Interactions and integrability in weakly monitored Hamiltonian systems
Full text linkInterspersing unitary dynamics with local measurements results in
measurement-induced phases and transitions in many-body quantum systems. When
the evolution is driven by a local Hamiltonian, two types of transitions have
been observed, characterized by an abrupt change in the system size scaling of
entanglement entropy. The critical point separates the strongly monitored
area-law phase from a volume law or a sub-extensive, typically logarithmic-like
one at low measurement rates. Identifying the key ingredients responsible for
the entanglement scaling in the weakly monitored phase is the key purpose of
this work. For this purpose, we consider prototypical one-dimensional spin
chains with local monitoring featuring the presence/absence of U(1) symmetry,
integrability, and interactions. Using exact numerical methods, the system
sizes studied reveal that the presence of interaction is always correlated to a
volume-law weakly monitored phase. In contrast, non-interacting systems present
sub-extensive scaling of entanglement. Other characteristics, namely
integrability or U(1) symmetry, do not play a role in the character of the
entanglement phase.Comment: 4 pages, 4 figure
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Complexity of spin configurations dynamics due to unitary evolution and periodic projective measurements
Full text linkWe study the Hamiltonian dynamics of a many-body quantum system subjected to
periodic projective measurements which leads to probabilistic cellular automata
dynamics. Given a sequence of measured values, we characterize their dynamics
by performing a principal component analysis. The number of principal
components required for an almost complete description of the system, which is
a measure of complexity we refer to as PCA complexity, is studied as a function
of the Hamiltonian parameters and measurement intervals. We consider different
Hamiltonians that describe interacting, non-interacting, integrable, and
non-integrable systems, including random local Hamiltonians and translational
invariant random local Hamiltonians. In all these scenarios, we find that the
PCA complexity grows rapidly in time before approaching a plateau. The dynamics
of the PCA complexity can vary quantitatively and qualitatively as a function
of the Hamiltonian parameters and measurement protocol. Importantly, the
dynamics of PCA complexity present behavior that is considerably less sensitive
to the specific system parameters for models which lack simple local dynamics,
as is often the case in non-integrable models. In particular, we point out a
figure of merit that considers the local dynamics and the measurement direction
to predict the sensitivity of the PCA complexity dynamics to the system
parameters.Comment: 9 pages, 8 figure
