    A DFT study on hydrogen diffusion across zinc surfaces at low coverage by Mihaela Buga, Teodora Murariu, Larisa-Milena Pioraş-Ţimbolmaş, Carmen Tripon, Luiza Buimaga-Iarinca, Cristian Morari

    Published 2025-08-01
    “…Molecular dynamics data allow us to estimate the vibrational density of states of adsorbed hydrogen and to calculate the diffusion coefficients. Vibrational data indicate that the vibrational motion parallel to the surface of the hydrogen atom has a similar frequency to that of the surface phonons, suggesting the role of vibrations in the diffusion process; moreover, we calculate the diffusion coefficient on top of a frozen surface and get values that are several orders of magnitude lower than those obtained in the presence of surface phonons, i.e. …”

    DMFFT: improving the generation quality of diffusion models using fast Fourier transform by Cuihong Yu, Cheng Han, Chao Zhang

    Published 2025-03-01
    “…Finally, it is decided to modify the feature extraction procedure of the CrossAttnUpBlock as the entrance to increase the overall diffusion generation quality. At the same time, employing the traditional Fourier transform method in image processing, the influence of frequency domain elements such as frequency, amplitude, and phase on image generation is investigated in the upsampling CrossAttnUpBlock of diffusion models, resulting in the method DMFFT, which can improve T2I or T2V quality without training or fine-tuning. …”

    Unleashing the Potential of Pre-Trained Diffusion Models for Generalizable Person Re-Identification by Jiachen Li, Xiaojin Gong

    Published 2025-01-01
    “…By incorporating ID classification probabilities generated from the Re-ID model with a set of learnable ID-wise prompts, the conditioning scheme injects dark knowledge that captures ID correlations to guide the diffusion process. Simultaneously, feedback from the diffusion model is back-propagated through the conditioning scheme to the Re-ID model, effectively improving the generalization capability of Re-ID features. …”

    Diffusion imaging changes in the treated tract following focused ultrasound thalamotomy for tremor by Erin L. Mazerolle, Robyn Warwaruk-Rogers, Paul Romo, Tejas Sankar, Sarah Scott, Conrad P. Rockel, Samuel Pichardo, Davide Martino, Zelma H.T. Kiss, G. Bruce Pike

    Published 2021-03-01
    “…At three months post-treatment, we additionally observed increased AD in the section between the lesion and cortex, and decreased FA in the section between the dentate nucleus and the decussation of the superior cerebellar peduncles. Diffusion changes at one day post-treatment may reflect local, acute effects such as inflammation and edema, as opposed to chronic degenerative processes such as axonal degeneration and myelin loss that would be expected at later time points. …”
