High res.lution las.r induced fluores.ence, s.ectra of IrN in the s.ectral region between 394 and 520 nm were recorded us.ng las.r vaporization/reaction free jet expans.on and las.r induced fluores.ence s.ectros.opy. s.ven new vibronic trans.tion bands.were obs.rved and analyzed. Two Ω=1 and five Ω=0 new s.ates.were identified. Leas. s.uares.fit of rotationally res.lved trans.tion lines.yielded accurate molecular cons.ants.for the upper s.ates. s.ectra of is.topic molecules.were obs.rved, which provided confirmation for the vibrational as.ignment. Comparis.n of the obs.rved electronic s.ates.of IrB, IrC, and IrN provides.a good unders.anding of the chemical bonding of this.group of molecules.

We des.ribe briefly here the recent R&D activities.in the optical s.bas.embly packaging technologies.at the Hong Kong Applied s.ience and Technology Res.arch Ins.itute (As.RI). We have des.gned, developed and prototyped multiple of low-cos. high performance packages.for s.rial and parallel trans.itters.and receivers. in particular, the novel chip-in-plas.ic (CiP) package des.gned for 10G s.rial trans.is.ion for data communications.

The increas.ng s.ocks.of public infras.ructure and s.rious.deterioration of infras.ructure s.s.ems.due to corros.on pres.nt great financial, s.fety, technical and operational challenges.to government organizations.in charge of public infras.ructure development and management. To meet thos. challenges. a performance-bas.d life-cycle management model for reinforced concrete s.ructures.was.propos.d in this.paper. This.model predicts.the life-cycle performance of infras.ructure bas.d on the corros.on-induced deterioration mechanis.： condition index as.well as.performance limit s.ates. A cas. s.udy is.provided to demons.rate the us. of the propos.d performance-bas.d life-cycle cos. management model.

Primary malignancies.of the s.all bowel are rare and us.ally pres.nt with vague, non-s.ecific s.mptoms. This.leads.to diagnos.ic difficulties.for both phys.cian and radiologis.s.alike. We pres.nt a cas. of a 54-year-old lady with a virgin abdomen who initially pres.nted to hos.ital with vague abdominal s.mptoms.s.gges.ive of gas.roenteritis. s.e res.onded partially to cons.rvative treatment but repres.nted to hos.ital 3 weeks.later with obs.ructive s.mptoms. Contras. CT was.inconclus.ve with regards.to diagnos.s. A diagnos.ic laparos.opy was.performed, revealing an infiltrative growth. Cons.quently, s.e underwent s.gmental laparos.opic-as.is.ed s.all bowel res.ction and recovered well pos.-operatively. After further his.ological and endos.opic inves.igations. a final diagnos.s.of primary s.all bowel adenocarcinoma was.given. As.the prognos.s.of s.all bowel malignancy is.s.age-dependent, this.cas. demons.rates.a high index of s.s.icion is.neces.ary to reach early diagnos.s. es.ecially for s.mptoms.non-res.ons.ve to conventional treatment. Diagnos.ic laparos.opy s.ould be cons.dered early as.a definitive diagnos.ic tool.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.
