We propose a method for vector field learning with out-liers, called vector field consensus (VFC). It could distinguish inliers from outliers and learn a vector field fitting for the inliers simultaneously. A prior is taken to force the smoothness of the field, which is based on the Tiknonov regularization in vector-valued reproducing kernel Hilbert space.(More)
Security testing has gained significant attention recently due to frequent attacks against software systems. This paper presents a trace-based security testing approach. It reuses test cases generated from previous testing methods to produce execution traces. An execution trace is a sequence of program statements exercised by a test case. Each trace is(More)
Complex Event Processing (CEP) over event streams has become increasingly important for real-time applications ranging from healthcare to supply chain management. In such applications, arbitrarily complex sequence patterns as well as non existence of such complex situations must be detected in real time. To assure real-time responsiveness for detection of(More)
This paper introduces a class of adaptive Perona-Malik (PM) diffusion, which combines the PM equation with the heat equation. The PM equation provides a potential algorithm for image segmentation, noise removal, edge detection, and image enhancement. However, the defect of traditional PM model is tending to cause the staircase effect and create new features(More)
A new series of 7-O-substituted pyridyl-4-methyl coumarin derivatives were synthesized and characterized based on their spectral data. All the target compounds were evaluated for their in vitro antifungal activity against eight important fungal pathogens. This study showed that the introduction of the substituted pyridyl moiety at the 7-hydroxy position of(More)
The adoptive transfer of antigen-specific cytotoxic T lymphocytes (CTL) shows promise in the treatment of cancer and infectious diseases. We utilize adeno-associated virus-(AAV-) based antigen gene-loaded dendritic cells (DCs) to stimulate such antigen-specific CTL. Yet further improvements in CTL stimulation and killing may result by gene delivery of(More)
