Description and Application of the Surfing Effect

Universe, 2022
The standard technique for very low-frequency gravitational wave detection is mainly based on searching for a specific spatial correlation in the variation of the times of arrival of the radio pulses emitted by millisecond pulsars with respect to a ...

Message in a Bottle—An Update to the Golden Record: 1. Objectives and Key Content of the Message

Earth and Space Science, Volume 10, Issue 12, December 2023., 2023
Abstract In the first part of this series, we delve into the foundational aspects of “Message in a Bottle (MIAB)” (henceforth referred to as MIAB). This study builds upon the legacy of the Voyager Golden Records, launched aboard Voyager 1 and 2 in 1977, which aimed to communicate with intelligent species beyond our world. These records not only offer a

Fit‐Fat Index is better associated with heart rate variability compared to fitness and fatness alone as indicators of cardiometabolic human health

American Journal of Human Biology, Volume 35, Issue 11, November 2023., 2023
Abstract Objectives Cardiorespiratory fitness and fatness indicators have been related to heart rate variability (HRV) parameters. The Fit‐Fat Index (FFI) is a single index combining cardiorespiratory fitness and fatness indicators. To the best of our knowledge, no studies have previously analyzed whether FFI are related to cardiac autonomic nervous ...

Search for the Gravitational-wave Background from Cosmic Strings with the Parkes Pulsar Timing Array Second Data Release

The Astrophysical Journal, 2022
We perform a direct search for an isotropic stochastic gravitational-wave background (SGWB) produced by cosmic strings in the Parkes Pulsar Timing Array (PPTA) Data Release 2 (DR2).

Structure and stability of differentially rotating compact stellar objects

Astronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023
Abstract Depending on the dynamics of a binary neutron star merger, the collision may result in a differentially rotating compact object. Differentially rotating stars can sustain a total mass considerably higher than that of a uniformly rotating star, giving rise to “hypermassive” objects like hypermassive neutron stars.

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.

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.

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 ...

The Galactic Millisecond Pulsar Population [PDF]

, 2012
Among the current sample of over 2000 radio pulsars known primarily in the disk of our Galaxy, millisecond pulsars now number almost 200. Due to the phenomenal success of blind surveys of the Galactic field, and targeted searches of Fermi gamma-ray ...
