Beam-driven plasma-wakefield acceleration is an acceleration scheme promising accelerating fields of at least two to three orders of magnitude higher than in conventional radiofrequency accelerating structures. The scheme relies on using a charged particle bunch (driver) to drive a non-linear plasma wake, into which a second bunch (witness) can be injected at an appropriate distance behind the fir

Knowing the longitudinal phase space of an electron beam is one of the most important and crucial issues in short-pulses linacs. To achieve this task expensive and rather complicated setups (like transverse deflecting cavities) are usually implemented. The MAX IV linac is a 3GeV accelerator which will be used to inject into two rings and to drive a short pulse facility. Nevertheless, a more deep u

Inflammasomes are cytosolic multiprotein complexes that assemble in response to infectious or noxious stimuli and activate the CASPASE-1 protease. The inflammasome containing the nucleotide binding domain-leucine-rich repeat (NBD-LRR) protein NLRC4 (interleukin-converting enzyme protease-activating factor [IPAF]) responds to the cytosolic presence of bacterial proteins such as flagellin or the inn

In this paper, we present a study of Swedish inhabitants' preferences for distribution in three dimensions in the context of transport investments. Using choice experiments, we study the respondents' preferences for the distribution of benefits in the geographical, gender, and income dimension in relation to aggregate benefits. We find that they have quite strong preferences for equality in all di

This paper develops a conceptual framework for understanding how organizations create an accepted purpose for organizational change initiatives related to business processes. The framework is based on a longitudinal study related to an Action Research project and the ‘higher level learning’ from using a performance measurement system for change initiatives. Over more than four years, we followed a

We study experimentally work fluctuations in a Szilard engine that extracts work from information encoded as the occupancy of an electron level in a semiconductor quantum dot. We show that as the average work extracted per bit of information increases toward the Landauer limit Formula Presented, the work fluctuations decrease in accordance with the work fluctuation-dissipation relation. We compare

Research on the efficacy of hypnosis applications continues to grow, but there remain major gaps between the science and clinical practice. One challenge has been a lack of consensus on which applications of hypnosis are efficacious based on research evidence. In 2018, 6 major hypnosis organizations collaborated to form the Task Force for Establishing Efficacy Standards for Clinical Hypnosis. This

The paper suggests a method for compensating the impact of friction for the control nonlinear systems, where the original controller (derived without taking into account friction) results from the passivity relation. The illustrative example is given.

We discuss the Layzer quenched ground state configuration of [Kr]4d104f13 along the Praseodymium (Pr) isoelectronic sequence between 80≤Z≤100. The 2F fine structure energy is examined from the point of view of the various contirbutions: correlation, frequency-independent and dependent Breit interaction and the two QED terms, self energy and vacuum polarisation. We find the fine structure energy to

Contact allergy induced by certain chemicals is a common health concern, and several alternative methods have been developed to fulfill the requirements of European legislation with regard to hazard assessment of potential skin sensitizers. However, validated methods, which provide information about the potency of skin sensitizers, are still lacking. The cell-based assay Genomic Allergen Rapid Det

A method was developed, which drives the selection of appropriate solar control mechanisms based on theanalysis of overheating due to solar heat gains. The aim of the method is to maintain adequate thermalcomfort levels in highly glazed spaces. Two thermal comfort models, Predicted Mean Vote and AdaptiveModel, were chosen to set the thermal comfort boundaries included in the method. Moreover, in o

Prevention is viewed as a key issue for general practice, yet there is a lack of evidence regarding general practitioners’ interventions in both middle-aged and elderly people. This is despite the fact that recommendations and key indicators for monitoring the use of clinical preventive strategies aimed at these groups are available and that both the World Health Organization and European Commissi

This chapter introduces the system for crisis management in Sweden. Over the last century, Sweden has gone from being a poor European backwater to being among the countries with the highest human development in the world. The droughts and harsh winters that killed thousands and drove numerous Swedes to emigrate in the past are mere distractions today and the contemporary system for crisis manageme

We analyse the effect of business model innovation (BMI) on the product innovation performance of firms, based on a dynamic capabilities theoretical framework. Our empirical study is based on a large-scale representative sample of cross-industry Swedish firms participating in three waves of the Community Innovation Survey (CIS) from 2008 to 2012. We hypothesise that BMI in the form of product inno
