In this article I explore the relationship between laugh responses and the turns which they orient to. I consider whether it is possible to identify properties of the prior turns that the recipient may be orienting to in laughing. Thus, I begin by briefly exploring the relationship between laughter and humour in interaction. But I point to some of the difficulties in identifying what it is that...

We performed a quasiclassical trajectory dynamics study on a model analytical 21-dimensional (7 active atoms) potential energy surface (PES) to examine in detail the mechanism of the hydrogen absorption in a simple (NaAlH(4))(2)Ti model system. The reaction involves a capture of H(2) by the Ti centre and formation of the (η(2)-H(2))Ti(NaAlH(3))(2) coordination complex containing the side-on bon...

We consider the Gierer-Meinhardt system with small inhibitor diffusivity and very small activator diffusivity in a bounded and smooth two-dimensional domain. For any given positive integer k we construct a spike cluster consisting of k boundary spikes which all approach the same nondegenerate local maximum point of the boundary curvature. We show that this spike cluster is linearly stable. The ...

The Dirac equation in (1+1) dimensions with a non-local PT symmetric potential of separable type is studied by means of the Green function method: properties of bound and scattering states are derived in full detail and numerical results are shown for a potential kernel of Yamaguchi type, inspired by the treatment of low-energy nucleonnucleon interaction. PACS:03.65.CGe, 03.65.Nk, 03.65.Pm, 11....

Recently, bag of spatio-temporal local features based methods have received significant attention in human action recognition. However, it remains a big challenge to overcome intra-class variations in cases of viewpoint, geometric and illumination variance. In this paper we present Bag of Spatiotemporal Synonym Sets (ST-SynSets) to represent human actions, which can partially bridge the semanti...

The Residual Potential Method, introduced by Geers [ l ] , appears to be a very promising technique in the solution of sol id-f luid interaction problems. The theoretical development of the method in cylindrical coordinates was presented in [1,2]. In [3], Geers presents some numerical results obtained using the Residual Potential Method in spherical coordinates; however, the theoretical treatme...

An assessment is made of the dominant features contributing to the triton potential energy, with the objective of understanding qualitatively their origins and sensitivities. Relativistic effects, short-range repulsion, and OPEP dominance are discussed. A determination of the importance of various regions of nucleon-nucleon separation is made numerically.

We present an analytical investigation of revival phenomena in the finite square-well potential. The classical motion, revival, and super-revival time scales are derived exactly for wave packets excited in the finite well. These time scales exhibit a richer dependence on wave-packet energy and on potential-well depth than has been found in other quantum systems: They explain, for example, the d...

Kramers’ exit problem is concerned with noise activated escape from a potential well. In case the noise strength, , (temperature measured in units of potential barrier height) is small this becomes a singular perturbation problem. It is shown that actually, most of the probability of the exit points on the separatrix is located at a distance O( √ ) from the saddle point and the probability vani...
