On obtaining classical mechanics from quantum mechanics [PDF]

, 2006
Constructing a classical mechanical system associated with a given quantum mechanical one, entails construction of a classical phase space and a corresponding Hamiltonian function from the available quantum structures and a notion of coarser observations.

Assassins, Gods, and Androids: How Narratives and Game Mechanics Shape Eudaimonic Game Experiences

Media and Communication, 2021
Emerging research has suggested that digital games can generate entertainment experiences beyond hedonic enjoyment towards eudaimonic experiences: Being emotionally moved, stimulated to reflect on one’s self or a sense of elevation.

Research on the Corrosion/Permeability/Frost Resistance of Concrete by Experimental and Microscopic Mechanisms Under Different Water–Binder Ratios

International Journal of Concrete Structures and Materials, 2020
To study the influence of different water–binder ratios on the corrosion, permeability, and freezing properties of concrete, we produced different strengths of concrete with respective water–binder ratios of 0.32, 0.38, 0.50, and 0.66.

Activation effects on the physical characteristics of T lymphocytes

Frontiers in Bioengineering and Biotechnology, 2023
The deformability of leukocytes is relevant to a wide array of physiological and pathophysiological behaviors. The goal of this study is to provide a detailed, quantitative characterization of the mechanical properties of T cells and how those properties

Nambu Quantum Mechanics: A Nonlinear Generalization of Geometric Quantum Mechanics [PDF]

, 2002
We propose a generalization of the standard geometric formulation of quantum mechanics, based on the classical Nambu dynamics of free Euler tops. This extended quantum mechanics has in lieu of the standard exponential time evolution, a nonlinear temporal

Computer Simulations in Mechanics at the Secondary School

Informatics in Education, 2004
Computer simulations seem to be one of the most effective ways to use computers in physics education. They encourage students to carry out the processes used in physics research: to question, predict, hypothesise, observe, interpret results etc.
