Saturation and Critical Phenomena in DIS [PDF]

open access: yes, 2009
It is argued that the expected turn-down in $x- Q^2$ of the cross sections (structure functions $F_2(x,Q^2)$), assumed to result from the saturation of parton densities in the nucleon, is related to a phase transition from the (almost) ideal partonic gas,

Overview of molecular signatures of senescence and associated resources: pros and cons

open access: yesFEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Critical phenomena near the antiferromagnetic quantum critical point of Heavy-Fermions

open access: yes, 2000
We present a study of the critical phenomena around the quantum critical point in heavy-fermion systems. In the framework of the S=1/2 Kondo lattice model, we introduce an extended decoupling scheme of the Kondo interaction which allows one to treat the ...

The cooperative regulation of miR‐221 by APE1 and AUF1 impacts p27Kip1 defining a miR signature relevant for cervical cancer

open access: yesFEBS Open Bio, EarlyView.
A regulatory axis involving APE1, AUF1, and miR‐221 is proposed. Pri‐miR‐221 is processed by DROSHA and DICER to generate mature miR‐221, which targets p27Kip1 mRNA. APE1 and AUF1 compete for pre‐miR‐221 binding. Reduced APE1/AUF1 levels impair miR‐221 biogenesis, decrease p27Kip1 mRNA degradation, and promote cell cycle progression, chemoresistance ...

Critical phenomena in N=4 SYM plasma

open access: yes, 2010
Strongly coupled N=4 supersymmetric Yang-Mills plasma at finite temperature and chemical potential for an R-symmetry charge undergoes a second order phase transition. We demonstrate that this phase transition is of the mean field theory type.

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes

open access: yesFEBS Open Bio, EarlyView.
We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

Asymptotics of critical conditions in one combustion model

open access: yesВестник Самарского университета: Естественнонаучная серия
The work is devoted to solving the problem of critical conditions for an autocatalytic combustion model, taking into account the consumption of reagent and oxidizer.

Scaling Laws in the Fine-Scale Structure of Range Margins

open access: yesMathematics, 2018
Margins of the geographic distributions of species are important regions in terms of ecological and evolutionary processes, including the species’ response to climate change. This paper reviews some spatially explicit metapopulation models of range

Critical phenomena in the AdS/CFT duality

open access: yes, 2010
We review black holes with second-order phase transition in string theory (R-charged black holes and holographic superconductors) and review their static and dynamic critical phenomena.

Critical phenomena and critical relations

open access: yes, 2002
We consider systems which exhibit typical critical dependence of the specific heat: $ c\varpropto (T_C-T)^{- }$ ($TT_C$) where $ $,$ ^{\prime}$ are critical exponents ($ = $ for $ c= c_{p,N},$ $ =\bar $ for $ c= c_{V,N}$), as well as, the case when $ c\varpropto (\ln \mid T_C-T\mid)^a$ ($% a=\frac 13$, uniaxial ferroelectrics; $a=1 ...
