Covering tori with squares

open access: yesJournal of Combinatorial Theory, Series A, 1973
AbstractWe find that an n × n toroidal checkerboard can be covered with ⌈nk⌈nk⌉⌉k × k squares, and no fewer. To prove this result we also need to prove that the unit Euclidean torus can be covered with ⌈α−1⌈α−1⌉⌉ squares of side α, and no fewer.

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

New Lie tori from Naoi tori

open access: yes
We define general Lie tori which generalize original Lie tori. We show that a Naoi torus is a general Lie torus. We give examples and prove several properties of general Lie tori.

Development of simple predictive models of tooth loss in the community setting

open access: yesJournal of Periodontology, EarlyView.
Abstract Background A simple tool for predicting the risk of tooth loss is considered valuable for the implementation of early preventive measures in community settings. This study aimed to establish a simple predictive model for tooth loss in a community‐dwelling Japanese population.

Eustachian Tube Opening in Children With and Without Cleft Palate and Association With Otitis Media

open access: yesThe Laryngoscope, EarlyView.
Using transnasal endoscopy in 50 children, structural abnormalities of the torus tubarius—particularly the posterior lip—were significantly more common in children with cleft palate than in those without (52% vs. 20%). Adenoid size, dynamic Eustachian tube opening visibility, and the Eustachian Tube Inflammation Scale correlated with middle ear status ...

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces
