Outer Core Stratification From the High Latitude Structure of the Geomagnetic Field

open access: yesFrontiers in Earth Science, 2018
The presence of stable stratification has broad implications for the thermal and compositional state of the outer core, the evolution of Earth's deep interior, and the energetics of the geodynamo.

A Long-lived Lunar Magnetic Field Powered by Convection in the Core and a Basal Magma Ocean

open access: yesThe Planetary Science Journal, 2023
An internally generated magnetic field once existed on the Moon. This field reached high intensities (∼10–100 μ T, perhaps intermittently) from ∼4.3 to 3.6 Gyr ago and then weakened to ≲5 μ T before dissipating by ∼1.9–0.8 Gyr ago.

Objectification Features of Social Exclusion and Social Inclusion Categories in the Russian Language (Exemplified by “Glubinka” and “Glush” Concepts)

open access: yesВестник Волгоградского государственного университета: Серия 2. Языкознание, 2023
The article is devoted to the consideration of the objectification peculiarities of the social exclusion and social inclusion categories in the territorial aspect in the Russian language on the case of the “glubinka” (“hinterland”) and “glush ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Field distribution anomalies and dielectric failure mechanisms associated with core surface defects in liquid-insulated power transformers [PDF]

open access: yesAIP Advances
Core burr defects are latent sources of electric field distortion and insulation degradation in oil-immersed power transformers. To elucidate their physical mechanism and quantitative impact, this study combines finite element analysis and field testing ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Effective Field Theory and the No-Core Shell Model

open access: yesEPJ Web of Conferences, 2010
In finite model space suitable for many-body calculations via the no-core shell model (NCSM), I illustrate the direct application of the effective field theory (EFT) principles to solving the many-body Schrödinger equation. Two different avenues for fixing

A Fundamental Mechanism of Solar Eruption Initiation in a Multipolar Magnetic Field

open access: yesThe Astrophysical Journal, 2023
Recently, we established a fundamental mechanism of solar eruption initiation in which an eruption can be initiated from a bipolar field through magnetic reconnection in the current sheet (CS) that is formed slowly in the core field as driven by ...
