In the context of higher-dimensional cosmologies we study the conditions under which adiabatic expansion of the visible external space is possible, when a time-dependent internal space is present. The analysis is based on a reinterpretation of the four-dimensional stress-energy tensor in the presence of the extra dimensions. This modifies the usual adiabatic energy conservation laws for the vis...

The title compound, [Rh(C(17)H(15)Cl(2)N(2))(CO)(2)], is a rhodium(I) derivative of a β-diketiminato moiety. It is an example of a new type of β-diketiminate derivative that has not yet been characterized via solid-state methods. The complex crystallizes with a distorted square-planar geometry about the Rh(I) atom (m symmetry). A weak inter-molecular C-H⋯O contact is observed.

This paper deals with the presentation of a new microparts feeding system based on inertial force and able to move microcomponents with various shapes and sizes. It is a part of our microfactory project, in which different modular elements work together in order to perform assembly tasks [1], [2], [3], [4]. We present the design and the experimental results of this new type of feeder based on t...

Hopf insulators are characterized by a topological invariant called the Hopf index which classifies maps from three-sphere to two-sphere, instead of a Chern number or a Chern parity. In contrast to a topological insulator, the Hopf insulator is not protected by any kind of symmetry. By dimensional reduction, we argue that there exists a new type of Z(2) index for 2D Hamiltonian with a vanishing...

Abstract The sequence spaces c and cs have recently been introduced in [13] and [9], respectively, as the sets of all sequences whose Λ− transforms are in the spaces c and cs, respectively. The main purpose of this study is to introduce the new type cores, KΛ− core and SΛ− core, of a real valued sequence and also determine necessary and sufficient conditions for a matrix A to satisfy KΛ − core(...

This research is an investigation of Web-based periodicals, an emerging cultural form that presents magazine content in an electronic medium. Specifically, we compare and evaluate the characteristics of incumbent producers that publish Web-based complements to existing paper publications, and newcomer producers that publish Web-based documents exclusively. Drawing on evolutionary perspectives f...
