The problem of scheduling jobs on uniform parallel machines with makespan ( C max ) minimization objective was studied. Due to its non-deterministic polynomial-time ( N ) hard nature,it is difficult to achieve an optimal solution with traditional optimization methods. For this reason,a novel modified differential evolution ( MDE) was proposed to tackle the uniform parallel machine scheduling problem ( UPMSP ) ,taking out the mutation operation and introducing the roulette wheel selection strategy into conventional differential evolution ( DE ) . In MDE, more high quality individuals can be reserved to update the population. And the control parameter F in conventional DE was removed,which could simplify the DE. To verify the proposed MDE,162 randomly generated instances were conducted. The comparison results with DE,genetic algorithm ( GA ) ,simulated annealing ( SA ) , and largest processing time ( LPT) method show that the MDE is an efficient and competitive approach in solving UPMSP.

为了明确适宜水稻品种伍两优华占的栽培方式,对其在人工移栽和人工直播2种不同种植方式下的农艺性状以及产量进行了比较研究。结果表明:人工直播方式每穗总粒数和实粒数虽然低于人工移栽方式,但分蘖率更强,结实率和有效穗数也明显高于人工移栽方式;无论是理论产量还是实收产量,均高于人工移栽方式。从综合效益来看,与人工移栽方式相比,人工直播方式节省了人工和育苗成本,劳动强度降低,生育进程显著提前,能更大程度地提高伍两优华占的种植效益。

激光点云匹配是影响激光SLAM系统精度和效率的关键因素.传统激光SLAM算法无法区分场景结构,且在非结构化场景下由于特征提取不佳而出现性能退化.为此,提出一种联合CPD(coherent point drift)面向复杂场景的自适应激光SLAM算法CPD-LOAM.该算法提出一种基于预判和验证相结合的场景结构辨识方法,首先引入场景特征变量对场景结构进行初步判断,然后从几何特征角度通过表面曲率对其进行验证,增强对场景结构辨识的准确性.此外,在非结构化场景下添加CPD算法进行点云预配准,进而利用ICP算法进行再配准,解决该场景下的特征退化问题,从而提高点云配准的精度和效率.实验结果表明,提出的场景特征变量以及表面曲率可以根据设置的阈值有效地区分场景结构,在公开数据集KITTI上的验证结果显示,CPD-LOAM较LOAM算法定位误差降低了84.47%,相较于LeGO-LOAM与LIO-SAM算法定位精度也分别提升了55.88%和30.52%,且具有更高的效率和鲁棒性.

AIM: To investigate the effects of superoxide dismutase (SOD) polymorphisms (rs4998557 , rs4880), Helicobacter pylori (H. pylori ) infection and environmental factors in gastric cancer (GC) and malignant potential of gastric precancerous lesions (GPL). METHODS: Copper-zinc superoxide dismutase (SOD1, CuZn-SOD)-G7958A (rs4998557 ) and manganese superoxide dismutase (SOD2, Mn-SOD)-Val16Ala (rs4880 ) polymorphisms were genotyped by SNaPshot multiplex polymerase chain reaction (PCR) in 145 patients with GPL (87 cases of gastric ulcer, 33 cases of gastric polyps and 25 cases of atrophic gastritis), 140 patients with GC and 147 healthy controls. H. pylori infection was detected by immunoblotting analysis. RESULTS: The SOD1-7958A allele was associated with a higher risk of gastric cancer [odds ratio (OR) = 3.01, 95% confidence intervals (95% CI): 1.83-4.95]. SOD216Ala/Val genotype was a risk factor for malignant potential of GPL (OR = 2.04, 95% CI: 1.19-3.49). SOD216Ala/genotype increased the risk of gastric cancer (OR = 2.85, 95% CI: 1.66-4.89). SOD1-7958A/genotype, SOD2-16Ala/genotype, alcohol drinking, positive family history and type Ⅰ H. pylori infection were associated with risk of gastric cancer, and there were additive interactions between the two genotypes and the other three risk factors. SOD2-16Ala/Val genotype and positive family history were associated with malignant potential of GPL and jointly contributed to a higher risk for malignant potential of GPL (OR = 7.71, 95% CI: 2.10-28.22). SOD1-7958A/genotype and SOD2-16Ala/genotype jointly contributed to a higher risk for gastric cancer (OR = 6.43, 95% CI: 3.20-12.91). CONCLUSION: SOD1-7958A/and SOD2-16Ala/-genotypes increase the risk of gastric cancer in Chinese Han population. SOD2-16Ala/-genotype is associated with malignant potential of GPL.
