Positivity for Convective Semi-discretizations

, 2018
We propose a technique for investigating stability properties like positivity and forward invariance of an interval for method-of-lines discretizations, and apply the technique to study positivity preservation for a class of TVD semi-discretizations of ...

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

Total-positivity preservers

, 2017
This paper is being completely rewritten, with the focus now on kernels on arbitrary domains, and the ensuing analysis. This includes Polya frequency functions/sequences, Hankel and other Toeplitz kernels, and the study of their ...

EMAS position statement: Fertility preservation

Maturitas, 2014
The increasing incidence of malignant diseases that often require gonadotoxic treatment and the tendency to become a parent later in life result in an increased need for fertility preservation.The aim of this position statement is to provide and critically appraise evidence on available options for fertility preservation in both pre-pubertal and post ...

Total positivity of Hadamard products

, 1992
The Hadamard product of two totally positive Toeplitz matrices M and N need not be totally positive. When only finitely many diagonals of M and of N are non-zero, preservation of total positivity by Hadamard product is essentially a theorem of Maló. Here

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

A Positivity-Preserving Relaxation Algorithm

CoRR
We combine Patankar-type methods with suitable relaxation procedures that are capable of ensuring correct dissipation or conservation of functionals such as entropy or energy while producing unconditionally positive and conservative approximations. To that end, we adapt the relaxation algorithm to enforce positivity by using either ideas from the dense

Clinical and genetic characteristics of people with type 1 diabetes who have discrepancies in titers of anti‐glutamic acid decarboxylase antibody measured by radioimmunoassay and enzyme‐linked immunosorbent assay

Journal of Diabetes Investigation, 2020
Aims/Introduction The aim of the present study was to compare the clinical and genetic characteristics between people with type 1 diabetes who were positive and negative for autoantibodies against glutamic acid decarboxylase (GADA) measured by enzyme ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
