objective(s):  medicinal benefits of quantum dots have been proved in recent years but there is little known about their toxicity especially in vivo toxicity. in order to use quantum dots in medical applications, studies ontheir in vivo toxicity is important.  materials and methods:cdse:zns quantum dots were injected in 10, 20, and 40 mg/kg doses to male mice10 days later, mice were sacrificed ...

quantitative structure-activity relationship (qsar) studies of a series of substituted 3-hydroxy-pyridine-4-ones and 3-hydroxy-pyran-4-ones as antibacterial and antifungal agents against a variety of microorganisms were performed. multiple linear regression approach was used as variable selection method. the antimicrobial activities of these compounds against staphylococcus aureus, aspergilus n...

A consistent quantum theory of polarization squeezed light formation in a inertial nonlinear medium is developed taking into account the response time of electronic Kerr nonlinearity. Stokes parameters are considered and their fluctuations spectra are investigated. It is established that the frequency at which the suppression of quantum fluctuations of Stokes parameters is the greatest can be c...

Quantum decoherence leads to non-unitary evolution of quantum systems and introduces noncontrollable aspects. For composite systems, the number of decoherence parameters always scales exponentially with the system size. In this work, we adopt a so-called compressive sensing technique to logarithmically reduce original data required to recover system dynamic process and reconstruct decoherence p...

The N-(2-benzoyl-phenyl) oxalyl derivatives are important models for studying of three-centered intramolecular hydrogen bonding in organic molecules. The quantum theoretical calculations for two crystal structures of N-(2-benzoyl-phenyl) oxalyl (compounds I and II) were performed by Density Functional Theory (B3LYP method and 6-311+G* basis set). From the optimized structures, geometric paramet...

Abstract: It is a well known fact that a quantum state |ψ(θ, φ)〉 is represented by a point on the Bloch sphere, characterized by two parameters θ and φ. In a recent work we already proved that it is impossible to partially swap these quantum parameters. Here in this work we will show that this impossibility theorem is consistent with principles like unitarity of quantum mechanics and no signall...

In this paper we optimize the experimental parameters to operate a Free Electron Laser with a laser wiggler in the Angstrom region. We show that the quantum regime of the Self Amplified Spontaneous Emission (Quantum SASE) may be reached with realistic parameters. The classical SASE regime is also discussed and compared with the quantum regime. PACS: 41.60.Cr; 42.50.Fx * e-mai address: rodolfob@...

By solving the Schrödinger equation one obtains the whole energy spectrum, both the bound and the continuum states. If the Hamiltonian depends on a set of parameters, these could be tuned to a transition from bound to continuum states. The behavior of systems near the threshold, which separates bound-states from continuum states, is important in the study of such phenomenon as: ionization of at...

Poincaré-invariant quantum field theories can be formulated on non-commutative planes if the coproduct on the Poincaré group is suitably deformed [1, 2].(See also especially Oeckl [3],[4] and Grosse et al.[5]) As shown in [6], this important result of these authors implies modification of free field commutation and anti-commutation relations and striking phenomenological consequences such as vi...
