As the polarization state of laser can reflect more information, various types of laser remote sensing techniques have been developed. In order to accurately interpret the detection information, the optical components with polarization insensitivity has become an important topic. In this paper, a polarization insensitive splitter with three all-dielectric materials is designed and fabricated, which combines the symmetric structure with the matching layers. Statistical results show that this design has excellent performance of low polarization deviation at short wave region 420-580 nm with high reflectance and long wave region 620-880 nm with high transmittance.

To surmount the shortcomings of powder-based catalysts and small electrode sizes, the development of meter-scale integrated electrode materials is essential for practical electrocatalytic applications, which requires fine control over the effective surface grafting of catalytic active sites on large-size electrodes as well as addressing the challenge of balancing cost-effective and large-scale manufacturing with highly active and stable operation. Herein, we report a low-cost, facile, and scalable method for directly constructing meter-scale single-molecule-integrated catalytic electrodes using commercially available, flexible, and size-tailored conductive carbon textiles (e.g.

Management of African wild dogs (Lycaon pictus) in zoos involves several challenges, including the difficulty of providing appropriate stimulation and enrichment for naturally wide-ranging, energetic, cursorial hunters. Perhaps consequently, zoo packs can exhibit bouts of extreme intra-pack aggression rarely seen in the wild. As with other species, considerable efforts are required to balance the retention and exhibition of wild-type behaviors, against ensuring that the nutritional and welfare needs of individual group-living animals are met.

Purpose: To assess relative glaucoma severity between Haitians and non-Haitians upon presentation to a tertiary referral practice using a retrospective case-control design.
Patients And Methods: All Haitian descent patients were age- and zip code-matched with non-Haitian Hispanic American controls from a tertiary glaucoma service in a 1:1 ratio. Clinical and social vulnerability characteristics were analyzed for differences in functional and structural glaucoma deficits.
Design and validation of A 30 ghz 8 × 8 slot antenna array with ridge waveguide pins/holes layers.

This paper presents an 8 × 8-element slot antenna array optimized for 30 GHz band applications, achieving high gain, wide impedance bandwidth, and high efficiency. The array employs a pin/hole-based design, which enables a compact structure and reduces fabrication complexity and cost, as it eliminates the need for electrical contact between its three primary layers: the metal radiating slot plate, a sub-array cavity layer, and a ridge waveguide feed network layer. The corporate feed network is realized through an array of pins and guiding ridges integrated into a metal plate, effectively distributing power to the radiating elements.
