    Decreased Incidence of Type 1 Diabetes in Young Finnish Children by Anna Parviainen (9343391)

    Published 2020
    “…We assessed sex-specific incidence rates (IRs) per 100,000 person years (PY) by 4-year time periods in three age groups (0.50–4.99, 5.00–9.99, and 10.00–14.99 years).…”

    Pulse Ultrasound-Based Response Enhancement of a MOX Gas Sensor by Yumin Yang (5737235)

    Published 2024
    “…Comparing the steady responses of five target gases under the pulse and continuous ultrasound, respectively, it is found that the pulse ultrasound causes a better catalysis effect, and response enhancement (RE) by the pulse ultrasound with an optimal pulse width depends on the ultrasonic strength as well as the species and concentration of the target gas. For 2 ppm methanol, the RE by the pulse ultrasound is 50%, relative to the continuous ultrasound, when the pulse width, duty ratio, and working frequency are 0.4 ms, 50%, and 110.1 kHz, respectively. …”
