Effect of the pion field on the distributions of pressure and shear in the proton
Physics Letters B, 2022 In light of recent experimental progress in determining the pressure and shear distributions in the proton, these quantities are calculated in a model with confined quarks supplemented by the pion field required by chiral symmetry.

A global fit of the $\gamma$-ray galactic center excess within the scalar singlet Higgs portal model
, 2016 We analyse the excess in the $\gamma$-ray emission from the center of our galaxy observed by Fermi-LAT in terms of dark matter annihilation within the scalar Higgs portal model.

International Journal of Modern Physics A, 2006 More than 90% of matter in the Universe could be composed of heavy particles, which were non-relativistic, or 'cold', when they froze-out from the primordial soup. I will review current searches for these hypothetical particles, both via interactions with nuclei in deep underground detectors, and via the observation of their annihilation products in ...

Fuzzy Dark Matter and Dark Matter Halo Cores [PDF]
The Astrophysical Journal, 2020 Abstract Whereas cold dark matter (CDM) simulations predict central dark matter cusps with densities that diverge as ρ(r) ∼ 1/r, observations often indicate constant-density cores with finite central densities ρ 0 and a flat density distribution within a core radius r 0.

Molecular Oncology, EarlyView.This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Signatures of Self-Interacting Dark Matter in the Matter Power Spectrum and the CMB
, 2018 We consider a self-interacting dark matter model in which the massive dark photon mediating the self-interaction decays to light dark fermions to avoid over-closing the universe.

BRANEWORLDS AND DARK MATTER [PDF]
International Journal of Modern Physics D, 2011 Two problems related to dark matter are considered in the context of a braneworld model in which the confinement of gauge fields on the brane is achieved by invoking a confining potential. First, we show that the virial mass discrepancy can be addressed if the conserved geometrical term appearing in this model is considered as an energy–momentum ...

Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Constraining primordial black holes as dark matter using AMS-02 data
European Physical Journal C: Particles and FieldsPrimordial black holes (PBHs) are the plausible candidates for the cosmological dark matter. Theoretically, PBHs with masses $$M_{\textrm{PBH}}$$ M PBH in the range of $$4\times 10^{14}\sim 10^{17}\,\textrm{g}$$ 4 × 10 14 ∼ 10 17 g can emit sub-GeV ...

Evidence for dynamical dark energy with an evolving Hubble constant
Astronomy & AstrophysicsContext. Hubble constant tension, together with the recent indications of dynamical dark energy proposed from the Dark Energy Spectroscopic Instrument (DESI) baryon acoustic oscillation (BAO) measurements, poses significant challenges for the standard ...
