Contrasting population genetic structures of freshwater eels ( Anguilla marmorata, A. bicolor, A. mossambica ) from Madagascar

Abstract Freshwater eels (genus Anguilla ) are of major biological and commercial interest due to their complex catadromous life cycle and as a high‐value fishery resource, but the biology of tropical species is still poorly understood. This study investigates the genetic integri...

Airborne eddy covariance measurements of ocean-air VOC fluxes: Distinguishing signal from noise

Abstract. Ocean-atmosphere exchange plays an important but uncertain role for many volatile organic compounds (VOCs). Airborne eddy covariance (EC) enables direct flux quantification over large areas, but VOC applications have largely been performed over land. Here we combine the...

Screen Use and Children’s Language Development From Ages 5 to 7 Years

Importance Concerns about screen use and early language development are widespread, and prior research has reported mixed findings. Many studies have not distinguished baseline differences from developmental change, leaving uncertainty about whether screen use is associated with...

Medication transitions and predictors of illicit substance use during opioid agonist treatment: a three-year follow-up study

Abstract Background For opioid use disorder (OUD), pharmacological therapy using methadone or buprenorphine, plus psychosocial support, is the most effective opioid agonist treatment (OAT). Long-acting injectable buprenorphine (LAIB) is the newest buprenorphine formulation. This...

From Neuropeptides to Toxins: Illuminating the Origins of Venom Complexity in Cone Snails

Abstract New genes and gene functions are key drivers of evolutionary innovation. Venomous animals, such as cone snails, provide striking examples of gene innovation, yet the mechanisms by which toxins arise remain poorly understood. Using the Conus textile genome, we uncover how...

Adolescents at the crossroads: genetic associations between psychotic symptoms and antisocial traits

<title>Abstract</title> Antisocial behaviour in youth has serious consequences at individual and societal level. Adolescence is also a critical period for the emergence of prodromal psychosis symptoms. Their co-occurrence may aggravate aggression and lead to severe adverse outcom...

Adult support and its role in the association between childhood adversity and quality of life in a population-based study

Abstract Background Childhood adversities can have long-term impacts on quality of life (QoL), health, and well-being. We surveyed an adult population to assess the prevalence of three common adverse childhood experiences (ACEs): parental alcohol problems, parental mental illness...

Voice metrics and workload in helicopter rescue: insights from ninety-six cockpit recordings

The relationship between subjective workload and task performance is multifaceted. In aviation research, task performance is typically evaluated using multiple variables. Voice metrics can provide valuable insights regarding operational improvements and offer objective assessment...

Measuring Ocean Surface Waves

Abstract Propagating waves on the ocean surface can be represented as a stochastic process whose statistics are characterized by a spectrum. This paper reviews methods for measuring the wave spectrum and related quantities. Observations begin by sensing fluid dynamical properties...

Methods of Selective Inference for Linear Mixed Models: A Review and Empirical Comparison

Summary Selective inference aims at providing valid inference after a data‐driven selection of models or hypotheses. It is essential to avoid overconfident results and replicability issues. While significant advances have been made in this area for standard regression models, rel...

The societal costs of suicide – a Norwegian register-based study

Suicide constitutes a serious public health problem, leaving many more bereaved. It also represents a major economic burden to society, and the aim of this study was to estimate the societal costs of suicide in Norway. This cost-of-illness study included direct suicide-related co...

Aphasia treatment research: a decision-making tool to guide the design of phased trials from the Collaboration of Aphasia Trialists (CATs) trials for aphasia panel

Background Systematic reviews of randomised controlled trials with meta-analyses indicate that speech and language therapy for aphasia after stroke is effective in improving communication. However, high-quality evidence to identify an intervention’s target population (who), regim...

Association of Higher Caries Levels With Reduced Oral Health-Related Quality of Life Among Somali School Children in Hargeisa

Background Evidence on how Somali children are affected by their oral health status is limited. This study aimed to assess oral health-related quality of life (OHRQoL) among 12-year-old schoolchildren in Hargeisa, Somaliland, and to examine the potential association of dental car...

No Differences in Blood Pressure or Anthropometric Measures in 3‐Year‐Old Children After a Randomized Mediterranean Dietary Intervention During Pregnancy in Norway

AIM: The randomized controlled Cardiovascular Risk Reduction Diet in Pregnancy (CARRDIP) study demonstrated that a Mediterranean diet during pregnancy could alter maternal lipid levels, improve fetoplacental perfusion, and reduce preterm delivery rate. Here, we examine whether th...

Spatial organization of the tumor-immune microenvironment in ER-positive breast cancer with treatment remodeling and associated clinical responses

The tumor microenvironment influences treatment response in ER-positive breast cancer, but what distinguishes responders from non-responders and how it changes during treatment is poorly understood. Here, we profiled ER-positive breast tumors treated with neoadjuvant chemotherapy...

Liver Transplantation for Nonresectable Colorectal Liver Metastases

OBJECTIVE: To determine if stringent selection criteria could result long-term overall survival and to determine the proportion of patients that most likely were cured by the transplantation. SUMMARY BACKGROUND DATA: Liver transplantation is a potentially curative option for pati...

The relationship between language prediction and action prediction in toddlers and adults

Prediction plays a key role in both action processing and language comprehension, yet it remains unclear whether individual differences in action prediction are related to individual differences in language prediction. Using eye-tracking, we examined predictive looking behaviour...

Immigrant parents’ perspectives on healthy growth in children: a qualitative study

In many high-income countries, children with immigrant background exhibit a higher prevalence of obesity, compared to non-immigrant children. We explored the perspectives of immigrant-background parents regarding their children’s healthy growth, feeding practices, physical activi...

Bridging Nanoscopic Surface Heterogeneity and MacroscopicNucleation Rates: A Perspective on Probabilistic Approaches

Abstract Predicting the number of newly formed crystals and their spatial distribution on surfaces or within pore spaces matters across many fields, from structural biology to coupled fluid flow and reactive transport in porous media to atmospheric physics. Nucleation occurs at m...

Glacier surges on James Ross Island, Antarctica, and their relationship with climate

Abstract. Although the Antarctic Peninsula has a similar climate to that of other regions hosting surge-type glaciers, only one glacier surge has been previously observed in this region. We examined ice surface velocity, elevation and terminus position changes of Antarctic Penins...
