This paper is the second part of a work dealing with two Schiitzenberger's conjectures on variable-length codes. It contains the detailed proofs of the characterization that we obtained for the degree and the decomposability of finite maximal codes over the alphabet {a, b} with at most 3 occurrences of the letter b in each word.

Populations of young star clusters show significant differences even among “normal” disk galaxies. In this contribution I discuss how properties of young cluster systems are related to those of their host galaxies, based on a recent study of clusters in a sample of 22 nearby spiral galaxies. Luminous young clusters similar to the “super” star clusters observed in starbursts and mergers exist in...

Future practice profile Most (80.7%) respondents expected to practise as family physicians. Many different services are provided by family physicians across the country, as was shown by the 1997-1998 National Family Physician Survey conducted by the College of Family Physicians of Canada (CFPC). These services include obstetric and prenatal care, emergency care, inpatient care, child health, ca...

Documented Mississippi physician shortages' make evidence about factors shaping physicians' career choices especially important if Mississippi policymakers are to devise workable strategies to maximize the physician workforce. Work-life interactions influence physicians' choices about how they manage their careers and professional burnout is one documented cause of physicians' decisions to chan...

In the mid-to-large volume manufacturing operations, a Single Part Manufacturing System (SPMS) is usually used to produce one part model. As the progress of manufacturing technologies, modern manufacturing systems such as reconfigurable manufacturing systems (RMS), are more capable of producing a family of part models, such a system is often referred to as a Multiple Parts Manufacturing System ...

In order to overcome some unavoidable factors, like shift of the part, that influence the crisp neural networks’ recognition, the present study is dedicated in developing a novel fuzzy neural network (FNN), which integrates both the fuzzy set theory and adaptive resonance theory 2 (ART2) neural network for grouping the parts into several families based on the image captured from the vision sens...

In this issue of Pediatric Blood and Cancer, Wakefield et al. present the data on thequality of life,medication andhospitalizations of the grandparents of childrenwith cancer. Often grandparents play an important role of providing emotional and practical support for families affected by childhood cancer. Many of them try to support the families by taking over childcare duties for the siblings o...
