Quasiperiodic Poincare Persistence at High Degeneracy [PDF]

, 2023
For Hamiltonian systems with degeneracy of any higher order, we study the persistence of resonant invariant tori, which as some lower-dimensional invariant tori might be elliptic, hyperbolic or of mixed types.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

Sharp viscous shock waves for relaxation model with degeneracy

Advances in Nonlinear Analysis
This article is concerned with a relaxation model with degeneracy. Different from the existing studies on the regular viscous shock waves, we recognize that when the sub-characteristic condition is degenerate, the dynamical system possesses sharp viscous

Improvement of Degeneracy for Hybrid Transducer

, 2009
In this paper, a new design of hybrid transducer consisting of individual longitudinal and torsional vibrators is investigated. Degeneracy approach for searching the same resonant frequency of both the longitudinal and torsional ceramic vibrators is the ...

MARK4 enhances stress granule formation under oxidative stress and increases tau accumulation

FEBS Open Bio, EarlyView.
MARK4 (red dots) localizes to stress granules (orange dots) and promotes their formation under oxidative stress by modulating TIA1 (blue dots). MARK4 and TIA1 synergistically increase tau (purple) accumulation, and the reduction of the TIA1 ortholog suppresses neurodegeneration in a fly model.

Postoptimal analysis in the coefficients matrix of piecewise linear fractional programming problems with non-degenerate optimal solution [PDF]

Opuscula Mathematica, 2010
In this paper, we discuss how changes in the coefficients matrix of piecewise linear fractional programming problems affect the non-degenerate optimal solution.

Three Merry Roads to T-Violation [PDF]

, 2013
This paper is a tour of how the laws of nature can distinguish between the past and the future, or be T-violating. I argue that, in terms of the basic argumentative structure, there are basically just three approaches currently being explored.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

A Note on Contraction Degeneracy [PDF]

, 2004
The parameter contraction degeneracy --- the maximum minimum degree over all minors of a graph --- is a treewidth lower bound and was first defined in [3]. In experiments it was shown that this lower bound improves upon other treewidth lower bounds [3].

Exchange degeneracy and backward superconvergence in NN̅ scattering

, 1968
The treatment of a weak u channel by the usual prescription of exchange degeneracy, based on a potential-theory model, is shown to violate crossing badly.
