The Chair of the IEEE Computer Society Technical Committee on Data Engineering (TCDE) is elected for a two-year period. The current Chair, Paul Larson, is unavailable to be a candidate. A Nominating Committee for electing a new chair for the period 2011-2012 consisting of Calton Pu, David Lomet and Erich Neuhold has been formed. The Nominating Committee invites nominations for the position of C...

One hundred twenty species of aleocharine beetles (Staphylinidae) are recognized in the province of Saskatchewan. Sixty-five new provincial records, including twelve new species and one new North American record, are presented. Oligota inflata (Mannerheim), a Palearctic species, is newly recorded for North America. The following twelve species are described as new to science: Acrotona pseudopyg...

We have investigated the evolution and distribution of molecules in collapsing prestellar cores via numerical chemical models, adopting the Larson-Penston solution and its delayed analogues to study collapse. Molecular abundances and distributions in a collapsing core are determined by the balance among the dynamical, chemical and adsorption time scales. When the central density nH of a prestel...

BACKGROUND Complex cartilage lesions of the knee including large cartilage defects, kissing lesions, and osteoarthritis (OA) represent a common problem in orthopaedic surgery and a challenging task for the orthopaedic surgeon. As there is only limited data, we performed a prospective clinical study to investigate the benefit of autologous chondrocyte implantation (ACI) for this demanding patien...

Paul Larson and Erich Neuhold are previous TCDE chairs and have served TCDE for many years revitalizing its activities. Their valuable experience will be greatly appreciated for promoting TCDE and for serving its members. David Lomet, a previous TCDE chair, has been Chief Editor of Data Engineering Bulletin since 1992. It is his leadership that has been at the heart of the success of IEEE Data ...
