During solar storms, the Sun expels large amounts of energetic particles (SEP) that can react with the Earth’s atmospheric constituents and produce cosmogenic radionuclides such as 14C, 10Be and 36Cl. Here we present 10Be and 36Cl data measured in ice cores from Greenland and Antarctica. The data consistently show one of the largest 10Be and 36Cl production peaks detected so far, most likely produ

Context. This work is part of the Gaia Data Processing and Analysis Consortium papers published with the Gaia Early Data Release 3 (EDR3). It is one of the demonstration papers aiming to highlight the improvements and quality of the newly published data by applying them to a scientific case.Aims. We use the Gaia EDR3 data to study the structure and kinematics of the Magellanic Clouds. The large di

Rationale & Objective: A healthy lifestyle promotes cardiovascular health and reduces cardiac-related mortality in the general population, but its benefits for people receiving maintenance hemodialysis are uncertain. Study Design: Prospective cohort study. Setting & Participants: 5,483 of 9,757 consecutive adults receiving maintenance hemodialysis (January 2014 to June 2017, median dialysi

Extending beyond previous research biases towards large cities or analyses based largely on one type of urban agriculture (UA) (such as market gardening, or home gardening), this research aimed to investigate all forms of UA within two intermediate-sized Ghanaian cities (Techiman and Tamale). Where was being farmed? For whom, and why? The paper considers how findings compare to Ghana's larger citi

Explosive volcanic eruptions can reach the stratosphere and cause elevated concentrations of sulphate particles for months to years. When these particles descend into the troposphere, they can impact cirrus clouds though to what degree is unknown. In this study, we combine three satellite data sets to investigate the impact of downwelling sulphate aerosol on midlatitude cirrus clouds during spring

Continuum modeling of granular media is made possible by the existence of a length scale at and above which grain-resolved properties can be meaningfully homogenized. Progress has been made in identifying such length scales relevant to local structural properties such as porosity. However, a systematic analysis of scales above which different mechanical properties can be homogenized has yet to eme

OBJECTIVE: The presence of tachycardia in critically ill patients is frequently used as an indication of severity of illness and to guide treatment decisions but can be influenced by body temperature, thus confounding its interpretation. There are few data available on the relationship between body temperature and heart rate in critically ill patients. DESIGN: Retrospective analysis of prospective

Marine sediments of the lowermost Eocene Stolleklint Clay and Fur Formation of north-western Denmark have yielded abundant well-preserved insects. However, despite a long history of research, in-depth information pertaining to preservational modes and taphonomic pathways of these exceptional animal fossils remains scarce. In this paper, we use a combination of scanning electron microscopy coupled

Resistance to Russia’s aggression is being shaped by how decentralised and data-centric global rules have become.

Historically, aerosols of anthropogenic origin have offset some of the warming from increased atmospheric greenhouse gas concentrations. The strength of this negative aerosol forcing, however, is highly uncertain-especially the part originating from cloud-aerosol interactions. An important part of this uncertainty originates from our lack of knowledge about pre-industrial aerosols and how many of

Imaginary companions and the characteristics of the children who invent them were explored through interviews. Twenty-six children took part. The first aim was to explore the phenomenon in general, the second to investigate the functions of imaginary companions. General findings concerned the kinds of imaginary companions and some facts about the children who created them. The imaginary companions

The aim of the study was to investigate the relationship between coping and health problems in the context of gender and level in the organization. Questionnaire data were collected from 279 women and men (100 managers and 179 non-managers) at a sales department in a Swedish telecom company in which men and women worked at similar tasks. It was hypothesized that, if gender and level in the organiz

Increasing pressure on innovativeness and collaboration is supposed to strengthen the importance of geographical proximity in innovation systems. But simultaneously there are;globalization forces' and information and communication technology (ICT) developments that stress wider contexts and different dependencies to place and distance. With case studies of innovative firms at IDEON Science Park in

A good design of a Boolean function used in a stream cipher requires that the function satisfies certain criteria in order to resist different attacks. In this paper we study the tradeoff between two such criteria, the nonlinearity and the resiliency. The results are twofold. Firstly, we establish the maximum nonlinearity for a fixed resiliency in certain cases. Secondly, we present a simple searc

Closely related sympatric species are expected to evolve strong species discrimination because of the reinforcement of mate preferences [1-4]. Fitness costs of heterospecific matings are thought to be higher in females than in males, and females are therefore expected to show stronger species discrimination than males [5, 6]. Here, we investigated gender and species differences in sexual isolation

Effectors of the innate immune system, the anti-bacterial peptides, have pivotal roles in preventing infection at epithelial surfaces. Here we show that proteinases of the significant human pathogens Pseudomonas aeruginosa, Enterococcus faecalis, Proteus mirabilis and Streptococcus pyogenes, degrade the antibacterial peptide LL-37.
