Tracing processes in auxiliarization : Time-sufficiency verbs from a Norwegian-Swedish-English contrastive perspective

This chapter considers the Norwegian verb rekke ('reach') and its English correspondences in a bi-directional translation corpus (ENPC), as well as occurrences of rekke in Norwegian monolingual corpora. We suggest that rekke is undergoing grammaticalization from a concrete lexical spatial verb towards a (semi-)auxiliary that contains a component of time sufficiency, similar to Swedish hinna (Johan

Echo time dependence of biexponential and triexponential intravoxel incoherent motion parameters in the liver

Purpose: Intravoxel incoherent motion (IVIM) studies are performed with different acquisition protocols. Comparing them requires knowledge of echo time (TE) dependencies. The TE-dependence of the biexponential perfusion fraction f is well-documented, unlike that of its triexponential counterparts f1 and f2 and the biexponential and triexponential pseudodiffusion coefficients D*, (Formula presented

Utveckling på en ändlig planet : Ett dilemma i svensk biståndshistoria

Under 1960- och 1970-talen etablerades internationellt bistånds- och utvecklingsarbete som en ny och betydelsefull del av svensk utrikespolitik.1 Sedan dess har Sverige förblivit en i internationell jämförelse betydande biståndsgivare, i synnerhet med hänsyn tagen till folkmängd och BNP.2 Genom utvecklingsbiståndet etablerade Sverige bilaterala relationer med länder i andra världsdelar och intog e

Femtosecond laser-induced quantum-beat superfluorescence of atomic oxygen in a flame

Among different approaches to generate mirrorless lasing, resonant multiphoton pumping of gas constituents by deep-UV laser pulses exhibits so far the highest efficiency and produces measurable lasing energies, but the underlying mechanism was not yet fully settled. Here, we report lasing generation from atomic oxygen in a methane-air flame via femtosecond two-photon excitation. Temporal profiles

Visual acuity of budgerigars for moving targets

For a bird, it is often vital to visually detect food items, predators, or individuals from the same flock, i.e. moving stimuli of various shapes. Yet, behavioural tests of visual spatial acuity traditionally use stationary gratings as stimuli. We have behaviourally tested the ability of budgerigars (Melopsittacus undulatus) to detect a black circular target, moving semi-randomly at 1.69 degrees s

The last decades have seen a noticeable increase in cognitive science studies that have changed the understanding of human thinking. Its relevance for historical research cannot be overlooked any more. Cognitive history could be explained as the study of how humans in history used their cognitive abilities in order to understand the world around them and to orient themselves in it, but also how th

Development of New Approaches to ATLAS Detector Simulation and Dark Matter Searches with Trigger Level Analysis

Elementary particles and their interactions are successfully described by the Standard Model of particle physics (SM). However, it has been observed that extensions Beyond the Standard Model (BSM) are required to account for a large part of yet undiscovered particles and interactions, such as Dark Matter (DM).To advance the knowledge of the SM and to pursue DM discoveries, CERN has the ambitious p

Nano-Infrared Imaging of Primary Neurons

Alzheimer’s disease (AD) accounts for about 70% of neurodegenerative diseases and is a cause of cognitive decline and death for one-third of seniors. AD is currently underdiagnosed, and it cannot be effectively prevented. Aggregation of amyloid-β (Aβ) proteins has been linked to the development of AD, and it has been established that, under pathological conditions, Aβ proteins undergo structural c

Vibrotactile sense in children with type 1 diabetes

Poster A153Introduction: Diabetic peripheral neuropathy (DPN) is a devastating complication to DM, potentially leading to diabetic foot ulcers. Studies using electrophysiology shows high occurrence of subclinical DPN among children, but it is unclear when and how to start screen children with T1D for DPN. Aim: To investigate whether evaluation of the vibrotactile sense, using a multi-frequency method, in the

Immersion freezing ability of freshly emitted soot with various physico-chemical characteristics

The immersion freezing ability of soot particles has in previous studies been reported in the range of low/insignificant to very high. The aims of this study were to: (i) perform detailed physico-chemical characterisation of freshly produced soot particles with very different properties, (ii) investigate the immersion freezing ability of the same particles, and (iii) investigate the potential link

Molecular dynamics simulations of phosphorylated intrinsically disordered proteins : A force field comparison

Phosphorylation is a common post-translational modification among intrinsically disordered proteins and regions, which helps regulate function by changing the protein conformations, dynamics, and interactions with binding partners. To fully comprehend the effects of phospho-rylation, computer simulations are a helpful tool, although they are dependent on the accuracy of the force field used. Here,

Probing the spin correlations of tt¯ production at NLO QCD+EW

In this work we investigate the NLO QCD+EW corrections to the top quark pair production and their effects on the spin correlation coefficients and asymmetries at fixed-order top quark pair production and LO decay in the dilepton channel, within the narrow-width approximation. The spin correlations are implicitly measured through the lepton kinematics. Moreover we study the EW effects to the lepton

Dissipation Reduction and Information-to-Measurement Conversion in DNA Pulling Experiments with Feedback Protocols

Information-to-energy conversion with feedback measurement stands as one of the most intriguing aspects of the thermodynamics of information in the nanoscale. To date, experiments have focused on feedback protocols for work extraction. Here we address the novel case of dissipation reduction in nonequilibrium systems with feedback. We perform pulling experiments on DNA hairpins with optical tweezer

Into the storm : Diving into the winds of the ultra-hot Jupiter WASP-76 b with HARPS and ESPRESSO

Context. Despite swift progress in the characterisation of exoplanet atmospheres in composition and structure, the study of atmospheric dynamics has not progressed at the same speed. While theoretical models have been developed to describe the lower layers of the atmosphere, and independently, the exosphere, little is known about the intermediate layers up to the thermosphere. Aims. We aim to prov
