Toroidal Magnetic Flux Budget in Mean-field Dynamo Model of Solar Cycles 23 and 24

The Astrophysical Journal
We study the toroidal magnetic flux budget of the axisymmetric part of a data-driven 3D mean-field dynamo model of Solar Cycles 23 and 24. The model simulates the global solar dynamo that includes the effects of the formation and evolution of bipolar ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Kiladze Caldera: A Possible Cryovolcano on Pluto

The Planetary Science Journal
In contrast with regional primarily methane composition, Kiladze and its surroundings exhibit a water-ice spectral signature that carries an ammoniated compound, similar to two other cryovolcanic sites on Pluto.

Influence of Field of View and Bowtie Filtration on Cone Beam Computed Tomography Image Quality and Scatter-to-Primary Ratio

Journal of Medical Physics
Purpose/Aim: The image quality (IQ) of cone-beam computed tomography (CBCT) is often reduced due to X-ray scatter, causing issues such as shading, skin-line artifacts, decreased contrast-to-noise ratio, and inaccurate computed tomography (CT) numbers ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

A Sensitivity Analysis of the Modeling of Polycyclic Aromatic Hydrocarbon Emission in Galaxies

The Astrophysical Journal
We have conducted a sensitivity analysis on the mid-infrared spectral decomposition of galaxies and the modeling of the polycyclic aromatic hydrocarbon (PAH) emission spectrum with the NASA Ames PAH Infrared Spectroscopic Database (PAHdb) to assess the ...

Estimation of horizontal spatial specifications for ideal head-mounted displays in practical conditions

Frontiers in Virtual Reality
This study presents the horizontal spatial specifications required for developing ideal head-mounted displays (HMDs) that provide visual experiences indistinguishable from those obtained without wearing HMDs.

Joint Blind Motion Deblurring and Depth Estimation of Light Field

, 2018
Removing camera motion blur from a single light field is a challenging task since it is highly ill-posed inverse problem. The problem becomes even worse when blur kernel varies spatially due to scene depth variation and high-order camera motion.
