Dynamics of Dollard asymptotic variables. Asymptotic fields in Coulomb scattering [PDF]

, 2016
Generalizing Dollard's strategy, we investigate the structure of the scattering theory associated to any large time reference dynamics $U_D(t)$ allowing for the existence of M{\o}ller operators.

Generalized Information Matrix Tests for Detecting Model Misspecification

Econometrics, 2016
Generalized Information Matrix Tests (GIMTs) have recently been used for detecting the presence of misspecification in regression models in both randomized controlled trials and observational studies.

Asymptotic structure of perturbative series for $\tau$ lepton decay observables: $m_s^2$ corrections [PDF]

, 1999
In a previous paper we performed an analysis of asymptotic structure of perturbation theory series for semileptonic $\tau$-lepton decays in massless limit. We extend our analysis to the Cabibbo suppressed $\Delta S=1$ decay modes of the $\tau$ lepton. In

Consequences of Model Misspecification for Maximum Likelihood Estimation with Missing Data

Econometrics, 2019
Researchers are often faced with the challenge of developing statistical models with incomplete data. Exacerbating this situation is the possibility that either the researcher’s complete-data model or the model of the missing-data mechanism is ...

Validating a 2-mode asymptotic expansion in computational bifurcation theory (Before introducing HDN for differential operation)

Nihon Kikai Gakkai ronbunshu, 2015
For error-free computation of high-derivatives of mathematical functions used in engineering applications, hyper-dual numbers (HDN) are receiving much attention in computational mechanics.

Generalized Log-Normal Chain-Ladder

, 2018
We propose an asymptotic theory for distribution forecasting from the log normal chain-ladder model. The theory overcomes the difficulty of convoluting log normal variables and takes estimation error into account. The results differ from that of the over-

Black Hole Entropy Associated with Supersymmetric Sigma Model [PDF]

, 2003
By means of an identity that equates elliptic genus partition function of a supersymmetric sigma model on the $N$-fold symmetric product $S^N X$ of $X$ ($S^N X=X^N/S_N$, $S_N$ is the symmetric group of $N$ elements) to the partition function of a second ...

Roy Glauber and asymptotic diffraction theory

SciPost Physics Proceedings, 2020
This is a review of Glauber's asymptotic diffraction theory, in which diffractive scattering is described in terms of interference between semiclassical amplitudes, resulting from a stationary-phase approximation.

Asymptotic states of the bounce geometry

, 2005
We consider the question of asymptotic observables in cosmology. We assume that string theory contains a landscape of vacua, and that metastable de Sitter regions can decay to zero cosmological constant by bubble nucleation.

Robustness and Efficiency Considerations When Testing Process Reliability with a Limit of Detection

Mathematics
Processes in biotechnology are considered reliable if they produce samples satisfying regulatory benchmarks. For example, laboratories may be required to show that levels of an undesirable analyte rarely (e.g., in less than 5% of samples) exceed a ...
