Small, EarlyView.Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

Extragalactic eclipsing binaries: astrophysical laboratories [PDF]
New Astronomy Reviews, 2004 Eclipsing binaries (EBs) have long been known for providing accurate stellar fundamental properties, such as masses and radii. These are obtained from the modeling of light and radial velocity curves and, with input data of good quality, uncertainties of a few percent in the components’ physical properties are now routinely achieved.

Unlocking n‐alk‐1‐ynes conformers: Quantum “trigger finger” versus “stiff joint” conformations
Smart Molecules, EarlyView.Quantum chemical analysis reveals the unique function of n‐alk‐1‐yne terminus as a Quantum “Trigger Finger,” exhibiting two near‐isoenergetic conformers (Cs ${\mathrm{C}}_{s}$and C1 ${\mathrm{C}}_{1}$) locked by a symmetric high barrier. This contrasts with the lower asymmetric barrier of the conventional asymmetric “Stiff Joint” alkyl chain.

Identity Entanglement: Rethinking Marginality through the Intersectional, Liminal, and Antithetical
Symbolic Interaction, EarlyView.While identity research has given sustained attention to marginality, intersectionality, and the effects of power on identity, the formal interactional dynamics through which identities are constituted remain limited. I present identity entanglement as a useful framework for better understanding and articulating the relational complexities of identity.

Turbulence in the Atmospheres of Eclipsing Binary Stars [PDF]
International Astronomical Union Colloquium, 1980 Abstract:A review of the orbits and dimensions of the ζ Aurigae systems is given, based on photometric and spectrographic observations. The Ca II K-line has been studied intensively to determine the extent and uneven structure of the chromospheres of these stars; the multiple structure of this line observed at several eclipses confirms the presence of ...

CAAI Transactions on Intelligence Technology, EarlyView.Abstract Internet of Medical Things (IoMT) has typical advancements in the healthcare sector with rapid potential proof for decentralised communication systems that have been applied for collecting and monitoring COVID‐19 patient data. Machine Learning algorithms typically use the risk score of each patient based on risk factors, which could help ...

Fine‐scale spatial variation in eastern grey squirrel melanism across a complex urban landscape
Journal of Animal Ecology, EarlyView.By sampling 197 parks, the study demonstrates how natural geography creates divergence within cities. The findings reveal that the St. Lawrence River and its tributaries act as barriers, disrupting urban melanism clines in grey squirrels. Ultimately, the research indicates that natural features still dictate evolutionary rules in anthropogenic ...

The Big Picture: Religion and Global Comparative History
Journal of Religious History, EarlyView.This article considers what a ‘big picture’ approach to global religious history might look like, and in particular the implications of deploying the comparative method across much larger stretches of time and space than historians normally attend to. It will begin by reflecting on the epistemological moods that have hindered this project to date, the ...

, 2004 The first eclipsing binary pulsar, PSR B1957+20, was discovered in 1987. Since then, 13 other eclipsing low-mass binary pulsars have been found, 12 of these are in globular clusters. In this paper we list the known eclipsing binary pulsars and their properties, with special attention to the eclipsing systems in 47 Tuc.
