City of Seattle, Seattle Public Utilities, Knotweed Control 2010-current, Cedar River Municipal Watershed, King County, WA
The City of Seattle’s Cedar River Municipal Watershed is managed to support and supply clean drinking water to the greater Seattle area. The watershed covers 91,000 acres, hosts a rich diversity of plants, animals, and habitats, and is owned by the City of Seattle. In 1999, the noxious weed knotweed was detected in the watershed and control was limited to manual and mechanical methods due to an herbicide moratorium intended to prevent broadcast spraying of roadside vegetation. These manual control methods were largely unsuccessful and impractical for controlling acres of knotweed growing in remote locations of the watershed. In 2010, Seattle Public Utilities passed the first ordinance through Seattle City Council to approve the limited use of imazapyr to control knotweed in the watershed for three years. Successive knotweed ordinances have been passed, allowing for herbicide control of knotweed in the watershed from 2010-current. The reports included in this package are provided to Seattle City Council annually as a requirement of the ordinance. The data table provides the control history since the passage of the first ordinance and includes information about patch size and amount of imazapyr used. This data package will be updated annually with ongoing control efforts.

Current Harmonics Minimization of PMSM Based on Iterative Learning Control and Neural Networks: Motor Data
<p>The provided motor data corresponds to an electrical machine with 24 stator slots and 16 poles. As is common in electrical machines, this motor generates unwanted flux and current harmonics. However, the accompanying paper presents an effective solution to suppress these harmonics through the combined use of Iterative Learning Control (ILC) and Neural Networks (NNs).</p> <p>The ILC method demonstrates proficient compensation for harmonics during operations with constant speed and current reference values. Additionally, Neural Networks are trained with data derived from ILC, proving to be highly effective in suppressing harmonics even during transient operation. The simulation model used in the study is based on flux and torque maps, dependent on dq-currents and the electrical angle. These maps are obtained from Finite Element Method (FEM) simulations of an interior permanent magnet synchronous machine (IPM) and are openly published here, intended to facilitate other researchers in making direct comparisons with their own methodologies.</p> <p>Simulation results presented in the paper confirm that the integration of ILC and NNs leads to superior elimination of current harmonics during transient operations compared to using ILC alone.<br> If you use the provided maps and motor data, kindly cite the associated paper for reference: https://doi.org/10.3390/machines11080784, https://www.mdpi.com/2075-1702/11/8/784</p>

Model Data for Dynamic Controls on the Asymmetry of Mouth Bars: Role of Alongshore Currents
<p>The Model dataset is exported and integrated from Delft3D numerical setup files and results by using the Quickplot module, which is used in the manuscript entitled <strong>"Dynamic Controls on the Asymmetry of Mouth Bars: Role of Alongshore Currents"</strong>. </p> <p>In terms of the Delft3D setup files, please see the zipped file "Delft3D_setup_files.zip", including the run 2-A0.75 and run 4-N0.075.</p> <p>In terms of model result dataset, each folder is organized based on the unique RunID assigned to the Delft3D simulations, as detailed in the Table 1 in the main text of the manuscript. Given the employment of multiple decomposition domains within the model, the numerical results are exported individually for each domain. To facilitate the analysis of "bulk" data, encompassing three dimensions (two in horizontal space and one in time), all single domains are intergrated by Matlab script into three comprehensive data files. The data files with the ".mat" extension can be directly opened and loaded in MATLAB. The prefixes of the MAT-files are as follows:</p> <ul> <li>The "bedlevel_daily_*.mat" files contain daily map data of the bed level (ZZ) spanning 74 simulation days (73 time steps in total). This data is used to calculate metrics for assessing mouth bar asymmetry.</li> <li>The "map_u_c_h_day5_*.mat" files represent map data (recorded every 15 minutes, 97 time steps in total) including depth-averaged velocity (u), suspended sediment concentration (c), water depth (h), bed level (bl), and sediment flux (qs) after t=5 hydrodynamic days. This data is used to analyze sediment plume and currents during the period of the initial formation of mouth bars, providing predictive insights. <ul> <li>The "map_u_c_h_day5_include_channel_*.mat" files serve a unique purpose in visualizing the flow vectors (u) and the suspended sediment concentration (c) at the river mouth, incorporating the extended channel. We present two specific scenarios: "2-A0.75" and "4-N0.075," which directly correlate with the cases illustrated in Figure 8 of the manuscript, facilitating a more comprehensive understanding and analysis.</li> </ul> </li> <li>The "map_h_u_qs_afterday74_*.mat" files contain hourly map data comprising bed level (h), water depth (d), depth-averaged velocity (U for instantaneous and v for tidally-averaged), and suspended sediment flux (QS for instantaneous and q for tidally-averaged) within a tidal cycle of 12-hr semidiurnal tide (13 time steps). This data is utilized to visualize and extract distributary channels after 10 morphological years of evolution. The MATLAB code for extracting channels follows the GRL paper <a href="https://doi.org/10.1029/2018GL080447">(Gao et al., 2018)</a> and JGR-ES paper <a href="https://doi.org/10.1029/2017JF004584">(Gao et al., 2019)</a>, also seen in <a href="https://github.com/weilungao/ShorelineExtraction">https://github.com/weilungao/ShorelineExtraction</a>. For added convenience, the comprehensive integration packages, titled 'ShorelineExtraction-master' and 'DeltaicDistributaryNetwork-main', containing essential Matlab codes, have been pre-uploaded to this dataset.</li> </ul> <p>The MATLAB-compatible '.m' code files enable direct opening and data processing. Simply execute the files in sequential order, prefixed "step0-4", for seamless data manipulation. The default list for 32 simulation cases is given by "file_case_index_group.txt". Individual cases can be processed separately by modifying the loading script within the code files as needed.</p> <p>Tip: To ensure the smooth execution of the script, kindly place all downloaded single files or packaged folders (once unzipped but keep the subdirectories) within the same directory. </p>

Data from: Na+/K+ pump interacts with the h-current to control bursting activity in central pattern generator neurons of leeches
The dynamics of different ionic currents shape the bursting activity of neurons and networks that control motor output. Despite being ubiquitous in all animal cells, the contribution of the Na+/K+ pump current to such bursting activity has not been well studied. We used monensin, a Na+/H+ antiporter, to examine the role of the pump on the bursting activity of oscillator heart interneurons in leeches. When we stimulated the pump with monensin, the period of these neurons decreased significantly, an effect that was prevented or reversed when the h-current was blocked by Cs+. The decreased period could also occur if the pump was inhibited with strophanthidin or K+-free saline. Our monensin results were reproduced in model, which explains the pump's contributions to bursting activity based on Na+ dynamics. Our results indicate that a dynamically oscillating pump current that interacts with the h-current can regulate the bursting activity of neurons and networks.
