Nanoscale heat engines are subject to large fluctuations which affect their precision. The thermodynamic uncertainty relation (TUR) provides a trade-off between output power, fluctuations, and entropic cost. This trade-off may be overcome by systems exhibiting quantum coherence. This Letter provides a study of the TUR in a prototypical quantum heat engine, the Scovil–Schulz-DuBois maser. Compariso
The pyruvate dehydrogenase complex (PDHc) links glycolysis to the citric acid cycle by converting pyruvate into acetyl-coenzyme A. PDHc encompasses three enzymatically active subunits, namely pyruvate dehydrogenase, dihydrolipoyl transacetylase, and dihydrolipoyl dehydrogenase. Dihydrolipoyl transacetylase is a multidomain protein comprising a varying number of lipoyl domains, a peripheral subunit
Background: Ménière's disease (MD) is a chronic peripheral vestibular disorder with recurrent episodes of vertigo accompanied by fluctuating hearing loss, tinnitus and aural fullness in the affected ear. There are several unanswered fundamental questions regarding MD, one of these being cortical activity during a MD attack. However, it is not possible to plan an investigation in an episodic diseas
To be an “author” might mean many different things, depending on the context in which the word is used. This thesis explores the EU copyright’s concept of author and how it relates to the everyday digital creativity on the Internet. It invites to consider what EU copyright law might look like if the digital creators which this thesis calls Creative Users were included in the legal system as “autho
The European Spallation Source (ESS) is a state-of-the-art neutron scattering facility, built on the outskirts of Lund in Southern Sweden, and expected to be taken into scientific operation in 2023. It is funded, run, and built by a consortium of thirteen (to date) European governments who jointly provide for its funding and establish its overarching governance principles, and it is co-hosted by S
Företag som ser sig om efter åtgärder för att minska sin klimatpåverkan och samtidigt stärka sitt varumärke bör undvika klimatkompensation i svenska skogar. Det skriver sex forskare.
Background: Second primary cancers (SPCs) are important clinically as they may negatively influence patient survival and they may tell about therapeutic side effects and general causes of cancer. Population-based literature concerning SPCs after hepatobiliary cancers is limited and here we assess risks of SPCs after hepatocellular cancer (HCC), and cancers of the gallbladder, bile ducts and ampull
Objective: Injuries to the wrist are, due to its small size and complex anatomical structures, difficult to assess by MR, and surgical interventions such as diagnostic arthroscopy are often necessary. Therefore, improved visualization using non-invasive methods could be of clinical value. As a first step of improvement, the purpose of this study was to evaluate visualization of anatomical structur
ObjectiveThe proportion of older people is increasing and reflects in the demand on ambulance services (AS). Patients can be more vulnerable and increasingly dependent, especially when their decision-making ability is impaired. Self-determination in older people has a positive relation to quality of life and can raise ethical conflicts in AS. Hence, the aim of this study was to empirically explore
Party politics and electoral research generally assume that party members are loyal voters. This article first assesses the empirical basis for this assumption before providing individual-level explanations for defection. It combines prominent theories from party politics and electoral behaviour research and argues that internal disagreement and external pressure can each bring about disloyal voti
Does ideological incongruence hurt parties in elections? Research on the representational relationship between parties and voters suggests that ideological congruence can boost a party’s electoral prospects. However, while the mechanism is at the individual-level, most of the literature focuses on the party-level. In this article, we develop a set of hypotheses based on a multi-issue conception of
