Using gudermannian to improve the turbo-code mathematical principles in 3g communication systems

2013 International Siberian Conference on Control and Communications (SIBCON), 2013
This paper discusses the promising modern turbo-codes in the concept of 3rd generation communication systems. Presents the extended mathematical principles of the algebra logarithm of the likelihood function for N statistically independent information bits with the transition to trigonometric and hyperbolic functions by using Gudermannian expression ...

Isoform Specificity of a Compound Targeting Actin Filaments Containing Tropomyosin Tpm1.8/1.9

Cytoskeleton, EarlyView.
ABSTRACT The unbranched actin filaments in mammalian cells are usually composed of co‐polymers of a specific tropomyosin isoform with actin. Genetic manipulation has revealed that the tropomyosins largely define the functional properties of actin filaments in an isoform‐specific, non‐redundant manner.

Turbo codes and turbo algorithms

Journal of Communications Software and Systems, 2006
In the first part of this paper, several basic ideas that prompted the coming of turbo codes are commented on. We then present some personal points of view on the main advances obtained in past years on turbo coding and decoding such as the circular ...

Optimal Selection of the Effective Echo Time (TEeff) for T2‐Weighted Fast‐Spin‐Echo MRI of the Prostate at 3.0 T: Effect on Lesion Conspicuity

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Clinical T2‐weighted (T2W) MRI of prostate cancer (PCa) usually implements a 2D fast‐spin‐echo (FSE) sequence, but understanding the echo‐time‐dependent contrast behavior is not straightforward due to the complicated FSE signal evolution.

An Off-Grid Turbo Channel Estimation Algorithm for Millimeter Wave Communications

Sensors, 2016
The bandwidth shortage has motivated the exploration of the millimeter wave (mmWave) frequency spectrum for future communication networks. To compensate for the severe propagation attenuation in the mmWave band, massive antenna arrays can be adopted at ...

How Can Teams Benefit From AI Team Members? Exploring the Effect of Generative AI on Decision‐Making Processes and Decision Quality in Team–AI Collaboration

Journal of Organizational Behavior, EarlyView.
ABSTRACT Human teams with distributed knowledge can make high‐quality decisions but often fail due to decision‐making asymmetries. As AI team members become integrated collaborators, understanding how AI can reduce these decision‐making asymmetries is essential. However, little is known about how AI team members can reduce these asymmetries and whether
