The lithium ionic conductingLa0.45Ce0.1Li0.27TiO3 has been synthesized by sol-gel method. This solid is the result of substitutional doping with Ce(IV) in La0.45Ce0.1Li0.27TiO3 compound. The aim of the replacement of La(III) by Ce(IV) is increase the number of vacancies in the structure and favors the ionic mobility. Structural characterization shows that the obtained material have the expected tetragonal P4/mmm perovskite structure. Chemical analysis shows that composition was homogeneus in all the sample. The bulk conductivity measured at room temperature is about the same as previously reported for its related lanthanum lithium titanate. However, the lower activation energy for ionic conduction encourages further searching for better conductors in this system.

The growing demand for air travel has led to the saturation of air traffic *** methods of adding routes to alleviate congestion and reduce delays may not achieve the desired effect and even degrade system *** this paper,we explore the application of Braess’s Paradox in the reduction of air traffic *** counterintuitive phenomenon shows that adding new connections to a network can actually increase the overall network *** study uses Hidden Markov methods and the Viterbi algorithm to match air traffic flow with routes,a machine learning approach and a mathematical method to construct cost functions for flight time and traffic volume,and finally uses genetic algorithm and the A*algorithm to detect Braess’s Paradox *** uses ADS-B data from the busy month of July 2019 for a case study of the air traffic network over the UK *** results show that Braess’s Paradox is also applicable to multi-flight level air route *** such network edges can improve system *** one day’s case,the total flight time of the day’s traffic volume decreased from 11509.24 minutes to 10459.97 *** equates to an average savings of 4.99 minutes of flight time per flight,which is significant in controlling delay performance.

An experience is presented using the finite element method （FEM） and data mining （DM） techniques to develop models that can be used to optimieze the skin-pass rolling process based on its operating conditions. A FE model based on a real skin-pass process is built and validated. Based on this model, a group of FE models is simulated with different adjustment parameters and with different materials for the sheet; both variables are chosen from pre-set ranges, From all FE model simulations, a database is generated; this database is made up of the above mentioned adjustment parameters, sheet properties and the variables of the process arising from the simulation of the model. Various types of data mining algorithms are used to develop predictive models for each of the variables of the *** best predictive models can be used to predict experimentally hard-to-measure variables （internal stresses, internal straine, etc.） which are useful in the optimal design of the process or to be applied in real time control systems of a skin-pass process in -plant.

Tracking persons in dangerous situations as well as monitoring their physical condition, is often crucial for their safety. The systems commonly used for this purpose do not include individual monitoring or are too expensive and intrusive to be deployed in common situations. In this project, a mobile system based on energy-efficient wireless sensor networks (WSns) and active radio frequency identification (RFID) has been developed to achieve ubiquitous positioning and monitoring of people in hazardous situations. The system designed can identify each individual, locate him/her, send data regarding their physical situation, and ascertain whether they are located in a confined space. A new algorithm called time division double beacon scheduling (TDDBS) has been implemented to increase operation time and data transmission rate of the nodes in the system. The results show that the use of this system allows us to find the location and state of a person, as well as to provide an analysis of the potential risks at each moment, in real time and in an energy-efficient way. In an emergency, the system also allows for quicker intervention, as it not only provides the location and causes of the event, but also informs about the physical condition of the individual at that moment.

The dilepton invariant mass spectra and integrated branching ratios of the single and double Dalitz decays P→l^＋l^-γ and P→l^＋l^-l^＋l^-（P=π^0,η,η＇;l=e or μ） are predicted by means of a data-driven approach based on the use of rational approximants applied to π^0,η and η＇ transition form factor experimental data in the space-like region.

AIM： To assess whether CCL2 or interactions between this chemokine and its receptor （CCR2） are associated with outcomes of chronic hepatitis C and with responses to antiviral therapy. METHODS： Two hundred and eighty-four patients with chronic hepatitis C and 193 non-infected matched controls were included in this study. Patients were categorized according to their Scheuer score of hepatic fibrosis as F0-F2 （/7 = 202） or F3-F4 （/7 = 82） and according to their response to anti-Hepatitis C virus （HCV） therapy as sustained response （SR, n = 201） or non-sustained response （nSR, n = 98）. Genotyping of the -2518 （A/G） CCL2 was performed using PCR-RFLP, genotyping of the 190 （A/G） CCR2 using a PCR-ARMS system, and genotyping of the rs3138042 （G/A） CCR2 using Taqman probes. RESULTS： Univariate analyses identified 4 parameters （infection duration time, viral genotype, gender and AST levels） that tended to influence fibrosis and 7 parameters （CCL2G, CCL2ACCR2A, viremia levels, fibrosis stage, viral genotype, infection duration time and AST levels） that significantly influenced or tended to influence response to treatment. Multivariate analysis identified gender and AST levels as parameters that independently influenced fibrosis stage and viral genotype and infection duration time were the two parameters that independently influenced response to treatment. COnCLUSIOn： Our results indicate that the mutations studied in the gene pair CCL2/CCR2 do not play a major role in the outcome and response to treatment for HCV infection in the Spanish population.
