This paper considers the possibility of spontaneous transition of aracemic mixture (composed of equal amounts of two enantiomeric species, say L and D) into a monochiral state (in which only one enantiomer, say L, is present). Transitions of this kind have been recently experimentally observed. A plausible approach to this phenomenon is a model put forward by Frank, based on simple laws of ...

[Background of this unusual double interview: the Free Software Magazine (http:// www.freesoftwaremagazine.com) and the TEX Users Group (TUG) both like to publish interviews. By chance, Gianluca Pignalberi of FSM and Dave Walden of TUG both approached Frank Mittelbach about interviewing him around the same time. Rather than doing two separate interviews, Mittelbach, Pignalberi, and Walden decid...

Large-scale, algorithmic access to LOD Cloud data has been hampered by the absence of queryable endpoints for many datasets, a plethora of serialization formats, and an abundance of idiosyncrasies such as syntax errors. As of late, very large-scale — hundreds of thousands of document, tens of billions of triples — access to RDF data has become possible thanks to the LOD Laundromat Web Service. ...

background: various techniques are used in diagnosing cardiac diseases. the electrocardiogram is one of these tools in common use. in this study vectorcardiogram ) vcg ( signals are used as a tool for detection of cardiac ischemia. methods: vcg signals used in this study were obtained form 60 patients suspected to have ischemia disease and 10 normal candidates. verification of the ischemia had ...
