View Order With Arbitrary Center Echoes

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 5, Page 2127-2139, November 2026.
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...

Nonmonotonic and Paraconsistent Reasoning: From Basic Entailments to Plausible Relations

open access: yes, 1999
. In this paper we develop frameworks for logical systems which are able to reflect not only nonmonotonic patterns of reasoning, but also paraconsistent reasoning.

The Political U: New Evidence on the Economic Costs of Hybrid Regimes

open access: yesEconomics &Politics, Volume 38, Issue 3, Page 747-769, November 2026.
ABSTRACT Recent research establishes a positive causal effect from democracy to income, although this evidence relies mostly on binary regime classifications. We extend the identification framework of Acemoglu et al. (2019) to a classification that distinguishes democracies, autocracies, and hybrid regimes for about 170 countries over 1960–2024.

Nonmonotonic reasoning - From cataloguing to analogizing

open access: yes, 2010
PRich008International audienceReasoning deductively under incomplete information is nonmonotonic in nature since the arrival of supplementary information may invalidate or reverse previously obtained conclusions. It amounts to apply generic default rules

Surrogate Computational Homogenization Enhanced by Partition‐of‐Unity RBF Interpolation With Decision Trees

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 20, 30 October 2026.
ABSTRACT This study enhances a framework of surrogate computational homogenization (SCH) using decision tree‐based partition‐of‐unity radial basis function (PU‐RBF) interpolation for three‐dimensional finite‐deformation two‐scale analysis. The method addresses the scalability limitation of global RBF interpolation for large numerical material test (NMT)

Towards First-Order Nonmonotonic Reasoning

open access: yes, 2007
. We investigate the problem of reasoning in nonmonotonic extensions of first-order logic. In particular, we study reasoning in firstorder MKNF, the modal logic of minimal knowledge and negation as failure introduced by Lifschitz.

Phase‐Controlled Asymmetric Resonances for Enhanced Spectral Slope in a Ge‐OI Microring Resonator at 4.2 μm

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A localized air‐hole perturbation in a mid‐infrared Ge‐on‐insulator microring enables phase‐controlled evolution from Lorentzian‐like to Fano‐like resonances. The strongest spectral discrimination emerges at an intermediate perturbation, where a loaded Q of 2.15 × 105 and a slope rate of 435 dB/nm are achieved, revealing a practical route to high‐Q ...

Situated nonmonotonic temporal reasoning with BABY-SIT [PDF]

open access: yes, 1997
After a review of situation theory and previous attempts at 'computational' situation theory, we present a new programming environment, BABY-SIT, which is based on situation theory. We then demonstrate how problems requiring formal temporal reasoning can

Nonmonotonic belief state frames and reasoning frames

open access: yes, 1995
In this paper five levels of specification of nonmonotonic reasoning are distinguished. The notions of semantical frame, belief state frame and reasoning frame are introduced and used as a semantical basis for the first three levels.
