Necrotising Infundibular Crystalline Folliculitis: A Rare Case With a Microscopic Abundance of Yeasts

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT A 66‐year‐old man presented with a 5‐year history of recurrent pruritic, waxy folliculocentric papules on his trunk which worsened during winter and minimally responded to selenium sulphide shampoo and topical corticosteroids. Skin biopsy demonstrated a dilated follicular infundibulum containing abundant yeasts and amorphous material with ...

Dynamics of Vector Soliton Singlets and Pairs in Self‐Mode‐Locked Tm‐Doped Fibre Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
This study characterises soliton build‐up dynamics in a self‐mode‐locked Tm‐doped fibre laser, where both cavity birefringence and distributed saturable absorber play significant roles in the intracavity pulse shaping. The recorded single‐shot spectra using the dispersive Fourier transform technique reveal intensity‐dependent temporal splitting of ...

Tightly‐Confined and Long Z‐Cut Lithium Niobate Waveguide with Ultralow‐Loss

open access: yesLaser &Photonics Reviews, EarlyView.
A z‐cut lithium niobate waveguide is demonstrated with ultra‐low loss of 5.8 dB/m in a decimeter‐long LN spiral waveguide. This study is focused on Z‐cut LN waveguides with TE mode to avoid the material birefringence. Utilizing the third order nonlinearity, it is demonstrated that the first all‐normal‐dispersion coherent supercontinuum frequency comb ...

Higher Speed Multispectral Imaging Using a Thin Liquid Crystal Layer in Metal Cavity and Artificial Intelligence Reconstruction Algorithm

open access: yesLaser &Photonics Reviews, EarlyView.
A rapid multispectral imaging system is presented that integrates a 4 µm‐thick liquid crystal spectral modulator in a metal–insulator–metal (MIM) configuration with a multi‐bandpass filter (MBF). Coupled with a custom AI‐based reconstruction algorithm, the system enables accurate food quality monitoring and demonstrates the potential to capture a ...
