The arrow of bioimpedance [PDF]

open access: yesKidney International, 2006
The value of bioimpedance in hemodialysis remains under debate. However, when appropriately used, bioimpedance can provide measures of body hydration characterized by a small error, a high sensitivity to changes in water volume, and, above all, a linear relationship over a wide range of volume changes. These features make it very useful to measure body

Arrow of Time for Continuous Quantum Measurement. [PDF]

open access: yesPhysical Review Letters, 2016
We investigate the statistical arrow of time for a quantum system being monitored by a sequence of measurements. For a continuous qubit measurement example, we demonstrate that time-reversed evolution is always physically possible, provided that the ...

The Importance of Boundary Conditions in Quantum Mechanics [PDF]

open access: yes, 2003
We discuss the role of boundary conditions in determining the physical content of the solutions of the Schrodinger equation. We study the standing-wave, the ``in,'' the ``out,'' and the purely outgoing boundary conditions. As well, we rephrase Feynman's $

Time's arrow, time's cycle: Granulite metamorphism and geodynamics

open access: yesMineralogical magazine, 2019
Although the thermal evolution of the mantle before c. 3.0 Ga remains unclear, since c. 3.0 Ga secular cooling has dominated over heat production—this is time's arrow.

Comparison of headspace–SPME and SPME-Arrow–GC–MS methods for the determination of volatile compounds in Korean salt–fermented fish sauce

open access: yesApplied Biological Chemistry, 2019
A new solid phase microextraction (SPME)-Arrow method was evaluated for the analysis of volatile compounds in kanari-aekjeot, a Korean traditional salt–fermented sand lance sauce, and compared it to the standard headspace–SPME method. Factors observed to
