The "fish-bone" structure of the intercluster interaction introduced by Schmid is derived from first principles. It is shown that this structure does not depend on details of the cluster ground states, nor on the details of the microscopic interaction, and is therefore a-fundamental symmetry of interactions between composites. The derivation is based on a recently proposed microscopic method of...

The highly demanding study of meaning, intention, and communication including miscommunication, in human interaction seems to call for the development of powerful new approaches and in that context the astonishing raw power of modern computers may eventually be harnessed, given that adequate models, methods, algorithms and software be developed and made available. In this context, a proposed da...

It was ­ rst pointed out by Drell & Yan (1970) that parton model ideas developed for deep-inelastic scattering could be extended to certain processes in hadron{hadron collisions. The paradigm process, proposed by Drell & Yan, was the production of a massive lepton pair by quark{antiquark annihilation: the Drell{Yan process (illustrated in ­ gure 1). For the production of a lepton pair of invari...

In order to stress the importance of P300 responses in drug development, we describe the spatiotemporal characteristics of this objective, evoked event-related potential. These brain activations reflect mnemonic function, in which limbic structures play a role. It is demonstrated that a pharmacological challenge concerning, for example, the cholinergic system in young healthy volunteers induces...

– We present results of all-electron electronic structure calculations for the recently discovered d electron heavy fermion compound LiV2O4. The augmented spherical wave calculations are based on density functional theory within the local density approximation. The electronic properties near the Fermi energy originate almost exclusively from V 3d t2g states, which fall into two equally occupied...

background and objectives: knowledge management (km) has emerged as a pathway towards competitive advantage in current complex industrial environment. the aim of the present study was to explore the relationship between km effectiveness and various organizational factors including social interactions (trust, communication and coordination), infrastructure factors (structure, information technol...

The structure of N,N'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, C19H22N2O2, has been studied at low temperature (120K) by means of single-crystal X-ray diffraction. Solving the structure shows an orthorhombic unit cell, with P212121 space group, Z = 4, a = 6.1046 (4) Å, b = 15.8349 (11)</e...
