Pedo‐Climatic Controls on Soil Health Recovery Across Cultivation Chronosequences: Hydraulic Conductivity as a Potential Link Between Soil Structure, Microbial Biomass, and Nutrient Availability

Land Degradation &Development, EarlyView.
ABSTRACT Long‐term cultivation can improve soil health, but recovery may not follow the same pathway across contrasting soil and climate conditions. A key unresolved question is whether soil health recovery is mainly associated with the release of physical–chemical constraints or with the gradual rebuilding of carbon, microbial biomass, and nutrient ...

Comparative Effectiveness of Different Mulch Types and Application Rates for Reducing Runoff and Sediment Yield on Forest Skid Trails

Land Degradation &Development, EarlyView.
ABSTRACT Rehabilitation of skid trails following timber harvesting is critical for preserving forest soil integrity, particularly within ecologically sensitive ecosystems such as the Hyrcanian forests of northern Iran, a UNESCO World Heritage Site. Although mulching is widely recommended for erosion control, field evidence comparing different locally ...

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

Macromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.
Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

Design, Analysis, and Experimental Validation of a Variable‐Gap Magnetorheological Damper for Seat Suspension

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...
