Constraints to Dark Matter from Inert Higgs Doublet Model
Advances in High Energy Physics, 2016 We study the Inert Higgs Doublet Model and its inert scalar Higgs H as the only source for dark matter. It is found that three mass regions of the inert scalar Higgs can give the correct dark matter relic density.

Scalar dark matter behind b → sμμ anomaly
Journal of High Energy Physics, 2019 We construct a scalar dark matter model with U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ symmetry in which the dark matter interacts with the quark flavours, allowing lepton non-universal b → s ℓ ℓ ¯ $$ s\ell \overline{\ell} $$ decays. The

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

What laboratory experiments can teach us about cosmology: A chameleon example [PDF]
EPJ Web of Conferences, 2019 Laboratory experiments can shed light on theories of new physics introduced in order to explain cosmological mysteries, including the nature of dark energy and dark matter.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Dark matter searches and energy accumulation and release in materials
SciPost Physics Proceedings, 2023 Efforts to identify dark matter by detecting nuclear recoils produced by dark matter particles reveal low-energy backgrounds of unknown origin in different types of detectors.

FEBS Letters, EarlyView.The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Leptonic WIMP coannihilation and the current dark matter search strategy
Journal of High Energy Physics, 2018 We discuss the extent to which models of Weakly Interacting Massive Particle (WIMP) Dark Matter (DM) at and above the electroweak scale can be probed conclusively in future high energy and astroparticle physics experiments.

Identification of the plant mitochondrial OrfX protein: A mass spectrometry approach
FEBS Letters, EarlyView.The mitochondrial genome of plants contains an open reading frame, orfx, which encodes a rare protein that has so far escaped mass spectrometric detection. The protein resembles the c‐subunit of bacterial twin‐arginine‐motif‐dependent protein translocases (TatC).

Fermionic singlet dark matter in one-loop solutions to the $$R_K$$ R K anomaly: a systematic study
European Physical Journal C: Particles and Fields, 2021 We study the dark matter phenomenology of Standard Model extensions addressing the reported anomaly in the $$R_K$$ R K observable at one-loop.
