  2. Fukui function - Wikipedia

    en.wikipedia.org/wiki/Fukui_function

    The Fukui function is named after Kenichi Fukui, who investigated the frontier orbitals described by the function, specifically the HOMO and LUMO. [3] Fukui functions are related in part to the frontier molecular orbital theory (also known as the Fukui theory of reactivity and selection, also developed by Kenichi Fukui) which discusses how nucleophiles attack the HOMO while at the same time ...

  3. Weitao Yang - Wikipedia

    en.wikipedia.org/wiki/Weitao_Yang

    Yang's main contributions to theoretical chemistry range from fundamental theory to applications of density functional theory. He (with Parr) developed the concepts of the Fukui function, [1] hardness, and softness [2] in density functional theory. He also justified the theoretical ground of potential functional (as in Optimized-Effective ...

    en.wikipedia.org/wiki/Kenichi_Fukui

    Kenichi Fukui (福井 謙一, Fukui Ken'ichi, October 4, 1918 – January 9, 1998) was a Japanese chemist. [1] He became the first person of East Asian ancestry to be awarded the Nobel Prize in Chemistry when he won the 1981 prize with Roald Hoffmann , for their independent investigations into the mechanisms of chemical reactions .

  5. Frontier molecular orbital theory - Wikipedia

    en.wikipedia.org/wiki/Frontier_molecular_orbital...

    Fukui's own work looked at the frontier orbitals, and in particular the effects of the highest occupied molecular orbital and the lowest unoccupied molecular orbital on reaction mechanisms, which led to it being called frontier molecular orbital theory (FMO theory).

  6. Activation function - Wikipedia

    en.wikipedia.org/wiki/Activation_function

    The activation function of a node in an artificial neural network is a function that calculates the output of the node based on its individual inputs and their weights. Nontrivial problems can be solved using only a few nodes if the activation function is nonlinear .

    The first family of Minnesota functionals, published in 2005, is composed by: M05: [13] Global hybrid functional with 28% HF exchange. M05-2X [14] Global hybrid functional with 56% HF exchange.

    en.wikipedia.org/wiki/Talk:Fukui_function

    "The f+ function represents the initial stage of a reaction in which the molecule of interest acts as an electrophile. The f- function, on the other hand, represents the initial stage of a reaction in which the molecule of interest acts as nucleophile." 129.82.95.87 16:12, 18 May 2023 (UTC)
