The clinico-neuroradiological syndrome posterior cortical atrophy is the cardinal ‘visual dementia’ and most common atypical Alzheimer’s disease phenotype, offering insights into mechanisms underlying clinical heterogeneity, pathological propagation and basic visual phenomena (e.g. visual crowding). Given the extensive attention paid to patients’ (higher order) perceptual function, it is surpri...

Vascular endothelial growth factor A (Vegfa) has important roles in endochondral bone formation. Osteoblast precursors, endothelial cells and osteoclasts migrate from perichondrium into primary ossification centers of cartilage templates of future bones in response to Vegfa secreted by (pre)hypertrophic chondrocytes. Perichondrial osteolineage cells also produce Vegfa, but its function is not w...

Different forms of metals and metalloids have varying degrees of toxicity in biological systems. Because of this, there has been an increase in the research focused on the speciation of metals at trace levels. Plasma mass spectrometric detection of hydride species has been established as a viable technique for the determination of these species at trace levels. One problem with the determinatio...

An infinite-dimensional version of Calogero-Moser operator of BC-type and the corresponding Jacobi symmetric functions are introduced and studied, including the analogues of Pieri formula and Okounkov’s binomial formula. We use this to describe all the ideals linearly generated by the Jacobi symmetric functions and show that the deformed BC(m, n) Calogero-Moser operators, introduced in our earl...

Introduction This chapter discusses using phenomenography to study information experience. Emphasizing the experiential nature of learning, Marton, Runesson, and Tsui (2004, p. 5) made the statement, " Powerful ways of acting spring from powerful ways of seeing. " This deceptively simple statement argues for the need for research that reveals the experiences (ways of seeing) of learners. It sug...

The European Pollen Database (EPD) is a community effort to archive and make available pollen sequences from across the European continent. Pollen sequences provide records that may be used to infer past vegetation and vegetation change. We present here maps based on 828 sites from the EPD giving an overview of changes in postglacial pollen assemblages in Europe over the past 15,000 years. The ...

DEDICATION To my family ii ACKNOWLEDGEMENTS As I come to the completion of one chapter of my life and prepare to begin the next, I reflect upon a quote I have carried with me throughout my graduate studies from the African-American educator and author Booker T. Washington-" Success is to be measured not so much by the position that one has reached in life as by the obstacles by which s(he) has ...

Using a new dataset encompassing more than 2,000 inventions made by Max Planck Society researchers from 1980 to 2004, we study the effects of information asymmetry and imperfect knowledge transfer on the licensing and successful commercialization of technologies from public research, distinguishing among types of licensees as well as invention and inventor characteristics. Technologies licensed...

The Israeli Chapter of the IEEE Computer Society has taken on the goal of promoting computer and software technology in Israel through study, research, and application. One of the distinctive features of the Israeli hi-tech industry is not only the sheer number of start-ups but also the large proportion of start-ups run by repeat entrepreneurs. It is instructive to compare America and Israel. I...
