Coherent receiver employing nonlinear coherence detection for carrier tracking [PDF]
, 1974 The concept of nonlinear coherence employed in carrier tracking to improve telecommunications efficiency is disclosed. A generic tracking loop for a coherent receiver is shown having seven principle feedback signals which may be selectively added and ...

Attitude Determination from Single-Antenna Carrier-Phase Measurements
, 2002 A model of carrier phase measurement (as carried out by a satellite navigation receiver) is formulated based on electromagnetic theory. The model shows that the phase of the open-circuit voltage induced in the receiver antenna with respect to a local ...

Reliable Carrier Phase Positioning [PDF]
, 2010 This work provides new algorithms for carrier phase positioning with Global Navigation Satellite Systems such as Galileo or GPS. The carrier phase can be tracked with millimeter accuracy but it is periodic. The reliability of the resolution of these carrier phase integer ambiguities is substantially improved by new multi-frequency mixed code carrier ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Effect of liquid droplets on turbulence in a round gaseous jet [PDF]
The main objective of this investigation is to develop a two-equation turbulence model for dilute vaporizing sprays or in general for dispersed two-phase flows including the effects of phase changes.

PICALM::MLLT10 translocated leukemia
FEBS Letters, EarlyView.This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...

Improvement of Carrier Phase Tracking Based on a Joint Vector Architecture
International Journal of Aerospace Engineering, 2017 Carrier phase measurements are essential to high precision positioning. Usually, the carrier phase measurements are generated from the phase lock loop in a conventional Global Navigation Satellite System (GNSS) receiver.

Phase Extraction Algorithm Based on the Spatial Carrier-Frequency Phase-Shifting Gradient
IEEE Photonics Journal, 2019 For improving the accuracy and processing speed of phase extraction, a new phase extraction algorithm based on the spatial carrier-frequency phase-shifting gradient (SCFPS-G) is proposed.

Carrier-envelope-phase-dependent dissociation of hydrogen
New Journal of Physics, 2013 We studied dependence of dissociative ionization in H2 on carrier-envelope phase (CEP) of few-cycle (6fs) near-infrared (NIR) laser pulses. For low-energy channels, we present the first experimental observation of CEP dependence for total dissociation yield and the highest dwgree of asymmetry reported to date (40%).
