    • An access optimization method for a main memory database based on page-coloring is described. An access sequence of all data pages of a weak locality dataset is ordered by page-color, and all the data pages are grouped by page-color, and then all the data pages of the weak locality dataset are scanned in a sequence of page-color grouping. Further, a number of memory pages having the same page-color are preset as a page-color queue, in which the page-color queue serves as a memory cache before a memory page is loaded into a CPU cache; the data page of the weak locality dataset first enters the page-color queue in an asynchronous mode, and is then loaded into the CPU cache to complete data processing. Accordingly, cache conflicts between datasets with different data locality strengths can be effectively reduced.
    • 描述了基于页面着色的主存储数据库的访问优化方法。 弱位置数据集的所有数据页的访问序列按页面颜色排序,所有数据页按页面颜色分组,然后按照页面颜色顺序扫描弱位置数据集的所有数据页面, 颜色分组。 此外,将具有相同页面颜色的多个存储器页面预设为页面颜色队列,其中在将存储器页面加载到CPU高速缓存之前,页面颜色队列用作存储器高速缓存; 弱位置数据集的数据页首先以异步模式进入页面颜色队列,然后加载到CPU缓存中以完成数据处理。 因此,可以有效地减少具有不同数据局部性强度的数据集之间的缓存冲突。

    • The present invention relates to a method for the preparation of (3S,4S)-3-hexyl-4-((R)-2-hydroxytridecyl)-oxetan-2-one and a product of the method. The method includes the following steps: a) reducing a substance represented by formula (II) to obtain a substance represented by formula (III), and then oxidizing the substance represented by formula (III) to form a substance represented by formula (IV); b) acylating n-octanoic acid to obtain n-octanoyl chloride using thionyl dichloride, then condensing the obtained n-octanoyl chloride with 2-mercapto-pyridine under basic condition to form a substance represented by formula (V), and then converting the substance represented by formula (V) to a substance represented by formula (VI); c) reacting the substance obtained in the step a) with the substance obtained in the step b) under catalytic condition of Lewis acid to generate a substance represented by formula (VII), and then reacting with a Lewis acid. The meanings of the signs in these formulas are the same as those in the description.

    • A wireless device includes a base counter configured to generate counter signals synchronized with timing of a base station. A generation module is configured to generate a timing control signal in response to the counter signals. A transceiver is configured to, based on the timing control signal, (i) transmit data on a time division multiple access channel, and (ii) transmit the data in a first time slot without transmitting data in a second time slot. The first time slot is allocated by the base station for the wireless device. The second time slot is allocated by the base station for a second station. The wireless device is separate from the second station. The second time slot is subsequent to and abuts the first time slot.
