The orbital parameters of extra-solar planets have a significant impact on the probability that the planet will transit the host star. This was recently demonstrated by the transit detection of HD 17156b whose favourable eccentricity and argument of periastron dramatically increased its transit likelihood. We present a study which provides a quantitative analysis of how these two orbital parame...

In this paper, we compute the scattering matrix for the Hilbert modular group over any number field K. We then express the determinant of the scattering matrix as a ratio of completed Dedekind zeta functions associated to the Hilbert class field of K. This generalizes work of Efrat and Sarnak [ES] in the imaginary quadratic case.

The gastrointestinal (GI) transit and absorption of orally administered theophylline, a highly absorbable drug without presystemic elimination, were investigated under fasted and fed conditions using three rats in a crossover study. To evaluate the GI transit rate for each segment in vivo, a noninvasive technique, gamma scintigraphy, was employed using a nonabsorbable compound, (99m)Tc-labeled ...

BACKGROUND To quantitatively evaluate radiation-induced impaired oesophageal transit with oesophageal transit scintigraphy and to assess the relationships between acute oesophagitis symptoms and dysmotility. METHODS Between January 1996 and November 1998, 11 patients affected by non-small-cell carcinoma of the lung not directly involving the oesophagus, requiring adjuvant external beam radiot...

There is a unique solution of the planet and star parameters from a planet transit light curve with two or more transits if the planet has a circular orbit and the light curve is observed in a band pass where limb darkening is negligible. The existence of this unique solution is very useful for current planet transit surveys for several reasons. First, there is an analytic solution that allows ...

A chronically high blood pressure (BP) may lead to arteriosclerosis and consequently is a risk factor for apoplectic stroke and cardiac infarction – the main death causes in industrial countries. Hence, blood pressure recently has become one of the most relevant parameters for the assessment of a patients’ health status. For the purpose of a continuous monitoring of cardiovascular patients, we ...
