The paper describes the history of viscous-inviscid interaction methods, and tries to put them in a modern domain-decomposition context. This history started in 1904, when Ludwig Prandtl presented thèboundary layer' at the Third International Mathematical Congress in Heidelberg. From that moment on, the ow eld around a body was divided in two parts: a thin shear layer where viscosity plays a ro...

Cataract surgery is the most common elective operation performed worldwide (1, 2). The development of new technologies and new surgical techniques and materials lead to less invasive and day care procedures. This in turn encouraged an evolution on the ophthalmic anesthetic strategies, rendering general anesthesia largely unnecessary, so that local techniques have become preferred for cataract s...

Xbox Live Achievements and Gamerscores have become an important part of Xbox 360 gaming and have played an important role in the success of the console. Based on the framework provided by Microsoft, the community has created a rich and intriguing meta-game where the individual games become pieces of a larger whole. For every game released on the system, the developer has to define a number of a...

A necessary and sufficient condition for the existence of the general common positive solution to equations A1X = C1, XB2 = C2, A3XA ∗ 3 = C3, A4XA ∗ 4 = C4 for operators between Hilbert C-modules is established, and an expression for the common positive solution to the equations is derived when the solvability conditions are satisfied. As an application, a new necessary and sufficient conditio...

Agile microand nano-fluidic control is critical to numerous life science and chemical science synthesis as well as kinetic and thermodynamic studies. To this end, we have demonstrated the use of thin film transistor arrays as an active matrix addressing method to control an electrofluidic array. Because the active matrix method minimizes the number of control lines necessary (m + n lines for th...

Wearable devices with a wide range of sensors have contributed to the rise of the Quantified Self movement, where individuals log everything ranging from the number of steps they have taken, to their heart rate, to their sleeping patterns. Sensors do not, however, typically sense the social and ambient environment of the users, such as general life style attributes or information about their so...

Stereoselectively labelled isotopomers of NAD(P)H are highly relevant for mechanistic studies of enzymes which utilize them as redox equivalents. Whereas several methods are firmly established for their generation in high diastereomeric purity by enzymatic methods, alternative methods have so far not been investigated. The article presents the stereoselective deuteration of NAD at the 4-positio...

The cystolic sulfotransferse 1C3 (SULT1C3) gene was identified by computational analysis of the human genome and suggested to contain duplications of its last two exons (7a/b and 8a/b). Although the SULT1C3 isoform containing the more downstream exons 7b and 8b (SULT1C3d) has been expressed in Escherichia coli, crystallized, and characterized for activity, there is currently no evidence that SU...
