An MCHF atomic-structure package is presented based on dynamic memory allocation, sparse matrix methods, and a recently developed angular library. It is meant for large-scale calculations in a basis of orthogonal orbitals for groups of LS terms of arbitrary parity. For Breit-Pauli calculations, all operators – spin-orbit, spin-other orbit, spin-spin, and orbit-orbit – may be included. For trans...

The synthesis of write-ahead logging has developed redundancy, and current trends suggest that the investigation of the Ethernet will soon emerge. Given the current status of clientserver models, cyberneticists predictably desire the construction of systems, which embodies the confirmed principles of theory [114, 114, 188, 62, 70, 62, 179, 68, 95, 68, 54, 152, 191, 114, 59, 168, 148, 54, 99, 58...

An introduction is given to an algebraic formulation and generalisation of the consistent histories approach to quantum theory. The main technical tool in this theory is an orthoalgebra of history propositions that serves as a generalised temporal analogue of the lattice of propositions of standard quantum logic. Particular emphasis is placed on those cases in which the history propositions can...

We elaborate on the distinction between geometric and dynamical phase in quantum theory and we show that the former is intrinsically linked to the quantum mechanical probabilistic structure. In particular, we examine the appearance of the Berry phase in the consistent histories scheme and establish that it is the basic building block of the decoherence functional. These results are consequences...

In designing structured P2P networks, scalability, resilience, and load balancing are features that are needed to be handled meticulously. The P2P overlay has to handle large scale of nodes while maintaining minimized path lengths in performing lookups. It has also to be resilient to nodes’ failure and be able to distribute the load uniformly over its participant. In this paper, we introduce SH...

This paper answers Bell’s question: What does quantum information refer to? It is about quantum properties represented by subspaces of the quantum Hilbert space, or their projectors, to which standard (Kolmogorov) probabilities can be assigned by using a projective decomposition of the identity (PDI or framework) as a quantum sample space. The single framework rule of consistent histories preve...

This paper is an answer to the preceding paper by Kastner, in which she continued the criticism of the counterfactual usage of the Aharonov ± Bergman ± Lebowitz rule in the framework of the time-symmetrized quantum theory, in particular, by analyzing the three-box `̀ paradox .’ ’ It is argued that the criticism is not sound . Paradoxical features of the three-box example are discussed. It is exp...

The argument of Einstein, Podolsky and Rosen (EPR), advanced by these authors in support of the thesis that quantummechanics cannot provide a complete description of a physical system, has been receiving close attention in foundational studies and debates on quantum mechanics ever since the famous paper of EPR appeared in 1935 [1]. Not lacking in subtlety, the EPR argument was bound to be misre...
