Dark Energy and Tachyon Field in Bianchi Type-V Space-time [PDF]
Mod. Phys. Lett. A, Vol. 30, No. 1 (2015) 1550008, 2014 In this paper, we consider Bianchi type-V space-time and study a cosmological model of dark energy based on Tachyon scalar field. We assumed three different kinds of matter without possibility of interaction with scalar dark energy. Assuming power law Hubble parameter in terms of scale factor we obtain evolution of scalar field, scalar potential and ...

Scalar Dark Matter Analysis of 6-Dimensional Effective Field Theory [PDF]
arXiv, 2023 We give a prescription how high energy physics tools can be used to perform scalar dark matter analysis. We also present the analysis results of scalar dark matter in the context of 6 dimensional Effective Field Theory.

Molecular Oncology, EarlyView.TGF‐β has a complex role in cancer, exhibiting both tumor‐suppressive and tumor‐promoting properties. Using a series of differentiated tumoroids, derived from different stages and mutational background of colorectal cancer patients, we replicate this duality of TGF‐β in vitro. Notably, the atypical but highly aggressive KRASQ22K mutation rendered early‐

Interacting Dark Energy in Hořava-Lifshitz Cosmology [PDF]
, 2009 In the usual Ho\v{r}ava-Lifshitz cosmological models, the scalar field is responsible for dark matter. Using an additional scalar field, Saridakis \cite{sari} has formulated Ho\v{r}ava-Lifshitz cosmology with an effective dark energy sector. In the paper \cite{sari} the scalar fields do not interact with each other, here we extend this work to the ...

Molecular 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

Baryogenesis via dark matter-induced symmetry breaking in the early Universe
Physics Letters B, 2017 We put forward a new proposal for generating the baryon asymmetry of the universe by making use of the dynamics of a U(1) scalar field coupled to dark matter.

Irreversible thermodynamic description of interacting dark energy - dark matter cosmological models [PDF]
Phys.Rev.D87:044018,2013, 2012 We investigate the interaction between dark energy and dark matter in the framework of irreversible thermodynamics of open systems with matter creation/annihilation. We consider dark energy and dark matter as an interacting two component (scalar field and "ordinary" dark matter) cosmological fluid in a homogeneous spatially flat and isotropic Friedmann-
