WE-LDA: A Word Embeddings Augmented LDA Model for Web Services Clustering

Due to the rapid growth in both the number and diversity of Web services on the web, it becomes increasingly difficult for us to find the desired and appropriate Web services nowadays. Clustering Web services according to their functionalities becomes an efficient way to facilitate the Web services discovery as well as the services management. Existing methods for Web services clustering mostly focus on utilizing directly key features from WSDL documents, e.g., input/output parameters and keywords from description text. Probabilistic topic model Latent Dirichlet Allocation (LDA) is also adopted, which extracts latent topic features of WSDL documents to represent Web services, to improve the accuracy of Web services clustering. However, the power of the basic LDA model for clustering is limited to some extent. Some auxiliary features can be exploited to enhance the ability of LDA. Since the word vectors obtained by Word2vec is with higher quality than those obtained by LDA model, we propose, in this paper, an augmented LDA model (named WE-LDA) which leverages the high-quality word vectors to improve the performance of Web services clustering. In WE-LDA, the word vectors obtained by Word2vec are clustered into word clusters by K-means++ algorithm and these word clusters are incorporated to semi-supervise the LDA training process, which can elicit better distributed representations of Web services. A comprehensive experiment is conducted to validate the performance of the proposed method based on a ground truth dataset crawled from ProgrammableWeb. Compared with the state-of-the-art, our approach has an average improvement of 5.3% of the clustering accuracy with various metrics.
Barriers to condom use: Results for men and women enrolled in HIV risk reduction trials in outpatient drug treatment

ABSTRACT HIV transmission often occurs through heterosexual high-risk sex. Even in the era of HIV combination prevention, promoting condom use and understanding barriers to consistent condom use remain priorities, especially among substance-dependent individuals. Men and women (N = 729) in outpatient drug treatment participated in a five-session gender-specific risk reduction group or one-session HIV Education group. Condom barriers (Motivation, Partner-related, Access/Availability, Sexual experience) were assessed at baseline and 6-month follow-up. Completing either intervention was associated with fewer motivation and partner-related barriers. Among women, reductions in motivation and sexual experience barriers were associated with less sexual risk with primary partners. Condom barriers are important to gender-specific HIV prevention; given limited resources, brief interventions maximizing active components are needed.
How culture affects ICT diffusion among SMEs in Bangladesh

Culture is a broad spectrum of behavioural study which has been illuminated differently in different literature. Applying four cultural dimensions, power distance, uncertainty avoidance, in-group collectivism, and Bengali value, with the two fundamental antecedents of TAM, perceived usefulness and ease of use, this study attempts to look at the effects of culture in ICT diffusion among SMEs in Bangladesh. This study applies a mixed method of research approach. Following an in-depth field study which is analysed through NVivo version 9, a descriptive research design is administered to ascertain the joint impact of the study constructs. Structural equation modelling through PLS graph has been used with a cross-sectional dataset of 51 SMEs in Bangladesh collected through a questionnaire survey. The proposed model was assessed with two step procedure of measuring latent variables structural association. Prior to estimating the structural model, psychometric properties of the model, convergent and discriminant validity, were assessed. The structural model estimation results reveal a significant association of power distance and perceived ease of use with SMEs intention to use ICT. The path analysis furthered a significant effect of intention on actual ICT usage behaviour. The study concludes with implications.
Dynamics of triacylglycerol and EPA production in Phaeodactylum tricornutum under nitrogen starvation at different light intensities

Lipid production in microalgae is highly dependent on the applied light intensity. However, for the EPA producing model-diatom Phaeodactylum tricornutum, clear consensus on the impact of incident light intensity on lipid productivity is still lacking. This study quantifies the impact of different incident light intensities on the biomass, TAG and EPA yield on light in nitrogen starved batch cultures of P. tricornutum. The maximum biomass concentration and maximum TAG and EPA contents were found to be independent of the applied light intensity. The lipid yield on light was reduced at elevated light intensities (>100 μmol m-2 s-1). The highest TAG yield on light (112 mg TAG molph-1) was found at the lowest light intensity tested (60 μmol m-2 s-1), which is still relatively low to values reported in literature for other algae. Furthermore, mass balance analysis showed that the EPA fraction in TAG may originate from photosynthetic membrane lipids.
OF HARVEST INDEX AND BIOLOGICAL YIELD IN BREAD WHEAT ( Triticum aestivum L . )

Golpavar Reza A. (2014): Genetic control and heredity of harvest index and biological yield in bread wheat (Triticum aestivum L.). Genetika, Vol 46, No. 1, 43-48. Assessment of genetic control, mode of inheritance, general and specific combining abilities and effect of drought stress on genetic parameters of harvest index and biological yield traits in bread wheat were achieved by using Diallel mating design. Parents (eight cultivars) along with F1 progenies (28 crosses) were sown in a randomized complete blocks design with three replications under stress condition in Karadj Agricultural Research Center. The data were analyzed according to methed of Hallauer and Miranda as well as fixed model of Griffing’s method II. Jinks-Hayman model was used to estimate broad and narrow-sense heritabilities and mean degree of dominance. There were significant differences between genotypes for mentioned traits in both environments. Studying mean of squares of general combining ability (GCA), specific combining ability (SCA), the ratio of GCA to SCA mean of squares and portion of additive and dominance variances showed importance of both additive and non additive gene effects for harvest index, but in biological yield heredity, additive effect was more important. Estimating broad-sense and narrow-sense heritabilities showed low efficiency of harvest index and high efficiency of biological yield for selection programs in stress environments.
Gene Associated with Halitosis mgl Tea Catechin EGCg Suppresses the

Epigallocatechin gallate (EGCg), the main antimicrobial tea catechin, has been reported to inhibit growth and virulence factors of oral pathogens in vitro. Although the mechanism is unclear, the potential of EGCg in reducing halitosis caused by volatile sulfur compounds (VSCs) has been suggested. This study tested the hypothesis that EGCg reduces VSCs by suppressing mgl, the gene encoding L-methionine-α-deamino-γ-mercaptomethanelyase, responsible for methyl mercaptan (CH3SH) production by oral anaerobes. In this study, the effect of EGCg on in vitro growth, CH3SH production, and mgl gene expression in P. gingivalis W83 was investigated. EGCg inhibited growth of P. gingivalis W83 (MIC = 97.5 μg/mL) and was bactericidal (MBC = 187.5 μg/mL). At sub-MIC levels, EGCg inhibited CH3SH production, and mgl mRNA and protein expression (p < 0.05). We conclude that EGCg may represent a natural and alternative agent to the antimicrobial chemicals currently available for halitosis control.
Resting Energy Expenditure and Energy Substrate Utilization in Children with Duchenne Muscular Dystrophy

The high prevalence of obesity at an early stage of Duchenne muscular dystrophy (DMD) could result not solely from reduced physical activity, but may also involve low resting energy expenditure (REE), abnormal nutrient utilization, or overfeeding. We hypothesized that the dramatic muscle mass loss in DMD should reduce the REE. REE was measured by indirect calorimetry in 13 9-13-y-old DMD boys (5 obese, 8 nonobese) and 9 male age-matched controls. Muscle mass was estimated from 3-d creatinine excretion in urine. Daily energy intake was estimated from 7-d diet records. In the nonobese DMD group (NODMD) the muscle mass was reduced by 71%, and the REE was 13% lower than in controls(47.5 versus 54.6 kcal·h-1, p < 0.05). Postabsorptive respiratory quotients appeared higher in both DMD groups than in the controls; however, the difference was significant only for the NODMD group (0.88 versus 0.83, p < 0.05). Respiratory quotients were not different between the two DMD groups. Diet records were not contributive in revealing a different dietary behavior between groups. Our results suggest that: 1) muscle mass loss in DMD is associated with a low REE, 2) low postabsorptive fat utilization might occur at an early stage of the disease, and 3) obesity is not associated with an increase in fat utilization in DMD. This study warrants further research to test low REE and low fat utilization as risk factors in developing obesity in DMD.
Implementation of Mother-Training Program to Improve Parenting in Pre-School Age Children: A Randomized-Controlled Trial

Background: Preventing child abuse is an area of evaluation that should be deeply considered. The enhancing skill of maternal child care is also useful in this field. Aim: The aim of this study was to assess the impact of a training strategy to improve parenting in the families identified as at risk of child maltreatment. Materials and Methods: This randomized and controlled trial was conducted in 60 mothers allocated in the experimental and controlled group by a simple random allocation in Amirkola Children's Hospital in North Iran from January 2009 to December 2009. Mean score of maternal child abuse before and after intervention has been assessed by Conflict Tactics Scale for Parent and Child. Data analysis was based on the independent t-test, the paired t-test and one way analysis of variance. Results: The mean and standard deviation of maternal child abuse score in the experimental group before and after intervention were 30.21 ± 1.21 and 23.31 ± 1.52, respectively, (P < 0.001, t = 6.63), but no difference was found in the control group. Conclusions: The training program on maternal skills to prevent child abuse was a powerful resource. Therefore, healthcare providers in the field of pediatric about parenting skills should be taught with a specific consideration.
From Julius Caesar to Sustainable Composite Materials: A Passage through Port Caisson Technology

The breakwater construction technique using floating concrete caissons is well-known nowadays as a widespread system. Yet do we really know its origin? Since Julius Caesar used this technology in Brindisi (Italy) up to the Normandy landings in June 1944, not only has this technology been developed, but it has been a key item in several moments in history. Its development has almost always been driven by military requirements. The greatest changes have not been conceptual but point occurring, backed by the materials used. Parallelisms can be clearly seen in each new stage: timber, opus caementitium (Roman concrete), iron and concrete… However, nowadays, achieving a more sustainable world constitutes a major challenge, to which the construction of caissons breakwaters must contribute as a field of application of new eco-friendly materials. This research work provides a general overview from the origins of caissons until our time. It will make better known the changes that took place in the system and their adaptation to new materials, and will help in clarifying the future in developing technology towards composite sustainable materials and special concrete. If we understand the past, it will be easier to define the future.
3 D Radial Projection Technique With Ultrashort Echo Times for Sodium MRI : Clinical Applications in Human Brain and Skeletal Muscle

Na MRI has the potential to noninvasively detect sodium (Na) content changes in vivo. The goal of this study was to implement Na MRI in a clinical setting for neurooncological and muscular imaging. Due to the biexponential T2 decay of the tissue Na signal with a short component, which ranges between 0.5–8 ms, the measurement of total Na content requires imaging techniques with echo times (TEs) below 0.5 ms. A 3D radial pulse sequence with a TE of 0.2 ms at a spatial resolution of 4 4 4 mm was developed that allows the acquisition and presentation of Na images on the scanner. This sequence was evaluated in patients with lowand high-grade gliomas, and higher Na MR signals corresponding to an increased Na content were found in the tumor regions. The contrast-to-noise ratio (CNR) between tumor and white matter increased from 0.8 0.2 to 1.3 0.3 with tumor grade. In patients with an identified muscular Na channelopathy (Paramyotonia congenita (PC)), induced muscle weakness led to a signal increase of 18% in the Na MR images, which was attributed to intracellular Na accumulation in this region.

Title Multiproduct firms , export product scope and tradeliberalization : the role of managerial efficiency

This paper provides a theoretical and empirical analysis on the effects of one-sided trade liberalization on firms’ export product scope. The model explicitly incorporates the cost of managing production and sales in addition to the usually-modeled production cost. The analysis predicts that the home country’s tariff cut reduces all home firms’ export product scope; whereas in response to the foreign country’s tariff cut, a home firm’s export product scope expands (shrinks) if the firm’s management cost is low (high), independent of the firm’s production cost. These predictions are confirmed by our empirical analysis based data of Chinese firms from 2000 to 2006. JEL: F12, F13, F15
Learning, Not Adaptation, Characterizes Stroke Motor Recovery: Evidence From Kinematic Changes Induced by Robot-Assisted Therapy in Trained and Untrained Task in the Same Workspace

Both the American Heart Association and the VA/DoD endorse upper-extremity robot-mediated rehabilitation therapy for stroke care. However, we do not know yet how to optimize therapy for a particular patient's needs. Here, we explore whether we must train patients for each functional task that they must perform during their activities of daily living or alternatively capacitate patients to perform a class of tasks and have therapists assist them later in translating the observed gains into activities of daily living. The former implies that motor adaptation is a better model for motor recovery. The latter implies that motor learning (which allows for generalization) is a better model for motor recovery. We quantified trained and untrained movements performed by 158 recovering stroke patients via 13 metrics, including movement smoothness and submovements. Improvements were observed both in trained and untrained movements suggesting that generalization occurred. Our findings suggest that, as motor recovery progresses, an internal representation of the task is rebuilt by the brain in a process that better resembles motor learning than motor adaptation. Our findings highlight possible improvements for therapeutic algorithms design, suggesting sparse-activity-set training should suffice over exhaustive sets of task specific training.
Environmental Quality and its Human Health Effects : A Causal Analysis for the EU-25

Life expectancy at birth is one of the important key indicators of population health and economic development of a country. Life expectancy has increased rapidly due to onset of industrialization and modernization in the world. On the other hand, along with a high population growth in the world the fact that the deterioration of the environmental quality is related to serious human health issues is reason that the relationship between environmental quality and health is investigated both by many researchers and by policy makers. The main objective of this study was to determine whether there exists a causal relationship between environment and health for EU countries. The analysis shows that there exists causal relationships among health, education and environmental quality, is proxied by carbon dioxide emissions in terms of consumption coal, natural gas and petroleum. This also shows that environmental quality could be considered as a constraint for economic growth, is related to the causes of education and the quality of human life in EU-25 member countries.
Crystal structure of F65A/Y131C-methylimidazole carbonic anhydrase V reveals architectural features of an engineered proton shuttle.

The crystal structure of F65A/Y131C murine alpha-carbonic anhydrase V (CAV), covalently modified at cysteine residues with 4-chloromethylimidazole, is reported at 1.88 A resolution. This modification introduces a methylimidazole (MI) group at residue C131 in the active site with important consequences. F65A/Y131C-MI CAV exhibits an up to 3-fold enhancement of catalytic activity over that of wild-type CAV [Earnhardt, J. N. , Wright, S. K. , Qian, M. , Tu, C. , Laipis, P. J., Viola, R. E. , and Silverman, D. N. (1999) Arch. Biochem. Biophys. 361, 264-270]. In this modified CAV variant, C131-MI acts as a proton shuttle, facilitating the deprotonation of a zinc-bound water molecule to regenerate the nucleophilic zinc-bound hydroxide ion. A network of three hydrogen-bonded water molecules, across which proton transfer likely proceeds, bridges the zinc-bound water molecule and the C131-MI imidazole group. The structure of F65A/Y131C-MI CAV is compared to structures of Y64H/F65A murine CAV, wild-type human alpha-carbonic anhydrase II, and the gamma-carbonic anhydrase from Methanosarcina thermophilain an effort to outline common features of catalytic proton shuttles.
Risk factors for West Nile virus infection and disease in populations and individuals

West Nile virus (WNV) is a mosquito-borne enveloped positive-strand RNA virus that emerged in North America in 1999 in New York City. Over the past 15 years, WNV has become established throughout the USA and has spread into Canada, Mexico and the Caribbean. CDC reports indicate >41,000 clinical cases, including more than 1700 fatalities. An estimated 3 million people in the USA may have been infected to date. Infection with WNV is dependent on many factors including climate, mosquito habitats and immunologically naïve bird populations. In addition, variations within individuals contribute to the risk of severe disease, in particular, advanced age, hypertension, immunosuppression and critical elements of the immune response. Recent advances in technology now allow detailed analysis of complex immune interactions relevant to disease susceptibility.
End-to-Side Neurorrhaphy Resulting in Limited Sensory Axonal Regeneration in a Rat Model

This study evaluated reinnervation of an end-to-side neurorrhaphy and the resultant functional recovery in a rat model. The cut distal posterior tibial nerve was repaired to the side of an intact peroneal nerve. In one group, the epineurium of the peroneal nerve was left intact; in another group, the epineurium was stripped; in the third experimental group, a perineurial slit was created. Evaluations included walking track analysis, nerve conduction studies, muscle mass measurements, retrograde nerve tracing, and histologic evaluation. Walking tracks indicated poor functional recovery. No significant difference in nerve conduction between the experimental and control groups was seen. Gastrocnemius muscle mass measurements revealed no functional recovery in the end-to-side groups. Retrograde nerve tracing revealed minimal staining of motor neurons. However, sensory neuronal staining of the dorsal root ganglia occurred in all groups. Histology revealed minimal myelinated axonal regeneration. These results suggest that predominantly sensory neural regeneration occurs in an end-to-side neurorrhaphy at an end point of 16 weeks.
Does the p75 neurotrophin receptor mediate Aβ‐induced toxicity in Alzheimer's disease?

Alzheimer's disease is characterized by the over‐production and accumulation of amyloidogenic Aβ peptide, which can induce cell death in vitro. It has been suggested that the death signal could be transduced by the pan neurotrophin receptor (p75NTR). p75NTR is well known for its ability to mediate neuronal death in neurodegenerative conditions and is inextricably linked with changes that occur in Alzheimer's disease. Moreover, Aβ binds to p75NTR, activating signalling cascades. However, the complexity of p75NTR‐mediated signalling, which does not always promote cell death, leaves open the possibly of Aβ promoting death via an alternative signalling pathway or the regulation of other p75NTR‐mediated actions. This review focuses on the interactions between Aβ and p75NTR in the context of the broader p75NTR signalling field, and offers alternative explanations for how p75NTR might contribute to the aetiology of Alzheimer's disease.
Extracorporeal membrane oxygenation as a bridge to lung transplantation: a long-term study.

OBJECTIVES We investigated early outcomes in patients with end-stage pulmonary disease bridged with extracorporeal membrane oxygenation (ECMO) with the intention to perform lung transplantation (LTx). METHODS ECMO was used as a bridge to LTx in 20 patients between 2005 and 2013. Most patients suffered from rapid progress of disease and most failed to stabilize on mechanical ventilation. Sixteen patients (10 males, median age 42 years, range 25-59) underwent LTx after ECMO support for a median of 9 (range 1-229) days. Most patients were not on the waiting list while receiving ECMO, but after being assessed were on the waiting list for a median of 6 (range 1-72) days before LTx or death occurred. Median follow-up at 535 (range 36-3074) days was 100% complete, 9 patients have been followed for >1 year and 4 patients have been bridged during 2013. RESULTS Four patients died on ECMO waiting for a donor and as intention-to-treat, the success for bridging was 80% (16/20) and 1-year survival was 62% (10/16, not including 4 with <1-year follow-up). For those who underwent LTx, 3 patients died in-hospital after LTx on Days 0, 16 and 82, respectively, and currently, 11/16 (69%) are alive and 1-year survival for transplanted patients was 9/12 (75%). Median ICU stay before and after LTx was 9 (range 2-229) days and 20 (range 0-53) days, respectively. At follow-up, lung function was evaluated, and mean forced expiratory volume at 1 s and forced vital capacity were 56±22% of predicted and 74±24% of predicted, respectively. CONCLUSIONS ECMO used as a bridge to LTx results in acceptable survival in selected patients with end-stage pulmonary disease.
