针对高位隐蔽性滑坡隐患传统地面调查手段难以识别的问题,笔者所在团队提出了天-空-地协同的滑坡隐患识别与监测“三查”体系,并已在全国范围进行工程化应用,取得了较好的成效,但相关工作的学术报道较少。以滑坡灾害频发的大渡河流域丹巴县段为研究区,开展基于“三查”体系的滑坡隐患识别与监测具体实践。首先利用干涉图堆叠技术(stacking-interferometric synthetic aperture radar,Stacking-InSAR)和小基线集InSAR(small baseline subsets-InSAR,SBAS-InSAR)两种InSAR技术结合高分辨率光学遥感实现整个实验区活动滑坡隐患的广域普查,并对比分析Stacking-InSAR和SBAS-InSAR的识别结果;随后利用机载激光雷达测量技术和无人机航空摄影测量技术对丹巴县城周边高风险区段滑坡隐患进行详查,进一步通过现场调查实现重大滑坡隐患的核查,最后利用SBAS-InSAR技术对典型滑坡隐患形变进行监测分析。协同利用天-空-地观测手段在研究区共探测到滑坡隐患41处,主要为大型古老滑坡堆积体在长期重力作用、河流冲刷和人类工程活动等因素扰动下产生的局部复活,大部分滑坡隐患形变演化趋势与季节性降雨有较好的相关性。

The cooling storage ring (CSR) external-target experiment (CEE) is a spectrometer used in construction to study the properties of nuclear matter in high-baryon density regions at the Heavy-Ion Research Facility in Lanzhou (HIRFL). This study presents the design, simulation, manufacturing, and testing of a half-size prototype of a multi-wire drift chamber (MWDC) for the CEE. First, the performance of the MWDC connected to homemade electronics was simulated. The results demonstrated that an energy resolution of 18.5% % for 5.9-keV X-rays and a position resolution of 194 mu m for protons can be achieved by the current design. Because the size of the largest MWDC reached 176 cm x 314 cm, a set of 98 cm x 98 cm prototypes was built using the new techniques. The positioning accuracy of the anode wires in this prototype is better than 20 mu m. After optimization, using commercially available electronics, the prototype can achieved an energy resolution of 19.7% % for a Fe-55 X-ray source. The CEE-MWDC detector and electronics were simultaneously tested. An energy resolution of 22% % was achieved for the Fe-55 source; the track residuals were approximately 330 mu m for the cosmic rays. The results demonstrate that the current design and techniques meet the requirements of the CEE-MWDC array.

目的检验GOAL问卷和Epworth嗜睡量表(Epworth sleeping scale,ESS)在筛查阻塞性睡眠呼吸暂停(obstructive sleep apnea,OSA)中联合应用的效能。方法从睡眠医学中心招募2958例参与者,完成夜间多导睡眠图监测和筛查问卷,包括GOAL、ESS、STOP-Bang问卷(SBQ)和NoSAS评分。评估每个量表的敏感度、特异度、阳性预测值、阴性预测值、诊断优势比(diagnostic odds ratio,DOR)和受试者工作特征(ROC)曲线下面积(area under the curve,AUC)。结果GOAL问卷在筛选OSA方面具有更高的敏感度和DOR(敏感度为0.831,DOR为3.72),优于STOP-Bang问卷和NoSAS评分。当GOAL问卷和ESS量表相结合时,特异度和DOR分别显著上升至0.894和4.22。GOAL问卷得分为3且ESS量表≥11分的参与者极有可能患有OSA,概率为0.96。结论GOAL问卷和ESS量表相结合具有优秀的诊断能力,可有效筛查OSA。对疑似OSA患者进行GOAL问卷后的第二阶段进行ESS量表筛查,可以提高预测准确性和早期诊断。

Over the past 70 years, the semiconductor industry has undergone transformative changes,largely driven by the miniaturization of devices and the integration of innovative structures and materials. Two-dimensional(2D) materials like transition metal dichalcogenides(TMDs) and graphene are pivotal in overcoming the limitations of silicon-based technologies, offering innovative approaches in transistor design and functionality, enabling atomic-thin channel transistors and monolithic 3D integration. We review the important progress in the application of 2D materials in future information technology, focusing in particular on microelectronics and optoelectronics. We comprehensively summarize the key advancements across material production, characterization metrology, electronic devices, optoelectronic devices, and heterogeneous integration on silicon. A strategic roadmap and key challenges for the transition of 2D materials from basic research to industrial development are outlined. To facilitate such a transition, key technologies and tools dedicated to 2D materials must be developed to meet industrial standards, and the employment of AI in material growth, characterizations, and circuit design will be essential. It is time for academia to actively engage with industry to drive the next 10 years of 2D material research.

为了建立一种基于深度学习卷积神经网络(DCGAN)的路面裂缝检测模型,提高特殊路面裂缝(如模糊裂缝、浅裂缝等)的识别准确率,提出了基于DCGAN预处理和残差密集注意力网络(RDAN)的路面裂缝识别方法。该方法基于对抗学习的思想,在数据预处理中保留了高分辨率的裂缝特征,同时抑制背景噪声的影响,将模糊裂缝增强为清晰裂缝,将浅色裂缝重建为深色裂缝,提升模型训练、识别效果;在模型训练中,提出了一种全新的适用于路面裂缝识别的RDAN;基于传统的残差网络和密集网络的结构进行融合改进,在元素维度和通道维度同步进行层与层之间特征的传递,改善深度卷积神经网络训练过程中的退化问题;通过引入卷积块注意力模块,在空间与通道2个维度实现自适应特征优化,进一步提升网络在实际复杂路面背景下的裂缝特征提取能力,抑制背景噪声的干扰。结果表明:基于DCGAN预处理和RDAN的路面裂缝识别方法在CiCS50000实际工程数据集及多个公开数据集上取得了最优的识别效果,在CiCS50000数据集准确率、精确率、召回率和Dice相似系数上分别达到了97.51%,87.05%,83.36%和81.02。

针对偏振光谱图像融合方法在地物混杂背景遥感探测中多尺度变换融合图像存在边缘轮廓细节模糊、对比度不佳的问题,提出一种基于非下采样轮廓波变换的稀疏表示与引导滤波器相结合的图像融合方法,以改善融合图像的质量和视觉效果。首先,该方法通过非下采样轮廓波变换对光谱图像和偏振图像进行多尺度多方向分解,进而将图像分解成不同子带内的特征信息。其次,低频子带采用稀疏表示融合,从而降低融合图像中物体对比度损失。此外,采用引导滤波器融合高频子带,以增强图像轮廓细节信息。最后,对低频与高频融合系数进行非下采样轮廓波逆变换,最终得出融合图像。分析表明融合图像对比度相对于原始光谱图像与偏振度图像分别提升了54.5%和15.4%,更容易区分混杂背景下阴影中的物体。基于此方法对偏振光谱成像仪所采集的不同波长下的光谱与偏振图像进行融合,并实现真彩还原。真彩还原图像证明此融合方法在保留混杂背景下的环境信息的同时实现了物体和背景的有效区分,有效提高了偏振光谱遥感探测成像的图像质量,有助于提升偏振光谱遥感探测成像中图像信息的完整性和真实性,扩大其在复杂环境遥感探测和图像识别中的应用范围。
