We present results for the 2m spectroscopic part of the Multi-Site Spectroscopic Telescope campaign, which took place in May/June 2002. In order to perform an asteroseismological analysis on the multiperiodic pulsating subdwarf B star PG 1605+072 we used over 150 hours of time resolved spec-troscopy in order to search for and analyse line profile variations by using phase binning. We succeeded ...

This paper introduces a constant-time implementation for a quasi-cyclic moderate-density-parity-check (QC-MDPC) code based encryption scheme. At a 2 security level, the software takes 14 679 937 Cortex-M4 and 1 560 072 Haswell cycles to decrypt a short message, while the previous records were 18 416 012 and 3 104 624 (non-constant-time) cycles. Such speed is achieved by combining two techniques...

Our earlier renormalization group study of simplicial gravity is extended and the evidence for the existence of an isolated ultra-violet fixed point is strengthened. A high statistics study of the volume and coupling constant dependence of the cumulants of the node distribution is carried out. It appears that the phase transition of the theory is of first order, contrary to what is generally be...

Cooling down time measurements carried out at LEAR with 4.2 MeV/nucleon Pb ions and various combinations of lattice functions led to unexpected results. Notably, a finite dispersion was found to decrease strongly the horizontal cooling down times. Furthermore, intermediate betatron functions yielded shorter cooling down times than large ones and an increase of the cooler length by a factor 2 di...

The ratio of male to female sex among infants born to 391 women with and 114 079 without placenta praevia was analysed by parity. In the women without placenta praevia the sex ratio decreased significantly with increasing parity, whereas in the women with placenta praevia it increased. Overall, the sex ratio was increased among the women with placenta praevia, particularly multiparas. An increa...

Benchmark timings are presented for the fragment molecular orbital method on a Blue Gene/P computer. Algorithmic modifications that lead to enhanced performance on the Blue Gene/P architecture include strategies for the storage of fragment density matrices by process subgroups in the global address space. The computation of the atomic forces for a system with more than 3000 atoms and 44 000 bas...
