Critical exponents values for fluids and linear scaled equation of state

open access: yesLittera Scripta, 2011
The behavior of substance in the vicinity of a critical point is the focus of great scienti fic interest. A liquid-liquid phase transition in the supercooled region could influence biochemical or precipitation processes. It is interesting that water in a

Imprints of a critical point on photon emission

open access: yes, 2015
The linear sigma model with linearized fluctuations of all involved fields facilitates the onset of a sequence of first-order phase transitions at a critical point. This phase structure has distinctive imprints on the photon emission rates. We argue that

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Quantum critical point in a periodic Anderson model

open access: yes, 2001
We investigate the symmetric Periodic Anderson Model (PAM) on a three-dimensional cubic lattice with nearest-neighbor hopping and hybridization matrix elements. Using Gutzwiller's variational method and the Hubbard-III approximation (which corresponds to

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Superlinear fractional boundary value problems without the Ambrosetti-Rabinowitz condition

open access: yesElectronic Journal of Differential Equations, 2018
In this article, by means of a direct variational approach and the theory of the fractional differential space, we prove the existence of a nontrivial solution for superlinear fractional boundary value problems without Ambrosetti and Rabinowitz ...

Remarks on some fourth-order boundary value problems with non-monotone increasing eigenvalue sequences

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
By $Z_{2}$-index theory, the existence and multiplicity of solutions for some fourth-order boundary value problems $$ \begin{cases} u^{(4)}+au''=\mu u+F_{u}(t,u ...
