雌蕊群

Multi tool use雌蕊群,或雌花器(英语:Gynoecium),為被子植物花中的心皮的總稱。[1]傳統上把較典型形態的花的花部中,由子房、花柱、柱頭等部位構成者稱為雌蕊(pistil),但在一朵花為多心皮、離生的狀態下,雌蕊一詞的概念便易生混淆,故現在植物系統學上常採用較為精準的雌蕊群。
一朵花中的心皮數目可能單一(單一心皮)、或二個以上合生或離生。
單一心皮的例子如豆科植物,成熟後發育為豆莢(莢果)。
具多數離生心皮的例子如木蘭科(白玉蘭)、八角茴香科(八角)、某些薔薇科(玫瑰)的植物。
具多數合生心皮的種類,其心皮癒合成雌蕊,概分為柱頭、花柱、子房等部。例如瓜類(瓜科),其子房或果實橫剖開可見到其切面由三個部份合生而成。

1 I having trouble getting my ResourceDictionary.MergedDictionaries to load from app.xaml. My WPF app has a static class with a Main defined and startup object set to it. Within Main I created an instance of App and run it. The override OnStartup fires and the mainwindow.cs InitializeComponent gives the error "Message "Cannot find resource named 'MaterialDesignFloatingActionMiniAccentButton'. If I put the resources in the mainwindow.xaml everything is fine, but I wanted them to load at the app level so I they are not in each page. Any help appreciated. public partial class App protected override void OnStartup(StartupEventArgs e) base.OnStartup(e); var app = new MainWindow(); var context = new MainWindowViewModel(); app.DataContext = context; app.Show(); from the Main.. var app = new App(); app.Run(); app.xaml.. <Application x:Class="GS.Server.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:...
up vote 2 down vote favorite There is a clear pattern that show for two separate subsets (set of columns); If one value is missing in a column, values of other columns in the same subset are missing for any row. Here is a visualization of missing data My tries up until now, I used ycimpute library to learn from other values, and applied Iterforest. I noted, score of Logistic regression is so weak (0.6) and thought Iterforest might not learn enough or anyway, except from outer subset which might not be enough? for example the subset with 11 columns might learn from the other columns but not from within it's members, and the same goes for the subset with four columns. This bar plot show better quantity of missings So of course, dealing with missings is better than dropping rows because It would affect my prediction which does contain the same missings quantity relatively. Any better way to deal with these ? [EDIT] The nullity pattern is confirmed: machine-learning cor...
