Memnglomas are the second most common intracranial benign rumors and represent about15%-24% of primary brain tumors.1 Most meningiomas grow slowly at a rate of only 2.4 mm annually.2 Due to their slow growth, few clinical symptoms occur until the tumor reaches a large size. If the meningioma grows at the front or rear of the cranial cavity, it can grow to be very large before that area＇s vital functions are affected. Therefore, giant meningiomas are not infrequent, and actually account for 11.9% of meningiomas in our hospital. Because the volume of the giant meningioma is large,

为了改善涡轮排气蜗壳的气动性能,通过搭建NUCEMCA和Isight的集成优化平台,探索了一种多变量的优化方法,即对蜗壳参数化后,用优化的拉丁方试验设计获得空间均匀分布的试验样本,通过数值模拟求出各样本点性能参数,建立径向基神经网络代理模型(RBF),再运用自适应模拟退火算法(ASA)和直接搜索法(Hooke-Jeeves)得到最终的优化设计参数组合。结果表明,在不提高涡轮出口静压的前提下,在设计工况,优化后的蜗壳总压损失系数在原始蜗壳的基础上降低了9.82%,静压恢复系数最高提高了12.2%,出口速度分布也更加均匀,表明了优化系统的有效性。

The electroreduction of carbon dioxide to generate multicarbon products is significant for achieving a carbon-neutral economy. However, the selectivity for multi-carbon products faces several challenges, such as the intricate nature of the multistep hydrogenation processes, slow reaction kinetics and the bicarbonate precipitate issue caused by alkaline conditions. These factors hinder the extensive utilization of this reaction. Herein, we successfully developed and implemented a tandem electrolyzer cascade to separate and optimize the complex elementary reactions involved in the process of multi-carbon production. This approach enables us to enhance the Faradaic efficiency (FE) of each step, consequently improving the overall performance of the system. An ethanol-assisted ionic-exchange method was utilized to synthesize a Ni
