Sm-like protein Rof inhibits transcription termination factor ρ by binding site obstruction and conformational insulation [PDF]

Nature Communications
Transcription termination factor ρ is a hexameric, RNA-dependent NTPase that can adopt active closed-ring and inactive open-ring conformations. The Sm-like protein Rof, a homolog of the RNA chaperone Hfq, inhibits ρ-dependent termination in vivo but ...

ROF model on the graph

, 2014
In this paper we consider an analogue of the well-known in image processing, Rudin-Osher-Fatemi (ROF) denoising model on a general finite directed and connected graph. We consider the space BV on the graph and show that the unit ball of its dual space can be described as the image of the unit ball of the space ℓinfinity on the graph by a divergence ...

Effective Conservation Decisions Require Models Designed for Purpose: A Case Study of Boreal Caribou in Ontario's Ring of Fire. [PDF]

Ecol Evol
Decision making in conservation science often relies on the best available information, but existing models are rarely reproducible, transferrable, or accessible. We sought to reproduce and evaluate the suitability of the two best available models for predicting impacts of proposed mining on boreal woodland caribou (Rangifer tarandus caribou) in ...

Parry–Romberg syndrome associated with en coup de sabre in a patient from South Sudan – a rare entity from East Africa: a case report

Journal of Medical Case Reports, 2019
Background Parry–Romberg syndrome, also known as progressive hemifacial atrophy, is a rare degenerative disorder with numerous distinctive clinical presentations. It is usually slowly progressive, occurring more in females, and affects primarily one side

A mesh-free algorithm for ROF model [PDF]

EURASIP Journal on Advances in Signal Processing, 2017
Abstract The total variation (TV) denoising method is a PDE-based technique that preserves the edges well but has undesirable staircase effect in some cases, namely, the translation of smooth regions (ramps) into piecewise constant regions (stairs). This paper introduces a novel mesh-free approach using TV (ROF model) regularization and radial basis ...

Investigation of Optical Modulators in Optimized Nonlinear Compensated LTE RoF System [PDF]

, 2014
In this paper, we investigate a nonlinear compensation technique with two different architectures using direct modulation (DM) and external modulation (EM) techniques, termed as DM based frequency dithering (DMFD) and EM based frequency dithering (EMFD).

A ketogenic diet normalizes interictal cortical but not subcortical responsivity in migraineurs

BMC Neurology, 2019
Background A short ketogenic diet (KD) treatment can prevent migraine attacks and correct excessive cortical response. Here, we aim to prove if the KD-related changes of cortical excitability are primarily due to cerebral cortex activity or are modulated
