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

open access: yesEarth 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

Defining Millisecond Pulsars

open access: yesResearch Notes of the AAS, 2023
Abstract Millisecond pulsars (MSP) are an important subclass of rotation powered pulsars (RPP), traditionally defined as those with P s  < 20–30 ms and B s  ≲ 1010 G.

Optical Spectroscopy and Demographics of Redback Millisecond Pulsar Binaries [PDF]

open access: yesAstrophysical Journal, 2018
We present the first optical spectroscopy of five confirmed (or strong candidate) redback millisecond pulsar binaries, obtaining complete radial velocity curves for each companion star.

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

open access: yesAmerican 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 ...

Pulsating in Unison at Optical and X-Ray Energies: Simultaneous High Time Resolution Observations of the Transitional Millisecond Pulsar PSR J1023+0038 [PDF]

open access: yesAstrophysical Journal, 2019
PSR J1023+0038 is the first millisecond pulsar discovered to pulsate in the visible band; such a detection took place when the pulsar was surrounded by an accretion disk and also showed X-ray pulsations.

Structure and stability of differentially rotating compact stellar objects

open access: yesAstronomische 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.

Timing the Pulsations of the Accreting Millisecond Pulsar SAX J1808.4–3658 during Its 2019 Outburst [PDF]

open access: yesAstrophysical Journal, 2019
In this paper we present a coherent timing analysis of the 401 Hz pulsations of the accreting millisecond X-ray pulsar SAX J1808.4–3658 during its 2019 outburst. Using observations collected with the Neutron Star Interior Composition Explorer (NICER), we

Progress and Challenges in Electromechanical Coupling of Radio Telescopes

open access: yesInternational 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

open access: yesAdvanced 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.
