    Design of wideband low-loss reconfigurable reflectarray antenna by Zhang, Xiran

    Published 2024
    “…It proposes an RRA design that integrates a PIN diode with air gap. The switch of the reconfigurable unit is directly mounted on the reflective element, reducing the loss introduced by the switching device. …”

    Dynamic in vivo imaging of small animal brain using pulsed laser diode-based photoacoustic tomography system by Upputuri, Paul Kumar, Pramanik, Manojit

    Published 2017
    “…The system takes advantage of an 803 nm pulsed laser diode having high repetition rate ~7000 Hz combined with a fast-scanning single-element ultrasound transducer leading to a 5 seconds cross-sectional imaging. Cortical vasculature is imaged in scan-time of 5 seconds with high signal-to-noise ratio ~48. …”

    Negative density dependence promotes persistence of a globally rare yet locally abundant plant species Oenothera coloradensis by Stears, AE, Heidel, B, Paniw, M, Salguero-Gómez, R, Laughlin, DC

    Published 2024
    “…We used integral projection models (IPMs) to examine the population dynamics of <em>Oenothera coloradensis</em>, a rare, monocarpic perennial forb, and determine whether any of five proposed demographic mechanisms for rare species persistence contribute to the long-term viability of two populations. …”

    A 1-bit 16×16 reconfigurable intelligent surfaces array for C-band by Zhang, Yucheng

    Published 2025
    “…Their characteristics make them a promising technique which could improve the performance of mobile communication systems especially for 5G and 6G communications. RIS array is achieved by combining a number of basic elements together with PIN diodes which control the on and off state of RIS units. …”
