| 1 | Infrared upconversion imaging in nonlinear metasurfaces显示文摘Infrared imaging is a crucial technique in a multitude of applications,including night vision,autonomous vehicle navigation,optical tomography,and food quality control.Conventional infrared imaging technologies,however,require the use of materials such as narrow bandgap semiconductors,which are sensitive to thermal noise and often require cryogenic cooling.We demonstrate a compact all-optical alternative to perform infrared imaging in a metasurface composed of GaAs semiconductor nanoantennas,using a nonlinear wave-mixing process.We experimentally show the upconversion of short-wave infrared wavelengths via the coherent parametric process of sum-frequency generation.In this process,an infrared image of a target is mixed inside the metasurface with a strong pump beam,translating the image from the infrared to the visible in a nanoscale ultrathin imaging device.Our results open up new opportunities for the development of compact infrared imaging devices with applications in infrared vision and life sciences. | Rocio Camacho-Morales Davide Rocco Lei Xu Valerio Flavio Gili Nikolay Dimitrov Lyubomir Stoyanov Zhonghua Ma Andrei Komar Mykhaylo Lysevych Fouad Karouta Alexander Dreischuh Hark Hoe Tan Giuseppe Leo Costantino De Angelis Chennupati Jagadish Andrey E.Miroshnichenko Mohsen Rahmani Dragomir N.Neshev | 2021 | Advanced Photonics2021，3，3： | 11 |
| 2 | 高强度聚焦超声治疗不能手术胰腺癌的1年生存分析:中国和保加利亚的多中心临床研究显示文摘目的:通过多中心临床研究分析高强度聚焦超声治疗不能手术胰腺癌的1年生存情况。方法:2013年1月到2014年1月,中国和保加利亚的不能手术的胰腺癌患者32例,男/女=20/12,年龄41~81(59.8±9.1)岁。胰腺癌病灶最大径20~60(39.3±9.6)mm,远处转移/无转移的患者18/14例。接受HIFU和/或化疗。记录术后并发症,疼痛变化和生存情况。使用Kaplan-Meier法计算总生存率和中位生存时间,比较化疗与否、是否发生远处转移的患者生存率有无差异(Log-Rank检验)。结果:术后1月,皮肤浅Ⅱ°烧伤者2例,经保守处理后1~2周愈合。伴有胰腺癌相关性疼痛症状的患者30例与术前比较,减轻的24例(80.0%),不变的5例(16.7%),加重的1例(3.3%)。所有患者的1年生存率为38.4%,中位生存时间为12个月。接受辅助化疗的患者1年生存率为57.4%,中位生存时间12月;未接受辅助化疗的患者1年生存率为20.8%,中位生存时间为6月;二者间比较有显著性差异。伴有远处转移的患者1年生存率为0%,中位生存时间为7月;无远处转移的患者1年生存率为49.2%,中位生存时间为12月;二者间比较无统计学差异。结论:中国和保加利亚的不能手术胰腺癌患者均能安全完成HIFU治疗,1年生存率和中位生存时间优于其它非手术治疗手段。辅助化疗能增加生存受益,远处转移是预后不良因素。 | 周崑 Dobromir Dimitrov Dimitrov Tihomir Vencislavov Andreev 汪亮 Hyuliya Erdzhanova Feradova Grigor Angelov Gorchev 朱辉 王智彪 | 2015 | 重庆医科大学学报2015，40，3： | 11 |

| 4 | Does gastric atrophy exist in children?显示文摘Several clinical reports confirmed that gastric atrophy is a pathology not only limited to adult patients. In pediatrics, it is most often described in association with a H pylori infection but this bacteria does not seem to be the only etiological factor of this preneoplastic state in children. The frequency of gastric atrophy and intestinal metaplasia in children are unknown because they are not systematically sought during upper gastrointestinal endoscopy. The lack of specific histological classification of children’s gastropathies makes their diagnosis difficult for pathologists. Based on our knowledge to date, we think that it is necessary to describe, in detail, the natural course of this lesion during childhood. A close and prolonged clinical and endoscopic follow-up is important for children with gastric atrophy. | Georges Dimitrov Frédéric Gottrand | 2006 | World Journal of Gastroenterology2006，12，39： | 5 |
| 5 | Statistical Estimation of the Shannon Entropy显示文摘The behavior of the Kozachenko–Leonenko estimates for the(differential) Shannon entropy is studied when the number of i.i.d. vector-valued observations tends to infinity. The asymptotic unbiasedness and L^2-consistency of the estimates are established. The conditions employed involve the analogues of the Hardy–Littlewood maximal function. It is shown that the results are valid in particular for the entropy estimation of any nondegenerate Gaussian vector. | Alexander BULINSKI Denis DIMITROV | 2019 | Acta Mathematica Sinica,English Series2019，35，1： | 4 |
| 6 | 批量下载GenBank基因序列数据的新工具--NCBIminer显示文摘核苷酸序列是生物体遗传信息的载体,是现代生物学和生态学的基础数据。随着测序技术的进步,大量核苷酸序列被提取并存储在公共数据平台中,其中Gen Bank(http://gffzz16a62c593b5540ceh55p6qukvun9n6pc0.ffgz.tsg.suse.edu.cn/genbank/)是目前最大的核苷酸序列数据平台之一。截至2015年2月,该平台收录核苷酸序列总数已超过1.8亿条、覆盖全球超过30万个物种。但如何从如此海量的数据中准确、快速查找并下载所需数据已成为限制基因数据广泛使用的障碍之一。为此,我们开发了一款可高效、准确下载Gen Bank数据的生物信息学软件NCBIminer。NCBIminer可根据用户提供的核苷酸序列名称、数据类型、一或多条初始化参考序列,查找并下载用户指定的多个物种或类群的特定基因序列数据。该软件下载地址为http://gffzz188fe103f8f1460as55p6qukvun9n6pc0.ffgz.tsg.suse.edu.cn/greengirl/NCBIminer/releases/,可在Windows、Linux和MAC操作系统下免费使用;同时,其操作简单,用户无需生物信息学背景。为方便该软件的使用,本文将介绍该软件的工作流程与算法、安装及使用过程中的参数设置等。 | 徐晓婷 王志恒 Dimitar Dimitrov Carsten Rahbek | 2015 | 生物多样性2015，23，4： | 3 |
| 7 | 基于氧传感器信号的用于研究空气/燃料比率变化的统计方法显示文摘给出了火花点火式发动机排气氧传感器(EGO)输出信号的实验结果。实验中采用V6、3.8 L、BUICK发动机且每个气缸中安装有一个氧传感器,以研究影响发动机消耗燃料的因素。应用LabView数据采集装置记录单个气缸废气以及主流尾气氧传感器的输出电压信号。对来自6个气缸变量的平均值采用统计的方法进行处理后,并与主流的EGO电压进行比较,确定了产生系统误差的因素。对左右两侧气缸信号平均值的差别进行比较发现,采用此种排气管结构的气缸中空气—燃料混合气平均值存在一些明显差别。根据数据和图表解释了统计的结果。研究表明,V字形排列的发动机两侧的气缸的空气和燃料混合气是不同的;在低速、高负荷和高辛烷燃料的情况下,右侧气缸具有比较稀的混合气;而在某些情况下两侧气缸具有相同的混合气。基于统计估计的方法,提出了一个可以用于估计V字形排列发动机左右两侧气缸中空气—燃料混合气的简单模型。此方法还可以应用于分析进气管和排气管的缺陷。 | Etim U Ubong Boyan Dimitrov | 2008 | 内燃机学报2008，26，1： | 3 |
| 8 | The Character and Formation of Elongated Depressions on the Upper Bulgarian Slope显示文摘Seafloor elongated depressions are indicators of gas seepage or slope instability. Here we report a sequence of slopeparallel elongated depressions that link to headwalls of sediment slides on upper slope. The depressions of about 250 m in width and several kilometers in length are areas of focused gas discharge indicated by bubble-release into the water column and methane enriched pore waters. Sparker seismic profiles running perpendicular and parallel to the coast, show gas migration pathways and trapped gas underneath these depressions with bright spots and seismic blanking. The data indicate that upward gas migration is the initial reason for fracturing sedimentary layers. In the top sediment where two young stages of landslides can be detected, the slopeparallel sediment weakening lengthens and deepens the surficial fractures, creating the elongated depressions in the seafloor supported by sediment erosion due to slope-parallel water currents. | XU Cuiling GREINERT Jens HAECKEL Matthias BIALAS Jorg DIMITROV Lyubomir ZHAO Guangtao | 2018 | Journal of Ocean University of China2018，17，3： | 2 |

| 10 | Projected effectiveness of HIV detection during early infection and rapid ART initiation among MSM and transgender women in Peru: A modeling study显示文摘Background:The Sabes study,a treatment as prevention intervention in Peru,tested the hypothesis that initiating antiretroviral therapy(ART)early in HIV infection when viral load is high,would markedly reduce onward HIV transmission among high-risk men who have sex with men(MSM)and transgender women(TW).We investigated the potential population-level benefits of detection of HIV early after acquisition and rapid initiation of ART.Methods:We designed a transmission dynamic model to simulate the HIV epidemic among MSM and TW in Peru,calibrated to data on HIV prevalence and ART coverage from 2004 to 2011.We assessed the impact of an intervention starting in 2018 in which up to 50%of the new infections were diagnosed within three months of acquisition and initiated on ART within 1 month of diagnosis.We estimated the impact of the intervention over 20 years using the cumulative prevented fraction of new HIV infections compared to scenarios without intervention.Findings:Our model suggests that only 19%of the infected MSM and TW are virally suppressed in 2018 and 35%e40%of the new HIV infections are transmitted from contacts with acutely-infected partners.An intervention reaching 10%of all acutely infected MSM and TW is projected to prevent 13.3%[Uncertainty interval:11.9%e14.3%]of the new infections over 20 years and reduce HIV incidence in 2038 by 24%.Reaching 50%of all acutely infected MSM and TWwill increase the prevalence of viral suppression in 2038 to 59%and prevent 41%of expected infections over 20 years.Reaching 50%of the high-risk MSM and TW in acute phase would reduce HIV incidence in 2038 by 60%and prevent 36%of new infections between 2018 and 2038.Conclusions:Early detection of HIV infections and rapid initiation of ART among MSM is desirable as it would increase the effectiveness of the HIV prevention program in Peru.Targeting high-risk MSM and TW will be highly efficient. | Dobromir Dimitrov Daniel Wood Angela Ulrich David A.Swan Blythe Adamson Javier R.Lama Jorge Sanchez Ann Duerr | 2019 | Infectious Disease Modelling2019，4，1： | 2 |
