Performance isolation is a key requirement for application-level multi-tenant sharing hosting environments. It requires knowledge of the resource consumption of the various tenants. It is of great importance not only to be aware of the resource consumption of a tenant's given kind of transaction mix, but also to be able to be aware of the resource(More)
Platelets play an essential role in hemostasis and atherothrombosis. Owing to their short storage time, there is constant demand for this life-saving blood component. In this study, we report that it is feasible to generate functional megakaryocytes and platelets from human embryonic stem cells (hESCs) on a large scale. Differential-interference contrast(More)
Expansin protein is a component of the cell wall generally accepted to be the key regulator of cell wall extension during plant growth. Plant hormones regulate expansin gene expression as well as plant growth during drought stress. However, the relationship between expansin and plant hormone is far from clear. Here, we studied the involvement of expansin in(More)
Cloud computing provide scalability and high availability for web applications using such techniques as distributed caching and clustering. As one database offloading strategy, elastic caching platforms (ECPs) are introduced to speed up the performance or handle application state management with fault tolerance. Several cache strtegies for ECPs have been(More)
OBJECTIVE To observe the effect of small dose donepezil (Aricept) on the cognition status and the changes of metabolites in brain tissue in patients with amnestic mild cognitive impairment (aMCI) in order to find out the effective way to prevent and cure dementia. METHODS 33 patients with aMCI were selected. There were 21 cases in a treatment group taking(More)
Although the study of imprinted genes in human development is very important, little is known about their expression and regulation in the early differentiation of human tissues due to lack of an appropriate model. In this study, a Chinese human embryonic stem (hES) cell line, SHhES1, was derived and fully characterized. Expression profiles of human(More)
E-commerce systems are typically QoS-sensitive, so QoS-oriented tunings of e-commerce servers are very important for such systems. However, existing e-commerce benchmarks are insufficient for supporting QoS-oriented tunings, because some critical QoS features of e-commerce systems cannot be precisely evaluated by them. One example of these features is the(More)
BACKGROUND The etiology of birth defects has been widely studied but is not yet fully clarified, previously published data had suggested that maternal age or parity maybe involved, but without consistent conclusions. METHODS A population-based, case-control study was nested in a cohort of perinatal infants born from 2010 to 2012 in Baoan District,(More)
With the rapid development of cloud computing, traditional TP applications are evloving into the Extreme Transaction Processing (XTP) applications which are characterized by exceptionally demanding performance, scalability, availability, security, manageability and dependability require requirements, elastic caching platforms (ECPs) are introduced to help(More)
The problem of load rebalancing is an important issue for cloud-based key-value stores. However, the new virtualization environment and the store's stateful feature make this classical issue more challenging. In this paper, we build a new load rebalancing framework for cloud-based key-value stores, namely ElastiCat. It can be used for auto reconfiguring the(More)
