PolyNet: Polynomial Neural Network for 3D Shape Recognition with PolyShape Representation [PDF]
2021 International Conference on 3D Vision (3DV), 2021 3D shape representation and its processing have substantial effects on 3D shape recognition. The polygon mesh as a 3D shape representation has many advantages in computer graphics and geometry processing. However, there are still some challenges for the existing deep neural network (DNN)-based methods on polygon mesh representation, such as handling ...

Mesh Draping: Parametrization-Free Neural Mesh Transfer [PDF]
arXiv, 2021 Despite recent advances in geometric modeling, 3D mesh modeling still involves a considerable amount of manual labor by experts. In this paper, we introduce Mesh Draping: a neural method for transferring existing mesh structure from one shape to another.

Optimizing Metamaterial Inverse Design with 3D Conditional Diffusion Model and Data Augmentation
Advanced Materials Technologies, EarlyView.A generative AI model, the 3D conditional diffusion model (3D‐CDM), is introduced to enhance the inverse design of voxel‐based metamaterials. A data augmentation technique based on topological perturbation expands the dataset, further improving generation quality and accuracy.

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%
Advanced Robotics Research, EarlyView.Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

State of the Art of Low‐Frequency Acoustic Modulation: Intensity Enhancement and Directional Control
Advanced Science, EarlyView.High intensity low‐frequency sound sources hold significant value in many fields. However, their long wavelength, strong penetrability, and tendency to diffract make direction control and intensity enhancement challenging. Acoustic generators and metamaterial‐based acoustic devices still face issues such as low energy efficiency, poor directional ...

Quivers with relations arising from clusters (A_n case)
, 2004 Cluster algebras were introduced by S. Fomin and A. Zelevinsky in connection with dual canonical bases. Let U be a cluster algebra of type A_n. We associate to each cluster C of U an abelian category Cat_C such that the indecomposable objects of Cat_C ...

Longitudinal, Multimodal Tracking Reveals Lasting Neurovascular Impact of Individual Microinfarcts
Advanced Science, EarlyView.Jin et al. investigate the neurovascular impact of microinfarcts, revealing transient neural suppression with minimal cell death and recovery linked to vascular remodeling. Fast‐spiking interneurons exhibit reduced excitability, whereas regular‐spiking neurons showed increased bursting activity. Disruptions in low‐gamma phase locking suggest persistent
