Limit theorems for nondegenerate U-statistics of continuous semimartingales

open access: yes, 2014
This paper presents the asymptotic theory for nondegenerate $U$-statistics of high frequency observations of continuous It\^{o} semimartingales. We prove uniform convergence in probability and show a functional stable central limit theorem for the ...

Estimation of Distribution Overlap of Urn Models [PDF]

open access: yes, 2012
A classical problem in statistics is estimating the expected coverage of a sample, which has had applications in gene expression, microbial ecology, optimization, and even numismatics.

The thioredoxin‐like and one glutaredoxin domain are required to rescue the iron‐starvation phenotype of HeLa GLRX3 knock out cells

open access: yesFEBS Letters, EarlyView.
Glutaredoxin (Grx) 3 proteins contain a thioredoxin domain and one to three class II Grx domains. These proteins play a crucial role in iron homeostasis in eukaryotic cells. In human Grx3, at least one of the two Grx domains, together with the thioredoxin domain, is essential for its function in iron metabolism.

Resampling methods for estimating functions with U-statistic structure [PDF]

open access: yes, 2004
Suppose that inference about parameters of interest is to be based on an unbiased estimating function that is U-statistic of degree 1 or 2. We define suitable studentized versions of such estimating functions and consider asymptotic approximations as ...

Asymptotics for the Moment Convergence of U-Statistics in LIL

open access: yesJournal of Inequalities and Applications, 2010
Let Un be a U-statistic based on a symmetric kernel h(x,y) and i.i.d. samples {X,Xn;n≥1}. In this paper, the exact moment convergence rates in the law of the iterated logarithm and the law of the logarithm of Un are obtained, which extend previous

Indicators of Simulated Driving Skills in Adolescents with Autism Spectrum Disorder

open access: yesOpen Journal of Occupational Therapy, 2013
Adolescents are at high risk for motor vehicle crashes (MVCs). Teens with autism spectrum disorder (ASD) may have an even greater risk for MVCs due to impaired visual, cognitive, and motor skills critical for driving.

Large deviations for U-statistics

open access: yesJournal of Multivariate Analysis, 1992
AbstractA large deviation principle for U-statistics is presented. It relies on the large deviation for B-valued r.v. and on the spectral decomposition of the kernel of the U-statistic.

P‐glycoprotein modulates the fluidity gradient of the plasma membrane of multidrug resistant CHO cells

open access: yesFEBS Letters, EarlyView.
To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

Asymptotic distributions for a class of generalized $L$-statistics

open access: yes, 2010
We adapt the techniques in Stigler [Ann. Statist. 1 (1973) 472--477] to obtain a new, general asymptotic result for trimmed $U$-statistics via the generalized $L$-statistic representation introduced by Serfling [Ann. Statist. 12 (1984) 76--86].

Turbulent characteristics of saltation and uncertainty of saltation model parameters [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
It is widely recognised that saltation is a turbulent process, similar to other transport processes in the atmospheric boundary layer. Due to a lack of high-frequency observations, the statistic behaviour of saltation is so far not well understood. In
