Exploring New Chemical Paths in Quantum AI: Preliminary Accomplishments and Future Perspectives

Advanced Quantum Technologies, EarlyView.
Two new strategies derived from Chemical AI to promote the advancement of sustainable quantum technologies are presented and discussed. The first strategy relies on the chemical implementation of molecular fuzzy sets, which are quantum mixed states associated with chemical microheterogeneous systems. The second strategy relies on photochromic compounds

Dynamic Resource Allocation for LEO Satellite Systems Under Heterogeneous Traffic Distributions

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes an efficient resource allocation scheme for low Earth orbit (LEO) satellite systems. Taking into account the unique characteristics of LEO systems for 6G communication services, we introduce a dynamic bandwidth and power allocation scheme specifically designed to accommodate highly heterogeneous traffic distributions.

Tailorable Nanoparticles for Magnetic Water Cleaning of Polychlorinated Biphenyls

Small Methods, EarlyView.
Polychlorinated biphenyls (PCBs) are human‐made persistent organic pollutants omnipresent in the earth's hydrosphere, which are reported hazardous to humans as well as wildlife. This study presents surface functionalized magnetic nanoparticles that can remove such contaminants from water with an adjustable preference for most concerning compounds ...

Dynamic coronary roadmap-guided PCI reduces contrast volume and radiation time compared to standard angiography PCI: A meta-analysis

Heliyon
Background: Dynamic Coronary Roadmap (DCR) is a new PCI method that may reduce contrast dose and contrast-associated acute kidney injury (CA-AKI) risk. This paper evaluates DCR-guided PCI versus standard angiography PCI for contrast usage, procedure time,

Minimization of Porosity in E11018‐G Low‐Alloyed Steel Processed by Laser Powder Directed Energy Deposition

steel research international, EarlyView.
The processability of the E11018‐G by laser powder directed energy deposition (LP‐DED) is investigated. The effects of powder moisture, ambient humidity, and laser remelting on LP‐DED parts’ porosity are shown. A strong influence of the atomizing gas is observed.

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, EarlyView.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a
