One Hundred Years of the German Soil Science Society (DBG) 1926–2026: Origins, Facts, and Background of an Eventful History

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...

A catastrophic approach to designing interacting hysterons

New Journal of Physics
We present a framework for analyzing collections of interacting hysterons through the lens of catastrophe theory. By modeling hysteron dynamics as a gradient system, we show how to construct hysteron transition graphs by characterizing the fold ...

Study on the Vertical Stability of Drilling Wellbore under Optimized Constraints

Applied Sciences
With the development of coal resource extraction and wellbore construction proceeding towards deeper depths, the stability of drilling wellbore structures has become increasingly severe, even posing a barrier to the use of drilling method technology in ...

Study on the Slope Stability Based on Catastrophe Theory

, 2011
Based on the Drucker-Prager yield criterion which matches with the Mohr-Coulomb yield criterion under the plane strain condition, this paper sets up a cusp catastrophe model of maximum horizontal and vertical displacements to strength reduction factor by

Plasma‐activated water processing and storage time impacts pea microgreens yield and quality

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plasma‐activated water (PAW) is emerging as a sustainable input capable of enhancing crop yield and quality while reducing dependence on synthetic fertilizers. However, how PAW chemistry evolves during storage and how these dynamics translate into crop growth and quality remain poorly understood.

Spatial Patterns, Driving Forces, and Potential Grain Losses of Non‐Grain Production of Farmland in Central Yunnan Urban Agglomeration, China

Land Degradation &Development, EarlyView.
ABSTRACT The expansion of farmland non‐grain production (NGP) poses a potential threat to food security and agricultural land protection, particularly in mountainous urban agglomerations. However, the utilization patterns, driving mechanisms, and associated production‐loss effects of farmland NGP in this specific regional context remain insufficiently ...

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

Oikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.

Use of Catastrophe Theory to Establish Safety Assessment Model for Timber-Framed Heritage Buildings

BioResources
Catastrophe theory was used to establish a safety assessment model to reduce the reliance on subjective judgments in evaluation of timber-framed heritage buildings. This study was conducted in three phases.
