Domain-wall skyrmion chain and domain-wall bimerons in chiral magnets

Yuki Amari, Calum Ross, and Muneto Nitta We construct domain-wall skyrmion chains and domain-wall bimerons in chiral magnets with an out-of-plane easy-axis anisotropy and without a Zeeman term coupling to a magnetic field. Domain-wall skyrmions are skyrmions trapped inside a domain wall, and they are present in the ferromagnetic (FM) phase of …

Searching for New Nontrivial Choreographies for the Planar Three-Body Problem

Hristov, I., Hristova, R., Puzynin, I., Puzynina, T., Sharipov, Z., Tukhliev, Z. A specialized numerical search for new nontrivial choreographies for the planar three-body problem is made. With only three known so far nontrivial choreographies, we found 161 new ones. The linear stability of all found orbits is investigated by …

Theoretical predictions of properties and adsorption behaviour of a superheavy element Ts and its lighter homolog At, and of their various gas-phase compounds, on hydroxylated quartz surfaces from periodic DFT calculations

Miroslav Iliaš, Valeria Pershina Adsorption energies, Eads, of a superheavy element Ts and its lighter homolog At, as well as of their various oxides, hydrides, and (oxy)hydroxides on hydroxylated quartz surfaces are calculated using a periodic density functional theory implemented in the AMS BAND software. It was shown that elemental At …

Generating and grading 34 optimised norm-conserving Vanderbilt pseudopotentials for actinides and super-heavy elements in the PseudoDojo

Christian Tantardini, Miroslav Iliaš, Matteo Giantomassi, Alexander G. Kvashnin, Valeria Pershina, Xavier Gonze In the last decades, material discovery has been a very active research field driven by the need to find new materials for many different applications. This has also included materials with heavy elements, beyond the stable isotopes of lead, …

Impact of mutations on the stability of SARS-CoV-2 nucleocapsid protein structure

Nelli Muradyan, Vahram Arakelov, Arsen Sargsyan, Adrine Paronyan, Grigor Arakelov, Karen Nazaryan The nucleocapsid (N) protein of SARS-CoV-2 is known to participate in various host cellular processes, including interferon inhibition, RNA interference, apoptosis, and regulation of virus life cycles. Additionally, it has potential as a diagnostic antigen and/or immunogen. Our research focuses on examining structural …

In Silico Study of Pyrin and 14-3-3 Protein Modulation During FMF and PAAND

Adrine Paronyan, Nelli Muradyan, Arsen Sargsyan, Vahram Arakelov, Grigor Arakelov, Karen Nazaryan Familial Mediterranean fever (FMF) is a genetically determined disease transmitted through autosomal recessive inheritance. Recently, a rare but similar disease to FMF, pyrin-associated autoinflammation with neutrophilic dermatosis (PAAND), has been discovered. PAAND is inherited dominantly and is characterized by neutrophilic dermatosis and recurrent …

(РАУ, ЕрГУ, ИППФ, Армения), Витя Варданян (Институт молекулярной биологии НАН РА) В качестве модельной системы рассматривался белок представленный в pdb-файле 8SIN (рис. 1), состоящий из четырех мономерных белков. Рис. 1. Белок KCNQ1 в «нижней» конформации Для изучения его конформационных изменений под действием внешнего электрического поля была создана система, …

Enhanced discharge robustness of large-scale resistive WEM detectors with diamond-like carbon anode

V. Bayev, K. Afanaciev, S. Movchan, A. Kashchuk, O. Levitskaya, V. Akulich and V. Konovalov A prototype of the large-scale resistive WEM (Well Electron Multiplier) detector with enhanced discharge robustness was developed, produced and tested. The WEM detector is composed of a perforated board (500 µm thick with drilled holes …

Electronic Properties of Pristine and Doped Graphitic Germanium Carbide Nanomeshes

Majed Abdel Salam Nashaat Moharram AbdelGhani (Sarah Gamal, M. Nashaat, Lobna Salah, Nageh Allam and Ahmed A Maarouf) Graphitic germanium carbide (g-GeC) is a novel material that has recently aroused much interest. Porous g-GeC can be fabricated by forming a lattice of pores in pristine g-GeC. In this work, we systematically …
