A variable bit rate source is modeled as a Markov modulated deterministic uid ow (MMDFF) process. Each state in the stationary discrete time Markov chain represents one of a nite number of deterministic messages of xed lengths and variable bit rates. At the user network interface this sequence is served at a constant bit rate with a bu er of xed length. The combined system forms a regenerative ...

Nörodejeneratif hastalıklara olan ilgi özellikle son birkaç yılda belirgin bir şekilde artma göstermektedir. Fakat bu artan özel ilgiye rağmen, Alzheimer hastalığı (AH), Parkinson hastalığı (PD), multiple skleroz (MS) ve amiyotrofik lateral skleroz (ALS) gibi norodejeneratif hastalıkların patolojik mekanizmaları kesin olarak aydınlatılamamıştır. Endojen reaktif aldehitlerin (malondialdehit [MDA...

We propose a new authentication scheme of binding update protocol, which its Correspondent Node (CN) issues a ticket to Mobile Node (MN) when MN first executes the Binding Update (BU). This ticket assist that it is able to do efficiently the BU whenever MN requires the BU for the future. The proposed protocol need not be repeated equal BU course whenever the MN moves to foreign link or network,...

A numerical study aimed at investigating the roles of both the stratification and topographic slope in generation of turbulent coherent structures in the lee of capes is presented. We consider a steady barotropic current impinging on an obstacle in a rotating and linearly stratified environment. The obstacle is a triangular prism and represents an idealized headland extending from the coast. Nu...

DESIGNS FOR AN MPEG VIDEO CODER Y S Saw J M Hannah P M Grant Electrical Engineering, University of Edinburgh, Scotland Abstract In MPEG video encoding, e cient bu ering and rate control is especially crucial for constant bit rate (CBR) applications such as non-ATM (Asynchronous Transfer Mode) channels and satellite communication channels. In a CBR environment, compressed video data, which is in...

Hwangryun-haedok-tang (HRT) is the common recipe in traditional Asian medicine, and microbial fermentation is used for the conventional methods for processing traditional medicine. We investigated the inhibitory effect of the n-butanol fraction of HRT (HRT-BU) and fHRT (fHRT-BU) on the RANKL-induced osteoclastogenesis in bone-marrow-derived macrophages. mRNA expression of osteoclastogenesis-rel...

Salmonella typhimurium tolerated the replacement of about 70 % of the thymine in the DNA by 5-bromouracil (BU). In phage PLT-22 transduction, the presence of BU in the donor DNA had no effect on the linkage relationship of two contransduced markers and did not conclusively alter the ratio of complete transductants to abortive transductants. The yield of transductants per plaque-forming unit was...

We conducted a prospective cohort study testing the noninferiority of survival of ablative intravenous busulfan (IV-BU) vs ablative total body irradiation (TBI)-based regimens in myeloid malignancies. A total of 1483 patients undergoing transplantation for myeloid malignancies (IV-BU, N = 1025; TBI, N = 458) were enrolled. Cohorts were similar with respect to age, gender, race, performance scor...

Özet. Yapılan araştırmalar, her yıl birçok yazılım projesinin öngörülen bütçe ve çalışma takvimini aştığını ya da başarısız olduğu için iptal edilerek kaynak israfına neden olduğunu göstermektedir. Bu probleme yönelik çalışma alanlarından birisi de yazılım mühendisliği eğitim alanıdır. Ancak, endüstrinin ihtiyaç duyduğu istenilen bilgi ve becerilere sahip nitelikteki yazılım mühendislerinin hal...

To the Editor: Buruli ulcer (BU), caused by Mycobacterium ulcerans, is one of 13 recently classifi ed neglected tropical diseases (1). Little is known about factors infl uencing its focal distribution. In Benin, altitude may play a role in such distribution of BU. Incidence, prevalence, and other health-related data are usually reported at national or district levels. These data convey the impo...
