A facile one-pot hydrothermal strategy was proposed to prepare ultrathin α-Co(OH) 2 nanosheets with a thickness of ca. 10 nm. Electrochemical data demonstrated that the ultrathin Co(OH) 2 nanosheets delivered a specific capacitance of 401 F g -1 at a current density of 0.67 A g -1, and even 232 F g -1 at 10 A g -1. A specific capacitance degradation is ca. 2% after 1000 continuous cycling at 4 A g -1. The desirable electrochemical performance of the ultrathin nanosheets mainly stems from the large interfacial area of solid/liquid reaction due to their large interlayer spacing and ultrathin nature, indicating that the ultrathin α-Co(OH) 2 nanosheets are a good candidate for electrochemical capacitor application. © 2012 Elsevier B.V.

We present a general framework for incorporating astrophysical information into Bayesian parameter estimation techniques used by gravitational wave data analysis to facilitate multi-messenger astronomy. Since the progenitors of transient gravitational wave events, such as compact binary coalescences, are likely to be associated with a host galaxy, improvements to the source sky location estimates through the use of host galaxy information are explored. To demonstrate how host galaxy properties can be included, we simulate a population of compact binary coalescences and show that for ∼8.5% of simulations within 200 Mpc, the top 10 most likely galaxies account for a ∼50% of the total probability of hosting a gravitational wave source. The true gravitational wave source host galaxy is in the top 10 galaxy candidates ∼10% of the time. Furthermore, we show that by including host galaxy information, a better estimate of the inclination angle of a compact binary gravitational wave source can be obtained. We also demonstrate the flexibility of our method by incorporating the use of either the B or K band into our analysis. © 2014. The American Astronomical Society. All rights reserved.

To solve the resource planning and scheduling technology of payload problem by optimizing the scheme of the resources on satellite to complete the missions excellently, this paper introduced a bio-inspired evolutionary derived from the simulation of the evolution of the plasmodium, which was named as Plasmodium Evolutionary Algorithm (PEA). In PEA, the both the schizogamy and sexual propagation were employed. In the schizogamy, individuals will proliferate with monomer variation to perform local search, while in the sexual propagation, the chromes will cross over to perform global search. With the resource planning and scheduling technology of payload problem was modeled to a combinatorial optimization problem, PEA has been employed to solve a simulation case. By comparisons with other evolutionary algorithms, the simulation results have shown the feasibility and effectiveness of PEA.

Using a fully classical model, we have studied sequential double ionization (SDI) of argon driven by elliptically polarized laser pulses at intensities well in the over-barrier ionization region. The results show that ion momentum distributions evolve from the two-band structure to the four-band, six-band structure and finally to the previously obtained four-band structure as the pulse duration increases. Our analysis shows that the evolution of these band structures originates from the pulse-durationdependent multiple ionization bursts of the second electron. These band structures unambiguously indicate the subcycle electron emission in SDI. © 2015 Optical Society of America.

Uniform design and partial least squares regression were adopted to quantitatively analyze the effects of plant oil and fatty acid as well as their addition amount and addition time on the performance of Tuber melanosporum submerged fermentation. The regression models showed the optimal scheme was the addition of 1.2 mL soybean oil on day 9, which was validated by experiment. The maximal biomass of 25.89∈±∈1.01 g/L and extracellular polysaccharides (EPS) production of 6.51∈±∈0.68 g/L were obtained, which were enhanced by 18.5% and 86%, respectively. Palmitic acid was identified to be the key component to stimulate the cell growth and EPS biosynthesis, and stearic acid was beneficial for the production of intracellular polysaccharides. Not only the biomass but also EPS production obtained in this work are the highest reported in the batch fermentation of truffle. © 2010 Springer-Verlag.
