We report on the cosmic ray mass composition measured by the Telescope Array Low-energy Extension (TALE) hybrid detector. The TALE detector began operations in 2017 with 10 high-elevation fluorescence telescopes and a surface detector (SD) array of 80 scintillation counters, including 40 with 400 m spacing and 40 with 600 m spacing. In 2023, we constructed a new array made up of 50 SDs with a spacing of 100 m to lower the energy threshold of hybrid mode down to PeV range for the investigation of the cosmic ray mass composition around knee structure in the spectrum. Here we will present an estimate of the performance of the hybrid mode which is a combination of the new SD array and TALE-FD using a Monte Carlo simulation, and report the first preliminary results of the mass composition measurement using the new hybrid detector. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0) All rights for text and data mining, AI training, and similar technologies for commercial purposes, are reserved.

Enhanced High-Temperature Energy Storage Properties of BOPP Capacitor Films by Coating Heterostructural Ceramics Layers

Biaxially oriented polypropylene (BOPP), the dielectric material of choice for polymer film capacitors, is widely used in advanced electronic devices and power grids, among other applications. However, the nonlinear growth of the conduction loss at high temperatures leads to a rapid deterioration of its energy storage performance, which seriously hinders the development trend of miniaturisation and high integration of power systems. In this study, inorganic nanolayers with heterogeneous structure were grown on the surface of BOPP films by magnetron sputtering using high dielectric constant BaZrTiO3 and wide bandgap Al2O3 ceramic targets. Experimental and theoretical analyses show that the use of wide bandgap Al2O3 as the heterojunction outer layer can effectively impede carrier injection and transport, leading to a significant reduction in the leakage current density of the composite film, effectively enhancing the high temperature energy storage performance of the composite films. The synergistic enhancement of the inorganic heterojunction structure on the dielectric properties and insulating strength of the polymer film is attributed to the ability of the Al2O3/BaZrTiO3/BOPP/BaZrTiO3/Al2O3 (O-B-P-B-O) composite films to exhibit a discharge energy density of 2.49 J/cm3 and a charge/discharge efficiency of 77.6% at 125°C and 500 MV/m. © 2025 The Author(s).

A post-coding scheme for peak-to-average power ratio reduction in intensity modulated optical OFDM systems

引用

Optoelectronics Letters 2014年第4期10卷 295-298页

作者：陈芳妮王中鹏 School of Information and Electronic Engineering Zhejiang University of Science and Technology State Key Laboratory of Millimeter Waves Southeast University

An efficient post-coding strategy is proposed in this letter to reduce the peak-to-average power ratio(PAPR) of orthogonal frequency division multiplexing(OFDM) signals for optical intensity modulated direct detection(IM/DD) systems. The post-coding scheme based on discrete cosine transform(DCT) is employed after the inverse fast Fourier transform(IFFT) in the transmitter to reduce the PAPR of OFDM signals. This method is different from the conventional pre-coding scheme which is employed before IFFT operation. Numerical simulations demonstrate that the new DCT post-coding strategy can significantly reduce the PAPR than the conventional pre-coding scheme. Meantime, the bit error rate(BER) performance of the proposed post-coding system can be improved compared with the conventional pre-coding scheme.

As a nonlinear and time-varying complex dynamic system, wastewater treatment process(WWTP) is difficult to be controlled. In this paper, to control the dissolved oxygen(DO) concentration in a WWTP, a growing and pruning recurrent fuzzy neural network(GPRFNN)-based control system is proposed which contains RFNN controllers and RFNN identifier. The identifier is used to model the WWTP with an adaptive algorithm to afford model information for the controllers, while the controllers are designed to adjust the control variables to make the WWTP run smoothly. Furthermore, the structure of the RFNN is self-organized to keep the output steady in structural adjustment phase, which is also theoretically proved. Finally, the control performance of the proposed system is shown by simulation results.

Energy-Efficient Computation Offloading and Resource Allocation in Fog Computing for Internet of Everything

With the dawning of the Internet of Everything(IoE) era, more and more novel applications are being deployed. However, resource constrained devices cannot fulfill the resource-requirements of these applications. This paper investigates the computation offloading problem of the coexistence and synergy between fog computing and cloud computing in IoE by jointly optimizing the offloading decisions, the allocation of computation resource and transmit power. Specifically, we propose an energy-efficient computation offloading and resource allocation(ECORA) scheme to minimize the system cost. The simulation results verify the proposed scheme can effectively decrease the system cost by up to 50% compared with the existing schemes, especially for the scenario that the computation resource of fog computing is relatively small or the number of devices increases.

The rapid development of Artificial Intelligence technology has led to the victory of AlphaGo, making people see the hope of intelligent military command decision support system. However, battlefield is quite complex, while chessboard is significantly abstracted. It is impossible to copy its method directly, as machine learning from observations directly to orders, or from orders directly to results is too difficult. This paper attempts to decompose the problem of intelligent command decision support system into more specific problems, and analyze which type of AI methods suit which problems, through the local technology breakthrough to achieve the overall level of intelligence to enhance, with a certain guiding significance to development of intelligent command decision support system. © 2018 IEEE.

We demonstrate a simple scheme to perform all-optical clock recovery from the input nonreturn-to-zero(NRZ)and nonreturn-to-zero differential phase shifted keying(NRZ-DPSK)data,which are avoided using any preprocessing measures.A multi-quantum-well Fabry-Pérot semiconductor optical amplifier plays the dual role of the data format converter and the clock recovery *** this scheme,a stable and low jitter 35.80-GHz optical clock pulse sequence is directly extracted out from the input NRZ or NRZ-DPSK *** scheme has some distinct advantages such as simple device fabrication,transparence to data format,multiwavelength operation,free preprocessing and convenient *** powerful adaptability of this scheme is very important for next-generation optical networks,in which there exist various modulation formats and the used devices are required to be transparent to data formats.
