Trading on peer-to-peer tourist accommodation platforms requires a sufficient level of trust between individual consumers and service providers. This is often achieved by using mutual consumer–provider evaluations, which are perceived as a trustworthy resource for information about upcoming stays. A variety of mechanisms and metrics are used to facilitate trust building on platforms; however, trus
Norm enforcement may be important for resolving conflicts and promoting cooperation. However, little is known about how preferred responses to norm violations vary across cultures and across domains. In a preregistered study of 57 countries (using convenience samples of 22,863 students and non-students), we measured perceptions of the appropriateness of various responses to a violation of a cooper
For over 300 million years, insects have relied on symbiotic microbes for nutrition and defence. However, it is unclear whether specific ecological conditions have repeatedly favoured the evolution of symbioses, and how this has influenced insect diversification. Here, using data on 1,850 microbe–insect symbioses across 402 insect families, we found that symbionts have allowed insects to specializ
Little is known about long-term quality of life (QOL) and functional status after pulmonary endarterectomy (PEA) for chronic thromboembolic pulmonary hypertension (CTEPH). We investigated QOL and functional status late after PEA. All patients who underwent PEA for CTEPH 1993–2020 at one Swedish center were included. Baseline characteristics and data from right heart catheterization, 6-min walk tes
This paper explores how landscape can be used as a lens to understand lingering as a geographical concept. Following the European Landscape Convention, landscape is defined as “an area, as perceived by people, whose character is the result of the action and interaction of natural and/or human factors”. Thus, landscape assembles practices, perceptions and natural processes in an a-modern manner; th
We investigate the impact of nonvanishing net charge in collision systems on measurements of balance functions and their integrals. We show that the nominal balance function definition yields integrals that deviate from unity because of the nonvanishing net charge. However, the integral of unified balance functions is shown to appropriately converge to unity when measured in a sufficiently wide ex
Somatic mutations in blood indicative of clonal hematopoiesis of indeterminate potential (CHIP) are associated with an increased risk of hematologic malignancy, coronary artery disease and all-cause mortality. Here we analyze the relation between CHIP status and incident peripheral artery disease (PAD) and atherosclerosis, using whole-exome sequencing and clinical data from the UK Biobank and the
We theoretically investigate the extractable work in single molecule unfolding-folding experiments with applied feedback. Using a simple two-state model, we obtain a description of the full work distribution from discrete to continuous feedback. The effect of the feedback is captured by a detailed fluctuation theorem, accounting for the information aquired. We find analytical expressions for the a
The nervous mechanisms for bladder emptying and urine storage involve a complex pattern of afferent and efferent signaling in parasympathetic, sympathetic, and somatic nerves. During voiding, contraction of the detrusor muscle is preceded by a relaxation of the outlet region, thereby facilitating the bladder emptying. Kim et al. found that 14 of 31 patients with overactive bladder (OAB) and noctur
Purpose: Compared with conventional dose rate irradiation (CONV), ultrahigh dose rate irradiation (UHDR) has shown superior normal tissue sparing. However, a clinically relevant widening of the therapeutic window by UHDR, termed “FLASH effect”, also depends on the tumor toxicity obtained by UHDR. Based on a combined analysis of published literature, the current study examined the hypothesis of tum
Purpose: Reduction in iodinated contrast medium (CM) dose is highly motivated. Our aim was to evaluate if a 50% reduction of CM, while preserving image quality, is possible in brain CT angiography (CTA) using virtual monoenergetic images (VMI) on spectral CT. As a secondary aim, we evaluated if VMI can salvage examinations with suboptimal CM timing. Methods: Consecutive patients older than 18 year
Introduction: Secondary tumoral parkinsonism is a rare phenomenon that develops as a direct or indirect result of brain neoplasms or related conditions. Objectives: The first objective was to explore to what extent brain neoplasms, cavernomas, cysts, paraneoplastic syndromes (PNSs), and oncological treatment methods cause parkinsonism. The second objective was to investigate the effect of dopamine
Objective: To validate Vergouwe's prediction model using the Swedish and Norwegian Testicular Cancer Group (SWENOTECA) RETROP database and to define its clinical utility. Materials and methods: Vergouwe's prediction model for benign histopathology in post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) uses the following variables: presence of teratoma in orchiectomy specimen; pre-ch
The next years will see the completion of the radioactive ion beam facility SPES (Selective Production of Exotic Species) and the upgrade of the accelerators complex at Istituto Nazionale di Fisica Nucleare – Legnaro National Laboratories (LNL) opening up new possibilities in the fields of nuclear structure, nuclear dynamics, nuclear astrophysics, and applications. The nuclear physics community ha
Fructans—fructose-based oligo- or polysaccharides—are de novo synthesized from sucrose by transfructosylating enzymes of microorganisms and plants. Fructan-producing enzymes belong to glycoside hydrolase families 32 and 68. Levansucrases, inulosucrases, some invertases, sucrose:sucrose 1-fructosyl transferases, fructan:fructan 1-fructosyl transferases, sucrose:fructan 6-fructosyl transferases and
Background: Road vehicle transportation is essential to support community access and participation for all children. However, little is known about the transport patterns of children with disabilities and medical conditions and their caregivers’ experiences supporting them to be transported safely in road vehicles in Australia. Aim: To understand the transport needs of children with disabilities a
