Graph Algebras for Bigraphs [PDF]

open access: yes, 2010
Binding bigraphs are a graphical formalism intended to be a meta-model for mobile, concurrent and communicating systems. In this paper we present an algebra of typed graph terms which correspond precisely to binding bigraphs over a given signature.

Emotion-Cause Pair Extraction: A New Task to Emotion Analysis in Texts [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2019
Emotion cause extraction (ECE), the task aimed at extracting the potential causes behind certain emotions in text, has gained much attention in recent years due to its wide applications.

Pulsational Pair-instability Supernovae [PDF]

open access: yes, 2016
The final evolution of stars in the mass range 70–140 M ⊙ is explored. Depending upon their mass loss history and rotation rates, these stars will end their lives as pulsational pair-instability supernovae (PPISN) producing a great variety of ...

Language contact in South Oscan epigraphy [PDF]

open access: yes, 2014
This thesis examines evidence for language contact between Oscan and Greek in the corpus of Oscan inscriptions from Lucania, Bruttium and Messana. These inscriptions were written in an adapted form of the Greek alphabet from around the fourth to first ...

Total top-quark pair-production cross section at hadron colliders through O(αS(4)). [PDF]

open access: yesPhysical Review Letters, 2013
We compute the next-to-next-to-leading order (NNLO) quantum chromodynamics (QCD) correction to the total cross section for the reaction gg → tt + X. Together with the partonic channels we computed previously, the result derived in this Letter completes ...

Charge-insensitive qubit design derived from the Cooper pair box [PDF]

open access: yes, 2007
Short dephasing times pose one of the main challenges in realizing a quantum computer. Different approaches have been devised to cure this problem for superconducting qubits, a prime example being the operation of such devices at optimal working points ...

Trees and graph packing [PDF]

open access: yes, 2018
In this thesis we investigate two main topics, namely, suffix trees and graph packing problems. In Chapter 2, we present the suffix trees. The main result of this chapter is a lower bound on the size of simple suffix trees.

Minimum $k$-critical-bipartite graphs: the irregular Case

open access: yes, 2023
We study the problem of finding a minimum $k$-critical-bipartite graph of order $(n,m)$: a bipartite graph $G=(U,V;E)$, with $|U|=n$, $|V|=m$, and $n>m>1$, which is $k$-critical-bipartite, and the tuple $(|E|, \Delta_U, \Delta_V)$, where $\Delta_U$ and $\
