Aims. The purpose of the study was to investigate the differences of adenosine, adenine, inosine, xanthine, hypoxanthine, and uric acid concentrations in patients with type 2 diabetes mellitus and diabetic retinopathy and assess the relationship between purine metabolites and disease. Materials and Methods. The study group consisted of 114 subjects which(More)
Reactive gliosis had been implicated in injury and recovery patterns associated with hydrocephalus. Our aim is to determine the efficacy of minocycline, an antibiotic known for its anti-inflammatory properties, to reduce reactive gliosis and inhibit the development of hydrocephalus. The ventricular dilatation were evaluated by MRI at 1-week post drugs(More)
Resistive switching memory cross-point arrays with TiN/HfO x /AlO y /Pt structure were fabricated. The bi-layered resistive switching films of 5-nm HfO x and 3-nm AlO y were deposited by atomic layer deposition (ALD). Excellent device performances such as low switching voltage, large resistance ratio, good cycle-to-cycle and device-to-device uniformity, and(More)
Driven by recent advances in human-centered computing, Facial Expression Recognition (FER) has attracted significant attention in many applications. In this paper, we propose a novel graphical model, multi-level Transformed Dirichlet Process (ml-TDP), for multi-pose FER. In our approach, pose is explicitly introduced into ml-TDP so that separate training(More)
Self-driving car navigation is currently attracting considerable research interests. The key problem is to guide the car to the destination in real-time with a safe and obstacle free path in real-world environments. We propose an innovative self-driving car navigation approach that incorporates a VFH (Vector Field Histogram) local path planner adapted for(More)
Innovation in hypotheses is a key transformative driver for scientific development. The conventional centralized hypothesis formulation approach, where a dominant hypothesis is typically derived from a primary phenomenon, can, inevitably, impose restriction on the range of conceivable experiments and legitimate hypotheses, and ultimately impede(More)
MicroRNA (miRNA) studies are experiencing a transition from basic research applications to clinical applications. However, the lack of reliable and sensitive miRNA detection methods has become a bottleneck in the process. Here, we report an absolute quantification method based on the competitive PCR amplification of specific miRNAs and synthetic RNA(More)
