    Generating new classes of orthogonal polynomials by Amílcar Branquinho, Francisco Marcellán

    Published 1996-01-01
    “…Given a sequence of monic orthogonal polynomials (MOPS), {Pn}, with respect to a quasi-definite linear functional u, we find necessary and sufficient conditions on the parameters an and bn for the sequence Pn(x)+anPn−1(x)+bnPn−2(x),   n≥1P0(x)=1,P−1(x)=0 to be orthogonal. …”

    Effects of Previous Nitrogen Fertilizer Application on Yield and Nitrogen Use Efficiency of Wheat / Maize in the Next Season by Peng ZHOU, Jie WANG, Xinping ZHANG, Yu GONG, Chuangyun WANG, Fei GAO

    Published 2025-02-01
    “…At summer maize tasseling stage (VT) and milky stage (R3), T2 showed 3% and 6% lower leaf area index (LAI) than T3, respectively, with corresponding 6% and 5% lower SPAD values in functional leaves. Notably, compared with T2, T3 displayed significantly higher net photosynthetic rate (Pn) and stomatal conductance (Gs) at big flare stage (V12), but this difference narrowed to 4.4% by R3. …”
