The Copenhagen interpretation is an interpretation of quantum mechanics formulated mainly by Niels Bohr and also Werner Heisenberg while collaborating in Copenhagen. According to a poll in 1997, the Copenhagen interpretation is the most widely-accepted interpretation of quantum mechanics [1] and it was the first general attempt to understand the world of atoms. Since Copenhagen Interpretation w...

Motivated by Segal’s axiom of conformal field theory, we do a survey on geometrical random fields. We do a history of continuous random fields in order to arrive at a field theoretical analog of Klauder’s quantization in Hamiltonian quantum mechanic by using infinite dimensional Airault-Malliavin Brownian motion. AMS 2000 subject classifications: Primary 60G60; secondary 81T40.

Naphthoquinones are natural aromatic compounds that can be discovered in various plant families. In recent times a diversity of biological activities of these compounds has been reported. In most cases, these pharmacological activities are related to redox and acid-base properties, which can be modulated synthetically by modifying the substituents attached to the 1, 4- naphthoquinone ring, in o...

The syntheses of novel hydrazono acyclic nucleosides similar to miconazole scaffolds are described. In this series of acyclic nucleosides, pyrimidine as well as purine and other azole derivatives replaced the imidazole function in miconazole and the ether group was replaced with a hydrazone moiety using phenylhydrazine. To interpret the dominant formation of (E)-hydrazone derivatives rather tha...

The asymmetric unit of the title compound,  Contains two independent molecules. The Cu atoms are four coordinated in distorted tetrahedral configuration by two atoms from 5,5`-dimethyl-2,2`- bipyridine and two terminal atoms. In the Cuystal structure, inter molecular hydrogen bonds link the molecules. The are  contacts between the methyl groups and the pyridine and five member rings containing ...

OBJECTIVES To describe the population of aged as compared to young patients under mechanical ventilation and to analyze the mortality risk factors of this group in an intensive care unit. METHODS This was a prospective observational trial in patients over 18 years of age, admitted in an intensive care unit and under mechanical ventilation, during one year. Patients were divided into two group...

We propose a covariant algorithm for relativistic ideal measurements and for relativistic continuous measurements, its non-relativistic limit results the algorithm of the Event-Enhanced Quantum Theory. Therefore an additional intrinsic parameter, the proper time, is used. As an application we compute the time of arrival of a particle at a detector and find good agreement between the expected va...

Quantum dynamics of driven open systems should be compatible with both quantum mechanic and thermodynamic principles. By formulating the principles in terms a set postulates we obtain thermodynamically consistent master equation. Following an axiomatic approach, base analysis on autonomous description, incorporating drive as large transient control system. In appropriate physical limit, derive ...
