Research on the Stability of Plantar Pressure Under Normal Walking Condition

The plantar pressure of identity recognition in pattern recognition field has a certain application. Only each of the plantar pressure is stable, personalized, plantar pressure identification is scientific, but the stability problem of the plantar pressure has not been verified. In the public security practice footprints can be were personal identification, but there is no underlying scientific principles as the theoretical support. To process the collected data by computer programming, so as to prove the data of plantar pressure of normal person is basically stable. Use MATLAB software to conduct the dynamic plantar pressure's peak data table that acquired by FOOTSCAN plantar pressure measurement and analysis system, and use statistical correlation algorithm to deal with, so as to analysis the stability of plantar pressure quantitatively. Each one's feature point variance of plantar pressure is basically stable. The stability of plantar pressure data is better in normal human walking condition, so it can be used to study and apply by the plantar pressure data.
A Unified Approach to Estimating Demand and Welfare

The measurement of price changes, economic welfare, and demand parameters is currently based on three disjoint approaches: macroeconomic models derived from time invariant utility functions, microeconomic estimation based on time varying utility (demand) systems, and actual price and real output data constructed using formulas that differ from either approach. The inconsistencies are so deep that the same assumptions that form the foundation of demand system estimation can be used to prove that standard price indexes are incorrect, and the assumptions underlying standard exact and superlative price indexes invalidate demand system estimation. In other words, we show that extant micro and macro welfare estimates are biased and inconsistent with each other as well as the data. We develop a unified approach to demand and price measurement that exactly rationalizes observed micro data on prices and expenditure shares while permitting exact aggregation and meaningful macro comparisons of welfare over time. We show that all standard price indexes are special cases of our approach for particular values of the elasticity of substitution, constant preferences for each good, and a constant set of goods. In contrast to these standard index numbers, our approach allows us to compute changes in the cost of living that take into account both changes in the preferences for individual goods and the entry and exit of goods over time. Using barcode data for the U.S. consumer goods industry, we show that allowing for the entry and exit of products, changing preferences for individual goods, and a value for the elasticity of substitution estimated from the data yields substantially different conclusions for changes in the cost of living from standard index numbers.
Analysis of fog effects on terrestrial Free Space optical communication links
Venue: 2016 IEEE International Conference on Communications Workshops (ICC)

In this paper, we consider and examine fog measurement data, coming from several locations in Europe and USA, and attempt to derive a unified model for fog attenuation in free space optics (FSO) communication links. We evaluate and compare the performance of our proposed model to that of many well known alternative models. We found that our proposed model, achieves an average RMSE that outperforms them by more than 9 dB. Furthermore, we have studied the performance of the FSO system using different performance metrics such as signal to noise (SNR) ratio, bit error rate (BER) and channel capacity. Our results show that FSO is a short range technology. Therefore, FSO is expected to find its place in future networks that will have small cell size, i.e. ;1 km diameter. Moreover, our investigation shows that under dense fog, it is difficult to maintain a communications link because of the high signal attenuation, which requires switching the communications to RF backup. Our results show that increasing the transmitted power will improve the system performance under light fog. However, under heavy fog, the effect is minor. To enhance the system performance under low visibility range, multi hop link is used which can enhance the power budget by using short segments links. Using 22 dBm transmitted power, we obtained BER=10 3 over 1 km link length with 600 m visibility range which corresponds to light fog. However, under lower visibility range equals 40 m that corresponds to dense fog, we obtained the same BER but over 200 m link length.
Terlipressin Plus Albumin Is More Effective Than Albumin Alone in Improving Renal Function in Patients With Cirrhosis and Hepatorenal Syndrome Type 1.
Venue: Gastroenterology

Hepatorenal syndrome type 1 (HRS 1) in patients with cirrhosis and ascites is a functional, potentially reversible, form of acute kidney injury characterized by rapid <2 wk) and progressive deterioration of renal function. Terlipressin is a synthetic vasopressin analogue that acts, via vascular vasopressin V1 receptors, as a systemic vasoconstrictor. We performed a phase 3 study to evaluate the efficacy and safety of intravenous terlipressin plus albumin vs placebo plus albumin in patients with HRS 1.  Adult patients with cirrhosis, ascites, and HRS 1 (based on the 2007 International Club of Ascites criteria of rapidly deteriorating renal function) were assigned randomly to groups given intravenous terlipressin (1 mg, n 97) or placebo (n 99) every 6 hours with concomitant albumin. Treatment continued through day 14 unless the following occurred: confirmed HRS reversal (CHRSR, defined as 2 serum creatinine [SCr] values =1.5 mg/dL, at least 40 hours apart, on treatment without renal replacement therapy or liver transplantation) or SCr at or above baseline on day 4. The primary end point was the percentage of patients with confirmed CHRSR. Secondary end points included the incidence of HRS reversal (defined as at least 1 SCr value =1.5 mg/dL while on treatment) transplant free survival, and overall survival. The study was performed at 50 investigational sites in the United States and 2 in Canada, from October 2010 through February 2013.  Baseline demographic/clinical characteristics were similar between groups. CHRSR was observed in 19 of 97 patients (19.6% receiving terlipressin vs 13 of 99 patients (13.1% receiving placebo (P .22) HRS reversal was achieved in 23 of 97 (23.7% patients receiving terlipressin vs 15 of 99 (15.2% receiving placebo (P .13) SCr decreased by 1.1 mg/dL in patients receiving terlipressin and by only 0.6 mg/dL in patients receiving placebo (P .001) Decreases in SCr and survival were correlated (r(2) .882; P .001) Transplant free and overall survival were similar between groups. A significantly greater proportion of patients with CHRSR who received terlipressin survived until day 90 than patients who did not have CHRSR after receiving terlipressin (P .001) this difference was not observed in patients who did vs did not have CHRSR after receiving placebo (P .28) There were similar numbers of adverse events in each group, but patients in the terlipressin group had more ischemic events.  Terlipressin plus albumin was associated with greater improvement in renal function vs albumin alone in patients with cirrhosis and HRS 1. Patients had similar rates of HRS reversal with terlipressin as they did with albumin.
Clinical Scenarios in Acute Kidney Injury: Hepatorenal Syndrome.
Venue: Contributions to nephrology

Renal failure commonly occurs in patients affected by cirrhosis, especially when there is ascites. It is typically secondary to intercurrent events that can further compromise blood flow in conditions of relatively decreased renal perfusion. Hepatorenal syndrome (HRS) is a particular and common type of kidney failure that affects patients with liver cirrhosis or, less frequently, with fulminant hepatic failure. The syndrome is characterized by splanchnic vasodilation and renal vasoconstriction. The classification of HRS identifies 2 categories of kidney failure, known as type 1 and type 2 HRS, that occur in patients with either cirrhosis or fulminant hepatic failure.
Evaluation of the Effectiveness of Tai Chi versus Brisk Walking in Reducing Cardiovascular Risk Factors: Protocol for a Randomized Controlled Trial
Venue: International journal of environmental research and public health

Physical inactivity is one of the major modifiable lifestyle risk factors for cardiovascular disease (CVD) This protocol aims to evaluate the effectiveness of Tai Chi versus brisk walking in reducing CVD risk factors. This is a randomized controlled trial with three arms, namely, Tai Chi group, walking group, and control group. The Tai Chi group will receive Tai Chi training, which consists of two 60 min sessions each week for three months, and self practice for 30 min every day. The walking group will perform brisk walking for 30 min every day. The control group will receive their usual care. 246 subjects with CVD risk factors will be recruited from two outpatient clinics. The primary outcome is blood pressure. Secondary outcomes include fasting blood for lipid profile, sugar and glycated haemoglobin (HbA1c) body mass index, waist circumference, body fat percentage; perceived stress level and quality of life. Data collections will be conducted at baseline, 3 month, 6 month and 9 month. Generalized estimating equations model will be used to compare the changes in outcomes across time between groups. It is expected that both the Tai Chi and walking groups could maintain better health and have improved quality of life, and that Tai Chi will be more effective than brisk walking in reducing CVD risk factors.
Immersive Recommendation: News and Event Recommendations Using Personal Digital Traces
Venue: WWW

We propose a new user centric recommendation model, called Immersive Recommendation, that incorporates cross platform and diverse personal digital traces into recommendations. Our context aware topic modeling algorithm systematically profiles users' interests based on their traces from different contexts, and our hybrid recommendation algorithm makes high quality recommendations by fusing users' personal profiles, item profiles, and existing ratings. Specifically, in this work we target personalized news and local event recommendations for their utility and societal importance. We evaluated the model with a large scale offline evaluation leveraging users' public Twitter traces. In addition, we conducted a direct evaluation of the model's recommendations in a 33 participant study using Twitter, Facebook and email traces. In the both cases, the proposed model showed significant improvement over the state of the art algorithms, suggesting the value of using this new user centric recommendation model to improve recommendation quality, including in cold start situations.
Focal Flow: Measuring Distance and Velocity with Defocus and Differential Motion
Venue: ECCV

We present the focal flow sensor. It is an unactuated, monocular camera that simultaneously exploits defocus and differential motion to measure a depth map and a 3D scene velocity field. It does so using an optical flow like, per pixel linear constraint that relates image derivatives to depth and velocity. We derive this constraint, prove its invariance to scene texture, and prove that it is exactly satisfied only when the sensor's blur kernels are Gaussian. We analyze the inherent sensitivity of the ideal focal flow sensor, and we build and test a prototype. Experiments produce useful depth and velocity information for a broader set of aperture configurations, including a simple lens with a pillbox aperture.

L2 Learners' Enhanced Pragmatic Comprehension of Implicatures via Computer Mediated Communication and Social Media Networks

Second or foreign language (L2) learners' development of interlanguage pragmatic (ILP) competence to understand and properly interpret utterances under certain social and cultural circumstances plays a pivotal role in the achievement of communicative competence. The current study was designed to explore the effects of synchronous computer mediated communication (SCMC) and asynchronous computer mediated communication (ACMC) course modules delivered through social media networks (SMN) on the development of the Iranian L2 learners' comprehension of implicatures. The participants of the study were 90 English as aforeign language (EFL) undergraduate students attending three intact classes. The classes were randomly assigned to one control and two experimental (SCMC and ACMC) groups. An openended implicature comprehension test was used to assess students' ILP development in this pretest posttest comparison group study. The control group received the traditional teacherfronted instruction, and the S/ACMC groups received instruction via synchronous and asynchronous modules of SMNs for 4 months, respectively. Students' attitudes towards the CMC based courses were also sought. Split plot ANOVA results indicated that both experimental groups developed significant ILP ability to comprehend and interpret L2 implicatures after the instruction; however, by comparison, the ACMC group improved more considerably. It is concluded that, first, comprehending L2 implicatures is not impervious to computer mediated instruction and, second, different CMC affordances may result in differential ILP developmental effects in teaching L2 pragmatics. The findings can help L2 teachers decide how to use CMC affordances and SMN modules to raise L2 learners' pragmatic awareness.
Study Of The Prevalence Rate Of Bronchial Asthma Among The Secondary Schools Students In Ahad Rubaida City, District Abha, Assir Region, Saudi Arabia

The objective of this cross sectional study was to determine the prevalence rate of bronchial asthma among Saudi School boys (in three different schools,named Al Fauaz, Saffwan and Al Abana) at Ahad Rubaida city,district Abha,Assir region, Saudi Arabia. Another objective was to study and compare the prevalence of other allergenic diseases and environmental factors associated with bronchial asthma among asthmatic school boys and their families with their no asthmatics counterparts.  This was a cross sectional study. The methodology included the distribution of a self administered questionnaire which was filled by the 200 school boys and parents who satisfied the selection criteria of the study.  The prevalence rate of Questionnaire Diagnosed Asthma (QDA) were 95% for school boys and their parents suffered higher rates of allergenic diseases and environmental factors (passive smoking) than non Questionnaire Diagnosed Asthma (NQDA)  The prevalence of Questionnaire Diagnosed Asthma (QDA) among school boys in Ahad Rubaida city was less than those reported from other parts of the Kingdom but higher than the ones reported from Arab, developing and European countries. There is an evidence that a combination of genetic and environmental factors play a major role in the aetiology of this disease. Based on the results of this study, appropriate and practical measures need to be taken to identify causes and improve the control programs in the Ahad Rubaida city.
Asthma and other allergic diseases among Saudi schoolchildren in Najran: the need for a comprehensive intervention program
Venue: Annals of Saudi medicine

In the last three decades, an increasing incidence of allergic diseases has been associated with increasing morbidity and mortality in children and young adults.  The study aimed to investigate the prevalence and risk factors associated with allergic diseases among Saudi schoolchildren in the southwestern Saudi region of Najran, and to determine the sensitization of patients to a set of allergens.  Cross sectional observational study.  Primary, intermediate and secondary schools, Najran, Saudi Arabia.  All participants completed the Arabic version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Skin prick tests (SPT) were performed, using a panel of standardized allergenic extracts.  Prevalence and risk factors associated with pediatric allergic diseases.  The study included 1700 Saudi schoolchildren. The overall prevalence of physician diagnosed asthma, allergic rhinitis and atopic dermatitis was 27.5% 6.3% and 12.5% respectively. Multivariate analysis showed that male gender (adjusted odds ratio [aOR] 1.27) fast food consumption (aOR, 1.53) trucks passing near houses (aOR, 1.86) and having a dog or cat at home (aOR, 1.85) were significant risk factors. A total of 722 (42.5% children had a positive SPT result to at least one allergen. The most prevalent allergens were grass pollens (60% cat fur (41.6% and house dust mites (25%  The findings of this study highlight the urgent need for developing an effective intervention program including several components working in harmony to control and reduce the burden of allergic diseases.  These results may not be generalizable to the rest of Saudi Arabia.
A review on polycyclic aromatic hydrocarbons: Source, environmental impact, effect on human health and remediation

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants generated primarily during the incomplete combustion of organic materials (e.g. coal, oil, petrol, and wood) Emissions from anthropogenic activities predominate; nevertheless, some PAHs in the environment originate from natural sources such as open burning, natural losses or seepage of petroleum or coal deposits, and volcanic activities. Major anthropogenic sources of PAHs include residential heating, coal gasification and liquefying plants, carbon black, coal tar pitch and asphalt production, coke and aluminum production, catalytic cracking towers and related activities in petroleum refineries as well as and motor vehicle exhaust. PAHs are found in the ambient air in gas phase and as sorbet to aerosols. Atmospheric partitioning of PAH compounds between the particulate and the gaseous phases strongly influences their fate and transport in the atmosphere and the way they enter into the human body. The removal of PAHs from the atmosphere by dry and wet deposition processes are strongly influenced by their gas/particle partitioning. Atmospheric deposition is a major source for PAHs in soil. Many PAHs have toxic, mutagenic and/or carcinogenic properties. PAHs are highly lipid soluble and thus readily absorbed from the gastrointestinal tract of mammals. They are rapidly distributed in a wide variety of tissues with a marked tendency for localization in body fat. Metabolism of PAHs occurs via the cytochrome P450 mediated mixed function oxidase system with oxidation or hydroxylation as the first step. Several different remediation technologies have been tested in efforts to remove these environmental contaminants. Among them, bioremediation is showing particular promise as a safe and cost effective option. In spite of their xenobiotic properties, a variety of genera of gram positive and negative bacteria, fungi and algae have been isolated and characterized for their ability to utilize PAHs. The aim of this review is to discuss PAHs impact on the environmental and the magnitude of the human health risks posed by such substances. They also contain important information on concentrations, burdens and fate of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere. The main anthropogenic sources of PAHs and their effect on the concentrations of these compounds in air are discussed. The fate of PAHs in the air, their persistence and the main mechanisms of their losses are presented. Health hazards associated with PAH air pollution are stressed.
