SAN PEDRO MARTIR OPTICAL IMAGING OF 9P/TEMPEL 1 V1.0
The presented dataset represents 4 half-nights of observing at San Pedro Martir, Baja, Mexico. The target, Comet 9P/Tempel 1, was impacted by the Deep Impact impactor on the third night of observing, 4 July UT. The observations are optical broadband imaging (BVRI filters), on a 1.5 m telescope, with a time resolution around 10 sec near impact and 20 sec at most other times.
MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from Optical Images V003
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of mean monthly velocity maps for selected glacier outlet areas. The maps are generated by tracking visible features between optical image pairs acquired by the Landsat 4 and 5 Thematic Mapper (TM), the Landsat 7 Enhanced Thematic Mapper Plus (ETM+), the Landsat 8 Operational Land Imager (OLI), and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). See <a href="http://nsidc.org/data/measures/gimp">Greenland Ice Mapping Project (GIMP)</a> for related data.
MEaSUREs Greenland Ice Velocity: Selected Glacier Site Single-Pair Velocity Maps from Optical Images V001
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of surface velocity estimates for selected Greenland Ice Sheet outlet glaciers. Velocity fields were generated by tracking visible features in optical images acquired by the U.S. Geological Survey (USGS) Landsat 8 Operational Land Imager (OLI) and the European Space Agency (ESA) Copernicus Sentinel-2A and Sentinel-2B satellites.

Optical imaging and single-cell RNA sequencing reveal individual heterogeneity in pancreatic cells that supports global function
<p>Islets, micro-organs critical for glucose homeostasis, exhibit significant genetic diversity among their cells, which is hypothesized to underpin their functional repertoire. Our study investigated the heterogeneity in glucose-induced excitability within islet cells, providing a cellular basis for their roles in glucose-responsive hormone secretion. To comprehensively map glucose-induced excitability profiles, we developed SHIMMER, a high-throughput, multimodal data acquisition platform that integrates electrical signals, Ca2+ fluxes, and single-cell sequencing data. By quantifying the non-stationary electrical and calcium signal dynamics, we formulated a machine learning-based electro-calcium model that shows how variations in membrane conductance and Ca2+ clearance contribute to increased heterogeneity in cytosolic Ca2+ accumulation. Using SHIMMER for single-cell sequencing on representative cells, we identified genes such as <em>Cacnb2</em> and <em>Arpp19</em>, that associated with electro-calcium characteristics, and found <em>Clec4d</em> as a potential marker for a highly excitable cell subpopulation. These findings indicate that islet cells tend to exhibit a large heterogeneity in glucose-induced excitability, being essential for their normal functioning.</p>

Using SHIMMER for single-cell sequencing on representative cells, we identified several genes that associated with electro-calcium characteristics, and found a potential marker for a highly excitable cell subpopulation. These findings indicate that islet cells tend to exhibit a large heterogeneity in glucose-induced excitability, being essential for their normal functioning.</p> <p>This dataset include all processed data we mentioned in our paper, the code were uploaded on https://github.com/CullinanLi/heterogeneity-in-pancreatic-islet-cells, with the same folder name, if we missed anything, please feel free to contact the lead contact.</p>

Analysis of an optical imaging system prototype for autonomously monitoring zooplankton in an aquaculture facility
<p>This upload consists of a zip file containing all the images used in the zooplankton training library. Individual folders of each zooplankton class contain all the images in the training library for that respective class. Each image is labeled with its actual classification. The labeled images provide a reproducible source to test and retest various classification algorithms and image decomposition approaches.</p>
