We hypothesize that the conceptual relation between a verb and its direct object can make a sentence easier ('the cat is eating some food') or harder ('the cat is eating a sock') to parse and understand. If children's limited performance systems contribute to the ungrammatical brevity of their speech, they should perform better on sentences that require fewer processing resources: children shou...

Schrödinger Cat State Atomic Interferometer with Heisenberg-Limited Sensitivity and Detection of Collective States

It is well known that the homotopy category of connected CW-complexes X whose homotopy groups n;(X) are trivial for i> 1 is equivalent to the category of groups. One of the objects of this paper is to prove a similar equivalence for the connected CW-complexes X whose homotopy groups are trivial for i > n + 1 (where n is a fixed non-negative integer). For n = 1 the notion of crossed module inven...

These notes constitute a substantially extended version of a talk given in the Fields Institute (Toronto) during the semester \Singularities and Geometry", that culminated by Arnoldfest in celebration of V. I. Arnold's 60th anniversary. We give a survey of diierentresults showing how an upper bound for the numberof isolated zeros for functions satisfying ordinary diierential equations, may be o...

Interplanetary scintillation (IPS) refers to random fluctuations in radio intensity of distant small-diameter celestial object, over time periods the order 1 s. The scattering and emergent waves are ascribed turbulent density irregularities transported by ubiquitous solar wind streams. spatial correlation length Fresnel radius diffraction two key parameters determining pattern. Such a pattern c...

In this Letter, the main attributes known to affect color quality are treated statistically over a set of 118 spectra representing the current mainstream lighting technology. The color rendering index (CRI) is used to assess color fidelity while colorfulness is used to complement CRI-R(a), supported by the growing evidence that assessment of light spectra cannot overlook color preference inputs...

The issue of context has long troubled the endeavour of modelling and representing knowledge, and today is central to the effective management of digital assets. The deep semantics associated with usage of particular digitised artefacts must be represented to a degree sufficient to avoid intentional or unintentional misrepresentation through the repurposing enabled by digital technologies. Any ...

A common notion of vision, consistent with this excerpt from the first paragraph of David Marr’s seminal book [1], is gained by considering the predicament of a person with a searchlight placed in a pitch-dark room full of unfamiliar furniture. One would hope that, by swinging the beam around, the observer will be able to recognize the objects present in the room (a cat here, an aquarium there,...

We show, for a monoidal closed category V = (V0,⊗, I), that the category V -Cat of small V -categories is locally λ-presentable if V0 is so, and that it is locally λ-bounded if the closed category V is so, meaning that V0 is locally λ-bounded and that a side condition involving the monoidal structure is satisfied. Many important properties of a monoidal category V are inherited by the category ...
