Mutual Transformations of Arbitrary Ternary Qubit Trees by Clifford Gates

It is shown that ternary qubit trees with the same number of nodes can be transformed by the naturally defined sequence of Clifford gates into each other or into standard representation as 1-dimensional chain corresponding to Jordan–Wigner transform. Quanta 2026; 15: 24–30.

A multistate approach to disability insurance reserving with information delays

Disability insurance claims are often affected by lengthy reporting delays and adjudication processes. The classic multistate life insurance modeling framework is ill-suited to handle such information delays since the cash flow and available information can no longer be based on...

Bloch-Ogus theory for smooth and semi-stable schemes in mixed characteristic

We study Bloch-Ogus theory and the Gersten conjecture for homology theories with duality satisfying certain properties, in particular for étale cohomology with finite coefficients coprime to the residue characteristic of the base, for smooth and semi-stable schemes in mixed chara...

Early career researchers on the value and use of pre-prints

Reports on findings from a study of the impact of AI on early career researchers' communications on their attitudes to and use of pre-prints. A convenience sample of 69 science and social science ECRs based mainly in five countries-China, Malaysia, Poland, Portugal and Spain, wit...

Nonparametric Hazard Rate Estimation With Associated Kernels and Minimax Bandwidth Choice

ABSTRACT In this paper, we introduce a general theoretical framework for nonparametric hazard rate estimation using associated kernels, whose shapes depend on the point of estimation. Within this framework, we establish rigorous asymptotic results, including a second‐order expans...

Dose‒response relationship between tooth loss and cognitive impairment in older adults

Abstract Background In recent years, associations between oral health factors, including tooth loss, and cognitive function have received increasing attention. However, the dose-response association between tooth loss and cognitive impairment remains incompletely understood. Obje...

GPNMB interacts with SMAD4 to mediate microglial neuroinflammation and induce demyelination in diabetic cognitive dysfunction

Abstract Background Diabetic cognitive dysfunction (DCD) is a prevalent hyperglycaemia-induced central nervous system complication driven by hippocampal neuroinflammation. Glycoprotein non-metastatic melanoma protein B (GPNMB) exerts anti-inflammatory neuroprotection in neurodege...

Exploring artificial intelligence usage preferences among medical students in Iran: a cross-sectional study

Abstract Artificial intelligence (AI) is increasingly integrated into medical education, offering opportunities to enhance learning, research, and clinical preparation. Although previous studies have explored medical students’ attitudes and acceptance of AI, evidence regarding th...

Trajectories of physical activity following digital education and exercise therapy—a longitudinal registry study among 15,197 persons with knee or hip osteoarthritis

Abstract Objective This study examined trajectories of physical activity (PA) and associated factors among individuals with knee or hip osteoarthritis (OA) participating in a digital education and exercise therapy program. We additionally compared patterns of patient-reported out...

A method quantifying soil melanin to understand fungal impacts on soil carbon stability

Abstract Fungal necromass, particularly dead microbial cells rich in melanin, is an important contributor to long-term soil carbon stabilization. Progress in understanding the role of soil melanin is limited by the lack of validated analytical methods. DNA-based approaches estima...

Collaboration for Environmental Evidence Critical Appraisal Tool: A tool to assess risk of bias in environmental studies estimating causal effects

Abstract Risk-of-bias assessment (also known as the critical appraisal of internal validity) is a required component of systematic reviews. It evaluates how susceptible individual primary studies are to bias at the level of each effect estimate. The assessment results are then us...

A novel ATP7A splice‑site variant with suspected maternal gonadal mosaicism in Menkes disease: functional validation and prenatal diagnosis

Abstract Menkes disease (MIM#309400) is a rare, fatal X-linked neurodegenerative disorder caused by ATP7A mutations. Delayed diagnosis due to clinical heterogeneity and limited data on mutational spectrum and reproductive risk remain challenges, with gonadal mosaicism being an of...

Chromosome-level genome assembly of a deep-sea fish Lycenchelys sp. HM-2022

Deep-sea fishes provide valuable resources for investigating vertebrate adaptation to extreme marine environments. Here, we present a chromosome-level genome assembly for a new deep-sea eelpout Lycenchelys sp. HM-2022 (Perciformes: Zoarcidae). The genome was assembled using PacBi...

Macro‑mesoscopic mechanical response of deformation‑induced disasters in deep coal‑rock structures

Abstract Deep large-section coal-rock chambers are prone to deformation and instability disasters induced by composite structural effects. To reveal the surrounding-rock deformation-failure mechanism of deep coal-rock chambers, this paper performs a dual-scale comparative study o...

Factors associated with health service utilisation in rural Victoria: a multilevel analysis informed by Andersen’s behavioral model

Abstract Background Access to health services in rural areas can be hampered by a variety of factors contributing to reduced utilisation and poorer health outcomes. Andersen’s behavioral model was developed to understand how people utilise health services by assessing association...

An intersection of machine learning and advanced econometric techniques to analyse sustainable development in Europe through resource efficiency, institutional quality, and ICT

Abstract Sustainable development is a critical challenge as well as an opportunity for modern economies, especially for European countries, where technological and institutional frameworks are increasingly evolving and reshaping. This prospective study investigates the role of re...

Seismic performance of externally stiffened ring connections between concrete-filled steel tubular columns and reinforced concrete beams

Abstract Concrete-filled steel tubular (CFST) columns are widely used in high-rise and long-span structures due to their high strength, stiffness, and ductility. However, conventional CFST column–reinforced concrete (RC) beam connections usually involve complex detailing, column...

β3‑adrenergic receptor agonist improves recovery after volumetric muscle loss and is associated with increased intramuscular brown/beige adipogenic activity in mice

Abstract Background Volumetric muscle loss (VML) often results in chronic muscle weakness, limb dysfunction, and even permanent disability. Current research primarily focuses on cell and extracellular matrix transplantation, but there is a lack of studies on the physiologically s...

Sparse Electromagnetic-Compatibility Flexible Electrodes for High-Accuracy, Fast-Recognition Human–Computer Interfaces

Surface electromyography (sEMG) gesture recognition technology offers significant potential for enhancing human-computer interaction and rehabilitation engineering by providing an intuitive and noninvasive method of engagement. However, challenges such as electromagnetic interfer...
