One of the methods to diagnose rheumatoid arthritis (RA) is measuring joint space narrowing over time. A method is presented to analyze the sensitivity of this measurement to positioning of the hand. Micro-CT scans are used to generate projections of a joint under varying angles of rotation. A semi-automatic method is used to measure the joint space width (JSW) for each projection. A Statistica...

We present a case of male, premature born child with multiple anomalies. The physical status was dominated by penile duplication, with additional, abortion scrotum in the median line, without palpable content and omphalocele with semi septum of the anus. By ultrasound examination of internal organs, we found a complex congenital heart anomaly, multiple anomalies in abdomen and micro calcificati...

Recently much work has been done in lowering the Planck threshold of quantum gravitational effects (sub-millimeter dimension(s), Horava-Witten fifth dimension, strings or branes low energy effects, etc.). With a semi-classical calculation based on Hawking evaporation of planckian micro-black holes, I shall show in this paper as quantum gravity effects have to be present also at GUT energies. PA...
