Which, when, and where traits matter: functional trait‐mediated species associations shift with microenvironmental and climatic variation

New Phytologist, Volume 251, Issue 5, Page 2468-2481, September 2026.
Community‐level fitted relationship between spatial association Lij and trait dissimilarity (tDij) at the fine spatial scale (r = 40 mm; where r represents the radius around individuals of the focal species). Summary Predicting coexistence in species‐rich plant communities requires understanding the role of functional traits in species interactions and

Higher representation stability for ordered configuration spaces

Journal of Topology, Volume 19, Issue 3, September 2026.
Abstract Using factorization homology with coefficients in twisted commutative algebras (TCAs), we prove two flavors of higher representation stability for the cohomology of (generalized) configuration spaces of a scheme/topological space X$X$. First, we provide an iterative procedure to study higher representation stability using actions coming from ...

The Development and Validation of a Simple Method for the Determination of Meropenem Concentrations in Human Plasma Using High‐Performance Liquid Chromatography

Applied Research, Volume 5, Issue 4, August 2026.
A simple, rapid, and sustainable HPLC‐UV method was developed and validated to quantify meropenem in human plasma across a wide linear range (0.5–100 mg/L). Utilizing an efficient one‐step protein precipitation, this eco‐friendly approach is highly suited for routine clinical therapeutic drug monitoring and research purposes.

Revisiting the nomenclature of Carludovica microcephala, type species of Dicranopygium (Cyclanthaceae)

TAXON, Volume 75, Issue 4, August 2026.
Abstract The name Carludovica microcephala, basionym of the type species of Dicranopygium (Cyclanthaceae), has long been attributed to J.D. Hooker (1892), based on plants cultivated at the Royal Botanic Gardens, Kew. A reassessment of nineteenth‐century horticultural literature shows that the name had already been validly published 35 years earlier, in

Partisan Entrepreneurship

The Journal of Finance, Volume 81, Issue 4, Page 1841-1892, August 2026.
ABSTRACT Republicans start more firms than Democrats. In a sample of 40 million party‐identified Americans between 2005 and 2017, we find that 5.5% of Republicans and 3.7% of Democrats become entrepreneurs. This partisan entrepreneurship gap is time‐varying—Republicans increase their relative entrepreneurship during Republican administrations and ...

Praktisk-estetisk læringsinteresse - en motkulturell verdi?

Nordisk Kulturpolitisk Tidsskrift, 2015
I denne artikkelen rettes oppmerksomheten mot kulturelle verdier som oppstår gjennom en folkelig interesse for praktisk-estetiske læringsaktiviteter. Hvordan kan de tolkes i forhold til dagens travle og oppsplittede samfunn?

Evaluating maturity of organic matter in hydrated C1 and CM‐like clasts and a dehydrated clast within a polymict eucrite and a howardite

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1965-1993, August 2026.
Abstract Volatile‐rich xenolithic clasts in different types of brecciated meteorites represent unique pristine solar system material. This study investigates the maturity and thermal history of organic matter using Raman spectroscopy and aqueous alteration effects using infrared spectroscopy in the matrix of 15 volatile‐rich clasts (C1 and CM‐like ...

Dehydration‐driven organization of metabolites into NaDES‐like assemblies in orthodox seeds

New Phytologist, Volume 251, Issue 3, Page 1172-1187, August 2026.
Summary Desiccation tolerance in plants, especially during orthodox seed dehydration, relies on compatible solute accumulation, complex molecular mechanisms, and intermolecular organizations that remain poorly understood. We combined metabolite profiling, mass spectrometry imaging, and electrospray and cold‐spray ionization mass spectrometry to ...

A trace–path integral formula over function fields

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract We show that an arithmetic path integral over the ℓ$\ell$‐torsion of a Jacobian J[ℓ]$J[\ell]$ is equal to the trace of the Frobenius action on a representation of the Heisenberg group H(J[ℓ])$H(J[\ell])$, up to an explicitly determined sign.

Recognising flag varieties and reductive groups

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract Fix a flat and projective morphism X→Σ$X\rightarrow \Sigma$ of schemes. We show, first, that any set of P1${\mathbb {P}}^1$‐fibrations on X$X$ defines a set of simple roots, a set of simple coroots and a Cartan matrix C$C$. Second, X$X$ is an étale F${\mathcal {F}}$‐bundle over some projective Σ$\Sigma$‐scheme, where F${\mathcal {F}}$ is the ...
