Abstract Coarse geometry, and in particular coarse homotopy theory, has proven to be a powerful tool for approaching problems geometric group theory higher index theory. In this paper,we continue develop area by proving Lifting Lemma with respect certain class of bornologous surjective maps. This is wide enough include quotients coarsely discontinuous actions, which allows us obtain results con...

A strong interaction between light and a magnet can produce a hybrid system with energy levels distinct from either the light or the magnet on its own. In this “strong coupling” regime, quantum information can be easily transferred from the light to the magnet and vice versa. This feature could be useful in quantum information technologies or as a way to use one component (say, the light) to pr...

Magnetization of large Nd-Fe-B sintered permanent magnets is still challenging. This type of permanent magnet is electrically conductive, so impulse magnetization causes a flow of eddy currents which prevent magnetization of the whole volume of the magnet. The paper deals with the impulse magnetization of sintered Nd-Fe-B permanent magnets and shows a method for the determination of suitable pa...

Ferrite magnets have a long history. They are used in motors, magnetic fluids, drug delivery systems, etc. Herein we report a mesoscopic ferrite bar magnet based on rod-shaped ε-Fe2O3 with a large coercive field (>25 kOe). The ε-Fe2O3-based bar magnet is a single crystal with a single magnetic domain along the longitudinal direction. A wide frequency range spectroscopic study shows that the cry...

Bat exposures account for a quarter of the human rabies treatments in New York and a large share of the annual prophylaxis costs of US$1.8 million. To reduce the number of treatments associated with bats that are not captured and tested for rabies, the authors developed a refrigerator magnet to advise residents to consider the risk of rabies exposure from bat encounters, and a sticker to warn c...

We report a retrospective case of inner magnet migration, which occurred after 1.5 Tesla MRI scanning in an adult recipient of a bilateral cochlear implant (CI) despite a focused head dressing. The patient, bilaterally implanted with Nucleus 5 CIs (Cochlear LTD, Sydney, Australia), underwent a 1.5 Tesla cholangio-MRI scan for biliary duct pathology. In subsequent days, a focal skin alteration a...
