针对神经网络难以利用少量标注数据获取足够的信息来正确分类图像的问题,提出了一种融合随机深度网络和多尺度卷积的关系网络——SDM-RNET.首先在模型嵌入模块引入随机深度网络用于加深模型深度,然后在特征提取阶段采用多尺度深度可分离卷积替代普通卷积进行特征融合,经过骨干网络后再采用深浅层特征融合获取更丰富的图像特征,最终学习预测出图像的类别.在mini-ImageNet、RP2K、Omniglot这3个数据集上对比该方法与其他小样本图像分类方法,结果表明在5-way 1-shot和5-way 5-shot分类任务上该方法准确率最高.

We propose an aggregation model of a two-species system to mimic the growth of cities＇ population and assets, in which irreversible coagulation reactions and exchange reactions occur between any two aggregates of the same species, and the monomer-birth reactions of one species occur by the catalysis Of the other species. In the case with population-catalyzed birth of assets, the rate kernel of an asset aggregate Bκ of size k grows to become an aggregate Bκ＋1 through a monomer-birth catalyzed by a population aggregate Aj of size j is J（κ,j） = Jkjλ. And in mutually catalyzed birth model, the birth rate kernels of population and assets are H（k,j）=Hkjη and J（k,j） = Jkjλ, respectively. The kinetics of the system is investigated based on the mean-field theory. In the model of population-catalyzed birth of aseets, the long-time asymptotic behavior of the assets aggregate size distribution obeys the conventional or modified scaling form. In mutually catalyzed birth system, the asymptotic behaviors of population and assets obey the conventional scaling form in the case of η=λ =0, and they obey the modified scaling form in the case of η=0, λ=1. In the case of η = λ= 1, the total mass of population aggregates and that of asset aggregates both grow much faster than those in population-catalyzed birth of assets model, and they approaches to infinite values in finite time.

Background: Although many risk factors for mortalityof necrotizing enterocolitis (NEC) were investigated,most of them were obtained from preterm infants, andfew works focused on the prognostic risk factors in fullterminfants. This study aimed to identify risk factors anddevelop a prediction score model for mortality in fulltermneonates with ***: The risk factors were analyzed retrospectivelyby bivariate and multivariate logistic regression analysis in153 full-term neonates with NEC, who were hospitalizedin Children's Hospital of Chongqing Medical Universityfrom 2000 to 2013. A prediction score model was developedaccording to the regression coeffi cients of risk ***: The mortality of the infants was 19.6%(30/153). The non-survivors had a younger age of diagnosisand advanced stage of NEC (P<0.05). They had a higherprevalence of respiratory failure, intestinal perforation,peritonitis and other complications, compared with thesurvivors (P<0.05). On the day of diagnosis, the nonsurvivorswere more likely to have abnormal laboratoryindicators than survivors (P<0.05). Age at diagnosis [oddsratio (OR)=0.91, 95% confidence interval (CI)=0.836-0.99], respiratory failure (OR=2.76, 95% CI=1.10-6.92),and peritonitis (OR=26.36, 95% CI=7.52-173.92) hadsignificant independent contributions to death. A scoremodel predicting death was developed, and the area underthe receiver operating characteristic curve was 0.869 (95%CI=0.803-0.935). All infants with scores ≥8 ***: Younger age at diagnosis, peritonitis,and respiratory failure might be risk factors for themortality of full-term infants with NEC. Infants with apredictive score of 8 were at high risk for death.

Currently, deep drilling operates under extreme conditions of high temperature and high pressure,demanding more from subterranean power motors. The all-metal positive displacement motor, known for its robust performance, is a critical choice for such drilling. The dimensions of the PDM are crucial for its performance output. To enhance this, optimization of the motor's profile using a genetic algorithm has been undertaken. The design process begins with the computation of the initial stator and rotor curves based on the equations for a screw cycloid. These curves are then refined using the least squares method for a precise fit. Following this, the PDM's mathematical model is optimized, and motor friction is assessed. The genetic algorithm process involves encoding variations and managing crossovers to optimize objective functions, including the isometric radius coefficient, eccentricity distance parameter,overflow area, and maximum slip speed. This optimization yields the ideal profile parameters that enhance the motor's output. Comparative analyses of the initial and optimized output characteristics were conducted, focusing on the effects of the isometric radius coefficient and overflow area on the motor's performance. Results indicate that the optimized motor's overflow area increased by 6.9%, while its rotational speed reduced by 6.58%. The torque, as tested by Infocus, saw substantial improvements of38.8%. This optimization provides a theoretical foundation for improving the output characteristics of allmetal PDMs and supports the ongoing development and research of PDM technology.
