Abstract Melt electrowriting (MEW) is a solvent‐free (i.e., no volatile chemicals), high‐resolution three‐dimensional (3D) printing method that enables the fabrication of semi‐flexible structures with rigid polymers. Despite its advantages, MEW process sensitive to changes in parameters (e.g., voltage, pressure, and temperature), which can cause fluid column breakage, jet lag, and/or fiber pulsing, ultimately deteriorating resolution quality. In spite commonly used error‐and‐trial determine...

Human monkeypox (Mpox) is a zoonotic disease caused by the Monkeypox virus (MPXV). As of 14 August 2024, World Health Organization (WHO) has declared it global health emergency. For Mpox, this was second public emergency significance in past two years. MPXV belongs to Poxviridae family and phylogenetically epidemically divided into clades: Congo Basin (Clade-I) West African (Clade-II) clades. Clade-I been associated with more severe progression higher mortality compared Clade-II, thus...

Abstract Microneedles (MNs) have emerged as a promising solution for drug delivery and extraction of body fluids. Pain is an important physiological attribute to be examined when designing MNs. There no known representation pain with geometric features MN despite the focus on experimental work. This study focuses optimizing designs aim minimizing through means machine learning, finite element analysis, optimization tools. Three distinct approaches are proposed. The first approach involves...

Microneedles (MNs), that is, a matrix of micrometer-scale needles, have diverse applications in drug delivery, skincare therapy, and health monitoring. MNs offer minimally invasive alternative to hypodermic characterized by rapid painless procedures, cost-effective fabrication methods, reduced tissue damage. This study explores four MN designs, cone-shaped, tapered pyramidal with square base, triangular-shaped their optimization based on predefined criteria. The workflow encompasses three...

Computer vision systems play a major role in many areas of life, as reliance has clearly begun on these the medical field, where they help doctors diagnose diseases correctly. In addition, are relied upon sports can referees giving correct arbitration decisions. The accuracy computer increased with emergence deep learning techniques, which require large amount data model be trained. Therefore, if any is to detect and distinguish movement or entity within images video clips, it must first...

In this paper, we are using enhancing feedback control on a new continuous 4D autonomous hyper chaotic system proposed by Sadiq A. Mehdi and Hayder, Qasim [Analysis of New Hyperchaotic System with six cross-product nonlinearities terms, 2017], has three critical points employs ten terms include quadratic nonlinearity We notice that when apply any linear method relies single unit added to the system, behavior in case cannot it, so applied at origin noticed necessary condition for suppression...

The most popular defects that infect new born babies have close connection with heart. Approximately 1% percent of suffering from are caused by By observing Electrocardiogram "ECG" during gestation doctors can study the fetal heart activity collected mother abdominal and rectify number which has been diagnosed in Many techniques like filters, BSS even artificial intelligence used to extract process ECG signal. In case twins problem would be more complicated because recorded signal is a...
