Rapid and predictive planet population synthesis model (RAPPS)

Astronomy & Astrophysics
Context. Exoplanet surveys have revealed a large diversity of planetary systems. Explaining the origin of such diversity requires integrated models of planet formation.

Apparent Stellar Wobble by a Planet in a Circumstellar Disk:

, 2007
Astrometric detection of a stellar wobble on the plane of the sky will provide us a next breakthrough in searching extrasolar planets. The Space Interferometry Mission (SIM) is expected to achieve a high-precision astrometry as accurate as 1 as, which

Scaling turbulence drives the general circulation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Late-infall-induced formation of giant planets, multigenerational planetesimals, and disk substructures

Astronomy & Astrophysics
Late infall can replenish the building materials of planets in protoplanetary disks and dramatically alter their structural evolution. The resulting pressure bumps effectively accumulate dust, facilitate grain coagulation, and trigger planetesimal ...

Object‐based deep learning for probabilistic convective‐core nowcasting from satellite data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Convective cores detected from Meteosat infrared imagery are represented as compact physical objects to generate probabilistic nowcasts up to 6 h ahead. A spatio‐temporal transformer models interactions among evolving core populations and produces gridded probability forecasts across the western Sahel.

Multi‐scale flow analysis for scale‐aware urban canopy models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We found that scale‐aware models are necessary when numerical weather prediction models approach hectometric resolution, which is associated with a characteristic length‐scale of morphological heterogeneity. This morphology‐dependent length‐scale indicates that resolved and unresolved heterogeneity are equally important.

Data‐driven emulation of flow‐dependent background‐error variance in variational data assimilation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A machine‐learning approach is developed to emulate flow‐dependent background‐error variance within a variational data assimilation framework. The method reproduces uncertainty information that would normally require a 50‐member ensemble using only five members, while maintaining comparable observation fit and forecast performance.

Biomimetic robots driven by smart materials: Motion forms, stimulation methods and applications

Responsive Materials, EarlyView.
Biomimetic robots enhance adaptability by mimicking biological systems, but rigid materials limit performance. Smart materials with stimuli responsiveness and shape adaptability enable more flexible actuation and improved environmental interaction.

Rational Design Strategies Toward Efficient and Stable Electrocatalysts for Hydrogen Production via Water Electrolysis: A Comprehensive Review

Small, EarlyView.
ABSTRACT Active and stable electrocatalysts are critical for sustainable hydrogen production, particularly for high‐current‐density water electrolysis and specialized applications like seawater splitting. However, most water‐splitting electrocatalysts show limited activity at high current densities and poor long‐term stability, making it difficult to ...

DNA Coordination Engineering of Dual‐Metal Prussian Blue Analogs for Accelerated Zn2+ Storage

Small, EarlyView.
A sustainable DNA‐assisted strategy was developed to regulate the growth of CuMn‐HCF, producing a porous hierarchical structure with abundant active sites. The optimized CuMn‐HCF‐D7 electrode exhibited enhanced Zn2+ storage kinetics, high reversible capacity, and exceptional cycling stability over 30 000 cycles, demonstrating its potential as a durable
