Exploiting User Friendship Networks for User Identification across Social Networks

Identifying offline entities corresponding to multiple virtual accounts of users across social networks is crucial for the development of related fields, such as user recommendation system, network security, and user behavior pattern analysis. The data generated by users on multiple social networks has similarities. Thus, the concept of symmetry can be used to analyze user-generated information for user identification. In this paper, we propose a friendship networks-based user identification across social networks algorithm (FNUI), which performs the similarity of multi-hop neighbor nodes of a user to characterize the information redundancy in the friend networks fully. Subsequently, a gradient descent algorithm is used to optimize the contribution of the user’s multi-hop nodes in the user identification process. Ultimately, user identification is achieved in conjunction with the Gale–Shapley matching algorithm. Experimental results show that compared with baselines, such as friend relationship-based user identification (FRUI) and friendship learning-based user identification (FBI): (1) The contribution of single-hop neighbor nodes in the user identification process is higher than other multi-hop neighbor nodes; (2) The redundancy of information contained in multi-hop neighbor nodes has a more significant impact on user identification; (3) The precision rate, recall rate, comprehensive evaluation index (F1), and area under curve (AUC) of user identification have been improved.

APPLICATION OF INTERNET OF THINGS BASED ROOM SECURITY SYSTEM USING ANDROID APPLICATION

Along with the increasing crime rate of data theft that occurs, it takes a good room security system to maintain data security for a particular agency or organization. Something A good security system is a security system that can be monitored and controlled remotely using the internet or better known as IoT (Internet of Things). In this thesis will designed an IoT-based room security system using the Android application, this system works using several modules including RFID (Radio Frequency Identification) module, camera module and door lock solenoid. The RFID card in this RFID Module functions as an identification process for people who want to enter into the room. In addition, this RFID module also functions as a trigger for the camera to work to take pictures a picture of the person who wants to enter the room. The data obtained from the two modules later will be sent into the Android application. The admin of the room can carry out the verification process to allow or deny people who want to enter the room. The results of testing this system can be runs well when the internet speed of the access point is fast and stable, but less optimal when the internet speed of the access point is running slowly.

OBJECTIVES: The objective of the study was to assess the diversity of mosquitoes in various towns of the southern belt of KPK. METHODOLOGY: This was a descriptive study that was conducted in numerous towns of Western belt of Khyber Pakhtunkhwa. The study areas were Darra Adam Khel, District Kohat, District Karak, District Banu, District D.I. Khan and newly merged districts Mir Ali and Miranshah. From each study site, the samples were collected randomly. The sample collection was done through survey and area visits whereas; the identification process was done in a parasitology laboratory of Hayatabad-Peshawar. Sampling was done from June 2016 to May 2017. RESULTS: A total of 2150 adult mosquitoes were gathered and collected from 42 different locations of the southern belt of KPK and were identified. Based on their identification, 5 genera of the mosquitoes were recognized which were Culex, Anopheles, Psorophora, Aedes and Uranotenia. Culex was found to be most dominant in all the visited areas with a percentage of 12.65 in Miranshah followed by 11.81 in Mirali, 7.16 in Karak, 6.88 in Darra Adam Khel, 6.69 in D.I.Khan, 6.41 in Kohat and 5.11 in Bannu respectively. The results of our findings also revealed the presence of Culex genera in all the habitats and remained the dominant genera among the others followed by Anopheles and Psorophora. Aedes was found in the habitat of plants and grasses etc. whereas Uranotenia was found in marsh/swampy areas as well as in plants/grasses habitat only. CONCLUSION: The outcomes reveal that a climate shifting and extensive urbanization process is enforcing the diversity of mosquitos’ fauna in the southern belt of KPK.

Edukasi Pengenalan Huruf Hijaiyah dengan Memanfaatkan Teknologi Augmented Reality

Augmented Reality (AR) technology provides opportunities for science and engineering. AR also has great opportunities in the world of education, which is to provide and display additional information in the form of 3D objects, video, sound, and text on an object. Smartphone software developers have developed Augmented reality technology that was previously developed on PC devices where this technology utilizes the existing camera on a smartphone. With this situation, AR technology has the opportunity to be used in the development of a media for recognizing hijaiyah letters, so that children will be happier learning because of its attractive appearance and teachers or parents can more easily teach lessons to their children. The way to use it is as follows: first, the user puts a registered and printed marker, second, the smartphone camera identifies (tracking) the marker. If the marker is invalid, the user repeats the identification process. If the marker is valid and identified, the marker will display the hijaiyah letter object in three-dimensional form. Third, users can understand the shape and pronunciation of hijaiyah letters by touching the virtual button on the marker

In vitro Metabolic Stability of Drugs and Applications of LC-MS in Metabolite Profiling

Metabolic stability of a compound is an important factor to be considered during the early stages of drug discovery. If the compound has poor metabolic stability, it never becomes a drug even though it has promising pharmacological characteristics. For example, a drug is quickly metabolized in the body; it does not have sufficient in vivo exposure levels and leads to the production of toxic, non-active or active metabolites. A drug is slowly metabolized in the body it could remain longer periods in the body and lead to unwanted adverse reactions, toxicity or may cause drug interactions. Metabolic stability assay is performed to understand the susceptibility of the compound to undergo biotransformation in the body. Intrinsic clearance of the compound is measured by metabolic stability assays. Different in vitro test systems including liver microsomes, hepatocytes, S9 fractions, cytosol, recombinant expressed enzymes, and cell lines are used to investigate the metabolic stability of drugs. Metabolite profiling is a vital part of the drug discovery process and LC–MS plays a vital role. The development of high-resolution (HR) MS technologies with improved mass accuracy, in conjunction with novel data processing techniques, has significantly improved the metabolite detection and identification process. HR-MS based data acquisition (ion intensity-dependent acquisition, accurate-mass inclusion list-dependent acquisition, isotope pattern-dependent acquisition, pseudo neutral loss-dependent acquisition, and mass defect-dependent acquisition) and data mining techniques (extracted ion chromatogram, product ion filter, mass defect filter, isotope pattern filter, neutral loss filter, background subtraction, and control sample comparison) facilitate the drug metabolite identification process.

THE APPLICATION OF CELL-FREE FETAL DNA (cff-DNA) AND SIBLINGS DNA METHODS IN THE PROCESS OF PATERNITY TEST THROUGH CODIS STR LOCI (CSF1PO, THO1, TPOX, AND vWA)

Background: The non-invasive cff-DNA and siblings DNA methods are the latest breakthroughs in the forensic identification process. The use of cff-DNA and siblings DNA as non-invasive techniques in the forensic identification process has, hitherto, not been widely proven. Methods and Materials: This was an analytic observational study. The sample of this study consisted of peripheral blood of women in the second trimester of pregnancy and their two biological children. The kinship analysis was carried out through siblings' DNA and cff-DNA from the mothers through CODIS STR loci (CSF1PO, THO1, TPOX, and vWA). Results: The means of allele sharing between full siblings in loci CSF1PO, THO1, TPOX, and vWA were 0 (13.75%), 1 (44.75%), and 2 (41.50%). The allele sharing found in the study is in line with the one in previous research conducted by Wenk (1998) and the theory proposed by O'Connor (2011), indicating that one allele sharing dominates, contrasting with the finding of previous research conducted by Sosiawan (2020) revealing that 2-allele sharing was more superior. The variation is caused by the ethnicity having a different genetic contribution among the population. The variation can be attributed to historical and demographical processes leading to genetic drift. Conclusion: The mean of SI in 1 allele sharing in CODIS STR loci (CSF1PO, THO1, TPOX, and vWA) has the highest value of 44.5%. The use of cff-DNA of pregnant women as one of the non-invasive techniques can serve as an alternative material in a paternity test.
