Coarse-graining as a Route to Microscopic Physics: the Renormalization Group in Quantum Field Theory
The renormalization group (RG) has been characterized as merely a coarse-graining procedure that does not illuminate the microscopic content of quantum field theory (QFT), but merely gets us from that content, as given by axiomatic QFT, to macroscopic predictions. I argue that in the constructive field theory tradition, RG techniques do illuminate the microscopic dynamics of a QFT, which are no...
Performance of interferon-γ (IFN-γ) release assays still needs to be improved. The data on the performance of QuantiFERON-TB Gold Plus (QFT-Plus), a new-generation of QFT assay are limited. This study evaluated the diagnostic performance of QFT-Plus, and compared to that of QuantiFERON-TB Gold In-Tube (QFT-GIT). Blood samples were collected from 162 bacteriologically confirmed tuberculosis (TB)...
The hypothesis that T-cell interferon-gamma responses to Mycobacterium tuberculosis-specific antigens decline as disease activity diminishes with tuberculosis (TB) treatment has generated interest in the interferon-gamma release assays (IGRAs) as treatment-monitoring tools. We studied the effect of TB treatment on these responses as measured by the QuantiFERON-TB Gold In-tube (QFT-IT) and T-SPO...
We present an introduction to phase-space techniques ~PST! based on a quantum-field-theoretical ~QFT! approach. In addition to bridging the gap between PST and QFT, our approach results in a number of generalizations of the PST. First, for problems where the usual PST do not result in a genuine Fokker-Planck equation ~even after phase-space doubling! and hence fail to produce a stochastic diffe...

One of the classical problems of nonlinear systems and control theory is feedback linearization. Its obvious motivation is that one can utilize linear control theory if the nonlinear system at hand is linearizable by feedback. This problem is well-understood for the smooth nonlinear systems. In the present paper, we investigate feedback linearizability of a class of piecewise linear, and hence ...
This is a preliminary account of coincidences between algebraic QFT and some recent observations on \light cone quantization" and applications to \M" theory. The most surprising correspondence is that between the existence of wedge aaliated semiglobal eld coordinates without vacuum polarization and those light cone elds (on which \Matrix" theory is based) with analogous properties. There is als...
