Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis
… C-tactile (CT) afferents. Aβ afferents signal discriminative aspects of touch, whereas CT afferents are proposed to play a role in affective touch. Using complementary neuroimaging methods with high temporal resolution, we aimed to distinguish between brain responses evoked by Aβ and CT …

Three-dimensional magnetic field sensor in IBM 0.18μm CMOS technology
This work presents a compact three-dimensional Magnetic Field Sensor (MFS) designed in standard Complementary Metal-Oxide-Semiconductor (CMOS) technology. A circular Vertical Hall Device (VHD) for horizontal magnetic field detection and a split- drain Horizontal Hall Device (HHD) for the vertical …

Magnetic Characteristics of Carboniferous Continental Depositional Systems: Implications for the Recognition of Depositional Hiatuses
Quaternary magnetic studies have provided the conceptual framework to bridge magnetic studies into ancient systems. In cases where environmental materials have been subjected to diagenetic alteration two questions come to mind: 1) What part of the magnetic signal is preserved in the rocks; and 2) …

Probing two-dimensional magnetic phenomena with diamond quantum microscopy
… of high-density memory devices based on novel magnetic materials has promising aspects such as un- matched data retention and low power consumption. However, this technology is still in its early stages and requires further development. Two-dimensional van der Waals magnets and antiferromagnets …

Investigation of half-quantized fluxoid states in Sr2RuO4 mesoscopic superconducting rings
… From the measurements of fluctuations of magnetic signal and the signatures of vortex entries, we found no evidence to support broken time-reversal symmetry (TRS) in these crystals. We argue that various scenarios exist to explain the negative result while still assuming the TRS breaking …

Oceanic lithosphere magnetization : marine magnetic investigations of crustal accretion and tectonic processes in mid-ocean ridge environments
The origin of symmetric alternating magnetic polarity stripes on the seafloor is investigated in two marine environments; along the ridge axis of the fast spreading East Pacific Rise (EPR) (9º 25’-9º 55’N) and at Kane Megamullion (KMM) (23º 40’N), near the intersection of the slow-spreading Mid …

Advanced Aeromagnetic Compensation Models for Airborne Magnetic Anomaly Navigation
Using the earth's magnetic anomaly field for navigation of aircraft has shown promise as a viable alternative to the Global Positioning System (GPS) and other navigation systems. An airborne magnetic anomaly navigation (MagNav) system collects real-time magnetic field data and uses predetermined …

Crustal accretion and evolution at slow and ultra-slow spreading mid-ocean ridges
… perturb underlying mantle flow. Off-axis magnetic anomalies are recorded with high fidelity despite the very low spreading rates and the absence of a basaltic upper crust in one area. The lower crust may be the dominant off-axis carrier of the magnetic signal, contrary to traditional …
