The 007 benchmark provides a comprehensive test of OODB (Object-Oriented Data Base) performance. In this paper, we discuss the problems and the possible suggestions for the 007 Benchmark, based on our experience, in terms of performance evaluation of OODB concurrency control techniques. Our discussions are focused on three access types of OODB concurrency control techniques: conflict among meth...

A controversy at the  IUCN World Conservation Congress on the topic of closing domestic ivory markets (the , or so-called James Bond, motion) has given rise to a debate on IUCN’s value proposition. A cross-section of authors who are engaged in IUCN but not employed by the organization, and with diverse perspectives and opinions, here argue for the importance of safeguarding and strengthe...

BACKGROUND Glioblastoma multiforme, a World Health Organization grade IV glioma, has a poor prognosis in humans despite current treatment options. Here, we present magnetic resonance imaging (MRI) data regarding the regression of aggressive rat F98 gliomas and human U87 glioma xenografts after treatment with the nitrone compound OKN-007, a disulfonyl derivative of α-phenyl-tert-butyl nitrone. ...

In order to contribute to solve the personalization/privacy paradox, we propose a privacy-preserving architecture for one of stateof-the-art recommendation algorithm, Slope One. More precisely, we describe SlopPy (for Slope One with Privacy), a privacy-preserving version of Slope One in which a user never releases directly his personal information (i.e, his ratings). Rather, each user first per...

We consider two-stage scattered data fitting with truncated hierarchical B-splines (THB-splines) for the adaptive reconstruction of industrial models. The first stage scheme is devoted to computation local least squares variational spline approximations, exploiting a simple fairness functional handle distributions locally varying density points. Hierarchical quasi-interpolation based on THB-spl...

This study investigated the effects of delay of reinforcement on the classroom academic behaviors (rate of increase and accuracy of mathematical problem coapletion) by elementary students. A total of 11 fourth graders with a history of low achievement in arithmetic were divided into two groups and given timed arithmetic tests daily. Three reinforcement conditions were used (immediate, 1-day del...

Introduction: An achondrite, Dhofar 007 (~27 kg) was found in the Oman desert and was initially classified as a cumulate eucrite [1]. However, Yamaguchi et al. [2] showed that a coarse-grained clast (CG clast) in Dhofar 007 has a high abundance of metallic phases and the high bulk Ni and Co contents, and suggested a possible relationship with mesosiderites. We performed an additional petrologic...
