EDGE : The mass-metallicity relation as a critical test of galaxy formation physics

We introduce the 'Engineering Dwarfs at Galaxy Formation's Edge' (EDGE) project to study the cosmological formation and evolution of the smallest galaxies in the Universe. In this first paper, we explore the effects of resolution and sub-grid physics on a single low-mass halo (Mhalo = 109M⊙), simulated to redshift z = 0 at amass and spatial resolution of ∼ 20 M⊙ and ∼3 pc. We consider different st

Morbidity in patients with permanent hypoparathyroidism after total thyroidectomy

Background: Permanent hypoparathyroidism is common after thyroidectomy. The present study evaluated the risk for morbidity in patients operated with total thyroidectomy with and without permanent hypoparathyroidism. Methods: Data was retrieved from the Scandinavian Quality Register for Thyroid, Parathyroid, and Adrenal Surgery and cross-linked with the Swedish National Prescription Registry for Ph

Key Atmospheric Signatures for Identifying the Source Reservoirs of Volatiles in Uranus and Neptune

We investigate the enrichment patterns of several delivery scenarios of the volatiles to the atmospheres of ice giants, having in mind that the only well constrained determination made remotely, namely the carbon abundance measurement, suggests that their envelopes possess highly supersolar metallicities, i.e., close to two orders of magnitude above that of the protosolar nebula. In the framework

Kinetic diversity of amyloid oligomers

The spontaneous assembly of proteins into amyloid fibrils is a phenomenon central to many increasingly common and currently incurable human disorders, including Alzheimer's and Parkinson's diseases. Oligomeric species form transiently during this process and not only act as essential intermediates in the assembly of new filaments but also represent major pathogenic agents in these diseases. While

The Lazy Giants : APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds

We report the first APOGEE metallicities and α-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and Small Magellanic Clouds, the largest Milky Way (MW) dwarf galaxies. Our sample is an order of magnitude larger than that of previous studies and extends to much larger radial distances. These are the first results presented that make use of t

Maternal serum levels of perfluoroalkyl substances in early pregnancy and offspring birth weight

Background: Perfluoroalkyl substances (PFASs) are widespread, bioaccumulating, and persistent and show placental transfer. Emerging research indicates associations between prenatal exposure and low birth weight. The aim of this study was to assess the associations between first trimester exposure to PFASs and birth weight (BW) in the Swedish Environmental, Longitudinal, Mother and child, Asthma an

C-reactive protein as a prognostic factor in intensive care admissions for sepsis : A Swedish multicenter study

Purpose: C-reactive protein (CRP) is not included in the major intensive care unit (ICU) prognostic tools such as the Simplified Acute Physiology Score (SAPS). We assessed CRP on ICU admission as a SAPS-3 independent risk marker for short-term mortality and length of stay (LOS) in ICU patients with sepsis. Materials and methods: Adult ICU admissions satisfying the Sepsis-3 criteria to four souther

Geographies of transition—From topical concerns to theoretical engagement : A commentary on the transitions research agenda

This viewpoint takes stock with the ‘geography of sustainability transitions’ (GOST) as it is presented in the transitions research agenda. GOST has been a relatively recent addition to transition theorizing, addressing the need for greater sensitivity and attention to the scales, spatialities, and context-specific factors that shape transitions. In our view, the agenda represents a rather narrow

Digitalising the Ethnographic Field in and Post Covid-19 : How (a study of ) child rights activism in India moved online

The Covid-19 pandemic has forced us all to adapt. For ethnographic areastudies, such adaptations take place both at the level of the researcher andthe researched. This essay reflects on how the study of an Indian childrights advocacy network adapted to ‘going online’ as a consequence of thepandemic and lockdown in India. Although the researcher could no longerbe physically present in the studied s

The associations of major foods and fibre with risks of ischaemic and haemorrhagic stroke : A prospective study of 418 329 participants in the EPIC cohort across nine European countries

Aim: To investigate the associations between major foods and dietary fibre with subtypes of stroke in a large prospective cohort. Methods and results: We analysed data on 418 329 men and women from nine European countries, with an average of 12.7 years of follow-up. Diet was assessed using validated country-specific questionnaires which asked about habitual intake over the past year, calibrated us

The extreme space weather event in 1903 october/november : An outburst from the quiet sun

While the Sun is generally more eruptive during its maximum and declining phases, observational evidence shows certain cases of powerful solar eruptions during the quiet phase of solar activity. Occurring in the weak Solar Cycle 14 just after its minimum, the extreme space weather event in 1903 October-November is one of these cases. Here, we reconstruct the time series of geomagnetic activity bas

CRK2 and C-terminal phosphorylation of NADPH oxidase RBOHD regulate reactive oxygen species production in arabidopsis

Reactive oxygen species (ROS) are important messengers in eukaryotic organisms, and their production is tightly controlled. Active extracellular ROS production by NADPH oxidases in plants is triggered by receptor-like protein kinase-dependent signaling networks. Here, we show that CYSTEINE-RICH RLK2 (CRK2) kinase activity is required for plant growth and CRK2 exists in a preformed complex with the

EHS and AHS guidelines for treatment of primary ventral hernias in rare locations or special circumstances

BACKGROUND: Rare locations of hernias, as well as primary ventral hernias under certain circumstances (cirrhosis, dialysis, rectus diastasis, subsequent pregnancy), might be technically challenging. The aim was to identify situations where the treatment strategy might deviate from routine management. METHODS: The guideline group consisted of surgeons from the European and Americas Hernia Societies

Preterm birth and risk of type 1 and type 2 diabetes : a national cohort study

Aims/hypothesis: Preterm birth (gestational age <37 weeks) has been associated with insulin resistance early in life. However, no large population-based studies have examined risks of type 1 and type 2 diabetes and potential sex-specific differences from childhood into adulthood. Clinicians will increasingly encounter adults who were born prematurely and will need to understand their long-term ris

Reaching the ultimate energy resolution of a quantum detector

Quantum calorimetry, the thermal measurement of quanta, is a method of choice for ultrasensitive radiation detection ranging from microwaves to gamma rays. The fundamental temperature fluctuations of the calorimeter, dictated by the coupling of it to the heat bath, set the ultimate lower bound of its energy resolution. Here we reach this limit of fundamental equilibrium fluctuations of temperature

The role of sugar sensing and pathway selection on D-xylose utilization by Saccharomyces cerevisiae

Biorefineries have the potential to partially or entirely replace petrochemistry for the production of our daily bulk and fine chemicals. However, this replacement can only be sustainable and cost-effective if the raw material used is cheap, renewable and does not compete with the food and feed industry. One raw material meeting these criteria is lignocellulose from agricultural and forestry waste

Bilateral Teleoperation of Multiple Robots under Scheduling Communication

In this paper, bilateral teleoperation of multiple slaves coupled to a single master under scheduling communication is investigated. The sampled-data transmission between the master and the multiple slaves is fulfilled over a delayed communication network, and at each sampling instant, only one slave is allowed to transmit its current information to the master side according to some scheduling pro
