LTMS-S is a new wearable system for the monitoring of several physiological signals – including a twolead electrocardiogram (ECG) – and parameters, such as the heart rate, the breathing rate, the peripheral oxygen saturation ...

Organic-inorganic halide perovskite solar cells show increasing power conversion efficiencies, approaching the values of silicon-based devices. To date, however, most of the reported record efficiencies for perovskite solar ...

Building robust predictive machine learning (ML) models requires access to large datasets. Such datasets can be built by aggregating data held by multiple data providers. An example would be medical datasets, whereby ...

We investigate the required pulse duration for coherent supercontinuum generation for CEO detection in the 1-µm and 1.5-µm spectral regime. We demonstrate the first self-referenceable frequency comb from a gigahertz ...

This is an overview of the development and the applications of compact elastic backscatter depolarisation lidars. Two of such sensors are installed on-board the high-altitude research aircraft Myasishchev M-55 Geophysica. ...

We present an UAV compatible spectrometer designed for sampling air pollutants in remote locations. Relying on a custom-made Multi-Pass Cell and a 3-5 µm broadband supercontinuum light source, it takes advantage of an ...

Carrier envelope frequency (fCEO) stabilization of frequency combs is traditionally achieved via power modulation of the pump of the comb oscillator. A further possibility is to shift the laser fCEO using an external ...

Cesium-formamidinium-based mixed-halide perovskite materials with optical band gaps ranging from 1.5 to 1.8 eV are investigated by variable-angle spectroscopic ellipsometry. The determined complex refractive indices are ...
