Traditional online map tiles, widely used on the Internet such as Google Map and Baidu Map, are rendered from vector data. Timely updating tiles data, of which generating is time-consuming, a difficult mission. It shortcut to generate in time remote sensing images, can be acquired timely without However, this mission challenging or even impossible. Inspired by image-to-image translation (img2img) techniques based generative adversarial networks (GAN), we proposed semi-supervised Generation...

Abstract Learning rate scheduling (LRS) is a critical factor influencing the performance of neural networks by accelerating convergence learning algorithms and enhancing generalization capabilities. The escalating computational demands in artificial intelligence (AI) necessitate advanced hardware solutions capable supporting network training with LRS. This not only requires linear symmetric analog programming capabilities but also precise adjustment channel conductance to achieve tunable...

Screen-camera communication using dynamic barcode streaming has emerged as a convenient and secure method for short-range, impromptu device-to-device communication. Conventional systems adopt rule-based approach to recognize the color stream in receiver, which is empirical, inflexible, lacks self-adaptiveness. In this paper, we propose novel solution framework recognition basing on machine learning techniques. By including number of training frames into build classification model, proposed...

Considering the success of generative adversarial networks (GANs) for image-to-image translation, researchers have attempted to translate remote sensing images (RSIs) maps (rs2map) through GAN cartography. However, these studies involved limited scales, which hinders multi-scale map creation. By extending their method, RSIs can be trivially translated (multi-scale rs2map translation) scale-wise models trained certain scales (parallel strategy). this strategy has two theoretical limitations....

Abstract A new ring‐fused streptovaricin analogue, named ansavaricin J, was unprecedently isolated from the culture of genetically modified strains ΔstvP5 which derived Streptomyces spectabilis CCTCC M2017417. Its structure elucidated via comprehensive spectroscopic analyses, including 1D‐ and 2D‐NMR tests, HR‐ESI‐MS data analysis. Notably, J E represent only two reported examples heterocyclic streptovaricins thus far, however, it showed insignificant antibacterial activities against...

Along with the development of earth observation technology, large amounts geospatial information are accessible. There also a lot data and services which shared on Internet. However they vary in formats stored at various organizations leading to problems discovery, interoperability usability. The Open Geospatial Consortium (OGC) has developed standard service called catalogue order overcome this problem. goal is support wide range users discovering relevant geographic from heterogeneous...

Recently, induced by incorporating the ubiquitous data collected AI application, there are more and demand for transferring to cloud servers due restriction of computing resources devices. To transfer image efficiently, neural network (NN) codec can be a wise choice, which result in higher ratio compression with similar quality compared conventional methods. However, when NN is employed communication system, it likely that disturbed channel distortions. In this paper, we innovatively propose...
