Radioastron probing the fine structure of the flaring H2O maser in star-forming region G25.65+1.05
The paper describes a Space-VLBI observation of the 22 GHz H2O masers in the massive star-forming region G25.65+1.05, using the 10-m space antenna of Radioastron together with the ground-based VLBA array. Two observing epochs at the pre-flare and post-flare state of the maser source are presented. Leveraging the exceptional angular resolution provided by space-ground baselines along with the broad UV coverage from VLBA baselines, we gained a detailed perspective on the area associated with the …

Passive Multi-Target Visible Light Positioning Based on Multi-Camera Joint Optimization
Camera-based visible light positioning (VLP) has emerged as a promising indoor positioning technique. However, the need for dedicated LED infrastructure and on-target cameras in existing algorithms limits their scalability and increases deployment costs. To address these limitations, this letter proposes a passive VLP algorithm based on Multi-Camera Joint Optimization (MCJO). In the considered system, multiple pre-calibrated cameras mounted on the ceiling continuously capture images of position…

Scintillation Properties of PSR B1133+16 Measured with Very Long Baseline Interferometry
The scintillation of pulsars reveals small-scale structure of the interstellar medium. A powerful technique for characterizing the scintillating structures (screens) combines analysis of scintillation arcs and very long baseline interferometry (VLBI). We present the results of a VLBI analysis of the scintillation arcs of PSR B1133+16 from simultaneous observations with Arecibo, VLA, Jodrell Bank, Effelsberg, and Westerbork. Three arcs appear in the data set, all of which appear consistent…

MTCNet: Motion and Topology Consistency Guided Learning for Mitral Valve Segmentationin 4D Ultrasound
Mitral regurgitation is one of the most prevalent cardiac disorders. Four-dimensional (4D) ultrasound has emerged as the primary imaging modality for assessing dynamic valvular morphology. However, 4D mitral valve (MV) analysis remains challenging due to limited phase annotations, severe motion artifacts, and poor imaging quality. Yet, the absence of inter-phase dependency in existing methods hinders 4D MV analysis. To bridge this gap, we propose a Motion-Topology guided consistency network (MT…

Exploring Transferability of Multimodal Adversarial Samples for Vision-Language Pre-training Models with Contrastive Learning
The integration of visual and textual data in Vision-Language Pre-training (VLP) models is crucial for enhancing vision-language understanding. However, the adversarial robustness of these models, especially in the alignment of image-text features, has not yet been sufficiently explored. In this paper, we introduce a novel gradient-based multimodal adversarial attack method, underpinned by contrastive learning, to improve the transferability of multimodal adversarial samples in VLP models. This…

Are Crypto Ecosystems (De)centralizing? A Framework for Longitudinal Analysis
Blockchain technology relies on decentralization to resist faults and attacks while operating without trusted intermediaries. Although industry experts have touted decentralization as central to their promise and disruptive potential, it is still unclear whether the crypto ecosystems built around blockchains are becoming more or less decentralized over time. As crypto plays an increasing role in facilitating economic transactions and peer-to-peer interactions, measuring their decentralization b…
