Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT

Astronomische Nachrichten, EarlyView.
ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

Influence of Dynamical Friction on the Unstable Manifolds of Lagrange Points in Barred Galaxies

Astronomische Nachrichten, EarlyView.
ABSTRACT Some time ago the idea has been proposed that rings and spirals in barred galaxies are shaped by the unstable manifolds of the Lagrange points sitting near the ends of the bar. The topic of the present article is an investigation of whether the numerical support for this suggestion can be improved by the inclusion of dynamical friction into ...

The Preprint Evolution: The Rise of Unreviewed Drafts on arXiv and Its Implications for Astronomy

Astronomische Nachrichten, EarlyView.
ABSTRACT The arXiv preprint server originally democratized astronomical research by removing the financial barriers of journal subscriptions. However, a system designed for the lower publication volumes of the 1990s has fractured under modern research output. Today, the sheer volume of unreviewed manuscripts—often tagged as “submitted,” “under review,”
