We present several equivalent conditions for C-finitely correlated states defined on the UHF algebras to be factor states and consider the types of factors generated by them. Subfactors generated by generalized quantum Markov chains defined on the gauge-invariant parts of the UHF algebras are also discussed.

Paper presents a method for analysis of UHF RFID tags. After a brief overview of RFID system and UHF tags an electromagnetic (EM) simulation of tags in WIPL-D software was conducted. Electrical matching was performed after which tags were excited by a uniform EM wave, induced powers were measured and tag characteristics were compared.

PURPOSE This study examines the subjective acceptance during UHF-CMR in a cohort of healthy volunteers who underwent a cardiac MR examination at 7.0T. METHODS Within a period of two-and-a-half years (January 2012 to June 2014) a total of 165 healthy volunteers (41 female, 124 male) without any known history of cardiac disease underwent UHF-CMR. For the assessment of the subjective acceptance ...

We certify that this work has passed the scholastic standards requested by the Information and Communications University as a thesis for the Abstract The commercialization of Ultra-WideBand (UWB) ranging from 3.1-10.6 GHz by Federal Communication Commission (FCC) has recently emerged as a promising technology for short-range wireless data communications. The applications of wireless data commun...

Diffusion kurtosis has become an important magnetic resonance imaging (MRI) modality for non-invasively mapping the microstructural variations in living tissues. Theoretically, spatial resolution of diffusion (DKI) can be significantly improved by acquiring data at ultra-high fields (UHF, ≤ 7 Tesla) because increased signal-to-noise ratios. However, issues such as susceptibility artefacts and r...

Background As shown at 7T Time-of-Flight (TOF) angiography significantly benefits from ultra high field (UHF) [1,2], because of shorter T1 relaxation constant and increased SNR. However, significant challenges have to be overcome before using 7T TOF in clinical applications: I) RF induced specific absorption rate (SAR) substantially increases at UHF, preventing the use of standard RF pulses (ve...

Many vertebrates communicate with ultrahigh frequency (UHF) vocalizations to limit auditory detection by predators. The mechanisms underlying the neural encoding of such UHF sounds may provide important insights for understanding neural processing of other complex sounds (e.g. human speeches). In the auditory system, sound frequency is normally encoded topographically as tonotopy, which, howeve...

Recently, radio frequency identification (RFID) have created emerging applications for tracking, sensing, and identifying various targets in wide-ranging areas such as supply chain, transportation, airline baggage handling, medical and biological industry, and homeland security. RFID systems with a variety of radio frequencies and techniques have been introduced. Among them, ultra-high frequenc...
