in the United Kingdom of those days. There was a time when Sir Robert Peel, the Prime Minister was told by a President of one of the then Royal Colleges: "No man who has an academic education ought to practise obstetrics." The same gentleman stated amidst applause in a subsequent meeting: "Obstetrics is no calling for a gentleman". The story in the book tells us how in 1946 in the same kingdom ...

We solve for the effective actions on the Coulomb branches of a class of N = 2 supersymmetric theories by finding the complex structure of an M5 brane in an appropriate background hyperkahler geometry corresponding to the lift of two O6 orientifolds and four D6 branes to M theory. The resulting Seiberg-Witten curves are of finite genus, unlike other solutions proposed in the literature. The sim...

Introduction: The light reflected from planetary surfaces and measured by remote sensing instruments is affected not only by the composition of the surface but by the physical structure of the surface. The structure of the surface is characterized by both endogenic and exogenic processes. We investigate the effects of these processes on the surfaces of the icy Saturnian satellites using photome...

BACKGROUND ROC curves have become the standard for describing and comparing the accuracy of diagnostic tests. Not surprisingly, ROC curves are used often by clinical chemists. Our aims were to observe how the accuracy of clinical laboratory diagnostic tests is assessed, compared, and reported in the literature; to identify common problems with the use of ROC curves; and to offer some possible s...

this type. KHSO4 affords a notable example where three curves of this type meet in a triple point. For a liquid, As always decreases with increasing temperature on either a rising or a falling curve. On the rising transition curves there are 37 cases of normal variation of Av and 5 of abnormal variation; on the falling curves 8 normal and 8 abnormal cases. The relative compressibility, thermal ...

STOCHASTIC SYNCHRONY AND PHASE RESETTING CURVES: THEORY AND APPLICATIONS Sashi K. Marella, PhD University of Pittsburgh, 2012 We investigate the relationship between the shape of the phase-resetting curve (PRC) and the degree of stochastic synchronization observed between a pair of uncoupled general oscillators receiving partially correlated Poisson inputs. Using perturbation methods, we derive...

The phase-response curve (PRC) is an important tool to determine the excitability type of single neurons which reveals consequences for their synchronizing properties. We review five methods to compute the PRC from both model data and experimental data and compare the numerically obtained results from each method. The main difference between the methods lies in the reliability which is influenc...

Phase response curves (PRCs) have become an indispensable tool in understanding the entrainment and synchronization of biological oscillators. However, biological oscillators are often found in large coupled heterogeneous systems and the variable of physiological importance is the collective rhythm resulting from an aggregation of the individual oscillations. To study this phenomena we consider...

We predict how a remote observer would see the brightness variations of giant planets similar to those in our Solar System as they orbit their central stars. We model the geometry of Jupiter, Saturn and Saturn’s rings for varying orbital and viewing parameters. Scattering properties for the planets and rings at wavelenghts 0.6-0.7 microns are assumed to follow these observed by Pioneer and Voya...
