Mutation testing optimisations using the Clang front-end

Mutation testing is the state-of-the-art technique for assessing the fault detection capacity of a test suite. Unfortunately, a full mutation analysis is often prohibitively expensive. The CppCheck project for instance, demands a build time of 5.8 min and a test execution time of 17 s on our desktop computer. An unoptimised mutation analysis, for 55,000 generated mutants took 11.8 days in total, o

Oxygen Exposure and Tolerance Shapes the Cell Wall-Associated Lipids of the Skin Commensal Cutibacterium acnes

Cutibacterium acnes is one of the most abundant bacteria on the skin. Being exposed to oxygen and oxic stress, the secretion of the bacterial antioxidant protein RoxP ensures an endogenous antioxidant system for the preservation of skin health. To investigate the impact of the antioxidant RoxP on oxidation of the bacteria, wildtype and an isogenic roxp mutant were cultured in anaerobic and oxic co

Free heme and hemopexin in acute kidney injury after cardiopulmonary bypass and transient renal ischemia

Free heme is released from hemoproteins during hemolysis or ischemia reperfusion injury and can be pro-inflammatory. Most studies on nephrotoxicity of hemolysis-derived proteins focus on free hemoglobin (fHb) with heme as a prosthetic group. Measurement of heme in its free, non-protein bound, form is challenging and not commonly used in clinical routine diagnostics. In contrast to fHb, the role of

Affording excellence : What does excellence funding do for researchers?

The ambitions to fund excellent researchers and path-breaking research unite a whole family of funding instruments ranging from Centres of Excellence to individual grants. While instruments aimed at funding excellence share a number of commonalities, there are important subsidiary features which determine their overall efficacy. The paper uses a case study of the Swedish Distinguished Professor Gr

Mapping of peatlands in the forested landscape of Sweden using lidar-based terrain indices

Globally, northern peatlands are major carbon deposits with important implications for the climate system. It is therefore crucial to understand their spatial occurrence, especially in the context of peatland degradation by land cover change and climate change. This study was aimed at mapping peatlands in the forested landscape of Sweden by modelling soil data against lidar-based terrain indices.

The Environmental Gaze : Visual perspectives on monitoring landscapes of ecological devastation

The increasing application of monitoring technologies and the specific perspectives afforded through them are transforming our understanding of and relationship to our environment. Through systems of mass data accrual, the physical processes and elemental attributes of regional and planetary landscapes are transformed into media, such as digital multilayered maps, graphs, thermal imaging, models,

Real-world analysis of MET exon 14 mutations in non-small cell lung cancer : a retrospective study from two Swedish hospitals

Background: Real-World evidence on mesenchymal-epithelial transition exon 14 skipping mutations (METex14) in lung cancer remains limited. With an incidence of 3–4% across histological subtypes, METex14 is now an actionable target for MET inhibitors (METi) in advanced lung cancer, demonstrating response rates between 30–70%. Yet, its role in early stages and sensitivity to immune checkpoint inhibit

Increasing global ecosystem respiration between 1982 and 2015 from Earth observation-based modelling

Aim: Earth observation-based estimates of land–atmosphere exchange of carbon are essential for understanding the response of the terrestrial biosphere to climatic change and other anthropogenic forcing. Temperature, soil water content and gross primary production are the main drivers of ecosystem respiration (Reco), and the main aims of this study are to develop an Reco model driven by long-term g

Impaired artery elasticity predicts cardiovascular morbidity and mortality- A longitudinal study in the Vara-Skövde Cohort

It is still debated whether arterial elasticity provides prognostic information for cardiovascular risk beyond blood pressure measurements in a healthy population. To investigate the association between arterial elasticity obtained by radial artery pulse wave analysis and risk for cardiovascular diseases (CVD) in men and women. In 2002–2005, 2362 individuals (men=1186, 50.2%) not taking antihypert

Att införa styrmedel : Utmaningar och möjligheter för klimatpolitiken

En ambitiös politik och effektiva styrmedel behövs för en snabb klimatomställning av samhället. Det finns en stor palett av möjliga styrmedel och olika styrmedel fungerar olika bra beroende på vilka hinder för omställningen de är tänkta att hantera. Men även om det i stort är känt vad som behöver göras, vilka styrmedel som finns tillgängliga och hur de bäst kan användas är en annan fråga hur dessa

Anisotropy Parameters for Two-Color Photoionization Phases in Randomly Oriented Molecules : Theory and Experiment in Methane and Deuteromethane

We present combined theoretical and experimental work investigating the angle-resolved phases of the photoionization process driven by a two-color field consisting of an attosecond pulse train and an infrared pulse in an ensemble of randomly oriented molecules. We derive a general form for the two-color photoelectron (and time-delay) angular distribution valid also in the case of chiral molecules

From biochemical markers to molecular endotypes of osteoarthritis : a review on validated biomarkers

Introduction: Osteoarthritis (OA) affects over 500 million people worldwide. OA patients are symptomatically treated, and current therapies exhibit marginal efficacy and frequently carry safety-risks associated with chronic use. No disease-modifying therapies have been approved to date leaving surgical joint replacement as a last resort. To enable effective patient care and successful drug develop

Go out or stress out? Exploring nature connectedness and cumulative stressors as resilience and vulnerability factors in different manifestations of climate anxiety

Given the increasing severity of the climate crisis and, with it, rising climate anxiety, it is imperative to understand what climate anxiety is, how it functions, and how people can cope with it constructively. Nevertheless, research has often mixed different conceptualizations and operationalizations of climate anxiety, yielding sometimes seemingly contradictory findings. This study contributes

Characterizing the effects of extreme heat events on all-cause mortality : a case study in Ahmedabad city of India, 2002–2018

Recent years have seen a rise in extreme heat event (EHE)-related deaths in India. However, the impact of specific temperature thresholds on health risks remains understudied. Using Distributed Lag Non-Linear Models (DLNM), we explored the link between EHEs, defined by various temperature thresholds, and mortality risk in Ahmedabad, India, from 2002 to 2018, considering a 21-day lag. We observed a

Reference Implementation of the PID Controller

The PID controller is the by far most frequently employed type of controller. As you read, billions of digitally implemented PID controllers are running, shaping the dynamic behavior of anything from the fan speed in your laptop to safety-critical components in nuclear power plants. Given the abundance of commissioned PID controllers, it is surprisingly hard to find a single source that provides a

Dynamical modeling of physiology

Human physiology is the study of how organisms, organ systems, and individual organs function under normal circumstances. As a consequence of its paramount importance to medicine, physiology has been studied since ancient times, but the models studied in this book follow the tradition of modern physiology pioneered by Claude Bernard in the mid 1800s.The focus of the book lies on how dynamical mech
