Nonadiabatic corrections to rovibrational levels of H$_2$ [PDF]

open access: yes, 2009
The leading nonadiabatic corrections to rovibrational levels of a diatomic molecule are expressed in terms of three functions of internuclear distance: corrections to the adiabatic potential, the effective nuclear mass, and the effective moment of ...

Charming penguins in B => K* pi, K (rho,omega,phi) decays

open access: yes, 2003
We evaluate the decays B => K* pi, K (rho,omega,phi) adding the long distance charming penguin contributions to the short distance: Tree+Penguin amplitudes.

Working effectively with long-distance mentors,

open access: yesInternational Journal of Women's Dermatology, 2020
Abstract Most physicians have multiple mentors and technology has facilitated long distance mentoring which can provide a different perspective from workplace mentoring. This article discusses the value and inherent challenges in a long distance mentoring relationship and tips for success.

Estimating effective survey duration in camera trap distance sampling surveys

open access: yesEcology and Evolution, 2023
Among other approaches, camera trap distance sampling (CTDS) is used to estimate animal abundance from unmarked populations. It was formulated for videos and observation distances are measured at predetermined ‘snapshot moments’.

Limits on the low energy antinucleon-nucleus annihilations from the Heisenberg principle

open access: yes, 2000
We show that the quantum uncertainty principle puts some limits on the effectiveness of the antinucleon-nucleus annihilation at very low energies. This is caused by the fact that the realization a very effective short-distance reaction process implies ...

Long-Distance Effects of Insertional Mutagenesis

open access: yesPLoS ONE, 2011
Most common systems of genetic engineering of mammalian cells are associated with insertional mutagenesis of the modified cells. Insertional mutagenesis is also a popular approach to generate random alterations for gene discovery projects. A better understanding of the interaction of the structural elements within an insertional mutagen and the ability

Adaptive Psychological Distance: A Survival Perceived Temporal Distance Effect [PDF]

open access: yesEvolutionary Psychology, 2020
Perceived temporal distance is explored using an evolutionary-functionalist perspective. Participants imagine themselves in one of three future scenarios: a survival scenario, a high-effort scenario, and a low-effort scenario. After imagining themselves in a future scenario, participants make a judgment of perceived temporal distance.

Case Study of Cost-Effective Electrification of Long-Distance Line-Haul Trucks

open access: yesEnergies, 2023
This paper investigates the economic consequences of a haulage company replacing its line-haul diesel trucks with battery-electric ones. It also examines how large truck batteries should be, whether the haulage companies should use public fast chargers ...

Nonlocal Effective Field Equations for Quantum Cosmology [PDF]

open access: yes, 2005
The possibility that the strength of gravitational interactions might slowly increase with distance, is explored by formulating a set of effective field equations, which incorporate the gravitational, vacuum-polarization induced, running of Newton's ...

Supporting Distance Learners: Making Practice More Effective

open access: yesJournal of Open, Flexible and Distance Learning, 2020
This paper reports on a qualitative evaluation of the postgraduate courses offered by distance in one university department. The types and amount of support provided to students was evaluated and compared with Simpson’s (2008a) Proactive Motivational ...
