title:  High-Resolution Analog of Time-Domain Phonon Spectroscopy in the TEM Experimental Data and Analysis 2019-2020 

description: The behavior of coherent acoustic phonons (CAPs) as they propagate through a material is a function of the material’s optoelectronic and structural properties, making these collective oscillations a multi-faceted characterization tool. While CAPs are usually detected using transient reflectivity measurements, they have also previously been observed directly in real space using ultrafast electron microscopy (UEM). Here, we report use of UEM to measure localized CAP behavior in an amorphized and annealed GaAs specimen, and demonstrate the sensitivity of this measurement to atomic structure changes. The velocities are compared to expected values for speed of sound in order to draw conclusions about the degree of crystallinity of the specimen pre- and post-annealing. The ability to use a real-space technique to observe CAP behavior with high spatial resolution opens the door to measurements of spatially heterogeneous structural and optoelectronic properties. The data acquired in this experiment as well as analysis code are released here to enable open access to published data.

title: Data for Impacts of Nanoplastics on the Viability and Riboflavin Secretion in the Model Bacteria Shewanella oneidensis

description: Characterizing the impact of nanoplastics to organism health is important to understand the consequences of the environmental plastic waste problem. This article examines the impact of nano-polystyrene (nano-PS; 159±0.9 nm diameter) to ecologically relevant bacteria Shewanella oneidensis. Bacterial viability was evaluated using a growth-based assay. Riboflavin secretion is a critical cell function of S. oneidensis, serving as an electron mediator in anaerobic respiration and/or as a signaling molecule when the bacteria are under stress. Thus, changes in cellular function were monitored through riboflavin secretion in order to evaluate toxic responses that may not result in cell death. Under aerobic and anaerobic exposures (4, 8 or 12 h), the viability of the S. oneidensis was minimally changed as compared to the control, while the concentration of riboflavin secreted varied with exposure dose. In order to determine if this was a specific response to nanoplastic particles, opposed to a response to either particles or plastic more generally, we exposed the system to colloidal TiO2 nanoparticles and polystyrene and polyethylene thin films. We confirmed that riboflavin secretion trends were specific to nano-PS and not to these other materials, which showed no significant changes. We investigated the association of the nano-PS with ICP-MS using Pd that was chemically incorporated into the model nanoplastics. While 59.2% of the nano-PS were found in the non-cellular culture media, 7.0% and 6.6% was found associated with the loosely and tightly bound extracellular polymeric substance, respectively. There was significantly more nano-PS (10.9%) strongly associated with the cells. Taken together, we found that nano-PS had minimal impacts to viability but caused a significant change in the function of S. oneidensis that can be related to the nano-PS attached or in proximity to the bacterium. These trends are consistent between aerobic and anaerobic cultures, signifying that the stress response of S. oneidensis can be generalized between different environmental compartments. This work highlights that the association of nanoplastic materials with microorganisms may modify the cellular function that could ultimately be an impact to ecosystem health.

title: Extension distribution for DNA confined in a nanochannel near the Odijk regime

description: DNA confinement in a nanochannel typically is understood via mapping to the confinement of an equivalent neutral polymer by hard walls. This model has proven to be effective for confinement in relatively large channels where hairpin formation is frequent. An analysis of existing experimental data for Escherichia coli DNA extension in channels smaller than the persistence length, combined with an additional dataset for lambda -DNA confined in a 34 nm wide channel, reveals a breakdown in this approach as the channel size approaches the Odijk regime of strong confinement. In particular, the predicted extension distribution obtained from the asymptotic solution to the weakly correlated telegraph model for a confined wormlike chain deviates significantly from the experimental distribution obtained for DNA confinement in the 34 nm channel, and the discrepancy cannot be resolved by treating the alignment fluctuations or the effective channel size as fitting parameters. We posit that the DNA-wall electrostatic interactions, which are sensible throughout a significant fraction of the channel cross section in the Odijk regime, are the source of the disagreement between theory and experiment. Dimensional analysis of the wormlike chain propagator in channel confinement reveals the importance of a dimensionless parameter, reflecting the magnitude of the DNA-wall electrostatic interactions relative to thermal energy, which has not been considered explicitly in the prevailing theories for DNA confinement in a nanochannel.

title: Data for: Meta gene regulatory networks in maize highlight functionally relevant regulatory interactions

description: Regulation of gene expression is central to many biological processes. Gene regulatory networks (GRNs) link transcription factors (TFs) to their target genes and represent a map of potential transcriptional regulation. A consistent analysis of a large number of public maize transcriptome datasets including >6000 RNA-Seq samples was used to generate 45 co- expression based GRNs that represent potential regulatory relationships between TFs and other genes in different populations of samples (cross-tissue, cross-genotype, tissue-and-genotype, etc). While these networks are all enriched for biologically relevant interactions, different networks capture distinct TF-target associations and biological processes.

title: An urban-rural spotlight: evolution at small spatial scales among urban and rural populations of common ragweed

description: Urbanization produces similar environmental changes across cities relative to their neighboring rural environments. However, there may be high environmental heterogeneity across an urban-rural gradient. Previous research in Minneapolis, MN, USA, found mixed evidence that urban and rural plant populations of common ragweed have locally adapted, and that urban populations exhibit greater among-population divergence in ecologically-important traits. To investigate whether there are parallel patterns of urban-rural trait divergence across different urban areas, we examined trait variation across an urban-rural gradient in a second city, St. Louis, MO, USA. We used growth chamber and greenhouse common environments to investigate variation in six traits within and among 16 populations of common ragweed (eight from each urban and rural area). Urban and rural plants diverged significantly in three of five traits, with rural plants having lower percent germination, greater height and lower leaf dissection index. We also found greater variance in plant height among urban compared to rural populations, potentially driven by heterogeneity in human management practices on urban populations. Patterns of urban-rural trait divergence (e.g. in flowering time) differ substantially from those found previously in the reciprocal transplant experiment in Minneapolis, contradicting the hypothesis of parallel evolution across different metropolitan areas. The results of this study suggest that there is considerable population variation in ecologically-important traits, but that urban populations do not consistently differ from neighboring rural populations.
description: These files include data from our germination and greenhouse experiments. For the germination experiment, we recorded days to germination as well as germinants per cell, which were used to calculate percent germination. For the greenhouse experiment, we measured several phenological (initiation of reproduction, male flowering time, female flowering time) and morphological traits (height and leaf dissection). We selected these traits as they are known to be ecologically important, vary within and among populations of A. artemisiifolia, and that trait variation has a genetic basis. Initiation of reproduction was scored as the date on which a reproductive bud at the apical meristem first appeared. Male flowering time was scored as the number of days from transplanting to first observed open anther. Female flowering time was scored as the number of days from transplanting to the first visible stigma. Plant height was measured during week 7, 9, 11, and 13. After seven weeks, the third fully expanded leaf of each plant was collected to measure leaf dissection index. Leaf area and perimeter were calculated using ImageJ, and leaf dissection index was calculated by dividing leaf perimeter by twice the square root of the product of leaf area and π, or the formula: DI = Perimeter / (2√Area x π).

title: Test Networks from "Measuring the Structure of Road Networks"

description: Fig. 5 displays four base networks , 15 x 15 90° network (A0), 15 x 15 45° network (B0), and 15 x 15 30° network (C0), and 4 x 4 complete network (D0), as well as 12 network structures derived from them (three for each). As can be seen, links have been specified as five different hierarchies [1-5]. The boldness and grayness of a link indicates its hierarchy level and a bolder and darker link represents a road of a higher hierarchy. This study examines these 16 networks with proposed structural measures. (p 348 of Xie and Levinson (2007) Measuring the Structure of Road Networks)
description: The networks used in Figure 5 (Xie and Levinson (2007) Measuring the Structure of Road Networks) are in 16 simple ASCII node and link tables. The 12 derived network structures are obtained by using a simulation model called the degeneration model (Xie and Levinson (2008) The weakest link: The decline of the surface transportation network). The simulator are written in Java and named "SOUND – System for Ultraconnected Network Degeneration" (Xie and Levinson (2016).

title: Supporting data for "3D Printed Self-Supporting Elastomeric Structures for Multifunctional Microfluidics"

description: Microfluidic devices fabricated via soft lithography have demonstrated compelling applications in areas such as rapid biochemical assays, lab-on-a-chip diagnostics, DNA microarrays and cell analyses. These technologies could be further developed by directly integrating microfluidics with electronic sensors and curvilinear substrates as well as reducing the human-centric fabrication processes to improve throughput. Current additive manufacturing methods, such as stereolithography and multi-jet printing, tend to contaminate substrates due to uncured resins or supporting materials that are subsequently evacuated to create hollow fluid passages. Here we present a printing methodology based on precisely extruding viscoelastic inks into self-supporting structures, creating elastomeric microchannels and chambers without requiring sacrificial materials. We demonstrate that, in the sub-millimeter regime, the yield strength of the as-extruded silicone ink is sufficient to prevent creep under the gravitational loading within a certain angular range. Printing toolpaths are specifically designed to realize leakage-free connections between channels and chambers, T-shaped intersections and overlapping channels. The self-supporting microfluidic structures enable the automatable fabrication of multifunctional devices, including multi-material mixers, microfluidic-integrated sensors, automation components and 3D microfluidics.

title: Predictors and benefits of microhabitat selection for offspring deposition in golden rocket frogs

description: This data set originates from a field study of habitat selection by parental frogs. In many tropical frogs, offspring development and survival potentially depend on microhabitat features associated with sites that parents select for oviposition and tadpole rearing. This study investigated the importance of microhabitat features in the selection of oviposition sites versus tadpole rearing sites, as well as in determining offspring survival, in the golden rocket frog, Anomaloglossus beebei. Endemic to Guyana, this species exhibits biparental care and exclusively uses phytotelmata in bromeliads for oviposition and tadpole rearing. 

The data included here were used in model based inference to evaluate evidence for the hypotheses that (1) parents prioritize different microhabitat features in selecting phytotelmata suitable for oviposition versus tadpole rearing and (2) microhabitat selection can adaptively promote offspring survival. The dataset includes descriptions of bromeliad size, phytotelm height, leaf angle (indicative of location within the bromeliad), water volume, water temperature, dissolved oxygen concentration, and the presence/absence of potential predators and nearby conspecifics. Compared to tadpole rearing sites, the data show that oviposition sites were found in phytotelmata associated with leaves at lower angles within bromeliads and that had smaller water volumes, lower water temperatures, higher dissolved oxygen concentrations, and more crabs. Compared with unsuccessful egg clutches, successful clutches were found in phytotelmata with lower water temperatures, higher dissolved oxygen concentrations, fewer crabs, more dragonfly larvae, and more nearby conspecifics. 

These data indicate that non-random patterns of microhabitat use for oviposition sites and tadpole rearing sites in golden rocket frogs are associated with specific environmental factors that promote offspring survival through a critical stage of the animals’ complex life cycle.

The second file, "Clutch Success Data.csv", contains data associated with abiotic and biotic factors quantified for phytotelmata sites with successful clutches and phytotelmata sites with unsuccessful clutches used (i) to generate a priori logistic regression models for model comparison using Akaike's Information Criterion presented in the main text and (ii) for univariate analyses presented in Supporting Information of the referenced publication.
