Using suspension-cultured Acer pseudoplatanus cells requiring 2,4-dichlorophenoxyacetic acid for growth, the dependence of the population doubling time and the maximum increase in cell population density on the auxin concentration was studied. It appears that in the range of 2,4-dichlorophenoxyacetic acid concentration from 4 x 10(-8) to 4 x 10(-6) M, the rate of cell division during the logari...

The amount and distribution over the active area of current density produced by stack is a key aspect fuel cell performance. performance proton exchange membrane (PEMFC) affected many factors, including operating conditions, flow field manifold design, In present study, 3D multiphysics model PEMFC half-cell focused in cathode side developed. Statistical analysis tools are proposed to quantitati...

Comprehensive understanding of the long-term trends and seasonality of water quality is important for controlling water pollution. This study focuses on spatio-temporal distributions, long-term trends, and seasonality of water quality in the Yangtze River basin using a combination of the seasonal Mann-Kendall test and time-series decomposition. The used weekly water quality data were from 17 en...

A system of two static quarks, at fixed distances r, and two light quarks is studied on an anisotropic lattice. Excitations by operators emphasizing quark or gluon degrees of freedom are examined. The maximum entropy method is applied in the spectral analysis. These simulations ultimately aim at learning about mechanisms of hadronic interaction.

We summarize the performance of the MAX experiment during its 5 years of operation and present a compilation of the results to date. We describe MAXIMA, a balloon borne experiment employing an array of detectors in the focal plane, that will provide sensitive measurements of the power spectrum between l ∼ 60 and l ∼ 650.

We present an operational approach to address the in-medium behavior of charmonium and analyze the reliability of maximum entropy method (MEM). We study the dependences of the ratio of correlators to the reconstructed one and the free one on the resonance’s width and the continuum’s threshold. Furthermore, we discuss the issue of the default model dependence of the spectral function obtained fr...

It is known that one-dimensional Dirac systems with potentials q which tend to −∞ (or ∞) at infinity, such that 1/q is of bounded variation, have a purely absolutely continuous spectrum covering the whole real line. We show that, for the system on a half-line, there are no local maxima of the spectral density (points of spectral concentration) above some value of the spectral parameter if q sat...

The electron density function, Q(r), in a crystal determines its diffraction pattern, i.e. both the magnitudes and phases of its x-ray diffraction maxima, and conversely. If, however, as is always the case, only magnitudes are available from the diffraction experiment, then the density function ρ(r) cannot be recovered. If one invokes prior structural knowledge, usually that the crystal is comp...

In 1990 Sakata and Sato applied the maximum entropy method (MEM) to a set of structure factors measured earlier by Saka and Kato with the Pendellosung method. They found the presence of non-nuclear attractors, i.e., maxima in the density between two bonded atoms. We applied the MEM to a limited set of Fourier data calculated from a known electron density distribution (EDD) of silicon. The EDD o...
