Sakr, A. H., "Dynamics of Heaving Buoy Wave Energy Converters with a Stiffness Reactive Controller", Energies, vol. 14, no. 1, 2021. AbstractWebsite

Heaving buoy wave energy converters (WEC) are floating oscillators, commonly modeled as single-degree-of-freedom vibrating systems. As the wave frequencies change according to the sea state, these devices must be controlled to maximize energy absorption. A new short-term reactive loading control technique is proposed that maximizes power absorption. The control is realized through tuning the effective stiffness of the vibrating system; thus, adjusting its natural frequency to meet the incident waves energy frequency achieving near-to-resonance operation and maximum power absorption. This stiffness is adjusted using an external stiffness, whose value is varied by a continuously variable transmission (CVT) mechanism connected to the buoy. The system equations were derived then solved analytically to calculate the controller bandwidth. Experiments demonstrated promising results for near-resonance tuning at different input frequencies. Results show that an optimized damping value exists at which power absorption can be significantly increased. The WEC equipped with the proposed reactive controller can provide faster tuning actions than long-term techniques. It also works on longer time intervals than phase-control methods; hence, reducing the continuous demands from the PTO system.

Selwaness, I., and C. Krafft, "The Dynamics of Family Formation and Women’s Work: What Facilitates and Hinders Female Employment in the Middle East and North Africa?", Economic Research Forum Working Paper Series No. 1192. Cairo, Egypt, 2018. Abstract

This paper investigates the dynamic relationship between family formation and women’s employment, a previously unexplored aspect of female labor force participation in MENA region. The paper studies Egypt, Jordan and Tunisia, leveraging unique retrospective data on work, marriage, child bearing and child rearing. The time variation allows us to estimate discrete hazard models for the duration of different labor statuses. This paper examines three sets of outcomes:(1) duration in employment,(2) duration in non-employment, and (3) duration in different labor market states and specific types of work. Findings show that anticipating marriage and childbearing are strongly associated with women’s employment outcomes. Non-employment is an absorbing state, particularly after marriage.

Gastal, "Dynamics of extracellular vesicle-coupled microRNAs in equine follicular fluid associated with follicle selection and ovulation", Molecular Human Reproduction, 02, 2023. AbstractWebsite

{Innumerable similarities in reproductive cyclicity and hormonal alterations highlight the considerable utility of the mare to study aspects of follicular dynamics and reproductive function in view of the largely constricted, human research subjects. The bi-directional communication between the growing oocyte and the surrounding somatic cells embodies the hallmark of mammalian follicular development, partially mediated by extracellular vesicles (EVs) encapsulated with microRNAs (miRNAs) and present in the follicular fluid (FF). Here, we aimed to decipher the dynamics of the miRNAs in EVs from equine FF aspirated in vivo during different stages of follicular development, namely, predeviation (PreDev; 18–20 mm), deviation (Dev; 22–25 mm), postdeviation (PostDev; 26–29 mm), preovulatory (PreOV; 30–35 mm), and impending ovulation (IMP; ∼40 mm). Approximately 176 known miRNAs were found in all groups with 144 mutually detected among all groups. Cluster analysis exhibited 15 different expression patterns during follicular development. Among these patterns, a group of 22 miRNAs (including miR-146b-5p, miR-140, and miR-143) exhibited a sharp reduction in expression from the PreDev until the PreOV stage. Another cluster of 23 miRNAs (including miR-106b, miR-199a-5p, and miR-125a-5p) exhibited a stable expression pattern at the PreDev stage until the PostDev stage, with a significant increase at the PreOV stage followed by a significant decrease at the IMP stage. In conclusion, this study provides greater insights into the stage-specific expression dynamics of FF EV-miRNAs during equine follicular development, which may propose novel approaches to improve ART and provide new biomarkers to facilitate the assessment of ovarian pathophysiological conditions.}

Eid, A., "Dynamics of charged shell with a cosmological constant", New Astronomy, vol. 44, pp. 17 - 20, 2016. AbstractWebsite

Abstract Using the Darmois–Israel formalism technique, charged thin shell in the presence of a cosmological constant is constructed. An equation governing the behavior of the radial pressure across the junction surface is deduced. The cosmological constant term and the charge term slows down the collapse of matter. The spherical N-shell model with an appropriate initial condition imitates quite well the \{FRW\} universe with Λ ≠ 0.
