Discussion and analysis of a graduate recital: an examination of Gary Burton's "Chega De Saudade," Steve Reich's "Marimba Phase," Michael Gordon's "XY," John Cage's "In a Landscape," Minoru Miki's "Time for Marimba," and Milton Babbitt's "Homily"

Master's Project (M.Mu.) University of Alaska Fairbanks, 2017This paper discusses some of the many facets of percussion music through the examination and analysis of the following works: Gary Burton's Chega De Saudade for solo vibraphone; Steve Reich's Marimba Phase for two marimbas; Michael Gordon's XY for five drums; the author's own arrangement for multiple-percussion setup of John Cage's In a Landscape; Minoru Miki's Time for Marimba for solo marimba; and Milton Babbitt's Homily for solo snare drum. As the repertoire and performance practices of percussion continue to develop, there are many issues of note to the studying percussionist. These range from technical concerns, to issues of interpretation. Each work exemplifies certain of these issues, and this paper seeks to glean better understanding of those through analysis and study of the works

Dollarization and Euroization in Transition Countries: Currency Substitution, Asset Substitution, Network Externalities and Irreversibility

We examine the extent, causes and consequences of transition countries’ use of foreign currency as a co-circulating medium of exchange and store of value. Using new estimates of foreign cash in circulation, we obtain unique measures of currency substitution, asset substitution, and dollarization, and examine the consequences of network externalities for hysteresis and irreversibility. Finally, we examine factors leading some transition countries to euroize officially and bilaterally, and others to euroize unilaterally - that is, without prior sanction by the EMU.dollarization, euroization, transition economies, currency substitution, asset substitution, foreign currency, network externalities, irreversibility, underground economy

Tractable nonlinear memory functions as a tool to capture and explain dynamical behaviours

Mathematical approaches from dynamical systems theory are used in a range of fields. This includes biology where they are used to describe processes such as protein-protein interaction and gene regulatory networks. As such networks increase in size and complexity, detailed dynamical models become cumbersome, making them difficult to explore and decipher. This necessitates the application of simplifying and coarse graining techniques in order to derive explanatory insight. Here we demonstrate that Zwanzig-Mori projection methods can be used to arbitrarily reduce the dimensionality of dynamical networks while retaining their dynamical properties. We show that a systematic expansion around the quasi-steady state approximation allows an explicit solution for memory functions without prior knowledge of the dynamics. The approach not only preserves the same steady states but also replicates the transients of the original system. The method also correctly predicts the dynamics of multistable systems as well as networks producing sustained and damped oscillations. Applying the approach to a gene regulatory network from the vertebrate neural tube, a well characterised developmental transcriptional network, identifies features of the regulatory network responsible dfor its characteristic transient behaviour. Taken together, our analysis shows that this method is broadly applicable to multistable dynamical systems and offers a powerful and efficient approach for understanding their behaviour.Comment: (8 pages, 8 figures

Q&A: What are exosomes, exactly?

Exosomes are extracellular vesicles first described as such 30 years ago and since implicated in cell-cell communication and the transmission of disease states, and explored as a means of drug discovery. Yet fundamental questions about their biology remain unanswered. Here I explore what exosomes are, highlight the difficulties in studying them and explain the current definition and some of the outstanding issues in exosome biology.Wellcome Trus

Q&A: What are exosomes, exactly?

Abstract Exosomes are extracellular vesicles first described as such 30 years ago and since implicated in cell–cell communication and the transmission of disease states, and explored as a means of drug discovery. Yet fundamental questions about their biology remain unanswered. Here I explore what exosomes are, highlight the difficulties in studying them and explain the current definition and some of the outstanding issues in exosome biology
