Criticality in Third Order Lovelock Gravity and the Butterfly effect
, 2017 We study third order Lovelock Gravity in $ D=7 $ at the critical point which three (A)dS vacua degenerate into one. We see there is not propagating graviton at the critical point. And also we compute the butterfly velocity for this theory at the critical

FEBS Letters, EarlyView.Single‐cell RNA sequencing reveals an opposite role of SLPI in basal tumors based on metastatic spread, along with shared activation of specific regulons in cancer cells and mature luminal lactocytes, as well as downregulation of MALAT1 and NEAT1 in the latter.

Critical Point Theory for Indefinite Functionals with Symmetries
Journal of Functional Analysis, 1996 Let \(X\) be a Hilbert space and \(G\) a compact Lie group acting orthogonally on \(X\). Let \(\phi \in C^1(X,\mathbb{R})\) be a strongly indefinite functional, invariant with respect to the action of \(G\). In order to find critical points of \(\phi\), the authors introduce an equivariant version of the limit relative category of \textit{G.

Some remarks on the critical point theory [PDF]
SCIENTIA SINICA Mathematica, 2016 In this paper, we give some remarks on the development of critical point theory. One is mainly concerned with Mountain Pass theorem, which is well-known in variational theory. For this reason, we make some remarks on some aspects relating to MPT. Another is related to topological methods of nonlinear problems, which have a great progress during the ...

, 1993 We study the random walk representation of the two-point function in statistical mechanics models near the critical point. Using standard scaling arguments we show that the critical exponent $\nu$ describing the vanishing of the physical mass at the ...

Imeglimin attenuates liver fibrosis by inhibiting vesicular ATP release from hepatic stellate cells
FEBS Letters, EarlyView.Imeglimin, at clinically relevant concentrations, inhibits vesicular ATP accumulation and release from hepatic stellate cells, thereby attenuating purinergic signaling and reducing fibrogenic activation. This mechanism reveals a newly identified antifibrotic action of imeglimin beyond glycemic control.

Multiple Solutions for a Nonlinear Fractional Boundary Value Problem via Critical Point Theory
Journal of Function Spaces, 2017 This paper is concerned with the existence of multiple solutions for the following nonlinear fractional boundary value problem: DT-αaxD0+αux=fx,ux, x∈0,T, u0=uT=0, where α∈1/2,1, ax∈L∞0,T with a0=ess infx∈0,Tax>0, DT-α and D0+α stand for the left and ...

Chain length dependence of the polymer-solvent critical point parameters
, 1996 We report grand canonical Monte Carlo simulations of the critical point properties of homopolymers within the Bond Fluctuation model. By employing Configurational Bias Monte Carlo methods, chain lengths of up to N=60 monomers could be studied.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Existence of homoclinic orbits for a class of nonlinear functional difference equations
Electronic Journal of Differential Equations, 2016 By using critical point theory, we prove the existence of a nontrivial homoclinic orbit for a class of nonlinear functional difference equations. Our conditions on the nonlinear term do not need to satisfy the well-known global Ambrosetti-Rabinowitz ...
