Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

A generalized coincidence point index
Applied General Topology, 2005 The paper is devoted to build for some pairs of continuous single-valued maps a coincidence point index. The class of pairs (f, g) satisfies the condition that f induces an epimorphism of the Cech homology groups with compact supports and coefficients in

Multivalued Common Fixed Points Theorem in Complex b-Metric Spaces
Mathematics, 2023 In this paper, we establish a result for the existence of common fixed points for multi-valued mappings, satisfying some contractions for complex-valued b-metric spaces. Finally, we present an example to illustrate and support our results.

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.

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

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

On a lower continuity of upper continuous mappings with values in the Sorgenfrey line(in Ukrainian)
Математичні Студії, 2013 We shown that for each lower continuous finite valued mapping from metrizable topological space $X$ inSorgenfrey line the set of points of upper continuous is residual in $X$.

Periodic points of multi-valued $\varepsilon $-contractive maps
Topological Methods in Nonlinear Analysis, 2003 Let \((X,d)\) be a nonempty metric space and let \((2^X,H_d)\) be the hyperspace of all nonempty compact subsets of \(X\) with the Hausdoff metric. A multivalued map \(F:X\to 2^X\) is said to be \(\varepsilon\)-contractive (\(\varepsilon>0\)) provided that for all \(x,y\in X\) with \(x\not= y\) and \(d(x,y)

Polyrhythmia of the smellwalk: mapping multi-scalar temporalities [PDF]
, 2017 Using research through design this project investigates the layers of rhythms experienced during a smellwalk through its subsequent mapping. The multi-scalar temporalities of the smellscape are revealed through conversations, notes, performance ...

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.
