Hemihepatectomy along with portal vein or hepatic artery replacement in dogs was well tolerated, but combined with replacement of both vessels it was lethal because of outflow block and shock. Total liver blood flow should be kept as high as possible during such procedures in man.

ii To Mom and Dad, for everything. iii ACKNOWLEDGEMENTS Many people have made significant impacts in my life throughout my graduate school career. While I would be wont for space to individually thank each of the people who have touched my life during this time, I would like to express my heartfelt thanks to the following people for their great love, support, encouragement, and belief in me thr...

Billions of dollars allegedly lost to piracy of multimedia have recently triggered the industry to rethink the way music and movies are distributed. As encryption is vulnerable to re-recording, currently all copyright protection mechanisms tend to rely on watermarking. A watermark is an imperceptive secret hidden into a host signal. In this paper, we analyze the security of multimedia copyright...

Caching techniques have been used to improve the performance gap of storage hierarchies in computing systems. In data intensive applications that access large data files over wide area network environment, such as a data grid, caching mechanism can significantly improve the data access performance under appropriate workloads. In a data grid, it is envisioned that local disk storage resources re...

We consider a cache operating under a demand-driven replacement policy when document requests are modeled according to the Independent Reference Model (IRM). We characterize the popularity pmf of the stream of misses from the cache, the so-called output of the cache, for a large class of cache replacement policies, including standard on-demand replacement algorithms such as the policy A0 and th...

As capacity demands vary among simultaneously executed threads in chip multiprocessors, dynamically managing cache resources according to the run-time demands is effective to improve L2 cache performance. Differed from existing dynamic cache management schemes based on LRU replacement policy, we propose an adaptive capacity sharing mechanism based on a global reuse replacement policy. This mech...

While the field of computer architecture is always looking for novel research directions to bring improved performance and efficiency, it is often simple improvements to more mature topics that have the most substantial impact. Cache replacement policy is one such research area, where innovations are highly sought after because of their direct improvement on performance. Furthermore, as chip-mu...

OBJECTIVE In this retrospective study, we evaluated the demographic characteristics of patients that underwent hip replacement surgery in our orthopedic clinic. Associated diseases, preoperative laboratory findings, intraoperative findings, and the effect of admission or refusal to the intensive care unit on postoperative mortality and morbidity were recorded. Furthermore, we tried to identify ...

Atrioventricular (AV) block and pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) are rare complications of infective endocarditis (IE). A 72-year-old man with severe aortic stenosis was hospitalized due to IE. After admission, intermittent AV block and P-MAIVF were noted. Interestingly, an accelerated junctional rhythm was observed during the process of AV block resolution. E...

in order to study yield and yield components of fennel (foeniculum vulgare mill) – fenugreek (trigonella foenum-graecum l.) in different patterns of intercropping and sole cropping, an experiment with use replacement and additive intercropping based on randomized complete block design with three replications was conducted at the research station of faculty of agriculture, zanjan university, ira...
