In Memory of Alexei Pokrovskii: Systems with Hysteresis & Murphys, 10 Years Later

ADHD: 10 Years Later

Estimates of children struggling with attention-deficit/hyperactivity disorder (ADHD) vary, but the Centers for Disease Control puts the number at a stunningly high 25 percent. Whatever the number, ADHD affects too many children at school, at home, and with their peers, and often persists into adulthood. The cause is as yet unknown, although genetic factors and their interaction with the enviro...

iPS Cells 10 Years Later

In 2006, Takahashi and Yamanaka reported the breakthrough discovery of induction of pluripotent stem cells from fibroblasts by a combination of defined factors. Ten years later, Cell editor João Monteiro brings together Shinya Yamanaka and Hans Schöler, one the original reviewers of the landmark study, to revisit the history behind the paper and its long-lasting legacy.

Security patterns: 10 years later

Reusing time-tested solutions rather than inventing ad-hoc quick fixes is a wellknown security principle. Architectural and design patterns represent proven techniques to package knowledge from software engineering experts in a reusable format. More importantly, the solution proposed by a pattern is known to be sound because it is time-tested—its strengths, weaknesses and possible drawbacks are...

Hysteresis Modeling of Magnetic Shape Memory Alloy Actuator Based on Krasnosel'skii-Pokrovskii Model

As a new type of intelligent material, magnetically shape memory alloy (MSMA) has a good performance in its applications in the actuator manufacturing. Compared with traditional actuators, MSMA actuator has the advantages as fast response and large deformation; however, the hysteresis nonlinearity of the MSMA actuator restricts its further improving of control precision. In this paper, an impro...
