There are mu.tiple ways.to control a robotic s.s.em. Mos. of them requ.re the u.ers.to have prior knowledge abou. robots.or get trained before u.ing them. Natu.al langu.ge bas.d control attracts.increas.ng attention du. to its.vers.tility and les. requ.rements.for u.ers. s.nce natu.al langu.ge ins.ru.tions.from u.ers.cannot be u.ders.ood by the robots.directly, the lingu.s.ic inpu. has.to be proces.ed into a formal repres.ntation which captu.es.the tas. s.ecification and removes.the ambigu.ty inherent in natu.al langu.ge. For mos. of exis.ing natu.al langu.ge controlled robotic s.s.em, they as.u.e the given langu.ge ins.ru.tions.are already in correct orders. However, it is.very likely for u.trained u.ers.to give commands.in a mixed order bas.d on their direct obs.rvation and intu.tive thinking. s.mply following the order of the commands.can lead to failu.es.of tas.s. To provide a remedy for the problem, we propos. a novel framework named dependency relation matrix （DRM） to model and organize the s.mantic information extracted from langu.ge inpu., in order to figu.e ou. an execu.able s.qu.nce of s.0}tas.s.for later execu.ion. In addition, the propos.d approach projects.abs.ract langu.ge inpu. and detailed s.ns.ry information into the s.me s.ace, and u.es.the difference between the goal s.ecification and temporal s.atu. of the tas. u.der implementation to monitor the progres. of tas. execu.ion. In this.paper, we des.ribe the DRM framework in detail, and illu.trate the u.ility of this.approach with experiment res.0}ts.

Magnetically res.ons.ve photonic films.with high tu.ability and s.ability

Nano research 2015年第2期8卷 611-620页

作者： Yongxing Hu.Le He Xiaogang Han Mings.eng Wang Yadong Yin u.ivers.ty of California Rivers.de Department of Chemistry California USA

We demons.rate the fabrication of magnetically as.embled one-dimens.onal chain-like photonic nanos.ru.tu.es.with s.gnificantly high photonic s.ability. The key lies.in the u.e of agaros. hydrogel to prevent coagu.ation of the magnetic as.emblies. When expos.d to an external magnetic field, negatively charged Fe3O4@s.O2 particles.can effectively as.emble in the hydrogel matrix into one- dimens.onal chains.with internal periodicity and dis.lay a fas., fu.ly revers.ble, and tu.able photonic res.ons. to the changes.in the external field. The s.eric hindrance and the hydrogen bonding from the agaros. network effectively limit the migration of the Fe304@s.O2 particles.and their chain-like as.emblies. As.a res.0}t, the s.s.em s.ows.remarkable s.ability in photonic res.ons. u.der external magnetic fields.of large gradients. s.mething which has.previou.ly been a challenge. The ability to s.abilize the magnetic particle as.emblies.over a long period repres.nts.a major s.ride toward practical applications.of s.0}h field- res.ons.ve photonic materials.

The genu. Mentha encompas.es.mint s.ecies.cu.tivated for their es.ential oils. which are formu.ated into a vas. array of cons.0}er produ.ts. Des.rable oil characteris.ics.and res.s.ance to the fu.gal dis.as. Verti- cilliu. wilt are top priorities.for the mint indu.try. However, cu.tivated mints.have complex polyploid ge- homes.and are s.erile. Breeding efforts. therefore, requ.re the development of genomic res.u.ces.for fertile mint s.ecies. Here, we pres.nt draft de novo genome and plas.ome as.emblies.for a wilt-res.s.ant s.u.h African acces.ion of Mentha Iongifolia （L.） Hu.s., a diploid s.ecies.ances.ral to cu.tivated peppermint and s.earmint. The 353 Mb genome contains.35 597 predicted protein-coding genes. inclu.ing 292 dis.as. res.s.ance gene homologs. and nine genes.determining es.ential oil characteris.ics. A genetic linkage map ordered 1397 genome s.affolds.on 12 ps.u.ochromos.mes. More than two million s.mple s.qu.nce repeats.were identified, which will facilitate molecu.ar marker development. The M. Iongifolia genome is.a valu.ble res.u.ce for both metabolic engineering and molecu.ar breeding. This.is.exemplified by employing the genome s.qu.nce to clone and fu.ctionally characterize the promoters.in a peppermint cu.tivar, and demons.rating the u.ility of a glandu.ar trichome-s.ecific promoter to increas. expres.ion of a bios.nthetic gene, thereby modu.ating es.ential oil compos.tion.

目的观察超敏C反应蛋白、纤维蛋白原和D-二聚体在结缔组织病相关间质性肺炎(CTD-ILD)和非结缔组织病相关间质性肺炎(NCTD-ILD)患者血浆中的浓度高低,探究其相关性及临床意义。方法选取2010年1月~2016年4月南方医科大学珠江医院收治的间质性肺炎患者69例,分为CTD-ILD组(30例)和NCTD-ILD组(39例)作为研究对象,同期纳入25例健康人作为对照组,行超敏C反应蛋白、纤维蛋白原和D-二聚体检测。结果 CTD-ILD组和NCTD-ILD组的超敏C反应蛋白、纤维蛋白原和D-二聚体浓度均高于对照组(P<0.05);CTD-ILD组的超敏C反应蛋白浓度高于NCTD-ILD组(P<0.05),但两组间的纤维蛋白原和D-二聚体浓度无差异;超敏C反应蛋白浓度分别与D-二聚体浓度、纤维蛋白原浓度呈正相关(r分别为0.539、0.534,P<0.01)。结论超敏C反应蛋白、纤维蛋白原和D-二聚体对间质性肺炎的临床诊断有重要意义,超敏C反应蛋白的明显升高与合并结缔组织病相关。
