Logistics Data Exchange for the EDI Customs Clearance System based on XML
Because of the disconnection between the Logistics services trading platform and the EDI customs clearance system, the logistics clearance data needed to be gathered manually, and the efficiency of customs clearance was rather low. In view of this problem, a logistics data exchange method based on the XML technology was proposed, which firstly achieved the batch extraction and conversion of the logistics clearance data that came from the Logistics services trading platform. Then, the data was transferred to the customs broker. Finally, the data was parsed by deserialization and submitted to the EDI customs clearance system automatically. The logistics data exchange method achieved the connection between the logistics services trading platform and the EDI customs clearance system, and raised the efficiency of customs clearance
Magnetic field switching in parallel quantum dots
We show that the Coulomb blockade in parallel dots pierced by magnetic flux
completely blocks the resonant current for any value of except
for integer multiples of the flux quantum . This non-analytic
(switching) dependence of the current on arises only when the dot states
that carry the current are of the same energy. The time needed to reach the
steady state, however, diverges when .Comment: additional explanations added, Europhysics Letters, in pres
Spectral and optical properties in the antiphase stripe phase of the cuprate superconductors
We investigate the superconducting order parameter, the spectral and optical
properties in a stripe model with spin (charge) domain-derived scattering
potential (). We show that the charge domain-derived scattering
is less effective than the spin scattering on the suppression of
superconductivity. For , the spectral weight concentrates on
the () antinodal region, and a finite energy peak appears in the optical
conductivity with the disappearance of the Drude peak. But for , the spectral weight concentrates on the () nodal region,
and a residual Drude peak exists in the optical conductivity without the finite
energy peak. These results consistently account for the divergent observations
in the ARPES and optical conductivity experiments in several high-
cuprates, and suggest that the "insulating" and "metallic" properties are
intrinsic to the stripe state, depending on the relative strength of the spin
and charge domain-derived scattering potentials.Comment: 7 pages, 4 figure
Coexistence of the antiferromagnetic and superconducting order and its effect on spin dynamics in electron-doped high- cuprates
In the framework of the slave-boson approach to the model, it is
found that for electron-doped high- cuprates, the staggered
antiferromagnetic (AF) order coexists with superconducting (SC) order in a wide
doping level ranged from underdoped to nearly optimal doping at the mean-field
level. In the coexisting phase, it is revealed that the spin response is
commensurate in a substantial frequency range below a crossover frequency
for all dopings considered, and it switches to the incommensurate
structure when the frequency is higher than . This result is in
agreement with the experimental measurements. Comparison of the spin response
between the coexisting phase and the pure SC phase with a
-wave pairing plus a higher harmonics term (DP+HH) suggests
that the inclusion of the two-band effect is important to consistently account
for both the dispersion of the spin response and the non-monotonic gap behavior
in the electron-doped cuprates.Comment: 6 pages, 5 figure
