Quantum structural phase transition in chains of interacting atoms

, 2010
A quasi one--dimensional system of trapped, repulsively interacting atoms (e.g., an ion chain) exhibits a structural phase transition from a linear chain to a zigzag structure, tuned by reducing the transverse trap potential or increasing the particle ...

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

Molecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

European Code Against Cancer, 5th edition – hormone replacement therapy, other common medical therapies and cancer

Molecular Oncology, EarlyView.
The 5th edition of the European Code Against Cancer (ECAC5) contains 14 recommendations on cancer prevention. Here, we update the cancer prevention recommendations regarding the use of hormone replacement therapy (HRT), which is positioned as recommendation number 13 of the ECAC5.

Range of semilinear operators for systems at resonance

Electronic Journal of Differential Equations, 2012
For a vector function $u:mathbb{R} o mathbb{R}^N $ we consider the system $$displaylines{ u''(t)+ abla G(u(t))= p(t)cr u(t)=u(t+T), }$$ where $G: mathbb{R}^N o mathbb{R}$ is a $C^1$ function.

Quantum Criticality of Topological Phase Transitions in 3D Interacting Electronic Systems

, 2014
Topological phase transitions in condensed matters accompany emerging singularities of the electronic wave function, often manifested by gap-closing points in the momentum space.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Heteroclinic orbits of a second order nonlinear difference equation

Electronic Journal of Differential Equations, 2017
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.

Key role for inhibins in effective T cell activation, migration and Th17 differentiation

FEBS Open Bio, EarlyView.
Activins/inhibins modulate immune responses. Here, we show that inhibins can be produced very early after T cell activation and can act in an autocrine way, favoring Th1 versus Th17 differentiation and CCL19/CCL21 mediated migration. Recombinant inhibin A can restore the Th1/Th17 balance, highlighting the role of inhibins as key regulators of T cell ...

A modified zero energy critical point theory with applications to several nonlocal problems

Electronic Journal of Qualitative Theory of Differential Equations
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.

Critical Exponents of the Superconducting Phase Transition

, 1995
We study the critical exponents of the superconducting phase transition in the context of renormalization group theory starting from a dual formulation of the Ginzburg-Landau theory. The dual formulation describes a loop gas of Abrikosov flux tubes which
