Pump-and-Probe Coincidence Momentum Imaging Evolution of Nuclear Wavepacket in CS2"1"... 

By defining a norm defining the distance between two signals, one can easily spot its variations. This distance provides an image of the signal evolution. Signals are typically Lissajous ( orbits ), i.e. arrays 2 of successive complex-valued points... 

Figure A3.13.7. Continuation of the time evolution for the CH eln-omophore in CHF after 90 fs of irradiation (see also figure A3,13,6). Distanees between tire eontoiir lines are 10, 29, 16 and 9 x 10 rr in the order of the four images shown. The averaged energy of the wave paeket eorresponds to 9200 em (roughly 6300 em absorbed) with a quantum meehanieal imeertainty of +5700 enC (from [97]).

FIG. 24 Evolution of the shape and size of the water structures formed after a tip contact of 5 seconds on freshly cleaved mica. The SPFM images were acquired, from top left to bottom right, at 5, 30, 50, 70, 130, and 150 minutes after formation. (From Ref. 51.)...

Fig. 1. SEM images of etched HfN surface in Cb with etching time (a) 10s, (b) 15s, (c) 20s, and (d) 25 s. The inset shows an evolution of surface topography (height) using AFM with various etching time X 0.25 um/div, Z 70nm/div. The experiments were performed at a pressure of lOmTorr, source power of 400W, and bias voltage of -200V.

How pectic signals were transduced was unknown, but information suggested that cytosolic free Ca might be involved [22]. Fluorescence ratio imaging has then been used to follow the evolution of free calcium concentrations ([Ca " ] ) after stimulation of carrot protoplasts by oligogalacturonides [23]. 

Fig. 4.2.5 Unaliased (A) and aliased (B) velocity images for a 0.6% aqueous carboxy-methylcellulose solution obtained by MRI. The vertical axes represent the data obtained in the velocity encoded direction and the horizontal axis represents data obtained in the spatially encoded direction. Aliasing is achieved by setting the velocity encode gradients so large that the maximum phase evolution of a given fluid element for a pulsed gradient step exceeds Ji or 2jt...
