We have searched for correlations between the pointing directions of ultrahigh energy cosmic rays in the data of the High Resolution Fly’s Eye (HiRes) collaboration, and local large scale structure. The HiRes stereo data set (the same used to search for AGN correlations [1]) was used in the search, and the 2 Micron All-Sky Redshift Survey (2MRS) was used to determine the density of galaxies in ...

When we view objects at various depths, the 3-D rotations of our two eyes are neurally yoked in accordance with a recently discovered geometric rule, here called the binocular extension of Listing's law; or L2. This paper examines the visual and motor consequences of this rule. Although L2 is a generalization of Listing's original, monocular law, it does not follow from current theories of the ...

Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adop...

In this study, we collected serum from 82 randomly selected patients from a rural area in Jaguapitã county, Paraná State. All sera were subjected to indirect immunofluorescence assay (IFA) to detect IgG antibodies against T. gondii. Serum titers >/=+ 16 were considered positive. Of the 82 evaluated sera, 68 (82.9%) were positive to toxoplasmosis and 14 (17.1%) were non-reactive. The most common...

In recent years, renewable energy sources have been considered the most encouraging resources for grid and off-grid power generation. This paper presents an improved current control strategy for a three-phase photovoltaic grid-connected inverter (GCI) under unbalanced and nonlinear load conditions. It is challenging to suppress the harmonic content in the output current below a pre-set value in...

BGP prefix hijacking is a sort of serious security threat of the Internet. In a hijacking attack, the attacker try to convince ASes to become infectors for redirecting data traffic to him in stead of the victim. The more infectors there are, the larger impact an attack has. It is important to understand the root of the matter why the impact of prefix hijacking differs a lot in different attacks...

Grid Datafarm (GFarm) is a Japanese national project that aims to design an infrastructure for global petascale data intensive computing. GFarm tools and APIs are provided to handle large data files in both single filesystem image and local file views. While the Grid Datafarm is originally motivated by high energy physics applications, it is a generic distributed I/O management and scheduling i...

The steered response power phase transform (SRP-PHAT) is a beamformer method very attractive in acoustic localization applications due to its robustness in reverberant environments. This paper presents a spatial grid design procedure, called the geometrically sampled grid (GSG), which aims at computing the spatial grid by taking into account the discrete sampling of time difference of arrival (...

Nowadays, data grid management systems are becoming increasingly important in the context of the recently adopted service oriented science paradigm. The Grid Relational Catalog (GRelC) project is working towards an integrated, comprehensive data grid management solution. This paper describes WebGRelC, which is a dedicated grid portal allowing data handling, publishing, discovery, sharing and or...
