Effects of thickness on the spin susceptibility of the 2D electron gas

open access: yes, 2004
Using available quantum Monte Carlo predictions for a strictly 2D electron gas, we have estimated the spin susceptibility of electrons in actual devices taking into account the effect of the finite transverse thickness and finding a very good agreement ...

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Computation of the electron beam quality $k_{{\rm Q,Q}_0}$ factors for the NE2571, NE2571A and NE2581A thimble ionization chambers using PENELOPE

open access: yes, 2017
The quality correction factor $k_{Q,Q_{0}}$ for electron beams was calculated for three thimble ionization chambers, namely, NE2571, NE2571A and NE2581A.

Generative Subsurface Flow Modeling With Pretrained Diffusion Model and Training‐Free Knowledge Alignment

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We introduce a versatile generative learning framework that integrates probabilistic diffusion models, observational data, and domain knowledge for stochastic modeling of flow in porous media. The framework begins by pretraining an unconditional diffusion model to approximate the joint distribution of subsurface parameters and state variables,

Three flavor neutrino oscillation analysis of atmospheric neutrinos in Super-Kamiokande

open access: yes, 2006
We report on the results of a three-flavor oscillation analysis using Super-Kamiokande~I atmospheric neutrino data, with the assumption of one mass scale dominance ($\Delta m_{12}^2$$=$0).

Excitonic condensation in a symmetric electron-hole bilayer

open access: yes, 2002
Using Diffusion Monte Carlo simulations we have investigated the ground state of a symmetric electron-hole bilayer and determined its phase diagram at T=0. We find clear evidence of an excitonic condensate, whose stability however is affected by in-layer

Measurement of Dielectric Suppression of Bremsstrahlung

open access: yes, 1995
In 1953, Ter-Mikaelian predicted that the bremsstrahlung of low energy photons in a medium is suppressed because of interactions between the produced photon and the electrons in the medium. This suppression occurs because the emission takes place over on
