Abstract Although various photonic devices inspired by natural materials have been developed, there is no research focusing on multibands adaptability, which not conducive to the advancement of science. Herein, moth eye surface model, state‐of‐the‐art hierarchical metamaterials (MMs) used as tunable in multispectral electromagnetic‐waves (EMWs) frequency range, from microwave ultraviolet (UV), are designed and prepared. Experimentally, robust broad bandwidth absorption greater than 90%...
With the development of earth observation technologies, acquired remote sensing images are increasing dramatically, and a new era big data in is coming. How to effectively mine these massive volumes challenges. Deep learning provides approach for analyzing data. As one deep models, convolutional neural networks (CNNs) can directly extract features from amounts imagery good at exploiting semantic CNNs have achieved remarkable success computer vision. In recent years, quite few researchers...
The Multipath TCP (MPTCP) protocol has been standardized by the IETF as an extension of conventional TCP, which enables multi-homed devices to establish multiple paths for simultaneous data transmission. Congestion control is a fundamental mechanism design and implementation MPTCP. Due diverse QoS characteristics heterogeneous links, existing multipath congestion mechanisms suffer from number performance problems such bufferbloat, suboptimal bandwidth usage, etc. In this paper, we propose...
The Multipath TCP (MPTCP) protocol, featured by its ability of capacity aggregation across multiple links and connectivity maintenance against single-path failure, has been attracting increasing attention from the industry academy. packet scheduling is a unique fundamental mechanism for design implementation MPTCP, which responsible distributing traffic over subflows. existing multipath schedulers are facing challenges network heterogeneities, comprehensive QoS goals, dynamic environments,...
With the rapid development of high-speed communication and artificial intelligence technologies, human perception real-world scenes is no longer limited to use small Field View (FoV) low-dimensional scene detection devices. Panoramic imaging emerges as next generation innovative intelligent instruments for environmental measurement. However, while satisfying need large-FoV photographic imaging, panoramic are expected have high resolution, blind area, miniaturization, multidimensional...

High-quality panoramic images with a Field of View (FoV) 360° are essential for contemporary computer vision tasks. However, conventional imaging systems come sophisticated lens designs and heavy optical components. This disqualifies their usage in many mobile wearable applications where thin portable, minimalist desired. In this paper, we propose Panoramic Computational Imaging Engine (PCIE) to achieve high-quality imaging. With less than three spherical lenses, Minimalist Prototype (MPIP)...
Acid rain can significantly undermine the structural integrity and seismic resilience of concrete structures, posing substantial risks catastrophic failures jeopardizing safety.

As the main energy source for thermal power generation, coal generates a large amount of NOx during its incineration in boilers, and excessive emissions can cause serious pollution to air environment. Selective catalytic reduction denitrification (SCR) selects optimal ammonia be injected based on measurement concentration by automatic flue gas monitoring system. Since system has delay measurement, it cannot accurately reflect real-time changes at SCR inlet when unit load fluctuates, leading...
