Dendriform-Tree Setting for Fully Non-commutative Fliess Operators

This paper provides a dendriform-tree setting for Fliess operators with matrix-valued inputs. This class of analytic nonlinear input-output systems is convenient, for example, in quantum control. In particular, a description of such Fliess operators is provided using planar binary trees. Sufficient conditions for convergence of the defining series are also given

Lessons Learned from Citizen Science in the Classroom. A Response to The Future of Citizen Science.

Mueller, Tippins, and Bryan’s contrast of the current limitations of science education with the potential virtues of citizen science provides an important theoretical perspective about the future of democratized science and K–12 education. However, the authors fail to adequately address the existing barriers and constraints to moving community-based science into the classroom. We contend that for these science partnerships to be successful, teachers, researchers, and other program designers must reexamine questions about traditional science education and citizen-science programs and attend to certain dimensions, including: framing these projects around the nature of science, creating a dialog with experts and allowing access to the primary literature, and fostering the ability of the public to critique information and evidence. We argue that the resource constraints of scientists, teachers, and students likely pose problems to moving true democratized science into the classroom

Routine Screening of Adolescents for Trichomonas vaginalis in a Juvenile Detention Center

Background: Detained and incarcerated adolescents are at increased risk of sexually transmitted infections (STI), but limited information is currently available regarding the prevalence of Trichomonas vaginalis (TV) in detained youth.Methods: A total of 144 detainees (75 males and 69 females) in the Franklin County Juvenile Detention Facility (FCJDF) in Columbus, Ohio, consented to STI screening between May 2016 and June 2017. Participants were screened for TV in addition to Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) using urine nucleic acid amplification tests (NAAT).Results: Among detained youth who consented to testing, TV was identified in 7 of 69 (10.1%) females and 0 of 75 (0%) males (P <0.01). Neisseria gonorrhoeae was identified in 12 of 69 (17.4%) females and 3 of 75 (4.0%) males (P = 0.01), and CT was identified in 16 of 69 (23.2%) female and 7 of 75 (9.3%) male detainees (P = 0.04). Among females, positive TV screen was associated with prior history of STI.Conclusion: Our data support routine screening of female detainees at FCJDF, based on our finding of 10% posi-tivity among females who underwent testing
