VLSI designs often show regular structures, where issues like temporal and spatial recursivity, and bidirectionality play a central role. This document introduces the modelling of a class of regular VLSI circuits, namely iterative systolic arrays, in a particular secondorder logic, and presents fully automatic veri cation of pipeline properties for an example from the literature.

Henry Tourneux, in his 2007 article “L’inversion tonale en kotoko” (Tourneux 2007) drew our attention on a phenomenon concerning systematic tone variations contrasting a Low and High final tone in the tone patterns of two dialects of Kotoko. A similar phenomenon was observed in our study of Geji, a Chadic language spoken in Bauchi State, Nigeria. This paper aims at documenting this variation an...

• Elaborate and build upon a growing body of sociological knowledge concerned with cultural resistance and oppositional cultures • Emphasise the significance of human agency in mediating progressive social change • Analyse the innovative ways in which subordinated minority social groups, in this case indigenous Australians, negotiate ‘bi-culturality’, that is, the interface between indigenous c...

We have recorded the 35 1 nm photoelectron spectra of Bi; , Bi; , and Bi; . The spectrum of Bi; shows transitions to at least seven electronic states of Bi, neutral, four of which are observed with vibrational resolution. Term energies, bond lengths, and vibrational frequencies are obtained for the anion ground state and for the first three excited states of Bi, . These results are compared to ...

In the present work, ZnO - SiO2 and Bi2O3– CuO nanocomposites have been prepared by sol gel with alternate precursors existing in literature. They are characterised by XRD, SEM,UV, FTIR and photoluminescence  spectra .The XRD results indicate a crystallite size of  approximately 80 nm for both nanocomposites. SEM image shows a heterogeneous particle size for bot...

we consider the fundamental relation  on a semihypergroup  to interpret the lower and upper approximations as subsets of the fundamental semigroup  and we give some results in this connection. also, we introduce the notion of a bi-hyperideal to study the relationship between approximations and bi-hyperideals.

Bi-factor analysis is a form of confirmatory factor analysis originally introduced by Holzinger. The bi-factor model has a general factor and a number of group factors. The purpose of this paper is to introduce an exploratory form of bi-factor analysis. An advantage of using exploratory bi-factor analysis is that one need not provide a specific bi-factor model a priori. The result of an explora...

Scavenger receptor BI (SR-BI) is an HDL receptor. It binds HDL and mediates the uptake of cholesteryl ester from HDL. Early studies have pointed out that the extracellular domain of SR-BI is critical for SR-BI-mediated cholesteryl ester uptake. However, the extracellular loop of SR-BI is large: it contains 403 amino acids. The HDL binding site and the modulation of SR-BI-mediated cholesteryl es...

In this paper, we initiate the study of prime bi-ideals (fuzzy bi-ideals) in semirings. We define strongly prime, prime, semiprime, irreducible and strongly irreducible bi-ideals in semirings. We also define strongly prime, semiprime, irreducible, strongly irreducible fuzzy bi-ideals of semirings. We characterize those semirings in which each bi-ideal (fuzzy bi-ideal) is prime (strongly prime).
