Starting from the standard feature vector representation, we study ...

Most of current Video Copy Detection systems (VCD) perform a multimodal detection by dividing the system into subsystems. Each subsystem performs a copy detection using a different feature (either visual or audio), and the sets of candidates are combined (fused) to create the final result. We present a VCD system that fuses visual and audio descriptors at the similarity search level. The system...

background: recent studies demonstrated that resveratrol has many therapeutic effects on liver disorders. resveratrol significantly increased survival after liver transplantation, decreased fat deposition, necrosis, and apoptosis which induced by ischemia in wistar rats. it provided liver protection against chemical, cholestatic, and alcohol injury. resveratrol can improve glucose metabolism an...

Objective: To develop a set of descriptive terms applied to the sensation of dyspnea (dyspnea descriptors) for use in Brazil and to investigate the usefulness of these descriptors in four distinct clinical conditions that can be accompanied by dyspnea. Methods: We collected 111 dyspnea descriptors from 67 patients and 10 health professionals. These descriptors were analyzed and reduced to 15 ba...

Quantitative Structure-Property Relationship (QSPR) models for modeling and predicting thermodynamic properties such as the enthalpy of vaporization at standard condition (ΔH˚vap kJ mol-1) and normal temperature of boiling points (T˚bp K) of 57 mono and Polycyclic Aromatic Hydrocarbons (PAHs) have been investigated. The PAHs were randomly separated into 2 groups: training and test sets. A set o...

We introduce a new method that characterizes quantitatively local image descriptors in terms of their distinctiveness and robustness to geometric transformations and brightness deformations. The quantitative characterization of these properties is important for recognition systems based on local descriptors because it allows for the implementation of a classifier that selects descriptors based ...

OBJECTIVE Cumulative data suggest that central sensitization may contribute to pain in osteoarthritis (OA) and present with symptoms typically associated with neuropathic pain (NP). We evaluated the responses from focus group participants on the knee OA pain experience for pain descriptions that suggest NP. METHODS Focus group transcripts were analyzed by 2 independent assessors for unprompte...
