Density Formula in Malliavin Calculus by Using Stein’s Method and Diffusions
MathematicsLet G be a random variable of functionals of an isonormal Gaussian process X defined on some probability space. Studies have been conducted to determine the exact form of the density function of the random variable G.

Twin pregnancies and the limits of the energetics of gestation and growth hypothesis
The Anatomical Record, EarlyView.Abstract The “Energetics of Gestation and Growth” (EGG) hypothesis proposes that human birth timing and the associated secondary altriciality of human newborns is determined by limits in maternal metabolic capacity. According to this model, labor is triggered when the increasing fetal energy requirements exceed the expectant mother's maximum sustained ...

The Anatomical Record, EarlyView.Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

AxiomsFor the hierarchical normal and normal-inverse-gamma model, we derive the Bayesian estimator of the variance parameter in the normal distribution under Stein’s loss function—a penalty function that treats gross overestimation and underestimation equally ...

Stochastic Systems, 2016 This paper provides an introduction to the Stein method framework in the context of steady-state diffusion approximations. The framework consists of three components: the Poisson equation and gradient bounds, generator coupling, and moment bounds ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton
The Anatomical Record, EarlyView.Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

The Anatomical Record, EarlyView.Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

The Anatomical Record, EarlyView.Abstract Sauropod dinosaurs achieved unprecedented terrestrial gigantism, raising questions about the biomechanical limits of bone under extreme gravitational loads. We estimated static gravitational pressures (Pg) on appendicular cortical bone in neosauropods, including diplodocoids, brachiosaurids, and titanosaurs.
