H‐current modulation of cortical Up and Down states

The Journal of Physiology, Volume 603, Issue 8, Page 2409-2424, 15 April 2025.
Abstract figure legend H‐current is an ionic current mediated by HCN (hyperpolarization‐activated cyclic nucleotide‐gated) channels, which are the target of some neurotransmitters. We investigated the role of h‐current in shaping cortical slow waves, which consist of Up and Down states (periods of neuronal activity and silence respectively).

Permanent Deformation of Thermoplastic Polyurethane in the Solid‐State Rolling Process

Advances in Polymer Technology, Volume 2025, Issue 1, 2025.
The findings suggest that rolling is a potentially effective technique for commercial applications in industries requiring high‐performance polymer films. The solid‐state rolling process is well‐established for semicrystalline and amorphous polymers, but its application to segmented, two‐phase polymers like thermoplastic polyurethane (TPU) which ...

Generation potential of kerogen of the Bazhenov formation and possibility of its implementation

, 2017
Bazhenov formation is one of the most well-known and potentially productive Russian oil shale formations. However, conventional methods often do not provide oil flow rate from the formation.

The Silent VOICE—Searching for Geochemical Markers to Track the Impact of Late Jurassic Rift Tectonics

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 10, October 2024.
Abstract A causal mechanism for the Volgian Isotopic Carbon Excursion (VOICE) remains enigmatic. Elemental geochemical profiles of the Deer Bay Formation, Sverdrup Basin, Arctic Canada that record the VOICE and contemporaneous strata are herein examined to provide insight into depositional environments during Late Jurassic‐Early Cretaceous time.

The regularities of the distribution of siliceous mudstones and “coccolith” member of the Bazhenov Formation

, 2017
Based on results of comprehensive lithological and geochemical analysis, we have established the regularities of the spatial distribution of major rock-forming components of the Bazhenov Formation in the West Siberian Basin (WSB), namely, siliceous ...

Comparing cognition across major transitions using the hierarchy of formal automata

WIREs Cognitive Science, Volume 15, Issue 4, July/August 2024.
The idea of a major cognitive transition can be modeled in terms of where a system's effective computational architecture falls on the well‐studied hierarchy of formal automata (HFA). Abstract The evolution of cognition can be understood in terms of a few major transitions—changes in the computational architecture of nervous systems that changed what ...

Bazhenov fm unconventional reservoir 3D geological modeling methodology

, 2016
The Bazhenov Formation has been studied for more than 50 years, but its petroleum potential, optimal STOIIP or resource estimation approaches, the methodology used to select a reservoir, determine its properties are still unclear.

Evidence of carbonate rocks formation on geochemical barriers in black shale on the example of the Bazhenov formation of the Western Siberia

, 2019
A comprehensive lithological-geochemical study of rocks of the Upper Jurassic-Lower Cretaceous blackshale Bazhenov formation showed that most of its carbonatized interlayers to the boundaries of packs of different composition differing in carbonate ...
