King and Cochrane: The technological treadmill and racial inequity in US agriculture

Applied Economic Perspectives and Policy, EarlyView.
Abstract Between 1920 and 1969, the number of Black farmers in the US decreased from 14% of all operators to 4%. Using Martin Luther King Jr.'s critique of agricultural policy and Willard Cochrane's theory of the technological treadmill, we explore how racial discrimination was linked to policies that led to structural change in US agriculture.

Comparative Life Cycle Assessment of Perovskite Solar Cell Production: Mesoporous n‐i‐p Versus Inverted p‐i‐n Architectures

Advanced Energy and Sustainability Research, EarlyView.
This work assesses the environmental impacts associated with the production of perovskite solar cells (PSCs) with two different architectures, mesoporous n‐i‐p and inverted p‐i‐n, using the life cycle assessment methodology. Results indicate that producing mesoporous n‐i‐p PSCs has higher environmental impacts than producing inverted p‐i‐n PSCs, due to

Protective and Collision‐Sensitive Gel‐Skin: Visco‐Elastomeric Polyvinyl Chloride Gel Rapidly Detects Robot Collision by Breaking Electrical Charge Accumulation Stability

Advanced Intelligent Systems, EarlyView.
For safe human–robot collaboration (HRC), a protective and collision‐sensitive robot skin is proposed. The developed robot skin, named Gel‐Skin, is composed of polyvinyl chloride (PVC) gel, which is a functional material with impact absorption capability and tunable piezoresistive characteristics based on electrical charge‐accumulation.

Spring and Power in Hovering Ornithopters

Advanced Intelligent Systems, EarlyView.
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Harnessing Deep Learning of Point Clouds for Morphology Mimicking of Universal 3D Shape‐Morphing Devices

Advanced Intelligent Systems, EarlyView.
Soft robots capable of morphing into various 3D shapes are crucial for applications like human‐machine interfaces and biological manipulation. However, controlling 3D shape‐morphing robots with soft actuators remains a challenge. This work introduces a machine learning model that maps complex 3D deformations to control inputs, enabling robots to mimic ...
