Quantitative Evaluation of Mechanical Defects for Circuit Breakers Based on Self‐Adaptive Fault Feature Tracking

High Voltage, EarlyView.
ABSTRACT Many researchers are committed to improving the diagnosis accuracy and solving the few‐shot problem on circuit breakers (CBs). However, the research on the vibration transmission mechanism of the fault is insufficient, which makes it difficult to find the potential design defects of CBs through vibration.

AllergoOncology in Review: Harnessing Allergy in the Field of Oncology to Improve Patient Outcomes

Clinical &Experimental Allergy, EarlyView.
ABSTRACT The AllergoOncology field brings together the study of allergic and cancer immune responses, having evolved from early epidemiological studies that reported inverse associations between allergies, IgE and cancer risk. Insights from studying allergic inflammation are revealing previously unappreciated immune mechanisms that confer protective ...

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.
