Spiral spin liquids are an exotic class of correlated paramagnets with an enigmatic magnetic ground state composed of a degenerate manifold of fluctuating spin spirals. Experimental realizations of the spiral spin liquid are scarce, mainly due to the prominence of structural distortions in candidate materials that can trigger order-by-disorder transitions to more conventionally ordered magnetic gr
Combined quantum mechanics and molecular mechanics (QM/MM) calculations are a popular approach to study reaction mechanisms of enzymes. However, recently, the reproducibility of such calculations has been questioned, comparing the results of two software: NWChem and Q-Chem. Here, we continue and extend this study by including three additional software─ComQum, ORCA, and AMBER─using the same test ca
Despite the advancement in background rejection techniques, observation of the very-high-energy gamma-ray sky by imaging atmospheric Cherenkov telescopes (IACTs) are subject to an irreducible background from gamma-like hadron- or electron-induced air showers. The determination of this residual background is crucial for accurate spectral and spatial measurements. The Cherenkov Telescope Array (CTA)
The clinical commissioning of beams for neutron capture therapy involves the measurement and analysis of a large amount of data in various geometries and using various detectors. We have attempted methods and considerations common to the radiotherapy field, while particular care and attention is given to the specifics of the field of neutron capture therapy. This chapter provides an introduction a
BACKGROUND: The tau-PET radiotracer [18F]flortaucipir enables in vivo detection of tau pathology in Alzheimer's Disease (AD) and has recently been FDA- and EMA-approved for clinical use. To support its implementation, we assessed tau-PET's positive predictive value (PPV) and negative predictive value (NPV) for clinico-pathological AD while accounting for age, amyloid-status, and pre-PET diagnostic
The T-REX neutron spectrometer at the European Spallation Source will use Multi-Grid Technology, which is a voxelised proportional counter relying on 10B4C coatings to detect neutrons scattered by the sample under investigation. Measurements of the position dependence of pulse-height and relative detection efficiency of a Multi-Grid prototype of the T-REX spectrometer are presented for two differe
Essentially all academic research of today relies on analysis of data from a wide range of sources. Several underpinning, and rapidly developing, technologies are supporting the analysis of this data. Visualization serves as an interface to this ecosystem of tools and methods and integrates them into environments supporting scientific workflows, effectively sharing cognitive load between computers
Shared ground heat exchange can deliver low-carbon electrified heat where individual heat pumps or heat networks are not feasible, such as in terraced homes. However, there is a policy gap around these mid-scale heat solutions. We outline the benefits and challenges of shared ground heat exchange, and actions needed by policy, housing, and innovation stakeholders to support further deployment.
The amyloid precursor protein intracellular domain (AICD) is an intrinsically disordered regulatory segment whose conserved YENPTY motif mediates transient interactions with multiple adaptor and signaling proteins. How sequence perturbations within this motif modulate its accessibility and interaction potential within a disordered ensemble remains poorly understood. Here, we combine small-angle X-
Research seminar on early life factors influencing adult health and disease Time: Wednesday 22nd January 2020, 13:30 to 16:45 p.m. Venue: Lecture Hall “Medelhavet”, Wallenberg Lab, Jan Waldenströms gata, SUS, Malmö (in front of the CRC building, 10 min walk from the “Triangeln” railway station) Audience: Researchers and students interested in the Developmental Origins of Adult Health and Disease (
The increase in the scale of LHC computing during Run 3 and Run 4 (HL-LHC) will certainly require radical changes to the computing models and the data processing of the LHC experiments. The working group established by WLCG and the HEP Software Foundation to investigate all aspects of the cost of computing and how to optimise them has continued producing results and improving our understanding of
While pure deliberation has still not been found online, the field of online deliberation research is blossoming. Born out of the “frustrations and possibilities” of the 1990s, a current theme in the field is to re-link deliberative theory with empirical political science. The aim of this systematic literature review is to sort out and examine important features of this development; to identify an
Ultrasound optical tomography is a medical imaging modality that combines ultrasound and light to improve the low resolution of optical imaging caused by scattering in tissue. Photons passing through an ultrasound pulse have a probability of being frequency shifted. By filtering out these photons and analysing them, images with optical contrast and ultrasound resolution can be obtained. In this t
This thesis considers solitary standing wave solutions to the Davey-Stewart-son equation, which is a model for surface waves on a body of water in three dimensions. In a special case, the Davey-Stewartson equation is reduced to the well-known non-linear Schrödinger equation with cubic power which is known to have a countable familiy of radial standing waves. One of the aims of this thesis is to in
Purpose – The purpose of this study is to uncover what motivational factors exists for companies to use co-creational methods. It also aims to recognize what beneficial factors can come from using these methods. The restriction of using social media depending on industry or size of company will be reflected upon. The main research question is “What motivates companies to use customer co-creation a
Safety, privacy and comfort are elements that need to be improved on Swedish shelters. Since several homeless individuals often share bedrooms, it is not uncommon for them to be exposed to violence, harassment and theft or a generally disturbing environment during their stay. These are all contributing factors to an increased difficulty in getting out of homelessness. Enfold is a flexible w
