Privacy-Aware Adversarial Network in Human Mobility Prediction

As mobile devices and location-based services are increasingly developed in different smart city scenarios and applications, many unexpected privacy leakages have arisen due to geolocated data collection and sharing. User re-identification and other sensitive inferences are major privacy threats when geolocated data are shared with cloud-assisted applications. Significantly, four spatio-temporal points are enough to uniquely identify 95\% of the individuals, which exacerbates personal information leakages. To tackle malicious purposes such as user re-identification, we propose an LSTM-based adversarial mechanism with representation learning to attain a privacy-preserving feature representation of the original geolocated data (i.e., mobility data) for a sharing purpose. These representations aim to maximally reduce the chance of user re-identification and full data reconstruction with a minimal utility budget (i.e., loss). We train the mechanism by quantifying privacy-utility trade-off of mobility datasets in terms of trajectory reconstruction risk, user re-identification risk, and mobility predictability. We report an exploratory analysis that enables the user to assess this trade-off with a specific loss function and its weight parameters. The extensive comparison results on four representative mobility datasets demonstrate the superiority of our proposed architecture in mobility privacy protection and the efficiency of the proposed privacy-preserving features extractor. We show that the privacy of mobility traces attains decent protection at the cost of marginal mobility utility. Our results also show that by exploring the Pareto optimal setting, we can simultaneously increase both privacy (45%) and utility (32%)

Content dissemination in participatory delay tolerant networks

As experience with the Web 2.0 has demonstrated, users have evolved from being only consumers of digital content to producers. Powerful handheld devices have further pushed this trend, enabling users to consume rich media (for example, through high resolution displays), as well as create it on the go by means of peripherals such as built-in cameras. As a result, there is an enormous amount of user-generated content, most of which is relevant only within local communities. For example, students advertising events taking place around campus. For such scenarios, where producers and consumers of content belong to the same local community, networks spontaneously formed on top of colocated user devices can offer a valid platform for sharing and disseminating content. Recently, there has been much research in the field of content dissemination in mobile networks, most of which exploits user mobility prediction in order to deliver messages from the producer to the consumer, via spontaneously formed Delay Tolerant Networks (DTNs). Common to most protocols is the assumption that users are willing to participate in the content distribution network; however, because of the energy restrictions of handheld devices, users’ participation cannot be taken for granted. In this thesis, we design content dissemination protocols that leverage information about user mobility, as well as interest, in order to deliver content, while avoiding overwhelming noninterested users. We explicitly reason about battery consumption of mobile devices to model participation, and achieve fairness in terms of workload distribution. We introduce a dynamic priority scheduling framework, which enables the network to allocate the scarce energy resources available to support the delivery of the most desired messages. We evaluate this work extensively by means of simulation on a variety of real mobility traces and social networks, and draw a comparative evaluation with the major related works in the field

Research study in cancer by gender, age groups, and kinds of cancer

Background: Cancer is a malignant disease with high incidence in both genders and all age groups. The prevalence of these serious types of cancer which also vary according to age groups and kinds of cancer must be known. Studies are a must to get more attention to these diseases and occasions for prevention of widespread occurrence. Objective: This study was done to study the estimated cancer incidence by gender, age groups, and kinds of cancer in patients. Materials and Methods: 200 cases of cancer patients that were admitted in oncology wards of the hospital after diagnosis with cancer and getting surgery, chemotherapy and radiology in Iran, Zahedan city region, were studied. The study lasted from 12th April 2014 to 20th March 2015. Data collection was during 12 months by follow-up of patients. Collected data of gender, age groups, and kinds of cancer were assessed with frequency statistics test. Results: In particular, females of 35-39 and 50-54 age groups were more vulnerable, and Leukemia was the most frequent type of cancer in the affected population. Cancer research by gender and age groups shows female in 40-44 and male in 35-39 age groups were in high-risk groups. Furthermore, cancer by gender and kinds of cancer indicate that females suffer from leukemia more than males; in contrast, males are affected by lymphoma with higher rate than females. Conclusions: Findings in this study revealed different results in gender, variety of age groups, and kinds of cancer. We studied some important factors to assess high-risk groups in every region of world. This finding gives useful information to reduce high susceptibility risk by positive lifestyle choices, not smoking, eating a healthy diet, being physically active, and improving health education

The Study of Structural Practice Approach vs. Awareness-Raising Approach in Teaching Verb Tenses to EFL Students

ABSTRACT This study intends to investigate the differences between two approaches to teaching English verb tenses to EFL learners, i.e., the formal instruction of structural pattern drills and the other is grammar task performance through 'awareness-raising approach'. The participants in this study include 50 university students majored in English who were randomly selected from Islamic Azad University of Behbahan. To carry out the study, two kinds of teaching materials were utilized, i.e., the 'awareness-raising' tasks on verb tenses selected from "Grammar in action again" textbook and the 'structurally-based' lessons and activities on English verb tenses taken from "Communicate what you mean" textbook. Analyzing the data, the researchers came to the conclusion that in teaching English verb tenses to intermediate learners, awareness raising approach could lead to a better and more efficient contribution to learning verb tense aspects. The statistical analysis of subjects' performances also proved that recent communicative approaches like awareness rising or consciousness rising, which use authentic and meaningful materials, are more favored by language learners. The implications of this study are considered in foreign language learning programs as well as material developing and text-book writing

Compositional homogeneity in a medical-grade stainless steel sintered with a Mn-Si additive

Cataloged from PDF version of article.In this paper, chemical composition uniformity in amorphous/nanocrystallization medical-grade stainless steel (ASTM ID: F2581) sintered with a Mn–Si additive was studied via scanning electron microscopy, energy dispersive X-ray spectroscopy, and transmission electron microscopy. The results show that as a result of sintering at 1000 °C, no dissociation of Mn–Si additive particles embedded in the stainless steel matrix occurs. In contrast, sintering at 1050 °C develops a relatively homogeneous microstructure from the chemical composition viewpoint. The aforementioned phenomena are explained by liquation of the Mn–Si eutectic additive, thereby wetting of the main powder particles, penetrating into the particle contacts and pore zones via capillary forces, and providing a path of high diffusivity. © 2012 Elsevier B.V.

Liquid-phase sintering of medical-grade P558 stainless steel using a new biocompatible eutectic additive

Cataloged from PDF version of article.One of the effective approaches to reduce residual pores in powder metallurgy parts is activated liquidphase sintering process using proper additives. In this work, for the first time, a new biocompatible additive (Mn–11.5 wt.% Si, a eutectic alloy) is experimented for liquid-phase sintering of nanocrystalline/amorphous P558 stainless steel powders. It is realized that by increasing the sintering aid content and temperature, the density is effectively increased: a sharp densification progress when the sintering temperature increases from 1000 °C to 1050 °C and a slower densification rate when it exceeds 1050 °C. This preliminary study opens up the development of high-density medical-grade stainless steels produced by powder metallurgy, where suitable additives can lower sintering temperature and time, which is promising for retarding grain growth and commercial applications. © 2012 Elsevier B.V.
