Studying individual trees is a common way that scientists employ to study forests and estimate forest parameters. In this study, a graph-based approach was developed for detecting individual trees in a broadleaf, complex forest region based on UAV-derived point cloud data. Horizontal cross-sections at different heights were applied to the Canopy Height Model (CHM) to extract initial candidates for

The visual environment provides vital cues allowing animals to assess habitat quality, weather conditions or measure time of day. Together with other sensory cues and physiological conditions, the visual environment sets behavioral states that make the animal more prone to engage in some behaviors, and less in others. This master-control of behavior serves a fundamental and essential role in deter

Modeling of combustion engines using computational fluid dynamics (CFD), to investigate and improve performance of biodiesel combustion, calls for development of small and efficient chemical kinetics mechanisms that accurately represent ignition and flame propagation of renewable fuels. In this work, a semi-global approach is used to develop a mechanism suitable for three-dimensional CFD of fatty

Alongside established heritage institutions, family historians are central figures in the ecosystem of digital heritage, both as contributors to and users of digitized historical sources. With that in mind, this research aims for a wide examination of family historians’ engagement with the broader selection of available digital platforms, providing knowledge about how and why they choose to use on

BACKGROUND: Swedish policy states that older adults should be able to age safely with continued independence and lead active lives. However, this plays out differently in different Swedish municipalities depending upon degree of demographic change, globalization, and urbanization. Internationally, older adults living in disadvantaged areas have worse physical and mental health, activity restrictio

We introduce the concept of subalgebra spectrum, Sp(A), for a subalgebra A of finite codimension in K[x]. The spectrum is a finite subset of the underlying field. We also introduce a tool, the characteristic polynomial of A, which has the spectrum as its set of zeroes. The characteristic polynomial can be computed from the generators of A, thus allowing us to find the spectrum of an algebra given

The present study examined the thoughts and feelings of solo mothers by choice (SMC) regarding their experiences during pregnancy and early parenthood, with special focus on their contact with maternal health-services (MCHS). Semi-structured interviews were carried out with solo mothers (N = 10) who had undergone assisted fertilization in Sweden. Thematic analysis revealed two main themes. The fir

Objectives: To assess the prevalence of reported and unreported incidental pulmonary embolism (iPE) in patients with cancer, and to evaluate an artificial intelligence (AI) algorithm for automatic detection of iPE. Methods: Retrospective cohort study on patients with cancer with an elective CT study including the chest between 2018-07-01 and 2019-06-30. All study reports and images were reviewed t

BACKGROUND AND OBJECTIVES: Dementia cases are expected to triple during the next 30 years, highlighting the importance of finding modifiable risk factors for dementia. The aim of this study is to investigate whether adherence to conventional dietary recommendations or to a modified Mediterranean diet are associated with subsequent lower risk of developing all-cause dementia, Alzheimer's disease (A

BACKGROUND: Lead exposure has been associated with increased incidence of adverse clinical cardiovascular outcomes. Atherosclerosis has been suggested as one of the underlying mechanisms, and findings from experimental studies support this, but human data are scarce. OBJECTIVES: Our objective was to determine the association between environmental lead exposure based on blood lead (B-Pb) concentrat

This study focuses on communication and conceptions of obstetric care to address the postulates that immigrant women experience sensitive care through the use of an ethnically congruent interpreter and that such women prefer to meet health providers of the same ethnic and gender profile when in a multiethnic obstetrics care setting. During 2005-2006, we conducted in-depth interviews in Greater Lon

5G cellular networks can utilize millimeter wave signals, and support large bandwidths and large antenna arrays, which provide more geometric-based signals and higher delay and angle resolutions. These merits bring new opportunities in positioning the user with limited infrastructure through the use of combined angle and delay information. However, there are many practical challenges to overcome,

Background: The instant, single-sampling rule-out of acute myocardial infarction (AMI) is still an unmet clinical need. We aimed at testing and comparing diagnostic performance and prognostic value of two different single-sampling biomarker strategies for the instant rule-out of AMI. Methods: From the Biomarkers in Acute Cardiac Care (BACC) cohort, we recruited consecutive patients with acute ches

Digitalisering och förtroende är två fenomen som är intimt sammankopplade i offentliga organisationers interna och externa kommunikation. I denna rapport diskuteras på vilket sätt digitaliseringen av den svenska offentliga sektorn är cen-tral både för medborgarnas förtroende och tillit till myndigheter i en alltmer kommunikativt komplex värld, och för medarbetarnas förtroende och tillit till sina

Vi studerar stjärnors rörelser i Vintergatan med N-body simuleringar och stora astrometriska dataset från ESAs rymdteleskop Gaia. Vi identifierar två kinematiska populationer för vita dvärgar i Solens kvarter. Vi undersöker även ansamlade halon och avslöjar två nya hastighetsstrukturer. Slutligen, våra simuleringar visar att radiell migrering som en funktion av vertical action beror på diskmassa.We study stellar motions in the Milky Way with N-body simulations and large astrometric samples from ESA's Gaia mission. We identify two kinematic populations for white dwarfs in the Solar neighbourhood. We also investigate the accreted halo and reveal two new structures. Finally, our simulations show that radial migration as a function of vertical action depends on disc mass.

Based on interviews with three generations of professors reflecting upon their development as early career researchers in an outstanding research environment within the STEMfield, this study aimed to explore how they had coped with relationship conflicts in the environment, how this had an impact on their team socialisation, and how their development was framed by their supervisors’ leadership. Us

Phase contrast micro-CT is a powerful technique allowing imaging of soft tissue at synchrotrons or using lab- oratory sources. The use of contrast agents is a useful approach when imaging vascular structures. However, common x-ray contrast agents typically rely on heavy metals to increase absorption, which may affect the phase contrast and cause artifacts in the reconstructed volumes. Thus, utiliz
