Trotter-Kato product formulae in Dixmier ideal

open access: yes, 2018
It is shown that for a certain class of the Kato functions the Trotter-Kato product formulae converge in Dixmier ideal C 1,$\infty$ in topology, which is defined by the $\times$ 1,$\infty$-norm. Moreover, the rate of convergence in this topology inherits

On the Estimation Performance and Convergence Rate of the Generalized Power Method for Phase Synchronization [PDF]

open access: yesSIAM Journal on Optimization, 2016
An estimation problem of fundamental interest is that of phase synchronization, in which the goal is to recover a collection of phases using noisy measurements of relative phases.

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

On the estimation of the convergence rate in the multidimentional limit theorem for the sum of weakly dependent random variables functions

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2018
A refinement of estimates of the convergence rate obtained earlier in the multidimensional central limit theorem for the sums of vectors generated by the sequences of random variables with mixing is close to optimal. This has been achieved by imposing an

A Quasi-Boundary Value Method for Solving a Backward Problem of the Fractional Rayleigh–Stokes Equation

open access: yesAxioms
In this paper, we study a backward problem for a fractional Rayleigh–Stokes equation by using a quasi-boundary value method. This problem is ill-posed; i.e., the solution (if it exists) does not depend continuously on the data.

Regression Estimation with Errors in the Variables via the Laplace Transform

open access: yesAxioms, 2023
This paper considers nonparametric regression estimation with errors in the variables. It is a standard assumption that the characteristic function of the covariate error does not vanish on the real line. This assumption is rather strong.

A rate of convergence in clustering analysis [PDF]

open access: yes, 1992
We present a result about stochastic boundedness of stable empirical processes on Vapnik-Cervonenkis classes of functions and we apply it to obtain a rate of convergence for the approximation between the sample and the populational variation in the k ...

Convergence rate of Krasulina estimator [PDF]

open access: yesStatistics & Probability Letters, 2019
Principal component analysis (PCA) is one of the most commonly used statistical procedures with a wide range of applications. Consider the points $X_1, X_2,..., X_n$ are vectors drawn i.i.d. from a distribution with mean zero and covariance $ $, where $ $ is unknown. Let $A_n = X_nX_n^T$, then $E[A_n] = $. This paper consider the problem of finding

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Interest Rate Convergence in Bangladesh

open access: yesThe International Journal of Banking and Finance, 2012
Financial liberalization, a widely-accepted policy paradigm since the 1980s, aims to remove financial repression and thus establish an efficient financial sector as a pre-requisite for financial development.
