A Satellite Analysis: Comparing Two Medicanes
AtmosphereMorphological features of the Mediterranean Sea basin have recently been precursors to a significant increase in the formation of extreme events, in relation to climate change effects. It happens very frequently that rotating air masses and the formation

Problems of Astrophysical Turbulent Convection: Thermal convection in a layer without boundaries [PDF]
in Procs 2010 CTR Summer Program, P. Moin (ed.), pp. 475-484,
Stanford University, 2010, 2011 Thermal convection in fluid layers heated from below are usually realized experimentally as well as treated theoretically with fixed boundaries on which conditions for the temperature and the velocity field are prescribed. The thermal and velocity boundary layers attached to the upper and lower boundaries determine to a large extent the properties of ...

Omni‐Directional Assembly of 2D Single‐Crystalline Metal Nanosheets
Advanced Materials, EarlyView.A versatile assembly method is developed to uniformly assemble 2D single‐crystal copper nanosheets (Cu NS) onto substrates with complex shapes via ultrasonication process. This technique leverages cavitation effects to deposit monolayer Cu NS films with minimal overlap.

Atmospheric cooling of freshwater near the temperature of maximum density [PDF]
arXivWe perform three-dimensional direct numerical simulations of surface-driven convection near the temperature of maximum density $\tilde T_{md}$. A dynamic surface boundary condition couples heat flux through the surface to the induced convection, creating a dynamic equilibrium between the surface water temperature and the convection below.

Global regularity for a family of 3D models of the axisymmetric Navier-Stokes equations [PDF]
, 2017 We consider a family of 3D models for the axi-symmetric incompressible Navier-Stokes equations. The models are derived by changing the strength of the convection terms in the axisymmetric Navier-Stokes equations written using a set of transformed ...

Materializing Convection [PDF]
Architecture and Culture, 2019 This essay uses a physical modeling technique from mechanical engineering, the filling box, as a speculative architectural design tool. In the filling box, dyed salt water is injected into acrylic models submerged within a tank of fresh water, simulating the introduction of cold air into a warm environment or, when mirrored, the introduction of warm ...

Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring
Advanced Materials Interfaces, EarlyView.This study demonstrates direct experimental evidence to establish a nonintuitive connection between the motion characteristics of self‐propelled sperm cells and their surface interaction. Simultaneous motion visualization and cantilever‐deflection‐based adhesion characterization reveal that sperm‐cell droplets with higher motility exhibit lower surface

Fabrication of Ultra‐Thick Masks for X‐Ray Phase Contrast Imaging at Higher Energy
Advanced Materials Interfaces, EarlyView.This work shows a fabrication route to 500 µm thick X‐ray masks the thickest ever reported in the literature combining dynamic optimization of etching parameters and superconformal bismuth‐mediated gold filling. Their use in an Edge Illunomination set‐up showed their higher phase sensitivity at higher energies compared to thinner masks, especially for ...
