Gastrointestinal neuromuscular diseases are a clinically heterogeneous group of disorders of children and adults in which symptoms are presumed or proven to arise as a result of neuromuscular (including interstitial cell of Cajal) dysfunction. Common to most of these diseases are symptoms of impaired motor activity which manifest as slowed or obstructed transit with or without evidence of transient or persistent radiological visceral dilatation. A variety of histopathological techniques and allied investigations are being increasingly applied to tissue biopsies from such patients. This review outlines some of the more recent advances in this fi eld, particularly in the most contentious area of small bowel disease manifesting as intestinal pseudo-obstruction.

It is our purpose in this paper to show that some results obtained in uniformly convex real Banach space with uniformly Gateaux differentiable norm are extendable to more general reflexive and strictly convex real Banach space with uniformly G＆teaux differentiable norm. Demicompactness condition imposed in such results is dispensed with. Furthermore, Applications of our theorems to approximation of common fixed point of countable infinite family of continuous pseudocontractive mappings and approximation of common solution of countable infinite family of generalized mixed equilibrium problems are also discussed. Our theorems improve, generalize, unify and extend several recently announced results.

Thermodynamic concepts required for the thermodynamic calculation of the potentials of electrodes for high temperature applications are briefly reviewed. A thermodynamic approach to the calculation of half cell potentials and the standard chemical potential of an electron at high temperatures which are related to the Standard Hydrogen electrode(SHe) is discussed. As examples, an external Ag/AgCl reference electrode and a YSZ(Ag|O_2) pH sensor for high temperature applications are analyzed by using the thermodynamic approach to derive a high temperature pH measurement equation. The two electrodes are employed to measure high temperature pH and the measured pH was compared with the calculated pH by using a solution chemistry method. Concepts and principles for electrode kinetics are also briefly introduced and a modification to the Tafel equations is suggested.

To investigate the effect of different environmental conditions of GFRP bars in concrete beams with work cracks subjected to sustained loads, the beams were exposed in indoor, freeze/thaw cycles and immersed in alkaline solution at elevated temperature. The bars were carefully extracted from the beams and tested in order to evaluate residual tensile properties. The results show that the tensile strength decreased significantly in the highly aggressive conditions but not in the natural conditions. The effect of GFRP bars casting in concrete beams demonstrated approximately 2.5% decrease of tensile strength caused by pore water environment in concrete beams on basis of those of the original bars. The effect of sustained loading plus work cracks demonstrated about 10.5% tensile strength decrease on basis of those of the bars only casted in concrete beams. The effect of environments under sustained loading plus work cracks demonstrated about 17% tensile strength decrease caused by a saturated solution of Ca（OH）2 and 60-2 ℃ tap water （pH=12-13） and about 8% tensile strength decrease caused by freezing and thawing cycle （F/T）, both on basis of those of the bars of the indoor beams only under sustained loading plus work cracks. The results demonstrate the effects of the tensile strengths under different environmental conditions of GFRP bars in concrete beams with work cracks subjected to sustained loads.

electron microscopy(eM)provides a unique ability to visualize structural detail with a resolution orders of magnitude better than other imaging *** conventionally,its limitation is that each acquired image represents a small area with a section thickness significantly less than 100 ***,techniques have been developed that allow thousands of relatively large serial-sections to be collected and efficiently imaged at full eM resolution,with the images then being stitched back together to produce a 3D volume.

Advanced driver assistance systems(ADAS) seek to provide drivers and passengers of automotive vehicles increased safety and comfort. Original equipment manufacturers are integrating and developing systems for distance keeping, lane keeping and changing and other functionalities. The modern automobile is a complex system of systems. How the functionalities of advanced driver assistance are implemented and coordinated across the systems of the vehicle is generally not made available to the wider research community by the developers and manufactures. This paper seeks to begin filling this gap by assembling open source physics models of the vehicle dynamics and ADAS command models. Additionally, in order to facilitate ADAS development and testing without having access to the details of ADAS, a coordinated control architecture for motion management is also proposed for distributing ADAS motion control commands over vehicle systems. The architecture is demonstrated in a case study where motion is coordinated between the steering and the braking systems, which are typically used only for a single functionality. The integrated vehicle and system dynamics using the coordinated control architecture are simulated for various driving tasks. It is seen that improved trajectory following can be achieved by the proposed coordinated control architecture. The models, simulations and control architecture are made available for open access.

In 2011, the University of Pittsburgh School of Medicine(UPSOM) and Tsinghua University formed a partnership to further the education of Tsinghua medical students. These students come to UPSOM as visiting research scholars for two years of their eight-year MD curriculum. During this time, the students, who have completed four years at Tsinghua, work full-time in medical school laboratories and research programs of their choice, essentially functioning as graduate students. In their first two months in Pittsburgh, the scholars have a one-week orientation to biomedical research, followed by two-week rotations in four labs selected on the basis of the scholars' scientific interests, after which they choose one of these labs for the remainder of the two *** labs may be in basic science departments, basic science divisions of clinical departments, or specialized centers that focus on approaches like simulation and modeling. The Tsinghua students also have a brief exposure to clinical medicine. UPSOM has also formed a similar partnership with Central South University Xiangya School of Medicine in Changsha, Hunan Province. The Xiangya students come to UPSOM for two years of research training after their sixth year and, thus, unlike the Tsinghua students,have already completed their clinical rotations. UPSOM faculty members have also paved the way for UPMC(University of Pittsburgh Medical Center), UPSOM's clinical partner, to engage with clinical centers in China. Major relationships involving advisory, training, managerial, and/or equity roles exist with Xiangya International Medical Center, KingMeD Diagnostics, First Chengmei Medical Industry Group, and Macare Women's Hospital. Both UPSOM and UPMC are actively exploring other clinical and academic opportunities in China.
