Critical analysis of the theory of movement in movement in Allameh Tabatabai's view point [PDF]
Sadr al-Matahin proposed the movement in the category of substance by proposing the theory of substance movement. But he, like other philosophers, did not accept the movement in other categories, especially in categories whose individuals are gradually ...

The de Haas van Alphen effect near a quantum critical end point in Sr₃Ru₂O₇
Highly correlated electron materials are systems in which many new states of matter can emerge. A particular situation which favours the formation of exotic phases of the electron liquid in complex materials is that where a quantum critical point (QCP ...

Critical exponents of the pair contact process with diffusion
We study the pair contact process with diffusion (PCPD) using Monte Carlo simulations, and concentrate on the decay of the particle density ρ with time, near its critical point, which is assumed to follow ρ(t) ct− +c2t− 2+. . ...

Fermionic quantum critical point of spinless fermions on a honeycomb lattice [PDF]
Spinless fermions on a honeycomb lattice provide a minimal realization of lattice Dirac fermions. Repulsive interactions between nearest neighbors drive a quantum phase transition from a Dirac semimetal to a charge-density-wave state through a fermionic ...

Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Heteroclinic orbits of a second order nonlinear difference equation
This article concerns a second-order nonlinear difference equation. By using critical point theory, the existence of two heteroclinic orbits is obtained. The main method used is variational.

Critical Point Theory for Indefinite Functionals with Symmetries
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.

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

A modified zero energy critical point theory with applications to several nonlocal problems
In this paper, we devote ourselves to considering a modified zero energy critical point theory for a specific set of functionals denoted as $\Phi_{\mu}$, defined within the confines of a uniformly convex Banach space.

Some remarks on the critical point theory
In this paper we discuss some problems about critical point theory. In the first part of the paper we study existence and multiplicity results of semilinear second order elliptic equation: $$ \begin{cases} -\Delta u=f(x,u) &\text{for } x\in \Omega, \\ u ...
