Second‐Order Between‐Supplier Learning
ABSTRACT Substantial empirical evidence shows that suppliers in emerging economies can enhance their technological capabilities through direct learning from technologically advanced foreign competitors. However, suppliers in emerging markets may struggle to learn directly from knowledge about competitors’ products that are not widely available on the ...

Free‐Breathing, 3D Cardiac Magnetic Resonance Elastography for Myocardial Stiffness Mapping
ABSTRACT Purpose Magnetic resonance elastography (MRE) of the heart has predominantly utilized breath‐held acquisitions with limited anatomic coverage. This work investigates the feasibility of 3D, free‐breathing cardiac MRE. Methods A 3D hybrid radial and EPI acquisition is utilized and combined with retrospective binning of k‐space via physiologic ...

ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Weibull‐Neural Network Framework for Wind Turbine Lifetime Monitoring and Disturbance Identification
ABSTRACT Wind turbines are vital for sustainable energy, yet their reliability under diverse operational and environmental conditions remains a challenge, often leading to costly failures. This study presents a novel Weibull‐Neural Network Framework to enhance wind turbine lifetime monitoring by estimating reliability (R(t)) and mean residual life (MRL)

Power Quality‐Oriented Multiloop Design of Floating Wind Turbines Pitch Control
ABSTRACT Floating offshore wind turbines (FOWTs) face inherent control limitations in above‐rated operating conditions due to right‐half‐plane zeros in the blade‐pitch‐to‐rotor‐speed dynamics, which restrict achievable control bandwidth and may lead to closed‐loop instability.
