What makes soccer fun? Investigating fun priorities among Swedish adolescents by gender, age, perceived competence, and sports program type

Lack of fun has been described as a prominent reason for dropping out of soccer. Hence, understanding what makes soccer fun is critical to promoting continued participation. Efforts to facilitate fun experiences require insight into adolescents’ priorities regarding what constitu...

Error State Kalman Filter for Integrated Attitude Estimation Based on Data Fusion of MIMU Inertial Array and Magnetometer

Attitude estimation has increasingly relied on MEMS inertial measurement units (IMUs) owing to the low cost and miniature size, but the inherent high random noise and error accumulation limit long-term measurement accuracy. This article proposes an integrated attitude estimation...

Reusable and Soft Self-Adhesive Epidermal Electrodes for Human Skin Enabled by Functional Additives

Wearable electronics, particularly dry epidermal electrodes, provide human-connected interfaces for recording biopotential signals. However, their practical utility is often hindered by their limited operational longevity and the resulting environmental burden of electronic waste...

Freeriding and Rebellion: An Investigation of Open Source Vendor Relicensing and Member Hard Forking Events

ABSTRACT Open source engagement is an ongoing effort in which members continuously interact with evolving project dynamics. Engagement extends beyond writing code or setting policy; it is a shared practice of understanding, negotiating, and adapting to the social and technical st...

Calibration Robustness and Cross-Device Transferability of Four Temperature-Sensitive Electrical Parameters in Enhancement-Mode GaN HEMTs

Reliable temperature estimation in GaN high-electron-mobility transistors requires temperature-sensitive electrical parameters (TSEPs) that combine sufficient sensitivity with stable calibration behavior. This study compares on-state resistance (Rds(on)), threshold voltage (Vth),...

Adaptive Knowledge Fusion via Dynamic Stacking for Surrogate-Assisted Transfer Optimization

The integration of transfer learning with surrogate-assisted optimization represents a highly promising paradigm for complex engineering problems. However, it is fundamentally constrained by insufficient cross-domain adaptation and the absence of robust knowledge-fusion technique...

Machine Learning-Assisted Design Optimization of CdS/Zn(O,S) Window Layer CdTe Solar Cells Using SCAPS-1D

Abstract Cadmium telluride (CdTe) is a scalable, high-absorption thin-film photovoltaic technology, but a trade-off at the front interface limits its efficiency. Thinner CdS window layers cut parasitic short-wavelength absorption, while rough commercial substrates need a thick wi...

Redefining Carbon Electrodes as Hierarchically Designable Reaction Fields for Electrochemical Biosensing

Electrochemical biosensors based on carbon materials have achieved remarkable sensitivity, yet carbon electrodes are still often treated as black-box conductive supports. In this perspective, we redefine carbon materials as hierarchically designable reaction fields in which defec...

Camellia nitidissima Flower Extract Alleviates Stress-Induced Sebaceous Dysfunction by Targeting the 11β-HSD1/PI3K/Akt/mTOR Axis

Stress-induced sebaceous hyperactivity is a key driver of acne and seborrheic dermatitis; however, research investigating the pathway-specific mechanisms through which stress exerts its effects and the suppression of sebum production via targeting stress signaling remains relativ...

Leadership to strengthen research culture and foster responsible conduct of research: A case study

OBJECTIVE: Research performing organizations (RPOs) are increasingly expected to strengthen research culture and support the responsible conduct of research (RCR). Institutional supports are central to advancing research culture across RPOs. To inform development and evaluation o...

Phytochemistry, Chemotypic Diversity and Antimicrobial Potential of Essential Oils From Native Aromatic Plants of the Americas: A Systematic Review

ABSTRACT Essential oils (EOs) derived from native aromatic plants represent a critical frontier for sustainable development, biodiversity conservation and innovative pharmacological applications in the Americas. This review synthesizes current scientific knowledge on the chemical...

E8 Phi-Chronosync Resonance Cascade — E8 Intelligence Research

By superimposing the 240 E8 root vectors across phi-scaled 132 Hz standing wave clusters we identify a cascading resonance mechanism we term Phi-Chronosync. Unlike static Phi-Chronon phases this cascade exploits sequential constructive interference where each root vector's phi-of...

Geospatial Analysis of Traditional Medicine Utilization in Post Covid-19 Nigeria: Patterns, Determinants, and Policy Implications

The COVID-19 pandemic significantly altered healthcare-seeking behaviour across the globe, leading to renewed reliance on traditional medicine, particularly in developing countries where access to conventional healthcare was disrupted. In Nigeria, traditional medicine became an i...

Trends in Hospitalization, Case Fatality, and Mortality for Community-Acquired Pneumonia in Portugal over 20 Years

Background: Community-acquired pneumonia (CAP) remains a leading cause of morbidity and mortality worldwide and a major driver of hospital admissions. Older adults are disproportionately affected, owing to immune senescence and a higher prevalence of chronic comorbidities. This s...

Study on the Mix Design of Mastic Flow for Filling Based on Deviation Coefficient Method

To quantitatively evaluate the skeleton design of the MaFF method, this study addresses five dimensions: gradation control, test method, quantitative model, correction conversion, and design method. First, the deviation coefficient method is proposed based on the Talbot method. U...

Multiple-use prediction and calibration for all future values: Exact simultaneous tolerance bands for multiple and polynomial regressions

Multiple-use prediction and calibration for all future values play an important role in many areas, including health and medical research. Simultaneous tolerance bands (STBs) can be employed for these purposes. This article studies the construction of exact STBs for multiple regr...

Increased receptor binding and spike glycosylation, remodeled immune escape of surging SARS-CoV-2 subvariant BA.3.2.2/RE.2.2/Cicada

SARS-CoV-2 continues to evolve. The subvariant BA.3.2 (Cicada), a derivative of the Omicron BA.3 subtype first detected in late 2024, harbors multiple spike protein mutations, ORF7 and ORF8 deletions, and has recently evolved sublineages (BA.3.2.1 and BA.3.2.2), rendering it a cr...

Stakeholder-informed pre-implementation refinement of a pharmacy-led pre-exposure prophylaxis (PrEP) service delivery model in Malaysia

Introduction In 2024, only 3,451 individuals accessed free oral HIV pre-exposure prophylaxis (PrEP) at government clinics in Malaysia, despite an estimated 354,000 key population members who could benefit from PrEP. To inform pre-implementation refinement of a pharmacy-led PrEP s...

Host Plant Biochemical Influence on the Foraging and Food Utilization of Poecilocerus pictus and Danaus chrysippus on Calotropis gigantea: A Behavioral Ecology Approach

Poecilocerus pictus and Danaus chrysippus are two common herbivorous insects that share the same host plant, Calotropis gigantea, yet they exhibit distinct feeding preferences and food utilization patterns across leaf ages. D. chrysippus larvae performed better on young leaves, w...

Rearticulation Without Ontological Separation: Claim\-Safe Continuity Under Changing Representations, Meanings, and Provenance

We study a reconstruction problem in which not only represented content but the representational scheme, relevance structure, and semantic resolution may change. The framework treats counting as articulation-relative, distinguishes missing articulation from negation, uses proof-r...
