Territories, Environments, Politics : Explorations in Territoriology

This collection seeks to illustrate the state of the art in territoriological research, both empirical and theoretical. The volume gathers together a series of original, previously unpublished essays exploring the newly emerging territorial formations in culture, politics and society.While the globalisation debate of the 1990s largely pivoted around a ‘general deterritorialisation’ hypothesis, sin

High-throughput spectroscopy of semiconductor nanowires in the presence of inhomogeneity

Controllable doping in semiconductor nanowires is essential for development of optoelectronic devices. Despite great progress, a fundamental challenge remains in controlling the uniformity of doping, particularly in the presence of relatively high levels of geometrical inhomogeneity in bottom-up growth. A relatively high doping level of 1E18 cm-3 corresponds to just ~1000 activated dopants in a 2µ

Chemically Recyclable Poly(β-thioether ester)s Based on Rigid Spirocyclic Ketal Diols Derived from Citric Acid

Incorporating rigid cyclic acetal and ketal units into polymer structures is an important strategy towards high-performance materials from renewable resources. In the present work, citric acid, a widely used platform chemical derived from biomass, has been efficiently converted into diand tricyclic diketones. Ketalization with glycerol or trimethylolpropane afforded rigid spirodiols, which were ob

TrueTime : Simulation Tool for Performance Analysis of Real-Time Embedded Systems

Embedded systems and networked embedded systems play an increasingly important role in today’s society. They are often found in consumer products (e.g., in automotive systems and cellular phones), and are therefore subject to hard economic constraints. The pervasive nature of these systems generates further constraints on physical size and power consumption. These product-level constraints give ri

SUBLINEAR CONVERGENCE OF A TAMED STOCHASTIC GRADIENT DESCENT METHOD IN HILBERT SPACE

In this paper, we introduce the tamed stochastic gradient descent method (TSGD) for optimization problems. Inspired by the tamed Euler scheme, which is a commonly used method within the context of stochastic differential equations, TSGD is an explicit scheme that exhibits stability properties similar to those of implicit schemes. As its computational cost is essentially equivalent to that of the w

Assessing the structural and dynamical properties of concentrated solutions of the disordered proteins Histatin 5 and its tandem repeat

Intrinsically disordered proteins are distinguished by a lack of distinct three-dimensional structure, existing instead as an ensemble of heterogenous structures. In this research, the effect of crowding on these proteins is investigated using a combined approach of experiment and computer simulation, mainly using coarse-grained simulation models to make simulation computationally feasible at the

A multiscale analysis of multi-agent coverage control algorithms

This paper presents a theoretical framework for the design and analysis of gradient descent-based algorithms for coverage control tasks involving robot swarms. We adopt a multiscale approach to analysis and design to ensure consistency of the algorithms in the large-scale limit. First, we represent the macroscopic configuration of the swarm as a probability measure and formulate the macroscopic co

AMCIS 2018 New Orleans Paper Submission Why Marginalized Groups Struggle to Leverage Digital Activism

Digital activism, political activism mediated by digital technologies, offers the promise of increased visibility and political power for marginalized groups. Yet, this has not been the case outside of a few exceptions such as Black Lives Matter. This paper offers theoretical, conceptual critical research that explores why successful digital activism may elude marginalized groups. We ask why many

Imagining a post-antibiotic era : a cultural analysis of crisis and antibiotic resistance

The study presented in this article is about the role played by imagination when national and international organisations convey the idea of a dystopian crisis involved in the real transition to a postantibiotic era. The present is an era that can be defined as a time when no new antibiotics are discovered or developed, and existing antibiotics simultaneously become less effective since bacteria d

Vertical ground heat exchanger pressure loss – Experimental comparisons and calculation procedures

Vertical ground heat exchangers (GHEs) used with ground source heat pump systems have been constructed in a variety of configurations including single U-tubes, double U-tubes, quadruple U-tubes, and coaxial-type. Selections of vertical GHE other than single U-tubes are often motivated by a desire to decrease the borehole thermal resistance and therefore reduce the required amount of drilling and/o

Borders before Nations : Encounters in the Akan and Dzungar Borderlands, 1450–1750

This article combines the methodological approaches and insights of two scholars working in distinct regions of the early modern world, namely West Africa and Central Asia, to consider border-making outside of Europe before the nation state. Using borders to understand historical developments is not unprecedented and decades of borderland studies have shown how borders result from, and are affecte

Autoimmunity in sarcoidosis : the tip of the Iceberg

Sarcoidosis is a mysterious condition with an etiology that has to date eluded explanation. Innumerable clinical and serological organ- and non-organ-specific autoimmune associations have been reported. Many of the associated conditions are life-threatening but easily manageable if diagnosed early. Due to the long latency that precedes the clinical onset of autoimmune diseases, it is prudent to en

Promoting outdoor recreation among older adults in Sweden : – a theoretical and empirical foundation for the development of an intervention

Background: Disengagement from outdoor recreation may diminish the positive benefits on health and well-beingin old age. The purpose of this study is to present a contextual, theoretical, and empirical rationale for anintervention, aiming to promote continued engagement in outdoor recreation for older adults in a Swedishcontext.Methods: The paper includes a contextualization of outdoor recreation

The Art of Listening in the Gospel of Matthew and Paul’s Letter to the Romans

This revised lecture highlights two aspects of listening in the Bible, that of listening as an obedient act of confession according to the Gospel of Matthew and that of listening to and interpreting the oral performance of Paul’s letter to the Romans. The former aspect is specific to the socio-religious commitment in ancient Israel and Judaism, including the Jewish Christ-believers, and identifiesThis revised lecture highlights two aspects of listening in the Bible, that of listening as an obedient act of confession according to the Gospel of Matthew and that of listening to and interpreting the oral performance of Paul’s letter to the Romans.
