Eye and wing structure closely reflects the visual ecology of dung beetles

An important resource partitioning strategy allowing dung beetles to coexist in the same habitat, while utilising the same food, is species’ separation of activity times. After establishing the diel activity period of three closely related, co-occurring dung beetles, we examined their eye and wing morphology. Absolute and relative eye size, and facet size were greater in the nocturnal Escarabaeus

Repeatability and reproducibility of longitudinal relaxation rate in 12 small-animal MRI systems

Background: Many translational MR biomarkers derive from measurements of the water proton longitudinal relaxation rate R 1 , but evidence for between-site reproducibility of R 1 in small-animal MRI is lacking. Objective: To assess R 1 repeatability and multi-site reproducibility in phantoms for preclinical MRI. Methods: R 1 was measured by saturation recovery in 2% agarose phantoms with five

Perioperative management of radical cystectomy in the Nordic countries

Objective: Radical cystectomy is performed in all of the Nordic countries, but the current practice patterns remain unclear. This study explored current perioperative care and adherence to the Early Recovery After Cystectomy (ERAC) protocol and EAU guidelines by cystectomy surgeons in the Nordic countries. Materials and methods: The study was performed as a survey including 47 centers performing c

Marital status and 5-year mortality : A population-based prospective cohort study

Objectives: The aim was to investigate the association between baseline marital status and mortality using survival (Cox-regression) analysis. Study design: This is a prospective cohort study. Methods: The public health survey by Scania in 2008 was linked to the Swedish cause of death register. This prospective cohort study includes 12,245 men and 14,969 women aged 18–80 years, and 538 men and 362

Observer Backstepping and Control Design of Linear Systems

We show that the observer-backstepping technique applied to linear control object and combined with linear control system design gives rise to a non-standard composition of control object, observer and controller. The resultant system is characterized by a full-order observer and a reduced-order control system design which in its complexity does not go beyond the `relative degree' of the control o

Early withdrawal of life support after resuscitation from cardiac arrest is common and may result in additional deaths

Aim: “Early” withdrawal of life support therapies (eWLST) within the first 3 calendar days after resuscitation from cardiac arrest (CA) is discouraged. We evaluated a prospective multicenter registry of patients admitted to hospitals after resuscitation from CA to determine predictors of eWLST and estimate its impact on outcomes. Methods: CA survivors enrolled from 2012–2017 in the International C

Target definition in radiotherapy of prostate cancer using magnetic resonance imaging only workflow

In magnetic resonance (MR) only radiotherapy, the target delineation needs to be performed without computed tomography (CT). We investigated in thirteenpatients with prostate cancer, how the clinical target volume (CTV) was affected, when the target delineation procedure was changed from using both CT and MRimages to using MR images only. The mean volume of the CTVCT/MR was 61.0 cm3 as compared to

Promoting eco-innovation in academic eco-systems

University incubators are an opportunity to promote the dissemination of research, change teaching practices and contribute to territorial economic development. In this article we present a structural and dynamic analysis of such an innovation system of a Swedish eco-innovation system by proposing elements for analysing the success of such innovation systems.
