WorldCuP: A database of checklists documenting the World's Cultivated Plants and their distributions

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Human life would be unrecognizable without the benefits of cultivated plants, including crops, ornamentals, or plants with other uses. Despite their importance in daily life and prevalence across landscapes, we know surprisingly little about global cultivated plant distributions.

Equivalência entre o princípio variacional de Maupertuis, a segunda lei de Newton e a geometria conforme

open access: yesRevista Brasileira de Ensino de Física
As aplicações da geometria diferencial na física não estão restritas somente à teoria da relatividade geral. Esse artigo é dedicado a mostrar uma das diversas aplicações dos métodos geométricos a um conceito físico elementar e ao mesmo tempo profundo: a ...

Geometric Intuition Enables Resource‐Efficient Screening for β‐Barrel‐Like Folds in Viral Structural Dark Matter

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Predicted protein structures now enable fold discovery beyond the reach of sequence homology, but scalable and interpretable methods remain limited. We present Cooper‐Beta, a resource‐efficient, chain‐resolved framework for detecting β‐barrel‐like folds from strand connectivity.

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Evaluating Pose Estimation Uncertainty From Automatic Point Cloud Registration in Multi‐Sensor Robotic Systems

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The poses derived from automatic point cloud registration between stationary laser scans that occur naturally in robotic multi‐sensor systems operating in stop‐and‐go mode have the potential to greatly improve and aid localization and trajectory estimation.

Climate Crisis, Human Mobility and Security Challenges in the MENA Region: Implications for Sustainable Development and Regional Stability

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

The isospectral problem for $p$-widths: an application of Zoll metrics

open access: yesComptes Rendus. Mathématique
We pose the isospectral problem for the $p$-widths: is a Riemannian manifold $(M^{n+1}, g)$ uniquely determined by its $p$-widths, $\bigl \lbrace \omega _p(M,g)\bigr \rbrace _{p=1}^{\infty }$? We construct many counterexamples on $S^2$ using Zoll metrics

A remarkable identity for lengths of curves [PDF]

open access: yes
In this thesis we will prove the following new identity Σγ 1/(1 + exp |γ|) = 1/2, where the sum is over all closed simple geodesics γ on a punctured torus with a complete hyperbolic structure, and |γ| is the length of γ. Although it is well known

Phasing Out Coal Power Through Cross‐Border Renewable Energy Trade in the Asia‐Pacific

open access: yesSustainable Development, EarlyView.
ABSTRACT Coal remains the backbone of electricity generation in the Asia‐Pacific region, accounting for half of total regional output and two‐thirds of global coal‐fired capacity. The substantial environmental and public‐health externalities of coal highlight the urgent need to accelerate the renewable energy transition.
