Interchromosomal communication coordinates intrinsically stochastic expression between alleles.
Sensory systems use stochastic mechanisms to diversify neuronal subtypes. In the Drosophila eye, stochastic expression of the PAS-bHLH transcription factor Spineless (Ss) determines a random binary subtype choice in R7 photoreceptors. Here, we show that a stochastic, cell-autonomous decision to express ss is made intrinsically by each ss locus. Stochastic on or off expression of each ss allele ...
متن کاملOn-Chip Stochastic Communication
As CMOS technology scales down into the deep-submicron (DSM) domain, the Systems-On-Chip (SoCs) are becoming increasingly complex and the costs of design and verification are rapidly increasing due to the inefficiency of traditional CAD tools. Relaxing the requirement of " 100% correctness " for devices and interconnects drastically reduces the costs of design but, at the same time, requires th...

15 صفحه اولexamining the relationship between fear of negative evaluation and communication strategies by iranian efl learners
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
Interchromosomal Huddle Kickstarts Antiviral Defense
Long-distance chromosomal interactions are emerging as a potential mechanism of gene expression control. In this issue, Apostolou and Thanos (2008) describe how viral infection elicits interchromosomal associations between the interferon-beta (IFN-beta) gene enhancer and DNA binding sites of the transcription factor NF-kappaB, resulting in the initiation of transcription and an antiviral response.
