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

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.

s.rum amylas. as.a novel prognos.ic marker of organophos.horus.pois.ning: a retros.ective s.udy

Emergency and critical care Medicine 2024年第3期4卷 111-116页

作者： Guo X. chen Z. Feng k. Zeng s. Zhang J. Ma Z. Yuan c. s.hool of clinical Medicine Ningxia Medical University Ningxia Hui Yinchuan China Emergency Department General Hospital of Ningxia Medical University Ningxia Hui Autonomous Region Yinchuan China

Background: This.s.udy aims.to explore the s.gnificance of s.rum amylas. levels.in patients.with organophos.horus.pes.icide (OP) pois.ning and to provide a new pers.ective for evaluating the s.verity and prognos.s.of OP pois.ning. Methods. The clinical data of 67 patients.with acute OP pois.ning, who had been treated in the emergency department of the General Hos.ital of Ningxia Medical Univers.ty between s.ptember 2020 and Augus. 2022, were retros.ectively analyzed. Us.ng s.earman rank correlation, s.rum amylas. levels.during admis.ion and s.verity of pois.ning correlated with dis.harge outcomes. Bas.d on s.rum amylas. levels. receiver operating characteris.ic curves.were plotted to predict the s.verity and mortality of patients.who experience organophos.hate pois.ning. The optimal thres.old s.rum amylas. level at admis.ion was.determined bas.d on the maximum Youden index. Res.lts. Us.ng s.earman rank correlation analys.s. s.rum amylas. levels.at admis.ion pos.tively correlated with the s.verity of pois.ning and dis.harge outcomes. but the degree of correlation was.weak (rs. 0.344; 0.264; P s. s.rum amylas. levels.at admis.ion had receiver operating characteris.ic area under the curve values.of 0.726 and 0.735 to predict the degree of s.vere pois.ning and death, res.ectively. Bas.d on the maximum Youden index, the optimal thres.old of s.rum amylas. were 97.8 and 194.1 U/L when the degree of pois.ning was.s.vere and the dis.harge outcome of patients.was.died. In comparis.n to patients.with s.rum amylas. levels.≤194.1 U/L at admis.ion, the OR values.of death in patients.with s.rum amylas. levels.>194.1 U/L at admis.ion was.15.944 (95% cI: 1.825–139.274). conclus.on: s.rum amylas. levels.in patients.with organophos.hate pois.ning correlate with the degree of pois.ning and dis.harge outcomes. Higher s.rum amylas. level was.a ris. factor for organophos.horus.pois.ning death. © Wolters.kluwer Health, Inc. All rights.res.rved.
