An AmpC-type beta-lactamase conferring high-level resistance to expanded-spectrum cephalosporins and monobactams was characterized from an Acinetobacter baumannii clinical isolate. This class C beta-lactamase (named ADC-33) possessed a Pro210Arg substitution together with a duplication of an Ala residue at position 215 (inside the Omega-loop) compared to a reference AmpC cephalosporinase from A...

We estimate random-parameter logit models of anglers' choice of fishing site. The models generalize logit by allowing coefficients to vary randomly over anglers rather than being fixed. The models do not exhibit the restrictive "independence from irrelevant alternatives property" of logit and can represent any substitution pattern. Estimation explicitly accounts for the fact that the variation ...

In an influential article Tornell and Lane (1999) considered an economy, populated by multiple powerful groups, in which property rights in the formal sector are not protected. They argued that then investment in an informal sector may be optimal and set up conditions for “voracity” such that a permanent positive shock in the formal sector leads to lower economic growth. Here I show that whenev...

In this paper, the dependence spaces are discussed for textural formal concepts considering method given by Ma et al. A complete congruence on a lattice is an equivalence relation if it satisfies infinite substitution property. More generally, join-dependence and meet-dependence space with respect to domain of discourse presented. Using duality in textures, closure interior operators defined ob...

Abstract Foundations are provided for rank-dependent preferences within the popular two-stage framework of Anscombe–Aumann, in which risk and ambiguity feature as distinct sources uncertainty. We advance study attitudes towards without imposing expected utility risk. As a result, our general model, attitude can be captured by non-additive subjective probabilities under Choquet or specific recur...

We present an extension of the ( )-calculus with a case construct that propagates through functions like a head linear substitution, and show that this construction permits to recover the expressiveness of ML-style pattern matching. We then prove that this system enjoys the Church-Rosser property using a semi-automatic `divide and conquer' technique by which we determine all the pairs of commut...

The morpholine and piperazine with their remarkable physical and biochemical properties are popular heterocycles in organic and medicinal chemistry used in rational property design. However, in the majority of cases these rings are added to an existing molecule in a building block approach thus limiting their substitution pattern and diversity. Here we introduce a versatile de novo synthesis of...

Two country applications of equilibrium business cycle methodology have succeeded in matching some key features of international fluctuations. However, discrepancies between theory and data remain. This paper identifies a new anomaly related to a basic property of typical models: The prediction of countercyclical net exports is fundamentally related to a (counterfactual) implication for negativ...

We introduce a proper display calculus for (non-distributive) Lattice Logic which is sound, complete, conservative, and enjoys cut-elimination and subformula property. Properness (i.e. closure under uniform substitution of all parametric parts in rules) is the main interest and added value of the present proposal, and allows for the smoothest Belnap-style proof of cut-elimination. Our proposal ...

Polysilanes are known to exhibit the interesting property of σ-bond electron delocalization. By employing optical spectroscopy (UV-vis), it is possible to judge the degree of delocalization and also differentiate parts of the molecules which are conjugated or not. The current study compares oligosilanes of similar chain length but different substitution pattern. The size of the substituents det...
