Near-surface wind characteristics of extreme thunderstorm outflows
TL;DR: In this paper, a large-scale experiment was conducted in 2002, during which seven mobile towers were deployed in a linear array to obtain high-resolution data from outflows and two extreme events were captured: a rear-flank downdraft of a supercell, and a derecho.

TL;DR: A long short-term memory (LSTM) network is proposed as a solution to model long-term cardiac sleep architecture information and validated on a comprehensive data set, demonstrating the merit of deep temporal modelling using a diverse data set and advancing the state-of-the-art for HRV-based sleep stage classification.

Long-term trends of surface ozone and its influencing factors at the Mt Waliguan GAW station, China – Part 1: Overall trends and characteristics
TL;DR: Wang et al. as discussed by the authors performed the Mann-Kendall trend test and the Hilbert-Huang transform (HHT) analysis on the ozone data, which revealed that the mountain-valley breeze plays an important role in the diurnal cycle of surface ozone at Waliguan, resulting in higher ozone values during the night and lower ones during the day.

Early chatter identification based on an optimized variational mode decomposition
TL;DR: In this article, the authors developed a method of online chatter identification for milling processes, where optimized variational mode decomposition (OVMD) is used to decompose cutting force measurements, and the sub-components containing chatter information are extracted using a simulated annealing (SA) algorithm.

An integrated GPS-accelerometer data processing technique for structural deformation monitoring
TL;DR: The proposed data processing techniques can significantly enhance the measurement accuracy of the total displacement of a structure and are compared with the actual displacement motions generated by the motion simulation table.

Deterministic nonperiodic flow
TL;DR: In this paper, it was shown that nonperiodic solutions are ordinarily unstable with respect to small modifications, so that slightly differing initial states can evolve into considerably different states, and systems with bounded solutions are shown to possess bounded numerical solutions.
