Natural and technological networks exhibit dynamics that can lead to complex cooperative behaviors, such as synchronization in coupled oscillators and rhythmic activity in neuronal networks. Understanding these collective dynamics is crucial for deciphering a range of phenomena from brain activity to power grid stability. Recent interest in co-evolutionary networks has highlighted the intricate in

We analyze the Boussinesq equation on the line with Schwartz initial data belonging to the physically relevant class of global solutions. In a recent paper, we determined ten main asymptotic sectors describing the large (x,t)-behavior of the solution, and for each of these sectors we provided the leading order asymptotics in the case when no solitons are present. In this paper, we give a formula v

In this work, we consider the problem of coordinating a collection of nth-order integrator systems. The coordination is achieved through the novel serial consensus design; this control design achieves a stable closed-loop system while adhering to the constraint of only using local and relative measurements. Earlier work has shown that second-order serial consensus can stabilize a collection of dou

This paper presents a novel control design for vehicular formations as an alternative to alignment through conventional consensus protocols for second-order systems. The design is motivated by the closed-loop system, which we construct as first-order systems connected in series, and is therefore called serial consensus. The serial consensus design will guarantee the stability of the closed-loop sy

The evolution of whole-body endothermy occurred independently in dinosaurs and mammals and was associated with some of the most significant neurocognitive shifts in life's history. These included a 20-fold increase in neurons and the evolution of new brain structures, supporting similar functions in both lineages. We propose the endothermic brain hypothesis, which holds that elaborations in endoth

Background: Affectivity has been suggested as a complex adaptive meta-system composed of positive affect and negative affect, two independent but interrelated markers of well-being, that can be represented as four distinct affective profiles: self-fulfilling (high positive affect/low negative affect), high affective (high positive affect/high negative affect), low affective (low positive affect/lo

BackgroundPsoriatic arthritis (PsA) is a chronic arthritis affecting people with psoriasis. If untreated, it may lead to disability. Recommended drugs are non‐steroidal anti‐inflammatory drugs (NSAIDs), corticosteroids, conventional synthetic disease‐modifying anti‐rheumatic drugs (csDMARDs), biologic DMARDs (bDMARDs), and targeted synthetic DMARDs (tsDMARDs). Tumour necrosis factor inhibitors (TN

An important aspect of microbiological surveillance is the ability to access live viruses for microneutralization assays, which enables the study of viral characteristics and mechanisms in vitro and production of positive controls for diagnostic methods. During the COVID-19 pandemic, the Public Health Agency of Sweden established a protocol for the rapid collection of clinical samples and subseque

Protein engineering studies often suggest the emergence of completely new enzyme functionalities to be highly improbable. However, enzymes likely catalysed many different reactions already in the last universal common ancestor. Mechanisms for the emergence of completely new active sites must therefore either plausibly exist or at least have existed at the primordial protein stage. Here, we use res

Sub-THz deployment is challenging due to high propagation losses, necessitating dense deployment. To reduce cost, RF signal can be distributed via plastic fiber to remote radio units to increase coverage area. In this paper, we propose an antenna-in-package concept for the single-layer substrate on low-cost embedded wafer level ball grid array (eWLB) packages. To suppress the distortion in the bro

Mångfalden av våtmarker, vattendrag, sjöar och grundvatten samverkar i ett större perspektiv inom ett avrinningsområde. Funktioner som är sammankopplade och beroende av varandra. En holistisk förståelse av våtmarker utgår från att vi tar hänsyn till alla delar. En funktion forskarna i denna rapport benämner hydrodiversitet. Forskarna har undersökt hur stor nyttan är ur ett hydrologiskt och ekonomiThis report presents our research project EcoDiver, funded by the Swedish Environmental Protection Agency. The project was conducted as a collaboration between Lund University and the Royal Institute of Technology (KTH).The main thesis has been hydrodiversity, where the diversity of hydrological units, such as wetlands, lakes, rivers and groundwater, within a catchment area interact and affect the

I denna rapport redovisas populationstrender för 224 svenska fågelarter för olika långa tidsperioder, samt korttidstrender för 13 arter av större däggdjur. Fåglarna har räknats höst, vinter, vår och sommar enligt strikt standardiserade metoder. Sommar- respektive vinterpunktrutter har räknats sedan 1975, i huvudsak i södra Sverige. Standardrutterna räknas också på sommaren (sedan 1996) men täcker We present the results of the Swedish Bird Survey, a project run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency. The results for 2023 include data from: 517 winter point counts in 2022/2023 (48th winter), of which 243 were carried out during the Christmas/New Year count, 181 summer point count routes (49t

Public sector organizations increasingly use digital platforms to foster value co-creation among diverse stakeholders and to address complex societal challenges, such as those related to sustainable development. Different kinds of digital platforms have been recognized as potential drivers of the societal transition toward a circular economy. However, little is known about the organization, govern

An accurate description of the wireless channel is essential to the development of modern wireless systems. In order to mathematically model the propagation channel, one important prior step often done is high-resolution parameter estimation. The estimation accuracy of this step has a significant impact on how well the channel models can represent reality. In this paper, we address this by improvi

Frågorna hur den allmänna repressionsnivån och enskilda straff ska se ut placeras ofta antingen hos lagstiftare eller domare. Men för att på allvar kunna diskutera frågorna och vad som är önskvärt behövs gediget underlag och en öppenhet för frågornas komplexitet och olika infallsvinklar.
