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 ...

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate

Chemistry – A European Journal, EarlyView.
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Enabling Cross‐Coupling Reactivity of α‐Pentafluorosulfanyl Compounds with a Thermally Stable Organozinc α‐SF5 Reagent

Chemistry – A European Journal, EarlyView.
This work describes the first example of a thermally stable α‐SF5 organometallic reagent, which allows for extensive downstream functionalization by allylation and acylation reactions under copper catalysis, as well as palladium‐catalyzed Negishi‐type cross‐coupling conditions up to 96% yield. In silico analysis shines initial light on the requirements

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.

Systematic Turbo-Polar, Turbo-LDPC-Polar and Turbo-LDPC Codes Based on Belief Propagation Decoding

IEEE Vehicular Technology Conference
In this paper, we propose the Turbo principle (of using parallel concatenated channel encoders separated by an interleaver and iterative soft-input and soft-output decoding between the constituent decoders) onto Polar and LDPC codes resulting in Turbo ...

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

Does AI at Work Increase Stress? Text Mining Social Media About Human–AI Team Processes and AI Control

Journal of Organizational Behavior, EarlyView.
ABSTRACT With rising use of artificial intelligence (AI) in organizations, alongside increasing mental health issues, we seek to understand how AI use affects human stress. Drawing on the automation–augmentation perspective, we propose that AI control over decision‐making thwarts human autonomy and thus contributes to stress.
