Shift of effective lightning areas during pre to post period of solar cycle minimum of 2008-2009 as determined from Schumann resonance studies at Agra, India

Annals of Geophysics, 2015
Employing a set of 3-component search coil magnetometer, Schumann resonance studies have been in progress at Agra (Geograph. lat. 27.2°N, long. 78°E), India since 01 April, 2007.

A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...

Update on monitoring of magnetic and electromagnetic tectonic signals in Central Italy

Annals of Geophysics, 2007
A network of three absolute magnetometer stations and the geomagnetic observatory of L’Aquila (42°23N, 13°19E) monitors possible seismo- or tectonomagnetic effects in Central Italy, using L’Aquila Observatory as a reference for differentiation.

New Clock Comparison Searches for Lorentz and CPT Violation

, 2000
We present two new measurements constraining Lorentz and CPT violation using the Xe-129 / He-3 Zeeman maser and atomic hydrogen masers. Experimental investigations of Lorentz and CPT symmetry provide important tests of the framework of the standard model

Distinct Resting‐State Connectomes for Face and Scene Perception Predict Individual Task Performance

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
Resting‐state fMRI and MEG functional connectivity reveal that the FFA and PPA anchor distinct spatio‐temporal networks. The strength of this intrinsic architecture shows a double dissociation: FFA‐network connectivity specifically predicts face‐task performance, while PPA‐network connectivity predicts scene‐task performance, linking intrinsic ...

An Improved Experimental Limit on the Electric Dipole Moment of the Neutron [PDF]

, 2006
An experimental search for an electric-dipole moment (EDM) of the neutron has been carried out at the Institut Laue-Langevin (ILL), Grenoble. Spurious signals from magnetic-field fluctuations were reduced to insignificance by the use of a cohabiting ...

Searching for ULF signatures of the cusp: Observations from search coil magnetometers and auroral imagers in Svalbard [PDF]

Journal of Geophysical Research: Space Physics, 2009
Spacecraft traveling through the cusp at a variety of altitudes have consistently found the cusp to be filled with intense, often irregular power in the upper ULF frequency range. Some ground‐based studies have observed narrowband waves in this same frequency range in the vicinity of the cusp foot point, but it has not been possible with magnetometers ...

Effects of Age on Resting‐State Cortical Networks

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
ABSTRACT Understanding how ageing affects brain function remains a central challenge in neuroscience. Electrophysiological brain imaging techniques provide a near‐direct measure of neuronal activity, which is useful for characterising neurophysiological health.

Measurement of the Permanent Electric Dipole Moment of the $^{129}$Xe Atom

, 2019
We report on a new measurement of the CP-violating permanent Electric Dipole Moment (EDM) of the neutral $^{129}$Xe atom. Our experimental approach is based on the detection of the free precession of co-located nuclear spin-polarized $^3$He and $^{129 ...

Noise characterization of an atomic magnetometer at sub-millihertz frequencies [PDF]

, 2015
Noise measurements have been carried out in the LISA bandwidth (0.1 mHz to 100 mHz) to characterize an all-optical atomic magnetometer based on nonlinear magneto-optical rotation.
