    Abstract: In emergency situation robot control system stops the manipulator by shutdowning drivers and activating brakes. This mode is used in all cases of equipment failure detection or while alarm bottom is pressed on control panel. Emergency braking is uncontrolled motion. As result manipulator movement deviates from program trajectory as the relations between velocities in joints differ significantly. This creates danger of collisions with objects in robot work space. The paper describes device that can be connected to control system. Connection needs insignificant changing in hardware architecture of robot control system. Device consists of controller and individual electronic schemes that are able to activate brakes of each degree of freedom regardless from other one. This feature allows to design braking trajectory by activating brakes in specific sequence and calculated delays. Mathematical solution for deviation minimization problem of braking trajectory from program one is presented. The solution is reduced to mathematical formulas which depend of the temporary velocities and values of braking decelerations in manipulator joints. The considered way of control differs from similar one described earlier by that in emergency situation drivers turn off immediately. On the first stage manipulator brakes by friction forces in gear boxes. Theoretical evaluations show that in all cases this reduces deviations from program trajectory. Additionally the new way can be used even if fault takes place at least one of drivers.

    Abstract: Numerical simulation is widespread method to investigate machines and robotic mechanisms in different applications. Program complexes such as MATHLAB Simulink and similar ones are based on the assumption that mechanism kinematics can be described by kinematic scheme and it does not change on time interval of simulation. This is used to generate equations of dynamics automatically and then calculate the mechanism motion. Formulated assumption does not take place for numerous applications cause a set of contact points between mechanism parts is not permanent. This circumstance restricts application area of simulation method and accuracy of investigations. "Physical drives" are software systems for motion simulation of interacting bodies in real time. This restricts the complicity of dynamics model that are used in simulation. The paper describes the simulation method in which mechanism is represented as mechanical system of geometrical bodies. Their motion is defined by Lagrange virtual movement principle. Simulation algorithm generates equations automatically when all contact points between mechanism parts and with external environment are found. Simulation program was been used to investigate the motion of cylindrical shaft in assembly operation. It was been became all scenarios of shaft motion relatively hole. Each of them is defined by initial position of shaft and hole and also mechanical features of assembly device units or features of assembly manipulator servo control system. Simulation algorithm calculates assembly force, forces and moments are acted in mechanism and between mating surfaces. Developed simulation program can be used for choosing of constructive parameters and defining acceptable deviation in initial shaft position.

    Abstract: We herein present our initial report from «ROKKOR-recipient», a national multicenter observational study. The prevalence, risk factors, clinical manifestations and outcomes of the novel coronavirus disease 2019 (COVID-19) in solid organ transplant recipients receiving immunosuppressive therapy were investigated. The study enrolled 251 COVID-19 patients (220 kidney recipients, 7 liver recipients, 1 liver-kidney recipient, and 23 heart recipients). The subjects came from 20 regions in Russia. The symptoms, clinical presentation, imaging and lab test results, therapy and outcomes of COVID-19 were described. It was established that solid organ transplant recipients with COVID-19 have a higher risk of developing adverse events. Predictors of adverse events include associated cardiovascular diseases, pulmonary diseases, diabetes, and kidney failure. Symptoms of the disease include dyspnea, rash and catarrhal signs, as well as initial low blood oxygen saturation (SpO 2 〈 92%), leukocytosis (white blood cell count 〉 10 × 10 9 /L), elevated creatinine levels ( 〉 130 μmol/L) and a marked decrease in glomerular filtration rate, requiring hemodialysis. Performing organ transplant surgery in COVID-19 does not increase the risk of adverse events but could save the lives of waitlisted terminally ill patients.

    Abstract: INTRODUCTION: Navigational transcranial magnetic stimulation (NTMs) is used in neurosurgical practice to identify functionally important motor areas of the brain for the purpose of safe resection of a tumor focus. At the same time, when planning radiation therapy (LT) and determining the amount of irradiation, until recently, functionally significant zones of topical representation of skeletal muscles in the cerebral cortex were not taken into account. This study evaluates the use of mapping motor areas of the cerebral cortex using NTMs when planning LT in patients with malignant gliomas affecting the motor cortex. OBJECTIVE: To evaluate the possibilities of navigational transcranial magnetic stimulation in the pre-radiation preparation of patients with brain tumors. MATERIALS AND METHODS: The study included 31 patients with gliomas of a high degree of malignancy who received radiation and/or chemoradiotherapy at the RSCRT from 2020 to 2022. The median follow-up was 12.1 months (3.0–24.5 months), while all patients were followed up to the control, 3-month follow-up period after the end of the course of radiation therapy, 23 patients showed up for control after 6 months (two patients died between 3-month and 6-month control). Statistics: analysis was performed using the Statistica 10.0 software (StatSoft, Inc., USA). RESULTS: Three out of 31 patients had improved motor function, while eight out of 31 patients had decreased motor function. Moreover, when comparing the preoperative condition with the condition during control examinations six months after radiation therapy, motor function improved in three patients, and decreased in eight. Maps of motor zones of NTMs overlapped PTV by 41.2%. The average dose of Dmean maps of NTMs was 42.3 Gy (3.7–61.1 Gy) and 37.0 Gy (3.6–55.8 Gy) with a limit of 45 Gy per motor zone. Thus, the average dose of Dmean according to the maps of the motor zones of NTMs was significantly reduced by 5.3±3.3 Gy (14.3%, p 〈 0.05). The average dose of Dmean on NTMs cards was reduced by 4.6±3.5 Gy (12.8%, p 〈 0.05) to 37.8 Gy. The average volume of NTMs cards receiving a dose equal to or greater than 45 Gy and 55 Gy can be significantly reduced by 11.3% and 8.4%, respectively, with dose restriction (p 〈 0.001). Anatomical ORS (optic nerve chiasm and brain stem) were not affected in relation to the average dose of Dmean or the maximum dose with an increase in the dose to GTV. DISCUSSION: In our study, it was shown that maps of the motor zones of NTMs can be used in the planning of LT patients with gliomas of high malignancy. To date, the primary motor cortex has not been considered as an OR in such patients. The results of the study demonstrated that the dose in relation to the maps of the motor zones of NTMs can be significantly reduced without affecting the therapeutic doses for PTV. CONCLUSION: LT planning using NTMs motor maps can help reduce the radiation dose to the motor cortex in primary LT, although the motor cortex appears morphologically rather insensitive to LT compared to speech zones and areas of high-order cognitive processes, such as the temporal and limbic cortex.
