The Physical Meaning Of The Wavefunction II
"... Abstract: The hottest and one of the major unresolved problems of today’s quantum mechanics is the physical meaning of the wave function. The debate about the physical meaning of the wave function raises broader issues as well. In brief, the difficulties stemmed from an apparent conflict about the e ..."

The Physical Meaning Of The Wavefunction
"... Abstract: Under some welldefined conditions the mathematical formalism of quantum mechanics enables physicists, chemists and other to calculate and predict the outcome of a vast number of experiments. In fact, especially the Schrödinger equation which involves an imaginary quantity describes how a ..."

quantum state of a physical system changes with time and is one of the main pillars of modern quantum mechanics. The wave function itself is a determining part of the Schrödinger equation, but the physical meaning of the wave function is still not clear. Altogether, does the wave function represent a new

 IEEE Trans. Inf. Theory,
, 1976
"... Abstract Two kinds of contemporary developments in crypcommunications over an insecure channel order to use cryptogtography are examined. Widening applications of teleprocessraphy to insure privacy, however, it currently necessary for the ing have given rise to a need for new types of cryptograph ..."

cryptographic unrealistic to expect initial business contacts to be postponed problems of long standing. long enough for keys to be transmitted by some physical means. The cost and delay imposed by this key distribution problem is a major barrier to the transfer of business communications
The Physical Meaning of Fermi Coordinates
, 1994
"... Fermi coordinates (FC) are supposed to be the natural extension of Cartesian coordinates for an arbitrary moving observer in curved spacetime. Since their construction cannot be done on the whole space and even not in the whole past of the observer we examine which construction principles are respo ..."

by Rindler for the outer region of Kruskal space and the Rindler wedge. In perturbational approaches the modification leads also to different predictions for certain physical systems. As an example we consider atomic interferometry and derive the deviation of the accelerationinduced phase shift from
The Physical Meaning of Gauge Transformations
, 2006
"... The structure of classical electrodynamics based on the variational principle together with causality and spacetime homogeneity is analyzed. It is proved that in this case the 4potentials are defined uniquely. On the other hand, the approach where Maxwell equations and the Lorentz law of force are ..."

are regarded as cornerstones of the theory allows gauge transformations. For this reason, the two theories are not equivalent. A simple example substantiates this conclusion. Quantum physics is linked to the variational principle and it is proved that the same result holds for it. The compatibility
On the physical meaning of the ZORA Hamiltoniany
, 2003
"... By expanding the Foldy–Wouthuysen representation of the Dirac equation near the freeparticle solution it is shown that the Hamiltonian of the zerothorder regular approximation (ZORA) leads to an infinite summation of the leading relativistic corrections to the freeparticle, nonrelativistic energ ..."

of physical problems. ZORA is analogous to the random phase approximation in manybody theory in the sense that both methods include an infiniteorder summation of the asymptotically nonvanishing terms. This highlights the difference between ZORA and the Douglas–Kroll method, with the latter being analogous
Graphical models, exponential families, and variational inference
, 2008
"... The formalism of probabilistic graphical models provides a unifying framework for capturing complex dependencies among random variables, and building largescale multivariate statistical models. Graphical models have become a focus of research in many statistical, computational and mathematical fiel ..."

Activity recognition from userannotated acceleration data
, 2004
"... In this work, algorithms are developed and evaluated to detect physical activities from data acquired using five small biaxial accelerometers worn simultaneously on different parts of the body. Acceleration data was collected from 20 subjects without researcher supervision or observation. Subjects ..."
