Global beef production: Trends, challenges, and opportunities for sustainable development

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Sustainable livestock systems require managing trade‐offs and synergies across productive, socioeconomic, and environmental dimensions to meet rising global beef demand. We present a biophysical framework to analyze how management‐driven energy allocation is manifested through herd size and total and per‐head beef productivity.

The Making of the Right to Food: Tracing Food Policy Conflict and Negotiated Outcomes in Colombia

open access: yesWorld Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT The 2016 Peace Agreement between the Colombian Government and the FARC guerrilla group marked a historic step toward ending more than five decades of armed conflict. It also reshaped national food policy with lasting implications. During the negotiations, deep ideological divisions emerged between food sovereignty and food security, and these ...

Blind Estimation Versus Direct Measurement of the Arterial Input Function in Dynamic Contrast‐Enhanced MRI of the Breast

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1947-1955, October 2026.
PurposeAccurate arterial input functions (AIFs) are essential for quantitative dynamic contrast‐enhanced (DCE) MRI, yet direct measurement is challenging and population‐averaged AIFs neglect patient‐specific variability. Blind deconvolution provides an alternative by estimating patient‐specific AIFs directly from tissue data, up to a scale factor. This

Effect of Humidity on Ionisation and Ion Chemistry in Active‐Capillary Dielectric Barrier Discharge Ionisation

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Dielectric barrier discharge ionisation (DBDI) in an active‐capillary configuration (including the commercial SICRIT source) is widely used as a soft, ambient‐pressure ionisation method for vapours and gases, yet the role of water vapour in controlling reagent ion chemistry and analytical behaviour has not been mechanistically ...

Orientations of Graphs With at Most One Directed Path Between Every Pair of Vertices

open access: yesJournal of Graph Theory, Volume 113, Issue 1, Page 143-164, September 2026.
ABSTRACT Given a graph G, we say that an orientation D of G is a KT orientation if, for all u , v ∈ V ( D ), there is at most one directed path (in any direction) between u and v. Graphs that admit such orientations have been used to construct graphs with large chromatic number and small clique number that served as counterexamples to various ...
