<p>This is a processed data (Seurat object) that contain single cell RNA-seq data from mouse , E10.5, Sox17∆50/∆50 mutant and Sox17+/+ embryos enriched for EPCAM+/CXCR4+ endodermal cells. Dataset contains 2912 total cells post qc. Sox17+/+ and Sox17Δ50/Δ50 cell samples are labelled with barcodes from 3'CellPlex Kit (10X Genomics). CellPlex Barcode ID CMO307 represent Sox17+/+ and CMO309 represent Sox17Δ50/Δ50 cells (included in assay named "CMO"). Genotype labels are under metadata column "genotype" as well. Libraries were constructed according to the manufacturer’s instructions for 10x Genomics Single Cell 3′ Library kit v3.

Experimental and numerical investigation of the surface-modified treatment and aerodynamic performance of a ducted-fan impeller
<p>A ducted fan is a potential solution to improve the dynamic performance of an Unmanned Aerial Vehicle (UAV). The impeller of the ducted fan is the most critical plastic part. Compared with the injection molding process, the Fused Deposition Modeling (FDM) process has a lower cost and shorter cycle time, but its roughness and lift performance are undesirable. Based on the hydrophobic surface treatment and the related performance research of the ducted fan impeller, this research aimed to improve the anti-impedance properties. Then, the modified surface of the impeller was built based on mussel-inspired mechanisms and the chemical surface-coating process of fan products. Experiments were conducted using a scanning electron microscope with an ener-gy-dispersive x-ray spectroscopy system (SEM-EDS), laser scanning confocal microscopy (LSCM), and a UAV dynamic test platform. The experimental results show that the coating resulted in reduced surface roughness for injection molding and FDM molding, and the maximum lift of the impellers manufactured by the injection molding and FDM methods was increased by 3.3% and 12%, respectively. Moreover, the effect on the integrity of this coating process on FDM was significantly better than on the injection molding. The numerical analysis of the aerodynamic performance of the impeller with different roughness reveals the mechanism by which the surface treatment affects the blade effectiveness. The CFD results show that reducing the roughness led to less low-energy fluid in the flow channel and reduced the turbulent pulsation dissipation. In addition, the reduction in the blade's surface roughness decreased the boundary layer thickness and the boundary layer velocity. Thus, the aerodynamic performance of the impeller was optimized.</p>

Hydroacoustic and hydrodynamic investigation of bio-inspired leading-edge tubercles on marine ducted thrusters
<p>Underwater radiated noise (URN) has a negative impact on the marine acoustic environment where it can disrupt marine creature's basic living functions such as navigation and communication. To control the ambient ocean noise levels due to human activities, international governing bodies such as the International Maritime Organisation (IMO) have issued non-mandatory guidelines to address this issue. Under such framework, the hydroacoustic performance of marine vehicles has become a critical factor to be evaluated and controlled throughout the vehicles' service life in order to mitigate the URN level and the role humankind plays in the ocean. This study aims to apply leading-edge (LE) tubercles of the Humpback whales' pectoral fins to a benchmark ducted propeller to investigate its potential in noise mitigation. This was conducted using CFD, where the high-fidelity Improved Delayed Detached Eddy Simulations (IDDES) in combination with the porous Ffowcs-Williams Hawkings (FW-H) acoustic analogy was used to solve the hydrodynamic flow-field and propagate the generated noise to the far-field. It has been found that the LE tubercles have shown promising noise mitigation capabilities in the far-field, where the OASPL at J = 0.1 was reduced to a maximum of 3.4dB with a maximum of 11dB reduction in certain frequency ranges at other operating conditions. Based on detailed flow analysis researching the fundamental vortex dynamics, this noise reduction is shown to be due to the disruption of the coherent turbulent wake structure in the propeller slipstream causing the acceleration in the dissipation of turbulence and vorticity induced noise.</p>
