Superposition principle applies to human walking with two simultaneous interventions

open access: yesScientific Reports, 2021
Gait rehabilitation therapies provide adjusted sensory inputs to modify and retrain walking patterns in an impaired gait. Asymmetric walking is a common gait abnormality, especially among stroke survivors.

Spontaneous symmetry breaking and superposition of states in systems with dynamic chaos

open access: yesPhysics of Complex Systems, 2021
The article discusses one of the typical problems described by the equations of nonlinear dynamics—forced oscillations in a system with W-potential. It focuses, in particular, on chaotic oscillations in the presence of dissipation. In this case the state

The Pure State Space of Quantum Mechanics as Hermitian Symmetric Space [PDF]

open access: yes, 2002
The pure state space of Quantum Mechanics is investigated as Hermitian Symmetric Kaehler manifold. The classical principles of Quantum Mechanics (Quantum Superposition Principle, Heisenberg Uncertainty Principle, Quantum Probability Principle) and ...

The Superposition Principle of Waves Not Fulfilled under M. W. Evans' O(3) Hypothesis [PDF]

open access: yes, 2006
In 1992 M.W. Evans proposed a so-called O(3) symmetry of electromagnetic fields by adding a constant longitudinal "ghost field" to the well-known transversal plane em waves. He considered this symmetry as a new law of electromagnetics.

The theory of calculation of reinforced concrete structures and the principles of the Eurocode

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2021
The theory of calculating reinforced concrete is analyzed. As we known reinforced concrete with enormous volumes of application and huge financial costs, due to the great complexity of its nonlinear properties, has a surprisingly unscientific theory of ...

Does gravity induce wavefunction collapse? An examination of Penrose's conjecture [PDF]

open access: yes, 2013
According to Penrose, the fundamental conflict between the superposition principle of quantum mechanics and the principle of general covariance of general relativity entails the existence of wavefunction collapse, e.g.

Linear Superposition as a Core Theorem of Quantum Empiricism

open access: yesUniverse, 2022
Clarifying the nature of the quantum state |Ψ⟩ is at the root of the problems with insight into counter-intuitive quantum postulates. We provide a direct—and math-axiom free—empirical derivation of this object as an element of a vector space ...

Characterizing the superposition of arbitrary random quantum states and a known quantum state

open access: yesResults in Physics, 2023
The superposition of states is one of the most fundamental issues in the quantum world. Generally there do not exist physical operations to superpose two unknown random states with nonzero probability.

Superposition principle and schemes for measure differential equations [PDF]

open access: yesKinetic and Related Models, 2019
Measure Differential Equations (MDE) describe the evolution of probability measures driven by probability velocity fields, i.e. probability measures on the tangent bundle. They are, on one side, a measure-theoretic generalization of ordinary differential

Time-moisture superposition principle in creep behavior of white oak with various earlywood vessel locations

open access: yesMaderas: Ciencia y Tecnología, 2023
Creep behavior of wood plays a fundamental role in precision processing of wood. In this work, experimental creep tests have been conducted to determine the influence of earlywood vessel location and moisture content on creep behavior of white oak ...
