Background and Purpose: Diffusion-weighted MR imaging and fiber tractography can be used to investigate alterations in white matter tracts in patients with early acquired brain lesions and cerebral palsy. Most existing studies have used diffusion tensor tractography, which is limited in areas of complex fiber structures or pathologic processes. We explored a combined normalization and probabilisti
Purpose: The aim of the present study was to seek evidence of a relationship between damage to the optic radiation (OR) in the immature brain and subsequent development of the retinal nerve fiber layer (RNFL) and associated visual manifestations.Methods: Seven cases (2 males and 5 females ranging in age from 18 to 35 years old) were selected from a large cohort of individuals with known white matt
UNLABELLED: Diffusion MRI improves detection of abnormalities in white matter tracts in cerebral palsy (CP). Relationships between diffusion measurements and hand function are largely unexplored. We aimed first to assess microstructure of corticofugal fibers, and second to explore associations between tract injury as assessed by quantitative analysis of diffusion MRI and hand function in children
BACKGROUND: To describe visual field (VF) outcome in three adolescents with damage to the optic radiation and to focus on mechanisms that may compensate the practical functional limitations of VF defects.DESIGN: Descriptive, prospective multi-case study in a hospital setting.PARTICIPANTS: Three teenagers with cerebral visual dysfunction because of damage to the retro-geniculate visual pathways.MET
Allt sedan det amerikanska presidentvalet 2016 har det runt om i världen pågått en intensiv diskussion om utländska påverkansoperationer och hur och med vilken framgång främmande makter i det fördolda har sökt påverka demokratiska val, politisk opinion och politiska beslut i olika länder, däribland Sverige. Forskare, debattörer och politiker har särskilt framhållit att den nya informationsteknolog
Women have a 10% lifetime risk of developing breast cancer, and the disease has surpassed lung cancer as the most frequently diagnosed type of cancer in the world. Breast cancer originates in the epithelial cells of the mammary gland and tumor cells have undergone a series of genetic and phenotypic changes that confer tumor promoting properties.Genomic rearrangement is a common phenomenon in cance
Assemblies of different molecules is a prevalent phenomenon in nature, and crucial in biological life. Most of the biological assemblies are co-assembledcomposites, made up from several different components, either of thesame biomolecular type or a combination of different ones. Knowledge regarding amyloid fibril structure and the mechanism behind it has been elucidated through the development of
This chapter discusses broadly the challenges and opportunities for anthropologically engaging with the news media during a pandemic. It explores the Swedish experience, describing how the country was portrayed as reckless and irresponsible and the ways in which Swedish culture was used and misused to explain its handling of the pandemic. Anthropologists rely on news sources, to “set the scene,” t
BACKGROUND: There are multiple options for the treatment of thumb carpometacarpal joint osteoarthritis (CMC1 OA), with evidence for pain relief and improved function. Although simple trapeziectomy has the lowest complication risk, tendon suspension of the first metacarpal and interposition is still the most commonly used surgical procedure in patients with CMC1 OA. Although there are several repor
We study fully differential quarkonia photoproduction observables in ultraperipheral collisions as functions of momentum transfer squared. We employ the dipole picture of the QCD part of the scattering with proton and nucleus targets, with the projectile being a quasireal photon flux emitted by an incoming hadron. We analyze such observables for ground J/ψ, (1S) and excited ψ′, (2S) states whose l
Wurtzite-type zinc oxide (w-ZnO) is a widely used material with a pronounced structural anisotropy along the c axis, which affects its lattice dynamics and represents a difficulty for its accurate description using classical models of interatomic interactions. In this study, ab initio molecular dynamics (AIMD) was employed to simulate a bulk w-ZnO phase in the NpT ensemble in the high-temperature
Background: By 2030, the global population of people older than 60 years is expected to be higher than the number of children under 10 years, resulting in major health and social care system implications worldwide. Without a supportive environment, whether social or built, diminished functional ability may arise in older people. Functional ability comprises an individual's intrinsic capacity and p
Context. Young open clusters (ages of less than 200 Myr) have been observed to exhibit several peculiarities in their chemical compositions. These anomalies include a slightly sub-solar iron content, super-solar abundances of some atomic species (e.g. ionised chromium), and atypical enhancements of [Ba/Fe], with values up to ~0.7 dex. Regarding the behaviour of the other s-process elements like yt
Context. After more than 50 years, astronomical research still struggles to reconstruct the history of lithium enrichment in the Galaxy and to establish the relative importance of the various 7Li sources in enriching the interstellar medium (ISM) with this fragile element. Aims. To better trace the evolution of lithium in the Milky Way discs, we exploit the unique characteristics of a sample of op
The investigation of the phenomenon of dephasing assisted quantum transport, which happens when the presence of dephasing benefits the efficiency of this process, has been mainly focused on Markovian scenarios associated with constant and positive dephasing rates in their respective Lindblad master equations. What happens if we consider a more general framework, where time-dependent dephasing rate
In this review, we provide a short outlook of some of the current most popular pictures and promising approaches to non-perturbative physics and confinement in gauge theories. A qualitative and by no means exhaustive discussion presented here covers such key topics as the phases of QCD matter, the order parameters for confinement, the central vortex and monopole pictures of the QCD vacuum structur
Safe water and sanitation, which give rise to appropriate hygiene, are fundamental determinants of individual and social health and well-being. Thereby, assessing and widening access to sustainable, durable water and sanitation infrastructure remains a global health issue. Rural areas are already at a disadvantage. Poor access to water, sanitation, and hygiene (WASH) can have a major negative effe
Despite the growing surge in the literature about employee creativity, the mainstream literature largely views it from an organizational perspective, and ignores the underlying mechanism that motivates employees to be engaged in different creative tasks. Against this backdrop, the current work was carried out to explore the relationship of corporate social responsibility (CSR) and employee creativ
Global aging has raised increasing concerns on the health and well-being of older adults. Public transport is a viable option to improve the mobility and quality of life among older adults. However, policies that promote the public transport use among older adults are rare. This study utilizes the eXtreme Gradient Boosting (XGBoost) decision tree to explore the non-linear associations of the built
