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...

Out–of–core rendering techniques are necessary for viewing large volume disk–resident data sets produced by many scientific applications or high resolution imaging systems. Traditional visualizers can provide real–time performance but require all of the data to be viewed to be in the RAM. We describe a multithreaded implementation of an out–of–core isosurface renderer that does not impose such ...

For the first time we present the synthesis of CeO(2)/Si(O)C core-shell particles prepared by the miniemulsion technique. The Si(O)C core was obtained by means of a polycarbosilane precursor (SMP10), which was subsequently functionalized with ceria and pyrolyzed to the ceramic. The size of these particles could easily be adjusted by varying the surfactants and the surfactant concentration, or b...

Schedulability analysis has been widely studied to provide offline timing guarantees for a set of real-time tasks. The so-called limited carry-in technique, which can be orthogonally incorporated into many different multi-core schedulability analysis methods, was originally introduced for Earliest Deadline First (EDF) scheduling to derive a tighter bound on the amount of interference of carry-i...

The Contractor Renormalization group (CORE) method, a new approach to solving Hamiltonian lattice systems, is introduced. The method combines contraction and variational techniques with the real-space renormalization group approach. It applies to lattice systems of infinite extent and is ideal for studying phase structure and critical phenomena. The CORE approximation is systematically improvab...

A technique for performing core biopsies of indeterminate masses of the extracranial head and neck is described. Four patients with suspicious masses of the extracranial head and neck underwent coaxial core biopsies through an 18-gauge Hawkins-Akins blunt tip needle. Three of the four patients had diagnostically adequate samples. There were no neurologic or vascular complications.

among different discretization approaches, finite difference method (fdm) is widely used for acoustic and elastic full-wave form modeling. an inevitable deficit of the technique, however, is its sever requirement to computational resources. a promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

the aim of the current study was to design a porous osmotic pump–based drug delivery system for controlling the release of buspirone from the delivery system. the osmotic pump was successfully developed using symmetric membrane coating. the core of the tablets was prepared by direct compression technique and coated using dip-coating technique. drug release from the osmotic system was studied us...
