HyperKAN: Kolmogorov-Arnold Networks Make Hyperspectral Image Classifiers Smarter.

In traditional neural network designs, a multilayer perceptron (MLP) is typically employed as a classification block following the feature extraction stage. However, the Kolmogorov-Arnold Network (KAN) presents a promising alternative to MLP, offering the potential to enhance prediction accuracy. In this paper, we studied KAN-based networks for pixel-wise classification of hyperspectral images.

The effective use of adaptogens of various origins on the cattle productivity.

Background: In conditions of industrial animal husbandry, it is necessary to pay attention to the immune system, which regulates metabolic processes in the body of animals. To do this, additives with adaptive properties attract attention.

Aim: The aim is to define a way to increase productivity using adaptogens of plant and animal origin in feeding cattle.

[Mycosis of the maxillary sinus].

In the structure of morbidity and mortality has significantly increased the role of mycoses. The increase in their spread is due not only to the improvement of the quality of diagnosis, but also the emergence of new strains resistant to previously used antifungal drugs, a significant change in the immune status of the population. In addition to environmental factors, it is important to introduce modern methods of treatment that increase survival in the whole spectrum of diseases.

Enhanced THz radiation through a thick plasmonic electrode grating photoconductive antenna with tight photocarrier confinement.

We propose the design of a photoconductive antenna (PCA) emitter with a plasmonic grating featuring a very high plasmonic Au electrode with a thickness of 170 nm. As we show numerically, the increase in h significantly changes the electric field distribution, owing to the excitation of higher-order plasmon guided modes in the Au slit waveguides, leading to an additional increase in the emitted THz power. We develop the plasmonic grating geometry with respect to maximal transmission of the incident optical light, so as to expect the excitation of higher-order plasmon guided Au modes.

Thin active region HgCdTe-based quantum cascade laser with quasi-relativistic dispersion law.

HgCdTe is promising as a material to solve a problem of the development of semiconductor sources with an operational frequency range of 6-10 THz due to the small optical phonon energies and electron effective mass. In this study, we calculate the dependence of the metal-metal waveguide characteristics on the number of cascades for the 3-well design HgCdTe-based quantum cascade laser at 8.3 THz.
