Contact electrification (CE), the transfer of charge between two surfaces that are brought into contact and then separated, plays a central role in several useful technologies, such as photocopying, laser printing, and electrostatic separation methods, but is also responsible for the build-up of charge leading to electrical shocks, explosions, mechanical jams, or damage of electronic equipment....
Social media sites such as Facebook are thought to act as a platform for narcissistic behavior, such as posting self-promoting status updates or attractive photos. Narcissism is identifiable via social media, and it has been associated with negative peer appraisals. This article presents three studies with undergraduate students that examined the interpersonal implications of narcissism on Face...
It is well-known that some metals/alloys are sensitizing on skin contact, but it is not so well appreciated that sensitization is dependent on the reaction of the metal/alloy with sweat. The first step in skin sensitization by metals/alloys is a corrosion process and the formation of soluble metal ions. The nature of this process has implications with respect to occurrence of metal contact derm...
We consider electron spin qubits in quantum dots and define a measurement efficiency e to characterize reliable measurements via n-shot readouts. We propose various implementations based on a double dot and a quantum point contact (QPC) and show that the associated efficiencies e vary between 50% and 100%, allowing single-shot readout in the latter case. We model the readout microscopically and...

BACKGROUND Many countries have amassed antiviral stockpiles for pandemic preparedness. Despite extensive trial data and modelling studies, it remains unclear how to make optimal use of antiviral stockpiles within the constraints of healthcare infrastructure. Modelling studies informed recommendations for liberal antiviral distribution in the pandemic phase, primarily to prevent infection, but f...
