The effects of shrub encroachment on arthropod communities depend on grazing history
(2024)Global Ecology and ConservationUnsustainable grazing is a major driver of biodiversity loss worldwide. Conservation actions such as grazing exclusion are effective strategies for halting such decline. However, we still know little how the long-term impact of grazing exclusion depends on plant–animal interactions such as those between encroaching unpalatable shrubs and ground arthropods. Here, we assessed how encroaching, unpalatable shrub species (Sarcopoterium spinosum) ...Journal Article -
Sleep position classification with a compact pressure textile sensor mattress using convolutional neural networks
(2024)Biomedical Signal Processing and ControlRobust body position classification during sleep is crucial for closed-loop robotic interventions in position-dependent sleep disorders. This work investigates a compact, custom-made textile pressure sensor to automatically classify recumbent body positions. We implemented a range of traditional classification methods, including Naïve Bayes, Decision Trees, and Support Vector Machines. Furthermore, we trained different machine learning ...Journal Article -
Consumers' macroeconomic expectations
(2024)Journal of Economic SurveysAfter the financial crisis of 2008, central banks around the world have increased their communication efforts to reach consumers, with the aim of both guiding and anchoring their inflation expectations. For the expectations channel of monetary policy to work as intended, central banks need a thorough understanding of the formation process of expectations by the general public and of the relationship between expectations and economic ...Journal Article -
Raw GNSS data collected using smartphones and low-cost receiver under optimal and sub-optimal conditions
(2024)Data in BriefThe miniaturisation and decrease of price are amongst the main current trends in the area of Global Navigation Satellite Systems (GNSS) receivers. Besides standalone receivers also receivers incorporated into Android devices can provide raw GNSS measurements thus enabling much wider options, formerly restricted to devices of much higher price. The article describes two datasets. The first was collected using a Xiaomi Mi 8 smartphone with ...Journal Article -
Phase Saturation Control on Vorticity Enhances Mixing in Porous Media
(2024)Water Resources ResearchMixing controls the fate of any solute entering porous media. Hence, an understanding of the involved processes is essential for assessing subsurface contamination and planning for its protection. However, the three-dimensional mechanisms dominating solute mixing in the presence of several fluid phases in the pore space, and their dependency on phase saturation degree (fraction of the pore volume occupied by a phase) are unknown. Here, ...Journal Article -
Spontaneous Formation of an Internal Shear Band in Ice Flowing Over Topographically Variable Bedrock
(2024)Journal of Geophysical Research: Earth SurfaceIce surface speed increases dramatically from upstream to downstream in many ice streams and glaciers. This speed-up is thought to be associated with a transition from internal distributed deformation to highly localized deformation or sliding at the ice-bedrock interface. The physical processes governing this transition remain unclear. Here, we argue that highly localized deformation does not necessarily initiate at the ice-bedrock ...Journal Article -
Magnetic resonance velocimetry of particle hydrodynamics in a three-dimensional draft tube spout-fluid bed
(2024)Chemical Engineering JournalDraft tube spout-fluid beds (DTSFB) are widely used in industry for processes that require intense mixing and high heat transfer between fluids and solid particles. The insertion of a draft tube compartmentalizes a slow-moving annular region from a high velocity flow in the draft tube, and thereby allowing for accurate control of the particle circulation rate and the gas contacting time. Due to these characteristics DTSFBs are a popular ...Journal Article -
Self-Supervised Learning of Visual Robot Localization Using LED State Prediction as a Pretext Task
(2024)IEEE Robotics and Automation LettersWe propose a novel self-supervised approach for learning to visually localize robots equipped with controllable LEDs. We rely on a few training samples labeled with position ground truth and many training samples in which only the LED state is known, whose collection is cheap. We show that using LED state prediction as a pretext task significantly helps to learn the visual localization end task. The resulting model does not require knowledge ...Journal Article -
Re-evaluating the link between the Ellsworth Mountains and East Antarctica in the Neoproterozoic: Implications for the breakup of Rodinia and the existence of Pannotia
(2024)Precambrian researchOur current understanding of the Ellsworth Mountains stratigraphy suggests the oldest sedimentary sequence (Heritage Group) was deposited in a Cambrian rift setting. This early Paleozoic age is then used as a key piercing point to help define Cambrian paleogeography for the southern paleo-Pacific margin of Gondwana, which places the Ellsworth Mountains between southern Africa and East Antarctica as part of West Gondwana. However, U-Pb ...Journal Article -
A lysyl oxidase-responsive collagen peptide illuminates collagen remodeling in wound healing
(2024)Matrix BiologyTissue repair and fibrosis involve the dynamic remodeling of collagen, and accurate detection of these sites is of utmost importance. Here, we use a collagen peptide sensor (1) to visualize collagen formation and remodeling during wound healing in mice and humans. We show that the probe binds selectively to sites of collagen formation and remodeling at different stages of healing. Compared to conventional methods, the peptide sensor ...Journal Article
