The effects of atmospheric aerosols are key uncertainties in climate models. One reason is the complex aerosol composition which includes a relatively large fraction of organics. Another reason is the small size of aerosols, which makes surface effects and processes important. These two factors make surface-active organics relevant for atmospheric aerosols, as they can affect crucial processes, su

Accurate labels are critical for deriving robust machine learning models. Labels are used to train supervised learning models and to evaluate most machine learning paradigms. In this paper, we model the accuracy and cost of a common weak labeling process where annotators assign presence or absence labels to fixed-length data segments for a given event class. The annotator labels a segment as "pres

Background: Despite considerable interest in the consequences of benzodiazepine and benzodiazepine-related Z-drug (BZDR) use, little is known about whether and how initiation of BZDR treatment relates to the development of alcohol- and drug-related problems. Aims: This study aimed to examine the association of incident BZDR dispensing with subsequent alcohol- and drug-related problems. Methods: Th

Event cameras and LiDARs provide complementary yet distinct data: respectively, asynchronous detections of changes in lighting versus sparse but accurate depth information at a fixed rate. To this day, few works have explored the combination of these two modalities. In this article, we propose a novel neural-network-based method for fusing event and LiDAR data in order to estimate dense depth maps

Many animals undergo irreversible ontogenetic color changes (OCCs), yet these changes are often overlooked despite their potential ethological relevance. The problem is compounded when OCCs involve wavelengths invisible to humans. Wall lizards can perceive ultraviolet (UV) light, and their conspicuous ventral and ventrolateral coloration—including UV-reflecting patched—likely serves social communi

Asthma is a common, multifaceted respiratory disease with a major impact on quality of life. Despite increased insights into mechanisms underlying various asthma phenotypes and endotypes and the availability of targeted biologic treatment options, the disease remains uncontrolled in a substantial proportion of patients with risk of exacerbations, requiring systemic corticosteroids, and with progre

Fine-grained windblown deposits (loess) in which fossil soils (palaeosols) are preserved are excellent records of past climate. However, so far paleoclimate reconstruction studies conducted on such loess-palaeosol sequences (LPS) in SE Europe were focused on the climate changes of the last one or two glacial-interglacial cycles, while almost no attention has been directed to the climate of the cur

Normally, the measurement limit for luminescence analysis of quartz is 50-70 ka with the most widely used single aliquot regeneration (SAR) protocol, consequently, the dating of MIS 3 and MIS 4 samples or older is problematic using quartz. However, recent studies propose that the sensitivity-corrected multiple aliquot regenerative dose (SMAR) measurement technique has the potential to extend the d

BACKGROUND AND OBJECTIVE: Bacillus Calmette-Guérin (BCG) reduces disease recurrence and progression in intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). BCG-associated adverse events during instillations are common, leading to treatment cessation. Prophylactic use of quinolones in conjunction with BCG instillations is one approach for reducing BCG-associated adverse events. O

The Danube fluvial terrace in Velika Vrbica is situated at the westernmost edge of the Wallachian basin, Serbia. The profile is positioned in a gully valley with a base consisting of point bar sands interlayered with overbank clay deposits, which are together covered by loess sediments. The investigated loess-paleosol sequence (LPS) has a height of 11.15 m and has been sampled at 5 cm intervals fo

Objective: The objective of this study was to compare health-related quality of life (HRQoL) and work productivity in axial SpA (axSpA) and non-axSpA patients with chronic back pain of <2 years. Methods: Baseline and 2-year data for patients included in the SPondyloArthritis Caught Early cohort were analysed. HRQoL was assessed by the physical (PCS) and mental component summary (MCS) scores of the

We demonstrate the existence of a first-order prewetting transition of a supracritical model polymer solution adjacent to an attractive surface. The model fluid we use mimics (qualitatively) an aqueous polyethylene oxide solution and, like the actual solution, displays a closed loop 2-phase region with an upper and lower critical solution temperature. The model fluid is shown to undergo a prewetti

Climate, forest successional stage, and soil substrate age can alter herbivore communities and their effects on biogeochemical cycling, but the size and spatial variability of these effects are poorly quantified. To address this knowledge gap, we established a globally distributed network of 50 broadleaved old-growth forests across six continents, encompassing well-constrained local-scale gradient

The study discussed in this article aimed to understanding how pre-activity formulations are designed and accomplished by mothers in play interactions as everyday interactional business. Here, we report specifically on instances during the lab-based interactions where the mother orients to the lab-based task of singing with their infant, and discuss potential implications of such participant orien

Iron is indispensable for the vast majority of organisms, and iron homeostasis plays a pivotal role in both the physiology and pathogenesis of fungal pathogens. However, the underlying mechanisms by which iron homeostasis modulates fungal pathogenesis remain to be fully elucidated. We therefore focused on investigating the functions of mitochondrial iron transporter ClMrs3/4 in virulence. We condu

Digital control systems introduce unavoidable computational latencies. For some controllers this time delay inhibits practical use, even though they in theory could provide more efficient control. For example, solving an optimization problem each sampling period when using model predictive control. By sampling faster than the computation time and executing independent controllers on distributed ha

Pancreatic (PC), colorectal (CRC), hepatocellular (HCC), and gallbladder (GC) cancers together account for nearly 20% of all cancer cases. However, specific biomarkers and therapeutic targets for these cancers are lacking. Diagnosing these cancers early and providing timely, appropriate treatment to improve patient outcomes is crucial. In this context, previous studies, including ours, have highli

The 2024 Lund University Conference on Teaching and Learning, hosted by MedCUL and the Division for Higher Education Development (AHU), took place in the newly inaugurated Forum Medicum – an environment purposefully designed to inspire connection, collaboration, and exchange. The venue’s open architecture mirrored the conference theme, Connecting teachers – changing from within, underscoring the r
