Physical and chemical characterization of recycled glass sand for environmental restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction We rely on coastal resources for food, water, and energy. However, over 75% of U.S. coastlines are eroding. Concurrently, the U.S. recycles less glass than other developed countries, landfilling hundreds of millions of tons every year.

Beyond Groups? Consociational Culture and the Representation of Cross‐Segmental Interests

open access: yesSwiss Political Science Review, EarlyView.
Abstract In deeply divided societies, consociational power‐sharing ensures representation for ethnonational groups but raises questions about cross‐segmental interests. This paper explores “consociational culture,” arguing that consociational systems create a form of political culture which incentivises the use of group‐based categories and identities ...

High‐Resolution LC–MS/MS Characterization of Budmunchiamine‐Type Alkaloids in Albizia niopoides

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Budmunchiamines are macrocyclic spermine alkaloids that constitute a distinctive class of polyamine natural products predominantly found in species of the genus Albizia. Comprehensive characterization of these compounds remains challenging because of their structural diversity and the limited availability of reference standards. This

A Coarse Geometric Approach to Graph Layout Problems

open access: yesJournal of Graph Theory, Volume 113, Issue 2, Page 169-194, October 2026.
ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...
