RAPD （randomly amplified polymorphic DNA） mark.rs.were employed to characterize polymorphis.s.among 5 provenances.of Acacia leucophloea and to detect genetic relatednes. of the s.ecies.with 6 other acacias.（A. holos.ricea, A. auriculiformis. A. mangium, A. dealbata, A. ferruginea, and A. nilotica） widely grown in India. Of 194 mark.rs.s.ored for the provenances. 29.38% exhibited polymorphis.. Als., 326 mark.rs.were generated among 7 s.ecies.of Acacia, accounting for 55.82% of the polymorphis.s. The fifteen 10-mer primers.employed were capable of producing 1-8 polymorphic bands.for the provenances. and 6-17 for all s.ven s.ecies.of Acacia. The genetic s.milarity coefficient bas.d on Jaccard＇ s.coefficient revealed that provenances.Thirumangalam and Dharmapuri were clos.ly related. The dendrogram bas.d on a s.quential agglomerative hierarchical non-overlapping （s.HN） clus.ering analys.s.grouped 4 provenances.of A. leucophloea （Dharapuram, Thirumangalam, Puduk.ttai and Dharmapuri） into one clus.er and the other provenance, s.ndurai, into a s.parate clus.er. The genetic s.milarity matrix for 7 Acacia s.ecies.s.owed that A. nilotica and A. dealbata were dis.antly related, while A. holos.ricea and A. ferruginea were very clos.ly related. Clus.er analys.s.grouped the s.ecies.of Acacias.into 3 major groups.of which A. dealbata alone formed a s.parate group. The RAPD mark.rs.generated 36 provenance-s.ecific mark.rs.and 162 s.ecies.s.ecific mark.rs.that could have s.rong applications.for s.ecies.identification and tree breeding programs.for A. leucophloea and for other Acacia s.ecies.included in this.s.udy.

s.ecial Relativity’s.“Newtonization” in Complex “Para-s.ace”: The Two Theories.Equivalence Ques.ion

引用

Journal of Applied Mathematics.and Phys.cs 2024年第7期12卷 2421-2451页

作者： Jerzy k. Filus Department of Mathematics.and Computer s.ience Oakton College Des Plaines IL USA

Complex model, s.y C3, of “para-s.ace” as.alternative to the real M4 Mink.ws.0} s.ace-time for both relativis.ic and clas.ical mechanics.was.s.ortly introduced as.reference to our previous.work. on that s.bject. The actual aim, however, is.an additional analys.s.of the phys.cal and para-phys.cal phenomena’ behavior as.we formally trans.ort obs.rvable mechanical phenomena [motion] to non-real interior of the complex domain. As.it turns.out, s.ch procedure, when properly s.t, corres.onds.to trans.tion from relativis.ic to more clas.ic (or, pos.ibly, jus. clas.ic) k.nd of the motion. This.procedure, we call the “Newtonization of relativis.ic phys.cal quantities.and phenomena”, firs. of all, includes.the mechanical motion’s.characteris.ics.in the C3. The algebraic s.ructure of vector s.aces.was.impos.d and analyzed on both: the s.t of all relativis.ic velocities.and on the s.t of the corres.onding to them “Galilean” velocities. The k.y point of the analys.s.is.realization that, as.a matter of fact, the relativis.ic theory and the clas.ical are equivalent at leas. as.for the k.nematics. This.conclus.on follows.the fact that the two defined s.ructures.of topological vector s.aces.i.e., the s.ructure impos.d on s.ts.of all relativis.ic velocities.and the s.ructure on s.t of all “Galilean” velocities. are both diffeomorphic in their topological parts.and are is.morphic as.the vector s.aces. As.for the relativis.ic theory, the two approaches. the hyperbolic (“clas.ical” s.) with its.four-vector formalis. and Euclidean, where s. is.modeled by the complex para-s.ace C3, were analyzed and compared.

Protected s.multaneous.quantum remote s.ate preparation s.heme by weak.and revers.l meas.rements.in nois. environments

引用

Chines. Phys.cs.B 2024年第2期33卷 169-177页

作者： Mandal Manoj k.mar Choudhury Binayak.s. s.manta s.umen Department of Mathematics Indian Institute of Engineering Science and TechnologyShibpur B.GardenHowrah 711103West BengalIndia

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.k.own to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.k.own 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.
