background and aims: stellate ganglion is a sympathic ganglion in the neck area which by effective blocking a lot of chronic pain syndromes at upper limbs, head, neck and chest can be treated. in this study, results of ultrasound-guided stellate ganglion block in 44 patients have been reviewed. methods and material: in this descriptive study, 44 patients candidate for stellate ganglion block du...

Effective approximations are developed for the blocking probability in a general stationary loss model, where key independence and exponential-distribution assumptions are relaxed, giving special attention to dependence among successive service times, not studied before. The new approximations exploit heavy-traffic limits for the steady-state number of busy servers in the associated infinite-se...

Minimum-process coordinated checkpointing is a suitable approach to introduce fault tolerance in mobile distributed systems transparently. It may require blocking of processes, extra synchronization messages or taking some useless checkpoints. Allprocess checkpointing may lead to exceedingly high checkpointing overhead. To optimize both matrices, the checkpointing overhead and the loss of compu...

Concepts of non-volatile memory to replace conventional flash memory have suffered from low material reliability and high off-state current, and the use of a thick, rigid blocking oxide layer in flash memory further restricts vertical scale-up. Here, we report a two-terminal floating gate memory, tunnelling random access memory fabricated by a monolayer MoS2/h-BN/monolayer graphene vertical sta...

Rhabdomyosarcoma (RMS) is a soft tissue sarcoma usually diagnosed in children. In advanced and metastatic stages the prognosis is often poor. RMS cell lines were used for evaluation of the role of MET receptor inhibition on chemotaxis and invasion. In vivo studies were performed using NOD-SCID xenograft model. This study shows that blocking of MET expression has strong influence on metastatic b...

1200 V/ 3 mm active-area SiC “Super” Junction Transistors (SJTs) display current gains as high as 88 and majority carrier operation up to 250 °C. The SJT operation shifts from purely unipolar to bipolar-mode at temperatures ≥ 300 °C. The leakage currents at a blocking voltage of 1200 V remain below 100 μA, even at 325 °C. Temperature-independent turn-on and turn-off times < 15 ns are measured u...

Given a nite time interval [0; T ], a xed number of customersN , a stochastic service system with C servers, and an initial occupancy distribution (0), we show how to calculate a schedule for the customer arrival times to minimize average blocking. We have in mind a facility user who infrequently receives a burst of N items to submit where N is a random variable. If such a \bursty" user can tol...

An m × n row-column factorial design is an arrangement of the elements a into rectangular array. Such array used in experimental design, where rows and columns can act as blocking factors. Formally, for any integer q, let [ q ] = { 0 , 1 … − } . The k (full) with replication α multiset consisting occurrences each element ; we denote this by A regular (which say type I ( ) such that row (column)...

Ilidar, a new adrenergic blocking drug, has been administered to 116 patients; follow-up was adequate on 86. The drug was highly effective in patients with predominantly vasospastic disorders and in patients with postphlebetic syndrome, and moderately effective in patients with thromboangiitis and arteriosclerosis. Most patients could tolerate 50 to 75 mg. three to four times a day. Side effect...
