Contrary to conventional economic growth theory, which reduces a country's output one aggregate variable (GDP), product diversity is central development, as recent “economic complexity” research suggests. A reflects its of knowhow or “capabilities”. Researchers proposed the Economic Complexity Index (ECI) and country Fitness index estimate number capabilities from international export data; the...

Internet supercomputing is an approach to solving partitionable, computation-intensive problems by harnessing the power of a vast number of interconnected computers. For the problem of using network supercomputing to perform a large collection of independent tasks, prior work introduced a decentralized approach and provided randomized synchronous algorithms that perform all tasks correctly with...

in synthetic aperture radar (sar) imagery, ship-sea contrast can be significantly improved when the polarimetric information is used, compared with information from a single channel sar. the constant false alarm rate (cfar) detection algorithm based on the alpha-stable (as) distribution model is a descent method for ship detection in sea. the most important step in this method is the parameter ...

We describe a method for computing provably exact maximum a posteriori (MAP) estimates for a subclass of problems on graphs with cycles. The basic idea is to represent the original problem on the graph with cycles as a convex combination of tree-structured problems. A convexity argument then guarantees that the optimal value of the original problem (i.e., the log probability of the MAP assignme...

Dark matter detection rates for supergravity models with R parity where supersymmetry is broken at a scale > ∼ MG are discussed. Non-universal soft breaking masses in both the Higgs and squark sectors are considered, and it is seen that these can effect rates by a factor of 10 100 when mχ̃0 1 < ∼ 65 GeV (χ01 = lightest neutralino) but otherwise make relatively small corrections. The b → s+γ bran...

Cultures of mutant cni-1, a chromosomal mutant of Neurospora crassa, undergo a marked change in respiratory properties as the age of the culture increases. Early log phase cultures have a high level of respiration that is insensitive to inhibition by cyanide or antimycin A. Late log and stationary phase cultures have reduced rates of respiration. A high percentage of this respiration is inhibit...

Do political connections increase bank risk-taking, or do they work as a financial safety net ex post? Using a data set of lobbying activities by US financial institutions, this paper provides empirical evidence that lobbying activities reduce banks’ risks under the presence of government bailouts. First, I uncover from an event study the fact that political connections and government bailouts ...

High-level speaker-specific features (HLSSFs), such as the style of pronunciation of words, their use, phonotactics and prosody, form the main subjects of state-of-the-art research on automatic speaker recognition (ASR). In this paper, we experimentally verify HLSSF extraction and support vector machine (SVM)-based modelling techniques. The HLSSF extraction produces patterns of symbols for each...
