Investigation of flame characteristics and cooling effectiveness of jet-cooled wall flameholders in vitiated flow

Experimental and numerical studies were performed to understand the flame characteristics and cooling effect of jet-cooled wall flameholders in a simplified augmented combustor. The time-averaged flame structure and wall temperature were investigated employing an instantaneous flame capturing system with image processing technology and a wall temperature measurement system, respectively. Flow and

Non-monotone cellular automata : Order prevails over chaos

We consider a model for the propagation of electrical impulses or activity in a neuronal network. The vertices of a square lattice represent neurons, and the edges of the lattice represent the synaptic connections. Each vertex v is assigned a type: inhibitory or excitatory. The dynamics of propagation of the initial activity captures features of the “integrate-and-fire” model. We study the spread

Graphical modeling of stochastic processes driven by correlated noise

We study a class of graphs that represent local independence structures in stochastic processes allowing for correlated noise processes. Several graphs may encode the same local independencies and we characterize such equivalence classes of graphs. In the worst case, the number of conditions in our characterizations grows superpolyno-mially as a function of the size of the node set in the graph. W

Increased fat mass index is associated with decreased glomerular filtration rate estimated from cystatin C. Data from Malmö Diet and Cancer cohort

Background This study aims to describe associations of obesity and CKD in a Swedish urban population. The impact of fat mass, from bioimpedance analysis, on eGFR based on cystatin C and/or creatinine is studied. Methods 5049 participants from Malmö Diet and Cancer Study the cardiovascular arm (MDCS-CV) with available body mass composition (single frequency bioimpedance analysis) and cystatin C mea

Gender Differences in Tournament Choices: Risk Preferences, Overconfidence, or Competitiveness?

A long line of laboratory experiments has found that women are less likely to sort into competitive environments. Although part of this effect may be explained by gender differences in risk attitudes and self-confidence, previous studies have attributed the majority of the gender gap to gender differences in a competitiveness trait. I re-examine this result using a novel experiment that allows me

Discretion, Automated Decision-Making and Public Values. : Background and Test of an Approach for Unpacking Human and Technological Agency

This study aims to develop a theoretical and analytical approach for studying discretion, automated decision-making (ADM) and the consequential public values. This is achieved through our proposed approach, an overview of literature and an empirical test. The context of our empirical test is decisions made about economic support in social work. The research questions are as follows: 1) What are th

Pilot study to evaluate tools to collect pathologist annotations for validating machine learning algorithms

Purpose: Validation of artificial intelligence (AI) algorithms in digital pathology with a reference standard is necessary before widespread clinical use, but few examples focus on creating a reference standard based on pathologist annotations. This work assesses the results of a pilot study that collects density estimates of stromal tumor-infiltrating lymphocytes (sTILs) in breast cancer biopsy s

Legal Status of Information Society Service Providers (Sweden) : Phase 2

Follow-up survey on legal status of information society service providers in the post-CDSM Directive era in Sweden, focusing on service providers as intermediaries and as users of copyright-protected content (March 2022). Phase 2 report, part of ReCreating Europe project WP6 - Intermediaries.

Policies for a Circular Economy: Part 3

Policies are needed to ensure a circular economy. In the final episode of our mini-series on the circular economy, we explore the role of policy and the need for research to ensure policies like the European Green Deal promote a circular economy for sustainability. We discuss the trade-offs of slowing resource loops and energy efficiency, for example, knowing when to exchange your LED lightbulb fo

Circular Business Models for Sustainability: Part 1

The circular economy is promoted by government and industry as an approach to reduce resource consumption while maintaining a high standard of living. In this episode, we explore circular business models that leverage strategies of closing, narrowing or slowing resource loops. This episode is the first of three episodes part of our mini-series on the circular economy. We invite PhD Candidate Kathe

Joining Forces for Sustainability: The value of interdisciplinary education

Our global sustainability challenges are complex and require partnerships and collaboration across disciplines and sectors. As such, as a society, we must value interdisciplinary perspectives and work together to address these challenges. In this episode, we discuss the value of interdisciplinary education to address our complex sustainability challenges. We share the experience from our two inter

Topical diphenylcyclopropenone plus topical 0.5% anthralin versus topical diphenylcyclopropenone alone for the treatment of chronic extensive alopecia areata : A split-scalp, double-blind, controlled study

Background: The combination of diphenylcyclopropenone (DCP) and anthralin may demonstrate synergistic effects in the treatment of chronic extensive alopecia areata (AA).Objective: The objective of the study was to compare the efficacy of the combination therapy of topical DCP and topical 0.5% anthralin versus topical DCP alone for the treatment of chronic extensive AA.Materials and Methods: Ten pa

Renewable Energy Adoption: Is current growth enough to meet future climate targets?

Every year, the world adds more renewable energy production capacity than the year before. But, looking historically, is this growth enough to achieve our climate targets? According to a recent publication in ‘Nature Energy’, the short answer is “no” – to meet the climate goals requires decades of growth in renewables at rates higher than those observed historically in most countries. In this epis

Creating a system for Quality and Progress – The Purposeful Need for Technology?

The use of a learning management/assessment system has become common in higher education during the past 20 years. However, such systems are frequently not grounded in approaches to support longitudinal educational needs, such as promoting professional development. One reason may be that digital support is designed to assist with isolated tasks e.g. running MCQ tests, and therefore is not develope

Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support

Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve. Several of them relate to the
