Evolutionary Period Changes for 52 Cataclysmic Variables, and the Failure for the Most-fundamental Prediction of the Magnetic Braking Model

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

Population balance modeling and digital design of degree of agglomeration in industrial crystallization

AIChE Journal, EarlyView.
Abstract This study presents a coupled population balance model (PBM) for describing the degree‐of‐agglomeration (DoA) in crystallization by independently tracking total particle and agglomerate number densities. Applied to an industrial active pharmaceutical ingredient, the model outperformed bridge‐counting methods and accurately captured DoA trends ...

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.

New infrared results for classical novae [PDF]

International Astronomical Union Colloquium, 1990
AbstractRecent infrared studies of classical novae are described. The nucleation and growth of dust in nova ejecta was confirmed by optical/infrared photometry of several novae during the past five years including QU Vul, V842 Cen, V827 Her, and QV Vul.

Macrophage Phenotype Detection Methodology on Textured Surfaces via Nuclear Morphology Using Machine Learning

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

Classical novae: Properties between outbursts [PDF]

International Astronomical Union Colloquium, 1990
With the recent publication of Classical Novae, edited by Bode and Evans, there is no need for me to give a list of novae or their overall characteristics. Furthermore, probably the most interesting developments in the past few years in studies of novae during quiescence have been in those areas (magnetic systems, long term brightness variations) which

Temperature‐Controlled Radiofrequency for Severe Nasal Airway Obstruction: A Non‐Inferiority Comparison With Surgical Intervention

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Temperature‐controlled radiofrequency (TCRF), septoplasty (ST) with turbinate reduction, and functional rhinoplasty (FR) are treatment options for nasal airway obstruction (NAO) and nasal valve dysfunction (NVD), but no direct comparison of these procedures has been performed. Methods This prospective, open‐label, non‐inferiority (

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Detection of a Molecular Hydrogen Envelope around Nova GK Persei

The Astrophysical Journal Letters
The eruption of Nova Persei 1901 (GK Per) occurred 125 yr ago; remarkably, it still holds major surprises. Using data from the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx), we find that it has a ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.
