Double difference integer ambiguity resolution in GPS phase measurements collected on points of permanent stations network

, 2007
Estymację lokalnych różnicowych modeli refrakcji poprzedza się wstępnym opracowaniem pomiarów fazowych zarejestrowanych w sieci stacji permanentnych GPS, w celu wyznaczenia całkowitoliczbowych początkowych nieoznaczoności cykli fazowych.

Preschool Duration, Family Background and Long‐Term Outcomes: Evidence From the Expansion of École Maternelle in France

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper analyses the long‐term effects of preschool education in France. We focus on the effect of preschool duration on educational attainment and labour market earnings in adulthood. Building on an old tradition of free and universal pre‐primary education, France implemented in the late 1960s a large‐scale expansion of preschooling ...

Panel Sequential Group Estimation of Interactive Effects Models

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper proposes a novel procedure to identify latent groups in the slopes of panel data models with interactive effects. The method is straightforward to apply and relies only on closed‐form estimators when evaluating the objective function.

The Drivers of Science Referenced in US EPA Regulatory Impact Analyses: Open Access, Professional Popularity, and Agency Involvement

Regulation &Governance, EarlyView.
ABSTRACT We perform bibliometric analysis on documents for 255 Regulatory Impact Analyzes (RIAs) prepared by the US Environmental Protection Agency (EPA) from 1980 through 2024. Using a series of automated information extraction methods, we extract references from these documents and match them to bibliographic records.

The I in logic

Theoria, EarlyView.
Abstract This paper argues for the significance of Kaplan's logic LD in two ways: first, by looking at how logic got along before we had LD, and second, by using it to bring out the similarity between David Hume's thesis that one cannot deduce claims about the future on the basis of premises only about the past, and the so‐called "essentiality" of the ...

Utility of local capillary supply indices: Insights from computational image‐based modelling

The Journal of Physiology, EarlyView.
Abstract figure legend Local capillary distribution and fibre geometry influence oxygen availability in skeletal muscle. Image‐based modelling of tissue PO2${{P}_{{{{\mathrm{O}}}_2}}}$ shows that area‐based measures of capillary supply – the local capillary density (LCDi) and local maximum diffusion distance (Dmax,i) – most accurately represent the ...
