FMint: Bridging Human Designed and Data Pretrained Models for Differential Equation Foundation Model for Dynamical Simulation

Advanced Theory and Simulations, EarlyView.
FMint is introduced as a multi‐modal foundation model that integrates human‐designed solvers and data‐driven methods for fast, accurate simulation of dynamical systems. FMint leverages in‐context learning within a transformer‐based framework to refine coarse numerical solutions.

Lecithin Alleviates Memory Deficits and Muscle Attenuation in Chinese Older Adults and SAMP8 Mice

Advanced Science, EarlyView.
This study opens a new avenue for safeguarding cognition and muscle health, averting disability in older age, and treating age‐related pathologies through lecithin supplementation. It serves as a promising nonpharmacological intervention for the crosstalk of muscle and cognition.

The Nuclear Localization of ACLY Guards Early Embryo Development Through Recruiting P300 and HAT1 to Promote Histone Acetylation and Transcription

Advanced Science, EarlyView.
ACLY is vital for early embryo development. IGF‐1 activates AKT to phosphorylate ACLY, driving its nuclear localization and recruitment of HATs (P300/HAT1), boosting acetyl‐CoA production and histone acetylation for transcriptional activation. Conversely, ACLY deficiency (via knockdown, knockout, or AKT inhibition) reduces nuclear acetyl‐CoA, disrupts ...

Bifurcation Analysis in Population Genetics Model with Partial Selfing

Abstract and Applied Analysis, 2013
A new model which allows both the effect of partial selfing selection and an exponential function of the expected payoff is considered. This combines ideas from genetics and evolutionary game theory.

Network Desynchronization with Sine Waves: from Synchrony to Asynchrony by Periodic Stimulation

Advanced Science, EarlyView.
Exogenous alternating current fields are explored and interact with cerebral cortex slow waves in vitro and in silico. Varying frequency and amplitude of sine waves result in distinct network dynamics, from phase‐locking and entrainment to desynchronization. These responses occupy specific regions within the parameter space.

Global stability and bifurcation analysis of a delayed predator-prey system with prey immigration

Electronic Journal of Qualitative Theory of Differential Equations, 2016
A delayed predator-prey system with a constant rate immigration is considered. Local and global stability of the equilibria are studied, a fixed point bifurcation appears near the boundary equilibrium and Hopf bifurcation occurs near the positive ...

Bifurcation in Rotational Spectra of Nonlinear AB$_2$ Molecules

, 1995
A classical microscopic theory of rovibrational motion at high angular momenta in symmetrical non-linear molecules AB$_2$ is derived within the framework of small oscillations near the stationary states of a rotating molecule.
