QED and QCD self-energy corrections through the loop-tree duality

open access: yes, 2017
The loop-tree duality (LTD) theorem establishes that loop contributions to scattering amplitudes can be computed through dual integrals, which are build from single cuts of the virtual diagrams.

Plant‐Derived Treatments for Monogenean Parasites in Farmed Fish: A Systematic Review and Meta‐Analysis

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Monogeneans are among the most problematic ectoparasites in finfish aquaculture. Plant‐derived compounds have been widely explored as therapeutic agents, yet their efficacy and safety have not been quantitatively synthesized across studies. This study provides a meta‐analysis of plant‐based treatments against monogeneans, integrating 453 in ...

Development of species distribution models helps identify source country anomalies in timber supply chains

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract For many timber species, a lack of consistent, comprehensive global distribution data makes validating supply source (country of harvest) difficult. To supplement these data, we developed species distribution models (SDMs) for the American mahogany species (genus Swietenia) to demonstrate how SDMs can assist in the analysis of supply sources ...

Body Weight Changes and Associated Social Factors in Newly Recruited Students at a Mexican Public University

open access: yesObesity Science &Practice, Volume 12, Issue 2, April 2026.
ABSTRACT Introduction The transition from high school to college involves lifestyle changes that can lead to increased body weight, a phenomenon commonly referred to as the Freshman 15. Although educational settings may differ across countries, this period could also present a risk of weight gain.

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Higher Dimensional Cosmology: Relations among the radii of two homogeneous spaces

open access: yes, 2011
We study a cosmological model in 1+D+d dimensions where D dimensions are associated with the usual Friedman-Robertson-Walker type metric with radio a(t) and d dimensions corresponds to an additional homogeneous space with radio b(t).
