Subharmonic spectroscopy of ultrasound contrast agents
We have investigated the subharmonic vibration of BR14 (Bracco Research S.A., Geneva, Switzerland) contrast agent microbubbles between 8-11 MHz. The response of the bubbles is recorded optically with the ultrafast recording camera (Brandaris 128) at ...

Integrability of superharmonic functions and subharmonic functions [PDF]
We apply the coarea formula to obtain integrability of superharmonic functions and nonintegrability of subharmonic functions. The results involve the Green function. For a certain domain, say Lipschitz domain, we estimate the Green function and restate the results in terms of the distance from the boundary.

Subextension and approximation of $m$-subharmonic functions with given boundary values [PDF]
In this paper we establish a result on subextension of $m$-subharmonic functions in the class $\mathcal{F}_m(\Omega,f)$ without changing the hessian measures.

A Symmetrical Property of the Spectral Trace in Banach Algebras
Our aim in this paper is to extend a symmetrical property of the trace by M. Kennedy and H. Radjavi for bounded operators on a Banach space to the more general situation of Banach algebras. The main ingredients are Vesentini’s result on subharmonicity of

Subharmonic functions in sub-Riemannian settings [PDF]
In this paper we furnish mean value characterizations for subharmonic functions related to linear second order partial differential operators with nonnegative characteristic form, possessing a well-behaved fundamental solution 0.

Hessian measures in the class of m-convex (m - cv) functions
The theory of m-convex (m − cv) functions is a new direction in the real geometry. In this work, by using the connection m − cv functions with strongly m-subharmonic (shm) functions and using well-known and rich properties of shm functions, we show a ...
