The reaction of a saddle-distorted Mo(v)-dodecaphenylporphyrin complex and a Keggin-type polyoxometalate gives a discrete and nanosized molecule, [{Mo(DPP)(O)}(2)(H(2)SiW(12)O(40))], which involves direct coordination between the Mo(v) centers and terminal oxo groups of the polyoxometalate and exhibits excellent stability in solution to show reversible multi-redox processes.

In this report we study the stability of a nonsymmetric saddle-point problem. It is discretized with equal order finite elements and stabilized with a consistent regularization. In this way we achieve a stable finite element discretization of optimal order approximation properties.

We show that the correct entropy, temperature (and absorption probability) of non-extremal black p-brane can be reproduced by a certain thermodynamical model when maximizing its entropy. We argue the relation of the model and the geometrical similarity of black p-brane and R AdS black hole at near horizon region. We also argue the relation of the maximization of the entropy and a saddle point a...

We discuss the final stages of double ionization of atoms in a strong linearly polarized laser field within a classical model. We propose that all trajectories leading to non-sequential double ionization pass close to a saddle in phase space which we identify and characterize. The saddle lies in a two degree of freedom subspace of symmetrically escaping electrons. The distribution of longitudin...

Abstract. The properties of the mean first passage time in a system characterized by multiple periodic attractors are studied. Using a transformation from a high dimensional space to 1D, the problem is reduced to a stochastic process along the path from the fixed point attractor to a saddle point located between two neighboring attractors. It is found that the time to switch between attractors ...

We study the existence and stability of periodic solutions of a canonical mass-spring model of electrostatically actuated micro-electro-mechanical system (MEMS) by means of classical topological techniques like a-priori bounds, Leray-Schauder degree and topological index. A saddle-node bifurcation is revealed, in analogy with the autonomous case.

The large body of experimental data on nuclear fission is analyzed with a semiempirical ordering scheme based on the macro-microscopic approach and the separability of compound-nucleus and fragment properties on the fission path. We apply the statistical model to the non-equilibrium descent from saddle to scission, taking the influence of dynamics into account by an early freeze out. The presen...

As a first step to derive the IBM from a microscopic nuclear hamil-tonian, we bosonize the pairing hamiltonian in the framework of the path integral formalism respecting both the particle number conservation and the Pauli principle. Special attention is payed to the role of the Goldstone bosons. We construct the saddle point expansion which reproduces the sector of the spectrum associated to th...
