OBJECTIVE To analyse the effects of gait therapy for patients after acute stroke in a randomized controlled trial. METHODS Fifty-six patients with a mean of 8 days post-stroke participated in: (i) gait trainer exercise; (ii) walking training over ground; or (iii) conventional treatment. Patients in the gait trainer exercise and walking groups practiced gait for 15 sessions over 3 weeks and re...

There are two basic pieces of ground clearing needed before we get specific. First, marginalization is a relational statement. A category X cannot be marginalized in and of itself. It always has to be marginalized in relation to some other category, Y. So conceptualization requires an explicit statement of both X and Y—although in many cases Y is thought of implicitly as “the rest of society”, ...

in this article, we have shown, for the add-point monad t, thepartial morphism category set*is isomorphic to the kleisli category sett. alsowe have proved that the category, sett, of t-algebras is isomorphic to thecategory set of pointed sets. finally we have established commutative squaresinvolving these categories.

Extended cubical sets (with connections and interchanges) are presheaves on a ground category, the extended cubical site K, corresponding to the (augmented) simplicial site, the category of finite ordinals. We prove here that K has characterisations similar to the classical ones for the simplicial analogue, by generators and relations, or by the existence of a universal symmetric cubical monoid...

An existing procedure to compute left Kan extensions over the ground category Set also computes left Kan extensions over the ground categories Cat, 2-Cat, n-Cat for any n and indeed !-Cat. Therefore extension data struc-tured in this manner already can make use of the left Kan extension notion of a best possible approximation. Examples include systems of labeled transition systems and certain h...

In the theory of operads we consider generalized symmetric power functors defined by sums of coinvariant modules. One observes classically that the symmetric functor construction provides an isomorphism from the category of symmetric modules to a split subcategory of the category of functors on dgmodules (if dg-modules form our ground category). The purpose of this article is to obtain a simila...

In computed tomographic lung cancer screening, both solid and ground glass nodules are regularly encountered. Ground glass nodules may or may not have a solid component and it has been shown that they have a much higher chance of being malignant in comparison to solid nodules. Computer-aided detection (CAD) systems designed for solid nodules perform poorly on detection of ground glass nodules, ...

In this chapter, we aim to connect the areas of object categorization and figure-ground segmentation. We present a novel method for the categorization of unfamiliar objects in difficult real-world scenes. The method generates object hypotheses without prior segmentation, which in turn can be used to obtain a category-specific figure-ground segmentation. In particular, the proposed approach uses...
