Computerized electrocardiogram data transformation enables effective algorithmic differentiation of wide QRS complex tachycardias

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Accurate automatic wide QRS complex tachycardia (WCT) differentiation may be accomplished through the use of novel parameters derived from computerized data of the (i) WCT electrocardiogram (ECG) alone and (ii) paired WCT and baseline ECGs. Once automated WCT differentiation models are integrated into commercially available computerized ECG ...

Recent Advances in Dielectric Chiral Metasurfaces

Advanced Physics Research, EarlyView.
This review article mainly focuses on the recent advances in dielectric chiral metasurfaces, which exhibit remarkable optical chirality. Many new physical conceptions will be introduced during the fast development of the dielectric chiral metasurfaces, such as chiral quasi‐BIC, chiral guided modes, and nonlocal metasurfaces.

Ophthalmic imaging in diabetic retinopathy: A review

Clinical &Experimental Ophthalmology, Volume 50, Issue 9, Page 1082-1096, December 2022., 2022
Abstract Retinal imaging has been a key tool in the diagnosis, evaluation, management and documentation of diabetic retinopathy (DR) and diabetic macular oedema (DMO) for many decades. Imaging technologies have rapidly evolved over the last few decades, yielding images with higher resolution and contrast with less time, effort and invasiveness.

Higher-resolution wavefront sensing based on sub-wavefront information extraction

Frontiers in Physics
The limited spatial sampling rates of conventional Shack–Hartmann wavefront sensors (SHWFSs) make them unable to sense higher-order wavefront distortion.

Hyperspectral wavefront sensing with a multicore fiber [PDF]

arXiv
Single-shot hyperspectral wavefront sensing is essential for applications like spatio-spectral coupling metrology in high power laser or fast material dispersion imaging. Under broadband illumination, traditional wavefront sensors assume an achromatic wavefront, which makes them unsuitable. We introduce a hyperspectral wavefront sensing scheme based on
