BBN constraints on the annihilation of MeV-scale dark matter [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
Thermal dark matter at the MeV scale faces stringent bounds from a variety of cosmological probes. Here we perform a detailed evaluation of BBN bounds on the annihilation cross section of dark matter with a mass 1 MeV ≲ mχ ≲ 1 GeV . For p-wave suppressed

Characteristics of Late-phase >100 MeV Gamma-Ray Emission in Solar Eruptive Events [PDF]

Astrophysical Journal, 2018
We characterize and catalog 30 solar eruptive events observed by the Fermi Large Area Telescope (LAT) having late-phase >100 MeV γ-ray emission (LPGRE), identified 30 yr ago in what were called long-duration gamma-ray flares.

Elicitation of Roots and AC-DC with PEP-13 Peptide Shows Differential Defense Responses in Multi-Omics

Cells, 2022
The root extracellular trap (RET) has emerged as a specialized compartment consisting of root AC-DC and mucilage. However, the RET’s contribution to plant defense is still poorly understood.

User-friendly extraction and multistage tandem mass spectrometry based analysis of lipid-linked oligosaccharides in microalgae

Plant Methods, 2018
Background Protein N-glycosylation is initiated within the endoplasmic reticulum through the synthesis of a lipid-linked oligosaccharides (LLO) precursor.

Directly Detecting MeV-Scale Dark Matter Via Solar Reflection. [PDF]

Physical Review Letters, 2017
If dark matter (DM) particles are lighter than a few   MeV/c^{2} and can scatter off electrons, their interaction within the solar interior results in a considerable hardening of the spectrum of galactic dark matter received on Earth.

Protein N-glycosylation in eukaryotic microalgae and its impact on the production of nuclear expressed biopharmaceuticals

Frontiers in Plant Science, 2014
Microalgae are currently used for the production of food compounds. Recently, few microalgae species have been investigated as potential biofactories for the production of biopharmaceuticals.

Detection of sub-MeV dark matter with three-dimensional Dirac materials [PDF]

, 2017
We propose the use of three-dimensional Dirac materials as targets for direct detection of sub-MeV dark matter. Dirac materials are characterized by a linear dispersion for low-energy electronic excitations, with a small band gap of O(meV) if lattice ...

Crossing the Dripline to 11N Using Elastic Resonance Scattering [PDF]

, 2000
The level structure of the unbound nucleus 11N has been studied by 10C+p elastic resonance scattering in inverse geometry with the LISE3 spectrometer at GANIL, using a 10C beam with an energy of 9.0 MeV/u.

A Novel In Vitro Tool to Study Cyst Nematode Chemotaxis

Frontiers in Plant Science, 2020
This study presents a novel three-dimensional (3D) tool “3D in vitro choice” for chemotaxis assays with cyst nematodes. The original 3D in vitro choice was customized through digital printing.
