Spontaneous electro-weak symmetry breaking and cold dark matter

open access: yes, 2006
In the standard model, the weak gauge bosons and fermions obtain mass after spontaneous electro-weak symmetry breaking, which is realized through one fundamental scalar field, namely Higgs field.

A Lambda CDM bounce scenario [PDF]

open access: yes, 2015
We study a contracting universe composed of cold dark matter and radiation, and with a positive cosmological constant. As is well known from standard cosmological perturbation theory, under the assumption of initial quantum vacuum fluctuations the ...

Characterizing epithelial‐mesenchymal transition‐linked heterogeneity in breast cancer circulating tumor cells at a single‐cell level

open access: yesMolecular Oncology, EarlyView.
In over 50% of non‐metastatic breast cancer patients, circulating tumor cells (CTCs) along the whole epithelial‐mesenchymal transition spectrum are detected. Total CTC number and individual phenotypes relate to aggressive disease characteristics, including lymph node involvement and higher tumor proliferation. At the single‐cell level, mesenchymal CTCs

Electroweak loop contributions to the direct detection of wino dark matter

open access: yesEuropean Physical Journal C: Particles and Fields
Electroweak loop corrections to the matrix elements for the spin-independent scattering of cold dark matter particles on nuclei are generally small, typically below the uncertainty in the local density of cold dark matter. However, as shown in this paper,

Remnants of Galactic Subhalos and Their Impact on Indirect Dark-Matter Searches

open access: yesGalaxies, 2019
Dark-matter subhalos, predicted in large numbers in the cold-dark-matter scenario, should have an impact on dark-matter-particle searches. Recent results show that tidal disruption of these objects in computer simulations is overefficient due to ...

How warm are non-thermal relics? Lyman-α bounds on out-of-equilibrium dark matter [PDF]

open access: yes, 2020
We investigate the power spectrum of Non-Cold Dark Matter (NCDM) produced in a state out of thermal equilibrium. We consider dark matter production from the decay of scalar condensates (inflaton, moduli), the decay of thermalized and non-thermalized ...

Cosmological implications of a Dark Matter self-interaction energy density

open access: yes, 2010
We investigate cosmological constraints on an energy density contribution of elastic dark matter self-interactions characterized by the mass of the exchange particle and coupling constant.

Ro 31‐8220 suppresses bladder cancer progression via enhancing autophagy in vitro and in vivo

open access: yesFEBS Open Bio, EarlyView.
The pan‐protein kinase C inhibitor Ro‐31‐8220 demonstrates potent anti‐bladder cancer effects both in vitro and in vivo by suppressing migration/invasion, inducing apoptosis and crucially activating autophagy, where blocking autophagy with chloroquine reduces its cell‐killing efficacy, suggesting its promise as a novel therapeutic candidate requiring ...
