Scale‐dependent assembly shapes taxon‐dependent responses of soil microbes to island isolation and area

Ecography, EarlyView.
The theory of island biogeography (TIB) remains contentious for microbes, as their immense dispersal potential and microscopic size may decouple diversity from classic isolation/area effects. We explicitly tested TIB scaling rules for soil bacteria and fungi across 20 oceanic islands using a rigorous multi‐scale framework that integrated high ...

How to Break Through the Ceiling of Scientific Progress?—Innovation Challenges and Pathways Based on the Fitness Landscape Framework

Exploration, EarlyView.
Science has not hit an absolute ceiling; it is stranded on a local peak. Viewed through Wright's fitness landscape, today's evaluation and funding systems over‐select, refining work within established paradigms while suppressing the drift and recombination needed to cross fitness valleys.

Impacting Fuelling Dynamics Towards Tunable Liquid Metal Machine

Exploration, EarlyView.
Confining liquid metal machines (LMMs) within one‐dimensional semi‐open channels reveals sustained, tuneable reciprocating dynamics, driven by fuel region evolution and boundary interactions. This work elucidates how spatial confinement and obstacle materials regulate symmetry‐breaking and directional control, enabling predictable LMM operation and ...

Bio‐inspired vision: From principle, material architectures to system‐level integration

FlexMat, EarlyView.
This review introduces the development and mechanism of electronic and ionic bio‐inspired vision devices respectively. Then, it explores the impact of structure on bio‐inspired visual performance from the scale of intrinsic materials and device. Finally, it concludes that only by combining advanced software and technology can more complex vision ...

Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

Food Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

Two Two‐Tier Stochastic Frontier Replications

Journal of Applied Econometrics, EarlyView.
ABSTRACT We replicate the two foundational studies which proposed the two‐tier stochastic frontier model, first in the cross‐sectional setting and then for the fixed effects panel data model. We explore matters of software then and now, different mathematical formulations of the likelihood, and alternative current software tools.

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Economic approaches to measuring labor exploitation in agriculture: A systematic literature review of indicators and methodologies

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Agriculture remains highly vulnerable to labor exploitation, affecting almost two million workers worldwide and drawing increasing attention, particularly within the framework of Sustainable Development Goal 8 of the United Nations 2030 Agenda. However, the informal nature of exploitation and fragmented data complicate its analysis.
