How Do Transformers Learn Variable Binding in Symbolic Programs?
Variable binding -- the ability to associate variables with values -- is fundamental to symbolic computation and cognition. Although classical architectures typically implement variable binding via addressable memory, it is not well understood how modern neural networks lacking built-in binding operations may acquire this capacity. We investigate this by training a Transformer to dereference queried variables in symbolic programs where variables are assigned either numerical constants or other …

Substructural Abstract Syntax with Variable Binding and Single-Variable Substitution
We develop a unified categorical theory of substructural abstract syntax with variable binding and single-variable (capture-avoiding) substitution. This is done for the gamut of context structural rules given by exchange (linear theory) with weakening (affine theory) or with contraction (relevant theory) and with both (cartesian theory). Specifically, in all four scenarios, we uniformly: define abstract syntax with variable binding as free algebras for binding-signature endofunctors over variab…

Evidence for supramolecular dynamics of non-hydrogen bonding polar van der Waals liquids
Non-hydrogen bonding van der Waals liquids with dipole-dipole interactions are typically viewed as non-associative and not considered able to sustain large supramolecular structures. Combining broadband dielectric spectroscopy (BDS) and rheology, we demonstrate the supramolecular formation in a group of non-hydrogen-bonding van der Waals liquids, i.e. 1-bromo-2-ethylhexane, 1-chloro-2-ethylhexane, and 1-bromo-3,7-dimethyloctane. BDS shows an emergence of a Debye-like process slower than their s…

Vraag Bontenbal: Gaat het NSC nooit meer met de PVV in een kabinet?
Van Vroonhoven: "Wilders heeft het werken eigenlijk onmogelijk gemaakt".
Dat is weer zo'n typisch Omtzigtiaans aantwoord. Vooral het woordje 'eigenlijk".
Destijds zei Pieter "Je kunt toch echt alleen een coalitie vormen met partijen die zich houden aan de klassieke grondrechten".
Waarna alle media concludeerden: de PVV wordt uitgesloten.
Nou, we weten hoe letterlij…

Sequential binding-unbinding based specific interactions highlight exchange dynamics and size distribution of condensates
Understanding the mechanisms of formation of organelles and biomolecular condensates via liquid-liquid phase separation is a topic of great interest. It is reasonable to assume that the formation of protein-specific condensates inside a crowded, multicomponent cellular environment requires specific protein-protein interactions with lifetimes longer than non-specific protein-protein interactions. These longer-lived, specific interactions can arise through complex protein binding and unbinding pa…

Ukraine-Liveblog: ++ AKW Saporischschja wieder extern versorgt ++
Die externe Stromversorgung des von Russland besetzten Atomkraftwerks Saporischschja funktioniert laut der Internationalen Atomenergiebehörde wieder. US-Präsident Trump will offenbar mit der Ukraine bei der Luftverteidigung zusammenarbeiten.
