Two new two-dimensional covalent–organic frameworks are synthesized using a three-connected building block, showing ultrahigh iodine capture capacities of 5.625 g g<sup>−1</sup> and 4.820 on account physical–chemical adsorption.
Covalent-organic frameworks (COFs) as porous crystalline materials show promising potential applications. However, developing facile strategies for the construction of COFs directly from amorphous covalent organic polymers (COPs) is still a great challenge. To this end, we report novel approach easy preparation COPs through linkage replacement under different types reactions. Four with high crystallinity and porosity were constructed via substitution polyimide-linked to imine-linked well...
Two 2D COFs with high crystallinity and large specific surface area are constructed using a three-connected distorted building block. High porosity dense chemisorption sites effectively improved their iodine adsorption capacity.
Ground subsidence is a major concern for land use planning and engineering risk assessment. This paper explores detection by the persistent scatterer (PS) interferometric synthetic aperture radar (InSAR) technique using multitemporal high resolution spaceborne SAR images. We first describe mathematical models data reduction procedures of PS solution. The experiments are then carried out over Jinghai County in Tianjin (China) which has been sinking due to overuse groundwater. time series...
The semantic segmentation of point clouds is an important part the environment perception for robots. However, it difficult to directly adopt traditional 3-D convolution kernel extract features from raw because unstructured property clouds. In this article, a spherical interpolated operator proposed replace grid-shaped operator. addition, article analyzes defect cloud interpolation methods based on distance as weight and proposes self-learned distance-feature density by combining feature...
To explore the small-world properties of brain functional networks in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) to aid diagnosis.A total 29 OSAHS and 26 matched healthy volunteers were scanned blood oxygen level-dependent magnetic resonance imaging (BOLD-fMRI) separately, whole was divided into 90 districts via automated anatomical labeling. The matrix Z then built through a Fisher transformation. Two-sample t tests applied evaluate changes compared control group....

Summary of main observation and conclusion A highly efficient catalytic system for the N ‐arylation reactions (hetero)aryl chlorides nitrogen heterocycles with a copper(I) complex containing 1,10‐phenanthroline analogue ‐heterocyclic carbene (NHC) has been reported. The was characterized by 1 H NMR 13 C spectroscopy elemental analysis, its structure determined single‐crystal X‐ray diffraction. NHC‐copper(I) employed as pre‐catalyst Ullmann type various azoles. variety hindered functionalized...
Obstructive sleep apnea-hypopnea syndrome (OSAHS) is normally linked to cognitive and functional dysfunctions. In this study, we explored the resting-state connectivity (rsFC) in default mode network (DMN) show mechanism of neurophysiology patients with OSAHS. Resting-state structural Magnetic Resonance Imaging (fMRI) data were obtained from sixteen male moderate-to- severe untreated OSAHS 15 matched healthy control subjects. The rsFC DMN was analyzed between controls by CONN software....
The Ms8.0 Wenchuan earthquake occurred on May 12, 2008 in County, Sichuan Province, China. devastating event caused a significant surface rupture and deformation large geographical area. This study intends to investigate the co-seismic deformations due main shock by integrating observations from interferometric synthetic aperture radar (InSAR) global positioning system (GPS). InSAR measurements an area of more than 83,000 km<sup>2</sup> are extracted 46 SAR images that were acquired along 6...
Few-shot recognition aims to train a classification model with only few labeled examples of pre-defined concepts, where annotation can be costly in downstream task. In another related research area, zero-shot recognition, which assumes no access any downstream-task data, has been greatly advanced by using pretrained Vision-Language Models (VLMs). this retrieval-augmented learning (RAL) effectively boosts accuracy retrieving and from external data relevant concepts. Motivated these...
This paper introduces a 3D point cloud sequence learning model based on inconsistent spatio-temporal propagation for LiDAR odometry, termed DSLO. It consists of pyramid structure with spatial information reuse strategy, sequential pose initialization module, gated hierarchical refinement and temporal feature module. First, features are encoded using pyramid, reused in successive estimations to reduce computational overhead. Second, method is introduced, leveraging the high-frequency sampling...
With the development of urban construction, excavation area a foundation pit becomes larger, depth deeper, and surrounding environment more complex, which requires higher risk control. As new construction method,the pit-divided method prevalent in pit.
