Model‐free adaptive control for ultracapacitor based three‐phase interleaved bidirectional DC–DC converter

IET Power Electronics, 2023
The lack of an accurate mathematical model of non‐linear systems, such as bidirectional DC–DC converters, brings certain limits to design a formidable controller for such systems. This article proposes a model‐free adaptive control (MFAC) approach for an

Two distinct alcohol dehydrogenase classes mediate bacterial 2‐hydroxyethylphosphonate catabolism

Protein Science, Volume 35, Issue 10, October 2026.
Abstract Phosphonates are molecules containing a direct carbon‐phosphorus bond. In nature, these compounds are produced by a variety of organisms, and many environmental microbes are able to degrade specific phosphonates and feed on them. This work focuses on 2‐hydroxyethylphosphonate (HEP)—a natural compound that is found frequently in the environment,

Multi-state and Interleaved Converters With Passive Impedances for Current Sharing

Eletrônica de Potência, 2014
This paper presents multilevel switching cells that allow the generation of high-power nonisolated dc-dc, ac-dc, dc-ac, and ac- ac converters. The cells are classified in two groups: multi-state switching cells (MSSC) based on autotransformer and ...

Personalized Network‐Guided Neuromodulation Enhances Human Working Memory

Advanced Science, Volume 13, Issue 49, 3 September 2026.
A personalized neuromodulation framework combining individualized functional brain network targeting with real‐time neural decoding is introduced. Using concurrent TMS–fMRI, participant‐specific stimulation targets and optimal frequencies are identified. Only optimal‐frequency stimulation improves working memory across sessions.

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1206-1218, September 2026.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Integrative Analysis Uncover the Effects and Multi‐Omics Features of Thigh Muscle Fat Infiltration

Aging Cell, Volume 25, Issue 9, September 2026.
Thigh muscle fat infiltration (TMFI), estimated from MRI, is associated with increased mortality and diseases affecting multiple organ systems and mediates the effects of lifestyle factors on health. Multi‐omics analyses delineate the genetic, cellular, transcriptional, proteomic, and metabolic architecture of TMFI.
