We investigate the quantum Fisher information(QFI) of a qubit-qutrit system in the background of Garfinkle–Horowitz–Strominger dilation black hole. After deriving the analytical expression of the QFI, we examine its dynamics with respect to the dilation parameter D and the state parameter γ of the system. Our results show that the QFI for the estimation of γ is a fixed value,which is independent of the parameters D and γ. And the QFI for the estimation of D varies with the parameters D and γ. Additionally, we propose an effective strategy to steer the QFI by introducing weak measurement reversal. We find that the QFI can be remarkably enhanced by adjusting the appropriate reversing measurement strengths. Our findings might provide some useful insights for the study on parameter estimation of hybrid systems in the framework of relativity theory.

Quantum teleportation(QT) [1] enables secure transfer of an unknown quantum state between remote locations without physically transmitting the initial state. Unlike QT,with the sender possessing complete knowledge of the initial state, remote state preparation(RSP) [2] exhibits a tradeoff between the amount of the entanglement resource used and the classical communication cost.

Solvent effects on 2,4-dinitrotoluene（2,4-DNT） molecule in different solvents（toluene, ethanol, and water） were studied via DFT PCM method at B3LYP/6-311＋G（d,p） level. The influences of these solvents on the molecular structure, vibrational spectra, charge distribution, and dipole moment were studied as well. The results show that PCM computations are successful in describing the vibrational spectra of 2,4-DNT molecules in these solutions and the solvent effects on the low frequency vibrational spectra are weak.

The development of optical films with high transparency,high thermal resistance and low birefringence remains a challenge in the flexible display *** this work,we designed and synthesized a series of fluorinated colorless polyimides(CPIs)materials using 2,5-substituted m-phenylenediamine diamine monomers and 1,2,4,5-cyclohexanetetracarboxylic dianhydride(CHDA).We systematically studied the effects of fluorinated group substitutions on the thermal,mechanical,optical and dielectric properties of CPI *** introduction of alicyclic CHDA dianhydride affords high transparency and low yellowness,while the 2,5-substituted m-phenylenediamine diamines offer the CPIs with quite low birefringence as well as high glass transition temperatures.A particular CHDA/o3FBDA film with simple chemical structure stands out,exhibiting well-balanced overall properties.

AIM： To investigate whether extracellular signal-regulated kinase 1 （ERK1） is activated and associated with hepatic stellate cell （HSC） proliferation in fibrotic rat liver tissue.METHODS： Rat hepatic fibrosis was induced by bile duct ligation （BDL）. Histopathological changes were evalo uated by hernatoxylin and eosin staining, and Masson＇ s trichrorne method. ERK1 mRNA in rat liver tissue was determined by reverse transcription-polyrnerase chain reaction, while the distribution of ERK1 was assessed by irnrnunohistochernistry. ERK1 protein was detected by Western blotting analysis. The number of activated HSCs was quantified after alpha smooth muscle actin （α-MA） staining.RESULTS： With the development of hepatic fibrosis, the positive staining cells of α-SMA increased obviously, and mainly resided in the portal ducts. Fiber sepia and perisinuses were accompanied with proliferating bile ducts. The positive staining areas of the rat livers in model groups 1-4 wk after ligation of common bile duct （12.88% ± 2.63%, 22.65% ± 2.16%, 27.45% ± 1.86%, 35.25% ± 2.34%, respectively） were significantly larger than those in the control group （5.88% ± 1.46%, P 〈 0.01）. With the development of hepatic fibrosis, the positive cells of ERK1 increased a lot, and were mainly distributed in portal ducts, fiber sepia around the bile ducts, vascular endothelial cells and perisinusoidal cells. Western blotting analysis displayed that the expression of ERK1 and ERK1 protein was up-regulated during the model course, and its level was the highest 4 wk after operation, being 3.9-fold and 7.2-fold higher in fibrotic rat liver than in controls. ERK1 mRNA was expressed in normal rat livers as well, which was up-regulated two days after BDL and reached the highest 4 wk after BDL. The expression of ERK1 was positively correlated with α-MA expression （r = 0.958, P 〈 0.05）.CONCLUSION： The expression of ERK1 protein and mRNA is greatly increased in fibrotic rat liver tissues, which may play a key r

The mean depth of the extensioncatheter intubation was 20.56 ± 13.05 mm, and the mean rapid exchange catheterservice time was 18.9 ± 9.7 min. The mean length and diameter of stents were 33.5± 14.4 mm and 2.75 ± 0.45 mm, respectively.
