Sentence examples for upstream us from inspiring English sources

Each two 16-QAM MIMO signals that have the same carrier frequency in the downstream (DS) transmission are optically combined using polarization-division-multiplexing (PDM), where each two upstream (US) MIMO signals are time division multiplexed.

In this paper, a sleep-aware dynamic bandwidth allocation (SDBA) algorithm and the supporting protocol are proposed for maximizing energy efficiency while satisfying the end-user QoS constraints on downstream (DS) and upstream (US) transmissions in 10G-EPONs.

qChIP experiments were carried out using chromatin prepared from untreated, UV treated cells in the presence or absence of caffeine, and the relative occupancy of Pol II was determined by qChIP analysis on upstream (US), transcription start site (TSS, proximal), coding region (CD) and 3'-end region (distal) (Fig. 4).

The nucleosome-free region (NFR) on all but three yeast tDNAs is found bordered by an upstream (US) nucleosome strongly positioned at −140 bp position and a downstream (DS) nucleosome at variable positions with respect to the gene terminator.

It is fully evident from this data that a strongly positioned upstream (US) nucleosome, the NFR on tDNAs and nucleosome downstream of the gene are not sequence-directed, rather the result of a fine balance between specific activities of the chromatin remodelers RSC and ISWI.

A stronger upstream (US) nucleosome positioning, persistence of NFR under repression on most of the genes, sequence-independence of NFR and requirement of remodeler activities to maintain the chromatin structure in active state, are some of the observations which suggest tDNA NFRs are different from the 5' NFR on pol II-transcribed genes.

Most tDNAs (82%) show a strongly positioned upstream (−1, US) nucleosome, centered at −140 bp position with respect to TSS while position of the downstream (+1, DS) nucleosome varies across the genes.

The 5' upstream sequence (5' US) of c- fos contains a promoter controlled by cAMP or Ca2+ signaling through a cAMP response element (CRE), mitogen-activated protein kinases that respond to growth hormones, or a stress-signaling pathway dependent on STATs (signal transducers and activators of transcription) [ 31].

US 13 turns west into wooded areas before crossing the Pocomoke River upstream of US 13 Bus.. Upon crossing the Pocomoke River, US 13 heads into Somerset County and intersects the northern terminus of US 13 Bus.

Matt Prindiville is the associate director for UPSTREAM, a US-based environmental policy organization dedicated to addressing the root causes of waste.

The claims submitted by the human rights groups describe Prism and Upstream as US-run mass data collection programmes.
