An Optimization Model for the Tradeoff Between Efficiency and Equity for Mobile Stroke Unit Placement
A mobile stroke unit (MSU) is an ambulance, where stroke patients can be diagnosed and treated. Recently, placement of MSUs has been studied focusing on either maximum population coverage or equal service for all patients, termed efficiency and equity, respectively. In this study, we propose an unconstrained optimization model for the placement of MSUs, designed to introduce a tradeoff between eff
Notes on a Z′
We reexamine anomaly free U(1) extensions of the standard model in the light of LHC Drell-Yan data, constraints from unitarity, and neutrino-electron scattering to put model-independent bounds in the parameter space populated by MZ′, the Z- Z′ mixing angle (αz ), and the extra U(1) effective gauge coupling (gx′ ). We propose a formalism where any model dependence is absorbed into these three param
Structural optimisation of diffusion driven degradation processes
In this article, we propose an optimisation framework that can contribute to the prevention of premature failure or damage to building structures and can thereby strengthen their longevity. We concentrate on structures that are contaminated by chemical substances and that have strong destructive effects on the material. The aim of this contribution is a mathematical algorithm that allows the optim
Low percentage of surgeons meet the minimum recommended unicompartmental knee arthroplasty usage thresholds : Analysis of 3037 Surgeons from Three National Joint Registries
Purpose: The reported usage of UKA is around 10% in the UK, Australian and New Zealand joint registries. However, some authors recommend that a higher UKA usage of 20%, or a minimum 12 UKA cases per year, would reduce revision rates. The purpose of this study was to analyze the percentage of surgeons performing the recommended thresholds in these 3 registries. Methods: Data from the UK, Australian
Osteoporotic fractures in second-generation immigrants and Swedish natives
Summary: In this national study of osteoporotic fractures in second-generation immigrants in Sweden, we found a similar risk of osteoporotic fractures in general compared to Swedish natives, which suggests that environmental factors are important for the high risk of osteoporotic fractures in Nordic countries. Introduction: Second generation immigrants may have a similar environment as individuals
Coriolis and buoyancy effects on heat transfer in viewpoint of field synergy principle and secondary flow intensity for maximization of internal cooling
The present investigation emphases on rotation effects on internal cooling of gas turbine blades both numerically and experimentally. The primary motivation behind this work is to investigate the possibility of heat transfer enhancement by dean vortices generated by Coriolis force and U-bend with developing turbulent in the view point of the field synergy principle and secondary flow intensity ana
Clinical validity of second-generation tau PET tracers as biomarkers for Alzheimer’s disease in the context of a structured 5-phase development framework
Purpose: In 2017, the Geneva Alzheimer’s disease (AD) strategic biomarker roadmap initiative proposed a framework of the systematic validation AD biomarkers to harmonize and accelerate their development and implementation in clinical practice. Here, we use this framework to examine the translatability of the second-generation tau PET tracers into the clinical context. Methods: All available litera
Clinical validity of increased cortical binding of tau ligands of the THK family and PBB3 on PET as biomarkers for Alzheimer’s disease in the context of a structured 5-phase development framework
Purpose: The research community has focused on defining reliable biomarkers for the early detection of the pathological hallmarks of Alzheimer’s disease (AD). In 2017, the Geneva AD Biomarker Roadmap initiative adapted the framework for the systematic validation of oncological biomarkers to AD, with the aim to accelerate their development and implementation in clinical practice. The aim of this wo
Cosmetic Outcomes and Symmetry Comparison in Patients Undergoing Bilateral Therapeutic Mammoplasty for Breast Cancer
Background: Breast-reduction techniques are increasingly used in oncoplastic breast surgery. Bilateral therapeutic mammoplasty has the benefit of decreasing breast volume, enabling resection of larger tumors, and the potential to assure good postoperative symmetry. The aims of this study were to objectively asses the cosmetic outcomes of therapeutic mammoplasty in patients with breast cancer, usin
Structured light sheet microscopy for high contrast 3D imaging of whole mouse brain
Tissue clearing allows 3D-imaging of large biomedical samples, but can be affected by blur effects limiting individual cells detection. Using a structured illumination light sheet we solve this issue, obtaining high-contrast images in turbid samples.
Aquaporin-1 in breast cancer
The canonical function of aquaporin (AQP) water channels is to facilitate passive transport of water across cellular membranes making them essential in the regulation of body water homeostasis. Moreover, AQPs, including AQP1, have been found to be overexpressed in multiple cancer types, including breast cancer, where AQP1 overexpression is associated with poor prognosis. AQPs have been shown to af
Fetal posterior cerebral artery configurations in an ischemic stroke versus an unselected hospital population
Background: Few MRA-based studies have systematically evaluated the prevalence and laterality of a fetal configuration of the posterior cerebral artery (FTP) in ischemic stroke populations versus other populations. This common variant is important in the setting of acute stroke and secondary prevention decisions. Objective: To determine the prevalence and laterality of FTP configurations in MRI-DW

Predicted and user perceived heat strain using the ClimApp mobile tool for individualized alert and advice
Thermal models and indices integrated into a mobile application could provide relevant information regarding thermal stress and strain to the general public. The aim of the current paper is to validate such a mobile application, ClimApp, to the users needs in the heat. ClimApp combines weather data with personal user data, thermal models and indices to estimate the thermal strain of the user. The
Short-term outcomes following beyond total mesorectal excision and reconstruction using myocutaneous flaps : A retrospective cohort study
Introduction: Beyond total mesorectal excision (bTME) offers long-term survival in patients with advanced pelvic malignancy. At Skåne University Hospital (SUS) Malmö in Sweden, the vertical rectus abdominis musculocutaneous (VRAM) and gluteal maximus (GM) flap have been used for perineal reconstruction to promote healing and functional outcomes after significant tissue loss. This study aims to exa
The use of multi-zone modelling for tunnel fire risk analysis
Tunnel fire risk analysis are a useful tool to ensure adequate safety levels in tunnels. This report presents the work conducted to integrate a multi-zone modelling approach into a fire risk assessment tool, called ARTU. This work was performed to improve its fire modelling predictive capabilities compared to the currently adopted 1D fire modelling representation. This is deemed to allow for the u
Historical precedents and feasibility of rapid coal and gas decline required for the 1.5°C target
To limit global warming to 1.5°C, fossil fuel use must rapidly decline, but historical precedents for such large-scale transitions are lacking. Here we identify 147 historical episodes and policy pledges of fossil fuel decline in 105 countries and global regions between 1960 and 2018. We analyze 43 cases in larger systems most relevant to climate scenarios. One-half of 1.5°C-compatible scenarios e
