This paper describes the voice source localization algorithm used in the PictureTel automatic camera pointing system (LimeLight T M , Dynamic Speech Locating Technology). The system uses an array of 46cm wide and 30cm high, which contains 4 microphones, and is mounted on top of the monitor. The three dimensional position of a sound source is calculated from(More)
Excessive inflammation and tumour-necrosis factor (TNF) synthesis cause morbidity and mortality in diverse human diseases including endotoxaemia, sepsis, rheumatoid arthritis and inflammatory bowel disease. Highly conserved, endogenous mechanisms normally regulate the magnitude of innate immune responses and prevent excessive inflammation. The nervous(More)
Spatial uncertainty and undersampling are two of the major hypotheses for the losses of amblyopic spatial vision. To test these two hypotheses, equivalent spatial uncertainty and spatial integration efficiency in spatial position judgments were quantified with a spatial perturbation paradigm. Specifically, three-line bisection thresholds were measured for(More)
1. ABSTRACT Until today most cities of china have developed their own cadastral systems and more cities will develop in the future. And then there is a big problem with the communication and information share of these cadastral systems. There are two basic reasons to this question. The first one is that the systems are supposed to base on different(More)
This review outlines the mechanisms underlying the interaction between the nervous and immune systems of the host in response to an immune challenge. The main focus is the cholinergic anti-inflammatory pathway, which we recently described as a novel function of the efferent vagus nerve. This pathway plays a critical role in controlling the inflammatory(More)
There are multiple sources of reactive oxygen species (ROS) in the cell. As a major site of ROS production, mitochondria have drawn considerable interest because it was recently discovered that mitochondrial ROS (mtROS) directly stimulate the production of proinflammatory cytokines and pathological conditions as diverse as malignancies, autoimmune diseases,(More)
Tanshinone IIA (Tan IIA) is a major compound extracted from a traditional herbal medicine Salvia miltiorrhiza BUNGE, which is used to treat cardiovascular diseases, cerebrovascular diseases and postmenopausal syndrome. It has also been shown to possess anti-inflammatory activity. Since Tan IIA has a similar structure to that of 17beta-estradiol (E(2)), the(More)
We develop an Eulerian–Lagrangian localized adjoint method (ELLAM) to solve two-dimensional advection-diffusion equations with all combinations of inflow and outflow Dirichlet, Neumann, and flux boundary conditions. The ELLAM formalism provides a systematic framework for implementation of general boundary conditions, leading to mass-conservative numerical(More)
