In this TREESPH code, hydrodynamic properties are determined using a Monte Carlo-like approach known as smoothed particle hydrodynamics (SPH). Unlike most previous implementations of SPH, gravitational forces are computed with a hierarchical tree algorithm. Multiple expansions are used to approximate the...

The C:N and C:P ratios of the leaves of Mediterranean shrubs and trees were also enhanced by drought32. Similar to our results, soil N:P ratios were found to be greater in meadow steppe than in desert steppe33 in Inner Mongolia. However, no effect of drought on bryophyte C:P ratios ...
and a questionnaire survey was administered to collect patients’ lifestyle habits. Time-dependent cox regression trees, event-free Kaplan–Meier curve, Mann–Whitely U test were used to analysis the results. The median follow-up time was 30 (12–60) months. Radiotherapy-related caries occurred...
