Remote Sensing, 2021 The single-receiver integer ambiguity resolution-enabled variant of precise point positioning (PPP), namely PPP-RTK, has proven to be crucial in reducing the long convergence time of PPP solutions through the recovery of the integerness of the user ...

British Journal of Clinical Pharmacology, EarlyView.Aims Oral administration of (S)‐ketamine for treatment‐resistant depression (TRD), as alternative to the registered intranasal or off‐label intravenous administrations, has high potential. However, it is characterized by an extensive first‐pass metabolism, resulting in low (S)‐ketamine exposure and high levels of active metabolites, including (S ...

Perturbative and non-perturbative aspects of moments of the thrust distribution in e+e- annihilation
, 2000 Resummation and power-corrections play a crucial role in the phenomenology of event-shape variables like the thrust T. Previous investigations showed that the perturbative contribution to the average thrust is dominated by gluons of small invariant mass,

Roles of 2D halide perovskites in 2D/3D heterojunctions for high‐performance perovskite solar cells
Bulletin of the Korean Chemical Society, EarlyView.This review establishes a design framework for two‐dimensional (2D)/three‐dimensional (3D) perovskite heterojunctions, redefining the 2D perovskite layer as an active semiconductor component. We classify 2D structures by spacer chemistry and analyze their roles within the heterojunction.

OFDM-Based Carrier Phase Localization With Integer Ambiguity Resolution
IEEE AccessThis study introduces a two-stage Time Difference of Arrival (TDoA) localization method using OFDM signals with carrier-phase measurements. Unlike conventional methods, our approach uniquely resolves integer ambiguities in carrier-phase signals by ...

Integer Ambiguity Fixation Based on SC-PAR Algorithm
Journal of Physics: Conference Series, 2021 Abstract In terms of quality control of ambiguity estimation, the common partial ambiguity fixation algorithm is improved, and the SC-PAR (Single frequency Combined Partial Ambiguity Resolution) algorithm is proposed. After the algorithm fails to fix the full ambiguity, it filters the ambiguity subset step by step according to the number

Board Networks and Corporate Carbon Emissions: A Cross‐Country Analysis of Causal Effects
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines whether board networks influence corporate carbon emissions and the strategic pathways through which firms decarbonize. Using a sample of 1952 firms across 48 countries from 2003 to 2020, we employ dynamic stacked regressions that exploit exogenous carbon‐regulation shocks affecting firms connected through shared third ...

A goodness‐of‐fit test for regression models with discrete outcomes
Canadian Journal of Statistics, EarlyView.Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.
