TL;DR: In this paper, the structural and electronic properties of silicon−carbon nanotubes (SiCNTs) were investigated and the trend from C-rich to Si-rich SiCNT was examined.
Abstract: Ab initio methods are used for investigating structural and electronic properties of silicon−carbon nanotubes (SiCNTs). Tubes with different Si to C ratios were tested and the trend from C-rich to Si-rich SiCNTs is examined. Our results show that SiCNTs lose stability when the ratio of Si over C increases. Nevertheless they remain stable until the ratio reaches 50:50, and after that the Si-rich tubes collapse to nanowires or clusters with solid interiors. The electronic density of states of different SiCNTs is also presented and analyzed.

TL;DR: Compared with beta-lactam monotherapy, the aminoglycoside/ beta- lactam combination was not associated with a beneficial effect on the development of antimicrobial resistance among initially antimicrobial-susceptible isolates.
Abstract: confidence interval [CI], 0.56‐1.47). Actually, b-lactam monotherapy was associated with fewer superinfections (OR, 0.62; 95% CI, 0.42‐0.93) and fewer treatment failures (OR, 0.62; 95% CI, 0.38‐1.01). Rates of treatment failure attributable to emergence of resistance (OR, 3.09; 95% CI, 0.75‐12.82), treatment failure attributable to superinfection (OR, 0.60; 95% CI, 0.33‐1.10), all-cause mortality during treatment (OR, 0.70; 95% CI, 0.40‐1.25), and mortality due to infection (OR, 0.74; 95% CI, 0.46‐1.21) did not differ significantly between the 2 regimens. Conclusions. Compared with b-lactam monotherapy, the aminoglycoside/b-lactam combination was not associated with a beneficial effect on the development of antimicrobial resistance among initially antimicrobialsusceptible isolates.

TL;DR: The hypothalamic-pituitary-adrenal (HPA) axis, when activated by stress, exerts an inhibitory effect on the female reproductive system, which is observed in anxiety and depression, malnutrition, eating disorders and chronic excessive exercise, and the hypogonadism of the Cushing syndrome as discussed by the authors.

TL;DR: It is concluded that structural equation modeling is a viable methodology to model complex regional interdependencies in brain activation in pediatric populations.
Abstract: The present study assessed the impact of sample size on the power and fit of structural equation modeling applied to functional brain connectivity hypotheses. The data consisted of time-constrained minimum norm estimates of regional brain activity during performance of a reading task obtained with magnetoencephalography. Power analysis was first conducted for an autoregressive model with 5 latent variables (brain regions), each defined by 3 indicators (successive activity time bins). A series of simulations were then run by generating data from an existing pool of 51 typical readers (aged 7.5-12.5 years). Sample sizes ranged between 20 and 1,000 participants and for each sample size 1,000 replications were run. Results were evaluated using chi-square Type I errors, model convergence, mean RMSEA (root mean square error of approximation) values, confidence intervals of the RMSEA, structural path stability, and D-Fit index values. Results suggested that 70 to 80 participants were adequate to model relationships reflecting close to not so close fit as per MacCallum et al.'s recommendations. Sample sizes of 50 participants were associated with satisfactory fit. It is concluded that structural equation modeling is a viable methodology to model complex regional interdependencies in brain activation in pediatric populations.
