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 ...

Isometry groups of non standard metric products
, 2013 We consider isometry groups of a fairly general class of non standard products of metric spaces. We present sufficient conditions under which the isometry group of a non standard product of metric spaces splits as a permutation group into direct or ...

Quasi-isometry classification of RAAGs that split over cyclic subgroups
, 2019 For a one-ended right-angled Artin group, we give an explicit description of its JSJ tree of cylinders over infinite cyclic subgroups in terms of its defining graph. This is then used to classify certain right-angled Artin groups up to quasi-isometry. In

Allometric Growth and Scaling of Body Form of the Spadenose Shark (Scoliodon laticaudus)
Ecology and EvolutionThe versatility of the shark body form is suggested to be one of the key factors underlying their evolutionary success and persistence. Nevertheless, sharks exhibit a huge diversity of body forms and morphological adaptations.

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs
The Anatomical Record, EarlyView.Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Isometry-invariant geodesics and the fundamental group
, 2015 International audienceWe prove that on closed Riemannian manifolds with infinite abe-lian, but not cyclic, fundamental group, any isometry that is homotopic to the identity possesses infinitely many invariant geodesics.

A New Method for Constructing Self-Dual Codes over Finite Commutative Rings with Characteristic 2
MathematicsIn this work, we present a new method for constructing self-dual codes over finite commutative rings R with characteristic 2. Our method involves searching for k×2k matrices M over R satisfying the conditions that its rows are linearly independent over R

Nontrivial isometries on sp(α)
International Journal of Mathematics and Mathematical Sciences, 1982 sp(α) is a Banach space of sequences x with ‖x‖=(∑i=0∞|xi|p+α∑i=0∞|xi+1−xi|p)1/p.

Stem Diameter (and Not Length) Limits Twig Leaf Biomass
Frontiers in Plant Science, 2019 The relationship between leaf and stem biomass as well as the relationship between leaf biomass and stem length and diameter are important to our understanding of a broad range of important plant scaling relationship because of their relationship to ...

The Anatomical Record, EarlyView.Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...
