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.

作曲家利盖蒂长期以来与哲学家阿多诺保持着通信联系,而且利盖蒂对20世纪后半叶的新音乐发展也具有重要的参照作用,但这些方面一直被人们所忽视。作者在考证大量史料的基础上,以开放的“音乐现代主义”概念为前提,结合对《伟大的死亡》①等作品的分析与阐释,剖析了利盖蒂与阿多诺之间的理念关联,特别是阿多诺《困境》一文对利盖蒂的影响,重新审视了作曲家在现代主义中的地位与立场。本文最终认为,利盖蒂深受阿多诺的“否定性”与“非形象音乐”等理念的影响,以具有表现性与意象性的音乐瞬间来表达死亡等方式,瓦解了“保守”与“先锋”之间的二元对立,展现出“主观性”与“客观性”相结合的悖论美学。

Flow frictional characteristics of microencapsulated phase change material suspensions flowing through rectangular minichannels

引用

Science China(Technological Sciences) 2006年第4期49卷 445-456页

作者： Frank Dammel peter Stephan Chair of Technical Thermodynamics Darmstadt University of Technology Germany

An experimental investigation was conducted on the laminar flow frictional characteristics of suspensions with microencapsulated phase change material (MEPCM) in water flowing through rectangular copper minichannels. The MEPCM was provided at an average particle size of 4.97 μm, and was mixed with distilled water to form suspen- sions with various mass concentrations ranging from 0 to 20%. The experiment was per- formed to explore the effect of MEPCM mass concentration on friction factor and pressure drop in the minichannels. The Reynolds number ranged from 200 to 2000 to provide laminar and transitional flows. It was found that the experimental data for the suspensions with 0 and 5% concentration agree well with the existing theoretical data for an incom- pressible, fully developed, laminar Newtonian flow. For the suspensions with mass con- centrations higher than 10%, there is an obvious increase in friction factor and pressure drop in comparison with laminar Newtonian flow.

PARALLEL STOCHASTIC NEWTON METHOD

引用

Journal of Computational Mathematics 2018年第3期36卷 404-425页

作者： Mojmir Mutny peter Richtarik Department of Informatics ETH Zurich Zurich Switzerland School of Mathematics University of Edinburgh Edinburgh ETH9 3FD UK Computer Electrical and Mathematical Sciences & Engineering Department KA UST Saudi Arabia

We propose a parallel stochastic Newton method （PSN） for minimizing unconstrained smooth convex functions. We analyze the method in the strongly convex case, and give conditions under which acceleration can be expected when compared to its serial counterpart. We show how PSN can be applied to the large quadratic function minimization in general, and empirical risk minimization problems. We demonstrate the practical efficiency of the method through numerical experiments and models of simple matrix classes.

Operational Wave Now- and Forecast in the German Bight as a Basis for the Assessment of Wave-Induced Hydrodynamic Loads on Coastal Dikes

引用

Journal of Ocean University of China 2017年第6期16卷 991-997页

作者： DREIER Norman FROHLE peter Institute of River and Coastal Engineering Hamburg University of Technology Hamburg Germany

The knowledge of the wave-induced hydrodynamic loads on coastal dikes including their temporal and spatial resolution on the dike in combination with actual water levels is of crucial importance of any risk-based early warning system. As a basis for the assessment of the wave-induced hydrodynamic loads, an operational wave now-and forecast system is set up that consists of i) available field measurements from the federal and local authorities and ii) data from numerical simulation of waves in the German Bight using the SWAN wave model. In this study, results of the hindcast of deep water wave conditions during the winter storm on 5–6 December, 2013(German name ‘Xaver') are shown and compared with available measurements. Moreover field measurements of wave run-up from the local authorities at a sea dike on the German North Sea Island of Pellworm are presented and compared against calculated wave run-up using the Eur Otop(2016) approach.

Links between global CO_2 variability and climate anomalies of biomes

引用

Science China Earth Sciences 2008年第5期51卷 740-747页

作者： peter S. BAKWIN School of Earth and Environmental Sciences Queens College City University of New York New York 11367 USA

The global rate of fossil fuel combustion continues to rise, but the amount of CO2 accumulating in the atmosphere has not increased accordingly. The causes for this discrepancy are widely debated. Par- ticularly, the location and drivers for the interannual variability of atmospheric CO2 are highly uncertain. Here we examine links between global atmospheric CO2 growth rate (CGR) and the climate anomalies of biomes based on (1986―1995) global climate data of ten years and accompanying satellite data sets. Our results show that four biomes, the tropical rainforest, tropical savanna, C4 grassland and boreal forest, and their responses to climate anomalies, are the major climate-sensitive CO2 sinks/sources that control the CGR. The nature and magnitude by which these biomes respond to climate anomalies are generally not the same. However, one common influence did emerge from our analysis; the ex- tremely high CGR observed for the one extreme El Nio year was caused by the response of the tropical biomes (rainforest, savanna and C4 grassland) to temperature.
