🔬 Cross-Domain Discovery Capabilities

Enabled Discovery Patterns:

1. Earthquake-Climate Correlations

   • Link seismic events with ocean temperature anomalies
   • Detect patterns in climate data around earthquake zones

2. Materials for Detectors

   • Match particle physics detector requirements with material properties
   • Find semiconductors with optimal band gaps for sensors

3. Ocean-Particle Physics

   • Correlate ocean neutrino detection with LHC collision data
   • Cross-reference marine experiments with CERN datasets

4. Multi-Domain Anomalies

   • Simultaneous anomaly detection across physics/seismic/ocean
   • Coherence breaks spanning multiple domains

5. Materials-Seismic Applications

   • Piezoelectric materials for earthquake sensors
   • Crystal systems optimal for seismic instrumentation

📊 SemanticVector Structure

All clients convert data to consistent SemanticVector format:

SemanticVector {
    id: String,              // "USGS:123" or "CERN:456"
    embedding: Vec<f32>,     // 256-dim semantic embedding
    domain: Domain,          // Physics/Seismic/Ocean
    timestamp: DateTime<Utc>,
    metadata: HashMap<String, String>  // Source-specific fields
}

🚀 Usage Example

# Run the example
cd /home/user/ruvector/examples/data/framework

# Without API keys (USGS, CERN, Argo work)
cargo run --example physics_discovery

# With Materials Project API key
export MATERIALS_PROJECT_API_KEY="your_key_here"
cargo run --example physics_discovery

🔗 Integration Points

📦 Dependencies

All clients use existing framework dependencies:

• reqwest - HTTP client
• tokio - Async runtime
• serde / serde_json - Serialization
• chrono - Date/time handling
• SimpleEmbedder - Text embedding generation

No new dependencies required.
