Predicting the Success Rate of Long-baseline GPS+Galileo (Partial) Ambiguity Resolution [PDF]
Journal of Navigation, 2014 This contribution covers precise (cm-level) relative Global Navigation Satellite System (GNSS) positioning for which the baseline length can reach up to a few hundred km. Carrier-phase ambiguity resolution is required to obtain this high positioning accuracy within manageable observation time spans.

Real-Time GNSS-Based Attitude Determination in the Measurement Domain
Sensors, 2017 A multi-antenna-based GNSS receiver is capable of providing high-precision and drift-free attitude solution. Carrier phase measurements need be utilized to achieve high-precision attitude. The traditional attitude determination methods in the measurement

Long Baseline GPS+BDS RTK Positioning with Partial Ambiguity Resolution [PDF]
The International Technical Meeting of the The Institute of Navigation, 2017 Reliable real-time kinematic positioning requires the occurrence of incorrect integer ambiguity estimates to be limited to a maximum tolerable rate. For long baselines this usually implies long convergence times due to the presence of atmospheric delay parameters.

Molecular Oncology, EarlyView.EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Interpreting the effects of DNA polymerase variants at the structural level
Molecular Oncology, EarlyView.Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...
