We investigate the hole-doped antiferromagnetic state in a two-orbital model of cuprates. The model also includes d3z2−r2 orbital. Unlike the one-orbital model, we find the antiferromagnetic state stable against the hole doping for the cuprates with orbital splitting between dx2−y2 and d3z2−r2 orbitals being ∼1 eV. This results from the fact that t...

Background: The results of studies examining the response to experimental pain during the menstrual cycle are conflicting because of differences in the definitions of the menstrual period, outcome measures and types of experimental pain stimulation. So far, there have been only a few studies correlating experimental pain with the levels of gonadal ...
Coke-oven gas and Linz Donawitz gas are pollutive by-product gases generated from steel plants. The gases are currently combusted or released to atmosphere, but those can be economically utilized as chemical product. Thus, this study proposes improved methanol production process from the gases, by considering two different strategies: efficiency (C...
Electrochemical reduction of carbon dioxide (CO2) is a promising method toward carbon recycling. Highly selective bimetallic catalysts have been extensively demonstrated, while efforts to understand the compositional and geometrical effects have been limited. Here, we studied the relationship between the catalytic activity of bimetallic Cu-Sn catal...
We investigate the dynamics of aggressive order in the financial market to further understand volatility. To analyze aggressive order, market orders in the order book are scrutinized. The market orders have different degrees of aggressiveness; therefore, we categorize market orders into four types: types Zero, One, A, and B, of which type B is the ...
Using calculations from first principles, the site disorder between Ga and Zn of crystalline InGaZnO 4 is shown to play key roles in its unique transport properties. The analysis based on Density Functional Theory reveals that the various types of scattering centers stem from the charge imbalance between the ordered and disordered structures are th...
We report the reduction of thermal conductivity and phonon mean-free-path below the Casimir limit originated by phonon backscattering in silicon nanowires with scallop shaped surface modulation. The scallop surface modulation with a period of 55-110nm on 200nm diameter nanowires was created using top-down deep-reactive-ion-etching. The measured the...
Flexible materials with sufficient mechanical endurance under bending or folding is essential for flexible electronic devices. Conventional rigid materials such as metals and ceramics are mostly brittle so that their properties can deteriorate under a certain amount of strain. In order to utilize high-performance, but brittle conventional materials...
This paper proposes a new active noise control (aNC) system based on a recursive least-squares lattice (RLSL) algorithm by designing secondary-path innovation (SPI) and lattice-order decision (LOD) algorithms. The SPI algorithm associated with the power spectral factorization of the secondary path is designed to apply the RLSL algorithm to the aNC ...
A quantitative real-time polymerase chain reaction (QPCR) was applied to estimate biokinetic coefficients of Clostridium cadaveris and Clostridium sporogenes, which utilize protein as carbon source. Experimental data on changes in peptone concentration and 16S rRNA gene copy numbers of C. cadaveris and C. sporogenes were fitted to model. The fourth...
