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)
Multidrug resistance (MDR) is a major obstacle towards a successful treatment of gastric cancer. However, the mechanisms of MDR are intricate and have not been fully understood. To elucidate the molecular mechanisms of MDR in gastric cancer, we employed the proteomic approach of isobaric tags for relative and absolute quantification (iTRAQ), followed by(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)
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)
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)
OBJECTIVE To evaluate the efficacy and safety of telbivudine (LDT) versus entecavir treatments in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients. METHODS Eighty HBeAg-positive compensated CHB patients with HBV DNA more than 6 log10 copies/ml and serum ALT 2 x ULN were divided into two groups: a telbivudine treatment group, and a(More)
Face detection plays an important role in many applications of face biometrics. With so much of digitalization, many color images and different color models have evolved in recent years. To detect a face in such image, localizing the face from other background objects have also been a challenging task. Segmenting an image based on skin color as feature had(More)
BACKGROUND Hepatitis C is a global health problem and represents a major cause of liver disease and socioeconomic burden. Effective antiviral therapy may prevent these complications, but the current treatment for patients with chronic hepatitis C virus (HCV) infection does not produce sustained virologic response. Therefore, identification of the(More)
Atherosclerosis is an inflammatory disease of the arteries. Interleukin-10 (IL-10) is known to be an anti-inflammatory cytokine which might be useful for counteracting the development of atherosclerosis. As long-term systemic cytokine delivery is prohibitively expensive, gene therapy might be a suitable approach. To test this idea, low-density lipoprotein(More)
