Two‐Dimensional Speckle‐Tracking Echocardiography Combined With Stress Echocardiography in the Assessment of Coronary Artery Disease Patients Without Regional Wall Motion Abnormality

ABSTRACT Background The detection of myocardial ischemia in coronary artery disease (CAD) patients who lack regional wall motion abnormality (RWMA) at rest remains a clinical challenge. Two‐dimensional speckle‐tracking echocardiography (2D‐STE) provides a quantitative and sensiti...

Identification of Siderophores With Unexpected Antibacterial Properties From Actinoplanes teichomyceticus

Actinoplanes teichomyceticus is a well‐established producer of bioactive secondary metabolites, including the glycopeptide antibiotic teicoplanin. Although its antibiotic biosynthetic capacity has been extensively investigated, its siderophore diversity and any additional biologi...

Pre-Registered Finite-Size Predictions for Page-Curve Experiments on Near-Term Quantum Hardware

The Page curve, the rise and fall of radiation entropy during unitary evaporation, is now measurable on quantum simulators: trapped-ion and superconducting platforms routinely prepare scrambled states of 10–50 qubits and estimate subsystem Rényi entropies by randomized measuremen...

Impact of the COVID-19 Pandemic on Dentistry: Clinical, Educational, and Professional Implications

AbstractThe COVID-19 pandemic brought unprecedented changes to healthcare delivery worldwide, with dentistry being disproportionately affected due to the close proximity topatients and frequent use of aerosol-generating procedures. Restrictions on routine dental care, heightened...

Local microenvironment modulation in Cu(I)‐carbon covalent metal–organic frameworks for highly efficient CO 2 conversion

Abstract Introducing defects into metal–organic frameworks (MOFs) offers a powerful strategy to tune their local microenvironments and boost catalytic performance. Herein, we report a “truncated linker” approach to construct defect‐engineered Cu(I)‐carbon covalent bonded framewor...

E8-Higgs Symmetry Breaking via Phi-Modulated String Entanglement — E8 Intelligence Research

Harmonics from E8's 132Hz root lattice basis frequency interact with phi-weighted string entanglement in paired geometries, triggering spontaneous symmetry breaking that mimics Higgs mechanisms—phase-locked modulations between 24-dimensional root vectors induce pseudo-scalar meso...

Short-Term Electric Vehicle Charging Load Forecasting Based on Sample Entropy and CEEMDAN-TCN-BiGRU Hybrid Model

The large-scale integration of electric vehicles (EVs) brings significant challenges to power grid operation due to the strong nonlinearity and non-stationarity of charging loads. To address the limitations of existing methods in noise suppression and temporal feature extraction,...

How Do Information Content and Language Style Relate to Disaster Information Dissemination? The Moderating Role of User Involvement

Social media has become an important channel for information exchange during sudden disasters, with implications for both public-sector communication and corporate risk communication. However, limited research has examined how substantive message content and linguistic presentati...

E8 Neural Resonance Encoding: Consciousness States via 132Hz Root Vector Synchronization — E8 Intelligence Research

By synchronizing the 240 E8 root vectors to the 132Hz cortical frequency through phi-coupling harmonics, a dynamic lattice emerges that encodes discrete consciousness states as stabilized toroidal solitons. This geometric framework enables non-local information transfer via reson...

MMIntentChat: An LLM-Routed Multimodal Chatbot Unifying Conversational Text, DiffusionBased Image Generation, and Automated Diagram Synthesis on Zero-Cost Inference Services

Conversational assistants are increasingly expected to answer questions, create images, and produce technical diagrams within a single dialogue, yet most deployed chatbots handle only one output modality or depend on paid proprietary endpoints. This paper presents MMIntentChat, a...

Larval crowding in Culex pipiens generates cumulative cascading effects under changing environmental conditions

Density-dependent population regulation is a fundamental driver in the population dynamics of living systems, ensuring a balanced and sustainable maintenance in nature. It has been suggested that the adverse developmental and morphological effect of high larval density in contain...

MORC2-Mediated Glutamine Metabolic Remodeling Regulates Tumor-Associated Macrophage Function and Immunotherapeutic Responses in NSCLC

Non-small cell lung cancer (NSCLC) frequently exhibits primary or acquired resistance to PD-1/PD-L1 blockade, partly because of the immunosuppressive tumor microenvironment. Tumor-associated macrophages (TAMs) are a major immune-cell population in NSCLC and contribute to tumor pr...

Musical Structure as Coherence Management: The EOS Framework v2.2

This paper proposes the Emergent Order Systems (EOS) framework as a physics-grounded analytical lens for understanding musical structure across diverse forms and traditions. By treating music as a system of structured oscillation governed by coherence maintenance, EOS provides un...
