Topology optimization for near-junction thermal spreading of electronics in ballistic-diffusive regime

open access: yesiScience, 2023
Summary: Hotspots in electronic devices can cause overheating and reduce performance. Enhancing the thermal spreading ability is critical for reducing device temperature to improve the reliability. However, as devices shrink, phonon ballistic effects can

Constriction Resistance and Current Crowding in Vertical Thin Film Contact

open access: yesIEEE Journal of the Electron Devices Society, 2013
The constriction resistance and the current flow pattern are calculated analytically in a vertical thin film contact in which the thin film base is an equipotential surface. Both Cartesian and cylindrical thin film contacts are studied. The resistivities

Spreading of Antimicrobial Resistance Across Clinical Borders

open access: yesErciyes Medical Journal, 2019
Spreading of antibiotic resistance is effective via many routes and is dependent on the setting. Moreover, poor hygiene conditions, poor sanitation, as well as inadequate infection control contribute to the spreading of resistant bacteria in health care ...

Whole-Genome Sequencing of Pathogenic Bacteria—New Insights into Antibiotic Resistance Spreading

open access: yesMicroorganisms, 2021
In recent years, the acquisition of antimicrobial resistance (AMR) by both pathogenic and opportunistic bacteria has become a major problem worldwide, which was already noticed as a global healthcare threat by the World Health Organization [...]

Shared and Unique Evolutionary Trajectories to Ciprofloxacin Resistance in Gram-Negative Bacterial Pathogens

open access: yesmBio, 2021
The challenge of spreading antibiotic resistance calls for systematic efforts to develop more “irresistible” drugs based on a deeper understanding of dynamics and mechanisms of antibiotic resistance acquisition.

Numerical Investigation of the Impact of a Hollow Ceramic Droplet on Metallic Substrate [PDF]

open access: yesJournal of Applied Fluid Mechanics
The objective of this study is to numerically investigate the spreading and solidification of a hollow ceramic droplet impacting a metallic substrate, with a particular focus on the melting of the substrate. The numerical model employs the PISO (Pressure-

Spreading vasodilatation in resistance arteries

open access: yesJournal of Smooth Muscle Research, 2005
Focal application of vasodilators such as acetylcholine (ACh), which evoke arterial hyperpolarization, cause coordinated dilatation along the length of an artery with minimal decay with distance from the site of application. This phenomenon is called spreading vasodilatation.
