Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control
Advanced Optical Materials, EarlyView.This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.

Complex wavelet coherence for EEG analysis
, 2018 Существует множество методов анализа функциональной связности областей мозга, активность которых регистрируется посредством электроэнцефалографии (ЭЭГ). Одной из надежных и эффективных метрик для оценки взаимодействия ЭЭГ-сигналов является мнимая часть когерентности, которая основана на преобразовании Фурье.

Advanced Optical Materials, EarlyView.This work presents an electrically controllable approach to spin–valley polarization in monolayer WS2 by integrating it with a dual‐mode liquid crystal laser. Applying an external field triggers phase transitions that switch the laser emission between helicity‐defined band‐edge lasing and unpolarized random lasing.
