韩国数学家解开60年之久的生物钟秘密
韩国数学家 生物钟秘密
2015/12/21
据韩国东亚日报报道,韩国科学技术院(KAIST)数理科学系教授金在景利用数学模型,解开了即使温度改变,生物钟也会按时运作的原理,引起人们关注。生物钟起到维持24小时周期的生物节律的作用,晚上9点左右开始分泌睡眠荷尔蒙“将黑素”,提醒人们睡觉,早上7点左右会让人醒来。但是普通的生物化学反应,随着温度上升,反应速度也会加快。也就是说,身体发热或在夏季,睡眠时间可能会缩短。幸运的是,人体生物钟与温度变化...

Gene expression patterns of breast carcinomas distinguish tumor subclasses with clinical implications
Gene expression patterns breast carcinomas tumor subclasses clinical implications
2015/8/21
The purpose of this study was to classify breast carcinomas based on variations in gene expression patterns derived from cDNA microarrays and to correlate tumor characteristics to clinical outcome. A ...

There are various types of classifiers that can be trained on gene expression data with class labels. Many of them have an embedded mechanism for feature selection, by which they distinguish a subset ...
Using multivariate adaptive regression splines to predict the distributions of New Zealand’s freshwater diadromous fish
distribution environment fish fresh-water MARS
2015/8/21
Relationships between probabilities of occurrence for fifteen diadromous fish species and environmental variables characterising their habitat in fluvial waters were explored using an extensive collec...
Variation in demersal fish species richness in the oceans surrounding New Zealand:an analysis using boosted regression trees
Demersal fish Species richness Boosted regression trees Statistical model
2015/8/21
We analysed relationships between demersal fish species richness, environment and trawl characteristics using an extensive collection of trawl data from the oceans around New Zealand. Analyses were ca...
Penalized Logistic Regression for Detecting Gene Interactions
Penalized Logistic Regression Detecting Gene Interactions
2015/8/21
We propose using a variant of logistic regression with L2 regularization to fit genegene and gene-environment interaction models. Studies have shown that many common diseases are influenced by interac...
