Impact of E‐Beam Sterilization on Bioglass Composite Shape Memory Scaffolds

Macromolecular Materials and Engineering, EarlyView.
Electron beam (E‐beam) sterilization is an attractive alternative to conventional methods (e.g., ethylene oxide) to sterilize medical devices such as scaffolds used to heal bone defects. Herein, the impact of E‐beam sterilization on the properties of “self‐fitting” shape memory polymer (SMP) scaffolds prepared from resorbable polyesters and a bioglass ...

Machine Learning for Predictive Modeling in Nanomedicine‐Based Cancer Drug Delivery

Med Research, EarlyView.
The integration of AI/ML into nanomedicine offers a transformative approach to therapeutic design and optimization. Unlike conventional empirical methods, AI/ML models (such as classification, regression, and neural networks) enable the analysis of complex clinical and formulation datasets to predict optimal nanoparticle characteristics and therapeutic

Multiple Indeterminate pulmonary nodules (IPNs) as independent prognostic indicators in pediatric osteosarcoma: A ten-year retrospective study

Journal of Bone Oncology
Background: Osteosarcoma is the most common primary malignant bone tumor in pediatric and adolescent patients. Although pulmonary metastasis is a key driver of prognosis, the role of IPNs in risk stratification remains inadequately defined.

Types of Pain in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Pain affects up to 87% of people with multiple system atrophy (MSA), but it remains unclear which types of pain contribute most to the overall burden. Objective To estimate the frequency of different types of pain in MSA individuals.

Trajectory Control of Manipulator Robots With Uncertainties: A Saturated Continuous Integral Sliding Mode Approach

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study addresses the trajectory tracking control for manipulator robots with uncertainties. The main objective is to ensure that the robot follows a desired trajectory despite the presence of uncertainties/disturbances and considering control input constraints. The approach is developed in the framework of continuous integral sliding modes.

Composition Distribution, Damping and Thermal Properties of the Thickness-Continuous Gradient Epoxy/Polyurethane Interpenetrating Polymer Networks

Applied Sciences, 2017
A thickness gradient interpenetrating polymer network (IPN) was easily created that takes advantage of the relatively poor compatibility and curing rates discrepancy between epoxy (EP) and polyurethane (PU).

A Self‐Healing Conductive PVP/SUM Hydrogel for Real‐Time Human Motion Detection

Nano Select, EarlyView.
The PVP/SUM hydrogel exhibits self‐healing, conductivity, and strong mechanical performance due to H‐bonds and dipole–dipole interactions. It elongates up to 330% and shows fracture strength between 0.9 and 1.5 MPa under varying strain rates. With a conductivity of 3.28 × 10−5 S/cm, it responds rapidly to human motion, enabling real‐time monitoring for

Physically consistent mesoscale model evaluation in complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study introduces a novel approach for evaluating mesoscale atmospheric models in complex terrain by selecting physically consistent grid points and applying height‐based corrections. The method corrects for sensor height and terrain elevation differences between model and observations using a time‐varying lapse rate.
