Molecular dynamics simulations of lead clusters

open access: yes, 2001
Molecular dynamics simulations of nanometer-sized lead clusters have been performed using the Lim, Ong and Ercolessi glue potential (Surf. Sci. {\bf 269/270}, 1109 (1992)).

Learning, Technology, and Technique

open access: yesCanadian Journal of Learning and Technology, 2022
To be human is to be a user, a creator, a participant, and a co-participant in a richly entangled tapestry of technologies – from computers to pedagogical methods - that make us who we are as much as our genes.

Highly Frustrated Magnetic Clusters: The kagome on a sphere [PDF]

open access: yes, 2008
We present a detailed study of the low-energy excitations of two existing finite-size realizations of the planar kagome Heisenberg antiferromagnet on the sphere, the cuboctahedron and the icosidodecahedron. After highlighting a number of special spectral

On \pi-surfaces of four-dimensional parallelohedra [PDF]

open access: yes, 2013
We show that every four-dimensional parallelohedron P satisfies a recently found condition of Garber, Gavrilyuk & Magazinov sufficient for the Voronoi conjecture being true for P. Namely we show that for every four-dimensional parallelohedron P the group

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

Enhancing the drug ontology with semantically-rich representations of National Drug Codes and RxNorm unique concept identifiers

open access: yesBMC Bioinformatics, 2019
Background The Drug Ontology (DrOn) is a modular, extensible ontology of drug products, their ingredients, and their biological activity created to enable comparative effectiveness and health services researchers to query National Drug Codes (NDCs) that ...

Properties of highly frustrated magnetic molecules studied by the finite-temperature Lanczos method

open access: yes, 2010
The very interesting magnetic properties of frustrated magnetic molecules are often hardly accessible due to the prohibitive size of the related Hilbert spaces.

Minimal Bending Energies of Bilayer Polyhedra [PDF]

open access: yes, 2010
Motivated by recent experiments on bilayer polyhedra composed of amphiphilic molecules, we study the elastic bending energies of bilayer vesicles forming polyhedral shapes.

The Human Nature of Generative AIs and the Technological Nature of Humanity: Implications for Education

open access: yesDigital, 2023
This paper analyzes the ways that the widespread use of generative AIs (GAIs) in education and, more broadly, in contributing to and reflecting the collective intelligence of our species, can and will change us.

Application of the finite-temperature Lanczos method for the evaluation of magnetocaloric properties of large magnetic molecules

open access: yes, 2012
We discuss the magnetocaloric properties of gadolinium containing magnetic molecules which potentially could be used for sub-Kelvin cooling. We show that a degeneracy of a singlet ground state could be advantageous in order to support adiabatic processes
