Current Concepts of Pathophysiology of Vasovagal Syncope and its Evaluation and Management: A Review
Annals of the National Academy of Medical Sciences (India), 2018 Vasovagal syncope (VVS) with a sudden, temporary loss of consciousness (LoC) is a common phenomenon in the young and the elderly. Though generally described as innocuous, it may lead to serious consequences in special category of people (pilots), or in ...

Contention-based Grant-free Transmission with Independent Multi-pilot Scheme [PDF]
arXiv, 2020 Contention-based grant-free transmission is very promising for future massive machine-type communication (mMTC). In contention-based transmission, the random pilot collision is a challenging problem. To solve this problem, multiple pilots scheme is used to reduce the pilot collision probabliltiy.

Joint Pilot Design and Uplink Power Allocation in Multi-Cell Massive MIMO Systems [PDF]
arXiv, 2017 This paper considers pilot design to mitigate pilot contamination and provide good service for everyone in multi-cell Massive multiple input multiple output (MIMO) systems. Instead of modeling the pilot design as a combinatorial assignment problem, as in prior works, we express the pilot signals using a pilot basis and treat the associated power ...

Spectral and Energy Efficiency of Superimposed Pilots in Uplink Massive MIMO [PDF]
arXiv, 2017 Next generation wireless networks aim at providing substantial improvements in spectral efficiency (SE) and energy efficiency (EE). Massive MIMO has been proved to be a viable technology to achieve these goals by spatially multiplexing several users using many base station (BS) antennas.

A Comprehensive Perspective on Pilot-Job Systems [PDF]
arXiv, 2015 Pilot-Job systems play an important role in supporting distributed scientific computing. They are used to consume more than 700 million CPU hours a year by the Open Science Grid communities, and by processing up to 1 million jobs a day for the ATLAS experiment on the Worldwide LHC Computing Grid. With the increasing importance of task-level parallelism

Enhanced Channel Estimation in Massive MIMO via Coordinated Pilot Design [PDF]
arXiv, 2019 Pilot contamination is a limiting factor in multicell massive multiple-input multiple-output (MIMO) systems because it can severely impair channel estimation. Prior works have suggested coordinating pilot design across cells in order to reduce the channel estimation error caused by pilot contamination. In this paper, we propose a method for coordinated

A reflexive exploration of two qualitative data coding techniques
Journal of Methods and Measurement in the Social Sciences, 2015 In an attempt to help find meaning within qualitative data, researchers commonly start by coding their data. There are a number of coding systems available to researchers and this reflexive account explores my reflections on the use of two such ...
