Why are classical bulges more common in S0 galaxies than in spiral galaxies? [PDF]
, 2018 In this paper, we try to understand why the classical bulge fraction observed in S0 galaxies is significantly higher than that in spiral galaxies. We carry out a comparative study of the bulge and global properties of a sample of spiral and S0 galaxies in a fixed environment.

The possible evolution of pitch angles of spiral galaxies [PDF]
arXiv, 2023 The origin and maintenance of spiral structure in galaxies, the correlation between different types of spiral structure and several proposed mechanisms for their generation, and the evolution of spiral arms of galaxies with time are questions that are still controversial.

Towards Scaling‐Invariant Projections for Data Visualization
Computer Graphics Forum, EarlyView.Abstract Finding projections of multidimensional data domains to the 2D screen space is a well‐known problem. Multidimensional data often comes with the property that the dimensions are measured in different physical units, which renders the ratio between dimensions, i.e., their scale, arbitrary.

Modified Newtonian Dynamics: A Falsification of Cold Dark Matter
Advances in Astronomy, 2009 The only viable alternative to dark matter is one in which Newtonian dynamics or gravity breaks down in the limit of low accelerations, as in modified Newtonian dynamics (MONDs).

‘The non‐dormant beast’: Antisemitism in communities of Russian nationalists on Vkontakte
Nations and Nationalism, EarlyView.Abstract The article explores the specifics of Russian antisemitic discourse of recent years using the example of three nationalist communities on Vkontakte, the most popular Russian social networking site, by means of critical discourse analysis. The main strategies they employ to frame the Jews online are stereotyping Jews as ungrateful and greedy ...

International Journal of Engineering and Management Sciences, 2018 Recently, it has been suggested that entangled particles may be connected by a wormhole. If that is right, what is the distance between them we have to take into account when applying Newton's law of universal gravitation to these particles?

Unique starch biosynthesis pathways in wild rice revealed by multi‐omics analyses
Plant Biotechnology Journal, EarlyView.Summary Australian wild rice species (AWS) possess unique starch properties characterized by a slow digestibility rate. However, the genomic and transcriptomic variations of starch‐synthesis‐related genes (SSRGs) influencing starch physiochemical properties in AWS remain unclear.

The X-Ray Binary-star Cluster Connection in Late-type Galaxies
The Astrophysical Journal, 2023 We conduct one of the largest systematic investigations of bright X-ray binaries (XRBs) in both young star clusters and ancient globular clusters (GCs) using a sample of six nearby star-forming galaxies.

Short-term dynamical evolution of grand-design spirals in barred galaxies [PDF]
, 2015 We investigate the short-term dynamical evolution of stellar grand-design spiral arms in barred spiral galaxies using a three-dimensional (3D) $N$-body/hydrodynamic simulation. Similar to previous numerical simulations of unbarred, multiple-arm spirals, we find that grand-design spiral arms in barred galaxies are not stationary, but rather dynamic ...

Plasticity of the heart in response to changes in physical activity
The Journal of Physiology, EarlyView.Abstract figure legend The heart adapts to changes in physical activity, with inactivity (e.g. bed rest or spaceflight) causing cardiac atrophy and ventricular stiffening, and endurance exercise training leading to eccentric hypertrophy and improved ventricular compliance.
