An Automated Occultation Network for Gravitational Mapping of the Trans-Neptunian Solar System
The Planetary Science JournalWe explore the potential of an array of ${ \mathcal O }(100)$ small fixed telescopes, aligned along a meridian and automated to measure millions of occultations of Gaia stars by minor planets, to constrain gravitational signatures from a “Planet X” mass ...

Advanced Science, EarlyView.A self‐supporting nanoporous multicomponent CoCuMoNi catalyst is synthesized. Through the synergistic effect of multiphase interfaces, built‐in electric fields, and defect engineering, the binding energy of key reaction intermediates in hydrogen evolution reaction (HER)/oxygen evolution reaction (OER) is modulated, achieving high activity and stability

Recent decrease in inner‐core rain rate of tropical cyclones over the western North Pacific
Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022 The decreasing trend in inner‐core rain rate of tropical cyclones over the western North Pacific. Abstract The tendency in tropical cyclone (TC) rainfall is of great concern due to its remarkable contribution to global precipitation and extreme rainfall events.

Packaging Metal Atomic Clusters for Universal and Robust Protection through Cluster Beam Process
Advanced Science, EarlyView.Gas‐phase‐aggregated metal clusters are packaged and well‐protected in poly(methyl methacrylate) (PMMA) through controlled beam implantation. The packaged precise clusters show robust protection against oxidation and agglomeration. This protection also demonstrates universality, as it successfully protects metal clusters composed of various elements ...

Upper‐level midlatitude troughs in boreal winter have an amplified low‐latitude linkage over Africa
Atmospheric Science Letters, Volume 24, Issue 1, January 2023., 2023 Composite mean anomaly of 850‐hPa temperature at 10–15° N 2 days after the strongest midlatitude upper‐level trough days. The troughs are located at the longitude shown on the x‐axis, and the temperature is measured 16.5° longitude downstream (east) of the trough. Black dots indicate statistical significance.

Configuration and Charge Dynamics of Defect‐Cluster‐Dipoles in CaTiO3 for Enhanced Permittivity
Advanced Electronic Materials, EarlyView.In La‐doped CaTiO3, the clustering of La ion and Ca vacancies is clearly observed and the configuration of such defect‐cluster is validated. Combining photoelctronic and dielectric spectroscopy enables the dielectric relaxation process with the charge transfer routes.

Observational tests of 4D double field theory
European Physical Journal C: Particles and FieldsAlthough General Relativity (GR) is a very successful theory of gravity, it cannot explain every observational phenomenon. People have tried many kinds of modified gravity theory to explain these phenomena which GR cannot explain very well, such as ...
