Performance of the MDSINE inference algorithms on simulated data with different sequencing depths. Simulations assumed an underlying dynamical systems model with ten species observed over 30 days with 27 time points sampled and an invading species at day 10. Performance of the four MDSINE inference algorithms, maximum likelihood ridge regression (MLRR), maximum likelihood constrained ridge regression (MLCRR), Bayesian adaptive lasso (BAL), and Bayesian variable selection (BVS), were compared. Algorithm performance was assessed using four different metrics: (a) root mean-square error (RMSE) for microbial growth rates; (b) RMSE for microbial interaction parameters; (c) RMSE for prediction of microbe trajectories on held-out subjects given only initial microbe concentrations for the held-out subject; and (d) area under the receiver operator curve (AUC ROC) for the underlying microbial interaction network. Lower RMSE values indicate superior performance, whereas higher AUC ROC values indicate superior performance. (PDF 182 kb

On Engetsu Sappo Ⅱ : Why is it effective?

柴田錬三郎が生み出した戦後時代小説最大級のヒーロー、眠狂四郎。その必殺剣、刀身をゆるやかに旋回させることによって、対手を一瞬の眠りに陥らしむる魔技「円月殺法」について、テキストの背後に存在する典拠史料の情報との比較考察を行う。柴錬は、当時の剣豪小説における「正しい剣」とされた無想剣をアレンジし、彼我の心境を逆転させ、敵を無想の境地に導く剣として、円月殺法を造形した。描写上利用された典拠、一刀流の剣術書における、「水月」および「卍」の理念が、円月殺法の性格や描写を決定づけたが、それは同時に、円月殺法の方向性を定めるものでもあった。空間に描かれる表象を、敵に視覚を媒介として認識させ、その精神を無想へと導く円月殺法は、正剣に対する邪剣として造形されたが、それが最終的に独自のヒューマニズムを発現させる物語の展開は、先の史料を典拠に用いた時点で、あらかじめ運命づけられていた

Simultaneous measurement of beta(-) decay to bound and continuum electron states

We report the first measurement of a ratio lambda(beta b)/lambda(beta c) of bound-state (lambda(beta b)) and continuum-state (lambda(beta c)) beta(-)-decay rates for the case of bare Tl-207(81+) ions. These ions were produced at the GSI fragment separator FRS by projectile fragmentation of a Pb-208 beam. After in-flight separation with the B rho-Delta E-B rho method, they were injected into the experimental storage-ring ESR at an energy of 400.5A MeV, stored, and electron cooled. The number of both the Tl-207(81+) ions and their bound-state beta(-)-decay daughters, hydrogenlike Pb-207(81+) ions, were measured as a function of storage time by recording their Schottky-noise intensities. The experimental result, lambda(beta b)/lambda(beta c)=0.188(18), is in very good agreement with the value of 0.171(1) obtained from theory employing spectra of allowed transitions.textapplication/pdfjournal articl

Synthesis and Regeneration of Ni-Phyllosilicate Catalysts Using a Versatile Double-Accelerator Method: A Comprehensive Study

Nickel phyllosilicate materials were usually prepared by the conventional hydrothermal method under severe conditions and ammonia evaporation method with unavoidable ammonia emission. To address these problems, a versatile double-accelerator method was proposed in this work, which could successfully synthesize nickel phyllosilicates through the hydrothermal treatment of silica and nickel nitrate at a quite low temperature of 40 °C or in an open system at 80 °C without autogenous pressure assisted by ammonium fluoride (NH4F) and urea. NH4F could accelerate the etching of silica to form the intermediate H4SiO4, and urea could facilitate the formation of a Ni­(OH)2 intermediate, resulting in the quick formation of Ni-phyllosilicates. In addition, this method exhibited high universality to prepare various metal (Ni, Co, and Cu) phyllosilicates, and both silica materials and sodium metasilicate could be the potential silicon-containing precursors to prepare Ni-phyllosilicates. Furthermore, the sintered Ni/SiO2 catalyst could also be regenerated after in situ acid pickling and double-accelerator synthesis without decline of catalytic activity. The optimal Ni-phyllosilicate catalyst (N/D-120-12) prepared by the double-accelerator method exhibited a high CO2 conversion of 78.4% and a CH4 yield of 74.5% at 400 °C, which also obtained a low Ea of 63.93 kJ·mol–1 and a high TOFCO2 (160 °C) of 3.1 × 10–2 s–1 for CO2 methanation. In situ DRIFTS results demonstrated that the presence of more m-HCOO– species on N/D-120-12 resulted in its high catalytic performance. Moreover, N/D-120-12 also exhibited high long-term and hydrothermal stability with an excellent anti-sintering property

Three-Dimensional Networked Ni-Phyllosilicate Catalyst for CO₂ Methanation: Achieving High Dispersion and Enhanced Stability at High Ni Loadings

It is a great challenge for nickel-based catalysts to obtain high-temperature stable Ni nanoparticles with high dispersion at high loadings. To address this problem, a group of three-dimensional (3D) networked nickel phyllosilicate catalysts were prepared through the hydrothermal reaction of 3D-SBA-15 and soluble nickel salts (Ni­(NO3)2 or Ni­(CH3COO)2) and were used for the CO2 methanation reaction to produce CH4 (substitute natural gas). The flower-like nanosheets corresponding to Ni3Si2O5(OH)4 are uniformly generated on the surface of 3D-SBA-15 and become much denser with increasing hydrothermal time, with Ni contents varying in the range of 24.22–30.72 wt %. Upon 750 °C reduction of phyllosilicate materials, small-sized Ni particles (<5 nm) can highly disperse and be confined into the silica and unreduced phyllosilicate support due to the strong interaction of the nickel and complex support. In addition, a Ni/3D-SBA-15 catalyst with the high Ni content of 30 wt % was also synthesized for comparison by an incipient wetness impregnation method. For the CO2 methanation reaction, the fabricated phyllosilicate catalyst achieved a higher maximum CH4 yield of 80.4% at 400 °C and exhibited a higher long-term stability of 100 h as compared to the impregnated sample. It was noted that the phyllosilicate catalyst also exhibited high hydrothermal stability at 600 °C under 100% steam. The enhanced catalytic performance was attributed to the excellent property of nickel phyllosilicate and the special pore structure derived from 3D-SBA-15, which could significantly improve the Ni dispersion and increase CO2 adsorption and H2 uptake as well as the interaction of nickel–support
