Argument structure and the eventive-stative alternation in extent verbs
GlossaThis study focuses on a group of so-called extent verbs (Gawron 2009) in Spanish (cf. rodear ‘surround’, cubrir ‘cover’, or bordear ‘border’) that show an alternation between an eventive and a stative reading,

Parallel Product of Event Structures
DAIMI Report Series, 1989 The parallel product operator may be defined very easily on flow event structures. We show that, for flow event structures satisfying a particular constraint, which is preserved by ususal process operators, this product may be characterised as a categorical product.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

1-Safe Petri nets and special cube complexes: equivalence and applications
, 2019 Nielsen, Plotkin, and Winskel (1981) proved that every 1-safe Petri net $N$ unfolds into an event structure $\mathcal{E}_N$. By a result of Thiagarajan (1996 and 2002), these unfoldings are exactly the trace regular event structures.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Event Structure without naïve Physics
, 2019 What is the real nature of the aspectual division between perfective and imperfective as revealed by the well-known in/for-test? The answer is founded on the idea that this division between completion and incompletion mirrors our cognitive capacity to shift between discreteness and continuity as expressed in the number systems N and R.

Probabilistic Event Structures and Domains
BRICS Report Series, 2004 This paper studies how to adjoin probability to event structures, leading to the model of probabilistic event structures. In their simplest form probabilistic choice is localised to cells, where conflict arises; in which case probabilistic independence coincides with causal independence.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
