Supporting Data for Spectral Engineering with Quantum Dot Films for Enhanced Lettuce Growth
(2025-05-29) Loh, Kristine Q; Eylands, Nathan J; Ferry, Vivian E; Kortshagen, Uwe R; kortshagen@umn.edu; Kortshagen, Uwe R.; Kortshagen Group
To improve crop yields without the added cost of supplementary lighting, passive spectral manipulation shifts sunlight into critical wavebands for plant growth. Quantum dot (QD) films shift higher energy photons to lower energies, serving as tunable sunlight filters, but are understudied in this application space. Herein, we identify QD film properties to pro-mote lettuce growth. By simulating films with nine different nontoxic QDs, we calculate a concentration-dependent lettuce yield improvement of up to 45%. QDs that strongly absorb blue/green light and downshift this light to red/far-red wavebands result in the highest lettuce yield enhancements. Despite this strong absorption, we find that QD films can be utilized broadly in the United States. Contrary to common intuition, increasing the photoluminescence quantum yield or film outcoupling efficiency does not further increase lettuce yield, indicating that filtered absorption is the most important factor in design. This study points to the need for more directed investigation into QD films for increasing plant growth.

2025 Duluth Watersheds Geologic & Fluvial Geomorphic Information
(2025-05-16) Bugno, Benjamin; benbugno@gmail.com; Bugno, Benjamin; Gran Research Lab, University of Minnesota Duluth
Uplift or base level fall in bedrock rivers can produce knickpoints (waterfalls) that propagate upstream to adjust the elevation of the longitudinal profile to reach a steady state. The migration rate of knickpoints is influenced by factors like local channel slope, drainage area (a proxy for discharge), and substrate erodibility. This dataset was used to investigate the geologic controls on bedrock landscape evolution following base level fall. Three map packages for three watersheds in the Duluth area (Amity Creek, Lester River, Mission Creek) are included in this dataset. A geologic map (“ExposureMap”) for each watershed was created to determine what the substrate control was on fluvial erosion. Point files contain information relating to stream characteristics (channel elevation, upstream area, distance from mouth, channel slope, modeled Erosion Index (“Stream Power”)), location of knickpoints (spikes in slope/Stream Power), and substrate erodibility in the channel (uniaxial compressive strength, fracture density, fracture intensity). Additional raster datasets include a Digital Elevation Model (DEM) of the watershed and a hillshade map.
Data from an online experiment testing the effect of instructions to "be creative" on 5- to 6-year-old children's creativity, and the contribution of executive function skills
(2025-05-16) Vaisarova, Julie; Carlson, Stephanie, M; smc@umn.edu; Carlson, Stephanie, M.
Although executive functions (EF; controlled, top-down cognitive processes) may seem antithetical to creative thinking, research with adult populations suggests that top-down processes actually support some components of the creative process. When adults are asked to "be creative," those with stronger executive skills show a larger creativity boost, suggesting they use these skills to reflect on and modify their ideation (Nusbaum et al., 2014). Whether children use their EF skills similarly, however, remains unclear. This record contains data from a study published in Psychology of Aesthetics, Creativity, and the Arts, which investigated whether young children use EF to deliberately modify their creative idea-generation. 148 typically developing 5- to 6-year-olds from a midwestern region of the United States (50% female, mostly White and from high-income homes) took part in the study over Zoom. Children completed behavioral tasks to assess their verbal skills (Stanford-Binet verbal routing subtest; Roid, 2005) and executive functions (Backward Digit Span and Hearts and Flowers; Wechsler, 2003; Davis & Pratt, 1995; Davidson et al., 2006). They also completed the Alternate Uses Task (AUT) -- a creative idea-generation (divergent thinking) task in which they generated possible uses for two objects (string and box). Children were randomly assigned to one of two instructions for the AUT: to come up with "as many ideas as you can" or "ideas that are creative." Details of the study procedure can be found in the manuscript "Can young children control their creativity? Examining the role of executive function in modifying children’s creative processes" published in Psychology of Aesthetics, Creativity, and the Arts. This record contains the de-identified data and R code needed to replicate the analyses reported in the manuscript.
A genome-wide association study on resistance to iron deficiency chlorosis in soybean using whole genome resequencing data
(2025-05-12) Espina, Mary Jane C; Stupar, Robert M; Lorenz, Aaron J; espin164@umn.edu; Espina, Mary Jane; University of Minnesota Soybean Breeding and Genetics Lab
Iron deficiency chlorosis (IDC) is a nutritional stress prevalent in high pH and high calcium soils, significantly reducing soybean productivity. This study aimed to identify genetic variants associated with IDC resistance using high-resolution markers. In this research, we analyzed 426 G. max accession using 1.4 M markers, incorporating comprehensive IDC phenotyping across four environments and accounting for spatial field variation. Additionally, we examined the phylogenetic relationships within the panel and the distribution of IDC resistance. Our analysis identified six significant loci associated with IDC resistance, including three previously mapped regions and three novel associations. Furthermore, we found one association in chromosome 13 for IDC recovery, located near a previously mapped maturity locus. Notably, one of the significant hits for IDC resistance found in chromosome 5 was co-localized within a previously fine-mapped 75 kb region. Within this region, we conducted candidate locus association and analyzed the effects of different haplotype combinations involving transposable elements and TATA box insertions for potential epistatic interactions. We found that lines carrying the ‘Fiskeby III’ type alleles with the significant SNP, L1-13, and TATA insertions exhibited significantly lower IDC scores than those carrying the Wm82 type alleles. We also validated a putative candidate gene using CRISPR-Cas9 knock-out experiments but found no significant phenotypic differences between the knock-out line and the wild type. Finally, these findings reinforce the importance of chromosome 5 QTL in IDC resistance. However, our results suggest that the genetic mechanism is very complex for this trait, warranting further investigation to fully understand the underlying genetics behind this QTL.

Supporting Data for Block Copolymer Molecular Design to Address Practical Limitations to Recycling Polyolefin Blends
(2025-05-12) Cui, Shuquan; Jeong, Daun; Shi, Yukai; Jahan, Nusrat; Lodge, Timothy P; Bates, Frank S; Ellison, Christopher J; cellison@umn.edu; Ellison, Christopher J; Department of Chemical Engineering and Materials Science
Plastics offer innumerable societal benefits but simultaneously contribute to persistent environmental pollution, dominated by polyethylene (PE) and isotactic polypropylene (iPP). Melt blending and reformulating post-consumer PE and iPP into useful materials presents a promising recycling approach. However, such repurposed plastics are generally mechanically inferior due to an inability to efficiently separate polyolefins in mixed waste streams; phase separation of PE and iPP results in brittleness as a consequence of poor interfacial strength. Recently we demonstrated that a small amount (1 wt%) of a poly(ethylene)-block-poly(ethyl ethylene-ran-ethylene)-block-poly(ethylene) (EXE) triblock copolymer, synthesized by low-cost anionic polymerization of 1,3-butadiene followed by solution hydrogenation, restores tensile toughness to levels equivalent to virgin polyolefins. Unfortunately, low-temperature solvent insolubility of EXE, driven by crystallization of the E blocks containing 1.5 ethyl branches per 100 backbone repeat units (EB), presents a challenge for industrial hydrogenation. Comparable toughness (ca. > 400% strain at break) was achieved in the present work with EB ranging from 1.5 to 6.5, accompanied by reduced EXE crystallinity and dissolution in cyclohexane down to room temperature at the highest EB content. This remarkable toughening behavior is attributed to a synergy between chain entanglements between the E end blocks and semicrystalline PE homopolymer and formation of E block “crystal nodules” that prevent chain pullout, along with topological constraints between the X loops and semicrystalline iPP. Our findings overcome barriers to commercial production of EXE with existing industrial facilities, providing a cost-effective strategy for recycling PE and iPP.
Supporting data for The fitness effects of outcrossing distance depend on parental flowering phenology in fragmented populations of a tallgrass prairie forb
(2025-05-08) Waananen, Amy; Ison, Jennifer L; Wagenius, Stuart; Shaw, Ruth G; waana001@umn.edu; Waananen, Amy
The phenomena of isolation-by-distance and isolation-by-time shape mating patterns and population genetic processes, such as inbreeding and outbreeding depression, which influence progeny fitness. However, the effects of parental isolation in time on offspring fitness remain understudied, especially in combination with isolation-by-distance. We planted offspring from a common garden experiment involving 13 populations of the tallgrass prairie forb Echinacea angustifolia into a prairie restoration and tracked their fitness over 16 years. Parental source populations were up to 9 km apart, and flowering asynchronies spanned up to 13 days. Using Aster life-history analysis, we assessed how interparent distance and asynchrony affected offspring fitness. This dataset includes offspring fitness data (cumulative number of flowering heads produced), data on parental individuals, including source population proximity and asynchrony, and R code for the analysis. The data is being released in advance of publication of the associated study in New Phytologist.

Data for Interfacial tension of graft block copolymers at immiscible homopolymer interfaces
(2025-04-29) Nehete, Ashutosh K; Bates, Frank S; Dorfman, Kevin D; dorfman@umn.edu; Dorfman, Kevin D; University of Minnesota Dorfman Research Group; University of Minnesota Bates Research Group
Graft multiblock copolymers are emerging as effective compatibilizers for immiscible polymer blends, leveraging the large parameter space offered by their branched architecture to surpass traditional linear diblock copolymers in compatibilization potential. We report the results of coarse-grained molecular dynamics simulations of AB graft copolymers at a strongly segregated A/B interface, focusing on the impact of graft copolymer loading at the interface and the copolymer architecture on the resulting interfacial tension of the system, which is correlated to copolymer conformation. At relatively low copolymer loadings, distributing the total grafting beads into a greater number of grafts enhances the copolymer interfacial coverage, effectively minimizing unfavorable homopolymer-homopolymer contacts and reducing interfacial tension. At relatively high copolymer loadings, once the interface is saturated with copolymers, molecules with a high number of grafts exhibit a greater penetration perpendicular to the interface, characterized by bending of the backbone and increased deviation of backbone beads from the interfacial plane. Our results demonstrate the existence of an optimal junction density beyond which the copolymers aggregate at the interface, leading to a plateau in interfacial tension as junction density increases further.
Supporting data for Thermal Performance of Materials for Heat-Assisted Magnetic Recording
(2025-04-28) Xu, Xiaotian; Zhang, Chi; Guo, Silu; Seaton, Nicholas; Mkhoyan, K. Andre; Roth, Joseph; Gong, Jie; Zheng, Xuan; Zuckerman, Neil; Wang, Xiaojia; wang4940@umn.edu; Wang, Xiaojia; Materials Research Science & Engineering Center (MRSEC)
Heat-Assisted Magnetic Recording (HAMR) enhances hard disk storage capacity by using localized laser heating to transiently lower the coercivity of high thermal-stability media, enabling nanoscale bit writing. A critical barrier to HAMR implementation lies in thermal management, necessitating accurate determination of material thermal properties across operational temperatures. Here, we investigate the temperature-dependent thermal conductivities (300–500 K) of thin-film materials in HAMR heads—including dielectrics (amorphous SiO₂, Al₂O₃, AlN), metals (Au, Cu), and magnetic alloys (NiFe, CoFe)—using time-domain thermoreflectance. Amorphous SiO₂ and Al₂O₃ exhibit rising thermal conductivity with temperature, consistent with typical amorphous material behavior. In contrast, polycrystalline AlN displays weak thermal anisotropy, with both in-plane and cross-plane conductivities decreasing as temperature increases. These values are substantially lower than those of single-crystal bulk AlN, a consequence of phonon scattering at grain boundaries and defects. Metallic (Au, Cu) and magnetic alloy (NiFe, CoFe) films show negligible thermal conductivity variations across the tested temperature range. For Au and Cu, the suppressed thermal conductivities align with predictions from a diffuse electron-boundary scattering model. These findings establish essential structure-thermal property relationships for optimizing HAMR head materials, particularly highlighting the role of microstructural defects in suppressing heat transfer within dielectric layers while affirming the temperature resilience of metallic components.
VCF of insertions and deletions found at high levels in multi breed Equus caballus population
(2025-04-28) Marlowe, Jillian L; Durward-Akhurst, Sian A; McCue, Molly E; marlo072@umn.edu; Marlowe, Jillian; University of Minnesota Equine Genetics and Genomics Lab
Datasets containing high confidence single nucleotide polymorphisms that exist in the genome of horses have previously been published in support of population genetic studies, disease variant discovery, and other type of genetic research. There are no similar datasets for insertions and deletions (indels). Here we created a preliminary set of indels that exist within a certain range of allele frequencies in a large diverse population of apparently healthy horses. A total of ~2M indels passed GATK filtering thresholds and had an allele frequency between 1% and 60%. Though the criteria for inclusion in this dataset are lenient to increase the total numbers these loci are likely to exist in the equine genome and can be used as a preliminary set of indels for some genetic studies. So far this set of indels has been used to create simulated equine genomes that will be used as a benchmarking measure of variant calling and genotyping methods.
Ekembo adult dentition and mandible measurements
(2025-04-28) McNulty, Kieran P; Begun, David R; Kelley, Jay; kmcnulty@umn.edu; McNulty, Kieran; University of Minnesota Department of Ecology, Evolution, & Behavior
These data represent dental and mandibular dimensions collected over many years as part of a broader effort to address questions of taxonomic diversity and distribution among Eastern African fossil sites that date to the Early Miocene (ca. 23-16 Ma). They were collected from original fossil specimens by the Principal Investigator listed above, though at various times numbers were recorded by student assistants while the PI was measuring. All specimens in this dataset are considered to belong to, or be related to, the fossil ape genus Ekembo. All specimens except one were found by paleontological research teams working on Rusinga Island and Mfangano Island, in Homa Bay County, western Kenya; that exception is a single tooth (NHMUK-P-M 32309) found at the Chianda Uyoma locality in Siaya County. Most of the fossils are housed at the National Museums of Kenya, Nairobi, and hence their accession numbers typically have the prefix KNM-RU (Rusinga) or KNM-MW (Mfangano). A series of partial skeletons discovered at the Kaswanga Primate Site (KPS) on Rusinga Island has never been fully accessioned, and these specimens are identified by Roman numerals (I-X) indicating to which individual they belong; they are identified in this dataset using the prefix KNM-KPS followed by that Roman numeral identifier, but those are not formal accession numbers. Fossils housed at the Natural History Museum (London) have the prefix NHMUK-P-M regardless of the locality of origin. Specimens referred to Ekembo by the authors or by others may not be included in this dataset if, for example, they did not preserve the anatomy to take of any these measurements or they represent deciduous dentition. Other specimens were not included here if the authors deemed them better referred to other taxa.

This dataset contains genomic variant calls, structural variation data, and phenotypic measurements related to Hordeum vulgare (barley). It includes VCF and BED files from multiple sequencing platforms—10x Genomics, Oxford Nanopore, PacBio, and Illumina featuring raw, filtered, and phased variants. Structural variant calls in BEDPE format and callable/un-callable region lists are provided. Phenotype data from field trials provide spatially adjusted and raw trait values for agronomic characteristics. These data provide insight on genomic diversity, structural variation, and genotype-phenotype associations in barley. The use of multiple sequencing technologies enables cross-validation of variant calls, allowing for high-confidence genome annotation and population genetics studies. The filtered VCFs help isolate biologically relevant mutations, while the callable region data ensure rigorous quality control for variant interpretation. This dataset is being released as it is supporting the associated paper to this research and also to support the broader research community in comparative genomics, evolutionary biology, and crop improvement studies. By making these resources publicly available, we aim to enhance reproducibility, enable novel insights into barley’s genomic architecture, and assist breeding efforts focused on climate resilience and agronomic performance.
