In-medium nuclear interactions of low-energy hadrons
Experimental and theoretical developments of the last decade in the study of
exotic atoms and some related low-energy reactions are reviewed, in order to
provide information on the in-medium hadron-nucleon t matrix over a wide range
of densities up to central nuclear densities. In particular, we review pionic
deeply bound atomic states and related evidence for partial restoration of
chiral symmetry in dense nuclear matter. The case for relatively narrow deeply
bound atomic states for antikaons and antiprotons is made, based on the physics
of strong nuclear absorption. Recent experimental suggestions for signals of
antikaon-nuclear deeply bound states are reviewed, and dynamical models for
calculating binding energies, widths and densities of antikaon nuclear states
are discussed. Specific features of low-energy in-medium interactions of kaons,
antiprotons and of Sigma hyperons are discussed, and suggestions to study
experimentally Cascade atoms are reviewed.Comment: 86 pages, 44 figures, slight revisions, references added, Physics

Necrotic tumor growth: an analytic approach
The present paper deals with a free boundary problem modeling the growth
process of necrotic multi-layer tumors. We prove the existence of flat
stationary solutions and determine the linearization of our model at such an
equilibrium. Finally, we compute the solutions of the stationary linearized
problem and comment on bifurcation.Comment: 14 pages, 3 figure
The Distributional Impacts of Indonesia's Financial Crisis on Household Welfare: "A Rapid Response Methodology"
Analyzing the distributional impacts of economic crises is important and, unfortunately, an ever more pressing need. If policymakers are to intervene to help those most adversely impacted, then policymakers need to identify those who have been most harmed and the magnitude of that harm. Furthermore, policy responses to economic crises typically must be timely. In this paper, we develop a simple methodology to fill the order and we've applied our methodology to analyze the impact of the Indonesian economic crisis on household welfare there. Using only pre-crisis household information, we estimate the compensating variation for Indonesian households following the 1997 Asian currency crisis and then explore the results with flexible non-parametric methods. We find that virtually every household was severely impacted, although it was the urban poor that fared the worst. The ability of poor rural households to produce food mitigated the worst consequences of the high inflation. The distributional conseqences are the same whether we allow households to substitute towards relatively cheaper goods or not. However the geographic location of the household mattered even within urban or rural areas and household income categories. Additionally, households with young children may have suffered disproportionately adverse effects.http://deepblue.lib.umich.edu/bitstream/2027.42/39771/3/wp387.pd
