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 ...

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.

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

open access: yesThe 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).

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.

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

open access: yesSoftware: 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

open access: yesAstronomische 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]

open access: yes, 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 ...

The rise of single‐cell proteomics

open access: yesAnalytical Science Advances, Volume 2, Issue 3-4, Page 84-94, April 2021., 2021
Abstract Mass spectrometry‐based proteomics comprehensively defines proteome expression patterns in thousands of cells majorly contributing to our current understanding of many biological processes. More recently, single‐cell transcriptome and genome studies, however, have demonstrated overwhelming heterogeneity of tissues and cellular subpopulations ...

Nanoscale confinement of energy deposition in glass by double ultrafast Bessel pulses

open access: yesNanophotonics, Volume 10, Issue 3, Page 1089-1097, February 2021., 2021
Abstract Ultrafast laser pulses spatially shaped as Bessel beams in dielectrics create high aspect ratio plasma channels whose relaxation can lead to the formation of nanochannels. We report a strong enhancement of the nanochannel drilling efficiency with illumination by double pulses separated by a delay between 10 and 500 ps.
