The manipulation of digital content is not a new phenomenon, but the application of machine learning to the creation of deepfakes has (i) radically improved the quality of output, (ii) slashed the resources required to produce realistic fakes at previously ...

Fluorescence microscopy methods have been developed to circumvent the diffraction limit by exploiting nonlinearities in the interactions between light and fluorophores. Initially, these methods were up to orders of magnitude slower than standard microscopi ...
Running economy, known as the steady-state oxygen consumption at a given submaximal intensity, has been proposed as one of the key factors differentiating East African runners from other running communities around the world. Kenyan runners have dominated m ...
With the progress made in miniaturizing systems over the last decades, understanding materialsâ behavior at small scales has become a necessity.
In this context, glass behavior has remained largely unknown, partly for technological reasons and partly due ...
Chip-based optical waveguides formed by a silicon nitride (Si3N4) core and a silicon dioxide
(SiO2) cladding are an important platform for low loss waveguides and nonlinear optics.
High Q microresonators based on this material system have become a standard ...
In this paper an additive manufactured (AM) W-band monolithic feed chain is presented. The feed chain, which consists of a corrugated horn antenna and a turnstile orthomode transducer (OMT), operates over the entire W-band (75-110 GHz) and fulfills typical ...
