Classification of RCS sequences based on KL divergence
The Journal of Engineering, 2019 Radar cross section (RCS) is an important characteristic of radar targets. The mean, variance, skewness, kurtosis, varying patterns of RCS sequences provide rich features for radar target classification.

The Annals of Mathematical Statistics, 1948 It is well known that, if the fourth moment about the mean of a frequency distribution equals the square of the variance, then the frequencies are piled up at exactly two points, namely, the two points that are one standard deviation away from the mean.

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1964 Summary This note “rediscovers” the original interpretation of kurtosis as an indicator of “a prominent peak and a prominent tail” on the density curve. A formal proof that such curves have indeed relatively high fourth moments is given. A comment is made concerning the recent decline of this correct classical interpretation.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Mastering the Body and Tail Shape of a Distribution
Mathematics, 2021 The normal distribution and its perturbation have left an immense mark on the statistical literature. Several generalized forms exist to model different skewness, kurtosis, and body shapes.
