Hybrid Reaction–Diffusion Epidemic Models: Dynamics and Emergence of Oscillations

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we construct a hybrid epidemic mathematical model based on a reaction–diffusion system of the SIR (susceptible‐infected‐recovered) type. This model integrates the impact of random factors on the transmission rate of infectious diseases, represented by a probabilistic process acting at discrete time steps.

Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...

Timing Is Everything: How Subtle Timing Changes in MRI Echo Planar Imaging Can Significantly Alter Mechanical Vibrations and Sound Level

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Echo‐Planar Imaging (EPI) is central to fMRI, diffusion MRI, and many dynamic clinical applications, yet rapid gradient switching induces strong mechanical vibrations, generates acoustic noise, and contributes to ghosting artifacts—effects that intensify at ultra‐high fields.

Influence of EDTA Coverage Density on Optical Fiber Sensor for Heavy Metal Ion Detection

Nano Select, EarlyView.
This study investigates the influence of chelating agent coverage on the performance of optical fiber sensors for heavy metal ion detection. Ethylenediaminetetraacetic acid (EDTA) was employed to functionalize single‐mode 28 optical fibers (SMF‐28), and the influence of surface coverage uniformity on zinc ion sensing performance was investigated ...

Mental health benefits of urban green—A systematic review and meta‐analysis of 56 pre‐post control experiments

People and Nature, EarlyView.
Abstract Background. Fostering healthy urban living conditions is a critical public health objective. One efficient approach lies in the contact to nature, as numerous studies have shown that urban and peri‐urban natural elements both indoors and outdoors carry a large potential in buffering typical urban threats to mental health.
