BACKGROUND Glucagon-like peptide-1 and its receptor agonist-exendin-4 (Ex-4) have been shown to provide beneficial effects for cardiovascular diseases. This study investigated the effects of Ex-4 on ischemia-induced ventricular arrhythmias in rats. METHODS Anesthetized male rats were once treated with Ex-4 (5 μg/kg, i.v.) 1 h before ischemia in the(More)
Purple potatoes were used as raw material to study the purple potato wine production process and antioxidant activity. This paper analyzed different fermentation time, fermentation temperature, yeast inoculum, initial pH, the initial sugar content on alcohol and anthocyanin contents of purple potato wine by single factor experiments and response surface(More)
There are many identical cascaded power units in voltage sourced converter (VSC) based on cascaded H-bridge or cascaded half-bridge, and the capacitor voltage balance is an important issue in them. The capacitor voltage in every power unit should be monitored on-line, which needs a versatile system to collect capacitor voltage. This paper proposes an(More)
Based on the complexity of the construction machinery system and the complicated characteristics of its reliability analysis, we put Bayesian Network to use in reliability analysis. Taking construction machinery engine as an example, the first thing to do is to construct a Fault Tree of engine system; then, a Bayesian Network model of reliability assessment(More)
The paper proposes an object detection algorithm based on the deformable part models, and integrates the idea of global and local information to improve the accuracy and robustness of target detection. Firstly, we train the pyramid HOG feature of the sample images and get the feature representation containing the root model, component model and the(More)
A new retrieval algorithm based on the texture-spatial texture using the GHM multiwavelets is presented. In order to describe the important visual information of image, we design the improved multiwavelets quantization map that can depict the important visual information for the multiwavelets sub-bands. Furthermore, the visual spatial histogram of(More)
We present a new empirical C-band cross-polarization ocean backscatter model for high wind retrievals, from ENVISAT-ASAR. The model relates normalized radar cross section (NRCS) in cross-polarization (VV/VH) to the wind speed at 10-m height. This wind retrieval model has the remarkable characteristic that it is independent of SAR radar incidence angles or(More)
This paper proposes a mathematical model for supply chain versus supply chain competition with customer preference. The model is based on stochastic user equilibrium and spatial price equilbirum theory with customer choice preference given by Logit model. We present a numerical example for illustrative purpose and provide conclusion remarks.
