Partial identification with categorical data and nonignorable missing outcomes

Canadian Journal of Statistics, EarlyView.
Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.

Increasing degree of validity of decision support in the recognition system at the expense of the using of priori information

Научный вестник МГТУ ГА, 2016
An approach is proposed for solution of the problem for increasing the effectiveness of the recognition of the car number plate by using a priori information.

Numerical solution and errors analysis of iterative method for a nonlinear plate bending problem

Results in Applied Mathematics
This paper uses the HCT finite element method and mesh adaptation technology to solve the nonlinear plate bending problem and conducts error analysis on the iterative method, including a priori and a posteriori error estimates. Our investigation exploits

Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure

A quoi sert la modalisation a posteriori ?

Anglophonia, 2015
This paper explores Paul Larreya’s concept of a posteriori modalisation. We first come back on Larreya’s distinction between a priori and a posteriori modalisation and suggest that his typology of the uses and functions of a posteriori modalisation ...

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Addressing Causality and Homogeneity Assumptions in Exposure‐Response Analyses

Clinical Pharmacology &Therapeutics, EarlyView.
Exposure‐response, or pharmacokinetic–pharmacodynamic (PKPD), analyses support many drug development decisions. It is typically applied without assessment of causality and homogeneity, where the latter refers to the assumption that the reason for variability in exposure is unimportant for the impact on response.

A Type of Multigrid Method Based on the Fixed-Shift Inverse Iteration for the Steklov Eigenvalue Problem

Advances in Mathematical Physics, 2016
For the Steklov eigenvalue problem, we establish a type of multigrid discretizations based on the fixed-shift inverse iteration and study in depth its a priori/a posteriori error estimates.
