The introduction of invasive insect pests across national borders has become a major concern in crop production. Accordingly, national plant protection organizations are challenge to reinforce their monitoring strategies, which are hampered by the weight and size of inspection equipment, as well as the taxonomic extensiveness of interrupted species. Moreover, some insect pests that impede farmer productivity and profitability are difficult for researchers to address on time due to a lack of appropriate plant protection measures. Farmers’ reliance on synthetic pesticides and biocontrol agents has resulted in major economic and environmental ramifications. DNA barcoding is a novel technology that has the potential to improve Integrated Pest Management decision-making, which is dependent on the ability to correctly identify pest and beneficial organisms. This is due to some natural traits such as phenology or pesticide susceptibility browbeaten by IPM strategies to avert pest establishment. Specifically, Deoxyribonucleic acid (DNA) sequence information was applied effectively for the identification of some micro-organisms. This technology, DNA barcoding, allows for the identification of insect species by using short, standardized gene sequences. DNA barcoding is basically based on repeatable and accessible technique that allows for the mechanisation or automation of species discrimination. This technique bridges the taxonomic bio-security gap and meets the International Plant Protection Convention diagnostic standards for insect identification. This review therefore discusses DNA barcoding as a technique for insect pests’ identification and its potential application for crop protection.

在选区激光熔融加工过程中,包含大量加工状态和工艺参数信息的熔池图像存在噪声污染、熔池边缘模糊等问题,因此提高熔池图像的分辨率对监测熔池状态具有重要意义。提出一种基于深度学习的熔池图像超分辨率重建算法,用于提取低分辨率熔池图像的浅层特征和深层特征并学习低分辨率图像到高分辨率图像之间的映射关系,使用亚像素卷积上采样完成熔池图像重建过程。分别对采集的高分辨率、退化后的低分辨率、重建的高分辨率熔池图像进行图像预处理和提取熔池形貌特征,以采集的高分辨率熔池图像的形貌特征为标签计算熔池特征误差率。结果显示,重建的熔池图像不仅可以提高分辨率,还大幅度降低了熔池形貌特征提取的误差率,为选区激光熔融成型过程监测和精准调控加工工艺参数提供了保证。

Social biology of rodents

引用

Integrative Zoology 2007年第4期2卷 193-204页

作者： jerry O.WOLFF Department of Biology St.Cloud State UniversitySt.CloudMinnesotaUSA

Herein, I summarize some basic components of rodent social biology. The material in this paper is summarized andcondensed from a recent book “Rodent Societies: An Ecological and Evolutionary Perspective” edited by J. *** and P. W. Sherman (2007). I describe the four basic spacing patterns and illustrate how female territoriality isa function of offspring defense and male mating tactics are a function of female defensibility. The vulnerability ofyoung to infanticide shapes female spacing and mating behavior. Food does not appear to be a defensible resourcefor rodents, except for those species that larder hoard nonperishable items such as seeds. Philopatry and theformation of kin groups result in genetic sub-structuring of the population, which in turn affects effectivepopulation size and genetic diversity. Dispersal is male biased and typically involves emigration from the maternalsite to avoid female relatives and to seek unrelated mates. Scent marking is a major form of communication and isused in reproductive competition and to assess prospective mates, but it is also eavesdropped by predators to locateprey. Females do not appear to alter the sex ratio of litters in response to maternal condition but among arvicolinerodents daughters appear to be favored in spring and sons in autumn. Rodents are relatively monomorphic;however, females tend to be larger than males in the smallest species and smaller in the larger species. Predationrisk results from an interaction among foraging time and vulnerability and in turn affects behavioral and life historycharacteristics.

The Ideology of ＂Swings between Reality and Illusion＂ in Mo Yan＇s Pow!

引用

Frontiers of Literary Studies in China-Selected Publications from Chinese Universities 2017年第4期11卷 688-738页

作者： jerry XIE The School of Foreign Languages Lanzhou Jiaotong University Lanzhou 730070 China

According to Angelica Duran and Yuhan Huang, Mo Yan＇s ＂artistic works＂ are ＂towering within the literatures of the world.＂ His novel Si shi yi pao （Pow!, 2o12） offers one of the clearest recent examples of what Shelley W. Chan calls Mo＇s ＂postmodern playfulness.＂ In his afterword to Pow! Mo says that the story ＂gives way to an improvisation that swings between reality and illusion,＂ thus suggesting the notion of ＂hallucinatory realism＂ as a ＂blending＂ or ＂merging＂ of the illusory and the real. This article examines the ideology--that is, the class politics of consciousness--of this swingy postmodern storytelling, taking a critical view of Mo＇s playfully bold assertion：＂I＇ve always taken pride in my lack of ideology, especially when I＇m writing.＂ I argue that the swinginess of ＂imagination＂ in Pow! embodies what Marx calls a ＂happy confusion＂ that （re）articulates the ＂post＂-class doctrine of ＂combine two into one.＂

An evolutionary perspective on conflict and compensation in physiological and functional traits

引用

Current Zoology 2014年第6期60卷 755-767页

作者： jerry F. HUSAK Simon R LAILVAUX Department of Biology University of St. Thomas 2115 Summit Avenue St Paul MN 55105 USA Department of Biological Sciences University of New Orleans 2000 Lakeshore Drive New Orleans LA 70148 USA

Physiological and functional traits, especially those related to behavior and whole-organism performance capacities, are subject to a variety of both parallel and opposing natural and sexual selection pressures. These selection pressures show considerable interspeciflc variation, shaping contemporary behavioral and functional diversity, but the form and intensity of selection on physiological and functional traits can also vary intraspecifically. The same suites of traits can experience quite different se- lection pressures, depending on the sex or age of a given individual, as well as the presence and nature of alternative reproductive strategies and tactics. These inter- and intra-locus genetic conflicts have potentially important consequences for the evolutionary trajectories of traits subject to them. Consequently, any intraspecific conflicts which could displace traits from their selective op- tima in certain classes of individuals relative to others are expected to result in selection for mechanisms to compensate for devia- tion from those optima. Such conflicts include interlocus sexual conflict, intralocus sexual conflict, and interacting phenotypes, as well as conflict within a sex. In this paper, we consider the evidence for, and implications of, such conflicts for physiological and functional traits in diverse taxa, including both vertebrates and invertebrates, and evaluate the various mechanisms, ranging from behavioral and mechanical to energetic and genetic, enabling compensation. We also discuss how pre- and post-mating conflicts, as well as interacting phenotypes, might affect the evolution of behavior and physiological and functional traits. Investigators that seek to understand the links among behavior, morphology, physiology, and function should consider such conflicts.

Method for prevention and control of spontaneous combustion of coal seam and its application in mining field

引用

International Journal of Mining Science and Technology 2017年第5期27卷 839-846页

作者： Wei Lu Ying-Jiazi Cao jerry C.Tien College of Mining and Safety Engineering Shandong University of Science & Technology Department of Civil Engineering Monash University

Spontaneous combustion of coal seam has been and continues to be a big problem in coal mines. It could pose great threat to the safety of the whole mine and all miners, especially when it occurs in or nearby coal mines. Besides, environment of area surrounded mines during combustion can be threatened where large amount of toxic gases including CO_2, CO, SO_2 and H_2S can be leased by fire in mine. Hence, it is important and significant for scholars to study the controlling and preventing of the coal seam fire. In this paper, the complicated reasons for the occurrence and development of spontaneous combustion in coal seam are analysed and different models under various air leakage situations are built as well. Based on the model and approximately calculation, the difficulty of fire extinguishment in coal seam is pointed out as the difficulty and poor effect to remove the large amount of heat released. Detailed measurements about backfilling and case analyses are also provided on the basis of the recent ten years' practice of controlling spontaneous combustion in coal seams in China. A technical fire prevention and control method has been concluded as five steps including detection, prevention, sealing, injection and pressure adjustment. However, various backfill materials require different application and environmental factors, so in this paper, analyses and discussion about the effect and engineering application of prevention of spontaneous combustion are provided according to different backfilling technologies and methods. Once the aforementioned fire prevention can be widely applied and regulated in mines, green mining will be achievable concerning mine fire prevention and control.
