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.

[Aggregation, deformation and morphology of erythrocytes in patients with ischemic heart disease after injection of ioversol, iodixanol and gadobutrol].

In patients with ischemic heart disease, the administration of contrast agents iodixanol, ioversol and gadobutrol improves (due to the effect of dilution) the aggregation of erythrocytes in vivo, but does not change their deformation ability and the percentage of different morphological forms of erythrocytes (discocytes and ehinocytes) in the blood. The effect of gadobutrol on the aggregation of erythrocytes is characterized by more expressed antiaggregant effect due special molecular properties of this drug.

[Deformation properties of human erythrocytes in the presence of x-ray contrast agents].

It is established that the x-ray contrast agents urografin (76 %), omnipaque-300, optiray-350, ultravist-300, and visipaque-270 produce a dose-dependent decrease in the deformation properties of human erythrocytes in vitro. The degree of manifestation of this negative influence increases with the osmotic activity of agents in the following order: visipaque = ultravist < or = omnipaque < or = optiray < urografin. The effect of these x-ray contrast agents on the deformation of erythrocytes is reversible.

[Possible causes of temperature-dependent disorders of regional circulation in cryoglobulinemia].

We studied effects of changed blood theology in cryoglobulinemia on temperature-dependent disorders of peripheral circulation. The rheological status was assessed by aggregation characteristics of blood at temperature 37 degrees C and 4 degrees C at nephelometry of reverse light diffusion. Blood cryoglobulins concentration was determined spectrophotometrically.

Erythrocytes aggregation in healthy donors at native and standard hematocrit: the influence of sex, age, immunoglobulins and fibrinogen concentrations. Standardization of parameters.

Characteristic parameters of erythrocyte aggregation/disaggregation kinetics in blood samples of 200 healthy donors at native and standard hematocrit were studied. Average aggregation parameters for men and women at native hematocrit significantly differed, but these differences disappeared after hematocrit standardization, only maximal amplitude of aggregation (I(0)) at standard hematocrit in women was still less than in men (p<0.001).
