Saxion cosmology for thermalized gravitino dark matter
Journal of High Energy Physics, 2017 In all supersymmetric theories, gravitinos, with mass suppressed by the Planck scale, are an obvious candidate for dark matter; but if gravitinos ever reached thermal equilibrium, such dark matter is apparently either too abundant or too hot, and is ...

Physics Letters B, 2014 We propose an ultraviolet complete theory for cold dark matter (CDM) and sterile neutrinos that can accommodate both cosmological data and neutrino oscillation experiments within 1σ level.

TeV Scale Theory for Cold and Hot Dark Matter [PDF]
Physical Review Letters, 1994 We show that an extension of the minimal supersymmetric standard model where neutrino mass arises from the spontaneous breakdown of global [ital B][minus][ital L] symmetry, can provide a scenario for both cold (CDM) and hot dark matter (HDM) where (i) both the CDM (which in our case is the superpartner of the Majoron) and the HDM (which is the massive ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Axionic hot dark matter in the hadronic axion window [PDF]
Physics Letters B, 1998 12 pages, 1 figure, LaTeX2e, epsf.sty. Discussions on Moriyama's proposal to detect solar axions without relying on axion-photon-photon coupling and Haxton-Lee bound on axion-nucleon coupling are added.

Neutrino interactions in the late universe
Journal of High Energy Physics, 2021 The cosmic neutrino background is both a dramatic prediction of the hot Big Bang and a compelling target for current and future observations. The impact of relativistic neutrinos in the early universe has been observed at high significance in a number of

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

MagmaFlow: A desktop platform for artificial intelligence‐driven expression analysis
FEBS Open Bio, EarlyView.MagmaFlow is a free, no‐code platform for gene expression analysis. It generates interactive volcano plots, links genes to literature, pathways, and diseases, prioritizes candidates using millions of publications, identifies affected biological processes, builds network diagrams, and exports publication‐ready figures and reports for macOS and Windows ...

Astronomical Signatures of Dark Matter
Advances in High Energy Physics, 2014 Several independent astronomical observations in different wavelength bands reveal the existence of much larger quantities of matter than what we would deduce from assuming a solar mass to light ratio. They are very high velocities of individual galaxies
