Temporal Variability of Cortical Gyral-Sulcal Resting State Functional Activity Correlates With Fluid Intelligence

Frontiers in Neural Circuits, 2019
The human cerebral cortex is highly convoluted as convex gyri and concave sulci. In the past decades, extensive studies have consistently revealed substantial differences between gyri and sulci in terms of genetics, anatomy, morphology, axonal fiber ...

Rapid Bioassessment Protocols Using Aquatic Macroinvertebrates in Africa–Considerations for Regional Adaptation of Existing Biotic Indices

Frontiers in Water, 2021
Benthic macroinvertebrates are commonly used to assess water quality and ecological condition of aquatic ecosystems and they form the basis of several biotic indices. Many of these biotic indices are based on rapid bioassessment protocols (RBP).

New perspectives in human movement variability [PDF]

, 2013
Movement variability is defined as the normal variations that occur in motor performance across multiple repetitions of a task.2 Bernstein1 described movement variability quite eloquently as ‘‘repetition without repetition.’’ Traditionally, movement ...

Multi-Scale Entropy Analysis as a Method for Time-Series Analysis of Climate Data [PDF]

, 2015
Evidence is mounting that the temporal dynamics of the climate system are changing at the same time as the average global temperature is increasing due to multiple climate forcings.

Extraction of Concealed Features From RF-EMF Monitoring at Kindergartens and Schools

IEEE Access
Modern electromagnetic field (EMF) monitoring networks, such as the Serbian EMF RATEL network, are based on continuous EMF monitoring and offer daily observation of EMF levels in areas where people can reside for many hours a day and, consequently ...

Effects of the Temporal Variability of Storm Surges on Coastal Flooding

Frontiers in Marine Science, 2020
Assessments of flood exposure and risk are usually conducted for individual events with a specific peak water level and hydrograph, without considering variations in the temporal evolution (duration and intensity) of storm surges. Here we investigate the

Near-Infrared Spectroscopy (NIRS) and Optical Sensors for Estimating Protein and Fiber in Dryland Mediterranean Pastures

AgriEngineering, 2021
Dryland pastures provide the basis for animal sustenance in extensive production systems in Iberian Peninsula. These systems have temporal and spatial variability of pasture quality resulting from the diversity of soil fertility and pasture floristic ...

Dual-Task Interference Increases Variability in Sub-Second Repetitive Motor Timing

Journal of Functional Morphology and Kinesiology
Objectives: Sub-second motor timing is critical for skilled performance in domains such as sport, music, and safety-critical multitasking; however, its robustness under cognitive load remains unresolved. Dual-task paradigms offer a method to test whether
