Double Helix Structure for Stable Flexural Actuation in Soft Robotics
Advanced Intelligent Systems, EarlyView.This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

Advanced Intelligent Systems, EarlyView.Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...

Accounting for animal health in efficiency analysis: An application to Swedish dairy farms
American Journal of Agricultural Economics, EarlyView.Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State
American Journal of Botany, EarlyView.Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

The Q-Slope Method for Rock Slope Engineering
Rock Mechanics and Rock Engineering, 2017Q-slope is an empirical rock slope engineering method for assessing the stability of excavated rock slopes in the field. Intended for use in reinforcement-free road or railway cuttings or in opencast mines, Q-slope allows geotechnical engineers to make potential adjustments to slope angles as rock mass conditions become apparent during construction ...

Stability Assessment of Rock Slope and Design of Rock Slope Reinforcement
2019The stability analysis of rock slopes has been a challenging task because of the presence of discontinuities in various forms which result in different types of slope failures. Discontinuities are the weakest zones in the rock mass. Failure mechanism of a rock slope mainly depends on the characteristics of discontinuities.

Journal of Geotechnical and Geoenvironmental Engineering, 2000
The behavioral modes to which a rock slope is susceptible are many and complex. This article discusses a long but not exhaustive list of common failure styles, highlighting observable characteristics that distinguish one from another. Slopes in both strong and weak rock masses are considered.

Summary This paper reviews some principles of rock slope monitoring and describes equipment that can be used for this purpose. In attempting a broad review of techniques it is impossible to give full details relevant to each item of equipment, or to supplement the text with case histories. This information can be found in the bibliography, in

This chapter presents stabilisation practices for rock slopes. Stabilisation processes can be divided into two groups: 1. Techniques which attempt to fix loose blocks in place by rock anchoring or bolting to avoid their fall; 2. Techniques that do not prevent loose blocks from falling, but attempt to reduce the risk of rockfall ...

This chapter will consider hillslopes with gradients less than 40° that are neither active, undissected piedmonts (i.e. pediments and alluvial fans, which are dealt with in Chapters 13 and 14) nor are developed in highly erodible, fine-grained sedimentary rocks (i.e. badlands slopes, which are treated in Chapter 9).
