We analyze the impact of size-based scheduling on the flow level performance of elastic traffic in wireless downlink data channels. The impact is assessed by comparing the flow level delay of the simple RR scheduler to two optimized non-anticipating schedulers (FB and FB◦) and SRPT. The optimized distance-aware scheduler FB◦ is derived by applying the Gittins index approach. Our results show th...
We compare the overall mean response time (a.k.a. sojourn time) of the processor sharing (PS) and feedback (FB) queues under an M/GI/1 system. We show that FB outperforms PS under service distributions having decreasing failure rates; whereas PS outperforms FB under service distributions having increasing failure rates. c © 2003 Elsevier B.V.

Interleukin-2 (IL2) is a cytokine that can stimulate cytotoxic immune cells to attack infected and malignant cells. Unfortunately, IL2 can also cause serious immune-related toxicity. Recently, a mutant of IL2 (IL2v) with abolished CD25 binding, increased plasma half-life and less toxicity was engineered. Unlike wild-type IL2 (wt-IL2), mutant IL2v does not bind to the α-subunit (CD25) of the hig...
BACKGROUND Supplemental oxygen (O(2)) is mandatory during flexible bronchoscopy (FB) in infants, but there are limited studies that deal with the efficacy of different O(2) delivery methods. This study aims to compare the oxyhemoglobin saturation in infants during FB among three different O(2) delivery methods, as measured by pulse oximeter (SpO(2)). METHODS A prospective study enrolled infan...
Effects of partial substitution of barley grain and soybean meal with fleabane (FB) Conyza bonariensis on growth performances and body compositions of 24 male local Awassi lambs were studied. All lambs were male with an average BW of 20.3 kg (s.d. = 2.0 kg) at the beginning of the experiment. Animals were randomly divided into four groups of six lambs each. Lambs in each group received individu...
The pathophysiology of myocardial injury that results from cardiac ischemia and reperfusion (I/R) is incompletely understood. Experimental evidence from murine models indicates that innate immune mechanisms including complement activation via the classical and lectin pathways are crucial. Whether factor B (fB), a component of the alternative complement pathway required for amplification of comp...
Fish bone foreign body (FFB) is the most frequent food-associated foreign body (FB) in adults, especially in Asia, versus meat in Western countries. The esophageal sphincter is the most common lodging site. Esophageal FB disease tends to occur more frequently in men than in women. The first diagnostic method is laryngoscopic examination. Because simple radiography of the neck has low sensitivit...
