To enhance the throughput of a slotted random access protocol in a radio communication system, we describe the use of a scheme in which multiple power levels are used at the transmitters. We first consider a situation in which n transmitters are simultaneously trying to send a packet to a central receiving station using a time-slotted access protocol, like slotted ALOHA. Each of these transmitt...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
A novel high-throughput screen reveals yeast genes that increase secretion of heterologous proteins.
The yeast Saccharomyces cerevisiae is an attractive host for the production of heterologous proteins. However, low-yield production of many proteins (from micrograms to milligrams/liter) leaves considerable room for optimization. By engineering the yeast cell via traceable genome-wide libraries, genes that can enhance protein expression level because of their roles in protein transcription, tra...
Ad hoc networks employing adaptive-transmission protocols can alter transmission parameters over a particular link to suit the perceived channel environment. Such capabilities can lead to significant performance improvements over statically configured protocols. Ad hoc networks rely on channel-access mechanisms to govern temporal use of the transmission medium amongst the individual network nod...
Tetrahydrobiopterin (BH(4)) is an essential cofactor for the nitric oxide (NO) synthases and the aromatic amino acid hydroxylases. Insufficient BH(4) has been implicated in various cardiovascular and neurological disorders. GTP cyclohydrolase 1 (GTPCH-1) is the rate-limiting enzyme for de novo biosynthesis of BH(4). The authors have recently shown that the interaction of GTPCH-1 with GTP cycloh...
The use of effective software in Computer Aided Process Planning (CAPP) can contribute significantly towards cost reduction and improvement in production rate. The most important elements of CAPP are the ability to effectively evaluate various machining process sequences and the utilization of the most appropriate machining parameters including machines, tools and tool grades and tool angles, c...
This paper proposes a two-dimensional spreading method in UMTS Long Term Evolution (LTE). Such method brings additional time-frequency diversity which is beneficial in terms of the ability to decode transmitted dat at the receiver side under multipath fading. Additional diversity is caused by the fact that chips of transmitted signals are spread with a Walsh-Hadamard spreading sequence over sev...
Somatic rearrangements, which are commonly found in human cancer genomes, contribute to the progression and maintenance of cancers. Conventionally, the verification of somatic rearrangements comprises many manual steps and Sanger sequencing. This is labor intensive when verifying a large number of rearrangements in a large cohort. To increase the verification throughput, we devised a high-throu...
Rate allocation has become a demanding task in data networks as diversity in users and traffics proliferate. Most commonly used algorithm in end hosts is TCP. This is a loss based scheme therefore it exhibits oscillatory behavior which reduces network performance. Moreover, since the price for all sessions is based on the aggregate throughput, losses that are caused by TCP affect other sessions...
