Most digital security relies today on random numbers to generate cryptographic keys. Think of a cryptographic key like a long, complex password. If that password is truly random, an attacker has to ...

Even the most modern random number generators do not produce perfectly random numbers, which can be a problem for cryptographic applications. ETH Zurich researchers use entangled superconducting ...

Background Conventional coronary CT angiography (CCTA) is limited by calcium blooming and metallic artefacts, often reducing specificity in high-risk patients. Photon-counting CT (PCCT), with ...

Multi-source precipitation merging has been used for improving global precipitation estimation accuracy. However, current merging techniques heavily rely on gauge-based precipitation and/or streamflow ...

Introduction Dyslipidaemia is one of the established risk factors for cardiovascular disease. Evidence from large-scale trials showed that effective treatment of dyslipidaemia can reduce all-cause and ...

Propagating physical errors through a model is standard in the physical sciences, and yields a measure of predictive reliability (Taylor and Kuyatt, 1994; Bevington and Robinson, 2003; Vasquez and ...

Introduction For any health intervention, accurate knowledge of both benefits and harms is needed. Systematic reviews often compound poor reporting of harms in primary studies by failing to report ...
