Completely Positive Maps of the Cuntz Algebras
Journal of Functional Analysis, 1997 The author constructs a covariant functor from the category whose objects are separable Hilbert spaces and whose morphisms are contractions, into the category whose objects are unital \(C^*\)-algebras and whose morphisms are completely positive, identity preserving maps.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Modelling stem cell differentiation related processes—A practical overview for biologists
FEBS Letters, EarlyView.Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Nuclearity and ${\mathrm {CPC}^*}$ -Systems
Forum of Mathematics, SigmaWe write arbitrary separable nuclear $\mathrm {C}^*$ -algebras as limits of inductive systems of finite-dimensional $\mathrm {C}^*$ -algebras with completely positive connecting maps. The characteristic feature of such ${\mathrm {CPC}^*}$

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Two-qubit causal structures and the geometry of positive qubit-maps
New Journal of Physics, 2018 We study quantum causal inference in a setup proposed by Ried et al (2015 Nat. Phys. 11 414) in which a common cause scenario can be mixed with a cause–effect scenario, and for which it was found that quantum mechanics can bring an advantage in ...

Special classes of positive and completely positive maps
Linear Algebra and its Applications, 1997 Many authors have studied the problem of characterising the positive and completely positive maps on square complex matrices of size \(n\) under certain invariant conditions. These authors have characterized the above mentioned maps that leave invariant the diagonal or the \(k\)th elementary symmetric functions of the diagonal entries, for \(1 < k \leq
