As sibling cases of one and the same family showed almost complete similarities in their clinical and pathological findings with uniform biochemical disturbances, it may safely be asserted that the disease is inherited in a single factor. As for the genetic ratio, the difference between the value calculated from the Haldane's formula and the theoretical value 0.25 proved statistically insignifi...

Sir, The recent paper of Siristatidis and Bhattacharya (2007) argues that the term unexplained infertility (UI) appears sustainable from a clinical and practical perspective, in spite of some fuzziness. I agree with this conclusion having in mind complicated multi-step processes of gametogenesis, meiosis and fertilization. The UI term leaves a door open for diverse unexpected scenarios of repro...

Structural relaxation in binary hard spherical particles has been shown recently to exhibit a wealth of remarkable features when size disparity or mixture composition is varied. In this paper, we test whether or not similar dynamical phenomena occur in glassy systems composed of binary hard ellipses. We demonstrate via event-driven molecular dynamics simulation that a binary hard-ellipse mixtur...

We present a method to design binary diffractive microlenses with subwavelength structures, based on the finite-difference time-domain method and the genetic algorithm, also accounting for limitations on feature size and aspect ratio imposed by fabrication. The focusing efficiency of the microlens designed by this method is close to that of the convex lens and much higher than that of the binar...
