The Gravitational-wave Optical Transient Observer (GOTO) Fast Analysis and Spectroscopy of Transients (FAST) Surveys

Abstract The study of young and fast astronomical transients is often limited by the difficulty of acquiring data, particularly spectra, within hours to days of explosion. Historically, follow-up programmes have rarely obtained spectra until many days after discovery; coupled wit...

Phenanthrene disrupts calcium transients and inhibits INCX in zebrafish ( Danio rerio ) ventricular myocytes

Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) that is derived from fossil fuels and is present in most PAH mixtures found in water, air and soil. It has been shown to affect cardiac function of vertebrates, including fish. We investigated the effects of phenanthrene on...

The clinical benefit of routine PET/CT imaging in asymptomatic head and neck squamous cell cancer patients one year post-treatment

BACKGROUND: The incidence of head and neck cancer is increasing, creating a growing need for follow-up strategies. The benefit of routine PET imaging beyond six months after treatment in asymptomatic patients remains unclear. OBJECTIVE: To assess whether routine PET/CT or PET/MRI...

Satisfaction of antenatal care services and its associated factors among pregnant women in selected public health facilities in Kandahar, Afghanistan

Research indicates that satisfaction with antenatal care (ANC) services remains suboptimal across several low-and middle-income countries (LMICs). However, there is a research gap on the satisfaction of ANC services in Afghanistan. Therefore, this study aims to assess satisfactio...

Network structure of depressive symptoms in father–mother–adolescent triads: Do networks differ by age?

Adolescents’ and their parents’ depression influence each other reciprocally. However, the specific mechanisms that contribute to the shared occurrence of depression at the symptom level within families remain unclear. Additionally, these relationships may vary across different s...

Biomechanical consequences of coronoidectomy on mandibular condylar stress distribution under simulated traumatic loading: a comparative finite element analysis

The coronoid process is a major temporalis insertion site and may contribute to load distribution within the mandibular ramus–condyle complex. Coronoidectomy is well established for restoring mouth opening in trismus and ankylosis, but its biomechanical consequences for condylar...

Gut microbiome maturation in early childhood interacts with host genetics to predict type 1 diabetes risk

Prospective evidence linking early-life microbiome development and host genetics with type 1 diabetes (T1D) risk is limited. Here, we describe how gut microbiome maturation and host genetics influence T1D risk in the TEDDY study. We analysed 12,151 longitudinal metagenomes and ho...

Engaging Creative-Sector Stakeholders for Place Branding – A University as a Value Integrator

Value co-creation has become central to place branding as urban areas increasingly seek to improve their attractiveness and cultural vitality. This study investigates how a university fosters value co-creation by engagingFootnote1 creative sector in place branding, drawing on th...

Unravelling the mechanisms of cyanobacterial resilience in photosynthetic living materials

Abstract Background Photosynthetic cyanobacteria entrapped in artificial solid matrices, such as alginate hydrogels, can sustain active photosynthesis and bio-production of chemicals for months, yet the cellular adaptations underlying this remarkable resilience remain poorly unde...

Effect of CFRP strip width, spacing, and anchors on the axial and flexural performance of RC columns

This study experimentally investigates the effectiveness of strengthening reinforced concrete (RC) columns with carbon fiber-reinforced polymer (CFRP) strips to enhance their axial load capacity and nonlinear deformation behavior under both concentric and eccentric axial loading....

Paler within the city: Carotenoid‐based colouration covaries negatively with the proportion of impervious surface in great tit ( Parus major ) territories across Europe

Urbanisation alters resource availability and exposes wildlife to novel environmental stressors, potentially driving phenotypic divergence. Carotenoid-based plumage colouration is a condition-dependent trait linked to dietary carotenoid acquisition and physiological allocation tr...

B2B opportunity forecasting with explainable segmentation and cost-sensitive prediction

Abstract Business-to-business (B2B) sales forecasting is critical for organizational growth, but available data are often small, imbalanced, and noisy, complicating the identification of high-potential customers. This study proposes a hybrid, explainable framework for opportunity...

Comparison of Dal Pont, Hunsuck, Wolford, and Posnick Sagittal Split Osteotomy Designs: An Ex Vivo Ovine Study

OBJECTIVE: This ex vivo experimental study aimed to comparatively evaluate 4 sagittal split osteotomy designs (Dal Pont, Hunsuck, Wolford, and Posnick) using ovine hemimandibles with respect to operative time, lingual split pattern, the occurrence of bad splits, and the position...

Influence of carbonate apatite nanoparticles incorporated into commercial dental adhesives on immediate and long‐term microtensile bond strength

Abstract This study assessed whether integrating carbonate apatite nanoparticles with a CO 3 /PO 4 molar ratio of 5 (CA5n) into commercial adhesives affected the immediate or the long‐term microtensile bond strength ( µ TBS) between composite resin and dentin. Scotchbond Multipur...

Early Language Difficulties in Association With Later Need of School Support Services in Very Preterm Children – A Longitudinal Follow‐Up Study

ABSTRACT Aim School performance requires a wide spectrum of developmental abilities including cognitive, social and behavioural skills. We aimed to study the association between developmental difficulties at 5 years and the received school support services at 8 and 11 years in ch...

Eco-evolutionary dynamics and environmental detoxification jointly shape bacterial community response to antibiotic perturbation

Microbial communities frequently encounter recurrent antibiotic disturbance, yet how ecological, evolutionary, and environmental processes jointly shape community responses remains unresolved. Here, we use priming to describe the history-dependent effect whereby prior exposure al...

Eudaimonic well-being in relation to urban nature: pathways to multiple nature values

Urban nature is increasingly recognized as essential for mental well-being. This study examines eudaimonic well-being – value-based, deeper well-being – by exploring how nature supports self-acceptance, autonomy, purpose in life, personal growth, good social relations, and enviro...

Pharmacokinetics and efficacy of tank water-administered BRAF-inhibitor dabrafenib in a zebrafish melanoma model

Zebrafish models are widely used to study BRAF-mutant melanoma biology. However, long-term treatment of adult fish with small molecule BRAF inhibitors remains challenging, and pharmacokinetic data to inform rational dosing strategies are largely lacking for most small molecules i...

Diagnosis of urinary tract infection in the emergency department – a real infection or an alarming indication for comprehensive geriatric assessment? A retrospective follow-up study

Purpose To investigate whether urinary tract infection (UTI) diagnoses assigned in the emergency department (ED) were true UTI infections, characterize hospitalized UTI patients, and analyze the 12-month mortality and institutionalization rates. Methods A retrospective study amon...

Additive Problems with Primes from a Thin Bohr Set

Abstract For an irrational alpha element of double struck upper R α ∈ R $\alpha\in {{\mathbb{R}}}$ and any beta element of double struck upper R β ∈ R $\beta\in {{\mathbb{R}}}$ , we consider additive problems with the set of primes satisfying StartMetric alpha p plus beta EndMetr...
