Three dimensional Lifshitz-like black hole in a special class of F(R) gravity

open access: yesPhysics Letters B, 2020
Regarding a special class of pure F(R) gravity in three dimensions, we obtain, analytically, Lifshitz-like black hole solutions. We check the geometrical properties of the solutions which behave such as charged BTZ black holes in special limit.

The Role of Elementary Dimensions in the Creation of the Source of Elementary Particles

open access: yesUKH Journal of Science and Engineering, 2020
It is agreed that before the creation of particles, space was completely devoid of matter and radiation. In this study, we assume that the absolute void comprises 4 dimensions, namely 3 spatial dimensions and a force equivalent representing the factor of

Isolated neutron stars and studies of their interiors

open access: yes, 2011
In these lectures presented at Baikal summer school on physics of elementary particles and astrophysics 2011, I present a wide view of neutron star astrophysics with special attention paid to young isolated compact objects and studies of the properties ...

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

A Eterna Busca do Indivisível: do Átomo Filosófico aos Quarks e Léptons The eternal search for the indivisible: from philosophical atom to quarks and leptons

open access: yesQuímica Nova, 1997
The fascinating search of the inner boundaries of the Universe, has been entangled, since the birth of greek philosophy 25 centuries ago, with the main epistemological changes in the History of Science.

Plasma-like Description for Elementary and Composite Quantum Particles

open access: yesEntropy, 2022
Schrödinger noticed in 1952 that a scalar complex wave function can be made real by a gauge transformation. The author showed recently that one real function is also enough to describe matter in the Dirac equation in an arbitrary electromagnetic or Yang ...

The Concept of Mass in the Einstein Year [PDF]

open access: yes, 2006
Various facets of the concept of mass are discussed. The masses of elementary particles and the search for higgs. The masses of hadrons. The pedagogical virus of relativistic mass.

Evaluation of synaptotagmin‐1 action models by all‐atom molecular dynamics simulations

open access: yesFEBS Open Bio, EarlyView.
We used molecular dynamics simulations to test models proposing that synaptotagmin‐1 facilitates membrane fusion by perturbing lipid bilayers, inducing membrane curvature and/or bridging membranes. The simulations show that synaptotagmin‐1 C2‐domains placed near the site of fusion hinder the ability of SNARE complexes to bring the membranes together ...

Characterisation of the role played by ELMO1, GPR141 and the intergenic polymorphism rs918980 in Fuchs' dystrophy in the Indian population

open access: yesFEBS Open Bio, EarlyView.
This study reports the upregulation of ELMO1 and GPR141 in human Fuchs' endothelial corneal dystrophy (FECD) corneal endothelium and ultraviolet A‐induced FECD mice model. A genetic association of an intergenic single nucleotide polymorphism rs918980 present between both genes is observed with FECD in the Indian population.

The Atomic hypothesis: Physical consequences [PDF]

open access: yesJ.Phys.A41:304022,2008, 2007
The hypothesis that matter is made of some ultimate and indivisible objects, together the restricted relativity principle, establishes a constraint on the kind of variables we are allowed to use for the variational description of elementary particles. We consider that the atomic hypothesis not only states the indivisibility of elementary particles, but
