ACME: A Tool to Improve Configuration Memory Fault Injection in SRAM-Based FPGAs

IEEE Access, 2019
Circuits in harsh environments, as space, tend to suffer severe problems caused by radiation. In this scenario, where the behavior of the system can be jeopardized, it is critical to produce fault tolerant circuits that can operate correctly.

Designing Asymmetric Memristive Behavior in Proton Mixed Conductors for Neuromorphic Applications

Advanced Functional Materials, EarlyView.
Protonic devices that couple ionic and electronic transport are demonstrated as bioinspired neuromorphic elements. The devices exhibit rubber‐like asymmetric memristive behavior with slow voltage‐driven conductance increase and rapid relaxation, enabling simplified read–write operation.

Threshold-Type Binary Memristor Emulator Circuit

IEEE Access, 2019
A floating memristor emulator composed of off-the-shelf devices is presented to mimic the dynamics of threshold-type binary memristor. The diodes combined with proportional amplifier circuits are used to model the threshold sensitive behavior.

Conductance‐Dependent Photoresponse in a Dynamic SrTiO3 Memristor for Biorealistic Computing

Advanced Functional Materials, EarlyView.
A nanoscale SrTiO3 memristor is shown to exhibit dynamic synaptic behavior through the interaction of local electrical and global optical signals. Its photoresponse depends quantitatively on the conductance state, which evolves and decays over tunable timescales, enabling ultralow‐power, biorealistic learning mechanisms for advanced in‐memory and ...

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4

Advanced Functional Materials, EarlyView.
An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

Copper‐Based Crystalline‐Metallic Glass Composite Thin Films: A Novel Material with Enhanced Strength and Thermally Stable Nanotwins

Advanced Functional Materials, EarlyView.
A Cu‐based crystal‐glass composite with high‐density twins is identified by a fast screening technique using combinatorial sputtering together with XRD and nanoindentation mapping. This bamboo‐like structure demonstrates homogenous plastic flow and retains high strength during in situ high temperature tests, up to 1 GPa at 550°C, owing to those ...

« Peinte par elle-même? »

Arts et Savoirs, 2016
This essay considers what portraits and self-portraits of several women artists can tell us about problems of authorship and artistic identity as well as relationships between female students and their teachers often represented on the paintings.

A Long-Term Study of Young Children's Rapport, Social Emulation, and Language Learning With a Peer-Like Robot Playmate in Preschool

Frontiers in Robotics and AI, 2019
Prior research has demonstrated the importance of children's peers for their learning and development. In particular, peer interaction, especially with more advanced peers, can enhance preschool children's language growth.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Emulating long-term CMIP6 projections of sterodynamic sea-level change using a three-layer energy balance model

Environmental Research Letters
Multi-century projections of sea-level change are crucial for understanding long-term climate impacts. However, projecting ocean dynamic processes affecting sea-level change faces two main challenges: (1) the ocean’s thermal inertia and dynamics can lead
