Plastic Properties of Prestressed High-Strength Steel Reinforced Concrete Continuous Beams

Applied Sciences
In this paper, the plastic properties of prestressed high-strength steel reinforced concrete (PHSSRC) beams are studied, by performing static load tests on eight built-in Q460 and Q690 prestressed high-strength steel reinforced concrete continuous beams ...

Effects of Carpal Tunnel Syndrome on adaptation of multi-digit forces to object mass distribution for whole-hand manipulation

Journal of NeuroEngineering and Rehabilitation, 2012
Background Carpal tunnel syndrome (CTS) is a compression neuropathy of the median nerve that results in sensorimotor deficits in the hand. Until recently, the effects of CTS on hand function have been studied using mostly two-digit grip tasks.

Moment-Based Approach for Statistical and Simulative Analysis of Turbulent Atmospheric Channels in FSO Communication

IEEE Access, 2019
The free space optical (FSO) or wireless optical communication networks involve atmosphere as the channel, which at times can be turbulent in nature, thus degrading the system performance.

Manual action verbs modulate the grip force of each hand in unimanual or symmetrical bimanual tasks. [PDF]

PLoS ONE, 2018
Manual action verbs modulate the right-hand grip force in right-handed subjects. However, to our knowledge, no studies demonstrate the ability to accomplish this modulation during bimanual tasks nor describe their effect on left-hand behavior in ...

Automatic Modulation Classification for MASK, MPSK, and MQAM Signals Based on Hierarchical Self-Organizing Map

Sensors, 2022
Automatic modulation classification (AMC) plays a fundamental role in common communication systems. Existing clustering models typically handle fewer modulation types with lower classification accuracies and more computational resources.

Approximate symbol error rate of cooperative communication over generalised κ−μ and η−μ fading channels

The Journal of Engineering, 2014
Closed form expressions for approximate symbol error rate are obtained using moment generating function for a two branch cooperative communication system over generalised κ−μ and η−μ i.i.d. fading channels for BPSK and QAM modulation schemes.

Modulation of brain signal variability in visual cortex reflects aging, GABA, and behavior

eLife
Moment-to-moment neural variability has been shown to scale positively with the complexity of stimulus input. However, the mechanisms underlying the ability to align variability to input complexity are unknown.
