Efficient Data Transmission Using MPPM Dimming Control in Indoor Visible Light Communication

IEEE Photonics Journal, 2015
In conventional visible light communication (VLC) dimming control systems utilizing pulse width modulation (PWM), reducing the duty cycle will push up the receiver sensitivity requirement if the transmission rate is kept constant.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

In Situ Biofilm Monitoring Using a Heat Transfer Sensor: The Impact of Flow Velocity in a Pipe and Planar System

Biosensors
Industrially applied bioelectrochemical systems require long-term stable operation, and hence the control of biofilm accumulation on the electrodes. An optimized application of biofilm control mechanisms presupposes on-line, in-situ monitoring of the ...

Expanding biological control to bioelectronics with machine learning

APL Materials, 2020
Bioelectronics integrates electronic devices and biological systems with the ability to monitor and control biological processes. From homeostasis to sensorimotor reflexes, closed-loop control with feedback is a staple of most biological systems and ...

Optimally sensitive controller for digital systems

Electronics Letters, 1979
A scheme is developed which allows an optimal control policy to be maintained in cases where the parameters of the controlled system deviate by a small amount from the values expected. This is achieved by augmenting the nominally correct controller design to allow updating of the system control vector on the basis of observed deviations from the ideal ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Automatic Control System of the Evaporator in the Technology of Spent Nuclear Fuel Processing

Chemical Engineering Transactions, 2017
The operation of the radiochemical plant is impossible without high-quality automatic control systems. In the technologies of spent nuclear fuel reprocessing, the method of continuous evaporation is often used for a solution conditioning.

A Study on Zero Sensitive Control System

IEEJ Transactions on Electronics, Information and Systems, 2009
Since system uncertainties are unavoidable in the modeling, control systems are generally required to be insensitive to these uncertainties. In this paper, the problem of control system design which is insensitive to these uncertainties is studied, and a structure of system uncertainties which do not affect the control performance is clarified.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
