Accurate Small-Signal Modeling of Digitally Controlled Buck Converters with ADC-PWM Synchronization

Announce Type: replace Abstract: Digital control has become increasingly widespread in modern power electronic converters. When acquiring feedback signals such as the inductor current, synchronizing the analog-to-digital converter (ADC) with the digital pulse-width modulator (DPWM) is commonly employed to accurately track their steady-state average. However, the small-signal implications of such synchronization have not been investigated.

Lossy Microwave Linear Analog Computer (MiLAC) for Future MIMO: Learning-based Architecture Designs for Spectral and Energy Efficiency Maximization

arXiv:2606.02369v1 Announce Type: cross Abstract: Microwave linear analog computers (MiLACs) offer a transformative paradigm for future multiple-input multiple-output (MIMO) systems by shifting complex signal processing into the analog domain, thereby significantly reducing computational complexity, radio-frequency chains, and analog-digital converters, while speeding up computation. However, the practical deployment of MiLACs is severely constrained by the inherent hardware losses of the...

Stability Analysis for Autoregressive Sampling Sets

Announce Type: cross Abstract: Motivated by recent developments in stochastic modeling of clock jitter in Analog-to-Digital Converters (ADCs) as autoregressive processes of order one (AR(1)), we study the density and stability properties of AR(1)-jittered sampling sets for Paley-Wiener signals. We show that, despite having the correct asymptotic density both on average and almost surely, such sets almost surely fail to be stable sampling sets. We complement this negative result with a...

Everyday task may help detect early dementia signs before diagnosis, study finds

A simple writing test could detect cognitive impairment in older individuals before more serious symptoms occur, scientists have discovered. Writing is a complex, brain-heavy workout that requires the mind to process information, organize thoughts and send precise signals to the fingers all at once, according to experts. Because writing draws on so many complex mental functions, researchers believe that small changes in how people write could provide early warning signs for cognitive impairment.

High-bandwidth frequency domain multiplexed readout of transition-edge sensors for neutrinoless double beta decay searches

arXiv:2601.23106v2 Announce Type: replace Abstract: The next-generation of cryogenic neutrinoless double-beta decay experiments require increasingly fast readout in order to improve background discrimination. These experiments, operated as cryogenic calorimeters at $\sim$10 mK, are usually read out by high-impedance neutron transmutation doped (NTD) thermistors, which provide good energy resolution, but are limited by $\sim$1 ms response times. Superconducting detectors, such as...

SINAPSE: A lightweight deep learning framework for accurate and explainable neutron-$\gamma$ discrimination

arXiv:2605.13627v2 Announce Type: replace Abstract: Traditionally, neutron-$\gamma$ discrimination in organic scintillators relies on techniques such as time-of-flight (ToF) selection and pulse-shape discrimination (PSD). However, particle identification through graphical cuts remains challenging in the low-charge regime due to poor signal-to-noise ratios (SNR). In this work, we propose SINAPSE, a lightweight deep learning framework for accurate and explainable neutron-$\gamma$...

Quality-Diversity Search in Sound Generation: Investigating Innovation Engines for Audio Exploration

arXiv:2606.09780v1 Announce Type: new Abstract: This study addresses the challenges composers and sound designers face in creating and refining tools to achieve their musical goals. Using evolutionary processes to promote diversity and foster serendipitous discoveries, we automate the search through uncharted sonic spaces for sound discovery, arguing that diversity-promoting algorithms can bridge the gap between the theoretical realisation and practical accessibility of sounds.
