Variable stars magnitudes estimations exploiting the eye physiology
Variable the eye physiology
2011/9/29
The physiology of the dark adaption process of the eye is revisited from an astronomical point of view. A new method for the magnitude estimation of a star is presented. It is based upon the timing of...
Can Maxwell's Fish Eye Lens Really Give Perfect Imaging? Part II. The case with drains
Maxwell's Fish Eye Lens Perfect Imaging Part II
2010/11/16
We use both FEM (finite element method) and FDTD (finite difference time domain method) to simulate the field distribution in Maxwell's fish eye lens with one or more passive drains around the image ...
Final Results from the High Resolution Fly's Eye (HiRes) Experiment
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/4
Final results from the High Resolution Fly's Eye (HiRes) on the observation of the Greisen-Zatsepin-Kuzmin cutoff in the cosmic ray spectrum are presented. We observe a cutoff consistent with the GZK ...
Typhoon eye trajectory based on a mathematical model: comparing with observational data
Typhoon eye trajectory observational data
2010/4/2
We propose a model based on the primitive system of the Navier-Stokes equations in a bidimensional framework as the $l$ - plane approximation, which allows us to explain the variety of tracks of tropi...
Switch and template pattern formation in a discrete reaction diffusion system inspired by the Drosophila eye
Switch template pattern formation discrete reaction diffusion Drosophila eye
2010/4/1
We examine a spatially discrete reaction diffusion model based on the interactions that create a periodic pattern in the Drosophila eye imaginal disc. This model is capable of generating a regular hex...

MIT researchers spotlight brain waves
2009/8/18
Researchers at MIT's Picower Institute for Learning and Memory say you are more likely to scan the room, jumping from face to face as you search for your friend. In addition, the timing of these jumps...
A technique for producing extremely smooth patterns has doubled the distance that surface plasmons can travel on metal films, according to researchers in the US. The “template stripping” approach also...
