An integral equation reformulation of the Maxwell transmission problem is presented. The reformulation uses techniques such as tuning of free parameters and augmentation of close-to-rank-deficient operators. It is designed for the eddy current regime and works both for surfaces of genus 0 and 1. Well-conditioned systems and field representations are obtained despite the Maxwell transmission proble
Multi-source merging is an established tool for improving large-scale precipitation estimates. Existing merging frameworks typically use gauge-based precipitation error statistics and neglect the inter-dependence of various precipitation products. However, gauge-observation uncertainties at daily and sub-daily time scales can bias merging weights and yield sub-optimal precipitation estimates, part
BACKGROUND: As mild cognitive impairment (MCI) is typically used to identify prodromal stages of dementia, it is essential to identify MCI criteria with high diagnostic stability and prediction of dementia. Moreover, further investigation into pinpointing key factors for reversion is required to foresee future prognosis of MCI patients accurately.OBJECTIVE: To explore disparities in diagnostic sta
The mismatch of the coefficients of thermal expansion between cathode and electrolyte is one of the thorniest problems for high-performance proton-conducting solid oxide fuel cells (H–SOFCs). Here one strategy is applied by introducing the negative thermal expansion component, Y2Mo3O12 (YMO), on Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) cathode to overcome this difficulty. As a result, not only the electrol
Climate change impacts on agricultural systems are intensifying. The recent IPCC report illustrates that as temperatures climb, changes in the climate are pushing systems beyond sustainable boundaries. This is the case with certain livestock production systems (e.g. climate impacts can result in devastated supply chains or crop failures). When climate impacts are, or are projected to be, so severe
Climate change is already affecting crop production, and in some cases is undermining the viability of current crop systems.Crop research and development plays a critical role in developing the technologies and practices farmers need to maximize productivity and manage the increasing risks they face. This paper investigates how transformative adaptation - long-term, systemic change to fundamental
As climate change increasingly affects agriculture around the world, reliable, timely, and targeted information about weather and climate conditions is becoming an ever more urgent requirement for adaptation decision-making.This paper considers how transformative adaptation – long-term, systemic change to fundamental aspects of systems in response to or anticipation of severe climate change impact
The CRISPR/Cas9 system offers enormous versatility for functional genomics but many applications have proven to be challenging in primary human cells compared to cell lines or mouse cells. Here, to establish a paradigm for multiplexed gene editing in primary human cord blood-derived hematopoietic stem and progenitor cells (HSPCs), we used co-delivery of lentiviral sgRNA vectors expressing either E
Background: Cardiac arrest (CA) represents the third leading cause of death worldwide. Among patients resuscitated and admitted to hospital, death and severe neurological sequelae are frequent but difficult to predict. Blood biomarkers offer clinicians the potential to improve prognostication. Previous studies suggest that circulating non-coding RNAs constitute a reservoir of novel biomarkers. The
Adiabatic laminar burning velocities and post-flame NO mole fractions for flat, non-stretched, premixed dimethyl ether/air flames were experimentally determined with a heat flux burner combined with laser-induced fluorescence diagnostics, over equivalence ratios ranging from 0.7 to 1.6, at atmospheric pressure and initial temperatures from 298 to 338 K. The present burning velocity measurements we
This study developed an air-liquid interface (ALI) corneal model using explants bovine eyes for ocular toxicity assessment of ten chemicals and seven hair straightening mixtures. It was successfully maintained physiologically viable and normal for six days. Both eye damage (GHS cat. 1) and irritating (GHS cat. 2) chemicals induced corneal injury in our model. However, cat. 2 irritants triggered mo
The naturally occurring polyether ionophore salinomycin was previously found to display promising anti-proliferative activity against bloodstream forms of Trypanosoma brucei. Here, we report the evaluation of 20-deoxysalinomycin, a naturally occurring homolog to salinomycin, for trypanocidal and cell swelling activity. The concentration of 20-deoxysalinomycin required to reduce the growth rate of
Rapid technological improvements are democratizing access to high quality, chromosome-scale genome assemblies. No longer the domain of only the most highly studied model organisms, now non-traditional and emerging model species can be genome-enabled using a combination of sequencing technologies and assembly software. Consequently, old ideas built on sparse sampling across the tree of life have re
Background: By sharing patient stories, health care professionals (HCPs) may communicate their attitudes, values and beliefs about caring and treatment. Previous qualitative research has shown that HCPs usually associate paediatric palliative care (PPC) with death or dying and that they find the concept challenging to understand and difficult to implement. Attending to HCPs’ stories may provide a
Background: Randomised clinical trials with a factorial design may assess the effects of multiple interventions in the same population. Factorial trials are carried out under the assumption that the trial interventions have no interactions on outcomes. Here, we present a protocol for a simulation study investigating the consequences of different levels of interactions between the trial interventio
Elevator evacuation is associated with several safety benefits and can be a cost-efficient evacuation strategy in many buildings or facilities. Despite the advantages, elevator evacuation is not yet a common strategy in the built environment. In this paper, a design strategy that allows the designer to consider information needs of evacuees when designing the information and guidance measures for
Background: This study aimed to evaluate whether an increasing grade of obesity is associated with inferior outcomes after lumbar disc herniation (LDH) surgery. Methods: We retrieved data from the Swedish register for spine surgery regarding patients aged 20–64 who underwent LDH surgery from 2006–2016 and had preoperative and one-year postoperative data. A total of 4156 patients were normal weight
OBJECTIVES: Our aim was to derive, based on the SWEDEHEART registry, and validate, using the Western Denmark Heart registry, a patient-oriented risk score, the SweDen score, which could calculate the risk of 1-year mortality following a myocardial infarction (MI).METHODS: The factors included in the SweDen score were age, sex, smoking, diabetes, heart failure and statin use. These were chosen a pr
BACKGROUND: The risk of death from prostate cancer (PC) depends on age, but the age at which to start prostate-specific antigen (PSA) screening remains uncertain.OBJECTIVE: To study the relationship between risk reduction for PC mortality and age at first PSA screening.DESIGN, SETTING, AND PARTICIPANTS: The randomized Göteborg-1 trial invited men for biennial PSA screening between the ages of 50 a
BACKGROUND: Studies in men of European ancestry suggest prostate-specific antigen (PSA) as a marker of early prostate cancer (PCa) development that may help to risk-stratify men earlier in life.METHODS: We examined PSA levels in men measured up to 10+ years before a PCa diagnosis in association with PCa risk in 2,245 cases and 2,203 controls of African American, Latino, Japanese, Native Hawaiian,
