Unpacking the Fragmentation–Ecology Nexus: Spatial Heterogeneity, Nonlinear Responses, and Associated Ecological Factors Across Urban Agglomerations in the Yellow River Basin

Meiling Zhou, Meiling Gao, Zhenhong Li, Xinxin Fu et autres

Ecological quality and landscape fragmentation are closely linked in rapidly urbanizing regions, yet their relationship across different urbanization contexts remains insufficiently understood. This study examined the spatiotemporal dynamics and coupling between the Remote Sensing Ecological Index (RSEI) and Landscape Fragmentation Index (LFI) …

Incorporation of Graphdiyne‐Based sp‐Carbon Into the First Coordination Sphere of a Metal Complex for the Electrocatalysis of Nitric Oxide to Ammonia

Jiahao Ma, Jieyu Liu, Changhong Wang, Chuanqi Cheng et autres

ABSTRACT Although metal‒carbon bonds are prevalent in organometallics, integrating carbon donors alongside nitrogen, oxygen, and sulfur heteroatoms into the first coordination sphere of metal complexes poses a considerable challenge. Here, graphdiyne‐based sp‐carbon atoms are incorporated into the first coordination sphere of the …

In situ Discovery of Immune Repertoire Reveals Antitumor Immunity and Therapeutic Antibodies

Haorui Zhang, Peiyu Wang, Yahui Zhao, Lukai Yang et autres

ABSTRACT Spatial transcriptomics offers a glimpse into the immunology of tissues. However, limitations in spatial transcriptomics preclude the detection of highly diverse, low-abundance, and previously unknown sequences, including immune repertoires and microbiota. Here, we introduce Archimap, a spatial transcriptomic platform that simultaneously …

Integrating Histology with Spatial Molecular Programs Using a Multimodal Foundation Model

Zongxu Zhang, Bowen Qin, Yu Zhao, Zekun Qi et autres

Abstract Histopathological assessment remains central to cancer diagnosis and stratification, yet its mechanistic interpretation remains limited without molecular context. To address this, we developed SQUALL, a multimodal foundation model integrating histology with spatial molecular programs. For pretraining, we assembled histMol , a …

SOAF: Scene Occlusion-aware Neural Acoustic Field

Huiyu Gao, Jiahao Ma, David Ahmedt‐Aristizabal, Chuong Nguyen et autres

This paper tackles the problem of novel view acoustic synthesis along an arbitrary trajectory in an indoor scene, given the audio-video recordings from other known trajectories of the scene. Existing methods often overlook the effect of room geometry, particularly wall occlusions on …

Orbit-specific tropospheric effects on Sentinel-1A/B interferometric synthetic aperture radar observations: insights for deformation analysis and future mission design

Jie Li, Chen Yu, Xiaoning Hu, Zhenhong Li et autres

Interferometric Synthetic Aperture Radar (InSAR) is a powerful tool for mapping surface movements, but tropospheric delays complicate deformation interpretation. Tropospheric errors are influenced by various spatiotemporal factors, including water vapor, temperature and pressure and all these factors are related to satellite orbit …

Nanozymes for ATP/cAMP balance restoration and ROS scavenging in inflammatory dermatosis treatment and recurrence prevention

Xiaolei Su, Jiahao Ma, Zhenhua Liu, YaoYao Li et autres

Inflammatory dermatoses like psoriasis and atopic dermatitis are prevalent autoimmune disorders whose management is challenged not only by inflammatory lesions but, more significantly, by persistent pruritus and frequent relapse following treatment discontinuation. The pathogenic progression of these dermatoses is critically influenced by …

Coordination Engineering of Iron‐Polyphthalocyanines with H‐Substituted Graphdiyne for the Tandem Catalysis of Nitrate to Hydroxylamine

Kexin Liu, Jiahao Ma, Z.Y. Ma, Chuanqi Cheng et autres

Abstract Hydroxylamine (NH 2 OH) can be generated by controlling the nitrate electroreduction process, the key of which lies in the hydrogenation of *NO. In this study, hydrogen‐substituted graphdiyne (HsGDY) is developed to engineer the growth of iron‐polyphthalocyanine (FePPc) with four Fe‐N …
