Probing the gravitational wave background from cosmic strings with LISA [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
Cosmic string networks offer one of the best prospects for detection of cosmological gravitational waves (GWs). The combined incoherent GW emission of a large number of string loops leads to a stochastic GW background (SGWB), which encodes the properties

Development and preliminary validation of a machine learning system for thyroid dysfunction diagnosis based on routine laboratory tests

Communications Medicine, 2022
Hu et al. develop a machine learning approach for diagnosis of thyroid disorders based on routine clinical laboratory measurements. The approach is tested on data from multiple institutions and can distinguish patients with hyper- or hypothyroidism from ...

Southern Hemisphere Observations of a $10^{18}$eV Cosmic Ray Source Near the Direction of the Galactic Centre [PDF]

, 2000
We report on an analysis of data from the southern hemisphere SUGAR cosmic ray detector. We confirm the existence of an excess of $10^{18}$eV cosmic rays from a direction close to the Galactic Centre, first reported by the AGASA group.

Statistical validation of ionospheric electron density profiles retrievals from GOES geosynchronous satellites

Journal of Space Weather and Space Climate, 2023
In this paper, we discuss a novel retrieval of ionospheric electron density profiles using the Radio Occultation (RO) technique applied to measurements captured by the Global Positioning System (GPS) receivers onboard two Geostationary Operational ...

Ionization in atmospheres of brown dwarfs and extrasolar planets. IV. The effect of cosmic rays [PDF]

, 2013
Cosmic rays provide an important source for free electrons in Earth's atmosphere and also in dense interstellar regions where they produce a prevailing background ionization. We utilize a Monte Carlo cosmic ray transport model for particle energies of 10(

Cosmic String Interpretation of NANOGrav Pulsar Timing Data. [PDF]

Physical Review Letters, 2020
Pulsar timing data used to provide upper limits on a possible stochastic gravitational wave background (SGWB). However, the NANOGrav Collaboration has recently reported strong evidence for a stochastic common-spectrum process, which we interpret as a ...

Design and operation of a 1500-m laser strainmeter installed at an underground site in Kamioka, Japan

Earth, Planets and Space, 2017
A laser strainmeter with a 1500-m baseline was constructed at an underground site in Kamioka, Gifu Prefecture, Japan, and has been operating since August 2016. The laser interferometer measures the change in distance between two retroreflectors housed in
