Models of natural pest control : Towards predictions across agricultural landscapes

Natural control of invertebrate crop pests has the potential to complement or replace conventional insecticide-based practices, but its mainstream application is hampered by predictive unreliability across agroecosystems. Inconsistent responses of natural pest control to changes in landscape characteristics have been attributed to ecological complexity and system-specific conditions. Here, we revi

A drug screen with approved compounds identifies amlexanox as a novel Wnt/β-catenin activator inducing lung epithelial organoid formation

Background and Purpose: Emphysema is an incurable disease characterized by loss of lung tissue leading to impaired gas exchange. Wnt/β-catenin signalling is reduced in emphysema, and exogenous activation of the pathway in experimental models in vivo and in human ex vivo lung tissue improves lung function and structure. We sought to identify a pharmaceutical able to activate Wnt/β-catenin signallin

Innovation in Malmö after the Öresund Bridge

We analyze the effect of the Öresund Bridge, a combined railway and motorway bridge between Swedish Malmö and the Danish capital Copenhagen, on inventive activity in the region of Malmö. Applying difference-in-difference estimation on individual-level data, our findings suggest that the Öresund Bridge led to a significant increase in the number of patents per individual in the Malmö region as comp

Beyond Culture : Advancing the understanding of political and technological contexts in crisis communication

This study aims to theoretically advance the context-oriented tradition in crisis communication by highlighting the political and technological contexts for understanding organisational crises. Using China as a case, the study proposes a broader analytical framework that investigates the societal contexts’ impact on crisis communication from political and technological domains. The analytical fram

Pain and analgesics in patients with hard-to-heal ulcers : using telemedicine or standard consultations

OBJECTIVE: To compare consultations carried out via video with those performed in person for patients with painful, hard-to-heal ulcers, with a focus on ulcer pain and pain treatment. A further aim was to investigate predictors for pain and pain treatment.METHOD: This was a register-based, quasi-experimental study based on data from the Swedish Registry of Ulcer Treatment (RUT). A total of 100 pat

Accessibility and uncertainty : An empirical analysis of option value in transport

Are there option values for transport services? A few studies have tried to answer this question through various stated preference methods, but we do not know much about its magnitude in different contexts. In this paper, we summarize the theory on option value, present previous empirical work concerning transport, and discuss its links to accessibility. Accessibility can be seen as the end produc

Copeptin as a predictive marker of incident heart failure

AIMS: Heart failure (HF) is a common disease with increasing prevalence and poor prognosis. The vasopressin (VP) marker copeptin predicts development of diabetes mellitus, diabetic heart disease, coronary artery disease, and premature mortality. Copeptin is elevated in HF patients and predicts a worse outcome. This study aims to investigate whether copeptin can predict HF development.METHODS: Cope

The resilience of Amazon tree cover to past and present drying

The Amazon forest is increasingly vulnerable to dieback and encroachment of grasslands and agricultural fields. Threats to these forested ecosystems include drying, deforestation, and fire, but feedbacks among these make it difficult to determine their relative importance. Here, we reconstruct the central and western Amazon tree cover response to aridity and fire in the mid-Holocene—a time of less

Study the slope stability of earthen dam using dimensional analysis techniques

Slope stability is calculated using several methods. All these methods produce estimated results based on inaccurate assumptions, and their results were particularly acceptable. Furthermore, these methods rely on supposing and segmenting the surface of failure as well as performing complex calculations. This paper introduces the “Dimensional Analysis Technique” as a new approach for dealing with e

Impact of Electrical Current on Single GaAs Nanowire Structure

The impact of electrical current on the structure of single free-standing Be-doped GaAs nanowires grown on a Si 111 substrate is investigated. Single nanowires have been structurally analyzed by X-ray nanodiffraction using synchrotron radiation before and after the application of an electrical current. The conductivity measurements on single nanowires in their as-grown geometry have been realized

Repurposing Poly(3-hexylthiophene) as a Conductivity-Reducing Additive for Polyethylene-Based High-Voltage Insulation

Poly(3-hexylthiophene) (P3HT) is found to be a highly effective conductivity-reducing additive for low-density polyethylene (LDPE), which introduces a new application area to the field of conjugated polymers. Additives that reduce the direct-current (DC) electrical conductivity of an insulation material at high electric fields have gained a lot of research interest because they may facilitate the

Prevalence of Nelson’s syndrome after bilateral adrenalectomy in patients with cushing’s disease : a systematic review and meta-analysis

Purpose: Bilateral adrenalectomy (BA) still plays an important role in the management of Cushing's disease (CD). Nelson’s syndrome (NS) is a severe complication of BA, but conflicting data on its prevalence and predicting factors have been reported. The aim of this study was to determine the prevalence of NS, and identify factors associated with its development. Data sources: Systematic literature

An App Call a Day Keeps the Patient Away? Substitution of Online and In-Person Doctor Consultations Among Young Adults

The emergence of markets for online physician consultations -- direct-to-consumers telemedicine (DCT) -- is transforming healthcare services in many nations. The convenience of DCT lowers the cost of seeking care, thus potentially increasing demand. Yet, it is not known whether patients consuming online care turn to traditional providers as well. This is one of the first studies to causally assess
