Out There No One Has a Right to Die

Bioethics, 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

British 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.

High-frequency Fast Radio Burst Search of Nearby Star-forming Galaxies M77 and M82

The Astrophysical Journal
The astrophysical origins of fast radio bursts (FRBs) are still unknown, but magnetars are a strong candidate for producing at least some FRBs. To investigate the magnetar progenitor model, we conducted a deep search of M77 and M82, two nearby galaxies ...

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer 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.

Stellar Metallicities and Gradients in the Faint M31 Satellites Andromeda XVI and Andromeda XXVIII

The Astrophysical Journal
We present ∼300 stellar metallicity measurements in two faint M31 dwarf galaxies, Andromeda XVI ( M _V = −7.5) and Andromeda XXVIII ( M _V = –8.8), derived using metallicity-sensitive calcium H and K narrowband Hubble Space Telescope imaging.

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

Computer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

Questions Should Have Answers

European 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 ...

Stellar Mass Assembly History of Massive Quiescent Galaxies since z ∼ 4: Insights from Spatially Resolved Spectral Energy Distribution Fitting with JWST Data

The Astrophysical Journal
Massive quiescent galaxies at high redshift show significantly more compact morphology than their local counterparts. To examine their internal structure across a wide redshift range and investigate potential redshift dependence, we performed spatially ...

PanGraphRNA: An efficient and flexible bioinformatics platform for graph pangenome‐based RNA‐seq data analysis

Journal of Integrative Plant Biology, EarlyView.
PanGraphRNA is an easy‐to‐use platform that improves RNA‐seq analysis by using graph pangenomes instead of a single reference genome. It increases read alignment accuracy, detects important genes missed by traditional methods, and works across major crops, helping researchers obtain more reliable transcriptome results for diverse plant research and ...

Quantifying the Escape of Lyα at z ≈ 5–6: A Census of Lyα Escape Fraction with Hα-emitting Galaxies Spectroscopically Confirmed by JWST and VLT/MUSE

The Astrophysical Journal Supplement Series
The James Webb Space Telescope provides an unprecedented opportunity for unbiased surveys of H α -emitting galaxies at z > 4 with the NIRCam's wide-field slitless spectroscopy (WFSS).
