For Most Large Underdetermined Systems of Linear Equations the Minimal ℓ1norm Solution is also the Sparsest Solution
 Comm. Pure Appl. Math
, 2004
"... We consider linear equations y = Φα where y is a given vector in R n, Φ is a given n by m matrix with n < m ≤ An, and we wish to solve for α ∈ R m. We suppose that the columns of Φ are normalized to unit ℓ 2 norm 1 and we place uniform measure on such Φ. We prove the existence of ρ = ρ(A) so that ..."

that for large n, and for all Φ’s except a negligible fraction, the following property holds: For every y having a representation y = Φα0 by a coefficient vector α0 ∈ R m with fewer than ρ · n nonzeros, the solution α1 of the ℓ 1 minimization problem min �x�1 subject to Φα = y is unique and equal to α0
ORIGINAL INVESTIGATION Equal proportions of affected cells in muscle and blood of a mosaic carrier of facioscapulohumeral muscular dystrophy
"... Abstract Autosomal dominant facioscapulohumeral muscular dystrophy (FSHD) is associated with contractions of D4Z4 repeat on 4q35. It displays a remarkable interand intrafamilial clinical variability ranging from severe phenotype to asymptomatic carriers. Mosaicism for the contracted FSHDsized al ..."

D4Z4 repeat on 4q35 in the mother and mosaicism for an expanded D4Z4 repeat on 10q26 in the affected daughter. The results show that the proportion of mosaicism in PBL and muscle were comparable, while in fibroblasts there was some variation in the mosaicism, which might be caused by culturing
The ventriloquist effect results from nearoptimal bimodal integration
 Curr. Biol
, 2004
"... Results for the various unimodal location discriminations for naive observer L.M. are shown in Figure 1A. The curves plot the proportion of trials in which the second stimulus was seen to the left of the first, as a function of actual physical displacement. Following standard practice, the data were ..."

Developments in the Measurement of Subjective WellBeing
 Psychological Science.
, 1993
"... F or good reasons, economists have had a longstanding preference for studying peoples' revealed preferences; that is, looking at individuals' actual choices and decisions rather than their stated intentions or subjective reports of likes and dislikes. Yet people often make choices that b ..."

are a more accurate gauge of actual feelings if they are reported closer to the time of, and in direct reference to, the actual experience. We conclude by proposing the Uindex, a misery index of sorts, which measures the proportion of time that people spend in an unpleasant state, and has the virtue
Equal Protection Implies Proportional Representation
, 2004
"... This paper shows that for a singlevote electoral system for a representative body to treat all voters and all parties equally, it must produce results essentially identical to list proportional representation (PR). Democratic theory has often been agnostic concerning representative institutions. Di ..."

Bayesian inference on phylogeny and its impact on evolutionary biology.
 Science
, 2001
"... 1 As a discipline, phylogenetics is becoming transformed by a flood of molecular data. These data allow broad questions to be asked about the history of life, but also present difficult statistical and computational problems. Bayesian inference of phylogeny brings a new perspective to a number of o ..."

). Usually all trees are considered a priori equally probable, and the likelihood is calculated under one of a number of standard Markov models of character evolution. The posterior probability, although easy to formulate, involves a summation over all trees and, for each tree, integration over all possible
Adaptive resource allocation in multiuser OFDM systems with proportional rate constraints
 IEEE Trans. Wireless Commun
, 2005
"... Abstract—Multiuser orthogonal frequency division multiplexing (MUOFDM) is a promising technique for achieving high downlink capacities in future cellular and wireless local area network (LAN) systems. The sum capacity of MUOFDM is maximized when each subchannel is assigned to the user with the b ..."

algorithm, subchannel allocation is first performed by assuming an equal power distribution. An optimal power allocation algorithm then maximizes the sum capacity while maintaining proportional fairness. The proposed algorithm is shown to achieve about 95 % of the optimal capacity in a twouser system
Private equity performance: Returns, persistence and capital flows
, 2003
"... This paper investigates the performance and capital inflows of private equity partnerships. Average fund returns (net of fees) approximately equal the S&P 500 although there is substantial heterogeneity across funds. Returns persist strongly across different funds raised by a partnership. Better ..."

PACER: Proportional Detection of Data Races ∗
"... Data races indicate serious concurrency bugs such as order, atomicity, and sequential consistency violations. Races are difficult to find and fix, often manifesting only in deployment. The frequency of these bugs will likely increase as software adds parallelism to exploit multicore hardware. Unfort ..."

. Unfortunately, sound and precise race detectors slow programs by factors of eight or more, which is too expensive to deploy. This paper presents a precise, lowoverhead samplingbased data race detector called PACER. PACER makes a proportionality guarantee: it detects any race at a rate equal to the sampling
