Strong-field nano-optics

The present status and development of strong-field nano-optics, an emerging field of nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is reached when the amplitude of the external electromagnetic fields that are driving a material approach or exceed the field strengths that bind the electrons inside the medium. In this strong-field regime, light-matter interact

An optimized tiling pattern for multiobject spectroscopic surveys : Application to the 4MOST survey

Large multiobject spectroscopic surveys require automated algorithms to optimize their observing strategy. One of the most ambitious upcoming spectroscopic surveys is the 4MOST survey. The 4MOST survey facility is a fibre-fed spectroscopic instrument on the VISTA telescope with a large enough field of view to survey a large fraction of the southern sky within a few years. Several Galactic and extr

Three-Dimensional Coherent Bragg Imaging of Rotating Nanoparticles

Bragg coherent diffraction imaging is a powerful strain imaging tool, often limited by beam-induced sample instability for small particles and high power densities. Here, we devise and validate an adapted diffraction volume assembly algorithm, capable of recovering three-dimensional datasets from particles undergoing uncontrolled and unknown rotations. We apply the method to gold nanoparticles whi

Chronological age assessment in young individuals using bone age assessment staging and nonradiological aspects : Machine learning multifactorial approach

Background: Bone age assessment (BAA) is used in numerous pediatric clinical settings as well as in legal settings when entities need an estimate of chronological age (CA) when valid documents are lacking. The latter case presents itself as critical as the law is harsher for adults and granted rights along with imputability changes drastically if the individual is a minor. Traditional BAA methods

Health-related quality of life in transplant ineligible newly diagnosed multiple myeloma patients treated with either thalidomide or lenalidomide-based regimen until progression : A prospective, open-label, multicenter, randomized, phase 3 study

Data on the impact of long term treatment with immunomodulatory drugs (IMiD) on health-related quality of life (HRQoL) is limited. The HOVON-87/NMSG18 study was a randomized, phase 3 study in newly diagnosed transplant ineligible patients with multiple myeloma, comparing melphalan-prednisolone in combination with thalidomide or lenalidomide, followed by maintenance therapy until progression (MPT-T

Runaway and walkaway stars from the ONC with Gaia DR2

Theory predicts that we should find fast, ejected (runaway) stars of all masses around dense, young star-forming regions. N-body simulations show that the number and distribution of these ejected stars could be used to constrain the initial spatial and kinematic substructure of the regions. We search for runaway and slower walkaway stars within 100 pc of the Orion Nebula Cluster (ONC) using Gaia D

Influence of fast-track programs on patient-reported outcomes in total hip and knee replacement (THR/TKR) at Swedish hospitals 2011–2015 : an observational study including 51,169 THR and 8,393 TKR operations

Background and purpose — Fast-track care programs have been broadly introduced at Swedish hospitals in elective total hip and knee replacement (THR/TKR). We studied the influence of fast-track programs on patient-reported outcomes (PROs) 1 year after surgery, by exploring outcome measures registered in the Swedish arthroplasty registers. Patients and methods — Data were obtained from the Swedish K

Dynamic ElecTronic hEalth reCord deTection (DETECT) of individuals at risk of a first episode of psychosis : a case-control development and validation study

Background: Many individuals who will experience a first episode of psychosis (FEP) are not detected before occurrence, limiting the effect of preventive interventions. The combination of machine-learning methods and electronic health records (EHRs) could help address this gap. Methods: This case-control development and validation study is based on EHR data from IBM Explorys. The IBM Explorys Plat

The art of living with symptoms : A qualitative study among patients with primary brain tumors receiving proton beam therapy

Background: Symptom management in conjunction with proton beam therapy (PBT) from patient's perspective has not been explored. Such knowledge is essential to optimize the care in this relatively new treatment modality. Objective: The aim of this study was to explore the process of symptom management in patients with brain tumor receiving PBT. Methods: Participants were 22 patients with primary bra

Sustainable business model innovation : The role of boundary work for multi-stakeholder alignment

This study focuses on the boundary-spanning nature of sustainable business model innovation, studying multi-stakeholder engagement and alignment. Drawing on the concept of boundary work, we explore the different types of organizational boundary changes between focal companies and their external stakeholders, investigating specifically the process of exploring, negotiating, disrupting and realignin

The meaning of home questionnaire revisited : Psychometric analyses among people with Parkinson's disease reveals new dimensions

BACKGROUND: Research addressing perceptions of housing in people with Parkinson's disease (PD) is rare, and existing instruments capturing perceived aspects of housing are rarely used. Perceived housing comprises of several domains and is associated with health in general older populations. One such domain is meaning of home, captured by the Meaning of Home Questionnaire (MOH). The aim of this stu

Comprehensive lipidomics in apoM−/− mice reveals an overall state of metabolic distress and attenuated hepatic lipid secretion into the circulation

Apolipoprotein M (apoM) participates in both high-density lipoprotein and cholesterol metabolism. Little is known about how apoM affects lipid composition of the liver and serum. In this study, we systemically investigated the effects of apoM on liver and plasma lipidomes and how apoM participates in lipid cycling, via apoM knockout in mice and the human SMMC-7721 cell line. We used integrated mas

Studying particle production in small systems through correlation measurements in ALICE

In these proceedings, measurements of angular correlations between hadron pairs in pp collisions obtained by the ALICE experiment at the LHC are presented and compared with phenomenological predictions. Correlations between particles carrying the same and opposite quantum numbers are studied to understand the hadron production mechanism, and the difference between the same-sign and opposite-sign c

The effect of pH and salt on the molecular structure and dynamics of the skin

The ‘acid mantle’ of the human skin is considered crucial for several protective functions of the skin. It has been associated with numerous biological processes including enzymatic activities and barrier function for diffusional transport. The outer thin layer of the skin– the stratum corneum (SC) - is primarily responsible for the skin barrier function. In this paper, we investigate how the stru

A practical framework and online tool for mutational signature analyses show intertissue variation and driver dependencies

Mutational signatures are patterns of mutations that arise during tumorigenesis. We present an enhanced, practical framework for mutational signature analyses. Applying these methods to 3,107 whole-genome-sequenced (WGS) primary cancers of 21 organs reveals known signatures and nine previously undescribed rearrangement signatures. We highlight interorgan variability of signatures and present a way

High genetic contribution to anterior cruciate ligament rupture : Heritability ∼69%

Objectives: We aimed to determine the lifetime genetic risk for anterior cruciate ligament (ACL) rupture. Methods: We used a twin study approach, linking the Swedish Twin Register with national healthcare data to form a 30 year, population wide, longitudinal twin cohort. We studied ACL rupture in this cohort of 88 414 identical and fraternal twin pairs, aged ≥17 years, to determine the familial ri

Mechanisms involved in regulation of periodontal ligament cell production of pro-inflammatory cytokines : Implications in periodontitis

It is well recognized that human periodontal ligament cells (PDL cells) may represent local immune cells of the periodontal tissues. However, it is unclear whether they represent “true” immune cells, since they can produce pro-inflammatory cytokines not only after stimulation with bacterial lipopolysaccharides but also in response to other stimuli such as mechanical stress. Stimulation with bacter

Experiments on Belief Formation in Networks

We study belief formation in social networks using a laboratory experiment. Participants in our experiment observe an imperfect private signal on the state of the world and then simultaneously and repeatedly guess the state, observing the guesses of their network neighbors in each period. Across treatments we vary the network structure and the amount of information participants have about the netw
