Load balancing in the cloud computing environment has an important impact on the performance. Good load balancing makes cloud computing more efficient and improves user satisfaction. This article introduces a better load balance model for the public cloud based on the cloud partitioning concept with a switch mechanism to choose different strategies for(More)
Progesterone plays a role in breast cancer development and progression but the effects on breast cancer cell movement or invasion have not been fully explored. In this study, we investigate the actions of natural progesterone and of the synthetic progestin medroxyprogesterone acetate (MPA) on actin cytoskeleton remodeling and on breast cancer cell movement(More)
BACKGROUND Limited information is available on the effects of progestins on breast cancer progression and metastasis. Cell migration and invasion are central for these processes, and require dynamic cytoskeletal and cell membrane rearrangements for cell motility to be enacted. METHODS We investigated the effects of progesterone (P), medroxyprogesterone(More)
Ubiquitous access to sophisticated internet services from diverse end devices across heterogeneous networks requires the injection of additional functionality into the network to handle protocol conversion, data transcod-ing, and in general bridge disparate network portions. Several researchers have proposed infrastructures for injecting such functionality;(More)
BACKGROUND Estrogen is an established enhancer of breast cancer development, but less is known on its effect on local progression or metastasis. We studied the effect of estrogen receptor recruitment on actin cytoskeleton remodeling and breast cancer cell movement and invasion. Moreover, we characterized the signaling steps through which these actions are(More)
BACKGROUND The elevated expression of vascular endothelial growth factor C (VEGF-C) is correlated with clinical cervical cancer metastasis and patient survival, which is interpreted by VEGF-C functions to stimulate angiogenesis and lymphatic genesis. However, the direct impact of VEGF-C on cervical cancer cell motility remains largely unknown. METHODS In(More)
This paper describes an adaptive network infrastructure, Composable Adaptive Network Services (CANS), for bridging the bandwidth and resource gap between network services and mobile clients. CANS enables construction of service access paths augmented with 'impedance matching' components that handle operations such as caching, protocol conversion, and(More)
Source authentication is the most important and difficult problem in multicast security, and no schemes can satisfy all multicast applications. So a hybrid multicast source authentication (HMSA) scheme was proposed based on two data structures: hashing tree and hashing chain. Compared with some other schemes in computation and communication overheads, HMSA(More)
Estrogens are important regulators of neuronal cell morphology, and this is thought to be critical for gender-specific differences in brain function and dysfunction. Dendritic spine formation is dependent on actin remodeling by the WASP-family verprolin homologous (WAVE1) protein, which controls actin polymerization through the actin-related protein(More)
