Semi-Supervised Gearbox Anomaly Detection Under Variable Operating Conditions

Feature distributions shift under variable-speed gearbox operation, which can cause a model trained only on healthy samples to misclassify normal operating changes as anomalies. A semi-supervised anomaly detection method is proposed in this study. Using healthy data, the method f...

Anesthetic management for bronchoscopic intervention in a patient with mucopolysaccharidosis and short stature complicated by mediastinal mass-induced airway stenosis: a case report

Mucopolysaccharidosis (MPS) is a group of inherited lysosomal storage disorders associated with difficult airway management. Critical tracheal compression from an anterior mediastinal mass presents an additional challenge during interventional bronchoscopy, when the airway is sha...
