title: The data of the article "Combining Deep Reinforcement Learning with Heuristics for Solving the Traveling Salesman Problem"

description: We have developed a new framework for learning improvement heuristics, which automatically discovers better improvement policies for heuristics to iteratively solve the TSP. Our framework proposes a novel approach (named RL-SA), which combines deep RL with SA algorithm, to improve 2-opt heuristic algorithm’s performance in learning a pairwise selected policy of next promising solutions. The novelty of the RL-SA approach also lies in that it leverages the Whale Optimization Algorithm (WOA) to generate an initial solution for better sampling efficiency, and that it adopts the Gaussian perturbation strategy for perturbing the state to tackle the sparse reward problem of the RL algorithm. Our program achieved excellent performance in solving the Traveling Salesman Problem.

title: Data of High-Performance Self-Powered PEC Photodetectors Based on 2D BiVO4/MXene Schottky Junction

description: As an emerging field, self-powered photoelectrochemical (PEC) photodetectors have gradually attracted extensive attention thanks to the unique working characteristics of low preparation cost, strong tunability of device performance, and environmental friendliness. However, short absorption wavelength range, low efficiency of visible light utilization, and low responsivity remain challenges for performance improvements. Here, the PEC photodetectors based on the 2D BiVO4/MXene Schottky junction structure, which shows excellent performance with high photocurrent density (≈3.90 mA cm−2 at 0 VSCE under AM 1.5 G, 150 mW cm−2), good responsivity (790.2 mA W−1 under 447 nm), fast response time (tr/tf = 8/14 ms), and long-term stability (keep 17 000 s and 22 000 cycles) are fabricated. These can be attributed to the built-in electric field at the BiVO4/MXene Schottky junction interface, which accelerates the transfer of photogenerated electrons and holes, and inhibits interfacial charge recombination. Additionally, the MXene nanosheets improve the absorption of visible-light-induced photons on the valence band of BiVO4. These excellent properties show that this work provides a scientific experimental reference for the further development of PEC photodetectors.

title: Comparative Study on the Structural Properties and Electrochemical Performance of Xylan-derived Char Catalyzed by Na2CO3 at Various Concentrations
title: 不同浓度Na₂CO₃催化的木聚糖衍生炭的结构与电化学性能研究

description: This study investigated the catalytic effect of Na2CO3 on the structural properties of xylan char, and tested its electrochemical performance as an anode material for sodium-ion batteries. Characterization using X-ray microscopy and scanning electron microscopy demonstrated that the morphological structure of xylan char was altered following Na2CO3 catalysis. Increasing the Na2CO3/xylan ratio resulted in a slenderization of the triangular prism shape of the char skeleton and a reduction in porosity. X-ray diffraction analysis showed that Na2CO3 promoted the growth of the (004) crystal plane of graphite during xylan pyrolysis, while inhibiting the formation of the (100/101) crystal planes. Raman spectroscopy analysis indicated that the presence of Na2CO3 had changed the graphitization degree of xylan char. Electrochemical tests further showed that char prepared with a Na2CO3/xylan mass ratio of 1:1 exhibited the highest sodium storage capacity. These findings suggest that carbon materials derived from xylan hold promise for future applications in energy storage devices.

title: Abstract Dataset of Tibetan Text Extracted Based on Greedy Rule
title: 基于贪心规则抽取的藏文文本摘要数据集

description: Among the existing research on text abstracts, the research on Tibetan text abstracts is still in its infancy, especially in the construction of data sets. Therefore, we constructed a dataset specifically for Tibetan text abstracts to fill this research gap. In our approach to data set production, we adopted an innovative greedy strategy. First, the Tibetan text is processed by clauses, then the Rough value of each sentence and title is calculated, and the sentence with the highest Rough value is selected. Then, the sentence is selected from the remaining sentence and the selected sentence is spliced, the Rough value is calculated again, and the sentence with the highest Rough value is selected for splicing. This process is repeated until three sentences are selected as summaries. The design of this method aims to make the generated abstracts reflect the main information of the text more accurately and comprehensively through the process of gradual screening and optimization, so as to improve the quality and effectiveness of Tibetan text abstracts. Through this research, we hope to provide strong data support for the study of Tibetan text abstract and promote the development of Tibetan information processing technology.

title: Design of a LYSO Crystal Electromagnetic Calorimeter for Dark Photon Detection in the DarkSHINE Experiment

description: This paper presents the design and optimization of a LYSO crystal electromagnetic calorimeter (ECAL) for the DarkSHINE experiment, which aims to search for dark photons as potential mediators of dark forces. The ECAL design was evaluated through comprehensive simulations, focusing on optimizing dimensions, material selection, energy distribution, and energy resolution. The ECAL configuration consists of 21$\times$21$\times$11 LYSO crystals, each measuring 2.5$\times$2.5$\times$4 cm$^3$, arranged in a staggered layout to improve signal detection efficiency. A 4 GeV energy dynamic range was established to ensure accurate energy measurements without saturation, which is essential for background rejection and signal identification. A detailed digitization model was developed to simulate the scintillation, SiPM, and ADC behaviors, providing a more realistic representation of detector’s performance. Additionally, the study assessed radiation damage in the ECAL region, highlighting the necessity of radiation-resistant scintillators and silicon sensors.
