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 ...

Orbit and clock products for quad-system satellites with undifferenced ambiguity fixing approach

Satellite Navigation
Integer Ambiguity Resolution (IAR) can significantly improve the accuracy of GNSS Precise Orbit Determination (POD). Traditionally, the IAR in POD is achieved at the Double Differenced (DD) level.

An Introduction to Rational Constructivism in Cognitive Development

Topics in Cognitive Science, EarlyView.
Abstract Rational constructivism is a contemporary theory of cognitive development. It proposes that children generate, tweak, and radically revise theories, beliefs, and representations by integrating evidence with existing knowledge via probabilistic inferential learning mechanisms.

Phase Ambiguity Resolution For Stacked Radar [PDF]

, 2007
Phase ambiguity resolution is one of the main problems in geodetic techniques involving electromagnetic phase measurements. For repeat-pass radar interferometry, the phase difference between two resolution cells in an interferogram usually reflects a ...

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 ...

Blind Estimation Versus Direct Measurement of the Arterial Input Function in Dynamic Contrast‐Enhanced MRI of the Breast

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1947-1955, October 2026.
PurposeAccurate arterial input functions (AIFs) are essential for quantitative dynamic contrast‐enhanced (DCE) MRI, yet direct measurement is challenging and population‐averaged AIFs neglect patient‐specific variability. Blind deconvolution provides an alternative by estimating patient‐specific AIFs directly from tissue data, up to a scale factor. This

Acceleration of PPP Integer Ambiguity Resolution When Emploing Ionospheric Delays [PDF]

Precise Point Positioning (PPP) is a powerful method for GNSS data processing, when observations from only one receiver are utilized. Since any systematic error is not eliminated by between-stations differencing, introduced precise products and models ...

Effect of phase centre variation on tropospheric delay in PPP‐AR with low‐cost global navigation satellite systems receiver and antenna

IET Radar, Sonar & Navigation
As low‐cost global navigation satellite systems receiver and antenna become increasingly prevalent for water vapour monitoring, precise millimetre‐level characterisation of instrument biases is crucial for maintaining measurement accuracy and reliability.

Bayesian Implementation of the Factor‐Analytic Mixed Model and Application to Embeddings

Stat, Volume 15, Issue 3, September 2026.
ABSTRACT Mixed models and neural networks each offer complementary frameworks for prediction. Theoretically grounded in inference, mixed models can unveil latent variance structure notably with the factor‐analytic approach. In this article, we propose to bridge the gap between the two frameworks, leveraging embedding data from a neural network encoder ...
