TeV astronomy of millisecond pulsars [PDF]

, 1991
This thesis is concerned with the detection of pulsed TeV γ-rays from millisecond pulsars. These stars appear to include some very efficient producers of high energy particles, but the mechanisms by which they produce TeV γ-rays are still a matter of ...

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 ...

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.

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 ...

Searching For and Timing Millisecond Pulsars

, 2021
Millisecond pulsars are highly magnetised, rapidly rotating stellar remnants, produced in supernovae and later spun up to milisecond periods by companion stars.

The Effect of Irradiation on the Spin of Millisecond Pulsars

The Astrophysical Journal Letters, 2023
A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario.
