A Survey on the Inverse Integrating Factor [PDF]
Qualitative Theory of Dynamical Systems, 2010 The relation between limit cycles of planar differential systems and the inverse integrating factor was first shown in an article of Giacomini, Llibre and Viano appeared in 1996. From that moment on, many research articles are devoted to the study of the properties of the inverse integrating factor and its relation with limit cycles and their ...

Factorization of Behavioral Integrity
2015We develop a bisimulation-based nonintereference property that describes the allowed dependencies between communication behaviors of different integrity levels. The property is able to capture all possible combinations of integrity levels for the “presence” and “content” of actual communications.

Integrating prognostic factors
Breast Cancer Research and Treatment, 1992This special issue of Breast Cancer Research and Treatment addresses the topic of how to evaluate new prognostic factors for breast cancer, and how the information provided by these new factors might be integrated with traditional factors to make better treatment decisions for these patients.

Factors affecting motion integration
Journal of the Optical Society of America A, 2003The perceived direction of motion of a featureless contour inside a circular aperture is always perpendicular to the contour's orientation, regardless of its true motion (the aperture problem). This study investigates the circumstances under which unambiguous feature motion (of line terminators, single dots, or truncations of a D6 pattern) in adjacent ...

Journal of Lie Theory, 2003
The authors consider the differential equation \(\dot{x}=f(x)\) in \(\mathbb{C}^2\), where \(f\) is an analytic or formal vector field and continues his investigations on the existence of local integrating factors near a stationary point. Two classes of degenerate stationary points are considered. The first one has a nilpotent linear part. It is proved

Factoring Ideals in Integral Domains
2013A classical generalization of the Fundamental Theorem of Arithmetic states that an integral domain is a principal ideal domain if and only if each of its proper ideals can be factored as a finite product of principal prime ideals. If the “principal” restriction is removed, one has a characterization of (nontrivial) Dedekind domains. The purpose of this

Integral of the boltzmann factor
Journal of Thermal Analysis, 1996A new approximation is proposed to the integral of the Boltzmann factor: $$\int\limits_0^T {e^{ - E/RT} dT} $$ and is shown to be more accurate than the existing approximations over the entire range of values ofE/RT, including low values.

Integration as a Factor in Psycholinguistic Performance
Perceptual and Motor Skills, 1968From fish to man, the nervous system has progressed toward improved interaction among formerly independent sensory modalities (2, 4 ) . Kephart ( 3 ) indicated that perceptual and motor functions in children may develop somewhat independently of one another.

On Integrating Factors and a Perturbation Method
Volume 3A: 15th Biennial Conference on Mechanical Vibration and Noise — Vibration of Nonlinear, Random, and Time-Varying Systems, 1995Abstract In this paper the fundamental concept (due to Euler, 1734) of how to make a first order ordinary differential equation exact by means of integrating factors, is extended to n-th order (n ≥ 2) ordinary differential equations and to systems of first order ordinary differential equations.
