Background: Since Tehran University of Medical Sciences (TUMS) has the oldest and highest number of research centers among all Iranian medical universities, this study was conducted to evaluate scientific output of research centers affiliated to Tehran University of Medical Sciences (TUMS) using scientometric indices and the affecting factors. Moreover, a number of scientometric indicators we...

One important factor which makes the rehabilitation of a leprosy patient difficult is his common development of emotional aberrations. In the minds of the people, leprosy is so much associated with sin, punishment, physical disfigurement and social isolation that it is a very traumatic experience for the patient to accept the diagnosis . It is no wonder that leprosy patients often develop compl...

The tum gene of coliphage 186, encoded on a LexA controlled operon, is essential for UV induction of a 186 prophage. Primer extension analysis is used to confirm that Tum is the sole phage function required for prophage induction and that it acts against the maintenance repressor, CI, to relieve repression of the lytic promoters, pR and pB, and thereby bring about lytic development. In vitro ex...

In Carrer Rossell6, a pedestrian street of a neighbourhood in Matar6, Catalonia, a couple of large seats half-heartedly invited people to rest, chat, or daydream. It was one of the few permanent installations inviting social gatherings on Carrer Rossell6. Most of the time when I passed by, a couple of people would be sitting there or a smaller group would stand around and chat. On a visit in 20...

An efficient matrix solver is critical to the analytical placement. As the size of the matrix becomes huge, the multilevel methods tum out to be more efficient and more scalable. Algebraic Multigrid (AMG) is a multilevel technique to speedup the iterative matrix solver [lo]. We apply the algebraic multigrid method to solve the linear equations that arise from the analytical placement. A layout ...

Secret sharing is that a dealer distributes a piece of information (called a share) about a secret to each participant such that authorized subsets of participants can reconstruct the secret but unauthorized subsets of participants cannot determine the secret. If any unauthorized subset of participants can not obtain any more information regarding the secret, then the scheme is called perfect. ...
