ناحیه ظرفیت برای انتقال اطلاعات کلاسیک بر روی کانال های کوانتومی multiple acsses و همچنین انتقال اطلاعات کلاسیکی بصورت امن بر روی کانال های کوانتومی نقطه به نقطه، قبلاً محاسبه گردیده است. در این کار با استفاده از اثبات قضیه ظرفیت اطلاعات کلاسیک و نیز استفاده از قضیه اپراتورهای chernoff bound، ناحیه ظرفیت جدیدی جهت انتقال امن اطلاعات کلاسیک برروی کانال های کوانتومی multiple acsses با دو فرستنده و...
in this paper, a block-based method in wavelet domain for sar image coding is presented based on the ezbc algorithm. to better preserve edges and textural structure in sar images, instead of using traditional dyadic wavelet transform, a packet wavelet is employed. to improve the efficiency of the ezbc algorithm for sar image coding, a modified version of this algorithm, is proposed. this modifi...
there are dierent ways to code the geodesic flows on surfaces with negative curvature. such code spaces give a useful tool to verify the dynamical properties of geodesic flows. here we consider special subspaces of geodesic flows on hecke surface whose arithmetic codings varies on a set with in nite alphabet. then we will compare the topological complexity of them by computing their topologica...
One of the most efficient mechanisms by which plants protect themselves from invading virusesis the specific RNA-dependent silencing pathway termed post-transcriptional gene silencing(PTGS). In this mechanism, resistance to a virus is engineered through the expression of asegment of the virus genomein transgenic plants. Potato VirusY (PVY) is one of the mostdamaging viruses of potato, infecting...

Introduction: Every health organization life depends on its correct coding system. One of the best tools in collecting correct and valid data is to make a clinical coding and procedures. Clinical Coding policy and procedures, in face of personals changes causes stability, and continues the clinical coding and provide a frame for decision making and doing duties . Methods: This research was carr...
Abstract Background &Aims : Use of coded data for quality management, health care financing and health care policy requires a simplification of valid coding . Most programs aim to improve the quality of coded data by improving the accuracy of codes assigned by the coding staff. This study was done for determine of coders view about effective factors on coding and quality improvement me...
We study the capacity of point-to-point erasure networks under a restricted form of network coding to which we refer as spatial network coding. In this form of coding, the nodes can not perform coding on successive packets which are received from one incoming link. The coding at a node is restricted to the packets received at the same time slot from different incoming links...
medical information plays a pivotal role in collecting health information which can be used to determine the main health problems at national and international levels and to change main health policies. patient management is impossible without having accurate information regarding prevention, treatment and recovery of diseases. thus, in this issue of international electronic journal of medicine...
