Quadratic Functionals: Positivity, Oscillation, Rayleigh’s Principle
In this paper we give a survey on the theory of quadratic functionals. Particularly the relationships between positive definiteness and the asymptotic behaviour of Riccati matrix differential equations, and between the oscillation properties of linear Hamiltonian systems and Rayleigh’s principle are demonstrated. Moreover, the main tools form control theory (as e.g. characterization of strong o...
متن کاملA Note on Talagrand’s Positivity Principle
Talagrand’s positivity principle, Section 6.6 in [9], states that one can slightly perturb a Hamiltonian in the Sherrington-Kirkpatrick model in such a way that the overlap of two configurations under the perturbed Gibbs’ measure will become typically nonnegative. In this note we observe that abstracting from the setting of the SK model only improves the result and does not require any modifica...
متن کاملThe Coulter Principle for Outlier Detection in Highly Concentrated Solutions
This application note will benefit chemical and material manufacturers concerned about micron and submicron par ticle contamination. Outliers are a common problem in many industrial applications. Outliers can be defined as particles that are significantly larger or smaller than the main particle size distribution, but which occur in a much lower frequency than the main par ticle size. As a simp...
متن کاملUncertainty principle, positivity and L-boundedness for generalized spectrograms
In this paper we are concerned with the properties of positivity, uncertainty principle and continuity in Lp spaces of a generalized spectrogram. In particular we study the connections of a generalized spectrogram, as a subclass of the Cohen class, with the Rihaczek and the Wigner representations. We also consider the behavior of the generalized spectrogram with respect to the positivity and th...
متن کاملKernicterus in Two Generations: A Need for More Aggressive Preventive Measures
Bilirubin induced brain damage is still a common cause of morbidity and mortality in Nigerian infants. No much success has been recorded in decades despite the fact that brain damage from bilirubin toxicity in the newborn is easily preventable with affordable and effective means. We report a case of a newborn with acute bilirubin encephalopathy. This case was considered of interest because the ...
