Interannual Modulation of Kuroshio in the East China Sea Over the Past Three Decades

open access: yesFrontiers in Marine Science, 2022
Previous studies have suggested that westward-migrating mesoscale eddies are a dominant factor that modulate the interannual Kuroshio intensity in the East China Sea (ECS), indicating a close positive correlation between them.

Epipolythiodioxopiperazine‐Based Natural Products: Building Blocks, Biosynthesis and Biological Activities

open access: yesChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Housing sulfur: Certain fungi produce diketopiperazine compounds with a transannular sulfur bridge. These so‐called epipolythiodioxopiperzines are toxic by non‐specifically interacting with intracellular proteins and contribute to fungal pathogenicity. Producer strains serve as bio‐pesticides but also question safety of food fermentation.

Global models of planetary system formation in radiatively-inefficient protoplanetary discs [PDF]

open access: yes, 2011
(Abridged) We present the results of N-body simulations of planetary systems formation in radiatively-inefficient disc models, where positive corotation torques may counter the rapid inward migration of low mass planets driven by Lindblad torques. The aim of this work is to examine the nature of planetary systems that arise from oligarchic growth in ...

Oxygen Doping Enables Tailored Built‐In Electric Fields in FeOCl/g‐C3N4 Heterojunctions for Enhanced Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
Oxygen‐doping modulated g‐C3N4 support enables a strong built‐in electric field (BIEF) in FeOCl‐OCN.This enhanced BIEF induces the rearrangement of Fe(II)/Fe(III) in FeOCl, which subtly improves intermediates adsorption and also reduces the energy barrier of *O production, thereby achieving efficient PMS activation with 1O2 and Fe(IV)= O as the primary

THE SEISMICITY MIGRATION STUDY BASED ON SPACE-TIME DIAGRAMS

open access: yesГеодинамика и тектонофизика, 2015
Seismicity migration is studied by a new method based on space-time diagrams and a combination of cluster and regression analyses. Data from the global and Baikal regional earthquake catalogues are analysed with the application of the specially designed ...

Numerical simulations of type III planetary migration: III. Outward migration of massive planets [PDF]

open access: yes, 2008
We present a numerical study of rapid, so called type III migration for Jupiter-sized planets embedded in a protoplanetary disc. We limit ourselves to the case of outward migration, and study in detail its evolution and physics, concentrating on the structure of the co-rotation and circumplanetary regions, and processes for stopping migration.

Tetrahedral Tilting and Lithium‐Ion Transport in Halide Argyrodites Prepared by Rapid, Microwave‐Assisted Synthesis

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a rapid, microwave‐assisted synthetic method for halide argyrodite solid‐state electrolytes Li6PS5X${\rm Li}_6 {\rm PS}_5X$ (X=$X =$ Cl−${\rm Cl}^-$, Br−${\rm Br}^-$, I−${\rm I}^-$). Microwave synthesis increases S2−${\rm S}^{2-}$/X−$X^-$ site disorder and rotational disorder of the isolated PS43−${{\mathrm{PS}}_{4}}^{3 ...

Application of recent results on the orbital migration of low mass planets: convergence zones [PDF]

open access: yes, 2011
Previous models of the combined growth and migration of protoplanets needed large ad hoc reduction factors for the type I migration rate as found in the isothermal approximation. In order to eliminate these factors, a simple semi-analytical model is presented that incorporates recent results on the migration of low mass planets in non-isothermal disks.

Migration of the outermost objects in planetary systems [PDF]

open access: yesEAS Publications Series, 2010
The outermost bodies of planetary systems embedded in a planetesimal disk migrate much faster than the other planets. The outward migration of such bodies is self-sustained by supplying fresh planetesimals up to the edge of the disk. We study the dynamics of gravitational interactions between an outer planet and massive planetesimals during this ...
