Motivation: Although animals and humans navigate complex terrain in their everyday lives, the biomechanical and energetic effects on legged locomotion from uneven terrain have scarcely been quantified [1]. Most gait research has examined locomotion on smooth, level surfaces. Identifying key gait parameters that permit agile locomotion across uneven surfaces could lead to clearer understanding o...

The aim of this study was to determine the optimal cutting cycle in an uneven-aged beech forest in the North of Iran. First of all, a logistic growth model was determined for an uneven aged forest. Then, the stumpage price was predicted via an autoregressive model. The average stumpage price of beech was derived from actual timber, round wood, fire and pulpwood prices at road side minus the var...

Control of legged locomotion across uneven terrain is poorly understood from a theoretical perspective, despite strong relevance to clinical and robotic applications. Gait research has typically examined locomotion on smooth and level surfaces with uniform steps. Identifying key gait parameters that permit agile locomotion across uneven surfaces could lead to a clearer understanding of control ...

Introduction: Ina is an irregular mare patch located in the mare unit Lacus Felicitatis near 18° N and 5° E. Irregular mare patches (IMPs) are small (< 5 km across) unusual lunar features that are chacterized by topographically high, smooth deposits (or mounds) that occur with topographically low, blocky or uneven surfaces [1]. Ina (Figure 1) was first identified in Apollo images [2], and has s...

Mapping uneven events, such as disease cases or pollutants, is a basic but important procedure for analyzing regional relationships and variation in public health and environmental agencies. The purpose of mapping is to find out the spatial clustering of uneven events and identify spatial risk areas, which could lead to potential environmental hazards or epidemics. Meanwhile, more hypotheses co...
