Unidirectional Light Scattering With High $f/b$ at Optical Frequencies Based on Coupled Nanoantennas

open access: yesIEEE Access, 2019
We propose an optically coupled nanoantenna which contains an asymmetric dimer of core-dual shells nanoparticles, and the individual nanoparticle consisting of two identical metal strips that separated by a dielectric spacer known as the metal-dielectric-

The cognitive demands of second order manual control: Applications of the event related brain potential [PDF]

open access: yes, 1981
Three experiments are described in which tracking difficulty is varied in the presence of a covert tone discrimination task. Event related brain potentials (ERPs) elicited by the tones are employed as an index of the resource demands of tracking. The ERP

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 ...

Improvement of coated aluminum sheet pBRDF model based on scattering and phase function optimization

open access: yesScientific Reports, 2023
The pBRDF model is able to relate the properties of target materials to the polarization information of incident and reflected light, and is an important basis for obtaining polarization information of targets in space.

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 ...

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Tracking implicit trajectories [PDF]

open access: yes, 1995
Output tracking of implcitly defined reference trajectories is examined. A continuous-time nonlinear dynamical system is constructed that produces explicit estimates of time-varying implicit trajectories.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

RLita: A Region-Level Image–Text Alignment Method for Remote Sensing Foundation Model

open access: yesRemote Sensing
The foundation model fine-tuning optimization method has gradually become a research hotspot due to the development of generative pretrained transformer. However, compared to natural scene images, remote sensing images have a wide range of spatial scales,

Reducing attrition in panel studies in developing countries.

open access: yes, 2004
BACKGROUND: Panel studies offer repeated observations of individuals over time, but the mobility of populations in the developing world often causes attrition in panel studies.
