Let f(x) be defined for 0≤x<∞ and let s denote an arbitrary real variable. . The Laplace transform of f(x) designated by either £{f(x)} or F(s), is. for all values of s for which the improper integral converges.. DiPrima. 9. th. . ed. , Ch . 6.3. : . Step . Functions .

The Earth Climate System is Ultimately in Contact with Our Astronomical Surroundings. Hale crater formed into an ice-rich terrain in the Early to middle Amazonian (Fig. 1) and is one of the youngest, largest (~125 km across), and best preserved craters on Mars. Discontinuous, initially water-rich deposits up to 450 km from Hale’s rim were ballistically emplaced and flowed for hours up to a day or two after impact (Figs. 1 and 2). The pristine nature of these deposits indicates: erosion rates were low after the Hale impact, Hale’s formation post-dates regional alluvial fan activity, and crater formation did not influence global or regional scale geomorphic activity or climate for any extended period of time..
