Seasonality and spatial variability of dynamic precipitation controls on the Tibetan Plateau [PDF]

open access: yesEarth System Dynamics, 2016
Abstract. The Tibetan Plateau (TP) is the origin of many large Asian rivers, which provide moisture for large regions in South and East Asia. Therefore, the water cycle on the TP and adjacent high mountain ranges and especially the precipitation distribution plays an important role for the water availability for billions of people in the regions ...

A Matter of Balance: Motor Control is Related to Children’s Spatial and Proportional Reasoning Skills

open access: yesFrontiers in Psychology, 2016
Recent research has shown close links between spatial and mathematical thinking and between spatial abilities and motor skills. However, longitudinal research examining the relations between motor, spatial, and mathematical skills is rare, and the nature

A control structure for ambidextrous robot arm based on Multiple Adaptive Neuro‐Fuzzy Inference System

open access: yesIET Control Theory & Applications, 2021
This paper presents the novel design of an ambidextrous robot arm that offers double range of motion as compared to dexterous arms. The arm is unique in terms of design (ambidextrous feature), actuation (use of two different actuators simultaneously ...

A combined model reference adaptive control law for multirotor UAVs

open access: yesIET Control Theory & Applications, 2021
Model reference adaptive control (MRAC) offers the potential to adapt in real‐time to changes in the performance of small unmanned air vehicles. There are significant challenges with their use, however, primarily in the implementation and assurance of ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
