Topological perception on attention to product shape

A primitive and general function of the visual system is the perception of global topological properties. In fact, people prioritize attention to these properties over the local geometric properties of an object. In this study, we aimed to verify whether the perception of topological properties is applicable to product recognition. If a topological transformation occurs in the shape of a product, the product may receive more attention from customers and improved publicizing of the product’s innovative and nonvisual characteristics, such as function and experience, can be inferred. Therefore, topological properties may contribute to product innovation. We hypothesized that perceiving topological properties (e.g. holes, connectivity, and inside/outside relationships) occurs in product shapes, and human attention to products varies according to topological transformations in these shapes. Experimental results on bicycle recognition suggest that human attention varies according to topological transformations. A repertory grid was used to discover and discriminate the reasons for such variations. We extracted the mental constructs of the participants regarding the products with different topological transformations and identified the main reasons for visual attention. People pay more visual attention to the shapes of products with clear topological variations.</p

Image_2_Case Report: Mature Plasmacytoid Dendritic Cell Proliferation Associated With a Lymphoid Neoplasm.tiff

Mature plasmacytoid dendritic cell proliferations (MPDCPs) are clonal, non-malignant pDC proliferations that have been reported to occur in association with myeloid neoplasms such as CMML, AML (pDC-AML), and, rarely, MDS or MPNs. Here we report the first case of a MPDCP associated with T-lymphoblastic leukemia (T-ALL), a lymphoid neoplasm. The MPDCP in this case involved ~50% of the bone marrow, was found in nodular aggregates, expressed CD123, CD4, and CD303, and lacked CD56 and TCL1 expression. In addition, the MPDCP lacked CD34 and TdT but showed aberrant expression of CD7, CD5, CD10, and CD13, markers expressed by the abnormal T-lymphoblastic cells. Mutational analysis demonstrated mutations in JAK3, NOTCH1, NRAS, KRAS, DNMT3A, and SH2B3 but no mutations in TET2, ASLX1 or ZRSR2. Analysis of the pDC frequency in a separate cohort of T-ALL and control patients demonstrated that bone marrow pDCs are often decreased in patients with T-ALL compared to controls. This is the first report of a MPDCP associated with a lymphoid neoplasm and provides further support that MPDCP can arise from a multipotent hematopoietic progenitor with lymphoid and dendritic cell potential.</p

Introduction: Polysaccharides from Grifola frondosa (Dicks.) Gray (HSH) and Inonotus obliquus (Fr.) Pilat (BHR) showed noticeable effects on dextran sulfate sodium (DSS)-induced colitis, but their systemic modulation effects have not been fully revealed. This study aimed to investigate the regulation of the gut microbiota and systemic metabolism by HSH and BHR in DSS-induced colitis.Methods: C57BL/6J mice were given DSS (2.5%) in water and were treated with HSH and BHR (200 mg/kg/day) by gavage. Body weight and colon length were recorded, and H&E and AB-PAS staining of the colon were conducted to evaluate the model and the protective effect of the polysaccharides. Additionally, an LC-QTOF/MS-based untargeted metabolomic platform was used to identify the metabolites in the serum, colon tissue, gut contents, and faeces and investigate differential metabolites and metabolic pathways. 16S rDNA gene sequencing was used to measure the composition of bacterial communities.Results: The results showed that the mouse colitis model was established successfully, as evidenced by an increased disease activity index score [2.83 ± 0.62 vs. 0.06 ± 0.14 (p Discussion: These results suggested that HSH and BHR may ameliorate DSS-induced colitis by global modulation of systemic metabolism and the gut microbiota. Targeting the gut microbiota may be a potentially effective strategy to modulate systemic metabolism and treat colitis.</p

Vacuum Quenching for Large-Area Perovskite Film Deposition

The removal of precursor solvents in perovskite wet films plays a vital role in controlling the quality of perovskite films and devices. The dripping antisolvent method (removing precursor solvents) has made great advances in small-area devices, but this method limits the preparation of large-area perovskite films. Vacuum quenching that evaporates solvents by dropping the pressure is a potential large-area manufacturing approach. Herein, we have conducted a systematic comparative study on these two methods of depositing perovskite films. It is found that vacuum quenching can obtain the same film quality and small-area device efficiency (∼22.5%) as the antisolvent method. However, on a large-area substrate, the fast vacuum quenching rate improves the solvent evaporation efficiency and nucleation density (i.e., forming a large number of crystal nuclei), thereby obtaining a more uniform and stable perovskite film. Notably, the manufacture window exceeds 10 min. As a result, the champion large-area (6 × 6 cm2) perovskite solar module exhibits an impressive efficiency (17.86%) and long-term operational stability. Furthermore, coupling slot-die coating, vacuum quenching can realize the industrial continuous deposition of large-area perovskite films, which is a potential route for large-scale production
