Concavity properties for free boundary elliptic problems
, 2010 We prove some concavity properties connected to nonlinear Bernoulli type free boundary problems. In particular, we prove a Brunn-Minkowski inequality and an Urysohn's type inequality for the Bernoulli Constant and we study the behaviour of the free ...

Bernoulli free-boundary problems in strip-like domains and a property of permanent waves on water of finite depth [PDF]
, 2007 We study weak solutions for a class of free-boundary problems which includes as a special case the classical problem of travelling gravity waves on water of finite depth.

On a mathematical model of tumor growth based on cancer stem cells
Mathematical Biosciences and Engineering, 2012 We consider a simple mathematical model of tumor growth based on cancer stem cells. The model consists of four hyperbolic equations of first order to describe the evolution ofdifferent subpopulations of cells: cancer stem cells, progenitor cells ...

A Class of Free Boundary Problems with Onset of a new Phase
, 2006 A class of diffusion driven Free Boundary Problems is considered which is characterized by the initial onset of a phase and by an explicit kinematic condition for the evolution of the free boundary.

Optimal Investment with Stopping in Finite Horizon [PDF]
, 2014 In this paper, we investigate dynamic optimization problems featuring both stochastic control and optimal stopping in a finite time horizon. The paper aims to develop new methodologies, which are significantly different from those of mixed dynamic ...

One dimensional parabolic free boundary problems [PDF]
, 1975 The method of lines is used to approximate explicit and implicit free boundary problems for a linear one dimensional diffusion equation with a sequence of free boundary problems for ordinary differential equations.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Flows in porous media with erosion of the solid matrix
Networks and Heterogeneous Media, 2010 We consider the flow of an incompressible Newtonian fluid through anidealized porous medium consisting of an array of identical solid symmetriclamellae, whose profile varies in space and time due to a stress inducederosion process.

Free boundary problems in controlled release pharmaceuticals. I: diffusion in glassy polymers [PDF]
, 1988 This paper formulates and studies two different problems occurring in the formation and use of pharmaceuticals via controlled release methods. These problems involve a glassy polymer and a penetrant, and the central problem is to predict and control the ...
