Ergodic measure preserving transformations with quasi-discrete spectrum
, 1974 It is shown that an ergodic measure preserving transformation with quasi-discrete spectrum is conjugate to: (a) the skew-product of an ergodic measure preserving transformation with discrete spectrum and a measurable family of totally ergodic measure ...

Semigroups of order-decreasing transformations [PDF]
, 2012 Let X be a totally ordered set and consider the semigroups of orderdecreasing (increasing) full (partial, partial one-to-one) transformations of X. In this Thesis the study of order-increasing full (partial, partial one-to-one) transformations has been

Shape preserving piecewise rational interpolation [PDF]
, 1983 An explicit representation of a C1 piecewise rational cubic function is developed which can be used to solve the problem of shape preserving interpolation.

International Journal for Research in Vocational Education and Training, 2021 Context: Dual VET systems are often praised for their labour market proximity because of economic stakeholders’ involvement. However, when labour market requirements change rapidly, a lack of flexibility is attributed to them.

Degree of recurrence of generic diffeomorphisms
Discrete Analysis, 2019 Degree of recurrence of generic diffeomorphisms, Discrete Analysis 2019:1, 43 pp. The theory of discrete-time dynamical systems concerns iterations of maps $f:X\to X$, where $X$ is a space of some kind (e.g.

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 ...

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.

A decomposition of multicorrelation sequences for commuting transformations along primes
Discrete Analysis, 2021 A decomposition of multicorrelation sequences for commuting transformations along primes, Discrete Analysis 2021:4, 27 pp. Szemerédi's theorem asserts that for every positive integer $k$ and every $\delta>0$ there exists $n$ such that every subset of $\

On orbits under ergodic measure-preserving transformations [PDF]
Transactions of the American Mathematical Society, 1965 Let \(I\) be the unit interval with Lebesgue measure and let \(T\) be a 1-1 measure-preserving ergodic transformation mapping \(I\) onto \(I\). Intuitively one feels that the orbit \(\{T^nx\}\) of a ``general'' point \(x\in I\) should somehow determine \(T\). This notion is made precise in this paper.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
