Marine dimethyl sulfide (DMS) emissions are the dominant source of natural sulfur in the atmosphere. DMS oxidizes to produce low-volatility acids that potentially nucleate to form particles that may grow into climatically important cloud condensation nuclei (CCN). In this work, we utilize the chemistry transport model ADCHEM to demonstrate that DMS emissions are likely to contribute to the majorit

In this paper we present the differentiable log-Mel spectrogram (DMEL) for audio classification. DMEL uses a Gaussian window, with a window length that can be jointly optimized with the neural network. DMEL is used as the input layer in different neural networks and evaluated on standard audio datasets. We show that DMEL achieves a higher average test accuracy for sub-optimal initial choices of th

The important role of fire in regulating vegetation community composition and contributions to emissions of greenhouse gases and aerosols make it a critical component of dynamic global vegetation models and Earth system models. Over two decades of development, a wide variety of model structures and mechanisms have been designed and incorporated into global fire models, which have been linked to di

OBJECTIVES: To reach agreement among experts on visual assessments of postural orientation errors (POEs) during the single-leg squat (SLS), and to use expert agreement assessments as ground truth for machine learning (ML) models to evaluate their ability to classify POEs.DESIGN: Methodological study with mixed-methods design.METHODS: POEs of the lower extremity and trunk were assessed from videos

Background: The mitral valve is essential for proper heart function. Patient-specific simulations may provide insights into valve function and provide hemodynamic information for treatment planning. This study presents a framework for patient-specific mitral valve hemodynamic prediction and the validation of the simulation model against echocardiographic and MRI data. Methods: Ten healthy voluntee

We compared manual lymph drainage (MLD) with sequential pneumatic compression (SPC) for treatment of unilateral arm lymphedema in 28 women previously treated for breast cancer. After 2 weeks of therapy with a standard compression sleeve (Part I) with maintenance of a steady arm volume, each patient was randomly assigned to either one of two treatment regimens (Part II). MLD was performed according

Logistik som konkurrenskraft blir allt viktigare på dagens marknader, vilket medför att logistikföretagen idag erbjuder en bredare service än vad som gjorts tidigare. Vårt syfte är att undersöka problematiken mellan att erbjuda en hög servicenivå och att inneha en kostnadseffektiv organisation. Vi har valt att använda oss av en fallstudie på ett intermodalt transportföretag. Denna organisation har

Introduction: High vaccine uptake was crucial in preventing morbidity and mortality during the COVID-19 pandemic. The study aimed to investigate barriers and drivers of vaccination in Sweden across birth region groups with varying COVID-19 vaccine uptake.Methods: A cross-sectional anonymous survey was distributed non-randomly among individuals born in Sweden and immigrants from Western and non-Wes

Realistic depictions of past land cover are needed to investigate prehistoric environmental changes, effects of anthropogenic deforestation, and long term land cover-climate feedbacks. Observation based reconstructions of past land cover are rare and commonly used model based reconstructions exhibit considerable differences. Recently \citet[Spatial Statistics, 24:14--31,][]{PirzaLPG2018_24} develo

Wetlands in the boreal zone are a significant source of atmospheric methane, and hence they have been intensively studied with mechanistic models for the assessment of methane dynamics. The arctic-enabled dynamic global vegetation model LPJ-GUESS is one of the models that allow quantification and understanding of the natural methane fluxes at various scales ranging from local to regional and globa

Background and objective A high and equal vaccination coverage is of importance to prevent mortality and morbidity in society. The COVID-19 pandemic reminded us of societal inequities, reflected in differences in vaccine uptake. This plausibly influenced the disproportionate COVID-19-related mortality and morbidity among marginalised groups, groups that are underrepresented in research. Thus, our

Background and Objectives Keeping a small stock of liquid plasma readily available for transfusion is common practise in Sweden. We report data on complement activation markers in plasma components during storage in the liquid state and the kinetics of C3a-(desArg) after transfusion of autologous plasma with high content of C3a-(desArg) . Material and Methods Plasma components were prepared by aph
