Moist convection and radiative cooling: Dynamical response and scaling
Quarterly Journal of the Royal Meteorological Society, EarlyView.The mechanism that sets the updraught velocities in deep convective clouds is studied here using cloud‐resolving model simulations in radiative–convective equilibrium. We show that, for simulations with vastly different rates of radiative cooling and surface temperatures, the buoyancy in clouds remains remarkably constant (histogram shown here).

Large-Scale Flow Structure in Turbulent Poiseuille Flows at Low-Reynolds Numbers
Journal of Fluid Science and Technology, 2012 Direct numerical simulations of a spectral method are performed to study the turbulent channel flow at the low-Reynolds numbers, where the quasi-laminar and turbulent regions simultaneously appear and form the stripe pattern, which is floated downstream ...

Activatable smart contrast agents for photoacoustic imaging
Smart Molecules, EarlyView.This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Study of Transition to Turbulence in a Supersonic Boundary Layer Using DNS and Transition Prediction
Journal of Fluid Science and Technology, 2007 The current understanding of supersonic boundary layer transition is reviewed in this paper. The material focuses on bypass transition in a plane supersonic boundary layer. Recent advances in DNS and engineering prediction of transition are discussed. It

Integrative Zoology, EarlyView.We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

The effect of upstream disturbance on the angle of sound emission in a supersonic round jet
Journal of Fluid Science and Technology, 2014 The three-dimensional time-dependent compressible Navier-Stokes equations are numerically solved to study acoustic emission mechanisms in a supersonic round jet at high convective Mach numbers. A 5th-order compact upwind algorithm developed by Deng et al.

Tales of Cyberspace and Artificial Intelligence: Diverging Stakeholderships?
Global Policy, EarlyView.ABSTRACT This article traces the evolution of the Internet from the 1990s to the 2020s and compares it with the development of Artificial Intelligence (AI), particularly following the public launch of ChatGPT in late 2022. It identifies both parallels and divergencies between these two overlapping technological domains, focusing on the growing ...

Untangling nutrient co‐regulation of ombrotrophic peatland development
Boreas, EarlyView.Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...
