Abstract Objectives Acute cerebral ischemia is characterized by several pathological processes evolving during time, which contribute to the final tissue damage. Secondary processes, such as prolonged inflammatory response, impaired mitochondrial function and oxidative stress, are responsible for the progression of brain injury to the peri‐infarct area,

Calibration of Magnetometers with GNSS Receivers and Magnetometer-Aided GNSS Ambiguity Fixing
Magnetometers provide compass information, and are widely used for navigation, orientation and alignment of objects. As magnetometers are affected by sensor biases and eventually by systematic distortions of the Earth magnetic field, a calibration is ...

The adsorption of AsV on akaganeite nanorods was found to provide a magnetic signature. A change in the surface spin order gave rise to a second peak in the zero‐field cooled curve. AsIII adsorption does not provide any change in the magnetic behavior of the sorbent.

QUARTZ MAGNETOMETER-GRADIOMETER
The work is devoted to the description of the design of a magnetometer-gradiometer created on the basis of quartz sensors, which has the ability to carry out synchronous measurements at two points spaced apart in space on a fixed or arbitrarily located "measuring base" ∆L with different distances of these measuring points from each other. The device is

High‐Density and Scalable Graphene Hall Sensor Arrays Through Monolithic CMOS Integration
This work explores strategies to create high‐density arrays of graphene Hall‐effect magnetic field sensors through monolithic integration with silicon CMOS biasing and multiplexing circuitry. High sensor yield and magnetic sensing performance are achieved through careful choices in the custom CMOS chip design and the graphene integration process.
