Limits of deconstruction, deconstructing limits

Limits in modified categories of interest

‎We firstly prove the completeness of the category of crossed modules in a modified category of interest‎. ‎Afterwards‎, ‎we define pullback crossed modules and pullback cat objects that are both obtained by pullback diagrams with extra structures on certain arrows‎. ‎These constructions unify many corresponding results for the cases of groups‎, ‎commutative algebras and can also be adapted to ...

Deconstructing Dimensional Deconstruction

Dimensional deconstruction (DD) abstracts from higher dimensional models features of related 4–dimensional ones. DD was proposed in Refs. [1–3] as a scheme for constructing models of naturally light composite Higgs boson. These are models in which—without fine–tuning of parameters—the composite Higgs’s mass M and vacuum expectation value v are much lighter than its binding energy scale Λ. We re...

Evaluation of the Results of Arthroscopic Release in Limits of Movement in Knees

Introduction: Limits of movement in knees is one of the most common complications following trauma and surgery. With early diagnosis and appropriate treatment choices, knee replacement and performance improvement are expected in many patients. However, limits of movement in knees is unpleasant and should be corrected as soon as possible. In this study, we decided to evaluate the results of arth...

Limits to science or limits to epistemology?

SFI WORKING PAPER: 1996-08-061 SFI Working Papers contain accounts of scientific work of the author(s) and do not necessarily represent the views of the Santa Fe Institute. We accept papers intended for publication in peer-reviewed journals or proceedings volumes, but not papers that have already appeared in print. Except for papers by our external faculty, papers must be based on work done at ...
