Gender Distribution and Geography of Highly Cited Papers in ACS Catalysis
No full textFollowing the editorial series presented in ACS Catalysis in 2020, I investigated the gender distribution in highly cited ACS Catalysis papers. As a main result, I found that from the 155 highly cited papers that showed up in my analysis, only 15 papers have female corresponding author(s) (9.7%), and only 5 of these 15 papers have solely female corresponding author(s) (3.2%). I also analyzed geographical distribution and found that two new categories "Small Countries", including for example Cyprus, Greece, Iceland, and Ireland, and "Developing Countries", including Mexico, South Africa, Thailand, and Vietnam, provide significant contributions to ACS Catalysis, larger than Canada or UK, based on the defined metrics

Models relevant to excess heat production in fleischmann-pons experiments
No full textIn Low-Energy Nuclear Reactions Sourcebook; Marwan, J., et al.;
ACS Symposium Series; American Chemical Society: Washington, DC, 2008.Observations of excess heat in the absence of commensurate energetic charged particles challenges local energy and momentum conservation, a foundation of nuclear physics. We have explored models based on excitation transfer, in which global energy is conserved but local energy conservation is violated. We present recent results on both excitation transfer and anomalous energy exchange within the context of lossless spin-boson models. We introduce a rotation that allows us to isolate terms in the rotated Hamiltonian responsible for both processes. Spin-boson type models augmented with loss appear to be sufficiently strong to account for the excess heat effect
Towards a sustainable partnership between ACS & FACS: What's next?
No full text© 2015 American Chemical Society.Today, the Chinese economy (GDP US3.6 t), France (2.7 t) & UK (2.4 t) put together. The combined economies of China, Japan (2.0) are matching that of the USA ($16.2). By 2018, the Chinese economy alone is expected to reach 70% of the U.S. economy. The accelerating growth of Asian economies has brought along immense opportunities not only in business but also in research collaboration, adoption of new technologies, and education exchanges. The emergence of Asia has presented exciting prospects in the chemical sciences â€" from education to technology, from environment to energy, from health to business. How do we grow the partnership between ACS and FACS (Federation of Asian Chemical Societies) amidst these vigorous developments and changes? What are the biggest opportunities that Asia has presented and the challenges that the strategic partnership will face? In this article, the author touches on these topics and gives his views on the way forward.link_to_subscribed_fulltex
A new modification of the chiron ACS assay for total prostate-specific antigen achieves equimolar response characteristics and improves the detection of prostate cancer
No full textNonequimolar-response assays for prostate-specific antigen (PSA) are criticized for overestimating total PSA in some men without prostate cancer (PCA), and underestimating total PSA in some men with PCA. We recently studied three nonequimolar-response PSA assays that had undergone modifications. While two of the studied assays achieved equimolar-response characteristics with improved areas under receiver operating characteristic (ROC) curves (AUC), the modification of the Chiron ACS PSA assay (ACS PSA2, Chiron) failed to achieve this. Recently, the ACS assay underwent another modification (ACS PSA, Bayer), which we investigated. Sera from 305 men (155 without and 150 with PCA, PSA greater than or equal to2 and less than or equal to30 mug/l, TandemE) were measured using both modifications of the ACS assay and equimolar-response reference methods (TandemR free and Tandem E, Hybritech). Molar response relative to the reference method and clinical performance (comparison of AUCs) between the previous and new ACS assay modifications were studied. The new modification of the ACS assay (ACS PSA, Bayer) achieved equimolar-response characteristics but reported lower values (average 10%) than the Tandem E assay. Compared to the previous modification (ACS PSA2, Chiron), a 3% improvement in AUC (p=0.01) was found. Using results of the redesigned equimolar-response assay (ACS PSA, Bayer), we calculated that 6 of 155 men without PCA in this sample set could be spared unnecessary biopsy compared with the previous nonequimolar-response assay (ACS PSA2, Chiron) without missing additional PCA (90% sensitivity). These data provide additional evidence for clinical advantages of equimolar-response over nonequimolar-response PSA assay formats
The ACS Nearby Galaxy Survey Treasury. III. Cepheids In The Outer Disk Of M81
No full textThe ACS Nearby Galaxy Survey Treasury (ANGST) has acquired deep ACS imaging of a field in the outer disk of the large spiral galaxy M81. These data were obtained over a total of 20 Hubble Space Telescope orbits, providing a baseline long enough to reliably identify Cepheid variable stars in the field. Fundamental mode and first overtone types have been distinguished through comparative fits with corresponding Cepheid light curve templates derived from principal component analysis of confirmed Cepheids in the Large Magellanic Cloud (LMC), Small Magellanic Cloud, and Milky Way. A distance modulus of 27.78 +/- 0.05(r) +/- 0.14(s) with a corresponding distance of 3.60 +/- 0.23 Mpc has been calculated from a sample of 11 fundamental mode and two first overtone Cepheids (assuming an LMC distance modulus of mu(LMC) = 18.41 +/- 0.10(r) +/- 0.13(s)).NASA G0-10915, NAS5-26555Space Telescope Institute AR-10945Astronom
Data from: A Guide to the American Community Survey (ACS) for the Rural Researcher: Unpacking the Conceptual and Technical Aspects of Using Secondary Data for Rural Research
No full textPlease cite as: Kristie LeBeau. (2023) Data from: A Guide to the American Community Survey (ACS) for the Rural Researcher: Unpacking the Conceptual and Technical Aspects of Using Secondary Data for Rural Research. [dataset] Cornell University eCommons Repository. https://doi.org/10.7298/rvr0-xn48These files contain data supporting all results reported in LeBeau's A Guide to the American Community Survey (ACS) for the Rural Researcher: Unpacking the Conceptual and Technical Aspects of Using Secondary Data for Rural Research. This article aims to advance research methods for rural researchers by offering guidelines for navigating high levels of error associated with the American Community Survey (ACS). The ACS presents a useful source of US community level data for rural researchers to utilize in school-community research but not without its difficulties. The small population sizes of rural communities often translate to large margins of error in the data, presenting a degree of uncertainty in the actual measure. To illustrate challenges and best practice, the author conducts a case study of the relationship between the presence of schools and economic vitality of rural communities in Indiana using ACS data. The author demonstrates how to examine the error in the data, introduces options to reduce uncertainty, and ultimately, explains how to move forward with the data, working with the margin of error and acknowledging its presence in the analysis and results. This article offers suggestions and techniques to assist rural researchers in navigating ACS obstacles so that they might produce transparent results with as little uncertainty as possible
Hydrodynamics of Diamond-Shaped Gradient Nanopillar Arrays for Effective DNA Trans location into Nano channels
No full textabstract: Effective DNA translocation into nanochannels is critical for advancing genome mapping and future single-molecule DNA sequencing technologies. We present the design and hydrodynamic study of a diamond-shaped gradient pillar array connected to nanochannels for enhancing the success of DNA translocation events. Single-molecule fluorescence imaging is utilized to interrogate the hydrodynamic interactions of the DNA with this unique structure, evaluate key DNA translocation parameters, including speed, extension, and translocation time, and provide a detailed mapping of the translocation events in nanopillar arrays coupled with 10 and 50 μm long channels. Our analysis reveals the important roles of diamond-shaped nanopillars in guiding DNA into as small as 30 nm channels with minimized clogging, stretching DNA to nearly 100% of their dyed contour length, inducing location-specific straddling of DNA at nanopillar interfaces, and modulating DNA speeds by pillar geometries. Importantly, all critical features down to 30 nm wide nanochannels are defined using standard photolithography and fabrication processes, a feat aligned with the requirement of high-volume, low-cost production.This document is the Accepted Manuscript version of a Published Work that appeared in final form in
