Lowering the thermal noise barrier in functional brain mapping with magnetic resonance imaging
Nature Communications, 2021 The signal-to-noise ratio is a key consideration when selecting a magnetic resonance imaging protocol. Thermal noise is major issue, especially in high resolution functional images.

Partial Averaging Near a Resonance in Planetary Dynamics [PDF]
, 1999 Following the general numerical analysis of Melita and Woolfson (1996), I showed in a recent paper that a restricted, planar, circular planetary system consisting of Sun, Jupiter and Saturn would be captured in a near (2:1) resonance when one would allow

Nuclear Physics B, 2004 We study the scenario of thermal leptogenesis in which the leptonic asymmetries are resonantly enhanced through the mixing of nearly degenerate heavy Majorana neutrinos that have mass differences comparable to their decay widths. Field-theoretic issues arising from the proper subtraction of real intermediate states from the lepton-number-violating ...

Resonances of rectangular resonators [PDF]
The Journal of the Acoustical Society of America, 1981 We have used variational methods based on the work of Holland and Eernisse to predict the resonant frequencies of rectangular resonators for use in acoustic transducer arrays. We have predicted both the open and short circuited resonances and have compared the theoretical results obtained with a large number of experiments carried out on such ...

Static and dynamic changes of intrinsic brain local connectivity in internet gaming disorder
BMC Psychiatry, 2023 Background Studies have revealed that intrinsic neural activity varies over time. However, the temporal variability of brain local connectivity in internet gaming disorder (IGD) remains unknown. The purpose of this study was to explore the alterations of
