Estimation of potential wildfire behavior characteristics to assess wildfire danger in southwest China using deep learning schemes.

Accurate estimation of potential wildfire behavior characteristics (PWBC) can improve wildfire danger assessment. However, wildfire behavior has been estimated by most fire spread models with immeasurable uncertainties and difficulties in large-scale applications. In this study, a PWBC estimation model (named PWBC-QR-BiLSTM) was proposed by coupling the Bi-directional Long Short-Term Memory (BiLSTM) and quantile regression (QR) methods.

Effect of needle diameter, type and volume of contrast agent on intervertebral disc degeneration in rats with discography.

Purpose: Discography can increase disc degeneration, but the influence of different discography variables on the degeneration of discs has not been reported. The aim of this study was to investigate the effects of discography variables of needle diameter, type of contrast agent and volume of contrast agent on disc degeneration.

Methods: Three separate experiments examined needle diameter, and type and volume of contrast agent.

Se@SiO nanocomposites suppress microglia-mediated reactive oxygen species during spinal cord injury in rats.

Selenium (Se) is an essential trace element with strong antioxidant activity, showing a great prospect in the treatment of spinal cord injury (SCI). However, the narrow gap between the beneficial and toxic effects has limited its further clinical application. In this experiment, we used porous Se@SiO nanocomposites (Se@SiO) modified by nanotechnology as a new means of release control to investigate the anti-oxidative effect in SCI.
