Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We present an elastic model to explain the temperature-induced surface transitions observed on the spontaneous orientation of nematic liquid crystals on solid surfaces. The destabilizing effect is due to the mixed splay-bend curvature elasticity K13. The transition is temperature driven by the change in the nematic-liquid-crystal order parameter S. The transition is continuous. A large angular variation localized close to the boundary is predicted. Analyzing experimental data, we estimate aK13a-a10-7 cgs units. © 1993 The American Physical Society.
