BACKGROUND Lactic acid bacteria (LAB) are important in the food industry for the production of fermented food products and in human health as commensals in the gut. However, the phylogenetic relationships among LAB species remain under intensive debate owing to disagreements among different data sets. RESULTS We performed a phylogenetic analysis of LAB(More)
BACKGROUND The ongoing rise in the prevalence of hypertension in children and adolescents is considered to be accompanied with the epidemic of childhood overweight and obesity. In this study, we established a large scale cross-sectional study in Shanghai, China, which presented a new evidence for the correlation of hypertension prevalence with overweight(More)
Elucidating gut microbiota among gallstone patients as well as the complex bacterial colonization of cholesterol gallstones may help in both the prediction and subsequent lowered risk of cholelithiasis. To this end, we studied the composition of bacterial communities of gut, bile, and gallstones from 29 gallstone patients as well as the gut of 38 normal(More)
In this paper, an approximated-based adaptive fuzzy control approach with only one adaptive parameter is presented for a class of single input single output strict-feedback nonlinear systems in order to deal with phenomena like nonlinear uncertainties, unmodeled dynamics, dynamic disturbances, and unknown time delays. Lyapunov-Krasovskii function approach(More)
Security is an emerging topic in the field of embedded devices. ARM TrustZone is a technology used to increase security of embedded systems using the ARM processor, the most common processor for embedded consumer devices. Trustzone is a hardware isolation mechanism that improves software security without the need for extra hardware chips. It separates(More)
BACKGROUND There has been no effective method to monitor the changes of blood coagulation after thromboprophylaxis for elective arthroplasty patients. The objective of this study is to assess the coagulation status of patients undergoing arthroplasty with thromboelastograph (TEG). METHODS Ninety patients undergoing primary elective unilateral arthroplasty(More)
Object visual tracking and servo is a challenging research topic in the fields of computer vision, pattern recognition and robotics. Usually, people just utilize PTZ for active surveillance tracking. In this work, we combine visual tracking and visual servo to drive a PTZ to cast laser beam on the target object. The demonstrated tracking system is(More)
