A Pyramid Attention Network(PAN) is proposed to exploit the impact of global contextual information in semantic segmentation. Different from most existing works, we combine attention mechanism and spatial pyramid extract precise dense features for pixel labeling instead complicated dilated convolution artificially designed decoder networks. Specifically, introduce a Feature module perform structure on high-level output combining pooling learn better feature representation, Global Upsample...
In this paper, we reported the in situ fabrication of highly luminescent formamidinium lead bromide (FAPbBr3) nanocrystal thin films by dropping toluene as an anti-solvent during spin-coating with a perovskite precursor solution using 3,3-diphenylpropylamine (DPPA-Br) ligand. The resulting are uniform and composed 5-20 nm FAPbBr3 nanocrystals. By monitoring solvent mixing on substrates, illustrated difference between ligand-assisted reprecipitation (LARP) process nanocrystal-pinning (NCP)...
Abstract The quantum dot spectrometer, fabricated by integrating different dots with an image sensor to reconstruct the target spectrum from spectral-coupled measurements, is emerging and promising hyperspectrometry technology high resolution a compact size. spectral range of spectrometers have been limited variety available robustness algorithmic reconstruction. Moreover, spectrometer integration also suffers inherent photoluminescence emission poor batch-to-batch repeatability. In this...
Estrogen receptors ERα and ERβ share considerable sequence homology yet exert opposite effects on breast cancer cell proliferation. While the proliferative role of in tumors is well characterized, it not clear whether antitumor activity can be mobilized cells. Here, we have shown that phosphorylation a tyrosine residue (Y36) present ERβ, but ERα, dictates ERβ-specific activation transcription required for ERβ-dependent inhibition growth culture murine xenografts. Additionally, c-ABL kinase...
Abstract In this work, the integration of in situ fabricated perovskite quantum dots embedded composite films (PQDCFs) as downshifting materials is first reported for enhancing ultraviolet (UV) response silicon (Si) photodetectors toward broadband and solar‐blind light detection. External efficiency measurements show that UV PQDCF coated Si photodiodes greatly improves from near 0% to at most 50.6% ± 0.5% @ 290 nm. As compared calculated maximum value 87%, coupling integrated device...
Abstract Luminescence downshifting (LDS) layer integration has been proven to be an efficient way ameliorate the poor UV-blue spectral response and improve power conversion efficiency (PCE) for solar cells (SCs). By employing in situ fabricated CH 3 NH PbBr (CH = methylammonium, MAPbBr ) quantum dot/polyacrylonitrile (PAN) composite film as LDS layer, we observed a clear enhancement external (EQE) silicon SCs, predominantly region. With theoretically calculated intrinsic ( η of up 72%, SCs...
Perovskite quantum dots (PQDs) are emerging as functional luminescence down-shifting materials for light conversion applications. The incorporation of PQDs into a polymeric matrix is key step to improving their stability, thus facilitating device integration. Compared the conventional way mixing pre-synthesized polymer, in situ fabrication perovskite dots-embedded composite films (PQDCFs) an efficient and cost-effective method, which yields enhanced photoluminescence properties. This method...
Abstract Polarization can be used to distinguish artificial objects in complicated environments. The development of polarization‐sensitive detection at ultraviolet (UV) wavelengths has been substantially delayed by the difficulties fabricating anisotropic materials and optical elements for polarization modulation. Polarization‐sensitive UV is developed combining an electron‐multiplying charge‐coupled device (EMCCD) with a polarized luminescence downshifting material that benefits from...
This study investigates a 2D gas–solid fast fluidized bed of typical Geldart A particles using highly resolved simulations with two-fluid model. The results show that the solid shear rate has considerable impact on orientation meso-scale structures and hence filtered drag force. On basis correlation for force established in literature traditional markers (such as volume fraction, slip velocity filter scale), correction correlated direction gravity is proposed better prediction corrected...
A real-time color transfer system based on 3 pieces of multi-media DSP TM1300 for low-light level visible(LLLV) and infrared(IR) images is built. Computing quantity split among three TM13003. Two preprocess the dual-band calculate their mean standard deviation respectively. The third executes fusion in YUV space: Firstly two preprocessed are fused into one primary image(source image) which hot targets present warm color, cold cool color. Then source Y, U, V components deduced by pixel value...
