Middle and outer ear diseases are common otological diseases worldwide.Otoscopy and otoendoscopy exami-nations are essential first steps in the evaluation of patients with otological diseases.Misdiagnosis often occurs when the doctor lacks experience in interpreting the results of otoscopy or otoendoscopy,leading to delays in treatment or complications.Using deep learning to process otoscopy images and developing otoscopic artificial-intelligence-based decision-making systems will become a significant trend in the future.However,the uneven quality of otoscopy images is among the major obstacles to development of such artificial intelligence systems,and no standardized process for data acquisition,and annotation of otoscopy images in intelligent medicine has yet been fully established.The standards for data storage and data management are unified with those of other specialties and are introduced in detail here.This expert recommendation criterion improved and standardized the collection and annotation procedures for otoscopy images and fills the current gap in otologic intelligent medicine;it would thus lay a solid foundation for the standardized collection,storage,and annotation of oto-scopy images and the application of training algorithms,and promote the development of automatic diagnosis and treatment for otological diseases.The full text introduced image collection(including patient preparation,equipment standards,and image storage),image annotation standards,and quality control.

An Energy-Efficient Data collection Scheme Using Denoising Autoencoder in Wireless Sensor Networks

引用

Tsinghua Science and Technology 2019年第1期24卷 86-96页

作者： Guorui Li Sancheng Peng Cong Wang Jianwei Niu Ying Yuan School of Computer Science and Engineering Northeastern University School of Information Science and Technology Guangdong University of Foreign Studies State Key Laboratory of Virtual Reality Technology and Systems Beihang University

As one of the key operations in Wireless Sensor Networks(WSNs), the energy-efficient data collection schemes have been actively explored in the literature. However, the transform basis for sparsifing the sensed data is usually chosen empirically, and the transformed results are not always the sparsest. In this paper, we propose a Data collection scheme based on Denoising Autoencoder(DCDA) to solve the above problem. In the data training phase, a Denoising AutoEncoder(DAE) is trained to compute the data measurement matrix and the data reconstruction matrix using the historical sensed data. Then, in the data collection phase, the sensed data of whole network are collected along a data collection tree. The data measurement matrix is utilized to compress the sensed data in each sensor node, and the data reconstruction matrix is utilized to reconstruct the original data in the sink.Finally, the data communication performance and data reconstruction performance of the proposed scheme are evaluated and compared with those of existing schemes using real-world sensed data. The experimental results show that compared to its counterparts, the proposed scheme results in a higher data compression rate, lower energy consumption, more accurate data reconstruction, and faster data reconstruction speed.

A novel gradient climbing control for seeking the best communication point for data collection from a seabed platform using a single unmanned surface vehicle

引用

Frontiers of Information Technology & Electronic Engineering 2019年第6期20卷 751-759页

作者： Jiu-cai JIN Jie ZHANG Zhi-chao LV First Institute of Oceanography Ministry of Natural Resources Qingdao 266061 China College of Underwater Acoustic Engineering Harbin Engineering University Harbin 150001 China

A novel controller for finding the best communication point is proposed for collecting data from a seabed platform by a single unmanned surface vehicle(USV) using underwater acoustic communication(UAC). As far as we know, extremum seeking based on climbing control is usually implemented by multiple vehicles or agents because of the large range of measurement and easy acquisition of gradient estimation. A single vehicle cannot rapidly estimate the field because of the limited extent for measurement;therefore, it is difficult for a single vehicle to seek the extremum point in a field. In this study, an oscillation motion(OM) is designed for a single USV to acquire UAC’s link strength data between the seabed platform and the USV. The field for UAC’s link strength is updated using new measurement from an OM of the USV based on a multi-variable weight linear iteration method. A controller for seeking the best UAC’s point of the USV is designed using gradient climbing and artificial potential considering iterative estimation of an unknown field and an OM operation, and the stability is proved. The reliability and efficiency are shown in simulation results.

New design for multi-crystal data collection at SSRF

Data collection with microcrystals at synchrotron radiation facilities is challenging because it is difficult to harvest and locate microcrystals. Moreover,microcrystals are sensitive to radiation damage; thus, typically, a complete data set cannot be obtained with a single microcrystal. Herein, we report a new method for data collection with multiple microcrystals having a crystal size ranging from 1 to 30 lm. This method is suitable for not only low-temperature(100 K) data collection but also room-temperature data collection. Thin Kapton membranes were used to capture multiple crystals simultaneously. The microcrystals were visible under an optical microscope and easily located because the membrane was transparent and sufficiently thin. The film was fixed to a bracket that was prepared using a three-dimensional printer. The bracket was fixed on a magnetic base via screwing and employed by the goniometer system for data collection. Multiple data sets of fatty acid-binding protein 4(FABP4) and lysozyme microcrystals were collected using this novel designed device. Finally, the structures of protein FABP4 and lysozyme were obtained from these data via the molecule replacement method. The data statistics reveal that this method provides a comparable result to traditional methods such as a nylon loop.

Numerical study of collection efficiency and heat-transfer characteristics of packed granular filter

引用

Particuology 2019年第5期17卷 75-82页

作者： Junlin Chen Xunfeng Li Xiulan Huai Yongwei Wang Jingzhi Zhou Institute of Engineering Thermophysics Chinese Academy of Sciences Beijing 100190 China University of Chinese Academy of Sciences Beijing 100049 China

The collection mechanism and heat-transfer characteristics of a packed granular filter were investigated using a three-dimensional randomly packed granular filter model. The bridging method was introduced to optimize the grids of contact points between granules. The influences of granular bed depth, gas velocity, and gas temperature on grade collection efficiency were investigated. The results indicated that a decrease of temperature improved collection efficiency when the particle diameter was greater than 5 |xm. The grade collection efficiency maintained a stable value when the Stokes number, St, was less than 0.009, but increased linearly with ig(St) when St > 0.009. A logarithmic mean temperature difference method was used to obtain overall heat-transfer coefficients of gas-solid two-phase flow through the packed granular filter. The results showed that convective heat transfer was enhanced due to the intro-duction of solid particles in the bed. The overall heat-transfer coefficient increased approximately linearly with an increase in particle loading ratio. The Nusselt number was related to the Reynolds number, the Archimedes number, and the particle loading ratio.

The curd of cauliflower(Brassica oleracea L.var.botrytis)is a modified inflorescence that is consumed as a vegetable.Curd formation is proposed to be due to a mutation in the BobCAULIFLOWER(BobCAL)gene,but the genetic relationship between BobCAL variation and curd morphotypes remains obscure.To address this question,we collected and classified a collection of 78 cauliflower accessions into four subpopulations according to curd surface features:smooth,coarse,granular,and hairy curd morphotypes.Through the cDNA sequencing of BobCAL alleles,we showed that smooth and coarse accessions characterized by inflorescence meristem arrest presented a strong association with the 451T SNP(BobCAL_T),whereas granular and hairy accessions marked with floral organ arrest presented an association with 451G(BobCAL_G).Interestingly,all BobCAL alleles were alternatively spliced,resulting in a total of four alternative splice(AS)variants due to the retention of the fourth and/or seventh introns.Among accessions with BobCAL_G alleles,the total expression of all these AS variants in granular plants was almost equal to that in hairy plants;however,the expression of the individual AS variants encoding intact proteins relative to those encoding truncated proteins differed.Hairy accessions showed relatively high expression of the individual variants encoding intact proteins,whereas granular accessions displayed relatively low expression.In smooth cauliflower,the overexpression of the BobCAL_Ga variant caused an alteration in the curd morphotype from smooth to hairy,concurrent with an increase in the expression levels of downstream floral identity genes.These results reveal that alternative splicing of BobCAL transcripts is involved in the determination of cauliflower curd morphotypes.

A collection of 163 accessions,including Solanum pimpinellifolium,Solanum lycopersicum var.cerasiforme and Solanum lycopersicum var.lycopersicum,was selected to represent the genetic and morphological variability of tomato at its centers of origin and domestication:Andean regions of Peru and Ecuador and Mesoamerica.The collection is enriched with S.lycopersicum var.cerasiforme from the Amazonian region that has not been analyzed previously nor used extensively.The collection has been morphologically characterized showing diversity for fruit,flower and vegetative traits.Their genomes were sequenced in the Varitome project and are publicly available(***/projects/varitome).The identified SNPs have been annotated with respect to their impact and a total number of 37,974 out of 19,364,146 SNPs have been described as high impact by the SnpEeff analysis.GWAS has shown associations for different traits,demonstrating the potential of this collection for this kind of analysis.We have not only identified known QTLs and genes,but also new regions associated with traits such as fruit color,number of flowers per inflorescence or inflorescence architecture.To speed up and facilitate the use of this information,F2 populations were constructed by crossing the whole collection with three different parents.This F2 collection is useful for testing SNPs identified by GWAs,selection sweeps or any other candidate gene.All data is available on Solanaceae Genomics Network and the accession and F2 seeds are freely available at COMAV and at TGRC genebanks.All these resources together make this collection a good candidate for genetic studies.

In this contribution, we present iHEARu-PLAY, an online, multi-player platform for crowdsourced database collection and labelling, including the voice analysis application (VoiLA), a free web-based speech classification tool designed to educate iHEARu-PLAY users about state-of-the-art speech analysis paradigms. Via this associated speech analysis web interface, in addition, VoiLA encourages users to take an active role in improving the service by providing labelled speech data. The platform allows users to record and upload voice samples directly from their browser, which are then analysed in a state-of-the-art classification pipeline. A set of pre-trained models targeting a range of speaker states and traits such as gender, valence, arousal, dominance, and 24 different discrete emotions is employed. The analysis results are visualised in a way that they are easily interpretable by laymen, giving users unique insights into how their voice sounds. We assess the effectiveness of iHEARu-PLAY and its integrated VoiLA feature via a series of user evaluations which indicate that it is fun and easy to use, and that it provides accurate and informative results.

Genetic diversity and a population structure analysis of accessions in the Chinese cowpea [Vigna unguiculata(L.)Walp.]germplasm collection

作者： Honglin Chen Hong Chen Liangliang Hu Lixia Wang Suhua Wang Ming Li Wang Xuzhen Cheng National Key Facility for Crop Gene Resources and Genetic Improvement Institute of Crop Science Chinese Academy of Agricultural Sciences Development Center of Science and Technology Ministry of Agriculture PR China United States Department of Agriculture Agricultural Research Service Plant Genetic Resources Conservation Unit

Cowpea(Vigna imguicuiata) is an important legume crop with diverse uses. The species is presently a minor crop, and evaluation of its genetic diversity has been very limited. In this study, a total of 200 genic and 100 genomic simple sequence repeat(SSR) markers were developed from cowpea unigene and genome sequences, respectively. Among them, 27 genic and 27 genomic SSR markers were polymorphic and were used for assessment of genetic diversity and population structure in 105 selected cowpea accessions. A total of 155 alleles and 2.9 alleles per marker were identified, and the average polymorphic information content(PIC) value was 0.3615. The average PIC of genomic SSRs(0.3996) was higher than that of genic SSRs(0.3235), and most of the polymorphic genomic SSRs were composed of di-and trinucleotide repeats(51.9% and 37.0% of all loci, respectively). The low level of detected genetic diversity may be attributed to a severe genetic bottleneck that occurred during the cowpea domestication process. The accessions were classified by structure and cluster analysis into four subgroups that correlated well with their geographic origins or collection sites. The classification results were also consistent with the results from principal coordinate analysis and can be used as a guide during future germplasm collection and selection of accessions as breeding materials for cultivar improvement. The newly developed genic and genomic SSR markers described in this study will be valuable genomic resources for the assessment of genetic diversity, population structure, evaluation of germplasm accessions, construction of genetic maps, identification of genes of interest,and application of marker-assisted selection in cowpea breeding programs.
