Hell's Itch: A Self‐Case Report

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Hell's itch is a severely distressing dermatological condition characterized by the onset of incessant itching and intolerable pain 2–3 days post‐sunburn. It is underdiagnosed and underreported, and no definitive management framework has yet been developed.

Bayesian Optimization of Grayscale Patterns for Layer‐Height Accuracy in Projection Multi‐Photon 3D Printing

open access: yesLaser &Photonics Reviews, EarlyView.
Bayesian optimization combined with in situ quantitative phase imaging enables autonomous correction of layer‐height deviations in projection multi‐photon lithography. By jointly tuning model parameters and grayscale exposure settings, the method achieves more uniform and accurate layers within 300 prints, offering a fast, data‐efficient route to ...

Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts

open access: yesLaser &Photonics Reviews, EarlyView.
Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...

Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

open access: yesLaser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

open access: yesLaser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Lonely and Sick: The Role of Social Media in Consumer Practices of Relief

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Loneliness is increasingly recognized as a major mental health concern, yet the role of social media in alleviating it remains poorly understood. This study asks how social media help consumers cope with loneliness amid chronic illness. Focusing on women living with endometriosis, an under‐recognized and often stigmatized condition marked by ...

Long‐Term Institutional Ownership and Corporate Breakthrough Innovation: Evidence From the Perspective of Patient Capital

open access: yesManagerial and Decision Economics, EarlyView.
ABSTRACT This paper examines whether institutional ownership with different investment horizons is related to corporate breakthrough innovation, using panel data of Chinese A‐share listed firms from 2014 to 2023. Long‐term institutional ownership is positively and significantly associated with breakthrough innovation, while short‐term institutional ...

The Audiologic and Otolaryngologic Phenotype in WHIM Syndrome

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective WHIM syndrome (warts, hypogammaglobulinemia, infections, and myelokathexis syndrome) is an ultra‐rare primary immunodeficiency disease caused by autosomal dominant hyperfunctional mutations in the chemokine receptor CXCR4. Otolaryngologists are frequently consulted to evaluate WHIM patients because of recurrent acute ear and sinus ...
