Robust fa.lt detection a.d dia.nosis for uncerta.n nonlinea. systems

This pa.er considers robust fa.lt detection a.d dia.nosis for input uncerta.n nonlinea. systems. It proposes a.multi-objective fa.lt detection criterion so tha. the fa.lt residua. is sensitive to the fa.lt but insensitive to the uncerta.nty a. much a. possible. Then the pa.er solves the proposed criterion by ma.imizing the sma.lest singula. va.ue of the tra.sforma.ion from fa.lts to fa.lt detection residua.s while minimizing the la.gest singula. va.ue of the tra.sforma.ion from input uncerta.nty to the fa.lt detection residua.s. This method is a.plied to a. a.rcra.t which ha. a.fa.lt in the left eleva.or or rudder. The simula.ion results show the proposed method ca. detect the control surfa.e fa.lures ra.idly a.d efficiently.

Tumor microenvironment （TME） comprising cellula. a.d non-cellula. components is a.ma.or source of ca.cer ha.lma.ks. Nota.ly, a.giogenesis responsible for norma. physiologica. remodeling process ca. otherwise ha.ness vessel a.norma.ities during tumorigenesis eliciting severe thera.eutic inefficiency. Currently, FDa.a.proved a.tia.giogenic drugs ha.e only shown modest clinica. success owing to tumor hypoxia. a.tia.giogenic thera.eutic resista.ce, a.d limited knowledge in understa.ding TME. In order to overcome these limita.ions, ta.geting a.giogenesis combined with immtmosuppressive TME could offer potentia. thera.eutic opportunities. Indeed, these thera.eutic a.proa.hes ca. be further revisited with the a.vent of na.o- technology tha. ca. ta.get the key cellula. components of TME a.d tumor cells more precisely. Synergetic ta.geting without eliciting systemic toxicity a.hieved by integra.ion of a.tia.giogenic a.d immunothera.y in a.single na.opla.form is vita. for thera.eutic success. In this review, we will discuss the most promising na.otechnologica. a.va.cements oriented to modula.e the immunosuppressive TME in a.socia.ion with a.tia.giogenic thera.y tha. ha. ga.ned immense popula.ity in ca.cer trea.ment.
