Respiratory disease assessment device and respiratory disease assessment method
Patent published on the 2026-05-21 in WO under Ref WO2026105474 by OMRON HEALTHCARE CO LTD [JP] (Inoue Hiromasa [jp], Kubota Shingo [jp], Hashino Kenji [jp], Ebisu Chiaki [jp])
Abstract: In the present invention, a photoplethysmography signal corresponding to the pulse of a subject is acquired in time series by a sensor (S101). On the basis of a pulse waveform represented by the time-series photoplethysmography signal, a feature amount including at least the interval, amplitude, and baseline of the pulse waveform is extracted for each beat (S104). On the basis of the pulse waveform, a respiratory period corresponding to each respiration of the subject is identified (S107). The r[...]
Our summary: The device acquires a photoplethysmography signal to analyze the pulse of a subject. It extracts features from the pulse waveform to identify respiratory periods and calculates variations in these features. Finally, it assesses the exacerbation severity of the respiratory disease based on the calculated variations.

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.
