NO THE HOLMBERG EFFECT FOR GALAXY PAIRS SELECTED FROM THE SDSS DR9 AT Z ≤ 0:06

open access: yesOdessa Astronomical Publications, 2016
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]

open access: yes, 2001
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.

Chinese Sausage Simulates High Calorie–Induced Obesity In Vivo, Identifying the Potential Benefits of Weight Loss and Metabolic Syndrome of Resveratrol Butyrate Monomer Derivatives

open access: yesJournal of Nutrition and Metabolism, Volume 2025, Issue 1, 2025.
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]

open access: yesSymposium - International Astronomical Union, 1987
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

open access: yesIET Blockchain, Volume 4, Issue 4, Page 423-442, December 2024.
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]

open access: yesSymposium - International Astronomical Union, 1975
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

open access: yesScientific Reports, 2017
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.

Multimodality Imaging for Transcatheter Tricuspid Regurgitation Interventions: Novel Approaches to the Forgotten Valve

open access: yesEchocardiography, Volume 41, Issue 12, December 2024.
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 ...

Empirical Models for Dark Matter Halos. III. The Kormendy relation and the log(rho_e)-log(R_e) relation

open access: yes, 2006
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

open access: yesThe Astrophysical Journal
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.
