Linked Dataのようなデータ運用技術が、国家・民族間の紛争を解決するのに必要なのではないかと昔から考えている。どの組織が問題で、誰が味方で、潜在するリスクと、その時間的推移や定量的評価までマッピング。資金やバジェットのトラフィックも可視化など、相互不信の払拭に特化するツールを開発する。

注意すべきは情報を掲示するだけの「ソース」になってはいけないということ。「市民が運用する」常時オープンで可視化され、そのデータの流入量や変質を見渡せるリテラシーのフレームワークを確立する(或はその部分をシステム側に担保出来るのが理想)。アジテートや不正操作を判別する自律した機械学習機能も実装していなければならない。


最終的には、国・政府・産業というものの機能や意思決定の一部、または数割をOpen Governmentの域を超えて、民間の取り組みや連携が代替していくことも視野に入れていかなければならない。縦割りの日本社会ですら、トップダウン型の体制では対処出来る問題があまりにも広域・細分化し機能不全。

mashable: 『神の素粒子』ヒッグス・ボゾン発見か?CERNが13日に緊急記者会見へ
Scientists May Be Closing in on the Higgs Boson Particle - on.mash.to/vXc62y
Europe’s Large Hadron Collider (LHC), which has been consistently operating since 2009 after a botched grand opening the previous year, is theoretically capable of seeing hints of the Higgs boson, and now the rumor among the physics community is that it’s done just that. A two-part lecture scheduled for Dec. 13 at the European Organization for Nuclear Research (CERN) has the tantalizing title, “Update on the Standard Model Higgs searches.”

ヒッグス粒子の発見かどうかは分からないけれど、ついこないだまでは、粒子があったとしても(有意に高い確度)、検出が難しいエネルギー領域にあるかもしれないという悲観的な予測が蔓延していただけに、蓋を開けてみると、NASAみたいに「観測できるかも」レベルの見通しで予算クレクレパフォーマンスの可能性も捨てきれない。

@drg1985 Even a non-rumored 3.5 sigma signal isn't enough for proof of anything. No point speculating this early. We're still a ways off.

ヒッグスボソン緊張~☆ っていうか3.5sigma signal云々って「噂」の域なのか。。粒子の存在が確定出来る可能性は高いが、実際に補足出来るかどうかは今後の課題って発表に落ち着きそうな予感はする。

□ Metadynamics in the conformational space nonlinearly dimensionally reduced by Isomap

分子モデル内における原子の集団運動:立体配座空間の自由エネルギー面メタ・ダイナミクスの非線形次元を、Isomapを用いて72次元から3次元まで削減する
Here we present a simulation with a bias potential acting in the directions of collective motions determined by a nonlinear dimensionality reduction method. Ad hoc generated conformations of trans,trans-1,2,4-trifluorocyclooctane were analyzed by Isomap method to map these 72-dimensional coordinates to three dimensions, as described by Brown and co-workers. Metadynamics employing the three-dimensional embeddings as collective variables was applied to explore all relevant conformations of the studied system and to calculate its conformational free energy surface.







□ Generating 3-D models of RNA from limited experimental data.

The nucleic acid simulation tool (NAST) has been written for this purpose and can be downloaded for free from https://simtk.org/home/nast. Read more about the validation of this tool in the article "Course-grained modeling of large RNA molecules with knowledge-based potentials and structural filters" in the Feb. 2009 issue of RNA (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2648710/?tool=pubmed).

水が液体で存在可能な惑星確認 気温22度、地球の2・4倍
米航空宇宙局(NASA)は5日、生命に欠かせない水が液体で存在し得る惑星を、ケプラー宇宙望遠鏡による観測で確認したと発表した
Kepler 22-b, which is about 2.4 times the size of Earth and lies in the so-called "Goldilocks zone", has a relatively comfortable surface temperature of about 22C (72F) and orbits a star not unlike Earth's sun.

But while astronomers believe that it "probably" also possesses water and land, earthlings secretly harbouring hopes that such a planet could potentially host new colonies from our own increasingly overpopulated home may be in for a disappointment.

About 600 light-years from Earth, Kepler 22-b is a considerable trek away while experts are not yet sure if it is made mostly of rock, gas or liquid

Dencity maps population density using circles of various size and hue. Larger, darker circles show areas with fewer people, while smaller, brighter circles highlight crowded cities. Representing denser areas with smaller circles results in additional geographic detail where there are more people, while sparsely populated areas are more vaguely defined.

There were a remarkable amount of talks on connecting SMW with the rest of the Semantic Web, through RDF, SPARQL etc. Cool, SMW is seemingly becoming a natural choice of platform for SemWeb publishing!

The proportion of bio-people were also a bit remarkable. Apart from SNPedia founder Mike Cariaso, there were a whole bunch of others, including Salvadore from the GeneWiki project, Toni .... (and me) .... I guess it reflects how good SMW handles the need to give structure to very heterogenous datasets, so typical for the Life Sciences.

NatureJapan: 遺伝子における予測可能性 nature.asia/tVXjbI
Predicting mutation outcome from early stochastic variation in genetic interaction partners
遺伝子決定論に限界があることは、臨床でも(一卵性双生児での遺伝学的病変の転帰が同一ではないことから)、また実験においても(同質の環境下であっても、変異によって同系動物間にさまざまな影響が生じることから)、ずっと以前から明らかだった。そうだとしても、個体の表現型は予測可能かもしれないと考えたB Lehnerたちは、発生中の動物で変異の帰結を直接予測する方法を考案した。

非侵襲的な、蛍光を用いる方法によって、線虫(Caenorhabditis elegans)の胚発生過程での遺伝子発現のゆらぎを監視し、各胚の分子ノイズとその胚に対応する成体の表現型を後ろ向きに比較したのである。そして、密接に関係する遺伝子間に生じる調節補償作用と、シャペロンなどの一般的な調節因子がかかわる調節補償作用が明らかになった。こうした補償の強さによって、動物ごとの成体表現型が予測される。

Two use cases, clinical document sections, and the 2010 i2b2/VA NLP Challenge (i.e., problems, tests, and treatments, with their assertions and relations), were used to create examples of such standoff annotation documents, and were successfully validated with the XML schemata provided with both standards. We developed a tool to automatically translate annotation documents from the 2010 i2b2/VA NLP Challenge format to GrAF, and automatically generated 50 annotation documents using this tool, all successfully validated.

RNA-SeQC: RNA-Seqデータの品質管理メトリクスを計算するJavaプログラム
RNA-SeQC is a java program which computes a series of quality control metrics for RNA-seq data. The input can be one or more BAM files. The output consists of HTML reports and tab delimited files of metrics data. This program can be valuable for comparing sequencing quality across different samples or experiments to evaluate different experimental parameters. It can also be run on individual samples as a means of quality control before continuing with downstream analysis.

RNA-SeQC is built on the GATK as well as the Picard API.
