Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals
Laser &Photonics Reviews, EarlyView.The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

Review on Processing Control Strategy for Electrochemical Additive Manufacturing
MetalMat, EarlyView.This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose In the spinal cord (SC), multi‐echo gradient echo (ME‐GRE) increases gray (GM) and white matter (WM) contrast and improves sensitivity to lesions in people with multiple sclerosis (pwMS). However, SC ME‐GRE is susceptible to breathing‐induced field fluctuations, causing ghosting artifacts and signal loss.

Nonstationarity in wildlife disease dynamics: insights from the prairie dog–plague system
Oikos, EarlyView.Ecological relationships often vary in strength and direction across ecosystems, a pattern that has become increasingly evident as ecology expands to broader spatial and temporal scales. Although such nonstationarity – the changing effect of predictor variables across spatiotemporal contexts – is widely acknowledged in ecological research, it has ...

Pest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

Hatching and fledging? A meta‐analysis of the performance effects of business incubators
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Business incubators are among the most widely implemented instruments to foster entrepreneurship. Yet empirical evidence on their effectiveness remains fragmented and often contradictory. Limited research systematically compares how different types of incubators influence multiple venture performance outcomes, including ...
