In this paper, a novel decentralized leader-follower control scheme for multi–agent systems is devised, where each agent communicates only with a subset of neighboring mates. The goal is to track assigned trajectories for the centroid and the formation of the system. The desired trajectories are known only by a subset of agents, named leaders: the other agents, the followers, are required to estim

Introduction Forensic pathologists are frequently confronted with questions about whether an injury is likely to have been inflicted by an assault or be self-inflicted. However, little is known of the epidemiological variables that might be applicable to differentiate between homicides and suicides in deaths caused by single stab injuries to the trunk. Method Using the Swedish forensic autopsy reg
This book provides an overview of the history of knowledge, including its main currents, distinguishing ideas, and key concepts. However, it is not primarily a state-of-the-art overview but rather an argumentative contribution that seeks to push the field in a certain direction – towards studying knowledge in society and knowledge in people's lives. Hence, the history of knowledge envisioned by th
This article reviews some of the communicative strategies of plant-based meat, a food innovation that promises an experience akin to that of animal meat, but devoid from its harmful consequences relating to the well-being of humans, animals, and the planet. Mobilizing a constitutive approach on communication, we trace the founding narrative of the Beyond Meat firm using various documents, which en
The worldwide adoption of renewable energy mandates, together with the widespread utilization of biofuels has created a sharp increase in the production of biodiesel (fatty acid alkyl esters). As a consequence, the production of glycerol, the main by-product of the transesterification of fatty acids, has increased accordingly, which has led to an oversupply of that compound on the markets. Therefo
In this paper, we revisit the rotation averaging problem applied in global Structure-from-Motion pipelines. We argue that the main problem of current methods is the minimized cost function that is only weakly connected with the input data via the estimated epipolar geometries. We propose to better model the underlying noise distributions by directly propagating the uncertainty from the point corre
Aims: Mineralocorticoid receptor antagonists (MRAs) improve outcomes in heart failure with reduced ejection fraction (HFrEF) but remain underused and are often discontinued especially in patients with chronic kidney disease (CKD) due to concerns on renal safety. Therefore, in a real-world HFrEF population we investigated the safety of MRA use, in terms of risk of renal events, any mortality and an
Aims: Deep neural network artificial intelligence (DNN-AI)-based Heart Age estimations have been presented and used to show that the difference between an electrocardiogram (ECG)-estimated Heart Age and chronological age is associated with prognosis. An accurate ECG Heart Age, without DNNs, has been developed using explainable advanced ECG (A-ECG) methods. We aimed to evaluate the prognostic value
Objective: The purpose of this study was to determine whether alcohol use disorder (AUD) can be transmitted contagiously in siblings and likely acquaintances growing up close to one another (Propinquity-of-Rearing Defined Acquaintances [PRDAs]). Method: PRDAs were pairs of same-age subjects growing up within 1 km of each other and sharing the same school class, where one of whom (PRDA1) was first
Importance: Clinical studies confirm that obesity is a risk factor for recurrence in postmenopausal women with hormone receptor-positive (HR+) breast cancer. Evidence suggests that women with obesity do not obtain similar protection from aromatase inhibitors as women with healthy weight. Objective: To examine the associations of body mass index (BMI) with recurrence. Design, Setting, and Participa
Med utgångspunkt i ett fabelmotiv i Lunds domkyrkas korstolar - räven och storken som bjuder varandra på middag - tecknas fabelgenrens historia från medeltid till idag.
Background: Administration of various exogenous surfactant preparations has been shown to decrease lung injury and pneumothorax and improve survival in very preterm infants with respiratory distress syndrome (RDS). There is no consensus on the threshold for surfactant administration, to allow timely intervention and avoid over-treatment, also considering the invasiveness of the procedure and its c
The binocular field of vision differs widely in birds depending on ecological traits such as foraging. Owls (Strigiformes) have been considered to have a unique binocular field, but whether it is related to foraging has remained unknown. While taking into account allometry and phylogeny, we hypothesized that both daily activity cycle and diet determine the size and shape of the binocular field in
Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system caused by myelin-specific autoreactive T cells. We previously demonstrated intestinal barrier disruption and signs of inflammation in experimental autoimmune encephalomyelitis (EAE), a model of MS. Fecal calprotectin is a disease activity biomarker in inflammatory bowel diseases, released by neutrophils
The emergence of antibiotic resistance is a global health concern. Therefore, understanding the mechanisms of its spread is crucial for implementing evidence-based strategies to tackle resistance in the context of the One Health approach. In developing countries where sanitation systems and access to clean and safe water are still major challenges, contamination may introduce bacteria and bacterio
