Ochratoxin A(OTA) is found to be one of the predominant contaminating mycotoxins in a wide variety of food commodities. To avoid the risk of OTA consumption, the detection and quantitation of OTA level are of great significance. Based on the fact that ssDNA aptamer has the ability to form a double-strand structure with its complementary sequence, a simple(More)
Virtualization and cloud computing technologies now make it possible to consolidate multiple online services, which are packed in Virtual Machines (VMs), into a smaller number of physical servers. However, it is still a challenging scheduling problem for cloud provider to dynamically manage the VM allocation for handling variable workloads without Service(More)
Since Internet of Things (IoT) applications are deployed within open physical environments, their executions suffer from a wide spectrum of uncertain factors (e.g., network delay, sensor inputs). Although ThingML is a promising IoT modeling and specification language which enables the fast development of resource-constrained IoT applications, it lacks the(More)
The reproductive system is sensitive to lead (Pb) toxicity, which has long been an area of research interest, but the underlying mechanisms remain to be illustrated. Peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) is pivotal in mitochondrial function. In this study, mouse testis Sertoli cells (TM4 cells), PGC-1α lower-expression(More)
This paper, on rural restructuring in China, focuses on the ability of agricultural heritage systems to adapt to modernizing conditions in the rural economy. Since 2002, when FAO initiated the protection of Globally Important Agricultural Heritage Systems (GIAHS), the value of agricultural heritage has been widely acknowledged, as has the importance and(More)
Lysine specific demethylase 1 plays a crucial role in regulating histone methylation at residues K4 and K9 on histone H3 and over-expresses in a variety of cancers. Here we designed, synthesized and evaluated a series of N-(3-substituted-phenyl)benzenesulfonamides as reversible lysine specific demethylase 1 inhibitors. All the compounds exhibited lysine(More)
We designed an interactive 3D user interface system to perform object modeling in virtual environments. Expanding on existing 3D user interface techniques, we integrate low-cost human gesture recognition that endows the user with powerful abilities to perform complex virtual object modeling tasks in an immersive game setting. Much research has been done to(More)
