This paper collects together a miscellany of results originally motivated by the analysis of the generalization performance of the “maximum-margin” algorithm due to Vapnik and others. The key feature of the paper is its operator-theoretic viewpoint. New bounds on covering numbers for classes related to Maximum Margin classes are derived directly without making use of a combinatorial dimension s...

In this paper we present Jam, an extension of the Java language supporting mixins, that is, parametric heir classes. A mixin declaration in Jam is similar to a Java heir class declaration, except that it does not extend a fixed parent class, but simply specifies the set of fields and methods a generic parent should provide. In this way, the same mixin can be instantiated on many parent classes,...

Farach, Kannan and Warnow (1995) have defined Problem MCA (matrix completion to additive) and proved it to be NP-complete: given a partial dissimilarity d on a finite set X , does there exist a tree metric extending d to all pairs of elements of X . We use a previously described simple method of phylogenetic reconstruction, and its extension to partial dissimilarities, to characterize some clas...

In this paper we describe a new approach to programming which generalizes object-oriented programming. It is based on using a new programming construct, called concept, which generalizes classes. Concept is defined as a pair of two classes: one reference class and one object class. Each concept has a parent concept which is specified using inclusion relation generalizing inheritance. We describ...

In this column, the author outlines some of the results of the Listening to Mothers Survey, conducted by the Maternity Center Association, and the implications of the results on childbirth education.

We consider three new classes of meromorphic functions defined by an extension the Wanas operator and two integral operators, in order to study some preservation properties classes. The purpose paper is find conditions such that, when we apply Jp,γ function from ΣSp,qn(α,δ), respectively ΣSp,qn(α), obtain also a same class. define on class functions, denoted Jp,γ,h, where h normalized analytic ...

In April 2010 the International Finance Corporation announced the creation of the African, Latin American, and Caribbean fund, a new co-investment vehicle funded largely with commitments from sovereign wealth and pension funds. The fund’s objective was to draw on the IFC and the World Bank’s strengths in emerging markets to identify and support enterprises that might not otherwise have come to ...

For a bar and joint framework (G, p) with point group C3 which describes 3-fold rotational symmetry in the plane, it was recently shown in (Schulze, Discret. Comp. Geom. 44:946-972) that the standard Laman conditions, together with the condition derived in (Connelly et al., Int. J. Solids Struct. 46:762-773) that no vertices are fixed by the automorphism corresponding to the 3-fold rotation (ge...
