In the determination of.the Earth gravity f.eld in satellite geodesy, the inclination f.nctions represent the projection of.data observed along the orbital plane of.a satellite orbit into the sphere in the terrestial ref.rence f.ame. The inclination f.nctions in this work is studied f.om a group theoretical perspective. The inclination f.nctions are proved to generate a representation of.the SO(3) group. An orthogonal relation of.the inclination f.nctions is derived and some recurrence relations f.r the inclination f.nctions are given, based on which an algorithm to calculate the inclination f.nctions is proposed.

Organic electrochemical transistors(OECTs) exhibit signif.cant potential f.r applications in healthcare and human-machine interf.ces, due to their tunable synthesis, f.cile deposition, and excellent biocompatibility. Expanding OECTs to the f.xible devices will signif.cantly f.cilitate stable contact with the skin and enable more possible bioelectronic applications. In this work,we summarize the device physics of.f.xible OECTs, aiming to of.er a f.undational understanding and guidelines f.r material selection and device architecture. Particular attention is paid to the advanced manuf.cturing approaches, including photolithography and printing techniques, which establish a robust f.undation f.r the commercialization and large-scale f.brication. And abundantly demonstrated examples ranging f.om biosensors, artif.cial synapses/neurons, to bioinspired nervous systems are summarized to highlight the considerable prospects of.smart healthcare. In the end, the challenges and opportunities are proposed f.r f.xible OECTs. The purpose of.this review is not only to elaborate on the basic design principles of.f.xible OECTs, but also to act as a roadmap f.r f.rther exploration of.wearable OECTs in advanced bio-applications.

Aviation accidents are currently one of.the leading causes of.signif.cant injuries and deaths worldwide. This entices researchers to investigate aircraf. saf.ty using data analysis approaches based on an advanced machine learning *** assess aviation saf.ty and identif. the causes of.incidents, a classif.cation model with light gradient boosting machine (LGBM)based on the aviation saf.ty reporting system (ASRS) has been developed. It is improved by k-f.ld cross-validation with hybrid sampling model (HSCV), which may boost classif.cation perf.rmance and maintain data balance. The results show that employing the LGBM-HSCV model can signif.cantly improve accuracy while alleviating data imbalance. Vertical comparison with other cross-validation (CV) methods and lateral comparison with dif.erent f.ld times comprise the comparative approach. Aside f.om the comparison, two f.rther CV approaches based on the improved method in this study are discussed:one with a dif.erent sampling and f.lding order, and the other with more CV. According to the assessment indices with dif.erent methods, the LGBMHSCV model proposed here is ef.ective at detecting incident causes. The improved model f.r imbalanced data categorization proposed may serve as a point of.ref.rence f.r similar data processing, and the model’s accurate identif.cation of.civil aviation incident causes can assist to improve civil aviation saf.ty.
