background: the purpose of this study was to evaluate the results of stereotactic breast core needle biopsy in a tertiary breast center of tehran university of medical sciences. methods: patients who were candidates for mammography-guided stereotactic breast core biopsy from march 2011 to december 2013 were included in this study. stereotactic biopsy was performed by a dedicated prone hologic m...

Mobile hotspots, i.e. Internet access services in moving networks (e.g. vehicular area networks (VAN) and personal area networks (PAN)) bring about new challenging issues. Even if the network mobility (NEMO) basic support protocol has been standardized as a mobility solution by the Internet Engineering Task Force (IETF), to the best of our knowledge, no studies have been conducted in the area o...

introduction: hepatitis c virus (hcv) infection is a major public health problem which influences about 170 million people worldwide. different types of vaccines have been designed using hcv structural proteins to control the viral infection. the core nucleocapsid protein is one of the most conserved proteins and a desirable target for hcv vaccines, especially the protein-based vaccines. in cur...

Intellectual property rights (IPRs) have attracted increasing attention both in academic circles as well as in public policy debates over the past decades. This has gone hand-in-hand with their increasing use, particularly (but not only) patents, reforms in the national and international legal frameworks that have resulted in the strengthening of IPRs and the fast growth of sectors in which kno...

Taking advantage of multi-thread technology provided by multi-core in single processor, this paper describes multi-thread implementation on fingerprint direct-access strategy using local-startopology-based discriminator features. Multi-thread was applied for data partitioning on hashing addlookup process, and for work partitioning on similarity score computation. Efficiency of the implementatio...

stewardship is not a new concept for public policy, but has not been used to its optimum by the health policy-makers. although it is being practiced in most successful models of health system, but the onus to this function is still due till date. lately, few experts in world health organization (who) have realized its importance and have been raising the issue at different platforms to pursue t...

The proliferation of the internet as and instructional medium has given rise to the growth of numerous types of online training. Distance learning, e-learning or blended learning are phrases exchanged frequently, as students and corporate employees log on to instructional sites at college, at the library or between staff meetings. Although thousands of small businesses are established each year...

We discuss flux pinning and nanostructural analyzes of two intermetallic superconductors that exhibit substantial deviations from the usual flux-shear behavior. Kramer plots for a MgB 2 thin film, which contained a substantial fraction of MgO nanoprecipitates, show an additional component that is attributed to core pinning by the precipitates. Also, polycrystalline MgCNi 3 displays a crossover ...
