Reliable, Low Overhead Link Quality Estimation for 802.11 Wireless Mesh Networks

We propose QUEST (QUality ESTimation), a new method that accurately estimates IEEE 802.11 wireless link quality with no in-band signaling overhead. Existing link quality estimation methods either are based on hello exchanges by fixing or varying transmission rates or rely on the history (e.g., delivery ratio) of previously sent data packets in a per-rate/-neighbor manner. QUEST on the other hand, is based on a delivery ratio vs. SNR (Signal to Noise Ratio) relation, called profile, that is managed offline. QUEST estimates the target link quality in terms of delivery ratio by performing profile lookup for any incoming messages including broadcast hello, beacon, data packets, etc. Therefore, it does not depend on a designated protocol to obtain the delivery ratio. Instead, in QUEST, the per-rate/-neighbor management of link quality is achieved by profile lookup. We perform testbed experiments to achieve the profile and also unravel two major bugs in MadWifi driver, widely employed by many researchers to build an 802.11-based system. Utilizing the large database of transmitter and receiver traces with an indigenously developed tool, we study the impact of altering the averaging time period on the profile for different transmission rates.
Structured and Unstructured Reminiscence Training and Depression among the Elderly

One hundred and sixty:two depressed Caucasian elderly were treatment and control subjects for a therapeutic intervention designed to test the efficacy of structured and unstructured reminiscence training for subjects' depression. Pre-and posttreatment measures of depression, ego-strength and self-assessment ratings were obtained. Consistent with hypotheses, a multivariate analysis revealed that subjects trained in structured reminiscence showed significantly greater improvement on the dcpcndent measures than did subjects trained in unstructured reminiscence. Overall, subjects in both structured and unstructured reminiscence conditions reported more improvement than the no-treatment control subjects. Contents of subjects' reminiscence were factor-analysed for sex differences and yielded four factors with high factor loadings. Results of the factor analysis and the effects of the two forms of reminiscence training were discussed in terms of their implications for the treatment of depression in the elderly.
Socially Enhanced Network Address Translation

The rapid evolution of the Internet has forced theuse of Network Address Translation (NAT) to help slow thedecline of publicly available IPv4 address space. While NATprovides the requisite address space as well as privacy andsecurity to its users, it also eliminates the ability to establishincoming connections to devices within a private network.To address this issue, we propose combining social networktopologies with traditional NAT architecture to better integratepeer-to-peer communication through NATed networks. Thissocially enhanced NAT allows incoming connections fromtrusted parties, resolving one of the central criticisms of theNAT approach.
Verifying Web Services Composition based on LTL and colored Petri Net

The main method of model checking based on LTL is constructing a Büchi automata by system model and a Büchi automata equaling with the LTL denied form, and then checking the automata's acceptive language is empty or not. The idea of verifying Web Services Composition is modeling Web Services Composition by Colored Petri Net, and then using the modeling checking technique to verifying the model. It can find the fault occurring in the process of composing Web Services efficiently. Finally, an example of online shopping is used to explain the idea's correctness.
The relationship between sustained attention, attentional selectivity, and capacity

The Theory of Visual Attention (TVA; Bundesen, 1990) provides a quantitative account of visual attentional selectivity and capacity but does not include a parameter relating to sustained attention. We conducted two studies to examine the relationship between sustained attention and the TVA parameters relating to selectivity and capacity. In the first study (n=46; mean age=41, SD=10), we investigated the effects of self alerting during a combined whole and partial report task (CombiTVA). In the second study, 70 participants (aged 20–69), performed the CombiTVA and the Sustained Attention to Response Task (Robertson, Manly, Andrade, Baddeley, & Yiend, 1997). The results indicated that attentional selectivity and capacity were unaffected by self alerting, unrelated to sustained attention ability and robust to the adverse effects of time-on-task. These findings are in keeping with the idea of independent functions relating to sustained attention and attentional selectivity and capacity.
Harmony-guided image editing

While image editing tends to be popularized, it remains a time-consuming task requiring a minimal expertise. This proposal presents an innovative tool for performing guided image editing. Oriented by a quality metric based on color harmony theory, the user picks up the least harmonious color areas and retouches them based on our recommended color palette. This set of proposed colors ensure the maximization of the global color harmony for the considered picture. In few clicks, anyone is able to retouch incongruous colors while respecting his taste or intent.
In vitro models of pancreatic cancer for translational oncology research

Background: Pancreatic cancer is a disease of near uniform fatality and the overwhelming majority of patients succumb to their advanced malignancy in a few months of diagnosis. Despite considerable advances in our understanding of molecular mechanisms underlying pancreatic carcinogenesis, this knowledge has not yet been fully translated into clinically available treatment strategies that yield significant improvements in disease free or overall survival. Objective: Cell line-based in vitro model systems provide powerful tools to identify potential molecular targets for therapeutic intervention as well as for initial preclinical evaluation of novel drug candidates. Here, we provide a brief overview of recent literature on cell line-based model systems of pancreatic cancer and their application in the search for novel therapeutics against this vicious disease. Conclusion: Although in vitro models of pancreatic cancer are of tremendous value for genetic studies and for initial functional screenings in drug discovery, they carry several immanent drawbacks and are often poor in predicting therapeutic response in humans. Therefore, in most instances, they are successfully exploited to generate hypothesis and identify molecular targets for novel therapeutics, which are subsequently subject to further in-depth characterization using more advanced in vivo model systems and clinical trials.
Design considerations of a bearingless motor for high-purity mixing applications

This paper presents how a bearingless motor with exterior rotor can be implemented successfully in high-purity mixing applications. Important design parameters are identified and their influence on the system performance is demonstrated. The mechanical setup, the principle of bearing force and torque generation, the power electronics, the closed-loop control and the cooling concept are introduced in detail. Moreover, design considerations about optimizing the motor performance, the efficiency and the heat distribution are presented. Finally, the performance of the new motor is verified with a laboratory prototype.
Discourses on Text Integrity: Information and Interpretation in the Contested Fallout Knowledge Community

In an effort to further understand the nature of the productive consumption of media fans in an era of digital connectivity, this article expands on Lévy’s (1997) concept of the knowledge community as it applies to fans of the digital-game series Fallout. Lévy proposed that the age of digital-connectivity would usher in knowledge communities where participation was voluntary, aggregate, and democratic. I argue that Baym’s (2000) interpretive and informative practices, which serve as the lynchpins of fan discourse, may be understood as the lynchpins of the knowledge community as well. Further, here interpretive and informative practices are not only used to build community and negotiate values, but also to define status and position within the contested Fallout knowledge community. By testing the knowledge community against such an environment, and integrating it into previous research on the role of fan labor in an era where producers are increasingly interested in that labor, this article proposes an understanding of the concept that may well add nuance and context beyond the theory’s utopian roots.
Sanitization and Anonymization of Document Repositories

Information security and privacy in the context of the World Wide Web (WWW) are important issues that are still being investigated. However, most of the present research is dealing with access control and authentication-based trust. Especially with the popularity of WWW as one of the largest information sources, privacy of individuals is now as important as the security of information. In this chapter, our focus is text, which is probably the most frequently seen data type in the WWW. Our aim is to highlight the possible threats to privacy that exist due to the availability of document repositories and sophisticated tools to browseand analyze these documents. We first identify possible threats to privacy in document repositories. We then discuss a measure for privacy in documents with some possible solutions to avoid or, at least, alleviate these threats.
Design and evaluation of an interactive visualization of therapy plans and patient data

CareCruiser is a system designed to visualize the effects of applying clinical treatment plans and to support the exploration of the effects that the treatments have on the patient's condition. While considerable progress has been made in recent years concerning the visualization methods to support computer-executable clinical treatment plans, our prototype succeeds in combining and enhancing the possibilities offered by the features of other systems. To ensure the quality of our visualization (1) we collaborated with a medical expert in an early design phase, (2) we conducted a heuristic usability evaluation, and (3) we tested its usefulness with domain experts. In the course of the usability evaluation the evaluators tested the prototype in conformance with generally accepted usability principles; in the user testing, physicians were asked to function as users and were interviewed afterwards. Both the usability evaluation and the user testing led to useful results and presented a very positive picture of the visualization and the exploration features of CareCruiser.
MSOAR: A High-Throughput Ortholog Assignment System Based on Genome Rearrangement

The assignment of orthologous genes between a pair of genomes is a fundamental and challenging problem in comparative genomics, since many computational methods for solving various biological problems critically rely on bona fide orthologs as input. While it is usually done using sequence similarity search, we recently proposed a new combinatorial approach that combines sequence similarity and genome rearrangement. This paper continues the development of the approach and unites genome rearrangement events and (post-speciation) duplication events in a single framework under the parsimony principle. In this framework, orthologous genes are assumed to correspond to each other in the most parsimonious evolutionary scenario involving both genome rearrangement and (post-speciation) gene duplication. Besides several original algorithmic contributions, the enhanced method allows for the detection of inparalogs. Following this approach, we have implemented a high-throughput system for ortholog assignment on a genome scale, called MSOAR, and applied it to human and mouse genomes. As the result will show, MSOAR is able to find 99 more true orthologs than the INPARANOID program did. In comparison to the iterated exemplar algorithm on simulated data, MSOAR performed favorably in terms of assignment accuracy. We also validated our predicted main ortholog pairs between human and mouse using public ortholog assignment datasets, synteny information, and gene function classification. These test results indicate that our approach is very promising for genome-wide ortholog assignment. Supplemental material and MSOAR program are available at http://msoar.cs. ucr.edu.
Can they recover? An assessment of adult adjustment problems among males in the abstainer, recovery, life-course persistent, and adolescence-limited pathways followed up to age 56 in the Cambridge Study in Delinquent Development

Abstract Much research has examined Moffitt's developmental taxonomy, focusing almost exclusively on the distinction between life-course persistent and adolescence-limited offenders. Of interest, a handful of studies have identified a group of individuals whose early childhood years were marked by extensive antisocial behavior but who seemed to recover and desist (at least from severe offending) in adolescence and early adulthood. We use data from the Cambridge Study in Delinquent Development to examine the adult adjustment outcomes of different groups of offenders, including a recoveries group, in late middle adulthood, offering the most comprehensive investigation of this particular group to date. Findings indicate that abstainers comprise the largest group of males followed by adolescence-limited offenders, recoveries, and life-course persistent offenders. Furthermore, the results reveal that a host of adult adjustment problems measured at ages 32 and 48 in a number of life-course domains are differentially distributed across these four offender groups. In addition, the recoveries and life-course persistent offenders often show the greatest number of adult adjustment problems relative to the adolescence-limited offenders and abstainers.
Organisational Factors, Job Satisfaction and Intention to Leave Among Newly Qualified Social Workers in England

Satisfaction with different organisational elements and aspects of work contributes markedly to overall levels of job satisfaction and intention to leave. For newly qualified social workers (NQSWs), especially immediately after graduation, self-perceived competence and their confidence in their educational preparation are also important. This article reports on a longitudinal study following 280 social work students into social work employment in England using data collected as students and six months after graduation. We focus on their experiences as NQSWs, thus only including those working in social work jobs, reporting the relative importance of their satisfaction with different work elements, such as supervision and job engagement. These are used to construct a model of NQSWs' overall satisfaction and intentions of leaving their social work jobs. The model incorporates NQSWs' perceptions of how well their degree courses prepared them for their current social work jobs in addition to personal, organisational and specific role characteristics. Using statistical techniques of factor analysis and regression modelling we highlight the complexities of how job satisfaction is constructed and we argue that the data reveal the importance of team support and self-efficacy in relation to whether social workers are thinking about leaving their current social work jobs.

MxA as a clinically applicable biomarker for identifying systemic interferon type I in primary Sjögren's syndrome

Objective To establish an easy and practical assay for identifying systemic interferon (IFN) type I bioactivity in patients with primary Sjögren's syndrome (pSS). The IFN type I signature is present in over half of the pSS patients and identifies a subgroup with a higher disease activity. This signature is currently assessed via laborious expression profiles of multiple IFN type I-inducible genes. Methods In a cohort of 35 pSS patients, myxovirus-resistance protein A (MxA) was assessed as a potential biomarker for type I IFN activity, using an enzyme immunoassay (EIA) on whole-blood and flow cytometric analyses (fluorescence-activated cell sorting, FACS) of isolated CD14 monocytes. In addition, potential biomarkers such as CD64, CD169 and B cell-activating factor (BAFF) were simultaneously analysed in CD14 monocytes using FACS. The IFNscore, a measure for total type I IFN bioactivity, was calculated using expression values of the IFN type I signature genes—IFI44, IFI44L, IFIT3, LY6E and MX1—in CD14 monocytes, determined by real-time quantitative PCR. Results IFNscores correlated the strongest with monocyte MxA protein (r=0.741, p<0.001) and whole-blood MxA levels (r=0.764, p<0.001), weaker with CD169 (r=0.495, p<0.001) and CD64 (r=0.436, p=0.007), and not at all with BAFF protein. In particular, whole blood MxA levels correlated with EULAR Sjögren's Syndrome Disease Activity Index scores and numerous clinical pSS parameters. Interestingly, patients on hydroxychloroquine showed reduced MxA levels (EIA, p=0.04; FACS p=0.001). Conclusions The MxA assays were excellent tools to assess IFN type I activity in pSS, MxA-EIA being the most practical. MxA levels associate with features of active disease and are reduced in hydroxychloroquine-treated patients, suggesting the clinical applicability of MxA in stratifying patients according to IFN positivity.
Brief Bipolar Markers for the Five Factor Model of Personality

The initial development of a brief 30-item bipolar rating scale designed to measure the Five Factor Model of personality is presented. This scale assesses Factor V as a variant of Openness rather than Intellect. Factor analyses across five samples (Total N = 898) indicated that the trait-term pairs used to construct the scales exhibited relatively high univocal factor loadings (M = .62, SD=.13) and acceptable values of internal consistency (M α=.79, SD= 07)
A Mediation Model of Air Travelers’ Voluntary Climate Action

This study developed a behavioral model of intentions to purchase aviation carbon offsets, and tested the model through structural equation models. The model draws on the established hierarchical models of human behavior to hypothesize relationships between general and specific attitudes as predictors of offsetting intentions. The New Ecological Paradigm scale, the theory of planned behavior and variables from past literature were employed to measure general environmental attitudes, intermediate beliefs, and behavior-specific attitudes and norms. The current research represents a first attempt to build a theoretical model that helps to understand the relationships between factors that determine whether people will purchase aviation carbon offsets. The results show that a more positive orientation toward the environment could be an important predictor of environmental intentions operating both directly on intentions as well as guiding beliefs that relate to intentions. Policy implications of the findings are discussed, encouraging greater voluntary climate action.
Subjective health complaints: Is coping more important than control?

The influence of psychological demands in a work situation on subjective health complaints has been investigated. A demand/coping model has been developed and compared with the traditional demand}control model. The new model is based on the notion that all stressors (loads) are filtered by coping (positive response outcome expectancies) and defence mechanisms (stimulus distortion) before they gain access to the response system. A total of 1060 employees (401 men and 659 women) working in the Norwegian postal service filled out questionnaires on psychological demands, control, coping (Utrecht Coping List), job stress, and subjective health complaints (Subjective Health Complaint Inventory). Subjective health complaints were found to depend more on combinations of demands and coping than on demands and control. Individuals with high demands/low coping had most health problems, and those with low demands}high coping had the lowest level. Individuals with high demands/high coping had high reports of job stres.
Accumulation of the sigma‐1 receptor is common to neuronal nuclear inclusions in various neurodegenerative diseases

The sigma‐1 receptor (SIGMAR1) is now known to be one of the endoplasmic reticulum (ER) chaperones, which participate in the degradation of misfolded proteins in cells via the ER‐related degradation machinery linked to the ubiquitin‐proteasome pathway. Mutations of the SIGMAR1 gene are implicated in the pathogenesis of familial frontotemporal lobar degeneration and motor neuron disease. Involvement of ER dysfunction in the formation of inclusion bodies in various neurodegenerative diseases has also become evident. We performed immunohistochemical staining to clarify the localization of SIGMAR1 in the brains of patients with neurodegenerative disorders, including trans‐activation response DNA protein 43 (TDP‐43) proteinopathy, tauopathy, α‐synucleinopathy, polyglutamine disease and intranuclear inclusion body disease (INIBD). Double‐immunocytofluorescence and Western blot analyses of cultured cells were also performed to investigate the role of SIGMAR1 using a specific exportin 1 inhibitor, leptomycin B and an ER stress inducer, thapsigargin. SIGMAR1 was consistently shown to be co‐localized with neuronal nuclear inclusions in TDP‐43 proteinopathy, five polyglutamine diseases and INIBD, as well as in intranuclear Marinesco bodies in aged normal controls. Cytoplasmic inclusions in neurons and glial cells were unreactive for SIGMAR1. In cultured cells, immunocytofluorescent study showed that leptomycin B and thapsigargin were shown to sequester SIGMAR1 within the nucleus, acting together with p62. This finding was also supported by immunoblot analysis. These results indicate that SIGMAR1 might shuttle between the nucleus and the cytoplasm. Neurodegenerative diseases characterized by neuronal nuclear inclusions might utilize the ER‐related degradation machinery as a common pathway for the degradation of aberrant proteins.
