Comets in Australian Aboriginal Astronomy
, 2010 We present 25 accounts of comets from 40 Australian Aboriginal communities, citing both supernatural perceptions of comets and historical accounts of bright comets.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
The Anatomical Record, EarlyView.Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Rate of convergence for polymers in a weak disorder [PDF]
, 2016 We consider directed polymers in random environment on the lattice Z d at small inverse temperature and dimension d $\ge$ 3. Then, the normalized partition function W n is a regular martingale with limit W.

The Anatomical Record, EarlyView.Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Animal Research and One Health, EarlyView.Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

Thermal Evolution of the Nucleus of the Comet 67P for 120 Years: Numerical Simulations
Open Astronomy, 2018 The purpose of this paper is to estimate to what temperatures and to what depth the outer layers of the cometary nuclei are heated for several dozen revolutions around the Sun, and what changes in the composition of the volatiles occur in this case. This

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning
Cytoskeleton, EarlyView.ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Photoluminescence and Cathodoluminescence of the Solid Cometary Substance
Open Astronomy, 2019 We have proposed that solar ultraviolet and corpuscular radiations may excite photoluminescence and cathodoluminescence of the solid cometary substance including mineral halos of comets.

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays
Cytoskeleton, EarlyView.ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.

“Stars Falling to Earth”—Mental Models of Comets and Meteors
Education SciencesThe present study examines students’ conceptions of comets and meteors using qualitative research methods. A total of 35 semi-structured interviews were conducted with students in grades 7 and 9 in Germany, aiming to gain a richer understanding of how ...
