Re-exploration of the PHCCC Scaffold: Discovery of Improved Positive Allosteric Modulators of mGluR4

This paper describes a detailed structure activity relationship (SAR) analysis of the metabotropic glutamate receptor 4 (mGluR4) positive allosteric modulator, (-)-N-phenyl-7-(hydroxyimino)cyclopropa[b]-chromen-la-carboxamide (PHCCC). We have now developed compounds with improved potency and efficacy; in addition, compounds are presented that show selectivity for mGluR4 versus the other mGluR subtypes.

Re-imaging the Periphery: The Reproduction of Space in Cairo

This chapter examines Cairo’s path towards reassembling a modern spatial order in one of its oldest quarters, Bulaq Abul Ela, and the implications of this on the spatial experience of its inhabitants. The ambitions of space reproduction in Cairo are revealed during the attempt to engender a debate as to how this vision affected Bulaq’s riverfront zone as its periphery; how it was spatialised and to what extent the planners’ conception of urban space actually responded to the people’s needs when creating a new spatial reality. It uncovers the peripheral/central position that residents assume with regards to their living spaces to reveal new meanings, images, stories and places to replace the increasingly undesirable authentic fabric of Bulaq.

Clustered indexing for branch predictors

As a result of resource limitations, state in branch predictors is frequently shared between uncorrelated branches. This interference can significantly limit prediction accuracy. In current predictor designs, the branches sharing prediction information are determined by their branch addresses and thus branch groups are arbitrarily chosen during compilation. This feasibility study explores a more analytic and systematic approach to classify branches into clusters with similar behavioral characteristics. We present several ways to incorporate this cluster information as an additional information source in branch predictors.

Re-Stor(y)ing social change

New understandings arise as we encounter the emergent integration of both rational and emotional, physical and spiritual, masculine and feminine through imagination, myth, and storytelling. This expanded space fosters an iterative spiraling process whereby new personal and collective futures emerge from transformative possibilities. Contemplating love and the situatedness of our being creates a space for seeing differently, more inclusively. Thought Woman tells a story of encounters arising from contemplation, framing an emancipatory path toward wholeness and unity, being shaped through becoming, recognizing the interrelated web of life wherein humankind can flourish. Flourishing represents the central focus of the critical accounting project.

Enhanced approach for latent semantic indexing using wavelet transform

Latent semantic indexing (LSI) is a technique used for intelligent information retrieval (IR). It can be used as an alternative to traditional keyword matching IR and is attractive in this respect because of its ability to overcome problems with synonymy and polysemy. This study investigates various aspects of LSI: the effect of the Haar wavelet transform (HWT) as a preprocessing step for the singular value decomposition (SVD) in the key stage of the LSI process; and the effect of different threshold types in the HWT on the search results. The developed method allows the visualisation and processing of the term document matrix, generated in the LSI process, using HWT. The results have shown that precision can be increased by applying the HWT as a preprocessing step, with better results for hard thresholding than soft thresholding, whereas standard SVD-based LSI remains the most effective way of searching in terms of recall value.
