The paper presents an architecture for fast mode decision algorithm in H.264/AVC for 4x4 intra-prediction. This algorithm is based on the inherent symmetry existing in the spatial prediction modes. This algorithm gives a faster way of calculating sum of absolute differences (SADs) for all modes of intra prediction. So, a significant computational savings can be achieved. Synthesis results confi...

multi drug resistance(mdr) is a major problem in the treatment of cancer and hemalological malignancies. this resistance is multi factorial and is the result of decreased intra cellular drug accumulation. this is partly due to the presence of a 170kd intra membranous protein termed p-glycoprotein(p-gp) that is an energy-dependent efflux pump which has increased expression on drug-resistance cel...

This paper analyses the impact of sanctions against Iran in addition to other country-specific determinants on intra-industry trade between Iran and Shanghai Cooperation Organization (SCO) countries over the period 1997-2013. By disentangling total intra-industry trade (IIT) into horizontal and vertical IIT and after investigating bilateral trade pattern between Iran and SCO countries, determin...

Background& Objective: Fine needle aspiration cytology (FNAC) is an easy, rapid, and less hazardous tool to diagnose the intra-abdominal lesions with various imaging modalities adding to its sensitivity and accuracy. However, sometimes it does not yield adequate information for precise diagnosis and the risk of false-negative and indeterminate diagnosi...

background: an intra-articular distal humerus mal:union: can be disabling. to improve function, reduce pain and/ or prevent further secondary osteoarthritis an intra-articular corrective osteotomy can be considered. herein we present the indications, practical guidelines for pre- operative planning and surgical technique. subsequently, we provide long-term results in a small series.   methods: ...

the genus trachylepis fitzinger, 1843 encompasses two-three species in iran: trachylepis vittata (olivier, 1804) distributed in western iran, west of the zagros mountains; t.septemtaeniata (reuss, 1834) in southern regions of the zagros mountains and t. aurata transcaucasica chernov, 1926 from northern to central parts of the zagros mountains. for study of geographic variation in the latter two...

human action recognition is an important problem in computer vision. one of the methods that are recently used is sparse coding. conventional sparse coding algorithms learn dictionaries and codes in an unsupervised manner and neglect class information that is available in the training set. but in this paper for solving this problem, we use a discriminative sparse code based on multi-manifolds. ...
