Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3738-3750, September 2026.ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

Sustainable Development, Volume 34, Issue 4, Page 4852-4865, August 2026.ABSTRACT Displacing people to make way for development projects is contentious. Empirical research demonstrates that neither human rights guidelines nor multilateral lenders' standards guarantee positive, sustainable outcomes for displaced people. With multiple new displacing projects proposed globally, including for renewable energy, we propose a new ...

From community care to corporate category: Platforms' discourse on digital trans‐affirming practices
Journal of Linguistic Anthropology, Volume 36, Issue 2, August 2026.Abstract Trans‐affirming community movements have interfaced with tech platforms in recent decades, leading to innovations in pronoun‐sharing online. As (mostly US‐based) platforms created online “pronouns fields,” they released supportive statements and help pages about the feature. However, with the recent roll‐back of LGBTQ+ support, such support is
