Perceived Blur in Naturally-Contoured Images Depends on Phase

Frontiers in Psychology, 2010
Perceived blur is an important measure of image quality and clinical visual function. The magnitude of image blur varies across space and time under natural viewing conditions owing to changes in pupil size and accommodation.

Hepatoma‐Derived Growth Factor Coordinates STAT3 Pathway and Exosome‐Mediated Intrahepatic Crosstalk to Control Hepatic Steatosis and MASLD

Advanced Science, EarlyView.
Hepatic HDGF as a key mediator in coordinating hepatic steatosis and intrahepatic crosstalk in MASLD. Activation of HDGF facilitates its interaction with both STAT3 and S6K1, driving the S6K1‐dependent STAT3 phosphorylation and subsequently enhancing hepatic lipogenesis.

Nonsmooth and level-resolved dynamics illustrated with a periodically driven tight-binding model

ScienceOpen Research, 2015
We point out that in the first-order time-dependent perturbation theory, the transition probability may behave nonsmoothly in time and have kinks periodically.

Sparse Bayesian Relevance Vector Machine Identification Modeling and Its Application to Ship Maneuvering Motion Prediction

Journal of Marine Science and Engineering, 2023
In order to establish a sparse and accurate ship motion prediction model, a novel Bayesian probability prediction model based on relevance vector machine (RVM) was proposed for nonparametric modeling.

DTX3L Inhibits the EMT, Metastasis, and Stem‐Like Features of Gastric Cancer Through Promoting GSK‐3β Dependent SNAI1 Decay

Advanced Science, EarlyView.
This research identifies DTX3L as a critical tumor suppressor that inhibits epithelial‐mesenchymal transition (EMT), invasion and metastasis in gastric cancer. By functioning as an E3 ubiquitin ligase, DTX3L targets the master EMT regulator SNAI1 for GSK‐3β‐dependent proteasomal degradation.

A New Tailored Sinc Pulse and Its Use for Multiband Pulse Design [PDF]

, 2016
Purpose: Among RF pulses, a sinc pulse is typically used for slice selection due to its frequency-selective feature. When a sinc pulse is implemented in practice, it needs to be apodized to avoid truncation artifacts at the expense of broadening the ...

Dynamic Harmonic Synchrophasor Estimator Based on Sinc Interpolation Functions [PDF]

IEEE Transactions on Instrumentation and Measurement, 2019
This paper introduces a new dynamic harmonic synchrophasor estimator (DHSE) based on the Shannon sampling theorem. Each dynamic harmonic phasor is modeled as a weighted sum of a series of sinc interpolation functions. Based on this, a bank of finite impulse response filters is designed.

Kinsenoside Targets IDH1 to Restore Microglial Immune‐Metabolic Homeostasis for Alzheimer's Disease Therapy

Advanced Science, EarlyView.
Dysregulated TCA cycle contributes to Alzheimer's disease (AD) pathogenesis. Here, we show that microglial isocitrate dehydrogenase 1 (IDH1) is a critical driver. Elevated IDH1 disrupts citrate metabolism and mitochondrial function, exacerbating AD pathology.
