Standard super-activation for Gaussian channels requires squeezing

The quantum capacity of bosonic Gaussian quantum channels can be non-additive in a particularly striking way: a pair of such optical-fiber type channels can individually have zero quantum capacity but super-activate each other such that the combined channel has strictly positive capacity. This has been shown in [Nature Photonics 5, 624 (2011)] where it was conjectured that squeezing is a necessary resource for this phenomenon. We provide a proof of this conjecture by showing that for gauge covariant channels a Choi matrix with positive partial transpose implies that the channel is entanglement-breaking. In addition, we construct an example which shows that this implication fails to hold for Gaussian channels which arise from passive interactions with a squeezed environment.Comment: 5 pages, close to published versio

Citations versus expert opinions: Citation analysis of Featured Reviews of the American Mathematical Society

Peer review and citation metrics are two means of gauging the value of scientific research, but the lack of publicly available peer review data makes the comparison of these methods difficult. Mathematics can serve as a useful laboratory for considering these questions because as an exact science, there is a narrow range of reasons for citations. In mathematics, virtually all published articles are post-publication reviewed by mathematicians in Mathematical Reviews (MathSciNet) and so the data set was essentially the Web of Science mathematics publications from 1993 to 2004. For a decade, especially important articles were singled out in Mathematical Reviews for featured reviews. In this study, we analyze the bibliometrics of elite articles selected by peer review and by citation count. We conclude that the two notions of significance described by being a featured review article and being highly cited are distinct. This indicates that peer review and citation counts give largely independent determinations of highly distinguished articles. We also consider whether hiring patterns of subfields and mathematicians' interest in subfields reflect subfields of featured review or highly cited articles. We reexamine data from two earlier studies in light of our methods for implications on the peer review/citation count relationship to a diversity of disciplines.Comment: 21 pages, 3 figures, 4 table

Machine learning applied to enzyme turnover numbers reveals protein structural correlates and improves metabolic models.

Knowing the catalytic turnover numbers of enzymes is essential for understanding the growth rate, proteome composition, and physiology of organisms, but experimental data on enzyme turnover numbers is sparse and noisy. Here, we demonstrate that machine learning can successfully predict catalytic turnover numbers in Escherichia coli based on integrated data on enzyme biochemistry, protein structure, and network context. We identify a diverse set of features that are consistently predictive for both in vivo and in vitro enzyme turnover rates, revealing novel protein structural correlates of catalytic turnover. We use our predictions to parameterize two mechanistic genome-scale modelling frameworks for proteome-limited metabolism, leading to significantly higher accuracy in the prediction of quantitative proteome data than previous approaches. The presented machine learning models thus provide a valuable tool for understanding metabolism and the proteome at the genome scale, and elucidate structural, biochemical, and network properties that underlie enzyme kinetics

INCREASING HEALTH LITERACY AND ACADEMIC PERFORMANCE AMONG HISPANIC AND LATINO STUDENTS IN DURHAM COUNTY PUBLIC SCHOOLS THROUGH SCHOOL MEALS

Education access and quality is a key social determinant of health that has a major influence on wellbeing (Healthy People 2030, n.d.). Higher levels of education have been shown to lead to increased opportunities, employment, income, and health status (The Lancet Public Health, 2020). Health literacy plays a large role in the decreased health status among those with lower educational attainment. Inadequate health literacy has been shown to have a stronger association with poor health than age, income, employment status, or race (Shahid et al., 2022). Within Durham County, race is highly associated with educational attainment, as over 50% of both Hispanic males and females do not have a high school diploma compared to less than 5% of white males and females (Statistical Atlas, 2018). This proposal will create both a cultural school meal food program as well as a health literacy and English-as-a-second-language (ESL) curriculum within Durham Public Schools (DPS). These proposed programs will create improvements in academic performance and health literacy among Hispanic/Latino youth, leading to long term improvements in the overall health status of Durham County’s greater Hispanic/Latino community.Master of Public Healt
