Force and puddling characteristics of the tilling wheel of float-assisted tillers at different lug angle and shaft speed

, 2014
Rice farmers in the Philippines generally use the water buffalo (carabao) or two-wheel tractor (walking-type) for tillage operations. An alternative is the use of float-assisted tillers. The float-assisted tiller consists of a front-mounted tilling wheel

Responsible agrivoltaics in temperate Europe: Making systems work for plants, people, and climate

PLANTS, PEOPLE, PLANET, EarlyView.
Conceptual framework illustrating the three conditions for responsible AV in temperate regions: sustained plant productivity across rotations, preservation of soil and hydrological integrity, and social license for landscape integration. Multi‐site European evidence highlights how design choices shape trade‐offs among these dimensions.

A novel high‐throughput digital morphological phenotyping method for evaluating growth traits in rice

Plant Phenome Journal
High‐throughput and noninvasive phenotyping methods are promising technology for improving efficiency in plant research and breeding. In this study, we evaluated the performance of a digital phenotyping system (DPS) based on three‐dimensional (3D) model ...

Carbon sequestration strategies for climate resilience: Sorghum‐based innovations for sustainable agriculture in dryland regions

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is intensifying heat, drought, and food insecurity, threatening dryland farming and carbon management worldwide. We reviewed research on sorghum, a drought‐adapted C4 crop, covering physiology, roots, biomass allocation, soil carbon, bioenergy, breeding, phenotyping, management, and policy.

Impulsive Thruster Control for Spacecraft Docking: A Lyapunov Approach

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this work, we propose a novel discontinuous impulsive controller for nonlinear systems that admit continuous‐time stabilizing controllers. Specifically, we develop a technique for generating discrete control pulses of short duration based on the Lyapunov candidate function associated with a continuous‐time controller. Our method uses a real‐

Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

Small Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

Toward Silica‐Free Compliance: A Low‐Viscosity Sample Pretreatment Methodology for Crystalline Quartz Quantification in Viscous Pastes

X-Ray Spectrometry, EarlyView.
ABSTRACT Crystalline quartz, the most common crystalline silica polymorph, is widely found in industrial products. It is of high regulatory relevance, because its fine fraction, a form of respirable crystalline silica, is classified as an occupational carcinogen, with product‐content thresholds (e.g., 0.1% (w/w) in the European Union) and stringent ...

Saline versus alkaline stresses in paddy soils drive divergent microbial nutrient limitations despite shared carbon constraints

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil salinization and alkalization often suppress microbial functional activity, triggering negative feedback loops in microbial metabolism, degrading nutrients and agricultural productivity.
