Abstract The biofabrication of three-dimensional (3D) tissues that recapitulate organ-specific architecture and function would benefit from temporal spatial control cell-cell interactions. Bioprinting, while potentially capable achieving such control, is poorly suited to organoids with conserved cytoarchitectures are susceptible plastic deformation. Here, we develop a platform, termed Spatially Patterned Organoid Transfer (SPOT), consisting an iron-oxide nanoparticle laden hydrogel...
Recently, moderate-resolution remote sensing images have been widely used in extracting coastal aquaculture areas that are usually to obtain marine fishery resources. However, images, the destroyed by storm-tide hard be observed. In order get information of quickly and accurately, help scientific management planning resources meet needs disaster emergency response, it is imperative extract based on high-resolution images. as spatial resolution increases, there many disadvantages traditional...
Abstract The underground building environment plays an increasingly important role in the construction of modern cities. To deal with possible fires, collapses, and so on, space, it is a general trend to use rescue robots replace humans. This paper proposes dual‐robot system solution for search environment. speed up search, two focus on different tasks. However, environmental perception information location them are shared. primary robot used quickly explore wide range, identify objects,...
Change detection of cultivated land parcels is critical for achieving refined management farmland. However, existing change methods based on high-resolution remote sensing imagery focus primarily cultivation type changes, neglecting the importance detecting parcel pattern changes. To address issue diverse types changes in parcels, this study constructs an automated workflow framework detection, unsupervised segmentation method SAM (Segment Anything Model). By performing spatial connection...
The material test results show that the chemical composition, size, grain size and hardness of fractured coiled tubing meet standard requirements, no abnormal are found. There mechanical trauma in fracture suspected improper operation on both sides position, which causes tube body damage by stacking clamping blocks, will cause deformation tubing. thinning wall thickness increase reduce strength tubing, is main reason for
The development of high spatial resolution satellite imaging has enabled the acquisition mariculture area information. This data could play an important role in investigations, ocean disaster evaluations, and coastal management. Because chlorophyll is concentrated widely distributed raft culture (a major kind mariculture), Normalized Difference Vegetation Index (NDVI) can be used for extraction. However, extensive easily confused with heterogeneous water background. results unsatisfactory...
A systematic wear model of the cylindrical grinding process with an alumina abrasive belt from perspective single grain sliding was established in this study. The consists three parts: a cutting force derived by applying stress integration method, height analysis based on rate alumina, and mileage prediction multiple grains Gaussian distributed protrusion heights. Cutting force, full-size verification experiments were conducted. results indicated that reasonable agreement experimental...
Accurate cultivated land parcel data are an essential analytical unit for further agricultural monitoring, yield estimation, and precision agriculture management. However, the high degree of landscape fragmentation irregular shapes parcels, influenced by topography human activities, limit effectiveness extraction. The visual semantic segmentation model based on Segment Anything Model (SAM) provides opportunities extracting multi-form parcels from high-resolution images; however, performance...
In this paper, a novel high temperature strain sensor based on polyimide-coated fiber Bragg grating (FBG) and rhombus metal structure is presented experimentally demonstrated. By heating low softening point glass via micro torch, the FBG could be fixed into structure. Consequently, when stretched compressed, respectively, then will subjected to reverse state. Moreover, sensitivity controllable enhanced by adjusting dimension of appropriately. The experiment was carried out using an...
Information, especially spatial distribution data, related to coastal raft aquaculture is critical the sustainable development of marine resources and environmental protection. Commercial high resolution satellite imagery can accurately locate aquaculture. However, this type analysis using expensive requires a large number images. In contrast, medium imagery, such as Landsat 8 images, are available at no cost, cover areas with less data volume, provide acceptable results. Therefore, we used...
Rail grinding has been widely recognized as an essential measure in routine maintenance of railway network the world. Compared with other technologies, emerging abrasive belt process for direct rail rather than limited polishing finish shown convincing potential to improve metal removal rate and surface quality. However, influencing mechanism rubber wheel on contact pressure corrugated rails is yet unknown. This paper develops a model obtain boundary curve stress distribution zone between...
Data security technology is of great significance for the effective use high-resolution remote sensing (HRRS) images in GIS field. Integrity authentication an important to ensure HRRS images. Traditional technologies perform binary level data and cannot meet requirements images, while perceptual hashing can achieve content-based authentication. Compared with traditional algorithms, existing edge-feature-based hash algorithms have already achieved high tampering accuracy However, because...
