摘要： The goal of this paper is to investigate total-cross-tied (TCT) configuration under partial shading condition. A full investigation requires mathematical analysis and simulation. An accurate mathematical analysis gives us a better understanding of how partial shading affects the output curves of the solar cell, so we first mathematically analyze the TCT (2 x 2) configuration under different partial shading conditions and then we check the mathematically analysis accuracy through Matlab simulation. All of the simulations in this paper are conducted using Matlab. We have used single diode solar cell model for mathematical analysis and the simulations. So we will explain how to acquire single diode solar cell model and its effective parameters. The better performance of TCT configuration among other configurations is why we have chosen this configuration to investigate under partial shading condition. The superiority of TCT configuration to other configurations like Honey-comp (HC), Bridge-linked (BL) and Series-parallel (SP) under different partial shading conditions is demonstrated and various aspects of these configurations in terms of output characteristics (maximum output power and power dissipation percentage) is displayed using Matlab simulation. All of the required inputs for simulations are extracted from standard photovoltaic cell datasheets. (C) 2016 Elsevier Ltd. All rights reserved.

摘要： Histamine and serotonin are neuromodulators which facilitate numerous, diverse neurological functions. Being co-localized in many brain regions, these two neurotransmitters are thought to modulate one another's chemistry and are often implicated in the etiology of disease. Thus, it is desirable to interpret the invivo chemistry underlying neurotransmission of these two molecules to better define their roles in health and disease. In this work, we describe a voltammetric approach to monitoring serotonin and histamine simultaneously in real time. Via electrical stimulation of the axonal bundles in the medial forebrain bundle, histamine release was evoked in the mouse premammillary nucleus. We found that histamine release was accompanied by a rapid, potent inhibition of serotonin in a concentration-dependent manner. We developed mathematical models to capture the experimental time courses of histamine and serotonin, which necessitated incorporation of an inhibitory receptor on serotonin neurons. We employed pharmacological experiments to verify that this serotonin inhibition was mediated by H-3 receptors. Our novel approach provides fundamental mechanistic insights that can be used to examine the full extent of interconnectivity between histamine and serotonin in the brain.

摘要： 在高中数学解题的过程中,数学分析思想是老师应该着重培养学生的思想,这比不断的教学生每段数学题的解法,要重要得多.数学分析思想主要包括五种思想,分别是：函数与方程思想、数形结合的思想、分类讨论思想、极限思想、特殊与一般思想.目前,在我国的大部分高中,十分注重培养学生的数学分析思想能力,这样可以使学生在大量的解题训练中,摸索到适合自己解题的思路,学生可以用不同方法来解答题目.
