Imaging Ultrasound Propagation Using the Westervelt Equation by the Generalized Kudryashov and Modified Kudryashov Methods
(MDPI, 2022-11-21)
This article deals with the study of ultrasound propagation, which propagates the mechanical vibration of the molecules or of the particles of a material. It measures the speed of sound in air. For this reason, the third-order ...
Experimental Study of AM and PM Noise in Cascaded Amplifiers
(MDPI, 2022-02-05)
An experimental study of amplitude modulation (AM) and phase modulation (PM) noise spectra in cascaded amplifiers was carried out as a function of the number of amplification stages and the input power. Flicker and white ...
Solution to Integral Equation in an O-Complete Branciari b-Metric Spaces
(MDPI, 2022-12-13)
In this paper, we prove fixed point theorem via orthogonal Geraghty type α-admissible contraction map in an orthogonal complete Branciari b-metric spaces context. An example is presented to strengthen our main result. We ...
New Results for Multivalued Mappings in Hausdorff Neutrosophic Metric Spaces
(MDPI, 2022-12-13)
The fundamental goal of this paper is to derive common fixed-point results for a sequence of multivalued mappings contained in a closed ball over a complete neutrosophic metric space. A basic and distinctive procedure has ...
Implementable hybrid quantum ant colony optimization algorithm
(Springer, 2022-12)
We propose a new hybrid quantum algorithm based on the classical Ant Colony Optimization algorithm to produce approximate solutions for NP-hard problems, in particular optimization problems. First, we discuss some previously ...
Fe xCo1-x alloy nanoparticles: Synthesis, structure, magnetic characterization and magnetorheological application
(Elsevier, 2022-12)
We present results concerning the synthesis of FexCo1-x (0 < x < 1) alloy nanoparticles (NPs) with different compositions by the chemical reduction technique and subsequent structural (XRD patterns), morphological (TEM ...
Antibacterial Activity Testing Methods for Hydrophobic Patterned Surfaces
(Nature, 2021-03-23)
One strategy to decrease the incidence of hospital-acquired infections is to avoid the survival of pathogens in the environment by the development of surfaces with antimicrobial activity. To study the antibacterial behaviour ...
Proposal of New Safety Limits for In Vivo Experiments of Magnetic Hyperthermia Antitumor Therapy
(MDPI, 2022)
Background: Lately, major advances in crucial aspects of magnetic hyperthermia (MH) therapy have been made (nanoparticle synthesis, biosafety, etc.). However, there is one key point still lacking improvement: the magnetic ...
Biochemical and Metabolomic Changes after Electromagnetic Hyperthermia Exposure to Treat Colorectal Cancer Liver Implants in Rats
(MDPI, 2021-05-17)
Background: Hyperthermia (HT) therapy still remains relatively unknown, in terms of both its biological and therapeutic effects. This work aims to analyze the effects of exposure to HT, such as that required in anti-tumor ...
Viscosity Approximation Methods for * −Nonexpansive Multi-Valued Mappings in Convex Metric Spaces
(MDPI, 2020-01-17)
In this paper, we prove convergence theorems for viscosity approximation processes involving * −nonexpansive multi-valued mappings in complete convex metric spaces. We also consider finite and infinite families of such ...
