A method to measure the resonance transitions between the gravitationally bound quantum states of neutrons in the GRANIT spectrometer

We present a method to measure the resonance transitions between the gravitationally bound quantum states of neutrons in the GRANIT spectrometer. The purpose of GRANIT is to improve the accuracy of measurement of the quantum states parameters by several orders of magnitude, taking advantage of long storage of Ultracold neutrons at specula trajectories. The transitions could be excited using a periodic spatial variation of a magnetic field gradient. If the frequency of such a perturbation (in the frame of a moving neutron) coincides with a resonance frequency defined by the energy difference of two quantum states, the transition probability will sharply increase. The GRANIT experiment is motivated by searches for short-range interactions (in particular spin-dependent interactions), by studying the interaction of a quantum system with a gravitational field, by searches for extensions of the Standard model, by the unique possibility to check the equivalence principle for an object in a quantum state and by studying various quantum optics phenomena

Model for Assessing the Asymmetry of a Pigmented Neoplasm

Abstract The paper presents the results of the development of a method for recognizing skin neoplasms based on a model for assessing the asymmetry of the shape of the pigment area of the pathological growth of the epidermis and (or) dermis. Images of pigmented skin neoplasms obtained using a dermatoscope were considered as initial data. To analyze the images, a model was used to calculate the shape asymmetry coefficients obtained relative to the main axes of inertia of the neoplasm, which makes it possible to obtain values independent of the angle of rotation of the images

Image Segmentation of Skin Neoplasms Using the Active Contour Method

Abstract Computer vision technologies are being actively introduced into modern life, including medical practice. The development of such technologies has led to the emergence of computer systems that allow the detection and classification of skin diseases with a quality comparable to and in some cases exceeding human capabilities. The article reveals the method of automatic segmentation on the basis of dermatoscopic images provided by doctors obtained using a digital optical device—a dermatoscope. The main goal of the model being developed is to identify the neoplasm zone and areas of hyperpigmentation on images of skin neoplasms for further integration into medical decision support systems for diagnosing of melanoma. As a result of the work carried out, a software package was created that allows segmentation of the neoplasm. As a demonstration of the method, experimental studies of the detection of melanoma boundaries and zones of areas of signs on images of skin neoplasms are presented. The developed system can be used for diagnostic research and educational purposes
