X-ray parametric amplification is a high order parametric process with the capability to amplify ultrashort laser pulses with broad spectrum ranging from the extreme ultraviolet to the soft x-ray. In this contribution, the dynamics of this broadband amplification schema is studied with sub-20-as temporal resolution by seeding the amplifier with a train of 200-as-long pulses at 11 nm central wavele

Local agency is marked by its structural boundedness including nation state strategies. We investigate the dynamic and mutually constitutive interrelationship between agency and state strategies to better understand and explain change in local development with the examples of four mining towns: Kiruna (Sweden), Zeitz (Germany), Most (Czechia) and Tatabánya (Hungary). They embody processes of indus

The paper follows the development of the tourism industry in a small, traditional mining town in northern Sweden. It highlights local agency in the diversification process, as well as interpath relations between tourism and mining. Drawing on 21 semi-structured interviews, the paper finds that the two seemingly unrelated paths share the need for a variety of local endowments and in so the dominant

Hot carrier effects have been observed in recent measurements of III–Nitride (III–N) light-emitting diodes. In this paper we carry out bipolar Monte Carlo simulations for electrons and holes in a typical III–N multi-quantum well (MQW) LED. According to our simulations, significant non-quasiequilibrium carrier distributions exist in the barrier layers of the structure. This is observed as average c

Agricultural intensification and extreme weather events can represent considerable stress to soil microorganisms and their functions by influencing the key players behind the degradation of soil organic matter. A better understanding of the diversity and abundance of microbial functional genes that predict the functional potential of soils, can link the microbial communities to their key ecosystem

So far, the semiconductor nanowire research area has mainly delivered results on growth procedures and related material properties. As the development lately has been successful in producing novel nanowire-based structures for optical or electronic applications, the time is ripe to review the device work that has been done and in some cases has produced devices ready for the market. In this chapte

Enzymes have come into use for many new applications outside their natural biological environment, taking advantage of their high efficiency and selectivity as biocatalysts. Such new application often requires encapsulation to preserve the structure and activity of the enzyme, but also to regulate and control the activity. Here, we will discuss two types of encapsulation, soft matrices consisting

This paper reports on Large Eddy Simulation (LES) of turbulent premixed methane/air flames approaching blow-off. The study focuses on a stable flame, and on a flame just prior to blow-off, both stabilized by the Cambridge bluff-body burner. For turbulence-chemistry interaction, a model based on transported probability density function (TPDF) in conjunction with Eulerian stochastic fields is used.

We investigate a particular subclass of semantic features associated with demonstratives of quantity and quality, and the respective interrogatives. We explore these lexical elements as they behave linguistically in simile constructions in Croatian. We show that the semantic features that can be focused on in similes are the same as the references of the full system of Croatian demonstratives. How

We incorporate age-specific socio-economic interactions in a SIR macroeconomic model to study the role of demographic factors for the COVID-19 epidemic evolution, its macroeconomic outcomes and possible containment measures. Our framework captures the endogenous response of rational individuals who freely reduce consumption- and labor-related personal exposure to the virus, with interactions that

This paper aims to synthesize previous user innovation policy proposals into an adapted systems of innovation framework, on which a future holistic user innovation policy for the household sector can be based. We do this in three steps. First, we introduce the systems of innovation framework as a comprehensive basis for a holistic approach to innovation policy. Second, we identify and review polic

Middle Eastern immigrants are at high-risk for insulin resistance. Fatty acid composition (FAC) plays an important role in the development of insulin resistance but has not been investigated in people of Middle Eastern ancestry. Here, the aim was to assess the FAC in visceral and subcutaneous adipose tissue (VAT and SAT) in healthy Iraqi- and Swedish-born men using a magnetic resonance imaging (MR

Även om de politiska kriserna i Belarus och Kazakstan redan är under åtminstone tillfällig kontroll är de liksom ökande politiska spänningar i Ryssland avgörande för att förstå Putins paranoia. Det skriver Tomas Sniegon, historiker och docent i Europastudier vid Lunds universitet.

PURPOSE: Fibromyalgia (FM) is a complex pain condition, and exercise is considered the first option of treatment. Few studies have examined the effect of exercise on molecular mechanisms in FM. The aim of this study was to analyze the plasma proteome in women with FM and healthy controls (CON) before and after 15 wk of resistance exercise. This study further investigated whether clinical and exerc

We conduct the first 3D hydrodynamic simulations of oxygen-neon white dwarf-neutron star/black hole mergers (ONe WD-NS/BH mergers). Such mergers constitute a significant fraction, and may even dominate, the inspiral rates of all WD-NS binaries. We post-process our simulations to obtain the nuclear evolution of these systems and couple the results to a supernova spectral synthesis code to obtain th
