From mice to humans—divergent strategies for intestinal homeostasis and regeneration
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 ...

Star clusters in unperturbed spiral galaxies
Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.

The concept of preferential atomic and molecular adsorption site is of primary relevance in heterogeneous catalysis. In the case of ultrasmall size‐selected clusters, distinguishing the role played by each atom in a reaction is extremely challenging due ...

Phosphoinositides and inositol phosphates as molecular glues
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Defending clusters against critics [PDF]
In recent years, almost everybody became interested in clusters. Companies, businessmen, scholars and policymakers alike seem to be fascinated by the clustering phenomenon and its potential to trigger, or to further stimulate, economic growth and ...

Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Clustering and Community Detection With Imbalanced Clusters
Spectral clustering methods which are frequently used in clustering and community detection applications are sensitive to the specific graph constructions particularly when imbalanced clusters are present. We show that ratio cut (RCut) or normalized cut (NCut) objectives are not tailored to imbalanced cluster sizes since they tend to emphasize cut ...

An International Comparison of National Clusters [PDF]
The presence of innovative clusters may positively influence domestic economic growth. If it is possible to identify these clusters, economic growth may be increased even further by developing policy that stimulates innovative clusters.

Clustering craftwork activities: An approach to promote regional development in a peripheral region of Portugal [PDF]
Portugal’s globalization and integration had positive repercussionsat the economic and social development level, but simultaneously it evidencedregional asymmetries, demanding new explanatory models to lessen existent disparities.Recent paradigms value ...
