I have reviewed some of the work done describing the interaction of a superconductor and a gravitational wave. There have been proposals 1, 2, 3 that they could be used to build better gravitational wave detectors. To begin, I have summarized a paper by B. DeWitt on gravitational drag effect on superconductors 4 . Then I have reviewed the work of H. Peng et. al. on the electrodynamics of moving...
The Scotia Sea in the South Atlantic holds a prominent position in geodynamics, because it has been proposed as a potential outlet of asthenosphere from under the shrinking Pacific into the mantle beneath the opening Atlantic. Shear wave splitting and geochemical studies have previously tested this hypothesis. Here, we take a different approach by calculating presentday dynamic topography of th...
Studies on the existence of leprosy in different parts of the world have shown wide variations not only in terms of the total prevalence rate but also with regard to the type of leprosy seen ( 12). At the same time certain common trends have been noticed such as the predominance of males as compared to females and th e excess of cases among adults as compared to children. Control of leprosy dep...
— Iron 57-enriched, deoxygenated human (adult) hemoglobin (HbA), its isolated asHand /?sn-chains, and the partially iron 57-enriched, fully functional hemoglobin a2(Fe) j82(Fe) were investigated by Mossbauer spectroscopy in the temperature range 4.2 K-200 K. According to our experimental accuracy ( ± 0.006 mm s) the temperature dependent quadrupole splittings &EQ(T) of deoxygenated HbA, <XSHand...
(1) God exists in the understanding but not in reality. (Supposition) (2) Existence in reality is greater than existence in the understanding alone. (Premise) (3) God’s existence in reality is conceivable. (Premise) (4) If God did exist in reality, then he would be greater than he is (from (1) and (2)). (5) It is conceivable that there be a being greater than God is (from (3) and (4)). (6) It i...
Shear-wave splitting measurements are widely used to analyze orientations of anisotropy. We compare two different shear-wave splitting techniques, which are generally assumed to give similar results. Using a synthetic test, which covers the whole backazimuthal range, we find characteristic differences, however, in fast-axis and delay-time estimates near Null directions between the rotation corr...
In growing neutrino models, the neutrino mass increases in time and stops the dynamical evolution of a dark energy scalar field, thus explaining the ‘why now’ problem. A new attractive force, mediated by the ‘cosmon’ scalar field, makes non relativistic neutrino form lumps on the scales of superclusters and beyond. Nonlinear neutrino lumps are predicted to form at redshift z ≈ 1 and, if observe...

We show if M is a closed, connected, orientable, hyperbolic 3-manifold with Heegaard genus g then g ≥ 1 2 cosh(r) where r denotes the radius of any isometrically embedded ball in M . Assuming an unpublished result of Pitts and Rubinstein improves this to g ≥ 1 2 cosh(r) + 1 2 . We also give an upper bound on the volume in terms of the flip distance of a Heegaard splitting, and describe isoperim...
Creativity can hardly be understood in isolation from a context where values such as novelty and usefulness are ascribed. This paper presents a multi-level perspective for the study of creativity and formulates a framework for computational creativity that consists of 1) Culture; 2) Society; 3) Groups; 4) Products; 5) Personality; 6) Cognition, 7) Neural processes; and 8) CC processes. This mod...
