Reversing concepts on COPD irreversibility.

" C ommon diseases are complex. The study of complexity is based on a new way of thinking that stands in sharp contrast to the philosophy underlying Newtonian science, which is based on reductionism, determinism and objective knowledge. Initially, we might aim to reduce complexity to understand nature [1]. In the current issue of the European Respiratory Journal (ERJ), TASHKIN et al. [2] report...

On Reversing Jensen's Inequality

Alex Pentland MIT Media Lab Cambridge, MA 02139 [email protected] Jensen's inequality is a powerful mathematical tool and one of the workhorses in statistical learning. Its applications therein include the EM algorithm, Bayesian estimation and Bayesian inference. Jensen computes simple lower bounds on otherwise intractable quantities such as products of sums and latent log-likelihoods. This s...

On completeness of word reversing

Word reversing is a combinatorial operation on words that detects pairs of equivalent words in monoids that admit a presentation of a certain form. Here we give conditions for this method to be complete in the sense that every pair of equivalent words can be detected by word reversing. In addition, we obtain explicit upper bounds on the complexity of the process. As an application, we show that...

Reversing opinions on Dollo's Law.

Dollo's Law, the idea that the loss of complex features in evolution is irreversible, is a popular concept in evolutionary biology. Here we review how application of recent phylogenetic methods, genomics and evo-devo approaches is changing our view of Dollo's Law and its underlying mechanisms. Phylogenetic studies have recently demonstrated cases where seemingly complex features such as digits ...

Analogue experiments on irreversibility of classical fluctuations

LARGE FLUCTUATIONS occur universally in Nature. They are responsible for e.g. nucleation at phase transitions, chemical reactions, mutations in DNA sequences, protein transport in biological cells, and failures of electronic devices. The idea that they provide a conceptual bridge between microscopic and macroscopic motion underlies many discussions2−5 of how the irreversible thermodynamic behav...
