XTS: A Mode of AES for Encrypting Hard Disks
IEEE Security & Privacy Magazine, 2010The IEEE Security in Storage Working Group (SISWG) has developed the XTS mode of the Advanced Encryption Standard (AES) that the IEEE 1619-2007 standard defines. (XTS stands for XEX-based tweaked codebook mode with ciphertext stealing.) This mode works within the constraints of hard disks while keeping the security that the AES algorithm provides.

Critical dynamics near a hard mode instability
Zeitschrift f�r Physik B Condensed Matter, 1981Scaling hypothesis and a renormalization group procedure are formulated in the vicinity of the bifurcation point, where the behaviour is governed by inhomogeneous fluctuations. The working of the general ideas is illustrated in a model system in which the number of components of the complex order parameter field goes to infinity.

Hard-aperture Kerr-lens mode locking
Journal of the Optical Society of America B, 1993Self-focusing by a Kerr nonlinearity in combination with an intracavity aperture creates a power-dependent loss in lasers, which has been used as a method for passive mode locking of lasers. An analytical treatment is presented that yields closed-form expressions for the modulation efficiency.

The effect of hard mode locking in a dye laser
Optical and Quantum Electronics, 1981The influence of the relaxation time of a saturable absorber on the dynamics of a quasi-continuous ring laser is investigated. It is shown that in a dye laser with a fast absorber, bistability arises; thus two multimode regimes coexist. The regime of shallow stochastic modulation is established spontaneously.

Hard Mode Spectroscopy of Phase Transitions
Reviews in Mineralogy and Geochemistry, 2000Phonon spectra respond, in principle, to any change of the crystal structure or lattice imperfections of a material. Traditionally optical soft modes, which can show relatively large variations, have been widely used for the analysis of displacive phase transitions.

Modes of Extrapolation: The Formulas of Hard SF
Science Fiction Studies, 1993Like other popular artforms, science fiction is “formulaic,” but its formulas, ranging from myth to mathematics, cannot be determined simply by era, setting, type of plot, or conventional values. As a form of fantasy, SF uses exaggeration, inversion, and extension as points of relevance to readers focused on the here and now.

Discrete relaxation modes for a hard-sphere gas
Canadian Journal of Physics, 1968The discrete spectrum of a linearized Boltzmann equation for a hard-sphere gas is studied, and the results of Kuščer and Williams (1967) for a spherically symmetric state are rederived by a more elementary method. Extension is made to nonisotropic states, and it is shown that the discrete spectrum is empty for [Formula: see text].

Perceived Hardness by Tapping: The Role of a Secondary Mode of Vibration
2017Humans can discriminate among the hardness of objects by tapping their surfaces. The damped natural vibration caused by tapping and its frequency are known to be the cue for the perception of hardness. This study is an investigation of the characteristics of this perception of hardness, as induced by vibration stimuli including multiple frequency ...

Hard mode stationary states generated by fluctuations
Zeitschrift f�r Physik B Condensed Matter and Quanta, 1978The influence of the fluctuations on the dynamics of open macroscopic systems is analysed for a class of two dimensional examples. The amplitudes of the fluctuations are themselves dependent on the macro-variables. It is shown that such random noises can generate temporal oscillations of the macro-variables.

Deviatoric and hydrostatic mode interaction in hard and soft tissue
Journal of Biomechanics, 1990It has been established that many hard and soft tissues have anisotropic material symmetry. It is noted here that the deviatoric and hydrostatic modes interact with each other in a general anisotropic elastic material. In the special case of isotropic, linear elastic, materials these modes are non-interactive.
