We developed a scheme to investigate parity and time-reversal-odd order parameters associated with orbital currents within the framework of first-principle calculations. By applying our approach on CuO we further explore the source of orbital currents in this material which where observed by resonant x-ray diffraction. The comparison of our calculation with the experimental measurements reveale...

The extension of mathematical morphology to colour, and more generally to multivariate image data, continues to be an open problem. As its underlying theory is defined in terms of complete lattices, the main challenge lies in introducing a complete lattice structure on the image intensity range, hence vectorial extrema computation methods are necessary. In this paper, we circumvent the need for...

The result of a physical measurement depends on the time scale of the experimental probe. In solid-state systems, this simple quantum mechanical principle has far-reaching consequences: the interplay of several degrees of freedom close to charge, spin or orbital instabilities combined with the disparity of the time scales associated to their fluctuations can lead to seemingly contradictory expe...

Two or more are sometimes found to co-occur in both Taiwan and Mainland Mandarin Chinese, e.g., jiāyǐ and jìnxíng in duì xuéshēng jiāyǐ jìnxíng yǐndǎo ‘to guide students’, and a particular ordering is often preferred, e.g., jiāyǐ jìnxíng over jìnxíng jiāyǐ. This study argues that the order of the light verbs is closely associated to two kinds of information that the verbs specify, i.e. aspectua...

The extension of mathematical morphology to color and more generally to multivariate image data is still an open problem. The definition of multivariate morphological operators requires the introduction of a complete lattice structure on the image data, hence vectorial extrema computation methods are necessary. In this paper, we propose a lexicographical approach with this end, based on the pri...

We present a new low-complexity method for modeling and coding the bitplanes of a wavelet-transformed image in a fully embedded fashion. The scheme uses a simple ordering model for embedding, based on the principle that coeecient bits that are likely to reduce the distortion the most should be described rst in the encoded bitstream. The ordering model is tied to a conditioning model in a way th...

Nehring (2004) proposes an interesting methodology to extend the utilitarian criterion defined under complete information to an interim social welfare ordering allowing to compare acts. The first axiom defining his approach, called “State Independence,” requires the interim social welfare ordering to be consistent with ex-post utilitarian comparisons: if it is commonly known that the act f sele...

Nonlinear multichannel signal processing is an emerging research topic with numerous applications. In this paper we use the so-called reduced ordering (R-ordering) principle to introduce a new family of L lters for vector-valued observations. The coeecients of the proposed lters can be deduced so that the lters are optimal with respect to the output mean squared error. Expressions for the uncon...
