Time‐Resolved Magnetization Switching Dynamics Driven by Orbital Torques
Advanced Functional Materials, EarlyView.Du et al. reveal nanosecond magnetization switching driven by orbital currents using time‐resolved Hall detection. The measurements separate domain nucleation from domain wall propagation and show that Joule heating strongly assists switching by lowering energy barriers.

Backward Stochastic PDEs Related to the Utility Maximization Problem [PDF]
We study utility maximization problem for general utility functions using dynamic programming approach. We consider an incomplete financial market model, where the dynamics of asset prices are described by an Rd-valued continuous semimartingale.

Advanced Functional Materials, EarlyView.Ferroelectric domain variants that are energetically equivalent are expected to remain preserved during polarization reversal. However, phase‐field simulations reveal that inclined domain walls in relaxor ferroelectrics can undergo irreversible elimination during alternating current poling through a proximity effect driven by long‐range elastic ...

Modeling Uncertainty of Iran’s Oil by Mean Reverting Stochastic Process [PDF]
Pizhūhishnāmah-i Iqtiṣād-i Inirzhī-i Īrān, 2014 Uncertainty is different from risk. When a variable is having uncertainty, as oil prices where unique characteristics are expected, risk analysis can not explain the behavior of that variable.

Single-cell replication profiling to measure stochastic variation in mammalian replication timing
Nature Communications, 2018 While DNA replication is temporally regulated during S-phase, variation in replication timing is not well understood. Here, the authors measure variation in replication timing using DNA copy number in single mouse ESCs and find stochastic variation to be

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, EarlyView.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...
