Phase separation in gene transcription control

open access: yesActa Biochimica et Biophysica Sinica, 2023
Phase separation provides a general mechanism for the formation of biomolecular condensates, and it plays a vital role in regulating diverse cellular processes, including gene expression.

Redox and acid properties of MnV2Ox/TiO2 catalysts synthesized by assistance of microwave for NO selective catalytic reduction by ammonia

open access: yesChemical Engineering Journal Advances, 2021
Supported manganese vanadate catalysts for selective catalytic reduction of NOx by ammonia (NH3-SCR) with wide temperature window were fabricated by assistance of microwave. Vanadate dispersed well on the surface of TiO2, giving an enhanced activity in a

Separate to operate: control of centrosome positioning and separation [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2014
The centrosome is the main microtubule (MT)-organizing centre of animal cells. It consists of two centrioles and a multi-layered proteinaceous structure that surrounds the centrioles, the so-called pericentriolar material. Centrosomes promote de novo assembly of MTs and thus play important roles in Golgi organization, cell polarity, cell motility and ...

Comparison of Separation Control Mechanisms for Synthetic Jet and Plasma Actuators

open access: yesActuators, 2023
This study numerically investigated the mechanisms of separation control using a synthetic jet (SJ) and plasma actuator (PA) around an NACA0015 airfoil at the chord Reynolds number of 63,000.

ON THE SEPARATION PRINCIPLE IN QUANTUM CONTROL [PDF]

open access: yesQuantum Stochastics and Information, 2008
It is well known that quantum continuous observations and nonlinear filtering can be developed within the framework of the quantum stochastic calculus of Hudson-Parthasarathy. The addition of real-time feedback control has been discussed by many authors, but the foundations of the theory still appear to be relatively undeveloped.

Liquid Phase Separation Controlled by pH [PDF]

open access: yesBiophysical Journal, 2020
We present a minimal model to study liquid phase separation in a fixed pH ensemble. The model describes a mixture composed of macromolecules that exist in three different charge states and have a tendency to phase separate. We introduce the pH dependence of phase separation by means of a set of reactions describing the protonation and deprotonation of ...

Effects of contraction ratio on loss reduction of the flow in the reducing elbow duct with a weir-shaped obstacle

open access: yesJournal of Fluid Science and Technology, 2023
90-degree elbow pipe/duct is one of the piping element which is used frequently in industrial apparatus. The separated flow which occurs at inner corner of elbow part and the secondary flow which occurs at the elbow and its downstream cause significant ...
