A priori estimates for quasilinear degenarate parabolic equations
Full text linkWe prove some maximum and gradient estimates for classical solutions to a wide class of quasilinear degenerate parabolic equations, including first order ones. The proof is elementary and exploits the smallness of the domain in the time direction
The Spanish flu and the health system: Considerations from the city of Parma, 1918
Full text linkBACKGROUND
The gravity of the Spanish flu has been often associated with inadequate health systems.
However, few studies have used health data effectively in their analysis of epidemics.
OBJECTIVE
To analyze the role of hospitals in an Italian town during the Spanish flu and its effect on
the risk of dying at home.
METHODS
Individual-level information from the Permission of Burials was used to evaluate the
impact of the epidemic on city hospitals. A logistic model was used to estimate the odds
of a home death in order to elucidate possible sociodemographic mechanisms linked to
hospital saturation issues.
RESULTS
During the epidemic the odds of dying at home increased by 29% overall, driven
especially by an increase in home deaths among the poorest social groups. However, the
well-off maintained the highest odds of dying at home throughout 1918.
CONCLUSIONS
Hospitals facilitated the spread of the epidemic in the city and contributed to its high
mortality level. The increase in the odds of dying at home for the poorest was likely
associated with hospital saturation, which conversely does not appear to have affected
the well-off. In fact, this social group already had very high levels of home deaths in the
pre-epidemic period.
CONTRIBUTION
Evaluating the role of hospitals during the Spanish flu allows better comprehension of
the spread and evolution of the epidemic, especially regarding possible saturation issues
and differential access to health resource
Long time behavior of Riemannian mean curvature flow of graphs
Full text linkAbstractIn this paper we consider long time behavior of a mean curvature flow of nonparametric surface in Rn, with respect to a conformal Riemannian metric. We impose zero boundary value, and we prove that the solution tends to 0 exponentially fast as t→∞. Its normalization u/supu tends to the first eigenfunction of the associated linearized problem
