Increasing Returns and Economic Geography

by Paul Krugman - Journal of Political Economy , 1991
"... This paper develops a simple model that shows how a country can endogenously become differentiated into an industrialized "core" and an agricultural "periphery. " In order to realize scale economies while minimizing transport costs, manufacturing firms tend to locate in the regio ..."

in the region with larger demand, but the location of demand itself depends on the distribution of manufacturing. Emergence of a core-periphery pattern depends on transportation costs, economies of scale, and the share of manufacturing in national income. The study of economic geography-of the location

The Determinants of Credit Spread Changes.

"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

include several liquidity, macroeconomic, and financial variables as candidate proxies for this factor. We cannot, however, find any set of variables that can explain the bulk of this common systematic factor. Our findings suggest that the dominant component of monthly credit spread changes

A Variational Level Set Approach to Multiphase Motion

by Hong-kai Zhao, T. Chan, B. Merriman, S. Osher - JOURNAL OF COMPUTATIONAL PHYSICS 127, 179–195 (1996) ARTICLE NO. 0167 , 1996
"... A coupled level set method for the motion of multiple junctions (of, e.g., solid, liquid, and grain boundaries), which follows the gradient flow for an energy functional consisting of surface tension (proportional to length) and bulk energies (proportional to area), is sin �1 developed. The approach ..."

Renormalization group flows from holography -- Supersymmetry and a c-theorem

by D. Z. Freedman, S. S. Gubser, K. Pilch, N. P. Warner - ADV THEOR. MATH. PHYS , 1999
"... We obtain first order equations that determine a supersymmetric kink solution in fivedimensional N = 8 gauged supergravity. The kink interpolates between an exterior anti-de Sitter region with maximal supersymmetry and an interior anti-de Sitter region with one quarter of the maximal supersymmetry. ..."

between fields of bulk supergravity in the interior anti-de Sitter region and composite operators of the infrared field theory. We also point out that the truncation used to find the reduced symmetry critical point can be extended to obtain a new N = 4 gauged supergravity theory holographically dual to a

The dS/CFT correspondence

by Andrew Strominger - JHEP , 2001
"... A holographic duality is proposed relating quantum gravity on dSD (D-dimensional de Sitter space) to conformal field theory on a single SD−1 ((D-1)-sphere), in which bulk de Sitter correlators with points on the boundary are related to CFT correlators on the sphere, and points on I + (the future bou ..."

MICROSCOPIC AND BULK SPECTRA OF DIRAC OPERATORS FROM FINITE-VOLUME PARTITION FUNCTIONS

Coil sensitivity encoding for fast MRI. In:

by Klaas P Pruessmann , Markus Weiger , Markus B Scheidegger , Peter Boesiger - Proceedings of the ISMRM 6th Annual Meeting, , 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

shape criterion is weaker in favor of the SNR. With both strategies the reconstruction algorithm is numerically demanding in the general case. This is mainly because with hybrid encoding the bulk of the work of reconstruction can usually not be done by fast Fourier transform (FFT). However, it is shown

Stabilization of metallic supercooled liquid and bulk amorphous alloys

by Akihisa Inoue - Acta Mater , 2000
"... Abstract—Bulk metallic materials have ordinarily been produced by melting and solidification processes for the last several thousand years. However, metallic liquid is unstable at temperatures below the melting temperature and solidifies immediately into crystalline phases. Consequently, all bulk en ..."
