The Orientation of Jets Relative to Dust Disks in Radio Galaxies [PDF]

open access: yes, 2002
We use Hubble Space Telescope broadband images and VLA and VLBI continuum data to study the three-dimensional orientation of jets relative to nuclear dust disks in 20 radio galaxies. The comparison between the position angles of the jets and those of the

Hunting for Paradoxes: A Research Strategy for Cognitive Science

open access: yesTopics in Cognitive Science, EarlyView.
Abstract How should we identify interesting topics in cognitive science? This paper suggests that one useful research strategy is to hunt for, and attempt to resolve, paradoxes: that is, apparent or real contradictions in our understanding of the mind and of thought.

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Chandra finds that X-ray jets are common in low-power radio galaxies [PDF]

open access: yes, 2001
We present results for the first three low-power radio galaxi es from the B2 bright sample to have been observed with Chandra. Two have kpc-scale radio jets, and in both Chandra resolves jet X-ray emission, and detects soft X-ray core emission and an X ...

Circadian clock disruption promotes retinal photoreceptor degeneration

open access: yesThe FASEB Journal, Volume 39, Issue 7, 15 April 2025.
Mice carrying a knock‐in of the P23H mutation of the rhodopsin gene are a well‐characterized model of retinitis pigmentosa (RP), a hereditary retinal degeneration affecting primarily rods. Here, by combining the P23H Rho mutation with the rod‐specific invalidation of the Bmal1 clock gene and by performing functional, structural, and molecular analyses,

Trophic Plasticity of the Invasive Redbelly Tilapia (Coptodon zillii) in China Inferred From DNA Metabarcoding Analysis

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
The feeding patterns of invasive populations of C. zillii in different habitats and seasons within a large‐scale geographic area (spanning 9.86° latitude and 10.47° longitude) in China were directly compared. ABSTRACT The redbelly tilapia (Coptodon zillii) is one of the most dangerous invasive alien fishes in the world.

A dichotomy in the orientation of dust and radio jets in nearby low-power radio galaxies [PDF]

open access: yes, 2005
We examine the properties of central dust in nearby quiescent and active early-type galaxies. The active galaxies are low-power radio galaxies with Fanaroff & Riley type I or I/II radio jets.

The Magnetosphere‐Ionosphere‐Ground Responses to the May 2024 Super Solar Storm

open access: yesSpace Weather, Volume 23, Issue 4, April 2025.
Abstract Earth suffered the attack of the strongest geomagnetic storm in the last 20 years (Kp = 9, Dst∼ ${\sim} $ −400 nT) occurred on 11 May 2024. Taking advantage of the LEO multi‐parameter CSES satellite (launched in 2018) with a large inclination angle 97° $97{}^{\circ}$, with the joint observations of NOAA and GOES, we present a comprehensive ...
