Refrigeration bound of heat-producing cylinders by superfluid helium
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019 In this paper we go ahead in our studies on refrigeration of nanosystems by superfluid helium, as an appealing subject for future applications to computers or astronautical precision nanodevices.

Flow Phase Diagram for the Helium Superfluids
, 2004 The flow phase diagram for He II and $^3$He-B is established and discussed based on available experimental data and the theory of Volovik [JETP Letters {\bf{78}} (2003) 553].

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.Abstract Coastal cities face critical challenges in managing ozone pollution because of high population density and complex interactions between urbanization and coastal meteorology. Using New York City (NYC) as a case study, this work examines how urban surfaces influence heatwaves, sea‐breeze circulations, and boundary‐layer dynamics, and how these ...

Electric field screening by a proton counterflow in the pulsar polar cap
, 2004 We propose a new mechanism to screen the electric field in the pulsar polar cap. Previous studies have shown that if an electron beam from the stellar surface is accelerated to energies high enough to create electron-positron pairs, the required electric

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.Abstract Anthropogenic aerosols influence marine cloud properties in coastal regions, but their impacts remain poorly understood due to the complexity of sources and aerosol‐cloud interactions. To investigate how cloud processing affects aerosol composition, in situ measurements of aerosol properties were performed at Mt. Soledad in La Jolla, CA (251 m

Measurement of Turbulence in Superfluid 3He-B
, 2004 The experimental investigation of superfluid turbulence in 3He-B is generally not possible with the techniques which have been developed for 4He-II. We describe a new method by which a transient burst of turbulent vortex expansion can be generated in 3He-

Nonlocal Internal Variable and Superfluid State in Liquid Helium II
MathematicsWe present a model of superfluidity based on the internal variable theory. We consider a two-component fluid endowed with a scalar internal variable whose gradient is the counterflow velocity.

Dissipation Triggers Dynamical Two-Stream Instability
Particles, 2019 Two coupled, interpenetrating fluids suffer instabilities beyond certain critical counterflows. For ideal fluids, an energetic instability occurs at the point where a sound mode inverts its direction due to the counterflow, while dynamical instabilities ...

Velocity Distributions of Tracer Particles in Thermal Counterflow in Superfluid $^4$He
, 2013 Quantum turbulence accompanying thermal counterflow in superfluid $^4$He was recently visualized by the Maryland group, using micron-sized tracer particles of solid hydrogen (J. Phys. Soc. Jpn. {\bf 77}, 111007 (2008)) .
