The Local Group Census: planetary nebulae in IC 10, Leo A and Sextans A

, 2003
In the framework of our narrow-band survey of the Local Group galaxies, we present the results of the search for planetary nebulae (PNe) in the dwarf irregular galaxies IC10, LeoA and SextansA.

The Abundances of Light Neutron-Capture Elements in Planetary Nebulae. III. The Impact of New Atomic Data on Nebular Selenium and Krypton Abundance Determinations [PDF]

, 2015
The detection of neutron(n)-capture elements in several planetary nebulae (PNe) has provided a new means of investigating s-process nucleosynthesis in low-mass stars.

Influence of Weather Fronts on Design Storm Profiles: Applied Event Partitioning and Comparative Analysis

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Current practices in hydrologic design are based on the exceedance probability of rainfall intensities, without considering the meteorological conditions that generate them. Atmospheric drivers, such as weather fronts, control the spatiotemporal characteristics of storm events, with implications for urban stormwater infrastructure design and ...

The populations of planetary nebulae in the direction of the Galactic bulge

, 2004
We have observed 44 planetary nebulae (PNe) in the direction of the Galactic bulge, and merged our data with published ones. We have distinguished, in the merged sample of 164 PNe, those PNe most likely to prtain physically to the Galactic bulge and ...

The Circumstellar Extinction of Planetary Nebulae [PDF]

, 1998
We analyze the dependence of circumstellar extinction on core mass for the brightest planetary nebulae (PNe) in the Magellanic Clouds and M31. We show that in all three galaxies, a statistically significant correlation exists between the two quantities ...

Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, Volume 36, Issue 24, 23 March 2026.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

A search for hydrogenated fullerenes in fullerene-containing planetary nebulae

, 2016
Detections of C60 and C70 fullerenes in planetary nebulae (PNe) of the Magellanic Clouds and of our own Galaxy have raised the idea that other forms of carbon such as hydrogenated fullerenes (fulleranes like C60H36 and C60H18), buckyonions, and carbon ...

Panchromatic Hubble Andromeda Treasury IX: A Photometric Survey of Planetary Nebulae in M31 [PDF]

, 2014
We search Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) broadband imaging data from the Panchromatic Hubble Andromeda Treasury (PHAT) survey to identify detections of cataloged planetary nebulae (PNe).

Prenatal nicotine exposure induces epigenetic alterations in the Notch signaling genes in the proximal colon in rats

BMC Genomics
Background Prenatal nicotine exposure (PNE) has been shown to significantly impact fetal development, leading to various pathologies in adulthood. Objectives In this study, we analyzed the epigenetic effects of PNE on the proximal colon.
