President's Pen: Collaboration instead of competition: 1 + 1 = 3

Competition and collaboration: GATA-3, PU.1, and Notch signaling in early T-cell fate determination.

T-cell precursors remain developmentally plastic for multiple cell generations after entering the thymus, preserving access to developmental alternatives of macrophage, dendritic-cell, and even mast-cell fates. The underlying regulatory basis of this plasticity is that early T-cell differentiation depends on transcription factors which can also promote alternative developmental programs. Interf...

Database Collaboration Instead of Integration

Database integration is currently solved only for the case of simple structures. Semantics is mainly neglected. It is known but often neglected that database integration cannot be automated. System integration is far more difficult. Both integrations can only be performed if a number of assumptions can be made for the integrated system. Instead of integrating systems entirely cooperation or col...

Ab Initio Study of Conformational and Configurational Properties of 1, 3- Diazacyclohepta-1, 2-diene and 1, 3-Diazacycloocta-1, 2-diene

Ab initio calculations at HF/6-31G* level of theory for geometry optimization and MP2/6-31G*//HF/6-31G* for a single point total energy calculation are reported for the importantenergy-minimum conformations and transition-state geometries of 1, 3-diazacyclohepta-1, 2-diene (2) and 1, 3-diazacycloocta-1, 2-diene (3). The C2 symmetric twist-chair (2-TC)conformation of 2 is calculated to be 7.4 kJ...
