The Stepped Wedge Cluster Randomized Trial is a research methodology that has been growing in popularity, particularly for pragmatic implementation and dissemination trials. SW-CRTs can have advantages over parallel cluster randomized trials with regards to statistical power.

The astronomers’ goal: find an artificial intelligence algorithm to interpret microlensing events captured by the upcoming Roman Space Telescope and speed detection of exoplanets around other stars. They achieved that, but the AI told them something unexpected and deep: the theory used to infer stellar and exoplanetary masses and orbits from observations was incomplete. Digging into the mathematics, they uncovered a theory that explains all types of microlensing events and possible ambiguities in interpreting them.

Insider threats are one of the top security concerns facing large organizations. Current and former employees, business partners, contractors—anyone with the right level of access to a company’s data—can pose a threat. The incidence of insider threats has increased in recent years, at a significant cost to companies. Jingrui He, associate professor in the School of Information Sciences at the University of Illinois Urbana-Champaign, has been awarded a three-year, $200,000 grant from the C3.ai Digital Transformation Institute for a new project that seeks to detect and predict insider threats.

Researchers at the Advanced Quantum Testbed at Berkeley Lab demonstrated the first three-qubit high-fidelity iToffoli native gate in a superconducting quantum information processor and in a single step. This demonstration adds a novel easy-to-implement native three-qubit logic gate for universal quantum computing.

Argonne researchers have used quantum computers to simulate spin defects, an important material property for the next generation of quantum computers.
When reading news and analyses of the Russian invasion of Ukraine, researchers in Spain perceived many conflicting messages being transmitted. The most notable one is the theory of “two Ukraines” or the existence of ideologically pro-West and pro-Russian regions. This doesn’t match the unity of Ukrainians against the Russian invasion, so they wondered if they could provide any solid proof to support or reject such a theory via data analysis tools?
