Stringy dark energy model with cold dark matter
Physics Letters B, 2005 Cosmological consequences of adding the Cold Dark Matter (CDM) to the exactly solvable stringy Dark Energy (DE) model are investigated. The model is motivated by the consideration of our Universe as a slowly decaying D3-brane. The decay of this D-brane is described in the String Field Theory framework.

Advanced Functional Materials, EarlyView.Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Accurate Inner Stellar Density Slopes from Projected Surface Densities in Galaxies
The Astrophysical JournalThe inner slope of the three-dimensional stellar density in dwarf galaxies ( ${\rho }^{{\prime} }[0]$ ) is a sensitive probe of possible departures from the collisionless cold dark matter (CDM) paradigm, since cored stellar distributions ( ${\rho ...

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

Condensation of galactic cold dark matter
Journal of Cosmology and Astroparticle Physics, 2016 We consider the steady-state regime describing the density profile of a dark matter halo, if dark matter is treated as a Bose-Einstein condensate. We first solve the fluid equation for "canonical" cold dark matter, obtaining a class of density profiles which includes the Navarro-Frenk-White profile, and which diverge at the halo core.

Advanced Functional Materials, EarlyView.Co‐assembly of rationally designed glycosaminoglycan‐binding peptides with sulfated glycosaminoglycans yields supramolecular hydrogels with tunable mechanics and matrix‐mediated cytokine retention. The glycosaminoglycans thereby act as cofactors, driving a coil‐to‐β‐sheet transition that triggers gelation.

Self-interacting Dark Matter in the Center of a Local Group Dwarf Galaxy and Its Satellites
The Astrophysical JournalWe present a detailed comparison of a Local Group dwarf galaxy analogue evolved in two cosmological models: the standard cold dark matter (DM) and a self-interacting dark matter (SIDM) model with a velocity-dependent cross section.

Advanced Functional Materials, EarlyView.This work developed an all‐aqueous freeze‐thaw strategy to create a dual‐conductive PVA/P3KBT binder for high volume‐change lithium–ion battery anodes. The resulting binder system strengthens the electrode structure, supports ion and electron transport, and accommodates repeated volume changes, reducing cracking and improving long‐term cycling ...
