Orthogonal Frequency Division Multiplexing (OFDM) has become a popular modulation method in high speed wireless communications. By partitioning a wideband fading channel into flat narrowband channels, OFDM is able to mitigate the detrimental effects of multipath fading using a simple one-tap equalizer. There is a growing need to quickly transmit information(More)
It has been suggested that the middle repetitive class of sequences that make up a large proportion of the eukaryotic genome have been amplified and dispersed by DNA transposition. Transposition is a phenomenon first postulated by Barbara McClintock on the basis of her genetic analysis of mutants in Zea mays. Since then, DNA transposition has been studied(More)
Unlike many other vertebrates, a healthy mammalian retina does not grow throughout life and lacks a ciliary margin zone capable of actively generating new neurons. The isolation of stem-like cells from the ciliary epithelium has led to speculation that the mammalian retina and/or surrounding tissues may retain neurogenic potential capable of responding to(More)
Using the relative expression levels of two SNP alleles of a gene in the same sample is an effective approach for identifying cis-acting regulatory SNPs (rSNPs). In the current study, we established a process for systematic screening for cis-acting rSNPs using experimental detection of AI as an initial approach. We selected 160 expressed candidate genes(More)
—We discuss the idea of differential fairness in polling systems. One such example scenario is: primary customers demand certain Quality of Service (QoS) and the idea is to utilize the surplus server capacity to serve a secondary class of customers. We use achievable region approach for this. Towards this, we consider a two queue polling system and study(More)
— Many device to device communication networks can be modelled by multi-class tandem queues. In many applications, it is desired to have different quality of service for various classes. This can be achieved by implementing dynamic priority across classes. Performance analysis is an important aspect in such multi-class tandem queueing models for resource(More)
— Completeness of some scheduling policies with mean waiting time performance measure is used quiet extensively in literature for dynamic control of multi-class queues due to its wide range of applications in computers, communication networks and manufacturing systems. For a single class queue, we introduce the idea of 2-moment completeness of a(More)
— Conservation laws and the related achievable region for mean waiting times are important concepts in multi-class queues. The nice geometric polytope structure of this region driven by the conservation law is exploited extensively for dynamic control of multi-class queues. Such control problems have wide range of applications in computers, communication(More)
