NO THE HOLMBERG EFFECT FOR GALAXY PAIRS SELECTED FROM THE SDSS DR9 AT Z ≤ 0:06
We studied the Holmberg effect in galaxy pairs selected from the SDSS DR9, where 60561galaxies were limited by redshift 0.02 < z < 0.06 and absolute magnitude: Mr ≤ −20.7 m for central galaxies (N=18578) and Mr > −21.5 m for neighbor galaxies (N=41983 ...

On The Parent Population of Radio Galaxies and the FRI - FRII Dichotomy [PDF]
We test the hypothesis that radio galaxies are a random subset of otherwise normal elliptical galaxies. Starting with the observed optical luminosity functions for elliptical galaxies, we show that the probability of an elliptical forming a radio source is a continuous, increasing function of optical luminosity, proportional to L squared.

This study examined the health benefits of 3‐O‐butanoylresveratrol (ED4), a monoester derivative of resveratrol butyrate esters. Using a high‐calorie diet model simulation with Chinese sausage, ED4 was tested against changes in physiological indices like body weight (BW), body fat, blood pressure, and SCFA levels (stools and serum) in rats.

The Stellar Kinematics of Elliptical Galaxies [PDF]
The kinematic properties of elliptical galaxies are summarized. New developments are discussed in four areas: (i) the Faber-Jackson relation and the role of second parameters (ii) the luminosity-rotation relation (iii) the figures of elliptical galaxies and (iv) the mass-to-light ratio as a function of radius.

ArtProtect: Blockchain and NFC‐based anti‐counterfeit system for physical art
An anti‐counterfeiting system for physical art based on Ethereum blockchain and near‐field communication technology is proposed and implemented. The system leverages the use of Ethereum smart contracts and inter‐planetary file system to store artworks’ certificate of authenticity, and display them in a mobile app called ArtProtect.

Dynamical Models of Elliptical Galaxies [PDF]
Self-consistent dynamical models of elliptical galaxies have been constructed using a modification of the Prendergast-Tomer algorithm. They reproduce many of the observed properties of elliptical galaxies.

Automatic Detection of Galaxy Type From Datasets of Galaxies Image Based on Image Retrieval Approach
This paper presents a new approach for the automatic detection of galaxy morphology from datasets based on an image-retrieval approach. Currently, there are several classification methods proposed to detect galaxy types within an image.

Central Illustration: The role of multimodality imaging for transcatheter tricuspid valve interventions (TTVI): echocardiography is used for the evaluation of the severity and mechanism of tricuspid regurgitation (TR), for the assessment of the pulmonary pressure and right ventricular (RV) function and for anatomical feasibility for transcatheter ...

We have recently shown that the 3-parameter density-profile model from Prugniel & Simien provides a better fit to simulated, galaxy- and cluster-sized, dark matter halos than an NFW-like model with arbitrary inner profile slope gamma (Paper I).

Causal Discovery in Astrophysics: Unraveling Supermassive Black Hole and Galaxy Coevolution
Correlation does not imply causation, but patterns of statistical association between variables can be exploited to infer a causal structure (even with purely observational data) with the burgeoning field of causal discovery.
