A More Precise Elbow Method for Optimum K-means Clustering [PDF]

arXiv
K-means clustering is an unsupervised clustering method that requires an initial decision of number of clusters. One method to determine the number of clusters is the elbow method, a heuristic method that relies on visual representation. The method uses the number based on the elbow point, the point closest to 90 degrees that indicates the most optimum

Bioinspired Liquid‐Free Ion‐Conductive Elastomers with Ultrahigh Mechanical Strength and Excellent Ionic Conductivity for Multifunctional Flexible Sensing Applications

Advanced Science, EarlyView.
⁻Inspired by the “brick wall” structure of pearl layer, FLICE‐110% liquid‐free ionic conductive elastomer had high mechanical strength (5.46 MPa), excellent ionic conductivity (3.29 × 10−4 S cm−1) and resilience. It can be used in smart music boxes, airplane wings and control manipulators.

The modern reverse shoulder arthroplasty and an updated systematic review for each complication: part I

JSES International, 2020
Background: Globally, reverse shoulder arthroplasty (RSA) has moved away from the Grammont design to modern prosthesis designs. The purpose of this 2-part study was to systematically review each of the most common complications of RSA, limiting each ...

Replication of Impedance Identification Experiments on a Reinforcement-Learning-Controlled Digital Twin of Human Elbows [PDF]

arXiv
This study presents a pioneering effort to replicate human neuromechanical experiments within a virtual environment utilising a digital human model. By employing MyoSuite, a state-of-the-art human motion simulation platform enhanced by Reinforcement Learning (RL), multiple types of impedance identification experiments of human elbow were replicated on ...

High‐Performance Conductive Elastomers Based on Deep Eutectic Solvents and Polyvinyl Alcohol for Flexible Monitoring Sensors

Advanced Electronic Materials, EarlyView.
A novel conductive elastomer is developed by incorporating deep eutectic solvents into a PVA/Polyacrylic Acid (PAA) network. The synergistic effects of dynamic hydrogen bonds, ionic interactions, and chemical crosslinking result in a highly flexible and dense polymer structure, while the integration of sodium chloride ensures excellent conductivity and

Functional characterization of a novel TP53RK mutation identified in a family with Galloway–Mowat syndrome

Human Mutation, Volume 43, Issue 12, Page 1866-1871, December 2022., 2022
Abstract Galloway–Mowat syndrome (GAMOS) is a very rare condition characterized by early‐onset nephrotic syndrome and microcephaly with variable neurologic features. While considerable genetic heterogeneity of GAMOS has been identified, the majority of cases are caused by pathogenic variants in genes encoding the four components of the Kinase ...
