A new recipe for $$\Lambda $$ Λ CDM
European Physical Journal C: Particles and Fields, 2017 It is well known that a canonical scalar field is able to describe either dark matter or dark energy but not both. We demonstrate that a non-canonical scalar field can describe both dark matter and dark energy within a unified setting.

Cosmological constraints on non-cold dark matter from DESI DR2 measurements
Physics Letters BWe investigate potential deviations from cold dark matter (CDM) using the latest Baryon Acoustic Oscillations (BAO) measurements from the Dark Energy Spectroscopic Instrument (DESI).

DUNE Prospect for Leptophobic Dark Matter
Advances in High Energy Physics, 2020 Highly energetic proton/electron beam fixed-target experiments extend an opportunity to probe the sub-GeV dark matter and associated interactions. In this work, we have explored the sensitivity of DUNE (Deep Underground Neutrino Experiment) for sub-GeV ...

Strangeness, cosmological cold dark matter and dark energy [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2005 It is now believed that the universe is composed of a small amount of the normal luminous matter, a substantial amount of matter (Cold Dark Matter: CDM) which is non-luminous and a large amount of smooth energy (Dark Energy: DE). Both CDM and DE seem to require ideas beyond the standard model of particle interactions.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
Molecular Oncology, EarlyView.The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Closed-form Expressions for Multiscatter Dark Matter Capture Rates
The Astrophysical JournalAny astrophysical object can, in principle, serve as a probe of the interaction between dark matter (DM) and regular baryonic matter. This method is based on the potential observable consequences annihilations of captured DM have on the surface ...

To Observe, or Not to Observe, Quantum-Coherent Dark Matter in the Milky Way, That is a Question
Frontiers in Astronomy and Space Sciences, 2021 In recent years, Bose-Einstein-condensed dark matter (BEC-DM) has become a popular alternative to standard, collisionless cold dark matter (CDM). This BEC-DM -also called scalar field dark matter (SFDM)- can suppress structure formation and thereby ...

The offsets between galaxies and their dark matter in Λ cold dark matter [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2015 Abstract We use the ‘Evolution and Assembly of GaLaxies and their Environments’ (eagle) suite of hydrodynamical cosmological simulations to measure offsets between the centres of stellar and dark matter components of galaxies. We find that the vast majority (>95 per cent) of the simulated galaxies display an offset smaller than ...

Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
