| 1 | 基于深度学习的羊脸检测与识别方法显示文摘家畜个体身份的精准识别对于动物行为研究和现代化选种选配具有重要价值,目前家畜身份的确定主要依据图像或视频中所存在的动物的脸部特征而展开。该文以羊脸识别为目标,提出了基于多种深度学习方法的羊脸检测与识别方案。对羊脸在图片中的位置进行框选和定位,将检测到的来自不同图片的羊脸区分开来,进行个体身份鉴定。采集来自同一群体的形态相近的35只奶山羊的共3121张图片,制作了羊的全身数据集和羊脸数据集。在羊脸框选定位阶段,当随机选取900张羊脸图片做训练,102张羊脸图片做测试时,使用深度学习YOLOv3算法检测到羊脸的正确率可达97%以上;基于可检测到羊脸数据集进行个体识别时,使用深度学习VGGFace模型仅能取得约64%左右识别准确率;而当选取其中616张正面羊脸作为训练集及198张正面羊脸作为测试集时,VGGFace预训练模型的识别准确率可达91%以上。试验结果表明,基于深度学习模型的羊脸检测效果较为理想,而羊脸识别工作则仅在正面羊脸上取得了较高的准确率,其它视角的羊脸识别工作仍有待进一步的研究。 | 魏斌 Masum Billah 王美丽 尚诚 于建涛 姜雨 | 2022 | 家畜生态学报2022，43，3： | 5 |
| 2 | Hybrid multi-chip assembly of optical communication engines by in situ 3D nanolithography显示文摘Three-dimensional(3D)nano-printing of freeform optical waveguides,also referred to as photonic wire bonding,allows for efficient coupling between photonic chips and can greatly simplify optical system assembly.As a key advantage,the shape and the trajectory of photonic wire bonds can be adapted to the mode-field profiles and the positions of the chips,thereby offering an attractive alternative to conventional optical assembly techniques that rely on technically complex and costly high-precision alignment.However,while the fundamental advantages of the photonic wire bonding concept have been shown in proof-of-concept experiments,it has so far been unclear whether the technique can also be leveraged for practically relevant use cases with stringent reproducibility and reliability requirements.In this paper,we demonstrate optical communication engines that rely on photonic wire bonding for connecting arrays of silicon photonic modulators to InP lasers and single-mode fibres.In a first experiment,we show an eight-channel transmitter offering an aggregate line rate of 448 Gbit/s by low-complexity intensity modulation.A second experiment is dedicated to a four-channel coherent transmitter,operating at a net data rate of 732.7 Gbit/s-a record for coherent silicon photonic transmitters with co-packaged lasers.Using dedicated test chips,we further demonstrate automated mass production of photonic wire bonds with insertion losses of(0.7±0.15)dB,and we show their resilience in environmental-stability tests and at high optical power.These results might form the basis for simplified assembly of advanced photonic multi-chip systems that combine the distinct advantages of different integration platforms. | Matthias Blaicher Muhammad Rodlin Billah Juned Kemal Tobias Hoose Pablo Marin-Palomo Andreas Hofmann Yasar Kutuvantavida Clemens Kieninger Philipp-Immanuel Dietrich Matthias Lauermann Stefan Wolf Ute Troppenz Martin Moehrle Florian Merget Sebastian Skacel Jeremy Witzens Sebastian Randel Wolfgang Freude Christian Koos | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 3 | Phytochemical and in vitro biological investigations of methanolic extracts of Enhydra fluctuans Lour显示文摘Objective:To study the phytochemical and biological properties(antioxidant,anthelmintic and thrombolytic)of methanolic extracts of Enhydra fluctuant Lour.,a plant belonging to the Asteraceae family.Methods:The phytochemical evaluation was carried out by qualitative analysis.In vitro antioxidant activity of extract was studied using free radical scavenging assay,ability of reduction,total phenol and total flavonoid contents determination assays.The anthelmintic activity was determined using paralysis and death time of Pheretima posthuma(earthworm)and thrombolytic activity by clot disruption assay.Results:The phytochemical evaluation showed significant presence of flavonoids,triterpenes,carbohydrate,reducing sugars,saponins,phenols,diterpenes,protein and tannin.The antioxidant activity was found significant[IC_(50)(135.20±036)μg/mL]as compared to ascorbic acid[(130.00±0.76)μg/mL].The reducing power was increased with concentration.Total phenol and total flavonoid contents were(153.08±0.38)mg/mL and(172.04±0.56)mg/mL respectively.The paralysis and death time of earthworms for different concentrations of extract were determined and compared with albendazole.The results showed that 10 mg/mL of the crude extract had similar effect with albendazole.Additionally,the crude extract showed a concentration depended relationship with its anthelmintic property.The clot lysis activity of crude extract was compared to the standard streptokinase's clot lysis(40.13%)activity and found significant(31%).Conclusions:The study proves that the crude methanolic extract of Enhydra fluctuant Lour,has significant antioxidant,anthelmintic and thrombolytic activity containing wide range of phytochemicals. | Sourov Kuri Mustahsan Billah S.M.Masud Rana Zannatul Naim Mahmodul Islam Hasanuzzaman Ramjan Ali Rana Banik | 2014 | Asian Pacific Journal of Tropical Biomedicine2014，4，4： | 2 |
| 4 | Unsupervised method of clustering and labeling of the online product based on reviews显示文摘This paper presents an unsupervised approach to cluster reviews of products collected from Amazon and then generates its labels of each cluster.Instead of using a complete review,this paper splits a review into sentences and considers all sentences from the reviews as inputs for Clustering.Hierarchical Agglomerative Clustering(HAC)is used to cluster sentences.The approaches of cluster labeling are also unsupervised.For labeling,three different methods have been used to find a limited number of essential words for each cluster.Extracted essential words are used to construct phrases.Constructed phrases are used as labels for each cluster.This paper compares the result of the labeling method with baseline labeling.In the result evaluation,all the labeling methods outperform the baseline method.The aim of this research is cluster labeling that makes a set of labels to describe a cluster content and distinguishes the labels from other cluster labels. | Md Masum Billah Mohammad Nuruzzaman Bhuiyan Md.Akterujjaman | 2021 | International Journal of Modeling, Simulation, and Scientific Computing2021，12，2： | 2 |
