Competition for pollen deposition space on pollinators generates last-male advantage

Many plants have precise pollen placement strategies, ensuring that large amounts of pollen are deposited on small and discrete areas of pollinators' bodies. This may lead to male–male competition if pre-existing pollen (1) is smothered or displaced by pollen from subsequent male flowers or (2) prevents subsequent pollen from attaching to pollinators. We investigated these alternative hypotheses u

The Physical Activity Health Paradox in Type 2 Diabetes

Introduction: The physical activity health paradox refers to the contrasting associations of leisure-time physical activity and occupational physical activity with cardiovascular disease, but whether this applies to Type 2 diabetes risk is unknown. This study aimed to investigate the physical activity health paradox and age-specific Type 2 diabetes. Methods: Working adults (N=5,866) in Denmark age

Improving crop yield prediction in Sweden using satellite remote sensing and the ecosystem model LPJ-GUESS

Meeting the food demand of a growing global population with limited agricultural resources is one of the greatest challenges of the 21st century. Crop yield is highly sensitive to weather variability and climate extremes, which are becoming more frequent due to climate change. Accurate regional yield prediction is essential for helping farmers adapt, ensuring food security, and strengthening the r

How circular are large corporations? Evidence from a large-scale survey with senior leaders

The circular economy has been promoted as a way for corporations to radically improve their resource efficiency and effectiveness by narrowing, slowing, closing and regenerating resource flows. However, the degree of implementation of these circular strategies across different geographies and industries is little understood. We conducted a large-scale survey with senior leaders in large corporatio

Features and dolomitizing mechanisms in inner platform facies across the Permian–Triassic boundary (External Dinarides, Croatia)

The strata encompassing the Permian–Triassic boundary interval capture a pivotal period in Earth's history, with significant changes in Phanerozoic Earth system dynamics, culminating in a severe mass extinction. In carbonate platforms, this boundary is marked by a shift from skeletal to microbial carbonate production. Whereas extensive research has focused on the End-Permian Mass Extinction in ope

Truth-Telling in a Priority Pricing Mechanism

This paper studies the impact of truth-telling preferences on aggregate consumer welfare within a priority pricing (PP) mechanism. Traditional models assume individuals always misrepresent private information to maximize payoffs, yet recent evidence suggests there may be an innate preference for truth-telling. By incorporating these preferences into a theoretical framework, I show that PP enhances

Prednisolone versus antihistamine for allergic rhinitis : No significant difference found in randomized trial

Background: Seasonal allergic rhinitis (AR) impacts public health by affecting work productivity and quality of life. The Swedish tree pollen season starts in February with alder and hazel pollination, followed by birch and ends with oak in May. Systemic corticosteroids are often prescribed when topical treatments fail, despite limited evidence supporting their efficacy. Objective: To compare the

Study of thermal diffusivity degradation on Cu-OFE copper due to proton and self-ion irradiation using in situ transient grating spectroscopy

The operation of next-generation particle accelerator facilities with increased beam power parameters and emphasis on performance and reliability signifies the need for experimental studies on material property degradation. Literature is particularly scarce regarding the effects of ionizing radiation damage on cavity components at applicable radiation conditions, with even less extant work studyin

"What have future generations ever done for us?" Future Expectations and Present Dispositions for Social-Ecological Transformations

The concept of ‘sustainable welfare’ conceptualizes welfare and wellbeing within planetary limits. Yet there is a lack of knowledge about possible social and political carriers of corresponding social-ecological transformations. For the promotion of the changes of societal core institutions that climate scientists deem necessary in the nearer future knowledge of which parts of the population are m

Researchers of the far right as intersectional subjects: Three arenas for emotional labour

This conceptual article examines the relational dynamic between the research field focusing on the far right and those critical scholars that endeavour to undertake these studies. It is theoretically anchored in the field of political science scholarship that recognises the key role played by gender in understanding both the ideological underpinnings and the workings of various far-right entities

Encountering children with suspected neurodevelopmental disorders in Child Health Services : Swedish nurses' experiences

Purpose: To describe nurses' experiences encountering children with suspected neurodevelopmental disorders in Child Health Services. Design and methods: This qualitative inductive study was conducted in Sweden. Twenty nurses were interviewed individually on a virtual platform using a semi-structured interview guide with open-ended and explorative questions. Interviews were audio recorded and trans

Neurodevelopmental brain reserve in behavioural variant Frontotemporal Dementia

Background: Behavioural variant Frontotemporal Dementia (bvFTD) is an early-onset dementia characterised by early anterior cingulate (AC) neuropathological insult. The AC exhibits high morphological heterogeneity, which may be classified according to the presence of a paracingulate sulcus (PCS), a tertiary sulcus that, when present, develops during the third gestational trimester and thereafter re

Alcohol impairs learning and timing of conditioned eyeblink responses

Alcohol impairs motor performance, but it remains unclear precisely why this is the case. Here, we examine the effects of alcohol intoxication on conditioned eyeblink responses, a form of classical conditioning dependent on the cerebellum. In experiment 1, the conditioned responses of 18 students before and after alcohol consumption up to 1 ‰ were compared against the performance of 26 non-drinkin

EzSkiROS : enhancing robot skill composition with embedded DSL for early error detection

When developing general-purpose robot software components, we often lack complete knowledge of the specific contexts in which they will be executed. This limits our ability to make predictions, including our ability to detect program bugs statically. Since running a robot is an expensive task, finding errors at runtime can prolong the debugging loop or even cause safety hazards. This paper propose

”Vad väntar efter supervalåret 2024?”

Utfallet av parlamentsvalen i Europa får troliggen större påverkan på Sverige än Trump, skriver Fredrik N G Andersson, docent i nationalekonomi vid Lunds universitet.

Reduction of artifacts associated with missing data in coherent diffractive imaging

Coherent diffractive imaging experiments often collect incomplete datasets containing regions that lack any measurements. These regions can arise because of beamstops, gaps between detectors, or, in tomography experiments, a missing wedge of data due to a limited sample rotation range. We describe practical and effective approaches to mitigate reconstruction artifacts by bringing uniqueness back t
