□ 生命は複雑系事象の網目を織り成す紐の絡まった結び目のようなもの。解けても何処かに消えるわけでなく、繋がりが変わるだけ。

思考や感情は、発語することで縺れ合う情報繊維を解いて、励起状態から電気的負荷を発散しエントロピーを保つ。では入力を隔絶された孤独な観測者はどうなるか。内部循環と自己摂動。その夢は入れ子の宇宙そのものの姿である。


言語は、現実空間を概念的に可換な発語認識の境界面を規定する。そして言語は共有によってしか発達せず、生物学的空間と共進化する。言語に規定された信号処理ベースの計算は自ずから観測者の行動を制約付きでアフォードし、認知の至る限界を前提している。

PLoSCompBiol:
Adjusting Phenotypes by Noise Control dx.plos.org/10.1371/journa…

Our analysis is readily applicable to various types of noise control and to different types of system; for example, we can orthogonally control the mean and noise levels and can control system dynamics such as noisy oscillations. As an illustration we applied our method to HIV and yeast gene expression systems and metabolic networks. The oscillatory signal control was applied to p53 oscillations from DNA damage.

Furthermore, we showed that the efficiency of orthogonal control can be enhanced by applying extrinsic noise and feedback. Our noise control analysis can be applied to any stochastic model belonging to continuous time Markovian systems such as biological and chemical reaction systems, and even computer and social networks. We anticipate the proposed analysis to be a useful tool for designing and controlling synthetic gene networks.

This independence was shown to be rooted to a certain network structure satisfying Feinberg's deficiency zero theorem [24]?[26]. We will show that when such species independence occurs, the orthogonal control of mean and noise levels is not possible, but that the application of extrinsic noise or feedback could help achieve orthogonal control.

□ Amazon Rolls out NoSQL Database Servicein the cloud called DynamoDB

>> http://www.genomeweb.com//node/1016…
>> DynamoDB

Amazon Web Services (AWS) has launched a fully managed NoSQL database service in the cloud called DynamoDB that aims to provide seamless scalability on the fly. AWS is claiming that their new service will offload administrative tasks such as hardware provisioning, setup, configuration, replication, software patching, and cluster scaling.

AWSがDynamoDB上でNoSQLサービス開始。分散システム基盤の超スケーラブル データベース。NoSQLは厳密なスキーマが無く、オミックス分野で有意な計算効率を発揮。

□ Revealing stable processing products from ribosome-associated small RNAs by deep-sequencing data analysis

>> http://t.co/noBohY2n

APART, a novel automated computational pipeline, providing a complete workflow for the reliable detection of RNA processing products from next-generation-sequencing data. The major features include efficient handling of non-unique reads, detection of novel stable ncRNA transcripts and processing products and annotation of known transcripts based on multiple sources of information.

To disclose the potential of APART, we have analyzed a cDNA library derived from small ribosome-associated RNAs in Saccharomyces cerevisiae. By employing the APART pipeline, we were able to detect and confirm by independent experimental methods multiple novel stable RNA molecules differentially processed from well known ncRNAs, like rRNAs, tRNAs or snoRNAs, in a stress-dependent manner.

□ MATS: a Bayesian framework for flexible detection of differential alternative splicing from RNA-Seq data

>> http://bit.ly/wgRAJp

Ultra-deep RNA sequencing has become a powerful approach for genome-wide analysis of pre-mRNA alternative splicing. We develop MATS (multivariate analysis of transcript splicing), a Bayesian statistical framework for flexible hypothesis testing of differential alternative splicing patterns on RNA-Seq data.

MATS uses a multivariate uniform prior to model the between-sample correlation in exon splicing patterns, and a Markov chain Monte Carlo (MCMC) method coupled with a simulation-based adaptive sampling procedure to calculate the P-value and false discovery rate (FDR) of differential alternative splicing. Importantly, the MATS approach is applicable to almost any type of null hypotheses of interest, providing the flexibility to identify differential alternative splicing events that match a given user-defined pattern.

Fine-Scale Temporal Dynamics of a Fragmented Lotic Microbial Ecosystem: Microbial ecosystemsbit.ly/ADIwzS
Scaling is an important concept in landscape ecology, where it is usually used in a geographical, rather than temporal perspective34. A lesson from experiment described in this study is that a bacterial community can change drastically and rapidly and yet have an equally rapid recovery. Our data emphasize the need for a re-evaluation of the time scale of microbial sampling experiments beyond diurnal cycles, especially in dynamic environments such as fresh water streams, lakes and irrigated soil.

□ Differential network biology

>> bit.ly/xVGJYw

Here, we review the technological developments and experimental designs that have enabled differential network mapping at very large scales and highlight biological insight that has been derived from this type of analysis. We argue that differential network mapping, which allows for the interrogation of previously unexplored interaction spaces, will become a standard mode of network analysis in the future, just as differential gene expression and protein phosphorylation studies are already pervasive in genomic and proteomic analysis.

Single-celled #organism can evolve multicellularity within months bit.ly/zTl26q
The origin of multicellular life, one of the most important developments in Earth’s history, could have occurred with surprising speed, US researchers have shown. In the lab, a single-celled yeast (Saccharomyces cerevisiae) took less than 60 days to evolve into many-celled clusters that behaved as individuals. The clusters even developed a primitive division of labour, with some cells dying so that others could grow and reproduce.

Review (in GWAS Series). G. Gibson on 20 arguments for and vs two main models for the genetic basis of complex traits: bit.ly/wKWAOd
Genome-wide association studies have greatly improved our understanding of the genetic basis of disease risk. The fact that they tend not to identify more than a fraction of the specific causal loci has led to divergence of opinion over whether most of the variance is hidden as numerous rare variants of large effect or as common variants of very small effect. Here I review 20 arguments for and against each of these models of the genetic basis of complex traits and conclude that both classes of effect can be readily reconciled.

[Editorial] Addiction?a global problem with no global solution bit.ly/zbTYE5
international drug conventions protect public health, or otherwise, and concludes that national policies aligned with risks of different drugs are needed. The authors state: “The cultural positions of different drugs vary enough to preclude universal policies on how to deal with all illicit or indeed licit drugs. From the perspective of public health, we need to move towards a control system that is more aligned with the risks that different drugs pose to users and shows an understanding of the effects of different regulatory approaches on drug use and harm.”

□ sFFT: Sparse Fast Fourier Transform

>> http://groups.csail.mit.edu/netmit/sFFT/

We consider the sparse Fourier transform problem: given a complex vector x of length n, and a parameter k, estimate the k largest (in magnitude) coefficients of the Fourier transform of x. The problem is of key interest in several areas, including signal processing, audio/image/video compression, and learning theory.

We propose a new algorithm for this problem. The algorithm leverages techniques from digital signal pro- cessing, notably Gaussian and Dolph-Chebyshev filters. The resulting algorithm is structurally simpler than its predecessors. As a consequence, we are able to extend considerably the range of sparsity, k, for which the algorithm is faster than FFT, both in theory and practice.
