Semiconducting carbon nanotubes (CNTs) are attractive as channel material for field-effect transistors due to their high carrier mobility. In this paper we show that a local CNT gate can provide a significant improvement in the subthreshold slope of a CNT transistor compared to back gate switching and provide gate delays as low as 5 ps. The CNT gated CNT transistor devices are fabricated using a t
The polarization dependence of the split two peaks in the lone-pair region in the x-ray emission spectra has been determined at several different excitation energies for both D 2O and H 2O water. In contrast to predictions based on a narrow range of local water structures where the two peaks would be of different molecular orbital symmetry and arise from, respectively, intact and dissociated molec
This paper addresses the problem of adaptively controlling a plant with unknown parameters using communication-limited feedback. Assuming known dynamics, expressions have recently been obtained for the minimum average feedback data rate required for asymptotic stabilisability. The main purpose of this work is to demonstrate that this minimum rate does not increase if the plant parameters are unkno
Gambella is one of the regional states in Ethiopia where huge tracts of land have been leased out to domestic and international investors since the global food, fuel and financial crisis of 2007/2008. The Gambella region is also one of the most marginalized regions in Ethiopia. It has been alienated from the central politics and socio-economic activities of the state. In the past, the Gambella reg
Discontinuous Galerkin composite finite element methods (DGCFEM) are designed to tackle approximation problems on complicated domains. Partial differential equations posed on complicated domain are common when there are mesoscopic or local phenomena which need to be modelled at the same time as macroscopic phenomena. In this paper, an optical lattice will be used to illustrate the performance of t
Public sector mergers have the potential of being viable alternative to other public sector reforms in the striving toward making public service provision more equipped to confront some of the challenges faced today. Mergers however often fail to deliver promised results. Previous research point to the importance of post-merger integrating processes for realizing the synergies expected from merger
Building on work of Williams,Wieler proved that every irreducible Smale space with totally disconnected stable sets can be realized via a stationary inverse limit. Using this result, the first and fourth listed authors of the present paper showed that the stable C∗-algebra associated to such a Smale space can be obtained from a stationary inductive limit of a Fell algebra. Its spectrum is typicall
Preparing travel time data can be a time-consuming process, which greatly limits the flexibility of transport simulation models. In the current paper, we present an approach to integrate a routing engine locally in an existing modeling framework, hence enabling to dynamically calculate travel times in the constructed emergency medical services (EMS) simulation models. This integration eliminates t
Understanding how momentum anisotropies arise in small collision systems is important for a quantitative understanding of collectivity in terms of QCD dynamics in small and large collision systems. In this letter we present results for small collision systems from the newly developed parton cascade ALPACA, which faithfully encodes the AMY effective kinetic theory. ALPACA reproduces quantitatively
This study uses an experimental scale-up model together with a high-speed camera setup to quantitatively study the effect of Weber number on the breakup probability, deformation time, breakup time, breakup position, and breakup rate in this geometry in a turbulent jet. Results show an increase in breakup probability and a decrease in deformation and breakup times with increasing Weber number. Brea
Waterborne diseases lead to over 6 billion diarrheal episodes per year, with most of the burden on children in low-income countries. We employ hydrological engineering principles to construct a novel measure of stagnant water, crucial to the spread of these diseases. Using a difference-in-differences approach, we estimate the causal effect of stagnant water on the health and cognitive skills of Ta
Libraries of things (LoTs) have potential to create positive environmental and social impact. However, not enough is known about their social impact, especially as LoTs scale. This thesis studies the case of Circle Centre (CC), a LoT in Lund, Sweden and analyzes the social impact of LoTs through interviews and a survey. After understanding the social impact, participants in a participatory qualita

Spin relaxation theory and nuclear magnetic resonance spectroscopy in amphiphilic liquid crystals are presented. Group theory is used to determine the information content and the orientation dependence in spin relaxation experiments, and to investigate the combined effect of crystal and local symmetries and the effect of symmetry on multiple timescales. From lineshapes of a deuterated decanol and
We consider a stochastic version of the proximal point algorithm for convex optimization problems posed on a Hilbert space. A typical application of this is supervised learning. While the method is not new, it has not been extensively analyzed in this form. Indeed, most related results are confined to the finite-dimensional setting, where error bounds could depend on the dimension of the space. On
