Let G be a finite group. For a prime p and a p-block B of G, we denote by Irr(B) the set of complex irreducible characters of G that belong to B. It was conjectured by Navarro and Willems [NW] that if for blocks Bp and Bq of G at different primes p, q we have an equality Irr(Bp) = Irr(Bq) then |Irr(Bp)| = 1. But then the first author of the present article found that the extension group 6.A7 of...

Background: Age estimation is of great importance in many medical fields and dentistry. It also extensively used archeology, criminology, forensic medicine. Considering the dental age estimation, this study was designed. Objectives: This aimed to evaluate accuracy Demirjian Willems methods for estimating 7 - 15-year-olds population north Iran. We modified method compared results original method...

Background: Age may be estimated using tooth eruption sequence and/or calcification stage. Because many factors affect the time of eruption, stage shows higher accuracy than eruption. Demirjian’s and Willems’ methods have been most commonly used for dental age estimation. Both Willems Demirjian use as an indicator. Studies comparing these shown varied results, they performed on different popula...

It is well known that a convolutional code is essentially a linear system defined over a finite field. In this paper we elaborate on this connection. We define a convolutional code as the dual of a complete linear behavior in the sense of Willems (1979). Using ideas from systems theory, we describe a set of generalized first-order descriptions for convolutional codes. As an application of these...

The problem of characterizing those linear systems that exhibit a symmetric behavior was completely solved in the 1D case, ten years ago, in a few papers by F. Fagnani and J. C. Willems. Unfortunately, that theory could not be extended in its full generality to multidimensional systems: the techniques used in the proofs limited the results to systems of independent equations and to a restricted...
