Durability of Soft Pneumatic Actuators: A Review and Benchmarking Protocol

open access: yesAdvanced Robotics Research, EarlyView.
Lack of durability is a key challenge hindering the broad scale adoption of soft pneumatic actuators (SPAs) in automation industries. This review provides a comprehensive overview of existing research on SPA durability, introduces a standardized durability benchmarking protocol to consolidate the testing of SPAs, and outlines promising directions for ...

The role of reciprocation in social network formation, with an application to blogging [PDF]

open access: yes
This paper deals with the role of reciprocation in the formation of individuals' social networks, that is to what extent initiating a relation brings about its reciprocation. Following the activity of a panel of bloggers over more than a year, we seek to

Dual‐Mode Gripper With Suction and Shape‐Adaptive Freezing Grasps

open access: yesAdvanced Robotics Research, EarlyView.
This study presents a dual‐mode robotic gripper that combines vacuum suction with a shape‐adaptive freezing grasp. The freezing mode uses a compliant rubber membrane, a sprayed water layer, and dry‐ice powder to generate ice‐mediated adhesion while conforming to complex geometries.

Influence of Thermal Pretreatments on the Cyclic Fatigue Resistance of Novel Reciprocating Nickel-Titanium Files: A Comparison of Low- and High-Temperature Modified Systems

open access: yesEuropean Endodontic Journal
Introduction: The flexibility and fracture resistance of nickel-titanium (NiTi) files have revolutionised root canal preparation—but file fractures caused by cyclic fatigue or torsional failure are challenging.

Rethinking Reciprocity

open access: yesAnnual Review of Economics, 2014
Reciprocal behavioral has been found to play a significant role in many economic domains, including labor supply, tax compliance, voting behavior, and fund-raising. What explains individuals’ tendency to respond to the kindness of others? Existing theories posit internal preferences for the welfare of others, inequality aversion, or utility from ...

Shear‐Isolating Actuation System for Exosuit Using Movable Pulley With Webbing‐Driven Mechanism

open access: yesAdvanced Robotics Research, EarlyView.
Tendon‐driven exosuits can chafe the skin because the moving tendon slides against the wearer. A shear‐isolating actuation system combining a movable pulley with flat‐profile webbing keeps the body‐contacting tendon layer stationary, relocating relative motion away from the skin. The compact 145‐g actuator delivers 150 N of assistance, and benchtop and
