Very Low Pressure Pyrolysis of Phenylacetic Acid

Recent reviews on the thermochemistry of organic radicals in the gas phase,'*2 have pointed out the necessity of a reassessment of the heat of formation of the hydroxycarbonyl radical and the corresponding bond-dissociation energy Ed in formic acid. Based on a re-evaluation of the early work of Back and S e h ~ n , ~ McMillen and Golden,' have recommended A,H('CO,H) = -209.2 kJ mol-'; however, ...

Beyond Low Rank + Sparse: A Multi-scale Low Rank Decomposition

We present a multi-scale version of low rank matrix decomposition. Our motivation comes from imaging applications, in which image sequences are correlated locally on several scales in space and time rather than globally. We model our data matrix as a sum of matrices, where each matrix has increasing scales of locally low-rank matrices. Using this multi-scale modeling, we can capture different s...

Rank Determination for Low-Rank Data Completion

Recently, fundamental conditions on the sampling patterns have been obtained for finite completability of low-rank matrices or tensors given the corresponding ranks. In this paper, we consider the scenario where the rank is not given and we aim to approximate the unknown rank based on the location of sampled entries and some given completion. We consider a number of data models, including singl...
