A Dominant Resource Fairness （DRF） based scheme for job scheduling in distributed cloud computing systems which was modeled as multi-job scheduling and multi-resource allocation coupling problem is proposed, where the resource pool is constructed from a large number of distributed heterogeneous servers, representing different points in the configuration space of resources such as processing, memory, storage and bandwidth. By introducing dominant resource share of jobs and virtual machines, the multi-job scheduling and multi-resource allocation joint mechanism significantly improves the cloud system＇s resource utilization, yet with a substantial reduction of job completion times. We show through experiments and case studies the superior performance of the algorithms in practice.

Magnetic shape memory alloys(MSMAs), both in condensed matter physics and in material science, are one of the most extensive research subjects. They show prompt response to the external magnetic field and give rise to large strain and have fine reversibility. The well-known example is Heusler-type MSMAs, which possess excellent multifunctional properties and have potential applications in energy transducer, actuator, sensor, microelectromechanical system, and magnetic refrigerator. In this paper, it is shown the recent progress in magnetostructural transformation, magnetic properties, shape deformation, magnetocaloric effect as well as magnetic field-induced shape memory effect in Ni–Mn–Ga, Ni Mn Z(Z = In, Sn, Sb),and Ni Co Mn Z(Z = In, Sn, Sb, Al) Heusler-type *** remaining issues and possible challenges are briefly discussed.

背景:研究表明,脑黑质结构的病变是导致帕金森病的主要原因。从影像学角度来看,结构微小的黑质空间位置信息、体积以及3D结构形态的分析为帕金森病的临床诊断和治疗效果评价提供了十分有力的工具,因此其三维形态的研究工作尤为重要。由于恒河猴与人类的生理十分相似,这使它成为许多科学研究中比较理想的实验对象。目的:对传统的形状插值方法进行改进,并运用于恒河猴脑黑质断层图像。方法:较常用的形状插值方法是对变换后的相邻两层距离图像进行线性加权平均,从而获取中间层。试验中考虑多层相邻图像空间位置对插值图像的影响,然后进行非线性加权获取中间层。结果与结论:对插值的方法进行评估,评估结果比较令人满意,并运用于恒河猴脑黑质的三维重建中。该形状插值改进方法可以较好地运用于层片稀疏且结构细微的核团插值工作中,从而为与细微结构相关的疾病研究提供一定的参考价值。

Objective:To investigate the high risk factors and methods of prevention and treatment of ovarian hyperstimulation syndrome (OHSS) in assisted reproductive techniques (ART).Methods: Clinical data of 93 cycles of OHSS patients after IVF-ET treatment from Apr. 1989to Oct. 2002 were analyzed ***: (1) A large number of follicles stimulated, luteal phase support with HCG and pregnancy were high risk factors to induce OHSS. (2) Longer disease process, more severe symptoms and more albumins used for treatment of OHSS were commonoy observed in pregnant patients with OHSS compared with non-pregnant ones. (3) Vena dropping human serum albumin is one of the most successful treatment as plasma expanders through restoration of colloid osmotic pressure; paracentesis is necessary for critical OHSS patients with severe ascites and hydrothorax;(4) Occasionally therapeutic abortion of an early gestation may be an only way for lifesaving when all other methods have ***: OHSS is a serious complication of controlled ovarian hyperstimulation. Proper prevention and treatment of OHSS are important for patient safety in ART.

Zeolite nanosheets with a short b-axis thickness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. Nevertheless, conventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-containing additives. Here, we contributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-containing ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea concentration, we achieved precise control over the crystal face aspect ratio and b-axis thickness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples consistent with those from laboratory-scale synthesis. This work marks a significant step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.

采用数值模拟方法研究了圆弧形、椭圆形和曲率连续无吸力峰前缘对叶型附面层发展的影响规律。通过提取不同工况下叶面附面层参数并结合叶表附面层速度型的变化,发现前缘吸力峰对叶型性能的影响本质在于吸力峰影响了附面层的起始发展状态。前缘吸力峰扩压参数D_(spike)过强会导致附面层起始发展状态恶化,造成提前转捩,甚至出现分离泡,叶表附面层迅速增厚,叶型损失增大,可用攻角范围减小。研究还表明,所设计的曲率连续无吸力峰前缘在任意工况总可以消除吸力面或压力面近前缘的吸力峰,从而使得叶表附面层的起始状态优于其它前缘叶型,因此气动性能要更好。
