Juglans mandshurica Juglans mandshurica Juglans mandshurica, the Manchurian walnut, is a deciduous tree of the genus "Juglans" (section "Cardiocaryon"), native to the Eastern Asiatic Region (China, Russian Far East, North Korea and South Korea). It grows to about 25 m. The leaves are alternate, 40–90 cm long, odd-pinnate, with 7–19 leaflets, 6–17 cm long and 2–7.5 cm broad (margin serrate or serrulate, apex acuminate). The male flowers are in drooping catkins 9–40 cm long, the wind-pollinated female flowers (April–May) are terminal, in spikes of 4 to 10, ripening in August–October into nuts, 3-7.5 × 3–5 cm, with densely glandular pubescent green husk
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
