Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Dynamical Analysis of an HIV Infection Model Including Quiescent Cells and Immune Response

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This research gives a thorough examination of a human immunodeficiency virus (HIV) infection model that includes quiescent cells and immune response dynamics in the host. The model, represented by a system of ordinary differential equations, captures the complex interaction between the host's immune response and viral infection.

Quantifying physiological variability and improving reproducibility in 4D‐flow MRI cerebrovascular measurements with self‐supervised deep learning

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To assess the efficacy of self‐supervised deep learning (DL) denoising in reducing measurement variability in 4D‐Flow MRI, and to clarify the contributions of physiological variation to cerebrovascular hemodynamics. Methods A self‐supervised DL denoising framework was trained on 3D radially sampled 4D‐Flow MRI data.

Assessing cerebral microvascular pulsatility using flow pulsatile‐resolved pseudo‐continuous arterial spin labeling MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a flow pulsatile‐resolved pseudo‐continuous arterial spin labeling (FPR‐pCASL) technique for noninvasively assessing cerebral microvascular pulsatility. Methods In FPR‐pCASL, a pCASL sequence with single‐shot three‐dimensional gradient and spin echo acquisition was performed while simultaneously recording cardiac pulse ...

Neohypoplasticity for Sand Coupled With the Generalized Intergranular Strain Concept

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This work presents the coupling of the recently revisited advanced hypoplastic constitutive sand model called neohypoplasticity (NHP) with the more recently introduced concept of the generalized intergranular strain (GIS) to account for soil behavior due to small strains. The latter is essential for the simulation of cyclic deformations.

CuO Nanoparticles: Tuning Properties for Energy and Optoelectronic Applications

open access: yesNano Select, EarlyView.
CuO nanoparticles have gained attention for their versatility in energy conversion, catalysis, and optoelectronics. Their properties—such as crystallinity, particle size, and bandgap energy—can be fine‐tuned by adjusting synthesis conditions like temperature, precursor concentration, and reaction time.

Abundant Neighborhoods, Two‐Sided Markets, and Maximal Matchings

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT I introduce a new graph‐theoretic property called abundant neighborhoods. This property is motivated by studying the thickness of economic markets. A vertex is, roughly, guaranteed to match if and only if it has an abundant neighborhood.
