The reduction of hippocampal volume remains controversial in depression because of the variability among individuals in clinical studies. Here, a reliable experimental rat model of depression, established by chronic unpredictable mild stress (CUMS), was used. Thirty rats were randomly divided into two groups (CUMS group and control group). Hippocampal(More)
Spatial-keyword queries on road networks are receiving increasing attention with the prominence of location-based services. There is a growing need to handle queries on road networks in distributed environments because a large network is typically distributed over multiple machines and it will improve query throughput. However, all the existing work on(More)
Query (e.g., shortest path) on road networks has been extensively studied. Although most of the existing query processing approaches are designed for centralized environments, there is a growing need to handle queries on road networks in distributed environments due to the increasing query workload and the challenge of querying large networks. In this(More)
Macrophage migration inhibitory factor (MIF) is important in regulating cell proliferation and apoptosis in both normal and cancerous cells, and may be important in cancer progression and metastasis. In human non-small cell lung cancer (NSCLC), the underlying mechanisms responsible for MIF-dependent regulation of cellular proliferation, and cell death(More)
The IP SANs have gained widespread applications for their low deployment cost, but the performance of IP SANs is an issue that people have long been concerned about. Caching data on fast devices will improve the overall performance of an IP SAN system. This paper presents a cache system which is hosted on the iSCSI target. The system uses the DRAM memory on(More)
In this paper, we consider the joint optimization of resource allocation in wireless backhaul links and user-centric clustering in the access links. The objective is to maximize the weighted sum rate (WSR) of all users under the backhaul resource constraints. To solve this intractable problem, we adopt the &#x2113;<sub>1</sub>-norm approximation approach to(More)
