Are 2I/Borisov and Oort Cloud Comets Alike? [PDF]
arXiv, 2019 The interstellar comet 2I/Borisov bears a strong resemblance to Oort Cloud comets, judging from its appearance in images taken over the first six weeks of observation. To test the proposed affinity in more diagnostic terms, 2I is compared to Oort Cloud comets of similar perihelion distance, near 2 AU.

Journal of Clinical Ultrasound, EarlyView.Our findings are given the increasing application of AI in medical imaging and the clinical necessity to improve the accuracy of thyroid nodule evaluation. The majority voting system combining C‐TIRADS, CEUS, and AI real‐time ultrasound‐assisted diagnosis achieved the highest diagnostic performance, with a sensitivity of 97% and specificity of 89 ...

Genotoxicity study of Ethiopian medicinal plant extracts on HepG2 cells
BMC Complementary and Alternative Medicine, 2018 Background Most of herbal medicines are used without any standard safety and toxicological trials although common assumption is that these products are nontoxic. However, this assumption is incorrect and dangerous, so toxicological studies should be done

The Dust Tail of Asteroid (3200) Phaethon
, 2013 We report the discovery of a comet-like tail on asteroid (3200) Phaethon when imaged at optical wavelengths near perihelion. In both 2009 and 2012, the tail appears >=350" (2.5x10^8 m) in length and extends approximately in the projected anti-solar ...

Modelling the light-curve of KIC 12557548b: an extrasolar planet with a comet like tail
, 2013 An object with a very peculiar light-curve was discovered recently using Kepler data. Authors argue that this object may be a transiting disintegrating planet with a comet like dusty tail. We calculate the light-curves of stars with such planets and take

physica status solidi (b), EarlyView.Novel Cu–Ni–Sn–S nanocrystals (NCs) stabilized with thioglycolic acid are synthesized in aqueous solutions. The structural and optical properties of Cu–Ni–Sn–S NCs are examined in colloidal solutions and thin films and compared to those of Cu–Zn–Sn–S NCs. The absorption coefficient is α > 104 cm−1 at 400 nm with an estimated Eg≈2.2 eV.
