利用高光谱遥感影像可以开展精细化土地覆盖制图,相关技术已在农业生产、植被生态等领域中广泛应用。然而,现有的面向像元或对象的分析方法在制图单元的合理性、精细性尚有欠缺。鉴于此,提出了基于随机森林的地块级高光谱土地覆盖制图思路,并利用雄安新区马蹄湾村高光谱影像开展实验与精度评估,综合类型精度和形态精度指标,探析不同划分尺度的制图优劣。在类型精度方面,结果表明:地块级高光谱土地覆盖制图效果及类型精度最优;在形态精度方面,发现地块级土地划分优于对象级划分结果。综合对比两类精度后得出,面向地块的高光谱土地覆盖制图可生产更符合用户需求的信息成果,具有较高的潜在应用价值。

在地学领域中,空间推测是根据已知样本点运用连接函数推测未知区域数值的过程.基于回归克里金(Regression Kriging, RK)以及随机森林(Random Forest, RF)等机器学习算法的空间推测方法已在土壤水质反演、空气质量预测等领域中得到广泛应用,通过引入缓冲距离、邻近点的观测值以及到预估点的水平距离等方式逐步发展出“Random Forest for spatial prediction (RFsp)”、“Random Forest Spatial Interpolation (RFSI)”等模型.为克服RFSI模型中距离的不足并获得更加精确的推测结果,本文在其基础上引入反距离加权策略,考虑将邻近点的观测值以及到预估点的距离进行组合,提出了一种基于水平位置距离的反距离加权随机森林(Random Forest with Inverse Distance Weighted Based on Location Distance, RFIdw)模型.基于SIC97(Spatial Interpolation Comparison 97)数据集开展的对比实验表明,本文提出的RFIdw相较于RFSI、RFsp可获得更加精准的空间推测结果,同时输出有效的不确定性表达信息.

Background Despite its prevalence, there is ongoing debate regarding the optimal management strategy for chronic subdural hematoma (CSDH), reflecting the variability in clinical presentation and treatment outcomes. This ambidirectional, nationwide, multicenter registry study aims to assess the efficacy and safety of multimodality treatment approaches for CSDH in the Chinese ***/design A multicenter cohort of CSDH patients from 59 participating hospitals in mainland China was enrolled in this study. The treatment modalities encompassed a range of options and baseline demographics, clinical characteristics, radiographic findings, and surgical techniques were documented. Clinical outcomes, including hematoma resolution, recurrence rates, neurological status, and complications, were assessed at regular intervals during treatment, 3 months, 6 months, 1 year, and 2 years *** Between March 2022 and August 2023, a comprehensive cohort comprising 2173 individuals who met the criterion was assembled across 59 participating clinical sites. Of those patients, 81.1% were male, exhibiting an average age of 70.12 ± 14.53 years. A historical record of trauma was documented in 48.0% of cases, while headache constituted the predominant clinical presentation in 58.1% of patients. The foremost surgical modality employed was the burr hole (61.3%), with conservative management accounting for 25.6% of cases. Notably, a favorable clinical prognosis was observed in 88.9% of CSDH patients at 3 months, and the recurrence rate was found to be 2.4%.Conclusion This registry study provides critical insights into the multimodality treatment of CSDH in China, offering a foundation for advancing clinical practices, optimizing patient management, and ultimately, improving the quality of life for individuals suffering from this challenging neurosurgical *** registration ChiCTR2200057179

针对孤岛工作面开采时两侧煤柱应力集中问题,以山东能源协庄煤矿401工作面为研究对象,通过数值模拟和现场实测研究了孤岛工作面回采时煤柱采动应力和塑性区分布特征。模拟结果表明:当煤柱宽度由10 m增加至40 m时,相邻工作面两侧高应力区范围以及对大巷应力分布的影响逐渐减小,最大水平应力分别降低了13%、10.5%和6.2%;煤柱宽度为10 m和20 m时,煤柱出现塑性破坏失去承载能力;煤柱宽度为30 m和40 m时,煤柱两侧出现塑性破坏,中心未出现塑性破坏,仍具有承载能力;基于模拟结果,确定合理煤柱宽度为30 m,现场监测结果表明,该煤柱宽度可以实现孤岛工作面的安全回采。
