A complex activity based emotion recognition algorithm for affect aware systems

The usefulness of affect aware systems can be summarized as optimizing the system's services to improve the user experience. A means to achieve this objective is to make the system aware of the real-world situations and enable intelligent emotion analysis of its users. The ability of smart systems to automatically recognize human affective behavior through their movements and to respond are the key challenges in this area of study. This paper thus proposes an algorithm that can effectively categorize the underlining emotion of an activity as positive or negative and then classify it amongst the six basic emotions — sadness, fear, happiness, anger, disgust and surprise [1]. To portray the efficacy of this proposed model, typical scenes in the context of a smart home have been analyzed and the results have been presented. The results presented show that the proposed model would help developers to understand user experiences in the form of user's emotions in any scenario, which would help them to improve or modify the existing technologies to enhance computerhuman interaction.
OPTIMIZING UNSUPERVISED LEARNING OF OPINION TARGETS FROM UNSTRUCTURED REVIEWS USING WORDNET BASED SEMANTIC ORIENTATION

Opinion Target identification is an important task of opinion mining problem. Several approaches have been employed for this task which can be broadly divided into two major categories: supervised and unsupervised. The supervised approaches require training data which need manual work and are mostly domain dependent. Unsupervised technique is most popularly used due to its two main advantages: domain independent and no need of training data. This paper presents optimization of an unsupervised approach for opinion target identification from unstructured reviews. The unsupervised approaches basically extract frequently observed features in text hence the infrequently occurred features are ignored. This paper utilizes lexical resources to identify infrequent features. Empirical results shows direct impact on the performance of the frequency based features extraction
Exhumation along the Fairweather fault, southeastern Alaska, based on low-temperature thermochronometry: FAIRWEATHER FAULT EXHUMATION, SOUTHEASTERN ALASKA

[1] The southern Alaskan syntaxis marks the spectacular junction between the >1000-km-long Pacific–North America transform margin and the Chugach–St. Elias belt, where subduction and terrane accretion drive rapid convergent deformation and rock uplift. New low-temperature thermochronometry reveals that intense orogenic deformation is not restricted to one side of the syntaxis but extends nearly 300 km south along the dextral Fairweather fault. Apatite and zircon (U-Th)/He ages as young as 0.9 and 2.0 Ma suggest maximum exhumation rates of nearly 2 mm/a in close proximity ( 0.5 mm/a along the entire plate margin. We estimate that long-term rock uplift accommodates ∼3 mm/a of fault-normal convergence in this area. This suggests that the Fairweather fault is slightly transpressive and highly partitioned, analogous to the central San Andreas fault. This convergence only accounts for ∼1/5 of the obliquity between Pacific plate motion and the continental margin, however, implying the deficit is taken up by 1–2 cm/a thrust-sinistral motion along the offshore Transition fault. Additionally, thermochronometry shows a marked increase in bedrock cooling coincident with onset of heavy glaciation, similar to what has been observed in other parts of the Pacific Northwest. The tectonically active Fairweather corridor is distinguished, however, by the magnitude of the acceleration and the depth of exhumation since Pliocene climate change.
AN-6003 “ Shoot-through ” in Synchronous Buck Converters

The synchronous buck circuit is in widespread use to provide “point of use” high current, low voltage power for CPU’s, chipsets, peripherals etc. In the synchronous buck converter, the power stage has a “high-side” (Q1 below) MOSFET to charge the inductor, and a “Low-side” MOSFET which replaces a conventional buck regulator’s “catch diode” to provide a low-loss recirculation path for the inductor current.
DC-DC Buck-Converter for MPPT of PV System

Although solar energy is available throughout the day its insolation varies from morning to evening and with changing climatic conditions. As the efficiency of solar PV panel is low it becomes mandatory to extract maximum power from the PV panel at any given period of time. Several maximum power point tracking (MPPT) techniques are proposed for the purpose. Incremental conductance MPPT technique has higher steady-state accuracy and environmental adaptability. This paper investigates implementation issues of Incremental conductance MPPT algorithm. High frequency DC-DC Buck converter is used to interface PV panel with load. The Matlab Simulink model of the system is developed and results are validated with experimental results obtained using laboratory prototype of the system.

Sexual partners, sexually transmitted infections, and prostate cancer risk.

BACKGROUND
The etiology of prostate cancer (PCa) is poorly understood. Sexual activity and sexually transmitted infections (STIs) are among factors under scrutiny, with controversial findings to date.


METHODS
We examined the association between the number and gender of sexual partners, STIs and PCa risk in the context of PROtEuS, a population-based case-control study set amongst the mainly French-speaking population in Montreal, Canada. The study included 1590 histologically-confirmed PCa cases diagnosed in a Montreal French hospital between 2005 and 2009, and 1618 population controls ascertained from the French electoral list, Montreal residents, frequency-matched to cases by age. In-person interviews elicited information on sociodemographic, lifestyle and environmental factors. Unconditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) between sexually related factors and PCa risk, adjusting for age, ancestry, family history of PCa, and PCa screening history.


RESULTS
Subjects with more than 20 sexual partners in their lifetime had a decreased risk of PCa (OR 0.78, 95% CI 0.61-1.00) as did subjects who specifically had more than 20 female sexual partners (OR 0.72, 95% CI 0.56-0.94). By contrast, having had several male sexual partners appeared to confer some excess in risk of PCa. No association emerged for history of STIs and PCa but STIs prevalence was low.


CONCLUSION
Our findings are in support of a role for the number of sexual partners in PCa development. The gender of sexual partners should be taken into account in future studies investigating this association.
Filmed v. live social contact interventions to reduce stigma: randomised controlled trial.

BACKGROUND
Direct social contact interventions are known to reduce mental health stigma. Filmed social contact may be equally effective and have practical and cost advantages.


AIMS
To compare the effectiveness of a DVD, a live intervention and a lecture control, in reducing stigma, testing the hypotheses that: (a) DVD and live interventions will be equally effective; and (b) the interventions with social contact (DVD/live) will be more effective than the lecture. Cost-effectiveness, process and acceptability are also assessed.


METHOD
Student nurses were randomised to: (a) watch a DVD of service users/informal carers talking about their experiences, (b) watch a similar live presentation, or (c) attend a lecture. Primary outcomes were changes in attitudes (using the Mental Illness: Clinicians Attitudes Scale, MICA), emotional reactions (using the Emotional Reactions to Mental Illness Scale, ERMIS), intended proximity (using the Reported and Intended Behaviour Scale, RIBS), and knowledge (using the Social Contact Intended Learning Outcomes, SCILO), immediately after the intervention and at 4-month follow-up.


RESULTS
For the 216 participants, there were no differences between the DVD and live groups on MICA, ERMIS or RIBS scores. The DVD group had higher SCILO (knowledge) scores. The combined social contact group (DVD/live) had better MICA and RIBS scores than the lecture group, the latter difference maintained at 4 months. The DVD was the most cost-effective of the interventions, and the live session the most popular.


CONCLUSIONS
Our hypotheses were confirmed. This study supports the wider use of filmed social contact interventions to reduce stigma about mental illness.
The optimal choice of moments in dynamic panel data models

Empirical researchers frequently use dynamic panel data models and employ Generalized Method of Moments (GMM) estimators (Hansen, 1982) to estimate model parameters. An important practical problem in the estimation of a dynamic panel data model is the choice of moments as it provides a large number of moment conditions. Even though adding moment conditions leads to efficiency gain according to the conventional asymptotic theory, it has been observed that in finite samples the GMM estimator behaves poorly in the presence of a large number of moment conditions, mainly due to bias. This paper derives the Nagar (1959) approximation of the mean squared error of the GMM estimator in dynamic panel data models with lagged dependent variable and strictly exogenous covariates. It shows that additional instruments should be included on the basis of how well they approximate the unobserved fixed effects. Using this result, a procedure for choosing the number of instruments and a procedure for shrinking the effects of additional instruments are proposed. Both methods are based on minimization of the asymptotic mean squared error. Monte Carlo experiments are conducted to compare the performance of these procedures with that of the GMM estimator using all the available moment conditions and that of the GMM estimator using a minimal subset of moment conditions. The results from the Monte Carlo study suggest that applying these procedures improves the GMM estimator in terms of mean squared error and that the confidence intervals based on the new estimation procedures have good coverage rates. The proposed methods are then applied to estimate a model of income dynamics, using PSID data, and an employment equation, using Spanish firm data.
Ultra-wide bandwidth time-hopping spread-spectrum impulse radio for wireless multiple-access communications

Attractive features of time-hopping spread-spectrum multiple-access systems employing impulse signal technology are outlined, and emerging design issues are described. Performance of such communications systems in terms of achievable transmission rate and multiple-access capability are estimated for both analog and digital data modulation formats under ideal multiple-access channel conditions.
Processing and Normalizing Hashtags

We present ongoing work in linguistic processing of hashtags in Twitter text, with the goal of supplying normalized hashtag content to be used in more complex natural language processing (NLP) tasks. Hashtags represent collectively shared topic designators with considerable surface variation that can hamper semantic interpretation. Our normalization scripts allow for the lexical consolidation and segmentation of hashtags, potentially leading to improved semantic classification.
Cyclic Testing of Ductile End Diaphragms for Slab-on-Girder Steel Bridges

Ductile end diaphragms have been proposed as seismic retrofit strategy to protect the substructures of existing steel slab-on-girder bridges from damage during earthquakes. This paper presents the results from an experimental program to investigate the adequacy of some proposed details. Cyclic tests on full-size girder specimens having the proposed ductile diaphragms demonstrate that these can possess adequate initial elastic stiffness, strength, and capacity to dissipate hysteretic energy in the intended manner. The specimens developed a rotational capacity of 0.2 rad when energy dissipation devices of the TADAS (Triangular-plate Added Damping And Stiffness) type were used, and link distortion angles of 0.08 to 0.11 rad when eccentrically braced frame and shear panel systems were in place, corresponding to average ductilities of 8 to 10 before failure. Better performance of the eccentrically braced frame system would have been possible had lateral support been provided at the ductile link. However, ductile end diaphragms having bolted connections suffered significant slippage, leading to pinched hysteretic curves. Tests show that welding significantly improves the seismic behavior of these ductile systems. Specimens with nominal channel diaphragms and those without any diaphragm dissipated significantly less hysteretic energy, and suffered bolt rupture, buckling of the web stiffeners, and fracture of the stiffeners welds at large drifts.
Balance as bias : global warming and the US prestige press $

This paper demonstrates that US prestige-press coverage of global warming from 1988 to 2002 has contributed to a significant divergence of popular discourse from scientific discourse. This failed discursive translation results from an accumulation of tactical media responses and practices guided by widely accepted journalistic norms. Through content analysis of US prestige press— meaning the New York Times, the Washington Post, the Los Angeles Times, and the Wall Street Journal—this paper focuses on the norm of balanced reporting, and shows that the prestige press’s adherence to balance actually leads to biased coverage of both anthropogenic contributions to global warming and resultant action. r 2003 Elsevier Ltd.

Evolving Games and Essential Nets for Affine Polymorphism

This paper presents a game model of Second-order Intuitionistic Multiplicative Affine Logic (IMAL2). We extend Lamarche's essential nets to the second-order affine setting and use them to show that the model is fully and faithfully complete.
Concomitant Continuous Infusion Chemotherapy and Radiation

Attempts to duplicate the cytotoxic effect of oxygen on radioresistant tissues spurred a search by radiation oncologists for other radiosensitizing techniques. This led to large-scale investigations using neutrons and other heavy particle radiations, hyperthermia, altered fractionation schedules, and the systemic use of the halogenated pyrimidines and the electron-affinic compounds. Unfortunately, the promise that the nitroimidazole compounds would selectively sensitize the radioresistant tumor cells and prove to be an effective systemic agent has not been borne out in clinical trials thus far. Existing pharmokinetic and cytokinetic studies have suggested that continuous infusion chemotherapy given concomitantly (CCIC) with irradiation (RT) acts synergistically, resulting in a significant increase in tumor cell killing. These observations have been supported by clinical research studies treating certain epithelial cancers that have resulted in considerably higher locoregional control rates and improved survival. Although initially used in treatment of only advanced or inoperable epithelial carcinomas, CCIC and RT are now being employed in the treatment of lower staged cancers as an organ-sparing procedure. Carcinoma of the anus treated by anteroposterior (AP) resection alone have reported 5-year survival rates of 30% to 60%. CCIC and RT using 5-fluorouracil (5-FU) and mitomycin C have achieved a local control rate of 90% to 100% and a 5-year survival rate of 80% to 86% with sphincter preservation in 90% of these cases. The 5-year survival rate in advanced urinary bladder carcinoma is 25% to 30% for either radiation or surgery and 42% when combined in a preoperative radiation schedule. Using 5-FU CCIC and RT, the local control rate of transitional cell carcinoma of the bladder has been 71% to 86% with a 5-year survival of 62%. 5-FU CCIC and cisplatin and RT used in the treatment of Stages III and IV carcinoma of the cervix yields a locoregional control of 74% compared with the radiation alone local control of 63% for Stage III and 30% for Stage IV disease. Advanced head and neck and paranasal sinus carcinomas treated by cisplatin CCIC and RT show improved tumor clearance even in the presence of bone destruction. A complete response rate of 87% has been reported with the use of cisplatin CCIC and hyperfractionated radiation. Hyperfractionated radiation also appears to improve the local control of advanced head and neck cancers over patients treated with single fractions of radiation with 66% surviving at 22 months.(ABSTRACT TRUNCATED AT 400 WORDS)
IntuPaint: Bridging the gap between physical and digital painting

This paper presents a novel interface for a digital paint system: IntuPaint. A tangible interface for a digital paint easel, using an interactive surface and electronic brushes with a tuft of bristles, has been developed. The flexible brush bristles conduct light by means of total internal reflection inside the individual bristles. This enables to capture subtle paint nuances of the artist in a way that was not possible in previous technologies. This approach provides natural interaction and enables detailed tracking of specific brush strokes. Additional tangible and finger-based input techniques allow for specific paint operations or effects. IntuPaint also offers an extensive model-based paint simulation, rendering realistic paint results. The reality-based approach in the combination of user interface and paint software is a new step forward to bridge the gap between physical and digital painting, as is demonstrated by initial user tests.

European experience with the second-generation Edwards SAPIEN XT transcatheter heart valve in patients with severe aortic stenosis: 1-year outcomes from the SOURCE XT Registry.

OBJECTIVES
The SOURCE XT Registry (Edwards SAPIEN XT Aortic Bioprosthesis Multi-Region Outcome Registry) assessed the use and clinical outcomes with the SAPIEN XT (Edwards Lifesciences, Irvine, California) valve in the real-world setting.


BACKGROUND
Transcatheter aortic valve replacement is an established treatment for high-risk/inoperable patients with severe aortic stenosis. The SAPIEN XT is a balloon-expandable valve with enhanced features allowing delivery via a lower profile sheath.


METHODS
The SOURCE XT Registry is a prospective, multicenter, post-approval study. Data from 2,688 patients at 99 sites were analyzed. The main outcome measures were all-cause mortality, stroke, major vascular complications, bleeding, and pacemaker implantations at 30-days and 1 year post-procedure.


RESULTS
The mean age was 81.4 ± 6.6 years, 42.3% were male, and the mean logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) was 20.4 ± 12.4%. Patients had a high burden of coronary disease (44.2%), diabetes (29.4%), renal insufficiency (28.9%), atrial fibrillation (25.6%), and peripheral vascular disease (21.2%). Survival was 93.7% at 30 days and 80.6% at 1 year. At 30-day follow-up, the stroke rate was 3.6%, the rate of major vascular complications was 6.5%, the rate of life-threatening bleeding was 5.5%, the rate of new pacemakers was 9.5%, and the rate of moderate/severe paravalvular leak was 5.5%. Multivariable analysis identified nontransfemoral approach (hazard ratio [HR]: 1.84; p < 0.0001), renal insufficiency (HR: 1.53; p < 0.0001), liver disease (HR: 1.67; p = 0.0453), moderate/severe tricuspid regurgitation (HR: 1.47; p = 0.0019), porcelain aorta (HR: 1.47; p = 0.0352), and atrial fibrillation (HR: 1.41; p = 0.0014), with the highest HRs for 1-year mortality. Major vascular complications and major/life-threatening bleeding were the most frequently seen complications associated with a significant increase in 1-year mortality.


CONCLUSIONS
The SOURCE XT Registry demonstrated appropriate use of the SAPIEN XT THV in the first year post-commercialization in Europe. The safety profile is sustained, and clinical benefits have been established in the real-world setting. (SOURCE XT Registry; NCT01238497).
The role of the hydrophobic bonding in P-450 and the effect of organic compounds on the conversion of P-450 to P-420.

Abstract The conversion of cytochrome P-450 to P-420 by organic solvents was studied. The transition concentrations of ureas used for conversion of P-450 to P-420 were, in decreasing order: urea, N -methylurea, 1,1-dimethylurea, ethylurea, tetramethylurea, 1,3-diethylurea. Similar results were obtained with amides. The transition concentrations of anilines and phenols closely paralleled the π values of the organic compounds. To maintain the structure which gives P-450 its unusual properties in comparison with other known hemoproteins, the hydrophobic bonding in P-450 appears to play an important role in that it binds the heme plane to the apoprotein.
Effect of a structural intervention for the prevention of intimate-partner violence and HIV in rural South Africa: a cluster randomised trial

BACKGROUND
HIV infection and intimate-partner violence share a common risk environment in much of southern Africa. The aim of the Intervention with Microfinance for AIDS and Gender Equity (IMAGE) study was to assess a structural intervention that combined a microfinance programme with a gender and HIV training curriculum.


METHODS
Villages in the rural Limpopo province of South Africa were pair-matched and randomly allocated to receive the intervention at study onset (intervention group, n=4) or 3 years later (comparison group, n=4). Loans were provided to poor women who enrolled in the intervention group. A participatory learning and action curriculum was integrated into loan meetings, which took place every 2 weeks. Both arms of the trial were divided into three groups: direct programme participants or matched controls (cohort one), randomly selected 14-35-year-old household co-residents (cohort two), and randomly selected community members (cohort three). Primary outcomes were experience of intimate-partner violence--either physical or sexual--in the past 12 months by a spouse or other sexual intimate (cohort one), unprotected sexual intercourse at last occurrence with a non-spousal partner in the past 12 months (cohorts two and three), and HIV incidence (cohort three). Analyses were done on a per-protocol basis. This trial is registered with ClinicalTrials.gov, number NCT00242957.


FINDINGS
In cohort one, experience of intimate-partner violence was reduced by 55% (adjusted risk ratio [aRR] 0.45, 95% CI 0.23-0.91; adjusted risk difference -7.3%, -16.2 to 1.5). The intervention did not affect the rate of unprotected sexual intercourse with a non-spousal partner in cohort two (aRR 1.02, 0.85-1.23), and there was no effect on the rate of unprotected sexual intercourse at last occurrence with a non-spousal partner (0.89, 0.66-1.19) or HIV incidence (1.06, 0.66-1.69) in cohort three.


INTERPRETATION
A combined microfinance and training intervention can lead to reductions in levels of intimate-partner violence in programme participants. Social and economic development interventions have the potential to alter risk environments for HIV and intimate-partner violence in southern Africa.
