This paper introduces an innovative framework that enhances digital twins with deep reinforcement learning (DRL) to support maintenance in manufacturing systems. Utilizing a sophisticated artificial intelligence (AI) layer, this framework integrates real-time and historical production data from a physical manufacturing system to a digital twin, enabling dynamic simulation and analysis. Maintenance

The poplar moth, Leucoptera sinuella (Lepidoptera: Lyonetiidae), is widely distributed across Europe, Asia, and parts of Africa. It was first identified in Chile in 2015 and has since become a significant pest in the agricultural sector. Additionally, economic losses are further aggravated by the presence of L. sinuella pupae in nearby fruit orchards. This study investigated the presence of a male

Background and aims: Environmental and genetic factors predispose to cardiovascular disease. Some first-generation immigrants have a higher cardiovascular risk in Sweden, while less is known about second-generation immigrants. We aimed to analyze the risk of acute myocardial infarction (AMI) among second-generation immigrants in Sweden. Methods: We included all individuals 18 years of age and olde

Background and aim: Telomere length (TL) is a key biomarker of cellular aging, with shorter telomeres associated with age-related diseases. Lifestyle interventions mitigating telomere shortening are essential for preventing such conditions. This study aimed to examine the effects of two weight loss dietary strategies, based on a moderately high-protein (MHP) diet and a low-fat (LF) diet on TL in i

Background: National stroke clinical quality registries/audits support improvements in stroke care. In a 2016 systematic review, 28 registries were identified. Since 2016 there have been important advances in stroke care, including the development of thrombectomy services. Therefore, we sought to understand whether registries have evolved with these advances in care. The aim of this systematic rev

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
