We show that the supersymmetric nonlinear Schrödinger equation is a bi-Hamiltonian integrable system. We obtain the two Hamiltonian structures of the theory from the ones of the supersymmetric two boson hierarchy through a field redefinition. We also show how the two Hamiltonian structures of the supersymmetric KdV equation can be derived from a Hamiltonian reduction of the supersymmetric two b...
The Hamiltonian form of the Hilbert action in the first order tetrad formalism is examined. We perform a non-linear field redefinition of the canonical variables isolating the part of the spin connection which is canonically conjugate to the tetrad. The geometrical meaning of the constraints written in these new variables is examined.
A hypothesis is presented that explains one of the mechanisms by which a heart starts to fail. The hypothesis is that myocardial function of an overloaded or otherwise stressed heart may become impaired by cellular troponin degradation in vital cardiomyocytes. The troponins (I, T and C) regulate actin-myosin interaction, thereby controlling contraction and relaxation. Troponins have been shown ...
The discipline of design by contract encourages to build correct classes wrt a specification right from the beginning. Preand post-conditions, and invariants are used to give semantics to methods, to document a class insofar as they define the contracts that client classes must engage in when they use it and to check classes at runtime in order to test and debug them. The several existing langu...
one of the most important instruments of iranian foreign policy is an active and proactive cultural diplomacy. the exercise of such a diplomacy is more essential in neighboring strategic region of persian gulf. hence, this article strives to explore and explaine different aspects of iran’s cultural diplomacy and various determining variables that necessitate its exercise in that region. the mai...

Cauliflower ear is a serious deformity of the auricle induced by single or repeated injury to the external ear. Few papers deal with surgical techniques for correcting this deformity. We describe the use of ipsilateral excess cartilage to restore the helical rim.
Nowadays atomic optical lattice clocks can perform frequency measurements with a fractional uncertainty at the 10 level in few hours of measurement, outperforming the best caesium (Cs) standards operated in the world. Since the definition of the unit of time is based on Cs, a worldwide debate about the need to promote the redefinition of the second on a optical reference is under-way. At INRIM ...
The diagnosis of thoracic outlet syndrome (TOS) is intrinsically difficult, and the literature about it is full of confusing terminology. Symptoms may arise due to compression of neural and/or vascular elements in one or more of three different locations. A number of tests were developed during the early part of this century, and a variety of syndromes have been described that relate to these t...
