Adaptive Optical Layers: Efficient Tall Cell Grids for Liquid Simulation
Computer Graphics Forum, EarlyView.Abstract Tall cell grids have been proposed as an efficient approach to accelerate large‐scale liquid simulation. In this framework, regions near the liquid surface are discretized with regular grids, while regions farther away are represented by elongated rectangular cells.

Leprosy 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
Computer 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 ...

Major risk factors for leprosy in a non-endemic area of the United States: A case series
IDCases, 2019 Approximately 200 cases of leprosy are reported each year in the United States, and about 175 of the cases are diagnosed for the first time. Florida contributes a large number of reported cases each year and is showing an increasing incidence.

Contouring Signed Distance Fields by Approximating Gradients
Computer 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 ...

Frontiers in Immunology, 2018 1–5% of human blood T cells are Vγ9Vδ2 T cells whose T cell receptor (TCR) contain a TRGV9/TRGJP rearrangement and a TRDV2 comprising Vδ2-chain. They respond to phosphoantigens (PAgs) like isopentenyl pyrophosphate or (E)-4-hydroxy-3-methyl-but-2-enyl ...

Affinification: A Fine Approximation of Deformations
Computer 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.

Progressively Projected Newton's Method
Computer 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
Computer 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.

The Nine-banded Armadillo (Dasypus novemcinctus)
EDIS, 2003 Armadillos are prehistoric-looking animals that belong to a family of mammals found primarily in Central and South America. The earliest fossil ancestor of our North American armadillo occurred about 60 million years ago; it was as large as a rhinoceros.
