Leprosy in wild armadillos

open access: yesLeprosy Review, 2005
Wild nine-banded armadillos (Dasypus novemcinctus) in the south central United States are highly endemic natural hosts of Mycobacterium leprae. Surveys conducted over the last 30 years on more than 5000 animals confirm that the infection is present among armadillos in Arkansas, Louisiana, Mississippi and Texas.

Interpolated Adaptive Linear Reduced Order Modeling for Deformation Dynamics

open access: yesComputer Graphics Forum, EarlyView.
Abstract Linear reduced‐order modeling (ROM) is widely used for efficient simulation of deformation dynamics, but its accuracy is often limited by the fixed linearization of the reduced mapping. We propose a new adaptive strategy for linear ROM that allows the reduced mapping to vary dynamically in response to the evolving deformation state ...

Contouring Signed Distance Fields by Approximating Gradients

open access: yesComputer Graphics Forum, EarlyView.
Abstract Signed distance fields are often represented by discrete samples (e.g., on a grid). Recovering the contour implicitly represented by the distance samples requires an approximation algorithm. Several recent approaches have shown that exploiting the information carried in each distance sample by explicitly constructing a surface point gives ...

Armadillos: antiguos mamíferos acorazados habitantes de las Américas [PDF]

open access: yes, 2018
Desde hace varios millones de años, un peculiar grupo de mamíferos habita nuestro continente, los armadillos, cuyo nombre alude a la “armadura” que recubre su cuerpo dorsalmente.

Affinification: A Fine Approximation of Deformations

open access: yesComputer Graphics Forum, EarlyView.
Abstract We introduce affinification, a novel method for accelerating physics‐based animation of elastic solids. During a time‐dependent simulation, our method automatically partitions the space into affine and elastic regions depending on the deformation.

Importance of xenarthrans in the eco-epidemiology of Paracoccidioides brasiliensis

open access: yesBMC Research Notes, 2009
Background Several pathogens that cause important zoonotic diseases have been frequently associated with armadillos and other xenarthrans. This mammal group typically has evolved on the South American continent and many of its extant species are ...

Progressively Projected Newton's Method

open access: yesComputer Graphics Forum, EarlyView.
Abstract Newton's Method is widely used to find the solution of complex non‐linear simulation problems. To guarantee a descent direction, it is common practice to clamp the negative eigenvalues of each element Hessian prior to assembly—a strategy known as Projected Newton (PN)—but this perturbation often hinders convergence.

Hierarchical Optimization of the As‐Rigid‐As‐Possible Energy

open access: yesComputer Graphics Forum, EarlyView.
Abstract The As‐Rigid‐As‐Possible (ARAP) energy [SA07] has become a versatile ingredient in various geometry processing and machine learning methods. The classic method for its minimization is a block coordinate descent, alternating between local rotation estimation and a global linear solve, which converges slowly for large problem instances.

Fast Nodal Hessian Computation for Peridynamic Fracture Simulation

open access: yesComputer Graphics Forum, EarlyView.
A fast, exact nodal Hessian computation for Non‐Ordinary State‐Based Peridynamics is introduced through analytical simplification and a warp‐centric GPU strategy. The method accelerates preconditioned solvers and Vertex Block Descent, enabling interactive fracture simulation with physical accuracy.

Dynamics of leprosy in Nine-Banded Armadillos: Net reproductive number and effects on host population dynamics

open access: yes, 2017
Leprosy (or Hansen’s disease) remains an important public health challenge globally, with an estimated 5.5 million total number of cases and 200,000–300,000 new cases reported annually.
