Radially Excited AdS5 Black Holes in Einstein–Maxwell–Chern–Simons Theory

Entropy, 2017
In the large coupling regime of the 5-dimensional Einstein–Maxwell–Chern–Simons theory, charged and rotating cohomogeneity-1 black holes form sequences of extremal and non-extremal radially excited configurations.

Extremal solutions of quasilinear parabolic subdifferential inclusions

Differential and Integral Equations, 2003
The authors consider the following initial boundary value problem for the quasilinear parabolic inclusion: \[ \frac{\partial u}{\partial t}+Au+\beta(\cdot,u)\ni Fu+h \quad {\text{in}} \;Q, \qquad u(x,0)=0\;{\text{in}}\;\Omega \quad{\text{and}}\;u=0\;{\text{on}}\;\Gamma, \] where \(\Omega\subseteq\mathbb{R}^N\) is a bounded domain with Lipschitz ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Electromagnetic quasitopological gravities

Journal of High Energy Physics, 2020
We identify a set of higher-derivative extensions of Einstein-Maxwell theory that allow for spherically symmetric charged solutions characterized by a single metric function f (r) = −g tt = 1/g rr .

NUT-Charged Black Holes in Gauss-Bonnet Gravity

, 2005
We investigate the existence of Taub-NUT/bolt solutions in Gauss-Bonnet gravity and obtain the general form of these solutions in $d$ dimensions. We find that for all non-extremal NUT solutions of Einstein gravity having no curvature singularity at $r=N$,

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

Molecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

First-order flow equations for extremal black holes in very special geometry

, 2007
We construct interpolating solutions describing single-center static extremal non-supersymmetric black holes in four-dimensional N=2 supergravity theories with cubic prepotentials.

Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

Molecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...

Charged black holes in non-linear Q-clouds with O(3) symmetry

Physics Letters B, 2020
We construct charged soliton solutions around spherical charged black holes with no angular momentum in asymptotically flat spacetime. These solutions are non-linear generalizations of charged scalar clouds, dubbed Q-clouds, and they do not contradict ...

Extremal solutions of measure differential equations

Journal of Mathematical Analysis and Applications, 2016
The paper concerns the existence of the least and the greatest solutions for measure differential equations. The relationship with the notions of lower and upper solution is also investigated. Interesting examples are provided to motivate the key assumptions in each result.
