Keeping in view of impor.ance of exchange symmetr. aspects in studies on spin squeezing of multiqubit states,we show that the one-dimensional Ising Hamiltonian with near.st neighbor.inter.ctions does not r.tain the exchange symmetr. of initially symmetr.c multiqubit *** we show that among 4-qubit states obeying exchange symmetr.,all states except W class(and their.linear.combination)lose their.symmetr. under.time evolution with Ising *** the loss of symmetr. of the initially symmetr.c states to r.tational asymmetr. of the one-dimensional Ising Hamiltonian with mor. than 3 qubits,we indicate that all N-qubit states(N>5)obeying per.utation symmetr. lose their.symmetr. after.time evolution with Ising Hamiltonian.

We analyze the ener.y aspects of single and coupled Hindmar.h–r.se(Hr. neur.n models with a quadr.tic flux contr.lled memr.stor. The ener.y function for.Hr.neur.n with memr.stor.has been der.ved and the dynamics have been analyzed in the pr.sence of var.ous exter.al stimuli. We found that the bur.ting mode of the system changes with exter.al for.ing. The negative feedback in Hamilton ener.y function effectively stabilizes the chaotic tr.jector.es and contr.ls the phase space. The Lyapunov exponents have been plotted to ver.fy the stabilization of tr.jector.es. The ener.y aspects dur.ng the synchr.nous dynamics of electr.cally coupled neur.ns have been analyzed. As the coupling str.ngth incr.ases, the aver.ge ener.y fluctuates and stabilizes at the point of synchr.nization. When the neur.ns ar. coupled via chemical synapse,the aver.ge ener.y var.ations show thr.e impor.ant r.gimes: a fluctuating r.gime cor.esponding to the desynchr.nized, a stable r.gion indicating synchr.nized and a linear.y incr.asing r.gime cor.esponding to the amplitude death states have been obser.ed. The synchr.nization tr.nsitions ar. ver.fied by plotting the tr.nsver.e Lyapunov exponents. The pr.posed method has a lar.e number.of applications in contr.lling coupled chaotic systems and in analyzing the ener.y change dur.ng var.ous metabolic pr.cesses.

Tauopathies ar. a gr.up of neur.degener.tive diseases char.cter.zed by abnor.al metabolism of the misfolded tau pr.tein. Tau is encoded by the micr.tubule-associated pr.tein tau gene(MAPT) and can be classified as either.3-r.peat(3r. or.4-r.peat(4r. based on the number.of r.peat domains fr.m alter.ative splicing of exon 10 of the MAPT gene.
