Juglans californica shell that is difficult to remove. The Chumash Indians of the Channel Islands of California and Ventura County eat the nuts; however, they are not grown commercially for this purpose. "Juglans californica" is cultivated throughout California to support the walnut industry, used as a rootstock in English walnut orchards. It is also cultivated as an ornamental tree where it is planted in California native plant, xeriscape, and wildlife habitat gardens and natural landscaping in California, and in Hawaii. Some authorities (e.g. the California Native Plant Society) combine this species with "J. hindsii". On the other hand, a 2007 molecular analysis
Two-sided Laplace transform notation for the two-sided transform; the formula_3 used here recalls "bilateral". The two-sided transform used by some authors is In pure mathematics the argument "t" can be any variable, and Laplace transforms are used to study how differential operators transform the function. In science and engineering applications, the argument "t" often represents time (in seconds), and the function "ƒ"("t") often represents a signal or waveform that varies with time. In these cases, the signals are transformed by filters, that work like a mathematical operator, but with a restriction. They have to be causal, which means that the output in a
