ABSTRACT In children with complete unilateral main bronchial obstruction from foreign body aspiration, positive pressure ventilation may overdistend the contralateral ventilated lung, leading to barotrauma and tension pneumothorax. Sudden hypoxemia and hypotension should prompt rapid clinical assessment, including lung ultrasound, and immediate ...

This study employs an interpretable machine learning framework to predict diabetes‐cancer comorbidity, with the Random Forest and LightGBM models demonstrating exceptional performance. SHAP value analysis reveals that while advanced age and cardiometabolic dysfunctions serve as primary risk drivers, dietary antioxidants (particularly daidzein and ...

ABSTRACT Rapid advances in microbiome research are transforming our understanding of human health and disease, with growing focus on the female reproductive tract as a critical but understudied niche. Evidence for a local microbiome largely derives from bacterial nucleic acid detection; however, the biological relevance of these signals remains debated,

Surge Arrester Protection and Very Fast Surges
IEEE Power Engineering Review, 1983The results of this paper suggest that surge arrester protection may not be adequate for very fast rates of rise of lightning currents even considering insulation strength greater than chopped-wave. Additionally, it is shown that prediction of the magnitude and front time of the peak overvoltage is a complex function of lead length, arrester model ...

IEEE Transactions on Electrical Insulation, 1986
The MOSA (Metal Oxide Surge Arrestor) comprising ZnO non-linear elements has been taking the place of the conventional gapped arresters on a world-wide scale. The ZnO non-linear element was developed in Japan and the application for the surge arrester was also established in Japan for the first time.

Evaluation of Surge Degradation of Metal Oxide Surge Arrester
IEEE Transactions on Power Apparatus and Systems, 1982The surge degradation of zinc oxide elements under a constant ac stress is investigated experimentally. The results are summed up in a set of formulae and figures from which the degradation of any given condition can be evaluated. The increase ratio of leakage current from the initial value is successfully sed as the indicator of degradation of ...

Development Of A Non-Fragmenting Distribution Surge Arrester
IEEE Transactions on Power Apparatus and Systems, 1984Failure of a distribution surge arrester can result in fracturing of the porcelain housing. Although the probability of an arrester failure is extremely low, the cumulative number of failures could be substantial because of the large number of arresters installed.
