Introduction: Ca.a.a.d Va.a.a.e the most importa.t a.d well-studied virulence fa.tors found in Helicoba.ter pylori. The a.m of this work wa. to identify genes corresponding to H. pylori pa.hogenicity fa.tors in Bra.za.ille, Congo. Ma.eria. & Methods: a.cross-sectiona. study wa. ca.ried out from October 2013 to December 2016. Biopsy specimens were obta.ned from pa.ients scheduled for upper ga.trointestina. endoscopy in Bra.za.ille, Congo a.d were sent to the French Na.iona. reference Center for Ca.pyloba.ters a.d Helicoba.ters in Bordea.x, Fra.ce. H. pylori detection wa. conducted by rea.-time PCR using a.fuorescence resona.ce energy tra.sfer-melting curve a.a.ysis protocol. The identifica.ion of the genes encoding pa.hogenicity fa.tors wa. ca.ried out by conventiona. PCR using the a.propria.e primers for determina.ion of Ca.a.phosphoryla.ion motifs 1, 2, 3;a.d va.a., I a.d m regions: va.a.1, va.a.2, va.a.1a. va.a.1b. results: a.high preva.ence of H. pylori infection wa. reported (108/143;75.5%). In 92.2% (n = 71/77), the presence of P1, P2 a.d P3 Ca.a.phosphoryla.ion motifs wa. noted. Concerning va.a. va.a.1m1 wa. observed in 82% of the stra.ns (n = 59/72). va.a.1 wa. present in a.l stra.ns (n = 76). With rega.d to the distribution a.cording to the va.a.1 subtype, the ma.ority of the stra.ns (59/71;83%) were va.a.1b positive, a. compa.ed to va.a.1c (17/34, 33%). The va.a.1a.gene wa. a.sent in a.l of these pa.ients. Conclusion: The presence of genes a.socia.ed with severe ga.tric disea.es indica.es the importa.ce of H. pylori era.ica.ion in the prevention of these disea.es in Congo.

In this study, we developed a.genera. method to a.a.ytica.ly ta.kle a.kind of mova.le bounda.y problem from the viewpoint of energy va.ia.ion.

Switcha.le hydrophobic-hydrophilic la.er obta.ned onto porous a.umina.by pla.ma.enha.ced fluorina.ion

Conventiona. lithogra.hic printing processes using porous a.umina.for offset a.plica.ions genera.ly use "wet" routes. recently "dry" processes ha.e been developed which a.e ba.ed on a.hea.-induced hydrophilic/oleophilic conversion of one or more la.ers of the coa.ing so tha. a.stronger a.finity to-wa.ds ink or wa.er founta.n is crea.ed a. the exposed a.ea. with respect to the surfa.e of the unex-posed coa.ing. Trea.ments involving rf pla.ma.enha.ced fluorina.ion (PEF) constitute exceptiona. tools for modifying the surfa.e properties of ma.eria.s. Ma.y a.va.ta.es of these techniques ca. be indeed outlined, when compa.ed to more conventiona. methods: room-tempera.ure rea.tions, chemica. modi-fica.ions limited to surfa.e only without cha.ging the bulk properties, possible non-equilibrium rea.-tions. The influence of PEF trea.ments on porous a.umina.la.er used in printing pla.es ha. been tested with va.ious fluorina.ed ga.es (CF4, C3F8 a.d C4F8) a.d cha.a.terized by XPS. The hydrophobic prop-erties of the fluorina.ed la.er ha.e been deduced from conta.t a.gle mea.urements. Using C4F8 rf-PEF trea.ment, the outmost surfa.e of the hydrophilic a.umina.substra.e used for lithogra.hic printing is hydrophobized, or in other words, the hydrophilic substra.e is converted into a.support with hydro-phobic properties. Once being hydrophobized, the surfa.e la.er ma. be rendered hydrophilic using a.hea. pulse, thus giving rise to switcha.le hydrophobic-hydrophilic properties of the ma.eria..

a.Mode-Switching Motion Control System for rea.tive Intera.tion a.d Surfa.e Following Using Industria. Robots

引用

IEEE/Ca. Journa. of a.toma.ica.Sinica 2018年第3期5卷 670-682页

作者： Da.ia. Na.ha.inia.Pierre Pa.eur Robert La.a.ière School of Electrica. Engineering a.d Computer Science University of Ottawa

This work proposes a.sensor-ba.ed control system for fully a.toma.ed object detection a.d explora.ion(surfa.e following) with a.redunda.t industria. robot. The control system utilizes both offline a.d online tra.ectory pla.ning for rea.tive intera.tion with objects of different sha.es a.d color using RGBD vision a.d proximity/conta.t sensors feedba.k where no prior knowledge of the objects is a.a.la.le. The RGB-D sensor is used to collect ra. 3D informa.ion of the environment. The da.a.is then processed to segment a. object of interest in the scene. In order to completely explore the object, a.covera.e pa.h pla.ning technique is proposed using a.dyna.ic 3D occupa.cy grid method to genera.e a.prima.y(offline) tra.ectory. However, RGB-D sensors a.e very sensitive to lighting a.d provide only limited a.cura.y on the depth mea.urements. Therefore, the covera.e pa.h pla.ning is then further a.sisted by a.rea.-time a.a.tive pa.h pla.ning using a.fuzzy self-tuning proportiona. integra. deriva.ive(PID)controller. The la.ter a.lows the robot to dyna.ica.ly upda.e the 3D model by a.specia.ly designed instrumented complia.t wrist a.d a.a.t to the surfa.es it a.proa.hes or touches. a.modeswitching scheme is a.so proposed to efficiently integra.e a.d smoothly switch between the intera.tion modes under certa.n conditions. Experimenta. results using a.CRS-F3 ma.ipula.or equipped with a.custom-built complia.t wrist demonstra.e the fea.ibility a.d performa.ce of the proposed method.
