Excessive exposure to solar ultraviolet (UV) radiation is the main cause of skin cancer. The dose-response between UV exposure and skin cancer occurrence is not yet fully understood since UV exposure is highly heterogeneous and strongly influenced by host and behavioural factors, such as posture, orientation to the sun, skin complexion and clothing. To address this issue, a three-dimensional (3D) numeric model (SimUVEx) has been developed to assess dose and distribution of anatomical UV exposure. The model uses 3D computer graphics techniques to compute UV radiance on the basis of postural information and ambient irradiation data, without necessitating time-consuming individual dosimetry, ensuring a wide potential use in skin cancer prevention and research. With the purpose to improve simulation capabilities in order to obtain more realistic scenarios and quantify effective sun protection strategies, a new version has been released, SimUVEX v2. Among new features, a specific morphology for the most sun-exposed body area, the head, has been added. We selected three different styles of hat (cap, wide-brimmed hat and helmet) to compare scenarios with and without solar protections considering the relative contribution of the direct, diffuse and reflected radiation. It was found that, sites directly covered apart (e.g., forehead and top of the head), hats with a wide brim are necessary in order to provide reasonable protections around facial zones on which non-melanoma skin cancers commonly occur, such as nose and cheeks.
过度暴露于太阳紫外线(UV)辐射是皮肤癌的主要原因。紫外线照射与皮肤癌发生之间的剂量反应尚未完全了解,因为紫外线照射是高度异质性的,并受到宿主和行为因素的强烈影响,如姿势、朝向太阳、皮肤肤色和衣服。为了解决这个问题,已经开发了一个三维(3D)数值模型(SimUVEx)来评估解剖紫外线照射的剂量和分布。该模型使用3D计算机图形技术,根据姿势信息和环境辐射数据计算紫外线辐射,而无需耗时的个人剂量测定,确保在皮肤癌预防和研究中的广泛潜在应用。为了提高模拟能力,以获得更真实的场景和量化有效的防晒策略,新版本SimUVEX v2已经发布。在新特征中,增加了最受阳光照射的身体区域的特定形态,即头部。我们选择了三种不同风格的帽子(软帽、宽檐帽和安全帽),考虑直接辐射、漫射辐射和反射辐射的相对贡献,比较了有和没有太阳防护的情况。研究发现,对于直接覆盖的部位(如前额和头顶),宽边帽子是必要的,以便在非黑色素瘤皮肤癌通常发生的面部区域(如鼻子和脸颊)周围提供合理的保护。

L. Sevrin, B. Massot, N. Noury, N. Abouchi, F. Jumel, Jacques Saraydaryan
As the world population gets older, the healthcare system must be adapted, among others by providing continuous health monitoring at home and in the city. The social activities have a significant role in everyone health status. Hence, this paper proposes a system to perform a data fusion of signals sampled on several subjects during social activities. This study implies the time synchronization of data coming from several sensors whether these are embedded on people or integrated in the environment. The data fusion is applied to several experiments including physical, cognitive and rest activities, with social aspects. The simultaneous and continuous analysis of four subjects cardiac activity and GPS coordinates provides a new way to distinguish different collaborative activities comparing the measurements between the subjects and along time.
随着世界人口的老龄化,医疗保健系统必须进行调整,其中包括在家庭和城市中提供持续的健康监测。社会活动对每个人的健康状况都有重要影响。因此,本文提出了一种对社会活动中多个主体采样的信号进行数据融合的系统。这项研究意味着来自多个传感器的数据的时间同步,无论这些传感器是嵌入在人身上还是集成在环境中。将数据融合应用于包括身体、认知和休息活动在内的几个实验中,并具有社会方面的意义。同时连续分析四名受试者的心脏活动和GPS坐标,通过比较受试者之间和时间的测量值,为区分不同的协同活动提供了一种新的方法。

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。

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。

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。

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.

Towards semantics in wearable sensors: The role of transducers electronic data sheets (TEDS) ontology in sensor networks 面向可穿戴传感器中的语义:传感器电子数据表(TEDS)本体在传感器网络中的作用
O. S. Ajigboye, K. Danas
Sensors, actuators and event sensors are the major types of transducers recognized by the IEEE 21451 standards for Smart Transducers. These contain information embedded in the Transducer Electronic Data Sheets (TEDS) that help describe the transducer and identify it in a network. Advancement in sensor and information technologies has led to various designs and development in wearable medical devices e.g. wireless Electrocardiogram (ECG) monitoring devices used to measure heart physiological parameters for diagnosis and monitoring of patients' health remotely. Most wearables were designed and proposed on IEEE 11073 standards, while, advances in implementation and application of smart transducers are based on ISO/IEC/IEEE 21451 standards. Therefore, seamless integration and interoperability between sensing technology in wearable and Health Information Systems (HIS) requires attention on the interoperability opportunities at the semantic level. The proposed ontology was implemented using Protege, SPARQL was used to evaluate it, and the performance analysis shows the greater description of the transducers with improve rate of recall and enhance interoperability at the semantic level.
传感器,执行器和事件传感器是IEEE 21451智能传感器标准认可的主要类型的传感器。这些包含嵌入在传感器电子数据表(TEDS)中的信息,这些信息有助于描述传感器并在网络中识别传感器。传感器和信息技术的进步导致了可穿戴医疗设备的各种设计和开发,例如用于测量心脏生理参数以远程诊断和监测患者健康的无线心电图(ECG)监测设备。大多数可穿戴设备是根据IEEE 11073标准设计和提出的,而智能传感器的实现和应用进展是基于ISO/IEC/IEEE 21451标准。因此,可穿戴传感技术与健康信息系统(HIS)之间的无缝集成和互操作性需要关注语义层面的互操作性机会。使用Protege实现了该本体,并使用SPARQL对其进行了评价,性能分析表明,该本体对换能器的描述更充分,召回率提高,语义层面的互操作性增强。

These contain information embedded in the Transducer Electronic Data Sheets (TEDS) that help describe the transducer and identify it in a network. Advancement in sensor and information technologies has led to various designs and development in wearable medical devices e.g. wireless Electrocardiogram (ECG) monitoring devices used to measure heart physiological parameters for diagnosis and monitoring of patients' health remotely. Most wearables were designed and proposed on IEEE 11073 standards, while, advances in implementation and application of smart transducers are based on ISO/IEC/IEEE 21451 standards.
