    Synthesis Based on Linearization of Vector Speed Control of an Induction Motor without a Speed Sensor by O. F. Opeiko

    Published 2022-04-01
    “…The simulation of the system was carried out using a simulation model that takes into account the digital software-algorithmic method for generating a microcontroller control signal, as well as electromagnetic processes under conditions of pulse-width modulation in an electric energy converter and an electric motor, the use of the values of the rotor flow coupling vector estimated by the model in coordinate transformations of the system, the formation of a spatial vector of the converter voltage. …”

    Looking though the Past, Present and Future of TMS-EEG by S. N. Martins, C. Romano, B. Ribeiro

    Published 2023-03-01
    “…Results Transcranial magnetic stimulation (TMS) is a safe and reliable method of non-invasive brain stimulation that allows for the local activation of cortical areas through electromagnetic induction. When combining this method with electroencephalography (EEG), it enables the underlying mechanisms of brain diseases. …”

    Study on Two-Dimensional Exit Pupil Expansion for Diffractive Waveguide Based on Holographic Volume Grating by Mianhui Weng, Yizhao Wang, Xuechang Ren, Qinghong Lu

    Published 2023-10-01
    “…Finally, in order to obtain the diffraction efficiency preoptimized by the above DLL for the uniformity of the exit pupil brightness and light energy utilization, we inverse design with the preparation process parameters as the optimization variables and develop the adaptable electromagnetic calculation program Holo-RCWA. Using Holo-RCWA with nondominated sorting genetic algorithm II (NSGA-II), we inverse design to obtain the process parameters satisfying the diffraction efficiency distribution, and the optimization time of the whole system is reduced from 2–3 days to 10 h. …”

    Scapular Resting Posture and Scapulohumeral Rhythm Adaptations in Volleyball Players: Implications for Clinical Shoulder Assessment in Athletes by Augusto Gil Pascoal, Andrea Ribeiro, Jorge Infante

    Published 2023-06-01
    “…It is essential to differentiate between these sports-related adaptations and pathological patterns in clinical assessments, particularly on scapular resting posture and scapulohumeral rhythm. Using an electromagnetic tracking system, the 3D shoulder kinematics of 30 male elite asymptomatic volleyball players and a matching control group were recorded at rest and in eight humeral elevation positions, in 15-degree increments from 15 to 120 degrees. …”

    Nuclear DNA damages generated by reactive oxygen molecules (ROS) under oxidative stress and their relevance to human cancers, including ionizing radiation-induced neoplasia part II... by Robert Nilsson, Ning-Ang Liu

    Published 2020-12-01
    “…The scientific support for a causal link between exposure to non-ionizing electromagnetic radiation and human cancer is judged to be insufficient.As exemplified by diabetes, a common shortcoming when assessing the role of OS in disease is the failure to distinguish between cause and effect - i.e. could the indicators of harmful oxidative stress be the result of the pathological condition in question, rather than its cause.…”
