This paper presents a review of existing research on this topic to ensure a comprehensive understanding of social commerce. First, we explore the evolution of social commerce from its marketing origins. Next, we examine various definitions of social commerce and the motivations behind it. We also investigate its advantages and disadvantages for both businesses and customers. Then, we explore two major tools for important for social commerce: Sentiment Analysis, and Social Network Analysis. By delving into well-known research papers in Information Retrieval and Complex Networks, we seek to present a survey of current research in multifarious aspects of social commerce to the scientific research community.
A high performance MEMS miniature tunable bandpass filter

A miniature tunable 3-pole filter is fabricated using coplanar waveguide (CPW) transmission-tines on glass substrate (C/sub r/ = 4.6, tan /spl delta/ = 0.006) and an array of RF-MEMS varactors. The filter is tuned using a bias voltage of 0-80 Volts. The filter is /spl sim/3.6 mm long and gives a near ideal frequency response. A tuning range of 14% from 18.6 to 21.4 GHz was achieved, with a constant fractional bandwidth of 7.4 /spl plusmn/ 0.1% and a mid-band insertion loss of 3.85-4.15 dB.
Effect of Cutting Parameters on Surface Roughness and Cutting Force in Turning Mild Steel

The purpose of this paper is to study the effect of speed, feed and depth of cut on surface roughness (Ra) and cutting force (Fc) in turning mild steel using high speed steel cutting tool. Experiments were conducted on a precision centre lathe and the influence of cutting parameters was studied using analysis of variance (ANOVA)based on adjusted approach. Based on the main effects plots obtained through full factorial design, optimum level for surface roughness and cutting force were chosen from the three levels of cutting parameters considered. Linear regression equation of cutting force has revealed that feed, depth of cut, and the interaction of feed and depth of cut significantly influenced the variance. In case of surface roughness, the influencing factors were found to be feed and the interaction of speed and feed. As turning of mild steel using HSS is one among the major machining operations in manufacturing industry, the revelation made in this research would significantly contribute to the cutting parameters’ optimization.
The effect of left ventricular (LV) remodeling on ventricular arrhythmia in cardiac resynchronization therapy (CRT-D) patients (antiarrhythmic effect of CRT).

BACKGROUND
In patients with low ejection fraction and ventricular dyssynchrony, cardiac resynchronization therapy (CRT) is an accepted therapeutic modality. In these patients, CRT can improve the quality of life and exercise tolerance in addition to improved survival. On the other hand, antiarrhythmic effects of CRT is a place of debate.


METHOD
In this study, we evaluated the effect of CRT-induced reverse remodeling on ventricular arrhythmia in heart failure patients. Patients with CRT were divided to two groups of responders and nonresponders. Responders were those with reduction of LVESD of more than 10% or increase in LVEF of more than 5%. They were visited and device analysis was performed during the follow-up.


RESULTS
One hundred and nineteen patients were enrolled in this study. Those with reverse remodeling experienced fewer ventricular arrhythmias after two years of follow-up (N = 2 vs 11, P = 0.001).


CONCLUSION
Reverse remodeling associated with CRT implantation can result in decreased frequency of ventricular arrhythmias.
Acne inversa.

Acne inversa (synonyms are intertriginous acne, acne triad, acne tetrad, hidradenitis suppurativa, pyodermia fistulans sinifica) is a chronic inflammatory disorder of the sebaceous follicles and terminal hair follicles and is one member of the acne family. It is characterized by acne conglobata in an inverse pattern involving the axillary, inguinal, and perigenital regions, together with perifolliculitis and abscesses on the nape and scalp. The severity of the condition varies from a few suppurating lesions to widespread and disabling disease.
Mediterranean versus vegetarian diet for cardiovascular disease prevention (the CARDIVEG study): study protocol for a randomized controlled trial

BACKGROUND
Nutrition is able to alter the cardiovascular health of the general population. However, the optimal dietary strategy for cardiovascular disease prevention is still far from being defined. Mediterranean and vegetarian diets are those reporting the greatest grade of evidence in the literature, but no experimental studies comparing these two dietary patterns are available.


METHODS/DESIGN
This is an open randomized crossover clinical trial including healthy subjects with a low-to-medium cardiovascular risk profile, characterized by being overweight and by the presence of at least an additional metabolic risk factor (abdominal obesity, high total cholesterol, high LDL cholesterol, high triglycerides, impaired glucose fasting levels) but free from medications. A total of 100 subjects will be included and randomly assigned to two groups: Mediterranean calorie-restricted diet (n = 50) and vegetarian calorie-restricted diet (n = 50). The intervention phases will last 3 months each, and at the end of intervention phase I the groups will be crossed over. The two diets will be isocaloric and of three different sizes (1400 - 1600 - 1800 kcal/day), according to specific energy requirements. Adherence to the dietary intervention will be established through questionnaires and 24-h dietary recall. Anthropometric measurements, body composition, blood samples and stool samples will be obtained from each participant at the beginning and at the end of each intervention phase. The primary outcome measure will be change in weight from baseline. The secondary outcome measures will be variations of anthropometric and bioelectrical impedance variables as well as traditional and innovative cardiovascular biomarkers.


DISCUSSION
Despite all the data supporting the efficacy of Mediterranean and vegetarian diets on the prevention of cardiovascular diseases, no studies have directly compared these two dietary profiles. The trial will test whether there are statistically significant differences between these dietary profiles in reducing the cardiovascular risk burden for the general population.

Simulation of small humanoid robots for soccer domain

In this paper, we illustrate the development of a realistic simulation of a humanoid robot model in a virtual environment using USARSim (Urban Search and Rescue Simulator). USARSim provides an accurate 3D simulation of a virtual environment with a detailed rendering and a realistic physics. Moreover, USARSim allows users to observe the virtual environment from different views. One of these is the egocentric view, which can simulate the camera mounted on the robot. The small humanoid robot presented in this work is Robovie-M, developed by VStone Ltd. (Japan). This robot is used by our team Artisti in the RobotCup soccer competitions. Reported experiments compare the behaviors of a real robot and of its virtual model, when controlled by the same control software to asses the possibility to faithfully simulate a robot with 22 degrees of freedom in USARSim. Moreover, we discuss the possibility to close the control loop of the robot in simulation, by simulating also the main robot sensor, i.e. the camera. The experiments show that USARSim, despite being a simple simulator based on a low cost computer game, provides an accurate enough simulation of the physics and a realistic rendering of the 3D scene enabling a faithfully simulation of a small humanoid robot at low cost. Thus, one can entirely test the robot software modules in the simulation (namely: the motion control modules, the vision system modules and, by closing the robot control loop in simulation, the behavior and behaviorselection modules).
Modeling Steel Frame Buildings in Three Dimensions-Part II : Elastofiber Beam Element and Examples

This is the second of two papers describing a procedure for the three dimensional nonlinear timehistory analysis of steel framed buildings. An overview of the procedure and the theory for the panel zone element and the plastic hinge beam element are presented in Part I. In this paper, the theory for an efficient new element for modeling beams and columns in steel frames called the elastofiber element is presented, along with four illustrative examples. The elastofiber beam element is divided into three segments two end nonlinear segments and an interior elastic segment. The cross-sections of the end segments are subdivided into fibers. Associated with each fiber is a nonlinear hysteretic stress-strain law for axial stress and strain. This accounts for coupling of nonlinear material behavior between bending about the major and minor axes of the cross-section and axial deformation. Examples presented include large deflection of an elastic cantilever, cyclic loading of a cantilever beam, pushover analysis of a 20-story steel moment-frame building to collapse, and strong ground motion analysis of a 2-story unsymmetric steel moment-frame building. 1Post-Doctoral Scholar, Seismological Laboratory, MC 252-21, California Institute of Technology, Pasadena, CA91125.

Learning the skill of archery by a humanoid robot iCub

We present an integrated approach allowing the humanoid robot iCub to learn the skill of archery. After being instructed how to hold the bow and release the arrow, the robot learns by itself to shoot the arrow in such a way that it hits the center of the target. Two learning algorithms are proposed and compared to learn the bi-manual skill: one with Expectation-Maximization based Reinforcement Learning, and one with chained vector regression called the ARCHER algorithm. Both algorithms are used to modulate and coordinate the motion of the two hands, while an inverse kinematics controller is used for the motion of the arms. The image processing part recognizes where the arrow hits the target and is based on Gaussian Mixture Models for color-based detection of the target and the arrow's tip. The approach is evaluated on a 53-DOF humanoid robot iCub.
GPS-GSM Integration for Enhancing Public Transportation Management Services

This paper proposes and implements a solution for enhancing public transportation management services based on GPS and GSM in Punjab province of Pakistan. The system consists of four modules: BUS Station Module, In-BUS Module, BASE Station Module and BUS Stop Module. Equipped with PC and GSM modem, BUS Station Module sends the initialization information containing the bus number and license plate number to In-BUS Module and BASE Station Module using SMS. The microcontroller based In-BUS Module consisting mainly of a GPS receiver and GSM modem then starts transmitting its location and number of passengers to BASE Station Module. BASE Station Module equipped with a microcontroller unit and GSM modems interfaced to PCs is designed to keep track record of every bus, processes user request about a particular bus location out of BUS Station and updates buses location on bus stops. BUS Stop Module is installed at every bus stop and consists of a GSM modem, memory unit and dot matrix display all interfaced to a microcontroller. This module receives buses location information coming towards that stop from BASE Station module and displays the information on a dot matrix display. A per stop statistical analysis is carried out based on the number of passengers and a recommendation report along with this analysis is sent to Punjab Government Transportation Department to have a check on the performance and services offered by transporters to common people. The results have shown that the developed system is useful for facilitating people using public transportation services.
Osler's nodes, Janeway lesions and splinter haemorrhages.

To cite: Hirai T, Koster M. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-009759 DESCRIPTION A 22-year-old man with a history of intravenous heroin misuse, presented with 1 week of fatigue and fever. Blood cultures were positive for methicillin-sensitive Staphylococcus aureus. Physical examination showed multiple painful 1– 2 mm macular rashes on the palm and soles bilaterally (figures 1 and 2). Splinter haemorrhages (figure 3) and conjunctival petechiae (figure 4) were also noted. A transoesophageal echocardiogram demonstrated a 16-mm vegetation on the mitral valve (figure 5). Vegitations >10 mm in diameter and infection involving the mitral valve are independently associated with an increased risk of embolisation. However, he decided medical management after extensive discussion and was treated with intravenous nafcillin for 6 weeks. He returned 8 weeks later with acute shortness of breath and evidence of a perforated mitral valve for which he subsequently underwent a successful mitral valve repair with an uneventful recovery.
Separable reversible encrypted data hiding in encrypted image using AES Algorithm and Lossy technique

The field steganography is very much popular technique for sending secrete message and lots of research are going in it. To overcome the limitation of previous work we proposed separable and reversible encrypted data hiding in encrypted image using AES Algorithm and Lossy technique as solution. In this sender encrypt data and image separately using AES algorithm, hides encrypted data in encrypted image using LSB technique, system auto generate the all 3 respective keys. Sender sends the file through existing mail system. Receiver can perform operation as per respective keys like if he has only data hiding and image decryption key then he can only get the image in original form or if he have data hiding and data decryption key then he can get original data, system also provides protection for auto generated keys and system auto generate mail if user fail to perform any operation.
Combination of long-acting HIV fusion inhibitor albuvirtide and LPV/r showed potent efficacy in HIV-1 patients

BACKGROUND
Long acting antiretroviral drugs represent a promising approach for chronic treatment of HIV infection. Here, we study the efficacy and safety of albuvirtide (ABT), an HIV-1 fusion inhibitor with a half life of 11-12 days in human.


METHODS
ABT was evaluated in a 7-week, open-label and randomized trial, combining with LPV/r. Twenty HIV-1-infected adults were assigned to two dose groups, receiving ABT (160 or 320 mg) given weekly and LPV/r given twice daily.


RESULTS
At week 7, the decline of HIV-1 RNA from baseline was 1.9 (1.3-2.3) log10 and 2.2 (1.6-2.7) log10 copies/ml, and suppression of HIV-1 RNA to below 50 copies/ml was achieved in 11.1 % (1/9) and 55.6 % (5/9) patients, for the 160 and 320 mg dose group respectively.


CONCLUSION
A clear dose-efficacy correlation of ABT was demonstrated. ABT combining with LPV/r is a promising two-drug regimen to be tested in larger patient population.
Active endocannabinoids are secreted on extracellular membrane vesicles.

Endocannabinoids primarily influence neuronal synaptic communication within the nervous system. To exert their function, endocannabinoids need to travel across the intercellular space. However, how hydrophobic endocannabinoids cross cell membranes and move extracellularly remains an unresolved problem. Here, we show that endocannabinoids are secreted through extracellular membrane vesicles produced by microglial cells. We demonstrate that microglial extracellular vesicles carry on their surface N-arachidonoylethanolamine (AEA), which is able to stimulate type-1 cannabinoid receptors (CB1), and inhibit presynaptic transmission, in target GABAergic neurons. This is the first demonstration of a functional role of extracellular vesicular transport of endocannabinoids.
Graph Analysis for Detecting Fraud, Waste, and Abuse in Healthcare Data

trillion a year. Driven by the market size, health care has become an important and fast growing application domain for data analytics. McKinsey’s influential report on big data analytics (Manyika et al. 2011) lists health care as the top most promising application domain. One significant problem of health care is the loss of health-care expenditures to fraud, waste, and abuse (FWA). Figure 1 lists the amount of improper payment in U.S. government expenditure. In 2012, improper payments totaled about $120 billion. Health-carerelated programs such as Medicaid, Medicare fee for service (FFS) and parts C and D contribute significantly, representing more than half of the total. A separate report from the Institute of Medicine (IOM) estimates the annual loss to FWA in the health-care domain to be $750 billion (Institute of Medicine 2012). The magnitude of the fraud problem has attracted many efforts from the health-care industry, the data-analytics industry, and research communities to develop fraud-detection systems. Articles
Parent-mediated early intervention for young children with autism spectrum disorder.

BACKGROUND
Recent estimates concerning the prevalence of autistic spectrum disorder are much higher than those reported 30 years ago, with at least 1 in 400 children affected. This group of children and families have important service needs. The involvement of parents in implementing intervention strategies designed to help their autistic children has long been accepted as helpful. The potential benefits are increased skills and reduced stress for parents as well as children.


OBJECTIVES
The objective of this review was to determine the extent to which parent-mediated early intervention has been shown to be effective in the treatment of children aged 1 year to 6 years 11 months with autistic spectrum disorder. In particular, it aimed to assess the effectiveness of such interventions in terms of the benefits for both children and their parents.


SEARCH STRATEGY
A range of psychological, educational and biomedical databases were searched. Bibliographies and reference lists of key articles were searched, field experts were contacted and key journals were hand searched.


SELECTION CRITERIA
Only randomised or quasi-randomised studies were included. Study interventions had a significant focus on parent-implemented early intervention, compared to a group of children who received no treatment, a waiting list group or a different form of intervention. There was at least one objective, child related outcome measure.


DATA COLLECTION AND ANALYSIS
Appraisal of the methodological quality of included studies was carried out independently by two reviewers. Differences between the included studies in terms of the type of intervention, the comparison groups used and the outcome measures were too great to allow for direct comparison.


MAIN RESULTS
The results of this review are based on data from two studies. Two significant results were found to favour parent training in one study: child language and maternal knowledge of autism. In the other, intensive intervention (involving parents, but primarily delivered by professionals) was associated with better child outcomes on direct measurement than were found for parent-mediated early intervention, but no differences were found in relation to measures of parent and teacher perceptions of skills and behaviours.


REVIEWER'S CONCLUSIONS
This review has little to offer in the way of implications for practice: there were only two studies, the numbers of participants included were small, and the two studies could not be compared directly to one another. In terms of research, randomised controlled trials involving large samples need to be carried out, involving both short and long-term outcome information and full economic evaluations. Research in this area is hampered by barriers to randomisation, such as availability of equivalent services.
Candida transmission and sexual behaviors as risks for a repeat episode of Candida vulvovaginitis.

OBJECTIVE
To assess associations between female and male factors and the risk of recurring Candida vulvovaginitis.


METHODS
A prospective cohort study of 148 women with Candida vulvovaginitis and 78 of their male sexual partners was conducted at two primary care practices in the Ann Arbor, Michigan, area.


RESULTS
Thirty-three of 148 women developed at least one further episode of Candida albicans vulvovaginitis within 1 year of follow-up. Cultures of Candida species from various sites of the woman (tongue, feces, vulva, and vagina) and from her partner (tongue, feces, urine, and semen) did not predict recurrences. Female factors associated with recurrence included recent masturbating with saliva (hazard ratio 2.66 [95% CI 1.17-6.06]) or cunnilingus (hazard ratio 2.94 [95% CI 1.12-7.68]) and ingestion of two or more servings of bread per day (p </= 0.05). Male factors associated with recurrences in the woman included history of the male masturbating with saliva in the previous month (hazard ratio 3.68 [95% CI 1.24-10.87]) and lower age at first intercourse (hazard ratio 0.83 [95% CI 0.71-0.96]).


CONCLUSIONS
Sexual behaviors, rather than the presence of Candida species at various body locations of the male partner, are associated with recurrences of C. albicans vulvovaginitis.
A 10-year population-based study of people with multiple sclerosis in Stockholm, Sweden: use of and satisfaction with care and the value of different factors in predicting use of care

BACKGROUND
The national strategy for treatment of chronic diseases - including MS - and changes in the Swedish welfare system, call for analyses of the use of, and patient satisfaction with, care in a long-term perspective. The aim was therefore to explore the use of care and the predictive value of personal factors, disease-specific factors and functioning on the use of care and to explore patient satisfaction with care in a 10-year perspective.


METHODS
Information regarding personal factors, disease-specific factors, functioning and satisfaction with care was collected by home-visits; use of care was collected from the Stockholm County Council computerised register.


RESULT
Data from 121 people with MS (PwMS) was collected. Primary care accounted for the majority of all care. Neurology and Rehabilitation Departments together accounted for two-thirds of all hospital outpatient care. Rehabilitation Departments accounted for one-third of the total number of inpatient days. Lower coping capacity, impaired manual dexterity and activity of daily living dependency at baseline, together with progress in MS disability predicted a higher use of care. Overall, patient satisfaction with care was stable over time.


CONCLUSION
The extensive use of care offers challenges to care coordination. Implementation of person-centred care could be a strategy to increase efficacy/outcome of care.
