We present a review of the Bielefeld-Dubna activities on multiloop calculations. In the first contribution of the above authors in these proceedings, we have introduced our system for the automation of evaluation of Feynman diagrams, called DIANA (DIagram ANAlyser). In this contribution methods for the evaluation of scalar two-loop integrals will be discussed. 1 Expansion of three-point functio...

BACKGROUND Progressive bulbar palsy (PBP) is a classic phenotype of bulbar onset amyotrophic lateral sclerosis (ALS) with more rapid progression and worse prognosis. However, as an often under-understood variant of ALS, isolated bulbar palsy (IBP) appears to progress more slowly and has a relatively benign prognosis. This study aimed to investigate the natural course and clinical features of IB...

Magnetic reconnection is a complex mechanism that converts magnetic energy into particle kinetic and plasma thermal in space astrophysical plasmas. In addition, turbulence appear to be intimately related We analyze the magnetic-field at exhaust of four events detected solar wind using Jensen-Shannon complexity-entropy index. The interplanetary field decomposed LMN coordinates hybrid minimum var...

where ci is the D-dimensional vector of the ith link, and i ­ 1, . . . , b. The right-hand side of Eq. (1) is the LBGK collision integral Di , the function N eq i is the local equilibrium, and v $ 0 is a dimensionless parameter. As the state of the lattice is updated long enough, the dynamics of Ni becomes governed by macroscopic equations for a finite system of local averages. Depending on the...

A nearly complete and undisturbed Miocene carbonate sequence is present in the easternmost part of the UmbriaMarche basin, Italy, which is ideal for detailed and integrated stratigraphic investigations of the Miocene Epoch. In this study, we were trying to obtain evidence for the presence or absence of distal ejecta from the 15 Ma Ries impact structure in southern Germany, located about 600 km ...

In this paper we show that, for each Ekedahl-Oort stratum contained in the supersingular locus, the number of its irreducible components is equal to a class number of a quaternion unitary group. MSC: primary: 14K10; secondary: 11G10; 14L05
