Retina‐Inspired Bi‐Based Terahertz Photonic Neuromorphic Devices
Advanced Science, EarlyView.Combined with effective band alignment and substrate engineering, bismuth materials are introduced to form terahertz photonic bio‐inspired devices with picosecond short‐term plasticity to enable multi‐scene visual perception. Thus obtained hardware through the terahertz optical neural network (THz‐ONN) demonstrates high recognition accuracy, providing ...

The cardiac output monitoring devices based on pulse wave analysis (PWA) became a standard of hemodynamic management in many selected patients in critical and perioperative care. They are known as “minimally invasive” because the only prerequisite is a conventional arterial catheter.

Pulse wave analysis: basic concepts and clinical application in intensive care medicine
Current Opinion in Critical Care, 2023Purpose of review The measurement of cardiac output (CO) is important in patients with circulatory shock. Pulse wave analysis (PWA) estimates CO continuously and in real-time using the mathematical analysis of the arterial pressure waveform.

Pulse Wave Analysis Techniques
The Handbook of Cuffless Blood Pressure Monitoring, 2019Pulse wave analysis, or PWA, is a technique based on the morphological analysis of blood pressure waveforms, whose shape reflects crucial information on the properties of the arterial wall and blood pressure itself. Although the first historical developments of PWA date back to the nineteenth century, the technique started to prosper with the ...

The general deterioration of the arterial system is well recognized but not easily measured. Leg pulse waves, generated by the electric impedance plethysmograph, would seem to be a promising method. This study is a mathematical analysis of these pulse waves from the legs. The data were taken from a previous study by the same authors.

Pulse wave analysis and pulse wave velocity
Journal of Hypertension, 2003The study of the pulse using the technique of applanation tonometry is undergoing a resurgence with the development of new computerized equipment. We aim here to present a critical review of the uses, potential uses, strengths and weaknesses of the technique of applanation tonometry for the assessment of augmentation index and pulse wave velocity.

Pulse wave analysis for the prediction of preeclampsia
Journal of Human Hypertension, 2014Preeclampsia is associated with a number of changes to maternal vascular function. Assessment of arterial stiffness using pulse wave analysis (PWA) has been proposed as a means of predicting preeclampsia before the onset of clinically detectable disease.
