Inverse Seesaw, dark matter and the Hubble tension

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We consider the inverse Seesaw scenario for neutrino masses with the approximate Lepton number symmetry broken dynamically by a scalar with Lepton number two.

Challenges of the Standard Cosmological Model

open access: yesUniverse, 2022
Measurements of the temperature and polarization anisotropy of the cosmic microwave background (CMB) provided strong confirmation of the vanilla flat ΛCDM model of structure formation.

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

open access: yesInterdisciplinary Materials, Volume 5, Issue 5, Page 834-867, September 2026.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

Hubble tension and absolute constraints on the local Hubble parameter

open access: yes, 2021
It is shown, from the two independent approaches of McCrea-Milne and of Zeldovich, that one can fully recover the set equations corresponding to the relativistic equations of the expanding universe of Friedmann-Lemaitre-Robertson-Walker geometry ...

Soft quantum back reaction to the hubble tension: A smeared-out early time cosmological energy density

open access: yesPhysics Letters B
A theoretical explanation for the so-called Hubble tension is provided within the framework of phase-space quantum mechanics extended to (quantum) cosmology.

Investigating Galactic Cosmic Ray Ionization’s Contribution to Aerosol Formation on Neptune and a Potential Link to the Relationship Between Brightness and Solar Activity

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract In this work we investigate how ionization from Galactic Cosmic Rays (GCRs) can affect aerosol nucleation on Neptune and discuss potential implications for the observed brightness variations that appear to follow the solar cycle. We calculate the planetary vertical cutoff rigidity for Neptune based on the O8 ${\mathrm{O}}_{8}$ magnetic field ...

Cosmological implications of ns ≈ 1 in light of the Hubble tension

open access: yesPhysics Letters B, 2022
Recently, a low-z measurement of the Hubble constant, H0=73.04±1.04km/s/Mpc, was reported by the SH0ES Team. The long-standing Hubble tension, i.e. the difference between the Hubble constant from the local measurements and that inferred from the cosmic ...

Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

open access: yesGlobal Policy, Volume 17, Issue S4, Page S56-S67, August 2026.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

Comparison of Olive Versus Fish Oil Based Parenteral Nutrition and Clinical Outcomes—A Systematic Review

open access: yesJournal of Human Nutrition and Dietetics, Volume 39, Issue 4, August 2026.
ABSTRACT Background It is well‐established that earlier generations of lipid emulsions based on soybean oil are inferior to later generations based on olive or fish oil. However, evidence directly comparing between later‐generation lipid emulsions is limited.

Korean Red Ginseng Attenuates Dysfunctions and Modulates Inflammatory and Neuroplasticity Markers in the Harmaline‐Induced Model of Essential Tremor

open access: yesBrain and Behavior, Volume 16, Issue 6, June 2026.
Korean red Ginseng significantly reduces tremor severity, improves motor coordination, and ameliorates anxiety and cognitive deficits in a mouse model of essential tremor through suppression of neuroinflammatory markers and normalization of neuroplasticity genes in the cerebellum.
