Designing a space-based galaxy redshift survey to probe dark energy [PDF]

, 2010
A space-based galaxy redshift survey would have enormous power in constraining dark energy and testing general relativity, provided that its parameters are suitably optimized.

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.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

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

Forecasting dark showers at Belle II

Journal of High Energy Physics, 2022
Dark showers from strongly interacting dark sectors that confine at the GeV scale can give rise to novel signatures at e + e − colliders. In this work, we study the sensitivity of B factory experiments to dark showers produced through an effective ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

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.

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.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.
