Induction in Saturation

open access: yes
Abstract Proof by induction is commonplace in modern mathematics and computational logic. This paper overviews and discusses our recent results in turning saturation-based first-order theorem proving into a powerful framework for automating inductive reasoning.

On the Saturation of YAGO

open access: yes, 2010
YAGO is an automatically generated ontology out of Wikipedia and WordNet. It is eventually represented in a proprietary flat text file format and a core comprises 10 million facts and formulas. We present a translation of YAGO into the Bernays-Schonfinkel Horn class with equality.

Saturation of Ordered Graphs

open access: yesSIAM Journal on Discrete Mathematics, 2023
Recently, the saturation problem of $0$-$1$ matrices gained a lot of attention. This problem can be regarded as a saturation problem of ordered bipartite graphs. Motivated by this, we initiate the study of the saturation problem of ordered and cyclically ordered graphs.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Automorphisms of Saturated and Boundedly Saturated Models of Arithmetic

open access: yesNotre Dame Journal of Formal Logic, 2011
We discuss automorphisms of saturated models of PA and boundedly saturated models of PA. We show that Smorynski's Lemma and Kaye's Theorem are not only true for countable recursively saturated models of PA but also true for all boundedly saturated models of PA with slight modifications.

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Deuterium retention in recrystallized tungsten exposed to high-flux plasma with fluences up to 1 × 1029 m−2

open access: yesNuclear Fusion
Plasma fluence at the divertor of a future magnetic confinement fusion device can accumulate up to ∼10 ^28 –10 ^29 m ^−2 per year. Yet hydrogen isotope (HI) retention under such high-fluence plasma exposure has been rarely reported.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
