Data transfer of non-matching meshes in a common dimensionality reduction space for turbine blade

A data transfer method in dimensionality reduction space is proposed for the fluil-structure-interaction problems, which commonly have non-matching meshes at interface. The method provided in the article can reduce the dimensionality of the data transfer by means of projecting interface surface meshes into a dimensionality reduction space. The dimensionality reduction projection can be realized by defining local coordinates system for interface surface. Furthermore, the size of interface surface meshes has little influence on the data transfer. At last, the method is validated using a temperature transfer problem of turbine blade

Distributivity between extended nullnorms and uninorms on fuzzy truth values

This paper mainly investigates the distributive laws between extended nullnorms and uninorms on fuzzy truth values under the condition that the nullnorm is conditionally distributive over the uninorm. It presents the distributive laws between the extended nullnorm and t-conorm, and the left and right distributive laws between the extended generalization nullnorm and uninorm, where a generalization nullnorm is an operator from the class of aggregation operators with absorbing element that generalizes a nullnorm.Comment: 2

Effect of low intensity white light irradiation on the retinas of mice

AIM: To investigate the effect of low intensity white light irradiation on the retinas of mice.<p>METHODS: Thirty C57BL/6J mice were randomly divided into two groups. The number of the mice in each group was 15. The mice in experimental group received dark adaptation from 5:00p.m. to 6:00p.m.,and then exposed to LED white light from 6:00p.m. to 7:00p.m. everyday for a month. At 1, 3, 7, 14 and 30d after the beginning, we examed the histology of mice retinas, calculated the thickness of outer nuclear layer(ONL),inner nuclear layer(INL)and analyzed electrophysiology of mice.<p>RESULTS:One month after experiment, compared to the control group, the latency of Rod-R a wave of the mice in experimental group significantly prolonged, the amplitude of Cone-R b wave of the mice in experimental group significantly decreased and the latency of b wave of the mice in experimental group significantly prolonged(<i>P</i><0.05).There are no significant difference in the histology of retina, ONL and INL thicknesses.<p>CONCLUSION: 100lux low intensity white light could give rise to the impairment of the retinal functions in dark-adapted mice

Tetra­imidazolium piperazinediium bis­(benzene-1,3,5-tricarboxyl­ate) dihydrate

During the crystallization of the title compound, 4C3H5N2 +·C4H12N2 +·2C9H3O6 3−·2H2O, the acidic protons were transferred to the imidazole and piperazine N atoms, forming the final 4:1:2:2 hydrated mixed salt. The mean planes of the three carboxyl­ate groups in the anion are twisted with respect to the the central benzene ring, making dihedral angles of 13.5 (1), 14.5 (1) and 16.9 (1)°. In the crystal, the component ions are linked into a three-dimensional network by a combination of inter­molecular N—H⋯O, O—H⋯O and weak C—H⋯O hydrogen bonds. Further stabilization is provided by π-π stacking inter­actions with centroid–centroid distances of 3.393 (2) Å and weak C=O⋯π inter­actions [O–centroid = 3.363 (2) Å]
