Out There No One Has a Right to Die

open access: yesBioethics, EarlyView.
ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Toll‐like receptor 4 mediates lipopolysaccharide‐induced emesis

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Lipopolysaccharide (LPS) induces inflammation and sepsis through Toll‐like receptor 4 (TLR4) activation. Common laboratory animals do not exhibit emesis, but administration of LPS in piglets, cats, and dogs induces emesis via peripheral mechanisms.

The Role of Active Galactic Nucleus Winds in Galaxy Formation: Connecting AGN Outflows at Low Redshifts to the Formation/Evolution of Their Host Galaxies

open access: yesThe Astronomical Journal
Using Sloan Digital Sky Survey (SDSS) spectra, we applied an automatic method to search for outflows (OFs) in three large samples of narrow-line active galactic nuclei (AGN) at low redshifts ( z < 0.4), separated into three spectral activity classes ...

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Questions Should Have Answers

open access: yesEuropean Journal of Philosophy, EarlyView.
ABSTRACT Making sense of the world often requires one to come up with new ideas, including ideas one had previously been unable to think of. How and when should this be done? I propose and defend a norm of rationality linking wondering, belief, and abilities to conceive: one must not both wonder a question and reject all answers to it that one can ...

JWST Insights into Narrow-line Little Red Dots

open access: yesThe Astrophysical Journal
JWST has revealed a population of red and compact objects with unique “V-shaped” spectral energy distributions (SEDs) known as “Little Red Dots” (LRDs). Many LRDs exhibit broad Balmer lines and thus likely host active galactic nuclei (AGNs).

Environments of high and low excitation radio galaxies

open access: yesAstronomy & Astrophysics
Aims. Active galactic nuclei (AGNs) play a crucial role in shaping galaxy evolution through their feedback mechanisms. Low-excitation radio galaxies (LERGs) and high-excitation radio galaxies (HERGs) are thought to exhibit distinct feedback modes, and ...

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Different Dependence of Narrow Hα Line Luminosity on Optical Continuum Luminosity between Star-forming Galaxies and Type 2 Active Galactic Nuclei: Globally Negative AGN Feedback in Local Type 2 AGN?

open access: yesThe Astrophysical Journal
In this manuscript, clues are provided to support globally negative active galactic nuclei (AGN) feedback on star formation in the host galaxies of the local low-redshift Sloan Digital Sky Survey (SDSS) Type 2 AGN, based on the different dependence of ...
