A synergetic control technique for stabilizing a priori unknown saddle steady states of dynamical systems is described. The method involves an unstable filter technique combined with a derivative feedback. The cut-off frequency of the filter is not limited by the damping of the system, and therefore can be set relatively high.

The problem of determining which activated (and slow) transitions can occur from a given initial state at a finite temperature is addressed. In the harmonic approximation to transition state theory this problem reduces to finding the set of low lying ...

ON OCCASION it is important to avoid irritation of the skin under spectacle nose pads. Epitheliomas and keratoses particularly arise in this area on the lateral upper nose. Following surgical or radiation treatment it is especially necessary to avoid pressure to promote healing.

Local Saddle Point Optimization: A Curvature Exploitation Approach
International Conference on Artificial Intelligence and Statistics, 2018Gradient-based optimization methods are the most popular choice for finding local optima for classical minimization and saddle point problems. Here, we highlight a systemic issue of gradient dynamics that arise for saddle point problems, namely the ...

High-Index Optimization-Based Shrinking Dimer Method for Finding High-Index Saddle Points
SIAM Journal on Scientific Computing, 2019We present a high-index optimization-based shrinking dimer (HiOSD) method to compute index-$k$ saddle points as a generalization of the optimization-based shrinking dimer method for index-1 saddle ...

Hyperasymptotics for integrals with saddles
Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1991Integrals involving exp { – k f ( z )}, where | k | is a large parameter and the contour passes through a saddle of f ( z ), are approximated by refining the method of steepest descent to include exponentially

A Dipleiadiene-Embedded Aromatic Saddle Consisting of 86 Carbon Atoms.
Angewandte Chemie, 2018This study presents a new type of negatively curved nanographene (C86 H32 ) that contains an unprecedented pattern of heptagons. A tert-butylated derivative of C86 H32 was successfully synthesized using tetrabenzodipleiadiene as a key building block ...

The deformities known as saddle nose and boxer's nose result from injuries or poorly planned nasal surgery. Boxer's nose may eventually be corrected using Straith's method. It is possible to correct both deformities by simply using a bone graft. Neither the use of cartilage grafts nor organic or inorganic inclusions are recommended, the former because ...

EMBOLIZATION to the aortic bifurcation accounts for 10% to 25% of all arterial emboli and has been associated with an operative mortality which approaches 75% and a limb salvage of approximately 15%. 1-3 Only 27 successful aortic bifurcation embolectomies had been reported prior to 1951.

Examining the fit of the saddle is perhaps the most important aspect of examining a horse with a suspected back problem. If the back problem is corrected and a poorly fitting saddle is placed on the back, the problems will return. An ill-fitting saddle contributes to direct and compensatory lower leg lameness making it even more imperative to correct ...
