该gc模块公开了一种运行探测器(collect()功能)的方法,以及配置接口和在运行时禁用探测器的功能。循环检测器被视为可选组件,虽然它是默认包含的,但它可以在构建时使用Unix平台(包括Mac OS X)上--without-cycle-gc的configure脚本选项来禁用,如果循环检测器以这种方式被禁用,gc模块将不可用。 Python中的引用计数 宏...
NSString, NSDictionary, NSArray, 和 NSNumber 字面值应该用在任何创建不可变的实例对象。特别小心不要把 nil 放进 NSArray 和 NSDictionary 里,这会导致崩溃 例子: 复制 NSArray *names = @[@"Brian", @"Matt", @"Chris", @"Alex", @"Steve", @"Paul"];NSDictionary *productManagers = @{@"iPh...
DiI即DiIC18(3),全称为1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate,是最常用的细胞膜荧光探针之一,呈现橙红色荧光。DiI是一种亲脂性膜染料,进入细胞膜后可以侧向扩散逐渐使整个细胞的细胞膜被染色。

2.4 Controlling the Compiler Through Environment Variables An environment variable is a system symbol that you define and assign a string to. Setting environment variables is useful when you want to run the compiler repeatedly without re-entering options, input filenames, or pathnames. NOTE C_...

The thyroid parafollicular cell, or commonly named “C-cell,” functions in serum calcium homeostasis. Elevations in serum calcium trigger release of calcitonin from the C-cell, which in turn functions to inhibit absorption of calcium by the intestine,..
14. c-Myc exerts neoplastic effects by integrating various signals to affect a diverse array of cellular processes, including DNA replication, cell growth, metabolism, cell cycle progression, and so on15,16,17. Since c-Myc dysregulation is a unique feature in the genetic landscape of MM, it ...
The data platform reported through this interface will be parsed, and the data in the structure must be consistent with the attributes defined in the profile. ST_IOTA_DEVICE_DATA_INFO is a structure array, which can report multiple sub-device data at the same time. Each sub-device can repor...
