Minimum information about a microarray experiment (MIAME)-toward standards for microarray data.

Microarray analysis has become a widely used tool for the generation of gene expression data on a genomic scale. Although many significant results have been derived from microarray studies, one limitation has been the lack of standards for presenting and exchanging such data. Here we present a proposal, the Minimum Information About a Microarray Experiment (MIAME), that describes the minimum information required to ensure that microarray data can be easily interpreted and that results derived from its analysis can be independently verified. The ultimate goal of this work is to establish a standard for recording and reporting microarray-based gene expression data, which will in turn facilitate the establishment of databases and public repositories and enable the development of data analysis tools. With respect to MIAME, we concentrate on defining the content and structure of the necessary information rather than the technical format for capturing it.

高容量温盘驱动器伺服码同步时钟录写技术

提出了可变频时钟写入方法和锁相环倍频时钟写入方法，给出了这两种写入法的读／写电路，并分析了其性能。结果证明，可变频时钟写入方法电路简单，刻写时钟周期短；锁相环倍频时钟写入过程较前者长，但其频率范围容易调整。两者均适合高密度小型温盘的时钟录写。

以分析法比较流体的换热性能

基于换热过程中的损失率能定量地反映该过程中流体的传热与流动的综合性能这一特性，借助换热过程的损失率方程，分析比较了几种流体工质在不同换热方式下的综合特性。比较结果表明，液体（如水）有远优于气体（如空气）的流动与传热的综合性能，且随着流体温度的升高其优势更为明显。同时表明分析法在定量评价换热工质性能的突出特点及工程上的应用价值。

Towards sustainability in world fisheries

Fisheries have rarely been 'sustainable'. Rather, fishing has induced serial depletions, long masked by improved technology, geographic expansion and exploitation of previously spurned species lower in the food web. With global catches declining since the late 1980s, continuation of present trends will lead to supply shortfall, for which aquaculture cannot be expected to compensate, and may well exacerbate. Reducing fishing capacity to appropriate levels will require strong reductions of subsidies. Zoning the oceans into unfished marine reserves and areas with limited levels of fishing effort would allow sustainable fisheries, based on resources embedded in functional, diverse ecosystems.
