Strong Approximations for Nonlinear Transformations of Integrated Time Series [PDF]

In this paper we establish the strong approximations for the nonlinear transformations of integrated time series. Both the asymptotically homogeneous and integrable transformations are considered, and the explicit rates for the convergence to their limit

Subsampling inference in cube root asymptotics with an application to Manski's maximum score estimator [PDF]

, 2000
Kim and Pollard (Annals of Statistics, 18 (1990) 191?219) showed that a general class of M-estimators converge at rate n1/3 rather than at the standard rate n1/2. Many times, this situation arises when the objective function is non-smooth.

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

Advanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Plancherel-Rotach Asymptotics for q-Orthogonal Polynomials

, 2013
We establish the Plancherel-Rotach-type asymptotics around the largest zero (the soft edge asymptotics) for some classes of polynomials satisfying three-term recurrence relations with exponentially increasing coefficients.

Implementation of the Kachanov — Rabotnov creep model with damage in ABAQUS UMAT: analysis of stress and damage fields at the crack tip

Вестник Самарского университета: Естественнонаучная серия
This study focuses on a finite element analysis of stress, strain, and damage fields near the tip of a central crack in a plate subjected to a tensile load under creep conditions, taking into account the damage accumulation effect.

Asymptotics of the Solution of the Bisingular Problem for a System of Linear Parabolic Equations. II

Моделирование и анализ информационных систем, 2013
Suppose we are given a bisingular initial boundary-value problem for a system of parabolic equations that contains a small parameter ε² at the second derivative and √ ε at the first derivative with respect to the spatial variable. We prove an asymptotics

Quicksort asymptotics

Journal of Algorithms, 2002
The number of comparisons X_n used by Quicksort to sort an array of n distinct numbers has mean mu_n of order n log n and standard deviation of order n. Using different methods, Regnier and Roesler each showed that the normalized variate Y_n := (X_n - mu_n) / n converges in distribution, say to Y; the distribution of Y can be characterized as the ...

Impedance of Nonelectroneutral Solid Electrolyte Interphases With Nanopores: A Theoretical Model

Advanced Science, EarlyView.
Physical modeling reveals that often‐neglected non‐electroneutrality and nanopores in the solid‐electrolyte interphase (SEI) govern the impedance behavior. Under nonreactive conditions, the low‐frequency constant‐phase element (CPE) phenomenon can be attributed to the nonelectroneutral local conditions in the SEI.

Joint ruin probability and risk contagion measure in a quota-share reinsurance risk model

Nonlinear Analysis
Consider a quota-share reinsurance risk model with constant premiums and stochastic returns in which an insurer purchases fixed-proportion quota-share reinsurance for its business line. Both the insurer and reinsurer may engage in risk-free investments,

Low‐Power Control Of Resistance Switching Transitions in First‐Order Memristors

Advanced Electronic Materials, EarlyView.
Joule losses are a serious concern in modern integrated circuit design. In this regard, minimizing the energy necessary for programming memristors should be handled with care. This manuscript presents an optimal control framework, allowing to derive energy‐efficient programming voltage protocols for resistance switching devices. Following this approach,
