Time-reversal Characteristics of Quantum Normal Diffusion [PDF]

open access: yes, 2011
This paper concerns with the time-reversal characteristics of intrinsic normal diffusion in quantum systems. Time-reversible properties are quantified by the time-reversal test; the system evolved in the forward direction for a certain period is time ...

Observation of time-reversal symmetry breaking in the band structure of altermagnetic RuO2 [PDF]

open access: yesScience Advances, 2023
Altermagnets are an emerging elementary class of collinear magnets. Unlike ferromagnets, their distinct crystal symmetries inhibit magnetization while, unlike antiferromagnets, they promote strong spin polarization in the band structure.

Time-reversal symmetry-breaking charge order in a kagome superconductor [PDF]

open access: yesNature, 2021
The kagome lattice1, which is the most prominent structural motif in quantum physics, benefits from inherent non-trivial geometry so that it can host diverse quantum phases, ranging from spin-liquid phases, to topological matter, to intertwined orders2–8

Crystal time-reversal symmetry breaking and spontaneous Hall effect in collinear antiferromagnets [PDF]

open access: yesScience Advances, 2019
Identification of a previously overlooked spontaneous Hall effect mechanism creates opportunities in low-dissipation spintronics. Electrons, commonly moving along the applied electric field, acquire in certain magnets a dissipationless transverse ...

Charge reversal nano-systems for tumor therapy

open access: yesJournal of Nanobiotechnology, 2022
Surface charge of biological and medical nanocarriers has been demonstrated to play an important role in cellular uptake. Owing to the unique physicochemical properties, charge-reversal delivery strategy has rapidly developed as a promising approach for ...

Median clouds and a fast transposition median solver [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
The median problem seeks a permutation whose total distance to a given set of permutations (the base set) is minimal. This is an important problem in comparative genomics and has been studied for several distance measures such as reversals.

General Reversibility [PDF]

open access: yesElectronic Notes in Theoretical Computer Science, 2007
AbstractThe first and the second author introduced reversible CCS (RCCS) in order to model concurrent computations where certain actions are allowed to be reversed. Here we show that the core of the construction can be analysed at an abstract level, yielding a theorem of pure category theory which underlies the previous results.

Loss of physical reversibility in reversible systems [PDF]

open access: yesPhysica D: Nonlinear Phenomena, 2020
A dynamical system is said to be reversible if, given an output, the input can always be recovered in a well-posed manner. Nevertheless, we argue that reversible systems that have a time-reversal symmetry, such as the Nonlinear Schr{ }dinger equation and the $ ^4$ equation can become "physically irreversible".

Sapitinib Reverses Anticancer Drug Resistance in Colon Cancer Cells Overexpressing the ABCB1 Transporter

open access: yesFrontiers in Oncology, 2020
The efficacy of anti-cancer drugs in patients can be attenuated by the development of multi-drug resistance (MDR) due to ATP-binding cassette (ABC) transporters overexpression.

Reversal of Azithromycin Resistance in Staphylococcus saprophyticus by Baicalin

open access: yesFrontiers in Veterinary Science, 2022
In recent years, the efficacy of antibiotics has been threatened by the evolution of bacterial resistance. We previously demonstrated that baicalin (Bac) showed synergies with azithromycin (Azm) against Azm-resistant Staphylococcus saprophyticus (ARSS ...
