COZMIC. II. Cosmological Zoom-in Simulations with Fractional non-CDM Initial Conditions

open access: yesThe Astrophysical Journal
We present 24 cosmological dark matter (DM)-only zoom-in simulations of a Milky Way analog with initial conditions appropriate for scenarios where non-cold dark matter (NCDM) is a fraction of the total DM abundance (f-NCDM models) as the second ...

Growth Hormone‐Loaded 3D Printed Silk Fibroin‐Cellulose Dressings for Ischemic Wounds

open access: yesAdvanced Healthcare Materials, EarlyView.
3D‐printed wound dressings combining carboxymethyl cellulose, silk fibroin, and growth hormone accelerate healing in diabetic ulcers. These bioactive, customizable dressings enhance angiogenesis, cellular proliferation, and immune modulation. Proteomic analysis reveals activation of regenerative pathways and reduced fibrosis, highlighting their ...

Coupled Quintessence Inspired by Warm Inflation

open access: yesUniverse
We investigate a coupled quintessence cosmological model in which a dark-energy scalar field with an exponential potential interacts directly with a dark-matter fluid through a dissipative term inspired by warm inflation.

Sterile neutrino dark matter in left-right theories

open access: yesJournal of High Energy Physics, 2020
SU(2) L × SU(2) R gauge symmetry requires three right-handed neutrinos (N i ), one of which, N 1, can be sufficiently stable to be dark matter. In the early universe, W R exchange with the Standard Model thermal bath keeps the right-handed neutrinos in ...

Free streaming in warm wave dark matter [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics
We provide a framework for numerically computing the effects of free-streaming in scalar fields produced after inflation. First, we provide a detailed prescription for setting up initial conditions in the field. This prescription allows us to specify the

Injectable Deep Eutectic Solvent‐Based Ionic Gel With Rapid Gelation and Broad Hemostatic Functionality

open access: yesAdvanced Healthcare Materials, EarlyView.
An injectable deep eutectic solvent‐based ionic gel is developed for rapid in situ gelation and broad‐spectrum hemostatic functionality. The material combines high mechanical strength, strong tissue adhesion, and antibacterial activity, demonstrating potential as an advanced biofunctional gel for emergency bleeding control and wound care.

Biomimetic Fibrinogen Nanofiber Scaffolds for Vascular Hematopoietic Stem Cell Niche Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an advanced in vitro model of the vascular hematopoietic stem cell niche using self‐assembled fibrinogen nanofibers, mimicking the basement membrane in bone marrow (BM) sinusoids. The model supports the coculture of microvascular endothelial cells, stromal cells, and hematopoietic stem and progenitor cells, providing insights into ...

Synthetic Cell‐Based Tissues for Bottom‐Up Assembly of Artificial Lymphatic Organs

open access: yesAdvanced Healthcare Materials, EarlyView.
Synthetic cells have emerged as a novel biomimetic approach for fundamental research and therapeutic interventions. T cell activating synthetic cells are able to form 3D tissue‐like structures by self‐assembly into lymphatic bottom‐up tissues (lymphBUT) with tunable biochemical and biomechanical functionalities as well as metabolic activity are ...

Primordial universe with the running cosmological constant

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Theoretically, the running of the cosmological constant in the IR region is not ruled out. On the other hand, from the QFT viewpoint, the energy released due to the variation of the cosmological constant in the late Universe cannot go to the matter ...
