On the Rate of Moment Convergence for a Normalized Random Walk

, 2012
[[abstract]]In this paper, we study the convergence rate of the r-th moments of a normalized simple random walk. When r = 1, we use the discrete-time version of Ito-Tanaka formula to obtain an exact convergence rate.

On rate of convergence of various iterative schemes

Fixed Point Theory and Applications, 2011
In this note, by taking an counter example, we prove that the iteration process due to Agarwal et al. (J. Nonlinear Convex. Anal. 8 (1), 61-79, 2007) is faster than the Mann and Ishikawa iteration processes for Zamfirescu operators.

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Hitting and Hoping? Meeting the Exchange Rate and Inflation Criteria during a Period of Nominal Convergence [PDF]

This paper analyses the problem faced by CEECs wishing to join the Euro who must hit both an inflation and exchange rate criterion during a period of nominal convergence.

Approximation by weighted means of Walsh-Fourier series

International Journal of Mathematics and Mathematical Sciences, 1996
We study the rate of approximation to functions in Lp and, in particular, in Lip(α,p) by weighted means of their Walsh-Fourier series, where α>0 and 1≤p≤∞.

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Does the Inflation Targeting Have a Positive Role upon the Convergence of the Inflation Rate? [PDF]

This article asks whether the monetary regime of inflation targeting that Romania chose is favorable to the inflation convergence with the EU. We analyze a few of the standard models of inflation convergence and apply some of them for the case of Romania.

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Nominal and Real Convergence in Alternative Exchange Rate Regimes in Transition Countries: Implications for the EMU Accession [PDF]

This paper discusses the processes of nominal and real convergence and their dependence on exchange rate regimes adopted in Central and Eastern European countries (CEECs) in the context of their future EMU accession.
