Non-local effects have the potential to radically move forward quantum enhanced imaging provide an advantage over classical not only in laboratory environments but practical implementation. In this work, we demonstrate a 43dB higher signal-to-noise ratio (SNR) using LiDAR based on time-frequency entanglement compared with phase-insensitive system. Our system can tolerate more than 3 orders of magnitude noise single-photon counting systems before detector saturation dead time 25ns. To achieve...

Lensless imaging based on multi-wavelength phase retrieval becomes a promising technology widely used as it has simple acquisition, miniaturized size and low-cost setup. However, measuring the sample-to-sensor distance with high accuracy, which is key for high-resolution reconstruction, still challenge. In this work, we propose criterion to realize autofocusing modulation, i.e., achieving much higher accuracy in determining distance, compared conventional methods. Three beams different...

Quantifying woody vegetation cover is essential for understanding evolution and formulating land use management policies. However, most attention has focused on the retrieval of forest attributes, it imperative to enhance capability monitor vegetation. This study proposed an adaptive stacking regressor with a self-iterative optimization module improve quantification fractional cover. The model was trained using synthetic mixing techniques 2021 Landsat composite estimate proportion in Shaanxi...

Traditional brain-computer systems are complex and expensive, emotion classification algorithms lack repre-sentations of the intrinsic relationships between different channels electroencephalogram (EEG) signals. There is still room for improvement in accuracy. To lower research barrier EEG harness rich information embedded multi-channel EEG, we propose implement a simple user-friendly system classifying four emotions: happiness, sorrow, sadness, tranquility. This utilizes fusion...

It is by means of Lyapunov method that stochastic ordinary differential equations and functional have been studied intensively. However, for reaction diffusion equations, this useful technique seems to find no way out on account the empty its own Ito's formula. To get over difficulty, we will regard integral considered trajectory with respect spatial variables as solution corresponding via employing formula under operator instead directly applying functions in case aim at establishing theory...

Under the guidance of Xi Jinping's thought on rule law, this paper takes "Youth Law Popularization Volunteers' Grassroots Tour Rule Culture" as a carrier to promote law in youth volunteer popularization activities. Thus, theory and practice socialist with Chinese characteristics has gained much popularity among residents, seen improvement authority Constitution more people respecting, learning, observing, using social governance. All these play an important role comprehensively promoting...

With the rapid development of distributed photovoltaic (PV), prediction installed scale and generation power PV plays an important role in studying impact on grid. The paper proposes a method for forecasting capacity which takes into account changes return investment (ROI) PV. Case Study Shanghai as example estimates its installation potential forecasts next few years.
