We study amplitude zeros in radiative decay processes with a photon or a gluon emission of all possible scalar particles(e.g. scalar leptoquarks) which may interact with the usual fermions in models beyond the standard model. For the decays with a photon emission, the amplitudes clearly exhibit the factorization property and the differential decay rates vanish at specific values of a certain va...

The X-ray light curves of hundreds of bursts are now available, thanks to the X-ray Telescope on board the Swift satellite, on time scales from ∼ 1 minute up to weeks and in some cases months from the burst explosion. These data allow us to investigate the physics of the highly relativistic fireball outflow and its interaction with the circumburst environment. Here we review the main results of...

Bronchial provocation testing with methacholine was undertaken in 15 children aged 5 to 8 years with obstructive lung disease, mostly asthma (13/15). The methacholine was inhaled during two minutes of tidal breathing in increasing concentrations. After each inhalation, lung function was measured and clinical signs recorded independently by two observers unaware of each other's results. The loga...

OBJECTIVE To identify the interrelationships and discriminatory value of a broad range of objectively measured explanatory risk factors for falls. DESIGN Prospective cohort study with 12-month follow-up period. SETTING Community sample. PARTICIPANTS Five hundred community-dwelling people aged 70 to 90. MEASUREMENTS All participants underwent assessments on medical, disability, physical,...

The prevalence of type 2 diabetes is rising rapidly in all non-industrialised populations. By 2025, three-quarters of the world’s 300 million adults with diabetes will be in non-industrialised countries, and almost a third in India and China alone. There is strong evidence that this epidemic has been triggered by social and economic development and urbanisation, which are associated with genera...

We use Poincare series for massive Maass-Jacobi forms to define a "massive theta lift", and apply it the examples of constant function modular invariant j-function, with Siegel-Narain as integration kernel. These integrals are deformations known one-loop string threshold corrections. Our lifts fall off exponentially, so some Rankin-Selberg finite without Zagier renormalization.

This study investigates the phonetics of German nuclear rise-fall contours in relation to contexts that trigger either a contrastive or a non-contrastive interpretation in the answer. A rise-fall contour can be conceived of a tonal sequence of L-H-L. A production study elicited target sentences in contrastive and non-contrastive contexts. The majority of cases realized showed a nuclear rise-fal...
