Comparison between variational and bilinear time finite element methods performance in nonlinear dynamical system analysis [PDF]
, 1995 The purpose of this thesis is to compare the performance of two finite element formulations when applied to nonlinear dynamic system analysis. One of these formulations is a new approach to the finite element method based on Hamilton\u27s law of varying ...

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.Abstract Agricultural systems are vulnerable to extreme weather, market volatility, and changing socio‐cultural contexts. Despite efforts to create transformational solutions in agriculture to ensure economic, social, and environmental sustainability, there is often a disconnect between research findings and real‐world experience.

Diversity Snapshots: Intermodal Analysis of Firm Diversity Discourse
Intelligent Systems in Accounting, Finance and Management, Volume 33, Issue 2, June 2026.ABSTRACT Pictures are a powerful medium to communicate complex and emotive messages. In particular, the human face expresses corporate culture including diversity and equal opportunity. However, despite the recent visual turn in accounting and finance, quantitative research on diversity in photos is scant because automated solutions for identifying and

Energy‐Associated Splitting Schemes for Closed Nonlinear Port‐Hamiltonian Systems
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT We present splitting methods for port‐Hamiltonian (pH) systems, focusing on the preservation of their internal structure, in particular, the dissipation inequality. Classical high‐order splitting schemes possess negative step sizes, which might cause instabilities and the violation of the dissipation inequality.

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.The excited‐state intramolecular proton transfer (ESIPT) photoswitch tpmSA, which features an oxygen−acceptor, exhibits higher photochromic contrast (ΔE*Lab>74) than its nitrogen‐acceptor Schiff base analogues (ΔE*Lab<30). Theoretical calculations indicate that tpmSA effectively suppresses GSIPT, thereby enhancing the contrast.

British Journal of Educational Psychology, Volume 96, Issue 2, Page 875-895, June 2026.Abstract Background Many words have multiple meanings, which present challenges to learning, yet research has yet to identify effective interventions for homonyms. Lexical inference may be a promising strategy. Aim To evaluate a brief, novel lexical inference intervention for homonyms. Samples Children aged 7–8 years (Study 1: N = 180, Study 2: N = 76).
