Video1_Correlation of the position and status of the polar body from the fertilized oocyte to the euploid status of blastocysts.MP4
Polar bodies are tiny cells that are extruded during oocyte meiosis and are generally considered not essential for embryonic development. Therefore, polar bodies have been widely used as important materials for the preimplantation genetic diagnosis of human embryos. Recent studies have shown that polar bodies mediate embryonic development and that their morphology is related to embryo quality and developmental potential. However, the relationship between the emission of the polar body and embryonic euploidy remains unclear. In this study, a total of 1,360 blastocyst trophectoderm (TE) biopsies were performed, and blastocyst ploidy results were correlated with the state of polar bodies. The results showed that polar body angle size and polar body status are not directly related to whether the blastocysts are euploid, aneuploid, or mosaic (p > 0.05). Therefore, in the process of clinical embryo selection, embryologists should not predict the euploidy of blastocysts based on the state of polar bodies, thus affecting embryo selection.</p
The spatial extent of datasets integrated into Swept Area Seabed Impact (SASI) model grid.
<p>The University of Massachusetts Dartmouth School of Marine Science and Technology (SMAST) broadscale drop camera survey was conducted from 2003–2012 on a 5.6 km grid, with finer scale surveys on 1 to 4 km grids in certain years, to monitor sea scallop populations. The Northeast Coastal Ocean Forecast System (NECOFS) was used to hindcast oceanographic conditions.</p
Areas and frequency of consistent benthic animal concentrations and bottom temperature anomalies.
<p>The bottom panel displays bottom temperature anomalies only for areas with persistent benthic assemblages. Outlined areas are closed to mobile, bottom fishing gear except for the hatched areas, which are periodically opened to sea scallop fishing.</p
Visualization of benthic animal dataset created from integration of The University of Massachusetts Dartmouth School of Marine Science and Technology drop camera survey data into the Swept Area Seabed Impact model grid.
<p>The dataset includes abundance information for eight animal groups (sea stars, sea scallops, hermit crabs, skates, red hake, moon snails, crabs, and flatfishes) as well as presence/absence data for four additional groups (bryozoa/hydrozoa, sand dollars, sponges, and burrowing species) on an annual and decadal scale. In addition, each uniquely identified cell contains information on the number, average depth, and variation between the survey stations used to create the data within the cell.</p
Areas of bottom temperature anomalies.
<p>An anomaly was present when an annual temperature value was one standard deviation higher (red) or lower (blue) than the average variation from 2003–2012. Only years from 2003–2012 with temperature variations outside of this range are displayed.</p
Visualization of environmental dataset created from integration of The Northeast Coastal Ocean Forecast System data into the Swept Area Seabed Impact model grid.
<p>The dataset includes information for six environmental variables (surface and bottom temperature and salinity, and maximum and average bottom stress) on monthly, annual and decadal scales. In addition, each uniquely identified cell contains information on the number and variation between the model output locations used to create the data within the cell.</p

Minimum bias measurement at 13 TeV
The modelling of Minimum Bias (MB) is a crucial ingredient to learn about the description of soft QCD processes and to simulate the environment at the LHC with many concurrent pp interactions (pile-up). We summarise the ATLAS minimum bias measurements with proton-proton collision at 13 TeV center-of-mass-energy at the Large Hadron Collider

Characteristic Plasmon Energies for 2D In<sub>2</sub>Se<sub>3</sub> Phase Identification at Nanoscale
Two-dimensional
(2D) materials with competing polymorphs offer
remarkable potential to switch the associated 2D functionalities for
novel device applications. Probing their phase transition and competition
mechanisms requires nanoscale characterization techniques that can
sensitively detect the nucleation of secondary phases down to single-layer
thickness. Here we demonstrate nanoscale phase identification on 2D
In2Se3 polymorphs, utilizing their distinct
plasmon energies that can be distinguished by electron energy-loss
spectroscopy (EELS). The characteristic plasmon energies of In2Se3 polymorphs have been validated by first-principles
calculations, and also been successfully applied to reveal phase transitions
using in situ EELS. Correlating with in situ X-ray diffraction, we
further derive a subtle difference in the valence electron density
of In2Se3 polymorphs, consistent with their
disparate electronic properties. The nanometer resolution and independence
of orientation make plasmon-energy mapping a versatile technique for
nanoscale phase identification on 2D materials
