Mitigating sample-interleaving distortion through decorrelated waveform averaging
Patent published on the 2026-06-11 in WO under Ref WO2026123015 by LAWRENCE LIVERMORE NAT SECURITY LLC [US] (Buckley Brandon Walter [us])
Abstract: Methods and systems for optimally detuning the ratio of analog-to-digital (ADC) sample rate and trigger rate during waveform averaging to minimize the deleterious effects from sample interleaving are described. In some examples, the optimal detuning factor is based on the number of ADC cores used and the limited tuning resolution of the clock rates. An example method includes providing, by a clock generation circuit, an analog-to-digital (ADC) clock to a bank of ADCs, and adjusting at least one [...]
Our summary: The content discusses methods to mitigate sample-interleaving distortion through decorrelated waveform averaging. It describes optimizing the ratio of ADC sample rate and trigger rate to minimize distortion effects. The method involves adjusting clock parameters to ensure the frequencies are relatively prime.

Large language models reveal the neural tracking of linguistic context in attended and unattended multi-talker speech
Published on 2026-05-07 by @MIT
Abstract: AbstractLarge language models (LLMs) capture long-range contextual structure in natural language and have recently been shown to align with the human brain’s contextualized linguistic encoding. This makes them a promising computational probe for studying how context-dependent linguistic information is represented during natural speech perception. Speech perception often occurs in multi-talker environments, where attention must dynamically select among competing streams, yet how contextual info[...]
Our summary: Large language models align with human brain encoding of linguistic context. The study explores how attention affects neural tracking of speech in multi-talker environments. Findings indicate that both attended and unattended speech streams contribute to neural predictions based on contextual information.
