Creating an ambient intelligence network using insight and merged reality technologies

Humans live and work in environments which are essentially “dumb”, though recently, due to information networks, devices within these areas have increasingly become connected. The system presented here builds on previous work to create an ambient intelligence zone using facets of a merged reality system and a new process based on recognition/insight patterns. When combined, agents within the system communicate and react as one to form a responsive ambient intelligence at a given locatio

Deep immersion with Kasina: an exploration of meditation and concentration within virtual reality environments

The matching of established meditation techniques and new technologies offer intriguing possibilities for exploring how particular states of mind can be enhanced and become an inducible target. The Kasina method of developing meditation skills can be utilized for exploring and enhancing such states within VR. A comparison of various techniques is involved, together with virtual immersion, entrainment and biofeedback through EEG, also known here as Deep Immersion

Developing Web Applications

Building applications for the Internet is a complex and fast-moving field which utilizes a variety of continually evolving technologies. Whether your perspective is from the client or server side, there are many languages to master - X(HTML), JavaScript, PHP, XML and CSS to name but a few. These languages have to work together cleanly, logically and in harmony with the systems they run on, and be compatible with any browsers with which they interact. Developing Web Applications presents script writing and good programming practice but also allows students to see how the individual technolog

Characterisation of Cdkl5transcript isoforms in rat

CDKL5 deficiency is a severe neurological disorder caused by mutations in the X-linked Cyclin-Dependent Kinase-Like 5 gene (CDKL5). The predominant human CDKL5 brain isoform is a 9.7 kb transcript comprised of 18 exons with a large 6.6 kb 3′-untranslated region (UTR). Mammalian models of CDKL5 disorder are currently limited to mouse, and little is known about Cdkl5 in other organisms used to model neurodevelopmental disorders, such as rat. In this study we characterise, both bioinformatically and experimentally, the rat Cdkl5 gene structure and its associated transcript isoforms. New exonic regions, splice sites and UTRs are described, confirming the presence of four distinct transcript isoforms. The predominant isoform in the brain, which we name rCdkl5_1, is orthologous to the human hCDKL5_1 and mouse mCdkl5_1 isoforms and is the most highly expressed isoform across all brain regions tested. This updated gene model of Cdkl5 in rat provides a framework for studies into its protein products and provides a reference for the development of molecular therapies for testing in rat models of CDKL5 disorder

Using Stars, Not Just ‘Reading’ Them:The roles and functions of film stars in mother-daughter relations

This article explores the various and important ways in which film stars can function within mother-daughter relations over the life-cycle of their relationship. Drawing on detailed qualitative material from an interdisciplinary audience study of mothers’ and daughters’ shared relations to film stars, it demonstrates how a significant shift can be identified with regard to the kinds of roles that stars play in dyadic relations as a daughter experiences various developmental and transitional phases to adulthood. Necessitating an alternative approach to those previously employed within Star and Celebrity Studies, the article takes a significant new perspective on the study of audiences for stars from the work of art anthropologist Alfred Gell (1998) and proposes a move away from semiotic, ‘textualist’ readings of stars towards an ‘action’-centred exploration of the ways in which films stars are used and function in social interactions over the life-cycle of personal relationships

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. For example, a key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process versus those that measure fl ux through the autophagy pathway (i.e., the complete process including the amount and rate of cargo sequestered and degraded). In particular, a block in macroautophagy that results in autophagosome accumulation must be differentiated from stimuli that increase autophagic activity, defi ned as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (inmost higher eukaryotes and some protists such as Dictyostelium ) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the fi eld understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. It is worth emphasizing here that lysosomal digestion is a stage of autophagy and evaluating its competence is a crucial part of the evaluation of autophagic flux, or complete autophagy. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. Along these lines, because of the potential for pleiotropic effects due to blocking autophagy through genetic manipulation it is imperative to delete or knock down more than one autophagy-related gene. In addition, some individual Atg proteins, or groups of proteins, are involved in other cellular pathways so not all Atg proteins can be used as a specific marker for an autophagic process. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field

Characterisation of CDKL5 Transcript Isoforms in Human and Mouse

Mutations in the X-linked Cyclin-Dependent Kinase-Like 5 gene (CDKL5) cause early onset infantile spasms and subsequent severe developmental delay in affected children. Deleterious mutations have been reported to occur throughout the CDKL5 coding region. Several studies point to a complex CDKL5 gene structure in terms of exon usage and transcript expression. Improvements in molecular diagnosis and more extensive research into the neurobiology of CDKL5 and pathophysiology of CDKL5 disorders necessitate an updated analysis of the gene. In this study, we have analysed human and mouse CDKL5 transcript patterns both bioinformatically and experimentally. We have characterised the predominant brain isoform of CDKL5, a 9.7 kb transcript comprised of 18 exons with a large 6.6 kb 3’-untranslated region (UTR), which we name hCDKL5_1. In addition we describe new exonic regions and a range of novel splice and UTR isoforms. This has enabled the description of an updated gene model in both species and a standardised nomenclature system for CDKL5 transcripts. Profiling revealed tissue- and brain development stage-specific differences in expression between transcript isoforms. These findings provide an essential backdrop for the diagnosis of CDKL5-related disorders, for investigations into the basic biology of this gene and its protein products, and for the rational design of gene-based and molecular therapies for these disorders
