Smartphone-based transport mode detection for elderly care 基于智能手机的养老交通方式检测
N. Cardoso, João Madureira, N. Pereira
Smartphones are everywhere, and they are a very attractive platform to perform unobtrusive monitoring of users. In this work, we use common features of modern smartphones to build a human activity recognition (HAR) system for elderly care. We have built a classifier that detects the transport mode of the user including whether an individual is inactive, walking, in bus, in car, in train or in metro. We evaluated our approach using over 24 hours of transportation data from a group of 15 individuals. Our tests show that our classifier can detect the transportation mode with over 90% accuracy.
智能手机无处不在,它们是一个非常有吸引力的平台,可以对用户进行不显眼的监控。在这项工作中,我们利用现代智能手机的共同特征来构建老年人护理的人类活动识别(HAR)系统。我们已经建立了一个分类器,可以检测用户的交通方式,包括个人是否不活动,步行,乘坐公共汽车,汽车,火车或地铁。我们使用15个人的24小时交通数据来评估我们的方法。我们的测试表明,我们的分类器可以以90%以上的准确率检测运输方式。

Patient-aware adaptive ngram-based algorithm for epileptic seizure prediction using EEG signals 基于脑电信号的患者感知自适应脑图癫痫发作预测算法
Hussein Alawieh, H. Hammoud, Mortada Haidar, M. Nassralla, Ahmad M. El-Hajj, Z. Dawy
This work proposes a novel patient-aware approach that utilizes an n-gram based pattern recognition algorithm to analyze scalp electroencephalogram (EEG) data and predict epileptic seizures. The method addresses the major challenge of extracting distinctive features from EEG signals through a detection of spatio-temporal signatures related to neurological events. By counting the number of occurrences of amplitude patterns with predefined lengths, the algorithm generates a probabilistic measure (anomalies ratio) that is used as a prediction marker. These extracted ratios are classified using state of the art machine learning algorithms into seizure and non-seizure windows. The efficacy of the prediction model is tested on patient records from the Freiburg database with more than 100 hours of recordings per patient and for a total of 145 seizures. The proposed algorithm is further optimized to obtain the n-gram parameters for enhanced feature extraction. Results demonstrate an average accuracy of 93.83%, sensitivity of 96.12%, and false alarm rate of 8.44%.
这项工作提出了一种新的患者感知方法,该方法利用基于n图的模式识别算法来分析头皮脑电图(EEG)数据并预测癫痫发作。该方法通过检测与神经事件相关的时空特征,解决了从脑电图信号中提取显著特征的主要挑战。通过计算具有预定义长度的振幅模式的出现次数,该算法生成一个用作预测标记的概率度量(异常比率)。这些提取的比率使用最先进的机器学习算法分为癫痫发作和非癫痫发作窗口。预测模型的有效性在Freiburg数据库的患者记录上进行了测试,每个患者的记录超过100小时,总共有145次癫痫发作。进一步优化算法,得到n-gram参数,增强特征提取。结果表明,平均准确率为93.83%,灵敏度为96.12%,虚警率为8.44%。

Immediate and long-term effects of 2016 Zika Outbreak: A Twitter-based study 2016年寨卡病毒爆发的即时和长期影响:一项基于twitter的研究
A. Khatua, Apalak Khatua
Twitter is becoming a popular social media platform for syndromic surveillance. We explored the Twitter discussion in the context of the 2016 Zika Outbreak. The Zika virus can have severe long-term (such as microcephaly in newborns) effects and not so serious immediate (such as fever or headache) effects. We explored whether social media discussions effectively capture the severity of these long-term concerns. We performed volumetric and text mining analysis, such as the co-occurrence of words and hierarchical clustering, to explore the different underlying themes in the Twitter discussion regarding the immediate and long-term concerns. Our findings suggest that the concerns related to the long-term consequences are dominant and consistent, but this is not the case for the immediate effects.
推特正在成为一个流行的综合征监测社交媒体平台。我们在2016年寨卡病毒爆发的背景下探讨了推特上的讨论。寨卡病毒可造成严重的长期影响(如新生儿小头症),也可造成不那么严重的即时影响(如发烧或头痛)。我们探讨了社交媒体讨论是否有效地捕捉到了这些长期问题的严重性。我们执行了容量和文本挖掘分析,例如词的共现和分层聚类,以探索Twitter讨论中关于当前和长期关注点的不同潜在主题。我们的研究结果表明,与长期后果有关的担忧是主要的和一致的,但这不是立即影响的情况。

Application of recommender system methods for therapy decision support 推荐系统方法在治疗决策支持中的应用
F. Gräßer, H. Malberg, S. Zaunseder, Stefanie Beckert, D. Küster, Jochen Schmitt, S. Abraham
In this paper two approaches for facilitating therapy decision support are proposed and compared. Both approaches, the Collaborative Recommender and hybrid Demographic-based Recommender, are based on recommender system methods which origin from the field of product recommendation in e-commerce applications. An exemplary dataset comprising health record excerpts of patients suffering from the skin disease psoriasis is used for evaluating both approaches. The approaches estimate the outcome of a subset of systemic therapies to support the medical practitioner in making therapy decisions for a specific patient and time, i.e. consultation under consideration. Both systems proved to work and are capable of assisting medical practitioners prospectively with making appropriate therapy decisions.

A concept for consistent and prioritized presentation of surgical information 一个一致的和优先的外科信息呈现的概念
Erik Schreiber, S. Franke, R. Bieck, T. Neumuth
With each newly developed surgical assistance functionality, more information is available but also required in the operating room (OR). To prevent an information overload and support the surgical workflow, we propose a concept for a prioritized and consistent presentation of surgical information. We identify necessary tasks and requirements to present the right information, to the right time, at the right place and in the right form. For this, rule-based methods to prioritize information in respect to its relevance to the current OR situation and to orchestrate information consistently on a set of OR monitors are designed. Subsequently advantages and disadvantages of the proposed approach are discussed and next required steps for an implementation elucidated.
随着每一个新开发的手术辅助功能,更多的信息是可用的,但也需要在手术室(OR)。为了防止信息过载并支持手术工作流程,我们提出了一个优先级和一致的手术信息呈现的概念。我们确定必要的任务和要求,以便在正确的时间、正确的地点、以正确的形式呈现正确的信息。为此,设计了基于规则的方法,根据信息与当前OR情况的相关性对信息进行优先级排序,并在一组OR监视器上一致地编排信息。随后讨论了所建议的方法的优点和缺点,并阐明了实现的下一步所需步骤。

Wireless optogenetic neural dust for deep brain stimulation 用于深部脑刺激的无线光遗传神经尘埃
Stefanus A. Wirdatmadja, S. Balasubramaniam, Y. Koucheryavy, J. Jornet
In recent years, numerous research efforts have been dedicated towards developing efficient implantable devices for Deep Brain Stimulation (DBS). However, there are limitations and challenges with the current technologies. Firstly, the stimulation of neurons currently is only possible through implantable electrodes which target a population of neurons. This results in challenges in the event that stimulation at the single neuron level is required. Secondly, a major hurdle still lies in developing miniature devices that can last for a lifetime in the patient's brain. Recently, the concept of neural dust has been introduced as a way to achieve single neuron monitoring and potentially actuation. In parallel to this, the field of optogenetics has emerged where the aim is to stimulate neurons using light, usually by means of optical fibers inserted through the skull. Obviously, this introduces many challenges in terms of user friendliness and biocompatibility. We address this shortcoming by proposing the wireless optogenetic neural dust (wi-opt neural dust). The wiopt neural dust is equipped with a miniature LED that is able to stimulate the genetically engineered neurons, and at the same time harvest energy from ultrasonic vibrations. The simulation results presented in the paper investigates the behaviour of the light propagation in the brain tissue, as well as the performance of designed circuitry for the energy harvesting process. The results demonstrates the feasibility of utilizing wi-opt neural dust for long term implantation in the brain, and a new direction towards precise stimulation of neurons in the cortex.
近年来,许多研究都致力于开发高效的植入式脑深部刺激(DBS)装置。然而,目前的技术也存在局限性和挑战。首先,对神经元的刺激目前只能通过植入式电极来实现,这种电极针对的是一群神经元。这导致了在需要单个神经元水平刺激的情况下的挑战。其次,一个主要障碍仍然在于开发能够在患者大脑中使用一生的微型设备。最近,神经尘埃的概念被引入,作为实现单个神经元监测和潜在驱动的一种方法。与此同时,光遗传学领域也出现了,其目的是用光刺激神经元,通常是通过将光纤插入颅骨。显然,这在用户友好性和生物相容性方面带来了许多挑战。我们通过提出无线光遗传神经尘埃(wi-opt神经尘埃)来解决这一缺点。wiopt神经粉尘配备了一个微型LED,能够刺激基因工程神经元,同时从超声波振动中收集能量。本文的模拟结果研究了光在脑组织中的传播行为,以及设计的能量收集过程电路的性能。结果表明,利用wi-opt神经粉尘在大脑内长期植入的可行性,为精确刺激皮层神经元开辟了新的方向。

Adaption of medical information system's e-learning extension to a simple suggestion tool 将医疗信息系统的电子学习扩展到一个简单的建议工具
P. Rajković, D. Jankovic, A. Milenković
Developing suggestion tools in the scope of health information systems can be a complex task, followed by a risk of not being accepted by the end users. Thus, we decide to start the implementation around the existing functionality. In this paper we present a case study showing the adaptation of e-learning medical information system extension to a set of simple suggestion tools. While some features of initial system had to be modified, the domain specific knowledge collected for the e-learning extension is used to suppress potential errors. Presented suggestion tool is based on highly configurable lists of pre-defined entities that can be easily selected, and after the verification from the medical practitioner, copied into an active visit. After four years of active use, and several iteration of update, described suggestion tools are mostly accepted among the general practitioners, especially within certain scenarios where faster medication prescription is a must.
在卫生信息系统范围内开发建议工具可能是一项复杂的任务,随之而来的是不被最终用户接受的风险。因此,我们决定围绕现有功能开始实现。在本文中,我们提出了一个案例研究,展示了电子学习医疗信息系统扩展到一套简单的建议工具的适应。在修改初始系统的某些特征时,利用为电子学习扩展而收集的领域特定知识来抑制潜在的错误。提出的建议工具基于高度可配置的预定义实体列表,这些列表可以很容易地选择,并在医生验证后复制到主动访问中。经过四年的积极使用和几次迭代更新,描述的建议工具在全科医生中大部分被接受,特别是在必须快速用药的某些情况下。

A simple and accurate matrix for model based photoacoustic imaging 基于模型的光声成像简单准确的矩阵
K. J. Francis, P. Mishra, P. Rajalakshmi, Sumohana S. Channappayya, A. Richhariya
Accurate model-based methods in Photo-Acoustic Tomography (PAT) can reconstruct the image from insufficient and inaccurate measurements. Most of the models either make the simplified assumption of spherical averaging or use accurate models that have computationally burdensome implementations. We present a simple and accurate measurement matrix that is derived from the pseudo-spectral PAT model. The accuracy of the measurement matrix is first validated against the experimental PAT signal. We also compare the model against the standard k-wave measurement model and the spherical averaging model. We then highlight several reconstruction strategies based on the nature of the region of interest to further demonstrate the accuracy of the proposed measurement matrix.

An innovative WebRTC solution for e-Health services 为电子医疗服务提供创新的WebRTC解决方案
P. Pierleoni, Luca Pernini, Lorenzo Palma, Alberto Belli, Simone Valenti, Lorenzo Maurizi, Loris Sabbatini, A. Marroni
Solutions and services for e-Health and telemedicine are constantly spreading and becoming increasingly important in the health area thanks to last innovations in electronics, informatics and telecommunications. This work proposes an innovative service for the e-Health oriented to the maximum ease of use and to the sharing of vital signs. The proposal consists in a tele-counseling service based on the WebRTC technology that allows any person residing remotely from medical staff or hospital to directly interact with them. Our solution provides all the common functions of the WebRTC, such as real-time video and audio streams, instant messaging, and file sharing with the only requirement of a traditional web browser. Beyond that, we implemented the real-time transmission and visualization of vital signs and parameters acquired by biomedical sensors connected to the patient's personal device through the RTCDataChannel. Currently our solution involves the installation of a browser extension, but this operation is very simple and may be avoided when WebRTC APIs and browsers will support media streams coming from sensors at the same way as audio and video streams. Our solution demonstrates how web technologies can be applied in the health sector providing very effective services to patients and users which for various reasons have difficulties to travel to hospitals in order to have medical support.
由于电子、信息学和电信方面的最新创新,电子保健和远程医疗的解决方案和服务正在不断普及,并在卫生领域变得越来越重要。这项工作提出了一种面向最大易用性和生命体征共享的电子卫生创新服务。该提案包括基于WebRTC技术的远程咨询服务,允许任何远离医务人员或医院的人直接与他们互动。我们的解决方案提供了WebRTC的所有常用功能,例如实时视频和音频流,即时消息和文件共享,而只需要传统的web浏览器。除此之外,我们还实现了通过RTCDataChannel连接到患者个人设备的生物医学传感器获取的生命体征和参数的实时传输和可视化。目前我们的解决方案涉及安装浏览器扩展,但这个操作非常简单,当WebRTC api和浏览器将支持来自传感器的媒体流与音频和视频流相同的方式时,可以避免。我们的解决方案展示了如何将网络技术应用于卫生部门,为由于各种原因难以前往医院获得医疗支持的患者和用户提供非常有效的服务。
