor is installed or to the user s personal computer. Researchers can also use the ORNL Metadata Editor to modify existing XML metadata files. As an example, an NGEE Arctic scientist use OME to register

    Neutrinos, and in particular their tiny but non-vanishing masses, can be considered one of the doors towards physics beyond the Standard Model. Precision measurements of the kinematics of weak interactions, in particular of the 3H β-decay and the 163Ho electron capture (EC), represent the only model independent approach to determine the absolute scale of neutrino masses. The electron capture in 163Ho experiment, ECHo, is designed to reach sub-eV sensitivity on the electron neutrino mass by means of the analysis of the calorimetrically measured electron capture spectrum of the nuclide 163Ho. The maximum energy available for this decay, about 2.8 keV, constrains the type of detectors that can be used. Arrays of low temperature metallic magnetic calorimeters (MMCs) are being developed to measure the 163Ho EC spectrum with energy resolution below 3 eV FWHM and with a time resolution below 1 μs. To achieve the sub-eV sensitivity on the electron neutrino mass, together with the detector optimization, the availability of large ultra-pure 163Ho samples, the identification and suppression of background sources as well as the precise parametrization of the 163Ho EC spectrum are of utmost importance. The high-energy resolution 163Ho spectra measured with the first MMC prototypes with ion-implanted 163Ho set the basis for the ECHo experiment. We describe the conceptual design of ECHo and motivate the strategies we have adopted to carry on the present medium scale experiment, ECHo-1K. In this experiment, the use of 1 kBq 163Ho will allow to reach a neutrino mass sensitivity below 10 eV/ c 2. We then discuss how the results being achieved in ECHo-1k will guide the design of the next stage of the ECHo experiment, ECHo-1M, where a source of the order of 1 MBq 163Ho embedded in large MMCs arrays will allow to reach sub-eV sensitivity on the electron neutrino mass.

    OH and HO2 (HOx) radicals are closely coupled and OH is responsible for the majority of the oxidation in the troposphere and controls the concentrations of many trace species. Therefore, it is important to be able to accurately predict HOx concentrations. However, some field measurement studies have reported significantly lower HO2 radical concentrations than calculated by constrained box models using detailed chemical mechanisms. Although the inclusion of halogen chemistry into the mechanisms can explain much of the differences in the marine boundary layer (MBL) (1,2), HO2 uptake by aerosols has been suggested as a possible sink in the MBL (2), the Arctic troposphere (3) and the upper troposphere (4). There have been very few laboratory studies (5,6) on HO2 uptake by aerosols and the rates and mechanism is still uncertain. The HO2 uptake coefficients were measured for a variety of atmospherically relevant inorganic and organic aerosols. The measurements were performed using an aerosol flow tube combined with a Fluorescence Assay by Gas Expansion (FAGE) detector. The sensitive FAGE cell allowed low HO2 concentrations (108-109 molecule cm-3) to be injected into the flow tube using a moveable injector. By moving the injector along the flow tube, position dependent HO2 decays were able to be recorded which when plotted against the total aerosol surface area allowed an uptake coefficient to be obtained. The aerosols were generated using an atomiser or by homogeneous nucleation and the total aerosol surface area was measured using a Scanning Mobility Particle Sizer. The HO2 uptake coefficient (γ) was measured at room temperature for dry inorganic salts and dry organics (γ< 0.004), wet inorganic salts and wet organics (γ= 0.002-0.005), wet copper doped ammonium sulfate aerosols (γ= 0.28± 0.05) and ammonium sulfate aerosols doped with different molar amounts of iron (γ= 0.003-0.06). The pH dependence of the HO2 uptake coefficient was investigated, however no

    Nobody is better suited to "describe" data than the scientist who created it. This "description" about a data is called Metadata. In general terms, Metadata represents the who, what, when, where, why and how of the dataset. eXtensible Markup Language (XML) is the preferred output format for metadata, as it makes it portable and, more importantly, suitable for system discoverability. The newly developed ORNL Metadata Editor (OME) is a Web-based tool that allows users to create and maintain XML files containing key information, or metadata, about the research. Metadata include information about the specific projects, parameters, time periods, and locations associated with the data. Such information helps put the research findings in context. In addition, the metadata produced using OME will allow other researchers to find these data via Metadata clearinghouses like Mercury [1] [2]. Researchers simply use the ORNL Metadata Editor to enter relevant metadata into a Web-based form. How is OME helping Big Data Centers like ORNL DAAC? The ORNL DAAC is one of NASA's Earth Observing System Data and Information System (EOSDIS) data centers managed by the ESDIS Project. The ORNL DAAC archives data produced by NASA's Terrestrial Ecology Program. The DAAC provides data and information relevant to biogeochemical dynamics, ecological data, and environmental processes, critical for understanding the dynamics relating to the biological components of the Earth's environment. Typically data produced, archived and analyzed is at a scale of multiple petabytes, which makes the discoverability of the data very challenging. Without proper metadata associated with the data, it is difficult to find the data you are looking for and equally difficult to use and understand the data. OME will allow data centers like the ORNL DAAC to produce meaningful, high quality, standards-based, descriptive information about their data products in-turn helping with the data discoverability and

    To characterize medical editors by determining their demographics, training, potential sources of conflict of interest (COI), and familiarity with ethical standards. We selected editors of clinical medical journals with the highest annual citation rates. One hundred eighty-three editors were electronically surveyed (response rate, 52%) on demographics and experiences with editorial training, publication ethics, industry, and scientific publication organizations. Editors reported formal (76%) and informal (89%) training in medical editing topics. Most editors saw publication ethics issues (e.g., authorship, COIs) at least once a year. When presented with four questions about editorial issues discussed in commonly cited authoritative policy sources, performance was poor on topics of authorship (30% answered correctly), COI (15%), peer review (16%), and plagiarism (17%). Despite this, confidence level in editorial skills on a Likert scale from the beginning to the end of the survey dropped only slightly from 4.2 to 3.9 (P<0.0001). Our study presents a current look at editors of major clinical medical journals. Most editors reported training in medical editing topics, saw ethical issues regularly, and were aware of scientific publication organizations, but their knowledge of four common and well-disseminated publication ethics topics appears poor.

The saddle point for H atom exchange is about 13 kcal/mol below the energy of H + O2; therefore, this region of the surface should be accessible during H + O2 recombination and methathesis reactions.

    When a Ne/O2 mixture is codeposited at 4.3 K with a Ne/H2 mixture that has been passed through a microwave discharge, the infrared spectrum of the resulting deposit includes prominent absorptions of the three vibrational fundamentals of HO2 and seven relatively weak absorptions in the infrared and near-infrared, only one of them previously reported, that can be assigned to overtones and combination bands of that product. Similar assignments are made for DO2. A new, broad absorption at 702.9 cm(-1) appears close to the gas-phase absorption of HOHOH(-) at 697 cm(-1). Isotopic substitution experiments support that assignment. Evidence is also presented for the stabilization of HOHO(-). Absorptions near the vibrational fundamentals of H2O and an absorption at 3472.4 cm(-1) grow on exposure of the deposit to radiation of wavelength shorter than 345 nm. These absorptions are assigned to the H2O(HO) complex, in agreement with the results of an earlier argon-matrix study. In both studies, photodestruction of HO2 molecules that have H2O trapped in a nearby site results in formation of the complex. Because the discharge through Ne/H2 supports ion production, photodetachment of the resulting HOHOH(-) is an additional source of the complex. Other absorptions may be contributed by the bending fundamental of HO2(+) and by a cation complex with H2.

    The rapid growth of DNA sequencing throughput in recent years implies that graphical interfaces for viewing and correcting errors must now handle large numbers of reads, efficiently pinpoint regions of interest and automate as many tasks as possible. We have adapted consed to reflect this. To allow full-feature editing of large datasets while keeping memory requirements low, we developed a viewer, bamScape, that reads billion-read BAM files, identifies and displays problem areas for user review and launches the consed graphical editor on user-selected regions, allowing, in addition to longstanding consed capabilities such as assembly editing, a variety of new features including direct editing of the reference sequence, variant and error detection, display of annotation tracks and the ability to simultaneously process a group of reads. Many batch processing capabilities have been added. The consed package is free to academic, government and non-profit users, and licensed to others for a fee by the University of Washington. The current version (26.0) is available for linux, macosx and solaris systems or as C++ source code. It includes a user's manual (with exercises) and example datasets. http://www.phrap.org/consed/consed.html dgordon@uw.edu .

  14. Misunderstanding publication bias: editors are not blameless after all.

    PubMed

    Senn, Stephen

    2012-01-01

    In analysing whether there is an editorial bias in favour of positive studies, researchers have made implicit assumptions that are implausible. In particular, to justify the conclusion that there is no bias because observed editorial acceptance rates do not favour positive studies, the assumption that the decision to submit an article is based solely on quality would be required. If, on the other hand, submission were based on perceived probability of acceptance, negative and positive studies would not differ in terms of acceptance rates, but in terms of quality. It is shown, using a simple graphical model, how similar underlying situations as regards the relationship between quality and probability of acceptance on the one hand and study outcome (positive or negative) and probability of acceptance on the other could produce dramatically different results depending on the behaviour of authors. Furthermore, there is, in fact, some evidence that submitted negative studies are, on average, of higher quality than positive ones. This calls into question the standard interpretation of the studies examining editorial bias. It would appear that despite similar probabilities of acceptance for negative and positive studies, editors could be discriminating against negative studies.

    The Netherlands' Cadastre, Land Registry and Mapping Agency - in short Kadaster - collects and registers administrative and spatial data on property and the rights involved. This includes for ships, aircraft and telecommunications networks. Doing so, Kadaster protects legal certainty. The Kadaster publishes many large authoritative datasets including several key registers of the Dutch Government (Topography, Addresses and Buildings). Furthermore Kadaster is also developing and maintaining the PDOK shared service, in which about 100 spatial datasets are being published in several formats, including an incredible amount of detailed geospatial objects. Geospatial objects include all plots of land, all buildings, all roads and all lampposts. These objects are spatially and/or conceptually related, but are maintained by different data curators. As a result these datasets are syntactically and architecturally disjoint, and using them together currently requires non-trivial human labor. In response to this, Kadaster is currently publishing its geo-spatial data assets as Linked Open Data. The standardized query language for Linked Open Geodata is GeoSPARQL. Unfortunately, current tooling does not support writing and evaluating GeoSPARQL queries. This paper presents GeoYASGUI, a GeoSPARQL editor and result-set viewer with IDE capabilities. GeoYASGUI is not a new software product, but an integration of and a collection of updates to existing Open Source libraries. With GeoYASGUI it becomes possible to query the rich Open Data assets of the Kadaster.

    The hydroxyl (OH) and hydroperoxyl (HO2) radicals, known collectively as HOx radicals, are the key reactants that control the oxidative capacity of the troposphere and the atmospheric lifetimes and concentrations of most trace reactive species, i.e. NOx, O3 and volatile organic compounds. Therefore, in order to gain an overall understanding of atmospheric chemistry and to predict the fate of atmospheric pollutants, a detailed knowledge of the sources and sinks of HOx species and their steady-state atmospheric concentrations is crucial. To this end, field measurements of atmospheric HOx concentrations have been recently compared to model predictions to gauge our level of understanding of atmospheric chemistry of trace reactive species. Box models incorporating known gas-phase chemistry have significantly overpredicted steady-state HO2 levels in comparison to field observations, suggesting heterogeneous uptake onto aerosols as a possible missing atmospheric sink for HO2 radicals [1-2]. However, relatively few laboratory studies have been performed to determine the kinetic parameters for HO2 loss onto aerosols, and thus the ability to assess the impact of this mechanism on HOx levels is limited. The goal of this laboratory study is to improve our understanding of the tropospheric HOx budget by measuring HO2 uptake kinetics onto aerosol particles. In this work, HO2 radicals were produced by the photolysis of water vapour and the FAGE (Fluorescence Assay by Gas Expansion) technique was used to monitor HO2 loss kinetics onto aerosol particles in an aerosol flow tube setup. FAGE is a highly sensitive laser-induced fluorescence based detection method for HOx radicals that has allowed for kinetic measurements to be performed under low HO2 concentrations minimizing gas-phase HO2 self reaction, i.e. for [HO2] < 109 molecules cm-3. The mass accommodation coefficient was determined by measuring HO2 uptake onto Cu(II)-doped ammonium sulfate aerosols. Reactive uptake coefficients

    Quantum yields, phi, of OH and HO2 in the ultraviolet photolysis of HO2NO2 (peroxynitric acid, PNA) at 193 and 248 nm and that of NO3 at 193, 248 and 308 nm are reported. Quantum yields were measured using pulsed excimer laser photolysis combined with pulsed laser induced fluorescence (PLIF) detection of OH radicals and cavity ring-down (CRD) detection of NO3 radicals. HO2 radicals were quantified by converting them to OH via the HO2 + NO --> OH + NO2 reaction and detecting OH. The quantum yields obtained at 296 K are: phi193 nm(OH) = 0.21 +/- 0.12, phi248 nm(OH) = 0.085 +/- 0.08, phi193 nm(HO2) = 0.56 +/- 0.09, phi248 nm(HO2) = 0.89 +/- 0.26, phi193 nm(NO3) = 0.35 +/- 0.09, phi248 nm(NO3) = 0.08 +/- 0.04 and phi308 nm(NO3) = 0.05 +/- 0.02. The quoted uncertainties are 2sigma (95% confidence level) and include estimated systematic errors. Our results are compared with the previous quantum yield measurements of OH (MacLeod et al., J. Geophys. Res., 1988, 93, 3813) and NO2 (Roehl et al., 2001, J. Phys. Chem., 105, 1592) at 248 nm and the discrepancies are discussed. The rate coefficients at 298 K for reactions of OH with HO2NO2, H2O2, HNO3 and NO are also reported.

    At the end of 2011 I will retire as Editor-in-Chief of Semiconductor Science and Technology, and I am very pleased to announce that the job will be taken over by Professor Kornelius Nielsch. In the ten years I have held this position, I have seen many new topics entering the journal: spintronics, organic semiconductors, and Dirac fermion physics, to name just a few. The journal has also witnessed a strong internationalization of the authorship, with an especially strong increase in contributions from the Far East—a growth that is likely to continue in the coming years. I am certain that Kornelius will do an excellent job in guiding the journal through the developments of the coming decade. I would like to thank the publishing team of SST, or rather the three consecutive teams I witnessed during my tenure at the journal, for the help and support they have given me. The people at IOP Publishing are doing a great job in running the journal, and have made it possible to considerably reduce the time to publication for our submissions. I much enjoyed the collaboration with the other members of the Editorial Board; our annual meetings have always been a source of inspiration. Last, but certainly not least, I would like to thank you, the scientific community, authors, referees and readers, for your continuing support of the journal.

  2. Kinetics and mechanism of the glyoxal + HO2 reaction: conversion of HO2 to OH by carbonyls.

    PubMed

    da Silva, Gabriel

    2011-01-27

    The kinetics of the glyoxal + HO(2) reaction have been investigated using computational chemistry and statistical reaction rate theory techniques, with consideration of a novel pathway that results in the conversion of HO(2) to OH. Glyoxal is shown to react with HO(2) to form an α-hydroxyperoxy radical with additional α-carbonyl functionality. Intramolecular H atom abstraction from the carbonyl moiety proceeds with a relatively low barrier, facilitating decomposition to OH + CO + HC(O)OH (formic acid). Time-dependent master equation simulations demonstrate that direct reaction to form OH is relatively slow at ambient temperature. The major reaction product is predicted to be collisionally deactivated HC(OH)(OO)CHO, which predominantly dissociates to reform the reactants under low-NO(x) conditions. The mechanism described here for the conversion of OH to HO(2) is available to a diverse range of carbonyls, including methylglyoxal, glycolaldehyde, hydroxyacetone, and glyoxylic acid, and energy surfaces are reported for the reaction of these species with HO(2).

    The Avogadro project has developed an advanced molecule editor and visualizer designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related areas. It offers flexible, high quality rendering, and a powerful plugin architecture. Typical uses include building molecular structures, formatting input files, and analyzing output of a wide variety of computational chemistry packages. By using the CML file format as its native document type, Avogadro seeks to enhance the semantic accessibility of chemical data types. The work presented here details the Avogadro library, which is a framework providing a code library and application programming interface (API) with three-dimensional visualization capabilities; and has direct applications to research and education in the fields of chemistry, physics, materials science, and biology. The Avogadro application provides a rich graphical interface using dynamically loaded plugins through the library itself. The application and library can each be extended by implementing a plugin module in C++ or Python to explore different visualization techniques, build/manipulate molecular structures, and interact with other programs. We describe some example extensions, one which uses a genetic algorithm to find stable crystal structures, and one which interfaces with the PackMol program to create packed, solvated structures for molecular dynamics simulations. The 1.0 release series of Avogadro is the main focus of the results discussed here. Avogadro offers a semantic chemical builder and platform for visualization and analysis. For users, it offers an easy-to-use builder, integrated support for downloading from common databases such as PubChem and the Protein Data Bank, extracting chemical data from a wide variety of formats, including computational chemistry output, and native, semantic support for the CML file format. For developers, it can be easily extended via a powerful

  7. Polymeric lithography editor: Editing lithographic errors with nanoporous polymeric probes.

    A new lithographic editing system with an ability to erase and rectify errors in microscale with real-time optical feedback is demonstrated. The erasing probe is a conically shaped hydrogel (tip size, ca. 500 nm) template-synthesized from track-etched conical glass wafers. The "nanosponge" hydrogel probe "erases" patterns by hydrating and absorbing molecules into a porous hydrogel matrix via diffusion analogous to a wet sponge. The presence of an interfacial liquid water layer between the hydrogel tip and the substrate during erasing enables frictionless, uninterrupted translation of the eraser on the substrate. The erasing capacity of the hydrogel is extremely high because of the large free volume of the hydrogel matrix. The fast frictionless translocation and interfacial hydration resulted in an extremely high erasing rate (~785 μm(2)/s), which is two to three orders of magnitude higher in comparison with the atomic force microscopy-based erasing (~0.1 μm(2)/s) experiments. The high precision and accuracy of the polymeric lithography editor (PLE) system stemmed from coupling piezoelectric actuators to an inverted optical microscope. Subsequently after erasing the patterns using agarose erasers, a polydimethylsiloxane probe fabricated from the same conical track-etched template was used to precisely redeposit molecules of interest at the erased spots. PLE also provides a continuous optical feedback throughout the entire molecular editing process-writing, erasing, and rewriting. To demonstrate its potential in device fabrication, we used PLE to electrochemically erase metallic copper thin film, forming an interdigitated array of microelectrodes for the fabrication of a functional microphotodetector device. High-throughput dot and line erasing, writing with the conical "wet nanosponge," and continuous optical feedback make PLE complementary to the existing catalog of nanolithographic/microlithographic and three-dimensional printing techniques.

    Hydroxyl (OH) and hydroperxy (HO 2) radicals, collectively known as HO x, were measured during an intensive field study in January and February 2004 in New York City. Much less OH and HO 2 levels were observed than in the summer of 2001 at the same site. On average, the maximum daytime mixing ratios were 0.05 pptv (1.4×10 6 cm -3) for OH and 0.7 pptv for HO 2, which were about one fifth of the levels in the summer of 2001. A zero-dimensional chemical model, based on the regional atmospheric chemical mechanism (RACM) and constrained by the measured concentrations of O 3, NO, NO 2, CO, SO 2, speciated volatile organic compounds (VOCs) and meteorological parameters, was used to study the HO x chemistry in this environment. The model generally reproduced the daytime OH well, with a median measured-to-model ratio of 0.98. However, HO 2 was significantly under-predicted both at day and at night, with a median measured-to-model ratio of 6.0 during daytime. The discrepancy is pronounced when NO concentrations were high, a result that is consistent with some previous studies in urban environments. Photolysis of HONO was the dominant calculated HO x source during daytime; O 3 reactions with alkenes became the main calculated HO x source at night. The main calculated HO x sink was the OH reaction with NO 2. The discrepancy between measured and modeled HO 2 may be caused by significant HO x production that is missing in the model. An additional HO 2 production of up to 3×10 7 cm -3 s -1 (1.1 pptv s -1), which is three times the calculated HO x production, is needed. This HO 2 production can come either from unknown new HO x production or from unknown HO 2 recycling that does not go through OH.

    We use the Wetterich equation for foliated spacetimes to study the renormalization group flow of projectable Hořava-Lifshitz gravity coupled to n Lifshitz scalars. Using novel results for anisotropic heat kernels, the matter-induced beta functions for the gravitational couplings are computed explicitly. The renormalization group flow exhibits an UV attractive anisotropic Gaussian fixed point where Newton's constant vanishes and the extra scalar mode decouples. This fixed point ensures that the theory is asymptotically free in the large-n expansion, indicating that projectable Hořava-Lifshitz gravity is perturbatively renormalizable. Notably, the fundamental fixed point action does not obey detailed balance.

    We have investigated the detailed field and temperature dependence of the dielectric constant, dielectric losses, electric polarization, magnetization and magnetostriction (MS) in orthorhombic HoMn2O5 single crystals. HoMn2O5 displays incommensurate antiferromagnetic ordering below 39 K, becoming commensurate on further cooling. The commensurate-incommensurate transition takes place at low temperatures. The inherent magnetic frustration in this material is lifted by a small lattice distortion, primarily involving shifts of the Mn3+ cations and giving rise to a canted antiferroelectric phase. Colossal magnetostriction (CMS) effect was observed and a novel phase transition diagram was build.

    Editors have a responsibility to retract seriously flawed articles from their journals. However, there appears to be little consistency in journals' policies or procedures for this. In a qualitative study, we therefore interviewed editors of science journals using semi-structured interviews to investigate their experience of retracting articles. We identified potential barriers to retraction, difficulties in the process and also sources of support and encouragement. Our findings have been used as the basis for guidelines developed by the Committee on Publication Ethics.

    Laboratory studies were conducted to investigate the kinetics of HO2 radical uptake onto submicron inorganic salt aerosols. HO2 reactive uptake coefficients were measured at room temperature using an aerosol flow tube and the Fluorescence Assay by Gas Expansion (FAGE) technique that allowed for measurements to be conducted under atmospherically relevant HO2 concentrations ([HO2] = 10(8) to 10(9) molecule cm(-3)). The uptake coefficient for HO2 uptake onto dry inorganic salt aerosols was consistently below the detection limit (γ(HO2) < 0.004). The mass accommodation coefficient of HO2 radicals onto Cu(II)-doped (NH4)2SO4 aerosols was measured to be α(HO2) = 0.4 ± 0.3 representing the kinetic upper limit to γ. For aqueous (NH4)2SO4, NaCl and NH4NO3 aerosols not containing traces of transition metal ions, a range of γ(HO2) = 0.003-0.02 was measured. These values were much lower than γ values previously measured on aqueous (NH4)2SO4 and NaCl aerosols and also those typically used in atmospheric models (γ(HO2) = 0.1-1.0). Evidence is presented showing that the HO2 uptake coefficients onto aqueous salt aerosol particles are dependent both on the exposure time to the aerosol and on the HO2 concentration used.

    The nuclear structure properties of the low-lying and excited states of Holmium isotopes have been studied within the framework of Projected Shell Model. The theoretical results are found to be in the reasonable agreement with the observed ones. The theoretical B (M 1) / B (E 2) estimates of 158Ho are seen to reproduce the same systematics as shown by the observed ones. However, for 159,161,163Ho, the B (E 2) transition probabilities for the ground state band have been predicted for transitions for which the experimental values are not available.

    The potential energy surface for the H + O2 to HO2(asterisk) to HO + O reaction has been investigated in the region of the minimum energy path using CASSCF/contracted CI (CCI) calculations with a large basis set. The results show no barrier for the addition of an H atom to O2, in agreement with previous studies. A crossing between the surface for electrostatic (OH dipole-O quadrupole) interaction and that for the formation of an O-O chemical bond, at r(infinity) of about 5.5 a(0), results in a small (about 0.5 kcal/mol) barrier.

    As I begin my tenure as Editor-in-Chief of Journal of Physics: Condensed Matter (JPCM), I look upon this opportunity as both an honour and a real challenge. The journal is in great shape thanks to the work of my predecessors, Marshall Stoneham and David Ferry. The journal's solid reputation is based largely on the work these gentlemen have done over the past decade. The other main reason for the success of JPCM is the amazing staff in Bristol; keep up the good work, please. When discussing the journal with scientists from all corners of the globe, one thing is always mentioned—JPCM is a very reliable journal with well-written, high-quality papers, and a fast but rigorous peer-review process that provides fair, detailed and constructive referee reports for the benefit of authors. This is due almost entirely to our great authors and referees; we rely on them every day—thank you. As the new Editor-in-Chief I hope to continue to improve still further the journal's status in condensed matter science. As mentioned above, our reputation is excellent, but the reality is that we live in a world of bibliometrics and rankings. Over the past few years JPCM has been repositioned as a journal at the forefront of condensed matter physics, and the impact of the journal should increase further as a result of continued emphasis on commissioning in cutting-edge areas identified by the Editorial Board and the journal team. In addition to regular papers, JPCM has a number of other content streams that authors and readers can benefit from. Fast track communications (FTCs) offer exceptionally fast publication for work of the highest impact and urgency. By their select nature, FTCs benefit from personal treatment by the Editorial Board and the average receipt-to-first-decision time is just 11 days (the average receipt-to-publication time is just 45 days). Topical reviews in JPCM make the journal one of the most authoritative sources of review content for condensed matter physics

    As a journal that reports advances in atomic, molecular and optical science (AMO), Journal of Physics B: Atomic, Molecular and Optical Physics (J. Phys. B) provides the AMO research community with three unique fora: topical reviews, tutorials and special issues. Developed under the leadership of editor Jan Michael Rost and his Editorial Board, these sections have cemented J. Phys. B's reputation as a major journal showcasing the AMO community's advances. For me, an AMO scientist, it is therefore a special pleasure to be entrusted with continuing the tradition of excellence established by Jan Michael and the Editorial Board. I intend to build on this foundation by ensuring that the journal makes full use of these tools. Topical reviews: a unique focus When J. Phys. B becomes the first journal you turn to for initial reviews about important emerging areas in your field, we as an Editorial Board will have succeeded. To us, a topical review is different from a traditional review—a topical review focuses on emerging sub-fields of AMO physics. Its function is to alert and educate our readers about emerging opportunities. Topical reviews can also serve a closely related function for readers: keeping us up-to-date with critical technologies that lie slightly outside our own fields, such as advances in free-electron lasers science, (which will surely affect our field). Our overall goal is to make your research more productive because of the topical reviews you read within the journal. Tutorials J. Phys. B tutorials are aimed at graduate students or researchers venturing into a new field. Just as in my own research group I encourage all graduate students to write their theses in a way that will be useful to both future graduate students and the larger community beyond my group, J. Phys. B has designed tutorials to fill this function on the journal scale. Thus, tutorial authors are able to write in greater depth than can be included in a paper in nature, science or in the

    Flash-lamp-pumped, room-temperature Ho:Tm:Cr:YAG and Ho:Tm:Er:YLF are compared for single but long pulse operation, with pulse lengths of approximately 1.0 mus. Under similar operating conditions in normal-mode operation, a slope efficiency of 0.0331 was observed for Ho:Tm:Er:YLF compared with 0.0047 for Ho:Tm:Cr:YAG. For Q-switched operation, Ho:Tm:Er:YLF yielded a slope efficiency of 0.0075. In comparison, a slope efficiency of 0.0012 was obtained for Ho:Tm:Cr:YAG. Two methods of producing long pulse lengths are compared: pulse selection of normal-mode relaxation oscillations and Q-switching in a long resonator. Theoretical models developed in a companion paper for normal-mode relaxation oscillations and Q-switching in quasi-four-level solid-state lasers are in agreement with the experimental results.

    Biomedical journals are the main route for disseminating the results of health-related research. Despite this, their editors operate largely without formal training or certification. To our knowledge, no body of literature systematically identifying core competencies for scientific editors of biomedical journals exists. Therefore, we aimed to conduct a scoping review to determine what is known on the competency requirements for scientific editors of biomedical journals. We searched the MEDLINE®, Cochrane Library, Embase®, CINAHL, PsycINFO, and ERIC databases (from inception to November 2014) and conducted a grey literature search for research and non-research articles with competency-related statements (i.e. competencies, knowledge, skills, behaviors, and tasks) pertaining to the role of scientific editors of peer-reviewed health-related journals. We also conducted an environmental scan, searched the results of a previous environmental scan, and searched the websites of existing networks, major biomedical journal publishers, and organizations that offer resources for editors. A total of 225 full-text publications were included, 25 of which were research articles. We extracted a total of 1,566 statements possibly related to core competencies for scientific editors of biomedical journals from these publications. We then collated overlapping or duplicate statements which produced a list of 203 unique statements. Finally, we grouped these statements into seven emergent themes: (1) dealing with authors, (2) dealing with peer reviewers, (3) journal publishing, (4) journal promotion, (5) editing, (6) ethics and integrity, and (7) qualities and characteristics of editors. To our knowledge, this scoping review is the first attempt to systematically identify possible competencies of editors. Limitations are that (1) we may not have captured all aspects of a biomedical editor's work in our searches, (2) removing redundant and overlapping items may have led to the

    I have been involved with Modelling and Simulation in Materials Science and Engineering (MSMSE) from the very beginning when it was merely an idea, over 14 years ago, to the current journal that is well supported by the community. During my time as Editor there have been many changes in the journal, including the introduction of electronic submissions, web-based services and free printed colour where it is essential to the article, as well as completely free colour online. The journal has seen excellent growth in the number and quality of submissions and the number of articles published continues to rise, enabling us to expand the journal to eight issues in 2005. Web accesses and downloads have greatly surpassed even my wildest dreams. In my opinion, the emergence of MSMSE as a top materials modelling journal has confirmed the vision of Institute of Physics Publishing (IOPP) and the Executive Board that this area of science and engineering was ripe for a specialized journal. I feel that, having seen the journal through the early years and watched it grow into a successful arena for multidisciplinary materials research, it is now an appropriate time for me to hand over the reins. The journal has a great foundation for future growth and development and is supported by an excellent Editorial Board, who have given me a great deal of help and advice over the years. I feel sure that they will continue to support the journal when Bill Curtin, Brown University, takes over on 1 July 2005. Bill has the diverse experience in modelling at the atomic, dislocation, and continuum levels to lead the journal to new heights. Finally I would like to thank all of the readers, authors and referees who have greatly contributed to MSMSE over the years. Thank you for your support and help, and I hope you will continue to support the journal. Last, but not least, I would like to thank the staff at IOPP. Without their expert assistance, the journal could not have been as successful as it is

We demonstrate a 2 μm room temperature Ho:LuVO4 laser, resonantly pumped by a 1.94 μm Tm:YAP laser. By use of an output coupler with T=10% transmission, the Ho:LuVO4 laser generated continuous-wave output power of 2.5 W at 2074.18 nm, with a beam quality factor of Mx2=My2=1.3, for a total incident pump power of 19.4 W. The slope efficiency with respect to the pump power was 17.6%, and the optical-to-optical efficiency was 12.9%. Moreover, we obtained a Ho:LuVO4 laser that operated at 2073.77 and 2055.27 nm, by using different output couplers with transmissions of T=15 and 30%.

    A pulsed laser photolysis technique has been employed to investigate the kinetics of the radical-radical reaction O((sup 3)P) + HO2 OH + O2 over the temperature range 266-391 K in 80 Torr of N2 diluent gas. O((sup 3)P) was produced by 248.5-nm KrF laser photolysis of O3 followed by rapid quenching of O(1D) to O((sup 3)P) while HO2 was produced by simultaneous photolysis of H2O2 to create OH radicals which, in turn, reacted with H2O2 to yield HO2. The O((sup 3)P) temporal profile was monitored by using time-resolved resonance fluorescence spectroscopy. The HO2 concentration was calculated based on experimentally measured parameters. The following Arrhenius expression describes our experimental results: k(sub 1)(T) equals (2.91 +/- 0.70) x 10(exp -11) exp[(228 +/- 75)/T] where the errors are 2 sigma and represent precision only. The absolute uncertainty in k, at any temperature within the range 266-391 K is estimated to be +/- 22 percent. Our results are in excellent agreement with a discharge flow study of the temperature dependence of k(sub 1) in 1 Torr of He diluent reported by Keyser, and significantly reduce the uncertainty in the rate of this important stratospheric reaction at subambient temperatures.

    The performance of two multiply doped Ho:YAG lasers has been characterized as a function of the laser rod temperature. From the experimental results, the dependence of the slope efficiency and threshold on temperature has been extracted. Threshold can be correlated with the occupation of the lower laser level. Implications on the optimum operating temperature are discussed.

    We consider the branch of the projectable Hořava-Lifshitz model which exhibits ghost instabilities in the low energy limit. It turns out that, due to the Lorentz violating structure of the model and to the presence of a finite strong coupling scale, the vacuum decay rate into photons is tiny in a wide range of phenomenologically acceptable parameters. The strong coupling scale, understood as a cutoff on ghosts' spatial momenta, can be raised up to Λ ˜ 10 TeV. At lower momenta, the projectable Hořava-Lifshitz gravity is equivalent to General Relativity supplemented by a fluid with a small positive sound speed squared (10-42 ≲) c s 2 ≲ 10-20, that could be a promising candidate for the Dark Matter. Despite these advantages, the unavoidable presence of the strong coupling obscures the implementation of the original Hořava's proposal on quantum gravity. Apart from the Hořava-Lifshitz model, conclusions of the present work hold also for the mimetic matter scenario, where the analogue of the projectability condition is achieved by a non-invertible conformal transformation of the metric.

    The hydroxyl (OH) and peroxy radicals, both the hydroperoxy radicals (HO2) and organic peroxy radicals (RO2) play an important role in atmospheric chemistry. In addition to controlling lifetimes of many trace gases important to issues of global climate change, reactions of these radicals can also lead to the production of ozone and secondary organic aerosols in the atmosphere. Previous measurements of these radicals in forest environments characterized by high mixing ratios of isoprene and low mixing ratios of NOx have shown serious discrepancies with modeled concentrations. These results bring into question our understanding of the atmospheric chemistry of isoprene and other biogenic VOCs under low NOxconditions. In the summer of 2016, HO2 and HO2* (S HO2 + αRO2) radicals were measured using the Laser-Induced Fluorescence Fluorescence Assay by Gas Expansion (LIF-FAGE) technique as part of the Program for Research on Oxidants: PHtochemistry, Emissions, and Transport- Atmospheric Measurements of Oxidants in Summer (PROPHET-AMOS). This campaign took place in a forested area in northern Michigan characterized by high mixing ratios of isoprene and low mixing ratios of NOx. Ambient measurements from this campaign will be compared to previous measurements at this site and to modeled predictions.

    The diffusion of OH, HO2, and O3 in He, and of OH in air, has been investigated using a coated-wall flow tube reactor coupled to a chemical ionization mass spectrometry. The diffusion coefficients were determined from measurements of the loss of the reactive species to the flow tube wall as a function of pressure. On the basis of the experimental results, D(OH-He) = 662 +/- 33 Torr cm2 s-1, D(OH-air) = 165 +/- 20 Torr cm2 s-1, D(HO2-He) = 430 +/- 30 Torr cm2 s-1, and D(O3-He) = 410 +/- 25 Torr cm2 s-1 at 296 K. We show that the measured values for OH and HO2 are in better agreement with measured values of their polar analogues (H2O and H2O2) compared with measured values of their nonpolar analogues (O and O2). The measured value for OH in air is 25% smaller than that for O (the nonpolar analogue). The difference between the measured value for HO2 and O2 (the nonpolar analogue) in air is expected to be even larger. Also we show that calculations of the diffusion coefficients based on Lennard-Jones potentials are in excellent agreement with the measurements. This gives further confidence that these calculations can be used to estimate accurate diffusion coefficients for conditions where laboratory data currently do not exist.

    A pulsed laser photolysis technique has been employed to investigate the kinetics of the radical-radical reaction O((sup 3)P) + HO2 OH + O2 over the temperature range 266-391 K in 80 Torr of N2 diluent gas. O((sup 3)P) was produced by 248.5-nm KrF laser photolysis of O3 followed by rapid quenching of O(1D) to O((sup 3)P) while HO2 was produced by simultaneous photolysis of H2O2 to create OH radicals which, in turn, reacted with H2O2 to yield HO2. The O((sup 3)P) temporal profile was monitored by using time-resolved resonance fluorescence spectroscopy. The HO2 concentration was calculated based on experimentally measured parameters. The following Arrhenius expression describes our experimental results: k(sub 1)(T) equals (2.91 +/- 0.70) x 10(exp -11) exp[(228 +/- 75)/T] where the errors are 2 sigma and represent precision only. The absolute uncertainty in k, at any temperature within the range 266-391 K is estimated to be +/- 22 percent. Our results are in excellent agreement with a discharge flow study of the temperature dependence of k(sub 1) in 1 Torr of He diluent reported by Keyser, and significantly reduce the uncertainty in the rate of this important stratospheric reaction at subambient temperatures.

    Hydroperoxyl radical (HO2) is a key species to atmospheric chemistry. At warm temperatures, the hydroperoxyl radical (HO2) and NO2 come to a rapid steady state with pernitric acid (HO2NO2). This paper presents the derivation of HO2 from observations of HO2NO2 and NO2 in metropolitan Atlanta, US in winter 2014 and summer 2015. HO2 was observed to have a diurnal cycle with morning concentrations suppressed by high NO from the traffic. At night, derived HO2 levels were nonzero and exhibited correlations with O3 and NO3, consistent with previous studies that ozonolysis and oxidation by NO3 are sources of nighttime HO2. Measured and model calculated HO2 were in reasonable agreement: Without the constraint of measured HO2NO2 , the model reproduced HO2 with a model-to-observed ratio (M/O) 1.27 (r = 0.54) for winter, 2014, and 0.70 (r = 0.80) for summer, 2015. Adding measured HO2NO2 as a constraint, the model predicted HO2 with M/O = 1.13 ((r = 0.77) for winter 2014, and 0.90 ((r = 0.97) for summer 2015. These results demonstrate the feasibility of deriving HO2 from HO2NO2 measurements in warm regions where HO2NO2 has a short lifetime.

    Vainshtein. We had hoped that the Nobel Symposium should be a signal for improved relations between East and West, but in this respect we failed. The Symposium was held in the small town of Marstrand, a summer resort on an island outside Göteborg. The idea was to have it relatively close to home and to show the participants perhaps the best part of the local nature. Another motive was to keep the participants semi-isolated to provide ample time for discussions. With the somewhat heavy programme we found that even so, the days were not long enough. This Symposium was the second Nobel Symposium on elementary particle physics. The first one, also organized by our group, was held in 1968. We hope and believe that the next one need not be awaited another 18 years! The Symposium was made possible by a generous grant from the Nobel Foundation. An additional grant from the Royal Swedish Academy of Sciences was also essential. A grant from Nordita made it possible to invite some ten Nordic observers. We also gratefully acknowledge help with the organization of the Symposium from the city of Goteborg, the city of Kungälv, Volvo, Skandinaviska Enskilda banken, Ericsson AB and IBM Sweden. We thank all the participants for all their efforts, to come to our remote part of the world, to give excellent talks, to write up their talks astonishingly quickly and to share with us so much of their knowledge and expertise. Last but not least we are indebted to the members of the organizing committee, members of the group and the secretarial staff.

    An increased expression and activity of the heme oxygenase-1 (HO-1) in the liver has been observed in models of hepatic damage. Nitric oxide (NO) seems to be involved in HO-1 regulation. The aim of this work is to assess HO-1 induction and heme oxygenase (HO) activity in rats with bile duct ligation (BDL). We have assessed the effect of chronic inhibition of the NO synthesis by N(G)-nitro-l-arginine methyl ester (l-NAME) on HO-1 induction and HO activity. In the BDL animals, compared with sham-operated ones, we found an increased plasma nitrite and bilirubin concentration, and a marked liver expression of inducible nitric oxide synthase and HO-1, assessed by both Western blot and immunohistochemistry. Chronic l-NAME treatment prevented plasma nitrite increase in animals subjected to BDL. BDL animals treated with l-NAME, compared with untreated BDL rats, showed an important decrease in HO-1 expression and in HO activity (assessed as a decreased plasma bilirubin and bilirubin excretion). In conclusion, our experiments show parallel changes in expression and activity of HO-1 and NOS2 activity in the BDL model of liver damage and suggest that increased NO production is involved in HO-1 overexpression.

  5. HO(x) Measurements in PEM Tropics B with the Airborne Tropospheric Hydrogen Oxides Sensor (ATHOS)

    2001-01-01

    The primary objective of PEM Tropics B was to study the processes responsible for the production and loss of tropospheric ozone over the tropical Pacific. This region of the globe contains very clean air as well as aged, polluted air that was advected from both the Asian and American continents. Understanding ozone requires understanding of HO(x) (HO(x) = OH + HO2) chemistry, since the reaction between H02 and NO leads to ozone production and the production of OH often requires ozone loss. In addition, OH is the atmosphere's primary oxidant. Since most atmospheric oxidation is thought to occur in the tropical lower troposphere, measurements during PEM Tropics B should provide an important test of the OH abundances and distributions. Thus, understanding and thoroughly testing HO(x) processes was an important objective of PEM Tropics B. Several issues need to be tested, One is HO, production rates and sources, since HO,, production directly affects ozone production and loss. Another is HO(x) behavior in and around clouds, since HO(x) is lost to cloud particles, but convection may bring HO(x) precursors from near the surface to the upper troposphere. A third is the rise and fall of HO(x) at sunrise and sunset, since these variations give strong indications of the important sources and sinks of HO(x). Making and interpreting high-quality OH and H02 measurements from the NASA DC-8 during PEM Tropics B is the objective of this research effort.

    Aggressive tumors induce tumor-supporting changes in the benign parts of the prostate. One factor that has increased expression outside prostate tumors is hemoxygenase-1 (HO-1). To investigate HO-1 expression in more detail, we analyzed samples of tumor tissue and peritumoral normal prostate tissue from rats carrying cancers with different metastatic capacity, and human prostate cancer tissue samples from primary tumors and bone metastases. In rat prostate tumor samples, immunohistochemistry and quantitative RT-PCR showed that the main site of HO-1 synthesis was HO-1+ macrophages that accumulated in the tumor-bearing organ, and at the tumor-invasive front. Small metastatic tumors were considerably more effective in attracting HO-1+ macrophages than larger non-metastatic ones. In clinical samples, accumulation of HO-1+ macrophages was seen at the tumor invasive front, almost exclusively in high-grade tumors, and it correlated with the presence of bone metastases. HO-1+ macrophages, located at the tumor invasive front, were more abundant in bone metastases than in primary tumors. HO-1 expression in bone metastases was variable, and positively correlated with the expression of macrophage markers but negatively correlated with androgen receptor expression, suggesting that elevated HO-1 could be a marker for a subgroup of bone metastases. Together with another recent observation showing that selective knockout of HO-1 in macrophages reduced prostate tumor growth and metastatic capacity in animals, the results of this study suggest that extratumoral HO-1+ macrophages may have an important role in prostate cancer.

    The excited states of {sup 148}Ho and {sup 149}Ho isotopes are studied using gamma-ray and electron spectroscopy in off-beam and in-beam modes following {sup 112,114}Sn({sup 40}Ar,xnyp) reactions. Experiments include measurements of single gamma-rays and conversion electron spectra as well as gamma-gamma, electron-gamma, gamma-t, and gamma-gamma-t coincidences with the use of the OSIRIS-II 12-HPGe array and conversion electron spectrometer. Based on the present results, the level schemes of {sup 148}Ho and {sup 149}Ho are revised and significantly extended, up to about 4 and 5 MeV of excitation energy, respectively. Spin and parity of 5{sup -} are assigned to the 9.59-s isomer in {sup 148}Ho based on conversion electron results. Previously unobserved gamma rays feeding the 10{sup +} isomer in {sup 148}Ho and the 27/2{sup -} isomer in {sup 149}Ho nuclei are proposed. Shell-model calculations are performed. Possible core-excited states in {sup 149}Ho are discussed.

    Although developments in fluid mechanics continue at a heady pace, and are reported in JFM at about 800 pages per month, things in the editorial management of JFM change only slowly. There is a continuity among the JFM Editorial Team and among the policies they espouse and implement that appears to be appreciated by the fluid mechanics community. A major change has, however, occurred from January 1999, in that George Batchelor has, after 43 years as Editor, stepped down from the day-to-day handling of papers and from the formulation of policies and practices, and allowed himself to be named on our masthead as Founding Editor. I say ‘allowed’ because George's initial wish was not to be so named, feeling that this might be seen as an immodest and presumptuous title. But Founding Editor is exactly what George was and is. He launched JFM in May 1956, having persuaded Taylor & Francis to be the publisher and printer, and having enlisted the help of G. F. Carrier, W. C. Griffith and M. J. Lighthill as Associate Editors, and T. Brooke Benjamin and I. Proudman as Assistant Editors. Then, as now, all members of the JFM Editorial Team were to work autonomously in the handling of papers, with complete delegated authority and similar workloads, but all following similar procedures and with similar philosophies, and all under the watchful eye of G. K. B.

    The International Committee of Medical Journal Editors is a leading independent institution providing guidance for the report of biomedical research and health related topics in medical journals. Established in 1978, it is currently constituted by editors of fourteen general medical journals from different countries, plus one representative for the US National Library of Medicine and one representative for the World Association of Biomedical Journal Editors. Since 1978 the Committee provides a document, originally named "Uniform Requirements…", "to help authors, editors, and others involved in peer review and biomedical publishing create and distribute accurate, clear, unbiased medical journal articles". This document has been updated several times and the last version was released in August 2013, now renamed "Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals", available in www.icmje.org and citable as "ICMJE Recommendations". A vast proportion of medical journals, worldwide, have adopted these recommendations as rules. The ICMJE discusses and provides guidance on several relevant aspects including criteria on authorship, peer review, scientific misconduct, conflicts of interest, clinical trials registration, good editorial practices, the relations between editors and journal owners, the protection of individuals subject to medical research, the solvency of electronic publications, among others. The 2013 ICMJE Annual Meeting took place in Santiago, Chile, in November 4 and 5. The photograph shows attendants to the final session.

    Late in fiscal year 2011, the Crew Earth Observations (CEO) team was tasked to upgrade and replace its mission planning and mission operations software systems, which were developed in the Space Shuttle era of the 1980s and 1990s. The impetuses for this change were the planned transition of all workstations to the Windows 7 64-bit operating system and the desire for more efficient and effective use of Satellite Tool Kit (STK) software required for reliable International Space Station (ISS) Earth location tracking. An additional requirement of this new system was the use of the same SQL database of CEO science sites from the SMMS, which was also being developed. STK Integrated Message Production List Editor (SIMPLE) is the essential, all-in-one tool now used by CEO staff to perform daily ISS mission planning to meet its requirement to acquire astronaut photography of specific sites on Earth. The sites are part of a managed, long-term database that has been defined and developed for scientific, educational, and public interest. SIMPLE's end product is a set of basic time and location data computed for an operator-selected set of targets that the ISS crew will be asked to photograph (photography is typically planned 12 to 36 hours out). The CEO operator uses SIMPLE to (a) specify a payload operations planning period; (b) acquire and validate the best available ephemeris data (vectors) for the ISS during the planning period; (c) ingest and display mission-specific site information from the CEO database; (d) identify and display potential current dynamic event targets as map features; (e) compute and display time and location information for each target; (f) screen and select targets based on known crew availability constraints, obliquity constraints, and real-time evaluated constraints to target visibility due to illumination (sun elevation) and atmospheric conditions (weather); and finally (g) incorporate basic, computed time and location information for each selected

    The paramagnetic NMR study of HoM2N@C80-Ih and Ho2MN@C80-Ih nitride cluster fullerenes (M = Sc, Lu, Y) reveals strong dependence of Ho-induced paramagnetic shifts (δpara) in 13C NMR spectra on the size of the diamagnetic metal in the cluster. In particular, the δpara value in HoY2N@C80 is almost doubled in comparison to that in HoSc2N@C80. X-ray magnetic circular dichroism studies show that all Ho-nitride cluster fullerenes have the same magnetic ground state of Ho3+. Point-charge ligand-field splitting calculations show that the increase of the M3+ radius in going from Sc to Y results in a considerable increase of the energy splitting between different Jz states. This leads to a 19% higher magnetic anisotropy of Ho3+ in HoY2N@C80 than in HoSc2N@C80 at 300 K. Variations of the molecular geometry and cluster dynamics with the size of the cluster are found to have even greater influence on δpara values. This work shows that the magnetic properties of the species confined inside the fullerene cages can be tuned using the geometrical factors such as the cluster and the cage size.The paramagnetic NMR study of HoM2N@C80-Ih and Ho2MN@C80-Ih nitride cluster fullerenes (M = Sc, Lu, Y) reveals strong dependence of Ho-induced paramagnetic shifts (δpara) in 13C NMR spectra on the size of the diamagnetic metal in the cluster.

    Scientific journals have a central place in protecting research integrity because published articles are the most visible documentation of research. We used SWOT analysis to audit (S)trengths and (W)eaknesses as internal and (O)pportunities and (T)hreats as external factors affecting journals' responsibility in addressing research integrity issues. Strengths include editorial independence, authority and expertise, power to formulate editorial policies, and responsibility for the integrity of published records. Weaknesses stem from having no mandate for legal action, reluctance to get involved, and lack of training. Opportunities for editors are new technologies for detecting misconduct, policies by editorial organization or national institutions, and greater transparency of published research. Editors face threats from the lack of legal regulation and culture of research integrity in academic communities, lack of support from stakeholders in scientific publishing, and different pressures. Journal editors cannot be the policing force of the scientific community but they should actively ensure the integrity of the scientific record.

    Heme oxygenase (HO) is a cytoprotective enzyme that can be overexpressed in some pathological conditions, including certain cancers. In this work, novel imidazole derivatives were designed and synthesized as inhibitors of heme oxygenase-1 (HO-1) and heme oxygenase-2 (HO-2). In these compounds the imidazole ring, crucial for the activity, is connected to a hydrophobic group, represented by aryloxy, benzothiazole, or benzoxazole moieties, by means of alkyl or thioalkyl chains of different length. Many of the tested compounds were potent and/or selective against one of the two isoforms of HO. Furthermore, most of the pentyl derivatives showed to be better inhibitors of HO-2 with respect to HO-1, revealing a critical role of the alkyl chain in discriminating between the two isoenzymes. Compounds which showed the better profile of HO inhibition were selected and tested to evaluate their cytotoxic properties in prostate and breast cancer cell lines (DU-145, PC3, LnCap, MDA-MB-231, and MCF-7). In these assays, aryloxyalkyl derivatives resulted more cytotoxic than benzothiazolethioalkyl ones; in particular compound 31 was active against all the cell lines tested, confirming the anti-proliferative properties of HO inhibitors and their potential use in the treatment of specific cancers.

    Simultaneous, in situ measurements of OH, HO2, H2O, and O3 from 37-23 km are reported. The partitioning between OH and HO2 and the total HO(x) concentration are compared with expected steady-state values. The ratio of HO2 to OH varies from less than 2 at 36 km to more than 3 at 25 km; in the lower stratosphere this ratio is nearly a factor of two less than predicted. The data are used to calculate HO(x) production and loss rates. The measured HO(x) mixing ratio is consistent with production dominated by the reaction of O(1D) with H2O, and loss controlled by NOy below 28 km and HO(x) above 30 km. The steady-state concentration of H2O2 is inferred from the measured HO2 concentration and calculated photolysis rate. The maximum H2O2 mixing ratio (at 33 km) is predicted to be less than 0.2 ppb.

    The rare earth isotope 163Ho is of interest for neutrino mass measurements. This report describes the isolation of 163Ho from a proton-irradiated dysprosium target and its purification. A Dy metal target was irradiated with 16 MeV protons for 10 h. After target dissolution, 163Ho was separated from the bulk Dy via cation-exchange high performance liquid chromatography using 70 mmol dm–3 α-hydroxyisobutyric acid as the mobile phase. Subsequent purification of the collected Ho fraction was performed to remove the α-hydroxyisobutyrate chelating agent and to concentrate the Ho in a low ionic strength aqueous matrix. The final solution was characterized by MC-ICP-MSmore » to determine the 163Ho/165Ho ratio, 163Ho and the residual Dy content.

  17. Probing the interphase "HO zone" originated by carbon nanotube during catalytic ozonation.

    Carbon nanotube (CNT) is an attractive metal-free catalyst that can be explored in combination with ozone treatment. Using fluorescence microscopy image analysis, we investigated the production of hydroxyl radicals (HO) within the solid-liquid interphase for CNT-mediated catalytic ozonation. The visualized results suggest that HO was vastly generated via catalysis and accumulated within a surface region of the CNT (we defined this region as the interphase "HO zone"). In this region, using 7-hydroxycoumarin as a HO marker, the radical abundance was at least 1000 times higher than that in the aqueous bulk phase. Owing to the observed inhomogeneity of HO, the CNT/ozone system effectively decomposed perfluorooctane sulfonate that was fairly resistant to non-catalytic ozonation, and the decomposition kinetics was not much inhibited by tert-butanol as bulk-phase HO scavenger due to the remaining "HO zone" at surface region available for reaction. A longevity trial revealed the sustained formation of the interphase "HO zone" and strongly indicated that the graphitic structure may optimize the density of surface active sites responsible for the proliferation and local concentration of HO. CNT, with good catalytic efficiency, longevity and stability, is anticipated as the basis of future nanomaterials able to promote HO exposure in ozone treatment for advanced oxidation process.

    Induction of heme oxygenase-1 (HO-1) has been demonstrated to decrease body weight and improve insulin sensitivity in several models of obesity in rodents. To further study the role of HO-1 in adipose tissue, we created an adipose-specific HO-1 knockout mouse model. Male and female mice were fed either a control or a high-fat diet for 30 weeks. Body weights were measured weekly and body composition, fasting blood glucose and insulin levels were determined every six weeks. Adipocyte-specific knockout of HO-1 had no significant effect on body weight in mice fed a high-fat diet but increased body weight in female mice fed a normal-fat diet. Although body weights were not different in females fed a high fat diet, loss of HO-1 in adipocytes resulted in significant alterations in body composition. Adipose-specific HO-1 knockout resulted in increased fasting hyperglycemia and insulinemia in female but not male mice on both diets. Adipose-specific knockout of HO-1 resulted in a significant loss of HO activity and a decrease in the protein levels of adiponectin in adipose tissue. These results demonstrate that loss of HO-1 in adipocytes has greater effects on body fat and fasting hyperglycemia in a sex-dependent fashion and that expression of HO-1 in adipose tissue may have a greater protective role in females as compared to males.

    A kinetic study is made of the reaction of HO2 with NO2, and relative rate coefficients are derived for this reaction and for the reaction of HO2 with NO. It is shown that irradiation of mixtures of N2O-O2-H2 in the presence of small amounts of NO2 at 2139 A and 25 C leads to the consumption of NO2. The results clearly indicate that NO2 is consumed during irradiation to form a product which thermally decomposes to regenerate NO2 thermally and that this product is undoubtedly HONO. In the case of mixtures of N2O-O2-H2 and N2O-O2-H2-CO in the presence of small amounts of both NO and NO2 the NO2 pressure increases initially, reaches a maximum, and then decreases at a constant rate.

  1. The uptake of HO2 radicals to organic aerosols

    HOx (OH + HO2) radicals are responsible for the majority of the oxidation in the troposphere and control the concentrations of many trace species in the atmosphere. There have been many field studies where the measured HO2 concentrations have been smaller than the concentration predicted by model calculations [1,2]. The difference has often been attributed to HO2 uptake by aerosols. Organics are a major component of aerosols accounting for 10 - 70 % of their mass [3]. However, there have been very few laboratory studies measuring HO2 uptake onto organic aerosols [4]. Uptake coefficients (γ) were measured for a range of aerosols using a Fluorescence Assay By Gas Expansion (FAGE) detector combined with an aerosol flow tube. HO2 was injected into the flow tube using a moveable injector which allowed first order HO2 decays to be measured along the flow tube both with and without aerosols. Laboratory generated aerosols were made using an atomiser or by homogeneous nucleation. Secondary organic aerosols (SOA) were made using the Paul Scherrer Institute smog chamber and also by means of a Potential Aerosol Mass (PAM) chamber. The total aerosol surface area was then measured using a Scanning Mobility Particle Sizer (SMPS). Experiments were carried out on aerosols containing glutaric acid, glyoxal, malonic acid, stearic acid, oleic acid and squalene. The HO2 uptake coefficients for these species were measured in the range of γ < 0.004 to γ = 0.008 ± 0.004. Humic acid was also studied, however, much larger uptake coefficients (γ = 0.007 - 0.09) were measured, probably due to the fact that these aerosols contained elevated levels of transition metal ions. For humic acid the uptake coefficient was highly dependent on humidity and this may be explained by the liquid water content of the aerosols. Measurements were also performed on copper doped aerosols containing different organics. An uptake coefficient of 0.23 ± 0.07 was measured for copper doped ammonium sulphate

    Using femtosecond time-resolved resonant magnetic x-ray diffraction at the Ho L3 absorption edge, we investigate the demagnetization dynamics in antiferromagnetically ordered metallic Ho after femtosecond optical excitation. Tuning the x-ray energy to the electric dipole (E 1 , 2 p →5 d ) or quadrupole (E 2 , 2 p →4 f ) transition allows us to selectively and independently study the spin dynamics of the itinerant 5 d and localized 4 f electronic subsystems via the suppression of the magnetic (2 1 3 -τ ) satellite peak. We find demagnetization time scales very similar to ferromagnetic 4 f systems, suggesting that the loss of magnetic order occurs via a similar spin-flip process in both cases. The simultaneous demagnetization of both subsystems demonstrates strong intra-atomic 4 f -5 d exchange coupling. In addition, an ultrafast lattice contraction due to the release of magneto-striction leads to a transient shift of the magnetic satellite peak.

    Ho:Tm:Er:LuAG demonstrated simultaneous laser oscillation associated with two different transitions and different atoms. Two wavelength oscillation, or TWO, can be achieved in a single laser and single resonator. Moreover, the wavelength can be electronically controlled by varying the pump pulse length, Either the short wavelength, the Ho (5)1(sub 7) to (5)1(sub 8) transition at 2.1 microns, or the long wavelength, the Er (4)1(sub 11/2) to (4)1(sub 13/2) transition at 2.7 microns, or both wavelengths simultaneously can be produced without resorting to mechanical intervention. Consequently, a single laser system can easily switch between producing either of these useful wavelengths. Laser operation of both transitions has been characterized and is presented.

    In the continuing effort to develop more efficient man-machine communications methods, touch displays have shown potential as straightforward input systems. The development of software necessary to handle such systems, however, can become tedious. In order to reduce the need for redundant programming, a touch editor has been developed which allows a programmer to interactively define touch-sensitive areas for a graphic display. The information produced during the editing process is written to a data file, which can be accessed easily when needed by an application program. This paper outlines the structure, logic, and use of the editor, as well as the hardware with which it is presently compatible.

    A compact Modular Chemical Descriptor Language (MCDL) chemical structure editor (Java applet) is described. The small size (approximately 200 KB) of the applet allows its use to display and edit chemical structures in various Internet applications. The editor supports the MCDL format, in which structures are presented in compact canonical form and is capable of restoring bond orders as well as of managing atom and bond drawing overlap. A small database of cage and large cyclic fragment is used for optimal representation of difficult-to-draw molecules. The improved algorithm of the structure diagram generation can be used for other chemical notations that lack atomic coordinates (SMILES, InChI).

    Competition of interest may exist at all levels in the medical publication process. Ensuring the integrity of scientific scholarship involves protecting editorial independence, promoting the use of scientific arbitration boards, promoting transparency throughout all stages of publication, and protecting the relationship between the publisher and its editors through an effective legal framework. It is incumbent upon the publisher, editors, authors, and readers to ensure that the highest standards of scientific scholarship are upheld. Doing so will help reduce fraud and misrepresentation in medical research and increase the trustworthiness of landmark findings in science.

In this essay, I discuss the benefits that come with the involvement of active scientists. I enumerate the decisions a monitoring editor has to make, and how he or she goes about making them. Finally, I indicate ways in which authors can help to make the process a smoother and more positive experience.

    Poly(3-hydroxyoctanoic acid)[P(3HO)] and other poly(hydroxyalkanoic acids) PHA are widespread bacterial storage compounds of carbon and reducing power. They are biodegradable to carbon dioxide and water, and both aerobic and anaerobic P(3HB)-degradable bacteria are widely distributed in various ecosytems: soil, activated sludge, lake water and air, sea water, estuarine sediment, and anaerobic sewage sludge. This study describes the isolation and characterization of P(3HO) degrading bacteria: Alcaligenes eutrophus, Comamonas violaceum, Pseudomonas citronellolis, and P. fluorescenes (2 strains). The authors also describe purified P(3HO) depolymerase and compared it to PHB and PHA deploymerases. P(3HO) depolymerase activity was found not only in the sulture supernatant but also in the soluble fraction and membrane fractions of P(3HO) grown cells.39 refs.,5 figs.,3 tabs.

  10. The uptake of HO2 on meteoric smoke analogues

    The kinetics of heterogeneous HO2 uptake onto meteoric smoke particles (MSPs) has been studied in the laboratory using analogues of MSP aerosol entrained into a flow tube. The uptake coefficient, γ, was determined on synthetic amorphous olivine (MgFeSiO4) to be (6.9 ± 1.2) × 10-2 at a relative humidity (RH) of 10%. On forsterite (Mg2SiO4), γ = (4.3 ± 0.4) × 10-3 at RH = 11.6% and (7.3 ± 0.4) × 10-2 at RH = 9.9% on fayalite (Fe2SiO4). These results indicate that Fe plays a more important mechanistic role than Mg in the removal of HO2 from the gas phase. Electronic structure calculations show that Fe atoms exposed at the particle surface provide a catalytic site where HO2 is converted to H2O2 via an Eley-Rideal mechanism, but this does not occur on exposed surface Mg atoms. The impact of this heterogeneous process in the middle atmosphere was then investigated using a whole atmosphere chemistry-climate model which incorporates a microphysical treatment of MSPs. Using a global MSP production rate from meteoric ablation of 44 t/day, heterogeneous uptake (with γ = 0.2) on MSPs significantly alters the HOx budget in the nighttime polar vortex. This impact is highly latitude dependent and thus could not be confirmed using currently available satellite measurements of HO2, which are largely unavailable at latitudes greater than 70°.

Racah (E1, E2, E3), spin-orbit (ξ4f) and configuration interaction (α, β) parameters are calculated and these values are compared for different x values in the glass matrix. Judd-Ofelt intensity parameters (Ω2, Ω4, Ω6) are calculated for all the Ho3+ doped mixed alkali phosphate glasses. From these parameters and from the spectral profiles of the hypersensitive transition structural studies have obtained. Radiative transition probabilities (A), radiative lifetimes (τ), branching ratios (β) and integrated absorption cross-sections (Σ) are obtained from the intensity parameters. Emission cross-sections (σ) are calculated for the two transitions, 5F4, 5S2 → 5I8 and 5F5 → 5I8 of Ho3+ in these two mixed alkali phosphate glasses. Optical band gaps (Eopt) for both direct and indirect transitions are reported.

    The gas-phase hydrogen abstraction reactions of CH(3)O(2) and HO(2) with HO(2) in the presence and absence of a single water molecule have been studied at the CCSD(T)/6-311++G(3d,2p)//B3LYP/6-311G(2d,2p) level of theory. The calculated results show that the process for O(3) formation is much faster than that for (1)O(2) and (3)O(2) formation in the water-catalyzed CH(3)O(2) + HO(2) reaction. This is different from the results for the non-catalytic reaction of CH(3)O(2) + HO(2), in which almost only the process for (3)O(2) formation takes place. Unlike CH(3)O(2) + HO(2) reaction in which the preferred process is different in the catalytic and non-catalytic conditions, the channel for (3)O(2) formation is the dominant in both catalytic and non-catalytic HO(2) + HO(2) reactions. Furthermore, the calculated total CVT/SCT rate constants for water-catalyzed and non-catalytic title reactions show that the water molecule doesn't contribute to the rate of CH(3)O(2) + HO(2) reaction though the channel for O(3) formation in this water-catalyzed reaction is more kinetically favorable than its non-catalytic process. Meanwhile, the water molecule plays an important positive role in increasing the rate of HO(2) + HO(2) reaction. These results are in good agreement with available experiments.

    I am honoured to take on the leadership of Plasma Sources Science and Technology (PSST) as the successor to Professor Mark J Kushner, with whom I have had the pleasure to work on the journal for many years. Under Mark's insightful and energetic leadership over the last six years, PSST has cemented its position as the journal of choice within its subject area and is now one of the most successful journals in the field. In this first issue of 2014, I would like to reflect on some of the events and achievements of 2013. At the start of the year the PSST Editorial Board, recognizing the vital importance of atomic, molecular and optical (AMO) data to low-temperature plasma physics, agreed that PSST would accept papers reporting such new data, generated through both experiment and theory. Jonathan Tennyson joined the Editorial Board to represent this area. In March Anne Bourdon joined the Associate Editor team and has since then played a key part in the journal's review process alongside our other Editors. During the autumn, PSST moved to a new editorial management system. In December Deborah O'Connell was awarded the 2013 Hershkowitz Early Career Award and Review and joins the Editorial Board as of 2014. I would also like to thank Miles Turner for his work in leading the drafting of a guide on the details necessary in the reporting of the results of computer simulations; the main conclusions of this report have been incorporated into the journal policy. Overall 2013 has been another successful year for PSST; paper submissions were up by 8% on the previous year and there was the highest ever number of downloads of PSST papers in one year. Another noteworthy feature of 2013 was the continuing improvement in publication times while maintaining our high standards for acceptance and providing expert feedback coupled with encouragement particularly to younger researchers and groups. Largely as a result of the hard work of our referees and Associate Editors, the average time

    The reaction HO2 + HO2 -> H2O2 + O2(1) has been studied at 100 Torr and 222 K to 295 K. Experiments employing photolysis of Cl2/CH3OH/O2/N2 and F2/H2/O2/N2 gas mixtures to produce HO2 confirmed that methanol enhanced the observed reaction rate. At 100 Torr, zero methanol, k1 = (8.8 +/- 0.9) 10-13 × exp[(210 +/- 26)/T] cm3 molecule-1 s-1 (2σ uncertainties), which agrees with current recommendations at 295 K but is nearly 2 times slower at 231 K. The general expression for k1, which includes the dependence on bath gas density, is k1 = (1.5 +/- 0.2) × 10-12 × exp[(19 +/- 31)/T] + 1.7 × 10-33 × [M] × exp[1000/T], where the second term is taken from the JPL00-3 recommendation. The revised rate largely accounts for a discrepancy between modeled and measured [H2O2] in the lower to middle stratosphere.

Internal slope efficiencies approaching the Stokes limit were produced, and the maximum output power was 2.2W. This result was achieved using a low Ho3+-ion concentration and La3+-ion codoping, which together limit the transfer of energy between excited Ho3+ ions.

    2012-01-01

    The proposal to produce this final commemorative issue for the Journal of Andrology arose during our regular discussions as current editors soon after it was announced that the Journal would complete its own life course and merge into a new publication (to be named Andrology) with the International Journal of Andrology. We considered the momentous occasion to be one that should be celebrated with an enduring tribute in recognition of the Journal's exceptional 33-year existence. Among the various contributions sought for inclusion in this issue, we envisioned an article assembling collected short essays from all living former editors drawing on notable events and highlights, if not less well-known challenges and successes arising during their editorship eras. We thought that any such production of musings, viewpoints, and most of all words of wisdom from those who have had major roles in the direction and accomplishments of the Journal would offer an illuminating read for the society's members and friends and provide all readers another venue to share in and enjoy the Journal's great history. We are enthralled to have gathered these collections, all personal compositions of the former editors-in-chief, and for their effort that has helped us complete this special endeavor we express to them our tremendous gratitude. Serving as the Journal's last editors, we are also grateful to contribute our essay at the very end as part of this joyous chronicle.

    2011-02-01

    So far, there have been no Flash-based web tools available for chemical structure input. The authors herein present a feasibility study, aiming at the development of a compact and easy-to-use 2D structure editor, using Adobe's Flash technology and its programming language, ActionScript. As a reference model application from the Java world, we selected the Java Molecular Editor (JME). In this feasibility study, we made an attempt to realize a subset of JME's functionality in the Flash Molecular Editor (FlaME) utility. These basic capabilities are: structure input, editing and depiction of single molecules, data import and export in molfile format. The result of molecular diagram sketching in FlaME is accessible in V2000 molfile format. By integrating the molecular editor into a web page, its communication with the HTML elements on this page is established using the two JavaScript functions, getMol() and setMol(). In addition, structures can be copied to the system clipboard. A first attempt was made to create a compact single-file application for 2D molecular structure input/editing on the web, based on Flash technology. With the application examples presented in this article, it could be demonstrated that the Flash methods are principally well-suited to provide the requisite communication between the Flash object (application) and the HTML elements on a web page, using JavaScript functions.

    Receptor editing is a mechanism of self-tolerance used in newly generated B cells. The expressed heavy (H) or light (L) chain of an autoreactive receptor is replaced by upstream V genes which eliminate or modify autoreactivity. Editing of anti-DNA receptors has been characterized in anti-DNA transgenic mouse models including 3H9, 3H9/56R, and their revertant 3H9GL. Certain L chains, termed editors, rescue anti-DNA B cells by neutralizing or modifying DNA binding of the H chain. This editing mechanism acts on the natural H chain repertoire; endogenous H chains with anti-DNA features are expressed primarily in combination with editor L chains. We ask whether a similar set of L chains exists in the human repertoire, and if so, do they edit H chains with anti-DNA signatures? We compared the protein sequences of mouse editors to all human L chains and found several human L chains similar to mouse editors. These L chains diminish or veto anti-DNA binding when expressed with anti-DNA H chains. The human H chains expressed with these L chains also have relatively high arginine (Arg) content in the H chain complementarity determining region (H3), suggesting that receptor editing plays a role in establishing tolerance to DNA in humans.

    The University of Southern Mississippi's Center of Higher Learning has developed a Waveform Viewer, Attribute Viewer, and a 3D Editor for use in the CZMIL Point Cloud Manual Editor (CME). The Waveform Viewer displays various channels of CZMIL waveforms within the 2D/3D editor interface of CME. This module provides the user an interactive tool set consisting of a cross sectioning mechanism for the intensity time-bin relationship, waveform file output, and zooming capabilities. The Attribute Viewer provides the data analyst with information to analyze various environmental and spatial parameters that might contribute to errors in the measured points. The 3D Editor offers the benefits of capturing depth outliers; an intuitive visual connectivity with the 2D editor; and the implementation of volumetric directional slice isolation of data outliers.

    relatively recent survey of 2002, it was found that about 60% of 192 authors of clinical practice guidelines reported they had financial connections with the companies whose drugs were under consideration. There is a strong case for making CPGs based not just on effectivity but cost effectivity. The various ramifications of this need to be spelt out. Work of bodies like the Appraisal of Guidelines Research and Evaluation (AGREE) Collaboration and Guidelines Advisory Committee (GAC) are also worth a close look.Even the actions of Foundations that work for disease amelioration have come under scrutiny. The process of setting up 'Best Practices' Guidelines for interactions between the pharmaceutical industry and clinicians has already begun and can have important consequences for patient care. Similarly, Good Publication Practice (GPP) for pharmaceutical companies have also been set up aimed at improving the behaviour of drug companies while reporting drug trialsThe rapidly increasing trend toward influence and control by industry has become a concern for many. It is of such importance that the Association of American Medical Colleges has issued two relatively new documents - one, in 2001, on how to deal with individual conflicts of interest; and the other, in 2002, on how to deal with institutional conflicts of interest in the conduct of clinical research. Academic Medical Centers (AMCs), as also medical education and research institutions at other places, have to adopt means that minimize their conflicts of interest.Both medical associations and research journal editors are getting concerned with individual and institutional conflicts of interest in the conduct of clinical research and documents are now available which address these issues. The 2001 ICMJE revision calls for full disclosure of the sponsor's role in research, as well as assurance that the investigators are independent of the sponsor, are fully accountable for the design and conduct of the trial, have

    Cytoprotective gene heme oxygenase 1 (HO-1) could be induced by nuclear factor E2-related factor 2 (Nrf2) nuclear translocation. The purpose of this study was to determine the role of Brahma-related gene 1 (Brg1), a catalytic subunit of SWI2/SNF2-like chromatin remodeling complexes, in Nrf2/HO-1 pathway activation during hepatic ischemia-reperfusion (HIR). Our results showed that hepatic Brg1 was inhibited during early HIR while Brg1 overexpression reduced oxidative injury in CMV-Brg1 mice subjected to HIR. Moreover, promoter-driven luciferase assay showed that overexpression of Brg1 by adenovirus transfection in AML12 cells selectively enhanced HO-1 gene expression after hypoxia/reoxygenation (H/R) treatment but did not affect the other Nrf2 target gene NQO1. Furthermore, inhibition of HO-1 by the selective HO-1 inhibitor zinc protoporphyria could partly reverse the hepatic protective effects of Brg1 overexpression while HO-1-Adv attenuated AML12 cells H/R damage. Further, chromatin immunoprecipitation analysis revealed that Brg1 overexpression, which could significantly increase the recruitment of Brg1 protein to HO-1 but not NQO1 promoter, was recruited by Nrf2 to the HO-1 regulatory regions in AML12 hepatocytes subjected to H/R. In conclusion, our results demonstrated that restoration of Brg1 during reperfusion could enhance Nrf2-mediated inducible expression of HO-1 during HIR to effectively increase antioxidant ability to combat against hepatocytes damage.

    The crystal structure and conductivity of pyrochlore-like Ho2(Ti2-xHox)O7-x/2 (x=0, 0.01, 0.02, 0.096) ceramics are studied by X-ray diffraction and impedance spectroscopy as a function of temperature and oxygen partial pressure in the temperature range 700-1000 °C. According to the Rietveld refinement data the fraction of cation anti-site pairs in Ho2(Ti1.904Ho0.096)O6.952 sintered at 1400 and 1600 °C is 1.5% and 4.3% respectively. Heat treatment of Ho2(Ti1.904Ho0.096)O6.952 between 1400 and 1600 °C was shown to lead to the formation of pyrochlore-like solid solutions with pure oxide ion conductivities of about 4×10-4 and 1.5×10-3 S/cm at 800 °C, respectively. The ionic transport number is ∼1 at 800 °C and pO2>10 Pa. The electrolyte domain was observed for a wide range of oxygen partial pressures (10 Pa>pO2>10 Pa), which turns the Ho2(Ti1.904Ho0.096)O6.952 ceramic into a typical member of the LANTIOX family, with good oxide ion conductivity.

  12. Scientific value of systematic reviews: survey of editors of core clinical journals.

    Synthesizing research evidence using systematic and rigorous methods has become a key feature of evidence-based medicine and knowledge translation. Systematic reviews (SRs) may or may not include a meta-analysis depending on the suitability of available data. They are often being criticised as 'secondary research' and denied the status of original research. Scientific journals play an important role in the publication process. How they appraise a given type of research influences the status of that research in the scientific community. We investigated the attitudes of editors of core clinical journals towards SRs and their value for publication. We identified the 118 journals labelled as "core clinical journals" by the National Library of Medicine, USA in April 2009. The journals' editors were surveyed by email in 2009 and asked whether they considered SRs as original research projects; whether they published SRs; and for which section of the journal they would consider a SR manuscript. The editors of 65 journals (55%) responded. Most respondents considered SRs to be original research (71%) and almost all journals (93%) published SRs. Several editors regarded the use of Cochrane methodology or a meta-analysis as quality criteria; for some respondents these criteria were premises for the consideration of SRs as original research. Journals placed SRs in various sections such as "Review" or "Feature article". Characterization of non-responding journals showed that about two thirds do publish systematic reviews. Currently, the editors of most core clinical journals consider SRs original research. Our findings are limited by a non-responder rate of 45%. Individual comments suggest that this is a grey area and attitudes differ widely. A debate about the definition of 'original research' in the context of SRs is warranted.

    2013-07-01

    To assess financial, nonfinancial and editors' conflicts of interest (COI) disclosure policies among the most influential biomedical journals publishing original research. We conducted a cross-sectional study of 399 high-impact biomedical journals in 27 biomedical categories of the Journal Citation Reports (JCR) in December 2011. Information relevant to COI and requirements for disclosures that was publicly available on journal websites was collected. While financial COI disclosures were required by 358 (89.7%) and nonfinancial by 280 (70.2%) journals, 155 (38.8%) required editors' disclosures. Journals in the first decile of the JCR classification scored significantly higher than those in the second decile for all disclosure policies. Ninety (22.6%) journals were published by Elsevier and 59 (14.8%) by Wiley-Blackwell, with Elsevier scoring significantly better in financial disclosure policies (P = 0.022). Clinical journals scored significantly higher than basic journals for all disclosure policies. No differences were observed between open-access (n = 25) and nonopen-access (n = 374) journals for any type of disclosure. Somewhat incoherently, authors' disclosure statements were included in some published manuscript in 57.1% of journals without any COI disclosure policies. Authors' financial COI disclosures were required by about 90% of high-impact clinical and basic journals publishing original research. Unlike recent studies showing a significantly lower prevalence of nonfinancial compared with financial disclosures, the former were required by about 70% of journals, suggesting that editors are increasingly concerned about nonfinancial competing interests. Only 40% of journals required disclosure of editors' COI, in conflict with the recommendations of the most influential editors' associations. © 2013 Stichting European Society for Clinical Investigation Journal Foundation.

    To predict the likelihood of hospital-onset Clostridium difficile infection (HO-CDI) based on patient clinical presentations at admission Retrospective data analysis Six US acute care hospitals Adult inpatients We used clinical data collected at the time of admission in electronic health record (EHR) systems to develop and validate a HO-CDI predictive model. The outcome measure was HO-CDI cases identified by a nonduplicate positive C. difficile toxin assay result with stool specimens collected >48 hours after inpatient admission. We fit a logistic regression model to predict the risk of HO-CDI. We validated the model using 1,000 bootstrap simulations. Among 78,080 adult admissions, 323 HO-CDI cases were identified (ie, a rate of 4.1 per 1,000 admissions). The logistic regression model yielded 14 independent predictors, including hospital community onset CDI pressure, patient age ≥65, previous healthcare exposures, CDI in previous admission, admission to the intensive care unit, albumin ≤3 g/dL, creatinine >2.0 mg/dL, bands >32%, platelets ≤150 or >420 109/L, and white blood cell count >11,000 mm3. The model had a c-statistic of 0.78 (95% confidence interval [CI], 0.76-0.81) with good calibration. Among 79% of patients with risk scores of 0-7, 19 HO-CDIs occurred per 10,000 admissions; for patients with risk scores >20, 623 HO-CDIs occurred per 10,000 admissions (P<.0001). Using clinical parameters available at the time of admission, this HO-CDI model demonstrated good predictive ability, and it may have utility as an early risk identification tool for HO-CDI preventive interventions and outcome comparisons.

  15. Superdeformation studies in {sup 150}Tb and {sup 153}Ho

    1995-08-01

    There are now over 40 superdeformed (SD) bands known in the A {approximately} 150 region and in most cases the properties of these bands are understood in terms of single-particle excitations in the absence of pairing. By continuing the search for new SD bands we hope to gain insight into (1) the ordering of the proton and neutron orbitals near the Fermi surface in the SD well, (2) the effects that the alignment of those orbitals has on the moments of inertia, and (3) the collective excitations in the SD well. For {sup 150}Tb, which is one proton and one neutron away from the SD doubly-magic nucleus {sup 152}Dy, it should be possible to study SD bands based on both proton and neutron hole excitations. By adding one proton to the {sup 152}Dy nucleus (i.e. {sup 153}Ho) proton excitations above the Z = 66 shell gap can be studied. These excitations are important as calculations suggested that the proton intruder orbital N = 7 might become occupied. Interactions between this orbital and a N = 5 level may result in softness towards octupole vibrations. High spin states in {sup 150}Th and {sup 153}Ho were populated using the {sup 124}Sn({sup 31}P,5n) and {sup 120}Sn({sup 37}Cl,4n) reactions, respectively. In both cases the early implementation phase of Gammasphere was used to detect the decay gamma rays and over 1 x 10{sup 9} triple and higher fold coincidence events were recorded. In {sup 150}Tb, the data analysis is complete and two new SD bands were identified. The fact that Im{sup (2)} moments of inertia are sensitive to the specific high-N intruder content of the SD bands was used to suggest configurations for the two new bands. A paper reporting these results is being prepared. For {sup 153}Ho, data analysis is still in its early stages.

    The elementary radical-radical reactions that are of such importance in laser, astrophysical, atmospheric, and combustion processes are increasingly open to direct rate measurement. Attention is presently given to the O + HO2 reaction, which has only one exothermic product channel: OH + O2. Isotopic product analysis was conducted spectroscopically using laser-induced fluorescence of OH. It is found that the simple atom-radical reaction takes place by way of the rapid formation and breakup of an unexpected radical intermediate, thereby raising questions as to the formation, thermochemistry, and decomposition of poorly known products in many other radical-radical reaction systems.

    The neutron capture cross sections of Dy163 and Er164 have been measured to analyze the s-process branching at Dy163-Ho163. The reproduction of the s-process abundance of Er164 via this branching is sensitive to temperature kT, neutron density, and electron density n/sub e/. The calculations using information from other branchings on kT and the neutron density n/sub n/ give constraints for n/sub e/ at the site of the s-process.

    In this paper, we study the Chaplygin gas Hořava-Lifshitz quantum cosmology. Using Schutz formalism and Arnowitt-Deser-Misner decomposition, we obtain the corresponding Schrödinger-Wheeler-DeWitt equation. We obtain exact classical and quantum mechanical solutions and construct wave packets to study the time evolution of the expectation value of the scale factor for two cases. We show that unlike classical solutions and upon choosing appropriate initial conditions, the expectation value of the scale factor never tends to the singular point which exhibits the singularity-free behavior of the solutions in the quantum domain.

    We study perturbations of a scalar field cosmology in Hořava-Lifshitz gravity, adopting the most general setup without detailed balance but with the projectability condition. We derive the generalized Klein-Gordon equation, which is sixth-order in spatial derivatives. Then we investigate scalar field perturbations coupled to gravity in a flat Friedmann-Robertson-Walker background. In the sub-horizon regime, the metric and scalar field modes have independent oscillations with different frequencies and phases except in particular cases. On super-horizon scales, the perturbations become adiabatic during slow-roll inflation driven by a single field, and the comoving curvature perturbation is constant.

    HO2 concentrations at two Oregon sites were determined for continuous periods of 36 to 48 hours, using fluorescence assay with gas expansion. At the sea level coastal site, NNW winds prevailed during daytime, and a point measurement of very low total nonmethane hydrocarbon concentration indicated the presence of remote tropospheric air of oceanic origin. At the urban site, HO2 was determined during moderately low ozone pollution levels. At both sites, maximum daily (HO2) was in the range of 1-2 x 10 exp 8/cu cm under clear-sky conditions, with an estimated overall uncertainty of 40 percent. HO2 was detected by continuous low-pressure sampling with flowing chemical conversion to HO, which was detected by laser-excited fluorescence. The instrumental response to HO2 was calibrated by the self-decay of HO2 at atmospheric pressure. Interference in the measured daytime HO2 concentrations by RO2 was estimated at less than 20 percent.

    By conventional melting and quenching methods, 3Yb2O3-0.2Tm2O3-xHo2O3 (wt%, x=0.2~1.2) was doped into an easily fiberized tellurite glass with composition of 78TeO2-10ZnO-12Na2O (mol%) to form YTH-TZN78 glasses. Under 976 nm excitation, the direct sensitizing effect of Yb ions (Yb→Ho) and indirect sensitizing and self-depopulating effects of Tm ions (Yb→Tm→Ho) were found to present intense red upconversion emission at 657 nm (Red, Ho:5F5→5I8) and were responsible for the absence of the usually observed 484 nm emission (Blue, Tm:1G4→3H36). Regardless of the dopant concentration of Ho ions, the intensity of the red emission at 657 nm (Red, Ho:5F5→5I8) is about three times stronger than that of the green one at 543 nm (Green, Ho:5S2→5I8). For this certain red emission at 657 nm, 0.4 wt% Ho2O3-doped YTH-TZN78 glass was found to present the highest emission intensity and is therefore determined as a promising active tellurite glass for red fiber laser development.

    Y3Al4GaO12 (YAGG):(Tm3+, Ho3+) nanoparticles have been synthesized by Pechini sol-gel method and characterised their X-ray diffraction patterns, scanning electron microscope image, energy dispersive and photoluminescence spectra. From XRD results, phase purity and structure have been confirmed. Excitation spectra reveal that 363 nm excitation is suitable to excite the co-doped samples. Under ultraviolet excitation at 363 nm, the characteristic emissions of Tm3+ and Ho3+ ions have been observed in the photoluminescence (PL) spectra. Concentration dependent luminescence and energy transfer between Tm3+ and Ho3+ ions have been studied. The CIE chromaticity coordinates and correlated colour temperature values have been obtained from the emission spectra. Moreover, the emission colour of the YAGG:TmHo nano-powders was slightly shifted to red colour while increasing the Ho concentration and can be tuned from blue/green to white by adjusting the Tm3+/Ho3+ ions concentration. The optimum concentration of Tm3+ and Ho3+ ions were found to be 1:1 ratio in the YAGG host. The optimized single component white light emitting YAGG:TmHo phosphors could be a potential candidate for phosphor-converted white light emitting diode and full colour display applications.

    Hydroxylated polyhalogenated diphenyl ethers (HO-PXDEs) have been recognized as a group of widely detected emerging contaminants in natural waters. Photolysis was proved to be an important transformation pathway for these compounds and their direct phototransformation results in highly toxic dioxins. However, the roles of excited states and reactive oxygen species in the photochemical transformation of these compounds are still unclear. In this study, 2'-HO-2,4,4'-trichlorodiphenyl ether (triclosan) and 2'-HO-2,4,4'-tribromodiphenyl ether (2'-HO-BDE-28) were selected as model compounds to investigate their phototransformation processes. Results showed that the direct photolysis reactions of both triclosan and 2'-HO-BDE-28 occurred via their respective excited singlet states, leading to the generation of dioxins. In addition, the energy and electron transfer reactions between excited states of model compounds and molecular O2 can lead to the generation of (1)O2 and OH, which results in self-sensitized photolysis. We also found that both the k, Φ dioxin yield for anionic triclosan were higher than those of anionic 2'-HO-BDE-28. This study revealed the roles of the excited states in direct photolysis and the generation pathway of reactive oxygen species in self-sensitized photolysis of HO-PXDEs, which is important for understanding the phototransformation mechanisms of HO-PXDEs.

    Ischemia reperfusion (IR) injury occurs in many clinical situations such as organ transplantation and hepatectomies resulting in oxidative stress and immune activation. Heme oxygenase-1(HO-1) is the rate-limiting step in the heme-degradation pathway and has a critical cytoprotective role. Induction of HO-1 improves liver I/R injury. Quercetin, a plant pigment (flavonoid), is an antioxidant and HO-1 inducer. Tin protoporphyrin (SnPP) is a HO-1 inhibitor. This study was designed to investigate the protective effect of quercetin in hepatic I/R injury and the role of HO-1. Wister rats were randomly divided into four groups (sham, I/R, quercetin, and SnPP). Liver ischemia was induced for 45 min then reperfusion was allowed for 1 h. Quercetin and surprisingly SnPP ameliorate the deleterious effect of I/R by reducing the oxidative stress and hepatocyte degeneration. Both agents decreased the elevated inflammatory cytokines and improved the inhibition of the antiapoptotic marker, Bcl2. They induced HO-1 content and expression. Quercetin has better cytoprotective effect than SnPP. These findings suggest that quercetin has a hepatoprotective effect against I/R injury via HO-1 induction and unexpectedly, SnPP showed the similar effect. Quercetin has more prominent protective effect than SnPP because of its superior ability to induce HO-1.

    The recent observation [Wentworth, P., Jones, L. H., Wentworth, A. D., Zhu, X. Y., Larsen, N. A., Wilson, I. A., Xu, X., Goddard, W. A., Janda, K. D., Eschenmoser, A. & Lerner, R. A. (2001) Science 293, 1806–1811] that antibodies form H2O2 from 1O2 plus H2O was explained in terms of the formation of the H2O3 species that in the antibody reacts with a second H2O3 to form H2O2. There have been few reports of the chemistry for forming H2O3, but recently Engdahl and Nelander [Engdahl, A. & Nelander, B. (2002) Science 295, 482–483] reported that photolysis of the ozone–hydrogen peroxide complex in argon matrices leads to significant concentrations of H2O3. We report here the chemical mechanism for this process, determined by using first-principles quantum mechanics. We show that in an argon matrix it is favorable (3.5 kcal/mol barrier) for H2O2 and O3 to form a [(HO2)(HO3)] hydrogen-bonded complex [head-to-tail seven-membered ring (7r)]. In this complex, the barrier for forming H2O3 plus 3O2 is only 4.8 kcal/mol, which should be observable by means of thermal processes (not yet reported). Irradiation of the [(HO2)(HO3)-7r] complex should break the HO–OO bond of the HO3 moiety, eliminating 3O2 and leading to [(HO2)(HO)]. This [(HO2)(HO)] confined in the matrix cage is expected to rearrange to also form H2O3 (observed experimentally). We show that these two processes can be distinguished isotopically. These results (including the predicted vibrational frequencies) suggest strategies for synthesizing H2O3 and characterizing its chemistry. We suggest that the [(HO2)(HO3)-7r] complex and H2O3 are involved in biological, atmospheric, and environmental oxidative processes. PMID:12438699

    The decision to publish the journals Der Schmerz and Narkose und Anaesthesie in 1928 was an important step towards the professionalization of anaesthesiology in Germany. The appearance of both journals, which for economic reasons merged into Schmerz - Narkose - Anaesthesie 1 year later, was initiated and vehemently supported by Jewish physicians. As editors and co-editors they were deeply involved with the editorial tasks of the journals for years from the early beginnings. When the National Socialistic Party took over the government in Germany many of the Jewish colleagues were forced to quit their editorial tasks, were eliminated and replaced by "Arians", they were persecuted and often arrested, forced to emigrate or decided to commit suicide due to inhumane personal circumstances. It is our intention to recall the biography and the terrible fate of the nearly unknown Jewish members of the editorial board of the first German anaesthesia journals. Moreover the biographic sketches promote a continuous discussion about the victims of an inhumane and barbarous ideology.

    Induction of Nrf2-mediated detoxifying/antioxidant enzymes is an effective strategy for cancer chemoprevention. The goal of this study was to examine the role of calcium [Ca(2+)] in regulating a well-known phenolic chemopreventive compound tertiary-butylhydroquinone (tBHQ) activation of Nrf2 and induction of Nrf2 downstream target gene heme-oxygenase (HO-1). tBHQ alone caused Nrf2 nuclear localization and induced HO-1 mRNA and protein expression in a dose-dependent manner. Using RT-PCR and Western blotting, we showed that tBHQ-induced transcription of HO-1 is Ca(2+)-dependent. Chelation of [Ca(2+)](ext) or [Ca(2+)](intra) by EGTA or BAPTA attenuated tBHQ-induced HO-1. Cotreatment of tBHQ with inhibitors of [Ca(2+)]-sensitive protein kinase C and camodulin kinase did not attenuate HO-1 induction. Nuclear translocation of Nrf2 induced by tBHQ was also not affected by treatment of EGTA or BAPTA. Additionally, EGTA and BAPTA treatments decreased basal nuclear phosphorylation of CREB and decreased tBHQ-induced Nrf2-CBP binding and Nrf2 binding to enhancer as well as polymerase II binding to the promoter of HO-1 gene. Furthermore, tBHQ in combination with higher [Ca(2+)](ext) augmented HO-1 induction both in vitro and in vivo, indicating that the modulation of [Ca(2+)](int) could be used as an adjuvant to increase the efficacy of chemopreventive agents. Taken together, our results indicated that in addition to tBHQ-induced oxidative stress-mediated Nrf2 translocation, HO-1 induction by tBHQ also appears to be dependent on a series of Ca(2+)-regulated mechanisms.

    A method is proposed and tested concerning the characterization of antioxidants by means of their reaction with electrogenerated HO radicals in galvanostatic assays with simultaneous O2 evolution, using a Pt anode fairly oxidized. The consumption of a set of species with antioxidant activity, ascorbic acid (AA), caffeic acid (CA), gallic acid (GA) and trolox (T), is described by a first order kinetics. The rate of the processes is limited by the kinetics of reaction with HO radicals and by the kinetics of charge transfer. Information regarding the scavenger activity of antioxidants is obtained by the relative value of the rate constant of the reaction between antioxidants and HO radicals, k(AO,HO)/k(O2). The number of HO radicals scavenged per molecule of antioxidant is also estimated and ranged from 260 (ascorbic acid) to 500 (gallic acid). The method is applied successfully in the characterization of the scavenger activity of ascorbic acid in a green-tea based beverage.

    We have generated a set of thermodynamic and kinetic parameters for the reactions involving HO{sub 2} in the very early stages of benzene oxidation at low temperatures using density functional theory (DFT). In particular, we report the rate constants for the reactions of HO{sub 2} with benzene and phenyl. The calculated reaction rate constant for the abstraction of H-C{sub 6}H{sub 5} by HO{sub 2} is found to be in good agreement with the limited experimental values. HO{sub 2} addition to benzene is found to be more important than direct abstraction. We show that the reactions of HO{sub 2} with the phenyl radical generate the propagating radical OH in a highly exoergic reaction. The results presented herein should be useful in modeling the oxidation of aromatic compounds at low temperatures. (author)

    Magnetic properties of the geometrically frustrated antiferromagnet HoB12 (with T N = 7.4 K) modified by substitution of magnetic Ho atoms through non-magnetic Lu ones are presented and discussed. In this case, in Ho1- x Lu x B12 solid solutions, both chemical pressure resulting from different Lu3+ and Ho3+ radii and magnetic dilution take place with increasing Lu content ( x) that change properties of the system. The received results show strong indication for the existence of a quantum critical point near x = 0.9, which separates the region of magnetic order (starting with HoB12 for x = 0) and the nonmagnetic region (ending with superconducting LuB12 for x = 1).

    The biological effect of Ho3+ on Halobacterium halobium R1 growth was analyzed using the microcalorimetric method. Using the LKB-2277 Bioactivity Monitor with the ampoule method at 37 degrees C, the thermogenic curves of the growth of H. halobium R1 were obtained. Then, the maximum power (P (m)) and the growth rate constants (k) were determined, and the values of P (m) and k were linked to the concentration of Ho3+. In all, the addition of Ho3+ cause a decrease in the maximum heat production and growth rate constants. To confirm the results, the shapes of H. halobium R1 cell addition with Ho3+ using a transmission electron microscope (TEM) were observed. According to the thermogenic curves and TEM photos of H. halobium R1 under different conditions, it is clear that the metabolic mechanism of H. halobium R1 growth has been changed with the addition of Ho3+.

    The upregulation of heme oxygenase-1 (HO-1) is one of the most important mechanisms of cell adaptation to stress. Indeed, the redox sensitive transcription factor Nrf2 is the pivotal regulator of HO-1 induction. Through the antioxidant, antiapoptotic, and antinflammatory properties of its metabolic products, HO-1 plays a key role in healthy cells in maintaining redox homeostasis and in preventing carcinogenesis. Nevertheless, several lines of evidence have highlighted the role of HO-1 in cancer progression and its expression correlates with tumor growth, aggressiveness, metastatic and angiogenetic potential, resistance to therapy, tumor escape, and poor prognosis, even though a tumor- and tissue-specific activity has been observed. In this review, we summarize the current literature regarding the pro-tumorigenic role of HO-1 dependent tumor progression as a promising target in anticancer strategy.

    Numerous theoretical and experimental studies have suggested that HO2 radicals are able to form strong hydrogen bonds with some closed-shell species, which can potentially influence our understanding of HO2 chemistry in the upper troposphere and lower stratosphere. In this study, a laser flash photolysis-tunable diode laser absorption spectroscopy technique has been employed to study the formation of HO2 complexes with formic and acetic acids. At low temperatures, equilibration kinetics have been observed, allowing adduct formation and dissociation rate coefficients to be obtained and adduct binding enthalpies to be determined. This is the first experimental study of the HO2-carboxylic acid complexes and the binding energies are in good agreement with the most recent theoretical estimates. The potential role of HO2-RC(O)OH adducts in atmospheric chemistry will be discussed.

    We consider spatially homogeneous (but generally non-isotropic) cosmologies in the recently proposed Hořava-Lifshitz gravity and compare them to those of general relativity using Hamiltonian methods. In all cases, the problem is described by an effective point particle moving in a potential well with exponentially steep walls. Focusing on the closed-space cosmological model (Bianchi type IX), the mixmaster dynamics is now completely dominated by the quadratic Cotton tensor potential term for a very small volume of the universe. Unlike general relativity, where the evolution toward the initial singularity always exhibits chaotic behavior with alternating Kasner epochs, the anisotropic universe in Hořava-Lifshitz gravity (with parameter λ > 1/3) is described by a particle moving in a frozen potential well with fixed (but arbitrary) energy E. Alternating Kasner epochs still provide a good description of the early universe for very large E, but the evolution appears to be non-ergodic. For very small E there are harmonic oscillations around the fully isotropic model. The question of chaos remains open for intermediate energy levels.

  3. Containment-enhanced Ho:YAG photofragmentation of soft tissues

    1998-01-01

    Laser surgery of soft tissue can exploit the power of brief, intense pulses of light to cause localized disruption of tissue with minimal effect upon surrounding tissue. In particular, studies of Ho:YAG laser surgery have shown that the effects of cavitation upon tissues and bone depend upon the physical composition of structures in the vicinity of the surgical site. For photofragmentation of occluding structures within catheters and other implant devices, it is possible to exploit the particular geometry of the catheter to amplify the effects of photofragmentation beyond those seen in bulk tissue. A Ho:YAG laser was used to photofragment occlusive material (tissue and tissue analogs) contained in glass capillary tubing and catheter tubing of the kind used in ventricular shunt implants for the management of hydrocephalus. Occluded catheters obtained from patient explants were also employed. Selection of operational parameters used in photoablation and photofragmentation of soft tissue must consider the physical composition and geometry of the treatment site. In the present case, containment of the soft tissue within relatively inelastic catheters dramatically alters the extent of photofragmentation relative to bulk (unconstrained) material. Our results indicate that the disruptive effect of cavitation bubbles is increased in catheters, due to the rapid displacement of material by cavitation bubbles comparable in size to the inner diameter of the catheter. The cylindrical geometry of the catheter lumen may additionally influence the propagation of acoustic shock waves that result from the collapse of the condensing cavitation bubbles.

    Using femtosecond time-resolved resonant magnetic x-ray diffraction at the Ho L3 absorption edge, we investigate the demagnetization dynamics in antiferromagnetically ordered metallic Ho after femtosecond optical excitation. Here, tuning the x-ray energy to the electric dipole (E1, 2p → 5d) or quadrupole (E2, 2p → 4f) transition allows us to selectively and independently study the spin dynamics of the itinerant 5d and localized 4f electronic subsystems via the suppression of the magnetic (2 1 3–τ) satellite peak. We find demagnetization time scales very similar to ferromagnetic 4f systems, suggesting that the loss of magnetic order occurs via a similar spin-flipmore » process in both cases. The simultaneous demagnetization of both subsystems demonstrates strong intra-atomic 4f–5d exchange coupling. In addition, an ultrafast lattice contraction due to the release of magneto-striction leads to a transient shift of the magnetic satellite peak.« less

    Today most surgical treatment of spinal deformations is concentrated on invasive mechanical techniques with long operation times and major effects on the patient's mobility. The proposed minimally invasive technique using laser light for tissue ablation offers a possibility of gentle scoliosis treatment. It is thought that an early removal of the epiphysial growth zone on the convex side over several vertebrae results in a straightening of the spine. In a first evaluation, four different laser systems including argon ion, Nd:YAG (Q-switched), Nd:YAG (cw), and Ho:YAG laser were compared with respect to thermal damage to adjacent tissue, ablation rates, efficiency and laser handling. For in-vivo investigation, fresh lamb spine was used. Comparison showed that the Ho:YAG laser is the most appropriate laser for the given goal, providing efficient photoablation with moderate thermal effects on the adjacent tissue. In a second step the proposed minimally invasive operation technique was performed in in-vivo experiments on young foxhounds using 3D- thoracoscopic operation techniques. During these operations temperature mapping was done using fiber-optic fluorescent probes. After 12 months of normal growth the animals were sacrificed and x-ray as well as MRI was performed on the spine. First results show a positive effect of scoliotic growth in two cases. Being able to produce a scoliosis by hemiepiphysiodesis on the vertebra, It is thought that this technique is successful for a straightening of the spine on patients with scoliosis.

    Hexagonal manganites belong to a special group called ferroelectromagnets, in which frustrated antiferromagnetic and ferroelectric orders coexist. These materials attract much attention for the potential applications on transducers, magnetic field sensors, as well as the information storage industry. Hexagonal manganites can be converted to orthorhombic structure at 1000 °C, 4 GPa conditions. The transition can also be realized under high pressure at room temperature, as observed in TmMnO3, YMnO3, LuMnO3, etc. The structure stability of hexagonal manganites is therefore of both fundamental and applied interests. In this paper, X-ray diffraction was performed on HoMnO3 single crystal under pressure up to 43 GPa by using helium as pressure medium. At 35.6 GPa, HoMnO3 converts to another hexagonal phase, whose lattice parameter along c axis reduces to half. The P-V data can be well fitted by 3-order Birch-Murnaghan equation with K0 = 154 GPa and K0' = 4.6.

    Reaction of methyl radicals with hydroperoxy radicals, CH3 + HO2 → products (1) was studied using pulsed laser photolysis coupled to transient UV-vis absorption spectroscopy at 295 K and 1 bar (He). Photolysis of N2O/H2O2/CH4/H2O/He mixtures at 193.3 nm (ArF excimer laser) was used to simultaneously produce methyl radicals and hydroperoxy radicals in reactions of electronically excited oxygen atoms O((1)D) with CH4 and OH radicals with H2O2, respectively. Temporal profiles of CH3 and HO2 were recorded via absorption at 216.4 and 224 nm. The absolute intensity of the photolysis light inside the reactor was determined by an accurate in situ actinometry based on the ozone formation in the presence of molecular oxygen. The measured rate constant of reaction 1 is k1 = (3.7 ± 1.8 × 10(-11) cm(3) molecule(-1) s(-1) (295 K, 1 bar, He).

    Using femtosecond time-resolved resonant magnetic x-ray diffraction at the Ho L3 absorption edge, we investigate the demagnetization dynamics in antiferromagnetically ordered metallic Ho after femtosecond optical excitation. Here, tuning the x-ray energy to the electric dipole (E1, 2p → 5d) or quadrupole (E2, 2p → 4f) transition allows us to selectively and independently study the spin dynamics of the itinerant 5d and localized 4f electronic subsystems via the suppression of the magnetic (2 1 3–τ) satellite peak. We find demagnetization time scales very similar to ferromagnetic 4f systems, suggesting that the loss of magnetic order occurs via a similar spin-flip process in both cases. The simultaneous demagnetization of both subsystems demonstrates strong intra-atomic 4f–5d exchange coupling. In addition, an ultrafast lattice contraction due to the release of magneto-striction leads to a transient shift of the magnetic satellite peak.

    We examine a class of cylindrically symmetric solutions in Hořava-Lifshitz gravity. For the relativistic value of the coupling constant, λ=1, we find the hedgehog-type static black string solution with the nonvanishing radial shift in the Arnowitt-Deser-Misner-type decomposition of the spacetime metric. With zero radial shift, this solution corresponds to the usual Banados-Teitelboim-Zanelli (BTZ) black string in general relativity. However, unlike the general relativity case, the BTZ-type black strings do naturally exist in Hořava-Lifshitz gravity, without the need for any specific source term. We also find a rotating BTZ-type black string solution which requires the nonvanishing radial shift for its very existence. We calculate the mass and the angular momentum of this solution, using the canonical Hamiltonian approach. Next, we discuss the Lemos-type black string, which is inherent in general relativity with a negative cosmological constant, and present the static metric for any value of λ>1/3. Finally, we show that while, for λ=1, the entropy of the Lemos-type black string is given by one quarter of the horizon area, the entropy of the static BTZ-type black string is one half of its horizon area.

    We study gravitational collapse of a spherical fluid in nonrelativistic general covariant theory of the Hořava-Lifshitz gravity with the projectability condition and an arbitrary coupling constant λ, where |λ-1| characterizes the deviation of the theory from general relativity in the infrared limit. The junction conditions across the surface of a collapsing star are derived under the (minimal) assumption that the junctions be mathematically meaningful in terms of distribution theory. When the collapsing star is made of a homogeneous and isotropic perfect fluid, and the external region is described by a stationary spacetime, the problem reduces to the matching of six independent conditions. If the perfect fluid is pressureless (a dust fluid), it is found that the matching is also possible. In particular, in the case λ=1, the external spacetime is described by the Sch-(anti-)de Sitter solution written in Painlevé-Gullstrand coordinates. In the case λ≠1, the external spacetime is static but not asymptotically flat. Our treatment can be easily generalized to other versions of Hořava-Lifshitz gravity or, more generally, to any theory of higher-order derivative gravity.

    We have studied both theoretically and experimentally the energy transfer processes in YbLiF4:Ho3+ (0.4%) and YbLiF4:Ho3+ (0.4%),Tm3+ (10%) crystals and in the series of crystals KYb(WO4)2:Tm3+,Ho3+ (0.4%) with the thulium concentration 5; 10; and 20%. The population kinetics of the 5I7 holmium level was studied under the 1.047 micrometers Q-switched YLF:Nd3+ laser pumping. The efficiency of energy transfer processes in Ho3+ doped crystals, codoped with Yb3+ and Tm3+, was demonstrated. With an YbLiF4:Ho3+ (0.4%) laser rod we have obtained lasing at 2.06 micrometers with the total efficiency of 4.8% and the slope efficiency of 11%. In the KYb(WO4)2:Tm3+ (10%),Ho3+ (0.4%) crystal, lasing was obtained for the first time at 2 micrometers . The pumping threshold being approximately 150 mJ, total efficiency 6% and slope efficiency 9.7% was achieved.

  13. Induction of heme-oxygenase-1 (HO-1) does not enhance adiponectin production in human adipocytes: Evidence against a direct HO-1 - Adiponectin axis.

    Adiponectin is a salutary adipokine and hypoadiponectinemia is implicated in the aetiology of obesity-related inflammation and cardiometabolic disease making therapeutic strategies to increase adiponectin attractive. Emerging evidence, predominantly from preclinical studies, suggests induction of heme-oxygenase-1 (HO-1) increases adiponectin production and reduces inflammatory tone. Here, we aimed to test whether induction of HO-1 enhanced adiponectin production from mature adipocytes. Treatment of human adipocytes with cobalt protoporphyrin (CoPP) or hemin for 24-48 h increased HO-1 expression and activity without affecting adiponectin expression and secretion. Treatment of adipocytes with TNFα reduced adiponectin secretion and increased expression and secretion of additional pro-inflammatory cytokines, IL-6 and MCP-1, as well as expression of sXBP-1, a marker of ER stress. HO-1 induction failed to reverse these effects. These results demonstrate that induction of HO-1 does not directly enhance adiponectin production or ameliorate the pro-inflammatory effects of TNFα and argue against a direct HO-1 - adiponectin axis.

    This program allows the user to edit files using a completely natural method. You don`t need a lot of time to learn how to use this program; it`s as simple as using a typewriter. Even while you are reading this report you can start editing files. Although it is as simple as using a typewriter, this is a full screen editor, so that you can overwrite (replace) anything, delete or insert characters or lines, copy or move lines, find or change anything. All of this can be done without using any complicated combinations of key strokes (as you are forced to memorize with other editors). This program is written in standard FORTRAN. Although it was designed and implemented on an IBM-PC, it can be easily adapted for use on virtually any graphics terminal.

    Most of us learned about the extraordinary macroalgal bloom in the Yellow Sea through press reports previous to the 2008 Olympic competition in China. I was made aware of the extensive research efforts on this remarkable case of human-prompted, large-scale environmental change by discussions with Dr. Dongyan Liu during the 2012 ECSA conference in Venice. It soon became evident that it would be of great interest to the international audience to bring together results from the many different research projects on different aspects of this topic, taking place in different institutions and agencies. I therefore suggested that a committee of guest editors for the Issue be organized. The guest editors were charged with inviting the many researchers involved in work on the different aspects of the "green tide" phenomenon to contribute articles, request reviews of the submissions, and with helping me in editing the submissions.

    The Navier-Stokes computer is a parallel computer designed to solve Computational Fluid Dynamics problems. Each processor contains several floating point units which can be configured under program control to implement a vector pipeline with several inputs and outputs. Since the development of an effective compiler for this computer appears to be very difficult, machine level programming seems necessary and support tools for this process have been studied. These support tools are organized into a graphical program editor. A programming process is described by which appropriate computations may be efficiently implemented on the Navier-Stokes computer. The graphical editor would support this programming process, verifying various programmer choices for correctness and deducing values such as pipeline delays and network configurations. Step by step details are provided and demonstrated with two example programs.

    Review articles comprehensively covering a specific topic are crucial for successful research and academic projects. Most editors consider review articles for special and regular issues of journals. Writing a review requires deep knowledge and understanding of a field. The aim of this review is to analyze the main steps in writing a narrative biomedical review and to consider points that may increase the chances of success. We performed a comprehensive search through MEDLINE, EMBASE, Scopus, and Web of Science using the following keywords: review of the literature, narrative review, title, abstract, authorship, ethics, peer review, research methods, medical writing, scientific writing, and writing standards. Opinions expressed in the review are also based on personal experience as authors, peer reviewers, and editors.

    A growing body of literature has identified potential problems that can compromise the quality, fairness, and integrity of journal peer review, including inadequate review, inconsistent reviewer reports, reviewer biases, and ethical transgressions by reviewers. We examine the evidence concerning these problems and discuss proposed reforms, including double-blind and open review. Regardless of the outcome of additional research or attempts at reforming the system, it is clear that editors are the linchpin of peer review, since they make decisions that have a significant impact on the process and its outcome. We consider some of the steps editors should take to promote quality, fairness and integrity in different stages of the peer review process and make some recommendations for editorial conduct and decision-making.

  19. Influencing health debates through letters to the editor: the case of male circumcision.

    2009-04-01

    In this article I use the case of male circumcision (MC) to examine how grassroots activists, medical professionals, other stakeholders, and ordinary people employ letters to the editor (LTEs) to influence public health debates. I also show how journalistic practices affect the use of LTEs. Seventy LTEs about MC from U.S. newspapers between 1985 and 2006 are analyzed using qualitative methods. Pro-MC, anti-MC, and neutral LTE writers supported their stances on similar grounds, described adversaries as biased, and stressed medical and scientific authority. Yet only MC advocates and neutralists trivialized MC and declined to justify their stances, suggesting distinctive dynamics for LTEs about widely accepted practices. The prevalence of debated practices and activists' efforts to piggyback on related issues also affect LTE content. Editors chose LTEs to address readers' critiques, enact news values like balance and controversy, and showcase writers with strong claims to legitimacy, thereby mediating public health debates.

    To determine the progress women have made in the last 20 years in terms of contributions to the knowledge base (i.e., authorship) and reputations as leading contributors (i.e., appointments as editors and editorial board members) in educational psychology, we analyzed data from six journals: the American Educational Research Journal, Contemporary Educational Psychology, the Educational Psychologist, Educational Psychology Review, the Journal of Experimental Education, and the Journal of Educational Psychology. Results indicated that (a) women's progress in terms of authorships could be predicted by their increasing representation as educational psychologists, (b) opportunities for females to become editorial board members seem to be getting better, and (c) opportunities for females to become editors seem to be getting worse.
