Probabilistic double hierarchy linguistic alternative queuing method for real economy development evaluation under the perspective of economic financialization
With the development of science and technology, the new road
of scientific economic and financial development has played a
decisive role in supporting the financial undertaking. To accelerate the economic development, it is very important to increase
the guiding role of financial undertaking in the real economy.
Therefore, it is necessary to promote the development of the real
economy under the perspective of economic financialization
based on some actions. To judge the implementation effect of
these actions, this paper develops a multiple criteria decisionmaking (MCDM) method to evaluate them. First, the decisionmaking matrices are established with the probabilistic double
hierarchy linguistic term set in which the probabilities are added
to all double hierarchy linguistic terms. Additionally, a weightdetermining method is developed to obtain the weight vector of
criteria, and we develop a MCDM method named the probabilistic
double hierarchy linguistic alternative queuing method (PDHLAQM), where the decision-making result is intuitive by a directed
graph or a 0–1 precedence relationship matrix. Furthermore, we
apply the PDHL-AQM to solve a practical MCDM problem involving the real economy development evaluation under the perspective of economic financialization. Finally, some comparative
analyses are made to show the advantages and reasonableness of
the PDHL-AQM
4-Chlorophenyl 2-oxo-2H-chromene-3-carboxylate
In title compound, C16H9ClO4, the coumarin ring system is approximately planar [maximum deviation = 0.056 (1) Å] and is oriented with respect to the benzene ring at an angle of 22.60 (7)°. Intermolecular C—H⋯O hydrogen bonding is present in the crystal
Oosporein from Tremella fuciformis
The title compound [systematic name: 3,3′,6,6′-tetrahydroxy-4,4′-dimethyl-1,1′-bi(cyclohexa-3,6-diene)-2,2′,5,5′-tetraone], C14H10O8, was isolated from Tremella fuciformis. The molecule has 2 symmetry, with the mid-point of the C—C bond linking the cyclohexadienedione rings located on a twofold rotation axis. In the molecule, the ring is approximately planar, with an r.m.s. deviation of 0.0093 Å, and the two rings make a dihedral angle of 67.89 (5)°. Intermolecular O—H⋯O hydrogen bonding occurs in the crystal structure
Release Profile of Nitrogen during Thermal Treatment of Waste Wooden Packaging Materials
In this paper, the fast pyrolysis experiment of particle board was carried out on a fixed bed reactor and a Py-GC/MS equipment. The effects of temperature and gas phase residence time on the product yields and its components distribution were investigated. The effect of components of particle board on product yields and its components distribution was also investigated. The results showed that the temperature has a great influence on the yields of fast pyrolysis products, and the yield of pyrolysis oil reached the highest at 550°C. The urea-formaldehyde resin would prevent the pyrolysis of particle board. Compared with the bio-oil from fast pyrolysis of wood, the major components of the bio-oil from fast pyrolysis of particle board did not change much
Influence of variable domain glycosylation on anti-neutrophil cytoplasmic autoantibodies and anti-glomerular basement membrane autoantibodies
<p>Abstract</p> <p>Background</p> <p>The pathophysiological significance of variable region glycosylation of autoantibodies is still unclear. In the current study, the influence of the variable region N-linked oligosaccharides on the reactivity of three autoantibody specificities was investigated with Sambucus nigra agglutinin (SNA), which mainly binds to oligosaccharides with terminal α2, 6-linked sialic acid on the variable region of IgG.</p> <p>Methods</p> <p>Twenty-seven patients with serum positive anti-neutrophil cytoplasmic autoantibodies (ANCA) against myeploperoxidase (MPO) or proteinase 3 (PR3), or autoantibodies against glomerular basement membrane (GBM) were included. Total IgG was isolated and separated into non-SNA-binding and SNA-binding fractions with SNA affinity chromatography. Antigen-specific IgG was purified by immunoaffinity chromatography.</p> <p>Results</p> <p>At the same concentration of IgG, the antigen binding level of non-SNA-binding IgG was significantly lower than that of SNA-binding IgG for MPO-ANCA (absorbance value at 405 nm, 0.572 ± 0.590 <it>vs</it>. 0.962 ± 0.670, P < 0.001) and for PR3-ANCA (0.362 ± 0.530 <it>vs</it>. 0.560 ± 0.531, P = 0.003). The antigen binding level of non-SNA-binding IgG was significantly higher than that of SNA-binding IgG for anti-GBM antibodies (1.301 ± 0.594 <it>vs</it>. 1.172 ± 0.583, P = 0.044). The level of variable region glycosylation of total IgG was significantly lower than that of affinity-purified MPO-ANCA (1.021 ± 0.201 <it>vs</it>. 1.434 ± 0.134, P = 0.004). The level of variable region glycosylation of total IgG was significantly higher than that of affinity-purified anti-GBM antibodies (1.034 ± 0.340 <it>vs</it>. 0.734 ± 0.333, P = 0.007). The SNA-binding fraction of MPO-ANCA-containing IgG and PR3-ANCA-containing IgG induced higher levels of neutrophil oxygen radical production than the corresponding non-SNA-binding fractions (P < 0.001 and P = 0.043, respectively). The level of variable region glycosylation of affinity-purified MPO-ANCA was higher in active AAV than the same patients in remission (P = 0.001).</p> <p>Conclusion</p> <p>Characteristics of variable region glycosylation of ANCA and anti-GBM antibodies were different from that of total IgG, which might influence the antigen-binding ability of these antibodies. Variable region glycosylation of ANCA might influence the effect of ANCA-induced neutrophils respiratory burst.</p
Periodic driving induced helical Floquet channels with ultracold atoms in momentum space
Employing the external degrees of freedom of atoms as synthetic dimensions
renders easy and new accesses to quantum engineering and quantum simulation. As
a recent development, ultracold atoms suffering from two-photon Bragg
transitions can be diffracted into a series of discrete momentum states to form
a momentum lattice. Here we provide a detailed analysis on such a system, and,
as a concrete example, report the observation of robust helical Floquet
channels, by introducing periodic driving sequences. The robustness of these
channels against perturbations is confirmed, as a test for their topological
origin captured by Floquet winding numbers. The periodic switching demonstrated
here serves as a testbed for more complicated Floquet engieering schemes, and
offers exciting opportunities to study novel topological physics in a many-body
setting with tunable interactions.Comment: partial overlap with the last section of arxiv:1906.12016V1, which
