Robotic Interventional Needle Insertion Assisted by a Cable‐Driven Parallel Robot

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 1, January 2026.
This article presents a body‐mounted cable‐driven parallel robot assisting the needle insertion procedure designated for automated interventional pain therapy. The 3D‐printed robot body and multiple thin cables can achieve high X‐ray compatibility for intervention. The robot performs full 6‐degree of freedom needle insertion and remote center of motion

Custom Shape Formation in Continuum Robots Using Compliant Bistable Segments for Medical Applications

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 1, January 2026.
This article describes the integration of compliant bi‐stability in continuum robots. This integration leads to two variants of compliant bistable mechanism (CBM) integrated continuum robot segments, extending and locking. Results show that when used together, these CBM‐integrated segments allow the continuum robot to form custom shapes.

PROFILE MODIFICATION INFLUENCE ON THE CONTACT RATIO FOR STRAIGHT BEVEL GEAR

open access: yesJournal of Industrial Design and Engineering Graphics, 2007
Bevel gear, as octoidal gear, is not accurate involute. As a result, unlike involute cylindrical gear, bevel gear is accomplished by using profile which are not modification or profile with zero modification.

ACT‐Agent: Affinity‐Cross Transformer for Point Cloud Registration via Reinforcement Learning

open access: yesIET Image Processing, Volume 20, Issue 1, January/December 2026.
1. We proposed a point cloud registration framework combining imitation learning and reinforcement learning, which formulates the registration problem as a Markov decision process with discrete action sequences. 2. We designed the Affinity‐Cross Transformer module to enhance the point cloud feature representation and interaction capabilities. 3.

The Impact of a Buyer's Incentives and Organizational Structure on Suppliers' Quality

open access: yesJournal of Operations Management, Volume 71, Issue 8, Page 1185-1221, December 2025.
ABSTRACT Changes in a buyer organization's incentives and structure can have a significant impact on supply chain performance, such as the quality of sourced components. We examine this relationship using data from a unique quasi‐experiment where one of the two plants of a buyer introduced long‐term quality improvement incentives and a more organic ...
