We study the Coulomb chain where particles are restricted to one dimension and experience three-dimensional Coulomb interactions with their nearest and next-to-nearest neighbours. The distances between consecutive particles are treated as random variables. It is shown that the correlation between clusters of consecutive variables decay exponentially with the number of variables separating them. Th
The last mute film in Carl Th. Dreyer’s oeuvre, The Passion of Joan of Arc (1928), is often referred to as a film “made of close-ups” and purely cinematic. Dreyer used to stress himself that close-up was the specific cinematic device that asserted film’s position as autonomous art. He especially insisted on film’s independence from theatre. Thus, it might sound quite surprising that in an intervie
Improving lignocellulosic biorefineries is a crucial step in transitioning from a fossil-based economy to a bio-based one. These biorefineries convert lignocellulosic biomass feedstocks into value-added products such as biofuels, biopower, biochemicals, and biomaterials, while also recovering valuable components from underutilized process streams. Pulp and paper mills are lignocellulosic biorefine
IntroductionAlthough Chronic Obstructive Pulmonary Disease (COPD) is generally considered a progressive condition with limited reversibility, recent data suggests potential for lung function improvement with exercise. Mechanistic insights into exercise-induced benefits remain limited, but in vitro models offer promise for understanding cellular and molecular changes. This study aims to elucidate t
This paper uses uncertainty generated by environmental change and climate crisis as a prompt to rethink the concept of vulnerability within disaster studies. Where some have sought to recover a latent political potential in vulnerability, a togetherness founded in the disclosure of insecurities to others, we argue that there is value in refusing to settle on any single meaning. This is explored di
The digital healthcare market has been growing rapidly due to the swift development of wearable devices. One notable advancement is the application of digital healthcare technology to vehicles, which is expected to provide a comfortable driving environment and prevent accidents. This study proposed user experience (UX) scenarios to apply and expand digital healthcare technology in vehicles, detail
This study compared and examined the electroencephalogram(EEG)-based driver inattention warning system with actual bus drivers in real-road environments. EEG and survey data were gathered from 20 professional bus drivers who drove their buses under the conditions in which the warning systems were turned on and off for 47 days. The analysis revealed that the ratio of the SMR-mid beta to theta(RSMT)
This article explores the rationales through which teenage students make sense of and legitimise unpaid labour in low-wage service jobs, contributing to theorising how such exploitation becomes normalised as part of their working lives. Based on 40 in-depth interviews with working school students in Sweden, it focuses on experiences of wage theft and coercive extra shifts, understood as employer s
Introduction. The EU-Horizon 2020 project REWAISE - REsilient WAter Innovation for Smart water Economy – aims to reduce drinking water consumption by 30%. In case of Sweden, the average drinking water consumption is currently 140 litres/day and person [1] and thus should be reduced to approx. 100 litres per day and person. Approximately 45 litres/day and person are currently used for toilets and w
Background: Mucin degradation is essential for understanding oral microbial adaptation, yet the enzymes involved remain incompletely understood. Herein, we have characterised two mucin-degrading proteases, MdpS and MdpS2, from the oral commensal Streptococcus oralis. Materials and methods: MdpS2 was characterised using physicochemical assays and substrate profiling and was compared to MdpS. Furthe
Jorunn Joiner and Mari Komnæs also employ digital tools, albeit other ones, to shed light on the interaction between narratives of exceptionalism, travel, and place. In ‘Mapping Nordic Exceptionalism with GIS: The Odin Migration Theory and the Search for a Northern Heritage’, they use digital mapping tools to visualise the journeys of two travellers from different centuries in their search for a N
IntroductionWater scarcity is a growing problem, with estimates showing that 40% of the world’s population could face water shortages by 2030. This issue is even worse because only 3% of the Earth’s water is freshwater, while 97% is seawater. Finding better ways to save and use water is critical to solving this problem. At the same time, renewable energy is essential for reducing carbon emissions
As decolonization transformed world geopolitics, various Eastern Europeanauthoritarian ultranationalist groups sought to instrumentalize anti-imperialism in their attempts to launch a violent overthrow of the socialist regimes of the Soviet bloc. As the USSR underwent a transformation from the radical anti-imperialism of the 1920s to certain imperial attributes following the announcement of the BrAs decolonization transformed world geopolitics, various Eastern Europeanauthoritarian ultranationalist groups sought to instrumentalize anti-imperialism in their attempts to launch a violent overthrow of the socialist regimes of the Soviet bloc.

This article explores the theoretical origins of modern Russian anti-and decolonial discourse. It has been demonstrated that the roots of Soviet anti-colonial policy are to be found in discussions about the interpretation of the right of nations to self-determination that began among the left at the end of the 19th century. The Leninist interpretation of this concept determined the Bolshevik polic
Improving the catalytic performance in the hydrodeoxygenation (HDO) of lignin oils to produce liquid fuels, while meeting industrial requirements, is important for addressing current environmental challenges. In the present study, the promoting effects of noble metals (Pd, Pt, and Ir) on the performance of the Ni–Mo/CeLa/Al2O3 catalyst were investigated in the HDO of a lignin-derived pyrolysis oil
Lignin, often considered the most undervalued part of lignocellulose, holds significant potential as a renewable source of valuable chemicals and materials. This study explores new insights into lignin recovery from Norway spruce using two fractionation strategies: (1) hydrotropic extraction (HEX), and (2) steam pretreatment (SE) followed by HEX. The effects of varying sodium xylenesulfonate (SXS)
Catalytic activity is improved by reducing particle size, followed by atomic scale structural and chemical design, allowing physical and electronic confinement of chemical conversion centers. These concepts culminate in single-atom catalysts (SACs) where active precious metal atoms are isolated and anchored on the surface of supports and thus fully utilized for chemical conversion. In contrast, me
