The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Improving Vision Transformers by Revisiting High-Frequency Components

open access: yes, 2022
The transformer models have shown promising effectiveness in dealing with various vision tasks. However, compared with training Convolutional Neural Network (CNN) models, training Vision Transformer (ViT) models is more difficult and relies on the large-scale training set.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

The measurement of very low conductivity and dielectric loss in XLPE cables: A possible method to detect degradation due to thermal aging [PDF]

open access: yes, 2011
The dielectric response of crosslinked polyethylene (XLPE) insulated, miniature power cables, extruded with inner and outer semicons, was measured over the frequency range 10-4 to 104 Hz at temperatures from 20 to 100 °C.

Transformers in High-Frequency Trading

open access: yesJournal of Physics: Conference Series
Abstract Transformer is a deep learning model that, having an innovative performance in many tasks, has uniquely and significantly modified all the cast of mind of the AI scientific community. In this paper, we introduce a Transformer model that is applied to 1-minute timescale in the EURUSD and GBPUSD instruments of forex trading.

High-Frequency Lithium Acetate Transformation of Schizosaccharomyces pombe [PDF]

open access: yes, 2018
The introduction of ectopic DNA, such as plasmids, into yeast cells has for decades been a critical protocol for the study of this eukaryotic model system. We describe here an efficient transformation procedure for use in the fission yeast Schizosaccharomyces pombe.
