Geomagnetic core field models and secular variation forecasts for the 13th International Geomagnetic Reference Field (IGRF-13)

open access: yesEarth, Planets and Space, 2020
Observations of the geomagnetic field taken at Earth’s surface and at satellite altitude are combined to construct continuous models of the geomagnetic field and its secular variation from 1957 to 2020.

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 ...

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 ...

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.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

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

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

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.
