Neuromorphic Photonic Processing and Memory With Spiking Resonant Tunneling Diode Neurons and Neural Networks

open access: yesAdvanced Intelligent Systems, EarlyView.
This work shows resonant tunneling diode‐based opto‐electronic spiking neurons enabling fast edge detection in time series, a two‐layer photonic spiking neural network for complex classification, and a depth‐tunable photonic spiking memory system. Neuromorphic computing—modeled after the functionality and efficiency of biological neural systems—offers ...

Nonplanar Atomic Layer Deposition (ALD)‐Niobium Oxide (NbOx) Neurons for Oscillatory Neural Network Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents a nonplanar niobium oxide (NbOx) neuron device fabricated using an atomic layer deposition (ALD) method for use in oscillatory neural networks (ONNs). Potentially, such nonplanar geometry allows for high‐density arrays. The desired threshold switching (TS) characteristics are achieved through an interfacial method using a thin ...

Incentive mechanism of foundation model enabled cross-silo federated learning

open access: yesScientific Reports
The integration of foundation models (FMs) into cross-silo federated learning (FL) introduces transformative capabilities but also exacerbates strategic client behaviors, such as knowledge hoarding and free-riding, which degrade global model performance ...

Proactive Robotic Grasp Stability via Tactile Safety Margin Feedback

open access: yesAdvanced Intelligent Systems, EarlyView.
We introduce the tactile safety margin (TSM), defined as the ratio between applied friction force (Ffric) and maximum friction (Fmax) derived from grip force. A bilayer E‐skin with decoupled temperature, strain, and pressure sensing enables real‐time grasp stability monitoring through measured TSM values, allowing robots to proactively adjust grip ...

Forecasting Investment Needs in South Africa's Electricity and Telecom Sectors [PDF]

open access: yes
The paper uses a 52-country panel-data for the period 1980-2002 to estimate demand for electricity and telecom services and, based on these estimates, project investment needs in South Africa through 2010 for two growth scenarios.

Public Expenditure Accounatability in the Telecom Sector [PDF]

open access: yes
The telecom sector has seen much change during the past two decades. At first, it was the opening up of the equipment manufacturing sector, followed by the corporatisation of the government owned entities, Videsh Sanchar Nigam Limited (VSNL) and ...

Metasurfaces and Metadevices for Topological Electromagnetic Waves

open access: yesAdvanced Physics Research, EarlyView.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Dual‐Wavelength Switchable Focusing via a Fabry‐Pérot Resonance‐Enabled Hydrogel Metalens

open access: yesAdvanced Physics Research, EarlyView.
A hydrogel metalens is demonstrated for dual‐wavelength switchable focusing based on Fabry‐Pérot resonance. Under the low relative humidity, the metalens exclusively focuses light with a resonance wavelength of 470 nm and directly reflects light of other wavelengths.
