At the end of 2019, Coronavirus disease (COVID-19) started and as of now, it is still the number one problem of the world today. This virus can be transmitted through droplets of saliva from an infected person which can be from a sneeze, cough, and exhales. As of now, there are a total of 111 million cases of the virus and there are technologies that were introduced to help in the detection of the infection and to reduce the spread of the virus. One of this technology is the Reverse Transcription-Polymerase Chain Reaction (RT-PCR) Machine. This machine detects any specific genetic material, including a virus. Samples from the body are treated with several chemical solutions which remove substances and only allow Ribonucleic Acid (RNA) to remain. But the problem with this machine is the elicitation of false-positive and false-negative results and certain malfunctions. Due to the issues in using RT-PCR, our team has come up with a newer and improvised version of the machine and called it COVIDBIT. COVIDBIT is a more simplified and portable version of the RT-PCR at a cheaper price. In this study, the team analyzed COVIDBIT as a virus detection device and an alternative for RT-PCR machine using SEM model and found out that there is a significant difference in terms of effectiveness and portability in usage and showed that the 210 respondents from the medical industry are most likely to use these kinds of machine.
2019年底,新型冠状病毒病(COVID-19)爆发,至今仍是当今世界的头号问题。这种病毒可以通过感染者打喷嚏、咳嗽和呼气时的唾液飞沫传播。到目前为止,总共有1.11亿例病毒病例,并引入了一些技术来帮助发现感染并减少病毒的传播。其中一项技术是逆转录聚合酶链反应(RT-PCR)机。这台机器可以检测任何特定的遗传物质,包括病毒。来自人体的样本用几种化学溶液处理,这些化学溶液可以去除物质,只允许核糖核酸(RNA)保留。但这台机器的问题是产生假阳性和假阴性结果以及某些故障。由于使用RT-PCR存在问题,我们的团队提出了一种更新的临时版本,并将其命名为covid - bit。covid - bit是一种更简化和便携的RT-PCR版本,价格更便宜。在这项研究中,团队使用SEM模型对covid - bit作为病毒检测设备和RT-PCR机的替代品进行了分析,发现在使用的有效性和便携性方面存在显著差异,并显示来自医疗行业的210名受访者最有可能使用这类机器。

Singularity Era: Computational Model of Entropy Within the Human Brain 奇点时代:人脑内熵的计算模型
Wenyu Ding, Tianyi Chen
What is the essence of thinking? The answer is human consciousness. If human beings do not have the ability to think independently, human beings will not be as advanced and complex as human beings are today, and there will be no countless radicals to explore the truth. Therefore, it is necessary to make a scientific inquiry into our consciousness. It is believed that entropy, as a crucial parameter in thermodynamics, is closely related to human consciousness, and information theory builds a good bridge for this connection. Modern technology has also laid a solid foundation for this, such as fMRI and EEG, to help humans better show the conscious activities in the brain and the relationship with system order. This paper will be divided into three parts one by one: Firstly, this paper outlines the computational framework of dynamic entropy in human brain cognition and nervous system; Then, it come up with two specific branches of research on entropy and human physiological phenomena, namely aging and dreaming with the reference of their corresponding medical treatment, so as to better understand the relationship between entropy and human consciousness. This paper also has the research value in some medical fields regarding to decrease the rate of aging and improve the quality of sleep.
思考的本质是什么?答案是人类的意识。如果人类没有独立思考的能力,人类就不会像今天的人类一样先进和复杂,也就不会有无数的激进派去探索真理。因此,有必要对我们的意识进行科学的探究。熵作为热力学中的一个重要参数,与人的意识密切相关,信息论为这种联系搭建了良好的桥梁。现代技术也为此奠定了坚实的基础,如功能磁共振成像(fMRI)和脑电图(EEG),帮助人类更好地展示大脑中的意识活动及其与系统秩序的关系。本文将依次分为三个部分:首先,概述了人脑认知和神经系统动态熵的计算框架;然后,提出了熵与人类生理现象的两个具体研究分支,即衰老和做梦,并参考其相应的医学治疗,从而更好地理解熵与人类意识的关系。本文在某些医学领域对于降低衰老速度,提高睡眠质量也有研究价值。

Dealing with Long-tail Issue in Diabetic Retinopathy and Diabetic Macular Edema Grading 处理糖尿病视网膜病变和糖尿病黄斑水肿分级的长尾问题
Yuze Xiao, Jianan Li, Shiqi Huang, Ning Shen, Jinhua Zhang, Fengwen Mi, Tingfa Xu
Diabetic Retinopathy (DR) is a multiply occurring complication induced by prolonged course of diabetes. Diabetic Macular Edema (DME) is the most common complication of DR which is the major threat of vision loss. Hence, it is urgently needed to expand the early screening and diagnosis via computer-assisted therapy. However, prior works mainly focus on investigating DR and DME in isolation, largely ignoring their inherent relationships. Besides, the fundus data distribution is typically long-tailed, with tail classes concentrating on critical levels of DME. Motivated by the distinctive complexion above, this work presents a novel position-guided attention block (PGAB) as well as an innovative label-sensitive (LS) loss, which are respectively in charge of extracting position-sensitive features to exploit interactions between hard exudate and macular and encouraging the model to embrace tail classes to lift the accuracy on critical levels of DME. Comprehensive experiments on popular Messidor and IDRiD datasets well demonstrate the superiority of our approach in achieving competitive performance compared to state-of-the-arts.
糖尿病视网膜病变(DR)是由糖尿病病程延长引起的多发病并发症。糖尿病性黄斑水肿(DME)是DR最常见的并发症,是视力丧失的主要威胁。因此,迫切需要通过计算机辅助治疗扩大早期筛查和诊断。然而,以往的研究工作主要集中在对DR和DME的单独研究上,很大程度上忽略了它们之间的内在关系。此外,眼底数据分布具有典型的长尾特征,尾类集中在DME的临界水平。受上述独特肤色的启发,本研究提出了一种新的位置引导注意力块(PGAB)和一种创新的标签敏感(LS)损失,它们分别负责提取位置敏感特征,以利用硬渗出液和黄斑之间的相互作用,并鼓励模型包含尾类,以提高DME在关键水平上的准确性。在流行的Messidor和IDRiD数据集上进行的综合实验很好地证明了与最先进的方法相比,我们的方法在实现竞争性性能方面的优越性。

Thermodynamic Calculation and Microstructure Optimization of Mg-Gd-Y-Zn-Zr Biodegradable Magnesium Alloy Mg-Gd-Y-Zn-Zr可生物降解镁合金热力学计算及微观结构优化
Jinjun Tang, Cui Liang, Chenguang Xu
In this paper, Thermo-Calc and CALPHAD calculation techniques are used to calculate and analyze the multivariate phase diagram, solidification path and microstructure content of biodegradable magnesium alloys with different components. The effects of elements y and Gd on the liquidus, phase distribution, strengthening phase content and microstructure of the alloy were discussed. Under the condition of non-equilibrium solidification, the primary MG24Y5 solid phase decreases and the (MG24Y5+MG3RE_D03) structure increases with the increase of Gd element. With the increase of Y element, the liquidus increased, the solid content of primary MG24Y5 increased, and the structure of (MG24Y5+MG3RE_D03) increased. With the simultaneous increase of Y and Gd elements, the liquidus increased, and the tissue content of (MG24Y5+MG3RE_D03) increased sharply. (MG24Y5+MG41RE5+HCP_A3) the content of residual tissue decreased. Zinc rich phases such as MgZn, MgZn2 and MG2ZN3, with relatively low content, are strengthening phases of solid solution and aging treatment, which play an important role in the mechanical properties of alloy materials. This paper solves the key technical problems of rapid degradation and poor uniformity of degradable magnesium alloy materials, obtains degradable magnesium alloy materials for stents with reliable quality, controllable degradation rate and excellent biocompatibility, forms relevant process standards and technical specifications, and verifies the feasibility of the application of this material technology in cardiovascular stent interventional therapy, Provide material basis and technical support for the further clinical application of the material.
本文采用thermal - calc和CALPHAD计算技术,对不同组分的可生物降解镁合金的多元相图、凝固路径和显微组织含量进行了计算和分析。讨论了元素y和Gd对合金液相线、相分布、强化相含量和显微组织的影响。在非平衡凝固条件下,随着Gd元素的增加,初生MG24Y5固相减少,(MG24Y5+MG3RE_D03)组织增多。随着Y元素的增加,液相线增加,初生MG24Y5固含量增加,(MG24Y5+MG3RE_D03)的结构增加。随着Y和Gd元素的同时增加,液相线增大,(MG24Y5+MG3RE_D03)的组织含量急剧增加。(MG24Y5+MG41RE5+HCP_A3)残余组织含量降低。富锌相MgZn、MgZn2和MG2ZN3含量相对较低,是固溶和时效处理的强化相,对合金材料的力学性能起着重要作用。本文解决了可降解镁合金材料降解快、均匀性差的关键技术问题,获得了质量可靠、降解率可控、生物相容性优异的支架用可降解镁合金材料,形成了相关的工艺标准和技术规范,验证了该材料技术应用于心血管支架介入治疗的可行性。为材料的进一步临床应用提供物质基础和技术支持。

Machine-Learning Based Drug and Supplement Design Platform for Chronic Disease Control 基于机器学习的慢性疾病控制药物和补充剂设计平台
Peter Qi
The emerging modern medical technology has provided treatment for a variety of major human diseases (including cancer, cardiovascular and cerebrovascular diseases, diabetes, etc.). However, the long-term control of these chronic diseases remains a challenge. These chronic diseases are the main cause of death and a major burden on public health. One key question in chronic disease management is how to develop efficacious and reliable drugs based on our emerging understanding of disease-related gene expression (from genes to drugs). In contrast, specific medical treatments such as surgery or chemotherapy of cancer often possess a small period over the entire course of chronic disease management, meanwhile the therapy outcomes of chronic diseases also largely depend on the long-term lifestyles of the patients, such as mood and diet. Given the large quantity and complexity of traditional medical data, it is difficult to manually evaluate the impact of diets or nutrition on chronic disease control (from drugs to supplements/nutrition). This project aimed to systematically analyze disease-related gene expression data for drug development and to specify a dietary plan for specific chronic disease recovery from health big data and individualized data of patients. Using multiple gene-to-drug algorithms combined with Random Forest machine learning tools, I have discovered decamethonium bromide as a broad-spectrum anti-cancer drug targeting currently “undruggable” oncogenes and tumor suppressors and investigated honeysuckle as a potential supplement.

新兴的现代医疗技术为人类多种重大疾病(包括癌症、心脑血管疾病、糖尿病等)提供了治疗。然而,长期控制这些慢性疾病仍然是一项挑战。这些慢性疾病是造成死亡的主要原因,也是公共卫生的主要负担。慢性疾病管理的一个关键问题是如何根据我们对疾病相关基因表达的新认识(从基因到药物)开发有效可靠的药物。相比之下,特定的医学治疗,如癌症的手术或化疗,往往在整个慢性病治疗过程中占据很小的时间,同时慢性病的治疗效果也在很大程度上取决于患者的长期生活方式,如情绪和饮食。由于传统医学数据的数量和复杂性,很难人工评估饮食或营养对慢性疾病控制的影响(从药物到补充剂/营养)。本项目旨在通过健康大数据和患者个体化数据,系统分析疾病相关基因表达数据,为药物研发提供依据,制定针对特定慢性疾病康复的饮食计划。使用多种基因-药物算法结合随机森林机器学习工具,我发现了十甲基溴作为一种广谱抗癌药物,靶向目前“无法药物”的癌基因和肿瘤抑制因子,并研究了金银花作为潜在的补充。CCS概念·应用计算·生命与医学·计算生物学

Development of an Automatic Pellet Dispenser for Forelimb Grasping Experiments in Rodents 用于啮齿动物前肢抓取实验的自动颗粒分配器的研制
Shifeng Li, Canhui Zeng, Rongchao Peng, Shan Ma
Forelimb grasping experiments are important for investigating the performance of the locomotor system and the learning ability. Due to lack of automatic machines, manual operation is a heavy load for experimenters. Therefore, we developed an automatic pellet dispenser using the Arduino Nano board. The user puts a bucket of food pellets into the storage pool, the machine automatically disperses them and delivers a single pellet to a fixed position in the food plate. When the pellet is taken by the animal, then it delivers another. The system is composed of the Arduino Nano board, a stepper motor, two servo motors, two photo sensors, a display and three buttons. It is inexpensive and easy to use. When tested, it ran orderly and stably. We hope it can help in repetitive experiments, reduce the manual load and save a lot of time.
前肢抓握实验对研究运动系统性能和学习能力具有重要意义。由于缺乏自动机器,手工操作对实验人员来说是一项繁重的工作。因此,我们利用Arduino Nano板开发了一种自动颗粒分配器。用户将一桶食物颗粒放入储存池中,机器自动将其分散,并将单个颗粒输送到食物盘中的固定位置。当小颗粒被动物吃掉后,它会释放另一个颗粒。该系统由Arduino Nano板、一个步进电机、两个伺服电机、两个光电传感器、一个显示器和三个按钮组成。它既便宜又容易使用。经测试,运行有序、稳定。我们希望它可以帮助重复实验,减少人工负荷,节省大量的时间。

Effect of Hypomagnetic Field on Hypocotyl Growth in Arabidopsis 低磁场对拟南芥下胚轴生长的影响
Shanshan Feng, Chunxiao Xu
Cryptochrome was thought of as a magnetoreceptor based on the proposal that photochemical reactions worked as the sensor of geomagnetic field (GMF). To test the effect of GMF on cryptochrome, we created a hypomagnetic field environment by eliminating the local GMF using Helmholtz coils and grew wild-type Arabidopsis and cryptochrome double mutant, cry1/cry2, in the hypomagnetic field under blue light. We found that hypocotyl length of wild-type Arabidopsis rather than cry1/cry2 mutants was longer in hypomagnetic field than in local GMF. Moreover, we detected gibberellin (GA) levels in Arabidopsis in hypomagnetic field and found that GA4 and GA9 were increased in wild-type seedlings instead of cry1/cry2 mutants. Furthermore, transcription of GA20-oxidase genes (GA20ox1, GA20ox2, and GA20ox3) and GA3-oxidase genes (GA3ox1, GA3ox2, GA3ox3, and GA3ox4) was enhanced. Our results indicate that hypomagnetic field suppresses blue light-dependent inhibition of hypocotyl growth in Arabidopsis, and that cryptochrome and GAs are involved in the effect of hypomagnetic field on hypocotyl growth.
隐花色素是一种磁感受器,这是基于光化学反应作为地磁场传感器的建议。为了验证GMF对隐花色素的影响,我们利用亥姆霍兹线圈在弱磁场环境中消除局部GMF,在蓝光下培养野生型拟南芥和隐花色素双突变体cry1/cry2。结果表明,与cry1/cry2突变体相比,野生型拟南芥的下胚轴长度在弱磁场条件下比在局部GMF条件下更长。此外,我们检测了低磁场下拟南芥中赤霉素(gibberellin, GA)的含量,发现野生型幼苗中GA4和GA9的含量增加,而cry1/cry2突变体幼苗中GA4和GA9的含量增加。此外,ga20氧化酶基因(GA20ox1、GA20ox2和GA20ox3)和ga3氧化酶基因(GA3ox1、GA3ox2、GA3ox3和GA3ox4)的转录增强。我们的研究结果表明,低磁场抑制蓝光依赖性的拟南芥下胚轴生长,隐色素和GAs参与了低磁场对下胚轴生长的影响。

The Relationship Between Pulse Rate and Mandarin Tone Recognition: A Preliminary Study with CCi-Mobile Cochlear Implant Research Processor 基于cci -移动人工耳蜗研究处理器的脉搏率与普通话声调识别关系的初步研究
Yefei Mo, Huali Zhou, Q. Meng, Peina Wu
The aim of this study is to evaluate the effects of pulse rate (i.e., stimulation rate) on Mandarin tone recognition by cochlear implant users. Mandarin tone recognition was measured by using monosyllabic and disyllabic tone data-bases at three pulse rates in cochlear implant users. The three pulse rates included each participant's clinical default pulse rate (i.e., 900 or 1200 pulses per second (pps) for each electrode), 400 pps, and 200 pps. A real-time research speech processor, CCi-Mobile, was used to implement the signal processing strategies. Although the results are variable among participants, there was a trend that the recognition rates of both monosyllabic and disyllabic databases decreased with lower pulse rates, indicating that low pulse rates degrade acoustic cues, like periodicity, for Mandarin tone perception. This study also provided preliminary data for evaluating the CCi-Mobile research processor for the first time in China. The processor could be used for signal processing algorithm development and psychophysical experiments in the future.
本研究的目的是评估脉冲频率(即刺激频率)对人工耳蜗使用者普通话语音识别的影响。使用单音节和双音节声调数据库测量人工耳蜗使用者在三种脉冲速率下的普通话声调识别。这三种脉搏率包括每个参与者的临床默认脉搏率(即每个电极每秒900或1200次脉搏),400和200次脉搏。采用实时语音处理器CCi-Mobile来实现信号处理策略。虽然结果在参与者之间存在差异,但有一个趋势是,单音节和双音节数据库的识别率都随着脉冲率的降低而降低,这表明低脉冲率降低了普通话声调感知的声学线索,如周期性。本研究也为国内首次评价CCi-Mobile研究处理器提供了初步数据。该处理器可用于信号处理算法开发和心理物理实验。

Design of a STM32 based Portable System for Postpartum Recovery 基于STM32的便携式产后康复系统设计
Xiaolin Lu, D. Chen, Shan Ma
Postpartum rehabilitation is one of the issues that pregnant women are very concerned about. In order to facilitate the postpartum rehabilitation nursing of spontaneous parturients, assist the restoration of uterus and save labor cost, this paper designs a non-invasive and easy to operate portable low-frequency pulse postpartum rehabilitation system to help parturients alleviate their physical and mental pressure and reduce their postpartum discomfort. The system uses stm32f103rct6 as the core controller, takes the belt as the carrier, and combines the pressure control module, temperature control module and low-frequency pulse module. The pressure control module is composed of pressure sensor, airbag and air pump. The temperature control module consists of a temperature sensor and a heating plate. STM32 collects the data of each module for analysis and processing, and transmits the data to mobile app or PC through Bluetooth module. The system can not only realize the functions of low-frequency pulse current massage, pelvic pressurization and dew discharge, temperature control and heat preservation, but also be safe, reliable and practical.
