Black-Hole Uncertainty Entails an Intrinsic Time Arrow. a Note on the Hawking-Penrose Controversy [PDF]

, 1999
Any theory that states that the basic laws of physics are time-symmetric must be strictly deterministic. Only determinism enables time reversal of entropy increase. A contradiction therefore arises between two statements of Hawking.

Theory for nucleation at an interface and magnetization reversal of a two-layer nanowire [PDF]

, 2006
Nucleation at the interface between two adjoining regions with dissimilar physical properties is investigated using a model for magnetization reversal of a two-layer ferromagnetic nanowire.

Reversal of direct oral anticoagulants: Guidance from the Anticoagulation Forum

American journal of hematology/oncology, 2019
Two specific reversal agents for direct oral anticoagulants (DOACs) have been approved in the United States: idarucizumab for dabigatran reversal and andexanet alfa for apixaban and rivaroxaban reversal.

Possible realization of directional optical waveguides in photonic crystals with broken time-reversal symmetry. [PDF]

Physical Review Letters, 2005
We show how, in principle, to construct analogs of quantum Hall edge states in "photonic crystals" made with nonreciprocal (Faraday-effect) media. These form "one-way waveguides" that allow electromagnetic energy to flow in one direction only.

Fast magnetization reversal of nanoclusters in resonator

, 2012
An effective method for ultrafast magnetization reversal of nanoclusters is suggested. The method is based on coupling a nanocluster to a resonant electric circuit.

Andexanet Alfa for the Reversal of Factor Xa Inhibitor Activity.

New England Journal of Medicine, 2015
BACKGROUND Bleeding is a complication of treatment with factor Xa inhibitors, but there are no specific agents for the reversal of the effects of these drugs. Andexanet is designed to reverse the anticoagulant effects of factor Xa inhibitors.

Theta, time reversal and temperature [PDF]

, 2017
A bstractSU(N ) gauge theory is time reversal invariant at θ = 0 and θ = π. We show that at θ = π there is a discrete ’t Hooft anomaly involving time reversal and the center symmetry. This anomaly leads to constraints on the vacua of the theory.

Is perpendicular magnetic anisotropy essential to all-optical ultrafast spin reversal in ferromagnets?

, 2017
All-optical spin reversal presents a new opportunity for spin manipulations, free of a magnetic field. Most of all-optical-spin-reversal ferromagnets are found to have a perpendicular magnetic anisotropy (PMA), but it has been unknown whether PMA is ...

Unveiling Magnetic Dipole Radiation in Phase-Reversal Leaky-Wave Antennas [PDF]

, 2013
The radiation principle of travelling-wave type phase-reversal antennas is explained in details, unveiling the presence of magnetic-dipole radiation in addition to well-known electric dipole radiation.
