Geospatial Information (GSI) services are a new kind of technological platform that combine accurate mapping services with real-time user location and context data. GSI can power everything from navigation to social and political engagement. Although many GSI services are already in use, little attention has been paid to the implications of the technology and the privacy concerns that it raises...

BACKGROUND AND OBJECTIVE The γ-secretase inhibitor (GSI) has been shown to inhibit expression of amyloid beta (Aβ), but GSI also has a side effect of reducing cell survival. Since low-power laser irradiation (LLI) has been known to promote cell survival, we examined whether 532 nm LLI can rescue the GSI side effect or not. STUDY DESIGN/MATERIALS AND METHODS The human-derived glioblastoma cell...

Previous studies on mice have revealed that the Griffonia simplicifolia I (GSI) lectin selectively binds to capillaries in a number of microvascular beds. These observations suggest that the lectin might be a suitable microvascular marker for physiological studies of skeletal muscle, particularly when fluorescent visualization of vessels is desired independently of their perfusion status. Since...

The Grid Security Infrastructure (GSI) proposed and implemented in Globus Toolkit has been a widely accepted solution for the security of grids in recent years. But there is no formal analysis or modelling on security mechanisms of GSI emerging in the literature yet. In this paper, we propose a formal logic, and formalize those primary security mechanisms using the logic. Our formalism not only...

the present paper studies the reproductive biology, maturation size and sex ratio of penaeus monodon collected from digha fishing grounds, india during 2011-2013.  a total of 633 individual of p. monodon were examined and among them 242 were males and 391 were females. the overall yearly sex ratio was observed to be 1:1.6 (males: females). based on the results, the spawning season of p. monodon...

Recently, Miao and Wang considered the GSI method for solving nonsingular saddle point problems and studied the convergence of the GSI method. In this paper, we prove the semi-convergence of the GSI method when it is applied to solve the singular saddle point problems.

OBJECTIVE To determine whether transthoracic three dimensional echocardiography is an accurate non-invasive technique for defining the morphology of atrial septal defects (ASD). METHODS In 34 patients with secundum ASD, mean (SD) age 20 (17) years (14 male, 20 female), the measurements obtained from three dimensional echocardiography were compared to those obtained from magnetic resonance ima...

Gridpoint statistical interpolation (GSI), a three-dimensional variational data assimilation method (3DVAR) has been widely used in operations and research in numerical weather prediction. The operational GSI uses a static background error covariance, which does not reflect the flow-dependent error statistics. Incorporating ensemble covariance in GSI provides a natural way to estimate the backg...

We examine security protocols for the Grid Security Infrastructure (GSI) version 2 and identify a weakness of poor scalability as a result of GSI’s authentication framework requiring heavy interactions between a user-side client machine and resource suppliers. We improve the GSI architecture and protocols by proposing an alternative authentication framework for GSI, which uses dynamic public/pr...
