The nervous system is composed of a large number of neurons, and the electrical activities of neurons can present multiple modes during the signal transmission between neurons by changing intrinsic bifurcation parameters or under appropriate external forcing. In this review, the dynamics for neuron, neuronal network is introduced, for example, the mode transition in electrical activity, functio...

Meliodosis is an infectious disease encountered mainly in tropics. It is not an uncommon problem in Malaysia especially in areas with agricultural activities. Although it can occur in all age groups, there have been few reported cases in children. Men are more commonly affected than women due to outdoor activities. Neonatal cases have been reported in Hawaii and Thailand. These infants presente...

I describe the rationale behind the introduction and practical details of implementing weekly workshops, recently introduced to replace traditional tutorial-plus-laboratory activities in a large introductory undergraduate physics course. The case for introducing these activities is made, together with their role in the course which has, over a period of several years, evolved into a blended mod...

The military logistics community requires a scalable, high fidelity simulation capability for modeling the detailed, dynamic, logistics activities of a distributed military organization. Furthermore, such detailed logistics simulations could be coupled with existing combat simulations to understand better the impact of logistics activities upon combat operations. BBN is developing a scalable, a...

Although many studies show that thromboxane A(2) (TXA(2)) has the action of gastrointestinal (GI) motility using GI muscle cells and tissue, there are no reports on the effects of TXA(2) on interstitial cells of Cajal (ICC) that function as pacemaker cells in GI tract. So, we studied the modulation of pacemaker activities by TXA(2) in ICC with whole cell patch-clamp technique. Externally applie...

AIMS For most elderly pacemaker patients, evaluation of rate-adaptive pacing using treadmill and bicycle tests is impractical and not representative of typical daily activities. This study was designed to compare the performance and physiological response of the closed-loop stimulation (CLS) rate-adaptive sensor to accelerometer (XL) and no rate sensor (DDD) during typical daily activity testin...

When mobiTopp was initially designed, more than 10 years ago, it has been the first travel demand simulation model intended for an analysis period of one week. However, the first version supported only an analysis period of one day. This paper describes the lessons learned while extending the simulation period from one day to one week. One important issue is ensuring realistic start times of ac...

In this paper we present a simple framework for activity recognition based on a model of multi-layered finite state machines, built on top of a low level image processing module for spatio-temporal detections and limited object identification. The finite state machine network learns, in an unsupervised mode, usual patterns of activities in a scene over long periods of time. Then, in the recogni...
