The Effect of UV Irradiation on the Z-Tetraol Boundary Lubricant
Tribology Online, 2012 The UV irradiation of Z-Tetraol films on amorphous nitrogenated carbon surfaces was investigated. COF2 evolution, captured in the gas phase, decreased with increasing number of OH end groups in the order: Z > Zdol > Z-Tetraol after UV irradiation ...

On the asymptotic properties of the group lasso estimator for linear models
Electronic Journal of Statistics, 2008 We establish estimation and model selection consistency, prediction and estimation bounds and persistence for the group-lasso estimator and model selector proposed by Yuan and Lin (2006) for least squares problems when the covariates have a natural grouping structure.

Statistical degradation modelling of Poly(D,L-lactide-co-glycolide) copolymers for bioscaffold applications. [PDF]
PLoS ONE, 2018 This methodology permits to simulate the performance of different Poly(D,L-lactide-co-glycolide) copolymer formulations (PDLGA) in the human body, to identify the more influencing variables on hydrolytic degradation and, thus, to estimate biopolymer ...

On asymptotic densities and generic properties in finitely generated groups
Groups – Complexity – Cryptology, 2010 Let \(\mathcal P\) be a group property. Then the `asymptotic density' (which is a method to compute densities and/or probabilities within infinite finitely generated groups) determines the measure of the set of elements that satisfy the property \(\mathcal P\).

Asymptotic properties of the quantum representations of the modular group [PDF]
Transactions of the American Mathematical Society, 2012 We study the asymptotic behaviour of the quantum representations of the modular group in the large level limit. We prove that each element of the modular group acts as a Fourier integral operator. This provides a link between the classical and quantum Chern-Simons theories for the torus.

Semiparametric estimation of shifts on compact Lie groups for image registration [PDF]
, 2008 In this paper we focus on estimating the deformations that may exist between similar images in the presence of additive noise when a reference template is unknown. The deformations aremodeled as parameters lying in a finite dimensional compact Lie group.

Asymptotic properties of a goodness-of-fit test based on maximum correlations [PDF]
, 2008 We study the efficiency properties of the goodness-of-fit test based on the Qn statistic introduced in Fortiana and Grané (2003) using the concepts of Bahadur asymptotic relative efficiency and Bahadur asymptotic optimality.

Algorithmic and asymptotic properties of groups [PDF]
, 2007 This is a survey of the recent work in algorithmic and asymptotic properties of groups. I discuss Dehn functions of groups, complexity of the word problem, Higman embeddings, and constructions of finitely presented groups with extreme properties (monsters).

Animals, 2020 Inclusion of fiber in gestation diets is a method for enhancing satiety and reducing abnormal behaviors in restricted feeding sows without providing excess energy. The purpose of this study was to use an in vitro-in vivo method to appraise the effects of

The log-linear group-lasso estimator and its asymptotic properties
Bernoulli, 2012 We define the group lasso estimator for the natural parameters of the exponential families of distributions representing hierarchical log-linear models under multinomial sampling scheme. Such estimator arises as the unique solution of a convex penalized likelihood program using the group lasso penalty.
