Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development
Advanced Science, Volume 13, Issue 19, 2 April 2026.This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

Real-time algorithms implemented in hardware for centroiding on A Shack-Hartmann sensor
, 2015 A Shack-Hartmann wavefront sensor processes images formed by an array of lenses to determine the local gradient of the wavefront using simple centroiding algorithms.

PROTEOMICS, Volume 26, Issue 4, Page 36-48, April 2026.ABSTRACT To assess the potential for high resolution ion mobility (HRIM) as an alternative means of precursor isolation for mass spectrometry fragmentation analysis we performed a meta‐analysis of predicted tryptic peptide features from the human proteome to measure the rate of chimeric spectrum generation relative to traditional quadrupole‐based ...

On the centroid of increasing trees
Discrete Mathematics & Theoretical Computer Science, 2019 A centroid node in a tree is a node for which the sum of the distances to all other nodes attains its minimum, or equivalently a node with the property that none of its branches contains more than half of the other nodes. We generalise some known results regarding the behaviour of centroid nodes in random recursive trees (due to Moon) to the class of ...

Phytochemical diversity of naturally regenerated plants in a biodiversity enrichment experiment
Journal of Ecology, Volume 114, Issue 3, March 2026.Tree islands established within an industrial oil palm plantation promoted the recovery of phytochemical diversity through natural regeneration. Ten years after planting, untargeted metabolomics of 76 regenerating woody species detected 27,122 phytochemical features, including many novel compounds. Larger islands supported higher woody species richness

Optimised centroiding of stars for space applications
, 2016 Für die Ausrichtung und Nachführung von Weltraumteleskopen sind meist hochpräzise Positionsangaben des Zielobjekts notwendig. Diese Positionsinformationen können aus Bildern durch die Anwendung von Zentrierungsalgorithmen extrahiert werden.
