Post-quantum Security of the CBC, CFB, OFB, CTR
... 2 . Thus, all we need to show is that replacing one block of the challenge ciphertext by randomness leads to a negligible change in the advantage of the adversary. The situation is depicted in Figure 1 (b). – Say we want to show that c2 = H(m2 ⊕ c1 ) is indistinguishable from random (the situation i ...

... Humans have, as far as known, kept track of time, or cyclic events, since the beginning of development. To measure time, a reference oscillator is needed. It is impossible to measure time itself. It is only possible to measure a frequency or duration. In time measurement, it is assumed that two iden ...

HOMOGENEOUS LINEWIDTH AND SPECTRAL
... These studies provide important information on decoherence processes in nanocrystals. SHB response obtained from spherical CdSe/ZnS QDs exhibits a sharp ZPL and discrete acoustic phonon sidebands due to phonon-assisted transitions. The suppression of effects of spectral diffusion in the SHB measurem ...

Efimov Trimers under Strong Confinement
... 0 κ =m, with n a positive integer and λ0 ≃ 22.7 [1]. A more natural quantity to consider in the coldatom context is the scattering length a− < 0 at which the deepest Efimov trimer crosses the three-atom continuum: This crossing leads to an enhanced three-body loss rate in the Bose gas, which is th ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
