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)
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)
The representation of spatiotemporal pattern of brain electrical activity is an important issue in the research of neural assemblies. This paper describes methods of parametric 3D head or brain modeling and its corresponding interpolation for functional imaging based on brain waves. The 3D interpolation method is an extension of cortical imaging technique.(More)
BACKGROUND Triptans are a family of selective serotonin (5-HT1B/1D) receptor agonists that are widely used to treat acute migraine attacks. Their efficacy is limited by side effects and the gastrointestinal manifestations of migraine. AIM To compare the efficacy of a single intravenous administration of propacetamol, a prodrug of paracetamol(More)
Few cloud storage systems can handle random read accesses efficiently. In this paper, we present a RAMCloud Storage System, RCSS, to enable efficient random read accesses in cloud environments. Based on the Hadoop Distributed File System (HDFS), RCSS integrates the available memory resources in an HDFS cluster to form a cloud storage system, which backs up(More)
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)
BACKGROUND AND OBJECTIVE Current guidelines recommend parapneumonic effusions (PPEs) with a thickness of ≥ 10 mm be sampled via thoracentesis. We hypothesized that anteroposterior (AP) CXRs are not as sensitive as posteroanterior (PA) and lateral radiographs in identifying PPEs and should not be routinely used in patients with suspected pneumonia. METHODS(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)
