The flow behind nine different arrays of cylinders is experimentally investigated via Particle Image Velocimetry (PIV) at a Reynolds number of Re ∼ 100 based on the diameter of the cylinders. Each array consists of a column of four cylinders in front and three in the rear. The horizontal distance between the two columns and the vertical distance between the cylinders within each column are varied

Context. The second Gaia data release, DR2, contained radial velocities of stars with effective temperatures up to Teff = 6900 K. The third data release, Gaia DR3, extends this up to Teff = 14 500 K. Aims.We derive the radial velocities for hot stars (i.e., in the Teff = 6900-14 500K range) from data obtained with the Radial Velocity Spectrometer (RVS) on board Gaia. Methods. The radial velocities

Coastal areas are undergoing significant socio-ecological changes which intensify the control, extraction, and contestation over coastal resources. These changes have severe justice implications for those strongly dependent on coastal resources, including small-scale aquaculture (SSA) farmers. Yet, research on injustices faced by SSA farmers remains limited. By using a case study approach focused

Ultrasound is a promising neural stimulation modality, but an incomplete understanding of its range and mechanism of effect limits its therapeutic application. We investigated the modulation of spontaneous hippocampal spike activity by ultrasound at a lower acoustic intensity and longer time scale than has been previously attempted, hypothesizing that spiking would change conditionally upon the av

Despite the amount of research that has been conducted on phantom limb pain (PLP), the etiology of the condition remains unknown, and treatment options are limited. After an individual loses a limb, the brain continues to detect the presence of the missing limb even though it is no longer attached to the body, likely through proprioceptive signals. The majority of patients with amputations either

We theoretically investigate the extractable work in single molecule unfolding-folding experiments with applied feedback. Using a simple two-state model, we obtain a description of the full work distribution from discrete to continuous feedback. The effect of the feedback is captured by a detailed fluctuation theorem, accounting for the information aquired. We find analytical expressions for the a

Background: Road vehicle transportation is essential to support community access and participation for all children. However, little is known about the transport patterns of children with disabilities and medical conditions and their caregivers’ experiences supporting them to be transported safely in road vehicles in Australia. Aim: To understand the transport needs of children with disabilities a

Ultra millimeter-wave (mmWave) radars have become a vital sensor in automotive, surveillance, and consumer electronics thanks to its precise measurements and low power consumption. However, they required a precise control to coordinate their different modules and produce meaningful data. In this thesis work, we introduce an approach to perform the control and coordination of the radar based in mic

BACKGROUND: Painters are among the occupational groups that most commonly experience occupational contact dermatitis, but few investigations exist concerning this occupation.OBJECTIVES: To characterize painters with contact dermatitis and identify the most common allergens associated with the occupation. Materials and methods. All patch test results of 219 painters and 1095 matched controls regist

A metal pipe forming part of an ethnographic collection which had arrived in Lund University by around 1820 is said to have been recovered from ‘wildmen’ in North America. This short paper provides a description and images of the object and discusses a set of issues that it implies. Where was it made, by whom, when and by what method? Can credible comparisons be found? Could it possibly have been

Single-ion magnets (SIMs) constitute the ultimate size limit in the quest for miniaturizing magnetic materials. Several bottlenecks currently hindering breakthroughs in quantum information and communication technologies could be alleviated by new generations of SIMs displaying multifunctionality. Here, ultrafast optical absorption spectroscopy and X-ray emission spectroscopy are employed to track

The world needs rapid transformation if we are to shift towards more just and regenerative socio-ecological futures. In merging scholarly fields of transformation studies, regeneration and ethics of care this thesis explores the connection between inner-outer regeneration through the in-depth study of a transformative caring process. With a focus on lived experience and affects, this study conduct

Central aspects of emotional experiences are often well remembered at the expense of background details. Previous studies of such memory trade-offs have focused on memory after brief delays, but little is known about how these components of emotional memories change over time. We investigated the evolution of memory for negative scenes across 30 min, 12 daytime hours spent awake, and 12 nighttime

Proton magnetic resonance spectroscopy (1H-MRS) offers a growing variety of methods for querying potential diagnostic biomarkers of multiple sclerosis in living central nervous system tissue. For the past three decades, 1H-MRS has enabled the acquisition of a rich dataset suggestive of numerous metabolic alterations in lesions, normal-appearing white matter, gray matter, and spinal cord of individ

Hard-to-reach (HTR) energy users encompass individuals who are physically difficult to reach, underserved, or challenging to engage and motivate in demand-side energy programmes. Given a mix of societal challenges (e.g. inequity, energy poverty, decarbonisation, the COVID-19 pandemic), HTR energy users are receiving increasing attention. However, there is a lack of knowledge on the performance of

The hippocampus is a primary region affected in Alzheimer's disease (AD). Because AD postmortem brain tissue is not available prior to symptomatic stage, we lack understanding of early cellular pathogenic mechanisms. To address this issue, we examined the cellular origin and progression of AD pathogenesis by comparing patient-based model systems including iPSC-derived brain cells transplanted into
