This study conducted through a cross-sectional survey on the students' perceptions about their use of social networking sites and their influence on their academic performance. The researcher gathered data from the students of Gomal and Quratba University in D.I.Khan and used the Statistical Package for Social Sciences (SPSS) (Pearson's correlation coefficient test) to analyze the data and infer findings and draw a conclusion. The study found that computer-mediated communication through social media sites, the GPA of male students is more affected than those of female students and H1 of the study accepted. And it is also found that H2 of the study that social media use in 2nd semester and their GPA of age group 20 and less than 25, that there is a significant relationship between the GPA and 2nd-semester use of SNS as indicated.

Gesture-based interaction is one of the prominent fields of natural interactions. The recognition and application of hand gestures in virtual environments (VEs) need extensive calculations due to the complexities involved, which directly affect the performance and realism of interaction. In this paper, we propose a new interaction technique that uses single fingertip-based gestures for interaction with VEs. The objective of the study is to minimize the computational cost, increase performance, and improve usability. The interaction involves navigation, selection, translation, and release of objects. For this purpose, we propose a low-cost camera-based system that uses a colored fingertip for the fastest and accurate recognition of gestures. We also implemented the proposed interaction technique using the Leap Motion controller. We present a comparative analysis of ...

The disease is often witnessed in patients with leukemia; however, a few cases of ecthyma gangrenosum in adults were reported to be associated with myelofibrosis. We report a case of ecthyma gangrenosum due to Escherichia coli (E. coli) in a two-year-old girl with idiopathic myelofibrosis.

Depending on the purpose of the collaborative work, techniques of interaction and manipulation change from one application to another. There is no general, good and efficient solution for all the collaborative systems. In addition, people in CVEs also use communication channels to share task goals, task decomposition and task progress. Therefore, awareness and communication are usually considered as important instruments to complete collaborative task. In this paper we present a comparative study of user performance with assembly task across four different guidance navigation aids i.e. 3-Dimensional Map-Liner (3DML), Audio, Textual and Arrows-Casting. Dijkstra's algorithm is used for shortest path selection while making the assembly task in CVEs. We conducted experiments on different college students to check the performance of the students. We reported the results of a precise experiments containing of 24 virtual teams of 48 individual students. Overall results showed that students performed task faster using the arrows while they were slow with audio support in navigation.

ARToolKit, an open-source computer tracking library for the creation of augmented reality applications that overlay virtual imagery on the real world, is such a system. It uses a simple camera and black-and-white markers printed on paper. However, due to inter-marker confusion, if the marker distinctions are not ensured, the markers are often miss-recognized. This paper presents an ARToolKit-based Interactive Writing Board (IWB) with a simple mechanism for designing confusion-free marker libraries. The board is used for teaching single characters of Arabic/Urdu to primary level students. It uses a simple ARToolKit marker for the recognition of each character. After marker recognition, the IWB displays the corresponding image, helping students with character understanding and pronunciation. Experimental results reveal that the system improves students’ motivation and learning skills.

Over the years, many studies have been conducted to find predictors of coronary artery disease; however, in the last few decades, the level of HbA1c in diabetics has been investigated as a potential predictor. Our study offers additional insight by investigating similar relationships in nondiabetic patients and by investigating potential predictors more comprehensively, making it the first of its kind study. The aim of our study is to indicate that rising HbA1c levels suggest that there's a greater risk of coronary artery disease, which can further be confirmed by the SYNTAX score, degree of stenosis, and numbers of vessels involved. Methods Data from 177 diabetic and 378 non-diabetic patients, all of whom were above 18 years of age, were included in the research. HbA1c levels (>5.6%), SYNTAX score, hypertension, number of vessels involved, and other demographic elements, such as age, smoking, and body measurements, were calculated and compared for diabetics and non-diabetics. Results HbA1c was higher in comparison to non-diabetic subjects (p <0.001). Age >53 was found to be a predictor for SYNTAX score ≥23 in diabetic patients (p <0.05). Male gender and smoking were found to be independent predictors for three-vessel disease in the non-diabetic population (p-value<0.05). There was no significant relationship between the SYNTAX score and HbA1c levels in non-diabetics (p=0.885) and diabetics. In conclusion, there is no correlation between elevated HbA1c levels and SYNTAX score ≥23.

This study was conducted with the aim of ascertaining public awareness and attitudes regarding CRC and current screening practices. Furthermore, the study assessed perceived barriers which could impact future screening processes. Methods A cross-sectional, questionnaire-based study was conducted among urban dwellers of Karachi, Pakistan. We excluded any individuals belonging to the medical profession, those diagnosed previously with CRC or having any significant co-morbidity. The validated and pre-tested questionnaire was administered among the study participants to record demographic information, awareness of CRC risk factors, symptoms and screening tests. Attitudes towards screening and perceived barriers to screening were also assessed. Data were analyzed using Statistical Package for Social Sciences (SPSS v...

The acceleration strongly depends upon the initial conditions in the phase space and certain modulation amplitude. We study the accelerated modes by the Poincaré surface of sections and Lyapunov exponents. Furthermore, we identify the initial areas of the phase space that support accelerated dynamics and write a mapping for accelerated dynamics. We show that a distinction between accelerated and chaotic evolutions can be made with the help of the aspect ratio. The Lyapunov exponent shows that the accelerated mode supports ordered evolution.
