The rate of convergence of a modified Newton's process [PDF]
, 1925 summary:In this paper we introduce the notion of "$p$-dimensional rate of convergence" which generalizes the notion of rate of convergence introduced by V. Pták. Using this notion we give a generalization of the Induction Theorem of V.

On the Bounds for a Two-Dimensional Birth-Death Process with Catastrophes
Mathematics, 2018 The model of a two-dimensional birth-death process with possible catastrophes is studied. The upper bounds on the rate of convergence in some weighted norms and the corresponding perturbation bounds are obtained.

On the rate of convergence for a class of Markovian queues with group services
Discrete and Continuous Models and Applied Computational Science, 2020 There are many queuing systems that accept single arrivals, accumulate them and service only as a group. Examples of such systems exist in various areas of human life, from traffic of transport to processing requests on a computer network. Therefore, our

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

Convergence, competitiveness and the exchange rate
, 1996 Standard theory predicts that exchange rate changes have merely temporary real effects. Yet, if the higher profits that a devaluation ensures are used to improve non-price competitiveness, longer-run effects are possible. The paper looks at the experience of Germany, Spain, France and Italy which, in the 1950s and 1960s, either benefited from low ...

Molecular Oncology, EarlyView.In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...

Explaining Exchange Rate Movements in New Member States of the European Union: Nominal and Real Convergence [PDF]
This paper uses the univariate and bivariate structural VAR variance framework to quantify real and nominal exchange rate volatility in the selective New Member States of the European Union, and identify factors responsible for movements of those rates ...

Nonstationary Queues: Estimation of the Rate of Convergence
Queueing Systems, 2004 The paper is devoted to the estimation of the rate of of exponential convergence of nonhomogeneous queues exhibiting different types of ergodicity. The main tool of our study is the method, which was proposed by the second author in the late 1980-s and was subsequently extended and developed in different directions in a series of joint papers by the ...

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
