Cortical changes during the learning of sequences of simultaneous finger presses

The cortical alterations underpinning the acquisition of motor skills remain debated. In this longitudinal study in younger adults, we acquired performance and neuroimaging (7T MRI) measures weekly over the course of 6 weeks to investigate neural changes associated with learning sequences of simultaneous finger presses executed with the non-dominant hand. Both the intervention group (n = 33) and t

Childhood Cancer Survivors Have Impaired Strain-Derived Myocardial Contractile Reserve by Dobutamine Stress Echocardiography

Abnormal left ventricular contractile reserve (LVCR) is associated with adverse cardiac outcomes in different patient cohorts and might be useful in the detection of cardiomyopathy in childhood cancer survivors (CCS) after cardiotoxic treatment. The aim of this study was to evaluate LVCR by dobutamine stress echocardiography (DSE) combined with measures of myocardial strain in CCS previously treat

Automated detection of tool wear in machining and characterization of its shape

Flank wear VBmax remains one of the most essential and used metrics for measuring tool wear. VBmax is used to characterize tool wear rate, machinability of materials, the quality of machined surface. While VBmax measures the size of wear scar, the shape of the tool wear remains less used but not the least applicable for such characterization. However, quantification of the wear shape requires a mo

Characterization of therapy-related acute myeloid leukemia : increasing incidence and prognostic implications

Studies of therapy-related AML (t-AML) are usually performed in selected cohorts and reliable incidence rates are lacking. In this study, we characterized, defined the incidence over time and studied prognostic implications in all t-AML patients diagnosed in Sweden between 1997 and 2015. Data were retrieved from nationwide population-based registries. In total, 6,779 AML patients were included in

Swedish journalists' perceptions of legal protection against unlawful online harassment

This study examined journalists' perceptions regarding the legal system's ability to protect them against online harassment. By utilizing open-ended survey responses from respondents with varying levels of trust in the legal system, the findings suggested a need for increased technical proficiency, resources, and priority within the legal system to adequately address the issue. Additionally, a rec

A molecular dynamics study on the influence of vacancies and interstitial helium on mechanical properties of tungsten

Tungsten is a prime candidate material for use in plasma facing components in nuclear fusion reactors. This would entail weathering extreme conditions, such as high thermal loads and particle bombardment. It is of vital importance to understand how tungsten mechanically responds to these conditions, and how it is impacted by the defects that form. The current communication considers how the mechan

Integration of Ferroelectric HfO2 onto a III-V Nanowire Platform

The discovery of ferroelectricity in CMOS-compatible oxides, such as doped hafnium oxide, has opened new possibilities for electronics by reviving the use of ferroelectric implementations on modern technology platforms. This thesis presents the ground-up integration of ferroelectric HfO2 on a thermally sensitive III-V nanowire platform leading to the successful implementation of ferroelectric tran

Assessment of exposure determinants and exposure levels by using stationary concentration measurements and a probabilistic near-field/far-field exposure model

Background: The Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation requires the establishment of Conditions of Use (CoU) for all exposure scenarios to ensure good communication of safe working practices. Setting CoU requires the risk assessment of all relevant Contributing Scenarios (CSs) in the exposure scenario. A new CS has to be created whenever an Operatio

Quantification of the inhaled deposited dose during sand and dust storms

Exposure to dust particles during a sand and dust storm (SDS) can be harmful for health. The first step to understand the health effects of such exposure is to quantify the amount of deposited dust particles in the respiratory tracts. In this book chapter, a brief summary is presented about: (1) the outbreak mechanisms dust particles and being airborne, (2) physical and chemical characteristics of

The First Practical Guide to Inflation Targeting

When Sweden left the gold standard on September 27, 1931, the Swedish government declared that the aim of monetary policy should be to stabilize the domestic purchasing power of the Swedish currency, the krona. With this step, price level targeting officially became for the first time the goal for a central bank. Soon after, the Riksbank (Bank of Sweden) sent a questionnaire to three prominent eco

Formalin-free fixation and xylene-free tissue processing preserves cell-hydrogel interactions for histological evaluation of 3D calcium alginate tissue engineered constructs

Histological evaluation of tissue-engineered products, including hydrogels for cellular encapsulation, is a critical and invaluable tool for assessing the product across multiple stages of its lifecycle from manufacture to implantation. However, many tissue-engineered products are comprised of polymers and hydrogels which are not optimized for use with conventional methods of tissue fixation and h

Hybridorganisationer

Begreppet hybrid har formligen exploderat och man kan knappt läsa en tidning eller en produktannons i dag utan att stöta på detta ord. Åtskilliga studier inom ämnen som företagsekonomi, organisationssociologi och statsvetenskap säger sig också handla om just hybridorganisationer. Samtidigt uppstår då frågan vad begreppet egentligen tillför och om det bidrar till vår förståelse av organisationer. K
