This paper addresses flower image classification. The extent of blossom, deformation and inter-class appearance blur of flowers add great difficulties to flower classification task in addition to view, color, illumination changes that commonly occurred in other objects classification tasks. In this paper, SIFT-like feature descriptors and feature context(More)
The destination of a traditional robot navigation task is usually a static location. However, many real life applications require a robot to continuously identify and find its way toward a non-static target, e.g., following a walking person. In this paper, we present a navigation framework for this task which is based on simultaneous navigation and(More)
Risk assessment and quantification is crucial to the effectiveness of information security measure deployed in an organization. A dynamic risk assessment process is presented in this paper to cope with the variation and diversity of threats in the information system. To give a clear perspective of the information risk without confusing by the complexity of(More)
OBJECTIVE Aortic surgeries requiring hypothermic circulatory arrest evoke systemic inflammatory responses that often manifest as vasoplegia and hypotension. Because mast cells can rapidly release vasoactive and proinflammatory effectors, we investigated their role in intraoperative hypotension. METHODS We studied 31 patients undergoing proximal aortic(More)
Studies have shown that the nervous system through the modular structure simplifies control the movement, however, whether such a modular structure complexity associated with muscle coupling has not been proven well. The purpose of this study was to examine the effect of synergistic muscles and intermuscular coherence predicts muscle coordination(More)
Zr(IV) can form phosphate and Zr(IV) (-PO₃2--Zr4+-) complex owing to the high affinity between Zr(IV) with phosphate. Zr(IV) can induce the aggregation of gold nanoparticles (AuNPs), while adenosine triphosphate(ATP) can prevent Zr(IV)-induced aggregation of AuNPs. Herein, a visual and plasmon resonance absorption (PRA)sensor for ATP have been developed(More)
Aptasensors based on stripping voltammetry exhibit several advantages, such as high sensitivity and multi-target detection from stripping voltammetric technology, and high selectivity from the specific binding of apamers with targets. This review comprehensively discusses the recent accomplishments in signal amplification strategies based on nanomaterials,(More)
A novel object tracking method based on RGB-D camera is proposed to handle fast appearance change, occlusion, background clutter which may arise for vision-based robot navigation. It makes use of appearance and depth information that are complementary to each other in visual perception to get robust tracking. First, RGB image and depth information are(More)
A case-based pattern design method is proposed to translate an image into a pattern of certain style. The method has two phases. Pattern style and knowledge are learned in case-learning phase, case mapping database and rule database are results of this phase and will serve as memory unit and logical unit respectively. In design phase, user designates the(More)

The goal of the Columbia Undergraduate Law Review is to provide Columbia University and the public with an opportunity for the discussion of law-related ideas and the publication of undergraduate legal scholarship. It is our mission to enrich the academic life of our undergraduate community by providing a forum where intellectual debate, augmented by(More)
