Dehazing technology has made great progress on a single image, but due to the high time complexity, it cannot meet the real-time requirements of HD video dehazing. Aiming at this problem, this paper proposed a dark channel prior dehazing algorithm based on hardware architecture optimization. It used the hardware-oriented dual-scale joint filtering method and threshold comparison method to simplify the computational complexity of transmittance and atmospheric light value. At the same time, it used the interframe dependency constraint to suppress the flicker noise in the video defogging. The experimental results show that the dehazing speed of the proposed algorithm reaches 148. 2 Mpixel/s, which is about 55 times higher than that implemented by software programming, and the dehazing speed offull HD video at 1920 x 1080 resolution reaches 69 fps, meeting the real-time requirements and high dehazing quality.

Objective To detect the level of microRNA-181b （miR-181b） in plasma and explore the clinical significance in the patients with osteosarcoma. Methods 25 patients with osteosarcoma and 30 healthy controls were enrolled. The level of miR-181b in plasma was detected by quantitative stem-loop RT-PCR. The relationships between the level of miR-181b and clinicopathological characteristics of osteosarcoma were analyzed. Results The level of miR-181b in plasma of patients with osteosarcoma （0.62±0.25） was statistically higher than that of healthy controls （0.41±0.18） （ < 0.01） . The level of miR-181b in plasma of patients with osteosarcoma was not correlated with gender，age，tumor size，tumor site，histological type and Enneking stage （ > 0.05） . Conclusion The level of miR-181b in plasma of patients with osteosarcoma were increased. MiR-181b may participate in the pathology of osteosarcoma. [ABSTRACT FROM AUTHOR]

In order to explore the response mechanism of AP2/ERF gene family in the water stress of O. europaea, this study performed transcriptome sequencing on the roots and leaves of two cultivars ‘Frantoio' and ‘TYZ-1' that were under drought and flooding stresses. And based on the whole genome data, the protein physicochemical properties, gene structure and system evolution of AP2/ERF transcription factor in O. europaea were analyzed. At the same time, the difference in gene expression of AP2/ERF transcription factor related to water stress in the two O. europaea cultivars was analyzed by transcriptome sequencing data and verified by RT-qPCR. The results were as follows: (1) A total of 110 AP2/ERF gene family members were identified in O. europaea. The amino acid size of the 110 proteins was 173-717bp, there was no signal peptide and it was a non-secreted protein. The phylogenetic tree was constructed between O. europaea AP2/ERF and model plant Arabidopsis AP2/ERF protein. It was found that O. europaea AP2/ERF protein was divided into four categories, AP2, RAV, ERF and Solosist. Among them, ERF was divided into two subtypes, ERF and DREB. ERF included six subtypes of ERF B1 to ERF B6, and DREB included six subtypes of DREB A1 to DREB A6, which was consistent with the classification of the model plant Arabidopsis AP2/ERF. Each subfamily contained AP2/ERF proteins of O. europaea and Arabidopsis at the same time, indicating that the AP2/ERF family of Arabidopsis and O. europaea were similar in evolution. (2) The analysis of gene structure and conserved elements found that the proteins of the same subfamily of O. europaea AP2/ERF had the same gene structure and conserved elements. Combining gene expression with genes with known water regulation functions in the evolutionary tree, it was preliminarily speculated that OeAP2-75, OeAP2-97, OeAP2-101, OeAP2-23 and OeAP2-13 were closely related to the water regulation of O. europaea, OeAP2-13, OeAP2-28, OeAP2-104, OeAP2-75, OeAP2-80 and OeAP2-50 had different expression levels in the two cultivars. It is speculated that this may be the reason for the different resistance of ‘Frantoio' and ‘TYZ-1'. (3) The RT-qPCR technique was used to detect the expression changes of O. europaea AP2/ERF gene under different stresses. The results showed that OeAP2-101, OeAP2-28 and OeAP2-42 were significantly up-regulated by water stress, which was consistent with the results of transcriptome analysis. The results of this study lay a foundation for the research on the stress resistance expression and gene function of the AP2/ERF family genes of O. europaea, and provides the method and theoretical basis for the selection of drought-resistant and flood-tolerant rootstock cultivars of O. europaea.

【Objective】 The current paper was conducted to study the relationships between different altitudes and the economic traits of walnut fruit, the degree of variation of main fatty acids, and the degree of variation of main fatty acids in Yunnan’s main walnut variety, Juglans sigillata cv. Yanbipao, so as to reveal the variation characteristics of its fruit shape and nutritional components, determine the best suitable cultivation area for a specific variety and to provide a theoretical basis for further developing applications.【Method】 Taking Yangbipao walnut as the test material, from the altitude of 1500 meters, the fruit was sampled every time the altitude rising by 100 meters, and the economic traits and fatty acid quality indicators of the fruit were measured and analyzed. The economic forest research method was used to determine the economic properties of nuts, main fatty acid content. Correlation analysis, stepwise regression analysis and determination degree analysis were carried out to reveal the relationship between each index and altitude change. 【Result】 At an altitude of 1500 meters, the thickest shell was 1.105 mm; At an altitude of 1700 meters, the smallest seed weight, kernel weight, and three-diameter mean were 9.298 g, 4.961 g, and 32.240 mm respectively; At an altitude of 1900 meters, the lowest rate of kernel release was 50.6%; At an altitude of 2300 meters, the highest values were found for seed weight, kernel weight, kernel release rate, and three-diameter mean, while the thinnest shell was 1.015 mm. The altitude had a negative correlation with shell thickness, a significant positive correlation with kernel release rate, longitudinal diameter, and transverse diameter, a positive correlation with seed weight, kernel weight, horizontal diameter, and three-diameter mean, and a positive correlation with oleic acid, peanut acid, and peanut oleic acid, as well as a negative correlation with stearic acid, linoleic acid, and linolenic acid. The altitude had the greatest direct effect on peanut oleic acid, and the indirect effect on linoleic acid was greater than the direct effect. The altitude mainly affected the variation in the properties of linoleic acid, peanut acid, and peanut oleic acid. 【Conclusion】 In the study area, altitude has a comprehensive impact on the economic traits and main fatty acid content of Yangbipao walnut kernel fruits, within the range of 1500-2300 meters, these traits perform well. Through comprehensive analysis, the walnut quality is the best at an altitude of 1700-2100 meters. [ABSTRACT FROM AUTHOR]

[Objective] Flower yellowing disease ( FYD) is one of the most significant diseases affecting Zanthoxylum sp. in recent years, leading to yield losses in susceptible Zanthoxylum spp. In the study, high-throughput sequencing technology was employed to analyze the potential pathogens responsible for FYD, aiming to provide a basis for pathogen identification and disease control. [ Method] The flower and leaf samples of four plants with FYD symptoms and two asymptomatic plants of Z. armatum var. yongqing 1 were collected for virome analysis. [Result] Sequencing data analysis indicated that a total of 484 contings from six samples matrched 15 virus species belonging to 12 different viral families. Among these six samples, four previously reported viruses were detected in Z. armatum var. novemfolius: Green Sichuan pepper-nepovirus ( GSPNe V), Green Sichuan pepper-idaeovirus ( GSPIV), Green Sichuan pepper-enamovirus ( GSPEV), Green Sichuan pepper-nucleorhabdovirus ( GSPNuV). Notably, previously unreported viruses in Zanthoxylum spp. included two novel RNA viruses tentatively named Yongqing green pepper-associated umhravirus and Yongqing green pepper-associated ssRNA negative-strand virus. Additionally, Potato virus Y (PVY) was detected in symptomatic D-2 and asymptomatic H-1 samples. Potato virus M (PVM), Potato virus H ( PVH), Potato virus S ( PVS), all belonging to the genus Carlavirus in the family Betaflexiviridae, were identified in FYD plant samples of D-2, D-3 and D4. Furthermore, the grapevine rubestris stem pitting associated virus (GRSPAV) of the genus Foveavirus was detected exclusively in the D-1 sample. [ Conclusion] All four reported viruses as well as two new unreported viruses were detected in the sequenced samples from Y ongqing 1, and the genus Carlavirus, which was only present in the symptomatic group, was detected, and it was inferred that the highly expressed viruses of the genus Carlavirus should be regarded as one of the factors that induced FYD.

As the largest magmatic Cu-Ni(-Co)sulfide deposit in China and the third largest in the world, the reserves of Co in Jinchuan deposit account for more than 30% of the total reserves in China. It is of great significance to study the characteristics of Co-bearing minerals of ores in Jinchuan deposit and their extraordinary enrichment occurrence regularity for the core scientific problem of metallogenic kinetics of key metal elements, which is extraordinary enrichment metallogenic process and its driving mechanism. The metallogenic mechanism and regularity of Co were discussed by studying the formation and mineralization characteristics of Jinchuan deposit. At the same time, the occurrence state of Co was studied on the main controlling factors of element symbiotic-differentiation and co-associated enrichment mineralization. The results show that there are very few independent Co and Co-bearing minerals of ores in Jinchuan deposit, most of which are Co-Ni sulfide minerals and sulfur-arsenic Co-Ni minerals, mainly including cobalt polydymite, Co-bearing nickelglance, nickel cobaltite and Co-Ni gersdorffite. Among them, nickel cobaltite and Co-Ni gersdorffite are often associated with pyrrhotite or pentlandite, especially most of them exist in pentlandite and Ni-Cu microcrystallites, suggesting that their genesis is also related to magmatism. Co is mainly dispersed in sulfide mineral group(about 90.30%), of which 97% is dispersed in pentlandite and Ni-Cu microcrystallites. About 2.85% of them are dispersed in hydroxymagnesium sulfide mineral group, of which 44.46% is distributed in vallerite; 6.51% is dispersed in gangue mineral group, of which about 73% is dispersed in serpentine. The Ni/Co ratio in pentlandite is about 44.00, and that in Ni-Cu microcrystallites is about 2.00. The Ni/Co ratio in magnetite is about 11.00; among the most widely distributed gangue minerals such as serpentine in Jinchuan deposit, the Ni/Co ratio is about 24.00. There is a certain linear relationship between the contents of Co and Ni of ores. Both Co and Ni mainly occur in pentlandite, indicating that there is a close genetic relationship between Co and Ni.
