The hitting time expression Equation 14 involves three different types of contributions: a one-body term that depends on the destination node, C 1 jj Pn k1⁄41 dk; a two-body term that depends on the initial and final nodes, C 1 ji Pn k1⁄41 dk; and a series of three-body terms that depend on intermediate nodes, in addition to the two end points, Pn k1⁄41 C 1 ki C 1 kj dk. Derivation of Equatio...

The Australian NWC (North West Cape) signal transmitter is known to strongly interfere with the topside ionosphere. We analyze 456 conjunctions between Swarm A, B and NWC, in addition 58 NorSat-1 NWC. in-situ measurements provided by these satellites include 16 Hz Advanced Plasma Density data set, novel 1,000 plasma density from m-NLP system aboard NorSat-1. subject a detailed PSD analysis subs...

Recent studies have demonstrated large amplitude spontaneous fluctuations in functional-MRI (fMRI) signals in humans in the resting state. Importantly, these spontaneous fluctuations in blood-oxygenation-level-dependent (BOLD) signal are often synchronized over distant parts of the brain, a phenomenon termed functional-connectivity. Functional-connectivity is widely assumed to reflect interregi...

An empirical fetch-limited ocean wave spectrum has been combined with an acoustic ray-based model to predict the acoustic signal time-angle fluctuations induced by sea surface roughness. Rough sea surface realizations are generated and used as sea surface boundaries with the acoustic model. To validate this model, results are compared against experimental data collected in a fetch limited regio...

We present a passive sonar tracking algorithm that utilizes variations in the amplitude of the signal received from a source in motion. The approach is model-based in that it employs an acoustic propagation computer program, and Bayesian in that prior knowledge is used to compute a posterior probability distribution function from which the target location is estimated. The algorithm is designed...

The development of high-field magnetic resonance imaging (MRI) systems has allowed for critical improvements in image signal-to-noise ratio (SNR), potentially leading to higher sensitivity and spatial resolution for functional MRI (fMRI) techniques. However, recent studies have shown that these potential advantages become significantly compromised by increased signal fluctuations arising from c...
