The doctrine of clinical equipoise is appealing because it appears to permit physicians to maintain their therapeutic obligation to offer optimal medical care to patients while conducting randomized controlled trials (RCTs). The appearance, however, is deceptive. In this article we argue that clinical equipoise is defective and incoherent in multiple ways. First, it conflates the sound methodol...

We study the transition from coherent to incoherent dynamics in a nonlinear triplet of broadband combs of waves. Expanding the analysis of previous works, we investigate what happens when the band of available modes is much larger than that of the initial narrower combs within which the nonlinear interaction is not subjected to selection rules involving wave momenta. Here selection rules are pr...

We develop a new primal-dual witness proof framework that may be used to establish variable selection consistency and ∞-bounds for sparse regression problems, even when the loss function and regularizer are nonconvex. We use this method to prove two theorems concerning support recovery and ∞-guarantees for a regression estimator in a general setting. Notably, our theory applies to all potential...

This letter considers the problem of dictionary learning for sparse signal representation whose atoms have low mutual coherence. To learn such dictionaries, at each step, we first update the dictionary using the method of optimal directions (MOD) and then apply a dictionary rank shrinkage step to decrease its mutual coherence. In the rank shrinkage step, we first compute a rank 1 decomposition ...

Ontology matching has become an important field of research over the last years. Although many different approaches have been proposed, only few of them are committed to a well defined semantics. As a consequence, the possibilities of reasoning are not exploited to their full extent. A reasoning based approach will not only improve ontology matching, but will also be necessary to solve certain ...

FOR "THE IRRELEVANCE/INCOHERENCE OF NON-REDUCTIONISM ABOUT PERSONAL IDENTITY" Before being able to answer key practical questions dependent on a criterion of personal identity (e.g., am I justified in anticipating surviving the death of my body?), we must first determine which general approach to the issue of personal identity is more plausible, reductionism or non-reductionism. While reduction...

In many signal processing applications, one wishes to acquire images that are sparse in transform domains such as spatial finite differences or wavelets using frequency domain samples. For such applications, overwhelming empirical evidence suggests that superior image reconstruction can be obtained through variable density sampling strategies that concentrate on lower frequencies. The wavelet a...
