Spin and charge drift-diffusion in ultra-scaled MRAM cells

Scientific Reports, 2022
Designing advanced single-digit shape-anisotropy MRAM cells requires an accurate evaluation of spin currents and torques in magnetic tunnel junctions (MTJs) with elongated free and reference layers.

Comparison of Unilateral Middle Cerebral Artery and Bilateral Middle Cerebral Artery Monitoring for Right-to-Left Shunt Detection by Contrast-Enhanced Transcranial Doppler

Frontiers in Neurology, 2022
IntroductionContrast-enhanced transcranial Doppler (c-TCD) is a noninvasive test with high sensitivity for the detection of a right-to-left shunt (RLS). Currently, there are no reports on the outcomes of unilateral versus bilateral middle cerebral artery

MIMO-OTFS in High-Doppler Fading Channels: Signal Detection and Channel Estimation [PDF]

Global Communications Conference, 2018
Orthogonal time frequency space (OTFS) modulation is a recently introduced multiplexing technique designed in the 2-dimensional (2D) delay-Doppler domain suited for high-Doppler fading channels.

Channel Estimation and Equalization for CP-OFDM-based OTFS in Fractional Doppler Channels [PDF]

2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2020
Orthogonal time frequency and space (OTFS) modulation is a promising technology that satisfies high-Doppler requirements for future mobile systems. OTFS encodes information symbols and pilot symbols into the two-dimensional (2D) delay-Doppler (DD) domain.

Self-related processing and deactivation of cortical midline regions in disorders of consciousness

Frontiers in Human Neuroscience, 2013
Self-related stimuli activate anterior parts of cortical midline regions, which normally show task-induced deactivation. Deactivation in medial posterior and frontal regions is associated with the ability to focus attention on the demands of the task ...
