THE PECULIARITIES IN O-TYPE GALAXY CLUSTERS

open access: yesOdessa Astronomical Publications, 2017
We present the results of analysis of 2D distribution of galaxies in galaxy cluster fields. The Catalogue of Galaxy Clusters and Groups PF (Panko & Flin) was used as input observational data set.

Environments of galaxies in groups within the supercluster-void network [PDF]

open access: yes, 2012
Majority of all galaxies reside in groups of less than 50 member galaxies. These groups are distributed in various large-scale environments from voids to superclusters. Evolution of galaxies is affected by the environment in which they reside. Our aim is to study the effects that the local group scale and the supercluster scale environment have on ...

Serendipitous Catch of a Giant Jellyfish: An Ionized Nebula around 3C 275.1 with 170 kpc Long Tails

open access: yesThe Astrophysical Journal
3C 275.1 is a blue quasar at z = 0.55522, hosting powerful outflows and residing in a complex environment. We present a serendipitously detected giant nebula surrounding 3C 275.1, which shows morphological features resembling those of objects known as ...

Facilitating learning in immersive virtual reality: Segmentation, summarizing, both or none?

open access: yesJournal of Computer Assisted Learning, Volume 39, Issue 1, Page 218-230, February 2023., 2023
Abstract Introduction This study investigates the effectiveness of the segmentation principle from the cognitive theory of multimedia learning as well as the effectiveness of the generative learning strategy of summarization in immersive virtual reality (IVR) within a sample of preadolescents.

Effects of Quasar Feedback in Galaxy Groups

open access: yes, 2008
We study the effect of quasar feedback on distributions of baryons and properties of intracluster medium in galaxy groups using high-resolution numerical simulations. We use the entropy-conserving Gadget code that includes gas cooling and star formation,

Utility of circulating tumor DNA in secondary liver malignancies: What we know and what is to come

open access: yesJournal of Surgical Oncology, EarlyView.
Abstract Secondary liver malignancies are a serious and challenging global health concern. Secondary metastasis to the liver is most commonly from colorectal cancer that has metastatically spread through splanchnic circulation. Metastatic diseases can portend poor prognosis due to the progressive nature typically found on detection.

Circulating Tumor DNA as a Marker of Recurrence Risk in Stage III Colorectal Cancer: The α‐CORRECT Study

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background and Objectives Identification of colorectal cancer (CRC) patients at high risk of recurrence could be of substantial clinical use. We evaluated the association of ctDNA status, using a tumor‐informed assay, with recurrence‐free survival (RFS). Methods Stage III CRC patients were enrolled between 2016 and 2020.

Some Properties of Galaxy Structures

open access: yesOpen Astronomy, 2011
We analysed some properties of galaxies structures based on the PF catalog of galaxy structures (Panko & Flin 2006) and the Tully NBG catalog (Tully 1988).

Evaluation of Arclight Frugal Smartphone Video Otoscopy

open access: yesThe Laryngoscope, EarlyView.
Frugal innovations are essential in low‐resource settings to provide cost‐effective medical solutions without compromising functionality. The Arclight, which functions as both an ophthalmoscope and an otoscope, is an effective, low‐cost tool for (video) ear examinations in low‐resource settings.
