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

open access: yesFEBS 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

New topology for voltage balancing in railway substations [PDF]

open access: yes, 2012
This paper deals with a new technique of voltage unbalance compensation for single phase railway substations. Using the concept of Chopper Controlled Impedance, the authors study the feasibility of an active Steinmetz circuit based on AC choppers.

Modified phase-shifted PWM control for flying capacitor multilevel converters [PDF]

open access: yes, 2007
The issue of voltage imbalance remains a challenge for the flying capacitor multilevel converter. The phase-shifted pulsewidth modulation (PS-PWM) method has a certain degree of self-balancing properties.

Coordinated electric vehicle charging to reduce losses without network impedances

open access: yesIET Smart Grid, 2020
This study proposes a method of coordinating electric vehicle charging to reduce losses in a distribution system, using only knowledge of the phase that each charger is connected to.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Recent and Ancient Signature of Balancing Selection around the S-Locus in Arabidopsis halleri and A. lyrata [PDF]

open access: yes, 2013
Balancing selection can maintain different alleles over long evolutionary times. Beyond this direct effect on the molecular targets of selection, balancing selection is also expected to increase neutral polymorphism in linked genome regions, in inverse ...

Two-Way Power Flow Balancing in Three-Phase Three-Wire Networks by Unbalanced Capacitive Shunt Compensation

open access: yesApplied Sciences
Developed to achieve the balancing of three-phase loads and improve their power factor, the BCC (Balancing Capacitive Compensator) is presented in this paper as having a broader capability, namely that of balancing the two-way power flow.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Harmonic Identification by DQ Axis with Fourier Method for Active Power Filters [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2006
This paper proposes a new method of harmonic identification named DQ axis with Fourier (DQF) method. It lies on the basis of the DQ axis method enhanced by the sliding window Fourier analysis (SWFA).
