Paramagnon dispersion and damping in doped NaxCa2-xCuO2Cl2
Using resonant inelastic x-ray scattering, we measure the paramagnon dispersion and damping of undoped, antiferromagnetic Formula Presented as well as doped, superconducting Formula Presented. Our estimation of the spin-exchange parameter and width of the paramagnon peak at the zone boundary Formula Presented confirms that no simple relation can be drawn between these parameters and the critical t
Predicting Perceptual Centers Located at Vowel Onset in German Speech Using Long Short-Term Memory Networks
Perceptual centers (p-centers) can be defined as the perceived centers of a syllable. Previous research regarding the location of p-centers in speech relied on experimental methods, and among the suggested acoustic features contributing to the location of p-centers in Germanic languages is the transition of the consonant to the vowel onset. The current study investigates the prediction of the loca
Soft QCD theory
Soft QCD is beyond perturbative control, and therefore phenomenological models have to be developed. These are implemented and combined within event generators. Typical aspects considered are multiparton interactions, colour reconnection, and hadronization. Of special interest are non-universal features of hadronization at the LHC, such as the recently observed enhancement of charm and bottom bary
Effects of socioeconomic status on patient-reported outcome after surgically treated trigger finger : a retrospective national registry-based study
OBJECTIVES: To investigate if socioeconomic status impacts patient-reported outcomes after a surgically treated trigger finger (TF).DESIGN AND SETTING: Data on patients with TF treated with surgery were collected from the Swedish National Quality Registry of Hand Surgery (HAKIR) 2010-2019 with an evaluation of symptoms and disability before surgery and at 3 and 12 months after surgery, using the s
Overcoming extended lag phase on optically pure lactic acid production from pretreated softwood solids
Optically pure lactic acid (LA) is needed in PLA (poly-lactic acid) production to build a crystalline structure with a higher melting point of the biopolymer than that of the racemic mixture. Lignocellulosic biomass can be used as raw material for LA production, in a non-food biorefinery concept. In the present study, genetically engineered P. acidilactici ZP26 was cultivated in a simultaneous sac

The slavery history of historical predecessors of ABN AMRO : An investigation into Hope & Co. and R. Mees & Zoonen
This report looks at the involvement of two of ABN AMRO's predecessors - Hope & Co. and R. Mees & Zoonen - in slavery and the slave trade during the eighteenth and nineteenth century, both in the Atlantic world and in Asia. It finds that Hope & Co. played a pivotal role in the international slave economy of the 18th century. Not only were slavery-related operations a source of much of

Local effects of printed logos and reflective stripinfixed to firefighter clothing material packages under low radiation exposure
Notifications that related 1st degree burns to reflective striping and impermeable clothing elements did reach the investigators, while the mechanisms behind this phenomenon are still unclear. Material tests for thermal and evaporative resistance, and for heat transmission under dry and wet conditions at low radiation levels were done to evaluate the performance of protective clothing with and wit
Bettan – Industrial robot and application for Finja Exakt build system
This paper reports on efforts to create a robotized construction build system, based on the Finja Exakt manual build system. The equipment used is a generic off-the-shelf industrial arm robot integrated with a spindle crane carrier for mobility. The approach offers technical, safety and usability challenges as well as integration and business challenges for placing a generic industrial robot onsit
Experiences of participating in a group-based sensory modulation intervention for mental health service users
BACKGROUND: People with mental health issues often experience difficulties with sensory modulation affecting occupational engagement. Research conducted in inpatient units has shown positive effects of individual sensory modulation interventions, however, research on experiences of group-based interventions in outpatient units is limited. Hence, a group-based sensory modulation intervention was ad
Tunable X-ray dark-field imaging for sub-resolution feature size quantification in porous media
X-ray computed micro-tomography typically involves a trade-off between sample size and resolution, complicating the study at a micrometer scale of representative volumes of materials with broad feature size distributions (e.g. natural stones). X-ray dark-field tomography exploits scattering to probe sub-resolution features, promising to overcome this trade-off. In this work, we present a quantific
Simultaneous Reciprocal and Real Space X-Ray Imaging of Time-Evolving Systems
Imaging the (sub)micron scale over large areas with high temporal resolution becomes increasingly necessary for the development and investigation of novel materials under realistic operation conditions. Small angle x-ray scattering imaging methods provide micro- and nanoscale structural information of materials. A fundamental shortcoming of such methods is the long acquisition time required to inv
Metal assisted chemical etching of silicon in the gas phase : A nanofabrication platform for X-ray optics
High aspect ratio nanostructuring requires high precision pattern transfer with highly directional etching. In this work, we demonstrate the fabrication of structures with ultra-high aspect ratios (up to 10 000 : 1) in the nanoscale regime (down to 10 nm) by platinum assisted chemical etching of silicon in the gas phase. The etching gas is created by a vapour of water diluted hydrofluoric acid and
Operando Visualization of Water Distribution in Gas Diffusion Media of PEFCs with an Optimized Neutron Grating Interferometer
We demonstrated the use of a neutron grating interferometer setup (nGI) with a significantly improved contrast-to-noise ratio of the operando dark-field (DF) contrast visualization of water in gas diffusion media (GDM). The nGI parameters were optimized in such a way that we could perform DF imaging of a fully operational fuel cell including two GDM layers (anode and cathode side). The DF contrast
X-ray scattering tensor tomography with circular gratings
Three dimensional (3D) information of the microstructure organization of various relevant materials in industry and nature is fundamental to master the understanding of their macroscopic properties. X-ray scattering tensor tomography provides 3D directional information on unresolved microstructures in large volumes, facilitating the investigation of the microstructural organization in statisticall
