An electron-emitting device comprises a pair of oppositely disposed electrodes and an electroconductive film inclusive of an electron-emitting region arranged between the electrodes. The home location register maintains the mobile subscriber data and a message is sent to the home location register for requesting the mobile subscriber data. The invention makes an analogy between real measured data and transformed Monte Carlo generated computer data and then applies data denoising techniques to reduce the noise in the Monte Carlo dose images. Furthermore, the first side electrode and the second side electrode are respectively extended to four surfaces adjacent and perpendicular to the two side surfaces. Compounds of formula I are agonists and antagonists of neuropeptide Y, and are therefore useful as regulators. A porous film with highly uniform small pores and a desired porosity profile can be obtained with this method.
