Let L be a relational structure. We introduce L as a synonym of L`. We now state several propositions: (1) For every relational structure L and for all elements x, y of L holds x ¬ y iff xx ­ xy. (2)...

Abstract Increasing age expectations and number of joint replacement procedures have made interprosthetic femoral fractures (IFF) a progressively more common diagnosis challenge for surgeons. A gold standard universally accepted classifications guidelines do not exist yet. Customized structured electronic searches performed in PubMed database. Relevant key terms: IFF, classification fracture, p...

A net (xα) in a Banach lattice X is said to un-converge to a vector x if ∥∥|xα−x|∧u∥∥→ 0 for every u ∈ X+. In this paper, we investigate un-topology, i.e., the topology that corresponds to un-convergence. We show that un-topology agrees with the norm topology iff X has a strong unit. Un-topology is metrizable iff X has a quasi-interior point. Suppose that X is order continuous, then un-topology...

I canvass eight possible approaches to representing ambiguity within truth-conditional semantics, and I argue that all are unsatisfactory. For example, it would be a mistake to hold that "x is a bank" is true iff x is a financial institution while "x is a bank" is true iff x is a slope, for then x would be a financial institution iff x is a slope. It would also be a mistake to hold that some to...

Let α1 be a formula from N5 logic, and let α2 be the formula that is obtained from α1 by replacing conjunction, disjunction and implication by respectively a t-norm ⊗, a t-conorm ⊕ and an implicator →. Noting that V − 2 (w, a) ∈ {0, 1} and V + 2 (w, a) ∈ {0, 1} for all a ∈ At and w ∈ {h, t}, it follows easily from the definitions (17)–(23) that V1(w,α1) = 1 iff V2(w,α2) = [1, 1], V1(w,α1) = 1 i...
