Blackboard-based software framework and tool for mobile device context awareness

The usage needs of a mobile device vary according to context. Mobile context awareness research aims at providing the device user with a way of usage that suits the situation. Interaction based on context requires acquiring, abstracting and delivering information from multiple sources, such as sensors, to the application or application control. A generic software framework and tool for facilitating the rapid development of mobile device context-aware applications were developed in this work. The blackboard-based framework supports all tasks that are required for context-based application control, where contexts can be any events that are relevant to user interaction with the application, including explicit inputs. The core component of the framework, Context Manager, provides a publish and subscribe mechanism and a database for the applications and application control. The framework provides an application programming interface (API) for developers. As a higher abstraction-level programming interface, a customization tool enables easy end-user development of contextaware features into existing applications without changing them. An extensible ontology is used as a uniform context representation within the framework. The purpose of the ontology, together with the API, is to enable easy access, use and reuse of human-understandable context information. Context information sources, such as sensors, often produce a continuous stream of low abstraction-level data. The framework supports the transformation of a continuous data stream into abstracted context events, described in the ontology. Context information is delivered to applications or application control as abstracted events. The main result of the dissertation is a software framework, ontology and tool, which facilitate the customization of sensor-based humancomputer interaction in mobile devices. The practical applicability, scope, and computational efficiency of the implemented framework and customization tool are evaluated with performance measurements and multiple applications implemented in a mobile phone with real sensor sources.
Introduction to behavioral addictions.

BACKGROUND
Several behaviors, besides psychoactive substance ingestion, produce short-term reward that may engender persistent behavior, despite knowledge of adverse consequences, i.e., diminished control over the behavior. These disorders have historically been conceptualized in several ways. One view posits these disorders as lying along an impulsive-compulsive spectrum, with some classified as impulse control disorders. An alternate, but not mutually exclusive, conceptualization considers the disorders as non-substance or "behavioral" addictions.


OBJECTIVES
Inform the discussion on the relationship between psychoactive substance and behavioral addictions.


METHODS
We review data illustrating similarities and differences between impulse control disorders or behavioral addictions and substance addictions. This topic is particularly relevant to the optimal classification of these disorders in the forthcoming fifth edition of the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders (DSM-V).


RESULTS
Growing evidence suggests that behavioral addictions resemble substance addictions in many domains, including natural history, phenomenology, tolerance, comorbidity, overlapping genetic contribution, neurobiological mechanisms, and response to treatment, supporting the DSM-V Task Force proposed new category of Addiction and Related Disorders encompassing both substance use disorders and non-substance addictions. Current data suggest that this combined category may be appropriate for pathological gambling and a few other better studied behavioral addictions, e.g., Internet addiction. There is currently insufficient data to justify any classification of other proposed behavioral addictions.


CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE
Proper categorization of behavioral addictions or impulse control disorders has substantial implications for the development of improved prevention and treatment strategies.
Lip Reading in Profile

There has been a quantum leap in the performance of automated lip reading recently due to the application of neural network sequence models trained on a very large corpus of aligned text and face videos. However, this advance has only been demonstrated for frontal or near frontal faces, and so the question remains: can lips be read in profile to the same standard? The objective of this paper is to answer that question. We make three contributions: first, we obtain a new large aligned training corpus that contains profile faces, and select these using a face pose regressor network; second, we propose a curriculum learning procedure that is able to extend SyncNet [10] (a network to synchronize face movements and speech) progressively from frontal to profile faces; third, we demonstrate lip reading in profile for unseen videos. The trained model is evaluated on a held out test set, and is also shown to far surpass the state of the art on the OuluVS2 multi-view benchmark.
Association between endogenous complement inhibitor and myocardial salvage in patients with myocardial infarction.

BACKGROUND
Many pathogenic processes and diseases are the result of an erroneous activation of the complement cascade and a number of inhibitors of complement have thus been examined for anti-inflammatory actions. It was recently demonstrated that supraphysiological concentrations of the endogenous complement inhibitor MAp44 (also denoted MAP1) protect against myocardial reperfusion injury. In the present study, we examined the association between outcome after acute myocardial infarction (MI) and the plasma levels of MAp44 and its related proteins MASP-1 and MASP-3 in patients with first-time MI. In addition, we compared plasma levels of MAp44, MASP-1, and MASP-3 in MI patients to levels in a healthy control group.


METHODS
A total of 192 MI patients and 140 control persons were included. Plasma samples were obtained and analysed with time-resolved immunofluorometric assays determining the plasma levels of MAp44, MASP-1, and MASP-3. The myocardial outcomes (salvage index and final infarct size) were measured by gated single-photon emission CT.


RESULTS
MI patients had 18 % higher plasma levels of MAp44 (IQR 11-25%) as compared to the healthy control group (p<0.001. However, neither salvage index (Spearman rho -0.1, p=0.28) nor final infarct size (Spearman rho 0.02, p=0.83) correlated with plasma levels of MAp44. Likewise, MASP-1 and MASP-3 were elevated in MI patients (p=0.002 and p<0.001), but the levels were not correlated to outcome.


CONCLUSIONS
Plasma levels of MAp44, MASP-1, and MASP-3 are significantly higher in patients with MI compared to healthy control persons, but are not associated with short-term outcome measured as salvage index and final infarct.
Survival and complication rates of implant-supported fixed partial dentures with cantilevers: a systematic review.

OBJECTIVE
The objective of the present systematic review was to analyze the potential effect of incorporation of cantilever extensions on the survival rate of implant-supported fixed partial dental prostheses (FPDPs) and the incidence of technical and biological complications, as reported in longitudinal studies with at least 5 years of follow-up.


METHODS
A MEDLINE search was conducted up to and including November 2008 for longitudinal studies with a mean follow-up period of at least 5 years. Two reviewers performed screening and data abstraction independently. Prosthesis-based data on survival/failure rate, technical complications (prosthesis-related problems, implant loss) and biological complications (marginal bone loss) were analyzed.


RESULTS
The search provided 103 titles with abstract. Full-text analysis was performed of 12 articles, out of which three were finally included. Two of the studies had a prospective or retrospective case-control design, whereas the third was a prospective cohort study. The 5-year survival rate of cantilever FPDPs varied between 89.9% and 92.7% (weighted mean 91.9%), with implant fracture as the main cause for failures. The corresponding survival rate for FPDPs without cantilever extensions was 96.3-96.2% (weighted mean 95.8%). Technical complications related to the supra-constructions in the three included studies were reported to occur at a frequency of 13-26% (weighted mean 20.3%) for cantilever FPDPs compared with 0-12% (9.7%) for non-cantilever FPDPs. The most common complications were minor porcelain fractures and bridge-screw loosening. For cantilever FPDPs, the 5-year event-free survival rate varied between 66.7% and 79.2% (weighted mean 71.7%) and between 83.1% and 96.3% (weighted mean 85.9%) for non-cantilever FPDPs. No statistically significant differences were reported with regard to peri-implant bone-level change between the two prosthetic groups, either at the prosthesis or at the implant level.


CONCLUSION
Data on implant-supported FPDPs with cantilever extensions are limited and therefore survival and complication rates should be interpreted with caution. The incorporation of cantilevers into implant-borne prostheses may be associated with a higher incidence of minor technical complications.
Evaluation of a quality improvement collaborative in asthma care: does it improve processes and outcomes of care?

PURPOSE
We wanted to examine whether a collaborative to improve asthma care influences process and outcomes of care in asthmatic adults.


METHOD
We undertook a preintervention-postintervention evaluation of 185 patients in 6 intervention clinics and 3 matched control sites that participated in the Institute for Healthcare Improvement Breakthrough Series (BTS) Collaborative for asthma care. The intervention consisted of 3, 2-day educational sessions for teams dispatched by participating sites, which were followed by 3 action periods during the course of a year.


RESULTS
Overall process of asthma care improved significantly in the intervention compared with the control group (change of 10% vs 1%, P = .003). Patients in the intervention group were more likely to attend educational sessions (20% vs 5%, P = .03). Having a written action plan, setting goals, monitoring peak flow rates, and using long-term asthma medications increased between 2% and 19% (not significant), but asthma-related knowledge was unchanged for the 2 groups. Patients in the BTS Collaborative were significantly more likely to be satisfied with clinician and lay educator communication (62% vs 39%, P = .02). Health-related quality of life, asthma-specific quality of life, number of bed days caused by asthma-related illness, and acute care service use were not significantly different between the 2 groups.


CONCLUSIONS
The intervention was associated with improved process-of-care measures that have been linked with better outcomes. Patients benefited through increased satisfaction with communication. Follow-up of patients who participated in the intervention may have been too brief to be able to detect significant improvement in health-related outcomes.
Relative urgency for referral from primary care to rheumatologists: the Priority Referral Score.

OBJECTIVE
Timely access to rheumatology consultation is fundamental to appropriate and effective management of patients with musculoskeletal and autoimmune diseases. Yet, for a variety of reasons, limited and delayed access is commonplace. Moreover, information exchange for referral is often inadequate or poorly communicated. The objective of this work was to improve referral from primary care to rheumatology by formulating and testing a clinically coherent, reliable, and non-diagnosis-dependent Priority Referral Score (PRS).


METHODS
Using a deliberative process, a clinical panel of 10 primary care providers (PCPs) and rheumatology specialists reviewed clinical case scenarios and engaged in a highly iterative process to develop criteria, definitions, and weights for the PRS, a linear 100-point scale to rate the relative urgency of referral. Following tool formulation, clinicians uninvolved with the process tested the PRS against their clinical judgment.


RESULTS
The PRS comprises 8 criteria, with 2-4 levels for each criterion, and each having a weight generated through conjoint analysis, which forced choices around the comparative urgency of all of the criteria and levels. The PRS showed a strong correlation between clinical rankings of rheumatologists and PCPs in both the deliberative panel, and the physicians subsequently involved in the testing of the PRS.


CONCLUSION
No standardized priority-setting criteria are available for the full range of primary care referrals to rheumatologists. The PRS had face value with panelists and provided acceptable interrater and intrarater reliability when tested with other rheumatologists and PCPs. Pilot testing with other clinicians and in other settings is justified and prerequisite to use in clinical practice.
Effects of handgrip training with venous restriction on brachial artery vasodilation.

UNLABELLED
Previous studies have shown that resistance training with restricted venous blood flow (Kaatsu) results in significant strength gains and muscle hypertrophy. However, few studies have examined the concurrent vascular responses following restrictive venous blood flow training protocols.


PURPOSE
The purpose of this study was to examine the effects of 4 wk of handgrip exercise training, with and without venous restriction, on handgrip strength and brachial artery flow-mediated dilation (BAFMD).


METHODS
Twelve participants (mean +/- SD: age = 22 +/- 1 yr, men = 5, women = 7) completed 4 wk of bilateral handgrip exercise training (duration = 20 min, intensity = 60% of the maximum voluntary contraction, cadence = 15 grips per minute, frequency = three sessions per week). During each session, venous blood flow was restricted in one arm (experimental (EXP) arm) using a pneumatic cuff placed 4 cm proximal to the antecubital fossa and inflated to 80 mm Hg for the duration of each exercise session. The EXP and the control (CON) arms were randomly selected. Handgrip strength was measured using a hydraulic hand dynamometer. Brachial diameters and blood velocity profiles were assessed, using Doppler ultrasonography, before and after 5 min of forearm occlusion (200 mm Hg) before and at the end of the 4-wk exercise.


RESULTS
After exercise training, handgrip strength increased 8.32% (P = 0.05) in the CON arm and 16.17% (P = 0.05) in the EXP arm. BAFMD increased 24.19% (P = 0.0001) in the CON arm and decreased 30.36% (P = 0.0001) in the EXP arm.


CONCLUSIONS
The data indicate handgrip training combined with venous restriction results in superior strength gains but reduced BAFMD compared with the nonrestricted arm.
npn-soft sets theory and their applications

In this paper, we firstly defined neutrosophic parameterized neutrosophic soft sets(npn−soft sets) which is combination of a neutrosophic sets and a soft sets. Our npn−soft sets generalizes the concept of the other soft sets such as; fuzzy soft sets, intuitionistic fuzzy soft sets, neutrosophic soft sets, fuzzy parameterized soft sets, intuitionistic fuzzy parameterized soft sets, neutrosophic parameterized soft sets and so on. Then, we introduce some definitions and operations on npn−soft sets and some properties of the sets which are connected to operations have been established. Also, we have introduced the concept of npn−soft matrix and their operators which are more functional to make theoretical studies in the npn−soft set theory. Finally, we proposed the decision making method on the npn−soft set theory which can be applied to problems of many fields that contain uncertainty and provided an example that demonstrated that this method can be successfully worked. 2010 AMS Classification: 03E72, 08A72
Maximum Boost Control for 7-level Z-source Cascaded H-Bridge Inverter

Received Feb 14, 2017 Revised Apr 14, 2017 Accepted Apr 28, 2017 This paper proposes maximum boost control for 7-level z-source cascaded h-bridge inverter and their affiliation between voltage boost gain and modulation index. Z-source network avoids the usage of external dc-dc boost converter and improves output voltage with minimised harmonic content. Z-source network utilises distinctive LC impedance combination with 7-level cascaded inverter and it conquers the conventional voltage source inverter. The maximum boost controller furnishes voltage boost and maintain constant voltage stress across power switches, which provides better output voltage with variation of duty cycles. Single phase 7-level z-source cascaded inverter simulated using matlab/simulink. Keyword:
Sleep apnea is an independent correlate of erectile and sexual dysfunction.

INTRODUCTION
Obstructive sleep apnea (OSA) has been linked with erectile dysfunction (ED), but it is unknown whether this association is maintained in the presence of other risk factors for ED.


AIM
The aim of this study was to evaluate the relationship between ED/sexual dysfunction and polysomnographic measures of sleep apnea in patients with known risk factors for ED.


METHODS
Prospective cross-sectional analysis of 401 male patients undergoing in-lab polysomnography for suspected OSA. Erectile (EF) and sexual function were assessed by the 15-item International Index of Erectile Function (IIEF-15) questionnaire.


MAIN OUTCOME MEASURES
Severity of OSA via apnea-hypopnea index (AHI) and mean/lowest nocturnal oxygen saturation (SaO(2)). The IIEF-15 including the sexual domains: EF, intercourse satisfaction, orgasmic function, sexual desire, and overall satisfaction.


RESULTS
OSA (AHI > 5/h) was diagnosed in 92% of patients. ED (EF subdomain < or = 25) was present in 69% of patients with, and 34% of patients without OSA (P < 0.001). Multivariate stepwise regression analyses including known risk factors for ED, such as age, obesity, coronary heart disease, peripheral occlusive disease, hypertension, diabetes, prostate surgery, and beta-blocker treatment, and measures of sleep apnea identified mean nocturnal SaO(2) as independently associated with ED (P = 0.002; mean [95% CI] normalized slope 0.126 [0.047; 0.205]). Age (P < 0.001), peripheral occlusive disease (P = 0.001), prostate surgery (P = 0.018), and hypertension (P = 0.021) were confirmed as risk factors for ED, but did not abolish the sleep apnea-associated risk. Similar results were obtained for sexual dysfunction. Logistic regression analysis using the diagnosis of ED (EF subdomain < or = 25) as binary dependent variable confirmed that mean nocturnal SaO(2) (P = 0.012), as well as age (P < 0.001) were independently associated with ED.


CONCLUSIONS
ED and overall sexual dysfunction were highly prevalent in patients with suspected OSA. Irrespective of known risk factors, mean nocturnal SaO(2) was an additional, independent correlate of these dysfunctions, suggesting that OSA-related intermittent nocturnal hypoxemia specifically contributes to their development.
Legal Document Retrieval using Document Vector Embeddings and Deep Learning

Domain specific information retrieval process has been a prominent and ongoing research in the field of natural language processing. Many researchers have incorporated different techniques to overcome the technical and domain specificity and provide a mature model for various domains of interest. The main bottleneck in these studies is the heavy coupling of domain experts, that makes the entire process to be time consuming and cumbersome. In this study, we have developed three novel models which are compared against a golden standard generated via the on line repositories provided, specifically for the legal domain. The three different models incorporated vector space representations of the legal domain, where document vector generation was done in two different mechanisms and as an ensemble of the above two. This study contains the research being carried out in the process of representing legal case documents into different vector spaces, whilst incorporating semantic word measures and natural language processing techniques. The ensemble model built in this study, shows a significantly higher accuracy level, which indeed proves the need for incorporation of domain specific semantic similarity measures into the information retrieval process. This study also shows, the impact of varying distribution of the word similarity measures, against varying document vector dimensions, which can lead to improvements in the process of legal information retrieval. keywords: Document Embedding, Deep Learning, Information Retrieval
A Novel Scheme for DVL-Aided SINS In-Motion Alignment Using UKF Techniques

In-motion alignment of Strapdown Inertial Navigation Systems (SINS) without any geodetic-frame observations is one of the toughest challenges for Autonomous Underwater Vehicles (AUV). This paper presents a novel scheme for Doppler Velocity Log (DVL) aided SINS alignment using Unscented Kalman Filter (UKF) which allows large initial misalignments. With the proposed mechanism, a nonlinear SINS error model is presented and the measurement model is derived under the assumption that large misalignments may exist. Since a priori knowledge of the measurement noise covariance is of great importance to robustness of the UKF, the covariance-matching methods widely used in the Adaptive KF (AKF) are extended for use in Adaptive UKF (AUKF). Experimental results show that the proposed DVL-aided alignment model is effective with any initial heading errors. The performances of the adaptive filtering methods are evaluated with regards to their parameter estimation stability. Furthermore, it is clearly shown that the measurement noise covariance can be estimated reliably by the adaptive UKF methods and hence improve the performance of the alignment.
Clinical associations of deliberate self-injury and its impact on the outcome of community-based and long-term inpatient treatment for personality disorder.

BACKGROUND
Deliberate self-injury (DSI) is significantly associated with personality disorder (PD). There are gaps in our knowledge of DSI as an indicator of severity of psychopathology, as moderator of outcome and with regard to its response to different treatment programs and settings.


METHODS
We compare 2 samples of PD with (n = 59) and without (n = 64) DSI in terms of clinical presentation, response to psychosocial treatment and relative outcome when treated with specialist long-term residential and community-based programs. We test the assumption that DSI is an appropriate indicator for long-term inpatient care by contrasting the outcomes (symptom severity and DSI recidivism) of the 2 DSI sub-groups treated in the 2 different approaches.


RESULTS
PD with DSI had greater severity of presentation on a number of variables (early maternal separation, sexual abuse, axis-I comorbidities, suicidality and inpatient episodes) than PD without DSI. With regard to treatment response, we found a significant 3-way interaction between DSI, treatment model and outcome at 24-month follow-up. PD with DSI treated in a community-based program have significantly greater chances of improving on symptom severity and recidivism of self-injurious behaviour compared to PD with DSI treated in a long-term residential program.


CONCLUSIONS
Although limitations in the study design invite caution in interpreting the results, the poor outcome of the inpatient DSI group suggests that explicit protocols for the management of DSI in inpatient settings may be beneficial and that the clinical indications for long-term inpatient treatment for severe and non-severe PD may require updating.
