Generalized Nonlinear Bayesian Pulsar Timing with ENTERPRISE

The Astrophysical Journal
We use the Bayesian methods in the ENTERPRISE package to examine the fully general parameterization of pulsar timing models in tandem with noise. We investigate four pulsars, PSRs J1600–3053, J2043+1711, J0740+6620, and J1640+2224, through the lens of ...

The Green Bank North Celestial Cap Survey. VII. 12 New Pulsar Timing Solutions

The Astrophysical Journal, 2023
We present timing solutions for 12 pulsars discovered in the Green Bank North Celestial Cap 350 MHz pulsar survey, including six millisecond pulsars (MSPs), a double neutron star (DNS) system, and a pulsar orbiting a massive white dwarf companion. Timing

Pushchino multibeam pulsar search VI. Method of pulsar timing using bad timed data

A method for pulsar timing based on monitoring data from the 3-th diagramm of the Large Phased Array (LPA LPI) radio telescope is proposed. In our observations, recorders with quartz clock generators were used as local clocks. Such recorders initially had an accuracy and hardware reference to the UTC time scale insufficient for pulsar timing.

Real‐world insights on switching aflibercept dosage for enhanced outcomes in age‐related macular degeneration (RISE‐AMD): Safety data

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate real‐world safety experience with aflibercept 8 mg in a large case series of patients with neovascular age‐related macular degeneration (nAMD). Methods Due to a high proportion of patients on short treatment intervals, patients with nAMD at a Danish tertiary retina clinic were systematically switched to aflibercept 8 mg ...

Detecting gravitational wave memory with pulsar timing [PDF]

, 2012
We compare the detectability of gravitational bursts passing through the solar system with those passing near each millisecond pulsar in an N-pulsar timing array.

Measuring scattering variations in pulsar timing observations: a test of the fidelity of current methods

Monthly Notices of the Royal Astronomical Society
ABSTRACT The turbulent nature of the ionized interstellar medium (IISM) causes dispersion measure (DM) and scattering variations in pulsar timing measurements. To improve precision of gravitational wave measurements, pulsar timing array (PTA) collaborations have begun the use of sophisticated and intricate noise modelling techniques ...

Long‐term passive heat acclimation enhances maximal oxygen consumption via haematological and cardiac adaptation in endurance runners

The Journal of Physiology, EarlyView.
Abstract Figure Legend Endurance‐trained runners completed a 5‐week hot‐water‐immersion (HWI) intervention (≥40°C, 45 min, five sessions per week) and a training‐matched control period in a cross‐over design. HWI induced a 33 g increase in haemoglobin mass (Hbmass) and a 10 mL expansion in left‐ventricular end‐diastolic volume (LVEDV), resulting in a 2.
