Uncertainty in expert systems and credit granting decisions
One of the most popular utilization of expert systems is supporting credit granting decisions. Usually, certain systems without possibilities of representing of uncertain knowledge are used. The main aim of this paper is to compare certain and uncertain expert systems supporting credit granting decisions, and stating which one is superior over another
Supporting of legal decisions
Producers of legal software most frequently offer legal texts explorers with no possibilities ofinterpreting legal acts. Therefore, one of the aims of this work is to create and research a toolwhich could help actively to avoid the user’s necessity to interpret the legal text. Another aim ofthe work is selection of a suitable legal base, and analysis of possibilities of realization of expertsystem supporting legal decisions

Double universality of a quantum phase transition in spinor condensates: the Kibble-\.Zurek mechanism and a conservation law
We consider a phase transition from antiferromagnetic to phase separated
ground state in a spin-1 Bose-Einstein condensate of ultracold atoms. We
demonstrate the occurrence of two scaling laws, for the number of spin
fluctuations just after the phase transition, and for the number of spin
domains in the final, stable configuration. Only the first scaling can be
explained by the standard Kibble-\.Zurek mechanism. We explain the occurrence
of two scaling laws by a model including post-selection of spin domains due to
the conservation of condensate magnetization
Coronary artery bypass grafting in patients with relatively recent previous stent implantation: Three years follow-up results
Background: An increasing number of patients who undergo coronary artery bypass grafting(CABG) have a history of coronary stent implantation. This study aims to assess perioperative
and medium-term follow-up outcomes in patients in whom CABG was preceded by coronary
stent implantation within two years before operation.
Methods: One hundred and sixty two patients undergoing CABG after previous stent placement
(PCI + CABG group) were compared to 149 who had CABG without PCI in the past
(CABG group). Clinical, angiographic and perioperative outcome data were compared. The
three year follow-up comprised data on number of deaths and the presence of anginal symptoms.
Results: In both groups the extent of coronary artery disease was comparable, but more
patients in the PCI + CABG group had a history of myocardial infarction. Perioperative
outcome data did not differ between the groups except for a higher number of vessels considered
infarct-related grafted in the CABG group. Patients operated on up to three months after PCI
had more extensive coronary heart disease than those operated on later. They also had
a significantly shorter operation time. This group also showed a trend towards less postoperative
bleeding, less rethoracotomy and less low cardiac output syndrome. In a three year
follow-up, 48 (30%) patients in the PCI + CABG group reported presence of angina compared
to 28 (19%) in the CABG group (p = 0.04).
Conclusions: Previous PCI does not significantly influence the CABG outcome. In mediumterm
follow-up, freedom from anginal symptoms is less likely in patients in whom CABG was
preceded by stent implantation
