Aggregate, EarlyView.Due to the combinational effects of strong non‐aromatic through‐bond conjugation (TBC) and through‐space conjugation (TSC), dihydropyridine derivatives exhibit photoluminescent behaviors between those of traditional luminogens (TLs) and nontraditional luminogens (NTLs), thus bridging the gap between TLs and NTLs.

Ejection of Supernova-Enriched Gas From Dwarf Disk Galaxies [PDF]
Astrophys.J. 617 (2004) 1077-1090, 2004 We examine the efficiency with which supernova-enriched gas may be ejected from dwarf disk galaxies, using a methodology previously employed to study the self-enrichment efficiency of dwarf spheroidal systems. Unlike previous studies that focused on highly concentrated starbursts, in the current work we consider discrete supernova events spread ...

Proceedings of 8th European VLBI Network Symposium — PoS(8thEVN), 2007 In this article I will briely review the current status of radio observations of nearby supernovae and their remnants. This review will initially address observations of the radio light curves of nearby core-collapse supernovae, followed by a more detailed summary of recent Very Long Baseline Interferometric observations of the expansion of nearby ...

The Anatomical Record, EarlyView.Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Supernova Dust Evolution Probed by Deep-sea 60Fe Time History
The Astrophysical Journal, 2023 There is a wealth of data on live, undecayed ^60 Fe ( t _1/2 = 2.6 Myr) in deep-sea deposits, the lunar regolith, cosmic rays, and Antarctic snow, which is interpreted as originating from the recent explosions of at least two near-Earth supernovae.

A Slowly Pulsating Run‐Away B Star at High Galactic Latitude Ejected From a Spiral Arm
Astronomische Nachrichten, EarlyView.ABSTRACT We report the discovery of the young B6 V run‐away star LAMOST J083323.18 + 430825.4, 2.5 kpc above the Galactic plane. Its atmospheric parameters and chemical composition are determined from LAMOST spectra, indicating normal composition. Effective temperature (Teff$$ {T}_{\mathrm{eff}} $$ = 14,500$$ \mathrm{14,500} $$ K) and gravity (logg ...

Fundamental physics studies in time domain and multi-messenger astronomy
Frontiers in Astronomy and Space SciencesThe era of ime domain and multi-messenger astronomy is not only leading to the development of a much broader set of detectors and instruments for astrophysical observations, but is also providing the means for astronomy to tie directly to cutting-edge ...

Neutrino flavor instabilities in a time-dependent supernova model
Physics Letters B, 2015 A dense neutrino medium such as that inside a core-collapse supernova can experience collective flavor conversion or oscillations because of the neutral-current weak interaction among the neutrinos.
