Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation

Advanced Science, EarlyView.
A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

Asynchronous Authentication

Proceedings of the 2024 on ACM SIGSAC Conference on Computer and Communications Security
A myriad of authentication mechanisms embody a continuous evolution from verbal passwords in ancient times to contemporary multi-factor authentication. Nevertheless, digital asset heists and numerous identity theft cases illustrate the urgent need to revisit the fundamentals of user authentication.

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Speaking Practice Outside the Classroom: A Literature Review of Asynchronous Multimedia-based Oral Communication in Language Learning

The EUROCALL Review, 2018
Classroom instruction provides a limited amount of quality speaking practice for language learners. Asynchronous multimedia-based oral communication is one way to provide learners with quality speaking practice outside of class.

Asymptotics of Asynchronicity [PDF]

, 2011
In this article we focus on estimating the quadratic covariation of continuous semimartingales from discrete observations that take place at asynchronous observation times. The Hayashi-Yoshida estimator serves as synchronized realized covolatility for that we give our own distinct illustration based on an iterative synchronization algorithm.

WS2 Optoelectronic Memristive Reservoir Enabling Ultra‐Low‐Power, Multi‐Task, and Environmentally Stable Neuromorphic Computing

Advanced Science, EarlyView.
WS2‐based in‐memory sensing reservoir computing integrates sensing, memory, and computation in one compact device. It achieves ∼94% N‐MNIST, ∼93% eye motion perception, and ∼89% speech recognition with ultra‐low energy (∼25.5 fJ/spike). The system shows stability at 95% humidity, endurance over 1.5M cycles, and supports synaptic plasticity, enabling ...

Asynchronous automata versus asynchronous cellular automata

Theoretical Computer Science, 1994
The investigations of \textit{A. Mazurkiewicz} [Concurrent program schemes and their interpretations, DAIMI-PB-78, Aarhus University (1977)] and \textit{W. Zielonka} [RAIRO Inf. Theor. Appl. 21, 99-135 (1987; Zbl 0623.68055); Lect. Notes Comput. Sci. 38, 278-289 (1989; Zbl 0678.68077)] are continued. It is proved that an asynchronous cellular automaton
