Revisiting the Unified Model of Active Galactic Nuclei [PDF]
This review describes recent developments related to the unified model of active galactic nuclei (AGNs). It focuses on new ideas about the origin and properties of the central obscurer (torus) and the connection to its surroundings.

CIA-Net: Robust Nuclei Instance Segmentation with Contour-aware Information Aggregation
Accurate segmenting nuclei instances is a crucial step in computer-aided image analysis to extract rich features for cellular estimation and following diagnosis as well as treatment. While it still remains challenging because the wide existence of nuclei

Nuclei Instance Segmentation and Classification in Histopathology Images with Stardist [PDF]
Instance segmentation and classification of nuclei is an impor-tant task in computational pathology. We show that StarDist, a deep learning nuclei segmentation method originally devel-oped for fluorescence microscopy, can be extended and suc-cessfully ...

Calciprotein particles (CPPs) are indispensable scavengers of excessive Ca2+ and PO43− ions in blood, being internalised and recycled by liver and spleen macrophages, monocytes, and endothelial cells (ECs).

The possibility of radiation of high-energy gamma quanta with energies of the order of 100 GeV by ultrarelativistic electrons on nuclei in strong X-ray fields with intensities up to ∼1027Wcm−2 was theoretically studied.

Plants possess the most highly compartmentalized eukaryotic cells. To coordinate their intracellular functions, plastids and the mitochondria are dependent on the flow of information to and from the nuclei, known as retrograde and anterograde signals ...

UNIFIED SCHEMES FOR RADIO-LOUD ACTIVE GALACTIC NUCLEI [PDF]
The appearance of active galactic nuclei (AGN) depends so strongly on orientation that our current classification schemes are dominated by random pointing directions instead of more interesting physical properties.

Weakly Supervised Deep Nuclei Segmentation Using Partial Points Annotation in Histopathology Images [PDF]
Nuclei segmentation is a fundamental task in histopathology image analysis. Typically, such segmentation tasks require significant effort to manually generate accurate pixel-wise annotations for fully supervised training.
