title: Better STEP, a format and dataset for boundary representation

description: Boundary representation (B-rep) generated from computer-aided design (CAD) is widely used in industry, with several large datasets available. However, the data in these datasets is represented in STEP format, requiring a CAD kernel to read and process it. This dramatically limits their scope and usage in large learning pipelines, as it constrains the possibility of deploying them on computing clusters due to the high cost of per-node licenses. This dataset introduces an alternative format based on the open, cross-platform format HDF5 and a corresponding dataset for STEP files. To demonstrate the effectiveness of the format, we converted the Fusion 360 dataset and the ABC dataset. For more information visit https://better-step.github.io

title: Electron Diffraction Data and Ptychographic Reconstructions Using a 20 keV Electron Beam on Supported Gold Nanoparticles

description: The data set contains scanning transmission electron diffraction data and ptychographic reconstructions from experiments performed with a 20 keV electron beam on gold particles on thin amorphous carbon and few-layer MoS2 supports. The ptychographic reconstructions present sub-Ångström information, as determined from Fourier ring correlation. Intermediate stage outputs from the ptychographic algorithms are also provided, along with parameters for the reconstruction recipes in tabulated form. To supplement the experimental results, simulated diffraction data and their related reconstructions are provided. The simulated data use conditions similar to the experimental data, and are provided for a synthetic abstract single-slice test object and a multi-slice simulated hexagonal-frustum-shaped gold islands on 5-layer MoS2. The model of the gold island on MoS2 is tilted to approximately match the experimental conditions, though has no over- or under-lying amorphous material present, which is likely to be present in the experimental data as described in the publication related to this dataset. The code required to process the supplied data and produce the reconstructions is provided in a related git repository at https://github.com/ArthurBlackburn/PtychoRunner.

title: Experimental data supporting DNA aptamer recognition of bilirubin and biliverdin for biosensing applications

description: This dataset supports the discovery and characterization of two DNA aptamers, Bvd4 and Brb7, that selectively bind to the bile pigments biliverdin and bilirubin, respectively—metabolites derived from heme degradation. These pigments are clinically relevant biomarkers associated with conditions such as neonatal jaundice, liver dysfunction, and hemolysis. The aptamers identified in this study may also serve as molecular switches for regulating gene expression. To support rigorous validation and reuse, the dataset includes raw experimental data obtained from: - Fluorescence titration assays using Thioflavin T (ThT) for binding curve generation. - Isothermal titration calorimetry (ITC) for thermodynamic profiling and dissociation constant (Kd) measurement. - Nuclear magnetic resonance (NMR) spectroscopy for structural validation and analysis of aptamer–ligand interactions. - UV–Vis spectroscopy for assessing pigment stability and monitoring bilirubin oxidation, - Sensor kinetic assays for evaluating real-time detection response and selectivity, and limit-of-detection (LOD) determination, The tightest biliverdin aptamer exhibited a Kd of 6 nM and an LOD of 0.7 nM. A separate aptamer showed specific binding to bilirubin with a Kd of 203 nM and an LOD of 47 nM. These values were confirmed using multiple orthogonal techniques. All experiments were conducted under controlled laboratory conditions at 25°C. Data are organized in tidy CSV format and correspond to Figures 3–8 and S1–S3 of the main article. Each file contains numeric measurements such as emission intensities, integrated heats, chemical shift data, and spectral information. This dataset facilitates further research into aptamer–target interactions, biosensor development, and nucleic acid-based sensing strategies for heme metabolites.

title: Cross-Binding of Adenosine by Aptamers Selected Using Theophylline

description: We recently reported that some adenosine binding aptamers can also bind caffeine and theophylline with around 20-fold lower affinities. This discovery led to the current work to examine the cross-binding of adenosine to theophylline aptamers. For the DNA aptamer for theophylline, cross-binding to adenosine was observed, and the affinity was 18 to 38-fold lower for adenosine based on assays using isothermal titration calorimetry and ThT fluorescence spectroscopy. The binding complexes were characterized using NMR spectroscopy, and both adenosine and theophylline showed an overall similar binding structure to the DNA theophylline aptamer, although small differences were also observed. In contrast, the RNA aptamer did not show binding to adenosine, although both aptamers have very similar relative selectivity for various methylxanthines including caffeine. After a negative selection, a few new aptamers with completely different primary sequences for theophylline were obtained and they did not show binding to adenosine. Thus, there are many ways for aptamers to bind theophylline and some can have cross-binding to adenosine. In biology, theophylline, caffeine, and adenosine can bind to the same protein receptors to regulate sleep, and their binding to the same DNA motifs may suggest an early role of nucleic acids in similar regulatory functions.

title: Capture-SELEX of DNA Aptamers for Sulforhodamine B and Fluorescein

description: While many dye binding aptamers have been reported, most of them were for light-up aptamers that can significantly enhance the quantum yield of fluorophores. Sulforhodamine B (SRhB) was used as a target previously to select both DNA and RNA aptamers, and the DNA aptamer was a G-quadruplex that can bind to a number of rhodamine analogs. In addition, the previous selections were performed by immobilizing the target molecules. In this work, we used the library immobilization method to respectively select aptamers for SRhB and fluorescein. The SRhB aptamer has a non-G-quadruplex structure with a Kd of 1.0 µM measured from isothermal titration calorimetry. Upon titration of the aptamer, the fluorescence of SRhB increased 2.5-fold, and this aptamer does not require Mg2+ for binding. Rhodamine B has even tighter binding suggesting binding through the xanthene moiety of the dyes. No binding was detected for fluorescein. For the fluorescein selection, a dominant aptamer sequence with a Kd of 147 µM was obtained. This study provides two new aptamers for two important fluorophores that can be used to study aptamer-based separation, dye detection, and catalysis. Comparison of these aptamers also provides insights into the effect of functional groups on aptamer binding.

title: Dataset for Examining the Effects of Nutrient Pulses on Biogeochemical Cycling in Subarctic Peatlands in the Context of Permafrost Thaw and Wildfires

description: This dataset contains results from a laboratory soil incubation experiment for subarctic bog and fen shallow peat cores. The main goal of this one-month experiment was to examine the immediate biogeochemical responses of subarctic peat samples to sudden nutrient additions, nitrogen (N) and phosphorus (P) in dissolved bioavailable forms (i.e., ammonium, nitrate, and phosphate). The main data product was the set of greenhouse gas flux rates from the control and nutrient-added peat samples, including the measurements of carbon dioxide (CO2), methane (CH4), and nitrogen oxide (N2O), although the N2O results were not discussed in the associated manuscript "Examining the Effects of Nutrient Pulses on Biogeochemical Cycling in Subarctic Peatlands in the Context of Permafrost Thaw and Wildfires" (in submission, 2023) as the discussion focused on microbial carbon (C) cycling responses. Other analysis results relevant to the interpretation of C gas emission rates were included, such as porewater chemistry (i.e., concentrations of major cations and anions), peat organic matter composition (i.e., total C, N and P concentrations), and chloroform fumigation analysis (i.e., microbial biomass extraction and measurements of C, N and P concentrations).

title: Investigation of polyethylene terephthalate (PET) and polyamide (PA) microplastic degradation in situ in stormwater pond sediments

description: Microplastic accumulation in the environment, especially in bodies of water and sediment is a well known concern. Stormwater ponds act as microplastic sinks and draw pollutants from urban and industrial wastewater before it enters oceans or lakes. This results in high levels of microplastics remaining in stormwater pond sediment. The degradation potential of two vastly produced polymers, polyethylene terephthalate (PET) and polyamide (PA) in sediment was determined over the course of 14 months. Pore water chemistry data was collected concurrently with measuring plastic mass loss. High levels of pollutants, such as fluoride, chloride and sulphate were found. Both polymers increased in mass for the first 6 months, due to water absorption. At 14 months, PET had degraded 0.22% and PA had a net positive mass but had decreased water absorption. The obtained results highlight the lack of degradation of plastics in stormwater pond sediment and suggest lifespans are longer than estimated.

title: Data for: Assessing Red Blood Cell Deformability from Microscopy Images Using Deep Learning

description: Abstract: Red blood cell (RBC) deformability is a key biophysical property that enables their navigation through small spaces in the microvasculature. The loss of RBC deformability can be due to pathology, natural ageing, or storage, and can impede proper cell function. Established methods to assess RBC deformability require specialized equipment, long measurement time, and skilled personnel. To address this, we used a deep learning image classification approach to differentiate between softer and harder RBCs. Ground truth deformability assessment was conducted using a microfluidic ratchet sorting device. After microfluidic deformability sorting, cells were imaged in brightfield at 40X magnification. Our model predicted individual RBC deformability with 81 ± 11% accuracy averaged across ten donors. This produced RBC deformability assessments within 10.4 ± 6.8% of the value obtained using the microfluidic device. Measuring RBC deformability using imaging is desirable as it only requires a standard imaging microscope, expanding its accessibility to clinics or research groups where this evaluation would otherwise not be feasible. Technical Information: 40X brightfield microscopy images of red blood cells in a 96-well imaging plate. Full well image scans were conducted using a DS-Qi2 camera on a Nikon Ti-2E inverted microscope, capturing images of 2424 x 2424 pixels.

title: PHyDAP - Prairie Hydrology Design and Analysis Product

description: The PHyDAP datasets are outputs of CRHM virtual basin models forced by long-term climate data sets, for more than 4,000 basins on the Canadian Prairies. The intent is that the CRHM model outputs will be used for forcing small-scale hydraulic models in the region. By running the hydraulic models for long time periods, the effects of changes in local hydraulics, and/or climate change on return-period flows and/or flooded areas can be assessed. The basins used for the CRHM models are derived from HydroSHEDS (https://www.hydrosheds.org/) as described by Lehner and Grill (2013). The virtual basin models are based on the basin classification described in Wolfe et al. (2019). An example of the use of the virtual basin models is given by Spence et al. (2022). The use of long-term hydrological model outputs to force small-scale hydraulic models is demonstrated by Altraide (2020).

title: Increased thermal tolerance does not alter behavioural performance in zebrafish larvae following rapid warming

description: Zebrafish were reared at 3 developmental temperatures before being acutely ramped up to higher temperatures where behaviour, metabolism, and biochemistry assays were performed. We explored the hypothesis that altered temperature during the embryonic window could influence thermal performance in zebrafish. Zebrafish embryos were maintained at either 24, 28, or 32°C until 2 days post-fertilization, and then transferred to a common garden temperature of 28°C until 5 days post-fertilization. Elevations in embryonic temperature led to an expected precocious development. At 5 days post-fertilization, we recorded the critical thermal maximum (CTMAX) as a measure of thermal tolerance. Fish reared at 32°C could withstand higher temperatures than fish reared at both colder temperatures. To test whether the embryonic temperature influenced larval performance, we acutely raised the temperature of larvae and measured oxygen consumption and behaviour at temperatures below their CTMAX (28-40°C) at a rate of 0.3°C/min. Fish reared in colder temperatures had higher oxygen consumption when temperatures were acutely raised. Exploratory behaviour was highest in fish acutely raised to 32-34°C, decreasing beyond 34°C, with colder rearing lowering movement. Responses to light and acoustic stimuli were maximal at 32°C. Together, temperature during the embryonic window influenced the absolute thermal tolerance of larvae but had more nuanced impacts on acute thermal performance.

title: Mesoscale imaging dataset of mouse brains using LabeoTech's imaging system and the Universal Mesoscale Imaging Toolbox (umIT).

description: This dataset contains mesoscale imaging data from mice captured using LabeoTech's imaging system. Spontaneous and evoked, resting-state calcium activity of mice was recorded before (baseline) and after (post-days) inducing an ischemic stroke in the area between the primary mortor cortex and somatosensory cortex using photothrombosis. Each imaging session involved recording spontaneous baseline activity, and for a subset of mice also involved three minutes of evoked activity while delivering whiskers stimulations. Raw mesoscale imaging data was analysed using the Universal Mesoscale Imaging Toolbox (umIT) (https://github.com/LabeoTech/Umit). Images were imported from the microscope binary files provided in this dataset and separated into red, green, amber, and fluorescent channels for analysis. Fluorescent images were hemodynamically corrected using the red, green, and amber channels to remove information about blood flow from the neuronal signal. Images were then aligned to the Mouse Allan Brain Atlas, and then aligned again using a reference image to reduce movement artefacts within and between recordings.
