Architected Load Paths Enable Stiffening and Motion Programming in Soft Pneumatic Actuators

open access: yesAdvanced Science, EarlyView.
A single MARS template introduces an architected reinforcement strategy for programmable soft pneumatic actuators through internal structural organization and selective beam removal. This monolithic architecture enables deformation reconfiguration from continuous bending to joint‐like articulation and torsional motion, allowing one compliant platform ...

Environmental response to Lateglacial climate change. Reconstructions of temperature and vegetation changes in northwest Europe [PDF]

open access: yes, 2012
The Weichselian Lateglacial (~14.7-11.7 ka BP) is marked by major climatic and environmental changes in the North Atlantic region. The long-term warming trend arising during the Lateglacial was interrupted by a number of rapid climate oscillations ...

Vine‐Inspired Soft Robotics: Materials, Actuations, and Emerging Applications

open access: yesAdvanced Science, EarlyView.
Vine‐inspired robots grow from the tip, enabling navigation through confined spaces with minimal disturbance. This Review summarizes material and actuation strategies for vine‐inspired growth, key functions including steering, retraction, attachment, branching, and variable stiffness, and emerging applications spanning medical intervention, confined ...

Clouds form preferentially over native vegetation [PDF]

open access: yes, 2002
The replacement of native vegetation for agriculture leads to significant changes in land surface characteristics, such as albedo, surface roughness and canopy resistance. These land surface changes induce changes in the atmospheric boundary layer. It is

Prolonged Storage of Bound Organic Carbon in Wetland but Not Upland Soils: A 13C and 14C Perspective

open access: yesGeophysical Research Letters
Protection by metal (hydr) oxides is one of the key mechanisms for the long‐term stabilization of soil organic carbon (SOC). However, the source and turnover of (metal‐) bound organic carbon (OC) in soils are poorly constrained. Here we present the first

Rhizodeposition Drives One Third of Belowground Carbon Input in Agroecosystems

open access: yesAdvanced Science, EarlyView.
This study quantifies photosynthesized C allocation in the plant–soil system across six crop types: barley, wheat, maize, rice, legumes and grasses. It reports C partitioning into shoot respiration, shoot‐C, root‐C, net rhizodeposition and root‐derived CO2, providing standardized percentage averages and GPP‐derived absolute values as a robust baseline ...

Complementary or Competitive? Emerging Interactions Between Restoration and Protection in the Conservation Reserve Program

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The USDA's Conservation Reserve Program (CRP) delivers environmental benefits to society by enrolling cropland and grasslands to reestablish or safeguard long‐term vegetative cover. In recent years, the CRP has dramatically increased grassland enrollment while cropland enrollment has been in steady decline. This paper uses descriptive analysis,
