Finding finer functions for partially characterized proteins by protein-protein interaction networks

Based on high-throughput data, numerous algorithms have been designed to find functions of novel proteins. However, the effectiveness of such algorithms is currently limited by some fundamental factors, including (1) the low a-priori probability of novel proteins participating in a detailed function; (2) the huge false data present in high-throughput datasets; (3) the incomplete data coverage of functional classes; (4) the abundant but heterogeneous negative samples for training the algorithms; and (5) the lack of detailed functional knowledge for training algorithms. Here, for partially characterized proteins, we suggest an approach to finding their finer functions based on protein interaction sub-networks or gene expression patterns, defined in function-specific subspaces. The proposed approach can lessen the above-mentioned problems by properly defining the prediction range and functionally filtering the noisy data, and thus can efficiently find proteins’ novel functions. For thousands of yeast and human proteins partially characterized, it is able to reliably find their finer functions (e.g., the translational functions) with more than 90% precision. The predicted finer functions are highly valuable both for guiding the follow-up wet-lab validation and for providing the necessary data for training algorithms to learn other proteins.     

英汉词汇搭配现象的异同比较

语言中能够独立运用的最小表义单位是词,因为词是“语言的最小的独立运用的意义单位”。对词汇搭配的研究是研究词的一个基本的重要内容,汉语和英语两种语言搭配有各自的特点,同时,二者也有共同之处。通过研究汉英词汇搭配中的某些现象,比较二者的相似与不同之处,旨在揭示英汉两种语言在语法规律以及语义范围等方面的特殊规律,对英语教学和翻译研究有一定的指导意义。     

ZrO_2纳米微粒红外振动特征

测定了单斜ＺｒＯ_２纳米材料在各种粒度下的付里叶变换红外光声光谱（ＦＴ—ＩＲ—ＰＡＳ），发现随粒度的减小，大部分的谱线位置蓝移，而有些谱线的位置红移，同时在不同频段，有的强度增强，有的强度减弱甚至消失。研究了量子尺寸效应和介电限城效应对其光学特征的影响，对观察到的物理现象进行了物理机制探讨

氯在Cu(100)面上的吸附及其对氧共吸附的影响的电子能谱研究

利用UPS、XPS、AES、△φ和热脱附等方法,研究了室温、低分压下氯在Cu(100)面上的吸附行为以及它对氧共吸附的影响。氯解离化学吸附在铜表面上,其吸附过程包括初始快速吸附,然后缓慢增加至饱和两个步骤。吸附引起铜表面轻微氧化,但表面没有重排,即使升温氯原子也没有进一步向下扩散,热脱附的唯一产物是氯原子。室温下,氯的预吸附降低甚至完全阻止了氧的接续吸附;而预吸附氧至饱和也不会阻碍氯的接续吸附,氯的接续吸附促使氧原子进入体相和铜原子向表层扩散。     

小麦群体连续选择效应的综合分析

本试验对由信谷核不育基因构成的异效群体内４个性状进行连续两轮歧化选择，并将所得数据进行群体综合分析。结果表明：整个群体的平均表现和变异程度未发明显变化；但群体分布状况有一定改变，尤其是每穗粒数的分布数化较为明显；株高和千粒重的有效因子数估计基本符合小麦遗传实际表现，每穗粒数的有效有效因子数估计略低，说明此性状遗传背景较为简单。

Illustrations with Real Examples of Using Ecological Regulation Strategies Against Crop Pests in China

In this paper, a series of examples from China, including those using ecological regulation strategies successfully to keep crop pests under control and those making more damages of crop pests caused by wrong cropping systems, crop distributions or extensive cultivation, were given and analyzed. From these, two pieces of experience were enlightened as follows： the first, the refoms of cropping systems and crop distributions must be beneficial to pest control or at least not increase the damage of crop pests; the second, we should further clarify the relationship between population dynamics of pests and cropping system/crop distribution, the basis for correctly laying down the ecological regulation systems.
