Superconductivity is a unique manifestation of quantum mechanics on a macroscopic scale, and one of the rare examples of many-body phenomena that can be explained by predictive, quantitative theories. The superconducting ground state is described as a condensate of Cooper pairs, and a major challenge has been to understand which mechanisms could lead to a bound state between two electrons, desp...

Although African Americans were generally underincluded in previous research studies, new and growing evidence suggests that they may be at increased risk of the disease and that they di...

The definition of IND-CCA disallows an adversary from querying the challenge ciphertext to its decryption oracle. We point out that there are several ways to formalize this. We show that, surprisingly, for public-key encryption the resulting notions are not all equivalent. We then consider the same question for key-encapsulation mechanisms (KEMs) and show that in this case the four notions are ...

Demyelinating syndrome (DS) is a rare manifestation of systemic lupus erythematosus (SLE) (1%) with high clinical heterogeneity and potentially severe prognosis. It can represent a diagnostic and therapeutic challenge for clinicians. A recent study described 5 different patterns of demyelinating disease presentation, characterised by specific clinical, laboratory and brain and spine magnetic re...
