Casimir energy stabilization of Standard Model landscape in dark dimension
Journal of High Energy PhysicsIn this paper we present a realization of the dark dimension. We consider the 5D Standard Model coupling to gravity with one dimension compactified on an orbifold, which is seen as the dark dimension of size R.

Human flaws and logical tools in engineering
The Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3512-3520, August 2025.Abstract This paper explores the limitations of human cognition, especially in engineering research, emphasizing the need for mathematical models and methods to guide decision‐making and theory validation. While human cognition excels in certain tasks, it is prone to biases that can distort our understanding.

G-modes and the solar neutrino problem [PDF]
The Astrophysical Journal, 1993 We show that low-order g-modes with large enough amplitudes to affect significantly the solar neutrino fluxes would produce surface velocities that are $10^4$ times larger than the observed upper limits and hence are ruled out by existing data. We also demonstrate that any large-amplitude, short-period oscillations that grow on a Kelvin-Helmholtz time ...

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

A Broad Set of Solar and Cosmochemical Data Indicates High C-N-O Abundances for the Solar System
The Astrophysical JournalWe examine the role of refractory organics as a major C carrier in the outer protosolar nebula and its implications for the compositions of large Kuiper Belt objects (KBOs) and CI chondrites.

An Expanded Set of Los Alamos OPLIB Tables in MESA: Type-1 Rosseland-mean Opacities and Solar Models
The Astrophysical JournalWe present a set of 1194 Type-1 Rosseland-mean opacity tables for four different metallicity mixtures. These new Los Alamos OPLIB atomic radiative opacity tables are an order of magnitude larger in number than any previous opacity table release, and span

Recent Developments in Halide Perovskite Nanocrystals for Indirect X‐ray Detection
Advanced Materials Technologies, Volume 9, Issue 20, October 21, 2024.Perovskite nanocrystals act as scintillators under X‐ray illumination with different conversion yield, stability, or decay times and outperform commercial materials, depending on their composition, host matrix, and luminescence process. Besides the lead halide perovskites, there are lead‐free alternatives providing self‐trapped exciton emission ...

Four-neutrino oscillations and the solar neutrino problem [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2001 We perform a fit of solar neutrino data in the framework of the two four-neutrino schemes that are compatible with the results of all neutrino oscillation experiments. These schemes allow simultaneous transitions of solar nu_e's into active nu_mu's, nu_tau's and sterile nu_s. The data imply that the SMA solution is valid for any combination of nu_e->
