    Data associated with: Retrospective land surface model simulations of Western Tropical South America

    No full text
    Western Tropical South America (WTSA) is a climatically and hydrologically diverse region that is underserved by in situ meteorological and hydrological monitoring networks. In this context, retrospective simulations performed with advanced land surface models (LSMs) can provide a valuable complement to historical observation networks, providing consistent and physically-based estimates of land surface hydrologic states and fluxes. This data archive contains the output of simulations performed with the Noah MultiParameterization (Noah-MP) LSM and the Hydrological Modeling and Analysis Platform (HyMAP) for a region that encompasses WTSA from the Pacific Coast through the Western Amazon. The period covered by these simulations is January 2002 - September 2019, and the primary purpose of the dataset has been to develop an environmentally-informed Malaria Early Warning System (MEWS) for the region. In presenting these results in a public archive we aim to preserve and share the results of these simulations, which serve as a basis for several reports and publications on WTSA hydrology and climate. The archive is also intended to serve as a resource for organizations working in the region that might lack the computing capacity required to generate such computationally intensive simulations

    Data associated with publication: Dichlorinated dithienylethene-based copolymers for air-stable n-type conductivity and thermoelectricity

    No full text
    The data consists of spreadsheets and other forms of raw data for the different kinds of characterizations reported in the manuscript, and are the basis for the figures shown in the manuscript. The highest level of folders is labelled according to the physical property being measured or the technique being used. Where subfolders are present, they are labelled according to the compound being characterized. From the publication abstract: Two donor–acceptor (D–A) polymers are obtained by coupling difluoro‐ and dichloro‐substituted forms of the electron‐deficient unit BDOPV and the relatively weak donor moiety dichlorodithienylethene (ClTVT). The conductivity and power factors of doped devices are different for the chlorinated and fluorinated BDOPV polymers. A high electron conductivity of 38.3 and 16.1 S cm−1 are obtained from the chlorinated and fluorinated polymers with N‐DMBI, respectively, and 12.4 and 2.4 S cm−1 are obtained from the chlorinated and fluorinated polymers with CoCp2, respectively, from drop‐cast devices. The corresponding power factors are 22.7, 7.6, 39.5, and 8.0 µW m−1 K−2, respectively. Doping of PClClTVT with N‐DMBI results in excellent air stability; the electron conductivity of devices with 50 mol% N‐DMBI as dopant remained up to 4.9 S m−1 after 222 days in the air, the longest for an n‐doped polymer stored in air, with a thermoelectric power factor of 9.3 µW m−1 K−2. However, the conductivity of PFClTVT‐based devices can hardly be measured after 103 days. These observations are consistent with morphologies determined by grazing incidence wide angle X‐ray scattering and atomic force microscopy

    Data associated with the publication: Key factors to facilitate locally driven family planning programming: A qualitative analysis of urban stakeholder perspectives in Africa and Asia

    No full text
    There has been greater recognition of the importance of country ownership in global health and development. However, operationalising country ownership to ensure the scale up and sustainability of proven interventions remains elusive at best. To address this challenge, the authors undertook a thematic analysis of interviews collected from representatives of local governments, public health systems, and communities in poor urban areas of East Africa, Francophone West Africa, India, and Nigeria, supported by The Challenge Initiative (TCI), aiming to rapidly and sustainably scale up evidence-based reproductive health and family planning solutions. The main objective of the study was to explore critical elements needed for implementing and scaling evidence-based family planning interventions. The research team conducted thematic analysis of 96 stories collected using the Most Significant Change (MSC) technique between July 2018 and September 2019. After generating 55 unique codes, the codes were grouped into related themes, using TCI’s model as a general analytical framework. Five key themes emerged: (1) strengthening local capacity and improving broader health systems, (2) shifting mindsets of government and community toward local ownership, (3) institutionalizing the interventions within existing government structures, (4) improving data demand and use for better planning of health services, and (5) enhancing coordination of partners. While some themes feature more prominently in a particular region than others, taken together they represent what stakeholders perceive to be essential elements for scaling up locally-driven health programmes in urban areas of Africa and Asia

    Data and code associated with the publication: Characterization of geographic mobility among participants in facility- and community-based tuberculosis case finding in urban Uganda

    No full text
    This dataset is an anonymized subset of the data collected by the STOMP-TB study (A Comprehensive Snapshot of Tuberculosis Transmission in an Urban Ugandan Community). The dataset includes records from: 1. patients who were diagnosed with pulmonary TB through routine care at one of four health facilities in Kampala, Uganda; 2. control patients who underwent TB evaluation with a negative result at the same facilities; 3. patients who were diagnosed with TB during a community-based active case finding campaign; and 4. control individuals who tested negative for TB during a community-based active case finding campaign. The included variables were used for analysis of geographic mobility and its association with TB disease in the publication “Characterization of geographic mobility among participants in facility- and community-based tuberculosis case finding in urban Uganda” by KO Robsky et al. (PLOS One, published May 14, 2021)

    Data and software associated with the publication “De novo learning versus adaptation of continuous control in a manual tracking task”

    No full text
    This collection contains the raw data and analysis code to reproduce the figures in the above publication. We sought to test whether human participants were capable of building controllers de novo to counter either a rotation or a mirror-reversal of visual feedback. To do so, we trained participants to counter these perturbations in a point-to-point reaching task and assessed their control capabilities in a sum-of-sinusoids tracking task. We analyzed their reaching trajectories using a frequency-domain system identification approach. The data were collected in the BLAM Lab at Johns Hopkins University. A README.md file is included in every .zip file with instructions on how to run the analyses. Each .zip file can be run independently of the others

    Data associated with the publication: Characterizing the roles of biogeochemical cycling and ocean circulation in regulating marine copper distributions

    No full text
    Despite many improvements in understanding the role of copper (Cu) in microbial metabolism, we still lack the understanding of its biogeochemistry in the ocean. One difficulty is how to interpret the linear depth profiles of dissolved Cu in the ocean. Additionally, the relationships between Cu and macronutrients in the global ocean have not been well characterized. Examining the relationships between observed Cu, PO43–, and Si, we found that Cu was more correlated with Si than PO43– in the global ocean. In our model, both biogeochemical cycling and internal circulation are important for explaining global marine Cu distributions. Our modeling results suggest a deep remineralization of Cu, which is consistent with previous lab results. Furthermore, the modeling results indicate that the uptake of Cu in the Southern Ocean is substantially higher than that in non-Southern Oceans. These results lead us to hypothesize that phytoplankton such as diatoms living in the Southern Ocean dominate marine Cu distributions
