Abstract Dynamic inversion of the planar-chiral responses a metasurface is experimentally demonstrated in terahertz regime. To realize this inversion, critical transition checkerboard-like metallic structures used. Resonant with planar chirality and their complementary enantiomeric patterns are embedded checkerboard. Using vanadium dioxide as variable resistance, implemented The to circularly p...

An analytical work on intrinsic localized modes in a two-dimensional Heisenberg ferromagnet the checkerboard lattice is presented. Taking advantage of an asymptotic method, governing dynamical equations are reduced to one (2 + 1)-dimensional nonlinear Schrödinger equation. In our work, we obtain two types mode solutions, namely, Brillouin zone center and corner modes. The occurrence conditions ...

The square checkerboard buckling deformation appearing in indium antimonide infrared focal-plane arrays (InSb IRFPAs) subjected to the thermal shock tests, results in the fracturing of the InSb chip, which restricts its final yield. In light of the proposed three-dimensional modeling, we proposed the method of thinning a silicon readout integrated circuit (ROIC) to level the uneven top surface ...

With the rise in multidrug-resistant (MDR) bacterial infections, there has been increasing interest in combinations of ≥2 antimicrobial agents with synergistic effects. We established an MDR bacterial strain library to screen for in vitro antimicrobial synergy by using a broth microdilution checkerboard method and high-throughput luciferase-based bacterial cell viability assay. In total, 39 MDR...

The aim of this study was to use molecular identification methods, such as 16S RNA gene sequence and reverse-capture checkerboard hybridization, for identification of the bacteria associated with dental caries and with dental health in a subset of 204 twins aged 1.5 to 7 years old. A total of 448 plaque samples (118 collected from caries-free subjects and 330 from caries-active subjects) were u...

The combination of light detection and rangings (LiDARs) cameras enables a mobile robot to perceive environments with multimodal data, becoming key factor in achieving robust perception. Traditional frame are sensitive changing illumination conditions, motivating us introduce novel event make LiDAR-camera fusion more complete robust. However, jointly exploit these sensors, the challenging extri...

Background: The development of resistance to antimicrobial agents is a major problem in chemotherapy. Finding agents which potentiate antimicrobial activity could be favorable. There are some reports that methylxanthines changed the inhibitory effect of antibacterial agents. Thus, possible synergistic effect of methylxanthines, aminophylline and caffeine on some antibiotics, carbenicillin, ceft...

Recent scanning tunneling microscopy measurements which indicate the formation of two-dimensional density modulations at some doping levels in cuprates were reviewed. A model of hard-core bosons which represent bound hole pairs in the two-dimensional doped antiferromagnet was discussed in the context of these experimental results. By means of an exact numerical diagonalization it was shown that...

A regular circuit structure called a Checkerboard (CB) is proposed. In some CB configurations, all mask layers except the via layers are pre-designed, which is attractive for high manufacturability and performance predictability and for lowering mask costs. The synthesis algorithms developed for the CB makes use of their structural regularity and flexibility. No technology mapping is needed; pl...

In this paper, we consider the family of rational maps Fλ(z) = z n + λ zd , where n ≥ 2, d ≥ 1, and λ ∈ C. We consider the case where λ lies in the main cardioid of one of the n − 1 principal Mandelbrot sets in these families. We show that the Julia sets of these maps are always homeomorphic. However, two such maps Fλ and Fμ are conjugate on these Julia sets only if the parameters at the center...
