Recent developments in classical density functional theory: Internal energy functional and diagrammatic structure of fundamental measure theory [PDF]

open access: yesCondensed Matter Physics, 2012
An overview of several recent developments in density functional theory for classical inhomogeneous liquids is given. We show how Levy's constrained search method can be used to derive the variational principle that underlies density functional theory ...

Algorithmic Randomness and Capacity of Closed Sets [PDF]

open access: yesLogical Methods in Computer Science, 2011
We investigate the connection between measure, capacity and algorithmic randomness for the space of closed sets. For any computable measure m, a computable capacity T may be defined by letting T(Q) be the measure of the family of closed sets K which have

How Quantum Mechanics Requires Non-Additive Measures

open access: yesEntropy, 2023
Measure theory is used in physics, not just to capture classical probability, but also to quantify the number of states. In previous works, we found that state quantification plays a foundational role in classical mechanics, and, therefore, we set ...

The Concise Health Risk Tracking ‐ Self‐Report (CHRT‐SR)—A measure of suicidal risk: Performance in adolescent outpatients

open access: yesInternational Journal of Methods in Psychiatric Research, 2023
Objectives The Concise Health Risk Tracking Self‐Report (CHRT‐SR) assesses the risk of suicidal behavior. We report its psychometric properties in a representative sample of adolescent outpatients. Methods A sample (n = 657) of adolescents (

The 19-Item Environmental Knowledge Test (EKT-19): A short, psychometrically robust measure of environmental knowledge

open access: yesHeliyon, 2023
Environmental knowledge is considered an important pre-cursor to pro-environmental behaviour. Though several tools have been designed to measure environmental knowledge, there remains no concise, psychometrically grounded measure.

A new entropic quantum correlation measure for adversarial systems

open access: yesScientific Reports, 2023
Quantum correlation often refers to correlations exhibited by two or more local subsystems under a suitable measurement. These correlations are beyond the framework of classical statistics and the associated classical probability distribution.

Measurement theory in classical mechanics [PDF]

open access: yesProgress of Theoretical and Experimental Physics, 2020
Abstract We investigate measurement theory in classical mechanics in the formulation of classical mechanics by Koopman and von Neumann (KvN), which uses Hilbert space. We show a difference between classical and quantum mechanics in the “relative interpretation” of the state of the target of measurement and the state of the measurement ...

Explicitly stable fundamental-measure-theory models for classical density functional theory [PDF]

open access: yesPhysical Review E, 2020
The derivation of the state of the art tensorial versions of Fundamental Measure Theory (a form of classical Density Functional Theory for hard spheres) are re-examined in the light of the recently introduced concept of global stability of the density functional based on its boundedness (Lutsko and Lam, Phys. Rev. E 98, 012604 (2018)). It is shown that

Visualizing Items and Measures: An Overview and Demonstration of the Kernel Smoothing Item Response Theory Technique [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2020
The current demonstration was conducted to familiarize a broader audience of applied researchers in psychology and social sciences with the benefits of an exploratory psychometric technique -- kernel smoothing item response theory (KSIRT). A data-driven,

Shear viscosity of the $\Phi^4$ theory from classical simulation [PDF]

open access: yes, 2015
Shear viscosity of the classical $\Phi^4$ theory is measured using classical microcanonical simulation. To calculate the Kubo formula, we measure the energy-momentum tensor correlation function, and apply the Green-Kubo relation. Being a classical theory,
