Ordinal Systems, Part 2: One Inaccessible

We develop an alternative approach to well-ordering proofs beyond the Bachmann-Howard ordinal using transsnite sequences of ordinal notations and use it in order to carry out well-ordering proofs for-ordinal systems. We extend the approach of ordinal systems as an alternative way of presenting ordinal notation systems started in Set98b] and develop ordinal systems, which have in the limit exact...

Predictive Memory for an Inaccessible Environment

Inaccessible and nondeterministic environments are very common in real-world problems. One of the di culties in these environments is representing the knowledge about the unknown aspects of the state. We present a solution to this problem for the robotic soccer domain, an inaccessible and nondeterministic environment. We developed a predictive memory model that builds a probabilistic representa...

Are referred inaccessible human primary molar teeth really inaccessible?

Despite a body of compelling evidence pertaining to the root canal accessibility of primary teeth, the number of referrals for inaccessibility of primary molars is considerable. The aim of the present study was to evaluate the prevalence of true and false primary molar inaccessibility among subjects who had been referred by general and pediatric dentists. We examined 199 primary molars in 156 p...

Functioning of an arteriovenous fistula requires heme oxygenase-2.

Heme oxygenase-2 (HO-2), the constitutive isoform of the heme-degrading enzyme heme oxygenase, may serve as an anti-inflammatory vasorelaxant, in part, by generating carbon monoxide. Arteriovenous fistulas (AVFs) are employed as hemodialysis vascular accesses because they provide an accessible, high-blood-flow vascular segment. We examined the role of vascular expression of HO-2 in AVF function...

Inaccessible Varieties of Groups

A weak but still unsolved version of the first half of Problem 7 in Hanna Neumann's book [5] asks whether the product 1193 of a nontrivial join-irreducible variety VL and an arbitrary variety 93 is necessarily also join-irreducible. One of the results of this paper is a positive answer provided either It is abelian or the infiniterank free groups of IX have no nontrivial abelian verbal subgroup...
