Strain analysis of stator coil holders for permanent magnet spherical motors

open access: yes工程科学学报, 2015
An analytical model of air-gap flux density and the Lorenz force law were used to establish radial and tangential electro-magnetic force models in the spherical coordinate system for the stator coils. Then, a finite element model of the stator casing and

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Structural determinants of coiled coil mechanics

open access: yesPhysical Chemistry Chemical Physics, 2019
In shear geometry, the sequence–structure–mechanics relationship of rationally designed coiled coil heterodimers is determined by the helix propensity of the individual helices and the packing density at the hydrophobic core.

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Proposed methodology for online frequency response analysis based on magnetic coupling to detect winding deformations in transformers

open access: yesHigh Voltage, 2019
Frequency response analysis is widely used as a method for the offline diagnosis of winding deformations in power transformers. To apply it to a working transformer, people need to determine how to inject the excitation signal and measure the response ...
