[en] The soft gluon resummation effect in the Higgs boson plus two-jet production at the LHC is studied by applying the transverse momentum dependent factorization formalism. The large logarithms, introduced by the small total transverse momentum of the Higgs boson plus two-jet final state system, are resummed to all orders in the expansion of the strong interaction coupling with the accuracy of Next-to-Leading Logarithm order. This significantly improves the theoretical prediction. We also compare our result with the prediction of the Monte Carlo event generator Pythia8, and find noticeable difference in the distributions of the total transverse momentum and the azimuthal angle correlations of the final state Higgs boson and two-jet system, when applying similar kinematic cuts used in the LHC data analysis. This difference is large enough to affect the measurement of Higgs boson coupling to the vector boson at the future High luminosity LHC.

[en] Scanning electrochemical microscopy (SECM) is employed to investigate the effect of solution viscosity on the rate constants of electron transfer (ET) reaction between potassium ferricyanide in water and 7,7,8,8-tetracyanoquinodimethane (TCNQ) in 1,2-dichloroethane. Either tetrabutylammonium (TBA⁺) or ClO₄^- is chosen as the common ion in both phases to control the interfacial potential drop. The rate constant of heterogeneous ET reaction between TCNQ and ferrocyanide produced in-situ, k₁₂, is evaluated by SECM and is inversely proportional to the viscosity of the aqueous solution and directly proportional to the diffusion coefficient of K₄Fe(CN)₆ in water when the concentration of TCNQ in the DCE phase is in excess. The k₁₂ dependence on viscosity is explained in terms of the longitudinal relaxation time of the solution. The rate constant of the heterogeneous ET reaction between TCNQ^- and ferricyanide, k₂₁, is also obtained by SECM and these results cannot be explained by the same manner

[en] A method for the determination of gadolinium isotope abundance ratio of irradiated gadolinium by thermal ionization mass spectrometry (TIMS) has been established. The natural gadolinium oxide was prepared into a target and placed in the preset channel of high flux engineering test reactor (HFETR) to receive neutron irradiation. The total irradiation time was 91.3 h, the reactor power was 80 MW, and the neutron flux rate of irradiated channel was about 2 × 10¹⁴ n · cm^-2 · s^-1. After irradiation, the radiation and measurement of gadolinium (Gd) of flammable neutron poisons were completed by cutting, transporting, dissolving, sampling and measuring the targets, then the measured values were corrected. The results showed that the analyzing date for the post-irradiation testing of Gd by TIMS was accurate and reliable. The post treatment method of the sample after irradiation was reasonable. The variation of the isotopic abundance of various gadolinium was consistent and closely related to the neutron absorption cross section. This method can be used for isotopic analysis of gadolinium in uranium/gadolinium mixed fuel pellets and unloading element. After the measured data are obtained, it can be used to revise the theoretical calculation in order to obtain better reactor core design scheme. (authors)

[en] In this paper the authors investigate a class of $p$-Laplace equations with logarithmic nonlinearity, which were considered in Le and Le (Acta Appl. Math. 151:149–169, 2017), where, among other things, global existence and finite time blow-up of solutions were proved when the initial energy is subcritical and critical, that is, initial energy smaller than or equal to the depth of the potential well. Their results are complemented in this paper in the sense that an abstract criterion is given for the existence of global solutions that vanish at infinity or solutions that blow up in finite time, when the initial energy is supercritical. As a byproduct it is shown that the problem admits a finite time blow-up solution for arbitrarily high initial energy.

[en] Using the AdS/CFT correspondence, we study the hydrodynamics with conserved current from the dual Maxwell-Gauss-Bonnet gravity. After constructing the perturbative solution to the first order based on the boosted black brane solution in the bulk Maxwell-Gauss-Bonnet gravity, we extract the stress tensor and conserved current of the dual conformal fluid on its boundary, and also find the effect of the Gauss-Bonnet term on the dual conformal fluid. Our results show that the Gauss-Bonnet term can affect the parameters such as the shear viscosity η, entropy density s, thermal conductivity κ and electrical conductivity σ. However, it does not affect the so-called Wiedemann-Franz law which relates κ to σ, while it affects the ratio η/s. In addition, another interesting result is that η/s can also be affected by the bulk Maxwell field in our case, which is consistent with some previous results predicted through the Kubo formula. Moreover, the anomalous magnetic and vortical effects by adding the Chern-Simons term are also considered in our case in the Maxwell-Gauss-Bonnet gravity.

[en] Objective: To evaluate the effects of percutaneous transhepatic variceal obliteration in the treatment of acute bleeding from gastroesophageal varices in patients with severe cirrhosis. Methods: 19 patients with Child C cirrhosis suffered from active bleeding from gastroesophageal varices. Emergency procedures of percutaneous transhepatic variceal obliteration were performed in all 19 patients. Results: Successful catheterization and obliteration of the varices in all of the 19 cases. Active bleeding were controlled in 18 cases with only one failure and TIPSS was performed. During a follow-up period ranging from one to 12 months, 14 cases bled recurrently during 3 to 12 months. 15 cases died within the follow-up period. 4 cases were alive. Severe complication of intraperitoneal bleeding occurred in 1 case, and laparotomy was performed. Conclusions: Percutaneous transhepatic variceal obliteration is effective in controlling acute bleeding from gastroesophageal varices in patients with Chile C cirrhosis. It could be used as the first choice treatment method for emergency when TIPSS is contraindicated

Conclusions: Endovascular stenting is a safe and valid method of choice for the treatment of complicated extracranial carotid stenosis in high surgical risk patients. (authors)

[en] Differential diagnosis between central neurocytoma and ependymoma is very important for making preoperative scheme. We explored the application of diffusion-weighted imaging (DWI) combined with apparent diffusion coefficient (ADC) in differential diagnosis between both. The data of preoperative MR plain and contrast-enhanced scan, DWI and ADC values of neoplastic solid parts from 18 cases with central neurocytoma and 19 cases with lateral ventricular ependymoma, were retrospectively analyzed. Mann-Whitney test was used for the comparison of ADC values between central neurocytoma and ependymoma. The application of ADC values in the differential diagnosis between central neurocytoma and ependymoma was evaluated by ROC curve. The lesions showed hyperintensity-dominant mixed signal intensity on DWI and mean ADC was (0.65 ± 0.13) × 10${}^{-<!--\; ???\; -->3}$ mm${}^2$/s in the 18 cases with central neurocytoma. In the 19 cases with ependymoma, 13 had hyperintensity-dominant mixed signal intensity on DWI and 6 had hypointensity-dominant mixed signal intensity on DWI, and mean ADC was (1.20 ± 0.23) × 10${}^{-<!--\; ???\; -->3}$ mm${}^2$/s. The mean ADC value was significantly higher in the 19 cases with ependymoma than in the 18 cases with central neurocytoma (P < 0.001). The ADC of 0.87 × 10${}^{-<!--\; ???\; -->3}$ mm${}^2$/s might be used as a threshold for differential diagnosis between central neurocytoma and ependymoma with an area under ROC curve of 0.98 ± 0.02 and a 95% confidence interval of 0.95–1.00. Its sensitivity, specificity, and accuracy were 90%, 100%, and 90%, respectively. There is a certain overlap in MRI imaging features between central neurocytoma and ependymoma. DWI combined with ADC value can improve peoperative diagnostic accuracy.

[en] Electric charge neutrality provides a relationship between chiral dynamics and neutrino propagation in compact stars. Due to the sudden drop of the electron density at thefirst-order chiral phase transition, the oscillation for low energy neutrinos is significant and can be regarded as a signature of chiral symmetry restoration in the core of compact stars.

[en] Objective: To investigate the effect of ¹³¹I combined with artificial liver plasma exchange therapy on patients with Graves hyperthyroidism combined with liver damage, and to provide guidance for future clinical practice. Methods: A retrospective analysis of 156 cases from 2004 to 2014 treated with ¹³¹I combined with artificial liver plasma exchange therapy was conducted. According to the reasons of liver damage, these patients were divided to the hyperthyroidism liver injury (A group), antithyroid drug-induced liver injury (B group), and liver damage caused by other diseases (C group) groups. According to the degrees of liver damage, each group was divided into the moderate and severe liver damage subgroups. Among three groups, we collected and compared general information, medical history, data on treatment, liver function and thyroid function before and after the treatment, as well as the changes outcomes. The statistical data analysis was conducted with SPSS 17.0 software. Results: (1) Three groups included 93 cases, 25 cases, and 38 cases, respectively. There were no significant differences in general data across groups (P > 0.1); (2) Before the treatment (TO) and after 6 months of the treatment (T6) the indexes (FT3, FT4, ALT, AST, ALP, GGT, TBIL) were significant difference across groups (P < 0.01); (3) Six months after the treatment, the efficiencies were 100%, 92.0%, and 89.2%, respectively. Conclusion: The treatment of Graves hyperthyroidism combined with moderate to severe liver damage using ¹³¹I combined with artificial liver plasma exchange is effective, and the timing of treatment should be accurately determined.
