Protostellar collapse induced by compression. II: rotation and fragmentation

open access: yes, 2003
We investigate numerically and semi-analytically the collapse of low-mass, rotating prestellar cores. Initially, the cores are in approximate equilibrium with low rotation (the initial ratio of thermal to gravitational energy is $\alpha_0 \simeq 0.5 ...

Arresting Microphase Separation Encodes Material Mechanics by Sculpting Microarchitectures and Local Polymer Enrichment

open access: yesAdvanced Materials, EarlyView.
Microarchitecture sculpting via phase separation programs hydrogel mechanics by creating globular, inverse globular, and spinodal structures. Spinodal architectures deliver superior toughness and energy dissipation, while ionic modulation through single polymer phase separation offers a simple, scalable route to tune mechanical properties ...

Voxel-based Deep Point Cloud Geometry Compression

open access: yes, 2021
We present two learning-based methods for coding point clouds geometry. The two methods target lossy and lossless compression, respectively, and have in common the fact to use a voxel-based representation of geometry. This representation enables us to extend well-known architectures used for 2D image generation and compression to 3D. We show that, when
