The Transparency Imperative : The Need for Model Documentation for Engaging with Public Policy following the EU AI Act
The application of Agent-Based Modeling and Simulation (ABMS) has few established guidelines and often suffers from insufficient model documentation. We assess the prevalence of best practices associated with different types of model documentation in light of the European Union’s AI Act (AI Act). Our analysis reveals that best practices are often implemented together but ultimately reinforce the p
The Ordovician of Scandinavia: a revised regional stage classification
The Ordovician of Scandinavia (i.e. Denmark, Norway and Sweden) has been investigated for over two centuries and, through time, various chronostratigraphic schemes have been introduced, facilitating regional correlation. However, a modern chronostratigraphy has never been proposed. Here, we delineate ten regional stages for the Ordovician of Scandinavia, comprising, in ascending order, the Slemmes
A point process on the unit circle with antipodal interactions
We introduce the point process [Formula presented] where Zn is the normalization constant. This point process is attractive: it involves n dependent, uniformly distributed random variables on the unit circle that attract each other. (For comparison, the well-studied CβE involves n uniformly distributed random variables on the unit circle that repel each other.) We consider linear statistics of the
Indole-3-propionic acid promotes hepatic stellate cells inactivation
Background & aims: We have previously reported that the serum levels of gut-derived tryptophan metabolite indole-3-propionic acid (IPA) are lower in individuals with liver fibrosis. Now, we explored the transcriptome and DNA methylome associated with serum IPA levels in human liver from obese individuals together with IPA effects on shifting the hepatic stellate cell (HSC) phenotype to inactiv
Uncharacterized members of the phylum Rozellomycota dominate the fungal community of a full-scale slow sand filter for drinking water production.
Slow sand filters (SSFs) for drinking water production are habitats for diverse microbes from multiple domains of life, which are integral to the ability of SSFs to purify water. While cultivation-independent analyses of the prokaryotic communities of SSFs have provided valuable insights, little attention has been paid to fungi inhabiting SSFs. This study characterized the fungal communities in th
Statistical documentation for multi-disease, multi-domain platform trials : our experience with the Staphylococcus aureus Network Adaptive Platform trial
Platform trials have become widely adopted across multiple disease areas over recent years, however, guidelines for operationalising these trials have not kept pace. We outline a series of documents that summarise the statistical components, and implicit processes, of the Staphylococcus aureus Network Adaptive Platform (SNAP) trial to provide an informal template for other researchers and reviewer
Increased risk of postoperative complications after delayed stoma reversal : a multicenter retrospective cohort study on patients undergoing anterior resection for rectal cancer
Purpose: Defunctioning stoma (DS) has been suggested to mitigate the consequences of anastomotic leak (AL) after low anterior resection. Stoma reversal (SR) is commonly delayed for nonmedical reasons in many healthcare systems. This study investigated the impact of the elapsed time from AR to SR on postoperative 90-day complications. The secondary aim was to explore the independent factors associa
Rapid ER remodeling induced by a peptide-lipid complex in dying tumor cells
The membranous ER spans the entire cell, creating a network for the biosynthesis of proteins and lipids, cell-wide communication, and nuclear delivery of molecules, including therapeutic agents. Here, we identify a novel ER response triggered by the tumoricidal complex alpha1-oleate, defined by a loss of peripheral ER structure, extensive ER vesiculation. Alpha1-oleate was present in the ER-derive
Foreign ownership and board cultural diversity
Using detailed hand-collected data on firm ownership and board cultural diversity from Sweden, we find that foreign ownership is positively associated with board cultural diversity. This relationship is not an artifact of foreign owners joining the board, and it is not driven by firms with substantial foreign focus. The presence of foreign owners on nomination committees seems to be the channel th
Antisecretory factor in severe traumatic brain injury (AFISTBI) : protocol for an exploratory randomized placebo-controlled trial
Background: Despite recent advances in neuroimaging and neurocritical care, severe traumatic brain injury (TBI) is still a major cause of severe disability and mortality, with increasing incidence worldwide. Antisecretory factor (AF), commercially available as Salovum®, has been shown to lower intracranial pressure (ICP) in experimental models of, e.g., TBI and herpes encephalitis. The aim of this
Queer Vietnam : An Introduction
Inspired by the workshop "Sacred Canopies: LGBT+, Buddhism, and Economics in Vietnam,"hosted at the University of Copenhagen in November 2023, this introduction frames the themes of the special issue. It focuses on how Vietnam's globalized market economy is shaping LGBTQI+ aspirations, mobilizations, personhoods, and spiritual experiences. It explores how the articles in this special issue shed ne
Simple and general bounds on quantum random access codes
Random access codes are a type of communication task that is widely used in quantum information science. The optimal average success probability that can be achieved through classical strategies is known for any random access code. However, only a few cases are solved exactly for quantum random access codes. In this paper, we provide bounds for the fully general setting of n independent variables,
Spatial distribution of tertiary lymphoid structures in the molecular and clinical context of non-small cell lung cancer
Introduction: Tertiary lymphoid structures (TLS) are lymphocyte aggregates resembling secondary lymphoid organs and are pivotal in cancer immunity. The ambiguous morphological definition of TLS makes it challenging to ascertain their clinical impact on patient survival and response to immunotherapy. Objectives: This study aimed to characterize TLS in hematoxylin-eosin tissue sections from lung can
Extra-uterine placental transfusion and intact-cord stabilisation of infants in caesarean sections : an intervention development and pilot-study (INTACT-1)
Background: Keeping the umbilical cord intact the first minutes after delivery is beneficial for both term and preterm infants. However, this may be challenging in caesarean sections (CS) due to lack of mobile resuscitation equipment, maintenance of sterility or concern for excessive maternal blood loss. The objective of this study was to develop and pilot-test extra-uterine placental transfusion
Current challenges in lung transplantation
Lung transplantation remains the definitive treatment for end-stage lung disease, but several critical challenges persist. Key issues include the limited availability of donor organs, ongoing debates over optimal preservation methods, and the controversy surrounding the best intraoperative support systems. Additionally, the efficacy of bridging strategies to transplantation continues to be questio
Evaluation of laser diffraction as a fast method for particle size distribution measurement of plant cell structures in whole oat and soy beverages
In food engineering in general and in liquid food processing specifically, accurate measurement of particle size is important, both for product development and daily quality control. Laser diffraction is the dominating method for particle size measurement of e.g., plant cell structures in food and beverage processing. However, the accuracy of the method can be questioned since these particles diff
A CFD-based approach to study cavitation in high-pressure homogenizer valves. Part 1. Cavitation inception, extent and location
Hydrodynamic cavitation occurs in high-pressure homogenizer (HPH) valves, causes wear and influences emulsification. Substantial advances have previously been made studying HPH cavitation in experimental systems. However, there is a lack of understanding on how cavitation develops in industrially relevant valves. The series applies CFD to address this knowledge gap. This part combines a previously
Compression of Entanglement Improves Quantum Communication
Shared entanglement can significantly amplify classical correlations between systems interacting over a limited quantum channel. A natural avenue is to use entanglement of the same dimension as the channel because this allows for unitary encodings, which preserve global coherence until a measurement is performed. Contrasting this, a distributed task based on a qubit channel is demonstrated, for wh
