Full Text Available This paper describes an indicator to evaluate the performance of the infrastructure of sidewalks and public spaces, based on the expectations and perceived needs of wheelchair users, aiming to define accessible routes along urban road networks. The indicator considers variables that describe aspects of comfort and safety for disabled wheelchair users, weighted according to the perception of such users. The application of the indicator in the evaluation of the downtown area of a medium-sized Brazilian city confirmed the hypothesis that there are no accessible routes and helped identify locations where interventions or modifications of already implemented improvements are required to enable the wheelchair user to circulate easily through the city.

People who are blind or visually impaired face difficulties using a growing array of everyday appliances because they are equipped with inaccessible electronic displays. We report developments on our "Display Reader" smartphone app, which uses computer vision to help a user acquire a usable image of a display and have the contents read aloud, to address this problem. Drawing on feedback from past and new studies with visually impaired volunteer participants, as well as from blind accessibility experts, we have improved and simplified our user interface and have also added the ability to read seven-segment digit displays. Our system works fully automatically and in real time, and we compare it with general-purpose assistive apps such as Be My Eyes, which recruit remote sighted assistants (RSAs) to answer questions about video captured by the user. Our discussions and preliminary experiment highlight the advantages and disadvantages of fully automatic approaches compared with RSAs, and suggest possible hybrid approaches to investigate in the future.
Background The challenge in extracting genome-wide chromatin features from limiting clinical samples poses a significant hurdle in identification of regulatory marks that impact the physiological or pathological state. Current methods that identify nuclease accessible chromatin are reliant on large amounts of purified nuclei as starting material. This complicates analysis of trace clinical tissue samples that are often stored frozen. We have developed an alternative nuclease based procedure to bypass nuclear preparation to interrogate nuclease accessible regions in frozen tissue samples. Results Here we introduce a novel technique that specifically identifies Tissue Accessible Chromatin (TACh). The TACh method uses pulverized frozen tissue as starting material and employs one of the two robust endonucleases, Benzonase or Cyansase, which are fully active under a range of stringent conditions such as high levels of detergent and DTT. As a proof of principle we applied TACh to frozen mouse liver tissue. Combined with massive parallel sequencing TACh identifies accessible regions that are associated with euchromatic features and accessibility at transcriptional start sites correlates positively with levels of gene transcription. Accessible chromatin identified by TACh overlaps to a large extend with accessible chromatin identified by DNase I using nuclei purified from freshly isolated liver tissue as starting material. The similarities are most pronounced at highly accessible regions, whereas identification of less accessible regions tends to be more divergence between nucleases. Interestingly, we show that some of the differences between DNase I and Benzonase relate to their intrinsic sequence biases and accordingly accessibility of CpG islands is probed more efficiently using TACh. Conclusion The TACh methodology identifies accessible chromatin derived from frozen tissue samples. We propose that this simple, robust approach can be applied across a broad range of

Current European pharmaceutical legislation is not adequate to meet advances in science and technologies that will lead to rapid development of custom-made medicines. Using existing legislation for custom-made medical devices as a template and anti-sense oligonucleotides as model medicinal products, we propose new European pharmaceutical legislation to permit timely access to custom-made anti-sense oligonucleotide medicinal products. The proposals may be more widely applicable to other medicinal products. © 2013 The British Pharmacological Society.

RAPID is a system capable of providing convenient digital analysis of video data in real-time. It has two modes of operation. The first allows for continuous digitization of an EIA RS-170 video signal. Each frame in the video signal is digitized and written in 1/30 of a second into RAPID's internal memory. The second mode leaves the content of the internal memory independent of the current input video. In both modes of operation the image contained in the memory is used to generate an EIA RS-170 composite video output signal representing the digitized image in the memory so that it can be displayed on a monitor.

To ensure that this system works, each staff member makes an entry into the computer or on the master chart when an item is taken from the supply area. He or she is also expected to check for outdated instrumentation and proper placement on the shelf. The coding system has increased the staff's organization and productivity. It has been successful because it uses a numerical system instead of a memory-based system, and because all instrumentation are categorized and stored according to specialty. The simplicity of the system that allows for quicker access to instrumentation also makes it inexpensive to implement.

Research about accessibility to medicines through household surveys is very important in order to verify the reality and effectiveness of interventions done to increase the access of the population to the medications. Unfortunately, such studies, on top of being very few, have methodological problems, which mostly result from a lack of uniformity in the operational definitions of access and the differentiation with the dimensions of accessibility. The aim of this paper is to propose setting a difference between both terms. We propose an operational definition of access to medications as the process of verification of the purchase of a drug by a patient, independently from many factors that can affect this process. The term "usability of drugs" is introduced, defining it operationally as aimed at measuring the dimensions of the accessibility to the medications: physical availability, affordability, geographical accessibility, acceptability (or satisfaction).

Palliating symptoms of advanced and metastatic cancers are one of the most common indications for radiation therapy (RT), and the demand for palliative RT is increasing. Dedicated rapid access palliative RT programs improve access to care, and can deliver RT in a more efficient and evidence-based manner than standard RT programs. In this narrative review, we discuss the role of palliative RT in comprehensive cancer care, and challenges that have faced patients trying to access it. We describe how rapid access programs developed to address these challenges and provide an overview of dedicated programs worldwide. Finally, we show how these programs can serve as models for multidisciplinary care and education, and sources of exciting research opportunities in clinical care and advanced technologies.

Full Text Available Abstract Proliferative verrucous leukoplakia (PVL is a rare oral leukoplakia and has four features such as chronic proliferation, multiple occurrences, refractoriness to treatment and high rate of malignant transformation. As mentioned above, most PVL cases processed to malignancy over many years, sometimes 20 years. However, this report described a case of rapid progress, which had malignant transformation in a short period. Additionally, the aetiology of PVL was discussed and immunity was proposed as the possible cause.
Full Text Available Abstract Background This article centers around a proposal outlining how research universities could leverage their intellectual property to help close the access gap for health innovations in poor countries. A recent deal between Emory University, Gilead Sciences, and Royalty Pharma is used as an example to illustrate how 'equitable access licensing' could be put into practice. Discussion While the crisis of access to medicines in poor countries has multiple determinants, intellectual property protection leading to high prices is well-established as one critical element of the access gap. Given the current international political climate, systemic, government-driven reform of intellectual property protection seems unlikely in the near term. Therefore, we propose that public sector institutions, universities chief among them, adopt a modest intervention – an Equitable Access License (EAL – that works within existing trade-law and drug-development paradigms in order to proactively circumvent both national and international obstacles to generic medicine production. Our proposal has three key features: (1 it is prospective in scope, (2 it facilitates unfettered generic competition in poor countries, and (3 it centers around universities and their role in the biomedical research enterprise. Two characteristics make universities ideal agents of the type of open licensing proposal described. First, universities, because they are upstream in the development pipeline, are likely to hold rights to the key components of a wide variety of end products. Second, universities acting collectively have a strong negotiating position with respect to other players in the biomedical research arena. Finally, counterarguments are anticipated and addressed and conclusions are drawn based on how application of the Equitable Access License would have changed the effects of the licensing deal between Emory and Gilead.

Ultrasound assessment of patients in shock is becoming the standard of care in emergency and critical care settings worldwide. One of the most common protocols used for this assessment is the rapid ultrasound in shock (RUSH) examination. The RUSH protocol is a rapid evaluation of cardiac function, key vascular structures, and likely sources of hypotension. Stroke volume is an established important value to assess in the setting of shock, allowing the provider to predict the patient's response to treatment. However, the calculation of stroke volume or its surrogates is not part of any protocol, including RUSH. We propose the addition of ultrasound calculation of stroke volume or surrogates to the RUSH protocol and provide support for its utility and relative ease of calculation. The resulting product would be the RUSH velocity-time integral protocol. © 2015 by the American Institute of Ultrasound in Medicine.

There is widespread recognition that the existing global systems for innovation and access to medicines need reform. Billions of people do not have access to the medicines they need, and market failures prevent new drugs from being developed for diseases that primarily affect the global poor. The World Health Organization's Consultative Expert Working Group on Research and Development: Financing and Coordination (CEWG) analyzed numerous proposals for reform. The aim of this article is to build on these previous inquiries. We conducted a structured analysis that grouped proposals into five broad opportunities for global policy reform to help researchers and decision makers to meaningfully evaluate each proposal in comparison with similar proposals. Proposals were also analyzed along three important dimensions-potential health impact, financial implications, and political feasibility-further facilitating the comparison and application of this information. Upon analysis, no one solution was deemed a panacea, as many (often competing) considerations need to be taken into account. However, some proposals, particularly product development partnership and prizes, appeared more promising and feasible at this time and deserve further attention. More research is needed into the effectiveness of these mechanisms and their transferability across jurisdictions. Copyright © 2014 The Authors. Published by Elsevier Inc. All rights reserved.

We report on the evolution of the rapid access neurology clinic (established in 1995) at Addenbrooke's Hospital, Cambridge. Annualised attendance data demonstrate an ever increasing demand, with primary headache disorders now accounting for more than 40% of referrals. Secondary causes of headache (including intracranial tumours, idiopathic intracranial hypertension, carotid or vertebral artery dissection and subdural haematomas) remain infrequent. In all such cases, there were additional diagnostic clues. The number of patients referred with problems related to chronic neurological diseases has fallen considerably, reflecting the roles of specialist nurses and clinics. Imaging investigation of choice shifted from computerised tomography scan (45 to 16%) towards magnetic resonance imaging (17 to 47%). Management is increasingly on an outpatient basis, often without the need for a follow-up appointment. The experience presented here should inform further development of rapid access neurology clinics across the UK and suggests the need for acute headache services, in line with those for transient ischaemic attack and first seizure. © Royal College of Physicians 2015.

The proposal addresses the wireless optical broadband access networks architecture by deploying mesh network structure, which could be the alternatives to FTTx (home or node, etc) architecture. Instead of fiber used as the transmission medium in the distribution plant, here we suggest to use the free space optic links to construct the optical mesh network. The practical connections are depending on the services provided. For Video-on-Demand (VoD) service, the final connection could use twisted pair by integrated VDSL technology. The distributed bandwidth can reach 25-32 Mbps per end user. In this paper we give some comments for designing a broadband access network using optical mesh network structure. It includes the traffic estimation, transmission network design and access node design suggestions.

Environmental impacts of small scale projects are often assessed poorly, or not assessed at all. This paper examines the usability of the Rapid Impact Assessment Matrix (RIAM) as a tool to prioritize project proposals for small scale water restoration projects in relation to proposals' potential to improve the environment. The RIAM scoring system was used to assess and rank the proposals based on their environmental impacts, the costs of the projects to repair the harmful impacts, and the size of human population living around the sites. A four-member assessment group (The expert panel) gave the RIAM-scores to the proposals. The assumed impacts of the studied projects at the Eastern Finland water systems were divided into the ecological and social impacts. The more detailed assessment categories of the ecological impacts in this study were impacts on landscape, natural state, and limnology. The social impact categories were impacts to recreational use of the area, fishing, industry, population, and economy. These impacts were scored according to their geographical and social significance, their magnitude of change, their character, permanence, reversibility, and cumulativeness. The RIAM method proved to be an appropriate and recommendable method for the small-scale assessment and prioritizing of project proposals. If the assessments are well documented, the RIAM can be a method for easy assessing and comparison of the various kinds of projects. In the studied project proposals there were no big surprises in the results: the best ranks were received by the projects, which were assumed to return watersheds toward their original state.

To realize economical optical burst signal receivers for the Optical Network Unit (ONU) of the Ethernet Optical Switched Access Network (E-OSAN), we previously implemented optical burst receivers with AC-coupling and DC-coupling using off-the-shelf components, and showed that the former offers better performance. This paper proposes a new optical burst signal receiver that uses the transfer function, Gn(s) =1-Hn(s), where Hn(s) denotes a Bessel filter transfer function of order n. We also present a method for designing the proposed receiver and clarify that it has better performance than the conventional AC-coupling one. We then present an LCR circuit synthesis of Gn(s), which is necessary to actually implement a burst receiver based on the proposal.

This clinic was set up to provide diagnosis and treatment, and to coordinate investigative procedures, where necessary, into the underlying causes of anemia. Initially piloted with anemic preoperative orthopedic patients, the clinic now treats a wide range of conditions, deriving from both internal and external referrals. Treatment includes dietary advice, supplementation with iron, vitamin B12 and folate, and blood transfusion. Most patients at the RAAC need iron replacement, the majority of which require intravenous (IV iron. Therefore the first-line IV iron-administration protocol is carefully considered to ensure viability of the service and patient satisfaction. Four IV irons available in the UK are discussed, with explanation of the benefits and drawbacks of each product and the reasoning behind the IV iron choice at different stages of the RAAC's development. Costs to the service, affected by IV iron price and administration regimen, are considered, as well as the product's contraindications. Finally, the authors reflect on the success of the RAAC and how it has improved patients' quality-of-treatment experience, in addition to benefiting the hospital and National Health Service in achieving specific health-care mandates and directives. Drawing from the authors' experiences, recommendations are given to assist others in setting up and providing a successful rapid-access anemia service or similar facility.Keywords: hemoglobin, iron deficiency, ferric carboxymaltose, iron sucrose, iron dextran, iron isomaltoside
Full Text Available Abstract Background Rapid Access Outpatient Units (RAOUs have been suggested as an alternative to hospital inpatient units for the management of some acutely unwell children. These units can provide ambulatory care, delivered close to home, and may prevent unnecessary hospital admission. There are no qualitative data on the views of primary care practitioners regarding these types of facilities. The aim of the study was to explore the opinions of primary care practitioners regarding a newly established RAOU. Methods The RAOU was established locally at a district general hospital when inpatient beds were closed and moved to an inpatient centre, based six miles away at the tertiary teaching hospital. Qualitative, practice based group interviews with primary care practitioners (general practitioners (GPs, nurse practitioners and practice nurses on their experiences of the RAOU. The data collection consisted of three practice based interviews with 14 participants. The interviews were recorded and transcribed verbatim. Thematic content analysis was used to evaluate the data. Results There was positive feedback regarding ease of telephone access for referral, location, and the value of a service staffed by senior doctors where children could be observed, investigated and discharged quickly. There was confusion regarding the referral criteria for the assessment unit and where to send certain children. A majority of the practitioners felt the utility of the RAOU was restricted by its opening hours. Most participants felt they lacked sufficient information regarding the remit and facilities of the unit and this led to some uneasiness regarding safety and long term sustainability. Conclusion Practitioners considered that the RAOU offered a rapid senior opinion, flexible short term observation, quick access to investigations and was more convenient for patients. There were concerns regarding opening hours, safety of patients and lack of information about

Rapid access carotid endarterectomy (RACE) is the gold standard for stroke prevention in symptomatic patients with 50-99% internal carotid artery stenosis. Diagnosis and referral of eligible patients may be delayed by disruption to local health services. The aim of this study was to evaluate whether service provision was maintained at an appropriate standard (carotid endarterectomy (CEA) at a tertiary hospital between January 2006 and December 2014 were identified. The timeline from initial presentation to carotid imaging, vascular review and surgery was mapped. The post-earthquake period was defined between 22nd of February 2011 until July 2012. Of the 404 patients that underwent CEA during the above period, 62 patients presented during the post-earthquake period and these patients comprised the primary study group. The median time between presentation and CEA was nine days. In all, 47 patients had CEA within two weeks from the index event. The number of CEA procedures doubled since 2009. Despite many challenges following a major natural disaster, delivery of RACE has been maintained at an acceptable standard. Some delays persist and these remain areas for improvement in future.
We examined the outcomes of the first 500 patients referred to a dedicated Rapid Access Lung Cancer Clinic. A total of 206 patients (41.2%) were diagnosed with a thoracic malignancy; 179 had primary lung cancer and 27 had secondary or other thoracic cancers. Pulmonary nodules requiring ongoing surveillance were found in a further 79 patients (15.8%). Of those patients found to have primary lung cancer, 24 (13.4%) had Small Cell and 145 (81%) had Non Small Cell Lung Cancer. In patients with Non small cell tumours, 26 (21.1%) were stage 1, 14 (11.4%) stage II, 37 (30.1%) stage III and 46 (37.4%) stage IV at diagnosis. For the 129 patients (72%) in whom the thoracic MDT recommended active treatment, primary therapy was surgical resection in 44 (24.6%), combined chemoradiation in 31 patients (17.3%), chemotherapy alone in 39 (21.8%) and radiation in 15 (8.4%).

Cancer patients may find it challenging to access timely advice and care. We evaluated the improvement in delivering ambulatory care in establishing a Rapid Assessment Clinic (RAC) in a cancer center. Patients receiving chemotherapy who presented for assessment at the RAC from September 2013 to June 2014 were included for review. Patient demographics, tumor characteristics, presenting complaints, time to assessment, total time spent at the RAC and assessment outcome were extracted. Similar data for cancer patients presented to the emergency department (ED) but were appropriate for RAC assessment from February 2012 to August 2012 were reviewed for comparison. For patients with febrile neutropenia, time to empirical antibiotic therapy was also reviewed and analyzed. Comparing to ED presentation (n = 152), patients reviewed at the RAC (n = 217) had a shorter waiting time to medical review (28.5 vs 40 min, P = 0.12), shorter total time spent for review (3.1 vs 9.7 hrs, P care, resulting in a lower rate of hospital admission and inpatient length of stay for cancer patients. There was, however, no difference in the management of febrile neutropenia. © 2016 John Wiley & Sons Australia, Ltd.

In the present proposal, the publishers' subscription income from multiple institutions is replaced by an "author-side" funding. Journals are paid through contracts between publishers and a single financial partner, the "Sponsoring Consortium for Open Access Publishing in Particle Physics" (SCOAP3). SCOAP3 is envisioned as a global network of funding agencies, research laboratories, and libraries that will contribute the necessary funding; each SCOAP3 partner will recover its contribution from the cancellation of journal subscriptions. This model avoids the obvious disadvantage of authors being directly charged for the OA publication of their articles, which is perceived as an even higher barrier than subscription charges, in particular for theoretical physicists from small institutions who account for the vast majority of HEP papers. The financing and governance of SCOAP3 will follow as much as possible the example of the memoranda of understanding governing large research collaborations. Its partners will c...
Full Text Available Abstract Background Within many parts of the country, the NHS is undertaking reconfiguration of services. Such proposals can prove a tipping point and provoke public protest, often with significant involvement of local and national politicians. We undertook a rapid Health Impact Assessment (HIA of a proposed reconfiguration of maternity services in Huddersfield and Halifax in England. The aim of the HIA was to help the PCT Boards to assess the reconfiguration's possible consequences on access to maternity services, and maternal and infant health outcomes across different socio-economic groups in Kirklees. We report on the findings of the HIA and the usefulness of the process to decision making. Methods This HIA used routine maternity data for 2004–2005 in Huddersfield, in addition to published evidence. Standard HIA techniques were used. Results We re-highlighted the socio economic differences in smoking status at booking and quitting during pregnancy. We focused on the key concerns of the public, that of adverse obstetric events on a Midwife Led Unit (MLU with distant obstetric cover. We estimate that twenty percent of women giving birth in a MLU may require urgent transfer to obstetric care during labour. There were no significant socio economic differences. Much of the risk can be mitigated though robust risk management policies. Additional travelling distances and costs could affect lower socio-economic groups the greatest because of lower car ownership and geographical location in relation to the units. There is potential that with improved community antenatal and post natal care, population outcomes could improve significantly, the available evidence supports this view. Conclusion Available evidence suggests that maternity reconfiguration towards enhanced community care could have many potential benefits but carries risk. Investment is needed to realise the former and mitigate the latter. The usefulness of this Health Impact Assessment

Southwest Virginia is a rural, low-income region with a relatively small dentist workforce and poor oral health outcomes. The opening of a dental school in the region has been proposed by policy-makers as one approach to improving the size of the dentist workforce and oral health outcomes. A policy simulation was conducted to assess how a hypothetical dental school in rural Southwest Virginia would affect the availability of dentists and utilization levels of dental services. The simulation focuses on two channels through which the dental school would most likely affect the region. First, the number of graduates who are expected to remain in the region was varied, based on the extensiveness of the education pipeline used to attract local students. Second, the number of patients treated in the dental school clinic under different dental school clinical models, including the traditional model, a patient-centered clinic model and a community-based clinic model, was varied in the simulation to obtain a range of additional dentists and utilization rates under differing dental school models. Under a set of plausible assumptions, the low yield scenario (ie private school with a traditional clinic) would result in three additional dentists residing in the region and a total of 8090 additional underserved patients receiving care. Under the high yield scenario (ie dental pipeline program with community based clinics) nine new dentists would reside in the region and as many as 18 054 underserved patients would receive care. Even with the high yield scenario and the strong assumption that these patients would not otherwise access care, the utilization rate increases to 68.9% from its current 60.1%. While the new dental school in Southwest Virginia would increase the dentist workforce and utilization rates, the high cost combined with the continued low rate of dental utilization suggests that there may be more effective alternatives to improving oral health in rural areas

The National Department of Transport started a programme to upgrade public transport systems throughout South Africa in 2008, which included the upgrading of transport systems for host cities of the 2010 World Cup. This was the first time there was a clear commitment to produce universally accessible public transport systems in South Africa. The requirement to achieve universal access was reinforced by National Treasuries stipulation, that universal access was a precondition for the approval of all funding for these projects. In the absence of any specific legislation in the transport sector to address universal access and the South African National Building Regulations and the associated deemed to satisfy code, South African National Standard (SANS) 10400 Part S: "Facilities for Persons with Disabilities", providing the only associated standards, there has been a need to revisit traffic engineering codes. This has created an opportunity to look at the functionality and safety of commuters, especially those who have functional limitations, at traffic intersections and midblock pedestrian crossings, especially as the commuters have to access predominately median located Bus Rapid Transport (BRT) trunk stations. Included in the specific areas of focus that impact on the issues of pedestrian safety, has been the application and functionality of tactile wayfinding and warning surfaces and other support systems for commuters with functional sight limitations and the integration of the systems with other infrastructure and the safety of all commuter. In addition to the issues of functionality, this paper will address the influence of misdirected foreign expertise that set the initial BRT Systems on a high floor vehicle modality, which has created operational challenges that have seriously compromised functional universal access. This presentation will highlight these challenges, opportunities and solutions, the procedural complexities, as well as the inherent resistance

Methods The Rapid Assessment Protocol for Insulin Access draws on the principles of Rapid Assessment Protocols which have been developed and implemented in several different areas. This protocol was adapted through a thorough literature review on diabetes, chronic condition management and medicine supply in developing countries. A visit to three countries in sub-Saharan Africa and meetings with different experts in the field of diabetes helped refine the questionnaires. Following the development of the questionnaires these were tested with various people familiar with diabetes and/or healthcare in developing countries. The Protocol was piloted in Mozambique then refined and had two further iterations in Zambia and Mali. Translations of questionnaires were made into local languages when necessary, with back translation to ensure precision. Results In each country the protocol was implemented in 3 areas – the capital city, a large urban centre and a predominantly rural area and their respective surroundings. Interviews were carried out by local teams trained on how to use the tool. Data was then collected and entered into a database for analysis. Conclusion The Rapid Assessment Protocol for Insulin Access was developed to provide a situational analysis of Type 1 diabetes, in order to make recommendations to the national Ministries of Health and Diabetes Associations. It provided valuable information on patients' access to insulin, syringes, monitoring and care. It was thus able to sketch a picture of the health care system with regards to its ability to

Myanmar’s recent transition from military rule towards a more democratic government has largely ended decades of political and economic isolation. Although Myanmar remains heavily forested, increased development in recent years has been accompanied by exceptionally high rates of forest loss. In this study, we document the rapid progression of deforestation in and around the proposed Lenya National Park, which includes some of the largest remaining areas of lowland evergreen rainforest in mainland Southeast Asia. The globally unique forests in this area are rich in biodiversity and remain a critical stronghold for many threatened and endangered species, including large charismatic fauna such as tiger and Asian elephant. We also conducted a rapid assessment survey of the herpetofauna of the proposed national park, which resulted in the discovery of two new species of bent-toed geckos, genus Cyrtodactylus. We describe these new species, C. lenya sp. nov. and C. payarhtanensis sp. nov., which were found in association with karst (i.e., limestone) rock formations within mature lowland wet evergreen forest. The two species were discovered less than 35 km apart and are each known from only a single locality. Because of the isolated nature of the karst formations in the proposed Lenya National Park, these geckos likely have geographical ranges restricted to the proposed protected area and are threatened by approaching deforestation. Although lowland evergreen rainforest has vanished from most of continental Southeast Asia, Myanmar can still take decisive action to preserve one of the most biodiverse places on Earth.

Anaesthesia machine failure requires rapid solutions to maintain ventilation and anaesthesia. During procedures with poor access to the patient's airway, it may not be possible to use a self-inflating mechanical ventilation device (SIMVD) for emergency ventilation, and alternative solutions are needed. We evaluated five methods for rescue ventilation using a patient simulator. In Method 1, we used the inspiratory and expiratory tubes and the alternative common gas outlet (ACGO) on the anaesthesia machine to produce a Mapleson E system. In Method 2, we used the tubes, ACGO and an open-ended reservoir bag to produce a Mapleson F system, controlling the bag to achieve ventilation. In Method 3, we attached a SIMVD to the inspiratory tube, and controlled occlusion of the expiratory tube. In Method 4, we used the tubes and ACGO in a Mapleson F configuration, replacing the open-ended bag with a SIMVD to facilitate manual ventilation. In Method 5, we attached a SIMVD to the expiratory tube and left the inspiratory tube attached to its mounting. We were able to achieve ventilation, maintain inhalational anaesthesia, and prevent expired gas rebreathing in Methods 1 and 2. In Method 3 ventilation was achieved with minimal rebreathing of expiratory gas, but with no inhalational agent. Methods 4 and 5 led to rebreathing. Our findings indicate that Methods 1 or 2 are the preferred rapid solutions to maintain ventilation and inhalational anaesthesia in the event of anaesthesia machine failure where there is poor airway access.

Full Text Available The use of microwave energy for the synthesis is considered as one of the alternate strategies. The present work includes the synthesis of some newer 2,5-disubstituted-1,3,4-oxadiazole analogues using both conventional and alternate rapid methods.The conventional method involves the synthesis of the target molecules by using cyclodehydrating agent like POCl3, while the other method consists of using some catalytic reagents like PbO2. Also, the short reaction time provided by microwave synthesis makes it ideal for the reaction. Hence, this project describes an efficient and operationally simple method for the microwave-assisted synthesis of some bioactive heterocycles based on NSAIDs.

Full Text Available Here we present a systematic analysis of accessible surface areas and hydrogen bonds of 2554 globular proteins from four structural classes (all-α, all-β, α/β and α+β proteins that is aimed to learn in which structural class the accessible surface area increases with increasing protein molecular mass more rapidly than in other classes, and what structural peculiarities are responsible for this effect. The beta structural class of proteins was found to be the leader, with the following possible explanations of this fact. First, in beta structural proteins, the fraction of residues not included in the regular secondary structure is the largest, and second, the accessible surface area of packaged elements of the beta-structure increases more rapidly with increasing molecular mass in comparison with the alpha-structure. Moreover, in the beta structure, the probability of formation of backbone hydrogen bonds is higher than that in the alpha helix for all residues of α+β proteins (the average probability is 0.73±0.01 for the beta-structure and 0.60±0.01 for the alpha-structure without proline and α/β proteins, except for asparagine, aspartic acid, glycine, threonine, and serine (0.70±0.01 for the beta-structure and 0.60±0.01 for the alpha-structure without the proline residue. There is a linear relationship between the number of hydrogen bonds and the number of amino acid residues in the protein (Number of hydrogen bonds=0.678·number of residues-3.350.

Full Text Available The development of public transit systems that are accessible and safe for everyone, including people with special needs, is an objective that is justified from the civic and economic points of view. Unfortunately, public transit services are conceived for people who do not have reduced physical or cognitive abilities. In this paper, we present an intelligent public transit system by highway with the goal of facilitating access and improving the safety of public transit for persons with special needs. The system is deployed using components that are commonly available in transport infrastructure, e.g., sensors, mobile communications systems, and positioning systems. In addition, the system can operate in non-urban transport contexts, e.g., isolated rural areas, where the availability of basic infrastructure, such as electricity and communications infrastructures, is not always guaranteed. To construct the system, the principles and techniques of Ubiquitous Computing and Ambient Intelligence have been employed. To illustrate the utility of the system, two cases of services rendered by the system are described: the first case involves a surveillance system to guarantee accessibility at bus stops; the second case involves a route assistant for blind people.

The Geodetic Seamless Archive Center (GSAC) project is a NASA ROSES ACCESS funded effort with the goal to define and implement a web service API for uniform querying across multiple geodetic data repositories. The project information technology partners include two International GNSS Service (IGS) Data Centers, CDDIS and SOPAC, and a third global NSF and NASA-funded Data Center, UNAVCO. A science partner, the University of Nevada, Reno Geodetic Laboratory is utilizing the services and contributing new quality assessment products. Each of the participant data centers has its own internal database schema and various web-based access mechanisms to suit the needs of their individual user communities. The software engineering challenge that we faced was to unify these access mechanisms into a common web service API. To facilitate the development of the GSAC interfaces within these disparate repositories we have developed a Java-based open source middleware framework called the GSAC Service Layer (GSL). It was recognized early on in the project that much of the required functionality within each repository could be provided by a common software layer, thus achieving a substantial reduction in the development effort required by each partner institution. The GSL provides a range of common services for repository configuration, initialization, database management, web interface generation, and data model and metadata creation. Each repository implementation then simply focuses on the core task of responding to query requests and delivering to the GSL layer the internal results. The GSL layer is then responsible for encoding the results in the desired format. A fundamental challenge in developing a framework such as the GSL is balancing the trade-off between the agnosticism needed within the GSL so that it is applicable to a wide range of problem domains and the specific needs required for a particular repository implementations. The GSL addresses this challenge through an
This paper describes network-centric operations, where a virtual mission operations center autonomously receives sensor triggers, and schedules space and ground assets using Internet-based technologies and service-oriented architectures. For proof-of-concept purposes, sensor triggers are received from the United States Geological Survey (USGS) to determine targets for space-based sensors. The Surrey Satellite Technology Limited (SSTL) Disaster Monitoring Constellation satellite, the United Kingdom Disaster Monitoring Constellation (UK-DMC), is used as the space-based sensor. The UK-DMC s availability is determined via machine-to-machine communications using SSTL s mission planning system. Access to/from the UK-DMC for tasking and sensor data is via SSTL s and Universal Space Network s (USN) ground assets. The availability and scheduling of USN s assets can also be performed autonomously via machine-to-machine communications. All communication, both on the ground and between ground and space, uses open Internet standards.

The deployment and permanent operation of Space Station Freedom will enable researchers to enter a new era in the 21st century, in which continuous on-orbit experimentation and observation become routine. In support of this objective, the Space Station Freedom Program Office has initiated the Express Payload Project. The fundamental project goal is to reduce the marginal cost associated with small payload development, integration, and operation. This is to be accomplished by developing small payload accommodations hardware and a new streamlined small payload integration process. Standardization of small payload interfaces, certification of small payload containers, and increased payload developer responsibility for mission success are key aspects of the Express Payload Project. As the project progresses, the principles will be applied to both pressurized payloads flown inside the station laboratories and unpressurized payloads attached to the station external structures. The increased access to space afforded by Space Station Freedom and the Express Payload Project has the potential to significantly expand the scope, magnitude, and success of future research in the microgravity environment.

The long lead and cycle times currently associated with development and launch of satellite systems have established a prohibitive environment for responsive deployment of tactical capability to orbit. With the advent of the RASCAL program - poised to offer launch capability to Low Earth Orbit (LEO) within 24 hours - there is a clear motivation for a comparable, multi-mission, rapidly configurable microsatellite. The SCOUT program is developing the key enabling technologies that will enable this capability while also addressing the production and logistic challenges essential to its implementation. Intrinsic to the design will be a "Plug-and-Sense" capability, which will enable a vehicle to detect the presence and orientation of integrated subsystem modules, as well as ascertain their function, and communicate key performance parameters. The system will utilize a heuristic, self-interrogation approach to provide a robust means of performing configuration and diagnostics activities that transcend nominal housekeeping routines to include an enhanced degree of system autonomy. A minimally structured design, emphasizing a lightweight, interchangeable framework will enable quick integration and deployment, while preserving high on-orbit payload mass fraction. Similarly, the system will also feature a novel approach to assembly, integration, and test activities that spans ground through on-orbit operations.

Full Text Available OBJETIVO: O artigo visa rever os passos da obtenção de uma via aérea segura no atendimento da criança criticamente enferma. FONTES DOS DADOS: Revisão de artigos a partir da busca na base de dados Medline até abril de 2003, utilizando os unitermos intubação, crianças e sedação. SÍNTESE DOS DADOS: O comprometimento da via aérea é incomum, porém quando ocorre, depende de profissionais treinados para a rápida obtenção da via aérea, de maneira segura, precoce e sem causar prejuízos para tais pacientes. O método preconizado para tal abordagem é a seqüência rápida de intubação que além de preparação, utiliza sedação e bloqueador neuromuscular. Observamos que não é possível a aplicação de um protocolo único de intubação, pois depende da indicação e condições do paciente. Definimos doses das medicações mais utilizadas em nosso meio, pois acreditamos que pouco se conhece do real efeito de drogas sedativas e analgésicas. Na maioria das situações, a associação de um analgésico opióide (fentanil na dose de 5 a 10 µg/kg e um sedativo (midazolam 0,5 mg/kg e um bloqueador neuromuscular são suficientes para a intubação traqueal. CONCLUSÕES: Treinamento, conhecimento, habilidade na obtenção da via aérea são fundamentais para o intensivista pediátrico e são vitais para o adequado atendimento de crianças gravemente enfermas. Apresentamos um texto objetivo e dinâmico, visando a oferecer subsídios para a geração de protocolos a serem implementados de acordo com facilidades e dificuldades de cada serviço.OBJECTIVE: To review the steps involved in safe airway management in critically ill children.

The goal of the study was to assess semantic priming to emotion and nonemotion cue words using a novel measure of associational breadth for participants who either took rapid eye movement (REM) or nonrapid eye movement (NREM) naps or who remained awake; assess relation of priming to REM sleep consolidation and REM sleep inertia effects. The associational breadth task was applied in both a priming condition, where cue-words were signaled to be memorized prior to sleep (primed), and a nonpriming condition, where cue words were not memorized (nonprimed). Cue words were either emotional (positive, negative) or nonemotional. Participants were randomly assigned to either an awake (WAKE) or a sleep condition, which was subsequently split into NREM or REM groups depending on stage at awakening. Hospital-based sleep laboratory. Fifty-eight healthy participants (22 male) ages 18 to 35 y (Mage = 23.3 ± 4.08 y). The REM group scored higher than the NREM or WAKE groups on primed, but not nonprimed emotional cue words; the effect was stronger for positive than for negative cue words. However, REM time and percent correlated negatively with degree of emotional priming. Priming occurred for REM awakenings but not for NREM awakenings, even when the latter sleep episodes contained some REM sleep. Associational breadth may be selectively consolidated during REM sleep for stimuli that have been tagged as important for future memory retrieval. That priming decreased with REM time and was higher only for REM sleep awakenings is consistent with two explanatory REM sleep processes: REM sleep consolidation serving emotional downregulation and REM sleep inertia. © 2015 Associated Professional Sleep Societies, LLC.

Polyether ionophores are a unique class of polyketides with broad-spectrum activity and outstanding potency for the control of drug-resistant bacteria and parasites, and they are produced exclusively by actinomycetes. A special epoxidase gene encoding a critical tailoring enzyme involved in the biosynthesis of these compounds has been found in all five of the complete gene clusters of polyether ionophores published so far. To detect potential producer strains of these antibiotics, a pair of degenerate primers was designed according to the conserved regions of the five known polyether epoxidases. A total of 44 putative polyether epoxidase gene-positive strains were obtained by the PCR-based screening of 1,068 actinomycetes isolated from eight different habitats and 236 reference strains encompassing eight major families of Actinomycetales. The isolates spanned a wide taxonomic diversity based on 16S rRNA gene analysis, and actinomycetes isolated from acidic soils seemed to be a promising source of polyether ionophores. Four genera were detected to contain putative polyether epoxidases, including Micromonospora, which has not previously been reported to produce polyether ionophores. The designed primers also detected putative epoxidase genes from diverse known producer strains that produce polyether ionophores unrelated to the five published gene clusters. Moreover, phylogenetic and chemical analyses showed a strong correlation between the sequence of polyether epoxidases and the structure of encoded polyethers. Thirteen positive isolates were proven to be polyether ionophore producers as expected, and two new analogues were found. These results demonstrate the feasibility of using this epoxidase gene screening strategy to aid the rapid identification of known products and the discovery of unknown polyethers in actinomycetes.

We present a practical trifluoromethyl-directed Wacker-type oxidation of internal alkenes that enables rapid access to β-trifluoromethyl-substituted ketones. Allylic trifluoromethyl-substituted alkenes bearing a wide range of functional groups can be oxidized in high yield and regioselectivity. The distance dependence of the regioselectivity was established by systematic variation of the number of methylene units between the double bond and the trifluoromethyl group. The regioselectivity enforced by traditional directing groups could even be reversed by introduction of a competing trifluoromethyl group. Besides being a new powerful synthetic method to prepare fluorinated molecules, this work directly probes the role of inductive effects on nucleopalladation events. © 2014 WILEY-VCH Verlag GmbH & Co.

Surface properties have been obtained on several classes of thermal protection systems (TPS) using data from both side-arm-reactor and arc-jet facilities. Thermochemical stability, optical properties, and coefficients for atom recombination were determined for candidate TPS proposed for single-stage-to-orbit vehicles. The systems included rigid fibrous insulations, blankets, reinforced carbon carbon, and metals. Test techniques, theories used to define arc-jet and side-arm-reactor flow, and material surface properties are described. Total hemispherical emittance and atom recombination coefficients for each candidate TPS are summarized in the form of polynomial and Arrhenius expressions.

Most interventions designed to reduce teen pregnancy rates have not focused on pregnant and/or parenting adolescents. Therefore, a large randomized controlled trial was conducted regarding a motivational interviewing program entitled Teen Options to Prevent Pregnancy in a low-income sample of adolescent mothers. This program recommended monthly sessions between a participant and a registered nurse over 18 months. This program also featured facilitated birth control access through transportation assistance and a part-time contraceptive clinic. The impact of this program on rapid repeat pregnancies at 18 months after enrollment was evaluated. Five hundred ninety-eight adolescent females were enrolled from 7 obstetrics-gynecology clinics and 5 postpartum units of a large hospital system in a Midwestern city. Each participant was enrolled at least 28 weeks pregnant or less than 9 weeks postpartum. Each participant was randomized to either the Teen Options to Prevent Pregnancy intervention or a usual-care control condition. Intervention participants averaged 4.5 hours of assistance. Participants were contacted by blinded research staff at 6 and 18 months to complete self-report surveys. Differences in outcomes between the intervention and control groups were assessed using ordinary least-squares regression. There was an 18.1% absolute reduction in self-reported repeat pregnancy in the intervention group relative to the control group (20.5% vs 38.6%%; P Pregnancy program represents one of the few evidence-based interventions to reduce rapid repeat teen pregnancy. This relatively brief intervention may be a viable alternative to more time-intensive programs that adolescent mothers may be unable or unwilling to receive. Copyright © 2017 Elsevier Inc.

Full Text Available The process of radiationless energy transfer from a chromophore in an excited electronic state (the “donor” to another chromophore (an “acceptor”, in which the energy released by the donor effects an electronic transition, is known as “Förster Resonance Energy Transfer” (FRET. The rate of energy transfer is dependent on the sixth power of the distance between donor and acceptor. Determining FRET efficiencies is tantamount to measuring distances between molecules. A new method is proposed for determining FRET efficiencies rapidly, quantitatively, and non-destructively on ensembles containing donor acceptor pairs: at wavelengths suitable for mutually exclusive excitations of donors and acceptors, two laser beams are intensity-modulated in rectangular patterns at duty cycle ½ and frequencies ƒ1 and ƒ2 by electro-optic modulators. In an ensemble exposed to these laser beams, the donor excitation is modulated at ƒ1, and the acceptor excitation, and therefore the degree of saturation of the excited electronic state of the acceptors, is modulated at ƒ2. Since the ensemble contains donor acceptor pairs engaged in FRET, the released donor fluorescence is modulated not only at ƒ1 but also at the beat frequency Δƒ: = |ƒ1 − ƒ2|. The depth of the latter modulation, detectable via a lock-in amplifier, quantitatively indicates the FRET efficiency.

The 1983 Orphan Drug Act created incentives for the development of orphan drugs. Despite its successes, including a substantial increase in new drugs, approved orphan drugs still treat fewer than 5 percent of registered rare diseases. In addition, concerns have arisen about the high prices of many of these therapies, which can cost hundreds of thousands of dollars per patient each year. In this article, we propose a new "grant-and-access pathway," in which drug developers could opt to compete for federal grants to subsidize the costs of clinical testing. In return for the grant funding, companies would no longer claim orphan drug tax credits and would agree to price caps for marketed products based on the duration and costs associated with drug development, expected market size, and target rate of return. We identify scenarios in which such a policy could provide a net benefit to society.
This pattern conforms to that describing the introduction of new technologies in other settings. Continued use in practice and the concordance of usage between practices confirms that rapid and reliable access to laboratory reports from primary care is both useful and used.
The \\'accuracy\\' of age, blood pressure, clinical features, duration and diabetes (ABCD(2)) scoring by non-stroke specialists referring patients to a daily Rapid Access Stroke Prevention (RASP) service is unclear, as is the accuracy of ABCD(2) scoring by trainee residents. In this prospective study, referrals were classified as \\'confirmed TIAs\\' if the stroke specialist confirmed a clinical diagnosis of possible, probable or definite TIA, and \\'non-TIAs\\' if patients had a TIA mimic or completed stroke. ABCD(2) scores from referring physicians were compared with scores by experienced stroke specialists and neurology\\/geriatric medicine residents at a daily RASP clinic; inter-observer agreement was examined. Data from 101 referrals were analysed (mean age=60.0years, 58% male). The median interval between referral and clinic assessment was 1day. Of 101 referrals, 52 (52%) were \\'non-TIAs\\': 45 (86%) of 52 were \\'TIA mimics\\' and 7 (14%) of 52 were completed strokes. There was only \\'fair\\' agreement in total ABCD(2) scoring between referring physicians and stroke specialists (κ=0.37). Agreement was \\'excellent\\' between residents and stroke specialists (κ=0.91). Twenty of 29 patients scored as \\'moderate to high risk\\' (score 4-6) by stroke specialists were scored \\'low risk\\' (score 0-3) by referring physicians. ABCD(2) scoring by referring doctors is frequently inaccurate, with a tendency to underestimate stroke risk. These findings emphasise the importance of urgent specialist assessment of suspected TIA patients, and that ABCD(2) scores by non-stroke specialists cannot be relied upon in isolation to risk-stratify patients. Inter-observer agreement in ABCD(2) scoring was \\'excellent\\' between residents and stroke specialists, indicating short-term training may improve accuracy.

We report two cases of ileoanal J-pouch rupture after rapid consumption of high-fiber, high-calorie meals. We review the food intake, presentation, laboratory and radiographic data, and course of two patients who developed ileoanal J-pouch perforation after rapid consumption of meals rich in fiber or calories or both. The potential association between food consumption and rupture is explored. The authors propose that the rapid ingestion of a high-fiber, high-calorie meal may lead to an acute intraluminal pressure elevation or a closed-loop obstruction. These effects may be the basis for an association between food ingestion patterns and perforation at the distal transection site in an ileoanal J-pouch. The authors hypothesize that the rapid ingestion of a high-fiber, high-calorie meal may be associated with J-pouch perforation. Further investigative efforts are needed to confirm this association and to evaluate whether a causal relationship is present. If causality is established, physicians may develop a higher index of suspicion for pouch rupture in patients who present with abdominal disturbances after the rapid ingestion of a high-fiber, high-calorie meal.

Hemostasis at the femoral venous access site after atrial fibrillation (AF) ablation is often prolonged because of aggressive anticoagulation and the use of several large-sized sheaths. A newly developed hemostatic pad containing a natural mineral called kaolin causes blood to clot quickly. We evaluated the efficacy of this pad for hemostasis at the venous access site after AF ablation. Patients who were scheduled to undergo AF ablation were randomized to be treated with manual compression with (n = 59) or without kaolin-impregnated pads (n = 59) as hemostatic approaches at the femoral venous access site following sheath removal. Hemostasis time, rebleeding frequency, massive hematoma, device-related complications, and deep venous thrombosis (DVT) were compared between the two groups. Hemostasis time in the patients treated with kaolin-impregnated pads was significantly shorter than in those treated without (6.1 ± 2.3 vs. 14.5 ± 4.0 min; p pads was the only independent variable reducing hemostasis time (β = -0.78; p pads; p = 0.35). Only one patient had a massive groin hematoma, and no patient had device-related complications or DVT. Kaolin-impregnated hemostatic pads safely and effectively decreased hemostasis time for the femoral venous access site in patients undergoing AF ablation. However, whether its use allows earlier postprocedural ambulation is difficult to predict.

Full Text Available Objective. In 2009, 4 749 rapid HIV tests were run in Morelos, Mexico, despite lacking evidence on their results. This article seeks to analyze how public health organization relates to utility of rapid HIV test among healthcare users. Materials and methods. Joint study: comparison of differences in applied test and positive results for each group with the Bonferroni statistical tool, observational study in 34 health subsystems, and 11 interviews with public healthcare users. Results. Each subsystem processes influenced the use and usefulness of screening; for instance, primary care centers test only pregnant women and exclude men who have sex with men (MSM. That group shows significant differences (p<0.007 in the HIV-positive test with respect to other groups. Conclusions. Despite the availability of rapid detection tests and epidemiological evidence, the way public health services are organized impedes an efficient diagnosis in the group with higher risk, namely MSM. The distribution of rapid HIV tests was guided by stigmatization.

The EU has assumed ambitious targets and strategies for the promotion of renewable sources of energy (RES) binding to all its member states. This report sets out to examine the proposed EU-wide policy instrument designed to help achieve the targets on renewable electricity and heat - the trading of Guarantees of Origin (GO). It analyses the fate of the GO trading proposal in the European policy-making machinery during 2007 and 2008. It first discusses its origins, key components and points of contention, and then examines key factors behind the policy development leading first to its development and subsequently to its abandonment in 2008. Addressing these factors, the report explores first the near-term policy-making process before and after the proposal on GO trading was tabled in January 2008, focusing on processes in the European bureaucracy and how they were influenced by different interest groups and member state governments. It then takes a step back and looks at how competing policy frames over time have shaped the GO instrument debate. Results show how a strong internal market frame acted as a primary driving force in the Commission throughout the 2000s to promote the GO trading instrument. The subsequent collapse of the GO trading proposal can be largely attributed to a) the lack of a strong lobby in favour of GO, b) the accumulated experience with and institutionalisation of national RES support policy, and c) growing general political concerns for supply security, innovation and competitiveness. In the end, the fall of the GO trading instrument is indicative of how the underlying political battle line between advocates of the European internal market and guardians of national interests has moved in favour of the latter in recent years.

In Thailand and the US negotiating FTA, the 'TRIPs-Plus' is one of the US proposal which would result in an extension of market exclusivity of innovative drugs. In addition, it would foreseeably lead to high and unaffordable medicine prices and inaccessibility to essential medicines. To quantify the impact on medicine expense and medicine accessibility. Based on 2000 to 2003 Thai Food and Drug Administration (FDA)'s and the Drug & Medical Supply Information Center (DMSIC), costs and accessibility were estimated upon the price and quantity costing between innovative drugs and their generics plus some parameters found from their competitive behaviour. Thereafter, we simulated the 10-year potential additional expense on the 2003 unit price of the patented and monopolized non-patented medicines. In 2003, the availability of generics helped to save 104.5% of actual expense and the accessibility would increase by 53.6%. By extension of market exclusivity, given that there were 60 new items approved annually, the cumulative potential expense was projected to be $US 6.2 million for the first year to $US 5215.8 million in tenth year. The TRIPs-Plus proposal would result in a significant increase in the medicine expense; and a delay in the increase in drug accessibility via generics. Several options as well as other related mechanisms to help reduce the negative impact are proposed.

Full Text Available Las investigaciones sobre accesibilidad a medicamentos con encuestas a hogares, son de gran importancia para verificar la realidad y eficacia de las medidas de intervención para mejorar el acceso de medicamentos en la población. Desafortunadamente dichos estudios, además de ser escasos, presentan problemas metodológicos, que en su mayor parte son consecuencia de una ausencia de uniformidad en las definiciones operacionales de acceso y su diferenciación con las dimensiones de la accesibilidad. El objetivo de la propuesta es diferenciar ambos términos. Se propone definir operacionalmente acceso a medicamentos al proceso de verificación de la obtención de un fármaco por un paciente, independiente de diversos factores que pueden afectar el proceso. Se introduce el término "Usabilidad de fármacos", definiéndolo operacionalmente como los procesos destinados a medir las dimensiones de la accesibilidad de los medicamentos: disponibilidad física, asequibilidad, accesibilidad geográfica, aceptabilidad (o satisfacción.Research about accessibility to medicines through household surveys is very important in order to verify the reality and effectiveness of interventions done to increase the access of the population to the medications. Unfortunately, such studies, on top of being very few, have methodological problems, which mostly result from a lack of uniformity in the operational definitions of access and the differentiation with the dimensions of accessibility. The aim of this paper is to propose setting a difference between both terms. We propose an operational definition of access to medications as the process of verification of the purchase of a drug by a patient, independently from many factors that can affect this process. The term "usability of drugs" is introduced, defining it operationally as aimed at measuring the dimensions of the accessibility to the medications: physical availability, affordability, geographical accessibility

A method of inhibiting the expression of particular genes by using external guide sequences (EGSs) has been improved in its rapidity and specificity. Random EGSs that have 14-nt random sequences are used in the selection procedure for an EGS that attacks the mRNA for a gene in a particular location. A mixture of the random EGSs, the particular target RNA, and RNase P is used in the diagnostic procedure, which, after completion, is analyzed in a gel with suitable control lanes. Within a few hours, the procedure is complete. The action of EGSs designed by an older method is compared with EGSs designed by the random EGS method on mRNAs from two bacterial pathogens.
Full Text Available BACKGROUND: The wheat stripe rust fungus (Puccinia striiformis f. sp. tritici, PST is responsible for significant yield losses in wheat production worldwide. In spite of its economic importance, the PST genomic sequence is not currently available. Fortunately Next Generation Sequencing (NGS has radically improved sequencing speed and efficiency with a great reduction in costs compared to traditional sequencing technologies. We used Illumina sequencing to rapidly access the genomic sequence of the highly virulent PST race 130 (PST-130. METHODOLOGY/PRINCIPAL FINDINGS: We obtained nearly 80 million high quality paired-end reads (>50x coverage that were assembled into 29,178 contigs (64.8 Mb, which provide an estimated coverage of at least 88% of the PST genes and are available through GenBank. Extensive micro-synteny with the Puccinia graminis f. sp. tritici (PGTG genome and high sequence similarity with annotated PGTG genes support the quality of the PST-130 contigs. We characterized the transposable elements present in the PST-130 contigs and using an ab initio gene prediction program we identified and tentatively annotated 22,815 putative coding sequences. We provide examples on the use of comparative approaches to improve gene annotation for both PST and PGTG and to identify candidate effectors. Finally, the assembled contigs provided an inventory of PST repetitive elements, which were annotated and deposited in Repbase. CONCLUSIONS/SIGNIFICANCE: The assembly of the PST-130 genome and the predicted proteins provide useful resources to rapidly identify and clone PST genes and their regulatory regions. Although the automatic gene prediction has limitations, we show that a comparative genomics approach using multiple rust species can greatly improve the quality of gene annotation in these species. The PST-130 sequence will also be useful for comparative studies within PST as more races are sequenced. This study illustrates the power of NGS for

It has been demonstrated that insulin-mediated recruitment of microvascular blood volume is associated with insulin sensitivity. We hypothesize that insulin rapidly stimulates penetration of red blood cells (RBC) and plasma into the glycocalyx and thereby promotes insulin-mediated glucose uptake by increasing intracapillary blood volume. Experiments were performed in rats; the role of the glycocalyx was assessed by enzymatic degradation using a bolus of hyaluronidase. First, the effect of insulin on glycocalyx accessibility was assessed by measuring the depth of penetration of RBCs into the glycocalyx in microvessels of the gastrocnemius muscle with Sidestream Dark-field imaging. Secondly, peripheral insulin sensitivity was determined using intravenous insulin tolerance tests (IVITT). In addition, in a smaller set of experiments, intravital microscopy of capillary hemodynamics in cremaster muscle and histological analysis of the distribution of fluorescently labeled 40 kDa dextrans (D40) in hindlimb muscle was used to evaluate insulin-mediated increases in capillary blood volume. Insulin increased glycocalyx penetration of RBCs by 0.34±0.44 µm (Pglucose disposal compared to control rats. Insulin-mediated increases in capillary blood volume were reflected by a rapid increase in capillary tube hematocrit from 21.1±10.1% to 29.0±9.8% (Pblood in muscle, and this is associated with an increased blood volume in individual capillaries. Hyaluronidase treatment of the glycocalyx abolishes the effects of insulin on capillary blood volume and impairs insulin-mediated glucose disposal.

Chest pain is common and places a significant burden on hospital resources. Many patients with undifferentiated low- to intermediate-risk chest pain are admitted to hospital. Rapid-access cardiology (RAC) services are hospital co-located, cardiologist-led outpatient clinics that provide rapid assessment and immediate management but not long-term management. This service model is described as part of chest pain management and the National Service Framework for coronary heart disease in the United Kingdom (UK). We review the evidence on the effectiveness, safety and acceptability of RAC services. Our review finds that early assessment in RAC outpatient services of patients with suspected angina, without high-risk features suspicious of an acute coronary syndrome, is safe, can reduce hospitalisations, is cost effective and has good medical practitioner and patient acceptability. However, the literature is limited in that the evaluation of this model of care has been only in the UK. It is potentially suited to other settings and needs further evaluation in other settings to assess its utility. © 2016 Royal Australasian College of Physicians.

Studies that investigate people's perceptions of the phenology of certain species still area few; yet this approach is important for effective decision-making for conservation. The aim of this study was to investigate the phenology of Spondias tuberosa Arruda (Anacardiaceae, a native species of economic and ecological importance in northeastern Brazil, in five landscape units (LUs (Mountain, Mountain Base, Pasture, Cultivated Areas and Homegardens of a Caatinga region in Altinho, Pernambuco, northeastern Brazil. These data could then be compared with local people's perceptions of the species’ phenophases. Method Collection of phenological data was carried out monthly from February 2007 to January 2009 and included activity, intensity and synchronization of reproductive and vegetative phenophases. Ethnobotanical data were gathered using a collaborative approach to access local people’s knowledge about the species’ phenological schedule. Results There were no significant differences in the intensity of phenophases among LUs, and there was a correspondence between people’s perception of phenophases and the phenological data collected. The data show that the different management practices for LUs did not influence the phenology of the species. Conclusion The main conclusion of this study is the use of traditional knowledge as interesting tool for rapid phenological diagnosis. However further studies need to be developed to test this tool in other environments and cultural contexts.

International recognition that people with disabilities were excluded from the Millennium Development Goals has led to better inclusion of people with disabilities in the recently agreed Global Goals for Sustainable Development (SDGs) 2015-2030. Given the current global agenda for disability inclusion, it is crucial to increase the understanding of the situation of people with disabilities in the Philippines. The aim of this study was to estimate the prevalence of disability and compare the well-being and access to the community between people with and without disabilities. A population-based survey was undertaken in District 2 of Quezon City and in Ligao City. 60 clusters of 50 people aged 18 years and older were selected with probability proportion to size sampling from both locations. The Rapid Assessment of Disability (RAD) survey was used to identify people with disabilities based on their responses to activity limitations. The levels of well-being and access to the community for people with disabilities were compared with controls matched by age, gender, and cluster. Information on barriers to accessing the community was also collected. The prevalence of disability was 6.8 (95 % CI: 5.9, 7.9) and 13.6 % (95 % CI: 11.4, 16.2) in Quezon City and Ligao City respectively. Psychological distress was the most commonly reported condition in both locations, although it was often reported with a co-morbid condition related to sensory, physical, cognitive, and communication difficulties. The prevalence of disability was associated with age and no schooling, but not associated with poverty. People with disabilities had significantly lower well-being scores and reduced access to health services, work, rehabilitation, education, government social welfare, and disaster management than people without disability. Having a disability and negative family attitudes were reported as barriers for people with disabilities participating in work, community meetings, religious

As part of the Subglacial Access and Fast Ice Research Experiment (SAFIRE) pressurised hot water was used to drill four 603-616 m-long boreholes to the bed of the Greenland Ice Sheet at a site located 30 km from the calving front of fast-flowing, marine-terminating Store Glacier (70 degrees N, ~1000 m elevation). Four wired sensor strings were successfully installed in three of the boreholes. These included a thermistor string to obtain the englacial temperature profile installed in the same borehole as a string of tilt sensors to measure borehole deformation, and two sets of combined water pressure, electrical conductivity and turbidity sensors installed just above the bed in separate, adjacent boreholes. The boreholes made a strong hydrological connection to the bed during drilling, draining rapidly to ~80 m below the ice surface. The connection of subsequent boreholes was observed as a perturbation in water pressure and temperature recorded in neighbouring boreholes, indicating an effective hydrological connection between them. The sensors, which were wired to data-loggers at the surface, operated for between ~30 and >80 days from late summer into autumn before the cables stretched and snapped, with the lowermost sensors failing first. The records obtained from these sensors reveal (i) subglacial water pressures that were close to overburden but which generally increased through the period of measurement and varied diurnally by ~0.3 m, (ii) a minimum englacial temperature of -21 degrees C underlain by a zone of temperate ice, some tens of m thick, located immediately above the bed, and (iii) high rates of internal deformation and strain that increased towards the bed. These borehole observations are complemented by GPS measurements of ice motion, meteorological data, and seismic and radar surveys.

Copyright and licensing of scientific data, internationally, are complex and present legal barriers to data sharing, integration and reuse, and therefore restrict the most efficient transfer and discovery of scientific knowledge. Much data are included within scientific journal articles, their published tables, additional files (supplementary material) and reference lists. However, these data are usually published under licenses which are not appropriate for data. Creative Commons CC0 is an appropriate and increasingly accepted method for dedicating data to the public domain, to enable data reuse with the minimum of restrictions. BioMed Central is committed to working towards implementation of open data-compliant licensing in its publications. Here we detail a protocol for implementing a combined Creative Commons Attribution license (for copyrightable material) and Creative Commons CC0 waiver (for data) agreement for content published in peer-reviewed open access journals. We explain the differences between legal requirements for attribution in copyright, and cultural requirements in scholarship for giving individuals credit for their work through citation. We argue that publishing data in scientific journals under CC0 will have numerous benefits for individuals and society, and yet will have minimal implications for authors and minimal impact on current publishing and research workflows. We provide practical examples and definitions of data types, such as XML and tabular data, and specific secondary use cases for published data, including text mining, reproducible research, and open bibliography. We believe this proposed change to the current copyright and licensing structure in science publishing will help clarify what users - people and machines - of the published literature can do, legally, with journal articles and make research using the published literature more efficient. We further believe this model could be adopted across multiple publishers, and invite

The impressive progress recently observed in adult cancers through the introduction of new drugs has not yet been translated to adolescents between 12 and 17 years of age. Currently adolescents are grouped with children, so their access to new, effective drugs already available for adults is delayed because paediatric drug development starts late relative to adult programmes. Moreover, specific early phase trials designed exclusively for adolescents in rare diseases recruit poorly, even if conducted internationally. Evidence has shown that adolescents demonstrate similar toxicity profiles, maximum tolerated doses and pharmacokinetic parameters to adults. Although they may have specific vulnerabilities and their interests should be protected, they are, in many countries in Europe, entitled to provide informed consent themselves. There are no insurmountable scientific, medical, or regulatory barriers to their participation in Phase-I to III adult trials. Based on a review of the literature, the multi-stakeholder platform ACCELERATE, with representatives from academia, patient/parent advocacy groups, regulatory agencies and pharmaceutical companies, proposes the inclusion of adolescents in adult Phase-I to III trials of cancer drugs targeting a relevant disease or mechanism of action, without requiring preceding specific paediatric trials. The trials, however, should be delivered in age-appropriate clinical care settings by clinicians with adolescent trial expertise. Joint adolescent-adult trials will not exclude adolescents from participating in paediatric trials, as these approaches are complementary. This strategy is considered to be safe, rational, efficient and would provide more clinical trial options and accelerate drug development for adolescents with cancer. © The Author 2018.

Long-term data collection is a challenging task in the domain of medical research. Many effects in medicine require long periods of time to become traceable e.g. the development of secondary malignancies based on a given radiotherapeutic treatment of the primary disease. Nevertheless, long-term studies often suffer from an initial lack of available information, thus disallowing a standardized approach for their approval by the ethics committee. This is due to several factors, such as the lack of existing case report forms or an explorative research approach in which data elements may change over time. In connection with current medical research and the ongoing digitalization in medicine, Long Term Medical Data Registries (MDR-LT) have become an important means of collecting and analyzing study data. As with any clinical study, ethical aspects must be taken into account when setting up such registries. This work addresses the problem of creating a valid, high-quality ethics committee proposal for medical registries by suggesting groups of tasks (building blocks), information sources and appropriate methods for collecting and analyzing the information, as well as a process model to compile an ethics committee proposal (EsPRit). To derive the building blocks and associated methods software and requirements engineering approaches were utilized. Furthermore, a process-oriented approach was chosen, as information required in the creating process of ethics committee proposals remain unknown in the beginning of planning an MDR-LT. Here, we derived the needed steps from medical product certification. This was done as the medical product certification itself also communicates a process-oriented approach rather than merely focusing on content. A proposal was created for validation and inspection of applicability by using the proposed building blocks. The proposed best practice was tested and refined within SEMPER (Secondary Malignoma - Prospective Evaluation of the

A number of governmental agencies have called for enhancing citizens' resilience as a means of preparing populations in advance of disasters, and as a counterbalance to social and individual vulnerabilities. This increasing scholarly, policy, and programmatic interest in promoting individual and communal resilience presents a challenge to the research and practice communities: to develop a translational framework that can accommodate multidisciplinary scientific perspectives into a single, applied model. The Resilience Activation Framework provides a basis for testing how access to social resources, such as formal and informal social support and help, promotes positive adaptation or reduced psychopathology among individuals and communities exposed to the acute collective stressors associated with disasters, whether human-made, natural, or technological in origin. Articulating the mechanisms by which access to social resources activate and sustain resilience capacities for optimal mental health outcomes post-disaster can lead to the development of effective preventive and early intervention programs.

Full Text Available For nearly 100 years serotyping has been the gold standard for the identification of Salmonella serovars. Despite the increasing adoption of DNA-based subtyping approaches, serotype information remains a cornerstone in food safety and public health activities aimed at reducing the burden of salmonellosis. At the same time, recent advances in whole-genome sequencing (WGS promise to revolutionize our ability to perform advanced pathogen characterization in support of improved source attribution and outbreak analysis. We present the Salmonella In Silico Typing Resource (SISTR, a bioinformatics platform for rapidly performing simultaneous in silico analyses for several leading subtyping methods on draft Salmonella genome assemblies. In addition to performing serovar prediction by genoserotyping, this resource integrates sequence-based typing analyses for: Multi-Locus Sequence Typing (MLST, ribosomal MLST (rMLST, and core genome MLST (cgMLST. We show how phylogenetic context from cgMLST analysis can supplement the genoserotyping analysis and increase the accuracy of in silico serovar prediction to over 94.6% on a dataset comprised of 4,188 finished genomes and WGS draft assemblies. In addition to allowing analysis of user-uploaded whole-genome assemblies, the SISTR platform incorporates a database comprising over 4,000 publicly available genomes, allowing users to place their isolates in a broader phylogenetic and epidemiological context. The resource incorporates several metadata driven visualizations to examine the phylogenetic, geospatial and temporal distribution of genome-sequenced isolates. As sequencing of Salmonella isolates at public health laboratories around the world becomes increasingly common, rapid in silico analysis of minimally processed draft genome assemblies provides a powerful approach for molecular epidemiology in support of public health investigations. Moreover, this type of integrated analysis using multiple sequence

Susceptibility of methionine to oxidation is an important concern for chemical stability during the development of a monoclonal antibody (mAb) therapeutic. To minimize downstream risks, leading candidates are usually screened under forced oxidation conditions to identify oxidation-labile molecules. Here we report results of forced oxidation on a large set of in-house expressed and purified mAbs with variable region sequences corresponding to 121 clinical stage mAbs. These mAb samples were treated with 0.1% H2O2 for 24 hours before enzymatic cleavage below the hinge, followed by reduction of inter-chain disulfide bonds for the detection of the light chain, Fab portion of heavy chain (Fd) and Fc by liquid chromatography-mass spectrometry. This high-throughput, middle-down approach allows detection of oxidation site(s) at the resolution of 3 distinct segments. The experimental oxidation data correlates well with theoretical predictions based on the solvent-accessible surface area of the methionine side-chains within these segments. These results validate the use of upstream computational modeling to predict mAb oxidation susceptibility at the sequence level.

Block copolymer (BCP) derived periodic nanostructures with domain sizes larger than 150 nm present a versatile platform for the fabrication of photonic materials. So far, the access to such materials has been limited to highly synthetically involved protocols. Herein, we report a simple, “user-friendly” method for the preparation of ultrahigh molecular weight linear poly(solketal methacrylate-b-styrene) block copolymers by a combination of Cu-wire-mediated ATRP and RAFT polymerizations. The synthesized copolymers with molecular weights up to 1.6 million g/mol and moderate dispersities readily assemble into highly ordered cylindrical or lamella microstructures with domain sizes as large as 292 nm, as determined by ultra-small-angle x-ray scattering and scanning electron microscopy analyses. Solvent cast films of the synthesized block copolymers exhibit stop bands in the visible spectrum correlated to their domain spacings. The described method opens new avenues for facilitated fabrication and the advancement of fundamental understanding of BCP-derived photonic nanomaterials for a variety of applications.

Driven by the rapid escalation of the wireless capacity requirements imposed by advanced multimedia applications (e.g., ultrahigh-definition video, virtual reality, etc.), as well as the dramatically increasing demand for user access required for the Internet of Things (IoT), the fifth-generation (5G) networks face challenges in terms of supporting large-scale heterogeneous data traffic. Nonorthogonal multiple access (NOMA), which has been recently proposed for the third-generation partnershi...
You will find stuff about workspace, application, page, and so on in every APEX book. But this book is unique because the information it contains is not available anywhere else! Unlike other books, it adopts a stimulating approach to reveal almost every feature necessary for the beginners of Oracle APEX and also takes them beyond the basics. As a technology enthusiast I write on a variety of new technologies, but writing books on Oracle Application Express is my passion. The blood pumping comments I get from my readers on Amazon (and in my inbox) are the main forces that motivate me to write a book whenever a new version of Oracle APEX is launched. This is my fifth book on Oracle APEX (and the best so far) written after discovering the latest 5.1 version. As usual, I’m sharing my personal learning experience through this book to expose this unique rapid web application development platform. In Oracle Application Express you can build robust web applications. The new version is launched with some more prol...

Progress addressing access to oral health is difficult to evaluate because it is unclear what access means. Ozar's proposal that access should be defined by dentists as true dental need is criticized. It is proposed that four different types of treatment are currently identifiable in dentistry: 1) traditional oral health care, 2) oral care that has minimal or no health component, 3) episodic care, and 4) oral health outcomes not resulting from dentist interventions such as fluoridation. Each of these models has a different definition of care and of access. The profession is becoming segmented--including growing disparities among dentists in earning potential--to the point where a single model may no longer be able to cover all needs for oral health.

Full Text Available A practical, rapid and inexpensive method for muscle glucose determination is proposed. The method is based on acid digestion of the sample, followed by neutralization of the solution and the subsequent glucose determination using a domestic glucometer for human blood glucose level control. In a pre-experimental phase, the accuracy of this methodology and the titration method was determined, comparing results to pre-established glucose concentrations. There were significant differences between the glucose reading given by the glucometer and the pre-established glucose concentrations and the results given by the titration method. Nevertheless, when discrepancies (bias were identified, differences resulted non-significant (P = 0.85. Subsequently, muscle glucose concentration (n = 24 was validated in the experimental phase and significant differences were shown between glucose concentration values given by the glucometer and the titration method, the latter considered as a standard method or as a reference (P Se propuso un método práctico, rápido y de bajo costo para determinar glucosa en músculo, basado en una digestión ácida de la muestra de músculo, seguida por una neutralización de la solución y posterior determinación de glucosa, utilizando un glucómetro doméstico para el control de la glicemia sanguínea.

Access is defined as the degree of fit between the user and the service; the better the fit, the better the access. Using the theory developed by Penchansky and Thomas, access is optimized by accounting for the different dimensions of access: accessibility; availability; acceptability; affordability; and adequacy in service design, implementation and evaluation. These dimensions are independent yet interconnected and each is important to assess the achievement of access. However, I argue that one dimension is missing - awareness. I propose that awareness is integral to access, that it should become a permanent part of the theory, and be applied whenever using the theory to develop, implement, or evaluate health care services and access more generally. © The Author(s) 2015.

The definition of accessible coherence is proposed. Through local measurement on the other subsystem and one-way classical communication, a subsystem can access more coherence than the coherence of its density matrix. Based on the local accessible coherence, the part that cannot be locally accessed is also studied, which we call it remaining coherence. We study how the bipartite coherence is distributed by partition for both l1 norm coherence and relative entropy coherence, and the expressions for local accessible coherence and remaining coherence are derived. We also study some examples to illustrate the distribution.
Solar energy programs are entering a critical transitional period as we move from the initial marketing of solar technologies into a phase of widespread commercialization. We face the dual challenge of trying to get enough solar systems in place fast enough to prove solar is a viable alternative, while trying to ensure the systems are designed and installed properly, proving the energy savings as promised. This is a period of both great opportunity and high risk as the field becomes crowded with new solar cheerleaders and supporters but seldom enough competent players. The status of existing and proposed programs for the accelerated commercialization of solar energy in California is described.

The Tiber PRT proposal tries to answer the competition questions with the definition of a provocative idea: a Personal Rapid transit System on the Tiber river banks. The project is located in the central section of the Tiber river and aims at the renewal of the river banks with the insertion of a Personal Rapid Transit infrastructure. The project area include the riverbank of Tiber from Rome Transtevere RFI station to Piazza del Popolo, an area where main touristic and leisure attractions are located. The intervention area is actually no used by the city users and residents and constitute itself a strong barrier in the heart of the historic city.

A disclosed example method involves performing simultaneous data accesses on at least first and second independently selectable logical sub-ranks to access first data via a wide internal data bus in a memory device. The memory device includes a translation buffer chip, memory chips in independently selectable logical sub-ranks, a narrow external data bus to connect the translation buffer chip to a memory controller, and the wide internal data bus between the translation buffer chip and the memory chips. A data access is performed on only the first independently selectable logical sub-rank to access second data via the wide internal data bus. The example method also involves locating a first portion of the first data, a second portion of the first data, and the second data on the narrow external data bus during separate data transfers.

Although serious efforts are made internationally and nationally, it is a slow process to make our physical environment accessible. In the actual design process, architects play a major role. But what kinds of knowledge, including research-based knowledge, do practicing architects make use of when...... designing accessible environments? The answer to the question is crucially important since it affects how knowledge is distributed and how accessibility can be ensured. In order to get first-hand knowledge about the design process and the sources from which they gain knowledge, 11 qualitative interviews...... were conducted with architects with experience of designing for accessibility. The analysis draws on two theoretical distinctions. The first is research-based knowledge versus knowledge used by architects. The second is context-independent knowledge versus context-dependent knowledge. The practitioners...
The Internet lets us share perfect copies of our work with a worldwide audience at virtually no cost. We take advantage of this revolutionary opportunity when we make our work "open access": digital, online, free of charge, and free of most copyright and licensing restrictions. Open access is made possible by the Internet and copyright-holder consent, and many authors, musicians, filmmakers, and other creators who depend on royalties are understandably unwilling to give their consent. But for 350 years, scholars have written peer-reviewed journal articles for impact, not for money, and are free to consent to open access without losing revenue. In this concise introduction, Peter Suber tells us what open access is and isn't, how it benefits authors and readers of research, how we pay for it, how it avoids copyright problems, how it has moved from the periphery to the mainstream, and what its future may hold. Distilling a decade of Suber's influential writing and thinking about open access, this is the indispe...
Full Text Available Uganda's economy has great potential. Endowed with significant natural resources, including ample fertile land, regular rainfall, and mineral deposits, it appeared poised for rapid economic growth and development at independence. However, chronic political instability and erratic economic management produced a record of persistent economic decline that left Uganda among the world's poorest and least-developed countries (United States, Bureau of African Affairs 2007. This situation can be averted by effectively promoting the involvement of the engine of economic growth, the SMEs in national and international businesses. The international involvement of SMEs requires accurate and adequate access to relevant business information. Based on that, a study was conducted to assess the problems SMEs face in accessing business information in Uganda. The study using a descriptive design with survey research techniques among others examined the problems SMEs in northern Uganda face in accessing business information; identified problems information providers face in providing business information to the SMEs in northern Uganda and established whether SMEs in northern Uganda use public libraries in accessing business information. The paper reports on among others the proposed strategic interventions for business information to be accessed by the SMEs . The paper concludes that there is a need for Uganda and, in particular, northern Uganda to develop a strategy for business information access by the SMEs.

Full Text Available Within the challenging environment of intelligent transportation systems (ITS, networked control systems such as platooning guidance of autonomous vehicles require innovative mechanisms to provide real-time communications. Although several proposals are currently under discussion, the design of a rapid, efficient, flexible, and reliable medium access control mechanism which meets the specific constraints of such real-time communications applications remains unsolved in this highly dynamic environment. However, cognitive radio (CR combines the capacity to sense the radio spectrum with the flexibility to adapt to transmission parameters in order to maximize system performance and has thus become an effective approach for the design of dynamic spectrum access (DSA mechanisms. This paper presents the enhanced noncooperative cognitive division multiple access (ENCCMA proposal combining time division multiple access (TDMA and frequency division multiple access (FDMA schemes with CR techniques to obtain a mechanism fulfilling the requirements of real-time communications. The analysis presented here considers the IEEE WAVE and 802.11p as reference standards; however, the proposed medium access control (MAC mechanism can be adapted to operate on the physical layer of different standards. The mechanism also offers the advantage of avoiding signaling, thus enhancing system autonomy as well as behavior in adverse scenarios.
Preparation of magnetic graphene/mesoporous silica composites with phenyl-functionalized pore-walls as the restricted access matrix solid phase extraction adsorbent for the rapid extraction of parabens from water-based skin toners.
Feng, Jianan; He, Xinying; Liu, Xiaodan; Sun, Xueni; Li, Yan
In this work, phenyl-functionalized magnetic graphene/mesoporous silica composites (MG-mSiO2-Ph) were prepared and applied as restricted access matrix solid phase extraction (RAM-SPE) adsorbents to determine the parabens in commercially available retail cosmetics. MG-mSiO2-Ph composites were synthesized by a surfactant-mediated co-condensation reaction in which mesoporous silica with phenyl-functionalized pore-walls was coated on a magnetic graphene sheet. The obtained nano-composites were proven to be of sufficient quality for an ideal RAM-SPE adsorbent with a large specific surface area of 369m(2)g(-1), uniform mesopores of 2.8nm, and special phenyl-functionalized pore-walls. Parabens, such as methyl paraben, ethyl paraben and propyl paraben, were extracted from water-based skin toners using one step of the RAM-SPE and were then analysed by a HPLC-DAD system. The SPE conditions were optimized by studying the parameters, such as the adsorbent amount, elution solvent type, adsorption time and desorption time, that influence the extraction efficiency. For each analyte, there were good linearities of approximately 0.10-120μgmL(-1) with determination coefficients (R(2))>0.995. The sensitivity was as low as 0.01-0.025μgmL(-1) for the LOD, and the percent recoveries were 98.37-105.84%. The intra-day and inter-day RSDs were 1.44-6.11% (n=6) and 3.12-11.70% (n=6), respectively. The results indicated that this method with novel RAM-SPE adsorbents is sensitive and convenient. The results also offered an attractive alternative for the extraction and determination of paraben preservatives in a complex matrix, such as cosmetics. Copyright © 2016 Elsevier B.V.

Full Text Available A recursive maximum-likelihood (RML algorithm for channel estimation under rapidly fading channel and colored noise in a multicarrier code-division multiple-access (MC-CDMA system is proposed in this paper. A moving-average model with exogenous input (MAX is given to describe the transmission channel and colored noise. Based on the pseudoregression method, the proposed RML algorithm can simultaneously estimate the parameters of channel and colored noise. Following the estimation results, these parameters can be used to enhance the minimum mean-square error (MMSE equalizer. Considering high-speed mobile stations, a one-step linear trend predictor is added to improve symbol detection. Simulation results indicate that the proposed RML estimator can track the channel more precisely than the conventional estimator. Meanwhile, the performance of the proposed enhanced MMSE equalizer is robust to the rapidly Rayleigh fading channel under colored noise in the MC-CDMA systems.

The integration of digital technology into everyday lives of young people has become widespread. It is not known whether and how technology influences barriers and facilitators to healthcare, and whether and how young people navigate between face-to-face and virtual healthcare. To provide new knowledge essential to policy and practice, we designed a study that would explore health system access and navigation in the digital age. The study objectives are to: (1) describe experiences of young people accessing and navigating the health system in New South Wales (NSW), Australia; (2) identify barriers and facilitators to healthcare for young people and how these vary between groups; (3) describe health system inefficiencies, particularly for young people who are marginalised; (4) provide policy-relevant knowledge translation of the research data. This mixed methods study has four parts, including: (1) a cross-sectional survey of young people (12-24 years) residing in NSW, Australia; (2) a longitudinal, qualitative study of a subsample of marginalised young people (defined as young people who: identify as Aboriginal and/or Torres Strait Islander; are experiencing homelessness; identify as sexuality and/or gender diverse; are of refugee or vulnerable migrant background; and/or live in rural or remote NSW); (3) interviews with professionals; (4) a knowledge translation forum. Ethics approvals were sought and granted. Data collection commenced in March 2016 and will continue until June 2017. This study will gather practice and policy-relevant intelligence about contemporary experiences of young people and health services, with a unique focus on five different groups of marginalised young people, documenting their experiences over time. Access 3 will explore navigation around all levels of the health system, determine whether digital technology is integrated into this, and if so how, and will translate findings into policy-relevant recommendations. © Article author(s) (or

We proposed methods for the synthesis and purification of 2-[18F]fluoromalondialdehyde, which will be a readily accessible synthon for bioconjugation. Our achievements in these areas will specifically address a stated goal of the DOE providing a transformational technology for macromolecule radiolabeling. Accomplishment of our aims will serve both DOE mission-related research as well as nuclear medicine research supported by the NIH and industry. At the heart of our proposal is the aim to “improve synthetic methodology for rapidly and efficiently incorporating radionuclides into a wide range of organic compounds.”
One of the major challenges in effectively operating a cloud radio access network (C-RAN) is the excessive overhead signaling and computation load that scale rapidly with the size of the network. In this paper, the exploitation of location information of the mobile devices is proposed to address this challenge. We consider an approach in which location-assisted channel state information (CSI) acquisition methods are introduced to complement conventional pilot-based CSI acquisition methods and avoid excessive overhead signaling. A low-complexity algorithm is designed to maximize the sum rate. An adaptive algorithm is also proposed to address the uncertainty issue in CSI acquisition. Both theoretical and numerical analyses show that location information provides a new dimension to improve throughput for next-generation massive cooperative networks.

Multimedia social networks (MMSNs) have provided a convenient way to share multimedia contents such as images, videos, blogs, etc. Contents shared by a person can be easily accessed by anybody else over the Internet. However, due to various privacy, security, and legal concerns people often want to selectively share the contents only with their friends, family, colleagues, etc. Access control mechanisms play an important role in this situation. With access control mechanisms one can decide the persons who can access a shared content and who cannot. But continuously growing content uploads and accesses, fine grained access control requirements (e.g. different access control parameters for different parts in a picture), and specific access control requirements for multimedia contents can make the time complexity of access control to be very large. So, it is important to study an efficient access control mechanism suitable for MMSNs. In this chapter we present an efficient bit-vector transform based access control mechanism for MMSNs. The proposed approach is also compatible with other requirements of MMSNs, such as access rights modification, content deletion, etc. Mathematical analysis and experimental results show the effectiveness and efficiency of our proposed approach.
Full Text Available The ability of an Internet user to access data collected about himself as a result of his online activity is a key privacy safeguard. Online, data access has been overshadowed by other protections such as notice and choice. This paper describes attitudes about data access. 873 US and Irish Internet users participated in a survey designed to examine views on data access to information held by online companies and data brokers. We observed low levels of awareness of access mechanisms along with a high desire for access in both participant groups. We tested three proposed access systems in keeping with industry programs and regulatory proposals. User response was positive. We conclude that access remains an important privacy protection that is inadequately manifested in practice. Our study provides insight for lawmakers and policymakers, as well as computer scientists who implement these systems.

The author focuses on a new rapidly spreading practice of publication in open-access journals. The pros and cons of open-access journals are discussed. Publishing in these journals may be cost prohibitive for educators and junior faculty members. Some authors may be lured by the ease of publishing in open-access journals (and their, at times, inflated self-description, e.g., "international", "scientific"), and their possibly valuable contributions will escape the attention of Academic Psychiatry readership in the vast sea of open-access journals. The readership may be flooded with a large number of low-quality articles (maybe not even properly peer-reviewed) from open-access journals. It may take some time to sort out what is and what is not relevant and useful. Open-access publishing represents a problematic and controversial practice and may be associated with a conflict of interest for the editors and publishers of these journals.

Full Text Available O trabalho propõe questionamento e criticidade quanto à adoção de expressões como “biblioteca virtual” ou “biblioteca digital” para conceituar o modelo de organização da informação na contemporaneidade. Contextualiza, histórica e culturalmente, as bibliotecas de modo a apresentar definições, tipologias e amplitude de definições de vários autores. Propõe o reescalonamento das bibliotecas pelo vetor do acesso à informação, haja vista a formação de redes para transferência de informações, a reconfiguração do tempo e do espaço ora vigentes e a forma com que as tecnologias computacionais afetam a criação, o uso, a gestão e o fluxo da informação, de modo a serem abordadas as bibliotecas in loco, em tempo real e híbridas. Propõe-se que, qualquer que seja a unidade documentária a ser disponibilizada, os atuais projetos de construção de bibliotecas em tempo real deverão, inevitavelmente, requerer um processo de revisão dos modelos ultimamente em uso, abarcando, inclusive, as funções dos profissionais envolvidos, a preservação, legibilidade e acessibilidade de documentos digitais por programas específicos.

This installment of “The Balance Point” presents articles written by three Open Access advocates, outlining the SCOAP3 proposal, benefits of participation, and some of the roles libraries, publishers and scientists can play in making important changes to scholarly communication. Contributors discuss scalability and transferability issues of SCOAP3, as well as other matters of concern.
Purpose: This study investigated the effects of lexical access speed and letter access speed on reading fluency and reading comprehension. We hypothesized that 1) letter access speed would correlate with reading fluency but not comprehension, while 2) lexical access speed would influence reading...... comprehension. For readers who are struggling with recoding, most of the reading effort is probably tied up with recoding, leaving little to be explained by lexical access. Therefore we expected that 3) lexical access speed would primarily predict reading fluency for readers who were no longer struggling...... with recoding. Method: 85 Grade 5 students completed tasks of reading accuracy, fluency, and comprehension. In addition they were tested on isolated letter naming and isolated picture naming tasks as measures of letter and lexical access speed. All items in both naming tasks were unique. Parallel serial rapid...

Full Text Available With the rapid rise of Internet of Things in public domain, people expect fast, reliable and on-demand home security via the Internet. However, existing remote home surveillance systems place a very rigid constraint on authentication and require customized hardware and software. In this paper we have proposed an ingenious and reliable internet based, home access system for smart homes that can be easily deployed on generic hardware. The proposed architecture uses popular email service providers to notify and update the user about the home access. It sends an email to the owner with the attached picture of the person who is at the door. It also incorporates a protected mechanism to give access of the door to a remote user by responding to that email. It essentially means that we can view and give access to the person at our door via sending and receiving an email. Furthermore, an image processing based mechanism has also been incorporated to provide access without email, to few selected personnel who are trusted by the owner. It works by capturing and comparing the visitor's image with the stored images in the database. Perceptual hashing or fingerprint matching algorithm is used for comparison purposes. Similarity percentage based on hamming distance was evaluated, and the similarity threshold for providing access was set. The simulations were performed in rigorous environment. The efficiency of the hashing algorithm was found to be 97% at the similarity threshold of 95%. The results validate that the average latency is only 155 ms with low standard deviation. The CPU utilization remained quite low with a minimum value of 10 MHz and a maximum value of 30 MHz when the payload size of the sent mail was increased to 1500 kB. Thus, the proposed system can be used for developing a larger low power infrastructure.

Establishing early warning systems for anthrax attacks is crucial in biodefense. Despite numerous studies for decades, the limited sensitivity of conventional biochemical methods essentially requires preprocessing steps and thus has limitations to be used in realistic settings of biological warfare. We present an optical method for rapid and label-free screening of Bacillus anthracis spores through the synergistic application of holographic microscopy and deep learning. A deep convolutional neural network is designed to classify holographic images of unlabeled living cells. After training, the network outperforms previous techniques in all accuracy measures, achieving single-spore sensitivity and subgenus specificity. The unique "representation learning" capability of deep learning enables direct training from raw images instead of manually extracted features. The method automatically recognizes key biological traits encoded in the images and exploits them as fingerprints. This remarkable learning ability makes the proposed method readily applicable to classifying various single cells in addition to B. anthracis, as demonstrated for the diagnosis of Listeria monocytogenes, without any modification. We believe that our strategy will make holographic microscopy more accessible to medical doctors and biomedical scientists for easy, rapid, and accurate point-of-care diagnosis of pathogens.

The development of mobile computing, cloud computing and distributed computing meets the growing individual service needs. Facing with complex application system, it's an urgent problem to ensure real-time, dynamic, and fine-grained data access control. By analyzing common data access control models, on the basis of mandatory access control model, the paper proposes a service-oriented access control model. By regarding system services as subject and data of databases as object, the model defines access levels and access identification of subject and object, and ensures system services securely to access databases.
This work uses simple two-body orbital dynamics to initially determine the kinematic access for a ballistic vehicle. Primarily this analysis was developed to assess when a rocket body might conjunct with an orbiting satellite platform. A family of access opportunities can be represented as a volume for a specific rocket relative to its launch platform. Alternately, the opportunities can be represented as a geographical footprint relative to aircraft or satellite position that encompasses all possible launcher locations for a specific rocket. A thrusting rocket is treated as a ballistic vehicle that receives all its energy at launch and follows a coasting trajectory. To do so, the rocket's burnout energy is used to find its equivalent initial velocity for a given launcher's altitude. Three kinematic access solutions are then found that account for spherical Earth rotation. One solution finds the maximum range for an ascent-only trajectory while another solution accommodates a descending trajectory. In addition, the ascent engagement for the descending trajectory is used to depict a rapid access scenario. These preliminary solutions are formulated to address ground-, sea-, or air-launched vehicles.

RAPID is a methodology and software system to define a class of airplane configurations and directly evaluate surface grids, volume grids, and grid sensitivity on and about the configurations. A distinguishing characteristic which separates RAPID from other airplane surface modellers is that the output grids and grid sensitivity are directly applicable in CFD analysis. A small set of design parameters and grid control parameters govern the process which is incorporated into interactive software for 'real time' visual analysis and into batch software for the application of optimization technology. The computed surface grids and volume grids are suitable for a wide range of Computational Fluid Dynamics (CFD) simulation. The general airplane configuration has wing, fuselage, horizontal tail, and vertical tail components. The double-delta wing and tail components are manifested by solving a fourth order partial differential equation (PDE) subject to Dirichlet and Neumann boundary conditions. The design parameters are incorporated into the boundary conditions and therefore govern the shapes of the surfaces. The PDE solution yields a smooth transition between boundaries. Surface grids suitable for CFD calculation are created by establishing an H-type topology about the configuration and incorporating grid spacing functions in the PDE equation for the lifting components and the fuselage definition equations. User specified grid parameters govern the location and degree of grid concentration. A two-block volume grid about a configuration is calculated using the Control Point Form (CPF) technique. The interactive software, which runs on Silicon Graphics IRIS workstations, allows design parameters to be continuously varied and the resulting surface grid to be observed in real time. The batch software computes both the surface and volume grids and also computes the sensitivity of the output grid with respect to the input design parameters by applying the precompiler tool

Electronic, software-managed mechanisms using, for example, radio-frequency identification (RFID) cards, enable great flexibility in specifying access control policies to physical spaces. For example, access rights may vary based on time of day or could differ in normal versus emergency situations. With such fine-grained control, understanding and reasoning about what a policy permits becomes surprisingly difficult requiring knowledge of permission levels, spatial layout, and time. In this paper, we present a formal modeling framework, called AccessNets, suitable for describing a combination of access permissions, physical spaces, and temporal constraints. Furthermore, we provide evidence that model checking techniques are effective in reasoning about physical access control policies. We describe our results from a tool that uses reachability analysis to validate security policies.

The RAPID3 score is the sum of three 0-10 patient self-report scores: pain, functional impairment on MDHAQ, and patient global estimate. It requires 5 seconds for scoring and can be used in all rheumatologic conditions, although it has mostly been used in rheumatoid arthritis where cutoffs for low disease activity (12/30) have been set. A RAPID3 score of ≤ 3/30 with 1 or 0 swollen joints (RAPID3 ≤ 3 + ≤ SJ1) provides remission criteria comparable to Boolean, SDAI, CDAI, and DAS28 remission criteria, in far less time than a formal joint count. RAPID3 performs as well as the DAS28 in separating active drugs from placebos in clinical trials. RAPID3 also predicts subsequent structural disease progression. RAPID3 can be determined at short intervals at home, allowing the determination of the area under the curve of disease activity between two visits and flare detection. However, RAPID3 should not be seen as a substitute for DAS28 and face to face visits in routine care. Monitoring patient status with only self-report information without a rheumatologist's advice (including joints and physical examination, and consideration of imaging and laboratory tests) may indeed be as undesirable for most patients than joint examination without a patient questionnaire. Conversely, combining the RAPID3 and the DAS28 may consist in faster or more sensitive confirmation that a medication is effective. Similarly, better enquiring of most important concerns of patients (pain, functional status and overall opinion on their disorder) should reinforces patients' confidence in their rheumatologist and treatments.

This document is the first of two volumes describing the ATF2 project. The present volume discusses the technical justification for ATF2 and presents a design description. Since the International Committee for Future Accelerator (ICFA) decision on the choice of technology, a world-wide collaboration on the design of the International Linear Collider (ILC) has rapidly progressed . The formation of the Global Design Effort (GDE) will accelerate the work towards a final design. An important technical challenge is obviously the high gradient acceleration but what is similarly challenging is the collision of extremely small beams of a few nanometer size. The latter challenge has three distinct issues: creating small emittance beams, preserving the emittance during acceleration and transport, and focusing the beams to nanometers. Most studies have been done using computer simulations but many issues still remain that require experimental verification. Accelerator Test Facility (ATF) at KEK was built to create small emittance beams, and succeeded in obtaining an emittance that almost satisfies the ILC requirements . In this proposal we present a project, ATF2, which addresses the focusing of the beam into a nanometer spot. The ATF2 project will extend the extraction beamline of the ATF with an ILC-type final focus system to create a tightly focused, stable beam by making use of the small emittance of the ATF. The layout is shown in Figure 1.1. In the longer term, the ATF2 project would also provide invaluable input for the CLIC design of a future multi-TeV collider.

In the fog computing environment, the encrypted sensitive data may be transferred to multiple fog nodes on the edge of a network for low latency; thus, fog nodes need to implement a search over encrypted data as a cloud server. Since the fog nodes tend to provide service for IoT applications often running on resource-constrained end devices, it is necessary to design lightweight solutions. At present, there is little research on this issue. In this paper, we propose a fine-grained owner-forced data search and access authorization scheme spanning user-fog-cloud for resource constrained end users. Compared to existing schemes only supporting either index encryption with search ability or data encryption with fine-grained access control ability, the proposed hybrid scheme supports both abilities simultaneously, and index ciphertext and data ciphertext are constructed based on a single ciphertext-policy attribute based encryption (CP-ABE) primitive and share the same key pair, thus the data access efficiency is significantly improved and the cost of key management is greatly reduced. Moreover, in the proposed scheme, the resource constrained end devices are allowed to rapidly assemble ciphertexts online and securely outsource most of decryption task to fog nodes, and mediated encryption mechanism is also adopted to achieve instantaneous user revocation instead of re-encrypting ciphertexts with many copies in many fog nodes. The security and the performance analysis show that our scheme is suitable for a fog computing environment.

This study aims to improve Wikipedia usability for the blind and promote the application of standards relating to Web accessibility and usability. First, accessibility and usability of Wikipedia home, search result and edit pages are analysed using the JAWS screen reader; next, suggestions for improving interaction are proposed and a new Wikipedia editing interface built. Most of the improvements were obtained using the Accessible Rich Internet Applications (WAI-ARIA) suite, developed by the World Wide Web Consortium (W3C) within the framework of the Web Accessibility Initiative (WAI). Last, a scenario of use compares interaction of blind people with the original and the modified interfaces. Our study highlights that although all contents are accessible via screen reader, usability issues exist due to the user's difficulties when interacting with the interface. The scenario of use shows how building an editing interface with the W3C WAI-ARIA suite eliminates many obstacles that can prevent blind users from actively contributing to Wikipedia. The modified Wikipedia editing page is simpler to use via a screen reader than the original one because ARIA ensures a page overview, rapid navigation, and total control of what is happening in the interface.

Developing an interdisciplinary understanding of human and environmental interactions with water requires access to a variety of data kinds collected by various organizations. The CUAHSI Hydrologic Information System (HIS) is a standards-based, services-oriented architecture designed for time-series data. Such data represents an important type of data in water studies. Through the efforts of HIS, a standard transmission language, WaterML2, has been adopted by the Open Geospatial Consortium and is under consideration by the World Meteorologic Organization as an international standards. Web services have also been developed to retrieve data and metadata. HIS is completed with a metadata catalog, hosted by San Diego Supercomputing Center, which indexes more than 20 million time series provided from over 90 different services. This catalog is supported through a hierarchically organized controlled vocabulary that is open for community input and mediation. Data publishers include federal agencies, universities, state agencies, and non-profit organizations such as watershed associations. Accessing data from such a broad spectrum of sources through a uniform service standard promises to truly transform the way in which hydrologic research is done. CUAHSI HIS is a large-scale prototype at this time, but a proposal is under consideration by the National Science Foundation to operationalize HIS through a data facility, tentatively called the CUAHSI Water Data Center. Establishing HIS is an important step to enable research into human-environment interactions with water, but it is only one step. Other data structures will need to be made accessible and interoperable to support this research. Some data—such as two-dimensional GIS coverages—already have widely used standards for transmission and sharing. The US Federal government has long operated a clearinghouse for federal geographic data that is now being augmented with other services such as ArcGIS OnLine. Other data

Nowadays, access control is an indispensable part of the Personal Health Record and supplies for its confidentiality by enforcing policies and rules to ensure that only authorized users gain access to requested resources in the system. In other words, the access control means protecting patient privacy in healthcare systems. Attribute-Based Access Control (ABAC) is a new access control model that can be used instead of other traditional types of access control such as Discretionary Access Control, Mandatory Access Control, and Role-Based Access Control. During last five years ABAC has shown some applications in both recent academic fields and industry purposes. ABAC by using user’s attributes and resources, makes a decision according to an access request. In this paper, we propose an ABAC framework for healthcare system. We use the engine of ABAC for rendering and enforcing healthcare policies. Moreover, we handle emergency situations in this framework.

Full Text Available The main focus of the proposed research is maintaining the security of a network. Extranet is a popular network among most of the organizations where network access is provided to a selected group of outliers. Limiting access to an extranet can be carried out using Access Control Lists ACLs method. However handling the workload of ACLs is an onerous task for the router. The purpose of the proposed research is to improve the performance and to solidify the security of the ACLs used in a small organization. Using a high performance computer as a dedicated device to share and handle the router workload is suggested in order to increase the performance of the router when handling ACLs. Methods of detecting and directing sensitive data is also discussed in this paper. A framework is provided to help increase the efficiency of the ACLs in an organization network using the above mentioned procedures thus helping the organizations ACLs performance to be improved to be more secure and the system to perform faster. Inbuilt methods of Windows platform or Software for open source platforms can be used to make a computer function as a router. Extended ACL features allow the determining of the type of packets flowing through the router. Combining these mechanisms allows the ACLs to be improved and perform in a more efficient manner.

With 1.4 billion people lacking electricity to light their homes and provide other basic services, or to conduct business, and all of humanity (and particularly the poor) are in need of a decarbonized energy system can close the energy access gap and protect the global climate system. With particular focus on addressing the energy needs of the underserved, we present an analytical framework informed by historical trends and contemporary technological, social, and institutional conditions that clarifies the heterogeneous continuum of centralized on-grid electricity, autonomous mini- or community grids, and distributed, individual energy services. We find that the current day is a unique moment of innovation in decentralized energy networks based on super-efficient end-use technology and low-cost photovoltaics, supported by rapidly spreading information technology, particularly mobile phones. Collectively these disruptive technology systems could rapidly increase energy access, contributing to meeting the Millennium Development Goals for quality of life, while simultaneously driving action towards low-carbon, Earth-sustaining, energy systems.
Full Text Available As computer technologies become pervasive, the need for access control mechanisms grow. The purpose of an access control is to limit the operations that a computer system user can perform. Thus, access control ensures to prevent an activity which can lead to a security breach. For the success of Semantic Web, that allows machines to share and reuse the information by using formal semantics for machines to communicate with other machines, access control mechanisms are needed. Access control mechanism indicates certain constraints which must be achieved by the user before performing an operation to provide a secure Semantic Web. In this work, unlike traditional access control mechanisms, an "Ontology Based Access Control" mechanism has been developed by using Semantic Web based policies. In this mechanism, ontologies are used to model the access control knowledge and domain knowledge is used to create policy ontologies.

This paper investigates the performance of a cognitive radio transceiver that can monitor multiple channels and opportunistically use any one of them should it be available. In our work, we propose and compare two different opportunistic channel access schemes. The first scheme applies when the secondary user (SU) has access to only one channel. The second scheme applies when the SU has access to multiple channels but can at a given time monitor and access only one channel. Two switching strategies, namely the switch and examine and the switch and stay strategies, are proposed. For these proposed access schemes, we investigate their performance by deriving the analytical expression of the novel metric of the average access duration and the average waiting time and based on these two metrics a time average SU throughput formula is proposed to predict the performance of the secondary cognitive system. © 2012 ICST.

With the rapid development of big data and Internet of things (IOT), the number of networking devices and data volume are increasing dramatically. Fog computing, which extends cloud computing to the edge of the network can effectively solve the bottleneck problems of data transmission and data storage. However, security and privacy challenges are also arising in the fog-cloud computing environment. Ciphertext-policy attribute-based encryption (CP-ABE) can be adopted to realize data access control in fog-cloud computing systems. In this paper, we propose a verifiable outsourced multi-authority access control scheme, named VO-MAACS. In our construction, most encryption and decryption computations are outsourced to fog devices and the computation results can be verified by using our verification method. Meanwhile, to address the revocation issue, we design an efficient user and attribute revocation method for it. Finally, analysis and simulation results show that our scheme is both secure and highly efficient.

The proposed Yucca Mountain repository site currently lacks rail access. The nearest mainline railroad is almost 100 miles away. Absence of rail access could result in many thousands of truck shipments of spent nuclear fuel and high-level radioactive waste. Direct rail access to the repository could significantly reduce the number of truck shipments and total shipments. The U.S. Department of Energy (DOE) identified five potential rail access corridors, ranging in length from 98 miles to 323 miles, in the Final Environmental Impact Statement (FEIS) for Yucca Mountain. The FEIS also considers an alternative to rail spur construction, heavy-haul truck (HHT) delivery of rail casks from one of three potential intermodal transfer stations. The authors examine the feasibility and cost of the five rail corridors, and DOE's alternative proposal for HHT transport. The authors also address the potential for rail shipments through the Las Vegas metropolitan area.
The direct connection of information, captured in forms such as CAD databases, to the factory floor is enabling a revolution in manufacturing. Rapid response to very dynamic market conditions is becoming the norm rather than the exception. In order to provide economical rapid fabrication of small numbers of variable products, one must design with manufacturing constraints in mind. In addition, flexible manufacturing systems must be programmed automatically to reduce the time for product change over in the factory and eliminate human errors. Sensor based machine control is needed to adapt idealized, model based machine programs to uncontrolled variables such as the condition of raw materials and fabrication tolerances.
Full Text Available In January 2009, the Colorado Association of Libraries (CAL suspended publication of its print quarterly journal, Colorado Libraries, as a cost-saving measure in a time of fiscal uncertainty. Printing and mailing the journal to its 1300 members cost CAL more than $26,000 per year. Publication of the journal was placed on an indefinite hiatus until the editorial staff proposed an online, open access format a year later. The benefits to migrating to open access included: significantly lower costs; a green platform; instant availability of content; a greater level of access to users with disabilities; and a higher level of visibility of the journal and the association. The editorial staff chose Drupal, including the E-journal module, and while Drupal is notorious for its steep learning curve—which exacerbated delays to content that had been created before the publishing hiatus—the fourth electronic issue was published recently at coloradolibrariesjournal.org. This article will discuss both the benefits and challenges of transitioning to an open access model and the choice Drupal as a platform over other more established journal software options.

Access to point-of-care (POC) diagnostics services is essential for ensuring rapid disease diagnosis, management, control, and surveillance. POC testing services can improve access to healthcare especially where healthcare infrastructure is weak and access to quality and timely medical care is a challenge. Improving the accessibility and efficiency of POC diagnostics services, particularly in resource-limited settings, may be a promising route to improving healthcare outcomes. In this review, the accessibility of POC testing is defined as the distance/proximity to the nearest healthcare facility for POC diagnostics service. This review provides an overview of the impact of POC diagnostics on healthcare outcomes in low- and middle-income countries (LMICs) and factors contributing to the accessibility of POC testing services in LMICs, focusing on characteristics of the supply chain management and quality systems management, characteristics of the geographical location, health infrastructure, and an enabling policy framework for POC diagnostics services. Barriers and challenges related to the accessibility of POC diagnostics in LMICs were also discussed. Bearing in mind the reported barriers and challenges as well as the disease epidemiology in LMICs, we propose a lean and agile supply chain management framework for improving the accessibility and efficiency of POC diagnostics services in these settings.

The efficient data access of streaming vehicle data is the foundation of analyzing, using and mining vehicle data in smart cities, which is an approach to understand traffic environments. However, the number of vehicles in urban cities has grown rapidly, reaching hundreds of thousands in number. Accessing the mass streaming data of vehicles is hard and takes a long time due to limited computation capability and backward modes. We propose an efficient streaming spatio-temporal data access based on Apache Storm (ESDAS) to achieve real-time streaming data access and data cleaning. As a popular streaming data processing tool, Apache Storm can be applied to streaming mass data access and real time data cleaning. By designing the Spout/bolt workflow of topology in ESDAS and by developing the speeding bolt and other bolts, Apache Storm can achieve the prospective aim. In our experiments, Taiyuan BeiDou bus location data is selected as the mass spatio-temporal data source. In the experiments, the data access results with different bolts are shown in map form, and the filtered buses' aggregation forms are different. In terms of performance evaluation, the consumption time in ESDAS for ten thousand records per second for a speeding bolt is approximately 300 milliseconds, and that for MongoDB is approximately 1300 milliseconds. The efficiency of ESDAS is approximately three times higher than that of MongoDB.

Full Text Available Professionals are constantly seeking qualification and consequently increasing their knowledge in their area of expertise. Thus, it is interesting to develop a computer system that knows its users and their work history. Using this information, even in the case of professional role change, the system could allow the renewed authorization for activities, based on previously authorized use. This article proposes a model for user access control that is embedded in a context-aware environment. The model applies the concept of trails to manage access control, recording activities usage in contexts and applying this history as a criterion to grant new accesses. Despite the fact that previous related research works consider contexts, none of them uses the concept of trails. Hence, the main contribution of this work is the use of a new access control criterion, namely, the history of previous accesses (trails. A prototype was implemented and applied in an evaluation based on scenarios. The results demonstrate the feasibility of the proposal, allowing for access control systems to use an alternative way to support access rights.

The rapid increase of genome-wide datasets on gene expression, chromatin states, and transcription factor (TF) binding locations offers an exciting opportunity to interpret the information encoded in genomes and epigenomes. This task can be challenging as it requires joint modeling of context-specific activation of cis-regulatory elements (REs) and the effects on transcription of associated regulatory factors. To meet this challenge, we propose a statistical approach based on paired expression and chromatin accessibility (PECA) data across diverse cellular contexts. In our approach, we model (i) the localization to REs of chromatin regulators (CRs) based on their interaction with sequence-specific TFs, (ii) the activation of REs due to CRs that are localized to them, and (iii) the effect of TFs bound to activated REs on the transcription of target genes (TGs). The transcriptional regulatory network inferred by PECA provides a detailed view of how trans- and cis-regulatory elements work together to affect gene expression in a context-specific manner. We illustrate the feasibility of this approach by analyzing paired expression and accessibility data from the mouse Encyclopedia of DNA Elements (ENCODE) and explore various applications of the resulting model.

A crucial open problem inS large-scale quantum networks is how to efficiently transmit quantum data among many pairs of users via a common data-transmission medium. We propose a solution by developing a quantum code division multiple access (q-CDMA) approach in which quantum information is chaotically encoded to spread its spectral content, and then decoded via chaos synchronization to separate different sender-receiver pairs. In comparison to other existing approaches, such as frequency division multiple access (FDMA), the proposed q-CDMA can greatly increase the information rates per channel used, especially for very noisy quantum channels.

Access to modern contraception has become a recognized human right, improving the health and well-being of women, families and societies worldwide. However, contraceptive access remains uneven. Irregular contraceptive supply, limited numbers of service delivery points and specific geographic, economic, informational, psychosocial and administrative barriers (including medical barriers) undermine access in many settings. Widening the range of providers enabled to offer contraception can improve contraceptive access, particularly where resources are most scarce. International efforts to remove medical barriers include the World Health Organization's Medical Eligibility Criteria. Based on the best available evidence, these criteria provide guidance for weighing the risks and benefits of contraceptive choice among women with specific clinical conditions. Clinical job aids can also improve access. More research is needed to further elucidate the pathways for expanding contraceptive access. Further progress in removing medical barriers will depend on systems for improving provider education and promoting evidence-based contraceptive service delivery.

Pathogen identification is a crucial first defense against bioterrorism. A major emphasis of our national biodefense strategy is to establish fast, accurate and sensitive assays for diagnosis of infectious diseases agents. Such assays will ensure early and appropriate treatment of infected patients. Rapid diagnostics can also support infection control measures, which monitor and limit the spread of infectious diseases agents. Many select agents are highly transmissible in the early stages of disease, and it is critical to identify infected patients and limit the risk to the remainder of the population and to stem potential panic in the general population. Nucleic acid-based molecular approaches for identification overcome many of the deficiencies associated with conventional culture methods by exploiting both large- and small-scale genomic differences between organisms. PCR-based amplification of highly conserved ribosomal RNA (rRNA) genes, intergenic sequences, and specific toxin genes is currently the most reliable approach for bacterial, fungal and many viral pathogenic agents. When combined with fluorescence-based oligonucleotide detection systems, this approach provides real-time, quantitative, high fidelity analysis capable of single nucleotide allelic discrimination (4). These probe systems offer rapid turn around time (<2 h) and are suitable for high throughput, automated multiplex operations that are critical for clinical diagnostic laboratories. In this pilot program, we have used molecular beacon technology invented at the Public health Research Institute to develop a new generation of molecular probes to rapidly detect important agents of infectious diseases. We have also developed protocols to rapidly extract nucleic acids from a variety of clinical specimen including and blood and tissue to for detection in the molecular assays. This work represented a cooperative research development program between the Kramer-Tyagi/Perlin labs on probe development

In the first essay, a theoretical model is developed to determine the time path of optimal access price in the telecommunications industry. Determining the optimal access price is an important issue in the economics of telecommunications. Setting a high access price discourages potential entrants; a low access price, on the other hand, amounts to confiscation of private property because the infrastructure already built by the incumbent is sunk. Furthermore, a low access price does not give the incumbent incentives to maintain the current network and to invest in new infrastructures. Much of the existing literature on access pricing suffers either from the limitations of a static framework or from the assumption that all costs are avoidable. The telecommunications industry is subject to high stranded costs and, therefore, to address this issue a dynamic model is imperative. This essay presents a dynamic model of one-way access pricing in which the compensation involved in deregulatory taking is formalized and then analyzed. The short run adjustment after deregulatory taking has occurred is carried out and discussed. The long run equilibrium is also analyzed. A time path for the Ramsey price is shown as the correct dynamic price of access. In the second essay, a theoretical model is developed to determine the time path of optimal access price for an infrastructure that is characterized by congestion and lumpy investment. Much of the theoretical literature on access pricing of infrastructure prescribes that the access price be set at the marginal cost of the infrastructure. In proposing this rule of access pricing, the conventional analysis assumes that infrastructure investments are infinitely divisible so that it makes sense to talk about the marginal cost of investment. Often it is the case that investments in infrastructure are lumpy and can only be made in large chunks, and this renders the marginal cost concept meaningless. In this essay, we formalize a model of
Full Text Available We all are aware of the organizational omnipresence. Projects within the organizations are ubiquitous too. Projects achieve their goals successfully if they are planned, scheduled, controlled and implemented well. The project lifecycle of initiating, planning, scheduling, controlling and implementing are very well-planned by project managers and the organizations. Successful projects have well-developed risk management plans to deal with situations impacting projects. Like any other organisation, a university does try to access funds for different purposes too. For such organisations, running a project is not the issue, rather getting a project proposal approved to fund a project is the key. Project proposal processing is done by the nodal office in every organisation. Usually, these nodal offices help in administration and submission of a project proposal for accessing funds. Seldom are these nodal project offices within the organizations facilitate a project proposal approval by proactively reaching out to the project managers. And as project managers prepare project proposals, little or no attention is made to prepare a project proposal risk plan so as to maximise project acquisition. Risk plans are submitted while preparing proposals but these risk plans cater to a requirement to address actual projects upon approval. Hence, a risk management plan for project proposal is either missing or very little effort is made to treat the risks inherent in project acquisition. This paper is an integral attempt to highlight the importance of risk treatment for project proposal stage as an extremely important step to preparing the risk management plan made for projects corresponding to their lifecycle phases. Several tools and techniques have been proposed in the paper to help and guide either the project owner (proposer or the main organisational unit responsible for project management.

The applications of polymer microneedles (MNs) into human skin emerged as an alternative of the conventional hypodermic needles. However, dissolving MNs require many minutes to be dissolved in the skin and typically have difficulty being fully inserted into the skin, which may lead to the low drug delivery efficiency. To address these issues, we introduce rapidly separating MNs that can rapidly deliver drugs into the skin in a minimally invasive way. For the rapidly separating MNs, drug loaded dissolving MNs are mounted on the top of solid MNs, which are made of biodegradable polylactic acid which eliminate the biohazardous waste. These MNs have sufficient mechanical strength to be inserted into the skin with the drug loaded tips fully embedded for subsequent dissolution. Compared with the traditional MNs, rapidly separating MNs achieve over 90% of drug delivery efficiency in 30s while the traditional MNs needs 2min to achieve the same efficiency. With the in vivo test in mice, the micro-holes caused by rapidly separating MNs can heal in 1h, indicating that the rapidly separating MNs are safe for future applications. These results indicate that the design of rapidly separating dissolvable MNs can offer a quick, high efficient, convenient, safe and potentially self-administered method of drug delivery. Polymer microneedles offer an attractive, painless and minimally invasive approach for transdermal drug delivery. However, dissolving microneedles require many minutes to be dissolved in the skin and typically have difficulty being fully inserted into the skin due to the skin deformation, which may lead to the low drug delivery efficiency. In this work we proposed rapidly separating microneedles which can deliver over 90% of drug into the skin in 30s. The in vitro and in vivo results indicate that the new design of these microneedles can offer a quick, high efficient, convenient and safe method for transdermal drug delivery.

Full Text Available In the very last years, optical access networks are growing very rapidly, from both the network operators and the research interests points of view. Fiber To The Home (FTTH is already a reality in plenty of real contexts and there has been a further stimulus to the proposal of new solutions and the investigation of new possibilities, in order to optimize network performance and reduce capital and operational expenditure. A complete and systematic overview of passive optical access networks is presented in this paper, concerning both the hot research topics and the main operative issues about the design guidelines and the deployment of Passive Optical Networks (PON architectures, nowadays the most commonly implemented approach to realize optical fiber links in the access networks. A comparison of advantages and disadvantages of different multiplexing techniques is discussed, with specific reference to WDM-based networks, almost universally considered as the enabling technology for future proof bandwidth requirements. An exhaustive summary is also given about the-state-of-the-art of modulation and encoding techniques recently proposed by the scientific community, as well as the open challenges (such as colorless and coolerless ONUs for telecom companies and international standardization compliance.

Call for Papers: Optical Access Networks With the wide deployment of fiber-optic technology over the past two decades, we have witnessed a tremendous growth of bandwidth capacity in the backbone networks of today's telecommunications infrastructure. However, access networks, which cover the "last-mile" areas and serve numerous residential and small business users, have not been scaled up commensurately. The local subscriber lines for telephone and cable television are still using twisted pairs and coaxial cables. Most residential connections to the Internet are still through dial-up modems operating at a low speed on twisted pairs. As the demand for access bandwidth increases with emerging high-bandwidth applications, such as distance learning, high-definition television (HDTV), and video on demand (VoD), the last-mile access networks have become a bandwidth bottleneck in today's telecommunications infrastructure. To ease this bottleneck, it is imperative to provide sufficient bandwidth capacity in the access networks to open the bottleneck and thus present more opportunities for the provisioning of multiservices. Optical access solutions promise huge bandwidth to service providers and low-cost high-bandwidth services to end users and are therefore widely considered the technology of choice for next-generation access networks. To realize the vision of optical access networks, however, many key issues still need to be addressed, such as network architectures, signaling protocols, and implementation standards. The major challenges lie in the fact that an optical solution must be not only robust, scalable, and flexible, but also implemented at a low cost comparable to that of existing access solutions in order to increase the economic viability of many potential high-bandwidth applications. In recent years, optical access networks have been receiving tremendous attention from both academia and industry. A large number of research activities have been carried out or

In Australia, rapid population ageing, and government efforts to support people who are chronically ill, elderly or with disabilities to live in their own homes, has led to the primary responsibility of care being undertaken by families. Through its social policies, the Australian government provides income and other types of support to informal caregivers. This article explores how Australian social policy and women's understanding of their roles impact on their access to welfare support. Qualitative research was conducted in Melbourne between February and June 2006. In-depth interviews were undertaken with eight Russian-speaking women involved in caregiving, purposively recruited through ethnic associations, and with four community service providers. Women based their expectations of the gendered and private nature of their role on the social policies in countries of their origin and, hence, did not attempt to access welfare support unless they were referred by health and welfare professionals. In addition, poor referral by professionals, influenced by past societal attitudes that caregiving is a gendered role, contributed to women's limited access to welfare benefits. Changes in the implementation of social policy are proposed to increase caregivers' access to welfare support and efficient utilisation of existing resources.

We find a series of nine absorption lines with a velocity of 0.24c from an ultra-fast outflow. For the first time, we are able to see extremely rapid variability of the UFO features, and can link this to the X-ray variability from the inner accretion disk. We find a clear flux dependence of the outflow features, suggesting that the wind is ionized by increasing X-ray emission.

In order to support advanced manufacturing, Sandia has acquired the capability to produce plastic prototypes using stereolithography. Currently, these prototypes are used mainly to verify part geometry and ``fit and form`` checks. This project investigates methods for rapidly testing these plastic prototypes, and inferring from prototype test data actual metal part performance and behavior. Performances examined include static load/stress response, and structural dynamic (modal) and vibration behavior. The integration of advanced non-contacting measurement techniques including scanning laser velocimetry, laser holography, and thermoelasticity into testing of these prototypes is described. Photoelastic properties of the epoxy prototypes to reveal full field stress/strain fields are also explored.

The development of computational tools to enable testing and analysis of high-throughput-sequencing data is essential to modern genomics research. However, although multiple frameworks have been developed to facilitate access to these tools, comparatively little effort has been made at implementing low-level programming libraries to increase the speed and ease of their development. We propose NGS++, a programming library in C++11 specialized in manipulating both next-generation sequencing (NGS) datasets and genomic information files. This library allows easy integration of new formats and rapid prototyping of new functionalities with a focus on the analysis of genomic regions and features. It offers a powerful, yet versatile and easily extensible interface to read, write and manipulate multiple genomic file formats. By standardizing the internal data structures and presenting a common interface to the data parser, NGS++ offers an effective framework for epigenomics tool development. NGS++ was written in C++ using the C++11 standard. It requires minimal efforts to build and is well-documented via a complete docXygen guide, online documentation and tutorials. Source code, tests, code examples and documentation are available via the website at http://www.ngsplusplus.ca and the github repository at https://github.com/NGS-lib/NGSplusplus. email@example.com or firstname.lastname@example.org.
Full Text Available The development of “open” academic content has been strongly embraced and promoted by many advocates, analysts, stakeholders, and reformers in the sector of higher education and academic publishing. The two most well-known developments are open access scholarly publishing and Massive Online Open Courses (MOOCs, each of which are connected to disruptive innovations enabled by new technologies. Support for these new modes of exchanging knowledge is linked to the expectation that they will promote a number of public interest benefits, including widening the impact, productivity, and format of academic work; reforming higher education and scholarly publishing markets; and relieving some of the cost pressures in academia. This article examines the rapid emergence of policy initiatives in the United Kingdom and the United States to promote open content and to bring about a new relationship between the market and the academic commons. In doing so, I examine controversial forms of academic unbundling such as open access megajournals and MOOCs and place each in the context of the heightened emphasis on productivity and impact in new regulatory regimes in the area of higher education.

Full Text Available Nearly thirty percent of all newly synthesized polypeptides are targeted for rapid proteasome-mediated degradation. These rapidly degraded polypeptides (RDPs are a source of antigenic substrates for the MHC class I presentation pathway, allowing for immunosurveillance of newly synthesized proteins by cytotoxic T lymphocytes. Despite the recognized role of RDPs in MHC I presentation, it remains unclear what molecular characteristics distinguish RDPs from their more stable counterparts. It has been proposed that premature translational termination products may constitute a form of RDP; indeed, in prokaryotes translational drop-off products are normal by-products of protein synthesis and are subsequently rapidly degraded. To study the cellular fate of premature termination products, we used the antibiotic puromycin as a means to experimentally manipulate prematurely terminated polypeptide production in human cells. At low concentrations, puromycin enhanced flux into rapidly degraded polypeptide pools, with small polypeptides being markedly more labile then high molecular weight puromycin adducts. Immunoprecipitation experiments using anti-puromycin antisera demonstrated that the majority of peptidyl-puromycins are rapidly degraded in a proteasome-dependent manner. Low concentrations of puromycin increased the recovery of cell surface MHC I-peptide complexes, indicating that prematurely terminated polypeptides can be processed for presentation via the MHC I pathway. In the continued presence of puromycin, however, MHC I export to the cell surface was inhibited, coincident with the accumulation of polyubiquitinated proteins. The time- and dose-dependent effects of puromycin suggest that the pool of peptidyl-puromycin adducts differ in their targeting to various proteolytic pathways that, in turn, differ in the efficiency with which they access the MHC I presentation machinery. These studies highlight the diversity of cellular proteolytic pathways

We present a novel high-order access dependencies based model for efficient pathline computation in unsteady flow visualization. By taking longer access sequences into account to model more sophisticated data access patterns in particle tracing, our method greatly improves the accuracy and reliability in data access prediction. In our work, high-order access dependencies are calculated by tracing uniformly-seeded pathlines in both forward and backward directions in a preprocessing stage. The effectiveness of our proposed approach is demonstrated through a parallel particle tracing framework with high-order data prefetching. Results show that our method achieves higher data locality and hence improves the efficiency of pathline computation.

The mineralocorticoid receptor (MR) is a ligand-dependent transcription factor that physiologically regulates water-electrolyte homeostasis and controls blood pressure. The MR can also elicit inflammatory and remodeling processes in the cardiovascular system and the kidneys, which require the presence of additional pathological factors like for example nitrosative stress. However, the underlying molecular mechanism(s) for pathophysiological MR effects remain(s) elusive. The inactive MR is located in the cytosol associated with chaperone molecules including HSP90. After ligand binding, the MR monomer rapidly translocates into the nucleus while still being associated to HSP90 and after dissociation from HSP90 binds to hormone-response-elements called glucocorticoid response elements (GREs) as a dimer. There are indications that rapid MR trafficking is modulated in the presence of high salt, oxidative or nitrosative stress, hypothetically by induction or posttranslational modifications. Additionally, glucocorticoids and the enzyme 11beta hydroxysteroid dehydrogenase may also influence MR activation. Because MR trafficking and its modulation by micro-milieu factors influence MR cellular localization, it is not only relevant for genomic but also for nongenomic MR effects.

US industry is fighting to maintain its competitive edge in the global market place. Today markets fluctuate rapidly. Companies, to survive, have to be able to respond with quick-to-market, improved, high quality, cost efficient products. The way products are developed and brought to market can be improved and made more efficient through the proper incorporation of emerging technologies. The RRM project was established to leverage the expertise and resources of US private industries and federal agencies to develop, integrate, and deploy new technologies that meet critical needs for effective product realization. The RRM program addressed a needed change in the US Manufacturing infrastructure that will ensure US competitiveness in world market typified by mass customization. This project provided the effort needed to define, develop and establish a customizable infrastructure for rapid response product development design and manufacturing. A major project achievement was the development of a broad-based framework for automating and integrating the product and process design and manufacturing activities involved with machined parts. This was accomplished by coordinating and extending the application of feature-based product modeling, knowledge-based systems, integrated data management, and direct manufacturing technologies in a cooperative integrated computing environment. Key technological advancements include a product model that integrates product and process data in a consistent, minimally redundant manner, an advanced computer-aided engineering environment, knowledge-based software aids for design and process planning, and new production technologies to make products directly from design application software.
Full Text Available Abstract Open Access publishing is a valuable resource for the synthesis and distribution of essential health care information. This article discusses the potential benefits of Open Access, specifically in terms of Low and Middle Income (LAMI countries in which there is currently a lack of informed health care providers – mainly a consequence of poor availability to information. We propose that without copyright restrictions, Open Access facilitates distribution of the most relevant research and health care information. Furthermore, we suggest that the technology and infrastructure that has been put in place for Open Access could be used to publish download-able manuals, guides or basic handbooks created by healthcare providers in LAMI countries.

Call for Papers: Optical Access Networks Guest Editors Jun Zheng, University of Ottawa Nirwan Ansari, New Jersey Institute of Technology Submission Deadline: 1 June 2005 h2>Backgroundh2> With the wide deployment of fiber-optic technology over the past two decades, we have witnessed a tremendous growth of bandwidth capacity in the backbone networks of today's telecommunications infrastructure. However, access networks, which cover the "last-mile" areas and serve numerous residential and small business users, have not been scaled up commensurately. The local subscriber lines for telephone and cable television are still using twisted pairs and coaxial cables. Most residential connections to the Internet are still through dial-up modems operating at a low speed on twisted pairs. As the demand for access bandwidth increases with emerging high-bandwidth applications, such as distance learning, high-definition television (HDTV), and video on demand (VoD), the last-mile access networks have become a bandwidth bottleneck in today's telecommunications infrastructure. To ease this bottleneck, it is imperative to provide sufficient bandwidth capacity in the access networks to open the bottleneck and thus present more opportunities for the provisioning of multiservices. Optical access solutions promise huge bandwidth to service providers and low-cost high-bandwidth services to end users and are therefore widely considered the technology of choice for next-generation access networks. To realize the vision of optical access networks, however, many key issues still need to be addressed, such as network architectures, signaling protocols, and implementation standards. The major challenges lie in the fact that an optical solution must be not only robust, scalable, and flexible, but also implemented at a low cost comparable to that of existing access solutions in order to increase the economic viability of many potential high-bandwidth applications. In recent years, optical access

Objectives Rapid disposition protocols are increasingly being considered for implementation in emergency departments (EDs). Among patients presenting to an adult tertiary referral hospital, this study aimed to compare prediction accuracy of a rapid disposition decision at the conclusion of history and examination, compared with disposition following standard assessment. Methods Prospective observational data were collected for 1 month between October and November 2012. Emergency clinicians (including physicians, registrars, hospital medical officers, interns and nurse practitioners) filled out a questionnaire within 5min of obtaining a history and clinical examination for eligible patients. Predicted patient disposition (representing 'rapid disposition') was compared with final disposition (determined by 'standard assessment'). Results There were 301 patient episodes included in the study. Predicted disposition was correct in 249 (82.7%, 95% confidence interval (CI) 78.0-86.8) cases. Accuracy of predicting discharge to home appeared highest among emergency physicians at 95.8% (95% CI 78.9-99.9). Overall accuracy at predicting admission was 79.7% (95% CI 67.2-89.0). The remaining 20.3% (95% CI 11.0-32.8) were not admitted following standard assessment. Conclusion Rapid disposition by ED clinicians can predict patient destination accurately but was associated with a potential increase in admission rates. Any model of care using rapid disposition decision making should involve establishment of inpatient systems for further assessment, and a culture of timely inpatient team transfer of patients to the most appropriate treating team for ongoing patient management. What is known about the topic? In response to the National Emergency Access Targets, there has been widespread adoption of rapid-disposition-themed care models across Australia. Although there is emerging data that clinicians can predict disposition accurately, this data is currently limited. What does this

Introduction Accessibility and assistive products and technologies are needed to ensure the rights of persons with disabilities and older persons. Many developments have been implemented in laws, standards, markets and from the consumers perspective, at international, European and national levels. The real issue is that not all the potential users benefit from the use of assistive products or accessible measures. Discussion Innovative methods are needed to allow all potential users to have real advantage of assistive technologies and accessible and design for all facilities. Best practices will be presented and existing gaps and recommendations will be discussed. Cost-benefits aspects will also be presented. Conclusion In order to get advantages from opportunities of globalization, hard work and responsibilities of all stakeholders are needed, so that assistive products and accessibility reach a whole range of situations and environments and contribute to ensure quality of life in a society for all.

An accessible urban environment is crucial for a healthy, dynamic and economically vibrant city. It will not come as a surprise to anyone to learn that accessibility is a growing problem for many cities. In recent decades, the number of inhabitants has risen considerably, while economic activity has also increased. It is only logical that the number of travel journeys has therefore also grown strongly. In many places, this has been to the detriment of the living environment, with congestion f...

Accessible Geoscience is a developing field of pedagogic research aimed at widening participation in Geography, Earth and Environmental Science (GEES) subjects. These subjects are often less commonly associated with disabilities, ethnic minorities, low income socio-economic groups and females. While advancements and improvements have been made in the inclusivity of these subject areas in recent years, access and participation of disabled students remains low. While universities are legally obligated to provide reasonable adjustments to ensure accessibility, the assumed incompatibility of GEES subjects and disability often deters students from applying to study these courses at a university level. Instead of making reasonable adjustments if and when they are needed, universities should be aiming to develop teaching materials, spaces and opportunities which are accessible to all, which in turn will allow all groups to participate in the GEES subjects. With this in mind, the Swansea Geography Department wish to enhance the accessibility of our undergraduate degree by developing digital field work opportunities. In the first instance, we intend to digitise three afternoon excursions which are run as part of a 1st year undergraduate module. Each of the field trips will be digitized into English- and Welsh-medium formats. In addition, each field trip will be digitized into British Sign Language (BSL) to allow for accessibility for D/deaf and hard of hearing students. Subtitles will also be made available in each version. While the main focus of this work is to provide accessible fieldwork opportunities for students with disabilities, this work also has additional benefits. Students within the Geography Department will be able to revisit the field trips, to revise and complete associated coursework. The use of digitized field work should not replace opportunities for real field work, but its use by the full cohort of students will begin to "normalize" accessible field

Introduction Increasing access to HIV-related care and treatment for children aged 0-18 years in resource-limited settings is an urgent global priority. In 2011-2012 the percentage increase in children accessing antiretroviral therapy was approximately half that of adults (11 vs. 21 %). We propose a model for increasing access to, and retention in, paediatric HIV care and treatment in resource-limited settings. Methods Following a rapid appraisal of recent literature seven main challenges in paediatric HIV-related care and treatment were identified: (1) lack of regular, integrated, ongoing HIV-related diagnosis; (2) weak facility-based systems for tracking and retention in care; (3) interrupted availability of dried blood spot cards (expiration/stock outs); (4) poor quality control of rapid HIV testing; (5) supply-related gaps at health facility-laboratory interface; (6) poor uptake of HIV testing, possibly relating to a fatalistic belief about HIV infection; (7) community-associated reasons e.g. non-disclosure and weak systems for social support, resulting in poor retention in care. Results To increase sustained access to paediatric HIV-related care and treatment, regular updating of Policies, review of inter-sectoral Plans (at facility and community levels) and evaluation of Programme implementation and impact (at national, subnational, facility and community levels) are non-negotiable critical elements. Additionally we recommend the intensified implementation of seven main interventions: (1) update or refresher messaging for health care staff and simple messaging for key staff at early childhood development centres and schools; (2) contact tracing, disclosure and retention monitoring; (3) paying particular attention to infant dried blood spot (DBS) stock control; (4) regular quality assurance of rapid HIV testing procedures; (5) workshops/meetings/dialogues between health facilities and laboratories to resolve transport-related gaps and to facilitate return of

The use of rapid response teams is a relatively new approach for decreasing or eliminating codes in acute care hospitals. Based on the principles of a code team for cardiac and/or respiratory arrest in non-critical care units, the rapid response teams have specially trained nursing, respiratory, and medical personnel to respond to calls from general care units to assess and manage decompensating or rapidly changing patients before their conditions escalate to a full code situation. This article describes the processes used to develop a rapid response team, clinical indicators for triggering a rapid response team call, topics addressed in an educational program for the rapid response team members, and methods for evaluating effectiveness of the rapid response team.
Full Text Available BACKGROUND: With the rapid development of urbanization, pregnant population is growing rapidly in Shenzhen, and it has been a difficulty to serve more and more pregnant women and reduce spatial access disparities to maternity units (MUs. Understanding of the current status of accessibility to MUs is valuable for supporting the rational allocation of MUs in the future. METHODS: Based on pregnant population data and MUs data, this study uses a two-step floating catchment area (2SFCA method based on Geographic Information System (GIS to analyze the current spatial accessibility to MUs, and then make a comparison between that to public MUs and private MUs. RESULTS: Our analysis of the accessibility to all MUs within a distance of 20 km shows that the accessibilities of the areas alongside the traditional border management line are acceptable, meanwhile highlights some critical areas, such as the west part of Nanshan district and the vast east part of Longgang district. The comparison between spatial accessibility to public MUs and private MUs shows statistically significant difference. DISCUSSION: Results of this study suggest a great effort should be made to improve the equity of spatial accessibility to MUs in Shenzhen. For policy-making, strategy for the siting and allocation of future MUs, no matter public or private, should guarantee the greatest spatial accessibility for every pregnant woman.

South Korea's export-oriented development strategy has achieved a remarkable growth record, but it has also brought 2 different problems: 1) since the country's exports accounted for about 1% of total world export volume, the 1st world has become fearful about Korea's aggressive export drive; and 2) the fact that exports account for over 30% of its total gross national product (GNP) exposes the vulnerability of South Korea's economy itself. South Korea continues to be a poor nation, although it is rated as 1 of the most rapidly growing middle income economies. A World Bank 1978 report shows Korea to be 28th of 58 middle income countries in terms of per capita GNP in 1976. Of 11 newly industrializing countries (NIC), 5 in the European continent are more advanced than the others. A recent emphasis on the basic human needs approach has tended to downgrade the concept of GNP. Korea has only an abundant labor force and is without any natural resources. Consequently, Korea utilized an export-oriented development strategy. Oil requirements are met with imports, and almost all raw materials to be processed into exportable products must be imported. To pay import bills Korea must export and earn foreign exchange. It must be emphasized that foreign trade must always be 2-way traffic. In order to export more to middle income countries like Korea, the countries of the 1st world need to ease their protectionist measures against imports from developing countries.

Method and system for rapid and accurate determination of each of a sequence of unknown polymer components, such as nucleic acid components. A self-assembling monolayer of a selected substance is optionally provided on an interior surface of a pipette tip, and the interior surface is immersed in a selected liquid. A selected electrical field is impressed in a longitudinal direction, or in a transverse direction, in the tip region, a polymer sequence is passed through the tip region, and a change in an electrical current signal is measured as each polymer component passes through the tip region. Each of the measured changes in electrical current signals is compared with a database of reference electrical change signals, with each reference signal corresponding to an identified polymer component, to identify the unknown polymer component with a reference polymer component. The nanopore preferably has a pore inner diameter of no more than about 40 nm and is prepared by heating and pulling a very small section of a glass tubing.

Stellar oscillations give seismic information on the internal properties of stars. Red giants are targets of interest since they present mixed modes, wich behave as pressure modes in the convective envelope and as gravity modes in the radiative core. Mixed modes thus directly probe red giant cores, and allow in particular the study of their mean core rotation. The high-quality data obtained by CoRoT and Kepler satellites represent an unprecedented perspective to obtain thousands of measurements of red giant core rotation, in order to improve our understanding of stellar physics in deep stellar interiors. We developed an automated method to obtain such core rotation measurements and validated it for stars on the red giant branch. In this work, we particularly focus on the specific application of this method to red giants having a rapid core rotation. They show complex spectra where it is tricky to disentangle rotational splittings from mixed-mode period spacings. We demonstrate that the method based on the identification of mode crossings is precise and efficient. The determination of the mean core rotation directly derives from the precise measurement of the asymptotic period spacing ΔΠ1 and of the frequency at which the crossing of the rotational components is observed.
Rocketdyne Propulsion and Power, an operating location of Boeing in Canoga Park, California is under contract with NASA's Marshall Space Flight Center (MSFC) in Huntsville, Alabama for design, development, production, and mission support of Space Shuttle Main Engines (SSMEs). The contract was restructured in 1996 to emphasize a mission contracting environment under which Rocketdyne supports the Space Transportation System launch manifest of seven flights a year without the need for a detailed list of contract deliverables such as nozzles, turbopumps, and combustion devices. This contract structure is in line with the overall Space Shuttle program goals established by the NASA to fly safely, meet the flight manifest, and reduce cost. Rocketdyne's Contracts, Pricing, and Estimating team has worked for the past several years with representatives from MSFC, the local Defense Contract Management Command, and the DCAA to improve the quality of cost proposals to MSFC for contract changes on the SSME. The contract changes on the program result primarily from engineering change proposals for product enhancements to improve safety, maintainability, or operability in the space environment. This continuous improvement team effort has been successful in improving proposal quality, reducing cycle time, and reducing cost.

This brief focuses on medium access control (MAC) in vehicular ad hoc networks (VANETs), and presents VeMAC, a novel MAC scheme based on distributed time division multiple access (TDMA) for VANETs. The performance of VeMAC is evaluated via mathematical analysis and computer simulations in comparison with other existing MAC protocols, including the IEEE 802.11p standard. This brief aims at proposing TDMA as a suitable MAC scheme for VANETs, which can support the quality-of-service requirements of high priority VANET applications.
Full Text Available The importance of accessibility to digital resources is now widely acknowledged. The W3C WAI has played a significant role in promoting the importance of accessibility and developing a framework for accessible Web resources. The accessibility of e-learning provides additional challenges that may not be faced when providing access to other Web resources. The authors argue that there is a need for a more sophisticated model for addressing e-learning accessibility which takes into account the usability of e-learning, pedagogic issues and student learning styles in addition to technical and resource issues. The authors expand on these issues and propose a holistic model for the development of accessible e-learning resources.

A challenge for any consumer of National Oceanic and Atmospheric Administration (NOAA) environmental data archives is that the disparate nature of these archives makes it difficult for consumers to access data in a unified manner. If it were possible for consumers to have seamless access to these archives, they would be able to better utilize the data and thus maximize the return on investment for NOAA’s archival program. When unified data access is coupled with sophisticated data querying and discovery techniques, it will be possible to provide consumers with access to richer data sets and services that extend the use of key NOAA data. Theoretically, there are two ways that unified archive access may be achieved. The first approach is to develop a single archive or archiving standard that would replace the current NOAA archives. However, the development of such an archive would pose significant technical and administrative challenges. The second approach is to develop a middleware application that would provide seamless access to all existing archives, in effect allowing each archive to exist “as is” but providing a translation service for the consumer. This approach is deemed more feasible from an administrative and technical standpoint; however, it still presents unique technical challenges due to the disparate architectures that exist across NOAA archives. NOAA has begun developing the NEAAT. The purpose of NEAAT is to provide a middleware and a simple standardized API between NOAA archives and data consumers. It is important to note that NEAAT serves two main purposes: 1) To provide a single application programming interface (API) that enables designated consumers to write their own custom applications capable of searching and acquiring data seamlessly from multiple NOAA archives. 2) To allow archive managers to expose their data to consumers in conjunction with other NOAA resources without modifying their archiving systems or way of presenting data

This article argues that existing studies on cultural capital and educational success fail to distinguish the different channels through which cultural capital promotes educational success. Following Bourdieu, the article proposes that for cultural capital to promote educational success three...... conditions must hold: (1. parents must possess cultural capital, (2. they must transfer their cultural capital to children, and (3. children must absorb cultural capital and convert it into educational success. This research develops an empirical model that analyzes the significance of the three effects...... with respect to Danish children's choice of secondary education. Denmark is well-suited for this study because access to secondary education is particularly meritocratic. The empirical analysis shows that all three channels through which cultural capital affects educational success are important....

Almost all of the elementary steps in a biochemical reaction scheme are either unimolecular or bimolecular processes that frequently occur on sub-second, often sub-millisecond, time scales. The traditional approach in kinetic studies is to mix two or more reagents and monitor the changes in concentrations with time. Conventional spectrophotometers cannot generally be used to study reactions that are complete within less than about 20 s, as it takes that amount of time to manually mix the reagents and activate the instrument. Rapid mixing techniques, which generally achieve mixing in less than 2 ms, overcome this limitation. This chapter is concerned with the use of these techniques in the study of reactions which reach equilibrium; the application of these methods to the study of enzyme kinetics is described in several excellent texts (Cornish-Bowden, Fundamentals of enzyme kinetics. Portland Press, 1995; Gutfreund, Kinetics for the life sciences. Receptors, transmitters and catalysis. Cambridge University Press, 1995).There are various ways to monitor changes in concentration of reactants, intermediates and products after mixing, but the most common way is to use changes in optical signals (absorbance or fluorescence) which often accompany reactions. Although absorbance can sometimes be used, fluorescence is often preferred because of its greater sensitivity, particularly in monitoring conformational changes. Such methods are continuous with good time resolution but they seldom permit the direct determination of the concentrations of individual species. Alternatively, samples may be taken from the reaction volume, mixed with a chemical quenching agent to stop the reaction, and their contents assessed by techniques such as HPLC. These methods can directly determine the concentrations of different species, but are discontinuous and have a limited time resolution.
Full Text Available Ownership of intellectual property rights for a large proportion of the scholarly record is held by publishers, so a majority of journal articles are behind paywalls and unavailable to most people. As a result some readers are encouraged to use pirate websites such as Sci-Hub to access them, a practice that is alternately regarded as criminal and unethical or as a justified act of civil disobedience. This article considers both the efficacy and ethics of piracy, placing ‘guerrilla open access’ within a longer history of piracy and access to knowledge. By doing so, it is shown that piracy is an inevitable part of the intellectual landscape that can render the current intellectual property regime irrelevant. If we wish to actively construct a true scholarly commons, open access emerges as a contender for moving beyond proprietary forms of commodifying scholarly knowledge towards the creation of an open scholarly communication system that is fit for purpose.

OBJECTIVE To determine whether access to health information via in-home Internet technology can positively influence empowerment among residents of a low-income urban community. DESIGN In-home Internet access and training were provided to volunteers, who, along with a comparison group, were interviewed prior to and 1 year after initiation of the program. Community-based participatory research methods were used to design and implement the intervention. SETTING A 57-block area on the West Side of Chicago. PATIENTS/PARTICIPANTS Twenty-five community residents completed all phases of the technology intervention. Thirty-five randomly selected neighbors of these residents served as the comparison group. INTERVENTIONS Members of the intervention group received Internet access via WebTV, training, technical support, and access to a community specific health-oriented web page during the course of the study. MEASUREMENTS AND MAIN RESULTS Intervention group members were similar to comparison group members in terms of empowerment at baseline. After receiving Internet access and training, empowerment related to health decision-making improved significantly in the intervention group. Similar changes did not occur in the comparison group. Affinity for and appreciation of information technology also increased in the intervention group but not in the comparison group. As a result, differences in attitudes toward technology increased between the 2 groups over time. CONCLUSIONS Using community-based participatory research methods, we found that Internet access to community-specific and general health information can lead to increased empowerment and appreciation of information technology. These benefits accrued among the intervention group but not among a random group of their neighbors. PMID:12848835

Full Text Available Technology entrepreneurs continuously search for tools to accelerate the internationalization of their startups. For the purpose of internationalizing rapidly from inception, we propose that technology startups use crowdsourcing to internalize the tacit knowledge embodied in members of a crowd distributed across various geographies. For example, a technology startup can outsource to a large crowd the definition of a customer problem that occurs across various geographies, the development of the best solution to the problem, and the identification of attractive business expansion opportunities. In this article, we analyze how three small firms use crowdsourcing, discuss the benefits of crowdsourcing, and offer six recommendations to technology entrepreneurs interested in using crowdsourcing to rapidly internationalize their startups from inception.

There are strong pragmatic and moral reasons for receiving societies to address access to healthcare for migrants. Receiving societies have a pragmatic interest in sustaining migrants' health to facilitate integration; they also have a moral obligation to ensure migrants' access to healthcare according to international human rights principles. The intention of this thesis is to increase the understanding of migrants' access to healthcare by exploring two study aims: 1) Are there differences in migrants' access to healthcare compared to that of non-migrants? (substudy I and II); and 2) Why are there possible differences in migrants' access to healthcare compared to that of non-migrants? (substudy III and IV). The thesis builds on different methodological approaches using both register-based retrospective cohort design, cross-sectional design and survey methods. Two different measures of access were used to explore differences: 1) cancer stage at diagnosis as a clinical outcome and 2) emergency room (ER) contacts as a utilisation measure. Both informal and formal barriers to access were studied to explore why possible differences existed including: 1) motivation for using ER; and 2) asylum seekers' healthcare entitlements. Different definitions of migration and ethnicity were investigated including: country of birth and residence status. Substudy I showed a tendency towards more advanced stage at diagnosis or unknown stage among most subgroups of migrant women with a history of cancer compared to non-migrant women. Sub-study II found that some migrants (those born in Somalia, Turkey and Ex-Yugoslavia) use ER services more frequently than do non-migrants whereas others have the same or lower utilisation levels. As a consequence, substudy III was undertaken, which documented that more migrant within all subgroups had considered contacting a primary caregiver before visiting the ER compared to non-migrants, but that migrants experienced communication problems herein
Full Text Available Due to the progress of network technology, we can access some information through remote servers, and we also can save and access lots of personal data in remote servers. Therefore, to protect these data and resist unauthorized access is an important issue. Some researchers proposed authentication scheme, but there still exist some security weaknesses. This article is based on the concept of HDFS (Hadoop Distributed File System, and offers a robust authentication scheme. The proposed scheme achieves mutual authentication, prevents re-play attack, solves asynchronous issue, and prevents offline password guessing attack.
A field-deployable, battery-powered Rapid Active Sampling Package (RASP), originally designed for sampling strong materials during lunar and planetary missions, shows strong utility for terrestrial geological use. The technology is proving to be simple and effective for sampling and processing materials of strength. Although this originally was intended for planetary and lunar applications, the RASP is very useful as a powered hand tool for geologists and the mining industry to quickly sample and process rocks in the field on Earth. The RASP allows geologists to surgically acquire samples of rock for later laboratory analysis. This tool, roughly the size of a wrench, allows the user to cut away swaths of weathering rinds, revealing pristine rock surfaces for observation and subsequent sampling with the same tool. RASPing deeper (.3.5 cm) exposes single rock strata in-situ. Where a geologist fs hammer can only expose unweathered layers of rock, the RASP can do the same, and then has the added ability to capture and process samples into powder with particle sizes less than 150 microns, making it easier for XRD/XRF (x-ray diffraction/x-ray fluorescence). The tool uses a rotating rasp bit (or two counter-rotating bits) that resides inside or above the catch container. The container has an open slot to allow the bit to extend outside the container and to allow cuttings to enter and be caught. When the slot and rasp bit are in contact with a substrate, the bit is plunged into it in a matter of seconds to reach pristine rock. A user in the field may sample a rock multiple times at multiple depths in minutes, instead of having to cut out huge, heavy rock samples for transport back to a lab for analysis. Because of the speed and accuracy of the RASP, hundreds of samples can be taken in one day. RASP-acquired samples are small and easily carried. A user can characterize more area in less time than by using conventional methods. The field-deployable RASP used a Ni

Internet of Things (IoT) requires novel solutions to facilitate autonomous, though controlled, resource access. Access policies have to facilitate interactions between heterogeneous entities (devices and humans). Here, we focus our attention on access control in eHealth. We propose an approach based on enriching policies, based on well-known and widely-used eXtensible Access Control Markup Language, with semantics. In the paper we describe an implementation of a Policy Information Point integrated with the HL7 Security and Privacy Ontology.

The transition to open access (OA) is being driven by funders, libraries, researchers and publishers around the world, and is having an impact on us all. It is inevitable that different countries, organisations and disciplines are moving at different rates towards an OA model, and it is this that we will focus on in this session. Drawing on experiences from across Europe and the Middle East we will provide perspectives from both a global publisher and institutions based in the region. Taylor & Francis take a flexible, evidence-based approach to open access, providing a choice of publication routes for our authors, and a choice of agreements for our library customers. Carolyn will outline some of the open access developments, opportunities and challenges at Taylor & Francis. The library plays a critical role in facilitating open access for their researchers, from managing a repository to providing support and information on the OA publication process to their authors. Janis Tyhurst and Dr Imad Bachir will each give an overview of how this is being managed by their institution. There will be an opportunity for questions and discussion with the panel.

Full Text Available Big data technologies have seen tremendous growth in recent years. They are widely used in both industry and academia. In spite of such exponential growth, these technologies lack adequate measures to protect data from misuse/abuse. Corporations that collect data from multiple sources are at risk of liabilities due to the exposure of sensitive information. In the current implementation of Hadoop, only file-level access control is feasible. Providing users with the ability to access data based on the attributes in a dataset or the user’s role is complicated because of the sheer volume and multiple formats (structured, unstructured and semi-structured of data. In this paper, we propose an access control framework, which enforces access control policies dynamically based on the sensitivity of the data. This framework enforces access control policies by harnessing the data context, usage patterns and information sensitivity. Information sensitivity changes over time with the addition and removal of datasets, which can lead to modifications in access control decisions. The proposed framework accommodates these changes. The proposed framework is automated to a large extent as the data itself determines the sensitivity with minimal user intervention. Our experimental results show that the proposed framework is capable of enforcing access control policies on non-multimedia datasets with minimal overhead.

For a comprehensive understanding of the environment, the brain must constantly decide whether the incoming information originates from the same source and needs to be integrated into a coherent percept. This integration process is believed to be mediated by temporal integration windows. If presented with temporally asynchronous stimuli for a few minutes, the brain adapts to this new temporal relation by recalibrating the temporal integration windows. Such recalibration can occur even more rapidly after exposure to just a single trial of asynchronous stimulation. While rapid recalibration has been demonstrated for audio-visual stimuli, evidence for rapid recalibration of visuo-tactile stimuli is lacking. Here, we investigated rapid recalibration in the visuo-tactile domain. Subjects received visual and tactile stimuli with different stimulus onset asynchronies (SOA) and were asked to report whether the visuo-tactile stimuli were presented simultaneously. Our results demonstrate visuo-tactile rapid recalibration by revealing that subjects' simultaneity reports were modulated by the temporal order of stimulation in the preceding trial. This rapid recalibration effect, however, was only significant if the SOA in the preceding trial was smaller than 100 ms, while rapid recalibration could not be demonstrated for SOAs larger than 100 ms. Since rapid recalibration in the audio-visual domain has been demonstrated for SOAs larger than 100 ms, we propose that visuo-tactile recalibration works at shorter SOAs, and thus faster time scales than audio-visual rapid recalibration.

Current scientific evidence is that radiation at low levels is not harmful, but beneficial. This is borne out by both radiobiology and epidemiology. The ICRP 26 recommended limits of 50 mSv and 5 mSv per annum are comparable with the average natural background levels in Iran and Norway, respectively, and levels five times higher than that quoted for Iran are to be found in some populated parts of this world. The new limits proposed for ionising radiation are generated by comparison to existing recommended limits for essential minerals. There is a range of acceptable exposures to radiation, just as there is for minerals. The replacement for the ICRP 60 recommendations (20 mSv and 1 mSv for radiation workers and public respectively) should be higher limits of 200 mSv and 50 mSv. There should also be minimum recommended annual levels of 10 mSv, for both radiation workers and the public. The consequences of not proposing this change are continuing huge negative impacts to society. In cancer therapy, even the older guidelines caused unnecessary expense and delays. The cost to Canada is astronomical, when one considers the effect of the existing limits on the use of nuclear power, and the resulting use of hydrocarbons and the consequent increase in acid rain, etc. Of course, the same thing can be said of the entire world limited funds are diverted from areas where they would be better applied, and alternative solutions to societal needs are implemented, solutions which increase pollution and cause injury and death. It is time to reverse the current, expensive trend into misapplied ALARA, based on the paranoia about all things nuclear, which has developed since the linear no-threshold hypothesis was first proposed.propose the transition to a realistic and balanced approach to ionising radiation.

Since the ICFA decision on the choice of technology, a world-wide collaboration on the design of the ILC has rapidly progressed. The formation of the GDE will accelerate the work towards a final design. An important technical challenge is obviously the high gradient acceleration but what is similarly challenging is the collision of extremely small beams of a few nanometer size. The latter challenge has three distinct issues: creating small emittance beams, preserving the emittance during acceleration and transport, and focusing the beams to nanometers. Most studies have been done using computer simulations but many issues still remain that require experimental verification. KEK-ATF was built to create small emittance beams, and succeeded in obtaining an emittance that almost satisfies the ILC requirements. In this proposal we present a project, ATF2, which addresses the third issue, namely the focusing of the beam into nanometer spot.ybr> In the longer term, the ATF2 project would also provide invaluable inpu...

Sector of electric lighting offers great opportunities for increasing energy efficiency due to the rapid development of LED technology. Nowadays LED lighting is still expensive and have relatively little application in the domain of electric lighting. However, it is anticipated that LED products would soon greatly transform the electric lighting market. In recent years, LED technology has significantly improved, and constantly evolving. It is expected that advanced and future LED bulbs / lamps to be getting cheaper and with a better technical characteristics and that they will soon be dominant on the lighting market. Serbia must prepare for the LED future, creating appropriate legislation and promotion of appropriate incentive measures.

Fixed broadband network deployments are moving inexorably to the use of Next Generation Access (NGA) technologies and architectures. These NGA deployments involve building fiber infrastructure increasingly closer to the customer in order to increase the proportion of fiber on the customer's access connection (Fibre-To-The-Home/Building/Door/Cabinet… i.e. FTTx). This increases the speed of services that can be sold and will be increasingly required to meet the demands of new generations of video services as we evolve from HDTV to "Ultra-HD TV" with 4k and 8k lines of video resolution. However, building fiber access networks is a costly endeavor. It requires significant capital in order to cover any significant geographic coverage. Hence many companies are forming partnerships and joint-ventures in order to share the NGA network construction costs. One form of such a partnership involves two companies agreeing to each build to cover a certain geographic area and then "cross-selling" NGA products to each other in order to access customers within their partner's footprint (NGA coverage area). This is tantamount to a bi-lateral wholesale partnership. The concept of Fixed Access Network Sharing (FANS) is to address the possibility of sharing infrastructure with a high degree of flexibility for all network operators involved. By providing greater configuration control over the NGA network infrastructure, the service provider has a greater ability to define the network and hence to define their product capabilities at the active layer. This gives the service provider partners greater product development autonomy plus the ability to differentiate from each other at the active network layer.
Remote Memory Access (RMA) programming enables direct access to low-level hardware features to achieve high performance for distributed-memory programs. However, the design of RMA programming schemes focuses on the memory access and less on the synchronization. For example, in contemporary RMA programming systems, the widely used producer-consumer pattern can only be implemented inefficiently, incurring in an overhead of an additional round-trip message. We propose Notified Access, a scheme where the target process of an access can receive a completion notification. This scheme enables direct and efficient synchronization with a minimum number of messages. We implement our scheme in an open source MPI-3 RMA library and demonstrate lower overheads (two cache misses) than other point-to-point synchronization mechanisms for each notification. We also evaluate our implementation on three real-world benchmarks, a stencil computation, a tree computation, and a Colicky factorization implemented with tasks. Our scheme always performs better than traditional message passing and other existing RMA synchronization schemes, providing up to 50% speedup on small messages. Our analysis shows that Notified Access is a valuable primitive for any RMA system. Furthermore, we provide guidance for the design of low-level network interfaces to support Notified Access efficiently.

Previous studies with Arabidopsis accessions revealed that biomass correlates negatively to dusk starch content and total protein, and positively to the maximum activities of enzymes in photosynthesis. We hypothesized that large accessions have lower ribosome abundance and lower rates of protein synthesis, and that this is compensated by lower rates of protein degradation. This would increase growth efficiency and allow more investment in photosynthetic machinery. We analysed ribosome abundance and polysome loading in 19 accessions, modelled the rates of protein synthesis and compared them with the observed rate of growth. Large accessions contained less ribosomes than small accessions, due mainly to cytosolic ribosome abundance falling at night in large accessions. The modelled rates of protein synthesis resembled those required for growth in large accessions, but were up to 30% in excess in small accessions. We then employed 13 CO2 pulse-chase labelling to measure the rates of protein synthesis and degradation in 13 accessions. Small accessions had a slightly higher rate of protein synthesis and much higher rates of protein degradation than large accessions. Protein turnover was negligible in large accessions but equivalent to up to 30% of synthesised protein day-1 in small accessions. We discuss to what extent the decrease in growth in small accessions can be quantitatively explained by known costs of protein turnover and what factors may lead to the altered diurnal dynamics and increase of ribosome abundance in small accessions, and propose that there is a trade-off between protein turnover and maximisation of growth rate. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd.
Full Text Available Discovering access patterns from web log data is a typical sequential pattern mining application, and a lot of access pattern mining algorithms have been proposed. In this paper, we propose an improved approach of Gap-BIDE algorithm to extract user access patterns from web log data. Compared with the previous Gap-BIDE algorithm, a process of getting a large event set is proposed in the provided algorithm; the proposed approach can find out the frequent events by discarding the infrequent events which do not occur continuously in an accessing time before generating candidate patterns. In the experiment, we compare the previous access pattern mining algorithm with the proposed one, which shows that our approach is very efficient in discovering access patterns in large database.

Innovative approaches are needed to address the needs of the 1.3 billion people lacking electricity, while simultaneously transitioning to a decarbonized energy system. With particular focus on the energy needs of the underserved, we present an analytic and conceptual framework that clarifies the heterogeneous continuum of centralized on-grid electricity, autonomous mini- or community grids, and distributed, individual energy services. A historical analysis shows that the present day is a unique moment in the history of electrification where decentralized energy networks are rapidly spreading, based on super-efficient end-use appliances and low-cost photovoltaics. We document how this evolution is supported by critical and widely available information technologies, particularly mobile phones and virtual financial services. These disruptive technology systems can rapidly increase access to basic electricity services and directly inform the emerging Sustainable Development Goals for quality of life, while simultaneously driving action towards low-carbon, Earth-sustaining, inclusive energy systems.
It may be possible to replace conventional actively cooled tokamak divertor plates with a set of rapidly moving, passively cooled divertor plates on rails. These plates would absorb the plasma heat flux with their thermal inertia for ~10-30 sec, and would then be removed from the vessel for processing. When outside the tokamak, these plates could be cooled, cleaned, recoated, inspected, and then returned to the vessel in an automated loop. This scheme could provide nearoptimal divertor surfaces at all times, and avoid the need to stop machine operation for repair of damaged or eroded plates. We describe various possible divertor plate designs and access geometries, and discuss an initial design for a movable and removable divertor module for NSTX-U.

Current access control mechanisms of the hospital information system can hardly identify the real access intention of system users. A relaxed access control increases the risk of compromise of patient privacy. To reduce unnecessary access of patient information by hospital staff, this paper proposes a Knowledge-Constrained Role-Based Access Control (KC-RBAC) model in which a variety of medical domain knowledge is considered in access control. Based on the proposed Purpose Tree and knowledge-involved algorithms, the model can dynamically define the boundary of access to the patient information according to the context, which helps protect patient privacy by controlling access. Compared with the Role-Based Access Control model, KC-RBAC can effectively protect patient information according to the results of the experiments.

A flexible very high frequency (VHF) stratosphere-troposphere (ST) radar configured for meteorological research is to be constructed near Urbana, Illinois. Measurement of small vertical velocities associated with synoptic-scale meteorology can be performed. A large Doppler microwave radar (CHILL) is located a few km from the site of the proposed ST radar. Since the microwave radar can measure the location and velocity of hydrometeors and the VHF ST radar can measure clear (or cloudy) air velocities, simultaneous observations by these two radars of stratiform or convective weather systems would provide valuable meteorological information.

Despite the availability of services, accessing health care remains a problem in the United States and other developed countries. Prenatal care has the potential to improve perinatal outcomes and decrease health disparities, yet many women struggle with access to care. Current theories addressing access to prenatal care focus on barriers, although such knowledge is minimally useful for clinicians. We propose a middle-range theory, the motivation-facilitation theory of prenatal care access, which condenses the prenatal care access process into 2 interacting components: motivation and facilitation. Maternal motivation is the mother's desire to begin and maintain care. Facilitation represents the goal of the clinic to create easy, open access to person-centered beneficial care. This simple model directs the focus of research and change to the interface of the woman and the clinic and encourages practice-level interventions that facilitate women entering and maintaining prenatal care. © 2013 by the American College of Nurse‐Midwives.

Full Text Available Although essentially not all therapies need drug intervention, drugs is still an important components in health sector, either in preventive, curative, rehabilitative or promotion efforts. Hence the access to drugs is a main problem, either in international or national scale even to the smallest unit. The problem on access to drugs is very complicated and cannot be separated especially from pharmacy management problems; moreover in general from the overall lack of policy development and effective of health policy, and also the implementation process. With the policy development and effective health policy, rational drug uses, sufficient health service budget so a country can overcome the health problems. Besides infrastructures, regulations, distribution and cultural influences; the main obstacles for drug access is drugs affordability if the price of drugs is an important part and determined by many factors, especially the drug status whether is still patent orgenerics that significantly decrease cost of health cares and enhance the drugs affordability. The determination of essential drug prices in developing countries should based on equity principal so that poor people pay cheaper and could afford the essential drugs. WHO predicts two third of world population can not afford the essential drugs in which in developing countries, some are because of in efficient budget allocation in consequence of drug distribution management, including incorrect selection and allocation and also irrational uses. In part these could be overcome by enhancing performances on the allocation pharmacy needs, including the management of information system, inventory management, stock management and the distribution.

Full Text Available Nature, one of the most prominent scientific journals dedicated one of its issues to recent changes in scientific publishing (Vol. 495, Issue 7442, 27 March 2013. Its editors stressed that words technology and revolution are closely related when it comes to scientific publishing. In addition, the transformation of research publishing is not as much a revolution than an attrition war in which all sides are buried. The most important change they refer to is the open-access model in which an author or an institution pays in advance for publishing a paper in a journal, and the paper is then available to users on the Internet free of charge.According to preliminary results of a survey conducted among 23 000 scientists by the publisher of Nature, 45% of them believes all papers should be published in open access, but at the same time 22% of them would not allow the use of papers for commercial purposes. Attitudes toward open access vary according to scientific disciplines, leading the editors to conclude the revolution still does not suit everyone.

Full Text Available In the next generation of heterogeneous wireless networks (HWNs, a large number of different radio access technologies (RATs will be integrated into a common network. In this type of networks, selecting the most optimal and promising access network (AN is an important consideration for overall networks stability, resource utilization, user satisfaction, and quality of service (QoS provisioning. This paper proposes a general scheme to solve the access network selection (ANS problem in the HWN. The proposed scheme has been used to present and design a general multicriteria software assistant (SA that can consider the user, operator, and/or the QoS view points. Combined fuzzy logic (FL and genetic algorithms (GAs have been used to give the proposed scheme the required scalability, flexibility, and simplicity. The simulation results show that the proposed scheme and SA have better and more robust performance over the random-based selection.

Full Text Available New methodologies, engineering processes, and support environments are beginning to emerge for embedded signal processing systems. The main objectives are to enable defence industry to field state-of-the-art products in less time and with lower costs, including retrofits and upgrades, based predominately on commercial off the shelf (COTS components and the model-year concept. One of the cornerstones of the new methodologies is the concept of rapid prototyping. This is the ability to rapidly and seamlessly move from functional design to the architectural design to the implementation, through automatic code generation tools, onto real-time COTS test beds. In this paper, we try to quantify the term Ã¢Â€ÂœrapidÃ¢Â€Â and provide results, the metrics, from two independent benchmarks, a radar and sonar beamforming application subset. The metrics show that the rapid prototyping process may be sixteen times faster than a conventional process.

Full Text Available Background Infection caused by rapidly growing mycobacteria (RGM is not uncommon, andthe prevalence of RGM infection has been increasing. Clinical diagnosis is difficult becausethere are no characteristic clinical features. There is also no standard antibiotic regimenfor treating RGM infection. A small series of patients with RGM infections was studied toexamine their treatments and outcomes.Methods A total of 5 patients who had developed postoperative infections from January2009 to December 2010 were retrospectively reviewed. Patients were initially screened using amycobacteria rapid screening test (polymerase chain reaction [PCR]-reverse blot hybridizationassay. To confirm mycobacterial infection, specimens were cultured for nontuberculousmycobacteria and analyzed by 16 S ribosomal RNA and rpoB gene PCR.Results The patients were treated with intravenous antibiotics during hospitalization,and oral antibiotics were administered after discharge. The mean duration of follow-upwas 9 months, and all patients were completely cured of infection with a regimen of acombination of antibiotics plus surgical treatment. Although none of the patients developedrecurrence, there were complications at the site of infection, including hypertrophic scarring,pigmentation, and disfigurement.Conclusions Combination antibiotic therapy plus drainage of surgical abscesses appeared tobe effective for the RGM infections seen in our patients. Although neither the exact dosagenor a standardized regimen has been firmly established, we propose that our treatment canprovide an option for the management of rapidly growing mycobacterial infection.

Full Text Available Introduction: Architectural barriers generate difficulties, significantly impair people’s access to different environments, and limit accessibility. In the Brazilian public school system, these questions become more relevant when the process of school inclusion of students with special needs for mobility is analyzed. The process of school inclusion is intrinsically associated with the accessibility condition of schools. Through the ‘Accessible School Program‘, schools have received financial incentive to adapt their physical spaces according to accessibility. Objective: To describe the accessibility of the schools that have taken part in the ‘Accessible School Program’ in the municipality of Uberaba, Minas Gerais state. The study also aimed to identify the materials purchased and the adjustments and repairs implemented, evaluating whether the changes attend the technical standard of accessibility and agree with the recommended proposals. Methodology: This is an exploratory-descriptive study of quantitative nature; it was conducted in two phases through documental research and field study. Eleven municipal schools that participated in the ‘Accessible School Program’ were identified. Results: Most of the schools presented problems in almost all the items evaluated: sidewalks, common inside area, door squares, restrooms, locker rooms, swimming pools, parking, cinemas or theatres, auditoriums, stadiums, gymnasiums, concert halls, conference rooms and school furniture. Conclusion: The public schools evaluated present limitations regarding accessibility; the physical barriers erected in the past have not been eliminated and they still represent obstacles to be overcome by students with special needs.
Full Text Available Localization of access points has become an important research problem due to the wide range of applications it addresses such as dismantling critical security threats caused by rogue access points or optimizing wireless coverage of access points within a service area. Existing proposed solutions have mostly relied on theoretical hypotheses or computer simulation to demonstrate the efficiency of their methods. The techniques that rely on estimating the distance using samples of the received signal strength usually assume prior knowledge of the signal propagation characteristics of the indoor environment in hand and tend to take a relatively large number of uniformly distributed random samples. This paper presents an efficient and practical collaborative approach to detect the location of an access point in an indoor environment without any prior knowledge of the environment. The proposed approach comprises a swarm of wirelessly connected mobile robots that collaboratively and autonomously collect a relatively small number of non-uniformly distributed random samples of the access point’s received signal strength. These samples are used to efficiently and accurately estimate the location of the access point. The experimental testing verified that the proposed approach can identify the location of the access point in an accurate and efficient manner.

Internet-based health-record management requires not only the provision of strong data protection to prevent privacy intrusion and unauthorized access, but also the introduction of a common healthcare-record format to allow cooperation using heterogeneous repositories held at various hospitals. A secure multi-agent architecture is proposed for accessing healthcare information through the Internet from multiple heterogeneous repositories. The proposed system is organized into a four-tier architecture that consists of client applications, a central access-control system, local access-control systems, and hospital information systems. The eXtensible Markup Language (XML) and the role-based access-control (RBAC) system are combined for efficient repository management by providing methods for access-control, information exchange, user authentication, data integrity, and selective encryption. A multi-agent architecture using XML and RBAC can interconnect heterogeneous repositories with different formats and different hospital policies, and allow them to communicate securely. The authorized client, having confirmed access privileges, can retrieve the requested healthcare data in an XML-based common data format with embedded confidentiality. The proposed method for Internet-based exchange of patient data is particularly useful for cooperative healthcare and the creation of lifetime healthcare records.

Full Text Available Some of the stress related topics, especially from the conceptual framework of Lazarus and Folkman are reviewed on this work. It is sustained that this approach is dualistic and that the research made from this view is made on the basis of morphological criteria that don’t allow studying important elements of this kind of behavior. From an interbehavioral approach three functional criteria are proposed to study this phenomenon: the functional nature of situations, aptitude levels of behavior, and its three dimensions. Emphasis is made on the singular and individual nature of stress reactions. Finally it is suggested to take into account these functional criteria to develop a generic situational taxonomy to study these reactions as parts of complex behavioral patterns.

Full Text Available Cellular network is provisioned to serve traffic demands generated by human being. The random access channel used for nodes to compete for a connection with an eNB is limited. Even though machines generate very small amount of data traffic, the signaling channel of a network becomes overloaded and collisions occur to fail the access if too many MTC (Machine Type Communication devices attempt to access network. To tackle the issue, 3GPP specifies an access class barring but leaves a specific algorithm as an implementation issue. In this paper, we propose an adaptive access barring method. Generally, an eNB does not know the number of MTC devices in its coverage area. Thus, it is difficult to control the barring factor by predicting the number of MTC devices in a service area of a cell. On the contrary, we control the barring factor based on the prediction of access intensity which can be measured at an eNB. Simulation results show that since the proposed method can manipulate the barring factor autonomously according to the access intensity, it is superior to the original method in terms of the access success probability and the collision probability.

We combined the advantage of an ultrafast random access microscope with novel labelling technologies to study the intra- and inter-cellular action potential propagation in neurons and cardiac myocytes with sub-millisecond time resolution. The random accesses microscopy was used in combination with a new fluorinated voltage sensitive dye with improved photostability to record membrane potential from multiple Purkinje cells with near simultaneous sampling. The RAMP system rapidly scanned between lines drawn in the membranes of neurons to perform multiplex measurements of the TPF signal. This recording was achieved by rapidly positioning the laser excitation with the AOD to sample a patch of membrane from each cell in <100 μs for recording from five cells, multiplexing permits a temporal resolution of 400 μs sufficient to capture every spike. The system is capable to record spontaneous activity over 800 ms from five neighbouring cells simultaneously, showing that spiking is not temporally correlated. The system was also used to investigate the electrical properties of tubular system (TATS) in isolated rat ventricular myocytes.

Full Text Available This paper proposes a virtualized network function orchestration system based on Network Function Virtualization (NFV, one of the main technologies in 5G mobile networks. This system should provide connectivity between network devices and be able to create flexible network function and distribution. This system focuses more on access networks. By experimenting with various scenarios of user service established and activated in a network, we examine whether rapid adoption of new service is possible and whether network resources can be managed efficiently. The proposed method is based on Bluetooth transfer technology and mesh networking to provide automatic connections between network machines and on a Docker flat form, which is a container virtualization technology for setting and managing key functions. Additionally, the system includes a clustering and recovery measure regarding network function based on the Docker platform. We will briefly introduce the QR code perceived service as a user service to examine the proposal and based on this given service, we evaluate the function of the proposal and present analysis. Through the proposed approach, container relocation has been implemented according to a network device’s CPU usage and we confirm successful service through function evaluation on a real test bed. We estimate QR code recognition speed as the amount of network equipment is gradually increased, improving user service and confirm that the speed of recognition is increased as the assigned number of network devices is increased by the user service.

Full Text Available The optical fibre is the highest quality transmission mediumfor broadband services, and therefore the new access cablenetwork has to be realized to the greatest extent and as closeas possible to the subscriber by means of the optical fibre cables,in accordance with the possibilities of the telecommunicationoperator. The development of digital technology in commutations,supported by the increasingly powerful systems of processorcontrol, development of optical communications andtransport technologies in the framework of SDH concepts, arereflected on the access telecommunication networks of the urbanareas. Urban areas are the most profitable regions in telecommunications.In planning of urban optical networks the fact should betaken as a guideline that only a well-organised urban networkwill allow high quality of service provision of the leased cablesto the end points of business customers.Business customers have greater requirements for the networkreliability, flexibility and maintainability, for the sake ofundisturbed telecommunication traffic.The optical medium based technology- FITL (fiber in theloop, provides almost limitless upgrading of the system regardingthe transmission bandwidths, as well as adaptation to allthe future customers' requirements.Considering the increase in the price of installing the coppercables, the prices of electronics and optical components arecontinuously falling. The application of the optical medium isincreasing and becoming more cost-effective, and due to higherreliability of the optical transmission systems the maintenancecosts are reduced.

Full Text Available Digital pathology is rapidly developing, but early systems have been slow to gain traction outside of niche applications such as: Second-opinion telepathology, immunostain interpretation, and intraoperative telepathology. Pathologists have not yet developed a well-articulated plan for effectively utilizing digital imaging technology in their work. This paper outlines a proposal that is intended to begin meaningful progress toward achieving helpful computer-assisted pathology sign-out systems, such as pathologists′ computer-assisted diagnosis (pCAD. pCAD is presented as a hypothetical intelligent computer system that would integrate advanced image analysis and better utilization of existing digital pathology data from lab information systems. A detailed example of automated digital pathology is presented, as an automated breast cancer lymph node sign-out. This proposal provides stakeholders with a conceptual framework that can be used to facilitate development work, communication, and identification of new automation strategies.

Access to previous results and their reuse in new research are at the very basis of scientific progress. In the era of e-Science and when the Open Access paradigm is changing scholarly communication, there is an unprecedented need for rapid and effective online access to scientific information. High-Energy Physics (HEP) pioneered innovation in scholarly communication with the invention of the Web, originally a vehicle of scientific information, and with the inception of online preprint repositories, introducing Open Access to preliminary scientific results. With the imminent start-up of the CERN LHC accelerator, one of the flagships of European science, the HEP community urgently needs a new platform for scientific information. A multi-disciplinary collaboration of academies, research laboratories and industrial partners has developed a vision to build such an innovative e-infrastructure: HEPIS (High Energy Physics Information System). HEPIS will integrate present European and American databases and repositor...
Full Text Available The move from IP-based authentication to that of federated access has seen the sector support single sign-on to web-based resources, but the simplified user experience is at risk due to the rapid growth of mobile platforms and increasing variety of accompanying access methods for such devices. The user authentication experience on mobile devices is often further complicated by the poor discovery and delivery design of websites. While the introduction of tools such as Raptor permit accurate tracking of usage statistics via the UK Access Management Federation, the variety of mobile authentication methods such as native apps on devices and device paring pose additional challenges to librarians trying to gather a complete picture of resource use within their institution. In this article we examine the access challenges posed by the explosion of mobile device use.

Full Text Available The security challenges being encountered in many places require electronic means of controlling access to communities, recreational centres, offices, and homes. The electronically controlled automated security access gate being proposed in this work helps to prevent an unwanted access to controlled environments. This is achieved mainly through the use of a Radio Frequency (RF transmitter-receiver pair. In the design a microcontroller is programmed to decode a given sequence of keys that is entered on a keypad and commands a transmitter module to send out this code as signal at a given radio frequency. Upon reception of this RF signal by the receiver module, another microcontroller activates a driver circuitry to operate the gate automatically. The codes for the microcontrollers were written in C language and were debugged and compiled using the KEIL Micro vision 4 integrated development environment. The resultant Hex files were programmed into the memories of the microcontrollers with the aid of a universal programmer. Software simulation was carried out using the Proteus Virtual System Modeling (VSM version 7.7. A scaled-down prototype of the system was built and tested. The electronically controlled automated security access gate can be useful in providing security for homes, organizations, and automobile terminals. The four-character password required to operate the gate gives the system an increased level of security. Due to its standalone nature of operation the system is cheaper to maintain in comparison with a manually operated type.

Timely testing of women in labor with undocumented human immunodeficiency virus (HIV) status could enable immediate provision of antiretroviral prophylaxis. To determine the feasibility and acceptance of rapid HIV testing among women in labor and to assess rapid HIV assay performance. The Mother-Infant Rapid Intervention At Delivery (MIRIAD) study implemented 24-hour counseling and voluntary rapid HIV testing for women in labor at 16 US hospitals from November 16, 2001, through November 15, 2003. A rapid HIV-1 antibody test for whole blood was used. Acceptance of HIV testing; sensitivity, specificity, and predictive value of the rapid test; time from blood collection to patient notification of results. There were 91,707 visits to the labor and delivery units in the study, 7381 of which were by eligible women without documentation of HIV testing. Of these, 5744 (78%) women were approached for rapid HIV testing and 4849 (84%) consented. HIV-1 test results were positive for 34 women (prevalence = 7/1000). Sensitivity and specificity of the rapid test were 100% and 99.9%, respectively; positive predictive value was 90% compared with 76% for enzyme immunoassay (EIA). Factors independently associated with higher test acceptance included younger age, being black or Hispanic, gestational age less than 32 weeks, and having had no prenatal care. Lower acceptance was associated with being admitted between 4 pm and midnight, particularly on Friday nights, but this may be explained in part by fewer available personnel. Median time from blood collection to patient notification of result was 66 minutes (interquartile range, 45-120 minutes), compared with 28 hours for EIA (PHIV testing is feasible and delivers accurate and timely test results for women in labor. It provides HIV-positive women prompt access to intrapartum and neonatal antiretroviral prophylaxis, proven to reduce perinatal HIV transmission, and may be particularly applicable to higher-risk populations.

The Web Science framework poses fundamental questions on the analysis of the Web, by focusing on how microscopic properties (e.g. at the level of a Web page or Web site) emerge into macroscopic properties and phenomena. One research topic on the analysis of the Web is Web accessibility evaluation, which centres on understanding how accessible a Web page is for people with disabilities. However, when framing Web accessibility evaluation on Web Science, we have found that existing research stays at the microscopic level. This article presents an experimental study on framing Web accessibility evaluation into Web Science's goals. This study resulted in novel accessibility properties of the Web not found at microscopic levels, as well as of Web accessibility evaluation processes themselves. We observed at large scale some of the empirical knowledge on how accessibility is perceived by designers and developers, such as the disparity of interpretations of accessibility evaluation tools warnings. We also found a direct relation between accessibility quality and Web page complexity. We provide a set of guidelines for designing Web pages, education on Web accessibility, as well as on the computational limits of large-scale Web accessibility evaluations.

e-Government organisations are facilitated and conducted using workflow management systems. Role-based access control (RBAC) is recognised as an efficient access control model for large organisations. The application of RBAC in workflow systems cannot, however, grant permissions to users dynamically while business processes are being executed. We currently observe a move away from predefined strict workflow modelling towards approaches supporting flexibility on the organisational level. One specific approach is that of task delegation. Task delegation is a mechanism that supports organisational flexibility, and ensures delegation of authority in access control systems. In this paper, we propose a Task-oriented Access Control (TAC) model based on RBAC to address these requirements. We aim to reason about task from organisational perspectives and resources perspectives to analyse and specify authorisation constraints. Moreover, we present a fine grained access control protocol to support delegation based on the TAC model.

The ASGE Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, performing a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported complications of a given technology. Both are supplemented by accessing the "related articles" feature of PubMed and by scrutinizing pertinent references cited by the identified studies. Controlled clinical trials are emphasized, but, in many cases, data from randomized, controlled trials are lacking. In such situations, large case series, preliminary clinical studies, and expert opinions are used. Technical data are gathered from traditional and Web-based publications, proprietary publications, and informal communications with pertinent vendors. Technology Status Evaluation Reports are drafted by 1 or 2 members of the ASGE Technology Committee, reviewed and edited by the committee as a whole, and approved by the ASGE Governing Board. When financial guidance is indicated, the most recent coding data and list prices at the time of publication are provided. For this review, the MEDLINE database was searched through August 2009 for articles related to endoscopy in patients requiring enteral feeding access by using the keywords "endoscopy," "percutaneous," "gastrostomy," "jejunostomy," "nasogastric," "nasoenteric," "nasojejunal," "transnasal," "feeding tube," "enteric," and "button." Technology Status Evaluation Reports are scientific reviews provided solely for educational and informational purposes.

There is a widespread and growing concern that patents hinder access to life-saving drugs in developing countries. Recent student movements and legislative initiatives emphasize the potential role that research universities in developed countries could have in ameliorating this “access gap.” These efforts are based on the assumption that universities own patents on a substantial number of drugs and that patents on these drugs are currently filed in developing countries. I provide empirical evidence regarding these issues and explore the feasibility and desirability of proposals to change university patenting and licensing practices to promote access to medicines in the developing world.

Full Text Available In Socratic philosophy, human beings had access to an inner voice that could be counted on to provide guidance and assistance when needed. This inner voice or daemon was always available and had access to realms of knowledge that mortal consciousness did not have. We propose that the field of Machine Learning has reached the level of maturity where the construction of a personal daemon is now feasible. The ubiquity of broadband access to the internet can guarantee that this personal daemon is always available. Such a construct can greatly increase the efficacy and availability of education for all citizens.

The rapid growth of the Internet is increasingly international with young people being the early adopters in most countries. However, the quality of Internet access looms as a major barrier hidden behind Internet use statistics. The goal of this study was to provide an in-depth evaluation of young people's perspectives on using the Internet to obtain health information and resources (e-health). Using an inductive qualitative research design, 27 focus groups were conducted in Ontario, Canada. The 210 young participants were selected to reflect diversity in age, sex, geographic location, cultural identity and risk. A major finding was how the quality of Internet access influenced young people's ability to obtain health information and resources. Quality of Internet access was affected by four key factors: 1. Privacy, 2. Gate-keeping, 3. Timeliness and 4. Functionality. Privacy was particularly relevant to these young people in getting access to sensitive health information (e.g. sexual activities). Variations in access quality also impacted participation in mutual support, fostering social networks and getting specific health questions answered. These results serve as a warning about using Internet penetration statistics alone as a measure of access. Concerted attention is needed on improving the quality of Internet access for achieving the potential of e-health. This is imperative for addressing the digital divide affecting populations both within countries and globally between countries.
Full Text Available Abstract Background As the population is ageing rapidly in Beijing, the residential care sector is in a fast expansion process with the support of the municipal government. Understanding spatial accessibility to residential care resources by older people supports the need for rational allocation of care resources in future planning. Methods Based on population data and data on residential care resources, this study uses two Geographic Information System (GIS based methods – shortest path analysis and a two-step floating catchment area (2SFCA method to analyse spatial accessibility to residential care resources. Results Spatial accessibility varies as the methods and considered factors change. When only time distance is considered, residential care resources are more accessible in the central city than in suburban and exurban areas. If care resources are considered in addition to time distance, spatial accessibility is relatively poor in the central city compared to the northeast to southeast side of the suburban and exurban areas. The resources in the northwest to southwest side of the city are the least accessible, even though several hotspots of residential care resources are located in these areas. Conclusions For policy making, it may require combining various methods for a comprehensive analysis. The methods used in this study provide tools for identifying underserved areas in order to improve equity in access to and efficiency in allocation of residential care resources in future planning.

Recognition of pictures is typically extremely accurate, and it is thus unclear whether the reconstructive nature of memory can yield substantial false recognition of highly individuated stimuli. A procedure for the rapid induction of false memories for distinctive colour photographs is proposed. Participants studied a set of object pictures followed by a list of words naming those objects, but embedded in the list were names of unseen objects. When subsequently shown full colour pictures of these unseen objects, participants consistently claimed that they had seen them, while discriminating with high accuracy between studied pictures and new pictures whose names did not appear in the misleading word list. These false memories can be reported with high confidence as well as the feeling of recollection. This new procedure allows the investigation of factors that influence false memory reports with ecologically valid stimuli and of the similarities and differences between true and false memories.

The emergence of Web 2.0 technologies such as Ajax and Mashup has revealed the weakness of the same-origin policy, the current de facto standard for the Web browser security model. We propose a new browser security model to allow fine-grained access control in the client-side Web applications for secure mashup and user-generated contents. We propose a browser security model that is based on information-flow-based access control (IBAC) to overcome the dynamic nature of the client-side Web applications and to accurately determine the privilege of scripts in the event-driven programming model.

Full Text Available Abstract In 2012, the Open Access Movement to scientific information celebrated ten years of existence. The period, which represents the first stage of consolidation of the movement, has been analyzed to allow the planning of new phases. With the purpose of providing tools and contributing to these discussions, the article addresses the historical aspects of the international and regional constitution of Open Access Movement. The approach was developed from a descriptive temporal narrative of the main events and initiatives identified in the scientific literature on the subject. The elements discussed in the present study work were organized under two parameters. The first refers to a temporal perspective, defined from the publication of Budapest Open Access Initiative. The second is related to brief discussion of the participation of Latin America. As result, we present a timeline of open access in the world and in Latin America, showing the main aspects covered in the study. The goal of the study is achieved by the proposed systematization as we analyze the open access initiatives in Latin America and establish how they influenced and were influenced by other regions of the world.
Full Text Available Although repeated contact with nature helps foster mental and physical health among young people, their contact with nature has been diminishing over the last few decades. Also, low-income and ethnic minority children have even less contact with nature than white middle-income children. In this study, we compared accessibility to play in parks for young people from different income and racial backgrounds in Denver, Colorado. Park access for children and youth was measured using a geographic information system (GIS. Each neighborhood was classified according to income level, residential density, and distance from downtown; and then each park was classified based on formal and informal play, and level of intimacy. Comparisons between neighborhoods show that that low-income neighborhoods have the lowest access and high-income neighborhoods have the highest access to parks, and that differences are even higher for parks with play amenities and high levels of intimacy. To overcome this issue, the paper proposes a framework for action to improve access to parks for low-income children and youth and to help planners, decision makers and advocacy groups prioritize park investments.

The Regulatory and Permitting Information Desktop (RAPID) Toolkit combines the former Geothermal Regulatory Roadmap, National Environmental Policy Act (NEPA) Database, and other resources into a Web-based tool that gives the regulatory and utility-scale geothermal developer communities rapid and easy access to permitting information. RAPID currently comprises five tools - Permitting Atlas, Regulatory Roadmap, Resource Library, NEPA Database, and Best Practices. A beta release of an additional tool, the Permitting Wizard, is scheduled for late 2014. Because of the huge amount of information involved, RAPID was developed in a wiki platform to allow industry and regulatory agencies to maintain the content in the future so that it continues to provide relevant and accurate information to users. In 2014, the content was expanded to include regulatory requirements for utility-scale solar and bulk transmission development projects. Going forward, development of the RAPID Toolkit will focus on expanding the capabilities of current tools, developing additional tools, including additional technologies, and continuing to increase stakeholder involvement.

Developmental evolution has frequently been identified as a mode for rapid adaptation, but direct observations of the selective benefits and associated mechanisms of developmental evolution are necessarily challenging to obtain. Here we show rapid evolution of greatly increased rates of dispersal by developmental changes when populations experience stringent selection. Replicate populations of the filamentous fungus Trichoderma citrinoviride underwent 85 serial transfers, under conditions initially favoring growth but not dispersal. T. citrinoviride populations shifted away from multicellular growth toward increased dispersal by producing one thousand times more single-celled asexual conidial spores, three times sooner than the ancestral genotype. Conidia of selected lines also germinated fifty percent faster. Gene expression changed substantially between the ancestral and selected fungi, especially for spore production and growth, demonstrating rapid evolution of tight regulatory control for down-regulation of growth and up-regulation of conidia production between 18 and 24 hours of growth. These changes involved both developmentally fixed and plastic changes in gene expression, showing that complex developmental changes can serve as a mechanism for rapid adaptation.

In the Bioenergy and Defense Department of Sandia National Laboratories, characterization of the BaDx (Bacillus anthracis diagnostic cartridge) was performed and rapid germination chemistry was investigated. BaDx was tested with complex sample matrixes inoculated with Bacillus anthracis, and the trials proved that BaDx will detect Bacillus anthracis in a variety of the medium, such as dirt, serum, blood, milk, and horse fluids. The dimensions of the device were altered to accommodate an E. coli or Listeria lateral flow immunoassay, and using a laser printer, BaDx devices were manufactured to identify E. coli and Listeria. Initial testing with E. coli versions of BaDx indicate that the device will be viable as a portable diagnostic cartridge. The device would be more effective with faster bacteria germination; hence studies were performed the use of rapid germination chemistry. Trials with calcium dipicolinic acid displayed increased cell germination, as shown by control studies using a microplate reader. Upon lyophilization the rapid germination chemistry failed to change growth patterns, indicating that the calcium dipicolinic acid was not solubilized under the conditions tested. Although incompatible with the portable diagnostic device, the experiments proved that the rapid germination chemistry was effective in increasing cell germination.

Recent studies have shown significant warming of inland water bodies around the world. Many lakes are warming more rapidly than the ambient surface air temperature, and this is counter to what is often expected based on the lake surface energy balance. A host of reasons have been proposed to explain these discrepancies, including changes in the onset of summer stratification, significant loss of ice cover, and concomitant changes in winter air temperature and/or summer cloud cover. A review of the literature suggests that no single physical mechanism is primarily responsible for the majority of these changes, but rather that the large heterogeneity in regional climate trends and lake geomorphometry results in a host of potential physical drivers. In this study, we discuss the variety of mechanisms that have been proposed to explain rapid lake warming and offer an assessment of the physical plausibility for each potential contributor. Lake Superior is presented as a case study to illustrate the "perfect storm" of factors that can cause a deep, dimictic lake to warm at rate that exceeds the rate of global air temperature warming by nearly an order of magnitude. In particular, we use a simple mixed-layer model to show that spatially variable trends in Lake Superior surface water temperature are determined, to first order, by variations in bathymetry and winter air temperature. Summer atmospheric conditions are often of less significance, and winter ice cover may simply be a correlate. The results highlight the importance of considering the full range of factors that can lead to trends in lake surface temperature, and that conventional wisdom may often not be the best guide.

This brief investigates distributed medium access control (MAC) with QoS provisioning for both single- and multi-hop wireless networks including wireless local area networks (WLANs), wireless ad hoc networks, and wireless mesh networks. For WLANs, an efficient MAC scheme and a call admission control algorithm are presented to provide guaranteed QoS for voice traffic and, at the same time, increase the voice capacity significantly compared with the current WLAN standard. In addition, a novel token-based scheduling scheme is proposed to provide great flexibility and facility to the network servi

A tool based on IDL (Interactive Data Language) and DAP (Data Access Protocol) has been developed for user-friendly remote data access. A difficulty for many NASA researchers using IDL is that often the data to analyze are located remotely and are too large to transfer for local analysis. Researchers have developed a protocol for accessing remote data, DAP, which is used for both SOHO and STEREO data sets. Server-side side analysis via IDL routine is available through DAP.

Full Text Available This article presents the project that I led for HEFCE on the implications of OA (open access for monographs and other long-form research publications. The likely requirement that books should be OA if submitted to the REF (Research Excellence Framework after next means that OA development must be based on an understanding of the importance of the monograph in the AHSS (arts, humanities and social sciences as well as the challenges involved in making the transition to online OA. The project focused on three issues and each is summarized in turn in the article: What is the place of the monograph and other long-form publications in AHSS disciplines that makes it so important? What is happening to the monograph and is there a crisis as some suggest? What are the issues involved in moving monographs into a digital and OA environment – not just the challenge of effective business models but also many other aspects of sustaining and enhancing the qualities of the monograph? These include third-party rights, technical challenges, licences and the need for international collaboration.

To report the first single port access (SPA) adrenalectomy to minimize patient discomfort through a less invasive procedure. We performed the first SPA in a 63-year-old, otherwise healthy Caucasian female who had a 4.5-cm left adrenal mass that was incidentally discovered on computed tomography scan of the abdomen and pelvis. Through a 2-cm single longitudinal supraumbilical incision extended down to the abdominal fascia, three 5-mm ports were placed through separate facial entry points, to make a triangular port arrangement. The adrenal vein was identified and ligated using hemoclips. The remainder of the dissection was done using hemocoagulation. The adrenal gland was extracted via an EndoCatch bag device by removing one 5-mm port and upsizing to a 12-mm port. We report on the first SPA adrenalectomy. Although this technology is still in its infancy, the use of a single port for surgery provides a means to provide a potentially better patient outcome with a less invasive procedure.

A new semester begins, and your students enter the classroom for the first time. You notice a student sitting in a wheelchair or walking with assistance from a cane. Maybe you see a student with a guide dog or carrying a Braille computer. Another student gestures "hello” but then continues hand motions, and you realize the person is actually signing. You wonder why another student is using an electronic device to speak. Think this can't happen in your class? According to the U.S. Census, one out of every five Americans has a disability. And some disabilities, such as autism, dyslexia and arthritis, are considered "invisible” disabilities. This means you have a high probability that one of your students will have a disability. As an astronomy instructor, you have the opportunity to reach a wide variety of learners by using creative teaching strategies. I will share some suggestions on how to make astronomy and your part of the universe more accessible for everyone.

The paper considers the role a Public Access Space Suit (PASS) could have in the certification of Reusable Launch Vehicles (RLVs) for use in space tourism and other non-government activities. Two distinct classes of hazards are highlighted. The first class involve hazards which are common with civil aircraft but where the RLV exacerbates the safety issue. The second class of hazard are those unique to RLVs. From consideration of these hazards a specification for the PASS is derived. Also the additional roles the PASS could have on a space station are considered both as a continuation of the safety role and a means by which tourists could experience recreational “spacewalks”. It is shown no significant additional requirements are generated to perform these extra roles. A feasibility design for a PASS is presented showing how these requirements could be met. The PASS concept derived in this paper is intended to be an input into the overall evaluation of costs and approaches to space tourism with the objective of exploring whether it is the best route, not only to meet safety requirements, but also to enhance the marketability of any space tourism venture.

The theoretically proven security of quantum key distribution (QKD) could revolutionize the way in which information exchange is protected in the future. Several field tests of QKD have proven it to be a reliable technology for cryptographic key exchange and have demonstrated nodal networks of point-to-point links. However, until now no convincing answer has been given to the question of how to extend the scope of QKD beyond niche applications in dedicated high security networks. Here we introduce and experimentally demonstrate the concept of a 'quantum access network': based on simple and cost-effective telecommunication technologies, the scheme can greatly expand the number of users in quantum networks and therefore vastly broaden their appeal. We show that a high-speed single-photon detector positioned at a network node can be shared between up to 64 users for exchanging secret keys with the node, thereby significantly reducing the hardware requirements for each user added to the network. This point-to-multipoint architecture removes one of the main obstacles restricting the widespread application of QKD. It presents a viable method for realizing multi-user QKD networks with efficient use of resources, and brings QKD closer to becoming a widespread technology.

Atomic memory access requests are handled using a variety of systems and methods. According to one example method, a data-processing circuit having an address-request generator that issues requests to a common memory implements a method of processing the requests using a memory-access intervention circuit coupled between the generator and the common memory. The method identifies a current atomic-memory access request from a plurality of memory access requests. A data set is stored that corresponds to the current atomic-memory access request in a data storage circuit within the intervention circuit. It is determined whether the current atomic-memory access request corresponds to at least one previously-stored atomic-memory access request. In response to determining correspondence, the current request is implemented by retrieving data from the common memory. The data is modified in response to the current request and at least one other access request in the memory-access intervention circuit.
Full Text Available The sudden growth of additive manufacturing is generating a renovated interest towards the field of rapid tooling. We propose a geometrical compensation method for rapid tools made by thermoset polyurethane. The method is based on the explicit FEM simulation coupled to a geometrical optimization algorithm for designing the stamping tools. The compensation algorithm is enhanced by considering the deviations between the stamped and designed components. The FEM model validation has been performed by comparing the results of a DOE done at different values of press force.

Full Text Available Thermal behavior of electronic equipment is the determining factor for performing rapid assessment of the effectiveness of design and operation of the equipment. The assessment method proposed in this article consists in fixation of an infrared video stream from the surface of the device and converting it into a visible flow by means of a thermal imager, splitting it into component colors and their further processing using parabolic transformation. The result of the transformation is the number used as a rapid criterion for estimation of distribution stability of heat in the equipment.

Drug-induced liver injury is a major cause of safety-related drug-marketing withdrawals. Several drugs have been reported to disrupt mitochondrial function, resulting in hepatotoxicity. The development of a simple and effective in vitro assay to identify the potential for mitochondrial toxicity is thus desired to minimize the risk of causing hepatotoxicity and subsequent drug withdrawal. An in vitro test method called the "glucose-galactose" assay is often used in drug development but requires prior-culture of cells over several passages for mitochondrial adaptation, thereby restricting use of the assay. Here, we report a rapid version of this method with the same predictability as the original method. We found that replacing the glucose in the medium with galactose resulted in HepG2 cells immediately shifting their energy metabolism from glycolysis to oxidative phosphorylation due to drastic energy starvation; in addition, the intracellular concentration of ATP was reduced by mitotoxicants when glucose in the medium was replaced with galactose. Using our proposed rapid method, mitochondrial dysfunction in HepG2 cells can be evaluated by drug exposure for one hour without a pre-culture step. This rapid assay for mitochondrial toxicity may be more suitable for high-throughput screening than the original method at an early stage of drug development.
Some time ago it was the lack of public access to medical research data that really stirred the issue and gave inertia for legislation and a new publishing model that puts tax payer-funded medical research in the hands of those who fund it. In today's age global climate change has become the biggest socio-economic challenge, and the same argument resonates: climate affects us all and the publicly-funded science quantifying it should be freely accessible to all stakeholders beyond academic research. Over the last few years the ‘Open Access' movement to remove as much as possible subscription, and other on-campus barriers to academic research has rapidly gathered pace, but despite significant progress, the climate system sciences are not among the leaders in providing full access to their publications and data. Beyond the ethical argument, there are proven and tangible benefits for the next generation of climate researchers to adapt the way their output is published. Through the means provided by ‘open access', both data and ideas can gain more visibility, use and citations for the authors, but also result in a more rapid exchange of knowledge and ideas, and ultimately progress towards a sought solution. The presentation will aim to stimulate discussion and seek progress on the following questions: Should free access to climate research (& data) be mandatory? What are the career benefits of using ‘open access' for young scientists? What means and methods should, or could, be incorporated into current European graduate training programmes in climate research, and possible ways forward?

Computer aided diagnosis systems (CAD) have been developed to assist radiologists in the detection and diagnosis of abnormalities and a large number of pattern recognition techniques have been proposed to obtain a second opinion. Most of these strategies have been evaluated using different datasets making their performance incomparable. In this work, an open access database of thyroid ultrasound images is presented. The dataset consists of a set of B-mode Ultrasound images, including a complete annotation and diagnostic description of suspicious thyroid lesions by expert radiologists. Several types of lesions as thyroiditis, cystic nodules, adenomas and thyroid cancers were included while an accurate lesion delineation is provided in XML format. The diagnostic description of malignant lesions was confirmed by biopsy. The proposed new database is expected to be a resource for the community to assess different CAD systems.

Full Text Available According to policy commentators, decisions about how best to organise care involve trade-offs between factors relating to care quality, workforce, cost, and patient access. In England, proposed changes such as Emergency Department closures often face public opposition. This study examined the way communities respond to plans aimed at reorganising emergency services, including the trade-offs inherent in such decisions.Cross-sectional study involving in-depth interviews. Participants selected their priorities for emergency care, including aspects they might be prepared to have 'less' of (e.g. rapid access if it meant having 'more' of another (e.g. consultant-delivered care. A thematic analysis was carried out, combining inductive and deductive approaches, drawing on theories about risk perception.Two urban areas of England; one where changes to emergency services were under consideration ('Greenville', and one where they were not ('Hilltown'.28 participants in total. Greenville interviewees included more common emergency service users - parents of young children (n=5 and older people (n=6 - plus patient representatives and individuals campaigning against service closures (n=9. Hilltown interviewees (n=8 received outpatient care for Chronic Obstructive Pulmonary Disease, an important cause of emergency admission.Most participants, in both areas, were not willing to accommodate the trade-offs involved in consolidating emergency services, principally because of the belief that timely access is associated with better outcomes. Participants did not consider the proposed improvements as gains worth having; interviewees believed care quality would be adversely impact, partly because increased patient numbers would place staff under greater pressure and result in longer waiting times.Visible clinical leadership and detailed explanation of the case for change were insufficient to overcome opposition to the reconfiguration in Greenville, challenging the

The Operating Missions as Nodes on the Internet (OMNI) project at NASA's Goddard Space flight Center (GSFC), is demonstrating the use of standard Internet protocols for spacecraft communication systems. This year, demonstrations of Internet access to a flying spacecraft have been performed with the UoSAT-12 spacecraft owned and operated by Surrey Satellite Technology Ltd. (SSTL). Previously, demonstrations were performed using a ground satellite simulator and NASA's Tracking and Data Relay Satellite System (TDRSS). These activities are part of NASA's Space Operations Management Office (SOMO) Technology Program, The work is focused on defining the communication architecture for future NASA missions to support both NASA's "faster, better, cheaper" concept and to enable new types of collaborative science. The use of standard Internet communication technology for spacecraft simplifies design, supports initial integration and test across an IP based network, and enables direct communication between scientists and instruments as well as between different spacecraft, The most recent demonstrations consisted of uploading an Internet Protocol (IP) software stack to the UoSAT- 12 spacecraft, simple modifications to the SSTL ground station, and a series of tests to measure performance of various Internet applications. The spacecraft was reconfigured on orbit at very low cost. The total period between concept and the first tests was only 3 months. The tests included basic network connectivity (PING), automated clock synchronization (NTP), and reliable file transfers (FTP). Future tests are planned to include additional protocols such as Mobile IP, e-mail, and virtual private networks (VPN) to enable automated, operational spacecraft communication networks. The work performed and results of the initial phase of tests are summarized in this paper. This work is funded and directed by NASA/GSFC with technical leadership by CSC in arrangement with SSTL, and Vytek Wireless.
The US Department of Energy (DOE) has prepared an environmental assessment (EA) for the Rapid Reactivation Project at Sandia National Laboratories, New Mexico. The EA analyzes the potential effects of a proposal to increase production of neutron generators from the current capability of 600 units per year up to 2,000 units per year. The project would use existing buildings and infrastructure to the maximum extent possible to meet the additional production needs. The increased production levels would necessitate modifications and additions involving a total area of approximately 26,290 gross square feet at Sandia National Laboratories, New Mexico, Technical Area 1. Additional production equipment would be procured and installed. The no-action alternative would be to continue production activities at the current capability of 600 units per year. The EA analyzes effects on health, safety, and air quality, resulting from construction and operation and associated cumulative effects. A detailed description of the proposed action and its environmental consequences is presented in the EA.

Pharmacovigilance programmes can monitor and help ensure the safe use of medicines that are critical to the success of global public health programmes. The widespread deployment of artemisinin-based combination therapy (ACT) by national malaria control programmes as part of the overall Global Malaria Action Plan for malaria control to elimination and eradication makes ACT an excellent candidate for pharmacovigilance activities. In 2008, The Roll Back Malaria partnership issued guidelines for inclusion of pharmacovigilance in Global Fund and other related proposals. In light of this recommendation and the rapid scale-up of ACT worldwide, an analysis of Global Fund Round 8 proposals and the President's Malaria Initiative (PMI) 2009 Malaria Operational Plans was conducted to assess if and how pharmacovigilance has been incorporated into countries' national malaria plans and donor budget requests. The Global Fund-Malaria Round 8 proposals for the 26 countries and the PMI Malaria Operational Plans (MOPs) for fiscal year 2009 for the 15 countries that were approved and received funding from either the Global Fund-Malaria Round 8 or PMI were accessed through the programme websites. The analysis consisted of conducting word counts and key word in context analyses of each proposal and plan. Twelve out of 26 (46%) of the Global Fund proposals mentioned that established pharmacovigilance systems were present in their countries. Four of the fifteen PMI MOPs (27%) mentioned that established pharmacovigilance systems were present in their countries. Only seven of the 26 (27%) Global Fund proposals included a request for funding for new or current pharmacovigilance activities. Seven of 15 (47%) MOPs included a request for funding for pharmacovigilance activities. There were relatively few requests for funding for pharmacovigilance activities, demonstrating a lack of emphasis placed on pharmacovigilance systems in recipient countries. The findings stress the need for more active

Full Text Available While pulmonary tuberculosis (PTB remains an important public health issue worldwide, there is an emerging interest in non-tuberculous mycobacteria (NTM which is responsible for opportunistic infections of the respiratory tract as well as other anatomical sites in both developed and developing countries. In this context the one goal of the clinical mycobacteriology laboratories is to provide physicians with an accurate identification of the mycobacterium as rapidly as possible. During the last ten years, several lines of laboratory tools have been developed in order to speed the isolation and identification of mycobacteria from clinical specimens. Chiefly, the composition of culture medium was renewed along with the protocol of incubation in order to recover Mycobacterium tuberculosis (MTB micro-colonies as soon as 48 h after the inoculation of the specimen. MALDI-TOF rapid identification is clearly the tool to be implemented in the laboratory for the rapid identification of the micro-colonies. Also, molecular tools and genomics are necessary in order to depict new mycobacteria species, including those of the Mycobacterium abscessus complex and the Mycobacterium avium complex. All these tools and their connections will be presented during this conference.

The vision of the Global Earth Observation System of Systems (GEOSS) is the achievement of societal benefits through voluntary contribution and sharing of resources to better understand the relationships between the society and the environment where we live. To address complex issues in the field of geosciences a combined effort from many disciplines, ranging from physical to social sciences and including humanities, is required. The introduction of the Discovery and Access Broker (DAB) in the GEOSS Common Infrastructure (GCI) allowed to lower significantly the entry barriers for data users and producers, and thus to increase the order of magnitude of discoverable resources in the GCI, from hundreds of thousands to millions. This is a major step forward but from discovery to access, the road is still long! Either missing accessibility information in the metadata or broken links represent the major issue that prevents the real exploitation of the GCI resources. This is a remarkable problem for users attempting to exploit services and datasets obtained through a DAB query. This issue can be minimized providing the user with a ranked list of results that takes into account the real availability and accessibility of resources. We present in this work a methodology that overcomes the problem described above by improving the ranking algorithm, which is currently applied to the result set of a query to the DAB. The proposed methodology is based on the following steps: 1) Verify if information related to the accessibility of resources is described in the metadata provided by GEOSS contributors; 2) If accessibility information is provided, identify the type of resources (e.g. services, datasets) and produce modified and standardized accessibility information in a consistent manner; 3) Use standardized information to test accessibility and availability of resources using a probing approach; 4) Use the results returned in the ranking algorithm to assign the correct weight to

In the past decades, China has observed rapid urbanization, the nation's urban population reached 50% in 2000, and is still in steady increase. Rapid urbanization in China has an adverse impact on urban hydrological processes, particularly in increasing the urban flood risks and causing serious urban flooding losses. Urban flooding also increases health risks such as causing epidemic disease break out, polluting drinking water and damaging the living environment. In the highly urbanized area, non-engineering measurement is the main way for managing urban flood risk, such as flood risk warning. There is no mature method and pilot study for urban flood risk warning, the purpose of this study is to propose the urban flood risk warning method for the rapidly urbanized Chinese cities. This paper first presented an urban flood forecasting model, which produces urban flood inundation index for urban flood risk warning. The model has 5 modules. The drainage system and grid dividing module divides the whole city terrain into drainage systems according to its first-order river system, and delineates the drainage system into grids based on the spatial structure with irregular gridding technique; the precipitation assimilation module assimilates precipitation for every grids which is used as the model input, which could either be the radar based precipitation estimation or interpolated one from rain gauges; runoff production module classifies the surface into pervious and impervious surface, and employs different methods to calculate the runoff respectively; surface runoff routing module routes the surface runoff and determines the inundation index. The routing on surface grid is calculated according to the two dimensional shallow water unsteady flow algorithm, the routing on land channel and special channel is calculated according to the one dimensional unsteady flow algorithm. This paper then proposed the urban flood risk warning method that is called DPSIR model based
Full Text Available The present paper aims at unveiling the route of the proposed legal accessibility, seeking to develop a reflection inside the devices that support the process of social inclusion and education. Thus, studies in the area were used, also making reference to policies oriented for accessibility. So the research does not aspire to the exhaustion of the subject, but rather, it provides clues to a discussion of both to include accessibility in the scope of Special Education. There is a rescue on the law of accessibility including the Law No. 7405 of November 12, 1985, Law No. 10,048 of November 8, 2000, Law No. 10,098 of December 19, 2000 and Decree No. 5296 of 2 December 2004. Moreover, the ideas are on discussion according the current proposal of inclusive education, which refers to the access of everyone into the educational environment. Note that there are consistent policies regarding accessibility, however, in regard to the school environment, the barriers are not restricted only to the architectural features, or communications infrastructure. It has to agree, too, curricular and attitudinal adaptations as well as an assessment about the training.
On 11 May, a major change concerning the requirements to access the CERN beam facilities was put in place and implemented in ADaMS in order to reduce the number of courses that people who need access to multiple installations have to follow. This revision includes dedicated safety training courses that replace, in particular, the “Safety during LS1” e-learning course, which is now to be considered obsolete. CERN’s Access Distribution and Management System (ADaMS). As of 11 May, an important improvement was implemented in ADaMS (CERN’s Access Distribution and Management System) regarding the requisites to access safety zones. This change is closely related to the introduction of a generic e-learning course ("CERN Beam Facilities") covering the common risks and systems present in CERN's beam facilities. Two e-learning courses are no longer valid, nor available on the SIR (Safety Information Registration) catalogue: the &ld...

This one year LDRD addresses problems of threat assessment and restoration of facilities following a bioterror incident like the incident that closed down mail facilities in late 2001. Facilities that are contaminated with pathogenic spores such as B. anthracis spores must be shut down while they are treated with a sporicidal agent and the effectiveness of the treatment is ascertained. This process involves measuring the viability of spore test strips, laid out in a grid throughout the facility; the CDC accepted methodologies require transporting the samples to a laboratory and carrying out a 48 hr outgrowth experiment. We proposed developing a technique that will ultimately lead to a fieldable microfluidic device that can rapidly assess (ideally less than 30 min) spore viability and effectiveness of sporicidal treatment, returning facilities to use in hours not days. The proposed method will determine viability of spores by detecting early protein synthesis after chemical germination. During this year, we established the feasibility of this approach and gathered preliminary results that should fuel a future more comprehensive effort. Such a proposal is currently under review with the NIH. Proteomic signatures of Bacillus spores and vegetative cells were assessed by both slab gel electrophoresis as well as microchip based gel electrophoresis employing sensitive laser-induced fluorescence detection. The conditions for germination using a number of chemical germinants were evaluated and optimized and the time course of protein synthesis was ascertained. Microseparations were carried out using both viable spores and spores inactivated by two different methods. A select number of the early synthesis proteins were digested into peptides for analysis by mass spectrometry.
Full Text Available Despite the best efforts of networking researchers and practitioners, an ideal Internet experience is inaccessible to an overwhelming majority of people the world over, mainly due to the lack of cost-efficient ways of provisioning high-performance, global Internet. In this paper, we argue that instead of an exclusive focus on a utopian goal of universally accessible “ideal networking” (in which we have a high throughput and quality of service as well as low latency and congestion, we should consider providing “approximate networking” through the adoption of context-appropriate trade-offs. In this regard, we propose to leverage the advances in the emerging trend of “approximate computing” that rely on relaxing the bounds of precise/exact computing to provide new opportunities for improving the area, power, and performance efficiency of systems by orders of magnitude by embracing output errors in resilient applications. Furthermore, we propose to extend the dimensions of approximate computing towards various knobs available at network layers. Approximate networking can be used to provision “Global Access to the Internet for All” (GAIA in a pragmatically tiered fashion, in which different users around the world are provided a different context-appropriate (but still contextually functional Internet experience.
Increasing complexity of health care organization, rapid hyperspecialization of medical care, lack of ’patient literacy’ and pressure on patients to take over responsibility, challenges political dreams of equal access to patient centered high quality secure care....

In order to make use of the emerging grid and network services offered by various institutes and mandated by many current research projects, some kind of user accessible client is required. In contrast with attempts to build generic workbenches, Talisman is designed to allow a bioinformatics expert to rapidly build custom applications, immediately visible using standard web technology, for users who wish to concentrate on the biology of their problem rather than the informatics aspects. As a component of the MyGrid project, it is intended to allow access to arbitrary resources, including but not limited to relational, object and flat file data sources, analysis programs and grid based storage, tracking and distributed annotation systems.
