On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

Mathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

MRI of Neurogenic Human Motor Units Following Poliomyelitis

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Surviving motor units in neurogenic diseases demonstrate collateral reinnervation. Scanning electromyography (EMG) reveals normal motor unit corridor length, but with “silent regions,” suggesting that reinnervation does not result in increased motor unit size but may increase motor unit complexity.

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers

Journal of the American Heart Association, EarlyView., 2021
Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.

Superimposed Sacrificial Texturing to Enhance the Optical Performance in Thin‐Film Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Sacrificial texturing method using controlled etching of undoped zinc oxide and indium‐doped tin oxide generates microscale and nanoscale textures on glass. Roughness on two different scales is superimposed to create a new texture capable of broad‐spectrum scattering, which is utilised in thin‐film silicon solar cells to enhance optical performance ...

Quantification of Alkali‐Fluoride Nanoparticle Dissolution in Aqueous Media as a Function of Crystallinity and Surface Modification

Particle &Particle Systems Characterization, EarlyView.
Fluoride release kinetics from uncoated and coated β−NaYF4$\ubeta-{\rm NaYF}_4$ and LiYF4${\rm LiYF}_4$ in aqueous solutions are quantified using an ion‐selective electrode coupled to a dialysis compartment. TEM/DLS/ICP‐OES and speciation‐aware modeling complement the fluoride release results.
