title: Acceptability of Neuroscientific Interventions in Education

description: Researchers are increasingly applying neuroscience technologies that probe or manipulate the brain to improve educational outcomes. However, their use remains fraught with ethical controversies. Here, we investigate the acceptability of neuroscience applications to educational practice in two groups of young adults: those studying bioscience who will be driving future basic neuroscience research and technology transfer, and those studying education who will be choosing among neuroscience-derived applications for their students. Respondents rated the acceptability of six scenarios describing neuroscience applications to education spanning multiple methodologies, from neuroimaging to neuroactive drugs to brain stimulation. They did so from two perspectives (student, teacher) and for three recipient populations (low-achieving, high-achieving students, students with learning disabilities). Overall, the bioscience students were more favorable to all neuroscience applications than the education students. Scenarios that measured brain activity (i.e., EEG or fMRI) to assess or predict intellectual abilities were deemed more acceptable than manipulations of mental activity by drug use or stimulation techniques, which may violate body integrity. Enhancement up to the norm for low-achieving students and especially students with learning disabilities was more favorably viewed than enhancement beyond the norm for high-achieving students. Finally, respondents rated neuroscientific applications to be less acceptable when adopting the perspective of a teacher than that of a student. Future studies should go beyond the coarse acceptability ratings collected here to delineate the role that concepts of access, equity, authenticity, agency and personal choice play in guiding respondents’ reasoning.

title: Fish data for Impacts of beaver dams on low-flow hydrology and hydraulics, Knife River, Minnesota 

description: These data were collected as part of a two-year investigation into the impacts of beaver dam removal on low-flow hydrology and hydraulics in the Knife River, Minnesota, USA. These data are general surveys of fish communities in 2018 around project beaver dams which were included in the low-flow hydrology and hydraulics project (https://conservancy.umn.edu/handle/11299/220310), as well as a mark-recapture study conducted in 2019 around active and inactive beaver dams in the Knife River and French River to evaluate how beaver dams affect fish movement during the low-flow period of late summer.
description: We conducted general fish surveys in 2018 around active beaver dams selected for low-flow hydrology and hydraulics in the Knife River (https://conservancy.umn.edu/handle/11299/220310), as a component of that project was to evaluate fish movement (preference on trout species) around beaver dams. However, we learned from the general fish surveys that the project locations were not optimal for testing fish passage of dams because few trout occupied those sections of the Knife River. In 2019 we selected beaver dams all less than 1 m in height in the Knife River and the French River which sustained populations of trout. Fish were collected using backpack electrofishing gear, fish >60 mm total length where marked with visible implant elastomer (VIE) and partial fin clips, and then we recaptured fish at a later date to determine how many moved past beaver dams or natural riffles which served as a control. Fish which passed control riffles indicate normal fish movement in streams during low-flow as a comparison to fish movement past beaver dams so we could determine if beaver dams <1 m in height are barriers to fish movement.

title: Investigation of Human First-Person Motion Guidance and Perception Behavior in a Simulation Environment

description: To investigate guidance and perception behavior, an experimental system is used to observe this behavior in human subjects. The primary goal of this framework is to present a first-person guidance task to the subject, and observe the action and perception relationships generated by the subject to complete the task. The first-person perspective requires a subject to learn at both the guidance and planning levels. At the planning level to determine feasible routes based on visual cues, and at the guidance level to learn optimal relationships between control actions and visual cue motion. These learning tasks are challenges also faced by autonomous systems with first-person sensors. Understanding how humans perform guidance from this perspective is therefore directly applicable to investigating human-inspired approaches to autonomous guidance.
description: Experiments consisted of simulated first-person guidance tasks. A simulated environment allows for precise control of the available visual cues used by the subject, a precise and repeatable environment configuration, and consistent vehicle dynamic response. During experiment trials, a subject uses a controller to move a vehicle through an environment. The objective of each trial is to move from a specified start position to the goal corridor in minimal time while avoiding obstructions in the environment. While navigating through the scene, a gaze tracking device records the gaze direction of the subject. This data is used to determine which portions of the environment the subject is focusing on during specific phases of the task.

title: Serum metabolomics proton NMR data from a porcine model of burn injury

description: Background: Burn injury initiates a hypermetabolic response that leads to muscle wasting and organ dysfunction in burn patients. We examined the transition between “ebb” and “flow” in post-burn metabolism using proton nuclear magnetic resonance (1H-NMR) spectroscopy and serum from a porcine model of severe burn injury. We hypothesized serum metabolomes of porcine subjects would be distinguishable by time point, and changes in individual metabolite concentrations would characterize the shift from ebb to flow after burns.

Methods: Fifteen pigs received 40% total body surface area (TBSA) burns with additional pine bark smoke inhalation. Arterial blood was drawn at baseline (pre-burn) and every 24 hours until 72 hours post-injury or death. The aqueous portion of each serum sample was analyzed using 1H-NMR spectroscopy and metabolite concentrations were used for principal component analysis (PCA).

Results: Thirty-eight metabolites were detected in 39 samples. Thirty-one showed significant concentration changes between time points (p<0.05). PCA captured 51.6% of metabolite variability in the first two principal components and revealed clustering of samples by time point on a 2D scores plot. The first 48 hours post-burn, indicative of the shift from ebb to flow, were characterized by high concentrations of histamine, alanine, phenylalanine, and tyrosine. Later time points were characterized by rising concentrations of 2-hydroxybutyrate, 3-hydroxybutyrate, acetoacetate, and isovalerate. 

Conclusions: Post-burn metabolomes of porcine subjects were distinguishable by time point using 1H-NMR and principal component analysis. Our work identifies metabolites indicative of the transition from the ebb to flow phases of the response to burn injury, while also highlighting the accumulation of organic acids resulting from fatty acid catabolism and oxidative stress. Further studies will be required to elaborate on the post-burn metabolic pathways suggested by this analysis.
description: The data being shared are the concentrations of 38 metabolites Serum were collected at set timepoints (0 hr/pre-burn; 24 hr post-burn, 48 hr post-burn; 72 hr post-burn) from injured porcine subjects.  The injury protocol is reported in Linden et al, Shock 2015 DOI: 10.1097/SHK.0000000000000439. Serum samples were prepared for spectral analysis by filtering with a 3kDa ultracentrifuge filter. Equal parts (250 microliters) of 200 mM buffer and serum filtrate were combined with 50 microliters of internal standard 3-(trimethylsilyl)propionic acid. Spectral data were collected from a Bruker 700 MHz NMR spectrometer.  Spectra were individually processed with Chenomx Software version 7.7. The software's phasing, baseline correction, and spectral deconvolution were individually applied to each unprocessed spectrum. Spectra were fit using Chenomx's spectral library to identify and quantify metabolite concentrations (millimolar).

title: Measuring the wall depletion length of nanoconfined DNA

description: Efforts to study the polymer physics of DNA con ned in nanochannels have been stymied by a lack of consensus regarding its wall depletion length. We have measured this quantity in 38 nm wide, square silicon dioxide nanochannels for five different ionic strengths between 15 mM and 75 mM. Experiments used the Bionano Genomics Irys platform for massively parallel data acquisition, attenuating the effect of the sequence-dependent persistence length and  nite-length effects by using nick-labeled E. coli genomic DNA with contour length separations of at least 30  m (88,325 base pairs) between nick pairs. In excess of 5 million measurements of the fractional extension were obtained from 39,291 labeled DNA molecules. Analyzing the stretching via Odijk's theory for a strongly con ned wormlike chain yielded a linear relationship between the depletion length and the Debye length. This simple linear fi t to the experimental data exhibits the same qualitative trend as previously defined analytical models for the depletion length but now quantitatively captures the experimental data.

title: Bird Point Counts from Downtown Minneapolis During the 2016 Breeding Season

description: These data document species richness and abundance of the local breeding bird community in downtown Minneapolis, Minnesota. I used a conventional point count methodology (Bibby et al. 2000) to sample a total of 16 locations (or transect areas) all with a 50-meter radius. All observation periods took place between 1 June and 5 July 2016. The data can be used to derive species abundance indices and bird density. Furthermore, the data contain elements that permit more sophisticated statistical modeling such as time-depletion (removal) or distance sampling techniques.
description: The primary spreadsheet (.csv files) contains records of bird detections. The second spreadsheet summarizes sampling efforts. Two zipped shapefiles contain spatial data to describe the 16 point locations and their corresponding transect areas. A PDF file describes the field site and field methodology used for data collection. Complete details are available in the readme text file, including a list and description of all data elements.

title: Data supporting "Adverse impacts of hypoxia on aquatic invertebrates: A meta-analysis"

description: The data set on responses of aquatic invertebrates to hypoxia was created by extracting and digitizing data from published studies. The raw data were scaled to controls (i.e., high levels of oxygen).
description: Data were gathered from published, peer-reviewed studies, either copying if in tabular form or digitizing if they were plotted, using DataThief shareware which extracts data points from plots. Endpoints were measured in different ways and units, which were not immediately comparable across taxa and systems. We therefore normalized the extracted data by scaling measurements in different treatments to control, i.e. normoxic conditions.When controls were reported as averages with standard deviations, we used the value of the mean and one standard deviation for scaling. For studies testing impacts of oxygen and temperature, we scaled measured endpoints to normoxic conditions for each temperature treatment. If experiments reported results for different periods of time, we also scaled treatment results to control for each tested period.

title:  Data for "Simulation of natural alteration of iron oxides in soil: conversion of synthetic ferrihydrite to hematite without artificial dopants, observed with magnetic methods" collected at the University of Minnesota between 2016 and 2020 

description: Magnetic, pXRD and Mössbauer metadata used in the cited study on alteration of synthetic ferrihydrite. All magnetic data was collected at the Institute for Rock Magnetism on a Quantum Design MPMS and comprises magnetic susceptibility (in-phase and out-of-phase) as a function of temperature (10-300K) and frequency (1-1000 Hz), hysteresis loops measured at 5K and 300 K, and magnetic remanence data (pTRM, temperature and AF demagnetized, the "goethetite test") collected between 400 and 10 K.
description: We present the results of a new study on the conversion of pure, undoped synthetic ferrihydrite, wet-annealed at pH 6.56 and 90 ℃ without stabilizing ligands, to nanophase goethite, hematite and an intermediate magnetic phase, likely to be nanophase maghemite. Our analysis included magnetic field and temperature dependent properties and characterization by powder x-ray diffraction, Mössbauer spectra and high-resolution transmission electron microscopy.  Unlike most other studies of ferrihydrite alteration we sampled alteration products after 0.5 hours, and then in a geometric progression to 32 hours, yielding an extremely detailed examination of the earliest alteration phases. There are many similarities to the latest studies of pure ferrihydrite alteration but with a significant difference: we observe very early appearance of oriented nanophase goethite along with a soft magnetic contribution, while rhombohedral hematite crystals are formed later, as reported in the previous studies.  Our observations attest to the non-uniqueness of the magnetic enhancement process and to its strong dependence on environmental conditions, with important implications for the proposed hematite/goethite ratio as a reliable proxy for paleoprecipitation intensity.

title: A consistent and predictable commercial broiler chicken bacterial microbiome in antibiotic-free production displays strong correlations with performance

description: Defining the baseline bacterial microbiome is critical towards understanding its relationship with health and disease. In broiler chickens, numerous studies have aimed at defining the core microbiome, yet the core and its possible relationships with health and disease have been difficult to define due to lack of study power. Here, the most comprehensive microbiome-based effort to date in commercial broilers was undertaken. The primary goals of this study included understanding what constitutes core in the broiler gastrointestinal, respiratory, and barn environments; how these core players change across age, geography, and time; and which bacterial taxa correlate with enhanced bird performance in antibiotic-free flocks. Using 2,309 samples from 37 different commercial flocks within a vertically integrated broiler system, and metadata from 549 flocks within that system, the baseline bacterial microbiome was defined. The effects of age, sample type, flock, and successive flock cycles were compared, and results indicate a consistent, predictable, age-dependent bacterial microbiome, irrespective of flock. The tracheal bacterial microbiome of broilers was comprehensively defined for the first time, and interestingly, Lactobacillus was the dominant bacterial taxa in the trachea. Numerous bacterial taxa were identified which were strongly correlated with broiler chicken performance, across multiple tissues. While many positively correlated taxa were identified representing targets for future probiotic development, many negatively associated potential pathogens were identified in the absence of clinical disease, indicating subclinical dynamics occurring that impact performance. Overall, this work provides necessary baseline data for the development of effective antibiotic alternatives for sustainable poultry production.
