Orlicz–Pettis Theorem through Summability Methods

open access: yesMathematics, 2019
This paper unifies several versions of the Orlicz−Pettis theorem that incorporate summability methods. We show that a series is unconditionally convergent if and only if the series is weakly subseries convergent with respect to a regular linear ...

Development of a dental handpiece angle correction device

open access: yesBioMedical Engineering OnLine, 2018
Background Preparation of a uniform angle of walls is essential for making an ideal convergence angle in fixed prosthodontics. We developed a de novo detachable angle-correction apparatus for dental handpiece drills that could help the ideal tooth ...

General empirical Bayes wavelet methods and exactly adaptive minimax estimation

open access: yes, 2005
In many statistical problems, stochastic signals can be represented as a sequence of noisy wavelet coefficients. In this paper, we develop general empirical Bayes methods for the estimation of true signal.

Polychromatic Iterative Statistical Material Image Reconstruction for Photon-Counting Computed Tomography

open access: yesInternational Journal of Biomedical Imaging, 2016
This work proposes a dedicated statistical algorithm to perform a direct reconstruction of material-decomposed images from data acquired with photon-counting detectors (PCDs) in computed tomography. It is based on local approximations (surrogates) of the

Bayesian models for the determination of resonant frequencies in a DI diesel engine [PDF]

open access: yes, 2011
A time series method for the determination of combustion chamber resonant frequencies is outlined. This technique employs the use of Markov-chain Monte Carlo (MCMC) to infer parameters in a chosen model of the data.

Large cardinals and continuity of coordinate functionals of filter bases in Banach spaces

open access: yes, 2020
Assuming the existence of certain large cardinal numbers, we prove that for every projective filter $\mathscr F$ over the set of natural numbers, $\mathscr{F}$-bases in Banach spaces have continuous coordinate functionals.

Methodological Bases for Psychological Support of the Teacher at Various Stages of His / Her Professional and Personal Development

open access: yesРоссийский психологический журнал, 2016
The article deals with the problem of some methodological guidelines in the content of psychological support of teachers at the stages of professional and personal development. The analysis of the problem proceeds from the idea of the convergence of self-

Erd\H{o}s-Ulam ideals vs. simple density ideals

open access: yes, 2018
The main aim of this paper is to bridge two directions of research generalizing asymptotic density zero sets. This enables to transfer results concerning one direction to the other one. Consider a function $g\colon\omega\to [0,\infty)$ such that $\lim_{

Strong and uniform convergence in the teleportation simulation of bosonic Gaussian channels [PDF]

open access: yes, 2018
In the literature on the continuous-variable bosonic teleportation protocol due to [Braunstein and Kimble, Phys. Rev. Lett., 80(4):869, 1998], it is often loosely stated that this protocol converges to a perfect teleportation of an input state in the ...
