On some knot energies involving Menger curvature

, 2013
We investigate knot-theoretic properties of geometrically defined curvature energies such as integral Menger curvature. Elementary radii-functions, such as the circumradius of three points, generate a family of knot energies guaranteeing self-avoidance ...

From Mechanisms to Materials: Oximate Reactivity and Emerging Strategies for Organophosphate Detoxification

ChemPhysChem, Volume 27, Issue 7, 14 April 2026.
The development of effective strategies for the detoxification of organophosphorus (OP) nerve agents has evolved from the early mechanistic studies of François Terrier and collaborators, who first elucidated the exceptional nucleophilicity of α‐effect species such as oximes and hydroxamates, to the modern design of supramolecular and material‐based ...

Effects of tree diversity and mycorrhizal type on the spatio‐temporal variability of leaf litter production and quality in temperate forests

Journal of Ecology, Volume 114, Issue 4, April 2026.
This study tested whether combining high tree species richness with mixed mycorrhizal types (arbuscular mycorrhizal [AM] and ectomycorrhizal [EM] fungi) enhances productivity in forest ecosystems. Results did not support this: neither litter production nor nutrient traits benefited from mycorrhizal mixing.

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, Volume 168, Issue 2, Page 571-587, April 2026.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Pollution Permits and Financing Costs

Journal of Money, Credit and Banking, Volume 58, Issue 3, Page 637-679, April 2026.
Abstract Effective environmental policy should consider how the financiers of polluting firms behave. We study phase III of the EU Emission Trading System. Loan spreads for cap‐and‐trade participants are a function of compliance costs, permit market features, and firms’ strategic actions.

Digitalisation of International Trade in Intellectual Properties: An Approach Based on the Utility Theory of Technology Value

The World Economy, Volume 49, Issue 4, Page 852-866, April 2026.
ABSTRACT In the era of globalisation and digital transformation, international trade has expanded beyond traditional goods and services to include the exchange of intellectual properties (IPs), particularly technology. As intangible assets become key drivers of global economic growth, accurately valuing them remains a complex challenge due to their ...

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, Volume 2026, Issue 3, March 2026.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Effect of Subphase Ions on Multilayer Deposition of an Anionic Gemini Surfactant on Solid Substrates

Journal of Surfactants and Detergents, Volume 29, Issue 2, Page 221-231, March 2026.
Multilayer formation in Gemini surfactant films with subphase ions. ABSTRACT A recently reported anionic Gemini surfactant belonging to the “minimal linker” family has been shown to form closely packed crystalline monolayers at the air–water interface, like a simple fatty acid, but its ability to deposit onto solid substrates as multilayer films ...
