Computing recurrence coefficients of multiple orthogonal polynomials [PDF]

open access: yesNumerical Algorithms 70 (2015), no. 3, 519-543, 2015
Multiple orthogonal polynomials satisfy a number of recurrence relations, in particular there is a $(r+2)$-term recurrence relation connecting the type II multiple orthogonal polynomials near the diagonal (the so-called step-line recurrence relation) and

Powers of sequences and recurrence [PDF]

open access: yes, 2007
We study recurrence, and multiple recurrence, properties along the $k$-th powers of a given set of integers. We show that the property of recurrence for some given values of $k$ does not give any constraint on the recurrence for the other powers. This is

Variations on topological recurrence [PDF]

open access: yesarXiv, 2014
Recurrence properties of systems and associated sets of integers that suffice for recurrence are classical objects in topological dynamics. We describe relations between recurrence in different sorts of systems, study ways to formulate finite versions of

On the Strong Recurrence of Recurrent RWRE [PDF]

open access: yesarXiv, 2012
We consider a recurrent RWRE $(X_n)_{n \in \mathbb{N}_0}$ on $\mathbb{Z}$ and investigate the quenched return probabilities of the RWRE to the origin for which we state results on their decay in terms of summability. Additionally, we give some examples for recurrent RWRE with a multidimensional state space which give reason for the part "strong ...

Evaluating the efficacy of secondary transurethral resection of the bladder for high-grade Ta tumors [PDF]

open access: yesInvestigative and Clinical Urology, 2022
Purpose: The need for secondary transurethral resection of the bladder (re-TURB) in patients with high-grade Ta tumors has not been assessed. This study aimed to compare the outcomes of patients with high-grade Ta tumors who did and did not undergo re ...

Comprehensive analysis of complement-associated molecular features in hepatocellular carcinoma

open access: yesActa Biochimica et Biophysica Sinica, 2022
The complement cascade plays a “complementing” role in human immunity. However, the potential roles of complement system in impacting molecular and clinical features of hepatocellular carcinoma (HCC) remain unclear.

Cystathionine β-synthase mediated PRRX2/IL-6/STAT3 inactivation suppresses Tregs infiltration and induces apoptosis to inhibit HCC carcinogenesis

open access: yesJournal for ImmunoTherapy of Cancer, 2021
Background Hepatocellular carcinoma (HCC) is characterized by inflammation and immunopathogenesis. Accumulating evidence has shown that the cystathionine β-synthase/hydrogen sulfide (CBS/H2S) axis is involved in the regulation of inflammation.

Recurrent recurrent gallstone ileus [PDF]

open access: yesThe Annals of The Royal College of Surgeons of England, 2010
We describe the second reported case of three consecutive episodes of gallstone ileus and ask the question whether recurrent gallstone ileus justifies definitive surgery to the fistula itself or can be safely managed by repeated enterotomies.

Fetal heart rate evolution patterns in cerebral palsy associated with umbilical cord complications: a nationwide study

open access: yesBMC Pregnancy and Childbirth, 2022
Background The aim of the present study was to clarify fetal heart rate (FHR) evolution patterns in infants with cerebral palsy (CP) according to different types of umbilical cord complications.
