The widespread contamination of urban soils by airborne microplastics (MPs) is an emerging environmental issue, particularly in urban allotment gardens with home-grown food. This study investigates the vertical distribution of MP in three such gardens in Berlin, Germany, over 90 days. Soil samples were collected at three depths (0-1 cm, 1–15 cm, and 15–30 cm) and analyzed for MP composition and oc
A complex and multi-layered liability structure with potentially overlapping claims on underlying collateral reduces expected recovery rates for creditors, which increases their incentives to keep otherwise insolvent firms afloat. Financially distressed firms may therefore seek to strategically “toxify” their capital structure to stave off future bankruptcy. In this article, we find evidence indic
Specular flashes from insect wings are useful for remote diversity assessment, yet their duration limits and constraining factors remain unknown. We studied this using sampling rates in entomological lidar system up to 40 kHz, resolving quick wing flashes down to 130μs duration from 40 m.
We present the building blocks of an energy-efficient on-chip platform for neural network applications based on III-V semiconductor nanowires and nanopillar arrays. These will work as emitting and detecting neurosynaptic nodes for spiking nanocircuits, as light sensors that emulate navigational properties of insect vision systems.
While recent cognitive science research shows a renewed interest in understanding intelligence, there is still little consensus on what constitutes intelligent behaviour and how it should be assessed. Here we propose a refined approach to biological intelligence as accurate prediction, according to which intelligent behaviour should be understood as adaptive control driven by the minimisation of u
This dissertation investigates the development of the main Danish modal particles jo, sgu, skam, nu, da, vel, nokand vist. In Modern Danish, these particles express contextualization instructions, that is, they express how theutterance relates to the interactive context. In addition to this common content core, they also share severalexpression features: they cannot be placed in the pre-field, the
Introduction. We aimed to investigate effects of soil pH and phosphate availability on bryophyte species in unshaded dry–mesic habitats, and to explore their implications for bioindication and conservation.Methods. Species abundance, pH and water-soluble phosphate data were collected from 1098 relevés in southernmost Sweden. Soil variable effects on 95 bryophyte taxa and species richness were eval
The self-assembly of magnetic nanoparticles under external magnetic fields holds great potential for the facile fabrication of functional magnetic components with a wide range of applications. This work employs a technique based on electrically charged gas-phase magnetic nanoparticles, demonstrating an additional level of control when forming one-dimensional assemblies, so-called nanochains, as an
Kommenterade utdrag ur generaldirektören och ecklesiastikministern Bengt Bergqvists (1860-1936) opublicerade memoarmanuskript på UB med fokus på beskrivningar av den fysiska miljön i det akademiska Lund 1879.
The research presented in this paper is based on interviews with 51 employees from 51 different organizations (including private and public sectors). Employees were interviewed more than once, over a period of 6 months, each interview lasted between 30 min to 1 h. The discussion in this paper is based on interviews during sessions which were explicitly dedicated to Information Systems and Cybersec
Semiconductors are at the heart of modern living. Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Second Edition, Three Volume Set captures the breadth of this important field and presents it in a single source to the large audience who study, make, and use semi
Aim: Healthcare services are in need of tools that can help to ensure a sufficient capacity in periods with high prevalence of respiratory tract infections (RTIs). During the COVID-19 pandemic, we forecasted the number of hospital admissions for RTIs among children aged 0–5 years. Now, in 2024, we aim to examine the accuracy and usefulness of our forecast models. Methods: We conducted a retrospect
Precision laser frequency stabilization is an important part of modern optical metrology, with applications ranging from atomic clocks to fundamental tests of physics. However, the frequency stability of the ultrastable cavities used in these experiments is fundamentally limited by thermal noise in the mirrors of the cavity. The thermal noise causes the atoms that form the mirrors to move randomly
Uncertainty affects people in various ways. It is frequently found to hinder investment and production in the economic sphere. In this study, we examine the empirical relationship between uncertainty and tolerance toward Muslims and Jews. Does uncertainty make people more or less tolerant? This question is particularly relevant given the prevalence of pandemics, wars, and financial crises. We inve
Droughts present a significant global challenge, particularly to forest ecosystems in regions such as eastern New South Wales, Australia, which is known for its dry climate and frequent, intense droughts. Recent studies have indicated a notable increase in tree mortality and canopy browning across this area, especially during the recent extreme drought period culminating in the Black Summer of 201
Groundwater drought, a significant natural disaster in arid and semi-arid regions, contributes to numerous consecutive issues. Due to the inherent complexity of groundwater flow systems, accurately quantifying and describing this phenomenon remains a challenging task. As a result of excessive agricultural development, the Marand Plain in northwestern Iran is experiencing both groundwater drought a
