Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen-containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and mammals. In this review, we focus on the role of pyrazine
BACKGROUND: Familial aggregation of stroke is well-documented, yet few studies have examined associations between stroke subtypes-particularly early-onset cryptogenic ischaemic stroke (eCIS)-and broader family history (FH) of cardiovascular disease. Such associations may provide insights into underlying etiologic mechanisms. METHODS: In this multicentre case-control study, we included eCIS patient
We address discrete-time consensus on the Euclidean unit sphere. For this purpose we consider a distributed algorithm comprising the iterative projection of a conical combination of neighboring states. Neighborhoods are represented by a strongly connected directed graph, and the conical combinations are represented by a (non-negative) weight matrix with a zero structure corresponding to the graph.
Denna avhandling undersöker hur aktörer i Stilla havet producerade och spred oppositionell kunskap om kärnvapentester från 1950-talet till början av 2000-talet, med Franska Polynesien i fokus. För att analysera detta lanseras begreppet vittnesaktivism som övergripande står för organiserade praktiker av vittnesmål, dokumentinsamling, arkivering och transnationell spridning, genom vilka aktörer utmaThis dissertation examines how actors in the Pacific produced, mobilized, and circulated oppositional knowledge about nuclear weapons testing from the 1950s to the early 2000s, with French Polynesia as its primary focus. At its core is witness activism: coordinated practices of testimony, document retrieval and annotation, archiving, publication, and transnational circulation through which activis
INTRODUCTION: People with longstanding hip and groin pain (LHGP) are often referred to orthopaedic care. Physical therapist-led interventions are recommended in consensus statements as the first line of treatment, but it is unknown if structured interventions are more effective than usual care. The aim of this trial is to evaluate the effectiveness of a structured physical therapist-led treatment
Relaxed eddy accumulation (REA) measurements for 14CO2 enable the estimation of fossil fuel (ff) CO2 fluxes in urban areas. This work is based on 252 REA ffCO2 flux measurements conducted on tall towers in the cities of Zurich, Paris, and Munich. The ffCO2 fluxes were compared to net eddy covariance CO2 fluxes to quantify the role of non-fossil (nf) CO2 fluxes. While the measurements in Zurich and
This thesis consists of three essays in dynamic panel data econometrics. It studies the estimation of persistent dynamic relationships in panel models with unobserved heterogeneity and predetermined regressors, combining methodological contributions with an application in growth empirics.The first paper analyzes structural breaks in persistence in a dynamic panel first-order autoregressive model w
This instruction is for the bioFDM printing process developed at bioDigital matter lab. It was developed for the production of Protomycokion, a 2 m tall experimental column. The recipe uses a wood-decomposing brown-rot fungus, Gloeophyllum, and results in lightweight objects with a hard, brownish and variable surface. The resulting surface is hydrophobic yet allows water vapor permeability.
Democratic argument is not failing for lack of logic. It is failing because the shared ground beneath logic – the premises citizens once held in common – has fractured under information environments engineered for engagement rather than truth. When the same evidence is anchored by incompatible starting points, argument cannot cross; communities harden into fortresses built not from facts, but from
The structure and function of many proteins are regulated post-translationally through glycan attachment. These glycans, assembled via competing enzymatic reactions, generate diverse glycoform populations - variants sharing a protein backbone but differing in glycan structures. While current analyses often focus on individual glycoforms, we demonstrate that population-level glycoform analysis - in
Antibiotic persistence is a phenomenon, where a small fraction of a bacterial population expresses a phenotypic variation that allows them to survive antibiotic treatment, which is lethal to the rest of the population. These cells are called persisters cells, and their occurrence has been associated with recurrent disease. Streptococcus agalactiae is a human pathobiont, able to cause invasive infe
Since the 1980s, financial deregulation and welfare cuts have driven an economic risk shift, requiring individuals to take greater financial responsibility through private savings in stocks and mutual funds. An unexplored aspect of this “financialization of everyday life” is the personal finance advice provided by experts employed by banks and other market-oriented actors. This study examines fina
This thesis examines how the wealthiest apex of the capitalist class, a segment commonly referred to as ‘the super-rich’, is represented in Swedish legacy newspapers. As decades of neoliberal reforms have paved the way for increasing wealth concentration at the very top, the super-rich has emerged as both a material and discursive phenomenon. The news media provides an influential site for studyin
The Amazon is rapidly approaching an ecological tipping point driven by deforestation, forest degradation and global climate change. These are visible issues that receive increasing political and public attention.However, the accelerating biocultural loss in the Amazon, including the extinction of Indigenous languages, the disruption of Indigenous and local knowledge systems, and the disintegratio
Indigenous and Local Knowledge (ILK) is an expression of biocultural diversity and is vital for inclusive and sustainable forest management and epistemic justice. We examine how researchers studying tropical forest fauna engage with ILK and the Indigenous Peoples and Local Communities (IPLC) who are holders of this knowledge. We conducted a systematic review of 62 articles that focus on tropical f
