Pathways to Urban Sustainability : How Science Can Contribute to Sustainable Development in Cities

Pressing sustainability challenges reinvigorate calls for scientific actors to strengthen their profile as change agents. Focusing on the urban context, we point to four forms of science-policy-society interactions as key pathways to advance the sustainability transformation in cities.Recent years have seen a considerable broadening of the ambitions in urban sustainability policy-making. With its

Exploring alternative economic pathways : a comparison of foundational economy and Doughnut economics

A number of intersecting crises are currently ongoing at multiple scales, including increasing inequality, environmental degradation, and climate destabilization, as well as new surges of populism and mounting public health threats. These emergencies question our economic model of past decades and provoke a rethinking of the general approach to economic policy from a multi-scalar perspective. In t

The development of the experience curve concept and its application in energy policy assessment

This paper presents some of the results of the project, EXTOOL, Experience Curves: A Tool for Energy Policy Programmes Assessment, funded by the European Commission. The objective of the project was to analyse the experience curve as a tool for the assessment of energy policy measures. This is of special interest, since the use of experience curves for the assessment of energy policy measures requ

A plant-wide model describing GHG emissions and nutrient recovery options for water resource recovery facilities

In this study, a plant-wide model describing the fate of C, N and P compounds, upgraded to account for (on-site/off-site) greenhouse gas (GHG) emissions, was implemented within the International Water Association (IWA) Benchmarking Simulation Model No. 2 (BSM2) framework. The proposed approach includes the main biological N2O production pathways and mechanistically describes CO2 (biogenic/non-biog

A theoretical framework for addressing fear of falling avoidance behavior in Parkinson’s disease

Postural instability in Parkinson’s disease (PD) is associated with several downstream consequences that ultimately lead to a greater risk of falling. Among the prominent downstream consequences is fear of falling (FOF), which is both common and problematic in PD. It can lead to a vicious cycle of FOF avoidance behavior that results in more sedentary behavior, physical deconditioning, and weakenin

Ultrafast dynamics of hot charge carriers in an oxide semiconductor probed by femtosecond spectroscopic ellipsometry

Many linked processes occur concurrently in strongly excited semiconductors, such as interband and intraband absorption, scattering of electrons and holes by the heated lattice, Pauli blocking, bandgap renormalization and the formation of Mahan excitons. In this work, we disentangle their dynamics and contributions to the optical response of a ZnO thin film. Using broadband pump-probe ellipsometry

Electronic transitions and dielectric function tensor of a YMnO3 single crystal in the NIR-VUV spectral range

We present optical properties in the near-infrared to vacuum-ultraviolet spectral range of hexagonal YMnO3. The high-quality (110)-oriented bulk single crystal was grown by the optical floating zone technique. We have determined the tensor of the dielectric function by means of Mueller matrix ellipsometry in the wide spectral range (0.5-9.15) eV. For the spectral range below 5.4 eV, we present muc

Development of optical diagnostics of plasma-related phenomena and applications

Optical diagnostics techniques based on coded imaging were developed and applied for plasma-related phenomena and applications. The signal of interest is first encoded with a sinusoid pattern either by structured laser illumination or implement of a diffractive optical element, such as a grating, along the optical path of the signal. The coded signal will then be extracted from the raw data by a l

Multimodality treatment of 128 patients with locally advanced breast carcinoma in the era of mammography screening using standard polychemotherapy with 5-fluorouracil, epirubicin, and cyclophosphamide : prognostic and therapeutic implications

BACKGROUND: Locally advanced breast carcinoma is associated with a poor prognosis. With single treatment modalities, i.e., surgery and/or radiation therapy, results have been consistently dismal. However, several earlier reports have indicated improvement in survival with a combined modality approach, i.e., the utilization of systemic therapy.METHODS: Between 1991 and 1994, 128 patients with local

Psychological profile related to malignant tumours of different histopathology

In a previous preoperative study of patients with gliomas, we made the original observation that patients with high grade as opposed to those with low-grade gliomas have a psychological profile marked by extreme emotional reactivity. In this postoperative study of the psychological profiles of patients with breast cancer, the main funding was unexpectedly analogous with the findings in the brain t

Clinical experience of tensor-valued diffusion encoding for microstructure imaging by diffusional variance decomposition in patients with breast cancer

Background: Diffusion-weighted imaging plays a key role in magnetic resonance imaging (MRI) of breast tumors. However, it remains unclear how to interpret single diffusion encoding with respect to its link with tissue microstructure. The purpose of this retrospective cross-sectional study was to use tensor-valued diffusion encoding to investigate the underlying microstructure of invasive ductal ca

Quantifying the Steric Effect on Metal-Ligand Bonding in Fe Carbene Photosensitizers with Fe 2p3d Resonant Inelastic X-ray Scattering

Understanding the electronic structure and chemical bonding of transition metal complexes is important for improving the function of molecular photosensitizers and catalysts. We have utilized X-ray absorption spectroscopy (XAS) and resonant inelastic X-ray scattering (RIXS) at the Fe L3 edge to investigate the electronic structure of two Fe N-heterocyclic carbene complexes with similar chemical st

Sharing Communities: An Alternative Post-Pandemic Residential Logic

Sweden needs affordable housing solutions to counteract segregation and isolation whilst promoting resilient cities. The COVID-19 pandemic has changed the conditions for being and sharing with others. The aim of the article is to explore residents practices of inhabiting, sharing and being involved in existing collaborative housing during the pandemic. The article conceptualizes collaborative hous

Computational Fluid Dynamics Support for Fontan Planning in Minutes, Not Hours : The Next Step in Clinical Pre-Interventional Simulations

Computational fluid dynamics (CFD) modeling may aid in planning of invasive interventions in Fontan patients. Clinical application of current CFD techniques is however limited by complexity and long computation times. Therefore, we validated a "lean" CFD method to magnetic resonance imaging (MRI) and an "established" CFD method, ultimately aiming to reduce complexity to enable predictive CFD durin

Sustainable Development and Canada’s Transitioning Energy Systems

An energy transition is unfolding in Canada and across the world. During this transition, countries are facing increasing demands for their energy systems to address economic, social, and environmental considerations, including providing affordable and reliable energy, reducing inequality, and producing fewer environmental impacts. First, we identify key themes from the academic literature related

Balancing innovation, ‘ordre public’ and morality in human germline editing : A call for more nuanced approaches in patent law

This article analyses the role that ‘ordre public’ and morality exceptions can play in the granting of patents on inventions in the field of human germline editing and the consequences of this policy option. In order to provide the context for such an analysis, the article will, first, provide an overview of the current patent landscape for relevant genome editing technologies, drawing attention t
