Kleene is a high-level programming language, based on the OpenFst library, for constructing and manipulating finite-state acceptors and transducers. Users can program using regular expressions, alternation-rule syntax and right-linear phrase-structure grammars; and Kleene provides variables, lists, functions and familiar program-control syntax. Kleene has been approved by SAP AG for release as ...

Using thermal evaporation, we fabricated five uniform and regular arrays of Ag nanostructures with different shapes that were based on an anodized aluminum oxide template and analyzed their optical properties. Round-top-shaped structures are obtained readily, whereas to obtain needle-on-round-top-shaped and needle-shaped structures, control of the directionality of evaporation, pore size, lengt...

introduction: viral hepatitis is one of the causes of premature death in world peoples, according to who reports, five percentage of people are carrier, lethal from this disease is 1%, therefore about 1-1.5 million people each year die from complications of this disease. this disease varies from an acute to chronic illness. the aim of this study was to determine the level of anti-hbs ag (hepati...

Abstract In a solution of HF with HNO 3 as an oxidizing agent, silver-catalyzed etching p-type silicon is made easier. Before immersing in the etchant solution, silver (Ag) was electroless deposited on p-Si (100) surface. By stain HF/HNO , porous layer (PSL) also produced p-Si. Electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), atomi...

the rapid advancement of nanotechnology enables us to use nanoscale particles. this material in terms of physical, chemical and biological characteristics are unique compared to larger particles. increased cell division, apoptosis, oxidative stress has been associated with toxic effects of nano-silver. the aim of this study was to evaluate histipotological changes and enzyme activity in nanopar...

infection with hepatitis c virus (hcv) is a worldwide problem. among hcv proteins, core antigen (ag), besides its importance for diagnostic application is a prime candidate for component of a vaccine. herein, we report results of studies on production of the hydrophilic domain of core ag (2-122) in native conformation by an arabinose induction system in e.coli and the primary characterization o...
