Calculations of the polycentric linear molecule H32+ with the finite element method [PDF]

open access: yesChemical Physics Letters, 1993
Abstract A fully numerical two-dimensional solution of the Schrodinger equation is presented for the linear polyatomic molecule H 3 2+ using the finite element method (FEM). The Coulomb singularities at the nuclei are rectified by using both a condensed element distribution around the singularities and special elements.

Higher Genetic Diversity Across Several Small Patches Compared to a Single Large Patch: A Within‐Species Test of SLOSS

open access: yesEvolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT The SLOSS (Single Large or Several Small) debate is crucial in reserve design, focusing on evaluating the conservation efficacy of a single large reserve versus multiple small reserves for species preservation. While accumulating evidence suggests that multiple small reserves may conserve greater species diversity, the question of how to ...

Diabetes self‐management education and its association with hospital admissions and premature mortality: A scoping review and meta‐analysis

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 2, Page 850-864, February 2026.
Abstract Type 2 diabetes is associated with increased all‐cause hospital admissions and premature mortality. Diabetes self‐management education (DSME) is internationally recommended but its impact on reducing hospital admissions and premature mortality is unclear.

Structural and functional characterization of the newly identified Photorhabdus laumondii tumor necrosis factor‐like lectin

open access: yesThe FEBS Journal, Volume 293, Issue 4, Page 1168-1190, February 2026.
We characterize the PLTL lectin from Photorhabdus laumondii, which adopts a unique TNF‐like fold. Binding assays reveal a preference for branched histo‐blood group oligosaccharides. Protein crystallography uncovers a novel hexameric assembly and identifies key residues involved in carbohydrate recognition.

Lower trade credit payment delays as a result of exclusion from tax deductible expenses

open access: yesInternational Journal of Management and Economics
This article tests whether excluding late and long payments from deductible expenses shortens days payable outstanding (DPO). We exploit a natural experiment of increasing the income tax base resulting from liabilities overdue for more than 30 days and ...

Electronic Structure and Lattice dynamics of NaFeAs

open access: yes, 2009
The similarity of the electronic structures of NaFeAs and other Fe pnictides has been demonstrated on the basis of first-principle calculations. The global double-degeneracy of electronic bands along X-M and R-A direction indicates the instability of Fe ...

Combining ability and heterosis in partial resistance to gray leaf spot in elite maize (Zea mays L.) genotypes

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract Six sets of 48 maize (Zea mays L.) inbred lines, and their 96 single crosses generated using the North Carolina Mating Design II system, were evaluated for resistance to gray leaf spot (GLS). The aim of the study was to assess the implications of combining ability, heterotic effects, and potence ratio in breeding for GLS resistance in maize ...
