Neural self-organization for muscle-driven robots [PDF]

arXiv, 2023
We present self-organizing control principles for simulated robots actuated by synthetic muscles. Muscles correspond to linear motors exerting force only when contracting, but not when expanding, with joints being actuated by pairs of antagonistic muscles.

The energy of muscle contraction. II. Transverse compression and work [PDF]

, 2020
In this study we reproduced this compression-induced reduction in muscle force through the use of a three-dimensional finite element model of contracting muscle. The model used the principle of minimum total energy and allowed for the redistribution of energy through different strain energy-densities; this allowed us to determine the importance of the ...

Ex Vivo Preservation of Porcine Vascularized Composite Soft Tissue Allografts

Artificial Organs, EarlyView.
The aim of this study was to evaluate the effectiveness of ex vivo perfusion (EVP) for vascularized composite tissue preservation. EVP preserved abdominal free flaps for 24 h within physiologic parameters and without development of edema. EVP may extend preservation time and geographic reach for VCAs.ABSTRACTIntroductionThe aim of this study was to ...

Bayesian Recursive and Structural Equation Models to Infer Causal Links Among Gait Visual Scores on Campolina Horses

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Gait visual scores are widely applied to horse breeding because they are a fast and easy phenotyping strategy, allowing the numeric interpretation of a complex biological process such as gait quality. However, they may suffer from subjectivity or high environmental influence.

Agent-based Modeling and Simulation of Human Muscle For Development of Human Gait Analyzer Application [PDF]

arXiv, 2022
Despite the fact that only a small portion of muscles are affected in motion disease and disorders, medical therapies do not distinguish between healthy and unhealthy muscles. In this paper, a method is devised in order to calculate the neural stimuli of the lower body during gait cycle and check if any group of muscles are not acting properly.

Novel Therapeutic Algorism in Patients With Anterior Cutaneous Nerve Entrapment Syndrome

Neurology and Clinical Neuroscience, EarlyView.
ABSTRACT Background Anterior cutaneous nerve entrapment syndrome (ACNES) is often overlooked as a cause of chronic abdominal pain. Trigger point injections (TPIs) serve as both a diagnostic and therapeutic tool. Although neurectomy is frequently chosen for patients with severe ACNES, its surgical outcomes remain unclear. Aim This study aims to evaluate

Towards an efficient inverse static model of a Festo actuator made of two antagonist muscles for hybrid control of its position and stiffness [PDF]

arXiv, 2021
The Festo air muscle is today one of the most known commercial version of the so-called McKibben pneumatic artificial muscle. A major advantage of handmade McKibben muscles, as well as its commercial versions, lies in the possibility it offers of realizing antagonist muscle actuator on the model of the biceps-triceps system.
