SOA Using AOP for Sensor Web Architecture

Sensor network applications are executed in diverse scenarios, different platforms and in an uncontrolled environment. The data aggregation and then handling the data at the middleware demands an approach to integrate functionalities of various interests from diverse network clusters. So instead of a proprietary solution for individual problems, it is desirable to have a platform independent service oriented architecture. SOA is composed of interactive web services called by client applications. Secured access and use of web services is a primary requirement in these applications. From software engineering point of view, authentication and logging are the cross cutting concerns for the web services. Instead of using conventional object oriented approach for handling concerns in every classs or method, we propose use of Aspect oriented programming paradigm to reduce the code overhead of the system.
Compulsive Cybersex: The New Tea Room

Abstract Cybersex has become the new tea room for meeting anonymous partners and engaging in a fantasy world in which survivors of childhood abuse escape the demands of daily life as well as the pain and shame of past trauma. Compulsive cybersex was described as a survival mechanism involving dissociative reenactment and affect regulation. Descriptive data from a clinical population of cybersex abusers were reviewed to construct four subtypes of cybersex addiction. Treatment strategies for each of the subtypes were recommended.
Delay distribution dependent output feedback stabilization criteria for discrete-time systems with interval time-varying delay

In this paper, we study the delay distribution dependent output-feedback stabilization problem for discrete-time systems with interval time-varying delay. By dividing the delay interval into two subintervals, we construct the corresponding Lyapunov functional. Then by allowing the difference of Lyapunov functional has positive upper bound for the value of time delay in one subinterval, we get corresponding delay distribution dependent output-feedback stabilization criteria. Finally numerical example is given to show the effectiveness of the proposed method.
Improvement of the MR imaging behavior of vascular implants

Vascular implants can cause significant MR image artifacts due to the material (susceptibility artifact) or the electromagnetic characteristics (RF artifact). These artifacts are caused by the distortion of the magnetic field and interferences with the radio frequency (RF) waves of the MR imaging process. Void or complete vanishing of signals occurs in close proximity or inside implants. The artifacts can be minimized by using a material with low magnetic susceptibility and a design of the implant which avoids electrical conductive loops. But not all designs can be made loop‐free and non conductive. A resonant circuit tuned to the Larmor frequency of the MR tomography overcomes the RF artifact and thus improves the visualization of the implant lumen. The paper reviews the state‐of‐the‐art technology of the MR‐signal improvement in implants lumen, with particular regard to the use of resonant circuits such as stents or Vena Cava Filter (VCF), with resonators in 1.0 Tesla and 1.5Tesla MRT.
Distinct Early Molecular Responses to Mutations Causing vLINCL and JNCL Presage ATP Synthase Subunit C Accumulation in Cerebellar Cells

Variant late-infantile neuronal ceroid lipofuscinosis (vLINCL), caused by CLN6 mutation, and juvenile neuronal ceroid lipofuscinosis (JNCL), caused by CLN3 mutation, share clinical and pathological features, including lysosomal accumulation of mitochondrial ATP synthase subunit c, but the unrelated CLN6 and CLN3 genes may initiate disease via similar or distinct cellular processes. To gain insight into the NCL pathways, we established murine wild-type and CbCln6 nclf/nclf cerebellar cells and compared them to wild-type and CbCln3 Δex7/8/Δex7/8 cerebellar cells. CbCln6 nclf/nclf cells and CbCln3 Δex7/8/Δex7/8 cells both displayed abnormally elongated mitochondria and reduced cellular ATP levels and, as cells aged to confluence, exhibited accumulation of subunit c protein in Lamp 1-positive organelles. However, at sub-confluence, endoplasmic reticulum PDI immunostain was decreased only in CbCln6 nclf/nclf cells, while fluid-phase endocytosis and LysoTracker® labeled vesicles were decreased in both CbCln6 nclf/nclf and CbCln3 Δex7/8/Δex7/8 cells, though only the latter cells exhibited abnormal vesicle subcellular distribution. Furthermore, unbiased gene expression analyses revealed only partial overlap in the cerebellar cell genes and pathways that were altered by the Cln3 Δex7/8 and Cln6 nclf mutations. Thus, these data support the hypothesis that CLN6 and CLN3 mutations trigger distinct processes that converge on a shared pathway, which is responsible for proper subunit c protein turnover and neuronal cell survival.
Properties of pentazocine as a discriminative stimulus in the squirrel monkey.

Squirrel monkeys were trained to discriminate i.m. injections of pentazocine (3.0 mg/kg) from vehicle. Stimulus control was considered to have been established when the monkeys reliably completed at least 22 of the 25 trials (i.e. 88%) on the appropriate lever in both pentazocine and vehicle sessions. In cross-generalization tests, two groups of drugs were shown to produce pentazocine-like discriminative effects: 1) the pure opiate agonists morphine, levorphanol and levomethorphan and 2) cyclazocine, phencyclidine and dextrorphan, drugs previously shown to have common discriminative effects. In addition, l-pentazocine proved to be about twice as potent as the racemic mixture. Butorphanol, SKF 10,047 and dextromethorphan produced pentazocine-appropriate responding in 80% of the trials, whereas ketocyclazocine, ethylketocyclazocine and nalbuphine produced less than 50% pentazocine-appropriate responding. Four nonopioid drugs from a variety of pharmacologic classes (apomorphine, d-amphetamine, secobarbital and mescaline) failed to show any discriminative properties in common with pentazocine. In antagonism studies, naltrexone completely blocked the discriminative effects of pentazocine, whereas haloperidol produced only a partial blockade. The discriminative effects of l-pentazocine and levorphanol could also be antagonized by naltrexone, but those of dextrorphan could not. The results suggest the pentazocine has both a morphine-like component of action and a component shared with the nonmorphine-like opioids.
Biological Markers in Alzheimer's Disease

abstract Biomarkers are required to improve our diagnostic sensitivity and specificity and to monitor the biological activity of the Alzheimer’s disease (AD) in terms of the burden of neural involvement and the tempo of disease progression. Biomarkers will initially supplement our more traditional neuropsychological and imaging markers but may eventually evolve into useful surrogate endpoints in AD research. These markers may also provide important mechanistic clues to the pharmacological action of anti-dementia compounds. At this point, the combination of elevated cerebrospinal fluid phosphorylated TAU (CSF p-TAU) proteins and low CSF A²1-42 are the only biomarkers with the sensitivity and specificity to serve as useful diagnostic biomarkers capable of distinguishing AD from other dementias in the early stages. Advances in non CSF tests is urgently required. Markers assessing the progression of disease do not necessarily require the same high disease specificity as diagnostic markers, but need to be sensitive to changes in disease state. At present, candidate markers fall under four main biological rationales: 1. Specific markers of AD neuropathology; 2. Non-specific markers of neural degeneration; 3. Markers of oxidative stress; 4. Markers of neural inflammation. It is foreseeable that a panel of such markers might prove advantageous. It will be important to develop “non-invasive “ markers utilizing readily obtainable tissue samples such as serum or urine to monitor disease progression (or hopefully regression). Repeated sampling would allow for comparison with traditional neuropsychological and imaging measures. The assays themselves will need to be reproducible, reliable and relatively inexpensive. Unfortunately, these biomarkers are in the formative stages of testing and results at present are inconclusive. To facilitate biomarker development in the future it would be highly advantageous to begin to collect and store biological specimens as an adjunct to current research in AD.
Genetic advances in craniosynostosis

Craniosynostosis, the premature ossification of one or more skull sutures, is a clinically and genetically heterogeneous congenital anomaly affecting approximately one in 2,500 live births. In most cases, it occurs as an isolated congenital anomaly, that is, nonsyndromic craniosynostosis (NCS), the genetic, and environmental causes of which remain largely unknown. Recent data suggest that, at least some of the midline NCS cases may be explained by two loci inheritance. In approximately 25–30% of patients, craniosynostosis presents as a feature of a genetic syndrome due to chromosomal defects or mutations in genes within interconnected signaling pathways. The aim of this review is to provide a detailed and comprehensive update on the genetic and environmental factors associated with NCS, integrating the scientific findings achieved during the last decade. Focus on the neurodevelopmental, imaging, and treatment aspects of NCS is also provided.
Audit activity and quality of completed audit projects in primary care in Staffordshire.

OBJECTIVES--To survey audit activity in primary care and determine which practice factors are associated with completed audit; to survey the quality of completed audit projects. DESIGN--From April 1992 to June 1993 a team from the medical audit advisory group visited all general practices; a research assistant visited each practice to study the best audit project. Data were collected in structured interviews. SETTING--Staffordshire, United Kingdom. SUBJECTS--All 189 general practices. MAIN MEASURES--Audit activity using Oxford classification system. Quality of best audit project by assessing choice of topic; participation of practice staff; setting of standards; methods of data collection and presentation of results; whether a plan to make changes resulted from the audit; and whether changes led to the set standards being achieved. RESULTS--Audit information was available from 169 practices (89%). 44(26%) practices had carried out at least one full audit; 40(24%) had not started audit. Mean scores with the Oxford classification system were significantly higher with the presence of a practice manager (2.7(95% confidence interval 2.4 to 2.9) v 1.2(0.7 to 1.8), p < 0.0001) and with computerisation (2.8(2.5 to 3.1) v 1.4 (0.9 to 2.0), p < 0.0001), organised notes (2.6(2.1 to 3.0) v 1.7(7.2 to 2.2), p = 0.03), being a training practice (3.5(3.2 to 3.8) v 2.1(1.8 to 2.4), p < 0.0001), and being a partnership (2.8(2.6 to 3.0) v 1.5(1.1 to 2.0), p < 0.0001). Standards had been set in 62 of the 71 projects reviewed. Data were collected prospectively in 36 projects and retrospectively in 35. 16 projects entailed taking samples from a study population and 55 from the whole population. 50 projects had a written summary. Performance was less than the standards set or expected in 56 projects. 62 practices made changes as a result of the audit. 35 of the 53 that had reviewed the changes found that the original standards had been reached. CONCLUSIONS--Evaluation of audit in primary care should include evaluation of the methods used, whether deficiencies were identified, and whether changes were implemented to resolve any problems found.
Classification and Retrieval of Biomedical Literatures: SNUMedinfo at CLEF QA track BioASQ 2014

This paper describes the participation of the SNUMedinfo team at the BioASQ Task 2a and Task 2b of CLEF 2014 Question Answering track. Task 2a was about biomedical semantic indexing. We trained SVM classifiers to auto- matically assign relevant MeSH descriptors to the MEDLINE article. Regarding Task 2b biomedical question answering, we participated at the document retrieval subtask in Phase A and the ideal answer generation subtask in Phase B. In the document retrieval task, we mostly experimented with semantic concept-en- riched dependence model and sequential dependence model. Semantic concept- enriched dependence model showed significant improvement over baseline. In the ideal answer generation task, we reformulated task as, given relevant lists of passages, selecting the best ones to build the answer. We applied three heuristic methods.
Where Are They Now? Results of a Career Survey of Library and Information Science Graduates

This paper provides an overview of Workforce Issues in Library and Information Science 1 (WILIS 1), a large scale retrospective career study of graduates of all library and information science (LIS) programs in North Carolina from 1964–2007. The interdisciplinary research team used a multiple methods approach to data collection consisting of a survey of LIS graduates, a survey of administrators of LIS programs, and key informant interviews. This article presents an overview of the study design and methods followed by key results from the survey of graduates. The specific research goals of WILIS 1 were: (1) to gain a comprehensive understanding of the educational, workplace, career, and retention issues facing LIS graduates; (2) to investigate the way in which LIS programs track their graduates and use these data for educational and workforce planning; (3) to explore possibilities for a career tracking model that could be used by all LIS programs in the future; and (4) to disseminate the study results in a manner that would facilitate LIS workforce planning. WILIS 1 has now been joined by a second study known as WILIS 2, which is further developing the alumni tracking model that all LIS programs can potentially use.
The Effects of Anticipated Informational and Normative Influence on Perceptions of Hypothetical Opinion Change

Two experiments addressed the role of anticipated informational or normative influence on perceptions of hypothetical opinion change in the context of either an intellective or judgmental task. The findings from Experiment 1 indicate that informational and normative influence processes are perceived as being differentially effective in changing people's opinions about a judgmental task but not about an intellective task. Experiment 2 explores some possible causes of these findings.
Negation in early German-English Interlanguage: more Valueless Features in the L2 initial state

In Eubank (1993/94), I argued that the apparent syntactic optionality one observes in, for example, the placement of medial adverbs vis-à-vis thematic verbs in French-English Interlanguage can be explained if one assumes that the relevant parametric values of French do not transfer into the English L2 initial state. What one finds instead is a nonvalue of sorts, which I dubbed . In this article, I extend this view of 'Valueless Features' by examining data from Wode (1981) on the L2 acquisition of English by speakers of German. In fact, what I show here is that, in spite of important differences between the French-English and the German-English data, Valueless Features extends in a fairly natural way. In addition, however, I also examine two views that differ from Valueless Features, namely, the Full Transfer/Full Access Hypothesis of Schwartz and Sprouse (e.g., 1994) and the Minimal Trees of Vainikka and Young-Scholten (1994). Here, a careful review of the acquisitional data - either the French-English data or the German-English data - suggests that these views may not be as straightforward as they may otherwise appear.
Enteral Tryptophan Requirement Determined by Oxidation of Gastrically or Intravenously Infused Phenylalanine Is Not Different from the Parenteral Requirement in Neonatal Piglets

We have recently shown that the requirements of several amino acids differ substantially when neonates are fed parenterally as opposed to enterally. Our first objective was to determine whether the tryptophan requirement was different in parenterally fed (IVfed/IVdose) versus enterally fed (IGfed/IVdose) piglets. Because of the extensive extraction of amino acids by the gut, our other objective was to determine whether the route of isotope administration [i.e. intragastric (IGfed/IGdose) versus i.v. (IGfed/IVdose) dose] affects the estimate of tryptophan requirement in enterally fed piglets. We used the indicator amino acid oxidation technique in piglets (10 ± 0.5 d old, 2.79 ± 0.28 kg) receiving a complete elemental diet for 6 d either intragastrically or intravenously. Piglets were randomly assigned to receive test diets containing one of seven levels of tryptophan. All animals received a primed, constant infusion of l-[1-14C]phenylalanine either parenterally (IVfed/IVdose and IGfed/IVdose) or enterally (IGfed/IGdose). The mean tryptophan requirements for IVfed/IVdose (0.145 ± 0.023 g/kg/d), IGfed/IVdose (0.127 ± 0.022 g/kg/d), and IGfed/IGdose (0.113 ± 0.024 g/kg/d) were similar as were the safe intakes (upper 95% confidence interval) (0.185, 0.164, 0.154 g/kg/d, respectively). These data indicate that tryptophan is not extensively used by the gut, in contrast to all the other amino acids we have studied. Furthermore, in spite of a splanchnic extraction of 27% of the phenylalanine dose, the route of isotope infusion does not affect the tryptophan requirement as determined by indicator amino acid oxidation.
Reduced gray matter volume in the anterior cingulate, orbitofrontal cortex and thalamus as a function of mild depressive symptoms: a voxel-based morphometric analysis

Background Studies investigating structural brain abnormalities in depression have typically employed a categorical rather than dimensional approach to depression [i.e. comparing subjects with Diagnostic and Statistical Manual of Mental Disorders (DSM)-defined major depressive disorder (MDD) v. healthy controls]. The National Institute of Mental Health, through their Research Domain Criteria initiative, has encouraged a dimensional approach to the study of psychopathology as opposed to an over-reliance on categorical (e.g. DSM-based) diagnostic approaches. Moreover, subthreshold levels of depressive symptoms (i.e. severity levels below DSM criteria) have been found to be associated with a range of negative outcomes, yet have been relatively neglected in neuroimaging research. Method To examine the extent to which depressive symptoms – even at subclinical levels – are linearly related to gray matter volume reductions in theoretically important brain regions, we employed whole-brain voxel-based morphometry in a sample of 54 participants. Results The severity of mild depressive symptoms, even in a subclinical population, was associated with reduced gray matter volume in the orbitofrontal cortex, anterior cingulate, thalamus, superior temporal gyrus/temporal pole and superior frontal gyrus. A conjunction analysis revealed concordance across two separate measures of depression. Conclusions Reduced gray matter volume in theoretically important brain regions can be observed even in a sample that does not meet DSM criteria for MDD, but who nevertheless report relatively elevated levels of depressive symptoms. Overall, these findings highlight the need for additional research using dimensional conceptual and analytic approaches, as well as further investigation of subclinical populations.
Student Passivity During Cooperative Small Groups in Mathematics

Abstract Recent studies of cooperative small-group instruction in mathematics have drawn attention to individual differences in students' responses to the demands and opportunities of that instructional format. In this article, findings of a study (Mulryan, 1989) that investigated fifth- and sixth-grade students' attending and participating behavior in cooperative small groups in mathematics are reported. A major finding of the study was that some students, mainly low achievers, manifested a high level of passive behavior in cooperative small groups. Some possible reasons for passivity among low achievers are suggested, and a categorization of types of passivity in cooperative small groups is provided. Student and teacher perceptions of passivity are also reported, as well as suggestions for further research in this area.
An Efficient High-Dimensional Sparse Fourier Transform

We propose RSFT, which is an extension of the one dimensional Sparse Fourier Transform algorithm to higher dimensions in a way that it can be applied to real, noisy data. The RSFT allows for off-grid frequencies. Furthermore, by incorporating Neyman-Pearson detection, the frequency detection stages in RSFT do not require knowledge of the exact sparsity of the signal and are more robust to noise. We analyze the asymptotic performance of RSFT, and study the computational complexity versus the worst case signal SNR tradeoff. We show that by choosing the proper parameters, the optimal tradeoff can be achieved. We discuss the application of RSFT on short range ubiquitous radar signal processing, and demonstrate its feasibility via simulations.
Vision-Controlled Autonomous Indoor Helicopter

Indoor navigation of aerial vehicles poses several challenges in sustaining hover flights. The key challenges are the high presence of obstacles in constrained environments, frugal payload budget and the need for real-time control response. In this paper, we describe a successful application of computer vision and machine learning techniques for autonomous panning of RC helicopters in fixed indoor settings. Our framework uses images of the environment to ‘learn’ its surrounding and perform attitude estimation on live-streaming data from an onboard wireless camera using the learned model. We then detail the design of our controller, capable of hovering the helicopter in place, sustaining orientation with respect to reference points and following panning trajectories. Finally, we present test results based on simulations and actual autonomous test flights.
A Classification framework for Software Requirements Prioritization Approaches

The task of eliciting requirements has became extremely difficult because stakeholders have different perspectives on an expectation on a system. Besides, the time to obtain the final product is limited. To overcome this situation, a requirements ranking may help in planning releases by indicating which functions are critical and which ones can be added, and in what order, over successive releases. The prioritizing process must hold stakeholder satisfaction considering high-priority requirements first. However, practical experience shows that prioritizing requirements is not as straightforward task as the literature suggests. Considering that, this paper has two goals: the first one is to present a classification framework for software requirements prioritization approaches (emphasizing differences and similarities among eleven selected approaches); and the second one is to show the approaches' weaknesses and to propose possible improvements for future research on this line.
