s.rface-enhanced Raman s.attering （s.Rs. has.emerged as.an excellent analytical tool for the effective detection and fingerprint identification of various.chemicals. Recently, s.gnificant progres. has.been made in the fabrication of s.Rs.active s.bs.rates.us.ng s.mple, inexpens.ve, and affordable methods. The full potential of univers.l s.Rs.diagnos.ics.will likely be realized with the development of approaches.and devices.capable of effectively detecting analytes.on various.s.rfaces.as.well as.in multicomponent media. In addition, the combination of implantable or wearable s.Rs.active s.bs.rates.and remote portable devices.enables.real-time diagnos.ics.that ideally fit the concept of pers.nalized medicine. In this.paper, we s.mmarize recent achievements.in fabricating flexible s.Rs.s.bs.rates.made of cellulos. paper, polymer membranes. and textile fibrous.films. Emphas.s.is.placed on the in-s.tu extraction and detection of various.chemicals.in real-world s.rfaces.and complex media us.ng flexible nanofibrous.s.Rs.platforms. The potential s.Rs.applications.and future pers.ectives.in on-s.te diagnos.ics.are als. dis.us.ed.

Let G be a finite group of Lie type E6 over Fq (adjoint or s.mply connected) and W be the Weyl group of G. We des.ribe maximal tori T s.ch that T has.a complement in its.algebraic normalizer N(G, T). It is.well known that for each maximal torus.T of G there exis.s.an element w ∈ W s.ch that N(G, T )/T ■ CW(w). When T does.not have a complement is.morphic to CW(w), we s.ow that w has.a lift in N(G, T) of the s.me order.

A model intercomparis.n in terms.of s.rface air temperature annual cycle amplitude-phas. characteris.ics.(s.T AC APC) is.performed. The models.included in the intercomparis.n belong to two groups. five atmos.heric models.with pres.ribed s.a s.rface temperature and s.a ice cover and four coupled models.forced by the atmos.heric abundances.of anthropogenic cons.ituents.(in total s.x coupled model s.mulations.. Over land, the models. s.mulating higher than obs.rved time averaged s.T, als. tend to s.mulate s.aller than obs.rved amplitude of its.annual and s.miannual harmonics.and (outs.de the Tropics. later-than-obs.rved s.ring and autumn moments. The models.with larger (s.aller) time averaged amplitudes.of annual and s.miannual harmonics.als. tend to s.mulate larger (s.aller) interannual s.andard deviations. Over the oceans. the coupled models.with larger interannual s.andard deviations.of annual mean s.T tend to s.mulate larger interannual s.andard deviations.of both annual and s.miannual s.T harmonics.amplitudes. Mos. model errors.are located in the belts.60°–70°N and 60°–70°s.and over Antarctica. Thes. errors.are larger for thos. coupled models.which do not employ dynamical modules.for s.a ice. No s.s.ematic differences.are found in the s.mulated time averaged fields.of the s.rface air temperature annual cycle characteris.ics.for atmos.heric models.on one hand and for the coupled models.on the other. But the coupled models.generally s.mulate interannual variability of s.T AC APC better than the atmos.heric models.(which tend to underes.imate it). For the coupled models. the res.lts.are not very s.ns.tive to the choice of the particular s.enario of anthropogenic forcing.
