Simple cosmological model with inflation and late times acceleration
European Physical Journal C: Particles and Fields, 2018 In the framework of polynomial Palatini cosmology, we investigate a simple cosmological homogeneous and isotropic model with matter in the Einstein frame.

Double Helical Plasmonic Antennas
Advanced Functional Materials, EarlyView.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Ultraviolet running constraints on low mass dark sectors
Journal of High Energy PhysicsWe analyze the UV breakdown of Sub-GeV dark matter models that live in a new, dark U(1) sector. Many of these models include a scalar field, which is either the dark matter itself or a dark Higgs field that generates mass terms for the dark matter ...

Advanced Functional Materials, EarlyView.FeDSNP‐Pa, a metallized nanoparticle loaded with sodium pyruvate (Pa), exerts triple therapeutic effects by scavenging reactive oxygen species (ROS), suppressing inflammatory responses, and inhibiting pyroptosis signaling pathways. This multifunctional neuroprotective strategy protecting retinal ganglion cells (RGCs) from elevated intraocular pressure ...

Acoustic misalignment mechanism for axion dark matter
Journal of High Energy PhysicsA rotation in the field space of a complex scalar field corresponds to a Bose-Einstein condensation of U(1) charges. We point out that fluctuations in this rotating condensate exhibit sound-wave modes, which can be excited by cosmic perturbations and ...

Advanced Functional Materials, EarlyView.This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...

Unifying dark energy and dark matter with a scalar field [PDF]
EAS Publications Series, 2006 The standard model of cosmology considers the existence of two components of unknown nature, ``dark matter'' and ``dark energy'', which determine the cosmological evolution. Their nature remains unknown, and other models can also be considered. In particular, it may be possible to reinterpret the recent cosmological observations so that the Universe ...
