Variations in Satellite Charge Drag Coefficient With Solar Cycle

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Ionospheric plasma interaction with charged satellite surfaces can lead to a substantial increase in orbital drag. In this context, natural events related to solar activity can have a detrimental effect on a satellite's lifespan and introduce uncertainty in orbital trajectory predictions.

Heated granular fluids: the random restitution coefficient approach

, 2001
We introduce the model of inelastic hard spheres with random restitution coefficient $\alpha$, in order to account for the fact that, in a vertically shaken granular system interacting elastically with the vibrating boundary, the energy injected ...

Solution to Asymptotic Stability in Tracking Control of Nonlinear Systems With Control Input Differentiation, Actuator Dynamics, and Saturation Constraints

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
The work delivers a rigorous mathematical framework for asymptotic tracking in nonlinear systems that explicitly include control‐input derivatives, actuator dynamics, and input saturation, with Lyapunov‐based proofs establishing convergence and robustness under their coupled effects.

Gas Flow and Heat Transfer in an Enclosure Induced by a Sinusoidal Temperature

Journal of Applied Fluid Mechanics, 2019
The heat transfer and flow characteristics of rarefied gas confined within a square cavity are investigated. The cavity upper-wall is subjected to a symmetrical sinusoidal temperature with respect to its midline.

Twice‐Weekly Oral Iron–Folic Acid Supplementation Is an Alternative to a Daily Regimen in Pregnancy: An Open‐Label, Randomized, Active‐Controlled, Noninferiority Trial

Anemia, Volume 2026, Issue 1, 2026.
Background The weekly intake of oral iron–folic acid in pregnancy is an optional recommendation by the World Health Organization and the International Federation of Gynaecology and Obstetrics (FIGO). Although evidence was limited to justify its benefit or harm in Ethiopia, weekly iron–folic acid could be optional in the regions of Ethiopia.

Pereskia aculeata Leaves as a Functional Food: Neurobehavioral and Redox Homeostasis Protection of Aged Drosophila melanogaster Against Paraquat Exposure

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
The aim of this study was to investigate the nutritional composition and functional properties of Pereskia aculeata Miller, known as Ora‐pro‐nóbis (OPN), and to evaluate whether dietary supplementation enhances resistance to paraquat‐induced oxidative stress in aged Drosophila melanogaster.

Differences in plasmatic and CSF Alzheimer's Disease biomarkers considering ApoE genotype in mild cognitive impairment and subjective cognitive decline

Alzheimer's &Dementia, Volume 21, Issue S2, December 2025.
Abstract Background Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder, and ApoE ε4 allele is the most relevant genetic risk factor for sporadic AD. Although it is well‐known that ApoE ε4 is related to brain amyloidosis, much less is known whether this genetic risk factor may influence Aβ and tau plasmatic levels in the mildest ...

Plasma biomarkers are related to white matter integrity in alzheimer's disease continuum

Alzheimer's &Dementia, Volume 21, Issue S2, December 2025.
Abstract Background Plasma biomarkers (PB) of Alzheimer's disease (AD) is a non‐invasive and economic alternative for early diagnosis. Due to the increasing incidence of dementia worldwide, understanding the relationship between PB and other AD biomarkers, such as neuroimaging is necessary.
