A procedure for both vertical canopy structure analysis and 3D single tree modelling based on Lidar point cloud is presented in this paper. The whole area of research is segmented into small study cells by a raster net. For each cell, a normalized point cloud whose point heights represent the absolute heights of the ground objects is generated from the(More)
Social behavior plays a more and more important role in delay tolerant networks (DTNs). In this paper, we present an analytical model for a hypercube-based social feature multipath routing protocol in DTNs. In this routing protocol, we use the internal social features of each node (individual) in the network for routing guidance. This approach is motivated(More)
The 37/67-kDa laminin receptor precursor (LRP)/laminin receptor (LR) is a cell surface receptor for cellular prion proteins and misfolded pathological prions. Previous research has shown that blocking or decreasing LRP/LP levels by anti-LRP/LR antibodies or small interfering RNAs (siRNAs) can prolong the incubation phase of experimental prion infection.(More)
Prion diseases are neurodegenerative disorders characterized by the accumulation of a disease-associated prion protein and apoptotic neuronal death. Previous studies indicated that the ubiquitous expression of c-Abl tyrosine kinase transduces a variety of extrinsic and intrinsic cellular signals. In this study, we demonstrated that a synthetic neurotoxic(More)
Histone deacetylase 6 (HDAC6) controls several major cellular responses to stress that play a role in neurodegenerative diseases, including aggresome formation, autophagy, and apoptosis. However, the specific role of HDAC6 in prion diseases is not known. In this study, we examined the relationship between HDAC6 and cellular response to the neurotoxic(More)
—Most routing protocols for delay tolerant networks resort to the sufficient state information, including trajectory and contact information, to ensure routing efficiency. However, state information tends to be dynamic and hard to obtain without a global and/or long-term collection process. In this paper, we use the internal social features of each node in(More)
—Delay tolerant networks (DTNs) are a kind of wireless mobile network which may lack continuous network connectivity. Multicast supports the distribution of data to a group of users, a service needed for many potential DTNs applications. While multicasting in the Internet and mobile ad hoc networks has been studied extensively, due to the unique(More)
Background and Aims It is essential to illuminate the evolutionary history of crop domestication in order to understand further the origin and development of modern cultivation and agronomy; however, despite being one of the most important crops, the domestication origin and bottleneck of soybean (Glycine max) are poorly understood. In the present study,(More)
