Manually annotating anatomical landmarks in medical images requires experienced clinicians and is a labor-intensive process. However, recent AI-assisted methods for landmark detection often rely on the training and test data originating from the same domain. This work introduces a novel unsupervised domain adaptation (UDA) framework aimed at anatomical landmark detection from a medical image, designed to bridge the gap between a source domain with labels and an unlabeled target domain. Specifically, we have developed a new Domain-Adversarial Network that incorporates skip connections to transfer and fuse high-resolution feature maps. Additionally, we proposed Dynamic Gaussian Learning, which allows the model to escape from local error regions. We carry out experiments on landmark detection for both head and chest, and the results demonstrate that our method achieves state-of-the-art performances in each experiment. © 2025 IEEE.

Metal halide perovskite nanocrystals have attracted great attention of researchers due to their unique optoelectronic properties such as high photoluminescence quantum yield (PLQY), narrow full width at half-maximum (FWHM), long exciton diffusion length and high carrier mobility, which have been widely used in diverse fields including solar cells, photodetectors, light-emitting diodes, and lasers. Very recently, metal halide perovskites have emerged as a new class of materials in photocatalysis due to their promising photocatalytic performance. In this review, we summarize the recent advances on synthesis, modification and functionalization, with a specific focus on the photocatalytic application of metal halide perovskite nanocrystals. Finally, a brief outlook is proposed to point out the challenges in this emerging area. The goal of this view is to introduce the photocatalytic application of the metal halide perovskites and motivate researchers from different fields to explore more potentials in catalysis.

In situ formation of highly dispersed LaH3 and Mg2Ni derived from 3DOM LaNiO3 for the hydrogen storage kinetics enhancement of MgH2

Journal of Alloys and Compounds 2025年 1032卷

(3DOM) LaNiO3 catalysts were successfully synthesized and significantly improved the hydrogen storage kinetics of MgH2. MgH2-5 wt% 3DOM LaNiO3 can rapidly absorb 5.91 wt% H2 at 175 °C within 500 s and desorb 6.37 wt% H2 within 500 s at 300 °C, its hydrogen absorption and desorption rates are 10 and 11 times higher than MgH2-5 wt% Nano LaNiO3, respectively. This remarkable enhancement is primarily due to its unique 3DOM structure and the synergistic effect of highly dispersed LaH3 and Mg2Ni/Mg2NiH4 formed in situ during the ball milling and first de/re-hydrogenation process. 3DOM structure catalysts are fragile which can make the catalyst distribution more uniform during ball milling process, giving rise to the significantly improved catalytic activity. The theoretical calculation results show that Mg2Ni/LaH3 heterostructure can greatly reduce the hydrogen adsorption energy to −0.768 eV and the heterogeneous interface induces the charge redistribution between Mg2Ni and LaH3, resulting in a small amount of negative charge accumulating on the surface of Mg2Ni. Moreover, highly dispersed LaH3 and Mg2Ni/Mg2NiH4 in the MgH2 matrix create a multiphase interface, which can provide more active sites and a variety of pathways for hydrogen diffusion. Above reasons contribute to the excellent synergistic catalytic performance of in situ formed LaH3 and Mg2Ni/Mg2NiH4 on MgH2. These discoveries hold scientific value for the design and preparation of highly active catalysts using 3DOM materials for hydrogen storage in light-metal hydrides, especially in MgH2. © 2025 Elsevier B.V.

Shape memory alloy (SMA) has been used in robotic actuators due to its advantages, such as shape memory effect, high damping capacity, and temperature sensitivity. However, its practical application has been limited by the low frequency of heating-cooling cycles and small deformation caused by heat dissipation. To address this issue, this paper presents an insect-scale multi-segment worm robot actuated by a biomimetic soft compound muscle composed of Shape Memory Alloy Wire (SMAW), Polydimethylsiloxane (PDMS), and Acrylonitrile Butadiene Styrene (ABS). The robot’s design includes multiple SMAWs in parallel and an ABS fiber rib with a scaffold structure embedded into the PDMS matrix, allowing for the conversion of the linear small deformations of the SMAW into large bending-expanding motions of the biomimetic muscle. The robot consists of two independently and alternately excited segments that form worm gaits. The soft muscle with multiple thin SMAWs and the multi-segment design enable better heat dissipation, which improves the actuation frequency and the robotic locomotion ability. Experimental results show that the bimimetic robot actuated by SMAWs can reach a speed of 24.33mm/s for a 5Hz PWM signal and 7.33mm/s with a load of three times its weight, outperforming robots of the same scale size and SMA actuation. These results demonstrate that the multi-segment structure with multiple thin SMAWs of the biomimetic robot provides a feasible solution for applying SMA to robotic higher frequency actuation.

An efficient heterogeneous catalytic system for the [4 + 2] annulation reactions between tertiary anilines and tetrahydrofuran has been developed based on CuCoFe layered double oxide in the study. Cu+ species was believed to play the crucial role in the catalytic transformation, and synergistic effect between Cu and CoFe species was observed in the reaction. Various tertiary anilines could be tolerated by the present catalytic system. A series of control experiments were conducted to determine the reaction intermediates. A distinctive reaction mechanism has been described for the annulation reaction based on these results and kinetic isotopic effects experiments. © 2024 Elsevier B.V.
