Progress and Challenges in Electromechanical Coupling of Radio Telescopes

International Journal of Antennas and Propagation, Volume 2022, Issue 1, 2022., 2022
Radio astronomy is a discipline of dynamics and wonders. The vast universe has many secrets to unravel. As one of the important facilities in this discipline, radio telescopes play a key role in collecting astronomical data and unraveling mysteries.

Electrotherapies for Glioblastoma

Advanced Science, Volume 8, Issue 18, September 22, 2021., 2021
Electrotherapy uses electric fields to target various biological mechanisms for therapeutic outcomes. The current state of intermediate frequency electric fields including tumour‐treating fields, and reversible/irreversible electroporation are discussed in both pre‐clinical and clinical models of glioblastoma.

Pulse profiles of millisecond pulsars [PDF]

International Astronomical Union Colloquium, 1996
We present a comparison between the average radio pulse profiles of millisecond pulsars (MSPs) in the field and in globular clusters. Our sample consists of 20 field MSPs and 25 cluster MSPs for which observations exist at 400 - 600 MHz. We find that 6 of the 20 field MSPs, or about 30%, have a comparable interpulse at a phase offset of 180 ±30 ...

Design and evaluation of a scalable Internet of Things backend for smart ports

Software: Practice and Experience, Volume 51, Issue 7, Page 1557-1579, July 2021., 2021
Abstract Internet of Things (IoT) technologies, when adequately integrated, cater for logistics optimisation and operations' environmental impact monitoring, both key aspects for today's EU ports management. This article presents Obelisk, a scalable and multi‐tenant cloud‐based IoT integration platform used in the EU H2020 PortForward project.

Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]

, 2012
We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

An ultraluminous nascent millisecond pulsar [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2015
Abstract If the ultraluminous source (ULX) M82 X-2 sustains its measured spin-up value of $\dot{\nu }= 10^{-10}\,{\rm s^{-2}}$, it will become a millisecond pulsar in less than 105 yr. The observed (isotropic) luminosity of 1040 erg s−1 also supports the notion that the neutron star will spin up to a millisecond period upon accreting ...

Neutron star collisions and gravitational waves

Astronomische Nachrichten, Volume 342, Issue 5, Page 788-798, June 2021., 2021
Abstract The long‐awaited detection of a gravitational wave from the merger of a binary neutron star in August 2017 (GW170817) marked the beginning of the new field of multi‐messenger gravitational wave astronomy. By exploiting the extracted tidal deformations of the two neutron stars from the late inspiral phase of GW170817, it was possible to ...

Giant Pulses in Millisecond Pulsars [PDF]

Symposium - International Astronomical Union, 2004
Giant pulses (GPs), occasional individual pulses with an intensity 100 times the average intensity, have been detected in four pulsars to date. Their origin is not well understood, but studies suggest a connection between the strength of magnetic field at the light cylinder Blc and the existence of GPs. Here, we report on detection of significant Large
