Generalization of Cycle Decompositions of Even Dimensional Hypercubes on $d$-Dimensional Toruses [PDF]

arXiv
We consider cycle decompositions of even, $2an$-dimensional hypercubes $Q_{2an},$ where $a \geq 3$ is odd and $n \geq 1.$ Prior work done by Axenovich, Offner, and Tompkins focused on obtaining the existence of cycle decompositions for even-dimensional hypercubes using long cycles of a given form, leaving out cycles of shorter lengths and, in fact ...

Daytime sleepiness and BMI exhibit gender and age differences in patients with central disorders of hypersomnolence

Journal of Sleep Research, EarlyView.
In a cohort of central disorders of hypersomnolence, specifically women with idiopathic hypersomnia showed a marked subjective daytime sleepiness peak in the early 30s, while the body mass index only started to rise at that age. Better understanding of the pathophysiology of these gender and age‐specific characteristics will support tailored ...

Disruption and irruption shape genetic variation and population structure of the common rock‐rat in north‐western Australia

Journal of Zoology, EarlyView.
The most abundant and widespread of Australia's rock‐rats shows marked genetic diversity, with the Great Sandy Desert marking a long‐standing genetic dichotomy between populations in the monsoonal and arid biomes. Genetically depauperate relictual island populations formed from 10 ky bp are divergent but nonetheless align with mainland cognates, and ...

Features of reproduction and assisted reproduction in the white (Ceratotherium simum) and black (Diceros bicornis) rhinoceros [PDF]

, 2015
Despite the worldwide increase of rhinoceros calf numbers, the growth of the population of white and black rhinoceros is slowing down mainly due to anthropogenic causes, such as poaching and habitat loss.

Mating system variation and gene expression in the male reproductive tract of Peromyscus mice

Molecular Ecology, EarlyView.
Abstract Genes involved in reproduction often evolve rapidly at the sequence level due to postcopulatory sexual selection (PCSS) driven by male–male competition and male–female sexual conflict, but the impact of PCSS on gene expression has been under‐explored.
