Polyploidy is an important driver of the evolution and diversification of flowering plants. Several studies have shown that established polyploids differ from diploids in floral morphological traits and that polyploidization directly affects these traits. However, for floral scent, which is key to many plant-pollinator interactions, only a few studies have quantified differences between establishe
Based on previous work, we extend a primal-dual semi-smooth Newton method for minimizing a general L^1-L^2-TV functional over the space of functions of bounded variations by adaptivity in a finite element setting. For automatically generating an adaptive grid, we introduce indicators based on a-posteriori error estimates. Further, we discuss data interpolation methods on unstructured grids in the
We consider waveform iterations for dynamical coupled problems, or more specifically, PDEs that interact through a lower-dimensional interface. We want to allow for the reuse of existing codes for the subproblems, called a partitioned approach. To improve computational efficiency, different and adaptive time steps in the subsolvers are advisable. Using so-called waveform iterations in combination
Purpose: Ovarian cancer ranks as a gynecological malignancy with poor prognosis, specifically if detected late. Primary treatment includes cytoreductive surgery and adjuvant chemotherapy with curative intent. Local anesthetics (LA) administered in the perioperative period may potentially impact patient outcome by several mechanisms. The beneficial impact of LA has been attributed, among other fact
Climate litigation is growing and increasingly targets corporate actors. Scientific evidence is crucial in climate court cases, for instance to determine plaintiffs’ standing to sue or the attribution of climate impacts to the defendants’ actions. However, it remains unknown how scientific expertise influences court decisions, what forms of expertise are used, how evidence is contested, and how ju
OBJECTIVE: Linear radiological measures have low sensitivity to detect changes in ventricular volume in patients with idiopathic normal pressure hydrocephalus. Ventricular volumetry is accurate and sensitive in detecting subtle changes in cerebrospinal fluid volumes. The Codman Certas® Plus is an adjustable shunt valve with 8 settings and resistant to magnetic resonance imaging (MRI)-induced inadv
Background: The international multi-center randomized controlled STEPCARE-trial will investigate optimal management of sedation, temperature, and mean arterial pressure (MAP) during intensive care in out-of-hospital cardiac arrest (OHCA) patients due to various etiologies. The primary outcome is mortality at 6 months. This protocol describes an extended follow-up sub-study of the STEPCARE-trial wi
Background: Focal cortical dysplasia (FCD) is a developmental cortical malformation and a leading cause of drug-resistant epilepsy that often requires epilepsy surgery. Some FCD patients experience acute postoperative seizures (APOS) following surgery. The relationship between APOS and long-term prognosis for patients with FCD is at present unclear. The primary aim of this study was to analyze the
Odor recognition memory (ORM) combines olfaction and episodic memory, both linked to dementia and impaired in Parkinson's Disease (PD). Measuring ORM may indicate early PD dementia and aid in selecting device-aided Parkinson therapy. This study investigates ORM capacity and hippocampal dynamic functional connectivity in PD. Thirty-one PD participants and 31 healthy controls (HC) underwent function
Background: Multiple clinical practice guidelines and head computed tomography decision rules exist for emergency department (ED) triage of children with traumatic brain injury (TBI). These vary in structure, aim, target cohort, and outcomes, yet are used clinically in similar populations. We compared important clinical and practical characteristics of all major guidelines in a large, real-world p
Market-based climate policies have received increased attention, making it important to understand how they affect competition in the electricity market. This paper focuses on the green certificate policy which financially supports producers of renewably sourced electricity by means of tradable certificates, and develops a duopoly model that incorporates both the electricity and the green certific
The European Association of Urology (EAU) 2021 prognostic model for non–muscle-invasive bladder cancer (NMIBC) is based on the World Health Organization (WHO) 1973 and/or WHO 2004/2022 grading systems for patients who did not receive bacillus Calmette-Guérin (BCG) instillations and is widely used to assess the risk of progression. The estimated risk of progression affects the type of adjuvant intr
Background: The multifactorial nature of chronic pain should be reflected in pain assessment. The aim of this observational study comparing samples from three generations assessed at different times was to present differences in pain, stress and mental well-being. Methods: Pain sites, widespread pain, stress (Perceived Stress Scale-4) and mental well-being (30-item General Health Questionnaire) we
Study region: The Limpopo River Basin (LRB) is a transboundary catchment in Southern Africa, shared by South Africa, Botswana, Zimbabwe, and Mozambique. The basin is increasingly affected by climate variability, land-use change, and rapid population growth, with the Chókwe floodplain in Mozambique representing a hotspot of socio-economic vulnerability to floods. Study focus: This study applies the
The importance of immunometabolism in the development of metabolic diseases is clear. Yet, how certain metabolic disorders, such as insulin deficiency (ID), influence immune cell function, and vice versa, is poorly understood. Also, therapeutic strategies to harness the interplay between immune cells and metabolism are lacking. Here, we observe that ID rearranges the immune landscape of the liver,
This article investigates the potential of alternative research terminologyto facilitate the utilisation of existing geographical conceptions of spaceand place in empirical studies of children’s everyday lives. This isachieved by employing Clifford Geertz’s (1974. “‘From the Native’s Pointof View’: On the Nature of Anthropological Understanding.” Bulletin ofthe American Academy of Arts and Science
Purpose:This paper aims to contribute to the understanding of the recirculation of products by empirically exploring, conceptualising and explaining how second-hand goods are made in practices and processes of valuation.Design/methodology/approach: The paper takes a practice theory approach to valuation and draws on an ethnographic study of ReTuna, a second-hand shopping mall, to explore the valua
This article discusses the interweaving of queerness, affect and translation in the asylum process, focusing on the role of legal representatives. Through 16 semi-structured interviews with asylum lawyers in Greece, it explores their collaborative work with queer asylum seekers in preparing a “credible” account. Approaching legal preparation as a process of translating applicants’ emotions into wh
OBJECTIVES: To describe the prevalence of cardiovascular disease (CVD) at the time of diagnosis of adult-onset type 1 (T1D) and type 2 (T2D) diabetes, in a recent cohort and compare to a previous cohort from the same region. Further, to explore factors influencing the prevalence of pre-existing CVD, including age, sex, body mass index (BMI) and C-peptide; in the later cohort also heart failure, hy
