The possibility of noninvasive detection of magnetic particles in biological objects has been investigated. It has been found that magnetic particles, including magnetite, hematite, and catalytic iron particles in carbon nanotubes, can be detected by ultrasensitive magnetic field sensors with resolutions of 10−8-10−14 T. This research direction is shown to be promising for noninvasive monitoring of organs, implants, prosthesis, and other elements of biological systems.

In the article the development, operation principles and interface of the cross-platform mobile application for the neuro-electrostimulator ‘SYMPATHOCOR-01’ were described. The developed application makes possible to remotely control the device using Bluetooth Low Energy technology. The advantages of the application were compared with the native application based on Android. It was shown that memory footprint has decreased 3-fold, source lines of program code has decreased by 2.5 times, the number of potential user has increased by 1.5 times, minimal RAM usage increased 4-fold, the maximal usage of RAM increased by 20 MB, minimal CPU usage increased 5-fold, maximal CPU usage increased by 14%. The application interface copies the interface of the ‘SYMPATHOCOR-01’ device from 1997, which ensures legacy of the mobile application interface.

In wireless sensor networks, an aggregation of information to the one recipient node is the common technic. Modern hardware platforms for sensor nodes have transmitters with a two-level transmission power (normal and burst). In this article, we consider route structure construction in such platforms for maximization network lifetime. At recent time several algorithms for optimal route structure construction have been developed. We adopt one of such routing algorithms for two-level transmitters and formulate the analytical criterion of efficiency for this type of sensor nodes. Proposed solution consist of replacing each burst edge in network graph by two normal edges with equivalent energetical parameters, after that optimal route tree has been constructed in this modified graph. Simulation of this approach shows that it gives an advantage in maximum network lifetime for selected network configuration.

A method and algorithm for remote monitoring of patients in asthma is discussed. The method includes a comprehensive evaluation of the results of standardized questionnaire about disease symptoms, changes in the bronchodilator intake regimen and data of functional test of respiratory systems state. The proposed functional test is based on the assessment of the duration of tracheal sounds in the frequency band of 200–2000 Hz registered during forced expiratory maneuver. To record tracheal sounds a lapel microphone placed at the mouth outside the exhaled airflow is used. The algorithm of processing and analysis of diagnostic data is described. The developed diagnostic algorithm proved its effectiveness in the long-term monitoring of a group of healthy individuals and patients in asthma.

Complex postural loads have a significant effect on all systems of the human body. Such movements in space create unique conditions for the correction of his hemodynamics. Special technical means are required to ensure reliable registration of physiological parameters. The aim of the work was the development of such a multi-channel device with high accuracy of analog to digital signal conversion and wireless data transmission. To develop the device, methods of automatic control and digital signal processing were used. Schemes of adaptive amplification of signals with automatic choice of a working point have been developed. The device is implemented on the basis of a modern electronic base using fast ADCs (1000 kbps), microcontrollers (32 bits) and Bluetooth modules (4th generation). The tests that confirmed the declared characteristics were carried out. Also, the developed device was used in a complex study of the neuro-systemic reactions of the human body to complex postural loads.

HER2/neu status of breast cancer is important for treatment strategy choice, but nowadays it is evaluated manually by pathologist. The automation of this procedure is an urgent task, because it will allow to free a pathologist from routine work. But the problem of cells segmentation is difficult for classical methods of computer vision due to the frequent presence of erythrocytic background and non-cellular elements at specimen' image. In this work we propose segmentation algorithm, based on deep convolutional neural networks. Is it has been shown that using this approach, it's possible to get better results, than using classical computer vision algorithms.
