Dragonfly Visual Attention–Merged Evolutionary Neural Network Solving Ultrahigh Dimensional Global Optimization Problems

open access: yesInternational Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.
Dragonfly visual systems intrinsically incorporate a variety of motion‐sensitive neurons able to be well contributed to probe into bio‐inspired computational models. However, it remains unclear how their visual response mechanisms can be borrowed to construct neurocomputational models for solving optimization problems.

Improved Heat Transfer Capabilities of Nanofluids—An Assessment Through CFD Analysis

open access: yesChemical Engineering &Technology, Volume 47, Issue 11, November 2024.
Conventional fluids used in fission‐based water‐cooled nuclear reactors have lower heat transfer coefficients and thermal conductivity, prompting researchers to explore high‐performance fluids to enhance heat transfer and prevent core meltdown during accidents. It is crucial to investigate fluids that can improve thermal hydraulic characteristics, such

Time to Functional Loss as an Endpoint in Huntington's Disease Trials: Enrichment and Sample Size

open access: yesMovement Disorders, Volume 39, Issue 10, Page 1809-1816, October 2024.
Abstract Background Clinical trial scenarios can be modeled using data from observational studies, providing critical information for design of real‐world trials. The Huntington's Disease Integrated Staging System (HD‐ISS) characterizes disease progression over an individual's lifespan and allows for flexibility in the design of trials with the goal of
