Resonant Chains and the Convergent Migration of Planets in Protoplanetary Disks
The Astronomical JournalAn increasing number of compact planetary systems with multiple planets in a resonant chain have been detected. The resonant chain must be maintained by convergent migration of the planets due to planet–disk interactions if it is formed before the ...

Excitation of planetary inclinations via dynamical bifurcations driven by misaligned disks
Astronomy & AstrophysicsContext. Primordial misalignments between protoplanetary disks and their host stars’ spin axes have been proposed to be important origins of the widespread stellar obliquities observed in exoplanets. Recent works have further revealed nontrivial and rich

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A multifunctional oleylamine‐assisted solvothermal strategy is introduced for coupled lattice and interface repair of S‐LFP cathodes. Benefiting from its strongly coordinating amine groups and long hydrophobic alkyl chains, oleylamine simultaneously acts as an intrinsic reductant, defect‐repair mediator, morphology stabilizer, and carbon/nitrogen ...

Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Visualizing the kinematics of planet formation
, 2020 A stunning range of substructures in the dust of protoplanetary disks is routinely observed across a range of wavelengths. These gaps, rings and spirals are highly indicative of a population of unseen planets, hinting at the possibility of current ...

Mind the Kinematics Simulation of Planet–Disk Interactions: Time Evolution and Numerical Resolution [PDF]
Planet–disk interactions can produce kinematic signatures in protoplanetary disks. While recent observations have detected non-Keplerian gas motions in disks, their origins are still being debated.

Triboelectric nanogenerators for vehicle intelligent cockpits
FlexMat, EarlyView.Converting mechanical stimuli from drivers and vehicle motion into electrical signals, triboelectric nanogenerators provide promising interfaces toward passive, flexible, distributed and intelligent sensing for next‐generation automotive cockpits to support three core functional dimensions: driver state monitoring, vehicle state monitoring, and human ...

The Astrophysical JournalThe Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey imaged 24 debris disks in polarized H -band light, while other programs observed half of these disks in polarized J and/or K 1 bands. Using

Food Safety and Health, EarlyView.The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

Reading between the Rings: Observed Dust Ring Properties as Probes of Planet Masses
The Astrophysical JournalWe hypothesize that dust rings in protoplanetary disks formed by an embedded planet should have properties that reflect the planet’s mass. We use 2D hydrodynamical simulations of planet–disk interactions to investigate this, focusing on planets ranging ...
