Efficacy of Negative Pressure Suction‐Assisted Flexible Ureteroscopy for Upper Urinary Tract Calculi and Construction of a Stone‐Free Rate Prediction Model

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study retrospectively analyzed 92 patients who underwent negative‐pressure suction sheath‐assisted flexible ureteroscopic lithotripsy (observation group) and 85 patients who underwent conventional flexible ureteroscopic lithotripsy (control group).

Quantization of Polaritons Confined in Dielectric Structures

open access: yesLaser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Revealing the Resonant Physics of Open Photonic Time Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

How Servicescapes Come to Feel Like Home: Reciprocal Social Exchange and the Development of Third Place Perceptions

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Amid rising loneliness and declining community participation, service environments have become increasingly important sites of everyday social interaction. Existing research has largely treated Third Place as a property of a space, leaving unexplored how individual customers come to perceive a servicescape as a social home.

When Bad Feels Better: How Negative Online Brand Engagement Transforms Into Consumer Happiness

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Brands are increasingly prioritizing consumer happiness alongside profit, yet research offers limited guidance on fostering this in negative consumer‐brand contexts. Drawing on the broaden‐and‐build theory, this work models consumer pathways from anti‐consumption and disidentification to negative cognition and affection, to constructive and ...

Breaking Extrapolation Barriers: Dual Innovations for Property and Component Design of Multi‐Component Alloy

open access: yesMaterials Genome Engineering Advances, EarlyView.
This study breaks extrapolation barriers in alloy design by merging symbolic regression with latent space sampling. The dual‐strategy framework enables accurate prediction of high‐hardness properties and navigates uncharted compositional spaces. The approach successfully designs novel high‐entropy alloys with hardness exceeding 863.5 HV, demonstrating ...

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Designing Nonprofit Success: A Systematic Review of Board Design Choices and Organizational Performance

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT I synthesize 78 studies from leading nonprofit and public administration journals to explain why research on board design choices, board effectiveness, and organizational performance yields inconsistent findings. The analysis reveals that empirical contradictions stem primarily from theoretical misalignment and measurement diversity rather ...
