Advancements in Carbon‐Based Piezoelectric Materials: Mechanism, Classification, and Applications in Energy Science

open access: yesAdvanced Materials, EarlyView.
Carbon‐based piezoelectric materials are systematically categorized based on their structural and functional properties. The mechanisms of stress‐induced charge transfer are elucidated, and their applications are explored across three key domains: piezoelectric catalysis for energy conversion and environmental remediation, piezoelectric biomedical ...

Biomechanical models to simulate consequences of maxillofacial surgery [PDF]

open access: yesC. R. Biologies 325 (2002) 407-417, 2006
This paper presents the biomechanical finite element models that have been developed in the framework of the computer-assisted maxillofacial surgery. After a brief overview of the continuous elastic modelling method, two models are introduced and their use for computer-assisted applications discussed. The first model deals with orthognathic surgery and

Characterization and Inverse Design of Stochastic Mechanical Metamaterials Using Neural Operators

open access: yesAdvanced Materials, EarlyView.
This study presents a DeepONet‐based machine learning framework for designing stochastic mechanical metamaterials with tailored nonlinear mechanical properties. By leveraging sparse but high‐quality experimental data from in situ micro‐mechanical tests, high predictive accuracy and enable efficient inverse design are achieved.

Jet-Ricci Geometry of Time-Dependent Human Biomechanics [PDF]

open access: yesarXiv, 2009
We propose the time-dependent generalization of an `ordinary' autonomous human biomechanics, in which total mechanical + biochemical energy is not conserved. We introduce a general framework for time-dependent biomechanics in terms of jet manifolds derived from the extended musculo-skeletal configuration manifold.

Challenges of Soft Tissue Integration Around Dental Implants and Strategies Based on Material Surface Modification

open access: yesAdvanced Materials Interfaces, EarlyView.
Peri‐implant soft tissue integration (STI), weaker than natural teeth, raises peri‐implant disease risk. Gingival‐region material surface properties critically modulate soft‐tissue responses, driving surface modifications to enhance STI. This review provides an in‐depth analysis of the challenges of STI around dental implants, comprehensively reviews ...

Effect of Forward Head Posture on Erector Spinae Muscle Activity

open access: yesPhysical Therapy Korea
Background: For instance, forward head posture (FHP), characterized by the forward move-ment of the head relative to the spine, places significant stress on the neck and upper back muscles, disrupting the biomechanical balance of the body.
