A Concise and Provably Informative Multi‐Scale Signature Based on Heat Diffusion
We propose a novel point signature based on the properties of the heat diffusion process on a shape. Our signature, called the Heat Kernel Signature (or HKS), is obtained by restricting the… Expand
Defining and computing curve-skeletons with medial geodesic function
Many applications in geometric modeling, computer graphics, visualization and computer vision benefit from a reduced representation called curve-skeletons of a shape. These are curves possibly with… Expand
Genome sequences of three agrobacterium biovars help elucidate the evolution of multichromosome genomes in bacteria.
The family Rhizobiaceae contains plant-associated bacteria with critical roles in ecology and agriculture. Within this family, many Rhizobium and Sinorhizobium strains are nitrogen-fixing plant… Expand
Discrete laplace operator on meshed surfaces
In recent years a considerable amount of work in graphics and geometric optimization used tools based on the Laplace-Beltrami operator on a surface. The applications of the Laplacian include mesh… Expand
Global Intrinsic Symmetries of Shapes
Although considerable attention in recent years has been given to the problem of symmetry detection in general shapes, few methods have been developed that aim to detect and quantify the intrinsic… Expand
An adaptive MLS surface for reconstruction with guarantees
Recent work have shown that moving least squares (MLS) surfaces can be used effectively to reconstruct surfaces from possibly noisy point cloud data. Several variants of MLS surfaces have been… Expand
Constructing Laplace operator from point clouds in Rd
We present an algorithm for approximating the Laplace-Beltrami operator from an arbitrary point cloud obtained from a k-dimensional manifold embedded in the d-dimensional space. We show that this PCD… Expand
Co-spread of metal and antibiotic resistance within ST3-IncHI2 plasmids from E. coli isolates of food-producing animals
Concerns have been raised in recent years regarding co-selection for antibiotic resistance among bacteria exposed to heavy metals, particularly copper and zinc, used as growth promoters for some… Expand

Towards Understanding MCR-like Colistin Resistance.
Antibiotic resistance has become a global public health priority. Polymyxins, a family of cationic polypeptide antibiotics, act as a final line of refuge against severe infections by Gram-negative… Expand
