Adaptive Array Antennas For Mobile Earth Stations: A Review, Sami Alio, Lamis Kudsi

Information Sciences Letters

satellite-mobile communication is currently one of the most growing areas in the field of telecommunications. However, the interference and the multi-path fading are still considered as major problems for receiving a dependable signal in such systems and this can generally lead to a significant degradation in their performance. One interesting solution to mitigate this problem is to utilize adaptive antenna array systems on the mobile user terminals. These systems will be used to steer the radiation pattern towards the satellite signal and to dynamically put nulls in the direction of the interference and the multi-path signals. This will be done …

An Effective Method Of Systems Requirement Optimization Based On Genetic Algorithms, M. H. Marghny, H. M. El-Hawary, Wathiq H. Dukhan

Information Sciences Letters

Requirements engineering is the first step of software development process and it is one of the main concerns of software engineers. System requirements selection is the engineering process to select an optimal set of system requirements for implementation in the next system of the software from many requirements proposed by the customers on condition that budget and customer satisfaction are being balanced. This NP-hard problem is an important issue involving several conflicting objectives that have to be processed by software companies when developing new software systems. Software systems have to perform their function within resource constraints, but they also have …

Group Norms As Moderator In The Effect Of Cross Group Friendship On Outgroup Attitude: A Study On Interreligious Group In Indonesia, Whinda Yustisia

Makara Human Behavior Studies in Asia

Past studies indicate that the effect of intergroup contact on outgroup attitude is not isolated to contextual factors. One of the contextual factors that has begun to be studied is group norm. However, group norm in these studies is still merely conceptualized as the perception of how ingroup members evaluate outgroup members. In fact, according to norm focus theory, in a given context, individuals are influenced, at least, by two types of group norms, namely injunctive norms (i.e., what most people morally accept to do) and descriptive norms (i.e., what most people do). To fill the gap, present studies attempt …

This study was conducted to determine whether T cell populations are responsible for modulating placental development during gestation in cattle. It was hypothesized that CD4+CD25+ and γ/δ+ T cells modulate gene expression, based on mRNA transcript abundances, and promote proliferation and survival of trophoblast cells. Peripheral blood was collected from cows at 160 to 180 days of gestation and non-pregnant cows, T cell populations CD8+, CD4+, CD4+CD25+, CD24+CD25-, and γ/δ+ T cells were isolated, cultured for 48 h, and supernatant was collected. Placental samples were digested, and trophoblast cells were cultured for 24 h. Trophoblast cells were cultured with 50 …

Interplay Between Oxidative Stress, Sirt1, Reproductive And Metabolic Functions, Faiza Alam, Hareem Syed, Sofia Amjad, Mukhtiar Baig, Taseer Ahmed Khan, Rehana Rehman

Department of Biological & Biomedical Sciences

Silent information Regulators (SIRT1) gene stimulates antioxidants' expression, repairs cells damaged by oxidative stress (OS), and prevents the cells' dysfunction. In particular, the role of different Sirtuins, particularly SIRT1 in reproduction, has been widely studied over the past decade. Decreased SIRT 1 causes mitochondrial dysfunction by increasing Reactive Oxygen Species (ROS), lipid peroxidation, and DNA damage in both male and female gametes (Sperms and Oocytes), leading to infertility. In the female reproductive system, SIRT1 regulates proliferation and apoptosis in granulosa cells (GCs), and its down-regulation is associated with a reduced ovarian reserve. SIRT1 also modulates the stress response to OS …

First-Principles Study Of A Mos2-Pbs Van Derwaals Heterostructure Inspired By Naturally Occurring Merelaniite, Gemechis Degaga, Sumandeep Kaur, Ravindra Pandey, John Jaszczak

Michigan Tech Publications, Part 1

Vertically stacked, layered van der Waals (vdW) heterostructures offer the possibility to design materials, within a range of chemistries and structures, to possess tailored properties. Inspired by the naturally occurring mineral merelaniite, this paper studies a vdW heterostructure composed of a MoS2 monolayer and a PbS bilayer, using density functional theory. A commensurate 2D heterostructure film and the corresponding 3D periodic bulk structure are compared. The results find such a heterostructure to be stable and possess p-type semiconducting characteristics. Due to the heterostructure’s weak interlayer bonding, its carrier mobility is essentially governed by the constituent layers; the hole mobility is …

Intent Prediction Based On Contextual Factors For Better Automatic Speech Recognition, Diamantino Caseiro, Zelin Wu, Petar Aleksic, Era Jain

Defensive Publications Series

Automatic speech recognition (ASR) machine learning models are used to recognize spoken commands or queries from users. End-to-end ASR models, which directly map a sequence of input acoustic features into a sequence of words, greatly simplify ASR system building and maintenance. This disclosure describes techniques to improve the performance of end-to-end ASR models by providing predicted user intents as additional inputs. Intent prediction vectors or intent embedding is generated based on user-permitted contextual features using a trained intent prediction network (IPN). The IPN can be trained independently from the ASR model or jointly with the ASR model. Training of the …

In this paper, images have been used as a cover file, because of …

Self-Adaptive Dna-Based Steganography Using Neural Networks, Marghny H. Mohammed, Botheina H. Ali, Ahmed I. Taloba

Information Sciences Letters

Steganography is the science of concealing the secret information within a digital cover-object such as the files text, image, video and etc. Recently, the deoxyribonucleic acid (DNA) sequences are used as a cover-object for data hiding. In this work, an effective algorithm called the self-adaptive DNABS (DNA-based steganography) is proposed. This algorithm is applied for data hiding without changing the function or the type of the original DNA protein. It is implemented using a DNA-based steganography and a Neural Network (backpropagation) algorithm to achieve a lower cracking probability than other techniques. The performance of the algorithm is analyzed and tested …

The Schro ̈Dinger’S Cat Paradox In The Mind Creative Process, Dione ́Ia Motta Monte-Serrat, Brenno Caetano Troca Cabella, Carlo Cattani

Information Sciences Letters

This article, through Schro ̈dinger’s cat theory, points to a conflict between individuality and universality in the creative process that would appear to be an inconsistency of cognition. We chose the axiomatic-logical concept of language as a system of oppositions of places and values for this discussion, understood as a complex phenomenon mediating between the human mind and the environment. Creativity involves language and cognition and is of interest to artificial intelligence, AI, thus, an in-depth look at creative aspects of the human mind helps to better understand the structure of natural language and gives wagers for new AI challenges. …

Content Analysis Of Lighting And Color In The Embodiment Of Fear Concept In Horror Movies: A Semiotic Approach, Sawsan Mohammed Ezzat Ibrahim Ammer
