: Although adipose-derived stem cells (ASCs) hold the promise of effective therapy for myocardial infarction, low cardiac retention of implanted ASCs has hindered their therapeutic efficiency. We investigated whether an externally applied static magnetic field (SMF) enhances cardiac localization of "magnetic" cells and promotes heart function recovery when(More)
In Infrastructure-as-a-Service clouds, virtual machine provisioning time is an important metric for evaluating the quality of service (QoS) provided by the service providers. VM provisioning is usually time-consuming, especially when many VMs boot up simultaneously. We call such phenomenons “Boot Storm”. In practice, many VMs would run on a single compute(More)
Both cloud computing and desktop virtualization are based on massive virtual machines (VMs). Due to the conventional template-based creation and the limited bandwidth of disk I/O, booting up massive VMs is time consuming and lacks flexibility as well. However, current solutions put their focus on the design of the distributed storage for massive VMs'(More)
