Ad Hoc Networks are gaining popularity as a result of advances in smaller, more versatile and powerful mobile computing devices. The distinguishing feature of these networks is the universal mobility o f a l l hosts. This requires re-engineering of basic network services including reliable multicast communication. This paper considers the special case of(More)
BACKGROUND The objective of this study is to provide a retrospective analysis using an NIS database to examine national trends in outcomes for CSM from 1993 to 2002. METHODS Data for CSM admissions (n = 138792) were extracted from the 1993 to 2002 NIS database to determine overall outcomes, as well as for those patients with CSM who underwent spinal(More)
In cache-coherent non-untform memory access (CC-NUMA) multiprocessors, the amount of memory consumed by the directories grows with the number of memory blocks and the number of processors. In this paper, we propose to eliminate the cost of directories by storing directory entries in the same memory usedfor the data that we keep coherent. A memory block(More)
OBJECT Previous investigations of health outcome after spinal surgery for tethered cord syndrome (TCS) have been single-institution studies. The aim of this study was to report inpatient complications and outcomes on a nationwide level. METHODS The Nationwide Inpatient Sample (NIS) was used to identify patients who underwent spinal surgery for TCS in the(More)
Sclerosing lipogranuloma (SLG) of the male external genitalia is a rare benign condition presenting as subcutaneous masses. The underlying pathological process is a granulomatous reaction of fatty tissue in this area. The cause of this is unclear but hypothesis stems around the pathogenesis of exogenous lipid degeneration from injection of foreign bodies(More)

Urinary bladder catheter encrustations are known complications of long-term urinary catheterisation, which is commonly seen in clinical practice. These encrustations can impede deflation of the balloon and therefore cause problems in the removal of the catheter. The options in managing an encrusted and incarcerated urinary bladder catheter include(More)
