We evaluate the on shell form factors of the electron for arbitrary momentum transfer and finite electron mass, at two loops in QED, by integrating the corresponding dispersion relations, which involve the imaginary parts known since a long time. The infrared divergences are parameterized in terms of a fictitious small photon mass. The result is expressed in terms of Harmonic Polylogarithms of ...

This article presents the approach and current findings of the EO2HEAVEN project, in particular from the Saxony Case Study. The aim of the Case Study is the conceptual design of a Spatial Information Infrastructure for better understanding the complex relationship between ambient air quality and its influence on the human health. This includes air quality modelling and a statistical analysis of...

This manuscript presents an overview of the current experimental situation regarding nucleon decay and the measured flux of atmospheric neutrinos. Previous and on-going experiments are reviewed, the data are presented, and new outstanding questions are posed. The SuperKamiokande project is described and its expected sensitivity for improving measurements of the nucleon lifetime and the atmosphe...

Let Ng(d) be the set of primes p such that the order of g modulo p, ordp(g), is divisible by a prescribed integer d. Wiertelak showed that this set has a natural density, δg(d), with δg(d) ∈ Q>0. Let Ng(d)(x) be the number of primes p ≤ x that are in Ng(d). A simple identity for Ng(d)(x) is established. It is used to derive a more compact expression for δg(d) than known hitherto.

The successful launch of the Landsat 8 satellite with two thermal infrared bands on February 11, 2013, for continuous Earth observation provided another opportunity for remote sensing of land surface temperature (LST). However, calibration notices issued by the United States Geological Survey (USGS) indicated that data from the Landsat 8 Thermal Infrared Sensor (TIRS) Band 11 have large uncerta...

Though stable in dilute form for very long periods of time, simple mono-emulsifier flavor emulsions based on gum acacia or modified starch are fairly limited in their ability to provide functionality beyond simple dispersion. This review highlights many of the enhancements on traditional emulsions, ranging from new materials to novel combinations of materials and processes. The development of m...

Iron based high temperature superconductors have several common features with superconducting cuprates, including the square lattice and the proximity to an antiferromagnetic phase. Themagnetic excitation spectrumbelowTc of Fe Te Se 1.02 0.7 0.3 shows an hourglass-shaped dispersionwith a resonance around the commensurate point . In a previous inelastic neutron scattering study, we showed that t...

The ability of laccases from Trametes villosa (TvL), Myceliophthora thermophila (MtL), Trametes hirsuta (ThL) and Bacillus subtilis (BsL) to improve the dispersion properties of calcium lignosulfonates 398 in the presence of HBT as a mediator was investigated. Size exclusion chromatography showed an extensive increase in molecular weight of the samples incubated with TvL and ThL by 107% and 572...

We provide a self-contained theoretical analysis of the dynamical response of a one dimensional electron system, as confined in a semiconductor quantum wire, within the random phase approximation. We carry out a detailed comparison with the corresponding two and three dimensional situations, and discuss the peculiarities arising in the one dimensional linear response from the non-existence of l...
