The separation of concerns, as a conceptual tool, enables us to manage the complexity of the software systems that we develop. There have been a number of approaches aimed at modularizing software around the natural boundaries of the various concerns, including subject-oriented programming [Harrison & Ossher, 93], composition filters [Aksit & Bergmans, 1992], aspect-oriented programming [Kiczal...

Abstract: We study scattering of a composite quasiparticle, which possesses a degree of freedom corresponding to relative separation between two bound particles, by a delta-like impurity potential on a one-dimensional discrete lattice. Different from a composite object in continuum space, for a composite quasiparticle on a discrete lattice, the entanglement between its relative and centre of ma...

the research argues that the ending divine attributes of the quranic verses are related semantically to the verses’ theme. according to the content of the quranic verses, supported by some commentators, the ending divine attributes of the verses have such a deep semantic relationship with the verse content that if we abandon the ending attributes, some disorder is made in the verse theme. this ...

The visual system is concerned with the perception of objects in a dynamic world. A signi cant fact about natural time-varying images is that they do not change randomly over space-time; instead image intensities at di erent times and/or spatial positions are highly correlated. We measured the spatiotemporal correlation function { equivalently the power spectrum { of natural images and we nd th...

Strobe rearing prevents the convergence of inputs with different response timings onto area 17 simple cells. J. Neurophysiol. 80: 3005-3020, 1998. The preceding paper showed that the loss of direction selectivity in simple cells induced by strobe rearing reflects the elimination of spatially ordered response timing differences across the receptive field that underlie spatiotemporal (S-T) insepa...

1. Simple cells in cat striate cortex were studied with a number of stimulation paradigms to explore the extent to which linear mechanisms determine direction selectivity. For each paradigm, our aim was to predict the selectivity for the direction of moving stimuli given only the responses to stationary stimuli. We have found that the prediction robustly determines the direction and magnitude o...

In this work we describe a protocol by which two of three parties generate two bipartite entangled state among themselves without involving third party, from a non maximal W state or W type state |X〉 = α|001〉123+β|010〉123+γ|100〉123, α+ β+γ = 1 shared by three distant partners. Also we have considered the case β = γ, to obtain a range for α, for which the local output states are separable and no...

We argue that four service innovation mechanisms by Gallouj and Weinstein imply that services are modular offerings. In this comparative case study, we look at four knowledge-intensive business service innovations to further understand the nature of modularization in services. Our findings indicate that modularization was used primarily for systematization and innovation purposes, and the prefe...
