Domain wall depinning governed by the spin Hall effect

Abstract: Perpendicularly magnetized materials have attracted significant interest owing to their high anisotropy, which gives rise to extremely narrow, nanosized domain walls. As a result, the recently studied current-induced domain wall motion (CIDWM) in these materials promises to enable a new class of data, memory and logic devices1, 2, 3, 4, 5. Here we propose the spin Hall effect as an alternative mechanism for CIDWM. We are able to carefully tune the net spin Hall current in depinning experiments on Pt/Co/Pt nanowires, offering unique control over CIDWM. Furthermore, we determine that the depinning efficiency is intimately related to the internal structure of the domain wall, which we control by the application of small fields along the nanowire. This manifestation of CIDWM offers an attractive degree of freedom for manipulating domain wall motion by charge currents, and sheds light on the existence of contradicting reports on CIDWM in perpendicularly magnetized materials6, 7, 8, 9, 10, 11.

The Implicit Prejudiced Attitudes of Teachers Relations to Teacher Expectations and the Ethnic Achievement Gap

Abstract: Ethnic minority students are at risk for school failure and show a heightened susceptibility to negative teacher expectancy effects. In the present study, whether the prejudiced attitudes of teachers relate to their expectations and the academic achievement of their students is examined. The prejudiced attitudes of 41 elementary school teachers were assessed via self-report and an Implicit Association Test. Teacher expectations and achievement scores for 434 students were obtained. Multilevel analyses showed no relations with the self-report measure of prejudiced attitudes. The implicit measure of teacher prejudiced attitudes, however, was found to explain differing ethnic achievement gap sizes across classrooms via teacher expectations. The results of this study also suggest that the use of implicit attitude measures may be important in educational research.

Post Quantum Cryptography

Abstract: Quantum computers will break today's most popular public-key cryptographic systems, including RSA, DSA, and ECDSA This book introduces the reader to the next generation of cryptographic algorithms, the systems that resist quantum-computer attacks: in particular, post-quantum public-key encryption systems and post-quantum public-key signature systems Leading experts have joined forces for the first time to explain the state of the art in quantum computing, hash-based cryptography, code-based cryptography, lattice-based cryptography, and multivariate cryptography Mathematical foundations and implementation issues are included This book is an essential resource for students and researchers who want to contribute to the field of post-quantum cryptography

Design and experimental evaluation of cooperative adaptive cruise control

Abstract: Road throughput can be increased by driving at small inter-vehicle time gaps. The amplification of velocity disturbances in upstream direction, however, poses limitations to the minimum feasible time gap. String-stable behavior is thus considered an essential requirement for the design of automatic distance control systems, which are needed to allow for safe driving at time gaps well below 1 s. Theoretical analysis reveals that this requirement can be met using wireless inter-vehicle communication to provide real-time information of the preceding vehicle, in addition to the information obtained by common Adaptive Cruise Control (ACC) sensors. In order to validate these theoretical results and to demonstrate the technical feasibility, the resulting control system, known as Cooperative ACC (CACC), is implemented on a test fleet consisting of six passenger vehicles. Experiments clearly show that the practical results match the theoretical analysis, thereby indicating the possibilities for short-distance vehicle following.
