UAV-supported intelligent truth discovery to achieve low-cost communications in mobile crowd sensing

Unmanned and aerial systems as interactors among different system components for communications,have opened up great opportunities for truth data discovery in Mobile Crowd Sensing(MCS)which has not been properly solved in the literature.In this paper,an Unmanned Aerial Vehicles-supported Intelligent Truth Discovery(UAV-ITD)scheme is proposed to obtain truth data at low-cost communications for MCS.The main innovations of the UAV-ITD scheme are as follows:(1)UAV-ITD scheme takes the first step in employing UAV joint Deep Matrix Factorization(DMF)to discover truth data based on the trust mechanism for an Information Elicitation Without Verification(IEWV)problem in MCS.(2)This paper introduces a truth data discovery scheme for the first time that only needs to collect a part of n data samples to infer the data of the entire network with high accuracy,which saves more communication costs than most previous data collection schemes,where they collect n or kn data samples.Finally,we conducted extensive experiments to evaluate the UAV-ITD scheme.The results show that compared with previous schemes,our scheme can reduce estimated truth error by 52.25%–96.09%,increase the accuracy of workers’trust evaluation by 0.68–61.82 times,and save recruitment costs by 24.08%–54.15%in truth data discovery.

Truth telling for patients with esophageal squamous cell carcinoma in Henan,China

Objective: This study aims to investigate the truth-telling status and the relevant factors of esophageal squamous cell carcinoma(ESCC) patients in Henan, China.Methods: A cross-sectional study from April to June 2015 using questionnaires was given to 301 family members of hospitalized ESCC patients based in three affiliated hospitals of Zhengzhou University(i.e., The First Hospital, The Second Hospital, and Tumor Hospital) and Anyang Tumor Hospital.Results: Among the 41.9%(126/301) hospitalized ESCC patients who knew of their true diagnoses, only 4.0% patients were informed by their corresponding responsible doctors, 39.7% by their family members, and 56.3% by themselves. Univariate analyses showed that disclosure of confirmed ESCC diagnosis to patients was correlated with gender, family history of cancer(FHC), education level, vocation, hospital administrative level, and attitudes of family members(P < 0.05). Furthermore,multivariate analysis indicated that attitude of family members was the most important and an independent factor for diagnosis disclosure. Those patients with a negative FHC, under-education, manual occupation, advanced stages, and hospitalized in municipal hospitals exhibited a low rate of truth telling.Conclusions: Truth telling for ESCC patients in Henan is not prevalent and may be improved through consultation with family members, particularly for patients with a negative FHC, poor education, manual occupation, and advanced stages.

Classification of Sailboat Tell Tail Based on Deep Learning

The tell tail is usually placed on the triangular sail to display the running state of the air flow on the sail surface.It is of great significance to make accurate judgement on the drift of the tell tail of the sailboat during sailing for the best sailing effect.Normally it is difficult for sailors to keep an eye for a long time on the tell sail for accurate judging its changes,affected by strong sunlight and visual fatigue.In this case,we adopt computer vision technology in hope of helping the sailors judge the changes of the tell tail in ease with ease.This paper proposes for the first time a method to classify sailboat tell tails based on deep learning and an expert guidance system,supported by a sailboat tell tail classification data set on the expert guidance system of interpreting the tell tails states in different sea wind conditions,including the feature extraction performance.Considering the expression capabilities that vary with the computational features in different visual tasks,the paper focuses on five tell tail computing features,which are recoded by an automatic encoder and classified by a SVM classifier.All experimental samples were randomly divided into five groups,and four groups were selected from each group as the training set to train the classifier.The remaining one group was used as the test set for testing.The highest resolution value of the ResNet network was 80.26%.To achieve better operational results on the basis of deep computing features obtained through the ResNet network in the experiments.The method can be used to assist the sailors in making better judgement about the tell tail changes during sailing.

Process of Patients Telling Children about Newly Diagnosed Breast Cancer

Objective: This study aims to determine the process of patients with newly diagnosed breast cancer in Japan telling their children about the disease, and how they have thought about it after the diagnosis. Methods: Semi-structured interviews were conducted with 15 patients with newly diagnosed breast cancer who had 3- to 14-year-old children. Narratives of participants about how they told their children about the disease were analysed by a qualitative and descriptive study design using the Modified Grounded Theory Approach (M-GTA). Results: In the process by which patients with newly diagnosed breast cancer tell their children about the disease, participants were [Maintaining mental balance in the face of the threat of the cancer] after the breast cancer diagnosis, and used the “Facing the cancer through the relationship with the children” as the core category in the process. The participants had [Determined to tell the children about the disease], while [Being worried about the influence of cancer on the children], [Thinking about the benefits of not hiding the cancer], and [Feeling difficulty in communicating the diagnosis of cancer to their children]. They were [Encouraged to tell about the disease to the children] by people around them, and did tell the children that they had a “disease” or “cancer”. The participants who told the children that they had the disease while [Determining the impact on the children] repeated the [Making herself look unconcerned] in the process. Those who told the children that they had cancer while [Determining the impact on the children] repeated [Talking openly about cancer and death] between parents and children. Conclusions: The participants came to face their own cancer by maintaining mental balance in the face of the threat of the cancer and telling their children about the disease. Nurses need to assist these patients to be able to deal openly with their children from the early stage of the diagnosis and solve problems by family members.

Lightweight privacy-preserving truth discovery for vehicular air quality monitoring

Air pollution has become a global concern for many years.Vehicular crowdsensing systems make it possible to monitor air quality at a fine granularity.To better utilize the sensory data with varying credibility,truth discovery frameworks are introduced.However,in urban cities,there is a significant difference in traffic volumes of streets or blocks,which leads to a data sparsity problem for truth discovery.Protecting the privacy of participant vehicles is also a crucial task.We first present a data masking-based privacy-preserving truth discovery framework,which incorporates spatial and temporal correlations to solve the sparsity problem.To further improve the truth discovery performance of the presented framework,an enhanced version is proposed with anonymous communication and data perturbation.Both frameworks are more lightweight than the existing cryptography-based methods.We also evaluate the work with simulations and fully discuss the performance and possible extensions.

The History of the Concept of“Truth-Making”

The conception of truth-making,albeit in a rudimentary form,could already be discerned in the writings of G.E.Moore and E.Husserl in the early 1900s.A few years later it was more extensively exploited by William James.It was Wittgenstein,however,who gave the concept a precise meaning.In 1913/1914 Wittgenstein advanced a theory of possible worlds,only one of which was real.Every proposition suggests a part of a possible world which does or does not correspond to parts of the real world.In the first case the proposition is true,in the second case false.Moreover,the part of the real world makes the sentence true.This part is a truth-maker,and the sentence is a truth-bearer.Surprisingly enough,Wittgenstein’s concept of truth-making had its family resemblance with William James’s conception of truth.In 1915 Wittgenstein stopped using the concept of truth-making-it was also not mentioned in the Tractatus.Unfortunately,Russell did not notice this and in 1918 he adopted the concept of truth-making.In the 1930s,it was used by some second generation analytic philosophers(Schlick,Stebbing,and Wisdom).However,it became rather popular among analytic philosophers only in the 1980s.

融合IMR-WGAN的时序数据修复方法

工业数据由于技术故障和人为因素通常导致数据异常,现有基于约束的方法因约束阈值设置的过于宽松或严格会导致修复错误,基于统计的方法因平滑修复机制导致对时间步长较远的异常值修复准确度较低.针对上述问题,提出了基于奖励机制的最小迭代修复和改进WGAN混合模型的时序数据修复方法.首先,在预处理阶段,保留异常数据,进行信息标注等处理,从而充分挖掘异常值与真实值之间的特征约束.其次,在噪声模块提出了近邻参数裁剪规则,用于修正最小迭代修复公式生成的噪声向量.将其传递至模拟分布模块的生成器中,同时设计了一个动态时间注意力网络层,用于提取时序特征权重并与门控循环单元串联组合捕捉不同步长的特征依赖,并引入递归多步预测原理共同提升模型的表达能力;在判别器中设计了Abnormal and Truth奖励机制和Weighted Mean Square Error损失函数共同反向优化生成器修复数据的细节和质量.最后,在公开数据集和真实数据集上的实验结果表明,该方法的修复准确度与模型稳定性显著优于现有方法.

论日常新闻的实质特征与功能意义

日常新闻指的是以普通民众为生产主体、面向个体日常生活领域,并在普通民众日常交往中生产和传播的新闻。日常新闻的对象事实来自人们的日常生活领域,关注的是普通民众的衣食住行、社区邻里之间的逸闻趣事,以及熟人圈层中的礼尚往来等。普通民众参与日常新闻生产、传播和消费的过程也是私人交往秩序的建构过程,因此,日常新闻的实质是普通民众在日常生活实践中的一种私人交往。日常新闻总体的也是核心的特征是日常性,这既体现在日常新闻的事实来源与内容面向,也体现在其生产传播与交往交流的方式。日常新闻的社会功能主要体现在普通民众的日常生活与日常交往之中。日常新闻既是普通民众延展主体性的重要形式,也是普通民众维系日常交往的基本方式,还是社会日常文化经验传播(交流)、传承的重要方式。日常新闻交往反映着普通民众真实的生活状态与多元化交往样态,对主体在日常生活实践中的身份建构、日常交往关系的建构以及日常生活世界的真相建构都具有不可替代的作用和意义。
