III-nitride materials are of great importance in the development of modern optoelectronics,but they have been limited over years by low light utilization rate and high dislocation densities in heteroepitaxial films grown on foreign substrate with limited refractive index contrast and large lattice ***,we demonstrate a paradigm of high-throughput manufacturing bioinspired microstructures on warped substrates by flexible nanoimprint lithography for promoting the light extraction *** design a flexible nanoimprinting mold of copolymer and a two-step etching process that enable high-efficiency fabrication of nanoimprinted compound-eye-like Al2O3 microstructure(NCAM)and nanoimprinted compound-eye-like SiO_(2)microstructure(NCSM)template,achieving a 6.4-fold increase in throughput and 25%savings in economic costs over stepper projection *** to NCAM template,we find that the NCSM template can not only improve the light extraction capability,but also modulate the morphology of AlN nucleation layer and reduce the formation of misoriented GaN grains on the inclined sidewall of microstructures,which suppresses the dislocations generated during coalescence,resulting in 40%reduction in dislocation *** study provides a low-cost,high-quality,and high-throughput solution for manufacturing microstructures on warped surfaces of III-nitride optoelectronic devices.

AGV Scheduling Optimization of Automated Port Based on Disruption Management

Journal of Transportation Technologies 2024年第3期14卷 423-444页

The recent rapid development of China’s foreign trade has led to the significant increase in waterway transportation and automated container ports. Automated terminals can significantly improve the loading and unloading efficiency of container terminals. These terminals can also increase the port’s transportation volume while ensuring the quality of cargo loading and unloading, which has become an inevitable trend in the future development of ports. However, the continuous growth of the port’s transportation volume has increased the horizontal transportation pressure on the automated terminal, and the problems of route conflicts and road locks faced by automated guided vehicles (AGV) have become increasingly prominent. Accordingly, this work takes Xiamen Yuanhai automated container terminal as an example. This work focuses on analyzing the interference problem of path conflict in its horizontal transportation AGV scheduling. Results show that path conflict, the most prominent interference factor, will cause AGV scheduling to be unable to execute the original plan. Consequently, the disruption management was used to establish a disturbance recovery model, and the Dijkstra algorithm for combining with time windows is adopted to plan a conflict-free path. Based on the comparison with the rescheduling method, the research obtains that the deviation of the transportation path and the deviation degree of the transportation path under the disruption management method are much lower than those of the rescheduling method. The transportation path deviation degree of the disruption management method is only 5.56%. Meanwhile, the deviation degree of the transportation path under the rescheduling method is 44.44%.

Sohd-solid reaction under low heat or low temperature is an approach to synthesize various kinds of materials that were widely used in electrochemistry field. In this paper a theoretical treatment has been presented for analyzing the mechanism of sohd-solid reaction and deriving a series of formulae to describe the variation and rate of reactions. This new model has been used in the manufacturing of spinel Li4Ti5O12. The results show that this new model works very well and will play a useful role for guiding the manufacturing of electrochemical materials.

AIM: To investigate the relationship between single nucleotide polymorphisms in the uridine-diphosphoglucurono-syltransferase (UGT) UGT1A7 and UGT1A1 genes and patients suffering from colorectal cancer (CRC). METHODS: A case-control study was designed in order to investigate the genotypes of the UGT1A7 and UGT1A1 genes, which were identified by the polymerase chain reaction-restriction fragment length polymorphism (RFLP) method, for 268 CRC patients and 441 healthy controls. RESULTS: The results of simple logistical regressions revealed odds ratios (ORs) of 1.97 (P<0.001),1.91 (P<0.001),and 2.03 (P<0.001) for patients who carried the UGT1A7*1/*3 genotype,UGT1A7*3 allele,and variant-211 UGT1A1 *** interaction of UGT1A7*3 allele and variant-211 UGT1A1 allele produced an additive effect on the risk for the development of CRC [observed OR (2.34) greater than expected OR (1.59)]. For the 268 patients, the results of simple logistical regressions indicated that the OR of developing metastases was 4.90 (P<0.001) and 4.89 (P<0.001) for the individuals possessing UGT1A7*3 allele and variant-211 UGT1A1 allele, respectively. The results of multivariate logistical regressions confirmed these findings (OR = 2.51, P= 0.01; and OR=2.71,P=0.01,respectively).The interaction of these two variants resulted in an additive effect on the risk for metastases amongst patients [observed OR (6.83) greater than expected OR (4.56)]. CONCLUSION: In conclusion, carriage of the UGT1A7*3 allele, as well as variant-211 UGT1A1 allele represents a risk factor for the development of, and a determinant for, metastases associated with CRC patients.

1999—2021年,中国地质调查局组织实施的土地质量地球化学调查共获得670321件表层组合土壤样品(0~20 cm)和167746件深层组合土壤样品(150~180 cm),覆盖面积约266.5万km^(2),囊括我国人口集中区和大部分耕地。对相关土壤样品均按统一标准分析了54项化学指标(Ag、As、Au、B、Ba、Be、Bi、Br、Cd、Ce、Cl、Co、Cr、Cu、F、Ga、Ge、Hg、I、La、Li、Mn、Mo、N、Nb、Ni、P、Pb、Rb、S、Sb、Sc、Se、Sn、Sr、Th、Ti、Tl、U、V、W、Y、Zn、Zr、SiO_(2)、Al_(2)O_(3)、TFe_(2)O_(3)、MgO、CaO、Na_(2)O、K_(2)O、pH、全碳和有机碳)。本文利用这些数据讨论了中国土壤54项指标的地球化学背景值、基准值及其上下限的划定方法和基本特征,并对我国耕地土壤背景与现行环境、养分等相关标准中各种阈值进行了对比。结果显示:在全国尺度上,各项指标表层与深层Spearman相关系数均高于0.50,表明表层土壤中大部分指标都继承了深层土壤的含量与分布特征。54项指标中仅C_(org)、TC、N、S、Se、Hg、Br、Cd和P等指标背景值相对基准值发生了较大变化。我国耕地土壤中,Cd的农用地污染风险筛选值在背景范围内,Hg、As、Pb和Cr的筛选值则高于背景上限值。由于许多指标的空间分布存在着巨大的差异,在全国范围内划定一个统一的背景值并不利于土壤资源的精细化管理和保护,因此有必要在全国尺度地球化学背景与基准的基础上建立区域尺度地球化学背景与基准,为政府部门合理制定相关土壤环境质量的标准和保护法规提供依据。

AIM： To identify the risk factors in predicting the out- come of acute-on-chronic hepatitis B liver failure pa- tients. METHODS： We retrospectively divided 113 patients with acute-on-chronic liver failure-hepatitis B virus （ACLF-HBV） and without concurrent hepatitis C or D virus infection and hepatocellular carcinoma into two groups according to their outcomes after anti-HBV therapy. Their demographic, clinical, and biochemical data on the day of diagnosis and after the first week of treatment were analyzed using the Mann-Whitney U test, Fisher＇s exact test, and a multiple logistic regres- sion analysis. RESULTS： The study included 113 patients （87 men and 26 women） with a mean age of 49.84 years. Fifty- two patients survived, and 61 patients died. Liver failure （85.2%）, sepsis （34.4%）, and multiple organ failure （39.3%） were the main causes of death. Mul- tivariate analyses showed that Acute Physiology and Chronic Health Evaluation （APACHE） Ⅱ scores ≥ 12 [odds ratio （OR） = 7.160, 95% CI： 2.834-18.092, P 〈 0.001] and positive blood culture （OR = 13.520, 95% CI： 2.740-66.721, P = 0.001） on the day of diagnosis and model for end-stage liver disease （MELD） scores 28 （OR = 8.182, 95% CI： 1.884-35.527, P = 0.005） after the first week of treatment were independent predictors of mortality. CONCLUSION： APACHE II scores on the day of diag- nosis and MELD scores after the first week of anti-HBV therapy are feasible predictors of outcome in ACLF- HBV patients.
