Mitochondrial respiration in human peripheral blood mononuclear cells : methodology and influence of permeabilization and storage
Human peripheral blood mononuclear cells (PBMCs) can be easily sampled from healthy individuals and patients. Density gradient isolation from human blood or leukocyte concentrates yields a mononuclear cell population of mainly lymphocytes, monocytes, and natural killer (NK) cells. PBMCs are vital circulating cells of the immune system and rely on oxidative phosphorylation (OXPHOS) for their energy
På spaning efter den praktiknära forskning som flytt
Den här antologin visar vad som händer när skolans och universitetets världarmöts i genuin samverkan. Inom ramen för ULF‑satsningen vid Lunds universi‑tet har lärare, forskare, skolledare och lärarstudenter samt elever tillsammansutvecklat projekt som utgår från verkliga behov i undervisningen – och somsamtidigt bidrar till ny forskning.Genom konkreta exempel från grundskola, gymnasium och kulturs
Investigation of relationship between stress and seismic velocities on field scale
A relationship between seismic wave velocities and the stress state of a material have been largely investigated in small scale lab experiments but never on a large field scale. For investigation of this relationship on a larger scale a 3-D seismic array have been built into a full-size railroad embankment model. Using the three component geophones with vertical and horizontal sledgehammer strikes
Moving across drawing and sounding : Listening to trees
Drawing and sounding both rely on bodily movement as a basis for artistic expression. Movement provides the underlying spark that brings both visual and sonic practices to life. As part of a long-term research project titled ‘Sonic Kinesthetic Forest’, this paper reflects on a collaborative exchange between three researchers who use moving, drawing and sounding practices to deepen human relationsh
Infusing sensory knowledge into tree literacy
This workshop investigates sensory dimensions of trees as a way to build upon tree literacy efforts by researchers affiliated with the Concordia Tree Project on the Loyola Campus. As a laboratory of micro-forests for students and the Montreal community to learn about the wealth of trees on the campus, this forestry project aligns well with the cross-disciplinary project Sonic Kinesthetic Forest (S
HfO2-based memristive synapses with asymmetrically extended p-n heterointerfaces for highly energy-efficient neuromorphic hardware
The escalating energy consumption of existing artificial intelligence hardware has become a serious global issue that demands immediate action. Neuromorphic computing offers promises to drastically reduce this footprint. Here, we introduce multicomponent p-type Hf(Sr,Ti)O2 thin films for energy-efficient, resistive switching–based neuromorphic devices. We demonstrate interfacial memristors with ul
Ocean Wave Prediction for Arrays of Wave Energy Converters
Short-term wave prediction is a key enabling technology for advanced control of wave energy converters (WECs), where accurate knowledge of the incident wave field over one to a few wave periods can improve power capture, reduce structural loads, and support operational decision-making. Many existing prediction methods rely on measurements at the prediction point or dedicated up-wave sensors, which
Feature extraction and heart failure detection in ex vivo perfusion systems
This thesis investigates the detection of acute heart failure (AHF) in an exvivo heart perfusion system using hemodynamic signals. Early detection of AHF is important for improving monitoring and intervention. Experimental data was pre-processed and transformed into a beat-to-beat representation, from which physiological features were extracted. Events were labeled based on manual reductions in pu
Design Parameters for Enhanced Repairability and Remanufacturability of the Electric Front Cross Differential
This thesis investigates the remanufacturing potential of the electric front cross differential (eFXD) within the context of the circular economy (CE) and the R‑framework. Environmental assessment, mechanical validation and structured component classification are combined to identify opportunities and limitations for remanufacturing. The results show that a limited number of components, the tube h
Interaction between oxygen saturation and renal function on 30-day mortality in emergency department patients
Emerging evidence suggests that bidirectional lung–kidney crosstalk may influence outcomes, but this has not been systematically evaluated in unselected emergency department populations. We therefore examined the association between peripheral oxygen saturation (SpO₂), estimated glomerular filtration rate (eGFR), and 30‑day mortality, and tested whether the prognostic association of oxygenation wi
Evolution of the below-bandgap anisotropic refractive indices and dielectric functions of β-(AlxGa1− x)2O3 (0 < x < 0.25) determined by generalized spectroscopic ellipsometry
We determine the composition dependence of the below-bandgap anisotropic refractive indices and dielectric functions of β-(AlxGa1−x )2O3 for x up to 25% Al. We use Mueller matrix generalized spectroscopic ellipsometry and investigate a set of high quality single crystalline bulk (x = 0 %, 5 %, 10 %, 15 %, 20 %, 25 %) and thin film (4.6%, 9.7%, 12%, 15%, 16.3%, 21%) samples grown by the Czochralski
Sonic Kinesthetic Forest: Fostering Ecological Empathy
Sonic Kinesthetic Forest is an interdisciplinary research project that explores novel methodologies for studying trees and forests through embodied sound, movement and drawing practices. Our video article reflects on this interdisciplinary research through the lens of a performance piece in which embodied sound, movement and drawing practices were intricately interwoven with a forest landscape. Th
Shaping Sounds of Future Environments
This chapter presents a speculative sonic process for creatively transforming environmental sounds in response to climate scenarios. Sound and listening are explored for attuning to and expressing changing relationships in landscapes due to the effects of drought. Field recordings undertaken in landscapes of Potsdam, Germany are processed in relation to sources, patterns and environmental states t
Neuromuscular adaptation and postural muscle activity patterns during visual virtual reality stimulation : age-related differences between young and older adults
Vision provides important sensory input to postural control. Medical conditions and aging affect sensory—Central Nervous System (CNS) interactions, causing mismatches. Virtual Reality (VR) may address these by promoting recalibration from vision to other systems. Twenty-eight young adults (17 males, mean age 25.3 years) and 25 older adults (14 males, mean age 74.8 years) were included. Electromyog
Professional perspectives on roles and structural gaps in interprofessional collaboration for suicide prevention : a qualitative study
Introduction: Suicidal behavior results from a complex interplay of psychiatric, psychosocial, socioeconomic, and structural factors and requires coordinated approaches across care sectors. Interprofessional collaboration (IPC) is widely regarded as essential for bridging gaps in care, yet profession-level descriptions of how IPC is organized and where structural bottlenecks occur in suicide preve

Reducing selection bias while maintaining precision through an integrated analysis : 2-year longitudinal analysis of imaging outcomes in the SPondyloArthritis Caught Early cohort
Background: Cohort studies often use simple models, for example, completers-only or aggregated scores, to assess changes in imaging outcomes. With more data available, this introduces selection bias. Integrated analyses allow scores from multiple reading rounds; therefore, we assessed their effect on the change estimates’ precision compared with the completers-only analysis. Second, we compared ch
Viability of free-running buildings in the Nordic region
Contemporary Nordic building design prioritizes energy-efficient HVAC systems to mitigate carbon emissions. However, this approach underestimates intensifying climate risks, creating critical vulnerabilities as extreme weather and energy/resource scarcity escalate. To address this gap, a free-running building concept, eliminating heating, cooling, and mechanical ventilation, was examined for Nordi
When Places Change: Essays on Local Labor Markets and Individual Responses
This thesis consists of four self-contained empirical studies on how economic shocks and structural changes shape individual behavior and local outcomes.Paper I examines how military base closures affect young adults’ education and labor market outcomes. The results show that men respond by increasing tertiary education, while women experience improved short-term labor market outcomes, suggesting
