Asphalted parking lots are environmental filters for multiple propagule dispersal and pollination strategies

Nordic Journal of Botany, EarlyView.
Understanding community assembly for wild species in anthropogenic settings has become increasingly important as biodiversity and ecosystem services are threatened by development pressures. Urban hardscape habitats such as parking lots are widespread, extreme, terrestrial anthropogenic environments that influence plant community assembly by way of ...

Rare four-leptonic B-decays with light leptons in the final state in the Standard Model

EPJ Web of Conferences, 2017
We present predictions for the four-leptonic decays of B−-mesons with three light charged leptons and one neutrino in the final states. We obtain the branching ratio for B − → μ + μ − e − v ¯ e decay at the level 1.3 × 10−7 taking into

Scattering of Goldstone bosons and resonance production in a composite Higgs model on the lattice

Journal of High Energy Physics, 2021
We calculate the coupling between a vector resonance and two Goldstone bosons in SU(2) gauge theory with N f = 2 Dirac fermions in the fundamental representation. The considered theory can be used to construct a minimal Composite Higgs models.

Vector meson pole dominance in decays into mesons

Physics Letters B, 1979
Abstract The validity of the assumption that J ψ decays into mesons proceed via ω, φ and ϱ0 poles followed by cascade decays is examined. Λ( J ψ → B π) is well reproduced by using Λ( J ψ → ϱπ), Λ(ω → ϱπ), Λ( B → ωπ) and the B → ωπ helicity structure. The structure of OZI-violating J ψ − V 0 transitions

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

A dimension five Lorentz-violating nonminimal coupling for mesons in the KLZ model

Nuclear Physics B, 2019
We investigate a dimension five Lorentz-violating (LV) nonminimal coupling between the neutral vector meson field strength and the pion current in the context of the Kroll-Lee-Zumino (KLZ) model. In this modified model we study the vector meson dominance

On the transition form factors of the axial-vector resonance f 1(1285) and its decay into e + e −

Journal of High Energy Physics, 2021
Estimating the contribution from axial-vector intermediate states to hadronic light-by-light scattering requires input on their transition form factors (TFFs).

Biological Flora of Britain and Ireland: Geranium sylvaticum*

Journal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.

Measurement of the e+e−→ ηπ+π− cross section with the CMD-3 detector at the VEPP-2000 collider

Journal of High Energy Physics, 2020
The cross section of the process e+e−→ ηπ+π− is measured using the data collected with the CMD-3 detector at the VEPP-2000 collider in the center-of-mass energy range from 1.1 to 2.0 GeV.

An integrated social–ecological–evolutionary–phenotypic (SEEP) approach to understanding animal responses to urbanization

Biological Reviews, Volume 101, Issue 1, Page 419-436, February 2026.
ABSTRACT Humans play key roles in shaping the structure and processes of ecosystems globally, especially in cities. This recognition has prompted a recent focus on understanding urban systems via interactions between human social systems and ecological and evolutionary processes.
