Connexins had been considered to be the only class of the vertebrate proteins capable of gap junction formation; however, new candidates for this function with no homology to connexins, termed pannexins were discovered. So far three pannexins were described in rodent and human genomes: Panx1, Panx2 and Panx3. Expressions of pannexins can be detected in numerous brain structures, and now found b...

Since the development of the first text-based image search on the internet, the area of image retrieval has come a long way to sophisticated content based image retrieval systems. On the other hand, the semantic gap causes that it is still not possible to create a system which can correctly identify any object in the image. However, this paper proposes a solution for classifying the one sort of...

Eckhard Hess’s claim that pupils dilate to pleasant images and constrict to unpleasant images was confounded because of inconsistent contrasts and luminances across his images. Building upon the work of Powell and Schirillo (2011) that explored multiple portraits by Rembrandt, we offer a new and promising methodology that overcomes this limitation. We presented leftwardor rightward-facing femal...

More than 100 years have passed since Wilhelm Roentgen’s discovery of x-rays, a form of electromagnetic radiation with wavelengths shorter than visible light. Roentgen’s work was the continuation of other scientists’ study of the properties of light waves. Subsequent research into particle theory by Albert Einstein and others led to the physics principles that not only laid the groundwork for s...
