title: Comparison of Germination and Intestinal Morphological Modification of Candidate Probiotics in Aquaculture Species

description: The application of microbial products as digestive health and immunological stimulants in animal feeds is a rapidly growing field of commercial interest and study. Aquaculture, the fastest growing sector in animal production, is experiencing broad adoption of probiotics with varying degrees of reproduced investigation. Exploring and verifying the specific dynamics of host-probiont interactions is becoming increasingly important.  Evaluation of probiotic effects and subsequent marketing in aquaculture is often delineated by microbial species. This study focused on differentiating basic growth and effects of four Bacillus spp. as direct-fed microbes, delivered as spores on extruded feed to a model aquaculture species: rainbow trout. During this 6-week study, growth metrics were tracked to compare health and performance between treatments. Germination in three distinct intestinal regions was quantified with a differential qPCR method. Modification of intestinal morphology was indicated by microvilli length. Different germination rates, spatial preference in the trout gastrointestinal tract (GIT) and morphological effects were found between candidate probionts. We outline the importance of emphasizing strain differentiation in probiotic screening and identify intestinal morphological effects between candidate probiotic strains for aquacultured finfish.

title: Dogs lap with open pumping driven by acceleration

description: Dogs lack the ability to form a seal and suck fluids into their mouth like humans, horses, and insects like mosquitos and must drink fluids using other means. They do so by lapping: a rapid extension and retraction of the tongue that brings water out of a bath and into the mouth. In this study, we measured lapping in 19 dogs and developed a physical model mimicking the dog’s tongue to elucidate the fluid mechanism of dog lapping. The results demonstrated that tongue size governed lapping frequency. In addition, it suggested that dogs curl the tongue to create a larger liquid column so they can drink more water each lap. Comparing lapping in dogs and cats revealed that, despite similar morphology, these carnivores lap in different physical regimes: a high-acceleration regime for dogs and a low-acceleration regime for cats.

title: Growth and survival relationships of 71 tree species with nitrogen and sulfur deposition across the conterminous U.S.: Data and R code

description: Atmospheric deposition of nitrogen (N) influences forest demographics and carbon (C) uptake through multiple mechanisms that vary among tree species. Prior studies have estimated the effects of atmospheric N deposition on temperate forests by leveraging forest inventory measurements across regional gradients in deposition.  However, in the United States (U.S.), these previous studies were limited in the number of species and the spatial scale of analysis, and did not include sulfur (S) deposition as a potential covariate.  Here, we present a comprehensive analysis of how tree growth and survival for 71 species vary with N and S deposition across the conterminous U.S. Our analysis of 1,423,455 trees from forest plots inventoried between 2000 and 2016 reveals that the growth and/or survival of the vast majority of species in the analysis (n=66, or 93%) were significantly affected by atmospheric deposition.  Species co-occurred across the conterminous U.S. that had decreasing and increasing relationships between growth (or survival) and N deposition, with just over half of species responding negatively in either growth or survival to increased N deposition somewhere in their range (42 out of 71). Averaged across species and conterminous U.S., however, we found that an increase in deposition above current rates of N deposition would coincide with a small net increase in tree growth (1.7% per Δ kg N ha-1 yr-1), and a small net decrease in tree survival (-0.22% per Δ kg N ha-1 yr-1), with substantial regional and among-species variation. Adding S as a predictor improved the overall model performance for 70% of the species in the analysis. Our findings have potential to help inform ecosystem management and air pollution policy across the conterminous U.S., and suggest that N and S deposition have likely altered forest demographics in the U.S.

title: Concrete Crack Conglomerate Dataset

description: <p>This dataset is the conglomeration of the cataloged crack
datasets from the literature, making an extremely diverse crack dataset. There
were over 10,995 images which have been merged from CFD (Shi, Cui, Qi, Meng,
& Chen, 2016), Crack500 (Yang et al., 2020), CrackTree200 (Zou, Cao, Li,
Mao, & Wang, 2012), DeepCrack (Y. Liu, Yao, Lu, Xie, & Li, 2019), Eugen
Miller (Yang et al., 2020), GAPs (Eisenbach et al., 2017), Rissbilder (Yang et
al., 2020), non-crack (Dorafshan, Thomas, & Maguire, 2018), and Volker
(Yang et al., 2020). The majority of pixels were in the background class at
97.2%, and a little over 2.8% were in the crack class. This was expected, since
cracks take up only thin lines of space on most images. The images were resized
to 512x512 for training and testing the DeeplabV3+ model. The original and
resized images are included. The data was split 90% training, and 10% testing
by randomly sorting the data. After training with the DeeplabV3+ model (DOI: 10.7294/16628596),
we were able to receive approximately 70% accuracy for detecting concrete
cracks in the image. More details of the training, the results, the dataset,

title: Chicago Elections Project

description: The Chicago Elections Project is a digital history collaboration working to expand access and provide interpretation on the electoral and political history of the city. The Chicago Elections Project is a large-scale digitization and visualization project that will allow the public, journalists, and researchers to understand the political history of the city in new ways. It will enable the telling of stories about the neighborhood and city-wide electoral contests that shaped public policy in Chicago and Illinois over more than a century. 

For more information, visit the Chicago Elections Project website: http://www.chicagoelectionsproject.com

The data in the Chicago Elections Project was created by the Chicago Board of Elections in the course of administering the city’s elections.  The collection presented here seeks to make the digitized archival materials and data visualizations accessible for further and future public research. These materials include images of the city’s ledgers which contain tabulated election results (.jpg files); the project’s excel spreadsheets that transcribe election results from the city’s ledgers (.xlxs files); images of the Chicago Board of Elections’ ward and precinct maps (.jpg files); and digital map materials created from these images (shapefile bundles). The files are organized first by year and then election type; see the ReadMe file for a detailed outline and description of files included in the data collection.

Since 1923, there have been 50 wards in the City of Chicago.  Each ward consists of a variety of precincts.  From 1889 to 1923, there were 35 wards.  Municipal elections featuring the contest for mayor are generally held every four years in April of years preceding Presidential elections, eg 1923, 1927, 1931 etc.  These are preceded by February primaries.  Even numbered years feature federal Congressional elections and State Senate and State House elections in November, eg 1990, 1992, etc.  These are preceded by primaries in the spring.

title: Rough wall boundary layer measurements to accompany the paper "Characteristics of the Pressure Fluctuations Generated by Turbulent Boundary Layers over Rough Surfaces"

description: This data set accompanies the paper 'Characteristics of the Pressure Fluctuations Generated by Turbulent Boundary Layers over Rough Surfaces', Joseph L., Molinaro N., Devenport W. and Meyers T., Journal of Fluid Mechanics, in press, 2019. Most flows of practical interest are turbulent in nature, typically occurring next to a rigid surface such as a submarine hull or aircraft wing. This boundary layer now is of engineering importance because its pressure fluctuations are the source of unwanted structural vibrations and undesired acoustic noise. From a purely scientific perspective, it is useful to study the turbulent pressure fluctuations in order to learn more about the workings of the region of the flow closest to the surface.
The present data was collected with the goal of exploring the nature of the rough-wall turbulent boundary layer through wind tunnel experiments. Experiments were carried out in high Reynolds number turbulent boundary layers over rough surfaces of diverse geometries. Roughness configurations varied in element height, distribution (random versus ordered), shape, and spacing. Rough surfaces comprising of two superposed element geometries were also tested. All flows were free of transitional effects with momentum thickness Reynolds numbers upwards of 40000 and boundary layer thickness to roughness height ratios above 73. The data include velocity and pressure fluctuations, and the boundary layer parameters derived from these.

title: A Revised Measure of Ely’s Conditions of Change: Initial Psychometric Properties of the Implementation Profile Inventory II

description: Perceptions of conditions that influence implementation of innovations are important measures of success and can serve as a planning guide for the instructional designer (Ely, 1990a, 1990b, 1999a, 1999b; Ensminger & Surry, 2002; Ensminger, 2005). The IPI-II is a revised scale (Ensminger & Surry, n.d.), designed to measure users’ perceptions of the importance of Ely’s (1990a) eight conditions of change. Confirmatory Factor Analysis (CFA) was conducted to determine the psychometric properties and underlying factor structure of the IPI-II in a sample of 252 university faculty and staff. Results from comparing three alternative factor structure models provide evidence supporting Ensminger et al.’s (2004) hypothesized four-factor structure for the IPI-II along with evidence of excellent construct validity and internal consistency. More importantly, the results provide evidence supporting a better fitting five-factor solution for the IPI-II. Expanding the number of higher-level factors from four to five and reconceptualizing the fifth factor labeled to address the condition of Dissatisfaction with Status Quo, may improve the measurement model. Recommendations are offered to facilitate the process of developing a new set of indicator measures to achieve a stable, well-defined solution for the structure of the IPI-II.This study represents the first psychometric evaluation of the IPI-II and the first confirmatory study in the development cycle of the Implementation Profile Inventory.

title: SPHK-JCIM-MARCH2019-STRUCTURE-DOCKING-FILES

description: Alterations in cellular signaling pathways are associated with multiple disease states including cancers and fibrosis. Current research efforts to attenuate cancers, specifically lymphatic cancer, focus on inhibition of two sphingosine kinase isoforms, sphingosine kinase 1 (SphK1) and sphingosine kinase 2 (SphK2). Determining differences in structural and physicochemical binding site properties of SphKs is attractive to refine inhibitor potency and isoform selectivity. This study utilizes a predictive in silico approach to determine key differences in binding sites in SphK isoforms in human and mouse species. Homology modeling, molecular docking of inhibitors, analysis of binding pocket residue positions, development of pharmacophore models, and analysis of binding cavity volume were performed to determine isoform- and species-selective characteristics of the binding site and generate a system to rank potential inhibitors. Interestingly, docking studies showed compounds bound to mouse SphK1 in a manner more similar to human SphK2 than to human SphK1, indicating that SphKs in mice have structural properties distinct from humans that confounds prediction of ligand selectivity in mice. Our studies aid in the development and production of new compound classes by highlighting structural distinctions and identifying the role of key residues that cause observable, functional differences in isoforms and between orthologues.

title: Supplementary Material: Carnivore-Livestock Conflicts in Chile: Evidence and Methods for Mitigation

description: Abstract: Human population growth and habitat loss have exacerbated human-wildlife conflicts worldwide. We explored trends in human-wildlife conflicts (HWCs) in Chile using scientific and official reports to identify areas and species with higher risk of conflicts and tools available for their prevention and mitigation. The puma (Puma concolor) was considered the most frequent predator, however, fox (Lycalopex spp.) and free-ranging or feral dog (Canis familiaris) attacks were also common. Our results suggest that the magnitude of puma conflicts may be overestimated. Domestic sheep (Ovis spp.) and poultry (Galliformes) were the most common species predated. Livestock losses were widespread across Chile, but were highest in San Jose de Maipo, located in central Chile, Cochrane, La Union, and Lago Verde, in south Chile, municipalities. Guardian dogs and the livestock insurance, as a part of the Agriculture Insurance of Chile, were identified as the most promising tools to mitigate HWCs, short- and mid-term, respectively. However, longer-term strategies should focus on improving livestock management through extension (i.e. farmer education) programs for local communities. In Chile, HWCs negatively impact small farmers and wild-carnivore populations. An inter-institutional, interdisciplinary strategy, integrating input from government, non-governmental organizations, farmers, and academia, is needed to achieve effective carnivore conservation in the long-term.

title: Data from Adult piping plover habitat selection varies by behavior

description: <p>These data are used piping plover locations, and random locations, dispersed throughout Fire Island and Westhampton Island, breeding sites for piping plover. We recorded individual locations of birds with coordinate geometry by first recording an observer’s location using a Trimble GPS unit (Trimble Geospatial, Sunnyvale, CA, USA), and offsetting that location with an azimuth from a compass and a distance from a Nikon 8397 Aculon Laser Rangefinder (Nikon, Minato, Tokyo, Japan; Robinson et al. 2020a). Each piping plover location has an associated behavior, and we assigned a behavior to each adult based on observed behavior at first encounter and later classified all behaviors into two categories: parental and non-parental. Parental behaviors included incubating nests, broken wing displays, defensive peeping, and brooding or attending to chicks, whereas non-parental behaviors included foraging, aggression, territorial, roosting, loafing, and courtship. Each location also has a variety of continuous landscape variables associated with it, at multiple scales. Scales were defined by analyzing adult movement patterns, and each landscape variable was ranked with univariate resource selection models to determine the scale that best represented piping plover habitat selection. We then summarized each variable within a circle with the radius of the best fit scale, and used that in a habitat selection model.</p>

title: Classification Map of Smallholder Forest Plantations in Andhra Pradesh, India

description: <p>This study's objective was to develop a method by which
smallholder forest plantations can be mapped accurately in Andhra Pradesh,
India, using multitemporal visible and near-infrared (VNIR) bands from the
Sentinel-2 MultiSpectral Instruments (MSIs). Conversion to cropland, coupled
with secondary dependencies on and scarcity of wood products, has driven the
deforestation and degradation of natural forests in Southeast Asia.
Concomitantly, forest plantations have been established both within and outside
of forests, with the latter (as contiguous blocks) being the focus of this
study. Accurately mapping smallholder forest plantations in South and Southeast
Asia is difficult using remotely sensed data due to the plantations’ small size
(average of 2 hectares), short rotation ages (4-7 years for timber species),
and spectral similarities to croplands and natural forests. Cloud-free
Harmonized Landsat Sentinel-2 (HLS) S10 data was acquired over six dates, from
different seasons, over four years (2015-2018). Available in situ data on
forest plantations was supplemented with additional training data resulting in
2,230 high-quality samples aggregated into three land cover classes: nonforest,
natural forest, and forest plantations. Image classification used random
forests on a thirty-band stack consisting of the VNIR bands and NDVI images for
all six dates. The median classification accuracy from the 5-fold
cross-validation was 94.3%. Our results, predicated on high-quality training
data, demonstrate that (mostly smallholder) forest plantations can be separated
from natural forests even using only the Sentinel-2 VNIR bands when
multitemporal data (across both years and seasons) are used.</p>
