The theory of operators is an important subject in analytic function theory, geometric function theory and univalent function theory. It also is an important subject in applied sciences. It is still an active field of research and various types of problems, which can be solved by generalising operators. Recently, many researchers have shown great interests in the study of differential operators in the theory of univalent functions and various subclasses of analytic functions defined in the open unit disc. In this paper a generalised derivative operator will be used to derive some results concerning the subordination and superordination of analytic function in the open unit disc.

The division algorithm for multivariate polynomials over fields has been introduced not very long ago, in connection with algorithmic and computational problems in the rings since the work of Buchberger. The well-known fact is a term order must be a well-ordering and the division procedure in the ring of multivariate polynomials over a field terminates even if the division term is not leading term, but is freely chosen. In this paper, we will show the original geometric approach to the classification of all possible orders on the ring of polynomials in two variables is given. The connection between this classification and the well-known classification of Robiano is exposed in details

This systematic review investigates the impact of the COVID-19 pandemic on cybersecurity by examining the rise of cyberattacks targeting financial institutions. By analyzing over 60 sources including academic research, government reports, and security company data, the review reveals a nearly two-fold increase in cybercrimes targeting financial institutions during the pandemic compared to pre-pandemic levels. Phishing attacks are identified as the most prevalent form of cybercrime within this context. The review delves further by analyzing the differences between phishing and other cyberattacks during COVID-19. Based on the results and observations presented in this paper, the analysis will contribute to enriching strategies to address the growing threat of cybercrime in the financial sector

Abstract: This paper focuses on the challenging task of counting the number of people in digital still images, which has important applications in many fields such as security, management, education, and commerce. This paper proposes a system that is based on the Viola-Jones face detection methods. This system consists of two parts: a) face detection and b) counting the detected faces. In the face detection part, the Viola-Jones (LBP and CART feature extraction) algorithm is applied to the input image. In the counting part, the detected faces are counted to estimate the number of people in the given image. The Viola-Jones algorithm is applied using 133 images from the People Image Groups dataset, and the best precision achieved is 96.9%. Overall, this paper presents a promising system for accurately counting the number of people in digital static images using a simple and costeffective approach

Abstract

Seven male specimens (one immature and six adults) of a rare species of Loureedia jerbae (El-Hennawy, 2005), are recorded for the first time in Libya, representing the first record of this species outside of Tunisia. Illustrations and a description are provided. Only the most recent adult of the specimens captured in October/November of 2019 to 2022 was examined, identified and described. Although Libya has one of the least recorded spider species in the Mediterranean region, it is promising to reveal more undiscovered and undocumented species through extensive research in this large country

The genus Segestria Latreille, 1804 and the species Segestria florentina (Rossi, 1790) are recorded in Libya for the first time, based on a single adult female specimen

The battle against COVID-19 does not always end when recovery is declared. Many individuals confirmed recovered from COVID-19 continue to experience a variety of symptoms. The aim of this study was to shed more light on COVID-19 and post-COVID-19 symptoms in Libya. Two hundred and twenty Libyan individuals (58% female; 42% male), who recovered from COVID‐19, were asked to answer a questionnaire that was performed to inquire about the presence of COVID-19 and post-COVID-19 symptoms. Additionally, comorbidities and demographic data were included. The most common comorbidities were hypertension (20%), diabetes (16%), and lung disease (08%). The main COVID-19 symptoms were headache (56%), anosmia and ageusia (52%), Arthralgia (48%), cough (46%) and fever (41%). While the post-COVID-19 symptoms were fatigue (64%), sleep disorders (52%), insomnia, anxiety, depression (42%), and anosmia and ageusia (32%). Persistent COVID and its related long-term complications may continue to affect patients and their families.
