Evading the dust fragmentation barrier with the streaming instability in protoplanetary disks

Astronomy & Astrophysics
Context. The streaming instability (SI) is a leading candidate for reaching solid densities sufficient to trigger the gravitational collapse needed for the formation of planetesimals. However, dust growth barriers appear to impede the ability to assemble

Analog Signal Summation for Reinforcement Learning via Simultaneous Light–Voltage Modulation in a Synaptic Device

Advanced Science, EarlyView.
To overcome limitations of conventional AI hardware, a light‐voltage dual‐modulating synaptic (LVDS) transistor using an IGZO/InAs quantum dot hybrid structure is proposed. LVDS transistor enables analog summation for Dueling Deep Q‐Networks by independently modulating memory via optical and electrical stimuli.

Ionic Highways under Multivariate‐Coupled Strategies: Ultrahigh Power Generation from Industrial Waste Liquors Using Robust COF Membranes

Advanced Science, EarlyView.
This study presents a multivariate‐coupled strategy to fabricate TB‐COF membranes with tunable charge density via uniformly distributed Bpy groups, enabling efficient ion transport and energy harvesting. The robust β‐ketoenamine‐linked structure ensures stability, achieving power outputs of 53.08 W m−2 (pH 4), 190.52 W m−2 (low‐grade heat), and 258.81 ...

Bell Instability–mediated Diffusive Shock Acceleration at Supernova Blast Wave Shock Propagating in the Interstellar Medium

The Astrophysical Journal
Supernova blast wave shock is a very important site of cosmic-ray acceleration. However, the detailed physical process of acceleration, in particular, nonlinear interplay between cosmic-ray streaming and magnetic field amplification, has not been studied

Vapor‐Assisted Catalysis Enables Precise Construction of MOF‐Derived Hierarchical Carbon Nanoarrays for High‐Performance Supercapacitors

Advanced Science, EarlyView.
A remote‐control strategy for catalyst design is unveiled for advanced carbon materials. During pyrolysis, zinc vapor from a physically separate source guides cobalt catalysts to construct a hierarchical carbon nanoarray. This approach prevents structural collapse while directing the dense growth of carbon nanotubes, yielding a material with ...

Neural Information Processing and Time‐Series Prediction with Only Two Dynamical Memristors

Advanced Electronic Materials, EarlyView.
The present study demonstrates how simple circuits with only two memristive devices are utilized to perform high complexity temporal information processing tasks, like neural spike detection in noisy environment, or time‐series prediction. This circuit simplicity is enabled by the dynamical complexity of the memristive devices, i.e.

In Situ Formation of the Cold Classical Kuiper Belt

The Astrophysical Journal
Cold classical Kuiper Belt objects (CCKBOs) are considered first-generation planetesimals that formed 42–47 au from the Sun and have remained untouched since. Formation is thought to proceed by clumping of dust particles in protoplanetary disk gas by the
