title: Supporting data for Effects of Segment Length Asymmetry in Ternary Diblock Co-polymer-Homopolymer Mixtures

description: This data set contains data files and scripts to generate results reported in "Effects of Segment Length Asymmetry in Ternary Diblock Copolymer−Homopolymer Mixtures" by Yadav et al. Self-consistent field theory was used to study the effect of asymmetry between A and B statistical segment lengths on interfacial properties and phase behavior in ternary mixtures of AB diblock co-polymers, A homopolymers, and B homopolymers. We consider systems with volumetrically symmetric homopolymers and co-polymer, in which a difference between A and B statistical segment length is the only source of asymmetry between A and B monomers. The sign of the spontaneous curvature of monolayer interfaces between A- and B-rich homopolymer domains is shown to depend on the ratio of co-polymer to homopolymer chain lengths: Interfaces preferentially curve toward the component with a higher statistical segment length when the homopolymer lengths are greater than or comparable to the co- polymer length (as also found in diblock co-polymer melts) but curve away from this component when the homopolymers are much shorter than the co-polymer.

title: Phenology data for the invasive macroalga Nitellopsis obtusa (starry stonewort) in Minnesota, USA, 2017 - 2018

description: Understanding the phenology of aquatic invasive plants is critical for evaluating and predicting their ecological impacts and timing control efforts. Despite its 45-year invasion history in North America, relatively little is known about the phenology of the invasive macroalga Nitellopsis obtusa (starry stonewort). We tracked N. obtusa phenology from 2017-2018 in two Minnesota (USA) lakes representing northern and southern clusters of N. obtusa invasion in Minnesota. We measured N. obtusa biomass and counted bulbils (asexual reproductive structures) throughout the growing season and in winter, under ice. These data are provided and documented here.
description: The files include biomass, rake abundance, and bulbil data collected during each Nitellopsis obtusa phenology sampling visit from 2017-2018. There are separate files for biomass and bulbil data; bulbil data were collected in 2018 only. Please see the manuscript referenced below for a full description of the study methods and the Read Me file for a full description of the data files.

title: Comparative genomics approaches accurately predict deleterious variants in plants﻿

description: Recent advances in genome resequencing have led to increased interest in prediction of the functional consequences of genetic variants. Variants at phylogenetically conserved sites are of particular interest, because they are more likely than variants at phylogenetically variable sites to have deleterious effects on fitness and contribute to phenotypic variation. Numerous comparative genomic approaches have been developed to predict deleterious variants, but they are nearly always judged based on their ability to identify known disease-causing mutations in humans. Determining the accuracy of deleterious variant predictions in nonhuman species is important to understanding evolution, domestication, and potentially to improving crop quality and yield. To examine our ability to predict deleterious variants in plants we generated a curated database of 2,910 Arabidopsis thaliana mutants with known phenotypes. We evaluated seven approaches and found that while all performed well, the single best-performing approach was a likelihood ratio test applied to homologs identified in 42 plant genomes. Although the approaches did not always agree, we found only slight differences in performance when comparing mutations with gross versus biochemical phenotypes, duplicated versus single copy genes, and when using a single approach versus ensemble predictions. We conclude that deleterious mutations can be reliably predicted in A. thaliana and likely other plant species, but that the relative performance of various approaches can depend on the organism to which they are applied.
description: The genes and mutations information in this table were downloaded from UniProt/Swiss-Prot database (http://www.uniprot.org/) and http://www.arabidopsis.org. Single nucleotide polymorphisms (SNPs) without any known phenotype were obtained from a set of 80 sequenced A. thaliana strains (Ensembl, version 81, “Cao_SNPs”, Cao, et al., 2011). We used six approaches: LRT, PolyPhen2, SIFT 4G, Provean, MAPP, Gerp++ to predict deleterious varaints. The details can be avaible in Kono, et al., 2017 (http://www.biorxiv.org/content/early/2017/02/27/112318)

title: Hemodynamics in a giant intracranial aneurysm characterized by in vitro 4D flow MRI

description: Experimental and computational data suggest that hemodynamics play a critical role in the development, growth, and rupture of cerebral aneurysms. The flow structure, especially in aneurysms with a large sac, is highly complex and three-dimensional. Therefore, volumetric and time-resolved measurements of the flow properties are crucial to fully characterize the hemodynamics. In this study, phase-contrast Magnetic Resonance Imaging is used to assess the fluid dynamics inside a 3D-printed replica of a giant intracranial aneurysm, whose hemodynamics was previously simulated by multiple research groups. The physiological inflow waveform is imposed in a flow circuit with realistic cardiovascular impedance. Measurements are acquired with sub-millimeter spatial resolution for 16 time steps over a cardiac cycle, allowing for the detailed reconstruction of the flow evolution. Moreover, the three-dimensional and time-resolved pressure distribution is calculated from the velocity field by integrating the fluid dynamics equations, and is validated against differential pressure measurements using precision transducers. The flow structure is characterized by vortical motions that persist within the aneurysm sac for most of the cardiac cycle. All the main flow statistics including velocity, vorticity, pressure, and wall shear stress suggest that the flow pattern is dictated by the aneurysm morphology and is largely independent of the pulsatility of the inflow, at least for the flow regimes investigated here. Comparisons are carried out with previous computational simulations that used the same geometry and inflow conditions, both in terms of cycle-averaged and systolic quantities.

title: Data and code for forecasting overwintering mortality of Spathius galinae in North America 

description: From publication:
Evaluating the cold tolerance of biological control agents is often necessary to optimize their release and performance. We used field and laboratory assays to determine the cold hardiness of the parasitoid Spathius galinae Belokobylskij & Strazanac, an approved classical biological control agent of emerald ash borer (Agrilus planipennis Fairmaire) in North America. Supercooling points and lower lethal temperature of mature (cocooned) S. galinae larvae were measured in controlled cooling assays in the laboratory. Most S. galinae larvae died after reaching their supercooling point, which occurred at -25.0°C on average. Several larvae, however, initiated freezing but later eclosed, suggesting S. galinae may be partially freeze tolerant. Supercooling points were not affected by chilling rate. In the winter of 2019 – 2020, we monitored development of mature S. galinae larvae in ash segments above and beneath the snow in three locations in Minnesota, USA. Nearly 100% of S. galinae larvae died after air temperatures reached -29°C in Minnesota. Using models developed from our data, we forecast eclosion rates of S. galinae based on minimum winter temperatures across the range of ash (Fraxinus spp.) in North America. Our results indicate that S. galinae populations may suffer high overwintering mortality in areas where winter temperatures regularly decrease below -28°C, but a small portion of the population may be able to survive lower temperatures.

title: Business Retention and Expansion Aggregated Data

description: This data set aggregates 25 years of Business Retention and Expansion data to the community level. The excel document allows communities to compare their business and community landscape with others in Minnesota. Community mean responses are reported, and can be filtered based off of users' interest. This data set may be of particular interest to community and economic development practitioners.
description: These data were collected in individual business surveys over the past 25 years as part of the Extension's Center for Community Vitality Business Retention and Expansion (BRE) program, and have been aggregated to the community level for release. The BRE program has Extension Center Staff working closely with Minnesota communities to identify strategies to keep local (and even non-local) businesses located in Minnesota towns where they are. The data were collected by community volunteers meeting with the business respondents in hour-long meetings. Respondents were chosen by community leaders using different recruiting strategies. For example, the respondents could be from a randomly generated list, or someone who agreed to participate. The survey instrument went through a modification process in 2010. Some aggregation was used to reconcile the 1990-2010 and the 2010-present surveys. The shared survey instrument is the most recent and thematically it stays the same with the older version of the survey.

title: Complete Data and Analysis for: Constraining invader dominance: Effects of repeated herbicidal management and environmental factors on curlyleaf pondweed dynamics in 50 Minnesota lakes

description: Curlyleaf pondweed (Potamogeton crispus) is one of the most widespread and widely managed aquatic invasive plants in North America. Despite decades of management, the efficacy of long-term management strategies and the effects of environmental drivers on curlyleaf pondweed populations remain uncertain. To evaluate the effects of management and environmental factors on within-lake distribution and local density of curlyleaf pondweed, we collated monitoring data from aquatic plant point-intercept surveys collected by a variety of lake managers across Minnesota, USA. The goal of the study was to examine the influence of herbicide treatment, water clarity, snow depth, and ice cover duration on curlyleaf pondweed distribution and density between 2006 and 2015. The data included in this repository includes the complete dataset as a comma-separated-value file and all Program R code necessary to replicate the data processing, analysis, and visualizations used in the study.
description: The data file contains ice cover, snowcover, Secchi measurements, and herbicide management information for a set of lakes in MN where curlyleaf pondweed abundance was being measured for within the time period of 2006-2015. These data were compiled as described in the associated manuscript (https://doi.org/10.1111/fwb.13468). The Program R code will read in and summarize those data, evaluate the influence of these environmental and management parameters on abundance of curlyleaf pondweed, and create visualizations used in publication.

title: Abnormal Recovery from Acute Stress in Huntingtons Disease Mice

description: Comparisons of hypothalamic dysfunction between Huntington’s Disease (HD) patients and rodent models of HD have not always yielded similar results. Cortisol levels in HD patients have been contradictory, with reports ranging from hypo- to hypercorticoidism of morning measurements. Initial reports of major elevations in circulating corticosterone levels in the R6/2 mouse model of HD have only been followed up in one other closely related model, the R6/1 mouse, and the results were not perfectly congruent. To determine if abnormal stress hormones were a characteristic of disease, we examined diurnal and stress-induced corticosterone levels in multiple HD mouse models.

title: Analyzed Data Management Plans (DMPs) from Successful University of Minnesota Grants from the National Science Foundation, 2011-2014

description: Federal funding agencies are asking principal investigators (PIs) to specify their plans for describing, storing, securing, sharing, and preserving their research data in Data Management Plans (DMPs) included with their grant proposal. This change in sponsored research is best exemplified by the National Science Foundation (NSF) which in 2010 announced that all grants submitted after January 18th, 2011 must include a one- to two-page DMP with all new proposals.  In order to review the plans for how University of Minnesota researchers plan to manage, store, describe, protect, and share and preserve their data,  a review instrument was created and implemented by the University Libraries in the summer of 2014. Our local study of DMPs in successful NSF grant applications from January 2011 - June 2014 was opt-in by U of M PIs and the libraries collected 182 data management plans for our study, accounting for 41% of the total number of plans solicited. The deidentified data used in our analysis and our survey instrument are presented here.

title: Supporting data for "Sulfur geochemistry impacts population oscillations of wild rice (Zizania palustris)"

description: Wild rice populations decline with exposure to elevated sulfate due to production of sulfide in anoxic sediment. Using self-sustaining wild rice mesocosms, we collected data on the population response to sulfate, as well as iron and litter, which both may modify the production and availability of sulfide to plants. Wild rice also experiences natural population oscillations due to delays in release of nitrogen from decomposing litter. We use this data to investigate how sulfate-induced population declines interact with stable litter-driven population cycles. Population data was collected 2014-2019, and geochemical data (iron, sulfide, pH) was collected in 2019, after 5 years of of a factorial design treatment (sulfate, iron, litter).
description: Data consist of 1) population data from 2014-2019, including germination count, survival count, vegetative biomass, number of plants, seed biomass, number of seeds, and individual seed mass; 2) geochemical data from 2019, including sulfide, iron, and pH collected using passive equilibrium samples (peepers).
