Joint source-channel coding has been introduced recently as an element of QoS support for IP-based wired and wireless multimedia. Indeed, QoS provisioning in a global mobility context with highly varying channel characteristics is all the most challenging and requires a loosening of the layer and source-channel separation principle. Overcomplete frame expansions have been introduced as joint so...

We report a 13 year old boy with fragile X syndrome resulting from a de novo deletion of the FMR1 and FMR2 genes extending from (and including) DXS7536 proximally to FMR2 distally. The patient has severe developmental delay, epilepsy, and behavioural difficulties, including autistic features. He has epicanthic folds, in addition to facial features typical of fragile X syndrome, and marked joint...

This paper considers a retrial queueing model for a base station in cellular networks where fresh calls and handover calls are available. Fresh calls are initiated from the cell of the base station. On the other hand, a handover call has been connecting to a base station and moves to another one. In order to keep the continuation of the communication, it is desired that an available channel in ...

Serial computer assisted quantitative sacroiliac scintiscanning (SI joint/sacrum ratios) 3 hours after low dosage (5 mCi) 99mTc methylene diphosphonate has been used as an objective index of sacroiliitis in a single blind 14-day cross-over comparison of azapropazone 600 mg b.d. and naproxen 500 mg b.d. in 18 patients with active sacroiliitis. Clinical assessments included visual analogue scales...

Dendritic cell immunoreceptor (Clec4a2, DCIR) is one of C-type lectin receptors (CLRs), which is predominantly expressed in dendritic cells (DCs) [1]. DCIR contains a carbohydrate recognition domain in the extracellular part and an immunoreceptor tyrosine-based inhibitory motif (ITIM) in the cytoplasmic region which can negatively regulate immune signaling by recruiting phosphatases, SHP-1 and ...

With the rapid development of microelectronic interconnection technology, reliability requirements electronic products are becoming higher and higher. Among them, temperature has greatest impact on devices. Due to different coefficients thermal expansion (CTE) between many materials a chip, inside solder joint is subjected cyclic action. Under effect temperature, joints subject internal fractur...

the arthroscopic study of knee joint is of outstanding interest in assessment of knee complaints. the present article describes the results of arthroscopic examination of 100 patients (mean age 29.4 years 82% male) evaluated from 1996 to 1997 in imam khomeini hospital of tehran. sport injury was the most prevalent cause of referral (40%). the 2 most frequent complaints were knee pain (94%) and ...
