Regional eco-innovation trajectories

Given that eco-innovations and the associated renewal of regional economic structures are pivotal in addressing environmental challenges, regional research is increasingly focusing on their spatio-temporal dynamics. While green technological and industrial path developments in specific regions have received considerable attention, little effort has been made to derive general patterns of environme

A Robust Observer with Gyroscopic Bias Correction for Rotational Dynamics

We propose an observer for rotational dynamics subject to directional and gyroscopic measurements, which simultaneously estimates the gyroscopic biases and attitude rates. We show uniform almost global asymptotic and local exponential stability of the resulting error dynamics, implying robustness against bounded disturbances. This robustness is quantified with respect to a popular nonlinear comple

The role of substance use disorders in the transition from suicide attempt to suicide death : a record linkage study of a Swedish cohort

BACKGROUND: Suicidal behavior and substance use disorders (SUDs) are important public health concerns. Prior suicide attempts and SUDs are two of the most consistent predictors of suicide death, and clarifying the role of SUDs in the transition from suicide attempt to suicide death could inform prevention efforts. METHODS: We used national Swedish registry data to identify individuals born 1960-19

Quantitative assessment of cleft volume and evaluation of cleft’s impact on adjacent anatomical structures using CBCT imaging

Objectives: To determine pre-operative cleft volume and evaluate cleft´s impact on surrounding anatomical structures in children and adolescents with orofacial clefts using cone bean computed tomography (CBCT) imaging. Methods: The present retrospective study retrieved CBCT examinations of 68 patients from a previous study. The examinations had been exposed either before (n = 53) or after (n = 15)

Transporthistoriska underlag till nytta för infrastruktur och forskning : en förstudie

Rapporten är resultatet av ett tvåårigt samarbetsprojekt mellan Centrum för Näringslivshistoria och Statens maritima och transporthistoriska museer, finansierat av Trafikverkets FoI-medel. Förstudien syftar till att undersöka de väg-, civilflygs- och järnvägshistoriska samlingarnas potential som källa till historisk och annan forskning och som resurs i Trafikverkets planering och verksamhet. Målsä

Planeringsverktyg för Bus rapid Transit (BRT) i Sverige

Rapporten presenterar ett uppdaterad planeringsverktyg för Bus Rapid Transit (BRT), anpassat för en svensk kontext. Planeringsverktyget är tänkt att fungera som ett samverkansstöd för planerare och består av 25 olika parametrar fördelat på 4 olika kategorier; Stadens utformning, Kollektivtrafikens infrastruktur, Fordon och stödsystem samt Trafikering.

Empowered and engaged : Group exercise for adolescent depression – perspectives from adolescents, parents and healthcare professionals

Objectives: Depression is increasing and is a leading cause of disease burden among adolescents. Available evidence-based treatments with medication or psychotherapy have modest effects. Aerobic exercise is a hopeful alternative as an augmenter or a stand-alone treatment. Qualitative studies have shown that participants in group exercise for adolescent depression experienced improved mood and a se

Exploring the potential of rock surface luminescence from glacial sediments : dating and transport history

The dating of moraine deposits can present challenges to standard geochronological methods; terrestrial cosmogenic nuclide (TCN), sediment luminescence and radiocarbon dating may suffer from problems of incomplete resetting (by inheritance, intermittent cover/exposure, transport under unfavourable conditions) and/or a lack of suitable (organic) material. Rock surface luminescence burial dating (RS

QUANTITATIVE COARSE-GRAINING OF MARKOV CHAINS

Coarse-graining techniques play a central role in reducing the complexity of stochastic models and are typically characterized by a mapping which projects the full state of the system onto a smaller set of variables which captures the essential features of the system. Starting with a continuous-time Markov chain, in this work we propose and analyze an effective dynamics, which approximates the dyn

Tailoring the Photophysical Properties of a Homoleptic Iron(II) Tetra N-Heterocyclic Carbene Complex by Attaching an Imidazolium Group to the (CNC) Pincer Ligand─A Comparative Study

We here report the synthesis of the homoleptic iron(II) N-heterocyclic carbene (NHC) complex [Fe(miHpbmi)2](PF6)4 (miHpbmi = 4-((3-methyl-1H-imidazolium-1-yl)pyridine-2,6-diyl)bis(3-methylimidazol-2-ylidene)) and its electrochemical and photophysical properties. The introduction of the π-electron-withdrawing 3-methyl-1H-imidazol-3-ium-1-yl group into the NHC ligand framework resulted in stabilizat

Build Forward Fairer : Covid-19, Lessons Learned

The article discusses the importance of adopting a human rights-based approach in addressing the lessons learned from the Covid-19 pandemic. The article highlights the case of a human rights-based hospital in Sweden that actively reached out to vulnerable individuals in the community during the pandemic, emphasizing how the human rights-based approach contributes to building trust and thereby real

PARABOLIC RESONANCES IN THE GOSPELS AND THE QURʾĀN

There are apparent similarities between the parables contained in the Gospels and those found in the Qurʾān, which provide their audiences with illustrations of complex religious concepts and moral teachings through the imagery of everyday life. Based on the form-critical analysis of the Gospel Parable of the Sower and some Qurʾānic parables, this article aims to detect defining similarities and d

Regio- and Enantioselective Synthesis of 1,2-Diamines by Formal Hydroamination of Enamines : Scope, Mechanism, and Asymmetric Synthesis of Orthogonally Protected Bis-Piperazines as a Privileged Scaffold

We have previously reported the first formal hydroamination of enamines for the synthesis of chiral 1,2-diamines. Here, we describe: (i) the discovery, optimization, and substrate expansion of this reaction; (ii) a novel and straightforward protocol for the “click-type” synthesis of enamines in quantitative yield utilizing sodium sulfate in a dual role as an ancillary and dehydrating agent without

Intraductal papillary neoplasms of the bile ducts : a comparative study of a rare disease in Europe and Nagoya, Japan

Background: Intraductal papillary neoplasm of the bile ducts (IPNB) is a rare disease in Western countries. The aim of this study was to compare tumor characteristics, management strategies, and outcomes between Western and Eastern patients who underwent surgical resection for IPNB. Methods: A multi-institutional retrospective series of patients with IPNB undergoing surgery between January 2010 an

Temperature dependent energy transfer to Eu3+ emission centres in K5Eu(MoO4)4 crystals

Luminescence properties of a palmierite-type K5Eu(MoO4)4 crystal were studied in a wide temperature range of 7-650 K. Eu3+ ions are shown to occupy at least three non-equivalent positions in the palmierite-type structure, forming emission centres with slightly different characteristics due to an incommensurate modulated disordering. The relative intensity of the Eu3+ emission bands originating fro

Integrative species delimitation and biogeography of the Rhinella margaritifera species group (Amphibia, Anura, Bufonidae) suggest an intense diversification throughout Amazonia during the last 10 million years

The accumulation of studies delimiting species in Amazonia has not only shed light on the patterns of its outstanding species richness but also allowed a better understanding of the processes of diversification within this immense region. Nevertheless, vast knowledge gaps remain even for prominent anuran species complexes, such as the Rhinella margaritifera species group. This clade of toads compr
