15 Aug 1997TL;DR: In this paper, a vegetable oil additive is derived from castor or lesquerella and the vegetable wax from jojoba or meadowfoam, which is suitable for use in internal combustion engines and in total loss applications.
Abstract: The vegetable oil based lubricant of the present invention is derived primarily from plants, a renewable resource. It is readily biodegradable via α- and β-oxidation utilizing microbes naturally present in the environment and is non-toxic to flora and fauna. The vegetable based lubricant of the invention includes a mono-, di- and trigycerol base oil making up the majority of the composition, a vegetable oil additive containing hydroxy fatty acids and a liquid vegetable wax. Additional antioxidants derived from natural vegetable or petroleum sources may be used. The base oil is primarily derived from the families Cruciferae, Leguminosae or Compositae. The vegetable oil additive is principally derived from castor or lesquerella and the vegetable wax from jojoba or meadowfoam. The invention is suitable for use in internal combustion engines and in total loss applications. The invention is designed as a total composition for its applications and is not an additive to petroleum lubricants.

TL;DR: In this article, the present value of electrochemical internal variables in a lithium-ion cell was estimated using readily available measurements of cell voltage, current, and temperature, using an extended Kalman filter along with a one-dimensional physics-based reduced-order model of cell dynamics.

TL;DR: To reconcile ecological reality with the application of tree-ring proxies for climate or environmental estimates, a clarification of the stationarity concept is provided, a simple confidence framework for the re-evaluation of existing studies is proposed and the use of a new statistical tool to detect non-stationarity in tree- ring proxies is recommended.
Abstract: Tree-ring records provide global high-resolution information on tree-species responses to global change, forest carbon and water dynamics, and past climate variability and extremes. The underlying assumption is a stationary (time-stable), quasi-linear relationship between tree growth and environment, which however conflicts with basic ecological and evolutionary theory. Indeed, our global assessment of the relevant tree-ring literature demonstrates non-stationarity in the majority of tested cases, not limited to specific proxies, environmental parameters, regions or species. Non-stationarity likely represents the general nature of the relationship between tree-growth proxies and environment. Studies assuming stationarity however score two times more citations influencing other fields of science and the science-policy interface. To reconcile ecological reality with the application of tree-ring proxies for climate or environmental estimates, we provide a clarification of the stationarity concept, propose a simple confidence framework for the re-evaluation of existing studies and recommend the use of a new statistical tool to detect non-stationarity in tree-ring proxies. Our contribution is meant to stimulate and facilitate discussion in light of our results to help increase confidence in tree-ring-based climate and environmental estimates for science, the public and policymakers.

TL;DR: In this article, Chakravarty et al. showed that line-soliton solutions of the Kadomtsev-Petviashvili II (KPII) equation can be classified by asymptotic information of the solution as $|y| \to \infty.
Abstract: In the previous papers (notably, Y. Kodama, J. Phys. A 37, 11169-11190 (2004), and G. Biondini and S. Chakravarty, J. Math. Phys. 47 033514 (2006)), we found a large variety of line-soliton solutions of the Kadomtsev-Petviashvili II (KPII) equation. The line-soliton solutions are solitary waves which decay exponentially in $(x,y)$-plane except along certain rays. In this paper, we show that those solutions are classified by asymptotic information of the solution as $|y| \to \infty$. Our study then unravels some interesting relations between the line-soliton classification scheme and classical results in the theory of permutations.
