On the importance of pivot language selection for statistical machine translation
 In Proceedings of Human Language Technologies: The Annual Conference of the North American Chapter of the Association for Computational Linguistics, NAACLHLT ’09
, 2009
"... Recent research on multilingual statistical machine translation focuses on the usage of pivot languages in order to overcome resource limitations for certain language pairs. Due to the richness of available language resources, English is in general the pivot language of choice. In this paper, we inv ..."

Psychology and neurobiology of simple decisions
 Trends Neurosci
, 2004
"... Patterns of neural firing linked to eye movement decisions show that behavioral decisions are predicted by the differential firing rates of cells coding selected and nonselected stimulus alternatives. These results can be interpreted using models developed in mathematical psychology to model behavi ..."

provide a quantitative link between the timecourse of behavioral decisions and the growth of stimulus information in neural firing data. The question of how twoalternative decisions are made is an important one for neuroscience and psychology alike because of the pivotal role played by decision making
Pivoting for Structured Matrices with Applications
, 1997
"... Gaussian elimination is a standard tool for computing triangular factorizations for general matrices, and thereby solving associated linear systems of equations. As is wellknown, when this classical method is implemented in niteprecisionarithmetic, it often fails to compute the solution accura ..."

This problem motivated a number of interesting and important studies in modern numerical linear algebra; for our purposes in this paper we only mention that starting with the breakthrough work
Direct pivotal predictive inference ∗
, 2004
"... Without assuming any pdf for some measured parameter, we derive a predictive pdf for the outcome of a second measurement, given the outcome of the first measurement and two common assumptions about the noise. These are that (1) it is additive, and (2) it is of some known pdf. The argument is based o ..."

Testing Proposer Pivot Models*
, 2003
"... We experimentally test competing theories of threeplayer majoritarian bargaining models with fixed, known reservation values. Subjects are randomly assigned to three roles: a proposer and two types of voters. Each role is randomly assigned a reservation value, i.e. a given amount of money he/she wi ..."

allows us to obtain different implications from each hypothesis. We find that each hypothesis is inconsistent with our data in important respects. In particular, subjects strongly respond to changes in reservation values as if In 1978 Romer and Rosenthal published an alternative to Black’s median voter
A New Pivoting Strategy For Gaussian Elimination
, 1996
"... . This paper discusses a method for determining a good pivoting sequence for Gaussian elimination, based on an algorithm for solving assignment problems. The worst case complexity is O(n 3 ), while in practice O(n 2:25 ) operations are sufficient. 1991 MSC Classification: 65F05 (secondary 90B80 ..."

HIV1 genome nuclear import is mediated by a central DNA flap. Cell 101:173–185
, 2000
"... differentiated primary macrophages (Gartner et al., 1986). HIV DNA integrates in the chromatin of nonmitotic target cells (Weinberg et al., 1991), implying that HIV1 PICs are able to cross the nuclear membrane of host cells (Bukrinsky et al., 1992). Thus, mitosisindependent nuclear import is a piv ..."

A Dynamic Pivot Selection Technique for Similarity Search ∗
"... All pivotbased algorithms for similarity search use a set of reference points called pivots. The pivotbased search algorithm precomputes some distances to these reference points, which are used to discard objects during a search without comparing them directly with the query. Though most of the al ..."

of the algorithms proposed to date select these reference points at random, previous works have shown the importance of intelligently selecting these points for the index performance. However, the proposed pivot selection techniques need to know beforehand the complete database to obtain good results, which
A Survey on Pivot Rules for Linear Programming
 ANNALS OF OPERATIONS RESEARCH. (SUBMITTED
, 1991

The purpose of this paper is to survey the various pivot rules of the simplex method or its variants that have been developed in the last two decades, starting from the appearance of the minimal index rule of Bland. We are mainly concerned with the finiteness property of simplex type pivot rules. Th ..."
