Formation of embryos of the Earth and the Moon from the common rarefied condensation and their subsequent growth [PDF]

open access: yesSolar System Research, 2018, v. 52, N 5, p. 401-416, 2020
Embryos of the Moon and the Earth may have formed as a result of contraction of a common parental rarefied condensation. The required angular momentum of this condensation could largely be acquired in a collision of two rarefied condensations producing the parental condensation. With the subsequent growth of embryos of the Moon and the Earth taken into

Robust and generalizable embryo selection based on artificial intelligence and time-lapse image sequences [PDF]

open access: yes, 2021
Assessing and selecting the most viable embryos for transfer is an essential part of in vitro fertilization (IVF). In recent years, several approaches have been made to improve and automate the procedure using artificial intelligence (AI) and deep learning.

Ethical Implementation of Artificial Intelligence to Select Embryos in In Vitro Fertilization [PDF]

open access: yesAIES 2021, 2021
AI has the potential to revolutionize many areas of healthcare. Radiology, dermatology, and ophthalmology are some of the areas most likely to be impacted in the near future, and they have received significant attention from the broader research community. But AI techniques are now also starting to be used in in vitro fertilization (IVF), in particular

THE IDENTIFICATION OF CHROMOSOMAL POLYMORPHISM IN ONE BREED OF IRAQI SHEEP

open access: yesThe Iraqi Journal of Veterinary Medicine, 1989
A chromosomal analysis of three breeds of Iraqi sheep (Karadi Arabi and Awassi) has been performed on peripheral lymphocytes. The modal chromosome number of all the three breeds was found to be (2n=54XX/54XY) for femal and male respectively.

Probabilities of collisions of planetesimals from different regions of the feeding zone of the terrestrial planets with the forming planets and the Moon [PDF]

open access: yesSolar System Research, 2019, v. 53, N 5, p. 332-361, 2020
Migration of planetesimals from the feeding zone of the terrestrial planets, which was divided into seven regions depending on the distance to the Sun, was simulated. The influence of gravity of all planets was taken into account. In some cases, the embryos of the terrestrial planets rather than the planets themselves were considered; their masses were

Correlation of Adiponectin mRNA Abundance and Its Receptors with Quantitative Parameters of Sperm Motility in Rams [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2016
Background Adiponectin and its receptors (AdipoR1 and AdipoR2), known as adiponectin system, have some proven roles in the fat and glucose metabolisms. Several studies have shown that adiponectin can be considered as a candidate in linking metabolism to ...
