Gravitational wave radiometry: Mapping a stochastic gravitational wave background [PDF]

open access: yes, 2008
The problem of the detection and mapping of a stochastic gravitational wave background (SGWB), either of cosmological or astrophysical origin, bears a strong semblance to the analysis of CMB anisotropy and polarization.

Closed-loop deep brain stimulation based on a stream-clustering system [PDF]

open access: yes, 2019
Idiopathic Parkinsons disease (PD) is currently the second most important neurodegenerative disease in incidence. Deep brain stimulation (DBS) constitutes a successful and necessary therapy; however, the continuous stimulation it provides can be ...

What Should the International Non-Proliferation Regime Look Like Today and Over the Next 10 to 20 Years?

open access: yesJournal for Peace and Nuclear Disarmament
Frustration over the lack of progress in nuclear disarmament under the Nuclear Non-Proliferation Treaty (NPT) led to the creation of the Treaty on the Prohibition of Nuclear Weapons (TPNW). On the other hand, there is criticism that the TPNW has fostered

Predictability of the Onset of the Rainy Season Across Thailand: Mechanisms and Non‐Stationary Behaviour

open access: yesInternational Journal of Climatology, Volume 45, Issue 9, July 2025.
The onset of the rain season in Thailand in the late April–early May is highly predictable from ending ENSO events. The predictability is highly non‐stationary from 1950 due to subtle changes during warm ENSO events, which last longer and are more intense from 1980 onward.

Rate of Convergence Towards Semi-Relativistic Hartree Dynamics

open access: yes, 2013
We consider the semi-relativistic system of $N$ gravitating Bosons with gravitation constant $G$. The time evolution of the system is described by the relativistic dispersion law, and we assume the mean-field scaling of the interaction where $N \to ...
