background: we conducted a retrospective analysis to evaluate the impact of omission of supraclavicular radiotherapy on supraclavicular failure rate and treatment outcomes in n1 breast cancer patients with evaluation of prognostic factors that affected supraclavicular recurrence free survival. methods: this study analyzed the medical records of 109 patients with n1 breast cancer. all patients u...

This paper demonstrates that genetic programming can be used to automatically create the design for both the topology and parameter values (tuning) for a common parameterized controller for all the plants in two families of plants that are representative of typical industrial processes. The genetically evolved controller is "general" in the sense that it contains free variables representing the...

We make a formal sociologic study of the concept of free will. By using the language of mathematics and logic, we define what we call everlasting societies. Everlasting societies never age: persons never age, and the goods of the society are indestructible. The infinite history of an everlasting society unfolds by following deterministic and probabilistic laws that do their best to satisfy the ...

In ordinary rst order logic, a valid inference in a language L is one in which the conclusion is true in every model of the language in which the premises are true. To accommodate inductive/uncertain/probabilistic/nonmonotonic inference, we weaken that demand to the demand that the conclusion be true in a large proportion of the models in which the relevant premises are true. More generally, we...

The equivalence between autonomicity and the absence of free variables is a well-known result for linear, shift-invariant and complete behaviors over a field. However, this no longer holds for a behavior that does not satisfy one of those properties. In this paper we consider linear, shift-invariant and complete behaviors over the ring Zpr and study under which conditions such behaviors are aut...
