Optimal Model Mapping for Intravoxel Incoherent Motion MRI
Frontiers in Human Neuroscience, 2021 In general, only one diffusion model would be applied to whole field-of-view voxels in the intravoxel incoherent motion-magnetic resonance imaging (IVIM-MRI) study.

Compact 3D Gaussian Representation for Radiance Field [PDF]
Computer Vision and Pattern Recognition, 2023 Neural Radiance Fields (NeRFs) have demonstrated re-markable potential in capturing complex 3D scenes with high fidelity. However, one persistent challenge that hin-ders the widespread adoption of NeRFs is the computational bottleneck due to the ...

GaussianEditor: Swift and Controllable 3D Editing with Gaussian Splatting [PDF]
Computer Vision and Pattern Recognition, 2023 3D editing plays a crucial role in many areas such as gaming and virtual reality. Traditional 3D editing methods, which rely on representations like meshes and point clouds, often fall short in realistically depicting complex scenes.

Hypergeometric-Gaussian modes [PDF]
Optics Letters, 2007 We studied a novel family of paraxial laser beams forming an overcomplete yet nonorthogonal set of modes. These modes have a singular phase profile and are eigenfunctions of the photon orbital angular momentum. The intensity profile is characterized by a single brilliant ring with the singularity at its center, where the field amplitude vanishes.

Are the program packages for molecular structure calculations really black boxes? [PDF]
Journal of the Serbian Chemical Society, 2007 In this communication it is shown that the widely held opinion that compact program packages for quantum-mechanical calculations of molecular structure can safely be used as black boxes is completely wrong.

Physical Review E, 2013 A finite quantum system evolving unitarily equilibrates in a probabilistic fashion. In the general many-body setting the time-fluctuations of an observable \mathcal{A} are typically exponentially small in the system size. We consider here quasi-free Fermi systems where the Hamiltonian and observables are quadratic in the Fermi operators. We first prove
