Drainage networks delineated from Digital Elevation Models (DEMs), are the basis for the modelling of geomorphological and hydrological processes, biogeochemical cycling, and water resources management. Besides providing effective models of water flows, automatically extracted drainage networks based on topography can diverge from reality to varying degrees. The variability of such disagreement wi

Background: Gallbladder cancer (GBC) has a poor prognosis. The aim was to develop and validate a preoperative risk score for incidental gallbladder cancer (IGBC) in patients scheduled for cholecystectomy. Methods: Data registered in the nationwide Swedish Registry for Gallstone Surgery (GallRiks) was analyzed, including the derivation cohort (n = 28915, 2007–2014) and the validation cohort (n = 78

We report thermometry and new Raman linewidth data using a novel method for time-domain rotational coherent anti-Stokes Raman spectroscopy (RCARS) on single-shot basis. The coherences are generated by two fs pulses and probed by a ns pulse. The resulting signal is detected using a combined spectrograph/streak camera setup with high spectral and temporal resolution. Rotational CARS spectrograms of

Summary: Background: Diabetes mellitus (DM) is a risk factor for peripheral arterial disease (PAD). Indications for open surgery in infrainguinal intermittent claudication (IC) are limited, and reports are lacking regarding outcomes in DM patients. Study aims were to compare short and long-term effects on major adverse cardiovascular events (MACE), acute myocardial infarction (AMI), stroke, major

Background: The coronavirus disease 2019 (COVID-19) pandemic calls for effective and safe treatments. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing COVID-19 actively replicates in the throat, unlike SARS-CoV, and shows high pharyngeal viral shedding even in patients with mild symptoms of the disease. HCoV-229E is one of four coronaviruses causing the common cold. In this stu

Ammonia (NH3) is considered a promising alternative fuel, capable of producing energy with zero CO2 emissions. Its combustion, however, poses a series of challenges due to the low reactivity of NH3 and the formation of very high quantities of NOx. This work numerically investigates the combustion and emission characteristics of ammonia in three modern stationary gas turbine concepts, namely (a) le

Stochastic differential equation mixed-effects models (SDEMEMs) are flexible hierarchical models that are able to account for random variability inherent in the underlying time-dynamics, as well as the variability between experimental units and, optionally, account for measurement error. Fully Bayesian inference for state-space SDEMEMs is performed, using data at discrete times that may be incompl

Corona time is a time of buffering. This essay takes the pandemic, as it could be understood right before Christmas 2020, as its' point of departure. The essay is an audiovisual remix of the Mundania File "Waiting for Events":https://mundania.se/waiting-for-events/ and part of my ongoing research about "Connected Homes and Distant Infrastructures".

Objective: The aim of the current study was to examine whether health complaints and self-reported health were associated with bullying victimization in a large cohort of Icelandic children and adolescents. Methods: In this study, we used data from a school-based cross-sectional survey, specifically, the Icelandic contribution to the international research network Health Behavior in School-aged Ch

The aim of this paper is to show that logic programming is a powerful tool for representing scientific theories and for scientific inference. In a logic program it is possible to encode the qualitative and quantitative components of a theory in first order predicate logic, which is a highly expressive formal language. A theory program can then be handed to an algorithm that reasons about the theor

Although animals are born with a protective immune system, even the innate immune system is under development from birth to adulthood and this development may be affected by sex and growth. However, most knowledge comes from captive animals or long-lived slow growing species. Moreover, little is known about how innate immune function, the important first line of defence, develops during early life

Human beings are definitely storytellers capable of travel back and forward in time. We not only construct stories about ourselves, but also share these with others (McAdams and McLean 2013). We construct and internalize an evolving and integrative story for life, that is, a narrative identity (Singer 2004). However, the life story is just one of three layers of personality that are in a dynamical

Understanding the complex interplay of mass transport, heat transport and deformation in swelling cellulose based materials is a challenging task. To aid in this endeavour a multiphysics model is developed within the mixture theory framework. The model is macroscopic and accounts for swelling, non-equilibrium mass exchange of water, elastic deformation and multiphase transport phenomena, where non

The smart home around 2020 is based on interconnected software equipped things that through automation are supposed to deliver new pleasures and conveniences. This technological makeover of domestic settings is characterised by consumption of things that are promoted as novel and spectacular. If successful, these things are then gradually transformed into ignored infrastructure, into paraphernalia

Advanced treatment technologies for the removal of pharmaceuticals and other organic micropollutants in WWTPs primarily target the removal of parent compounds. Nevertheless, the removal of metabolites originating from human- or microbial metabolism during biological treatment needs comparable consideration, as some of them might be present in high concentrations and contribute to toxicity. This st

Nano-ceramic particles can serve as reinforcing agents for metallic materials to improve their mechanical properties. However, it is important to ensure chemical compatibility between the matrix and particles. In the present study, magnesium composites with and without nano-hydroxyapatite (nHA) particles were fabricated for bone reconstruction applications. Two different techniques were used, Conv

Mid-ranging control is a control strategy that is used when there are more than one manipulated variable available to control a process variable. Mid-ranging control handles the redundancy by coordinating the roles of the different manipulated variables. The most common approach is to introduce valve position controllers (VPC) that control the relations between the manipulated variables. In this p

Aims: Ingrowth bags are widely used to estimate mycorrhizal growth and dynamics. However, it remains unclear to what extent they reflect the surrounding soil, and how this varies with environmental conditions. Methods: We used a fertilization experiment to investigate if carbon-free mesh bags were representative of their surrounding soil. We determined AMF hyphal length density (HLD), phospholipid
