Steady pattern formation and film rupture in a two-dimensional thermocapillary thin-film model of the Bénard–Marangoni problem

We study two-dimensional, stationary square and hexagonal patterns in the thermocapillary deformational thin-film model for the fluid height h [Formula presented] that can be formally derived from the Bénard–Marangoni problem via a long-wave approximation. Using a linear stability analysis, we show that the flat surface profile corresponding to the pure conduction state destabilises at a critical

Structure-From-Motion with a Non-Parametric Camera Model

In this paper, we present a new generic Structure-From-Motion pipeline, GenSfM, that uses a non-parametric camera projection model. The model is self-calibrated during the reconstruction process and can fit a wide variety of cameras, ranging from simple low-distortion pinhole cameras to more extreme optical systems such as fisheye or catadioptric cameras. The key component in our framework is an a

Mass spectrometry imaging reveals uptake of the allergen methylisothiazolinone in ex vivo human skin

Allergic contact dermatitis (ACD) is a prevalent inflammatory skin condition triggered by allergens such as 2-methyl-4-isothiazolin-3-one (MI), a common preservative. The incidence of contact allergy to MI has fallen in Europe in recent years, attributable to government regulation limiting concentrations of MI I; however, incidence continues to rise in the USA. The pattern and extent of distributi

Demand response for residential appliances using multi-agent reinforcement learning with price and solar power uncertainty

The electricity market exhibits significant uncertainty arising from rapid fluctuations in prices, variations in load demand, and the intermittent nature of renewable energy resources. Effectively managing residential energy under these dynamic conditions is a challenging task. Demand Response (DR) offers a practical solution by enabling the flexible scheduling of energy consumption in response to

“I once was blind” : experimental manipulation of religious attitudes via choice blindness

Given ongoing debates about the nature and consequences of religious belief, effective procedures for experimentally controlling such beliefs are highly desirable. To date, however, there are few robust, replicable methods. Here, we show that the “choice blindness” paradigm can be leveraged to directly manipulate religious beliefs and attitudes in a way that avoids demand characteristics. Across t

Flood Mitigation Assessment Using a 2D-model: In the Rwandex-Magerwa Catchment, Kigali, Rwanda

I denna studie undersöktes översvämningsrisker i ett område i Rwandas huvudstad Kigali genom mätningar, observationer och modellering av ytvatten i programvaran HEC-RAS. De huvudsakliga resultaten från studien visade att mycket av den mätdata som samlades in från myndigheter i Kigali var undermåliga för kalibrering av en hydraulisk modell. Bland annat stämde ofta inte flödestoppar i regn och flödeIn this research, 2D hydraulic modelling is applied in the Rwandex-Magerwa catchment to investigate the flood conditions and to quantify needed detention volumes during extreme rainfall. In the calibration uncertainties concerning calibration data were discovered, the total precipitation and outlet flow volumes show large differences, the difference in time between flow and rain peaks intensities

Etern - Center för Radio och Digital Media

Landskrona är en stad i pulserande förändring. Staden, som har sina historiska rötter i såväl indus triarbete som kolonilotter, har under det senaste de cenniet utmanats med ett allt mer förändrat stadsliv. En stad som tidigare haft svårt att hyra ut sina mest centrala bostäder upplever nu ett ökande intresse för att bo och vistas i staden. En förändring som, om än synlig idag, kommer fortsat

Perceived and observed biases within scientific communities : a case study in movement ecology

Who conducts biological research, where they do it and how results are disseminated vary among geographies and identities. Identifying and documenting these forms of bias by research communities is a critical step towards addressing them. We documented perceived and observed biases in movement ecology, a rapidly expanding sub-discipline of biology, which is strongly underpinned by fieldwork and te

Flexibility in the diel migratory schedule of an Arctic songbird despite robust 24-h activity rhythms across the annual cycle

Many birds schedule their activity to a specific phase of the diel (24-h) light–dark cycle. Two notable exceptions are the nocturnal migration of many otherwise diurnal songbirds and the diverse activity patterns of birds during the continuous light above the Polar Circles during summer. Assumptions about the phase relationship between migratory activity and the diel cycle can be incorrect, and th

Inclusion of eco-corona formation and biotransformation in regulatory nanomaterial ecotoxicity and fate testing : review and insights from the MISTRA environmental nanosafety project

Background: The eco-corona, consisting of environmental biomolecules formed around engineered nanomaterials (ENMs) when released to the environment, has gained increasing focus in the scientific literature and its role for ENM fate and toxicity is now widely acknowledged. The European chemicals legislation, REACH, entails reporting requirements when it comes to the transformation of nanoforms. Gui

The spatiotemporal distribution of human pathogens in ancient Eurasia

Infectious diseases have had devastating effects on human populations throughout history, but important questions about their origins and past dynamics remain1. To create an archaeogenetic-based spatiotemporal map of human pathogens, we screened shotgun-sequencing data from 1,313 ancient humans covering 37,000 years of Eurasian history. We demonstrate the widespread presence of ancient bacterial,

Ancient host-associated microbes obtained from mammoth remains

Ancient genomic studies have extensively explored human-microbial interactions, yet research on non-human animals remains limited. In this study, we analyzed ancient microbial DNA from 483 mammoth remains spanning over 1 million years, including 440 newly sequenced and unpublished samples from a 1.1-million-year-old steppe mammoth. Using metagenomic screening, contaminant filtering, damage pattern

Association between neighborhood deprivation and type 2 diabetes risk among ADHD patients : a nationwide population-based cohort study

Objective: Both attention-deficit/hyperactivity disorder (ADHD) and neighborhood deprivation have been previously associated with an increased risk of type 2 diabetes (T2D). However, the potential association between neighborhood deprivation and T2D in ADHD patients remains underexplored. Our aim was to study the potential effect of neighborhood deprivation on incident T2D in patients with ADHD. M

Person-Centred Nursing in Allogeneic Stem Cell Transplantation Using a Conversation Tool : A Qualitative Study

Background: Patients undergoing allogeneic haematopoietic stem cell transplantation (allo-HCT) often face complex and evolving needs throughout recovery. Person-centred nursing (PCN) is essential in this context yet remains underexplored in specialised care settings. In Sweden, the Assessment of Rehabilitation Needs Checklist (ARNC) is commonly used in cancer care, but its role in supporting perso

The interplay and influence of anxiety and depression among men with early-stage prostate cancer and their close allies

Purpose: The purpose of this study was to explore the interplay and influence of anxiety and depression between patients with low-risk localized prostate cancer on active surveillance (AS) and their close allies. The research sought to determine if emotional states are interdependent within these dyads, hypothesizing that both actor (self) and partner (close ally) effects would be significant. Met

Threads of vulnerability : Migrant precarity and class-sensitive nostalgia in Wioletta Grzegorzewska’s autofiction

This article explores migrant precarity and class-sensitive nostalgia in the autofiction of Wioletta Grzegorzewska (Greg), a Polish-born writer whose work portrays the complexities of eastern European migration to the United Kingdom. Her narratives challenge idealized notions of transnational mobility by foregrounding linguistic displacement, economic insecurity, cultural alienation, and systemic
