We just started an observational program to obtain 2D kinematics of nuclear bars, to be compared to N body simulations of single and double-barred galaxies. We have started a program to study the kinematics of double-barred galaxies using the Integral Field Spectrograph OASIS (CFHT). Stellar bidimensional velocity fields obtained with OASIS are compared with N body + SPH simulations, to constra...

Dear Editor: Since the publication of Objective Assessment of Skills in Intraocular Surgery (OASIS) in 2005, we have received numerous requests from academic institutions and private surgeons both in the United States and abroad requesting inclusion in the OASIS database as well as updated templates to assess patient outcomes objectively. As we continue to establish a centralized database for a...

OBJECTIVE To evaluate the self-perceived orthodontic treatment need in a university population evaluated through 3 scales that used different approaches. DESIGN Cross-sectional survey. SETTING University dental clinic, Lima, Peru, 2001. MATERIALS AND METHODS Questionnaires that gathered perceptions on dentofacial aesthetic perception and orthodontic treatment need were applied to a random...

Net primary productivity (NPP) of the vegetation in an oasis can reflect capacity a plant community under natural environmental conditions. Owing to extreme arid climate conditions and scarce precipitation regions, groundwater plays key role restricting development vegetation. The Qira Oasis is located on southern margin Taklimakan Desert (Tarim Basin, China) that one most vulnerable regions re...

Marine biotoxins are algal metabolites that can accumulate in fish or shellfish and render these foodstuffs unfit for human consumption. These toxins, released into seawater during algal occurrences, can be monitored through passive sampling. Acetone, methanol and isopropanol were evaluated for their efficiency in extracting toxins from algal biomass. Isopropanol was chosen for further experime...

Liquid and solid precipitation is abundant in the high elevation, upper reach of the Heihe River basin in northwestern China. The development of modern irrigation schemes in the middle reach of the basin is taking up an increasing share of fresh water resources, endangering the oasis and traditional irrigation systems in the lower reach. In this study, the response of vegetation in the Ejina Oa...

Learning a measure of similarity between pairs of objects is an important generic problem in machine learning. It is particularly useful in large scale applications like searching for an image that is similar to a given image or finding videos that are relevant to a given video. In these tasks, users look for objects that are not only visually similar but also semantically related to a given ob...

Wireless sensor networks consist of small, inexpensive devices which interact with the environment, communicate with each other, and perform distributed computations in order to monitor spatio-temporal phenomena. These devices are ideally suited for a variety of applications including object tracking, environmental monitoring, and homeland security. At present, sensor network technologies do no...

Learning a measure of similarity between pairs of objects is a fundamental problem in machine learning. It stands in the core of classification methods like kernel machines, and is particularly useful for applications like searching for images that are similar to a given image or finding videos that are relevant to a given video. In these tasks, users look for objects that are not only visually...
