title: HERPETIC STOMATITIS: BIOLOGY, CLINICAL MANIFESTATIONS AND PROPHYLAXIS

description: Herpetic stomatitis is a common oral infection caused by the herpes simplex virus type 1 (HSV-1), affecting a large portion of the global population, particularly children and young adults. During primary infection in children, the disease can manifest as severe gingivostomatitis, accompanied by high fever and painful oral ulcers. For immunocompromised patients, the infection carries a risk of serious complications, including dissemination to internal organs and the central nervous system. The disease leads to severe consequences not only for health but also socio-economically. It increases medical costs, causes absenteeism from work and school, and leads to nutritional and developmental problems in children. Current treatment is aimed only at suppressing the virus and cannot completely eliminate it from the body. Furthermore, antibiotic resistance, the lack of prophylactic vaccines, and the incomplete understanding of its pathogenesis necessitate new research. This article is dedicated to analyzing the pathogenesis, clinical manifestations, and prevention methods of herpetic stomatitis based on modern scientific data. It discusses the virus's replication mechanisms, immune response, various forms and complications of the disease, as well as individual and public health preventive measures. The article aims to provide useful knowledge and recommendations for clinicians in practice, aiding in early detection, correct diagnosis, and the organization of effective prevention strategies.

title: Matlab and R Codes for trajectory analyses in ichnology

description: These are the MATLAB and R codes for trajectory analysis of a fossil trail. Trajectory.m and Trajectory.R analyze trajectory-related metrics, including turning-angle series, frequency spectra (single-sided representation), autocorrelation functions, the minimal normalized radius of curvature, the smoothness index, and the Shannon index, based on a series of (x, y) coordinates (such as the two series of values x, y in the attached "Coordinates.txt"). Fractal_index.m and Fractal_index.R compute the fractal index from an image in which the trajectory is shown in black against a white background (such as the attached "Forage"). It should be noted that, for smoothness analyses, the minimal value of F is 2 by definition (of smoothness index), which is also the standard choice. Although F can be set slightly higher, the manuscript “Reproducing and understanding a fossil trail in digitized worlds: a protocol to quantitative analyses of movement trajectories” shows that excessively large F values introduce substantial noise.

description: These are the MATLAB and R codes for trajectory analysis of a fossil trail. Trajectory.m and Trajectory.R analyze trajectory-related metrics, including turning-angle series, frequency spectra (single-sided representation), autocorrelation functions, the minimal normalized radius of curvature, the smoothness index, and the Shannon index, based on a series of (x, y) coordinates (such as the two series of values x, y in the attached "Coordinates.txt"). Fractal_index.m and Fractal_index.R compute the fractal index from an image in which the trajectory is shown in black against a white background (such as the attached "Forage"). It should be noted that, for smoothness analyses, the minimal value of F is 2 by definition (of smoothness index), which is also the standard choice. Although F can be set slightly higher, the manuscript “Reproducing and understanding a fossil trail in digitized worlds: a protocol to quantitative analyses of movement trajectories” shows that excessively large F values introduce substantial noise.
