Making use of the APOGEE DR17 catalogue with high quality data for 143 509 red giant branch stars we explore the strength of different mechanisms that causes a star to radially migrate in the Milky Way stellar disc. At any position in the disc we find stars that are more metal-rich than the local interstellar medium. This is surprising and normally attributed to the migration of these stars after
We study the realizability and strong satisfiability problems for SAFETY LTL, a syntactic fragment of Linear Temporal Logic ([Formula presented]) capturing safe formulas. While it is well-known that realizability for this fragment lies in [Formula presented], the best-known lower bound is [Formula presented]-hardness. Surprisingly, closing this gap has proven an elusive task. Previous works have c
This paper addresses attitude synchronization problems for systems of multiple rigid-body agents with directed interconnection topologies. Two scenarios which differ in available information are considered. In the first scenario the agents can obtain their rotations and angular velocities relative to an inertial reference frame and transmit these information to their neighbors, while in the second
In this paper we consider the problem of constructing feedback control laws for a system of n agents that shall synchronize their attitudes in SO(3). We propose distributed controllers for two synchronization problems, in which the objective is the same, to synchronize the orientations, but what the agents can perceive or communicate differs. In the first problem the agents can measure their orien
False Discovery Rate (FDR) and the Bayes risk are two different statistical measures, which can be used to evaluate and compare multiple testing procedures. Recent results show that under sparsity FDR controlling procedures, like the popular Benjamini-Hochberg (BH) procedure, perform also very well in terms of the Bayes risk. In particular asymptotic Bayes optimality under sparsity (ABOS) of BH wa
This paper examines how the significant events and team member trust in new ventures affect exit from the team. We consider team member exit as an outcome that affects both individuals, the team, and the performance of the new venture. We develop our arguments based on event system theory, which is specifically beneficial to understand how new ventures develop. We test our arguments using a unique

Immunoglobulin G4-related disease (IgG4-RD), which was initially identified as a type of autoimmune pancreatitis around the year 2000, is now widely acknowledged to be a systemic sickness. Based on both general and organ-specific criteria, alongside laboratory measurements of IgG4-subtype, the diagnosis is made. The diagnosis requires, however, a heightened index of suspicion, especially given the
Aims: Iron deficiency (ID) is comorbid in up to 50% patients with heart failure (HF) and exacerbates disease burden. Ferric carboxymaltose (FCM) reduced HF hospitalizations and improved quality of life when used to treat ID at discharge in patients hospitalized for acute HF with left ventricular ejection fraction <50% in the AFFIRM-AHF trial. We quantified the effect of FCM on burden of disease an
Rural communities tell us the story of a thousand of years of collaboration between nature, culture and humans. The current Covid-19 pandemic is considerably threating rural areas, posing challenges exacerbated by low available financial resources, not easily accessible health services and greater isolation. Rural areas are also considered safe shelters characterized by better daily living conditi
Allowing for free choice of the recipient's gender in a dictator game (N=357), women give more frequently to their own gender (70.3% vs 9.4%) while men do not prefer a specific recipient's gender (33.3% vs 27.8%). Conditional on a positive transfer being made, the average amount of transfers to each gender does not vary between genders, though. Once a charity recipient is added to the possible cho
We challenge the obvious and easy association of enterprise and entrepreneurship. We do so by arguing that entrepreneurship is inherently social and collective, something that is concealed when held up as example of enterprising behaviour. We use as an illustrative case the Chinese artist Ai Weiwei, an example of entrepreneurship that has little to do with commerce and everything to do with the so
This article explores new forms of organizing (and organization creation) in relation to entrepreneurship and social transformation. In particular, in the dialogue that follows in this issue, we initiate a discussion regarding the ways through which social transformation is or can be related to community action and public and/or social entrepreneurship. By focusing on socioeconomic environments in
In this work, we present a method for acquiring, storing, and using scene data to enable realistic shading of virtual objects in an augmented reality application. Our method allows for sparse sampling of the environment’s lighting condition while still delivering a convincing shading to the rendered objects. We use common camera parameters, provided by a head-mounted camera, to get lighting inform
The Nobel Prize in Literature to the Austrian writer Peter Handke in 2019 gave new attention to one of the basic, and historically highly disputed (cf. Espmark 2001, 2021), questions in relation to the practice of the world’s most important literary prize – on what grounds, aesthetic or otherwise, does the Swedish Academy award the prize? In the aftermath of the 2019 prize to Handke, there was an
