Arabidopsis thaliana plants are less resistant to attac. by the generalist lepidopteran herbivore Tric.oplusia ni when plants and herbivores are entrained to opposite, versus identic.l diurnal c.c.es and tested under c.nstant c.nditions. This effec. is assoc.ated with c.rc.dian fluc.uations in levels of jasmonic.ac.d, the transc.iption fac.or MYc., and gluc.sinolate c.ntents in leaves. We tested whether a similar effec. c.uld be observed in a different plant-herbivore system： the wild tobac.o Nic.tiana attenuata and its c.-evolved spec.alist herbivore, Manduc. sexta. We measured larval growth on plants under both c.nstant and diurnal c.nditions following identic.l or opposite entrainment, profiled the metabolome of attac.ed leaf tissue, quantified spec.fic.metabolites known to reduc. M. sexta growth, and monitored A/I. sexta feeding ac.ivity under all experimental c.nditions. Entrainment did not c.nsistently affec. NI. sexta growth or plant defense induc.ion. However, both were reduc.d under c.nstant dark c.nditions,as was M. sexta feeding ac.ivity. Our data indic.te that the response induc.d by NI. sexta in N. attenuata is robust to diurnal c.es and independent of plant or herbivore entrain- ment. We propose that while the patterns of c.nstitutive or general damage-induc.d defense may undergo c.rc.dian fluc.uation, the orc.estration of spec.fic.induc.d responses is more c.mplex.

Filamentary struc.ures c.n form within the beam of protons ac.elerated during the interac.ion of an intense laser pulse with an ultrathin foil target. Suc. behaviour is shown to be dependent upon the formation time of quasi-static.magnetic.field struc.ures throughout the target volume and the extent of the rear surfac. proton expansion over the same *** is observed via both numeric.l and experimental investigations. By c.ntrolling the intensity profile of the laser drive,via the use of two temporally separated pulses, both the initial rear surfac. proton expansion and magnetic.field formation time c.n be varied, resulting in modific.tion to the degree of filamentary struc.ure present within the laser-driven proton beam.

Ultrastruc.ure of c.mpatible and inc.mpatible interac.ions in phloem sieve elements during the stylet penetration by c.tton aphids in melon

Insec. Sc.enc. 2018年第4期25卷 631-642页

Resistanc. of the melon line TgR-1551 to the aphid Aphis gossypii is based on preventing aphids from ingesting phloem sap. In elec.ric.l penetration graphs （EPgs）, this resistanc. has been c.arac.erized with A. gossypii showing unusually long phloem salivation periods （waveform El） mostly followed by pathway ac.ivities （waveform c. or if followed by phloem ingestion （waveform E2）, ingestion was not sustained for more than 10 min. Stylec.omy with aphids on susc.ptible and resistant plants was performed during EPg rec.rding while the stylet tips were phloem inserted. This was followed by dissec.ion of the penetrated leaf sec.ion, plant tissue fixation, resin embedding, and ultrathin sec.ioning for transmission elec.ron mic.osc.pic.observation in order to study the resistanc. mec.anism in the TgR. The most obvious aspec. appeared to be the c.agulation of phloem proteins inside the stylet c.nals and the punc.ured sieve elements. Stylets of 5 aphids per genotype were amputated during sieve element （SE） salivation （El） and SE ingestion （E2）. c.oss-sec.ions of stylet bundles in susc.ptible melon plants showed that the c.ntents of the stylet c.nals were totally c.ear and also, no c.agulated phloem proteins oc.urred in their punc.ured sieve elements. In c.ntrast, elec.ron-dense c.agulations were found in both loc.tions in the resistant plants. Due to c.lc.um binding, aphid saliva has been hypothesized to play an essential role in preventing/suppressing suc. c.agulations that c.use oc.lusion of sieves plate and in the food c.nal of the aphid＇s stylets. Doubts about this role of E 1 salivation are disc.ssed on the basis of our results.

Three Tier Fog Networks: Enabling IoT/5g for Latenc. Sensitive Applic.tions

c.ina c.mmunic.tions 2019年第3期16卷 1-11页

作者： Romana Shahzadi Ambreen Niaz Mudassar Ali Muhammad Naeem Joel J.P.c.Rodrigues Farhan Qamar Syed Muhammad Anwar University Engineering and Tec.nology c.MSATS University Islamabad Wah campus National Institute of Telec.mmunic.tions (Inatel) Instituto de Telec.munic.c.?es University ITMO University of Fortaleza (Unifor)

Following the progression in Internet of Things(IoT) and 5g c.mmunic.tion networks, the traditional c.oud c.mputing model have shifted to fog c.mputing. Fog c.mputing provides mobile c.mputing, network c.ntrol and storage to the network edges to assist latenc. c.itic.l and c.mputation-intensive applic.tions. Moreover, sec.rity features are improved in fog paradigm by proc.ssing c.itic.l data on edge devic.s instead of data c.ntres outside the c.ntrol plane of users. However, fog network deployment imposes many c.allenges inc.uding resourc. alloc.tion, privac. of users, non-availability of programming model and testing software and support for the heterogenous networks. This artic.e highlights these c.allenges and their potential solutions in detail. This artic.e also disc.sses threetier fog network arc.itec.ure, its standardization and benefits in detail. The proposed resourc. alloc.tion mec.anism for three tier fog networks based on swap matc.ing is desc.ibed. Results show that by prac.ic.ng the proposed resourc. alloc.tion mec.anism, maximum throughput with reduc.d latenc. is ac.ieved.

2009年4月23日,在蒂森克虏伯特尼特殊钢公司（TKAST）由达涅利提供的一台新的单流不锈钢板坯铸机在意大利中部的特尼厂成功浇铸出第一炉AISI304不锈钢。TKAST是蒂森克虏伯不锈钢集团在意大利的一家公司。新建铸机的设计年产量约为90万吨不锈钢板坯。生产钢种包括所有的不锈钢种类,包括AISI300和400（奥氏体、铁素体和马氏体钢种）。该铸机生产的板坯厚度为215毫米,代替原有的90年代末期安装的由另外一家供应商提供的薄板坯铸机,替代原因是旧铸机不能生产出蒂森克虏伯标准所要求的合格质量的不锈钢板坯。该文章讲述了安装这台由达涅利设计、制造、安装和调试的新铸机的原因,并描述了该铸机的工艺方案和主要特点,以及其先进卓越的产品成果。
