研判新型农业经营主体发展的外部环境、内生动力和演化趋势,增强农业农村发展新动能,是关系中国农业农村现代化的重大战略。论文基于2000—2022年农业农村部公布的农业产业化国家重点龙头企业、全国农民合作社和家庭农场典型案例名单以及中国农业企业黄页中的新型农业经营主体相关数据,通过空间计量分析和生存分析,探究其生存的空间格局及其影响因素。研究发现:①新型农业经营主体进入和退出农业市场的数量呈现倒“U”型曲线,实存数量呈逐渐上升的状态。②新型农业经营主体的生存时间在区域间形成差异化格局,高—高集聚区主要集中在中东部地区。③“个体特征和创新能力”因素对新型农业经营主体生存时间有正向影响,“阶段演变”对其生存时间有负向影响。④随着成立阶段的推移,新型农业经营主体资产规模和关联经济组织数量对其生存时间的影响作用逐渐下降,地理区域因素影响作用也逐渐减弱。研究结论可为新型农业经营主体生存分析提供实证依据,为分析其发展演化的地理特征提供借鉴参考。

基于CGE模型和SDA方法分析模拟了8种碳定价机制对宏观经济、减排目标和驱动因素的影响程度。结果表明:由于碳税和碳交易的价格形成过程不同,开征碳税对中国宏观经济的冲击更大,需要制定配套的税收返还措施,以有效弥补部分社会福利损失;价格-数量混合型碳定价机制对产业关联性较强部门如“交通运输设备制造业”“建筑业”和“化石能源”等部门的降碳效果更为显著;碳排放强度效应和中间投入结构效应是促进碳减排的主要驱动因素,且不同驱动因素对不同产业部门的作用程度存在显著差异。应坚持“政府+市场”双轮驱动,着力构建碳税与碳交易协同互补的碳定价机制,助力中国如期实现“碳达峰、碳中和”目标。

Objective: With the aging population and changes in lifestyle, lumbar spinal stenosis has become a common spinal disorder. Treatment modalities have been advancing, and the application of Enhanced recovery After Surgery (ErAS) principles provides a new approach to postoperative recovery in patients. This study aims to investigate the clinical application effects of ErAS principles in single-level lumbar spinal stenosis surgery. Methods: This study included 64 patients who underwent lumbar fusion surgery in the Spinal Surgery Department of Baise People’s Hospital from July 2022 to July 2024. These patients were divided into an experimental group (ErAS group, 33 cases) and a control group (conventional group, 31 cases) based on perioperative care, receiving ErAS principles and traditional treatment, respectively. A comparison was made between the two groups in terms of gender, age, BMI, intraoperative blood loss, postoperative length of hospital stay, postoperative complications, hospital costs, VAS scores (preoperative/postoperative day 3), and ODI scores (preoperative/postoperative day 3). results: There were no significant differences in gender, age, and BMI between the ErAS group and the conventional group (gender: χ2 = 0.5008, P = 0.4792;age: 54.55 ± 8.51 years vs. 57.39 ± 8.16 years, P = 0.0892;BMI: 25.11 ± 2.70 vs. 24.77 ± 2.75, P = 0.3098). However, dur.ng surgery, patients in the ErAS group had significantly less blood loss than those in the conventional group (197.58 ± 195.51ml vs. 438.71 ± 349.22 ml, P = 0.0006), and the postoperative length of hospital stay was significantly shorter (7.00 ± 2.24 days vs. 11.55 ± 5.23 days, P = 0.0000). On postoperative day 3, VAS scores were significantly better in the ErAS group compared to the conventional group (3.70 ± 0.88 vs. 4.32 ± 0.87, P = 0.0031), and the ODI scores showed significant improvement as well (46.00 ± 3.04 vs. 48.00 ± 3.39, P = 0.0078).

Goji berry is a famous edible and medicinal substance around the world. In this research， 15 phenylpropionyl phenylethylamine derivatives (1-15)， including one new compound (1)， were separated and identified from goji berry. All isolates were elucidated via extensive NMr spectral analyses and chemical techniques. Six known isolates were first obtained from Lycium genus. Six isolates were effectively split into double chromatographic peaks accompanied by the basically identical areas， indicating they belong to racemates. The OrAC experiment indicated that all isolates displayed a capacity of scavenging free radicals， and most of them exhibited higher OrAC values than EGCG. In ethanol/palmitic acid (PA)-established in vitro hepatocyte injury model， four phenylpropionyl phenylethylamine derivatives (1， 2， 9， and 15) significantly alleviated hepatocyte injury， among which compound 1 exerted the str.ngest protective activity. Notably， the hepatoprotective effect of compound 1 was further confirmed in ethanol-established liver damage mouse model， reflected by the reduction of lipid accumulation and the attenuation of pathological alteration. Combined with the in vitro results， the in vivo observations suggested that compound 1 suppressed cell apoptosis and the outburst of inflammation. Our findings provided first-hand evidence proving that goji berry-derived phenylpropionyl phenylethylamine derivatives hold a potential in treating alcoholic liver disease.

近年来,面向动态场景的多曝光图像融合技术取得重大进展.其中,基于深度学习的方法在视觉效果和运算效率上都远超传统算法,成为高动态范围成像技术的主流.然而,现有基于深度学习的融合方法都以有监督学习的方式实现,过度依赖真值图像,难以被广泛应用于实际场景中.本文提出了一个基于深度自监督学习的动态多曝光图像融合网络,主要贡献包括:设计自监督的动态多曝光融合网络框架,探索高动态范围图像与低动态范围图像序列的内在关联;提出基于注意力机制的全局去伪影模块,使用全局文本模块减少动态融合产生的运动伪影,增强图像细节;提出融合重建模块,通过残差和稠密连接实现多层次特征之间的信息流动;设计运动掩膜引导的自监督损失函数,用于网络的高效训练.实验表明,与现有方法相比,本文提出的方法在高动态范围图像重建的主观和客观质量上均表现较好,运算效率显著提升.
