为研究薄壳山核桃品种间坚果品质差异，筛选出在湖南地区表现优良的薄壳山核桃，以10个品种薄壳山核桃和2个品种普通核桃为材料，分别对各品种坚果表型性状〔坚果横径、纵径、侧径、果形指数、果实形状、壳面、果壳颜色、果顶、果底（基）、缝合线、横隔膜〕、经济性状（坚果质量、坚果含水率、果壳厚度、出仁率、取仁难易、核仁充实度、核仁饱满度、核仁颜色、核仁风味、核仁含油率）以及其油脂脂肪酸组成及含量进行测定，对薄壳山核桃品质指标进行了相关性分析和主成分分析，综合评价不同品种薄壳山核桃坚果品质。结果表明：在10个品种薄壳山核桃中，‘实生1号’‘德西拉布’‘实生3号’和‘福克特’果形指数较高，分别为2.24、2.15、2.15、1.99；单果质量较大的是‘金奥瓦’‘福克特’和‘德西拉布’，分别为9.24、8.30、8.06 g；出仁率较高的是‘实生4号’和‘金奥瓦’，分别为57.86%、57.08%；含油率较高的为‘福克特’‘佩洛奎’和‘德西拉布’，分别达到72.24%、70.66%、68.24%；薄壳山核桃绝大多数品质指标相互间都有相关性；主成分分析表明，‘德西拉布’的综合得分最高，其次是‘福克特’。综上，风味较优、破壳更简易的‘德西拉布’和含油率高、果实饱满的‘福克特’在湖南地区综合表现优良，适合在湖南地区推广栽培。In order to study the difference in nut quality among varieties of Carya illinoensis (pecan) to screen out pecan with good performance in Hunan province, 10 pecan varieties and 2 walnut varieties were used as materials, and their phenotypic traits (side diameter, transverse diameter and longitudinal diameter, fruit shape index, fruit shape, shell surface, shell color, fruit top, fruit bottom (base), shell seal characteristics, diaphragm) and economic characters (nut weight, nut water content, shell thickness, kernel yield, difficulty in kernel extraction, kernel filling rate, kernel fullness, kernel color, kernel flavor, kernel oil content), and the fatty acid composition and content of oil, were determined and analyzed. In addition, correlation and principal component analysis were carried out on the quality indicators of different varieties of pecan to comprehensively evaluate the nut quality. The results showed that the fruit shape indexes of Shisheng No.1, Desirable, Shisheng No.3 and Forket were higher, with 2.24, 2.15, 2.15 and 1.99, respectively. The heavier single fruit was Kiowa, Forket and Desirable, with 9.24, 8.31 g and 8.06 g, respectively. Shisheng No.4 and Kiowa had higher kernel yield, with 57.86% and 57.08%, respectively. The varieties with high oil content was Forket, Peruque and Desirable, with 72.24%, 70.66% and 68.24%, respectively. Most of the quality indicators of pecans were correlated with each other. The principal component analysis showed that Desirable had the highest overall score, followed by Forket. In conclusion, Desirable with better flavor and easier shell breaking and Forket with high oil content and kernel fullness have excellent comprehensive performance in Hunan, and they are suitable for popularization and cultivation in Hunan.

Objective: Arterial spin labeling (Arterial Spin Labeling, ASL) is a non-invasive, quantitative brain perfusion MR imaging technique at the tissue level that can monitor blood flow changes in the area of acute cerebral infarction at an early stage. This study explores the diagnostic accuracy and sensitivity of 3D-ASL techniques in absolute brain blood flow (aCBF) and relative brain blood flow (rCBF) in wake stroke ischemia and analyzed the evaluation value of relevant parameter values for patient prognostic. Methods: selected 58 wake stroke patients (38 men and 20 women) from January 2019 to December 2020, head MRI TIWI, T2WI, DWI, MRA, 3D-ASL, CBF and ADC, calculated rCBF and other parameters. After three months, patients were evaluated on improved Rankin (mRS) scale and analyzed collected data. Results: According to the mRS scale, there were 36 people, representing 62% and 22 people (mRS≥ 3), representing 37.9%. aCBF has good diagnostic value in the evaluation of prognostic groups; higher rCBF values compared to prognostic groups; ROC curve indicates highest sensitivity and specificity when critical values aCBF=17.90, rCBF=40.9%. Conclusion: Different degrees of perfusion decreased in the waking stroke ischemic lesion area, and 3D-ASL was a reliable predictor on the prognosis of patients with waking stroke.

Artificial intelligence technology has developed rapidly in recent years. While improving the convenience of labor, it also has a certain impact on the current legal system. In particular, artificial intelligence products presently align with the external characteristics of objects protected under intellectual property laws. Consequently, numerous scholars argue that they warrant protection as intellectual property rights, sparking considerable debate. Taking into account the value pursuit of intellectual property law, the stability of the system, and the internal requirements of the objects it protects, this paper proposes denying intellectual property attributes of artificial intelligence products. Instead, it suggests affirming their legal status as fruits and establishing a civil protection framework under the concept of "fruits mode." [ABSTRACT FROM AUTHOR]

In recent years, soft actua tor have attracted m or e and more attention because of their flexibility and strong adaptability. Different from the usual use of the thermal expansion properties of some polymers, we use the thermal shrinkage of gelatin protein (GP) and print the carbon black in the printer toner on to the bio-protein/ cellulose-based film (BPCF) through the printer. The obtained carbon black / BPCF can respond quickly to the temperature. The results show that the carbon black/ BPCF soft actuator can b e controlled b y 808 nm infrared laser to make BPCF shrink and deform. In addition, the motion state of this motion can be further adjusted b y controlling the intensity and direction of the incident light. More importantly, different from ordinary non-degradable polymer-based photothermal actuator, our bioprotein/cellulose-based soft actuator can be melted and regenerated into films for reuse after warm water treatment, and can also be degraded on the soil. This fast response soft actuator shows great potential in environmentally friendly soft actuator. [ABSTRACT FROM AUTHOR]
