With years of development, SnTe as a homologue of PbTe has shown great potential for thermoelectric applications in p‐type conduction, and the most successful strategy is typified by alloying for maximizing the valence band degeneracy. Among the known alloy agents, MnTe has been found to be one of the most effective enabling a band convergence for an enhancement in electronic performance of SnTe, yet its solubility of only ~15 at% unfortunately prevents a full optimization in the valence band structure. This work reveals that additional PbTe alloying not only promotes the MnTe solubility to locate the optimal valence band structure but also increases the overall substitutional defects in the material for a substantial reduction in lattice thermal conductivity. In addition, PbTe alloying simultaneously optimizes the carrier concentration due to the cation size effect. These features all enabled by such a solute manipulation synergistically lead to a very high thermoelectric figure of merit, zT of ~1.5 in SnTe with a 20 at% MnTe and a 30 at% PbTe alloying (Sn0.5Mn0.2Pb0.3Te), demonstrating the effectiveness of solute manipulation for advancing SnTe and similar thermoelectrics.

Objective:This study aimed to analyze the interaction of Angiotensin II type 1 receptor (AT1R) gene polymorphism and occupational noise on the occurrence of essential hypertension (EH) in steel and iron enterprise men workers.Methods:A case control study of 935 iron and steel enterprise men workers was conducted, which included 312 cases of hypertension and 623 cases without hypertension. The noise at the workplace was assessed. Polymorphism of AT1R of the workers was examined using polymerase chain reaction - restriction fragment length polymorphism.Results:Polymorphism of AT1R (AC+CC vs. AA, odds ratio [OR] = 1.760, 95% confidence interval [CI]: 1.061∼2.920) and noise (greater than or equal to 85 dB(A),OR = 1.641, 95%CI: 1.225∼2.198) were independent determinants of EH using multivariate Logistic regression. Compared with AA carriers without noise, AC+CC interacted with noise (OR = 2.519, 95%CI: 1.254∼5.062) based on the multiplied model.Conclusions:AC+CC genotype of AT1R and noise were the risky factors of EH. These factors also interacted with each other.

Simulation of network protocol behavior in Vehicular AdHoc Network (VANET) scenarios is strongly demanded for evaluating the applicability of developed network protocols. In this work, we discuss the need for bidirectional coupling of network simulation and road traffic microsimulation for evaluating such protocols. The implemented mobility model, which defines all movement of nodes, influences the outcome of simulations to a great deal. Therefore, the use of a representative mobility model is essential for producing meaningful results. Based on these observations, we developed the hybrid simulation framework Veins (Vehicles in Network Simulation), composed of the network simulator OMNeT++ and the road traffic simulator SUMO. Based on a proof-of-concept study, we demonstrate the advantages and the need for bidirectionally coupled simulation.
