An Iris Image Super-Resolution Model Based on Swin Transformer and Generative Adversarial Network

Algorithms
The process of iris recognition can result in a decline in recognition performance when the resolution of the iris images is insufficient. In this study, a super-resolution model for iris images, namely SwinGIris, which combines the Swin Transformer and ...

A Novel Pure Pursuit Algorithm for Autonomous Vehicles Based on Salp Swarm Algorithm and Velocity Controller

IEEE Access, 2020
Pure pursuit algorithm is one of the most effective ways of path tracking in autonomous vehicles. Nevertheless, the tracking accuracy of the existing pure pursuit algorithm is limited by the look-ahead distance.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

DANet: Temporal Action Localization with Double Attention

Applied Sciences, 2023
Temporal action localization (TAL) aims to predict action instance categories in videos and identify their start and end times. However, existing Transformer-based backbones focus only on global or local features, resulting in the loss of information. In

The two-mass contributions to the three-loop massive operator matrix elements $${\widetilde{A}}_{Qg}^{(3)}$$ and $${\Delta \widetilde{A}}_{Qg}^{(3)}$$

Journal of High Energy Physics
We calculate the two-mass three-loop contributions to the unpolarized and polarized massive operator matrix elements $${\widetilde{A}}_{Qg}^{(3)}$$ and $${\Delta \widetilde{A}}_{Qg}^{(3)}$$ in x-space for a general mass ratio by using a semi-analytic ...
