Uniform asymptotics for robust location estimates when the scale is unknown
, 2004 Most asymptotic results for robust estimates rely on regularity conditions that are difficult to verify in practice. Moreover, these results apply to fixed distribution functions.

S‐asymptotic expansion of distributions [PDF]
International Journal of Mathematics and Mathematical Sciences, 1987 This paper contains first a definition of the asymptotic expansion at infinity of distributions belonging to , named S‐asymptotic expansion, as also its properties and application to partial differential equations.

A Soft Microrobot for Single‐Cell Transport, Spheroid Assembly, and Dual‐Mode Drug Screening
Advanced Materials, EarlyView.A soft, untethered hydrogel microrobot enables precise single‐cell delivery, self‐assembly into 3D spheroids, and real‐time thermal actuation. Driven by light‐induced convection and embedded with gold nanorods and temperature sensors, the microrobot guides cells, modulates local microenvironments, and supports drug testing.

Testing Non-Linear Ordinal Responses in L2 × K Tables
Ruhuna Journal of Science, 2007 In comparative studies responses of two populations are often summarized in stratified 2 × K tables with ordinal categories. A test, called QEt test, is proposed for testing the homogeneity of the populations against non-linear alternatives in such ...

Extremal properties of the beta-normal distribution
Journal of Inequalities and Applications, 2022 Asymptotic behaviors of the extremes of the beta-normal distribution are derived. The higher-order asymptotic expansions of the probability density and cumulative distribution functions for the maximum are given under an optimal normalizing constants. In

, 2016 We investigate front propagation in systems with diffusive and sub-diffusive behavior. The scaling behavior of moments of the diffusive problem, both in the standard and in the anomalous cases, is not enough to determine the features of the reactive ...

Asymptotic failure distributions
Stochastic Processes and their Applications, 1981 AbstractWe consider a single device shock model in which the shocks arrive as a renewal process. We study the asymptotic shape of the failure distribution and find conditions on the renewal process and the ability of the device to survive shocks so that the failure distribution is asymptotically Increasing Failure Rate.

Advanced Materials, EarlyView.Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

On Diagnostic Checking of Vector ARMA-GARCH Models with Gaussian and Student-t Innovations
Econometrics, 2013 This paper focuses on the diagnostic checking of vector ARMA (VARMA) models with multivariate GARCH errors. For a fitted VARMA-GARCH model with Gaussian or Student-t innovations, we derive the asymptotic distributions of autocorrelation matrices of the ...

Spectral Tuning of Hyperbolic Shear Polaritons in Monoclinic Gallium Oxide via Isotopic Substitution
Advanced Materials, EarlyView.Spectral tuning of highly directional hyperbolic shear polaritons is realized via isotopic substitution of 16O to 18O in monoclinic β$\beta$‐phase gallium oxide. A red‐shift of almost 40 cm−1 is experimentally demonstrated with near‐field imaging, corroborated by the permittivity change extracted from far‐field experiments and density functional theory.
