Unsupervised Low‐Light Image Enhancement via Adaptive Dual‐Path Frequency Network

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We propose dual‐path adaptive frequency network, an unsupervised lightweight network for low‐light image enhancement that performs adaptive illumination correction through decoupled enhancement modelling and frequency‐aware attention. Experiments on public datasets show that the proposed method achieves competitive visual quality with low computational

Assessment of cerebrovascular reactivity with the TCD through the submandibular window

Discover Medicine
Purpose Cerebrovascular reactivity (CVR) is commonly assessed via transcranial Doppler ultrasonography (TCD) through the temporal bone window. However, inadequate temporal acoustic window in some individuals necessitates alternative approaches.
