Central dogma is the most fundamental hypothesis in field of molecular biology and explains genetic information flow from DNA to protein. Beyond residue-by-residue transmission sequential information, chemical modifications DNA, RNA, protein are also relayed course gene expression. Here, this work presents recent evidence supporting bidirectional interplay between chromatin RNA modifications. F...

Morphological studies have shown that excitatory synapses from the cortex constitute the major source of synapses in the thalamus. However, the effect of these corticothalamic synapses on the function of the thalamus is not well understood because thalamic neurones have complex intrinsic firing properties and interact through multiple types of synaptic receptors. Here we investigate these compl...

Relay-enhanced networks are expected to fulfil the demanding coverage and capacity requirements in a cost-efficient way. Type 1 inband relaying has been standardised as an integral part of the Third Generation Partnership Project (3GPP) LongTerm Evolution Release 10 and beyond (LTE-Advanced). This type of relay nodes (RNs) supports a relaying mode where the RN to donor evolved node B (donor eNB...

The paper studies the capacity of the OFDM and the OFDMA relay networks. Two relay schemes, amplify-and-forward (AF) relay and decode-and-forward (DF) relay are analyzed and compared for both OFDM and OFDMA relay networks. A relay node selection algorithm is proposed for OFDMA relay network. Numerical results show that under small relay power transmission, AF outperforms DF while the opposite i...

to evaluate the yield components, yield and land equivalent ratio affected by relay intercropping of sunflower (helianthus annuus l.) with faba bean (vicia faba l.), a field experiment was arranged based on a randomized complete block design with three replications at the agricultural research station payamenoor university of nagadeh, iran during growing reason of 2012-2013. the treatments incl...

results linear mixed model analyses showed that athletes slept on average 43 minutes longer when they slept during usual (night) times than during abnormal (day) times. in general, sleep duration decreased during the race with on average 18 minutes per period. conclusions this pilot study shows that, even under extreme violation of sleep hygiene rules, there still is an apparent effect of circa...

Co-operation and network coding are two such powerful techniques that heightened the proficiency of wireless Networks. This paper mainly focuses on Physical-layer Network Coding (PNC) and Analog Network Coding (ANC), as they are the most studied variants of network coding in literature and represent radically different strategies between themselves, thus shedding light into which problems may h...

Cooperative relay systems have become an active area of research during recent years since they help cellular networks to enhance data rate and coverage. In this paper we develop a method to jointly optimize precoding matrices for amplify-and-forward relay station and base station. Our objective is to increase max–min SINR fairness within co-channel users in a cell. The main achievement of this...

This paper considers coordinated user scheduling in a multi-user two-hop multiinput multi-output relay system with limited feedback. The proposed scheme utilizes a quantized transmit correlation and channel quality information, enabling to achieve both interference mitigation and multi-user diversity (MUD) gain. To this end, we first investigate the effect of quantization error on the statistic...
