An extension theorem for sober spaces and the Goldman topology
International Journal of Mathematics and Mathematical Sciences, 2003 Goldman points of a topological space are defined in order to extend the notion of prime G-ideals of a ring. We associate to any topological space a new topology called Goldman topology. For sober spaces, we prove an extension theorem of continuous maps.

Positive solutions of a second-order nonlinear Robin problem involving the first-order derivative
Advances in Difference Equations, 2021 This paper is concerned with the second-order nonlinear Robin problem involving the first-order derivative: { u ″ + f ( t , u , u ′ ) = 0 , u ( 0 ) = u ′ ( 1 ) − α u ( 1 ) = 0 , $$ \textstyle\begin{cases} u''+f(t,u,u^{\prime })=0, \\ u(0)=u'(1)-\alpha u ...

FEBS 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 ...

Unconscious Presentation of Object Affordances Evokes a Negative Compatibility Effect [PDF]
i-Perception, 2014 According to Gibson's (1979) theory of “affordances”, the environment is constantly bombarding the viewer with a multitude of possible actions. More recently, it has been suggested that the simple viewing of an object can automatically elicit motor plans

PARP inhibitors induce a senescence phenotype in non‐small cell lung carcinoma cell lines
FEBS Open Bio, EarlyView.Talazoparib is the most potent inducer of senescence among different PARP1 inhibitors in human NSCLC cells. In the absence of PARP, no senescence phenotype was observed, demonstrating that PARP1 is necessary for the induction of senescence by this inhibitor.

Probing R-parity violation in B-meson decays to a baryon and a light neutralino
Journal of High Energy Physics, 2023 We propose a search for B meson decays to a baryon plus missing energy at the Belle II experiment to probe supersymmetry with a GeV-scale lightest neutralino χ ~ 1 0 $$ {\overset{\sim }{\chi}}_1^0 $$ and R-parity violation (RPV).

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

, 2004 We investigate the critical properties of the $S=1/2$ bond-alternating spin chain with a next-nearest-neighbor interaction in magnetic fields. By the numerical calculation and the exact solution based on the effective Hamiltonian, we show that there is a

On the decomposition of self-dual codes over F2+uF2 with an automorphism of odd prime order
Finite Fields Their Appl., 2007 We present a general theory of decomposing self-dual codes over F"2+uF"2 that have an automorphism of odd prime order. Using this decomposition we classify all Lee-extremal/optimal self-dual codes of lengths 9 to 16 with an odd order automorphism and ...

FEBS Open Bio, EarlyView.This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.
