We give a classification of substructures (= closed subbifunctors) given skeletally small extriangulated category by using the defects, in similar way to author’s exact structures additive category. More precisely, for an category, possible are bijection with Serre subcategories abelian consisting defects conflations. As byproduct, we prove that poset on it is isomorphic some

We show that for a given exact category, there exists bijection between semibricks (pairwise Hom-orthogonal set of bricks) and length wide subcategories (exact extension-closed abelian subcategories). In particular, we category is if only simple objects form semibrick, is, the Schur's lemma holds.

INTRODUCTION Communication is one of the key principles in Family-Centered Care (FCC). Studies have shown some drawbacks in communication between families and nurses. Therefore, the present study aimed to recognize the obstacles against nurse-family communication in FCC in Neonatal Intensive Care Unit (NICU). METHODS This qualitative study was conducted on 8 staff nurses in 2 NICUs affiliated...

Studies show that refining real-world categories into semantic subcategories contributes to better image modeling and classification. Previous image sub-categorization work relying on labeled images and WordNet’s hierarchy is not only laborintensive, but also restricted to classify images into NOUN subcategories. To tackle these problems, in this work, we exploit general corpus information to a...

Human ejaculates contain extracellular vesicles (EVs), that to a large extent are considered to originate from the prostate gland, and are often denominated "prostasomes." These EVs are important for human fertility, for example by promoting sperm motility and by inducing immune tolerance of the female immune system to the spermatozoa. So far, the EVs present in human ejaculate have not been st...
