Ultrafast electronic and structural dynamics of matter govern rate and selectivity of chemical reactions, as well as phase transitions and efficient switching in functional materials. Since x-rays determine electronic and structural properties with elemental, chemical, orbital and magnetic selectivity, short pulse x-ray sources have become central enablers of ultrafast science. Despite of these st
This paper presents the use of the T-matrix method for a collection of scatterers for validation purposes of large-scale numerical electromagnetic scattering problems. In order to validate the simulation results for large geometries the T-matrix solution for a collection of spheres and disks can be used. Scattering results using the T-matrix method, FDTD and MoM are compared. The results show that
A windowless silicon (Si) diode (4 mm2) was evaluated as alpha particle detector and spectrometer for field measurements. It was irradiated with alpha particles from a 241Am (2.3 kBq) and a 210Po (9 kBq) source at source-detector distances (SDD) of 0.5, 1.0 and 1.8 cm. The energy resolution in terms of full width at half maximum was 281, 148 and 113 keV for SDD of 0.5, 1.0 and 1.8 cm, respectively
This paper presents an assessment framework for methodologies under development. It is adapted from the evaluation framework for the design of an engineering model developed by Ben Ahmed and colleagues [1]. The assessment framework allows to take into account in a systematic way characteristics (that is, main categories or classes of potential requirements) that are of importance for the assessmen
Multidimensional LC-MS based shotgun proteomics experiments at the peptide level have traditionally been carried out by ion exchange in the first dimension and reversed-phase liquid chromatography in the second. Recently, it has been shown that isoelectric focusing (IEF) is an interesting alternative approach to ion exchange separation of peptides in the first dimension. Here we present an improve
Background: To establish integrated healthcare pathways for patients with neurodevelopmental disorders (ND) such as autism spectrum disorder and attention-deficit hyperactivity disorder is challenging. This study sets out to investigate the main concerns for healthcare professionals when integrating ND care pathways and how they resolve these concerns. Methods: Using classic grounded theory (Glase
INTRODUCTION: Huntington's disease (HD) is an incurable chronic neurodegenerative disorder that typically presents in mid-life with a range of motor, cognitive and affective problems. Patients are currently managed using a combination of drug treatments and non-pharmacological therapies but at present there is no "gold standard" treatment for any aspect of the disease.AREAS COVERED: In this review
Solid oxide electrochemical cells (SOCs) are considered a highly promising technology for providing efficient, sustainable and economic conversion between chemical energy and electrical energy. SOCs can be operated as fuel cells, where electric power is obtained from fossil or non-fossil hydrocarbon fuels depending on the origin or as electrolysis cells, whereby using electrical energy from renewa
Parkinson's disease dementia (PDD) has become an increasing area of research as treatments for the motor features of Parkinson's disease (PD) have improved and the population of patients with PD grows and ages. If predictors could be used to identify a sub-population of patients at risk of developing an early PDD then research into its neuropathological basis and treatment could be more effectivel
We propose a novel approach to the problem of inverse kinematics for possibly redundant planar manipulators. We show that, by considering the joints as point masses in a fictitious gravity field, and by adding proper constraints to take into account the length of the links, the kinematic inversion may be cast as a convex programming problem. Convex constraints in the decision variables (in particu
Parabolic sub-sample interpolation for 2D block-matching motion estimation is computationally efficient. However, it is well known that the parabolic interpolation gives a biased motion estimate for displacements greater than |y.2| samples (y = 0, 1, …). Grid slope sub-sample interpolation is less biased, but it shows large variability for displacements close to y.0. We therefore propose to combin
This chapter explores how universities in Sweden have approached the challenges of inclusive development and social innovation. Whereas the higher education system has been quite successful in providing access to previously excluded groups, the concept of social innovation applied to solving social problems has not yet been integrated into the policies and practices of the university innovation sy
Telecommunication monitoring data requires the automation of data analysis workflows. A data mining tool provides data workflow management systems to process and perform analysis tasks. This paper presents an evaluation of two example data mining tools following the principles of design of experiment (DOE) to run forecasting and clustering workflows for telecom monitoring data. We conduct both qua
Technetium is a synthetic element with no stable isotopes, produced as waste in nuclear power plants and in cyclotrons used for nuclear medicine. The element has high mobility, in the form of TcO4 −; its determination is therefore important for environmental protection. Technetium is found in low concentrations and therefore common methods for its analysis include long treatments in several steps
Purpose: Most knowledge regarding outcome after adrenal surgery stems from retrospective studies reported by highly specialized centres. The aim of this study was to report a national experience of adrenalectomy with particular attention to predictive factors for postoperative complications, conversion from endoscopic to open surgery and length of hospital stay. Methods: Adrenalectomies reported i
This study aims to assess the potential of trees for integration in urban development by evaluating the damage caused by trees in relation to various tree characteristics. Tree damage to permeable pavement systems and other urban structures such as impermeable pavements, kerbs, roads, retaining walls, footpaths, walls and buildings were assessed to identify the most suitable trees for the urban en
We aim to introduce some new solutions in the studies involving the subjects who are not able to use spoken language, both animals and pre-verbal infants. Although our research focuses in general on the episodic memory introduced by Tulving in 1972, this paper is to present the case of 12-month-old infants.
