Loopy belief propagation for approximate inference: An empirical study. In:
 Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" the use of Pearl's polytree algorithm in a Bayesian network with loops can perform well in the context of errorcorrecting codes. The most dramatic instance of this is the near Shannonlimit performanc ..."

in a more gen eral setting? We compare the marginals com puted using loopy propagation to the exact ones in four Bayesian network architectures, including two realworld networks: ALARM and QMR. We find that the loopy beliefs of ten converge and when they do, they give a good approximation

"... This study of 89 Flemish highschool students' grades for L1 (Dutch), L2 (French), L3 (English) and L4 (German) investigates the effects of three higherlevel personality dimensions (psychoticism, extraversion, neuroticism), one lowerlevel personality dimension (foreign language anxiety) and ..."

. Gender and social class had no effect. Strong positive correlations between grades in the different languages could point to an underlying sociocognitive dimension. The implications of these findings are discussed. doi: 10.2167/ijm080.0 Keywords: extraversion, neuroticism, psychoticism, foreign language
Globalization and the Gains from Variety
 Quarterly Journal of Economics
, 2006
"... Since the seminal work of Krugman, product variety has played a central role in models of trade and growth. In spite of the general use of loveofvariety models, there has been no systematic study of how the import of new varieties has contributed to national welfare gains in the United States. In ..."

this time period was 28 percent or 1.2 percentage points per year. We estimate the value to U. S. consumers of the expanded import varieties between 1972 and 2001 to be 2.6 percent of GDP. I.
Consciousness reconsidered
, 1992
"... of mind, evolution of consciousness 1.1 Owen Flanagan is very clear about what his latest book, Consciousness Reconsidered is supposed to do. He writes that ``we can make intelligible the existence of consciousness in the natural world,' ' (p. 2) and that his ``aim is to say something illu ..."

terms' ' (p. 1). 1.2 We remark upon this because what Flanagan actually accomplishes in the book is almost exactly the opposite of his expectations. That is, he in fact provides several very persuasive arguments against nonnaturalism, yet (in our opinion) is not successful at explaining
Exact solutions for Loewner evolutions
 J. Stat. Phys
, 2004
"... In this note, we solve the Loewner equation in the upper halfplane with forcing function t(t), for the cases in which t(t) has a powerlaw dependence on time with powers 0, 1/2, and 1. In the first case the trace of singularities is a line perpendicular to the real axis. In the second case the trac ..."

the trace of singularities can do three things. If t(t)=2`ot, the trace is a straight line set at an angle to the real axis. If t(t)=2`o(1−t), as pointed out by Marshall and Rohde, (12) the behavior of the trace as t approaches 1 depends on the coefficient o. Our calculations give an explicit solution
On the Exact Worst Case Query Complexity of Planar Point Location
 IN PROCEEDINGS OF THE NINTH ANNUAL ACMSIAM SYMPOSIUM ON DISCRETE ALGORITHMS
, 1998
"... What is the smallest constant c so that the planar point location queries can be answered in c log 2 n + o(log n) steps (i.e. pointline comparisons) in the worst case? In SODA 97 Goodrich, Orletsky, and Ramaiyer [6] showed that c = 2 is possible using linear space and conjectured this to be optimal ..."

this to be optimal. We disprove this conjecture and show that c = 1 can be achieved. Moreoever by giving upper and lower bounds we show that without space restrictions the worst case query complexity of planar point location differs from log 2 n + 2 p log 2 n at most by an additive factor of (1=2)log 2 log 2 n +O
Continuity and discontinuity of behavioral inhibition and exuberance: Psychophysiological and behavioral influences across the first four years of life.
 Child Development,
, 2001
"... Abstract: Fourmonthold infants were screened (N = 433) for temperamental patterns thought to predict behavioral inhibition, including motor reactivity and the expression of negative affect. Those selected (N = 153) were assessed at multiple age points across the first 4 years of life for behavior ..."

If it did exist, it would provide an exact bicovering, in 21 blocks of size 5, of the pairs from 15 points. However, we show that 22 quintuples are sufficient to provide a bicover of the pairs from 15 points; thu ..."

We show that for ∆ = 1/2 the integrals can be separated and computed exactly. As an example we give the explicit results up to the lattice dist ..."
