Dhansak ("Dhan" is Persian/Urdu for "seed"- referring to grains or legumes; "Sak" (derived from Gujarati "shaak" meaning vegetable greens or cooked vegetables). The Gujarati element of the recipe is the liberal use of a variety of Indian spices and condiments, in contrast to the more mellow Iranian recipes. In Parsi homes, dhansak is traditionally made on Sundays owing to the long preparation time required to cook the lentils and vegetables into a mush (in the days before pressure cooking was employed). Dhansak is also always had on the fourth day after the death of a near one. There is no meat
Ultrashort pulse the amplitude of ultrashort pulses. To accurately control the pulse, a full characterization of the pulse spectral phase is a must in order to get certain pulse spectral phase (such as transform-limited). Then, a spatial light modulator can be used in the 4f plane to control the pulse. Multiphoton intrapulse interference phase scan (MIIPS) is a technique based on this concept. Through the phase scan of the spatial light modulator, MIIPS can not only characterize but also manipulate the ultrashort pulse to get the needed pulse shape at target spot (such as transform-limited pulse for optimized peak power, and other
