Apr 11, 2024 · In this work, we propose DiffLinker, an E (3)-equivariant three-dimensional conditional diffusion model for molecular linker design. Given a set of disconnected fragments, our model places...

Dec 17, 2024 · In this paper, we introduce the 3D Medical Diffusion (3D MedDiffusion) model for controllable, high-quality 3D medical image generation. 3D MedDiffusion incorporates a novel, highly efficient Patch-Volume Autoencoder that compresses medical images into latent space through patch-wise encoding and recovers back into image space through volume ...

Jan 2, 2025 · In this work, we propose MOFFUSION, a multi-modal conditional diffusion model that generates MOFs with careful attention to the three-dimensional (3D) shape of the pore structures (Fig. 1).

First, we need to train the three-dimensional VQ-GAN model. To do so in the BraTS dataset, you can run the following command: Note that you need to provide the path to the dataset (e.g. dataset.root_dir='/data/BraTS/BraTS 2020') to successfully run the command.

The diffusion tensor (DT) describes the diffusion of water molecules using a Gaussian model. Technically, it is proportional to the covariance matrix of a three-dimensional Gaussian distribution that models the displacements of the molecules.

Recent advancements in the ability to construct three-dimensional (3D) tissues and organoids from stem cells and biomaterials have not only opened abundant new research avenues in disease modeling and regenerative medicine but also have ignited ...

Aug 15, 2022 · Diffusion models are important in tissue engineering as they enable an understanding of gas, nutrient, and signaling molecule delivery to cells in cell cultures and tissue constructs. As three-dimensional (3D) tissue constructs become larger, more ...

Aug 1, 2023 · This work proposes a new three-dimensional inverse identification diffusion method based on extracting the diffusion parameters from each direction in hygromorph composites made of the shape memory epoxy and aligned long flax fibres.

Dec 9, 2024 · We formulate SBDD as a three-dimensional conditional generation problem and present DiffSBDD, an SE(3)-equivariant diffusion model that generates novel ligands conditioned on protein...

Jan 9, 2019 · This work is concerned with the investigation of a novel unconditionally positivity preserving finite difference (FD) scheme to be used for the solution of three dimensional Brusselator reaction-diffusion system.
