A Low-Noise Current-Squared Delta-Sigma-Modulation Boost Converter Suitable for Low-Voltage Wireless Sensor Networks With Transient-Accelerated Techniques

IEEE Access
This paper presents a low-noise current-squared delta-sigma-modulation boost converter suitable for low-voltage wireless sensor networks with transient-accelerated techniques. There are two current-controlled loops and two voltage-controlled loops in the

High spatio-temporal resolution pollutant measurements of on-board vehicle emissions using ultra-fast response gas analyzers [PDF]

Atmospheric Measurement Techniques, 2018
Existing ultra-fast response engine exhaust emissions analyzers have been adapted for on-board vehicle use combined with GPS data. We present, for the first time, how high spatio-temporal resolution data products allow transient features associated ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Numerical study on temperature response of microheater and evolution characteristics of superheated zone under fast transient heating

Case Studies in Thermal Engineering
The nucleate boiling process that occurs on the surface of a microheater immersed in a liquid pool under fast transient heating conditions can be regarded as homogeneous or near-homogeneous nucleation, exhibiting a significant difference when compared to

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

A switched‐capacitor‐assisted wireless power transfer system with regulating TX power and fast global loop

Electronics Letters, 2022
Wireless power transfer systems demand a regulating transmitter (TX) for global loop control and also a regulating receiver (RX) for its local loop. This design broadens the TX output power range, by merging a switched capacitor (SC) circuit with only 3 ...

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Transient response improvement of predictive control under time domain constraints

Heliyon
In this paper, a novel predictive controller design approach within augmented structure base on convex optimization of an extra parameter is proposed in order to improve the transient response of discrete-time linear systems subject to input constraints.

Transient power equalization control strategy of virtual synchronous generator in isolated island microgrid with heterogeneous power supply

Scientific Reports, 2023
In the parallel supply system of synchronous generator and virtual synchronous generator, the physical structure and control structure of the two kinds of power supply are quite different, and it is difficult to distribute the transient power of the two ...
