The longitudinal movement of the arterial wall of large human arteries has shown promise to be an independent indicator of vascular health. Despite growing interest in this movement, its nature, causes, and implications are not fully understood, and existing phantoms have failed to show a pure longitudinal movement that is not secondary to the distension. An often overlooked aspect of the arterial

Organic-shell-free PbS nanoparticles have been produced in the size range relevant for quantum-dot solar cells (QDSCs) by a vapor aggregation method involving magnetron reactive sputtering. This method creates a beam of free 5-10 nm particles in a vacuum. The dimensions of the particles were estimated after their deposition on a substrate by imaging them using ex situ SEM and HRTEM electron micros

Manganese(IV)-oxo complexes are often invoked as intermediates in Mn-catalyzed C-H bond activation reactions. While many synthetic MnIV-oxo species are mild oxidants, other members of this class can attack strong C-H bonds. The basis for these reactivity differences is not well understood. Here we describe a series of MnIV-oxo complexes with N5 pentadentate ligands that modulate the equatorial lig

Objectives: Ambulance services and stroke alerts reduce the time from stroke onset to acute stroke diagnosis. We describe the use of stroke alerts and ambulance services in different hospitals and patient groups and their relationship with reperfusion therapy. Methods: This nationwide study included 49,907 patients admitted with acute stroke who were registered in The Swedish Stroke Register (Riks

Self-consistent dynamics of non-homogeneous fluctuations and homogeneous and isotropic condensate of Yang–Mills fields was investigated in zero, linear and quasilinear approximations over the wave modes in the framework of N = 4 supersymmetric model in Hamilton gauge in quasiclassical theory. The models with SU(2), SU(3) and SU(4) gauge groups were considered. Particle production effect and effect

The Baltic Sea environment has since the early 1970s passed through several phases of spatial objectification in which the ostensibly well-defined semi-enclosed sea has been framed and reframed as a geographical object for intergovernmental environmental politics. Based on a historical analysis of this development, this article suggests that environmental politics critically depend on the delineat

Using the development of intergovernmental environmental cooperation in the Baltic Sea area as a concrete example, the aim of this study is to explore how the ‘environ- ment’ in situations of environmental interdependence is identified and institutional- ised as political-geographical objects. ‘Environmental interdependence’ is to this end conceptualised as a tension between ‘political spaces’ of

Background: A key innovation may allow one group of species to radiate and replace another, but the role of competition and background extinctions for the replacement process is vigorously debated and unclear. Questions: Is a minimum competitive advantage necessary to initiate replacement? Are background extinctions of the incumbent species necessary? What speciation and extinction dynamics charac

Powder structure and functionality are expected to be closely linked to the composition and drying process. In order to understand the optimization of the quality of a powder, e.g. encapsulation efficiency, or wetting and dispersion properties, monitoring of the particle microstructure is an attractive concept. However, to study the impact of different parameters in formulation and drying process

A novel Stacked Multi-Level (SML) modulator topology optimized for long pulse and high average power applications has been developed at ESS. It utilizes six identical modules connected in series at the HV output side and fed in parallel from the low voltage side. Each one is formed by one HF inverter, one step-up transformer, one HV rectifier bridge and one HV passive filter. They are supplied, in

The workshop brings together differing perspectives on what makes research data possible. How data is made represents an on-going negotiation between a number of elements. It reflects, firstly, the nature of disciplines and thecomplex way this is linked to cultures of research data and data sharing. Secondly, data is made across the complex temporalities within different practices of its managemen
