Integrating the ReCiter author disambiguation engine with a faculty information system

<div>Libraries and other administrative departments at medical universities are regularly called upon to produce reports detailing scholarly publications authored by members of their scholarly community. </div><div><br></div><div>ORCID is touted as a solution to the problem of author disambiguation, and Weill Cornell Medical Library has explored this option. Despite growing interest, our analyses have shown ORCID's publication lists for an average person remain unreliable. Publisher mandates appear to have improved accuracy, but it's rare for all authors of a publication to be indexed with an ORCID ID. Practically speaking, we don't have the staff to manually assert publications on behalf of thousands of people, or the authority to require such people to maintain their own profiles. Indeed, we have even less influence over non-employees such as residents and voluntary faculty as well as inactive people such as alumni and historical faculty, all of whom we're called to report upon.</div><div><br></div><div>For this reason, Weill Cornell Medicine has continued to pursue development of ReCiter, a homegrown Java-based tool which uses institutionally-maintained identity data to perform author name disambiguation using records harvested from PubMed. ReCiter employs 15 separate strategies for disambiguation including department name, known co-investigators, and year of degree.</div><div><br></div><div>Fundamentally speaking, ReCiter is a publication suggestion engine. Provide it with a full complement of identity data, and it can return highly accurate suggestions, typically around 90-95%. What it has lacked to date is an integration with an application providing a user interface that captures feedback from its various end users including faculty, PhD students, administrators, and proxies. </div><div><br></div><div>In the last year, we have ramped up our "Academic Staff Management System" initiative or ASMS. ASMS is a homegrown PHP-based system, which provides faculty, postdocs, other academics, and their administrators a single view of key information such as appointments, educational background, board certifications, licensure, grants, and contracts. This is also an appropriate system to collect feedback on ReCiter's suggested publications.</div><div><br></div><div>For our presentation, we will demonstrate a proof of concept in which: </div><div>- ReCiter is regularly updated with data from systems of record.</div><div>- ReCiter makes suggestions for a specified group of individuals on a recurrent basis.</div><div>- These suggestions are harvested by ASMS.</div><div>- Administrative users (and eventually end users themselves) login to ASMS to provide feedback on these suggestions.</div><div>- That feedback is harvested by ReCiter and used to make increasingly accurate suggestions going forward. </div><div>- After either being validated or a period of time has elapsed with no response, we feed publication metadata to VIVO.</div><div><br></div><div>See data flow diagram: http://bit.ly/reciterASMS</div><div><br></div

A cartographic modeling approach to isopleth mapping

<p>Isopleth maps depict different types of standardized data densities, general ratios/rates, and proportions/percentages. In this study, we describe different paths each type of standardized data takes to construct isoplethic surfaces in a cartographic modeling framework. As suggested in previous research, an area-based pycnophylactic interpolator is preferred to point interpolators in isopleth mapping not only because it preserves the total volume in each aggregation unit but also because it is non-parametric and is able to incorporate ancillary data to increase the accuracy of a surface representation. Here, a general pycnophylactic method is used to generate isopleth maps of density surfaces, but a hybrid approach is proposed to address the small denominator problem that arises when mapping ratio/rate and proportion/percentage surfaces. Finally, we propose a value-by-perspective height mapping procedure to resolve the visual equalization problem associated with ratio/rate and proportion/percentage surfaces that enable one to distinguish among high rate/large denominator, high rate/small denominator, low rate/large denominator, and low rate/small denominator regions of the surface.</p

Ultrahigh-Performance Cu₂ZnSnS₄ Thin Film and Its Application in Microscale Thin-Film Lithium-Ion Battery: Comparison with SnO₂

To develop a high-performance anode for thin-film lithium-ion batteries (TFBs, with a total thickness on the scale of micrometers), a Cu₂ZnSnS₄ (CZTS) thin film is fabricated by magnetron sputtering and exhibits an ultrahigh performance of 950 mAh g^–1 even after 500 cycles, which is the highest among the reported CZTS for lithium storage so far. The characterization and electrochemical tests reveal that the thin-film structure and additional reactions both contribute to the excellent properties. Furthermore, the microscale TFBs with effective footprints of 0.52 mm² utilizing the CZTS thin film as anode are manufactured by microfabrication techniques, showing superior capability than the analogous TFBs with the SnO₂ thin film as anode. This work demonstrates the advantages of exploiting thin-film electrodes and novel materials into micropower sources by electronic manufacture methods

Three-Dimensional Cu₂ZnSnS₄ Films with Modified Surface for Thin-Film Lithium-Ion Batteries

Cu₂ZnSnS₄ (CZTS) is an important material in low-cost thin film solar cells and is also a promising candidate for lithium storage. In this work, a novel three-dimensional CZTS film coated with a lithium phosphorus oxynitride (LiPON) film is fabricated for the first time and is applied to thin-film lithium-ion batteries. The modified film exhibits an excellent performance of ∼900 mAh g^–1 (450 μAh cm^–2 μm^–1), even after 75 cycles. Morphology integrity is still maintained after repeated lithiation/delithiation, and the main reaction mechanism is analyzed in detail. The significant findings from this study indicate the striking advantages of modifying both the surface and structure of alloy-based electrodes for energy storage

Leveraging Institutional Data for Author Name Disambiguation

Author name disambiguation is a challenging problem in computer science. The problem arises from the fact that many authors share similar or identical names. Although some scholarly databases assign unique author identifiers, levels of accuracy are often unacceptable—especially for authors with common names. Existing algorithms have largely not leveraged institutional data on individual researchers. We are extending ReCiter, an agglomerative clustering algorithm for author name disambiguation, for use in publication management at our institution. The system uses available institutional data on researchers, including primary and secondary departments, history of co-investigatorships on grants and co-authorships, favored journals, and years of authors' terminal academic degrees. We are investigating the use of machine learning approaches to optimize system performance, and are planning to make the system available as a suite of freely available, open-source tools

Improved Performance of Organic Light-Emitting Field-Effect Transistors by Interfacial Modification of Hole-Transport Layer/Emission Layer: Incorporating Organic Heterojunctions

Organic heterojunctions (OHJs) consisting of a strong electron acceptor 1,4,5,8,9,11-hexaazatriphenylene hexacarbonitrile (HAT-CN) and an electron donor N,N′-di­(naphthalene-1-yl)-N,N′-diphenyl-benzidine (NPB) were demonstrated for the first time that they can be implemented as effective modification layers between hole transport layer (HTL) and emission layer in the heterostructured organic light-emitting field effect transistors (OLEFETs). The influence of both HAT-CN/NPB junction (npJ) and NPB/HAT-CN junction (pnJ) on the optoelectronic performance of OLEFETs were conscientiously investigated. It is found that both the transport ability of holes and the injection ability of holes into emissive layer can be dramatically improved via the charge transfer of the OHJs and that between HAT-CN and the HTL. Consequently, OLEFETs with pnJ present optimal performance of an external quantum efficiency (EQE) of 3.3% at brightness of 2630 cdm^–2 and the ones with npJs show an EQE of 4.7% at brightness of 4620 cdm^–2. By further utilizing npn OHJs of HAT-CN/NPB/HAT-CN, superior optoelectronic performance with an EQE of 4.7% at brightness of 8350 cdm^–2 and on/off ratio of 1 × 10⁵ is obtained. The results demonstrate the great practicality of implementing OHJs as effective modification layers in heterostructured OLEFETs

Effect of Disinfectant Exposure on Legionella pneumophila Associated with Simulated Drinking Water Biofilms: Release, Inactivation, and Infectivity

Legionella pneumophila, the most commonly identified causative agent in drinking water associated with disease outbreaks, can be harbored by and released from drinking water biofilms. In this study, the release of biofilm-associated L. pneumophila under simulated drinking water flow containing a disinfectant residual was examined. Meanwhile, the inactivation and infectivity (to amoebae) of the released L. pneumophila were studied. To simulate drinking water system conditions, biofilms were prepared under either disinfectant exposure (predisinfected biofilms) or disinfectant-free (untreated biofilms) conditions, respectively. For experiments with water flow containing a disinfectant to release the biofilm-associated L. pneumophila from these two types of biofilms, the L. pneumophila release kinetics values from predisinfected and untreated biofilms under flow condition were not statistically different (one-way ANOVA, <i>p</i> > 0.05). However, inactivation of the L. pneumophila released from predisinfected biofilms was 1–2 times higher and amoeba infectivity was 2–29 times lower than that from untreated biofilms. The higher disinfectant resistance of L. pneumophila released from untreated biofilms was presumably influenced by the detachment of a larger amount of biofilm material (determined by 16S rRNA qPCR) surrounding the released L. pneumophila. This study highlights the interaction among disinfectant residual, biofilms, and L. pneumophila, which provides guidelines to assess and control pathogen risk

Efficient Inorganic Perovskite Light-Emitting Diodes with Polyethylene Glycol Passivated Ultrathin CsPbBr₃ Films

Efficient inorganic perovskite light-emitting diodes (PeLEDs) with an ultrathin perovskite emission layer (∼30 nm) were realized by doping Lewis base polyethylene glycol (PEG) into CsPbBr₃ films. PEG in the perovskite films not only physically fills the crystal boundaries but also interacts with the perovskite crystals to passivate the crystal grains, reduce nonradiative recombination, and ensure efficient luminance and high efficiency. As a result, promoted brightness, current efficiency (CE), and external quantum efficiency (EQE) were achieved. The nonradiative decay rate of the PEG:CsPbBr₃ composite film is 1 order of magnitude less than that of the neat CsPbBr₃ film. After further optimization of the molar ratio between CsBr and PbBr₂, a peak CE of 19 cd/A, a maximum EQE of 5.34%, and a maximum brightness of 36600 cd/m² were achieved, demonstrating the interaction between PEG and the precursors. The results are expected to offer some helpful implications in optimizing the polymer-assisted PeLEDs with ultrathin emission layers, which might have potential application in see-through displays

Near-Infrared to Visible Organic Upconversion Devices Based on Organic Light-Emitting Field Effect Transistors

The near-infrared (NIR) to visible upconversion devices have attracted great attention because of their potential applications in the fields of night vision, medical imaging, and military security. Herein, a novel all-organic upconversion device architecture has been first proposed and developed by incorporating a NIR absorption layer between the carrier transport layer and the emission layer in heterostructured organic light-emitting field effect transistors (OLEFETs). The as-prepared devices show a typical photon-to-photon upconversion efficiency as high as 7% (maximum of 28.7% under low incident NIR power intensity) and millisecond-scale response time, which are the highest upconversion efficiency and one of the fastest response time among organic upconversion devices as referred to the previous reports up to now. The high upconversion performance mainly originates from the gain mechanism of field-effect transistor structures and the unique advantage of OLEFETs to balance between the photodetection and light emission. Meanwhile, the strategy of OLEFETs also offers the advantage of high integration so that no extra OLED is needed in the organic upconversion devices. The results would pave way for low-cost, flexible and portable organic upconversion devices with high efficiency and simplified processing
