Angle-resolved resonant inelastic x-ray scattering from transition-metal magnetic ions
No full textWe present a study on the x-ray inelastic scattering at the 2p resonance of transition metals. The theoretical results are discussed in the single-ion model with crystal-field corrections and the full description of multiplet manifolds. The interference effects among the intermediate states are described as a function of the directions and polarizations of the incoming and outcoming beams. We consider the special case where the emission is due to inner-shell recombination. A variety of peculiar effects are discussed, with special reference to the perpendicular geometry of the incoming beam. The simplest cases are analytically examined showing the potential sensitivity of this technique to the electronic structure. Numerical results for the total and dichroic signals for some elements of the 3d series are given
The NK-1 Receptor Signaling: Distribution and Functional Relevance in the Eye
No full textNeurokinin-1 receptor (NK1R) signaling pathways play a crucial role in a number of biological processes in the eye. Specifically, in the ocular surface, their activity modulates epithelial integrity, inflammation, and generation of pain, while they have a role in visual processing in the retina. The NK1R is broadly expressed in the eye, in both ocular and non-ocular cells, such as leukocytes and neurons. In this review, we will discuss the roles of neurokinin-1 receptors and substance P (SP) in the physiopathology of eye disorders. Finally, we will review and highlight the therapeutic benefits of NK1R antagonists in the treatment of ocular diseases
Bonus-Malus Approach to Project Management
No full textThis paper concentrates on the management of delayed projects charged with penalty costs and of expedited projects rewarded with bonuses, based on an activity graph description of the projects. We propose a two-stage heuristic procedure to assist project managers to determine “fair” shares of penalties or compensations for agents involved when information regarding the project’s schedule and its actual execution is available. Incentives for better performance play a key role in this procedure, which combines a “bonus-malus” approach with a rationing approach. In the first stage, activities’ deviations from the schedule are computed using heuristic algorithms which implement incentives for better performance according to two alternative scenarios. In the second stage, the deviations of activities computed according to the chosen scenario are adjusted using well-known rules from the literature on rationing problems. A new family of compensations-penalties solutions, called Mutual Help Solutions, is introduced and illustrated
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textIn this note we represent a classical bankruptcy problem as a standard flow problem on a simple network and implement some known division rules from the bankruptcy literature via suitable cost functions in the related minimum cost flow problem
Conductance crossovers in coherent surface transport on y nanojunctions
No full textConductance characteristics of a nonplanar two-dimensional electron gas (2DEG) can expose the role of its bending on the 2DEG electronic states. In particular, the presence of an effective geometric potential can be revealed. Here, we present a numerical study of the coherent electron transport on Y nanojunctions of three cylindrical 2DEGs, including a proposal for the experimental detection of the geometric potential. We describe the analytical approach leading to the reduction of the problem dimensionality from 3D to 2D and sketch our simulation scheme. © 2009 IOP Publishing Ltd
