Discrete Flow Cytometry of Underway Samples from TN398 Using a BD Influx Cell Sorter
<p>The dataset consists of BD Influx-based analysis of picophytoplankton populations from discrete flow cytometry data collected underway during the University of Washington School of Oceanography undergraduate senior thesis cruise (TN398) during December 2021 from Honolulu to San Diego, crossing through the Great Pacific Garbage Patch. The data includes cell abundance, cell size (equivalent spherical diameter), carbon quota, and carbon biomass for picophytoplankton populations, namely the cyanobacteria Prochlorococcus, Synechococcus, and and small eukaryotic phytoplankton (<5 μm ESD). Time is in UTC format, latitude and longitude are in decimal degrees, and depth is in meters. Further information can be found here: https://github.com/fribalet/FCSplankton</p>
Data from: Treated like dirt: Robust forensic and ecological inferences from soil eDNA after challenging sample storage
<p>We investigated the effect of storage duration and conditions on the assessment of the soil biota with eDNA metabarcoding. We extracted eDNA from freshly collected soil samples and again from the same samples after storage under contrasting temperature conditions and contrasting exposure (open/closed tubes). We used four different primer sets targeting bacteria, fungi, protists (cercozoans), and general eukaryotes. <span>W</span>e quantified differences in richness, evenness, and community composition. Subsequently, we tested whether we could correctly infer habitat type and original sample identity after storage using a large reference dataset.</p> <p>This repository contains the un-demultiplexed fastq sequences.</p>

Figure 4: Spectro°uorimetric spectra of TiO2/CdS composites samples with a di®erent mass proportion-PREPARATION AND CHARACTERIZATION OF TIO2/CDS LAYERS AS POTENTIAL PHOTOELECTROCATALYTIC MATERIALS
<p>Fig. 4 illustrates the fluorescence emission spectra of TiO2/CdS nanostructured ¯lm at the exciting<br> wavelength of 340 nm. The curves for TC 1, TC 2, TC 3 and TC 4 exhibited<br> the clear photoemission peaks at about 375 nm, and compared with emission of<br> bulk CdS (520 nm), 145 nm of blue shift was observed. These features indicate<br> the quantum-con¯ned e®ect of the TiO2/CdS nanocomposite ¯lms [25].</p>

<p>To increase the autonomy of deaf and hard of hearing people in their day-to-day<br> professional and social lives, in this paper design and initial implementation of a new approach<br> based on MFCC and Vector Quantization Method is described. This approach includes<br> analyses of speech to animate the talking head. Our future work will include the conception of<br> new test types and performance patterns. We are particularly interested in extending this<br> approach to testing to include implementation of applications under real-time constraints</p>

<p>This upload provides additional information and data related to the paper "<span>Assessing First Time Usability of a Hand Augmentation Device in a Large Sample of Diverse Users</span>" (Clode et al., 2024).</p> <p>The study investigated users' first-time usage of the Third Thumb at "The Royal Society Summer Science Exhibition 2022", a large public engagement event held from July 6th to July 10th, 2022, at The Royal Society in London, England. The exhibition attracted more than 6,000 visitors.</p> <p>The Third Thumb is a supernumerary robotic finger. During the event, nearly 600 participants practiced using the Third Thumb in motor tasks aimed at different aspects of motor control. We examined how various demographic factors affected performance.</p>
