A Real-Time Cycle Slip Detection and Repair Method Based on Ionospheric Delay Prediction for Undifferenced Triple-Frequency BDS Signals

IEEE Access, 2021
The detection and repair of cycle slips are key steps in high-accuracy GNSS (Global Navigation Satellite System) data processing using carrier phase observations.

Superfluidity versus Bloch oscillations in confined atomic gases

, 2001
We study the superfluid properties of (quasi) one-dimensional bosonic atom gases/liquids in traps with finite geometries in the presence of strong quantum fluctuations.

Polychromatic Optical Bloch Oscillations [PDF]

, 2009
Bloch oscillations (BOs) of polychromatic beams in circularly-curved optical waveguide arrays are smeared out owing to the dependence of the BO spatial period on wavelength.

Feasibility of precise navigation in high and low latitude regions under scintillation conditions [PDF]

, 2018
Scintillation is one of the most challenging problems in Global Navigation Satellite Systems (GNSS) navigation. This phenomenon appears when the radio signal passes through ionospheric irregularities.

Effect of reactive balance training involving repeated slips and trips on balance recovery among older adults: A blinded randomized controlled trial.

The journals of gerontology. Series A, Biological sciences and medical sciences, 2019
Background This study examined whether reactive balance training (exposures to slips and trips) could improve balance recovery and reduce perturbation-induced falls among older adults.

Strongly Localized State of a Photon at the Intersection of the Phase Slips in 2D Photonic Crystal with Low Contrast of Dielectric Constant

, 2002
Two-dimensional photonic crystal with a rectangular symmetry and low contrast (< 1) of the dielectric constant is considered. We demonstrate that, despite the {\em absence} of a bandgap, strong localization of a photon can be achieved for certain ``magic'

Phase-charge duality in Josephson junction circuits: Role of inertia and effect of microwave irradiation [PDF]

, 2009
We investigate the physics of coherent quantum phase slips in two distinct circuits containing small Josephson junctions: (i) a single junction embedded in an inductive environment and (ii) a long chain of junctions.

Management of slips and its effect on growth and production of 'Pérola' pineapple plants

Revista Brasileira de Fruticultura, 2003
The lack of good quality planting material has limited the expansion and contributed to yield reduction of the Brazilian pineapple culture. Alternatives of 'Pérola' pineapple slips management were studied aiming at obtaining superior planting material ...

Electrostatic Control of Phase Slips in Ti Josephson Nanotransistors [PDF]

Physical Review Applied, 2019
The investigation of the switching current probability distribution of a Josephson junction is a conventional tool to gain information on the phase slips dynamics as a function of the temperature.

The Effects of an Acute Exposure of Virtual vs. Real Slip and Trip Perturbations on Postural Control

Virtual Worlds
Background: Current methods of postural control assessments and interventions to improve postural stability and thereby prevent falls often fail to incorporate the hazardous perturbation situations that frequently accompany falls.
