A highly sensitive and continuous protein tyrosine phosphatase (PTPase) assay using 3,6-fluorescein diphosphate (FDP) is described. Leukocyte phosphatase CD45 (leukocyte common antigen), protein tyrosine phosphatase-1B, and leukocyte common antigen-related protein LAR preferentially hydrolyze FDP to fluorescein monophosphate (FMP) with V(max) and K(m)(More)
In this paper, we present a high performance, low cost and low power hardware architecture for real-time implementation of forward transform and quantization and inverse transform and quantization algorithms used in H.264 / MPEG4 Part 10 video coding standard. The proposed hardware implementation is based on a reconfigurable datapath with only one(More)
A 31-year old male presented with bone pain, polyuria and a palpable nodule in the neck. Radiological examination showed generalised osteopenia, subperiosteal erosion and presence of bilateral renal stones. The essential chemical pathological changes were increased plasma calcium, mid-molecule immuno-reactive parathyroid hormone (iPTH), human chorionic(More)
Cholecystectomy represents the second most common surgery during pregnancy. Both general and regional anesthetic techniques have been successfully used for cholecystectomy in pregnant patients. Authors present here a case of a pregnant patient carrying twin gestation who underwent cholecystectomy, which is not frequently encountered by the(More)
Mobile Internet Protocol(MIP), an industry standard for handling mobility, suffers from high handover latency and packet loss, in addition to change in network infrastructure. To overcome these problems, we proposed a new approach called Seamless IP diversity based Generalized Mobility Architecture (SIGMA). Although SIGMA achieved a low latency handoff, use(More)
Model In the cache-oblivious setting the computational model is a machine with two levels of memory: a cache of limited capacity and a secondary memory of infinite capacity. The capacity of the cache is assumed to be M elements and data is moved between the two levels of memory in blocks of B consecutive elements. Computations can only be performed on(More)

In the recent technology advances, an increasing number of users are accessing various information systems via wireless communication. The majority users in a mobile environment are moving and accessing wireless services for the activities they are currently unavailable inside. We propose the idea of complex activity for characterizing the continuously(More)
