Holographic Visualization of Noise Emissions from a Small Ducted Fan [PDF]

, 2003
Cylindrical Nearfield Acoustical Holography (NAH) based on a multi-scan, cross-spectral measurement was used to visualize the sound field of a ducted fan, and the ability of this procedure to quantify source modification effects is illustrated ...

Artificial Intelligence for Identifying Tumor‐Reactive CD8+ T Cells: Biological Principles, Computational Advances, and Future Directions

Med Research, EarlyView.
This review details a three‐stage paradigm shift for tumor‐reactive CD8+ T‐cell identification: decoding transcriptomic states, deciphering clonal functional efficacy, and molecular‐level therapeutic TCR design. Addressing translational hurdles and generative AI “scientific blind spots”—such as missing catch bonds—we present a visionary roadmap.

Navigating the Complexity: A Comprehensive Review of GSK‐3 Inhibition in Regenerative Medicine

Medicinal Research Reviews, EarlyView.
ABSTRACT Glycogen synthase kinase‐3 (GSK‐3) is a central regulator of numerous cellular signaling pathways, with critical roles in metabolism, proliferation, differentiation, and tissue regeneration. This review explores the multifaceted effects of pharmacological GSK‐3 inhibition across multiple body districts, focusing on its highly context‐dependent

An Adaptive Multiple Shooting Strategy for Optimal Control

Optimal Control Applications and Methods, EarlyView.
We study how multiple shooting affects the convergence of Newton‐type methods for optimal control, comparing several shooting strategies across 40 benchmark problems. The study covers interior‐point and sequential quadratic programming methods with both Quasi‐Newton approximations and exact Hessians.

Regulating Lipid Metabolism in Cancer: The Therapeutic Potential of Traditional Chinese Medicine

Phytotherapy Research, EarlyView.
By regulating the reprogramming of lipid metabolism in tumor cells, TCM provides a novel strategy for antitumor therapy with reduced toxicity and enhanced efficacy. ABSTRACT Lipid metabolic reprogramming is a key feature of tumor cells to adapt to the microenvironment and plays an important role in tumor growth, invasion, and metastasis.

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...
