The present study was designed to determine the capability of human renal proximal tubule (RPT) to generate and export guanosine cyclic 3', 5' monophosphate (cGMP) in response to direct stimulation of soluble guanylyl cyclase by nitric oxide (NO) donors. In addition, we investigated whether cGMP extrusion from human RPT cells is required for inhibition of cellular sodium uptake. RPT cells were ...

This paper deals with the problem of tracking football players in a football match using data from a single moving camera. Tracking footballers from a single video source is di cult: not only do the football players occlude each other, but they frequently enter and leave the camera's eld of view, making initialisation and destruction of a player's tracking a di cult task. The system presented h...

Tracking is an important processing step for many single and multi-camera applications such as sports video analysis, traffic monitoring and event detection. In the first part of the paper, we present a framework of visual tracking using first-order Markov state-space model. We subsequently use Sequential importance Sampling method to estimate the posterior density and obtain the firstorder par...

To improve the precision of three-dimensional hand tracking based on the particle filtering, a novel algorithm using Multi-Model fusion to improve the state prediction of particle filtering is put forward. Through analyzing the experimental data of the virtual interactive platform system, combining with the behavior understanding and description of hand, we firstly construct a model for human h...

SpecMAT is a magnetic active target (AT) for transfer reaction studies with low-intensity radioactive ion beams at the ISOLDE facility (CERN). combines two types of detectors: gas-filled time projection chamber (TPC), core detector tracking charged particles emitted in nuclear reactions, and an array auxiliary scintillation detectors in-flight γ-ray spectroscopy. All components are optimised op...

population level by altering the infectiousness of vaccinated individuals who become infected. A vaccine trial design that does not estimate both susceptibility and infectiousness might reject a proposed vaccine that is capable of halting the HIV epidemic. We describe a vaccine trial design called the Retrospective Partner Trial (RPT), which can quantify vaccine effects on both susceptibility a...

In this paper, a novel and effective formulation based on isogeometric approach (IGA) and Refined Plate Theory (RPT) is proposed to study the behavior of laminated composite plates. Using many kinds of higher-order distributed functions, RPT model naturally satisfies the traction-free boundary conditions at plate surfaces and describes the non-linear distribution of shear stresses without requi...

Visual tracking of humans or objects in motion is a challenging problem when observed data undergo appearance changes (e.g., due to illumination variations, occlusion, cluttered background, etc.). Moreover, tracking systems are usually initialized with predefined target templates, or trained beforehand using known datasets. Hence, they are not always efficient to detect and track objects whose ...
