In this paper we consider the problem of estimating a coefficient of a strongly elliptic partial differential operator in stochastic parabolic equations. The coefficient is a bounded function of time. We compute the maximum likelihood estimate of the function on an approximating space (sieve) using a finite number of the spatial Fourier coefficients of the solution and establish conditions that...

Recently a non-perturbative formula for the RG flow between UV and IR fixed points of the coefficient in the trace of the energy momentum tensor of the Euler density has been obtained for N = 1 SUSY gauge theories by relating the trace and R-current anomalies. This result is compared here with an earlier perturbation theory analysis based on a naturally defined metric on the space of couplings ...

Negative symptoms prevalent in schizophrenia are associated with poor outcome. Developing new instruments to identify new treatments was highlighted at the NIMH-MATRICS Consensus Development Conference on Negative Symptoms. The new Brief Negative Symptoms scale (BNSS) demonstrated strong psychometric properties, but there is a need for validating it in non-English languages. A multi-center stud...

Because of the sensor or environment problem, the multi-sensor detection data can result in data mutation for the individual sensor. To obtain consistent, stable and accurate tested target description, the paper adopts confidence distance matrix, distance correlation coefficient and p-value significant test to get The number of optimal fusion number of multi-sensor, and uses maximum likelihood ...

Cronbach's a is the most widely used index of the reliability of a scale. However, its use and interpretation can be subject to a number of errors. This article discusses the historical development of a from other indexes of internal consistency (split-half reliability and Kuder-Richardson 20) and discusses four myths associated with a: (a) that it is a fixed property of the scale, (b) that it ...

background: we aimed to develop and validate the persian version of short form mcgill pain questionnaire-2 (sf-mpq-2) in patients with knee osteoarthritis. methods: translation and back translation was performed using beaton’s guideline. after a consensus has achieved on the persian version of sf-mpq-2, it was administered to 30 patients with knee osteoarthritis in a pilot study. then, we enrol...

OBJECTIVE To validate the psychometric properties of the questionnaire on hand function assessment in leprosy. METHODS Study conducted with a convenience sample of 101 consecutive patients in Brasília (Central-Western Brazil), from June 2008 to July 2009. The individuals were adults affected by leprosy, with impairment of the ulnar, median and radial nerves. Interobservers and intraobserver r...

Results: Using ASQ 18% of children were detected as having developmental disorders. Developmental screening with PDQ showed that developmental delay or doubtful condition was seen in 20% and 19% of children respectively. The estimated consistency coefficient between PDQ II and ASQ for fine and gross motor domains was 0.05 and 0.24, and for language and personal-social issues were 0.18 and 0.06,...

We discuss nonparametric estimation of the distribution function G(x) of the autoregressive coefficient from a panel of N random-coefficient AR(1) data, each of length n, by the empirical distribution of lag 1 sample correlations of individual AR(1) processes. Consistency and asymptotic normality of the empirical distribution function and a class of kernel density estimators is established unde...
