Despite their simplicity, networks of coupled phase oscillators can give rise to intriguing collective dynamical phenomena. However, the symmetries of globally and identically coupled identical units do not allow solutions where distinct oscillators are frequency-unlocked - a necessary condition for the emergence of chimeras. Thus, forced symmetry breaking is necessary to observe chimera-type solu
Thomas Mathiesen’s theories, his activism and his scholarship are needed, important and useful for contemporary researchers concerned with social change and social justice. At this moment in time, when strong social movements and abolitionism are back on the agenda, Mathiesen’s theories can not only be revitalised, but moved forward in the everlasting unfinished fashion. Mathiesen’s work might be
The effects of myoglobin on renal microcirculation were studied in anesthetized rats subjected to hemorrhagic hypotension. Capillary flow distribution was determined by allowing two dyes to circulate for 3 and 1 min, respectively, freezing the left kidney and quantifying the dye distribution in histological sections by analyzing the distances of regularly spaced test points to the next dye-labeled
This paper aims to discuss polycentrism and its implications. Polycentricity plays a key role in EU Cohesion Policy and has done so since 1999 when the notion was included in the European Spatial Development Perspective. Politically, it emerged as a key tool because of its ability to fuse together the two primary and conflicting perceptions of spatial–economic development, cohesion and competitive
We present morphological and molecular evidence of the occurrence of hybrids between great reed warblers Acrocephalus arundinaceus and clamorous reed warblers A. stentoreus in Kazakhstan where both species breed. Three males and one female of 249 examined individuals had wing characteristics that were intermediate between the parental species. Molecular analyses of a nuclear microsatellite locus a
In this study, a dilute mixture of volatile organic compounds in aqueous solution was separated by means of hydrophobic pervaporation, using three different poly(octylmethyl siloxane) membranes of various thicknesses. The permeabilities were determined for homologous series of compounds from the chemical groups of alcohols, esters, and aldehydes, and they were then related to some characteristic p
Aim: To identify maternal prenatal and postnatal smoking as risk factors for psychosocial behaviour problems in Swedish preschool children. Methods: This prospective, longitudinal population study compared mothers' self-reported smoking during pregnancy and when the child was 3 mo old with behaviour problems according to Achenbach's Child Behavior Checklist at 3 y ( 1428 children) and 5.5 y of age
While there is growing awareness of the importance of gender issues in medicine, with new knowledge and new perspectives inmedical curricula are scarce. In 1996, the Medical Faculty of Goteborg University, Sweden, determined that a gender-issues perspective be included in medical education. In 1999, course organizers from preclinical and clinical departments of the faculty were interviewed to dete
Indices of mineral metabolism in blood and urine were analysed in relation to blood pressure in 97 healthy subjects aged 16-82 years. In a multivariate analysis, after allowing for the effects of sex, body mass index (BMI) and age, there was an inverse relationship between plasma level of ionized calcium and mean blood pressure (MBP) (beta = -50.0 mmHg/mmol/l P-ionized calcium, p = 0.0005). In uni
Viewing information systems (IS) as services is beneficial but still an unexplored approach for IS in organizations. The aim of this exercise is to contribute to the knowledge base on designing IS as services. This paper presents an analysis of enterprise resource planning (ERPs) systems through the lens of service oriented architecture (SOA). Services are explained and defined through SOA theory.
Construction projects are costing too much and taking too long as a consequence of unnecessary omissions and errors in project documentation and sub-optimal coordination of design information between consultant disciplines. The theory behind BIM provides an exciting integrated solution for project information management, however in this new process further effort is required to define the content
The aim was to develop a short version of the Swedish Process of Recovery Questionnaire (QPR-Swe) for use with people with severe mental illness and to investigate its internal consistency, construct validity, known-groups validity and any floor or ceiling effects. Two independent samples were used, the first (N = 226) to develop the short version and the second (N = 266) to test its psychometric
High-resolution paired analyses of δ13Ccarb and δ13Corg from a new drill core from Gotland, Sweden, demonstrate asynchronous positive change in the carbon isotope records during the onset of one of the major Silurian biogeochemical events known as the Mulde Event or “Big Crisis”. The detailed carbon isotope record presented here provides Δ13C (the difference between δ13Ccarb and δ13Corg) and allow
Drug-related problems in the elderly is intended to serve as a source of information and clinical support in geriatric pharmacotherapy for students as well as all health care professionals, e.g. physicians, nurses and pharmacists. Pharmacotherapy is of great importance to all mankind. Drugs are however powerful and must be handled appropriately. This is especially important for elderly patients. D
Sustainable finance, non-financial disclosures, ESG, oh my! The world of sustainable finance may seem dark and scary. But, in this episode, we introduce many key concepts through dialogue as well as discuss how sustainable finance contributes to wider sustainability objectives. The finance sector is playing an ever growing role in supporting the transition to a Paris-aligned world by incorporating
We suggest two methods for simulating from a multivariate copula in an arbitrary dimension. Although our main emphasis in this paper is on multivariate extreme value distributions, the proposed methods can be applied to any copula. The basic idea is to approximate the (unknown) density of the copula by a distribution that has a piece‐wise constant (histogram) density. This is achieved by partition
Insect olfactory receptors are routinely expressed in heterologous systems for functionalcharacterisation. It was recently discovered that the essential olfactory receptor co-receptor (Orco)of the Hessian fly, Mayetiola destructor (Mdes), does not respond to the agonist VUAA1, whichactivates Orco in all other insects analysed to date. Here, using a mutagenesis-based approach weidentified three res
The idea that excitonic (electronic) coherences are of fundamental importance to natural photosynthesis gained popularity when slowly dephasing quantum beats (QBs) were observed in the two-dimensional electronic spectra of the Fenna–Matthews–Olson (FMO) complex at 77 K. These were assigned to superpositions of excitonic states, a controversial interpretation, as the strong chromophore–environment
Aridity and seasonality of precipitation are characteristics of the highland region in Bolivia. Groundwater becomes an important and safe source of water when surficial bodies are intermittent and affected by natural and anthropogenic contamination. Decades of exploitation of the Challapampa aquifer, combined with lack of information required to understand the groundwater circulation, represent a
