Molecular survey of vector-borne agents in lowland tapirs (Tapirus terrestris) from Brazil reveals a new Anaplasma genotype

open access: yes
Although vector-borne agents have been detected in different species of wild animals, studies involving tapirs (Tapirus terrestris), the largest land mammals in Brazil, are scarce.

Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints

open access: yesStructural Concrete, Volume 27, Issue 5, Page 8159-8179, October 2026.
Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

Multifactorial diagnosis of drought‐induced decline in Mediterranean conifer forests

open access: yesJournal of Ecology, Volume 114, Issue 10, October 2026.
A multi‐proxy approach integrating radial growth, leaf morphology, stable isotopes, elemental composition and soil properties revealed interacting mechanisms underlying drought‐induced dieback in Mediterranean pine populations. Declining trees showed stronger drought impacts on growth, altered stomatal regulation, nutrient imbalances and accelerated ...

The public agglomeration effect: Urban–rural divisions in government efficiency and political preferences

open access: yesAmerican Journal of Political Science, Volume 70, Issue 4, Page 1464-1481, October 2026.
Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of

Electrochemical Determination of the Ionization Energy and the Electron Affinity of Lead Halide Perovskite Thin Films: A Comparison to Ultraviolet Photoelectron Spectroscopy

open access: yesChemPhysChem, Volume 27, Issue 17, 14 September 2026.
Benchmarking cyclic voltammetry (CV), electrochemical voltage spectroscopy (EVS), and ultraviolet photoelectron spectroscopy (UPS), complemented by photothermal deflection spectroscopy (PDS), provides practical guidance for halide perovskite energy‐level studies. Strategies for consistent onset determination across techniques are additionally addressed.
