Myocardial performance index estimation by using noninvasive devices
Patent published on the 2026-05-21 in US under Ref US20260137351 by STANCIU SILVIU MARCEL [RO] (Evdochim Lucian [ro], Semenescu Augustin [ro], Vidu Ruxandra [us], Stanciu Silviu Marcel [ro])
Abstract: A physiological signal processing method and apparatus are disclosed. The method involves extracting key waveform markers such as aspiration wave (ASW), diastolic point (DIA), systolic point (SYS), tidal wave (TDW) and dicrotic wave (DCW), which are associated with blood flow perturbations during blood circulation. These perturbations occurring within the systemic circulation originate from the heart s periodic mechanical activity, particularly from the left ventricle and right atrium. The extra[...]
Our summary: This method extracts key waveform markers from physiological signals to estimate parameters related to heart function. It computes the myocardial performance index by analyzing isovolumic contraction time, left ventricular ejection time, and isovolumic relaxation time. The results are validated against real intervals to ensure accuracy and provide insights into cardiac performance.

Investigating the temporal dynamics and modeling of mid-level feature representations in humans
Published on 2026-04-27 by @MIT
Abstract: AbstractVisual perception unfolds through a hierarchy of transformations, beginning with the extraction of low-level features, such as edges, and culminating in the representation of high-level features such as object categories. While the processing of low- and high-level features is well studied, the intermediate transformations, that is, mid-level features, remain poorly understood. Here, we introduce a stimulus set of naturalistic 3D-rendered images and videos with ground-truth annotations f[...]
Our summary: This study investigates mid-level feature representations in visual perception using 3D-rendered images and videos. It identifies the processing time of these features in the brain through EEG responses. The results suggest mid-level features connect sensory and semantic processing, and CNNs can model this processing order.

Abstract: AbstractFunctional ultrasound imaging (fUSI) is a promising tool for studying brain activity in awake and behaving animals, offering insights into neural dynamics that are more naturalistic than those obtained under anesthesia. However, motion artifacts pose a significant challenge, introducing biases that can compromise the integrity of the data. This study provides a comprehensive evaluation and benchmarking of strategies for detecting and removing motion artifacts in transcranial fUSI acquisi[...]
