Visualization of Higher-Order Topological Insulating Phases in Two-Dimensional Dielectric Photonic Crystals.

The studies of topological phases of matter have been developed from condensed matter physics to photonic systems, resulting in fascinating designs of robust photonic devices. Recently, higher-order topological insulators have been investigated as a novel topological phase of matter beyond the conventional bulk-boundary correspondence. Previous studies of higher-order topological insulators have been mainly focused on the topological multipole systems with negative coupling between lattice sites.

Theoretical study of the spectroscopic and nonlinear optical properties of trans- and cis-4-hydroxyazobenzene.

We investigate the molecular structure, vibrational and electronic absorption spectra, and electronic hyperpolarizabilities of trans and cis isomers of 4-hydroxyazobenzene (HOAB) via density functional theory. Results show that the azo dye exhibits a high third-order nonlinear optical response and good optical transparency. Both the basis set and the functional are important influences on the results obtained when calculating the absorption spectrum and NLO response.

Solvent effects on polarizability and hyperpolarizability of spirobifluorene derivative.

We studied the solvent effect on the geometric structure and (hyper)polarizability of spirobifluorene derivative by using quantum chemistry calculations. We found that the geometric structure is slightly affected by the solvent polarity. However, solvent polarity significantly influences first hyperpolarizability and second hyperpolarizability respectively.

TE-mode coplanar imaging using weakly anisotropic metasurface.

We analyze and experimentally realize coplanar imaging of transverse-electric (TE) modes surface waves using weakly anisotropic metasurface consisting of non-periodic subwavelength U-shaped metallic structures. Such metallic structures with the exciting coplanar dipole are integrated on the top surface of a thin dielectric board. A circuit model is utilized to analyze the characteristics of the surface waves supported by the metasurface.

[Influence of enteral administration of hypertonic electrolyte glucose solution on the intestinal barrier and organ functions in dogs with severe burn].

Objective: To study the change in intestinal barrier and organ functions of burned dog after enteral administration of hypertonic electrolyte glucose solution (HEGS) in shock stage.

Methods: Twenty-four Beagle dogs inflicted with 35% TBSA full-thickness burn were divided into no-fluid group (NF), intravenous infusion with isotonic electrolyte glucose solution (IEGS) group (II group), enteral infusion with IEGS group (EI), and enteral infusion with HEGS group (EH) according to the random number table, with 6 dogs in each group. Saline, containing 50 g/L glucose, was intravenously or enterally infused into dogs in II group and EI group respectively 0.

[The curative effect of 1.8% hypertonic electrolyte glucose solution in enteral resuscitation of burn shock].

Objective: To study the resuscitative effect of hypertonic electrolyte glucose solution (HEGS) in enteral resuscitation of burn shock.

Methods: Eighteen Beagle dogs with 35% TBSA full-thickness flame injury were used in this study. They were randomized to a control group (no-fluid resuscitation, N group), a HEGS resuscitation group (H group) or an isotonic electrolyte glucose solution (IEGS) resuscitation group (I group).
