Lesion evidence for a critical role of left posterior but not frontal areas in alpha-beta power decreases during context-driven word production

Different frequency bands in the electroencephalogram are postulated to support distinct language functions. Studies have suggested that alpha-beta power decreases may index word-retrieval processes. In context-driven word retrieval, participants hear lead-in sentences that either constrain the final word (“He locked the door with the”) or not (“She walked in here with the”). The last word is shown as a picture to be named. Previous studies have consistently found alpha-beta power decreases prior to picture onset for constrained relative to unconstrained sentences, localised to the left lateral-temporal and lateral-frontal lobes. However, the relative contribution of temporal versus frontal areas to alpha-beta power decreases is unknown. We recorded the electroencephalogram from patients with stroke lesions encompassing the left-lateral temporal and inferior parietal regions or left-lateral frontal lobe and from matched controls. Individual-participant analyses revealed a behavioural sentence context facilitation effect in all participants, except for in the two patients with extensive lesions to temporal and inferior-parietal lobes. We replicated the alpha-beta power decreases prior to picture onset in all participants, except for in the two same patients with extensive posterior lesions. Thus, whereas posterior lesions eliminated the behavioural and oscillatory context effect, frontal lesions did not. Hierarchical clustering analyses of the patients’ lesion profiles, and behavioural and electrophysiological effects identified P7 and P9 as having a unique combination of lesion distribution and context effects. These results indicate a critical role for the left lateral-temporal and inferior parietal lobes, but not frontal cortex, in generating the alpha-beta power decreases underlying context-driven word production.
Towards high-quality 3D telepresence with commodity RGBD camera

3D telepresence aims at providing remote participants to have the perception of being present at the same physical space, which cannot be achieved by any 2D teleconference system. The success of 3D telepresence will greatly enhance communications, allowing much better user experience, which could stimulate many applications including teleconference, telesurgery, remote education, etc. Despite years of study, 3D telepresence research still faces many challenges such as high system cost, hard to achieve real-time performance with consumer-level hardware and high computation requirement, costly to obtain depth data, hard to extracting 3D people in real-time with high quality and difficult for 3D scene replacement and composition. The emerging of consumer-grade range cameras, such as Microsoft Kinect, which provides convenient and low-cost acquisition of 3D depth in real-time, accelerate many multimedia applications. In this thesis, we make a few attempts, aim at improving the quality of 3D telepresence with commodity RGBD camera. First, considering that the raw depth data of commodity depth camera is highly noisy and error-prone, we carefully study the error patterns of Kinect and propose a multi-scale direction-aware filtering method to combat Kinect noise. We have also implemented the proposed method in CUDA to achieve real-time performance. Experimental results show that our method outperforms the popular bilater filter. Second, we consider the problem of real-time extracting dynamic foreground person from RGB-D video, which is a common task in 3D telepresence. Existing methods are hard to ensure real time, high quality and temporal coherence at the same time. We propose a foreground extraction framework which nicely integrates many existing techniques including background subtraction, depth hole filing and 3D matting. We also take advantage of various CUDA strategies and spatial data structures to improve the speed. Experimental results show that, compared with state-of-the-art methods, our proposed method can extract stable foreground objects with
A REVIEW PAPER ON: THE EXPLOITING CONCEPT OF TWEETER NER OF SEGMENTATION

The information given on the social media is delivered to each and every person within some fraction of the second. The social networks such as Facebook or Twitter is the platform which is being widely used for posting what is happening? , what are the crimes happened? , what steps had been taken against that crime? , and it also give individual to express each and every emotion on such platform. The opinions changes to person to person and the posts may create a different impact on the individual. So the reaction may be positive or negative. The impact of the negative thought may be so strong that may result into social unrest. The social network some-times used for the planning the social unrest or gather people for such activity for example the candle march after some crimes, is the social unrest which has been mostly happened in India. There must be some tool or applications that can be used for detect such post and predict the Railway issues. Each and every post or action to be analyzed and then prediction is done whether the unrest will happen or not. Due to prediction of unrest before it happens will really help the investigator/police to prepare for that situation or to completely stop such activity. There is a need of such application which will predict the railway issues and this prediction will really help to get the details such as the location or the date.
A practical method for simulating AVHRR-consistent NDVI data series using narrow MODIS channels in the 0.5-1.0 μm spectral range

Over the past two decades, a key indicator of climate change has been the long time series of global maps of the normalized difference vegetation index (NDVI), derived from remotely sensed data acquired with a series of NOAA advanced very high resolution radiometer (AVHRR) instruments from space. These NDVI values are calculated from relatively broad AVHRR channels in the red and near-infrared regions. Continuation of this long term data set is extremely valuable for climate-related research, However, sometime in the coming decade, the AVHRR time series measurements will no longer be continued. Instead, the measurements will be made using newer generation satellite instruments having narrower channels and improved spatial resolution. For example, the moderate resolution imaging spectroradiometer (MODIS) onboard the Terra spacecraft has several narrow channels in the 0.4-1.0 spectral range. The NDVI values derived from the MODIS red channel and near-IR channel will be biased compared to those derived from the broader AVHRR channels because of differences in channel positions and widths for the two instruments. The narrow MODIS near-IR channel is only slightly affected by atmospheric water vapor absorption, while the broad AVHRR near-IR channel is strongly affected by water vapor absorption. As a result, the largest bias comes from the near-IR channels on the two instruments. To a lesser extent, the bias also comes from the differences between the red channel positions and the widths of MODIS and AVHRR instruments. In this paper, the authors describe a practical method for simulating AVHRR NDVI values using several narrower MODIS channels in the 0.4-1.0 /spl mu/m spectral range, including the MODIS green channel and the water vapor absorption channel.
Black adolescent mothers' perspectives on sex and parenting in nonmarital relationships with the biological fathers of their children.

OBJECTIVE To understand single Black adolescent mothers' perspectives on the sexual and parenting-related aspects of their relationships with the biological fathers of their children. METHODS The study was a qualitative description of perspectives from a convenience sample of Black single (nonmarried) adolescent mothers. Data were generated through focus groups and interviews. Participants were recruited using self-referral and health provider referrals. SETTING The study was conducted in a county public health department sexually transmitted diseases clinic in Rochester, New York. PARTICIPANTS Single mothers (N = 31) ages 15 to 19 participated in the study. The mean age of participants was 17.5 years (SD = 1.4). FINDINGS Four themes were identified that reflected the major characteristics of the relationships between the mothers and the biological fathers of their children: (a) You will always care about your "baby daddy" because of your child, (b) Negative behavior is tolerated to keep the family together, (c) The "baby daddy" can get sex as long as we are not on bad terms, and (d) He will always be part of our lives. CONCLUSION Black adolescent mothers have complex relationships with the biological fathers of their children that may include ongoing sexual activity. The intersection of coparenting and sexual health needs among adolescent mothers highlights the importance of integrating sexually transmitted infections prevention with perinatal health programs. It is important to consider this unique coparenting relationship when providing risk-reduction counseling to young mothers.
Comparing human papillomavirus vaccine concerns on Twitter: a cross-sectional study of users in Australia, Canada and the UK

Objective Opposition to human papillomavirus (HPV) vaccination is common on social media and has the potential to impact vaccine coverage. This study aims to conduct an international comparison of the proportions of tweets about HPV vaccines that express concerns, the types of concerns expressed and the social connections among users posting about HPV vaccines in Australia, Canada and the UK. Design Using a cross-sectional design, an international comparison of English language tweets about HPV vaccines and social connections among Twitter users posting about HPV vaccines between January 2014 and April 2016 was conducted. The Health Belief Model, one of the most widely used theories in health psychology, was used as the basis for coding the types of HPV vaccine concerns expressed on Twitter. Setting The content of tweets and the social connections between users who posted tweets about HPV vaccines from Australia, Canada and the UK. Population 16 789 Twitter users who posted 43 852 tweets about HPV vaccines. Main outcome measures The proportions of tweets expressing concern, the type of concern expressed and the proportions of local and international social connections between users. Results Tweets expressing concerns about HPV vaccines made up 14.9% of tweets in Canada, 19.4% in Australia and 22.6% in the UK. The types of concerns expressed were similar across the three countries, with concerns related to ‘perceived barriers’ being the most common. Users expressing concerns about HPV vaccines in each of the three countries had a relatively high proportion of international followers also expressing concerns. Conclusions The proportions and types of HPV vaccine concerns expressed on Twitter were similar across the three countries. Twitter users who mostly expressed concerns about HPV vaccines were better connected to international users who shared their concerns compared with users who did not express concerns about HPV vaccines.
Enforcing private policy via security-by-Contract

This work aims to investigate how the Security-by-Contract (SxC) paradigm, developed for providing security assurances to mobile applications, can be used for guaranteeing the security of communicating systems composed by several, heterogeneous components. These components need to communicate with each other by establishing direct, point to point connections. Direct connections can involve components sharing no common communication protocols and need a suitable interface. Enablers are in charge of providing these communication interfaces. Each component has a local security policy composed by a public and a private part. When a communication between two components has to be established, each component asks the enabler for providing a communication interface that respects its public policy. We exploit the Security-by-Contract approach for assuring that the application implementing the communication interface is always safe, i.e., it satisfies the security policies setted by components. Moreover, we present an extension of the Security-by-Contract for dealing with trust. Trust management is useful when one of the involved actors is considered to be potentially untrusted and the others want to measure its trust level.
The Genetic Control of Human Ia Alloantigens: A Three‐Loci Model Derived from the Immunochemical Analysis of ‘Supertypic’ Specificities

The complexity ofthe HLA system derives first from the presence of different genes which control similar molecular species and are in close linkage; they probably resulted from gene duplication. Secondly, the complexity derives from the high polymorphism at each locus with multiple-site interallelic differences. A third level of complexity, which is a combination of the first two, is the linkage disequilibrium which preferentially ties some alleles of a locus to some aileles at another locus. This challenging complexity has been attacked by the collaborative efforts of a large number of laboratories over the last 20 years. A large pool of knowledge of the mechanisms of graft rejection, of susceptibility to a number of diseases, and of the immune response in general has resulted from this massive investigation. The classical approach, which is still the core of HLA research, has been the serological study at the cellular level of the alloantigenic specificities possessed by the HLA products; this has been done mainly by the complement-dependent lymphocytotoxicity assay. Through the International Histocompatibility Workshops, this approach led to the recognition of'clusters' of antisera with similar reactivity patterns, thus operationally defining 'antigens'. These antigens were then assigned to different loci, of which genetic distances were determined. Allele frequency in different populations and linkage disequilibrium relationships between alleles at different loci were also defined.
Modelling Complex Resource Requirements in Business Process Management Systems

Real-world business processes are resource-intensive. In work environments human resources usually multitask, both human and non-human resources are typically shared between tasks, and multiple resources are sometimes necessary to undertake a single task. However, current Business Process Management Systems focus on task-resource allocation in terms of individual human resources only and lack support for a full spectrum of resource classes (e.g., human or non-human, application or non-application, individual or teamwork, schedulable or unschedulable) that could contribute to tasks within a business process. In this paper we develop a conceptual data model of resources that takes into account the various resource classes and their interactions. The resulting conceptual resource model is validated using a real-life healthcare scenario.
A Generalized Conflict-Free Memory Addressing Scheme for Continuous-Flow Parallel-Processing FFT Processors With Rescheduling

This paper presents a generalized conflict-free memory addressing scheme for memory-based fast Fourier transform (FFT) processors with parallel arithmetic processing units made up of radix-2q multi-path delay commutator (MDC). The proposed addressing scheme considers the continuous-flow operation with minimum shared memory requirements. To improve throughput, parallel high-radix processing units are employed. We prove that the solution to non-conflict memory access satisfying the constraints of the continuous-flow, variable-size, higher-radix, and parallel-processing operations indeed exists. In addition, a rescheduling technique for twiddle-factor multiplication is developed to reduce hardware complexity and to enhance hardware efficiency. From the results, we can see that the proposed processor has high utilization and efficiency to support flexible configurability for various FFT sizes with fewer computation cycles than the conventional radix-2/radix-4 memory-based FFT processors.
Detection of a Transient R292K Mutation in Influenza A/H3N2 Viruses Shed for Several Weeks by an Immunocompromised Patient

ABSTRACT We describe the case of an immunocompromised patient, positive for influenza A virus (H3N2), in whom the neuraminidase R292K mutation was transiently detected during oseltamivir treatment. The R292K mutation was identified by direct testing in 3 of 11 respiratory specimens collected throughout the patient's illness but in none of the cultures from those specimens.
Development and validation of a health literacy measure for limited literacy public sector patients in South Africa

The growing complexity of healthcare demands greater patient involvement and skills to navigate this complex system. It has therefore become increasingly important to identify individuals with inadequate health literacy, by using efficient, short and reliable measures for doing so. Most research on the development and validation of health literacy tests has been conducted in high-income countries, with very little reported from low-and middle-income countries (LMICs). Existing health literacy measures have come under scrutiny for their lack of cultural sensitivity, bias towards certain population groups and failure to acknowledge health literacy as a multidimensional concept. These measures usually have limited application in LMICs due to the significantly different structuring of healthcare systems, they overlook the extreme discrepancies in educational levels, and rely too heavily on the ability to read health information. No health literacy data for South Africa are available, and only a few health literacy-based research papers have been published in this country. The aim of the study was to develop and validate a health literacy measure that is contextually and culturally appropriate to measure health literacy in limited literacy public sector patients in South Africa. An Item Bank of 30 questions was developed with the input of a diverse expert consultant panel, and included skills-based and self-reported questions which ensured cultural, contextual and educational level appropriateness. The Information and Support for Health Actions Questionnaire (ISHA-Q) is a health literacy measure developed to assess health literacy for LMICs which includes 14 core scales. These were useful in ensuring coverage of a range of health literacy constructs within the Item Bank. The 30 questions were then allocated to one of three health literacy domains: Procedural knowledge, Factual knowledge and Access to healthcare, health services and social support. Ethical approval for the study was obtained. The questions were translated into isiXhosa and underwent pilot testing. Following pilot testing, 120 isiXhosa first-language speakers, at least 18 years old, who attended public sector facilities and had a maximum 12 years of education were recruited from a primary healthcare clinic in Grahamstown. An interpreter was trained and he participated in all interviews. A questionnaire was used to collect data on the 30-

The “Surgeon on Service” Model for Timely, Economically Viable Inpatient Care of Tracheostomy Patients in Academic Pediatric Otolaryngology

Importance The traditional practice model for pediatric otolaryngologists at high-volume academic centers is to simultaneously balance outpatient care responsibilities with those of the inpatient service, emergency department, and ambulatory care clinics. This model leads to challenges with care coordination, timeliness of nonemergency operative care, and consistent participation in care and consultation at the attending surgeon level. The “surgeon on service” (SOS) model—where faculty members rotate to manage the inpatient service in lieu of outpatient responsibilities—has been described as one method to address this conundrum. The operational and economic feasibility of the SOS model has been demonstrated; however, its impact on care coordination, time from consultation to surgical care, and length of stay (LOS) have not been evaluated. Objective To determine the impact of the SOS model on the quality principles of timeliness and efficiency of tracheostomy tube placement and to determine if the SOS model is fiscally feasible in an academic pediatric otolaryngology practice. Design, Setting, and Participants Medical record review of patients undergoing tracheostomy in a pediatric academic medical center and survey of their treating physician trainees, comparing the 6-month SOS pilot phase (postimplementation, January-June 2016) with the 6-month preimplementation period (January-June 2015). Intervention Implementation of the SOS model. Main Outcomes and Measures Time to tracheostomy, frequency of successful coordination of tracheostomy with gastrostomy tube placement, total LOS, productivity measured in work relative value units, and responses to trainee surveys. Results Of the 41 patients included in the study (24 boys and 17 girls; mean age, 3 years; range, 3 months to 17 years), 15 were treated before SOS implementation, and 26 after. Also included were 21 trainees. Before SOS implementation, median time to tracheostomy was 7 days (range, 2-20 days); after SOS implementation, it was 4 days (range, 1-10 days) (difference between the medians, before to after, −3 days; 95% CI, −5 to 0 days). There was no significant difference in overall LOS or ability to coordinate tracheostomy with gastrostomy tube placement. Preimplementation trainee surveys cited dissatisfaction with the communication channels to the primary team when the consulting surgeon was not immediately available to perform tracheostomy. No challenges were reported after implementation. Productivity was comparable to that in the outpatient setting. Conclusions and Relevance In this study, the presence of a rotating inpatient pediatric otolaryngologist was a productive approach to patient care associated with more timely performance of tracheostomy. Other benefits were an improved balance of service with education to trainees and a better perception of communication with consulting services.
