This false color image, taken by NASA's Phoenix Mars Lander's Surface Stereo Imager, was taken on the 131st martian day, or sol, of the mission (October 7, 2008). The image shows color variations of the trench, informally named "La Mancha," and reveals the ice layer beneath the soil surface. The trench's depth is about 1.9 inches (5 cm) deep. The color outline of the shadow at the bottom of the image is a result of sun movement with the combined use of infrared, green, and blue filters. ...

... We have presented the chirplet transform, which may be viewed as a generalization of both the short-time Fourier transform (STFT) and the wavelet transform (WT). ... The Gaussian chirplet transform (GCT) results in a complex function of four variables: time, frequency, scale, and ``chirprate''. ... The full continuous chirplet transform (CCT) that can be obtained using only a single mother chirplet results in a complex function of five variables: time, frequency, scale, chirprate, and dispersionrate...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
