The intestinal epithelium follows the paradigms of stem cell biology established for other self-renewing tissues. With a unique topology, it constitutes a two-dimensional structure folded into valleys and hills: the proliferative crypts and the differentia ...
A review. Recombinant proteins are often expressed with an addnl. polypeptide the role of which is to aid purifn., detection, or functional studies. Recently, the role of these tags has been extended to mediate the labeling of the protein of interest with ...
We investigate the performance of sparsely-connected networks of integrate-and-fire neurons for ultra-short term information processing. We exploit the fact that the population activity of networks with balanced excitation and inhibition can switch from an ...
The :T-stacking of oxidized thiophene oligomers is investigated using extensive ab initio quantum chemistry methods. Dimers of singly charged oligothiophenes are unstable in the gas phase but can be stabilized as bound dications in the singlet state by a p ...
As a consequence of the co-evolution of business and information technology (IT), the responsibilities of software engineers are expanding. They are becoming much more involved in business-related issues. When defining computing curriculums, this trend nee ...
Halogenated organic compounds are common pollutants in groundwater. Consequently, there is widespread interest in understanding the reactions of these compounds in the environment and developing remediation strategies. One area of ongoing research involves ...
V groove GaAs/AlGaAs quantum wires are investigated by spatially resolved photoluminescence spectroscopy using a low-temperature scanning near- field optical microscope. The spectra along the wires feature several sharp emission lines, which are understood ...
There is a growing interest in the role played by attention and cognitive processing in the control of posture and gait, investigated by means of dual task methodology. The rationale for dual task testing is to assess whether the simultaneous performance o ...
Modern Information and Communication Technology open a door for innovations that can improve the functioning of companies. Many innovations can come from the analysis of business processes. Today modeling is widely used for the analysis of business process ...
Modeling approaches often are not adapted to human reasoning: models are ambiguous and imprecise. A same model element may have multiple meanings in different functional roles of a system. Existing modeling approaches do not relate explicitly these functio ...
