True or false GPS-derived deformations?
Deformation analysis GPS networks igm 95 rome area
2015/9/28
In this paper we focus on the question whether GPS networks born with cartographic aims can be safely used in crustal deformation control. We carried out a test on a network of five vertices located i...
Adapting to Unknown Sparsity by controlling the False Discovery Rate
Thresholding Wavelet Denoising Minimax Estimation
2015/8/21
We attempt to recover a high-dimensional vector observed in white noise, where
the vector is known to be sparse, but the degree of sparsity is unknown. We consider
three di®erent ways of deˉnin...
Asymptotic Minimaxity of False Discovery Rate Thresholding for Sparse Exponential Data
Minimax Decision theory Minimax Bayes estimation
2015/8/21
Control of the False Discovery Rate (FDR) is a recent innovation in multiple hypothesis
testing, allowing the user to limit the fraction of rejected null hypotheses which correspond to
false rejecti...
Modern scientific technology is providing a new class of large-scale simultaneous
inference problems, with hundreds or thousands of hypothesis tests to consider at the
same time. Microarrays e...
False Discovery Rates and Copy Number Variation
False discovery rate multiple testing grouped hypotheses
2015/8/20
Copy number changes, the gains and losses of chromosome segments, are a common type
of genetic variation among healthy individuals as well as an important feature in tumor
genomes. Microarray techno...
Modern scientific technology has provided a new class of large-scale simultaneous inference
problems, with thousands of hypothesis tests to consider at the same time. Microarrays epitomize this...
Controversial Clues of Two 'Goldilocks Planets' That Might Support Life are Proven False
Dwarfs Liquid water Stars Rock The planets Radiation Astrophysics
2014/7/18
03 July 2014 — Mysteries about controversial signals coming from a dwarf star considered to be a prime target in the search for extraterrestrial life now have been solved in research led by scientists...
Towards a theoretical understanding of false positives in DNA motif finding
theoretical understanding false positives DNA motif finding
2011/1/5
Detection of false-positive motifs is one of the main causes of low performance in motif finding methods. It is generally assumed that false-positives are mostly due to algorithmic weakness of motif-f...
Control of the False Discovery Rate Under Arbitrary Covariance Dependence
Rate Covariance Dependence
2011/1/4
Multiple hypothesis testing is a fundamental problem in high dimensional inference, with wide applications in many scientific fields. In genome-wide association studies, tens of thousands of tests are...
Constrained potential method for false vacuum decays
Constrained potential method false vacuum decays
2010/12/27
A procedure is reported for numerical analysis of false vacuum transition in a model with multiple scalar fields. It is a refined version of the approach by Konstandin and Huber. The alteration makes...
Is the five-flow conjecture almost false?
Nowhere–zero flows flow polynomial flow roots Tutte’s five–flow conjecture
2010/12/9
The number of nowhere-zero ZQ flows on a graph G can be shown to be a polynomial in Q,efining the flow polynomial G(Q). According to Tutte’s five-flow conjecture,G(5) > 0 for any bridgeless G.
We consider a lognormal diffusion market and prove that the average portfolio does not provide accurate dynamics of the real portfolio, and the expected functionals of the average portfolio do not app...
