Topological Skyrmion‐Based Spin‐Torque‐Diode Effect in Magnetic Tunnel Junctions

Advanced Electronic Materials, EarlyView.
Electrical excitation and detection of a breathing skyrmion in a nanoscale skyrmion‐based spin‐torque diode at room temperature is achieved. Skyrmions are generated via spin‐transfer torque current induction, and their breathing dynamics are observed through ferromagnetic resonance (FMR) measurements.

Blue straggler stars in galactic open clusters

, 2021
Blue straggler stars (BSS) were originally identified in the color-magnitude diagram (CMD) of the globular cluster M3, where they defined an extension of the cluster main sequence, blueward and above the turnoff (TO). Among the variety of objects that populate stellar clusters, BSS are surely between those still presenting many puzzles to astronomers ...

Hardware‐Software Codesign of 2D Neuromorphic Optoelectronic Device for Dynamic Gesture Recognition

Advanced Intelligent Systems, EarlyView.
Dynamic gesture recognition based on an in‐sensor reservoir and its synaptic behaviors. Dynamic image recognition with in‐sensor function is achieved, leveraging the capabilities of in‐sensor reservoir computing. Such a computing architecture integrates the sensory capabilities of the retina with the computational advantages of the brain, forming an ...

Effects of Rotationally-Induced Mixing in Compact Binary Systems with Low-Mass Secondaries and in Single Solar-Type Stars [PDF]

, 2012
Many population synthesis and stellar evolution studies have addressed the evolution of close binary systems in which the primary is a compact remnant and the secondary is filling its Roche lobe, thus triggering mass transfer.

Design of Compact Liquid Crystal on Silicon Projection Optics Utilizing a Common Freeform Optical Path for Augmented Reality Displays

Advanced Intelligent Systems, EarlyView.
This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.

Mergers of close primordial binaries

, 2005
We study the production of main sequence mergers of tidally-synchronized primordial short-period binaries. The principal ingredients of our calculation are the angular momentum loss rates inferred from the spindown of open cluster stars and the ...

Rapid Discovery of Sequence‐Encoded Magnetically Reconfigurable Microrobots Using Monte Carlo Simulations

Advanced Intelligent Systems, EarlyView.
A Monte Carlo simulation framework is introduced to predict the folding behavior of sequence‐encoded magnetic microrobots, enabling systematic exploration of their design space. By mapping key metrics such as radius of gyration and symmetry, the framework identifies functional sequences and predicts actuation behaviors.
