Deterministic clustering based compressive sensing scheme for fog supported heterogeneous wireless sensor networks
Venue: PeerJ Comput. Sci.
Year: 2021

Data acquisition problem in large scale distributed Wireless Sensor Networks (WSNs) is one of the main issues that hinder the evolution of Internet of Things (IoT) technology. Recently, combination of Compressive Sensing (CS) and routing protocols has attracted much attention. An open question in this approach is how to integrate these techniques effectively for specific tasks. In this paper, we introduce an effective deterministic clustering based CS scheme (DCCS) for fog supported heterogeneous WSNs to handle the data acquisition problem. DCCS employs the concept of fog computing, reduces total overhead and computational cost needed to self organize sensor network by using a simple approach, and then uses CS at each sensor node to minimize the overall energy expenditure and prolong the IoT network lifetime. Additionally, the proposed scheme includes an effective algorithm for CS reconstruction called Random Selection Matching Pursuit (RSMP) to enhance the recovery process at the base station (BS) side with a complete scenario using CS. RSMP adds random selection process during the forward step to give opportunity for more columns to be selected as an estimated solution in each iteration. The results of simulation prove that the proposed technique succeeds to minimize the overall network power expenditure, prolong the network lifetime and provide better performance in CS data reconstruction.
Learning Quadrupedal Locomotion over Challenging Terrain
Year: 2020

Some of the most challenging environments on our planet are accessible to quadrupedal animals but remain out of reach for autonomous machines. Legged locomotion can dramatically expand the operational domains of robotics. However, conventional controllers for legged locomotion are based on elaborate state machines that explicitly trigger the execution of motion primitives and reflexes. These designs have escalated in complexity while falling short of the generality and robustness of animal locomotion. Here we present a radically robust controller for legged locomotion in challenging natural environments. We present a novel solution to incorporating proprioceptive feedback in locomotion control and demonstrate remarkable zero shot generalization from simulation to natural environments. The controller is trained by reinforcement learning in simulation. It is based on a neural network that acts on a stream of proprioceptive signals. The trained controller has taken two generations of quadrupedal ANYmal robots to a variety of natural environments that are beyond the reach of prior published work in legged locomotion. The controller retains its robustness under conditions that have never been encountered during training: deformable terrain such as mud and snow, dynamic footholds such as rubble, and overground impediments such as thick vegetation and gushing water. The presented work opens new frontiers for robotics and indicates that radical robustness in natural environments can be achieved by training in much simpler domains.
The Comparison of Chinese and American Interpersonal Relationships
Year: 2013

In the course of globalization, the relationships between Chinese and American become closer and closer, and the communication between citizens of both countries is more and more frequent. However, because the culture of Chinese is much different from that of American, so do their attitude towards their family, friends, colleague and boss, and their principles and ways to deal with their interpersonal relationships. In order to make this kind of cross culture communication go on much more smoothly, it is necessary to explore and learn their differences of interpersonal relationships. Thus, this paper will make a comparison between Chinese and American interpersonal relationships from three aspects, they are the interpersonal relationships existed in family, friends, and working place, and analyze the reasons that contribute to these differences. Keywords interpersonal relationships; differences; cultural
Practical and secure integrated PKE+PEKS with keyword privacy
Venue: 2015 12th International Joint Conference on e Business and Telecommunications (ICETE)
Year: 2015

Public key encryption with keyword search (PEKS) schemes are useful to delegate searching capabilities on encrypted data to a third party, who does not hold the entire secret key, but only an appropriate token which allows searching operations but preserves data privacy. We propose an efficient and practical integrated public key encryption (PKE) and public key encryption with keyword search (PEKS) scheme (PKE+PEKS) which we prove to be secure in the strongest security notion for PKE+PEKS schemes. In particular, we provide a unified security proof of its joint CCA security in standard model. The security of our scheme relies on Symmetric eXternal Diffie Hellman (SXDH) assumption which is a much simpler and more standard hardness assumption than the ones used in most of the comparable schemes. Ours is the first construction to use asymmetric pairings which enable an extremely fast implementation useful for practical applications. Finally we compare our scheme with other proposed integrated PKE+PEKS schemes and provide a relative analysis of its efficiency.
Knowledge about Cervical Cancer and Pap Smear and the Factors Influencing the Pap test Screening among Women
Venue: International journal of community based nursing and midwifery
Year: 2017

Although the Pap smear is known as one of the effective methods to detect the cervical cancer, a large group of women are reluctant to do the test because of various reasons. Therefore, we carried out this study to determine the level of knowledge about cervical cancer and Pap smear and the factors influencing the Pap test screening among women.  In this cross sectional study, 355 women referred to the health centers of Gilan e gharb city were randomly recruited in 2015. The participants asked to complete a self administered questionnaire including five parts (questions about: demographic factors, knowledge about cervical cancer and Pap smear, Pap smear performance, barriers and facilitators related to Pap smear and the sources of information) Data were analyzed through SPSS version 19, using descriptive statistics, Independent T test, and logistic regression.  The mean age of the participants was 34.08+ 7.81 years. Almost 50.4% of the subjects had a history of Pap smear test. Pap test performance was significantly higher in those who had higher knowledge (P<0.001) Knowledge about cervical cancer, Pap smear and age was the most important predictors of the Pap test performance (P<0.001) The most important barrier and facilitator to Pap smear test were inadequate knowledge and the recommendations received from family, friends and healthcare professionals (44.3% and 40.2% respectively)  Knowledge about Pap smear and cervical cancer was important in predicting Pap test doing. In addition, inadequate knowledge was introduced as the most important barrier to screening test from the perspective of women. Therefore, we suggest that health education and health promotion studies as interdisciplinary and targeted interventions should be implemented to improve the women's knowledge.
A Study of Multiple Behavioral Addictions in a Substance Abuse Sample
Venue: Substance use misuse
Year: 2014

Behavioral addictions (BAs) are underrecognized, even in addiction programs. We assessed BAs in a substance abuse sample (n 51; data collection 2011 2012) A self report Behavioral Addictions Screen, assessing eight BAs, was administered using an automated telephone system. Most endorsed at least one BA, with the most common shopping/spending; eating; work; computer/internet; and sex/pornography. Lowest were gambling, self harm, and exercise. Some BAs were correlated with others. Gender, ethnicity, age, and positive depression and posttraumatic stress disorder screens were associated with specific BAs. Future research could address interpretation of "addiction," comparison to diagnostic interviews, relationship to substance use disorders, and larger samples.
Quality of Life of Implant Supported Overdenture and Conventional Complete Denture in Restoring the Edentulous Mandible: A Systematic Review
Venue: Implant dentistry
Year: 2017

The aim of this systematic review was to evaluate the oral health related quality of life (OHRQoL) associated with an implant supported overdenture (IOD) compared with a conventional complete denture (CCD) in restoring the edentulous mandible.  A literature search was performed in the MEDLINE (through Ovid) PubMed, and Cochrane Library databases for articles published between 1990 and July 2016. The search was restricted to articles published in English. Two reviewers selected the articles based on the inclusion and exclusion criteria. Another 2 reviewers analyzed the data.  From 108 articles that were obtained, 5 articles met the inclusion criteria. Four studies had a high risk of bias, and 1 study had an unclear risk of bias. There was a significant difference in Oral Health Impact Profile (OHIP) scores between pre and post treatment within the groups and in posttreatment OHIP scores between IOD and CCD groups.  Regarding the edentulous mandible, patients benefited more from the IOD with 2 implants, as determined by OHRQoL scores. Considering the differences between each domain of the Oral Health Impact Profile (OHIP) questionnaire and the lack of long term performance, more random control trials with sufficient sample sizes need to be designed to investigate long term performance after treatment.

Design and synthesis of mono and di pyrazolyl s triazine derivatives, their anticancer profile in human cancer cell lines, and in vivo toxicity in zebrafish embryos.
Venue: Bioorganic chemistry
Year: 2019

s Triazine is considered a privileged structure, as it is found in several FDA approved drugs. In the framework of our ongoing medicinal chemistry project based on the use of s triazine as a scaffold, we synthesized a series of mono and di pyrazolyl s triazine derivatives and tested them against four human cancer cell lines, namely Human breast carcinoma (MCF 7 and MDA MB 231) hepatocellular carcinoma (HepG2) colorectal carcinoma (LoVo) and leukemia (K562) The cell viability assay revealed that most of the s triazine compounds induced cytotoxicity in all four types of human cancer cell lines, however, compounds 4a, and 6g, both of them have a piperidine moiety in their structure were most effective. These two compounds affected the cell viability of cancer cells, with IC50 values within the range between 5 to 9 uM. The cell cycle analysis showed that 4a and 6g induced S and G2/M phase cell cycle arrest in K562 cells. This could be the mechanism by which these molecules induced cytotoxicity in tested cancer cells. The prepared compounds were tested in zebrafish embryos to evaluate in vivo and developmental toxicity of the pyrazolyl s triazine derivatives in animals. None of the derivatives were lethal in the concentration range tested.
Meaning Representation Parsing
Year: 2015

This project is aimed at solving the task 8 of SemEval 2016, in which, any English sentence had to be converted into its Abstract Meaning Representation (AMR) [ISI, 2015] All the data and the code for the baseline algorithm was provided by the organizer of the task. In the baseline algorithm provided for the same [Flanigan et al. 2014] we noticed that the AMR graph generation hugely depended on the focus of the sentence. And the baseline failed to recognize the focus quite often. So we used an LSTM to recognize the focus separately and use this new focus for generating the rest of the graph.  Meaning Representation (AMR) is a compact, readable, whole sentence semantic annotation. Annotation components include entity identification and typing, PropBank semantic roles, individual entities playing multiple roles, entity grounding via wikification, as well as treatments of modality, negation, etc."  AMR does not say anything about how it wants to be processed. 4. It is not an interlingua.  An ideal AMR graph for the sentence "The boy wants the girl to believe him."
2019 ESC Guidelines for the diagnosis and management of chronic coronary syndromes.
Venue: European heart journal
Year: 2019

Coronary artery disease (CAD) is a pathological process characterized by atherosclerotic plaque accumulation in the epicardial arteries, whether obstructive or non obstructive. This process can be modified by lifestyle adjustments, pharmacological therapies, and invasive interventions designed to achieve disease stabilization or regression. The disease can have long, stable periods but can also become unstable at any time, typically due to an acute atherothrombotic event caused by plaque rupture or erosion. However, the disease is chronic, most often progressive, and hence serious, even in clinically apparently silent periods. The dynamic nature of the CAD process results in various clinical presentations, which can be conveniently categorized as either acute coronary syndromes (ACS) or chronic coronary syndromes (CCS) The Guidelines presented here refer to the management of patients with CCS. The natural history of CCS is illustrated in
Corporate governance: five factor theory based financial fraud identification
Year: 2020

The frequent occurrences of financial fraud in listed companies have had a serious impact on the stable development of the capital market. The Chinese company, Luckin Coffee, listed in the USA, recently confessed to fabricating transactions worth RMB2.2 billion and has received a delisting notice from NASDAQ. It can be seen that the detection and analysis of financial fraud behavior is very important not only for the internal governance of companies and for their external investors but also for regulatory agencies. This article uses a research method combining normative analysis with empirical research, utilizes a targeted selection of data from the listed companies penalized due to fictitious profits, uses the CRIME theory as the basis for normative analysis, and establishes a financial fraud identification model by means of empirical analysis. Finally, based on the research results of this article, we propose rational governance measures for countering the problems of fraud in financial statements of listed companies.
Effect of User Mobility and Channel Fading on the Outage Performance of UAV Communications
Venue: IEEE Wireless Communications Letters
Year: 2020

Many wireless networks operate in a mobile environment with randomly moving user terminals. This letter analytically characterizes the impact of ground user mobility, propagation environment and channel fading on the outage performance of unmanned aerial vehicle (UAV) communications. Closed form expressions for the outage probability using the random waypoint model for ground user mobility, UAV channel models for different propagation environments and the Nakagami {m} model for fading channels are derived. Furthermore, the outage analysis takes into account the effect of co channel interference by both the stationary and mobile users. Numerical results are presented to demonstrate the interplay between the communication performance and the system parameters.

The findings revealed that the Genetics and DNA technology unit on the STS approach are promoted students' critical thinking and problem solving ability. Not only indicated that the solution raised from the problem that lead to solving through critical thinking and problem solving but also could be mentioned that students developed their ability of critical thinking and problem solving while they learned STS of GMO issue. These finding would be a good practices for teaching biology through STS approach to who may take further applications for science teaching and learning
Associations of job strain and lifestyle risk factors with risk of coronary artery disease: a meta analysis of individual participant data
Venue: Canadian Medical Association Journal
Year: 2013

It is unclear whether a healthy lifestyle mitigates the adverse effects of job strain on coronary artery disease. We examined the associations of job strain and lifestyle risk factors with the risk of coronary artery disease.  We pooled individual level data from 7 cohort studies comprising 102 128 men and women who were free of existing coronary artery disease at baseline (1985 2000) Questionnaires were used to measure job strain (yes v. no) and 4 lifestyle risk factors: current smoking, physical inactivity, heavy drinking and obesity. We grouped participants into 3 lifestyle categories: healthy (no lifestyle risk factors) moderately unhealthy (1 risk factor) and unhealthy (2 4 risk factors) The primary outcome was incident coronary artery disease (defined as first nonfatal myocardial infarction or cardiac related death)  There were 1086 incident events in 743 948 person years at risk during a mean follow up of 7.3 years. The risk of coronary artery disease among people who had an unhealthy lifestyle compared with those who had a healthy lifestyle (hazard ratio [HR] 2.55, 95% confidence interval [CI] 2.18 2.98; population attributable risk 26.4% was higher than the risk among participants who had job strain compared with those who had no job strain (HR 1.25, 95% CI 1.06 1.47; population attributable risk 3.8% The 10 year incidence of coronary artery disease among participants with job strain and a healthy lifestyle (14.7 per 1000) was 53% lower than the incidence among those with job strain and an unhealthy lifestyle (31.2 per 1000)  The risk of coronary artery disease was highest among participants who reported job strain and an unhealthy lifestyle; those with job strain and a healthy lifestyle had half the rate of disease. A healthy lifestyle may substantially reduce disease risk among people with job strain.
Recurrent Neural Networks for Environmental Sound Recognition using Scikit learn and Tensorflow
Venue: 2019 16th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI CON)
Year: 2019

In this paper, we perform comparison techniques for environmental sound classification with multilayer perceptron (MLP) and support vector machine (SVM) and deep learning using new machine learning platforms, i.e. Scikit learn and Tensorflow, respectively. For feature based classification, principal component analysis of short time Fourier transform is used as our feature as the front end to MLP and SVM. For deep learning based classification, convolution+pooling layers is acting as feature extractor from the input image, while fully connected layer will act as a classifier. Our experimental results show that our proposed deep neural network (DNN) models outperform the feature based sound classification algorithms and the original deep learning work
Analisis CFD Hambatan Kapal Katamaran dengan Stepped Hull Melintang
Year: 2021

Perkembangan dalam ilmu dan teknologi telah memajukan metode dan pengetahuan dari desain lambung kapal. Kapal cepat memerlukan bentuk lambung yang baik untuk beroperasi secara efisien dan salah satu cara untuk mencapai efisiensi yang baik adalah dengan menggunakan step pada lambung kapal. Step pada lambung adalah diskontinuitas tajam yang berlokasi pada permukaan alas dari lambung. Pada kondisi sekarang, desain dari kapal dengan stepped hull hanya dilakukan pada kapal planing monohull, namun pengembangan desain untuk kapal katamaran dengan stepped hull sudah mulai dilakukan oleh para desainer kapal. Diketahui bahwa analisa hambatan pada lambung katamaran dengan transverse stepped hull masih sangat terbatas di dalam literatur. Penelitian ini bertujuan untuk memahami efek penggunaan step pada lambung katamaran terhadap hambatan kapal. Analisis hambatan pada penelitian ini menggunakan simulasi dengan Computational Fluid Dynamics (CFD) Dalam simulasi tersebut, dianalisa pengaruh step pada hambatan kapal pada konfigurasi monohull dan katamaran menggunakan lambung tipe round bilge. Model katamaran diuji dengan separation ratio (S/L) 0,3. Variasi kecepatan pada setiap model dilakukan pada Froude Number 0,2, 0,3, 0,4, 0,5, 0,6, dan 0,7. Validasi dilakukan dengan menggunakan hasil uji tarik yang telah dilakukan untuk model tanpa stepped hull. Dari hasil simulasi diperoleh nilai hambatan, permukaan basah, tekanan pada model, dan wave pattern yang dihasilkan. Dari hasil simulasi didapatkan bahwa hasil simulasi CFD mendapatkan hasil dengan keselarasan yang baik dengan hasil eksperimen dengan margin perbedaan sesuai dengan kriteria yaitu di bawah 5% Hasil perbandingan antara model dengan dan tanpa stepped hull mendapatkan hasil pada model monohull dengan stepped hull terjadi pengurangan nilai CT dan RT/D pada Fr 0,2 0,3 dan penambahan nilai tersebut pada Fr 0,4 0,7. Pada model katamaran dengan stepped hull terjadi pengurangan nilai CT pada Fr 0,2, dan penambahan nilai CT pada Fr 0,3 0,7 dan RT/D pada Fr 0,2 0,7.
