LowResolution Phases: Influence on SIR Syntheses and Retrieval with DoubleStep Filtration
 Acta Cryst
, 1991
"... Different sources of error in single isomorphous replacement (SIR) maps are analysed. It is shown that SIR maps are good enough in themselves to localize a molecule but the absence of lowresolution reflections can distort he image of the molecule. Even in this case the molecule can be reliably loca ..."

localized using the doublestep filtration technique of Urzhumtsev, Lunin & Luzyanina [Acta Cryst. (1989), A45, 3439] if parameters are chosen appropriately. On the other hand, such syntheses may be considerably improved by addition of lowresolution structure factors. A very simple procedure
Learning lowlevel vision
 International Journal of Computer Vision
, 2000
"... We show a learningbased method for lowlevel vision problems. We setup a Markov network of patches of the image and the underlying scene. A factorization approximation allows us to easily learn the parameters of the Markov network from synthetic examples of image/scene pairs, and to e ciently prop ..."

propagate image information. Monte Carlo simulations justify this approximation. We apply this to the \superresolution " problem (estimating high frequency details from a lowresolution image), showing good results. For the motion estimation problem, we show resolution of the aperture problem
Specification Analysis of Affine Term Structure Models
 JOURNAL OF FINANCE
, 2000
"... This paper explores the structural differences and relative goodnessoffits of affine term structure models (ATSMs55). Within the family of ATSMs there is a tradeoff between flexibility in modeling the conditional correlations and volatilities of the risk factors. This tradeoff is formalized by ou ..."

Factoring wavelet transforms into lifting steps
 J. FOURIER ANAL. APPL
, 1998
"... This paper is essentially tutorial in nature. We show how any discrete wavelet transform or two band subband filtering with finite filters can be decomposed into a finite sequence of simple filtering steps, which we call lifting steps but that are also known as ladder structures. This decompositio ..."

A yieldfactor model of interest rates
 Math. Finance
, 1996
"... This paper presents a consistent and arbitragefree multifactor model of the term structure of interest rates in which yields at selected fixed maturities follow a parametric multivariate Markov diffusion process with “stochastic volatility. ” The yield of any zerocoupon bond is taken to be a matur ..."

of the factors traditionally mentioned as influencing the term structure are thus included in a way which is fully consistent with maximizing behavior and rational expectations. The model leads to specific formulas for bond prices which are well suited for empirical testing.
Changes in relative wages, 19631987—Supply and demand factors
 Quarterly Journal of Economics
, 1992
"... A simple supply and demand framework is used to analyze changes in the U. S. wage structure from 1963 to 1987. Rapid secular growth in the demand for moreeducated workers, "moreskilled " workers, and females appears to be the driving force behind observed changes in the wage structure. M ..."

Theory of the Firm: Managerial Behavior, Agency Costs and Ownership Structure
, 1976
"... This paper integrates elements from the theory of agency, the theory of property rights and the theory of finance to develop a theory of the ownership structure of the firm. We define the concept of agency costs, show its relationship to the ‘separation and control’ issue, investigate the nature of ..."

Fit indices in covariance structure modeling: Sensitivity to underparameterized model misspecification
 Psychological Methods
, 1998
"... This study evaluated the sensitivity of maximum likelihood (ML), generalized least squares (GLS), and asymptotic distributionfree (ADF)based fit indices to model misspecification, under conditions that varied sample size and distribution. The effect of violating assumptions of asymptotic robustn ..."
