A characterization of the degenerate complex Hessian equations for functions with bounded (p,m)-energy

ANNALI SCUOLA NORMALE SUPERIORE - CLASSE DI SCIENZE, 2023
By proving an estimate of the sublevel sets for $( ,m)$-subharmonic functions we obtain a Sobolev type inequality that is then used to characterize the degenerate complex Hessian equations for such functions with bounded $(p,m)$-energy.

Generalized gradient expansions in quantum transport equations [PDF]

, 1996
Gradient expansions in quantum transport equations of a Kadanoff-Baym form have been reexamined. We have realized that in a consistent approach the expansion should be performed also inside of the self-energy in the scattering integrals of these ...

Boundary Ground Ring in 2D String Theory

, 2003
The 2D quantum gravity on a disc, or the non-critical theory of open strings, is known to exhibit an integrable structure, the boundary ground ring, which determines completely the boundary correlation functions.

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

A Novel Approach for Simulation of Automotive Radar Sensors Designed for Systematic Support of Vehicle Development

Sensors, 2023
Despite the progress in driving automation, the market introduction of higher-level automation has not yet been achieved. One of the main reasons for this is the effort in safety validation to prove functional safety to the customer.

On the period function for a family of complex differential equations

Journal of Differential Equations, 2006
Planar differential equations of the form \(\dot{z}=f(z)g(\overline{z})\), where \(f(z)\) and \(g(z)\) holomorphic functions, are considered, and it is proven that if \(g(z)\) is not constant then for any continuum of period orbits, the period function has at most one isolated critical period, which is a minimum.
