Spectral Measures
"... The theory of spectra for Banach algebras is outlined, including the GelfandNaǐmark theorem for commutative B ∗algebras. Resolutions of the identity are introduced, with examples; finally, we prove the spectral theorem for bounded normal operators on a Hilbert space, and conclude with some applica ..."

Some properties of spectral measures
 Appl. Comput. Harmon. Anal
, 2006
"... Abstract. A Borel measure µ in R d is called a spectral measure if there exists a set Λ ⊂ R d such that the set of exponentials {exp(2πiλ · x) : λ ∈ Λ} forms an orthogonal basis for L 2 (µ). In this paper we prove some properties of spectral measures. In particular, we prove results that highlight t ..."

ON THE GROWTH OF THE SPECTRAL MEASURE
, 1997
"... ABSTRACT. We are concerned with the asymptotics of the spectral measure associated with a selfadjoint operator. By using comparison techniques we shall show that the eigenfunctionals of L2 are close to the eigenfunctionals L1 if and only if dr1 dF2 as A oo. ..."

An approach to correlate tandem mass spectral data of peptides with amino acid sequences in a protein database
 J. Am. Soc. Mass Spectrom
, 1994
"... A method to correlate the uninterpreted tandem mass spectra of peptides produced under low energy (lo50 eV) collision conditions with amino acid sequences in the Genpept database has been developed. In this method the protein database is searched to identify linear amino acid sequences within a mas ..."

mass tolerance of * 1 u of the precursor ion molecular weight. A crosscorrelation function is then used to provide a measurement of similarity between the masstocharge ratios for the fragment ions predicted from amino acid sequences obtained from the database and the fragment ions observed
Portfolio Optimization with Spectral Measures of Risk
, 2008
"... We study Spectral Measures of Risk from the perspective of portfolio optimization. We derive exact results which extend to general Spectral Measures Mφ the Pflug–Rockafellar–Uryasev methodology for the minimization of α–Expected Shortfall. The minimization problem of a spectral measure is shown to b ..."

Finding community structure in networks using the eigenvectors of matrices
, 2006
"... We consider the problem of detecting communities or modules in networks, groups of vertices with a higherthanaverage density of edges connecting them. Previous work indicates that a robust approach to this problem is the maximization of the benefit function known as “modularity ” over possible div ..."

Concentration of the Spectral Measure for Large Matrices
 ELECTRONIC COMMUNICATIONS IN PROBABILITY
, 2000
"... We derive concentration inequalities for functions of the empirical measure of eigenvalues for large, random, self adjoint matrices, with not necessarily Gaussian entries. The results presented apply in particular to nonGaussian Wigner and Wishart matrices. We also provide concentration bounds fo ..."
