Kirkwood discovered in 1933, and Dirac 1945, a representation of quantum states that has undergone renaissance recently. The Kirkwood-Dirac (KD) distribution been employed to study nonclassicality across physics, from metrology chaos the foundations theory. KD is quasiprobability distribution, generalization probability which can behave nonclassically by having negative or nonreal elements. Neg...

The authors study a validity timescale of the discrete truncated Wigner approximation for several quantum-spin systems with long-range interactions step-function form by using Bogoliubov-Born-Green-Kirkwood-Yvon equation.

By means of molecular dynamics simulations, dynamical properties of racemic ibuprofen glass-forming liquid are investigated at different temperatures from 360 to 500 K. The origin of the peculiar low amplitude Debye-type relaxation observed experimentally by dielectric relaxation spectroscopy is addressed (Bras, A. R.; Noronha, J. P.; Antunes, A. M. M.; Cardoso, M. M.; Schonhals, A.; Affouard, ...

The paper explores preliminary data of four cases in a larger study investigating the effects on learning of a new educational technology called Media Annotation Tool (MAT). In particular, the paper focuses on learning engagement with MAT and begins to raise questions about what factors promote or enhance engagement. Drawing on the work of Kirkwood (2009), the authors analyse the type of educat...

The stabilizing free energy of ß-trypsin was determined by hydrogen ion titration. In the pH range from 3.0 to 7.0, the change in free energy difference for the stabilization of the native protein relative to the unfolded one (∆∆G0 titration) was 9.51 ± 0.06 kcal/mol. An isoelectric point of 10.0 was determined, allowing us to calculate the Tanford and Kirkwood electrostatic factor w. This fact...
