Method for cleaning piping systems

Patent published on the 2026-05-20 in UA under Ref UA163076U by STATE UNIV UZHHOROD NATIONAL UNIV [UA] (Zhyhuts Yurii Yuriiovych [ua], Skubenych Kateryna Vasylivna [ua])

Abstract: Method for cleaning piping systems involves the use of a viscoelastic cleaning piston made of a highly elastic material. A container of solvent is placed inside the piston body, and a capsule is located in the piston cap; upon contact with an obstruction such as a valve, gate valve, vent, and heavy blockage, the elastic shell of the container is ruptured, causing not only the blockage but also the viscoelastic piston body itself to dissolve, transforming it into a liquid consistency that is expe[...]


Our summary: The method utilizes a viscoelastic cleaning piston to clear obstructions in piping systems. A solvent is contained within the piston, which ruptures upon contact with blockages. The process dissolves both the blockage and the piston, expelling the material under pressure.

A cross-modal method for indexing cortical lamination

Published on 2026-04-21 by @MIT

Abstract: AbstractIntracortical microstructure profiling represents a powerful, scalable approach for investigating the laminar organisation of the human cortex on both in-vivo and post-mortem datasets. Building upon a long tradition of histological analysis, this method leverages surface-based intracortical sampling to generate profiles of tissue properties across cortical depths. The present work outlines a standardised workflow for intracortical microstructural profiling, newly packaged as the open-sou[...]


Our summary: This study presents a cross-modal method for indexing cortical lamination using intracortical microstructure profiling. The open-source toolbox “CortPro” enables standardized workflows for analyzing tissue properties across cortical depths. Results show the robustness of intracortical profiles in capturing laminar differentiation and their reliability across different studies.

Capabilities and biophysical challenges at clinical 7T scanners

Published on 2026-04-09 by @MIT

Abstract: AbstractSub-millimeter resolution functional magnetic resonance imaging (fMRI) at ultra-high field (≥ 7T) has offered an unprecedented opportunity to probe mesoscopic computations at a columnar or laminar level. However, its application has been primarily restricted to the neocortex. Inferior brain regions, particularly the hippocampus (HC), are challenging targets for laminar fMRI. Recent developments in acquisition methods have shown the feasibility of laminar recordings in the HC using grad[...]


Our summary: This study explores the capabilities of 7T MRI for laminar fMRI in the hippocampus. It demonstrates the optimization of VASO to reduce venous bias and improve signal quality. The findings support the use of advanced acquisition methods to investigate memory retrieval mechanisms at a submillimeter resolution.
