1 The hard X-ray flux ratio ℜ of the footpoint sources to the loop-top source has been used to investigate non-thermal electron trapping and precipitation in solar flares. Considering the mission-long Yohkoh Hard X–ray Telescope database, from which we selected 117 flares, we investigated a dependence of the ratio ℜ on flare loop parameters like height h and column depth N. We used non-thermal ...

Simple modifications are introduced to the evolvable self-reproducing CA (Evoloop) implemented by Sayama [4] with the aim of mimicking a predator-prey model. A new state to represent the predator (disease) and a corresponding rule set are added to the CA, as well as a memory layer to track predator lifetime. Behaviour of the modified system is investigated and compared for different choices of ...

We have contrived the evoloop 5, 6 , a new selfreproducing loop spontaneously evolving on a simple deterministic 9-state 5-neighbor cellular automata (CA) space. In this article, we examine the evolvability and adaptability of the evoloop through several experiments, the result of which brings us good prospects for the future implementation of an extraordinary large-scale arti cial ecosystem on...

The article presents 5 cases of IUD translocation in women aged 27-34; 3 of the devices were Copper-7; the others were a Copper-T and Lippes Loop. In all cases the devices' strings were missing and the devices had been localized through X-rays and sometimes through a hystero-salpingogram. The devices were removed by laparoscopy in 3 cases, and by laparotomy in 2 cases. IUD translocation is u...

The main result of this paper is the determination of all nonassociative Moufang loops of orders *31. Combinatorial type methods are used to consider a number of cases which lead to the discovery of 13 loops of the type in question and prove that there can be no others. All of the loops found are isomorphic to all of their loop isotopes, are solvable, and satisfy both Lagrange's theorem and Syl...

Context. The common flare scenario comprises an acceleration site in the corona and particle transport to the chromosphere. Using satellites available to date it has become possible to distinguish between the two processes of acceleration and transport, and study the particle propagation in flare loops in detail, as well as complete comparisons with theoretical predictions. Aims. We complete a ...
