Noxious skin stimuli which are sufficiently intense to produce tissue injury, characteristically generate prolonged poststimulus sensory disturbances that include continuing pain, an increased sensitivity to noxious stimuli and pain following innocuous stimuli. This could result from either a reduction in the thresholds of skin nociceptors (sensitization) or an increase in the excitability of t...

We describe an p-mechanical (see funct-an/9405002 and quantph/9610016) brackets which generate quantum (commutator) and classic (Poisson) brackets in corresponding representations of the Heisenberg group. We do not use any kind of semiclassic approximation or limiting procedures for ~ → 0.

We consider the boundary value problem:    x(t) = f(t, x(t)), a ≤ t ≤ b, m > 1 x(a) = β0 ∆x ≡ x(b)− x(a) = βk+1, k = 0, ..., m− 2 where x(t) = (x(t), x ′ (t), ...., x(m−1)(t)), βi ∈ R, i = 0, ..., m − 1, and f is continuous at least in the interior of the domain of interest. We prove the existence and uniqueness of the solution under certain conditions.

In these lectures we discuss some basic aspects of Hamiltonian formalism, which usually do not appear in standard texbooks on classical mechanics for physicists. We pay special attention to the procedure of Hamiltonian reduction illustrating it by the examples related to Hopf maps. Then we briefly discuss the supergeneralisation(s) of the Hamiltonian formalism and present some simple models of ...

Two linear algebra based strategies are presented to deal with general classical mechanics problems with constraints. Classical concepts such as holonomic and nonholonomic constraints, virtual displacements, principle of virtual work, Hamilton’s principle and method of Lagrange multipliers are critiqued.

If the classical inference relation is considered, AC is clearly not deductively valid. Moreover, adding AC to Classical Logic (CL) as an extra inference rule would result in the trivial logic. This is called the /irrelevance problem/ towards abduction. In order to provide a nice formal account of abduction processes, this problem has to be faced. In this lunch talk, I will present several adap...

The FP7 PHENICX project focuses on creating a new digital classical concert experience, improving the accessibility of classical music concert performances by enhancing and enriching them in novel digital ways, In this paper, we present the project’s foreseen use cases. Subsequently, we summarize initial use case feedback from two different user groups. Despite the early stage of the project, t...

This document reports experiment and result of Fudan WIM group in Expert Search track in TREC 2006. Our research mainly focus on the measurement of expertise. Inspired by the human procedure of expert search, we construct 2 models, a language model and a social network model are compared. The association function of expert and document is modified. And email search techniques are employed in do...
