Particle module of Piernik MHD code [PDF]

open access: yes, 2010
Piernik is a multi-fluid grid magnetohydrodynamic (MHD) code based on the Relaxing Total Variation Diminishing (RTVD) conservative scheme. The original code has been extended by addition of dust described within the particle approximation.

Detection of an exoplanet around the evolved K giant HD 66141

open access: yes, 2012
Aims. We have been carrying out a precise radial velocity (RV) survey for K giants to search for and study the origin of the lowamplitude and long-periodic RV variations. Methods. We present high-resolution RV measurements of the K2 giant HD 66141 from

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane

open access: yesAdvanced Materials, EarlyView.
Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.

The column density towards LMC X-1

open access: yes, 2009
We measure the neutral absorption towards the black hole X-ray binary system LMC X-1 from six archival soft X-ray spectra obtained with the gratings and/or CCD detectors on Chandra, XMM-Newton, and Swift.

Glaphene: A Hybridization of 2D Silica Glass and Graphene

open access: yesAdvanced Materials, EarlyView.
‘Glaphene’, a novel hybrid material combining 2D silica glass and graphene, is synthesized via a scalable liquid precursor‐based vapor‐phase growth. This study reveals interlayer hybridization beyond van der Waals interactions, leading to emergent semiconducting behavior.

Electric‐Field‐Driven Reversal of Ferromagnetism in (110)‐Oriented, Single Phase, Multiferroic Co‐Substituted BiFeO3 Thin Films

open access: yesAdvanced Materials, EarlyView.
Electric‐field‐induced magnetization reversal is a long‐sought‐after achievement in materials engineering for use in next‐generation, ultra‐low power consumption memory devices. This work demonstrates fully electric‐field‐driven switching of the out‐of‐plane component of magnetization in (110)‐oriented Co‐substituted BiFeO3 thin films at room ...

Design of a hybrid NAR-RBFs neural network for nonlinear dusty plasma system

open access: yesAlexandria Engineering Journal, 2020
Robust modeling of a multimodal dynamic system is a challenging and fast-growing area of research. In this study, an integrated bi-modal computing paradigm based on Nonlinear Autoregressive Radial Basis Functions (NAR-RBFs) neural network model, a new ...
