High-temperature X-ray diffraction (HTXRD) measurements of LaCoO_3 powder was carried out in a temperature range from 298 to 1273 K. The experimental data obtained were adopted to evaluate the lattice parameters and cell volume. In this temperature range, the linear and volume expansion coefficients calculated using these cell parameters are 24.160～23.610×10^(-6)·K^(-1) and 59.601～63.218×10^(-6)·K^(-1) respectively. There is no discontinuity found in the cell parameters through the proposed first-order transition at 1210 K.

Background: Evidence shows an association between grip strength and health;however, grip strength cut-offs for the detection of metabolic syndrome(MetS) in Latin American populations are scarce. The purpose of this study was to determine cut-offs of normalized grip strength(NGS)for the detection of MetS in a large nonrepresentative sample of a collegiate student population from ***: A total of 1795 volunteers(61.4% female;age = 20.68 ± 3.10 years, mean ± SD), ranging between 18 and 30 years of age participated in the study. Strength was estimated using a handheld dynamometer and normalized to body mass(handgrip strength(kg)/body mass(kg)). Anthropometrics, serum lipids indices, blood pressure, and fasting plasma glucose were measured. Body composition was measured by bioelectrical impedance analysis. MetS was defined as including ≥3 of the 5 metabolic abnormalities according to the International Diabetes Federation definition. A metabolic risk score was computed from the following components: waist circumference, triglycerides, high-density lipoprotein cholesterol, glucose, and systolic and diastolic blood ***: Receiver operating curve analysis showed significant discriminatory accuracy of NGS in identifying the thresholds and risk *** strength was associated with increased prevalence of MetS. In males, weak, intermediate, and strong NGS values at these points were0.615, respectively. In females, these cut-off points were 0.437, ***: Our sex-specific cut-offs of NGS could be incorporated into a clinical setting for identifying college students at cardiometabolic disease risk.

Recently,the experimental measurements of the branching ratios and different polarization asymmetries for processes occurring through flavor-changing-charged current（b→cτvτ）transitions by BABAR,Belle,and LHCb have revealed some significant differences from the corresponding Standard Model（SM） *** has triggered an interest to search for physics beyond the SM in the context of various new physics（NP） models and using the model-independent weak effective Hamiltonian（WEH）.Assuming left-handed neutrinos,we add the dimension-six vector,（pseudo-）scalar,and tensor operators with complex Wilson coefficients（WCs） to the SM *** 60%,3 0%,and 10% constraints resulting from the branching ratio of Bc→τvτ,we reassess the parametric space of these new physics WCs accommodating the current anomalies based on the most recent HFLAV data of Rτ/μ,e（D） and Rτ/μ,e（D*） and Belle data of FL（D*） and Pτ（D*）.We find that the allowed parametric region of lefthanded scalar couplings strongly depends on the constraints of the Bc→τvτbranching ratio,and the maximum pull from the SM predictions results from the measurements of Rτ/μ（J/ψ） and Rτ/l（Xc）,we derive the sum rules which complement them with Rτ/μ,e（D） and Rτ/μ,e（D*）.Using the best-fit points of the new complex WCs along with the latest measurements of Rτ/μ,e(D（*）),we predict the numerical values of the observable Rτ/l（Λc）,Rτ/μ（J/ψ）,and Rτ/l（Xc） from the sum *** simultaneous dependence of abovementioned physical observables on the NP WCs is established by plotting their correlation with RDand RD*,which are useful to discriminate between various NP *** find that the most significant impact of NP results from the WC CLS=***,we study the impact of these NP couplings on various angular and CP triple product asym

In order to increase the available power of the electrical energy distribution station and improve the voltage profile of the distribution lines, the use of shunt capacitor banks is indicated. The main results obtained during this study are: a reduction in subscribed power from 14913.978 kVA to 14010.100 kVA, a reduction in the transformer load rate from 99.4% to 93.4%, a reduction in reactive power called from 5481.729 kVAr to 481.729 kVAr, an increase in the active power transported by the substation from 8505.062 kW to 8962.323 kW, a reduction in the voltage drop from 4.8% to 3.9%, an increase in the power available at the secondary of the transformer station at full load from 13950 kW to 14700 kW and an annual electrical energy saving of 339943.48 kWh of electrical energy, therefore fuel savings and a reduction in CO2 and SO2 emissions due to this energy saving will be achieved. The installation of capacitor banks for optimization of reactive energy allowed a reduction in the current called therefore a reduction in the absorbed power: 14153.061 kVA, i.e. a reduction of 903.876 kVA. It is therefore essential that energy players are convinced of the need to install capacitors to reduce or even eliminate their reactive energy bill. This is necessarily accompanied by an investment by Electricité De Guinée by setting up active and reactive energy meters but also by implementing pricing in line with the reduction in the transfer of reactive energy in the network.

Faithful long-distance quantum teleportation necessitates prior entanglement distribution between two communicated locations. The particle carrying on the unknown quantum information is then combined with one particle of the entangled states for Bell-state measurements, which leads to a transfer of the original quantum information onto the other particle of the entangled states. However in most of the implemented teleportation experiments nowadays, the Bell-state measurements are performed even before successful distribution of entanglement. This leads to an instant collapse of the quantum state for the transmitted particle, which is actually a single-particle transmission thereafter. Thus the true distance for quantum teleportation is, in fact, only in a level of meters. In the present experiment we design a novel scheme which has overcome this limit by utilizing fiber as quantum memory. A complete quantum teleportation is achieved upon successful entanglement distribution over 967 meters in public free space. Active feed-forward control techniques are developed for real-time transfer of quantum information. The overall experimental fidelities for teleported states are better than 89.6%, which signify high-quality teleportation.
