Biochemical reaction networks are commonly described by non-linear ODE systems. Model parameters such as rate and equilibrium constants may be unknown or inaccessible and have to be identified from time-series measurements of chemical species. However, parameter identification is an ill-posed inverse problem in the sense that its solution lacks certain stability properties. In particular, model...

Heat transfer is a working area where different numerical results are obtained from materials, environments, independent observations made, data can be collected at bases based on the abundance of input. effects heat transfer. The air flow, temperature and pressure were discussed. Unlike previous studies, construction fin made aluminum choice NACA 4040 wing profile as shape was one major factor...

The Large Hadron Collider (LHC) is CERN’s next particle accelerator project, scheduled for commissioning in 2005. The project requires accurate current measurements above 10 kA. Calibration heads have been developed in collaboration with industry to work up to 24 kA at sub-ppm accuracy. The paper describes the design and verification. Presented at the CPEM’98 Conference, Washington, 6-10 July 1...

Luminous, sharply defined and nearly spherical objects (‘fireballs’), typically several centimetres in diameter, have been observed in Ar, Kr and Xe plasmas. The ‘fireballs’ are anchored on a disk anode biased et 4040 V above ground potential. They have been analysed in terms of a spherical double-layer model, in which ionizalion of the gas atoms by electrons energized at the double layer plays...

Rivenez et al. [J. Acoust. Soc. Am. 119 (6), 4027-4040 (2006)] recently demonstrated that an unattended message is able to prime by 28 ms a simultaneously presented attended message when the two messages have a different F0 range. This study asks whether a difference in vocal-tract length between the two messages rather than a difference in F0 can also produce such priming. A priming effect of ...

Adjuvant therapy for pancreatic cancer remains controversial. However, both sides of the Atlantic Ocean agree that at least gemcitabine should be the pivotal agent offered to all patients. The role of radiation therapy remains somewhat inconclusive but chemoradiation, whether in the neoadjuvant or adjuvant setting is a standard option often utilized in the USA. This review is an update from the...
