The role of initial state and final quench temperature on the aging properties in phase-ordering kinetics
We study numerically the two-dimensional Ising model with non-conserved
dynamics quenched from an initial equilibrium state at the temperature to a final temperature below the critical one. By considering
processes initiating both from a disordered state at infinite temperature
and from the critical configurations at and spanning the
range of final temperatures we elucidate the role played by
and on the aging properties and, in particular, on the behavior of
the autocorrelation and of the integrated response function . Our
results show that for any choice of , while the autocorrelation function
exponent takes a markedly different value for
[] or [] the response function exponents are unchanged. Supported by the outcome
of the analytical solution of the solvable spherical model we interpret this
fact as due to the different contributions provided to autocorrelation and
response by the large-scale properties of the system. As changing is
considered, although this is expected to play no role in the
large-scale/long-time properties of the system, we show important effects on
the quantitative behavior of . In particular, data for quenches to
are consistent with a value of the response function exponent different from the one [] found in a wealth of previous numerical determinations
in quenches to finite final temperatures. This is interpreted as due to
important pre-asymptotic corrections associated to .Comment: 25 pages, 15 figures. To appear on Phys. Rev.
Role of initial state and final quench temperature on aging properties in phase-ordering kinetics
PARSEME corpora annotated for verbal multiword expressions (version 1.3)
This multilingual resource contains corpora in which verbal MWEs have been manually annotated. VMWEs include idioms (let the cat out of the bag), light-verb constructions (make a decision), verb-particle constructions (give up), inherently reflexive verbs (help oneself), and multi-verb constructions (make do). This is the first release of the corpora without an associated shared task. Previous version (1.2) was associated with the PARSEME Shared Task on semi-supervised Identification of Verbal MWEs (2020). The data covers 26 languages corresponding to the combination of the corpora for all previous three editions (1.0, 1.1 and 1.2) of the corpora. VMWEs were annotated according to the universal guidelines. The corpora are provided in the cupt format, inspired by the CONLL-U format. Morphological and syntactic information, including parts of speech, lemmas, morphological features and/or syntactic dependencies, are also provided. Depending on the language, the information comes from treebanks (e.g., Universal Dependencies) or from automatic parsers trained on treebanks (e.g., UDPipe). All corpora are split into training, development and test data, following the splitting strategy adopted for the PARSEME Shared Task 1.2. The annotation guidelines are available online: https://parsemefr.lis-lab.fr/parseme-st-guidelines/1.3 The .cupt format is detailed here: https://multiword.sourceforge.net/cupt-format
