Light pyramid, shadow pyramid: Hispanic Baroque and radical complexity
2022The awareness that a sublunary world exists and, at the same time, that there is a divine principle in that same world, brings to the Spanish baroque system (and its various cohorts of legitimizers) into a modernity that becomes that of an epoch of radical complexity. The metaphor of the pyramids, which can be traced back to Nicholas of Cusa, expresses

Planar and pyramidal conformers of the alkali–ethylene complexes
Chemical Physics Letters, 2010Abstract Two geometric forms of the ethylene complex with an alkali atom are studied by ab initio methods. The lowest bound state of LiC 2 H 4 belongs to the B 2 point-group symmetry in the pyramidal conformer lying 0.20 eV higher than the dissociation asymptote into the ground state, while it is A 2 in the planar conformer lying 0.20 eV higher ...

One Kind of Network Complexity Pyramid with Universality and Diversity
2009It is based on well-known network models Euler graph, Erdos and Renyi random graph, Watts-Strogatz small-world model and Barabasi-Albert scale-free networks, and combined the unified hybrid network theoretical frame. One kind of network complexity pyramid with universality and diversity is constructed, described and reviewed.

Seismic migration using the complex shiftable pyramid
69th EAGE Conference and Exhibition - Workshop Package, 2007Seismic migration using the complex shiftable Pyramid Truong Nguyen (Ecole des Mines de Paris) and Herve Chauris (Ecole des Mines de Paris) SUMMARY____________________________________________________________ We consider how the 2-D seismic Kirchhoff migration scheme can benefit from a recently introduced shiftable directional pyramid.

Huge Magnetic Anisotropy in a Trigonal-Pyramidal Nickel(II) Complex
Inorganic Chemistry, 2013The work presented herein shows the experimental and theoretical studies of a mononuclear nickel(II) complex with the largest magnetic anisotropy ever reported. The zero-field-splitting D parameter, extracted from the fits of the magnetization and susceptibility measurements, shows a large value of -200 cm(-1), in agreement with the theoretical value ...

The Shiftable Complex Directional Pyramid—Part II: Implementation and Applications
IEEE Transactions on Signal Processing, 2008In Part I ["The shiftable complex directional pyramid-Part I: Theoretical Aspects," IEEE TRANSACTIONS on Signal Processing, vol. 56, no. 10, October 2008], we proposed a novel image decomposition called the shiftable complex directional pyramid. The shiftable, multiresolution and multidirectional image decomposition is constructed by the pyramidal dual-

A Nickel Complex Containing a Pyramidalized, Ambiphilic Pincer Germylene Ligand
Chemistry – A European Journal, 2019AbstractReaction of N‐heterocyclic carbene (NHC)‐stabilized PGeP‐type germylene Ge{o‐(PiPr2)C6H4}2⋅MeIiPr (1) (MeIiPr=1,3‐diisopropyl‐4,5‐dimethylimidazol‐2‐ylidene) with Ni(cod)2 gave pincer germylene complex Ni[Ge{o‐(PiPr2)C6H4}2](MeIiPr) (2), in which the Ge center of 2 is significantly pyramidalized.

The Third Side of the Pyramid – Task Complexity
2019This fifth main chapter illustrates the third and therefore last side of this thesis´ research pyramid. It does so by outlining a definition and distinctive categorization of tasks via a literature review. With this proviso, the first part of this chapter introduces a set of rules to differentiate five different task types.
