Magnetars: Time Evolution, Superfluid Properties, and Mechanism of Magnetic Field Decay [PDF]

, 2004
We calculate the coupled thermal evolution and magnetic field decay in relativistic model neutron stars threaded by superstrong magnetic fields (B > 10^{15} G).

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

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

Frontiers 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.

Banded transformer cores [PDF]

, 1974
A banded transformer core formed by positioning a pair of mated, similar core halves on a supporting pedestal. The core halves are encircled with a strap, selectively applying tension whereby a compressive force is applied to the core edge for reducing ...

Magnetic processes in a collapsing dense core. I Accretion and Ejection

, 2007
Abridged. It is important for the star formation process to understand the collapse of a prestellar dense core. We investigate the effect of the magnetic field during the first collapse up to the formation of the firstcore, focusing particularly on the ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

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

AIP 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)

Вестник 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 ...

Criterion for transformation of transverse domain wall to vortex or antivortex wall in soft magnetic thin-film nanostripes [PDF]

, 2008
We report on the criterion for the dynamic transformation of the internal structure of moving domain walls (DWs) in soft magnetic thin-film nanostripes above the Walker threshold field, Hw. In order for the process of transformation from transverse wall (

Magnetic Fields in Quasar Cores. II.

The Astrophysical Journal, 2000
Multi-frequency polarimetry with the Very Long Baseline Array (VLBA) telescope has revealed absolute Faraday Rotation Measures (RMs) in excess of 1000 rad/m/m in the central regions of 7 out of 8 strong quasars studied (e.g., 3C 273, 3C 279, 3C 395). Beyond a projected distance of ~20 pc, however, the jets are found to have |RM| < 100 rad/m/m.
