Improving the communication between teams managing boarded patients on a surgical specialty ward

Transferring patients from the ward of their specialty or consultant is described as boarding. 1 Boarding patients is becoming increasingly prevalent due to greater pressure on hospital capacity. This practice compromises patient safety through delayed investigations, prolonged hospital stays, and increased risk of hospital-acquired infections. 1 2 We evaluated how regularly boarded patients were

An empirical analysis of Measure-Valued Derivatives for policy gradients

Reinforcement learning methods for robotics are increasingly successful due to the constant development of better policy gradient techniques. A precise (low variance) and accurate (low bias) gradient estimator is crucial to face increasingly complex tasks. Traditional policy gradient algorithms use the likelihood-ratio trick, which is known to produce unbiased but high variance estimates. More mod

Adrenocorticotropic hormone-secreting phaeochromocytoma as a cause of treatment-resistant hypertension and recurrent pulmonary emboli

We report an unusual case of a patient presenting with Cushing’s syndrome caused by a phaeochromocytoma secreting adrenocorticotropic hormone (ACTH). The patient had a history of treatment-resistant hypertension, secondary amenorrhoea and tendency towards hypokalaemia. She had multiple signs of Cushing’s syndrome, such as swelling, bruising, abdominal striae and proximal myopathy. Hypokalaemia is

Deconstructing Security Discourse in Circular Economy Governance : Towards an Inclusive Approach to Circular Transformation

Global environmental challenges, coupled with growing material resource consumption, are exacerbated by an increasingly hostile geopolitical environment and the securitisation of politics. The circular economy (CE) proposes a solution to address these challenges by transforming production and consumption systems, which has sparked significant interest in the concept among scholars, policymakers, a

Evaluating the Design of a Comprehensive Nordic Hospital at Home Education–A Study Protocol

This study protocol outlines the test evaluation of the design of a comprehensive Nordic hospital at home (HaH) digital education program entitled “the Nordic Digital Health and Education” program (NorDigHE). The NorDigHE program aims to prepare healthcare professionals for healthcare provision in a HaH context. The program, developed by a Nordic consortium, spans five modules over 3.5 weeks of fu

Sharing knowledge in multi-task deep reinforcement learning

We study the benefit of sharing representations among tasks to enable the effective use of deep neural networks in Multi-Task Reinforcement Learning. We leverage the assumption that learning from different tasks, sharing common properties, is helpful to generalize the knowledge of them resulting in a more effective feature extraction compared to learning a single task. Intuitively, the resulting s

ImitationFlow : learning deep stable stochastic dynamic systems by normalizing flows

We introduce ImitationFlow, a novel Deep generative model that allows learning complex globally stable, stochastic, nonlinear dynamics. Our approach extends the Normalizing Flows framework to learn stable Stochastic Differential Equations. We prove the Lyapunov stability for a class of Stochastic Differential Equations and we propose a learning algorithm to learn them from a set of demonstrated tr

Graph-based design of hierarchical reinforcement learning agents

There is an increasing interest in Reinforcement Learning to solve new and more challenging problems, as those emerging in robotics and unmanned autonomous vehicles. To face these complex systems, a hierarchical and multi-scale representation is crucial. This has brought the interest on Hierarchical Deep Reinforcement learning systems. Despite their successful application, Deep Reinforcement Learn

The occurrence and co-occurrence of conflicts and negative acts and their associations with self-rated health, workability, and life-satisfaction : a cross-sectional study of Swedish school principals

ObjectiveAs part of our research on Swedish school principals, we examined the occurrence and co-occurrence of conflicts and five negative acts (i.e. harassment, sexual harassment, threats of violence or physical harm, physical violence, bullying), their attributed sources, and their associations with self-rated health, workability, and general life satisfaction among 2670 principals.ResultsDuring

Voice fatigue subtyping through individual modeling of vocal demand reponses

Recognizing individual variability is essential for developing targeted, personalized medical interventions. Vocal fatigue is a prevalent symptom and complaint among occupational voice users, but its identification has yielded mixed results. Vocal fatigue is a complex issue with heterogeneous biophysiological responses to vocal demands among individuals. This research aims to classify individuals

River flow response to changing electricity demand and centralized hydropower operations in the Paranapanema River basin, Brazil

Study region: The Paranapanema River Basin, located in southeastern Brazil, is characterized by a cascade of large hydropower plants regulated by a nationally coordinated dispatch system. This basin is a representative case of reservoir-regulated rivers in the country, where multiple dams interact to supply electricity while reshaping natural flow regimes. Study focus: This study examines hydropow

How crop models and government visions foreclose imaginaries of agroecological futures

Against the backdrop of the ecological crisis, food production systems will need to transform to ensure future food security. There are contrasting visions of what this transformation should look like. This paper scrutinizes these competing imaginaries of future agriculture and associated styles of anticipation in Tanzania. We find that both government visions and global crop models anticipate fut

Prevalence and risk factors of feeding difficulties in children with delayed reconstruction of esophageal atresia : a Swedish nationwide study

Purpose: Children with delayed reconstruction of esophageal atresia (DREA) have a high risk of morbidity. The aim of this study was to determine the prevalence of feeding difficulties in children with DREA, differences to children with primary anastomosis (PA) and identify risk factors for feeding difficulties in children with DREA. Methods: Parents of 30 children with DREA, born 2001–2018, were r

Conserved wing shape variation across biological scales unveils dialectical relationships between micro- and macroevolution

Variation enables short-term evolution (microevolution), but its role in long-term evolution (macroevolution) is debated. Here, we analyzed a dataset of Drosophila wing variation across six levels of biological organization to demonstrate that microevolutionary variation and macroevolutionary divergence are positively correlated at all levels from variation within an individual to macroevolution o

Charge regulation in peptide self-assembly and hydrogelation

The peptide Ac-KGSFSIQYTYHVD-CONH₂ (KD), derived from residues 37–49 of human semenogelin I, forms a pH-responsive hydrogel in an aqueous environment with tunable mechanical properties that evolve over time. We hypothesize that KD self-assembles into a hydrogel through a pH-dependent mechanism involving predominantly a change in histidine protonation state, leading to structural transformations th

The role of habit loop formation and social norms in promoting eco-friendly behavior: A study on reusable bag usage post plastic tax abolition

This study investigated the influence of habit strength and perceived social norms on Swedish residents continued use of reusable bags following the removal of the plastic bag tax. A cross-sectional survey (N = 93) measured participants’ habit strength, perception of social norms, and frequency of reusable bag usage. Descriptive statistics indicated variability in habit and social norm scores, and
