The sinR ortholog PGN_0088 encodes a transcriptional regulator that inhibits polysaccharide synthesis in Porphyromonas gingivalis ATCC 33277 biofilms. [PDF]

PLoS ONE, 2013
Biofilm-forming cells are distinct from well characterized planktonic cells and aggregate in the extracellular matrix, the so-called extracellular polymeric substances (EPS).

Blind SINR Estimation Based on Graph Sparsity

, 2020
In this paper, a novel blind signal-to-noise-plus-interference ratio (SINR) estimator is proposed based on graph sparsity. The graph representation, which can serve as a new promising alternative to time-, frequency-, and transform-domain waveforms, is ...

SinR’ interacts with SinR.

, 2018
(A)In vitro, protein-protein interactions indicate that SinR’ binds tightly to SinR. GST-tagged SinR’ protein was incubated with SinR-6His proteins and purified using Ni++ agarose affinity columns.

Min-SINR Maximization for mmWave Massive MISO-NOMA System With Randomly Directional Beamforming

IEEE Access, 2020
Based on the high-direction characteristic of millimeter wave (mmWave) transmission, randomly directional beamforming (RDB) can be used for the mmWave massive multiple-input single-output (MISO) non-orthogonal multiple access (NOMA) system to reduce the ...

Decoupled Access in HetNets With Backhaul Constrained Small Base Stations

IEEE Access, 2018
This paper investigates the uplink (UL) and downlink decoupled access in heterogeneous networks with backhaul constraints. A capacity-based user association policy is proposed for users with decoupled access, where small base stations (SBSs) connect to ...
