Branching cells for asymmetric event structures [PDF]

, 2014
27 pages. Part of a submission with co-authors.We introduce branching cells for Asymmetric Event Structures. They provide a way to decompose maximal configuration in a dynamic way through elementary steps representing elementary choices made during a ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Concurrency Models with Causality and Events as Psi-calculi [PDF]

Electronic Proceedings in Theoretical Computer Science, 2014
Psi-calculi are a parametric framework for nominal calculi, where standard calculi are found as instances, like the pi-calculus, or the cryptographic spi-calculus and applied-pi.

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 ...

A Cartesian closed category of event structures with quotients

Discrete Mathematics & Theoretical Computer Science, 2006
We introduce a new class of morphisms for event structures. The category obtained is Cartesian closed, and a natural notion of quotient event structure is defined within it.

Structural Influence on Radiation-induced Single-event Effects in SiC MOSFETs: Comparative Analysis of Planar and Trench Designs

Yuanzineng kexue jishu
The single-event susceptibility of three silicon carbide (SiC) metal-oxide-semiconductor field-effect transistor (MOSFET) power devices structures (planar, trench and double trench) is researched by the technology computer-aided design (TCAD) simulation.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

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.

Two-dimensional discrete wavelet analysis of multiparticle event topology in heavy ion collisions

, 2007
The event-by-event analysis of multiparticle production in high energy hadron and nuclei collisions can be performed using the discrete wavelet transformation. The ring-like and jet-like structures in two-dimensional angular histograms are well extracted

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 ...

Multiple-Event Catastrophe Bond Pricing Based on CIR-Copula-POT Model

Discrete Dynamics in Nature and Society, 2018
Catastrophe events are attracting increased attention because of their devastating consequences. Aimed at the nonlinear dependency and tail characteristics of different triggered indexes of multiple-event catastrophe bonds, this paper applies Copula ...
