Finding available subclasses in high-dimensional medical databases using cluster.ng techniques is consider.d as ver. impor.ant one in medical field. Due to similar.intensi- ties between the datapoints in high-dimensionality cancer.medical database cluster.ng techniques have failed to cluster.the available subclasses with less er.or. Ther.for. this paper.pr.sents suitable fuzzy-based cluster.ng techniques to find available subclasses in high-dimensional pr.state and br.ast cancer.databases. In addition this paper.pr.sents pr.totype initialization algor.thm to avoid r.ndom initialization of initial pr.totypes. In or.er.to evaluate the per.or.ance of pr.posed cluster.ng techniques exper.mental study has been per.or.ed on benchmar. databases. Finally the pr.posed methods have been successfully implemented to find the subclasses of cancer. in pr.state and br.ast cancer.databases. The cluster.ng r.sults of pr.posed methods have been validated by evaluating cluster.ng accur.cy.

Pur. and Smdoped NdOnanophosphor. wer. synthesized using modified Pechini method. The phase for.ation with symmetr. of the sample is confir.ed by the r.etveld r.finement of the powder.Xr.y diffr.ction(PXr.) data. The sur.ace mor.hology and the cr.stallite size wer. examined using scanning electr.n micr.scopy(SEM) and tr.nsmission electr.n micr.scopy(TEM) and the r.sults confir.ed that the synthesized par.icles ar. in nanosize. The ener.y-disper.ive X-r.y(EDX) analysis was done to confir. the pur.ty of the sample. The optical pr.per.ies of the sample wer. studied using ultr.violet-visible r.nge(UV-Vis) spectr.scopic analysis and photoluminescence studies. The calculated band gap of the synthesized NdOwas found to be higher.than that of bulk NdO. The photoluminescence(PL) of the pr.par.d samples r.veals that doping with Sm3+ ion has influenced the optical pr.per.ies. Quantitative investigation on char.e density distr.bution was done by analysing the 3-dimensional and 2-dimensional char.e density maps dr.wn along the bonding dir.ctions. The maximum entr.py method(MEM)/r.etveld analysis was used for.the fir.t time to analyse the char.e density in the chosen system. Char.e density ar.angement in the unit cell is cor.elated to the analysed photoluminescent(PL) pr.per.ies. The spectr.l behaviour.of the samples has been explained thr.ugh char.e or.er.ng which ar. ver.fied using exper.mental data obtained. The studies on these mater.als have shown that these nanophosphor. will pr.vide pr.mising application for.near.ultr.violet lightemitting diodes(n-UV-LEDs).

It is known that the dynamical evolution of a system, fr.m an initial tensor.pr.duct state of system and envir.nment, to any two later.times, t1, t2 (t2 > t1), ar. both completely positive (CP) but in the inter.ediate times between t1 and t2 it need not be CP. This r.veals the key to the Mar.ov (if CP) and non Mar.ov (if it is not CP) avatar.s of the inter.ediate dynamics. This is br.ught out her. in ter.s of the quantum stochastic map A and the associated dynamical map B—without r.sor.ing to master.equation appr.aches. We investigate these featur.s with four.examples which have entir.ly differ.nt physical or.gins: 1) A two qubit Wer.er.state map with time dependent noise par.meter.2) Phenomenological model of a r.cent optical exper.ment (Natur. Physics, 7, 931 (2011)) on the open system evolution of photon polar.zation;3) Hamiltonian dynamics of a qubit coupled to a bath of N qubits;4) Two qubit unitar. dynamics of Jor.an et al. (Phys. r.v. A 70, 052110 (2004) with initial pr.duct states of qubits. In all these models, it is shown that the positivity/negativity of the eigenvalues of inter.ediate time dynamical B map deter.ines the Mar.ov/non-Mar.ov natur. of the dynamics.
