Lee-Suzuki similarity transformations and Krencigowa-Kuo folded diagrams are two common methods used to derive energy independent model space effective interactions for nuclear many-body systems. We demonstrate that these two methods are equivalent to a Renormalization Group (RG) analysis of a toy 2-body problem. This is accomplished by considering a schematic model that can be solved in closed...

PDBsum is a web-based database providing a largely pictorial summary of the key information on each macromolecular structure deposited at the Protein Data Bank (PDB). It includes images of the structure, annotated plots of each protein chain's secondary structure, detailed structural analyses generated by the PROMOTIF program, summary PROCHECK results and schematic diagrams of protein-ligand an...

In the framework of schematic hard spheres lattice models we discuss Edwards' Statistical Mechanics approach to granular media. As this approach appears to hold here to a very good approximation, by analytical calculations of Edwards' partition function at a mean field level we derive the system phase diagram and show that " jamming " corresponds to a phase transition from a " fluid " to a " gl...

Grammar checking is the task of detection and correction of grammatical errors in the text. English is the dominating language in the field of science and technology. Therefore, the non-native English speakers must be able to use correct English grammar while reading, writing or speaking. This generates the need of automatic grammar checking tools. So far many approaches have been proposed and ...

A novel system has been developed that can link the evidence shown on a roadway to vehicle performance using an electronic paintball marking system. The field of traffic crash reconstruction uses roadway evidence to infer the dynamics of a vehicle. However, no inexpensive technique exists to verify that the evidence left on the roadway corresponds to particular levels of force or acceleration. ...

Architectural design – the art and science of designing space, building and the built environment – is a creative and complex task. It involves considerations of form (shapes, structure and configurations) and function (purposes and utilities). Whether form precedes function or vice versa (Janson, 1982; Anderson, 1987), the training and education of architects posits that successful design shou...
