The role of PTP1B in cardiometabolic disorders and endothelial dysfunction
( Taylor and Francis Ltd. , 2025 , Article Review)Cardiovascular diseases (CVD) are a global health concern that accounts for a large share of annual mortality. Endothelial dysfunction is the main underlying factor that eventually leads to cardiovascular events. Recent ... -
Differential protection against SARS-CoV-2 reinfection pre- and post-Omicron
( Springer Nature , 2025 , Article)The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly evolved over short timescales, leading to the emergence of more transmissible variants such as Alpha and Delta1, 2–3. The arrival of the Omicron ... -
Enhancing eggplant (Solanum melongena L.) yield and water use efficiency through optimized irrigation and nitrogen practices in open field conditions
( Elsevier , 2024 , Article)This study evaluated the interactive effects of deficit irrigation and nitrogen application on eggplant growth and yield under water scarcity in Northern Qatar (2022–2023). Two irrigation regimes were tested: full irrigation ... -
Hepatitis C virus transmission among people who inject drugs in the Middle East and North Africa: mathematical modeling analyses of incidence and intervention impact
( Elsevier , 2025 , Article)BackgroundThe Middle East and North Africa (MENA) region is the most affected by hepatitis C virus (HCV) infection globally. This study aimed to estimate HCV incidence among people who inject drugs (PWID) in MENA and ... -
Evaluating chemiluminescent immunoassays for syphilis detection: A comparative analysis
( Elsevier , 2025 , Article)BackgroundSyphilis, caused by Treponema pallidum (TP), remains a significant global public health concern, with approximately 8 million new cases annually. Diagnosing syphilis is challenging due to its often-asymptomatic ... -
Evaluating Hospital Admission Data as Indicators of COVID-19 Severity: A National Assessment in Qatar.
( Oxford University Press , 2025 , Article)Accurately assessing SARS-CoV-2 infection severity is essential for understanding the health impact of the infection and evaluating the effectiveness of interventions. This study investigated whether SARS-CoV-2-associated ... -
Impact of a potential Chlamydia vaccine in the USA: mathematical modelling analyses.
( BMJ Publishing Group , 2024 , Article)(CT) infection is a global health challenge. New approaches are needed to control CT disease burden. An age-structured deterministic mathematical model calibrated to nationally representative population-based data was ... -
"Your taste in fashion is bad": The role of state of anger in aggressive behavior using the hot sauce paradigm
( Cogent OA , 2020 , Article)This study investigates a mediator of the link between anger induction and subsequent aggressive behavior: the state of anger. One hundred three female participants were randomly assigned to three groups and were given ... -
A fouling-resistant mixed-matrix nanofiltration membrane based on covalently cross-linked Ti3C2TX (MXene)/cellulose acetate
( Elsevier , 2020 , Article)A new fouling-resistant mixed-matrix nanofiltration membrane based on a covalently cross-linked Ti3C2TX (MXene)/cellulose acetate (MXene@CA) composite was fabricated by phase inversion followed by formaldehyde cross-linking. ... -
A new oscillator with mega-stability and its Hamilton energy: Infinite coexisting hidden and self-excited attractors
( American Institute of Physics Inc. , 2020 , Article)In this paper, we introduce an interesting new megastable oscillator with infinite coexisting hidden and self-excited attractors (generated by stable fixed points and unstable ones), which are fixed points and limit cycles ... -
Age could be driving variable SARS-CoV-2 epidemic trajectories worldwide
( Public Library of Science , 2020 , Article)Current geographic spread of documented severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections shows heterogeneity. This study explores the role of age in potentially driving differentials in infection ... -
A novel hybrid secure image encryption based on Julia set of fractals and 3D lorenz chaotic map
( MDPI , 2020 , Article)Chaos-based encryption schemes have attracted many researchers around the world in the digital image security domain. Digital images can be secured using existing chaotic maps, multiple chaotic maps, and several other ... -
A new megastable nonlinear oscillator with infinite attractors
( Elsevier , 2020 , Article)Dynamical systems with megastable properties are very rare in the literature. In this paper, we introduce a new two-dimensional megastable dynamical system with a line of equilibria, having an infinite number of stable ... -
A Bayesian Approach to Competing Risks Model with Masked Causes of Failure and Incomplete Failure Times
( Hindawi Limited , 2020 , Article)We present a Bayesian approach for analysis of competing risks survival data with masked causes of failure. This approach is often used to assess the impact of covariates on the hazard functions when the failure time is ... -
A new megastable chaotic oscillator with singularity
( Springer Science and Business Media Deutschland GmbH , 2020 , Article)While multistability is known as a hot topic in nonlinear dynamics, two exceptional cases of multistable systems have been investigated less: extreme multistable systems and megastable systems are two newer categories of ... -
A linguistically-driven response categorisation protocol for Arabic nouns and verbs: clinical and research applications
( Taylor and Francis Ltd , 2020 , Article)Research into language breakdown in Arabic has been growing in the last two decades. The field, however, remains challenged by the lack of assessment materials, normative databases, and standards for categorising responses ... -
A fractional-order model for the novel coronavirus (COVID-19) outbreak
( Springer , 2020 , Article)The outbreak of the novel coronavirus (COVID-19), which was firstly reported in China, has affected many countries worldwide. To understand and predict the transmission dynamics of this disease, mathematical models can be ... -
Ælfric, Boulogne-Sur-Mer 63, and the Institutio Canonicorum Aquisgranensis Get access Arrow
( Oxford University Press , 2020 , Article Review)The first part of Boulogne-sur-Mer, Biblothèque municipale, MS 63 (fols. 1–34), has long been associated with Ælfric of Eynsham. In Enid Raynes’s examination of the manuscript, she finds a ‘high proportion’ of the texts ... -
A novel secure occupancy monitoring scheme based on multi-chaos mapping
( MDPI , 2020 , Article)Smart building control, managing queues for instant points of service, security systems, and customer support can benefit from the number of occupants information known as occupancy. Due to interrupted real-time continuous ... -
A Power Associative Loop Structure for the Construction of Non-Linear Components of Block Cipher
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)In the symmetric key cryptography, the purpose of the substitution box is to generate confusion and hence improve the security of the whole cryptosystem. For this reason, many algebraic substitution boxes are constructed ...
