The Cyclic Evolution of Classical Novae [PDF]
International Astronomical Union Colloquium, 1990 The cyclic evolution of classical novae (CN) cannot be observed, as in the case of recurrent or dwarf novae. The duration of a typical cycle may range from a few thousand to a few 105 years. Thus we have to rely on theoretical studies for understanding the periodic outbursts — due to thermonuclear runaways (TNR) — on the surface of accreting white ...

Advanced Science, EarlyView.This study elucidates how steric hindrance in amines creates a dual effect in CO2 capture: it thermodynamically favors the reaction by shifting the pathway from carbamate to alkyl carbonate formation, increasing capacity and lowering regeneration heat, while simultaneously slightly slowing the kinetics.

The Astrophysical JournalThe evolution of cataclysmic variables (CVs) is driven by period changes ( $\dot{P}$ ), for which the long-venerable consensus is the magnetic braking model (MBM).

The 30P(p, γ)31S reaction in classical novae: progress and prospects
AIP Advances, 2014 The unknown thermonuclear rate of the 30P(p, γ)31S reaction at classical-nova temperatures currently prohibits the accurate modeling of nova nucleosynthesis in the A ⩾ 30 region.

Orbital eccentricity in classical novae [PDF]
Nature, 1987 The effect on the orbital parameters of a classical nova of the ejection of mass during the nova explosion is considered. The most easily observable consequence is the generation of a small eccentricity in the orbit which leads to a luminosity modulation at a period just longer than the orbital period.

Advanced Intelligent Discovery, EarlyView.A novel machine learning approach classifies macrophage phenotypes with up to 98% accuracy using only nuclear morphology from DAPI‐stained images. Bypassing traditional surface markers, the method proves robust even on complex textured biomaterial surfaces. It offers a simpler, faster alternative for studying macrophage behavior in various experimental

A Multiepitope‐Based Lateral Flow Assay for Leprosy Antibodies
Analysis &Sensing, EarlyView.An innovative lateral flow assay for leprosy diagnosis is based on gold nanoparticles and synthetic Mycobacterium leprae epitopes conjugated to keyhole limpet hemocyanin protein to enhance antibody detection. This strategy provides a rapid, accurate, and low‐cost approach for resource‐limited settings, enabling the early detection of infection. Leprosy

Analysis &Sensing, EarlyView.The graphical abstract shows an eco‐friendly approach to fabricating a biodegradable electrochemical sensor. Carbon quantum dot/nickel oxide (CQD/NiO) nanocomposites are synthesized using Aloe arborescens leaf extract, which served as a natural reducing and stabilizing agent.
