关键词： 青鱼   养殖密度   鱼粉   生长   免疫   应激  

摘要： 为研究鱼粉水平和养殖密度对青鱼(Mylopharyngodon plceus)幼鱼生长及免疫的影响,试验采用鱼粉水平(10%、20%)×养殖密度(50、100和200尾/箱)的双因素设计,将青鱼幼鱼(2.50±0.02)g分为L50、L100、L200、H50、H100和H2006组,每组3个重复,养殖试验在水库网箱(1.5 m×1.5 m×1.5 m)中进行。结果显示:(1)生长性能:实验中期(第8周),青鱼的增重率随养殖密度的增加呈先上升后下降趋势,且H200组的青鱼增重率在养殖中期与L200组相比有提高的趋势,但差异不显著(P>0.05),在实验后期(第16周)显著低于L200组(P<0.05);L200的存活率低于L50组(P>0.05),养殖密度和鱼粉水平对青鱼存活率与增重率有交互效应(P<0.05)。(2)免疫应激指标:在实验中期,低鱼粉组青鱼的溶菌酶(LSZ)、血糖(GLU)随密度的升高先下降后上升,肠道分泌性免疫球蛋白A(S-IgA)有提高的趋势;H200组的LSZ、补体4(C4)、免疫球蛋白M(IgM)、S-IgA和皮质醇(COR)含量均高于L200组,GLU低于L200组(P>0.05)。在实验后期,高低鱼粉组的C4随密度的增加均呈下降后上升的趋势(P>0.05)。H200组的IgM和COR含量均高于L200组,GLU低于L200组(P>0.05)。综上所述,在本实验条件下,实验中期高密度养殖会使青鱼幼鱼生长性能有降低趋势,对机体免疫、抗应激能力产生负面影响,增加鱼粉水平有一定改善作用,实验后期高密度养殖降低了低鱼粉饲料组青鱼的存活率,提高鱼粉水平对高密度组青鱼生长性能和免疫功能无改善作用。

摘要： The decomposition-based evolutionary algorithm has become an increasingly popular choice for posterior multiobjective optimization. Facing the challenges of an increasing number of objectives, many techniques have been developed which help to balance the convergence and diversity. Nevertheless, according to a recent study by Ishibuchi et al., due to the predefined search directions toward the ideal point, their performance strongly depends on the Pareto front (PF) shapes, especially the orientation of the PFs. To balance the convergence and diversity for decomposition-based methods and to alleviate their performance dependence on the orientation of the PFs, this paper develops an adversarial decomposition method for many-objective optimization, which leverages the complementary characteristics of different subproblem formulations within a single paradigm. More specifically, two populations are co-evolved by two subproblem formulations with different contours and adversarial search directions. To avoid allocating redundant computational resources to the same region of the PF, the two populations are matched into one-to-one solution pairs according to their working regions upon the PF. Each solution pair can at most contribute one principal mating parent during the mating selection process. When comparing nine state-of-the-art many-objective optimizers, we have witnessed the competitive performance of our proposed algorithm on 130 many-objective test problems with various characteristics, including regular and inverted PFs.

关键词： Early life adversity   life course   stress   dual risk   accumulation of risk  

摘要： A large body of evidence has shown that stress throughout life is associated with health trajectories, but the combination of adverse experiences at different stages of the life course is not yet well understood. This study examines the interactions between childhood adversity, adulthood adversity, and adult physical and mental health. Using data from The Childhood Retrospective Circumstances Study (CRCS) supplement to the Panel Study of Income Dynamics (PSID), we created indices of early life adversity (EAI) and adult adversity (AAI). We used logistic regression to examine the effects of EAI and AAI, adjusting for age, sex, race/ethnicity, health behaviors, and childhood health as covariates in all models. We repeated this analysis for the outcomes of fair/poor health, two or more chronic conditions, and psychological distress in adulthood. For all the three outcomes, our findings suggest increasing salience of adult adversity among those who experienced higher levels of early adversity. Individuals with high EAI and high AAI exhibited the highest odds of fair/poor health (OR = 5.71), chronic conditions (OR = 3.06), and psychological distress (OR = 13.08) compared to those with low EAI and low AAI. These findings are consistent with the accumulation of risk or dual risk model of stress and health. Adversity in childhood amplifies the health risks associated with stress in adulthood for multiple health outcomes.

摘要： Speech recognition has become one of the most significant parts of human-computer interaction due to emergence of new technologies such as smartphone, smart watch and many modern technologies, therefore the need of an ASR for local languages is felt. The basic aim of this paper is to develop an isolated digits recognition for Pashto language, using deep CNN. The database of Pashto digits from 0 to 9 with 50 utterance for each digits is used. Twenty MFCC features extracted for each isolated digit and fed as input to CNN. The network has been used for the proposed system is deep up to 4 convolutional layers, followed by ReLU and max-pooling layers. The network has been trained on the 50% of data and the rest of the data was used for testing. The total average of 84.17% accuracy was achieved for testing which show 7.32% better performance as compared to existing similar works.

摘要： Permutation polynomials (PPs) and their inverses have applications in cryptography, coding theory and combinatorial design theory. In this paper, we make a brief summary of the inverses of PPs of finite fields, and give the inverses of all PPs of degree <= 6 over finite fields $\mathbb {F}_{q}$ for all $q$ and the inverses of all PPs of degree 7 over $\mathbb {F}_{2<^>{n}}$ . The explicit inverse of a class of fifth degree PPs is the main result, which is obtained by using Lucas' theorem, some congruences of binomial coefficients, and a known formula for the inverses of PPs of finite fields.

关键词： Mongolian Mind-Body Interactive   Psychotherapy   Esophageal cancer   Quality of life   EORTC QLQ-OES 18   QLICP-OES  

摘要： Esophageal cancer is a major public health issue in China. Mongolian MindBody Interactive Psychotherapy (MMIP) is a new psychotherapy that combines modern psychology with traditional Mongolian medicine. Previous cases have shown better quality of life (QoL) after MMIP in patients with cancer and other diseases. This study aimed to shed light on the effect of MMIP on the quality of life of patients in Inner Mongolia. A total of 21 patients diagnosed with esophageal cancer were studied. QoL assessment was performed using the two questionnaires of EORTC QLQ-OES 18 and QLICP-OES. The results showed that MMIP had statistical significant improvement on body function, psychological function, common symptoms, and side effects, such as reflux. As alternative and complementary medicine, MMIP could help esophageal cancer patients experience better QoL. Further large-scale studies are required to determine the impact of MMIP for QoL in patients undergoing surgery or chemotherapy for esophageal cancer.
