The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

, 2000 We consider the Schrödinger operator H=−Δ2+q in a bounded domain D in Rd, d≥3, with q in the Kato class Kd(D) and finite gauge g(x)=Ex[exp∫τ0q(Xs)ds], where (Xt) is a Brownian motion and τ is the first exit time of the Brownian motion (Xt) from the ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Geodesics in Brownian surfaces (Brownian maps)
Annales de l'Institut Henri Poincaré, Probabilités et Statistiques, 2016 We define a class a metric spaces we call Brownian surfaces, arising as the scaling limits of random maps on general orientable surfaces with a boundary and we study the geodesics from a uniformly chosen random point. These metric spaces generalize the well-known Brownian map and our results generalize the properties shown by Le Gall on geodesics in ...

Hastings-Levitov aggregation in the small-particle limit [PDF]
, 2011 We establish some scaling limits for a model of planar aggregation. The model is described by the composition of a sequence of independent and identically distributed random conformal maps, each corresponding to the addition of one particle. We study the

The Anatomical Record, EarlyView.Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Convex Hull of Brownian Motion and Brownian Bridge
Markov Processes And Related FieldsIn this article we study the convex hull spanned by the union of trajectories of a standard planar Brownian motion, and an independent standard planar Brownian bridge. We find the exact values of the expectation of perimeter and area of such a convex hull.

A simple characterization of dynamic completeness in continuous time [PDF]
, 2013 Under review (second round) by Mathematical Finance (Online ISSN: 1467-9965)This paper investigates dynamic completeness of financial markets in which the underlying risk process is a multi-dimensional Brownian motion and the risky securities' dividends ...

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes
The Anatomical Record, EarlyView.Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.
