Design of Switched Antenna Arrays for a 28 GHz Propagation Channel Sounder

A channel sounder is an advanced measurement system to estimate the behavior of wireless propagation channels. In this paper, we present the antenna array design for a 28GHz massive multiple-input multiple-output system, capable of measuring 256×128 dual-polarized channels, including dynamic properties of angular, delay, Doppler, and polarization parameters, respectively. Unique in comparison to o

pH dependence of aqueous oxalic acid observed by X-ray absorption and emission spectroscopy

In this work, X-ray absorption spectroscopy (XAS) and site-selective X-ray emission spectroscopy (XES) were used to measure the oxygen K-edge (OC=O,1s and OCO − ,1s) of oxalic acid, with theoretical calculations performed to reproduce the spectra observed. Structure sampling of a cluster model was performed using an ab initio molecular dynamics trajectory. Relative XES intensities from core-hole e

Incorporation of Multinuclear Copper Active Sites into Nitrogen-Doped Graphene for Electrochemical Oxygen Reduction

Multinuclear metal active sites are widely used as catalytic reaction centers in metalloenzymes and generally show high catalytic activity. For example, laccases are known to catalyze the oxygen reduction reaction (ORR) to water at a multinuclear copper site with almost no energy loss. The ORR is an important reaction not only in oxygenic respiration but also in future energy generation devices su

Non-ambulatory children with cerebral palsy : effects of four months of static and dynamic standing exercise on passive range of motion and spasticity in the hip

Purpose: The aim of this study was to compare the effects of four months of two types of structured training regimes, static standing (StS) versus dynamic standing (DyS), on passive range of motion (PROM) and spasticity in the hip among non-ambulatory children with cerebral palsy.Method: Twenty non-ambulatory children with cerebral palsy participated in an exercise intervention study with a crosso

Märta Strömberg (1921–2012)

Biographical essay on Märta Strömberg, professor of Archaeology in Lund. She was one of the first female archaeologists that took place in the university world. She became a committed mentor for generations of students, doctoral students and colleagues. Her archaeological investigations of the Stone Age megalithic tombs, the Bronze Age and the Iron Age grave fields and settlements became methodolo

Governing the Climate-Energy Nexus : Challenges to Coherence, Legitimacy and Effectiveness

Combating climate change and transitioning to fossil-free energy are two central and interdependent challenges facing humanity today. Governing the nexus of these challenges is complex, and includes multiple intergovernmental and transnational institutions. This book analyses the governance interactions between such institutions, and explores their consequences for legitimacy and effectiveness. Us

Introduction: The Governance of the Climate-Energy Nexus

The introduction first explains the rationale and theoretical and empirical contributions of the edited volume. The book seeks to address a considerable gap of knowledge of the nature of the relationship between institutions governing the climate-energy nexus in a multilevel context. In particular, there is scant research on consequences on the legitimacy and effectiveness of governance arrangemen

Conclusions: Coherence, Management, Legitimacy and Effectiveness in the Climate-Energy Nexus

The concluding chapter first summarizes some of the volume’s main results along the four evaluative themes. In terms of coherence and management, the three policy fields under scrutiny – renewable energy, fossil fuel subsidy reform and carbon pricing – are roughly marked by coordination, rather than competition or outright harmony. Regarding legitimacy, the specializations and work backgrounds of

Analytical Framework: Assessing Coherence, Management, Legitimacy and Effectiveness in an Institutional Nexus

This chapter establishes four evaluative themes that will be employed across this volume to analyze the institutional complexity of policy fields in the climate-energy nexus: coherence, management, legitimacy, and effectiveness. Coherence among institutions is conceptualized along four dimensions: convergence on an overarching core norm for the policy field, balanced coverage and distribution of m

Related variety, recombinant knowledge and regional innovation. Evidence for Sweden, 1991-2010

This study investigates how related variety in the regional employment mix affects the innovation output of a region. Departing from the idea of recombinant innovation, previous research has arguedthat related variety enhances regional innovation as inter-industry knowledge spillovers occur more easily between different but cognitively similar industries. This study combines a novel dataset and re

Socio-ecological factors determine crop performance in agricultural systems

Agricultural production systems are affected by complex interactions between social and ecological factors, which are often hard to integrate in a common analytical framework. We evaluated differences in crop production among farms by integrating components of several related research disciplines in a single socio-ecological analysis. Specifically, we evaluated spring barley (Hordeum vulgare, L.)

Cathepsin g Degrades Both Glycosylated and Unglycosylated Regions of Lubricin, a Synovial Mucin

Lubricin (PRG4) is a mucin type protein that plays an important role in maintaining normal joint function by providing lubrication and chondroprotection. Improper lubricin modification and degradation has been observed in idiopathic osteoarthritis (OA), while the detailed mechanism still remains unknown. We hypothesized that the protease cathepsin G (CG) may participate in degrading lubricin in sy

What if everyone becomes a sharer? A quantification of the environmental impact of access-based consumption for household laundry activities

In order to meet the EU's climate and resource efficiency targets, changes in our daily-life behaviours, as well as business models, are urgently necessary. More insights are needed to make real changes based on research with a systems perspective. We developed a system dynamics model to analyse the environmental benefits of a transition from ownership-based to access-based household laundry activ

Longitudinal degeneration of the basal forebrain predicts subsequent dementia in Parkinson's disease

Objectives: Cholinergic dysfunction plays a prominent role in cognitive impairment in Parkinson's disease (PD). The aim of this study was to assess the relationship of baseline and longitudinal basal forebrain atrophy with cognitive decline and dementia in PD. Methods: We included 106 non-demented PD patients, 19 PD dementia (PDD) patients and 42 controls with longitudinal structural MRI and cogni

Rethinking the chronology of early Paleogene sediments in the western North Atlantic using diatom biostratigraphy

Ocean Drilling Program (ODP) Site 1051 (Blake Nose, western North Atlantic) is of crucial importance for reconstructing diatom evolution and biosiliceous sedimentation patterns through the early Cenozoic period of extreme greenhouse warmth followed by the progressive global cooling. The magnetostratigraphy in Hole 1051A, however, has been subject to divergent interpretations resulting in multi-mil

On the effects of increased coolant temperatures of light duty engines on waste heat recovery

In this paper, an investigation is done into the potential of increasing the coolant temperature of an engine to maximize the powertrain efficiency. The study takes a holistic approach by trying to optimise the combined engine and waste heat recovery system. The work was done experimentally on a Volvo 4-cylinder light duty diesel engine in combination with Rankine cycle simulations. For the study,

Optimization of fin configurations and layouts in a printed circuit heat exchanger for supercritical liquefied natural gas near the pseudo-critical temperature

In this study, the effects of fin configurations and layouts on thermal and hydraulic performances of printed circuit heat exchangers (PCHEs) with supercritical liquefied natural gas as the working fluid are studied by a numerical method, and the overall heat transfer performance of various parameters is evaluated by the JF factor. Firstly, the effect of four different airfoil configurations, i.e.
