To combat the state-space explosion problem in model checking larger systems, abstraction techniques can be employed. Here, methods that operate on the system specification before constructing its state space are preferable to those that try to minimize the resulting transition system as they generally reduce peak memory requirements. We sketch a slicing algorithm for system specifications writ...

We characterize normalization by evaluation as the composition of a self-interpreter with a self-reducer using a special representation scheme, in the sense of Mogensen (1992). We do so by deriving in a systematic way an untyped normalization by evaluation algorithm from a standard interpreter for the λ-calculus. The derived algorithm is not novel and indeed other published algorithms may be ob...

In the present study an attempt was made to prepare alginate floating microparticles by ionotropic gelation method with calcium carbonate (CaCO3) 1% w/v in gelation medium used as gas-forming agent for oral delivery of Ofloxacin. Chitosan was used to enhance the drug encapsulation efficiency. Various physiochemical properties such as particle size, shape, in vitro buoyancy and drug release was ...

Receivers covering the VHF/UHF communications bands are the important parts of the EW/ESM systems. Currently used frequency agile signals using frequency hopping and burst transmission technique rise eminent requirements for scanning and search receivers. The fast scanning speed can be achieved with parallel signal processing based the spectrum estimation of a wide bandwidth of incoming signal....

I filaments (IF) represent one of the three major cytoskeletal systems found in animal cells. Their somewhat uninspired name was originally derived from their 10-nm diameter, which lies between that of smaller actincontaining microfilaments and larger microtubules. This name, however, belies their importance as critical players in the organization of cells and tissues of vertebrate systems. As ...

Elevated endothelin (ET)-1 has been implicated in cerebrovascular complications following brain trauma characterized by dysregulation of endothelial nitric oxide synthase (eNOS), protein kinase C (PKC), and cerebral function. Recently, vascular expression of PPAR has been observed and suggested to improve vascular dysfunction. We speculate that activation of PPAR in cerebral microvessels can im...

The LTSmin toolset provides multiple generation and onthe-fly analysis algorithms for large graphs (state spaces), typically generated from concise behavioral specifications (models) of systems. LTSmin supports a variety of input languages, but its key feature is modularity: language frontends, optimization layers, and algorithmic backends are completely decoupled, without sacrificing performan...
