Recently, a tunable fiber Bragg grating(FBG) was.develop.d by us.ng s.res.-res.0}ns.ve colloidal crys.als. In this.p.p.r, we have s.mulated the ap.lication of thes. nanop.rticles.into the s.p.r-s.ructured fiber Bragg grating(s.FBG) written with p.rfect s.quences.derived from a s.ort maximal-length s.quence. A tunable s.FBG will be available to overcome the p.ohibitive temp.rature variation of the op.ical codecs. Nevertheles.,we p.es.nted a method to imp.ement coherent time s.0}eading op.ical code-divis.on multip.e-acces.(OCDMA) where a unique code(or p.rfect s.quence) can be reus.d and mixed with different wavelengths.to obtain a tunable wavelength-divis.on multip.exing(WDM)s.s.em. In order to maximize the binary throughp.t, we have s.lected a unique s.ort maximal-length s.quence comp.s.d of 7 chip. that can be tuned with 7 different op.ical wavelengths. We found thous.nds.of different tunable combinations.that p.es.nted p.wer contras. ratios.p.C) higher than 12 dB. When a WDM-OCDMA s.s.em us.d 2 different combinations.s.multaneous.y, the p.rfect binary detection with error correction codes.was.achieved s.cces.fully. The tunable s.FBG with colloidal crys.als.will be a s.mp.e and good alternative choice for fiber-to-the-home(FTTH) communications.

Tetragonis.a angus.ula is.one of the mos. wides.0}ead s.ingles. bees.in the Neotrop.cs. This.s.0}cies.s.arms.frequently and is.extremely s.cces.ful in urban envi- ronments. In addition, it is.one of the mos. p.p.lar s.ingles. bee s.0}cies.for beekeep.ng in Latin America, s. nes. trans.0}rtation and trading is.common. Nes. trans.0}rtation can change the genetic s.ructure of the hos. p.p.lation, reducing inbreeding and increas.ng homogenization. Here, we evaluate the genetic s.ructure of 17 geograp.ic p.p.lations.of T. angus.ula in s.uthern Brazil to quantify the level of genetic differentiation between p.p.lations. Analys.s.were conducted on p.rtially s.quenced mitochondrial genes.and 11 micros.tellite loci of 1002 workers.from 457 s.tes.dis.ributed on the mainland and on 3 is.ands. Our res.lts.s.ow that T. angus.ula p.p.lations.are highly differentiated as.demon- s.rated by mitochondrial DNA （mtDNA） and micros.tellite markers. Of 73 hap.otyp.s. 67 were p.p.lation-s.0}cific. MtDNA divers.ty was.low in 9 p.p.lations.but micros.tellite divers.ty was.moderate to high in all p.p.lations. Micros.tellite data s.gges. 10 genetic clus.ers.and low level of gene flow throughout the s.udied area. However, p.ys.cal barri- ers. s.ch as.rivers.and mountain ranges. or the p.es.nce or abs.nce of fores. ap.ear to be unrelated to p.p.lation clus.ers. Factors.s.ch as.low dis.0}rs.l, different ecological con- ditions. and is.lation by dis.ance are mos. likely s.ap.ng the p.p.lation s.ructure of this.s.0}cies. Thus.far, nes. trans.0}rtation has.not influenced the general p.p.lation s.ructure in the s.udied area. However, due to the genetic s.ructure we found, we recommend that nes. trans.0}rtation s.ould only occur within and between p.p.lations.that are genetically s.milar.

The new ternary YbZn0.7Inl.3 comp.und was.s.nthes.zed in evacuated quartz amp.ules.at 900 ℃, followed by annealing at 400 ℃. It crys.allized in the UHg2 s.ructure typ. with a=0.47934（5） nm, c=0.36955（5） nm, V=0.073535（15） nm3. The s.ortes. dis.ances.between the atoms.in this.s.ructure were equal to 0.3696 nm （Yb-Yb）, 0.3328 nm （Yb-M） and 0.2767 nm （M M）, res.0}ctively. Magnetization meas.rements.indicated that the title comp.und exhibited a p.ramagnetic behavior down to 2 K, with antiferromagnetic-like interactions. Calculated magnetic moment for YbZn0.7inl.3 （μeft =3.86μB/Yb） could indicate mixed valence s.ate of Yb.
