We present a combined theoretical and experimental study of the electronic structure stoichiometric ${\mathrm{Bi}}_{4}{\mathrm{Te}}_{3}$, natural superlattice alternating ${\mathrm{Bi}}_{2}{\mathrm{Te}}_{3}$ quintuple layers Bi bilayers. In contrast to related semiconducting compounds ${\mathrm{Bi}}_{1}{\mathrm{Te}}_{1}$, density functional theory predicts ${\mathrm{Bi}}_{4}{\mathrm{Te}}_{3}$ i...

Iron-doped bismuth sulphide (Bi2-xFexS₃) nanocrystals have been successfully synthesized in a glass matrix using the fusion method. Transmission electron microscopy images and energy dispersive spectroscopy data clearly show that nanocrystals are formed with an average diameter of 7-9 nm, depending on the thermic treatment time, and contain Fe in their chemical composition. Magnetic force micro...

We introduce the logic of bunched implications, BI, in which multiplicative (or linear) and additive (or intuitionistic) implications live side-by-side. We provide a truth conditional semantics, a proof theory and a categorical semantics of proofs. We explain how BI arises as a logic of resources and sketch a development of this computational interpretation, which is quite diierent from that of...

this article addresses the problem of balancing the time-cost-income aspects of talent management and succession in knowledge-based organizations. reviewing the literature figures out that many researches emphasize the importance of talent management and planning for succession. while the wide range of attracting talents from outside to fill this gap to train the inside talents to have a succes...

Bi-Hamiltonian structures are of great importance in the theory of integrable Hamiltonian systems. The notion of compatibility of symplectic structures is a key aspect of bi-Hamiltonian systems. Because of this, a few different notions of compatibility have been introduced. In this paper we show that, under some additional assumptions, compatibility in the sense of Magri implies a notion of com...

The application of multi-attribute utility theory based on the Choquet integral requires the prior identification of a capacity if the utility scale is unipolar, or of a bi-capacity if the utility scale is bipolar. In order to implement a minimum distance principle for capacity or bi-capacity approximation or identification, quadratic distances between capacities and bi-capacities are studied. ...

In this paper we explore how management of sustainability in organisations can be supported by business intelligence (BI) systems. We suggest that BI has an important role to play in helping organisations implement and monitor sustainable practices. We pay particular attention to one phase of any BI project, the information planning phase, i.e., the systematic way of defining relevant informati...

We describe an explicit simulation of 2-way nondeterministic automata by 1-way alternating automata with quadratic blow-up. We first describe the construction for automata on finite words, and extend it to automata on infinite words.
