This paper addresses the problem of consensus on SO(3) for networks of uncalibrated cameras. Under the assumption of a pinhole camera model, we prove convergence to the consensus manifold for two types of kinematic control laws, when only conjugate rotation matrices KRK -1 are available among the agents. In these conjugate rotations, the rotation matrices are distorted by the (unknown) intrinsic p

Businesses across different areas of interest are increasingly depending on data, particularly for machine learning (ML) applications. To ensure data provisioning, inter-organizational data sharing is proposed, e.g. in the form of data ecosystems. The aim of this study was to perform an exploratory investigation into the data sharing practices that exist in business-to-business (B2B) and business-

Recent self-reported and cross-sectional survey evidence documents high levels of mental health problems among PhD students. We study the impact of PhD studies on mental health care uptake using Swedish administrative records of prescriptions for psychiatric medication for the full population of PhD students. First, we provide descriptive evidence that PhD students collect psychiatric medication a

Understanding how momentum anisotropies arise in small collision systems is important for a quantitative understanding of collectivity in terms of QCD dynamics in small and large collision systems. In this letter we present results for small collision systems from the newly developed parton cascade ALPACA, which faithfully encodes the AMY effective kinetic theory. ALPACA reproduces quantitatively

Economic research on gender gaps in preferences and economic outcomes has focused on variation with respect to sex—a binary classification as either a “man”or “woman.” We validate a novel and simple measure of self-reported continuousgender identity (CGI) and explore whether gender identity correlates with variationin economic decisions and outcomes beyond the relationship with binary sex.We use f

Identifying key molecular pathways and genes involved in the response to urban pollutants is an important step in furthering our understanding of the impact of urbanisation on wildlife. The expansion of urban habitats and the associated human-introduced environmental changes are considered a global threat to the health and persistence of humans and wildlife. The present study experimentally invest

Objectives: To examine the risk of fractures in a cohort of patients with newly diagnosed rheumatoid arthritis (RA), compared to the background population, and predictors of fractures detectable early in RA. Methods: An inception cohort of patients with RA (N = 233; 164 women/69 men, recruited 1995–2005) was evaluated according to a structured program, including repeated clinical assessments and m

This paper is a study of the implementations of two new working methods, systems construction and incentive contracts, in Swedish State building construction around 1970 with an analysis of the implication of such implementations on the organization of the building industry. Specifically, the study is focusing on the role of the architect in the building process of the National Board of Public Bui

Significant progress has been made in elucidating genetic risk factors influencing Type 1 diabetes (T1D); however, features other than genetic variants that initiate and/or accelerate islet autoimmunity that lead to the development of clinical T1D remain largely unknown. We hypothesized that genetic and environmental risk factors can both contribute to T1D through dynamic alterations of molecular

Both straight and curved carbon fibers are widely used in various commercial gas diffusion layer (GDL) fabrications. The effect of the different carbon fiber curvatures on two-phase flow dynamics within the cathode GDLs of proton exchange membrane fuel cells remains unclear. In this study, we investigate liquid transport in three types of GDLs with varying fiber curvatures using the two-phase volu

The production, reading and correcting of article proofs is a highly important part of scholarly publishing, and the proof of an article is the only place where researcher, journal production team and publisher come together, directly or indirectly. Yet, the proof process is rarely examined or discussed, and scholars seem to regard it as something separated from the research process. This paper waThe production, reading, and correcting of article proofs is a highly important part of scholarly publishing, and the proof of an article is the only place where researcher, journal production team, and publisher come together, directly or indirectly.

When coupled to different applications, a polymer electrolyte fuel cell (PEFC) work at a different operating temperature. In this study, the internal resistance of a PEFC is evaluated by using Electrochemical Impedance Spectroscopy (EIS) at moderate low current density, i.e., 0.5 A/cm2, in the range of 40 – 80°C. The evaluation is carried out considering frequencies between 10kHz and 0.1Hz. An equ

A large body of scholarly work has been dedicated to the Swedish reduction in the early 1680s, when fiefs granted to the nobility were revoked as the crown strengthened its position. However, this research has focused on political and economic developments with an elite perspective. Insufficient attention has been paid to the actions and lived reality of other groups, not least the servants of the

Artikeln behandlar hur bomärken brukades av bönder i byn Väby i Bräkne-Hoby socken i Blekinge från 1600-talets slut till 1800-talets första hälft. Dessutom analyseras utvecklingen då bomärkena som underskrifter successivt ersattes med initialer. Först tecknas en översiktlig bild av bomärkenas långa historia och deras roll i den svenska allmogekulturen. Därefter presenteras byn Väby och de förhålla
