TL;DR: These guidelines include the evaluation of evidence for diagnostic and therapeutic procedures in managing chronic spinal pain and recommendations for managing spinal pain are described here to provide recommendations for clinicians.

TL;DR: In this article, chemical weather forecasting models are described and compared on regional and continental scales in Europe, and the most prominent gaps of knowledge are highlighted for the following selected focus areas: emission inventories, the integration of numerical weather prediction and atmospheric chemical transport models, boundary conditions and nesting of models, data assimilation of the various chemical species, improved understanding and parameterization of physical processes, better evaluation of models against data and the construction of model ensembles.

TL;DR: In this paper, a simple least squares linear regression was fitted to the annual number of tornado reports and the F1 and greater Fujita-scale record was used in determining a big tornado day.

TL;DR: This systematic review evaluating the effectiveness of SCS in relieving chronic intractable pain of failed back surgery syndrome indicated the evidence to be Level II-1 or II-2 for clinical use on a long-term basis.

TL;DR: In this article, a scale analysis shows that surface MFC is directly proportional to the horizontal mass convergence field, allowing MFC to be highly effective in highlighting mesoscale boundaries between different air masses near the earth's surface that can be resolved by surface data and appropriate grid spacing.
