Abstract

ObjectiveTo comprehend the epidemiological and molecular characteristics of diarrheagenic Escherichia coli （DEC） in a specific district of Beijing City from 2018 to 2022， aiming to provide evidence for the prevention and control of related diseases.MethodsStool specimens of 1 600 diarrhea cases were collected from 3 surveillance sentinel hospitals in one district of Beijing from 2018 to 2022， and DEC strains were isolated from the specimens. The virulence genes were detected by multiplex PCR， and the pathogenic types were obtained. The epidemiological and clinical data were analyzed. Simultaneously， pulsed-field gel electrophoresis （PFGE） was used to ascertain the molecular types of the strains. Cluster analysis was performed on the fingerprints of ETEC， EPEC， and EAEC strains.ResultsDEC strains were isolated in 144 of 1 600 specimens from one district of Beijing from 2018 to 2022， with a detection rate of 9.00% （144/1 600）. The primary pathogenic type was ETEC， followed by EPEC， EAEC， and EHEC， no EIEC cases were detected. The male-to-female ratio of DEC infection cases was 1.48∶1， with the highest detection rate occurring in the 31~45 age group （11.15%， 59/529）. The year 2019 exhibited the highest positive detection rate of DEC， with the highest rates consistently observed during the summer months. Significant differences in the positive detection rate of DEC were observed among different age groups and years. Most of the DEC-positive patients suffered diarrhea， dehydration， abdominal pain and watery stool. The 144 DEC strains yielded 111 bands， with homology ranging from 13.07% to 100.00%. Isolates of the same type ranged from 2 to 7 strains， and their separation intervals varied from the same day to several years.ConclusionETEC and EPEC were the predominant pathogenic types of DEC in this area， while EHEC infections persisted. DEC exhibited a high incidence during the summer and was more frequently detected in young adults. The PFGE bands exhibited a highly polymorphic distribution.

Abstract

Ti/(TiB+TiC) titanium matrix composites with the excellent mechanical properties were prepared by vacuum pressureless sintering and hot extrusion by using low-cost TiH2 powders instead of pure titanium powders and adding B4C to in-situ produce TiB and TiC reinforcements. The effects of preparation technology and reinforcements on the microstructure and properties of the Ti/(TiB+TiC) composites were analyzed. The results show that the TiH2 powders have the good sintering activity, and the relative density of the sample after dehydrogenation and sintering can reach 97.7%, which is further increased to 99.9% after the hot extrusion as closed to full density. The TiB reinforcements are short fibrous, and the TiC reinforcements are granular, which are uniformly distributed in the equiaxed α-Ti matrix, restraining the growth of equiaxed grains and refining the grains. The hot extrusion process can further refine the grains and make the microstructure more uniform and compact, the as-extruded titanium matrix composites show the high hardness and good matching of strength and ductility. The TiH2+4%B4C (volume fraction) extruded composites have the Vickers hardness of Hv0.3 310, yield strength of 683 MPa, tensile strength of 851 MPa, and elongation of 15.1% after fracture.

Abstract

Understanding interior scenes has attracted enormous interest in computer vision community. However, few works focus on the understanding of furniture within the scenes and a large-scale dataset is also lacked to advance the field. In this paper, we first fill the gap by presenting DeepFurniture, a richly annotated large indoor scene dataset, including 24k indoor images, 170k furniture instances and 20k unique furniture identities. On the dataset, we introduce a new benchmark, named furniture set retrieval. Given an indoor photo as input, the task requires to detect all the furniture instances and search a matched set of furniture identities. To address this challenging task, we propose a feature and context embedding based framework. It contains 3 major contributions: (1) An improved Mask-RCNN model with an additional mask-based classifier is introduced for better utilizing the mask information to relieve the occlusion problems in furniture detection context. (2) A multi-task style Siamese network is proposed to train the feature embedding model for retrieval, which is composed of a classification subnet supervised by self-clustered pseudo attributes and a verification subnet to estimate whether the input pair is matched. (3) In order to model the relationship of the furniture entities in an interior design, a context embedding model is employed to re-rank the retrieval results. Extensive experiments demonstrate the effectiveness of each module and the overall system., Comment: project website : https://www.kujiale.com/festatic/furnitureSetRetrieval
