Timothy A. D. Fowler

Fowler (2008) introduced the bounded-order Lambek Calculus and provided a polynomial time algorithm for its sequent derivability. However, this result is limited because it requires exponential time in the presence of lexical ambiguity. That is, Fowler (2008) did not provide a polynomial time parsing algorithm. The purpose of this paper will be to provide such an algorithm. We will prove an asy...

On the basis of a review of the literature and three new experiments, Fowler (2006) concludes that a contrast account for phonetic context effects is not tenable and is inferior to a gestural account. We believe that this conclusion is premature and that it is based on a restricted set of assumptions about a general perceptual account. Here, we briefly address the criticisms of Fowler (2006), w...

This study documented marked accumulation of cocaine in the human and baboon heart, which was not inhibited by desipramine pretreatment. However, cocaine inhibited 6-[18F]fluoronorepinephrine uptake in heart to the same degree as did desipramine (Fowler et al. 1994). Since uptake of [18F]norepinephrine in the heart is a function of its uptake by the NE transporter (Fowler et al. 1994), its inhi...

A new experimental method of the determination of the evaporating fields F, based on Fowler-Nordheim theory is described. This method fits to any materials both refractory and fusible. Especially this method is effective for the thermo-field microprotrusions. The microprotrusions have usually the radii of curvature r-10-100 A and one or some atoms on the top and well-known methods of Fev determ...

Fowler, Brown and Mann (2000) report a visually-moderated phonetic context effect in which a video disambiguates an acoustically ambiguous precursor syllable which, in turn, influences perception of a following syllable. The present experiments explore this finding and claims that stem from it. Experiment 1 failed to replicate Fowler et al. with novel materials modeled after the original study,...

fullerenes are closed−cage carbon molecules formed by 12 pentagonal and n/2 – 10hexagonal faces, where n is the number of carbon atoms. patrick fowler in his lecture inmcc 2009 asked about the wiener index of fullerenes in general. in this paper werespond partially to this question for an infinite class of fullerenes with exactly 10ncarbon atoms. our method is general and can be applied to full...

This paper reports a a simple dimensionless equation relating to field-emitted vacuum space charge FEVSC in parallel-plane geometry, namely 9 2 2−3 −4 +3=0, where is the FEVSC “strength” and is the reduction in emitter surface field =field-with/field-without FEVSC , and b the formula j=9 2 /4, where j is the ratio of emitted current density JP to that predicted by Child’s law. These equations a...

This paper argues that a tunneling prefactor should appear in expressions for the tunneling probability D relevant to cold field electron emission CFE and in Fowler–Nordheim FN type equations. Except in the case of the “ideally smooth” parabolic barrier, a prefactor is always present for barriers where D can be found by exact solution of the Schrödinger equation. A review of the Jeffreys–Wentze...
