Efforts towards a low-temperature-sensitive physics package for vapor cell atomic clocks
Satellite Navigation, 2020 Strong environmental dependence is an intractable problem for vapor cell clocks, for which the high-temperature sensitivity of the physics package is considered one of the dominant reasons.

GNSS rapid precise point positioning enhanced by low Earth orbit satellites
Satellite Navigation, 2023 The Low Earth Orbit (LEO) satellites can be used to effectively speed up Precise Point Positioning (PPP) convergence. In this study, 180 LEO satellites with a global distribution are simulated to evaluate their contribution to the PPP convergence.

Applied Sciences, 2021 The self-comparison method is a powerful tool in the uncertainty evaluation of optical lattice clocks, but any drifts will cause a frequency offset between the two compared clock loops and thus lead to incorrect measurement result.

A time for atlases and atlases for time [PDF]
Frontiers in Systems Neuroscience, 2010 Advances in neuroanatomy and computational power are leading to the construction of new digital brain atlases. Atlases are rising as indispensable tools for comparing anatomical data as well as being stimulators of new hypotheses and experimental designs. Brain atlases describe nervous systems which are inherently plastic and variable. Thus, the levels

Time perception: Brain time or event time? [PDF]
Current Biology, 2001 Recent experiments show that synchronous events can appear to an observer to occur at different times. Neural processing time delays are offered as an explanation of these temporal illusions, but equating perceived time with processing time leads to some thorny philosophical problems.

Improved Conflict Detection for Graph Transformation with Attributes [PDF]
Electronic Proceedings in Theoretical Computer Science, 2015 In graph transformation, a conflict describes a situation where two alternative transformations cannot be arbitrarily serialized. When enriching graphs with attributes, existing conflict detection techniques typically report a conflict whenever at least ...
