In-Sensor Passive Speech Classification with Phononic Metamaterials

Mitigating the energy requirements of artificial intelligence requires novel physical substrates for computation. Phononic metamaterials have vanishingly low power dissipation and hence are a prime candidate for green, always-on computers. However, their u ...

Enhancement-mode Multi-channel AlGaN/GaN Transistors with LiNiO Junction Tri-Gate

Elison de Nazareth Matioli, Luca Nela, Taifang Wang

Multi-channel GaN power device, consisting of stacking multiple two-dimensional-electron-gas (2DEG) channels, has been demonstrated to achieve unprecedented on-state performance while maintaining high breakdown voltage (VBR). However, the large carrier den ...

At the end of scaling: 2D materials for computing and sensing applications

Nicolò Oliva

In the past half-century, the digital revolution completely changed the world we live in and the ways we experience it. Over this period, the underlying force supporting the continuous technological development has been the geometrical scaling of transisto ...

Sleep-wake-driven and circadian contributions to daily rhythms in gene expression and chromatin accessibility in the murine cortex

Felix Naef, Maxime Jan, Jake Yeung, Ioannis Xenarios

The timing and duration of sleep results from the interaction between a homeostatic sleep-wake-driven process and a periodic circadian process, and involves changes in gene regulation and expression. Unraveling the contributions of both processes and their ...

Theory and Practice of Coroutines with Snapshots

Aleksandar Prokopec, Fengyun Liu

While event-driven programming is a widespread model for asynchronous computing, its inherent control flow fragmentation makes event-driven programs notoriously difficult to understand and maintain. Coroutines are a general control flow construct that can ...

Sleep: An Open-Source Python Software for Visualization, Analysis, and Staging of Sleep Data

Christian O'Reilly, Raphaël Vallat

We introduce Sleep, a new Python open-source graphical user interface (GUI) dedicated to visualization, scoring and analyses of sleep data. Among its most prominent features are: (1) Dynamic display of polysomnographic data, spectrogram, hypnogram and topo ...

Cholinergic, Glutamatergic, and GABAergic Neurons of the Pedunculopontine Tegmental Nucleus Have Distinct Effects on Sleep/Wake Behavior in Mice

The pedunculopontine tegmental (PPT) nucleus has long been implicated in the regulation of cortical activity and behavioral states, including rapid eye-movement (REM) sleep. For example, electrical stimulation of the PPT region during sleep leads to rapid ...

Designing Low Power and Durable Digital Blocks Using Shadow Nanoelectromechanical Relays

Paolo Ienne, Hossein Asadi, Sadegh Yazdanshenas

Nanoelectromechanical (NEM) relays are a promising emerging technology that has gained widespread research attention due to its zero leakage current, sharp ON-OFF transitions, and complementary metal-oxide-semiconductor compatibility. As a result, NEM rela ...

Energy versus Data Integrity Trade-Offs in Embedded High-Density Logic Compatible Dynamic Memories

Andreas Peter Burg, Adam Shmuel Teman, Robert Giterman, Pascal Andreas Meinerzhagen, Georgios Karakonstantis

Current variation aware design methodologies, tuned for worst-case scenarios, are becoming increasingly pessimistic from the perspective of power and performance. A good example of such pessimism is setting the refresh rate of DRAMs according to the worst- ...

Power-Gated Differential Logic Style Based on Double-Gate Controllable-Polarity Transistors

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Luca Gaetano Amarù, Jian Zhang

This brief presents a novel power-gating technique for differential cascade voltage switch logic (DCVSL) based on double-gate (DG) controllable-polarity field-effect transistors (FETs). DG controllable-polarity FETs, commonly referred to as ambipolar trans ...
