A Comparative Study of Syntactic Hypotaxis and Parataxis in English and Chinese From the Aesthetic Perspective of Classical Painting
Parataxis is the main grammatical feature of Chinese sentences while hypotaxis is the main grammatical feature of English. Similarly, Chinese classical paintings stress on the psychological harmony of subject-object unity and Western classical paintings on extrinsic form. It is found that the aesthetic thinking of classical painting is reflected in English and Chinese syntactic structure
Universal Thermoelectric Effect of Dirac Fermions in Graphene
We numerically study the thermoelectric transports of Dirac fermions in
graphene in the presence of a strong magnetic field and disorder. We find that
the thermoelectric transport coefficients demonstrate universal behavior
depending on the ratio between the temperature and the width of the
disorder-broadened Landau levels(LLs). The transverse thermoelectric
conductivity reaches a universal quantum value at the center of
each LL in the high temperature regime, and it has a linear temperature
dependence at low temperatures. The calculated Nernst signal has a peak at the
central LL with heights of the order of , and changes sign near other
LLs, while the thermopower has an opposite behavior, in good agreement with
experimental data. The validity of the generalized Mott relation between the
thermoelectric and electrical transport coefficients is verified in a wide
range of temperatures.Comment: 4 pages, 4 figures, published versio
Effects of losses in the hybrid atom-light interferometer
Enhanced Raman scattering can be obtained by injecting a seeded light field
which is correlated with the initially prepared collective atomic excitation.
This Raman amplification process can be used to realize atom-light hybrid
interferometer. We numerically calculate the phase sensitivities and the
signal-to-noise ratios of this interferometer with the method of homodyne
detection and intensity detection, and give their differences between this two
methods. In the presence of loss of light field and atomic decoherence the
measure precision will be reduced which can be explained by the break of the
intermode decorrelation conditions of output modesComment: 9 pages, 7 figure
4-Chloro-5-[(5,5-dimethyl-4,5-dihydroisoxazol-3-yl)sulfonylmethyl]-3-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole
The molecule of the title compound, C12H15ClF3N3O3S, is twisted, as indicated by the C—S—C—C torsion angle of 66.00 (18)° for the atoms linking the ring systems. An intramolecular C—H⋯F short contact occurs. In the crystal, non-classical C—H⋯O interactions, one of which has a short H⋯O contact of 2.28 Å, link the molecules
Tris[tris(1,10-phenanthroline-κ2 N,N′)iron(II)] dodecatungstoferrate dihydrate
The title compound, [Fe(C12H8N2)3]3[FeW12O40]·2H2O, was prepared under hydrothermal conditions. The discrete Keggin-type [FeW12O40]6− heteropolyoxoanion has threefold symmetry, with the FeII atom located on the threefold rotation axis. The central FeO4 tetrahedron in the anion shares its O atoms with four W3O13 trinuclear units, each of which is made up of three edge-shared WO6 octahedral units. The FeII atom in the complex cation, viz [Fe(phen)3]2+ (phen is 1,10-phenanthroline), shows a slightly distorted octahedral geometry defined by six N atoms from three phen ligands. The polyoxoanions pack together with the cations, with the disordered water molecules located in voids; the site occupancy factor for each water O atom is 0.33
