Here it is shown that n points in the plane, no three on a line, always determine at least n slopes, with equality iff the n points are the vertices of an affinely regular polygon. Some bounds are also obtained on the minimum number of ...

In a recent paper [6], van Mill and Mogilski prove that a proper hereditary shape equivalence preserves property C, if its domain is σ-compact. In this note, the same result is established without the hypothesis of σ-compactness. An ...

The first and the third authors obtained a minor-summation formula of Pfaffian, which expresses a weighted sum of minors of any rectangular Nike Air Max Thea White matrix in terms of a single Pfaffian. In this paper, as an application o...

We present new variants of known proofs of cut elimination for intuitionistic and classical sequent calculi. In both cases the proofs proceed by three nested structural inductions, avoiding the explicit use of multi-sets and termination...

An N/D dispersion theory is developed which solves crossing symmetric Low equations. The method is used to generate crossing symmetric Air Max Thea Canada solutions to the Chew-Low model. We show why the technique originally proposed by...

In this paper, we define a new class of multivariate skew-normal distributions. Its properties are studied. In particular we derive its density, moment generating function, the first two moments and marginal and conditional distribution...

Recent studies have shown that the formation of boundaries between the segments – rhombomeres – of the vertebrate hindbrain depends Nike Air Max Classic Trainers on bidirectional signalling between neighbouring cells. This signallin...

It has been known for some time that stimulation of heterotrimeric G protein-coupled receptors can cause cytoskeletal reorganization. A recent report in Developmental Cell (Lowry et al., 2002) demonstrates that the activation of a tyros...

In laser beam recording systems, axial deflection errors of a polygon mirror give rise to banding patterns which recur with each scanner rotation. Experiments for compensating such errors by an additional deflection of the light beam ar...

Using the experimental sessions of Goeree and Holt (2005), we show that step thinking fits the long-run outcome of minimum-effort and median-effort games surprisingly well for all values of the cost parameter. In the latter, the predict...
