Whole-Body Inverse Kinematics with Graph Diffusion

Inverse kinematics (IK) is a fundamental problem in robotics, requiring the generation of joint configurations that satisfy target end-effector poses. Existing approaches often struggle to generalize across diverse robot morphologies and to effectively model the multi-modal nature of IK, particularly in articulated systems with multiple kinematic ...

GGMotion: Group Graph Dynamics-Kinematics Network for Human Motion Prediction

2025 6th International Conference on Intelligent Computing and Human-Computer Interaction (ICHCI)
Human motion is a continuous physical process in 3D space, governed by complex dynamic and kinematic constraints. Existing methods typically represent the human pose as an abstract graph structure, neglecting the intrinsic physical dependencies between joints, which increases learning difficulty and makes the model prone to generating unrealistic ...

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

A talus rock glacier in Nantlle Valley, North Wales

Journal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

The effect of calculus and kinematics contexts on students’ understanding of graphs

Eurasia Journal of Mathematics, Science and Technology Education
In this study, we compare students’ understanding of the derivative as slope and the antiderivative as the area under the curve using isomorphic graph-based problems in both calculus and kinematics contexts. Drawing from previous research, we designed two isomorphic tests, each with 12 items, and administered them to 543 university students.

Posterior cruciate ligament involvement leads to inferior outcomes in multiligament knee injuries involving the medial collateral ligament: A systematic review and meta‐analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Multiligament knee injuries (MLKIs) involving the medial collateral ligament (MCL) present unique challenges in surgical management and postoperative rehabilitation. This systematic review and meta‐analysis aimed to evaluate postoperative patient‐reported outcomes in patients with MCL‐involved MLKIs, with a minimum follow‐up of 2 years.

Deep Fusion of Kinematic Features and Task-Aware Partition Planning for Mold Surface Robotic Polishing

Machines
Robotic polishing in CAD-free industrial settings relies on point-cloud data, yet noise and non-uniform sampling often compromise kinematic feasibility and finishing quality.

Targeting ligament boundaries rather than alignment boundaries in augmented‐reality‐assisted total knee arthroplasty ensures comparable gait patterns between operated and contralateral limbs

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modern personalised total knee arthroplasty (TKA) techniques aim to mimic natural knee kinematics by focusing on soft‐tissue dynamics rather than static alignment. However, a consistent definition of the optimal ligamentous balance has not yet been established.

Tibia‐first, gap‐balanced patient‐specific alignment in total knee arthroplasty achieves better ligament balance than mechanical, kinematic and functional alignment strategies

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study evaluates four different alignment techniques to assess total knee arthroplasty (TKA) balance. Methods A prospective cohort of 400 patients undergoing primary robotic‐assisted cruciate‐retaining TKA was analysed. The Velys TKA robotic system collects a balance curve that enables the surgeon to intraoperatively analyse the ...
